The large-scale production of paper bag products is a large number of simple and important tasks. If manpower is used, the production efficiency and cost control cannot be satisfactory. The paper bag machine that can realize automatic production is exactly the solution to this problem. Below we will Let's introduce how the paper bag machine can realize automatic control.
The general paper bag machine is mainly composed of a storage device, a stepping device, a frequency conversion device, a whole bag device, a heat sealing cutter and a control device. The main feature of the paper bag machine is that the storage device stores the corresponding amount of raw materials, the stepping device drives the raw materials, the inverter device drives the heat sealing cutter, the whole bag device produces the whole bag after the fixed number of bags are produced, and the heat sealing cutter controls its temperature through the thermostat Seals and cuts the raw materials, and the control device coordinates all aspects of the operation. In this way, the automatic production of equipment is realized.
Below we introduce the main control methods of the paper bag machine:
1. Turn on the discharge switch and control the movement of the storage motor through the storage photoelectric to store the quantitative material.
2. Turn on the heating control switch and warm the hot knife through the thermostat.
3. The stepping motor drives the movement of the raw materials. The white bag sealing and cutting is to determine the stepper motor to stop for a fixed number of steps to achieve fixed-length control. The color bag sealing and cutting is to stop the stepping motor by detecting the corresponding signal to detect the positioning of the motor.
4. After the stepping motor stops, the three-phase asynchronous motor drives the hot knife to seal and cut.
5. After sealing and cutting the number of bags, carry out the whole bag.
Now the production of packaging equipment has a good scale. At present, it has entered a new height in terms of equipment efficiency, precision, automation, etc., and the gap with international advanced technology is even smaller. Now we need more innovation to get out of our own The road to development.
The big boxes are transported to a cartoning bag making machine and stacked, and when they reach a predetermined quantity, they are loaded into the opened box. After packing, the box lid is glued and sealed by a box sealing and sticking paper bag machine, and the box is glued with tape or the paper bag machine is used to bind the box firmly. Liquid filling paper bag machine and its assembly line are divided into normal pressure filling paper bag machine, pressure filling paper bag machine and vacuum filling paper bag machine according to the filling principle.
① Atmospheric pressure filling paper bag machine: It is filled by liquid's own weight under atmospheric pressure. This type of filling paper bag machine is divided into two types of regular filling and fixed volume filling, which is only suitable for filling low-viscosity liquids such as milk and wine.
② Pressure filling paper bag machine: It is filled under the atmospheric pressure, which can be divided into two types: one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and the liquid is poured into the bottle to fill it by its own weight. It is called equal pressure filling; the other is that the pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle by the pressure difference. High-speed production lines mostly use this method. Pressure filling paper bag machine is suitable for filling liquid containing gas, such as beer, soda, champagne, etc.
③Vacuum filling paper bag machine: Filling is performed when the pressure in the bottle is lower than the atmospheric pressure. This filling paper bag machine is simple in structure, high in efficiency, and suitable for a wide range of viscosity of materials, such as oil, syrup, fruit wine, etc. Is a block diagram of the liquid filling process. Boxes filled with empty bottles are stacked on pallets and sent to the unloading paper bag machine by the conveyor belt. The trays are unloaded one by one. The boxes are sent to the unloading paper bag machine with the conveyor belt. The empty bottles are taken out of the box. The conveyor belt is sent to the carton-washing paper bag machine, cleaned, and then conveyed to the carton-loading paper bag machine, so that the bottles containing beverages can be filled therein.
The empty bottles taken out of the unloading paper bag machine are sent to another bottle washing paper bag machine for disinfection and cleaning by another conveyor belt. After being inspected by the bottle inspection paper bag machine, they will enter the filling paper bag machine and cap paper bag machine after meeting the cleaning standards. Beverages are filled into bottles by filling paper bag machines. The filled bottles are sealed by a capping paper bag machine and conveyed to a labeling paper bag machine for labeling. After the labels are labeled, they are sent to the carton paper bag machine into a box and then sent to a stack of paper bags. warehouse.
The process of bottle filling line for various beverages is basically similar. However, due to the different nature of the beverage, the filling paper bag machine and the capping paper bag machine are also different. For example, in addition to the selection of suitable filling and capping paper bag machines for beer filling lines, a sterilization paper bag machine is also added. The paper bag sealing machine is selected according to the shape of the cover (crown cap, screw cap, plug cap, etc.).
The upper and lower films are forbidden The upper and lower films are forbidden refers to the problem that occurs when the front and back sides are not aligned when the bag is made. The compound film is uneven in thickness and has lotus leaves. Double lift roller tension is too small, the roller does not rotate smoothly. Solution: Check and adjust the relevant guide rollers (such as offset rollers, deflection rollers, etc.).
Adjust the tension of the double-floating roller. There are variegated on the cover, air bubbles, variegated on the cover, and air bubbles are the cause of uneven sealing surface. When heat-sealing a structure that is rich in hygroscopic raw materials such as nylon films, the hygroscopic film absorbs moisture and generates bubbles. Lack of heat seal pressure.
Use single-component adhesives, such as neoprene adhesives, when heat-sealing bags. Hot covers can easily show uneven pits. Solution: Replace the adhesive. View or adjust heat seal knives and heat seal silicone pads. Store raw materials and semi-finished products properly to prevent them from absorbing moisture.
Scale errors occur due to operational factors such as improper tension control, lack of pressure setting for the pressure roller of the film-feeding rubber roller, etc. Electric eye tracking is forbidden. Influence of processing speed of plastic composite film bag making. The bag making mechanism has a poor bag length and fixed length system.
Solution Reduce the speed of bag making, and adjust the speed of bag making slowly. The pre-adjusted film feeding length (when adjusting the white bag) and the actual bag-making scale should be as accurate as possible. Check the compression degree of the compressed film ruler and whether the friction coefficient of the composite coating is appropriate. Adjust the pressure of the film-feeding rubber roller, the cylinder pressure and the tension of each part to see if there is a question about the cursor printing or distance, and adjust it.

Color mark tracking system: The precise color mark tracking system ensures the accuracy of the cutting position of the printed pattern on each paper bag. The color mark automatic alignment function eliminates the need to readjust the cutting position after changing paper rolls, paper cuts, and power failures. Automatic shutdown of color label errors saves valuable time and reduces scrap rate.
Hot-melt adhesive spraying system, hot-melt adhesive spraying can make paper and plastic, paper and paper and other materials stick more firmly, and it will not be glued when stored at low temperature. The integrated tube-shaped adjustment structure and the integrated tube-shaped adjustment structure improve the working efficiency, reduce the waste rate generated during the adjustment process, and save adjustment time and adjustment stability.
On-machine automatic feeding (paper) device, on-machine automatic feeding (paper) device, the feeding can be done easily by just touching the switch, to avoid possible personal injury caused by manual feeding. The feeding of the machine ensures the stability of the discharge, and avoids the phenomenon that the discharge rack is shifted due to the displacement of the discharge rack.
In order to achieve high-speed and stable operation during the production process of the multifunctional paper bag machine, it is necessary to pay attention to the following: the unloading and dragging must be stable: the unloading swing roller cannot be too high or too low, and the dragging cannot be too loose or too tight. These conditions will cause radial jitter during the operation of the material, which will cause inaccurate tracking of the front and rear and discharge color-coded photoelectric eyes, and the length of the bag will be wrong. It will also cause the length of the bag to be stretched. Adjust the size of the air pressure of front, rear and unloading roller.
The temperature setting is appropriate: too high temperature will cause the product to wrinkle and affect the tracking of the optoelectronics, resulting in different bag lengths. At first, the sensitivity of the optoelectronics can be increased. After the temperature stabilizes, reduce the sensitivity so that the tracking fails. Choose the right temperature for different products.
The material produces abnormal noise during the operation. First of all, it is necessary to eliminate the problem of the mechanical part, then you need to observe whether it is generated after acceleration. The noise generated after acceleration will appear in: the hot knife is too low or the hot cloth is too loose. Plastic mud, the setting speed of the material is low, the tension between the two rubber rollers is too small, and the tension of the material is too high. The improper setting of the motor speed will cause the motor load to mismatch with the host speed. The tension between the two rubber rollers is too small. It will also be tightened tightly, at this time the motor load will also increase, and the inertia when starting and stopping will bring a sound.
Exhaust during the operation of the material: The exhaust is not clean, and the residual air in the material will cause the overall deformation of the bag, affecting the normal operation of the material, and there will be a certain sound. Appropriate compaction of the relevant bead is required. The edge-sealing ironing cloth should not cause any additional resistance due to the adhesion between the material and the ironing knife.
The effect of temperature on photoelectricity: The temperature of the hot knife is working without moving. When the machine is turned on again, the temperature will appear too high, the seal will deform, the bag will expand and contract, and the distance between the bag and the photoelectric will naturally cause tracking failure. Or frequent failures. In severe cases, the material will also have a glass transition temperature, which will cause pollution to the hot cloth and affect the operation and quality.
