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.

        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.
