1. During the production of the paper slitter equipment, due to the lateral warpage of the steel sheet, the width dimension is poor. This is because the product cut in the lateral warping state is measured more than the setting value of the knife.
2. During the operation of the paper slitting machine, if there is a problem of lateral swing of the tool, it will result in poor dimensionality, such as the lateral swing of the tool and the difference in the outer diameter of the tool. Since the lateral swing value of the tool cannot be zero. Usually the lateral swing value of its load is about 0.03-0.05 mm. The reason is the accuracy error of the blade thickness, the inner diameter, the spacer sleeve width, and the warpage caused by the lateral stress when the thick plate is sheared.
3. Because of the production operation of the paper slitting machine, there are certain fitting errors in the spacer sleeve and the cutter. In general, the thickness accuracy of the spacer sleeve and the tool is 0.005. When the number of pieces is large with the knife, the cumulative error becomes large. This is due to poor upper tolerance setting. It should be noted that the width of the product cut by the paper slitter is always slightly lower than the tolerance of the product side of the knife. Therefore, it is necessary to predict the degree of this difference in advance. Refer to the dimensions of the spacer sleeve when the knife is placed on the side of the product. The cutting method used is also considered later. In comparison, if the paper slitter is straight-pulled, the tension of the coil will increase, the lateral warp will disappear, and the size will go down.

1. Receiving mechanism and tensioning device: The receiving mechanism of the paper slitting machine is mainly composed of a chain, a synchronous wheel, a magnetic powder clutch and an air expansion shaft. As long as the adjustment is made, the two reels are controlled by a single motor. The current of the magnetic powder clutch can change the tension of the receiving shaft.
2. Paper slitter frame and transmission system: The paper slitter frame consists of left and right wall panels, support blocks and unloading mechanism. The drive system is mainly used to pull raw materials and wind the finished product. It is driven by a variable frequency stepless speed regulating motor through a motor V belt to drive the rubber roller. The main traction rubber roller and the driven traction rubber roller are in close contact with each other. The traction material is driven and the lower circular cutter shaft is operated synchronously by the active traction rollers for better cutting requirements. The lower circular cutter shaft drives the winding A and the winding B to perform synchronous operation to achieve the purpose of receiving the material.
3. Longitudinal cutter holder: The longitudinal cutter holder of the paper slitting machine has a circular knife slitting and a straight knife slitting. The operating handle allows the circular knife to move slightly axially, and the round blade and the cushion cover are adjusted by the planar cam. The shear gap of the groove.
4. Waste rewinding and discharge: The waste is discharged through the duct by the wind of the blower.
5. Traction member: The traction member of the paper slitting machine is mainly composed of a pair of traction rubber rollers and a plurality of hard alumina rollers, which are used for taking out the raw materials of the finished winding. Power is obtained from the motor through V. The belt is passed to the active traction roller for operation.
6. Discharge mechanism and automatic rectification: The discharge mechanism is mainly composed of a discharge shaft, a support block, a cylinder, a base, a left and right moving seat, etc., and is composed of an automatic correction device: a photoelectric opening, a correction guide roller, left and right brackets, a correction moving plate and a ball. . Nuts and screws, synchronous motor and left and right limit switches.

        1. If you encounter a problem that cannot be solved, first stop and ask for help. Never continue to run the machine under abnormal conditions.
        2. Safety production is a necessary premise, and safety must be paid attention to during operation.
        3. When adjusting the knife, first clean the dust with an air gun, and then carry out the knife adjustment process.
        4. For some problems with the base paper core, pay attention to the proper chuck clamping of the original paper core.
        5. Cut and pull out the air shaft, you must add support water pipes on both sides, pay attention to pull out the air shaft safely.
        6. When blowing, first stop the machine and put the paper into the tube, then restart
        7. When you encounter an abnormal problem, you must press the red button to stop the machine when you want to stop the machine. Develop the right emergency stop habits.
        8. In the case of padding, keep a certain distance from the plastic shaft and the paper tray to avoid injury.
        9. When the base paper passes the original paper, the paper roll must be stopped when the paper roll is over, and then the paper is adjusted.
        10 When using an air gun to clean the dust on the knife, first test the spray for a period of time to drain the water inside. If the gas from the air gun has water, use a rag to dry the shaft and continue.
         11. When dealing with the bad paper of the base paper, use the knife slide, be careful not to slip the inner paper.
         12. When blowing edges, pay attention to the stability of the flash when accelerating.
         13. When the original paper core is deformed and the base paper is rotated slowly, pay attention to the speed adjustment to slow down as much as possible.
         14. When the base paper is cut to the end, slow down the speed to avoid paper breakage.

        What is the cutting process of the paper slitter? Let's take a look at it together.
        1. Cutting, cutting a wide web into a plurality of narrow gauge materials;
        2. Cutting the edge and cutting off the process edge material reserved in the previous process, which is mostly used for the processing of composite film and other materials;
        3. Dividing the volume, dividing the large diameter material into several rolls of small diameter material, equivalent to rewinding and so on. These methods are sometimes used in combination. Regardless of the process used, the material after slitting should meet the corresponding technical specifications: dimensional requirements (refer to the width and length of the slitting material, etc.) and quality requirements (flatness of the coil, Surface quality, etc.).
        Manufacturing and purchasing qualified cutting equipment not only must meet these technical indicators, but also must consider the following two factors: operating efficiency, mainly including the working speed, stability and ease of operation of the equipment; economic performance, refers to the equipment pair The scope of application of the material, the processing limit size, as well as the price of the equipment, energy consumption, etc. With the continuous development of packaging technology and the improvement of packaging grades, the performance requirements of packaging materials for packaging materials have become increasingly prominent, and many materials with special properties have emerged, such as aluminized film with high light-shielding effect and high surface quality. A high-capacity CPP film, a multi-material composite film with high barrier properties. The continuous application of various new materials has promoted the rapid development of the flexible packaging market. The growth of market demand and the development of special application fields have made the requirements for slitting of packaging materials higher and higher, and the requirements for slitting equipment are becoming more and more demanding. On the other hand, with the gradual promotion of automated packaging equipment in the packaging industry, such as food packaging, cigarette packaging, etc., these quality requirements for the material after slitting are very critical, which gives the slitting machine a high-grade, high-precision Control brings a broad space for development.

        How to solve the problem of automatic cutting machine? The automatic slitting machine equipment plays a very important role in the paper processing industry. In the process of use, it is inevitable that failure will occur, which will cause certain obstacles to the production process, and the manufacturer will also suffer losses. If the staff pays close attention to routine maintenance, there is generally no problem. Let us talk about the following problems in the case of Ruian Maoyuan Machinery.
       Common troubleshooting methods for automatic slitting machine:
       1. The automatic slitting machine is not well-rolled, most of which is because the paper core is not suitable. It is only necessary to replace the paper core that meets the required inner diameter. In addition, during the winding process, the winding roller should also be used. Can avoid the problem of uneven winding.
        2. If the meter is not accurate, if you encounter such a problem, you can touch the feeding roller at the same time with the two wheels of the meter wheel, and make a mark on the meter wheel for 5 times to count 1 meter or replace the meter. .
        3. When the semi-finished product is slack in the middle, this is closely related to the unevenness of the gluing and the unevenness of the substrate. At this time, the bow roller should be adjusted to flatten it, or the tension of the reeling roller is increased, and the substrate is compacted by a knife tube.
        4. The semi-finished product generates wrinkles during winding, and the pressure of the tension cylinder can be appropriately increased.
        5. When the finished product is wound, the tension of the take-up shaft is too tight, or it is closely related to the glue when the glue is applied.
