The paper slitter rewinding includes an upper rewinding roller, a lower rewinding roller, a rear rewinding roller, and a pressing roller having the same linear speed as the rear rewinding roller, which is characterized in that the pressing roller is on the base paper. The rewinding and upper rewinding rollers speed up and pull off the base paper in a timely manner, after being driven by a driving tissue to open and close contact with the rear rewinding roller.
        In the course of operation, if the paper slitter shows rewinding problems, it can proceed from the following three aspects:
        1. When the coiled product runs, whether the tension of the coiling shaft is too tight, or is closely related to the glue when gluing;
        2. When the semi-finished product is wrinkled during winding, the pressure of the tension cylinder can be increased appropriately;
        3. When the center of the semi-finished product is loose, this is closely related to uneven gluing and uneven substrate. At this time, adjust the bow roller to support it, or increase the tension of the unwinding shaft, and use the knife tube to compact the substrate.
        However, what should be done if the problem is not caused by mechanical operation during normal operation, but when the processing plant area shows a power outage?
        1. Block the power switch in time to prevent accidental incoming calls and unnecessary damage.
        2. Immediately sort the paper in the paper slitter. Because of the power failure, a part of the residual paper is formed in the machine. In order to prevent the residual paper in the paper slitter from affecting the future production.

        How does the automatic slitting machine work? Let's take a look below.
        1. It needs to cut the entire roll or the whole material with a fixed length. For example, some steel plates, leather, wood chips and some packaging materials need the help of the cutting machine, and all the cutting control is used.
        2. The cutting control of the automatic cutting machine is divided into static and dynamic. It will stop after the set length is reached, and then perform static processing; after the set length is reached, the cutting machine will send a signal to cut The machine will perform dynamic slitting during material movement.
        3. The slitting length can be set continuously. If there is an error in the actual slitting length, it can be calibrated by setting parameters.
        The above is the working mode of the automatic slitting machine.

        How to choose a high-quality automatic slitting machine? What should we start from? Let's take a look with the slitting machine manufacturers.
        1. First of all, we have to choose a fully automatic slitting machine that is suitable for our own materials. In fact, it is the production accuracy and speed, because the most hope for the material in the slitting process is to improve production efficiency and product quality.
        2. When buying a slitter, it is best to directly inspect it yourself, and effectively make your own judgment on the observation of the enterprise to remove the external objective influence, which will greatly reduce the purchase risk.
        3. The choice of slitting machine depends on the manufacturer, followed by the brand. The reason why manufacturers with many years of operating experience still exist is because there is a market, there are customers in the market, and customers are the products that are relatively satisfactory to the customers, and the product quality is relatively guaranteed. Secondly, it should be selected according to the brand. Generally, mainstream brands have a good quality foundation and are favored by customers.
        The above is the method to choose the automatic slitting machine, I believe everyone already knows.

         The paper slitter is composed of various components, so what is the main role of these components?
         1. Receiving mechanism and tensioning device: The receiving mechanism of paper slitter is mainly composed of chain, synchronous wheel, magnetic powder clutch and air expansion shaft. As long as adjustments are made, the two reels are controlled by one 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 is composed of left and right wall plates, support blocks and discharge mechanism. The transmission system is mainly used for pulling raw materials and winding finished products. It is driven by the variable frequency stepless speed regulation motor through the motor V belt to pull 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 blade shaft is synchronously operated by the active traction roller to achieve better cutting requirements. The lower circular cutter shaft drives winding A and winding B to perform synchronous operation, so as to achieve the purpose of receiving material.
        3. Slitting knife holder: The slitting knife holder of paper slitting machine has circular knife slitting and straight knife slitting. The operating handle can make the circular knife move slightly axially, and the circular blade and cushion can be adjusted by the plane cam. Groove shear gap.
        4. Waste rewinding and discharge: use the wind of the blower to discharge the waste through the air duct.
        5. Traction member: The traction member of the paper slitter is mainly composed of a pair of traction rubber rollers and multiple hard aluminum oxide rollers, which are used to take out the raw materials of the finished product. Power is obtained from the motor through V. The belt is transferred to the active traction roller for operation.
        6. Discharge mechanism and automatic rectification: the discharge mechanism is mainly composed of discharge shaft, support block, cylinder, base, left and right moving seats, etc., and is composed of automatic correction device: photoelectric opening, correction guide roller, left and right bracket, correction moving plate and ball . Nuts and screws, synchronous motors and left and right limit switches.
        The above are the components and functions of the paper slitter.

        When the paper slitter is working, sometimes the size will be inaccurate, what is the main reason for this?
        1. During the production of paper slitter equipment, due to the problem of horizontal warpage of the steel plate, it caused a poor width dimension. This is because the product cut in the lateral warpage state is larger than the setting value of the knife.
        2. During the operation of the paper slitter equipment, if the cutter has a problem of lateral swing, it will result in defective dimensions, such as the lateral swing of the cutter and the different outer diameter of the cutter. The value of the tool's lateral oscillation cannot be zero. Usually the lateral sway value of the load is about 0.03-0.05mm. The reason is the accuracy error of knife thickness, inner diameter, spacer sleeve width, etc., and the warpage caused by the lateral stress when the thick plate is sheared.
        3. Due to the production and operation of the paper slitter equipment, there is a certain matching error between the spacer sleeve and the cutter. Normally, the thickness accuracy of spacers, cutters, etc. is 0.005. When the number of blades is large when the knife is matched, the cumulative error becomes larger. This is due to poor upper tolerance setting. It should be known that the width of the product cut by the paper slitter is slightly lower than the size of the product side with the knife. Therefore, it is necessary to predict the degree of this difference in advance. Refer to it when determining the size of the spacer when matching the knife on the product side. Later, the shearing method used must also be considered. In comparison, if the paper slitter equipment uses straight-pull shear, then the tension of the steel coil will increase, the lateral warpage will disappear, and the size will also go down.
        All in all, there are many reasons for the inaccurate size of the paper slitter. We should check the reasons in time and then solve them.
