At present, there are many types of slitting machines, but they are generally semi-automatic, so with the market demand, the future development must be toward fully automatic slitting machines. Why do you say that?
        1. Fully automatic and fast. Our manual operation often requires debugging, which invisibly reduces work efficiency. As a fully automatic operation, only one button is required to operate and the operation is accepted. This entire process can even be left unattended. If we compare now, I believe the speed is reliable.
        2. Simple operation, easy to learn and use. I do n’t know if people are lazy now or what is going on. Most people like simple things. The simpler the things, the easier it is to be accepted. Therefore, if the operation is simple, it will be a strong competitiveness. Did you say that?
        3. Machine operation is not easy to go wrong. As long as the machine has no clumsiness and mistakes, even if there is a problem, the machine will automatically stop working.

        Paper slitting machine is a very popular kind of slitting machine. The following editor will introduce the main features and defects of the paper slitting machine.
        The main feature of the slitter is that the magnetic powder clutch is installed as a resistance. After system control, a DC voltage is output to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive installation that can control less tension.
        The main drawback is that the speed cannot be high, and high-speed friction of magnetic powder is easily formed during high-speed operation, which generates high temperature, which causes the magnetic powder clutch to generate heat and shorten its life. Use a knife to cut the roll of a certain width longitudinally and cut it into several narrower rolls for installation. After it is installed in the calender, extruder, glue applicator and other units, it can complete continuous strip cutting, often with winding installation. Strip cutter can be used flat knife and round knife.

        During the operation of the paper slitter, we need to understand some of its technological requirements, so that the working efficiency can be effectively improved. The following slitter manufacturers introduce the technological requirements of the paper slitter.
        Process requirements:
        1. The paper slitting machine needs to cut the entire roll or the whole raw material with a fixed length, such as plastic packaging materials, packaging cartons, steel plates, films, leather, wood chips, etc., and must use fixed-length cutting. control.
        2. Fixed-length slitting control is divided into static and dynamic slitting: when the set length is reached, it will stop accurately, and then the static slitting process will restart after the slitting; when the set length is reached, it will be issued without stopping. Slitting signal, paper slitting machine dynamically slitting process during material movement.
        3. The paper slitting machine manufacturer stated that the most important performance index of fixed-length slitting is slitting accuracy, and the consistency of finished product length is good.
        4. The cutting length can be set continuously. If there is an error in the actual cutting length, it is easy to calibrate by setting parameters.

        Careful friends will find that the paper slitter has a floating roller. Many people don't know its function. The following slitter manufacturers will introduce the role of the floating roller of the paper slitter.
        The floating roller adopts vertical up and down movement, which can not only form tension on the rewinding material, but also improve the accuracy, reduce the volume and reduce the cost. It adopts the precision guide rail set vertically on the inner side of the wall plate, the floating roller connecting seat is moved and set on the precision guide rail pair, one end of the piston rod in the cylinder is connected to the wall plate, the other end is connected to the floating roller connecting seat, and the floating roller ends The floating roller connecting seat is connected, and one end of the sliding rheostat is connected to the floating roller connecting seat.
        The application of the floating roller solves the defects that the horizontal swing in the prior art must overcome the weight of the roller, the inconsistency with the tension direction of the paper slitter, the low accuracy, the inability to improve, and the large size of the entire mechanism.

        The high-speed slitter will encounter many quality problems during the slitting process. What are they?
        1. Vertical stripes
        The main performance is that the surface of the film roll is formed with circular rib-like stripes. In the process of slitting and rewinding of high-speed slitter, a large amount of air entrapment and poor accumulated thickness tolerance are the main reasons for the longitudinal stripes. Once the more serious stripes appear, it is difficult to eliminate.
        2. Bottom wrinkle
        This problem only occurs in the length of the beginning of film winding, which is mainly manifested as wrinkling and deep streaks. The causes are caused by a variety of factors.
        3. Brutality
        This quality problem is due to the obvious protrusions formed on the surface of the film roll due to the accumulation of film thickness tolerances.
        4. Warping
        This quality problem occurs at the edge of the film winding, which is caused by the edge of the thick film being curled and superposed.
        5. Split Level
        Refers to the phenomenon that part of the film is staggered on the end surface of the film roll. This problem is mainly caused by the film sliding or the width of the film changing during the winding process.
        6. Insufficient length and excessive width
        This quality problem is caused by wrong winding count or insufficient length of slit film and incorrect positioning of equipment.
        The above are the quality problems that will occur during the slitting process of the high-speed slitting machine.
