The slitting machine is a pre-press and post-press equipment that cuts a large roll of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into small rolls of different widths. It is often used in papermaking machinery and printing and packaging machinery. In the past, the speed of the magnetic powder clutch of the ordinary cutting machine could not be high, because the high-speed friction of the magnetic powder was easily caused during operation, high temperature was generated, and its life was shortened. In severe cases, it would jam and hinder the operation of the machine, which would bring serious consequences to production. Seriously affect the production efficiency. At present, it adopts dual frequency conversion motor control, which makes the magnetic powder friction at a certain value by the frequency conversion motor control when the diameter of the winding material becomes larger. Without high temperature. The traditional control scheme of cutting machine processing is to use a large motor to drive the rewinding and unwinding shaft. A magnetic powder clutch is added to the rewinding and rewinding shaft. The resistance generated by the magnetic powder clutch is controlled by adjusting the current of the magnetic powder clutch to control the surface of the material. tension. Magnetic powder clutch and brake are a kind of special automatic actuators, which transmit torque through the magnetic powder filled in the working gap. Changing the magnetic current can change the magnetic state of the magnetic powder and adjust the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed, suitable for fine-tuning of high-speed section and speed regulation system of medium and small power. It is also used in the unwinding or rewinding tension control system to adjust the torque by adjusting the current to ensure that the tension remains constant during the winding process.
Three structural forms of Wanying belt cutting machine:
①Mechanical and pneumatic hybrid lifting mechanism: the sleeve with the bottle holder can slide along the hollow plunger, and the square block plays a guiding role to prevent the sleeve from lifting Deflection occurred.
②Pneumatic bottle lifting mechanism: The compressed air can be recycled in the loop tube by using the pneumatic bottle to reduce power consumption, so it has a self-buffering function, the lifting is stable, and it saves time. ③Mechanical bottle lifting mechanism: This kind of structure is relatively simple, but its working reliability is poor. The slices rise along the slide, and it is easy to squeeze the slices. The quality of the slices is very high, especially the bottleneck cannot be bent, which is suitable for small semi-automatic The gas-free beef and mutton slicer. At the same time, ordinary cutting machine processing is generally combined with the control of the cam guide, so that the lifting movement of the slice is fast, accurate, and the quality is guaranteed. This kind of equipment is widely used, especially for the isobaric slicer, because it has been equipped with air compression Device, so this structure is more commonly used, the above are several common structural forms of slicers.
Usually in the operation of the condensate slicer, if you encounter some small faults, you must learn to check and analyze them yourself and then solve them. For example, sometimes there is a leakage of ordinary cutting tape. At this time, we must learn how to deal with such faults. , The main solutions are:
1. Replace the sealing ring of the injection cylinder of the ordinary cutting machine;
2. Clean the pneumatic valve, and then replace the sealing gasket of the pneumatic valve;
3. If the discharge tube of the condensing slicer is also found In case of minor faults, replace the feed tube;
4. Tighten the feed nozzle and replace the sealing gasket of the feed nozzle. How to understand the needle problem of the ultrasonic tape cutting machine. Wanying Machinery Co., Ltd. reported to some customers about the needle problems of the ordinary tape cutting machine; the editor of Wanying answers the needle problems of the ultrasonic tape cutting machine as follows: During the process, the installation of the needle of the ordinary tape cutting machine is very important . If you have to choose different types of needles when sewing different fabrics. When installing the needle of the ultrasonic tape cutting machine, it must be properly installed. If it is not correct, it will cause wire breakage and wire jumper. If the same batch of products are produced, the needles used must be uniform, and the thickness cannot be mixed. Over time, the hook will be damaged, causing abnormal thread hooking, and thread breakage. The needle of the ultrasonic tape cutting machine will wear out after a long time. If the needle is not pointed, it will cause the thread to jump and the bottom thread, and it may also cause the fabric to break. Points for attention of Wanying mechanical slicer after finishing work: 1. Rotate the hand wheel of the ordinary cutting machine, raise the specimen holder directly to the position, and turn the hand wheel to stop the handle, and simultaneously place the specimen holder and hand The wheels are locked. 2. Remove the cutting blade directly from the knife holder, wipe it clean, and place it in the knife box. 3. Remove the specimen directly from the specimen holder of the cutting machine. Fourth, clean up the chips on the slicer. Fifth, it is to clean the whole slicer. Note: When using the slicing knife, we must be very careful, because the blade is very sharp, and it will cause serious injury if it is mishandled. You should not directly touch the cutting blade with your hands, and you should not touch the cutting blade. Randomly placed.
