Slitting And Cutting Machine

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 with 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 ordinary tape cutters could not be high, because high-speed friction of magnetic powder was easy to occur during operation, resulting in high temperature and shortening its life. In severe cases, it would get stuck and hinder the operation of the machine. Seriously affected production efficiency. At present, the use of dual-frequency motor control makes the magnetic powder friction at a certain value under the condition that the diameter of the rolled material becomes larger. Without high temperatures. The traditional control scheme of tape cutting machining is to use a large motor to drive the winding and unwinding shaft. A magnetic powder clutch is added to the winding and unwinding shaft. The resistance of 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 clutches and brakes are a special type of automatic actuator. It transmits torque through the magnetic powder filled in the working gap. When the magnetic current is changed, the magnetic state of the magnetic powder can be changed, and the transmitted torque can be adjusted. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high-speed segment fine-tuning and small and medium power speed regulation systems. It is also used to adjust the torque by adjusting the current to ensure that the tension during the winding process remains constant during the unwinding or rewinding tension control system.
 
Three structural forms of tape cutter:
①Mechanical and pneumatic hybrid lifting mechanism: the sleeve equipped with the bottle holder can slide along the hollow plunger, and the square cushion block plays a guiding role to prevent the sleeve from deflection when lifting.
② Pneumatic bottle lifting mechanism: By using a pneumatic bottle holder, compressed air can be circulated in the ring pipe to reduce power consumption. Therefore, it has a self-buffering function, and the lifting is stable and saves time. ③Mechanical bottle lifting mechanism: This structure is relatively simple, but the working reliability is poor. The slice is raised along the slide, it is easy to squeeze the slice, and the slice quality is very high, especially the bottleneck cannot be bent, suitable for small semi-automation. Gas-free beef and mutton slicer. At the same time, the ordinary cutting machine is generally combined with the control of the cam guide to make the lifting movement of the slice fast, accurate and guarantee the quality. This kind of equipment is widely used, especially for the isobaric slicer, because it is equipped with air compression. Device, so this structure is more commonly used, the above are several common structural forms of the slicer.
 
Usually in the operation of the condensing microtome, if you encounter some small faults, you must learn to troubleshoot and analyze them yourself. For example, sometimes the common cutting machine will leak liquid. At this time, we must learn how to handle such faults. The main solution is:
 
1. First replace the sealing ring of the injection cylinder of the ordinary tape cutter;
2. Clean the pneumatic valve, and then replace the gasket of the pneumatic valve;
3. If there is also a small failure in the lower tube of the condensing slicer, the lower tube should be replaced;
4. Tighten the lower nozzle and replace the gasket of the lower nozzle. How to understand the needle problem of ultrasonic tape cutter. The problem of the needle of the ultrasonic tape cutter is as follows: During the process, the installation of the needle of the ordinary tape cutter is very important. If you need to sew different fabrics, you must choose different types of needles. When installing the needle of the ultrasonic tape cutting machine, be sure to correct it. If it is not correct, it will cause breaks and jumpers. If the same batch of products is produced, the needles used must be uniform, and the thickness and thickness cannot be mixed. Over time, the hook will be damaged, the hook will be abnormal, and the broken wire and jumper will occur. After long-term use of the ultrasonic tape cutting machine needle, the needle tip will be worn. If the needle is not pointed, it will cause thread breakage and bottom thread breakage, and it may also cause fabric thread breakage. Attention after Yaskawa's mechanical slicer finishes work: 1. Turn the hand wheel of the ordinary tape cutter, raise the specimen clamp directly to the position, and turn the hand wheel to stop the handle, and simultaneously move the specimen clamp and hand wheel Are locked. 2. Then directly remove the cutting blade from the knife holder, wipe it and place it in the knife box. 3. Remove the specimen directly from the tape-cut machined specimen holder. Fourth, clean up the residue on the slicer. Fifth, the whole machine is cleaned. Note: When using a slicing knife, we must be extra careful, because its blade is very sharp, if it is mishandled, it will cause serious injury. Do not directly touch the cutting blade with your hand, nor can you Random placement.
