Pipe shredder as a waste plastic processing and recycling equipment relative to the plastic crusher The machine is more simple and convenient in the structure, pipe shredders can generally be used to deal with unprocessed raw materials or scrap, to make it smaller size. A representative example is the plastic pipe or rubber pipe after the scraping material as raw materials after melting and granulation. Large pipe shredders are usually uniaxial shredders, through the spindle on the insert of the blade on the spindle near the rubber pipe to achieve scraping and tearing operations, through the advance of the pusher plate will gradually reduce the thickening of the rubber tube in the final push The size of the material can be limited according to the size of the material, but taking into account the production problems and efficiency problems such as crushing can be configured in the machine after the plastic crusher in order to achieve high yield and high efficiency characteristics The

Performance characteristics of pipe shredder

1. Pipe shredder knife and blade removable, easy to clean, maintenance, maintenance;
2. Pipe shredder Each knife has four cutting edges, can be rotated after 90 ° to continue to use;
3. Pipe shredder spindle driven by the gear box, running smoothly, low noise, high torque;
4. Pipe shredder using PLC program control system, can automatically reverse, so that the machine running more secure and reliable;
5. Pipe shredder box with welding, welding tempering treatment, eliminating the welding stress;
6. Pipe shredding The position of the moving knife is machined by the machining center to ensure that the clearance between each knife and the knife is the same.
7. Pipe shredding machine tool holder with embedded way with high-strength screw connected to the knife shaft, which can effectively prevent the welding in the long-term vibration after the knife out of the phenomenon;
Pipe shredder mechanism principle
Large diameter pipe shredder in the equipment structure mainly by the motor, hardened surface reducer, rotary knife shaft, imported knife, knife, rack, frame, box, hydraulic cylinder, oil pump, cylinder and other major Structure and composition. Rack on the set knife, rotating knife shaft equipped with removable embedded knife, the number of knives according to the different models and the size of the rotary knife shaft, and the knife is a four corners can be used knife, Under the angle of change, until the four sides with blunt and then sharpening, because it is a claw knife, rotary cutting, and fixed knife and knife is imported from Japan SKD11 material, after heat treatment hardness of HRC60 ° above, so long service life , Cutting capacity, high capacity, the normal use of more than 1,000 tons only need to sharpen. The machine is powered by a hydraulic cylinder and is equipped with a pneumatic clamping device. Henan Shangzheng machinery in the equipment control using PLC programmable control, high degree of automation, easy to operate. In the whole operation process only need to start the large diameter pipe shredder and the feeder in the material into the cavity after the hydraulic push plate driven by the material near the spindle, through the continuous cutting of the material will gradually reduce the material until the crushing is completed , Can also continue to add during the period. Henan is still mechanical large diameter pipe shredder in the composition of the equipment can be divided into the following parts:
1, the host cavity for the pipe shredder to provide closed processing environment, limiting the direction of broken materials for the spindle load and shaft box to provide the basis for the installation.
2, the spindle sticks through the spindle sticks by bolts fixed blade on the material to cut, tear broken
3, shaft box bearings to reduce the spindle blade friction resistance for the equipment to provide the basis for high-speed operation.
4, the reducer on the motor speed to slow down the equipment running torque, improve the equipment encountered in the metal material when the impact resistance.
5, push material system The system consists of hydraulic pump, valve, cylinder and other components, mainly for the broken material to provide a relatively fixed pressure.
6, the control cabinet system is mainly for the single-shaft shredder to provide power control, through the valve, safety control switch commutation, speed, close the device to achieve automatic protection and feeding system for normal use
