Injection molding machine side crusher is a peripheral equipment of the injection molding machine, mainly used to crush and recycle defective products and sprue materials produced by the injection molding machine. The following is an introduction to it:
Working principle
The motor drives the moving knife disc to rotate at high speed, and relative movement and gap are formed between the moving knife and the fixed knife, resulting in the incision of plastic crushing and shearing, breaking large pieces of plastic, and then filtering and outputting the crushed plastic through the screen according to the particle size.
Equipment features
Cost saving: The sprue material can be immediately crushed and recycled into the injection molding machine for recycling, reducing the input of new materials, reducing the cost of raw materials, and also saving the cost of waste transportation.
Improve efficiency: It can crush the waste generated by the injection molding machine immediately without affecting the normal production process, and the crushed material particles are uniform, and the mixing effect with the new material is good, ensuring the stability of product quality, reducing the defective rate, and improving production efficiency.
Environmental protection and energy saving: It realizes the recycling and reuse of waste materials, reduces the emission of plastic waste, and meets environmental protection requirements; some crushers also adopt energy-saving design to reduce energy consumption.
Easy to operate: compact structure, beautiful appearance, easy to operate, some also have easy-to-disassemble design, convenient to change color and material.
Types and features
Slow-speed Injection molding machine side crusher: low speed, low noise, uniform crushed particles without powder, the whole machine has no screen design and does not need to change the screen, the extraction type cleaning design is convenient for cleaning, the nozzle material can be automatically recycled, and the knife group adopts coarse crushing and fine crushing simultaneously.
Medium-speed Injection molding machine side crusher: usually placed next to the plastic molding machine, it can work with the manipulator to quickly crush the nozzle material into particles, and send it back to the plastic molding machine for recycling through the recycling device. The unique knife holder design and high-quality knife combination make the crushed particles uniform and less powder.
Knife type classification
Claw knife plastic crusher: suitable for crushing and recycling of various plastics, better for hard plastics, optimized knife holder design, claw knife can disperse the force, improve the cutting force of the knife and reduce wear.
Flake knife plastic crusher: The structure of the blade knife is between the claw knife and the flat knife. It is suitable for crushing ordinary sheets, pipes, profiles, plates and packaging materials and other plastic products, nozzle materials, and the product is uniformly granulated.
Flat knife plastic crusher: The parallel knife is wide, suitable for crushing large-volume thin-walled and thin-material products, improving the crushing efficiency, with an electronically controlled safety design, the hopper adopts a double-layer structure, filled with sound insulation materials, and has good safety and environmental protection.
