Safe and environment-friendly foamed plastic shredder

Abstract

The invention discloses a safe and environment-friendly foamed plastic shredder. The shredder comprises a support, a shredding cavity body, a crushing mechanism and a feeding port opening and closingstructure used for opening or closing a feeding port of the shredding cavity body, wherein the shredding cavity body comprises a bottom plate, a side plate and a top plate, the feeding port opening and closing structure comprises a feeding bottom plate and a folding connecting structure used for connecting the feeding bottom plate and the shredding cavity body, the feeding bottom plate is mountedat the feeding port of the shredding cavity body through the folding connecting structure, and when the feeding bottom plate is turned outwards to open the feeding port of the shredding cavity body, the feeding bottom plate and the folding connecting structure form a guide hopper used for guiding foamed plastic to enter the shredding cavity body. According to the safe and environment-friendly foaming plastic shredder, the feeding port opening and closing structure is opened to be extended forwards, so that the safety protection effect is achieved, shredded foamed plastic is further prevented from escaping, and the feeding port opening and closing structure is closed, so that impurities are prevented from entering the shredding cavity body, and the size of the shredder is reduced.

Description

technical field [0001] The invention relates to recycling equipment for environmentally friendly foamed plastics, in particular to a safe and environmentally friendly foamed plastic shredder. Background technique [0002] Foamed plastics such as EPS, XPS, and EPP have good properties such as heat insulation, sound insulation, rigidity, good impact cushioning performance, corrosion resistance, and low density. They are widely used in product packaging, heat insulation, sound insulation, and impact resistance. However, even though used foamed plastics have a high recycling value, due to their low density, the collection process takes up a lot of space and the transportation costs are heavy, making recycling difficult. The current recycling status is that the collected foamed plastics are sent to a cold press for cold pressure reduction, or heating and melting to remove air for volume reduction, and then transported to the deep processing plant for modification and other proces...

Problems solved by technology

Because the factory strictly prohibits operators without safety training from operating the machine; however, the vehicle-mounted system works in a mobile place. Although the operators are well-trained, it is inevitable that passers-by will be surprised or curious, approach the machine or even fiddle with the machine when the operator walks a little, thus There are security risks;

[0007] 3. During the process of crushing the foamed plastic by the rotation of the crushing hob, due to the rotation of the crushing hob, it is easy to generate a turbulent airflow in the crushing chamber, and it is easy to wash away the broken foamed plastic particles in the crushing chamber. The escape of the feed port of the crushing cavity not only causes waste, but also easily pollutes the environment and endangers the health of the operator;

[0008] 4. When the crushing device is shut down for a short time, since the crushing device of the foam plastic recovery vehicle is not provided with a device for opening or closing the feed port of the shredding chamber, such as a gate , so other sundries may enter the crushing cavity from the open feed port, thereby affecting the normal operation of the crushing device, and even damage the crushing device in severe cases
