Description

a pulverizer

technical field

The utility model relates to the processing and production of injection molding products, in particular to a pulverizer.

Background technique

Injection molding is a method of producing modeling for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine is the main molding equipment for thermoplastics or thermosetting plastics to use plastic molding molds to make plastic products of various shapes. Injection molding is realized by injection molding machines and molds. Adjusted and defective products often appear in injection molding. Such products and waste materials such as material handles can be reused (nozzle material) after being crushed. Therefore, a crusher for crushing such products has emerged. Most of the existing crushers are used. Only a single pulverization is performed, and in order to reduce the force of the pulverizing device and prolong the service life, there is usually a gap in the pulverizing area. Therefore, some material handles or large pieces of waste pass through the pulverizing area and enter the collection area, which affects the subsequent secondary use.

For example, a "automatic pulverizing device for injection molding waste" disclosed in the Chinese patent document, its bulletin number CN107984647A, includes a feeding mechanism, a feeding mechanism and a pulverizer, and the inner side of the pulverizer is provided with a third rotating shaft, The right end of the third rotating shaft is provided with a transmission and a second motor, a stirring mechanism is installed on the third rotating shaft, a feeding pipe is installed on the top of the pulverizer, a feeding hopper is installed on the upper end of the feeding pipe, and an outlet is installed on the bottom of the pulverizer.
