Pulverizer for plastic production

Abstract

The invention discloses a pulverizer for plastic production. The pulverizer structurally comprises a motor, a dustproof cover, a pulverizer body, a feeding port and a discharging port, wherein the output end of the motor is mounted in the dustproof cover; the upper end of the dustproof cover is mounted outside the pulverizer body; the feeding port is fixedly formed in the upper end of the pulverizer body and communicates with the pulverizer body; and in the process that a phenolic plastic shell is in contact with shifting plates, the moisture of phenolic resin in phenolic plastic is primarilydried through heating rods, then, the moisture in the phenolic resin is absorbed by silica gel in a storage box in the rotating process of rotating rollers, and the moisture in the phenolic plastic iseffectively removed. According to the pulverizer for plastic production, a rotating shaft rod rotates to drive movable cutters to rotate for cutting, the phenolic plastic shell is preliminarily pulverized, and a buffer distance is formed between hammer bodies and the cylinder wall through springs arranged between swing rods and the hammer bodies, so that the hammer bodies are prevented from excessively extruding fine phenolic plastic, and the phenolic plastic is prevented from being dissolved in the pulverizing process.

Description

technical field [0001] The invention relates to the field of plastics, and more specifically relates to a pulverizer for plastic production. Background technique [0002] Phenolic plastics are made of phenolic resin, and are the most commonly used thermosetting plastics for the outer casings of low-voltage electrical appliances. When recycling waste low-voltage electrical appliances, the outer casings of phenolic plastics need to be crushed to facilitate the production of plastic particles. , but because the phenolic resin has a certain hygroscopicity, the pulverizer and the phenolic resin will rub against each other during the pulverization process of the phenolic plastic, causing the pulverizer to exert a certain pressure on the phenolic resin, and the softening point of the phenolic plastic is around 90°C , when the temperature is lower than the softening point, such as applying pressure and containing a certain amount of water in the phenolic resin, it is easy to cause t...
