Problems solved by technology

[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 the phenolic resin contains a certain amount of water, it is easy to cause the fusion phenomenon of the phenolic plastic during the crushing process

Embodiment 1

[0022] as attached figure 1 To attach Figure 5 Shown:

[0023] The present invention is a pulverizer for plastic production, which comprises a motor 1, a dust cover 2, a pulverizer body 3, a feed port 4, and a discharge port 5, and the output end of the motor 1 is installed inside the dust cover 2, so that The upper end of the dustproof cover 2 is installed outside the pulverizer body 3, the upper end of the pulverizer body 3 is fixedly installed with a feed port 4 and communicates with each other, and the lower end of the pulverizer body 3 is embedded with a discharge port 5 to communicate with each other. It includes a casing 31, a toggle mechanism 32, a crushing mechanism 33, and a cylinder wall 34. A toggle mechanism 32 is fixedly installed on the upper end of the casing 31. The toggle mechanism 32 is located at the lower end of the feeding port 4, and the crushing mechanism 33 is fixed. Installed at the lower end of the shell 31, the crushing mechanism 33 rotates synch...

Embodiment 2

[0030] as attached Figure 6 To attach Figure 7 Shown:

[0031] Wherein, the crushing mechanism 33 includes a rotating shaft 331, a moving knife 332, and a pendulum 333. The rotating shaft 331 rotates synchronously with the output end of the motor 1 through the belt provided inside the dust cover 2. The rotating shaft 331 It runs through the inside of the moving knife 332 and rotates synchronously. The outer wall of the moving knife 332 is fixed to the lower end of the pendulum 333. There are sixteen pendulums 333 in total, and four of them form a group. In four directions, it is beneficial to crush fine phenolic plastics.

[0032]Wherein, the pendulum 333 includes a swing rod 33a, a spring 33b, a knife edge 33c, and a hammer body 33d. 33b is fixed to the upper end of the swing rod 33a, and the upper end of the swing rod 33a is installed inside the hammer body 33d with clearance fit. The blade 33c is fixedly installed on the outside of the hammer body 33d. The inclination...

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.
