[0034] The specific implementation process of the present utility model is as follows: the staff first connects the cover plate 205 to the gas purifier 5 through the exhaust pipe 204, turns on the gas purifier 5, and adds the raw materials into the interior of the barrel assembly 1 through the feeding port 201 by rotating the baffle 203. After the appropriate amount is reached, the baffle 203 is closed to make the feeding port 201 in a closed state, and the heating layer 103 of the barrel assembly 1 begins to heat up. The first motor 604 rotates at a low speed to drive the rotating column 601 to rotate. The rotating column 601 drives the first plate 602 and the second plate 603 to rotate. The first plate 602 scrapes the inner wall 104, and the second plate 603 moves the internal plastic particles to avoid uneven heating. During the heating process, the melted plastic will produce harmful gases, which will be extracted and filtered by the gas purifier 5 to evolve.

At the same time, the setting of the second plate 603 helps to evenly heat the plastic particles and reduce the problem of material adhesion. During cleaning, the first motor 604 rotates continuously to scrape the residual plastic on the inner wall 104 onto the first plate 602, which simplifies the cleaning process and improves production efficiency;

[0035] After being heated to a specified temperature, the internal raw materials are melted, the valve body 701 is opened, and the raw materials flow into the first pump body 702. The first pump body 702 pumps the raw materials to the discharge port 703, where they are further processed by the staff. Through the arrangement of the barrel assembly 1 and other structures, the barrel assembly 1 includes an outer wall 101, an insulation layer 102, a heating layer 103 and an inner wall 104. Such a structural design helps to reduce heat loss, improve heating efficiency, and thus reduce energy consumption.

[0036] When all the raw materials are melted, the first motor 604 rotates continuously to clean the residual plastic on the inner wall 104 and scrape it all onto the first plate 602. The heating plate cools down at the same time, and the residual plastic is collected on the first plate 602. The interior can be cleaned by simply taking out the first plate 602 and the second plate 603 and scraping off the residual plastic.
