It heats the material to a plastic state, then extrude the material through a mold through a series of spirals or plungers, and then discharges the molded material through the barrel to produce a product of the desired shape. When the barrel discharges the molded material, dust carried on the outside of the material is likely to remain and adhere to the inner wall of the barrel, requiring manual cleaning using a cleaning brush on a regular basis.

The above-mentioned prior art proposes to use the spray mechanism to flush the inner wall of the barrel, thereby achieving the effect of automatic cleaning.

[0004] In the above-mentioned prior art, a spray mechanism is used to spray water on the inner side of the barrel, so that the dust and the like attached to the inner wall of the barrel are washed away by the flushing of the water flow, thereby achieving an automatic cleaning effect. Although this flushing method is relatively convenient, the kinetic energy of the water flow will be lost after being sprayed and hitting the inner wall of the barrel, thereby reducing its flushing force and making the cleaning effect of other parts of the barrel poor.

Before use, water is injected into the water storage tank 6 through the water inlet 61 for storage to facilitate subsequent use.

[0024] like Figure 1 and Figure 3As shown, a spraying assembly is fixedly connected to the lower side of both ends of the water tank 6, and the spraying assembly includes a water pump 7 fixedly connected to the lower side of the middle end of the water tank 6, a water pipe 71 is fixedly connected to the lower end of the water pump 7, and a water spray port 72 is fixedly connected to the lower end of the water pipe 71, and the lower end of the water spray port 72 is arranged to penetrate the machine barrel 1. After the water pump 7 is started, the water in the water tank 6 is pumped out, and then the water is sprayed into the inside of the machine barrel 1 through the water pipe 71 and the water spray port 72, so as to facilitate the water in the water tank 6 to be pumped out and sprayed into the machine barrel 1, thereby assisting the cleaning assembly and the scraping assembly to clean the inside of the machine barrel 1 and the rotating barrel 2.

[0025] like Figure 1 As shown, the rotating assembly includes a rotating cylinder 2 rotatably connected to the inner side of the middle end of the machine barrel 1, and a tooth plate 21 is fixedly connected to the outer side of one end of the rotating cylinder 2. The power assembly drives the tooth plate 21 to operate by engaging with the tooth plate 21, so that the tooth plate 21 drives the rotating cylinder 2 to rotate, which makes it easier for the rotating cylinder 2 to drive the cleaning assembly to rotate.

[0026] like Figure 1 As shown, the power assembly includes a fixed plate 3 fixedly connected to the upper side of one end of the machine barrel 1, and a motor 31 is fixedly connected to the outer side of one end of the fixed plate 3, and a gear 32 is fixedly connected to the output shaft of the motor 31, and the outer side of one end of the gear 32 is meshed with the toothed plate 21. The motor 31 and the water pump 7 are started. After the motor 31 is started, the output shaft drives the gear 32 to rotate. After the gear 32 rotates, the toothed plate 21 meshes with the toothed plate 21 to drive the rotating barrel 2 to rotate, so as to provide power output, thereby driving the toothed plate 21 to operate.

When the inner wall of the machine barrel 1 needs to be cleaned, start the motor 31 and the water pump 7. After the motor 31 is started, the output shaft drives the gear 32 to rotate. After the gear 32 rotates, the gear plate 21 drives the rotating drum 2 to rotate through the engagement with the toothed plate 21. After the rotating drum 2 rotates, it simultaneously drives the first fixed frame 4 and the first cleaning brush 41 to rotate, so that the first cleaning brush 41 cleans the inner side of both ends of the machine barrel 1. At the same time, when the rotating drum 2 rotates, the inner wall of the rotating drum 2 is cleaned by the second cleaning brush 51. After the water pump 7 is started, the water in the water tank 6 is pumped out, and then the water is sprayed into the inside of the machine barrel 1 through the water pipe 71 and the water spray port 72. The sprayed water cooperates with the first cleaning brush 41 and the second cleaning brush 51 to clean the inner walls of the machine barrel 1 and the rotating drum 2.
