[0003] Currently, in order to improve the uniformity of heating during the use of common plastic material hot melting machines in the prior art, a stirring device is often added to stir the plastic material, and at the same time, heating sheets provided on the inner wall are used to heat the material. During the heating and stirring processes, the surface areas of the stirring blades and the heating sheets in contact with the plastic material are relatively large, resulting in a large amount of material adhering to their surfaces. Moreover, there is a certain amount of moisture adhering to the surface of some materials. These problems will all lead to uneven heating of the materials, resulting in a decline in product quality, and it is inconvenient to clean the materials adhering to the surfaces of the stirring blades and the heating sheets.

Two adjustable cleaning components 105 are sleeved on the hot-melting component 103; The hot-melting auxiliary mechanism 200 includes a driving component 201. A multi-sided sleeve 203 is connected in the driving component 201. The multi-sided sleeve 203 is rotatably installed on the upper cover 104 through a bearing. The bottom end of the multi-sided sleeve 203 is connected to the hot-melting component 103. A plurality of locking components 207 are arranged above the multi-sided sleeve 203. A multi-sided cylinder 210 is slidably connected in the multi-sided sleeve 203. An adjustable conveying component 202 is arranged in the multi-sided cylinder 210. The bottom end of the adjustable conveying component 202 is connected to a stirring component 206. Two rope winding components 208 are arranged on the stirring component 206. The two rope winding components 208 penetrate upward through the multi-sided cylinder 210 and are connected to the top of a guiding component 209. The top of the guiding component 209 is connected to the adjustable conveying component 202. The top end of the adjustable conveying component 202 is connected to a hot air device 204.

[0027] In this embodiment: The driving component 201 drives the multi-sided sleeve 203 to drive the hot-melting component 103 to rotate and stir the materials. At the same time, the multi-sided sleeve 203 drives the adjustable conveying component 202 to move up and down through the multi-sided cylinder 210 to adjust the position of the stirring component 206, so that the up and down movement of the stirring component 206 can cooperate with the rope winding component 208 to drive the stirring component 206 to rotate and stir, enabling the stirring component 206 to perform stirring operations up and down. During the stirring process, hot air is conveyed through the hot air device 204, so that hot air is conveyed during the stirring process of the stirring component 206 for preheating to remove the moisture on the materials. At the same time, the movement of the adjustable conveying component 202 can reduce the internal cavity, and then the hot air can be pressurized and discharged, increasing the jet intensity of the hot air, enabling it to cooperate with the stirring of the stirring component 206 and the hot-melting component 103, which can greatly improve the effect of preheating and drying the moisture of the materials, and can also improve the mixing effect of the materials, thereby improving the hot-melting efficiency of the materials.

[0028] Working principle: When performing the hot-melting operation of the materials, hot air is conveyed through the hot air device 204 into the hollow screw 2021, and enters the threaded cylinder 2022 along the hollow screw 2021, enters the pipeline 2064 and the flat pipe 2061 through the threaded cylinder 2022, and then hot air is sprayed out from the nozzle 2062 through the hollow blade 2063 to preheat and dry the moisture of the materials inside the hot-melting tank 101; Then, control the motor 2011 to drive the first gear 2013 to transmit power with the second gear 2014. The second gear 2014 drives the multi-sided sleeve 203 to rotate. The multi-sided sleeve 203 drives the top plate 1031 to rotate. The top plate 1031 drives the scraper 1032 and the heater 1033 to rotate, so that the scraper 1032 agitates the material to flow. At the same time, the heater 1033 operates to perform hot melting operation on the material. When the multi-sided sleeve 203 rotates, the multi-sided sleeve 203 also drives the multi-sided cylinder 210 to rotate, so that the multi-sided cylinder 210 drives the stirring assembly 206 to perform a revolution motion, and the multi-sided cylinder 210 drives the threaded cylinder 2022 to be in threaded transmission with the hollow screw 2021, so that the threaded cylinder 2022 moves upward along the hollow screw 2021. The threaded cylinder 2022 drives the multi-sided cylinder 210 to move upward. The multi-sided cylinder 210 drives the stirring assembly 206 and the adjustable cleaning assembly 105 to move upward. The scraping blade frame 1051 and the scraping blade holder 1053 can move upward to clean the heater 1033 and the scraper 1032; Moreover, as the stirring assembly 206 moves upward, the rope 2081 loosens upward. The torsion of the torsion spring 2083 can drive the rope reel 2082 to wind up the rope 2081, so that the rope reel 2082 drives the flat tube 2061 to rotate. The flat tube 2061 drives the hollow blade 2063 to rotate. The hollow blade 2063 moves upward and agitates the material to flow. When the torsion of the torsion spring 2083 is completely released, at this time, the hollow blade 2063 and the flat tube 2061 are in a vertical state. At this time, the hollow blade 2063 and the flat tube 2061 enter the cleaning scraping frame 1022. The cleaning scraping frame 1022 can clean the hollow blade 2063 and the flat tube 2061 to reduce material adhesion. Then, reverse the motor 2011, so that the threaded cylinder 2022 drives the multi-sided cylinder 210 to move downward. At this time, after the rope 2081 is stretched, it can drive the rope reel 2082 to rotate, and then keep the stirring assembly 206 to perform a downward stirring operation to make the material perform a uniform hot melting processing operation; When it is necessary to open the upper cover 104 for maintenance, remove the bolts of the upper cover 104, and then screw the fixing bolt 2071 into the locking hole of the multi-sided cylinder 210. At this time, the driving assembly 201 drives the multi-sided sleeve 203 and the multi-sided cylinder 210 to rotate, so that the threaded cylinder 2022 moves upward. The driving assembly 201 can drive the upper cover 104 to move upward. When the scraper 1032, the heater 1033 and the stirring assembly 206 move upward out of the hot melting tank 101, it is convenient to perform maintenance operations; Secondly, when storing this device, remove the bolts on the adjusting frame 205 from the guide rail 211. At the same time, the multi-sided sleeve 203 is connected to the multi-sided cylinder 210 through the locking assembly 207. Then, reverse the driving assembly 201, so that the driving assembly 201 drives the multi-sided sleeve 203 to drive the multi-sided cylinder 210 to rotate. The threaded cylinder 2022 is in transmission with the hollow screw 2021, so that the hollow screw 2021 can move downward and be received into the threaded cylinder 2022, thereby realizing the storage of the hollow screw 2021.
