The lower end of the material guiding cylinder 7 respectively penetrates the upper concave plate 3 and the upper filter plate 31, and the lower end of the material guiding cylinder 7 is located in the upper ring opening of the annular shell frame 4. Figure 2As shown, the upper and lower concave discs 3 respectively block the upper and lower ring openings of the annular shell cover 2, and the space between the upper and lower filter discs 31 serves as a cleaning chamber for heat shrinkage waste; wherein, the lower end of the guide cylinder 7 is rotatably connected to the upper ring opening of the annular shell frame 4, which has a relative sealing effect, so that the heat shrinkage waste guided out from the lower end of the guide cylinder 7 can smoothly fall onto the outer wall of the lower end of the pipe 2 33; wherein, the outer shell of the lower end of the pipe 2 33 is a conical structure, so that the heat shrinkage waste that falls into it can be quickly dispersed into the cleaning chamber, and the heat shrinkage waste is cleaned by the cleaning mechanism 5; wherein, during the cleaning process, cold gas is introduced into the pipe 2 33 through the pipe 3 34. On the one hand, the cold gas flows out through the lower filter disc 31, which can play the effect of blowing the heat shrinkage waste, so that the heat shrinkage waste can fully roll between the upper and lower filter discs 31, thereby improving the activity of the heat shrinkage waste. , so that the cleaning mechanism 5 can clean the heat shrinkable waste more fully and improve the cleaning quality of the heat shrinkable waste. On the other hand, the cold gas can solidify the heat shrinkable waste, which is beneficial for making the heat shrinkable waste in a harder structural state, so that the cleaning structure 5 can better contact, clean and remove the dust on the surface of the heat shrinkable waste. The cold gas that penetrates the heat shrinkable waste and mixes with the dust enters the pipe 1 32 through the upper filter plate 31 and is discharged. Among them, the purity of the discharged cold gas can be tested to timely understand the cleaning status of the heat shrinkable waste in the cleaning chamber. When the cleaning process is completed, the side space of the cleaning chamber is opened by the material control mechanism 6, and the operation of the cleaning mechanism 5 is coordinated to make the heat shrinkable waste that has been cleaned flow to the blanking port 21 and fall into the melting chamber 12 through the blanking port 21 for melting process.
