[0022] The effect achieved by the entire embodiment 1 is that the foaming profile can be moved by the operation of the driving structure 3. When one end of the foaming profile enters the co-extrusion mold 5, the stirring anti-blocking structure 14 operates to allow the melted and mixed materials inside the chassis 10 to enter the co-extrusion mold 5. Due to the material problem of the foaming profile, the high-temperature material will also melt the top of the foaming profile to a certain extent, so that the material is mixed with the foaming profile and finally moved out from the discharge pipe 6. The refrigerator 17 will cool and shape it when it is moved out.

[0023] Embodiment 2, as Figure 1-4As shown, the driving structure (3) includes two first motors (301) arranged at one end of the machine bin (2), the output end of the first motor (301) passes through one side of the machine bin (2) and is fixed with a first driving roller (302), the first driving roller (302) is connected to a second driving roller (303) through a transmission belt (304), and the stirring anti-blocking structure (14) includes a stabilizing plate (15) fixed on the inner wall of the machine box (10), and the top of the stabilizing plate (15) is installed with a first The second motor (1401) has an output end that passes through the bottom end of the stabilizing plate (15) and is fixed with a stirring shaft (1402). A plurality of stirring blades (1403) that match the internal space of the chassis (10) are fixed on the outer wall of the stirring shaft (1402). An auger (1404) is fixed at the bottom end of the stirring shaft (1402). The auger (1404) is arranged in the connecting pipe (11). The first driving roller (302) and the second driving roller (30 3) are both arranged in the machine chamber (2), and the first driving roller (302) and the second driving roller (303) are both rotatably connected to the machine chamber (2), a support plate (4) is fixed on the outer wall of the machine chamber (2), the first motor (301) is installed on the top of the support plate (4), both ends of the co-extrusion die (5) are fixed with first mounting plates (7), the two first mounting plates (7) are fixed to the main board (1) by first bolts (8), and both ends of the connecting pipe (11) are fixed with second A mounting plate (12), the two second mounting plates (12) are fixed to the co-extrusion die (5) by second bolts (13), third mounting plates (18) are fixed to both ends of the refrigerator (17), the two third mounting plates (18) are fixed to the discharge pipe (6) by third bolts (19), a bracket (9) is fixed to the top of the main board (1), the chassis (10) is installed in the bracket (9), and legs (24) are fixed to the four corners of the bottom end of the main board (1).

[0024] The effect achieved by the entire embodiment 2 is that the operation of the two first motors 301 can drive the two first driving rollers 302 to rotate, and the cooperation of the two second driving rollers 303 can drive the two transmission belts 304, so that the foaming profile between the two transmission belts 304 can move following the transmission of the transmission belts 304, and the operation of the second motor 1401 can drive the stirring shaft 1402 to rotate, thereby driving the stirring blade 1403 to rotate, so that it can fully stir and mix the materials in the chassis 10 and perform color matching. When the stirring shaft 1402 rotates, it will drive the auger 1 404 rotates to guide the melted material in the chassis 10 to enter the co-extrusion mold 5. The first mounting plate 7 and the first bolt 8 are arranged so that the co-extrusion mold 5 can be disassembled to facilitate its replacement. The second mounting plate 12 and the second bolt 13 are arranged so that the connecting pipe 11 can be stably docked with the co-extrusion mold 5 to prevent the docking tilt. The third mounting plate 18 and the third bolt 19 are arranged so that the refrigerator 17 can be disassembled at any time to avoid the problem that when the co-extrusion mold 5 is replaced, the refrigerator 17 must also be replaced, which is more practical.

[0025] Working principle: When the device is used, the operation of the two first motors 301 can drive the two first drive rollers 302 to rotate, and the cooperation of the two second drive rollers 303 can drive the two transmission belts 304, so that the foaming profile between the two transmission belts 304 can move following the transmission of the transmission belts 304. When one end of the foaming profile enters the co-extrusion mold 5, the operation of the second motor 1401 can drive the stirring shaft 1402 to rotate, thereby driving the stirring blade 1403 to rotate, so that it can rotate the inside of the chassis 10. The materials are fully stirred and mixed, and the color is adjusted. The material in the chassis 10 is melted and heated by the operation of the heating plate 16. When the stirring shaft 1402 rotates, the auger 1404 is driven to rotate, so that the melted material in the chassis 10 is guided to enter the co-extrusion mold 5. Due to the material problem of the foamed profile, the high-temperature material will cause the top of the foamed profile to melt to a certain extent, so that the material is mixed with the foamed profile and finally moved out from the discharge pipe 6. The refrigerator 17 will cool and shape it when it is moved out.

[0026] The wiring diagram of the first motor 301, the second motor 1401 and the heating plate 16 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the first motor 301, the second motor 1401 and the heating plate 16 are not explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
