[0036] In use of the extrusion device, first open the segmented heating mechanism 6 on the extrusion pipe 2, then pour the particles into the feeding hopper 12, under the action of the auxiliary continuous feeding mechanism 7, the particles enter the extrusion pipe 2, at the same time, the extrusion motor 3 drives the support rod 4, the support rod 4 drives the extrusion auger 5, the extrusion auger 5 drives the particles to move in the extrusion pipe 2, when the particles pass through the segmented heating mechanism 6 on the extrusion pipe 2, the segmented heating mechanism 6 melts the particles, then continues to be pushed by the extrusion auger 5, so that the melted particles are extruded from the extrusion head 8 into a sheet, the traction roller group 10 supports and guides the just-formed sheet, at the same time, the water cooling device 9 circulates the extrusion head 8 to ensure that the sheet is extruded from the extrusion head 8, then according to the actual length, the cutting device 11 cuts the sheet, when the particles in the feeding hopper 12 are almost out, the auxiliary continuous feeding mechanism 7 sends a reminder, then the staff replenishes in time, by setting the segmented heating mechanism 6 on the extrusion pipe 2, the particles can be uniformly mixed and fully melted when passing through the segmented heating mechanism 6 on the extrusion pipe 2, so as to improve the product quality stability and shorten the production cycle.

[0037] With reference to Figure 1 , Figure 2 and Figure 4 , the segmented heating mechanism 6 comprises a heating sleeve 61 sleeved on the extrusion pipe 2, three groups of two-symmetric support rings 63 are arranged between the heating sleeve 61 and the extrusion pipe 2, the support rings 63 are fixedly connected with the extrusion pipe 2 and the heating sleeve 61, a plurality of heating rods 62 are fixed between the two support rings 63 and circumferentially distributed, three temperature sensors 64 are fixed on the heating sleeve 61, and the temperature sensors 64 penetrate through the heating sleeve 61.

One side of the feeding hopper 12 is provided with a conversion driving assembly 74, and the feeding hopper 12 is provided with a triggering assembly 75.

[0042] In addition, the conversion driving assembly 74 comprises a support frame 741 fixed on one side of the feeding hopper 12, and a driving motor 742 fixed on the support frame 741. The output end of the driving motor 742 is fixed with a gear one 743, and the gear one 743 is rotatably connected with the support frame 741.

The traction roller group 10 supports and guides the just-formed sheet, and the water cooling device 9 circulates cooling for the extrusion head 8 to ensure the extrusion and shaping of the sheet from the extrusion head 8.
