[0032] The hot melt unit includes a hot melt chamber 41, which is similar in structure to the drying chamber 35 and is cylindrical in shape. The hot melt chamber 41 and the drying chamber 35 are in a connected state. The spiral rod 12 can transport the dried foam block to the hot melt chamber 41, and the spiral rod 12 penetrates the hot melt chamber 41 horizontally. A stirring paddle is provided on the spiral rod 12 at the hot melt chamber 41. When the spiral rod 12 rotates, the stirring paddle can continuously stir the hot melted foam block to prevent it from sticking together to form a block, and to make the foam slurry evenly heated. A heating wire is installed on the inner wall of the hot melt chamber 41, and the heating wire can quickly generate high temperature to heat and melt the foam block into a viscous state with fluidity. A square upper opening is provided at the upper end of the hot melt chamber 41, and a slurry outlet is provided at the lower end of the hot melt chamber 41. A hot slurry outlet round tube 42 is connected to the slurry outlet, and the hot melted foam slurry can flow into the molding mold through the hot slurry outlet round tube 42.

[0033] The molding mold includes a mold base 43, which is fixedly connected to the frame 11. A lower mold base 45 is arranged on the mold base 43, and an upper mold base 44 is arranged above the lower mold base 45. The upper mold base 44 corresponds to the lower mold base 45. The upper mold base 44 can move vertically and can be connected with the lower mold base 45. A circular through hole is arranged in the middle position of the upper mold base 44, and the circular through hole is connected with the pulp outlet circular tube 42.

[0034] In the embodiment in which the upper mold base 44 moves vertically, the slurry discharge circular tube 42 is a retractable bellows.

[0035] Specifically, the vertical movement of the upper die seat 44 is realized by an indirect reciprocating mechanism arranged at one end of the frame 11. The indirect reciprocating mechanism includes a rectangular plate 51, which is located at one end of the frame 11 and is vertically fixedly connected to the frame 11. Two linear slide grooves are arranged on both sides of the plate 51. A slide plate 52 is connected between the two slide grooves. The slide plate 52 can move vertically along the slide groove.

The gear set in the gear box is connected with a transmission shaft, and the transmission shaft is fixedly connected to the large gear 53. A convex tooth segment is provided on the large gear 53, and the large gear 53 meshes with the rack on the skateboard 52.

When the convex tooth on the large gear 53 rotates to the other side of the skateboard 52 and meshes with the rack, the reverse skateboard 52 can be driven to move.

[0036] Two parallel fixing rods 54 are arranged at the upper end of the slide plate 52. The fixing rods 54 and the slide plate 52 are perpendicular to each other. A cross bar 55 is connected between the two fixing rods 54. The cross bar 55 is located above the hot melt chamber 41. A vertical rod 56 is vertically arranged in the middle of the cross bar 55. The vertical rod 56 extends into the upper opening of the hot melt chamber 41, and an extrusion block 57 is arranged on the vertical rod 56. When the slide plate 52 moves vertically, it can drive the extrusion block 57 to move vertically in the hot melt chamber 41. The extrusion block 57 moves vertically to squeeze the foam slurry out of the hot melt chamber 41. The middle of the extrusion block 57 is an arched channel to prevent the extrusion block 57 from interfering with the rotation of the spiral rod 12 when it moves vertically. Die base ears 46 are arranged on both sides of the upper die base 44. The die base ears 46 are fixedly connected with a stabilizing rod 58. The stabilizing rod 58 is vertically fixedly connected to the slide plate 52. When the slide plate 52 drives the compression block to extrude the foam slurry, it can drive the upper die base 44 to move vertically.

[0037] Working principle: The operator puts the waste foam into the cutting bin 21 through the feed hopper 23, starts the motor, drives the rotating shaft 24 to rotate through the transmission chain 15, and the rotating blade 25 on the rotating shaft 24 can cut the foam into small pieces. The foam blocks fall into the plate shell 31 through the screen 28 and the square funnel 29, and then the foam blocks are cleaned by the high-pressure nozzle 32, and the foam blocks are transported to the drying chamber 35 for drying through the rotation of the screw rod 12. The dried foam blocks are then transported to the hot melt chamber 41 through the screw rod 12, and the foam blocks are melted into foam pulp. The foam pulp can flow into the forming mold from the pulp outlet of the hot melt chamber 41, and form a product under the extrusion of the upper mold base 44 and the lower mold base 45. In this process, the vertical movement of the upper mold base 44 and the extrusion of the foam pulp by the extrusion block 57 are completed through the indirect reciprocating mechanism.
