[0027] Combination Figures 1 to 3 As shown, the volume reduction machine of the present invention is schematically shown, including a pusher assembly and two extrusion assemblies.

[0028] The pushing assembly includes a material distribution box 10 and two pushing screws 20 located in the material distribution box 10 and arranged in parallel. The material distribution box 10 is a hollow structure. A material distribution component 11 located between the two pushing screws 20 is provided in the material distribution box 10. A feed port 12 and two discharge ports are provided on the material distribution box 10. The feed port 12 passes through the inside and outside of the material distribution box 10, and the discharge ports pass through the inside and outside of the material distribution box 10. The feed port 12 is arranged opposite to the material distribution component 11, one discharge port is located on the axial direction of one pushing screw 20, and the discharge port is located on the axial direction of the corresponding pushing screw 20. The foam material enters the material distribution box 10 from the feed port 12, and the material distribution component 11 distributes the foam material to the two pushing screws 20. The pushing screws 20 rotate to crush the foam material and continuously transport the foam material to the discharge port.

[0029] The extrusion assembly includes an extrusion groove 30 with a U-shaped cross section and an extrusion component 40 located at the opening of the extrusion groove 30. An extrusion cavity 31 with two ends intersecting each other is formed between the extrusion groove 30 and the extrusion component 40, that is, the extrusion cavity 31 is a tubular structure, and the extrusion cavity 31 has a feed end and a discharge end. The extrusion component 40 is rotatably connected to the extrusion groove 30, and the rotating shaft between the extrusion component 40 and the extrusion groove 30 is located at the feed end. Two extrusion assemblies are arranged in parallel, one extrusion assembly corresponds to one discharge port, and the feed end of the extrusion assembly is connected to the corresponding discharge port. The push screw 20 continuously transports the crushed foam material to the extrusion cavity 31, and the extrusion component 40 rotates relative to the extrusion groove 30 to extrude and compact the foam material.

[0030] The material distribution component 11 has two guide slopes 111 arranged opposite to each other, so that the cross section of the material distribution component 11 is triangular. The foam material dropped from the feed port 12 moves to one of the push screws 20 under the guidance of the guide slopes 111 to achieve material distribution.

[0031] The pusher assembly further includes a drive device 50 disposed on the material distribution box 10, and the drive device 50 is connected to the pusher screw 20. Specifically, there are two drive devices 50, each of which is connected to one pusher screw 20, so as to realize independent driving of the two pusher screws 20. The drive device 50 is preferably a connected drive motor and a reducer, and the reducer is connected to the pusher screw 20.

[0032] The extrusion assembly also includes a connecting box 60 having a connecting cavity 61, the two ends of which are interconnected, and the two ends of the connecting cavity 61 are respectively connected to the feed end and the discharge port. The connecting cavity 61 serves as a buffer space to collect the crushed foam material and to make the outer shape structure of the crushed foam material match the internal structure of the connecting cavity 61.

[0033] One end of the pushing screw 20 extends into the connecting cavity 61 to push the crushed foam material into the connecting cavity 61. Figure 3, the pushing screw 20 is provided with a first spiral piece 21 and a second spiral piece 22 which are spirally arranged around its axis, the first spiral piece 21 and the second spiral piece 22 are arranged in parallel, the first spiral piece 21 extends from one end of the pushing screw 20 to the other end of the pushing screw 20, and the second spiral piece 22 is located in the connecting cavity 61. In the connecting cavity 61, the first spiral piece 21 and the second spiral piece 22 jointly push the foam material in the connecting cavity 61 to give the foam material a greater driving force, so that the foam material can be squeezed more tightly in the extrusion cavity 31. Specifically, the thickness of the first spiral piece 21 located in the connecting cavity 61 is greater than the thickness of the first spiral piece 21 located in the distribution box 10, and the thickness of the second spiral piece 22 is consistent with the thickness of the first spiral piece 21 located in the connecting cavity 61, so as to improve the strength of the first spiral piece 21 and the second spiral piece 22 located in the connecting cavity 61, so that the first spiral piece 21 and the second spiral piece 22 located in the connecting cavity 61 can withstand a greater extrusion force.

[0034] In order to drive the extrusion component 40 to rotate relative to the extrusion groove 30, the extrusion assembly also includes a hydraulic cylinder 41, and the two ends of the hydraulic cylinder 41 are respectively connected to the extrusion groove 30 and the extrusion component 40. When the hydraulic cylinder 41 is extended, one end of the extrusion component 40 moves toward the extrusion groove 30 to extrude the foam material. When the hydraulic cylinder 41 is contracted, one end of the extrusion component 40 moves in a direction away from the extrusion groove 30, so as to prevent the extrusion component 40 from forming resistance to the extruded foam material, thereby preventing the accumulated foam material from being removed from the extrusion chamber 31.

[0035] Preferably, the extrusion assembly also includes a mounting frame 70 connected to the extrusion groove 30, the mounting frame 70 is arranged opposite to the opening of the extrusion groove 30, one end of the hydraulic cylinder 41 is connected to the mounting frame 70, and the other end of the hydraulic cylinder 41 is connected to the extrusion component 40, and the mounting frame 70 is used to install and fix the hydraulic cylinder 41.

[0036] Compared with the prior art, the beneficial effects of the present invention are: the distribution box 10 distributes the foam material to the two pushing screws 20 through the distribution component 11, the pushing screws 20 continuously crush the foam material and convey it to the extrusion chamber 31, and the extrusion component 40 extrude and compact the foam material in the extrusion groove 30, thereby realizing automatic and continuous crushing and extrusion of the foam material.
