[0048] Please refer to Figures 1 to 7The embodiment provides a cold pressing equipment for recycling polyethylene foam, and the scheme points include: a first shell 1, a compression and pushing assembly 2, a crushing assembly 3 and a softening assembly 4. The first shell 1 includes a first end 12 and a second end 13. The first end 12 is provided with a mounting hole 121. The second end 13 is provided with a discharging channel 11. The compression and pushing assembly 2 includes a pushing assembly 21 and a driving assembly 22. The pushing assembly 21 is rotatably arranged in the first shell 1. One end of the pushing assembly 21 is arranged to pass through the mounting hole 121 and is drivingly connected with the driving assembly 22. The driving assembly 22 drives the pushing assembly 21 to rotate, so that the pushing assembly 21 extrudes the foam in the first shell 1 through the discharging channel 11. The crushing assembly 3 is arranged on the first shell 1 and is provided with a feeding port 32. The bottom of the crushing assembly 3 is provided with a discharging port 31. The discharging port 31 is communicated with the inside of the first shell 1. The crushing assembly 3 is used for crushing the foam into foam crumbs, so that the foam crumbs enter the first shell 1 through the discharging port 31. The softening assembly 4 includes a ventilation pipeline 41. The ventilation pipeline 41 is communicated with the inside of the first shell 1 and / or the crushing assembly 3, so that hot air is blown into the first shell 1 and / or the crushing assembly 3 through the ventilation pipeline 41, so that the foam in the first shell 1 and / or the crushing assembly 3 is softened.

[0049] The operator first puts the foam into the crushing assembly 3 through the feeding port 32, so that the foam is crushed into foam crumbs by the crushing assembly 3. The crushed foam is more convenient for subsequent compression, hot melting and other processing operations, and the efficiency of the compressed and hot melted foam can be effectively improved. The crushed foam crumbs enter the first shell 1 through the discharging port 31. The pushing assembly 21 arranged on the first shell 1 is drivingly connected with the driving assembly 22. The driving assembly 22 drives the pushing assembly 21 to rotate. The pushing assembly 21 extrudes the foam crumbs in the first shell 1 along the direction of the discharging channel 11. In this way, the volume of the foam itself is greatly reduced, which is convenient for subsequent storage and packaging and transportation of the recycled foam. In addition, the softening assembly 4 is arranged. The softening assembly 4 can blow hot air into the first shell 1 and / or the crushing assembly 3. The softening assembly 4 can soften the foam. The softened foam is convenient for subsequent compression molding, which is beneficial to further reducing the volume of the foam. The volume of the foam can be greatly reduced by the above scheme, and the occupied space is small, so that the subsequent recycling, transportation and storage costs are reduced, and the factory benefit is improved.

[0050] Further, please refer to Figures 2 to 5The extrusion assembly 16 is arranged at the discharge channel 11, and the extrusion assembly 16 comprises at least one frame body 161 and a pressing plate 163. A through hole 15 is arranged at the top of the discharge channel 11. The frame body 161 is arranged above the discharge channel 11. A plurality of frame bodies 161 are arranged with telescopic members 162. The telescopic direction of the telescopic members 162 is substantially perpendicular to the length direction of the discharge channel 11. The telescopic ends of the telescopic members 162 are connected with the pressing plate 163. The pressing plate 163 is used for pressing the foamed cotton extruded from the discharge channel 11. The pressing plate 163 is arranged in correspondence with the through hole 15, so as to adjust the distance between the pressing plate 163 and the through hole 15 through the telescopic members 162.

[0051] The extrusion assembly 16 can further compress the foamed cotton extruded from the discharge channel 11. After the foamed cotton is preliminarily compressed and extruded by the compression and pushing assembly 2, the density of the foamed cotton is improved to a certain extent. The foamed cotton is pressed by the pressing plate 163 through the through hole 15, so as to further reduce the volume of the foamed cotton and further increase the density of the foamed cotton. The telescopic ends of the telescopic members 162 can adjust the height of the pressing plate 163, so as to provide different compression effects on the foamed cotton extruded from the discharge channel 11.

This spiral compression mode can avoid the situation that the local pressure is too large or too small, and ensures that the foam cotton is stably compressed into a relatively dense state. The rotation of the Jiaolong blade 212 can smoothly push the compressed foam cotton through the discharge channel 11. The Jiaolong blade 212 can generate an axial thrust, so that the foam cotton continuously moves towards the extension direction of the discharge channel 11.

The first spiral blade 212a is arranged on the outer peripheral surface of the first shaft rod 211a, and the second spiral blade 212b is arranged on the outer peripheral surface of the second shaft rod 211b. When the second shaft rod 211b is mounted to the first shaft rod 211a, the second spiral blade 212b and the first spiral blade 212a combine to form the Jiaolong blade 212.

During long-time operation of the equipment, the pushing and pressing assembly 21 may be worn due to friction with the foam cotton, and the part close to the discharge port 31 is more prone to damage. The detachable structure facilitates the user to replace the second shaft rod 211b and the second spiral blade 212b thereon alone, without the need to replace the entire central shaft 211, thereby reducing the maintenance cost of the equipment.
