[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Referring to Figures 1 - 6 , the unloading mechanism of this paper tray forming machine includes an upper die assembly 1 and a material receiving device. The upper die assembly 1 is located above the material receiving device. The material receiving device includes a driving assembly 2, a lifting assembly 3, and a material receiving table 4. The driving assembly 2 is drivingly connected to the lifting assembly 3. The material receiving table 4 is fixed on the lifting assembly 3. The driving assembly 2 drives the material receiving table 4 to move upward to a specified position through the lifting assembly 3 to reduce the distance between the upper die assembly 1 and the material receiving table 4.

[0024] After the material receiving table 4 moves upward to the specified position, the driving assembly 2 drives the material receiving table 4 to descend step by step through the lifting assembly 3 so that a constant distance is maintained between the material receiving table 4 and the upper die assembly 1.

[0025] The paper tray forming machine includes a machine body 5. A moving device, a forming station 6, and a unloading station 7 are provided on the machine body 5. The moving device is drivingly connected to the upper die assembly 1. A lower die assembly 21 is provided at the forming station 6. The material receiving device is located at the unloading station 7. The moving device drives the upper die assembly 1 to move to the forming station 6 or the unloading station 7 to form products or unload products.

[0026] After the paper tray product is formed at the forming station 6, the moving device drives the upper die assembly 1 to move from the forming station 6 to the unloading station 7. The driving assembly 2 drives the material receiving table 4 to move upward to a specified position through the lifting assembly 3 (at this time, there is generally no paper tray finished product placed on the material receiving table 4). The upper die assembly 1 unloads the paper tray finished product onto the material receiving table 4. Then, because there is a paper tray finished product on the material receiving table 4, to prevent the paper tray finished product on the material receiving table 4 from piling up and hindering unloading, the material receiving table 4 descends a specified height and waits for the next paper tray product to be formed. Then the upper die assembly 1 moves from the forming station 6 to the unloading station 7 for the next unloading. After unloading, the material receiving table 4 descends the specified height again (the same as the previous descent height to achieve step-by-step descent), and then waits for the next unloading, continuously repeating the above process; until the material receiving table 4 is stacked full of paper tray finished products, the material receiving table 4 moves to the lowest position, and then the paper tray finished products in the material receiving table 4 are taken out.

[0027] A pulp suction station 22 is also provided on the machine body 5. A pulp bucket 23 for storing pulp is provided at the pulp suction station 22. The moving device can drive the upper die assembly 1 to move to the pulp suction station 22. Then the upper die assembly 1 sucks the pulp in the pulp bucket 23. After that, the upper die assembly 1 moves to the forming station 6 to form products. After the products are formed, the upper die assembly 1 drives the paper tray finished products to move to the unloading station 7 for unloading. After unloading, the upper die assembly 1 moves to the pulp suction station 22 again to suck pulp, and then continuously repeats the above process.

[0028] The upper die assembly 1 is provided with a vacuum suction pipe 24 and suction holes 25. The vacuum suction pipe 24 is respectively connected to the suction holes 25 and a vacuum pump. When the vacuum pump works, the upper die assembly 1 adsorbs the pulp or the paper tray finished product through the suction holes 25. When discharging, the vacuum pump stops working, so that the paper tray finished product on the upper die assembly 1 falls onto the receiving table 4.

[0029] The lifting assembly 3 includes a first lead screw 8, a first nut 9 and a sliding mounting plate 10. The driving assembly 2 is drivingly connected to the first lead screw 8.

The driven wheel 13 is cooperatively connected with the first lead screw 8. The first driver 11 is a servo motor. The first driver 11 drives the driving wheel 12 to rotate. The driving wheel 12 drives the driven wheel 13 to rotate through the synchronous belt, and then drives the first lead screw 8 to rotate, so that the first nut 9 drives the sliding mounting plate 10 to slide up and down, and finally drives the receiving table 4 to lift up and down.

[0031] The machine body 5 is provided with a guide rod 14. The sliding mounting plate 10 is provided with a slider 15. The sliding mounting plate 10 is guided to slide up and down on the guide rod 14 through the slider 15.

The transmission assembly is drivingly connected to the moving mounting plate 17. The upper die assembly 1 is fixed on the moving mounting plate 17. The moving mounting plate 17 is horizontally slidably arranged on the machine body 5. The second driver 16 is a cylinder.

[0033] The transmission assembly includes a second lead screw 18 and a second nut 19. The second driver 16 is drivingly connected to the second lead screw 18. The second nut 19 is horizontally movably arranged on the second lead screw 18. The moving mounting plate 17 is cooperatively connected with the second nut 19. The second driver 16 drives the second lead screw 18 to rotate, so that the second nut 19 drives the moving mounting plate 17 to move horizontally, and then drives the upper die assembly 1 to move horizontally.
