DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the packaging machine has an automatic three-layer stacking mechanism, which includes three conveying paths which are distributed at intervals and carry upper, middle and lower layer materials 26 respectively. The conveying path carrying the lower layer material 26 and the conveying path carrying the middle layer material 25 are staggered up and down. The conveying path carrying the lower layer material 26 and the conveying path carrying the middle layer material 25 merge at the end of the conveying path carrying the middle layer material 25 so that the middle layer material 25 falls onto the lower layer material 26 to form the first material stacking. The conveying path carrying the upper layer material 24 and the conveying path carrying the lower layer material 26 merge at the end of the conveying path carrying the upper layer material 24 so that the upper layer material 24 falls onto the middle layer material 25 to form the second material stacking. The conveying path carrying the upper layer material 24 is conveying path A1, the conveying path carrying the middle layer material 25 is conveying path B2, and the conveying path carrying the lower layer material 26 is conveying path C3.

[0028] Preferably, a conveying mechanism 5 for conveying the upper, middle and lower materials into conveying path A1, conveying path B2 and conveying path C3 respectively and a driving motor for controlling the transmission of the conveying mechanism 5 are provided on one side of the stacking mechanism. The conveying mechanism 5 is composed of a first conveyor belt 6 corresponding to conveying path A1, a second conveyor belt 7 corresponding to conveying path B2 and a third conveyor belt 8 corresponding to conveying path C3.

[0029] The conveyor path C3 has a sinking section 4. Detailed description: The conveyor path C3 has a sinking section 4 or an ascending section. When the conveyor path C3 has the sinking section 4, since the conveyor paths B2 and C3 are staggered in upper and lower distribution, the conveyor path B2 can be designed as a flat road or have an ascending section or a sinking section 4, and the sinking section 4 of the conveyor path B2 is higher than the sinking section 4 of the conveyor path C3; when the conveyor path C3 has an ascending section, similarly, the conveyor path B2 can be designed as a flat road or have an ascending section or a sinking section 4, and no matter it is a flat road design or an ascending section or a sinking section 4, it is higher than the ascending section of the conveyor path C3; the conveyor path A1 can also be designed as a flat road or have an ascending section or a sinking section 4.

[0030] The conveying path A1 includes a first guide groove 9 and a first feeding mechanism. The first guide groove 9 is arranged in a curved shape. The first feeding mechanism can push the material forward along the first guide groove 9. The first feeding mechanism is located below the first guide groove 9. The first feeding mechanism is composed of a first motor unit 10, a first transmission chain 11 and a first material hook 12. The first transmission chain 11 is controlled by the first motor unit 10 to operate in a circulation manner. The first material hook 12 is arranged on the first transmission chain 11 and moves with the operation of the first transmission chain 11. The first material hook 12 can be extended into the first guide groove 9. The first motor unit 10 controls the operation of the first transmission chain 11 to drive the first material hook 12 to extend into the first guide groove 9 and drive the material to move forward along the first guide groove 9.

[0031] The conveying path B2 includes a second guide groove 13 and a second feeding mechanism. The second feeding mechanism can push the material forward along the second guide groove 13. The second feeding mechanism is located below the second guide groove 13. The second feeding mechanism is composed of a second motor unit 14, a second transmission chain 15 and a second material hook 16. The second transmission chain 15 is controlled by the second motor unit 14 to operate in a circulation manner. The second material hook 16 is arranged on the second transmission chain 15 and moves with the operation of the second transmission chain 15. The second material hook 16 can extend into the second guide groove 13. The second motor unit 14 controls the operation of the second transmission chain 15 to drive the second material hook 16 to extend into the second guide groove 13 and drive the material to move forward along the second guide groove 13.

[0032] The conveying path C3 includes a third guide groove 17 and a third feeding mechanism. The third guide groove 17 has a sinking section 4. The third feeding mechanism can push the material forward along the third guide groove 17. The third feeding mechanism is located below the third guide groove 17. The third feeding mechanism is composed of a third motor unit 18, a third transmission chain 19 and a third material hook 20. The third transmission chain 19 is controlled by the third motor unit 18 to operate in a circulation manner. The third material hook 20 is arranged on the third transmission chain 19 and moves with the operation of the third transmission chain 19. The third material hook 20 can extend into the third guide groove 17. The third motor unit 18 controls the operation of the third transmission chain 19 to drive the third material hook 20 to extend into the third guide groove 17 and drive the material to move forward along the third guide groove 17.

[0033] The stacking mechanism also includes a workbench 21 for setting up the conveying path A1, the conveying path B2 and the conveying path C3. The first feeding mechanism, the second feeding mechanism and the third feeding mechanism are all located below the workbench 21. A middle partition plate 22 is arranged above the workbench 21 between the conveying path A1 and the conveying path C3. Limiting plates 23 are arranged on both sides of the first guide groove 9, the second guide groove 13 and the third guide groove 17.

[0034] Working process: the driving motor controls the transmission of the first conveyor belt 6, the second conveyor belt 7 and the third conveyor belt 8 in the conveying mechanism 5, and the first conveyor belt 6, the second conveyor belt 7 and the third conveyor belt 8 synchronously convey the upper material 24, the middle material 25 and the lower material 26 to the first guide groove 9, the second guide groove 13 and the third guide groove 17 in the conveying path A1, the conveying path B2 and the conveying path C3 respectively. At the same time, the first motor part 10, the second motor part 14 and the third motor part 18 respectively control the operation of the first transmission chain 11, the second transmission chain 15 and the third transmission chain 19, thereby driving the first material hook 12, the second material hook 16 and the third material hook 20 to extend into the first guide groove 9, the second guide groove 13 and the third guide groove 17 in the conveying path A1, the conveying path B2 and the conveying path C3 respectively. The guide groove 9, the second guide groove 13 and the third guide groove 17 push the corresponding materials forward. Since the travel distances set by the guide grooves are different, the materials in the third guide groove 17 first merge with the materials in the second guide groove 13 at the end of the second guide groove 13, so that the materials are stacked into two layers. At this time, the second material hook 16 is separated from the conveying path where it is located, and the third material hook 20 continues to push the double-layer materials forward. After that, the materials in the first guide groove 9 and the materials in the third guide groove 17 are merged at the end of the sinking section 4 of the third guide groove 17, so that the materials are stacked into three layers. At this time, the third material hook 20 is separated from the conveying path where it is located, and the first material hook 12 pushes the three-layer materials out of the stacking mechanism.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
