[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] As shown in the figure, a processing equipment for vegetable fresh-keeping bags includes a workbench 1, a lower pressure rod 2 is arranged on the surface of the workbench 1, and vertically arranged support plates 3 are arranged on the surface of the workbench 1 at both ends of the lower pressure rod 2. An upper pressure rod 4 is slidably connected between the two support plates 3 in the vertical direction. The upper pressure rod 4 is parallel to and located directly above the lower pressure rod 2, and also includes a first driving member for driving the upper pressure rod 4 to rise and fall. A cutting assembly is also arranged on the upper pressure rod 4.

[0028] During production and processing, several fresh-keeping bags are stacked and placed on the surface of the workbench 1, and the middle strip is placed on the surface of the lower pressure rod 2, so that the bag bodies on both sides can be placed stably on the surface of the workbench 1, and the upper pressure rod 4 is driven downward by the first driving member, and finally pressed against the top of the middle strip, and finally the middle strip is cut by the cutting assembly to form a through hole, thereby cutting through holes in multiple fresh-keeping bags, effectively improving production efficiency.

[0029] A horizontally arranged pressure plate 5 is provided on both sides of the upper pressure rod 4, and a guide block 6 is provided on both side ends of the upper pressure rod 4. Vertical guide grooves are provided on the opposite surfaces of the two guide blocks 6 on the same side, and a sliding plate 7 slidably connected to the guide groove is provided on one side of the pressure plate 5. A horizontally arranged connecting strip 8 is provided on the top of both sides of the upper pressure rod 4, and a vertical connecting rod 9 is provided on the lower surface of the connecting strip 8. A connecting groove for the connecting rod 9 to be inserted and slidably connected is provided on the top of the sliding plate 7. A first spring 10 is fixedly connected between the bottom of the connecting groove and the bottom end of the connecting rod 9, and an abutting rod (not shown in the figure) is also provided at the bottom of the connecting groove. When the connecting rod 9 moves downward and finally abuts against the top of the abutting rod, the first spring 10 is prevented from being damaged by a strong force.

[0030] When the first driving member drives the upper pressure rod 4 to descend, the pressure plate 5 moves downward at the same time and first presses on the surface of the bag body. When the first driving member continues to drive the upper pressure rod 4 to move downward, the sliding plate 7 slides upward relative to the guide block 6 and the first spring 10 is compressed. When the upper pressure rod 4 is pressed tightly against the middle strip, the pressure plate 5 is pressed tightly against the bag body under the elastic force of the first spring 10, thereby further ensuring the stability of the fresh-keeping bag during cutting to improve the cutting effect.

[0031] A groove is provided on the surface of the upper pressure plate 5 along its length direction. The cutting assembly includes a lifting plate 11 arranged in the groove. A cutting ring 12 is provided on the lower surface of the lifting plate 11. The upper pressure plate 5 is provided with a cutting groove 13 running through its bottom and the groove. The cutting ring 12 is penetrated and slidably connected to the cutting groove 13. The lifting plate 11 is slidably connected to the groove along the vertical direction. The top of the inner wall on both sides of the groove is provided with a limiting edge 14 for limiting the lifting plate 11. Both ends of the lower surface of the lifting plate 11 are provided with vertical downward sliding rods 15. The upper pressure plate 5 is provided with a sliding groove 16 running through its bottom and the groove. The sliding rod 15 is slidably connected to the sliding groove 16. Through grooves 17 for sliding connection of the sliding rod 15 are provided at both ends of the surface of the lower pressure rod 2. The sliding rod 15 is located between the lifting plate 11 and the bottom of the groove and is sleeved and fixedly connected with a second spring 18. The first driving member is used to drive the lifting plate 11 to lift and lower.

[0032] When the first driving member drives the lifting plate 11 to descend, it also drives the upper pressure rod 4 and the pressure plate 5 to descend, and the middle strip and the bag body are pressed by the upper pressure rod 4 and the pressure plate 5. After the connecting rod 9 abuts against the top of the abutting rod, the first driving member continues to drive the lifting plate 11 to descend and moves downward along the groove, so that the second spring 18 is compressed, and at the same time drives the cutting ring 12 to move downward, and cuts the middle strip after passing through the cutting groove 13. It should be noted that the stiffness coefficient of the first spring 10 is smaller than the stiffness coefficient of the second spring 18, so that after the first spring is fully compressed, the compression amount of the second spring 18 is much smaller than the compression amount of the first spring.

[0033] A top plate 19 is fixedly connected between the tops of the two support plates 3 . The first driving member is specifically a first cylinder 20 disposed on the surface of the top plate 19 . The piston rod of the first cylinder 20 vertically passes through the top plate 19 downward and is fixedly connected to the lifting plate 11 .

[0034] A waste groove 21 corresponding to the cutting ring 12 is formed on the surface of the lower pressure rod 2 . The waste groove 21 runs through the bottom of the workbench 1 . After the cutting work is performed, the cut waste falls from the bottom of the workbench 1 through the waste groove 21 .

[0035] The surface of the workbench 1 is provided with a sliding groove for the lower pressure rod 2 to slide and connect in the vertical direction, and also includes a second driving component for driving the lower pressure rod 2 to rise and fall, which is specifically a second cylinder (not shown in the figure) arranged at the bottom of the workbench 1. When processing fresh-keeping bags of different specifications, the lower pressure rod 2 can be controlled to rise and fall by the second driving component to control the distance between the top of the lower pressure rod 2 and the surface of the workbench 1, so that the middle strip and the bag body can be placed flat on the surface of the lower pressure strip and the workbench 1.

[0036] A heating component (not shown in the figure) for heating the cutting ring 12 is provided at the bottom of the lifting plate. Before cutting, the cutting ring 12 is heated by the heating component to ensure smooth cutting. After cutting, the heating component stops heating. After cooling, the middle strip is fixed by hot melt, thereby further improving its processing efficiency.

[0037] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
