Abstract

This utility model discloses a separation and stacking mechanism, including a frame, a feeding mechanism and a stacking mechanism mounted on the frame. The feeding mechanism consists of an upper conveying mechanism and a lower conveying mechanism. One end of the lower conveying mechanism is hinged to the frame, and the other end is mounted on the frame via a first cylinder. The stacking mechanism includes a side baffle, a front baffle and a conveyor belt. A photoelectric sensor is mounted on one side of the feeding mechanism, and a reflector that works in conjunction with the photoelectric sensor is mounted on the front baffle. When a certain number of paper bags are stacked and block the photoelectric sensor, the first cylinder is controlled to retract, causing the feeding mechanism to tilt.

Description

Technical Field

[0001] This utility model relates to a paper bag production line, and more particularly to a separation and stacking mechanism. Background Technology

[0002] Currently, paper bag production is mostly a continuous operation. How to quickly and neatly stack paper bags at the end of the production line has become a major challenge. Traditional stacking methods mainly rely on manual operation. Workers need to manually remove continuously produced paper bags from the production line and stack them one by one. This method is extremely inefficient and cannot keep up with the pace of high-speed production lines, greatly restricting the improvement of production efficiency. At the same time, manually stacked paper bags have obvious shortcomings in terms of neatness, and paper bags are prone to misalignment and uneven height. This not only affects the convenience of subsequent handling, but may also cause paper bags to collapse during storage due to unstable stacking, resulting in product damage and resource waste. In addition, manual operation is labor-intensive, and long-term operation can easily cause worker fatigue, thereby increasing the probability of errors and further affecting production quality and efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a separation and stacking mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A separation and stacking mechanism includes a frame, on which a feeding mechanism and a stacking mechanism are mounted. The feeding mechanism consists of an upper conveying mechanism and a lower conveying mechanism. One end of the lower conveying mechanism near the stacking mechanism is hinged to the frame, and the other end is mounted on the frame via a first cylinder that drives the end of the lower conveying mechanism to rise and fall. The stacking mechanism includes a side baffle that can be adjusted left and right, a front baffle that can be flipped open, and a conveyor belt for conveying stacked paper bags. A photoelectric sensor is mounted on the side of the feeding mechanism near the stacking mechanism, and a reflector that works in conjunction with the photoelectric sensor is mounted on the front baffle.

[0006] A vertical rack is symmetrically mounted on one side of the first cylinder on the frame, and a gear is mounted on the lower conveying mechanism corresponding to the rack, with the rack meshing with the gear.

[0007] The upper conveying mechanism consists of a conveyor wheel assembly and a conveyor belt. A connecting rod is hinged to the lower side of the upper conveying mechanism, and a swing wheel is installed on the connecting rod to press the conveyor belt toward the lower conveying mechanism.

[0008] The upper conveying mechanism is equipped with a screw driven by a first motor along the conveying direction of the paper bag. A swing wheel bracket is threaded onto the screw, and the connecting rod is rotatably mounted on the swing wheel bracket.

[0009] A crossbar is installed on the stacking mechanism, and adjusting cylinders for driving the side baffles to move are symmetrically installed on the crossbar.

[0010] An adjusting block is installed on the crossbar via a threaded structure. The telescopic shaft of the adjusting cylinder is connected to the adjusting block, and the housing of the adjusting cylinder is connected to the side baffle.

[0011] The stacking mechanism is equipped with a rotating rod that rotates synchronously with the front baffle. One end of the rotating rod is connected to the second cylinder via a swing arm.

[0012] One end of the swing arm is mounted on the rotating rod, and the other end is connected to the telescopic shaft of the second cylinder.

[0013] The beneficial effects of this utility model are as follows: This utility model has a feeding mechanism and a stacking mechanism installed on the frame.

A photoelectric sensor is installed on the side of the feeding mechanism near the stacking mechanism. A reflector that works with the photoelectric sensor is installed on the front baffle. When a certain number of paper bags are stacked and block the photoelectric sensor, the first cylinder is controlled to retract, causing the feeding mechanism to tilt. At the same time, the direction of the photoelectric sensor is raised to restore reflection. When the tilt reaches a set degree, the stacking mechanism conveyor belt starts to send away the stacked paper bags, realizing automated stacking. It can match the continuous production rhythm of the production line well, significantly improve the overall production efficiency, reduce errors in human judgment and operation, and improve the reliability and stability of equipment operation.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0023] Reference Figure 1-5 A separation and stacking mechanism includes a frame 1, on which a feeding mechanism 2 and a stacking mechanism 3 are mounted. The feeding mechanism 2 consists of an upper conveying mechanism 4 and a lower conveying mechanism 5. One end of the lower conveying mechanism 5 near the stacking mechanism 3 is hinged to the frame 1, and the other end is mounted on the frame 1 via a first cylinder 6 that drives the end of the lower conveying mechanism 5 to rise and fall. The stacking mechanism 3 includes a side baffle 11 that can be adjusted left and right, a front baffle 12 that can be flipped open, and a conveyor belt 13 for conveying stacked paper bags. A photoelectric sensor is mounted on the side of the feeding mechanism 2 near the stacking mechanism 3, and a reflector that works in conjunction with the photoelectric sensor is mounted on the front baffle 12.

[0024] When the number of paper bags stacked to a certain extent obstructs the photoelectric sensor, the first cylinder 6 is controlled to retract, causing the feeding mechanism 2 to tilt. At the same time, the irradiation direction of the photoelectric sensor is raised to restore reflection. When the tilt reaches a set degree, the conveyor belt 13 of the stacking mechanism 3 starts to send away the stacked paper bags, realizing automated stacking. This can match the continuous production rhythm of the production line well, significantly improve the overall production efficiency, reduce errors in human judgment and operation, and improve the reliability and stability of equipment operation.

[0025] A vertical rack 14 is symmetrically mounted on one side of the first cylinder 6 on the frame 1. A gear 15 is mounted on the lower conveying mechanism 5 corresponding to the rack 14. The rack 14 and the gear 15 mesh. On the one hand, the gear 15 and the rack 14 play a guiding role, improving the stability of the lifting and lowering of one end of the lower conveying mechanism 5. On the other hand, the gear meshing has high transmission accuracy, which can accurately adjust the descent distance of the lower conveying mechanism 5, that is, improve the accuracy of the irradiation direction of the photoelectric sensor, thereby improving the consistency of the number of paper bags stacked at one time.

[0026] The upper conveying mechanism 4 consists of a conveying wheel set 7 and a conveying belt 8. A connecting rod 9 is hinged to the lower side of the upper conveying mechanism 4. A swing wheel 10 is installed on the connecting rod 9 to press the conveying belt 8 against the lower conveying mechanism 5. When one end of the lower conveying mechanism 5 descends and forms an inclined state, the swing wheel 10 and the connecting rod 9 swing downward due to gravity, so that the conveying belt 8 and the conveying belt of the lower conveying mechanism 5 are always at a reasonable distance.

[0027] Furthermore, the upper conveying mechanism 4 is equipped with a screw 17 driven by the first motor 16 along the conveying direction of the paper bag. A swing wheel bracket 18 is threaded onto the screw 17. The connecting rod 9 is rotatably mounted on the swing wheel bracket 18. The position of the swing wheel bracket 18 can be adjusted according to the length of the paper bag, thereby ensuring that the position of the swing wheel 10 is in a reasonable orientation and improving the conveying efficiency of the upper conveying mechanism 4.

[0028] The stacking mechanism 3 is equipped with a crossbar 19 driven by a second motor 25. A regulating cylinder 20 for driving the side baffle 11 is symmetrically mounted on the crossbar 19. An adjusting block 21 is threaded onto the crossbar 19. The telescopic shaft of the regulating cylinder 20 is connected to the adjusting block 21. The housing of the regulating cylinder 20 is connected to the side baffle 11. When the paper bags are stacked, the regulating cylinder 20 is driven, causing the side baffle 11 to move outward, completely releasing the paper bags and preventing them from getting stuck.

[0029] Furthermore, a limiting rod 26 is installed on the stacking mechanism 3. The upper side of the side baffle 11 is engaged with the limiting rod 26 through a notch. Driven by the second motor 25, the crossbar 19 rotates. The side baffle 11 is restricted by the limiting rod 26 and cannot rotate synchronously. The adjusting block 21 is fixedly connected to the side baffle 11 and also cannot rotate. Therefore, the threaded structure achieves the effect of moving the side baffle 11 in the left and right directions, thereby adjusting the position of the side baffle 11 and better positioning it in the middle position of the stacking mechanism 3.

[0030] The stacking mechanism 3 is equipped with a rotating rod 22 that rotates synchronously with the front baffle 12. One end of the rotating rod 22 is connected to the second cylinder 24 via a swing arm 23. One end of the swing arm 23 is mounted on the rotating rod 22, and the other end is connected to the telescopic shaft of the second cylinder 24. When the paper bags are stacked, the second cylinder 24 drives the rotating rod 22 to rotate via the swing arm 23, thereby opening the front baffle 12.

[0031] In this application, the discharge position of the feeding mechanism 2 is higher than the stacking position of the stacking mechanism 3. Therefore, when the paper bag moves from the feeding mechanism 2 to the stacking mechanism 3, it will fall downwards. After the paper bag completes one stacking, the highest point of the stacked paper bag is still lower than the discharge position of the feeding mechanism 2.
