Description

Technical Field

[0001] This utility model relates to the field of paper packaging processing equipment technology, and more specifically, to a stacking device for paper packaging processing. Background Technology

[0002] Paper packaging refers to containers, wrappings, or protective layers primarily made of paper or cardboard, used for the containment, protection, transportation, display, and sale of various products. Simply put, it consists of boxes, bags, cans, and so on, made of paper. Boxed paper packaging is primarily composed of cardboard, and in the paper packaging processing industry, the automated stacking of packaging cardboard has become a crucial step in the production process. The large-scale production of paper packaging products places higher demands on the efficiency, precision, and stability of stacking equipment.

[0003] For example, the patent with publication number CN217946917U provides a cardboard staggered stacking device, which includes a base, a receiving platform, a support platform, and a rotating seat. The cardboard is conveyed to the receiving platform by a conveying device, and after being picked up by the suction device, it rotates 180° to place the cardboard in conjunction with the telescopic component. This device can save time in picking up cardboard and improve work efficiency.

[0004] The aforementioned patent employs a single-sheet cardboard stacking process: after the cardboard is conveyed by a conveyor, the equipment individually picks it up using a suction device, moves it, and places it in the stacking area, completing the stacking process for each cardboard sheet. This method requires each cardboard sheet to repeat the "pick-move-place" cycle, resulting in a long travel distance and a high proportion of idle travel, leaving significant room for improvement in production efficiency. Therefore, this utility model provides a stacking device for paper packaging processing. Utility Model Content

[0005] The purpose of this invention is to provide a stacking device for paper packaging processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacking device for paper packaging processing, comprising a support frame and a conveying mechanism, wherein the support frame has two sets, and the conveying mechanism is disposed below the support frame, and further comprising:

[0007] A longitudinal moving mechanism is slidably mounted above the two sets of support frames;

[0008] A lateral movement mechanism, which drives the longitudinal movement mechanism to move laterally;

[0009] A vertical moving mechanism, which is fixed to the outer end of the slide of the longitudinal moving mechanism;

[0010] A clamping and stacking mechanism is installed at the lower end of the vertical moving mechanism. It includes a mounting base, a bidirectional cylinder is fixed to the lower end of the mounting base, and clamping plates are fixed to both protruding ends of the bidirectional cylinder. Two support brackets with extension heads fixed horizontally at their lower ends are fixed to the rear side of the upper end of the mounting base.

[0011] Preferably, the lower end of the clamping plate is provided with a horizontal bend, and both the lower end bend of the clamping plate and the upper side of the end of the extension head are set at an angle.

[0012] Preferably, the distance between the support frame and the clamping plate should be greater than half the length of the packaging cardboard.

[0013] Preferably, the inner side of the extension head is provided with a through groove, and multiple pulleys are rotatably connected inside the through groove.

[0014] Preferably, the lateral movement mechanism includes a motor fixedly installed at the outer end of the longitudinal movement mechanism, the output end of the motor is fixedly connected to a gear, the gear meshes with a rack, and the rack is installed on the upper end face of the support frame.

[0015] Preferably, the conveying mechanism includes a conveyor belt body, and limit plates are provided on both sides of the conveyor belt body, the direction of the limit plates being parallel to the conveying direction of the conveyor belt body.

[0016] Preferably, a screw is rotatably connected to the middle of the outer side of the limiting plate, and guide rods are fixedly connected to both ends of the outer side of the limiting plate. Multiple connecting seats are fixedly connected to both sides of the conveyor belt body. The screw and guide rods are respectively threaded and slidably connected to the corresponding connecting seats.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This device utilizes a clamping and stacking mechanism to achieve batch stacking and transfer of multiple cardboard sheets, resulting in higher efficiency compared to the traditional single-sheet stacking method. Traditional solutions require each cardboard sheet to independently complete a "pick-up-move-place" cycle, which is repetitive and time-consuming. This device, however, can continuously handle multiple cardboard sheets at the same station, using a stepped descent of a vertical moving mechanism to achieve layer-by-layer stacking. After a single clamping, the entire stack is transferred via a three-axis moving mechanism. This batch processing mode significantly shortens the equipment's travel distance per cardboard sheet, reduces idle travel time and wear on mechanical parts, and transforms the production rhythm from "single-sheet intermittent" to "batch continuous," thereby effectively improving production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, a stacking device for paper packaging processing includes a support frame 1 and a conveying mechanism 6. The support frame 1 has two sets, and the conveying mechanism 6 is located on the lower side of the support frame 1. A longitudinal moving mechanism 3 is slidably connected between the two sets of support frames 1 via a slide rail. The longitudinal moving mechanism 3 adopts the linear module structure of a screw motor in the prior art, and a transverse moving mechanism 2 is installed on one side of the housing of the longitudinal moving mechanism 3.

[0026] The lateral moving mechanism 2 includes a motor 21 fixedly installed at the outer end of the longitudinal moving mechanism 3. The output end of the motor 21 is fixedly connected to a gear 22, and the gear 22 is meshed with a rack 23. The rack 23 is installed on the upper surface of the support frame 1 on one side. During operation, the motor 21 drives the gear 22 to rotate, thereby driving the longitudinal moving mechanism 3 to move above the support frame 1.

[0027] A vertical moving mechanism 4 is fixedly installed on the outside of the slide of the longitudinal moving mechanism 3. The vertical moving mechanism 4 adopts a cylinder lifting structure, mainly including a cylinder, constraint rods on both sides and a lifting seat at the lower end. The lower lifting seat is driven to move by controlling the extension and retraction of the cylinder. A clamping and stacking mechanism 5 is fixedly installed at the lower end of the lifting seat of the longitudinal moving mechanism 4. The clamping and stacking mechanism 5 is used to receive the packaging cardboard conveyed by the conveying mechanism 6. At the same time, the two sets of three moving mechanisms with horizontal, longitudinal and vertical directions give the clamping and stacking mechanism 5 three degrees of freedom in three axes, which can flexibly transfer the stacked packaging cardboard to the placement area.

[0028] The clamping and stacking mechanism 5 includes a mounting base 51. A bidirectional cylinder 52 is fixed to the lower end of the mounting base 51. A clamping plate 53 is fixed to each of the two extended ends of the bidirectional cylinder 52. Two support brackets 54 are fixed to the rear side of the upper end of the mounting base 51. There is a space between the two support brackets 54, which is suitable for improving the stress stability of the packaging cardboard. An extension head 55 is fixed to the lower end of the support bracket 54 in the horizontal direction. The lower end of the clamping plate 53 is provided with a horizontal bend, which facilitates the support of the packaging cardboard entering by the conveying mechanism 6 together with the extension head 55 of the support bracket 54.

[0029] Specifically, during operation, the cardboard is conveyed sequentially by the conveying mechanism 6. After detaching from the edge, it falls into the clamping and stacking mechanism 5. The cardboard inside the clamping and stacking mechanism 5 is constrained by the semi-enclosed structure formed by the clamping plates 53 on both sides and the support frame 54 on the rear side to prevent it from falling. After one cardboard is inserted, the cylinder of the vertical moving mechanism 4 extends downward a certain distance, causing the support surface of the clamping and stacking mechanism 5 to drop, so that the next cardboard can be inserted. This continues until the cardboard is stacked to the maximum load capacity. Then, the bidirectional cylinder 52 drives the two clamping plates 53 to clamp the stacked cardboard, ensuring the stability of the cardboard during subsequent transfer and preventing it from falling. At the same time, the clamping action can also align the cardboard and improve its neatness.

[0030] After clamping is completed, the clamping and stacking mechanism 5 is lowered onto the placement area by the coordinated action of the lateral moving mechanism 2, the longitudinal moving mechanism 3, and the vertical moving mechanism 4. The bidirectional cylinder 52 is activated to release the clamping plate 53, releasing the clamping on both sides of the packaging cardboard. Then, the lateral moving mechanism 2 drives the longitudinal moving mechanism 3 to move backward a certain distance until the extension head 55 is completely separated from the bottom of the cardboard, thus completing a single stacking.

[0031] This method, which involves stacking multiple packaging cardboard sheets first using the clamping and stacking mechanism 5 before placing them, allows for continuous handling of multiple cardboard sheets at the same workstation, compared to the traditional method of stacking one cardboard sheet at a time. The vertical moving mechanism 4 descends in a step-by-step manner to achieve layer-by-layer stacking, and the entire stack of cardboard sheets is transferred after a single clamping operation. This reduces the time spent on empty travel and the wear and tear on mechanical parts in the traditional intermittent single-sheet stacking method, effectively improving production efficiency.

[0032] It should be noted that when the packaging cardboard enters the clamping and stacking mechanism 5, its end contacts the support frame 54. The distance between the support frame 54 and the clamping plate 53 must be greater than half the length of the packaging cardboard. That is, the clamping position of the clamping plate 53 must exceed the halfway line of the packaging cardboard, so as to ensure that the packaging cardboard can fall stably into the semi-enclosed structure formed by the clamping plate 53 and the support frame 54, and at the same time ensure the stability of the cardboard during subsequent transfer.

[0033] In addition, the maximum load capacity of 5 depends on the height of 53, that is, the maximum stacking height of the cardboard must not exceed the top height of 53.

[0034] In this embodiment, the lower end of the clamping plate 53 is bent and the upper end of the extension head 55 is set at an angle. The inner side of the extension head 55 is provided with a through groove, and multiple pulleys 56 are rotatably connected inside the through groove. The pulleys 56 can reduce the friction with the bottom cardboard, making it easier for the cardboard to detach. The angle can improve the smoothness of the transition when the cardboard is lowered.

[0035] The conveying mechanism 6 includes a conveyor belt body 61. Limiting plates 62 are provided on both sides of the conveyor belt body 61. The limiting plates 62 are flat and their setting direction is parallel to the conveying direction of the conveyor belt body 61. When the packaging paperboard enters the conveyor belt body 61, the limiting plates 62 on both sides can constrain the posture of the packaging paperboard, prevent the packaging paperboard from tilting in the direction before entering the clamping and stacking mechanism 5, and improve the neatness of subsequent stacking.

[0036] In addition, to accommodate packaging cardboard of different specifications, a screw 64 is rotatably connected to the middle of the outer side of the limiting plate 62, while guide rods 65 are fixedly connected to both ends of the outer side of the limiting plate 62. Multiple connecting seats 63 are fixedly connected to both sides of the conveyor belt body 61. The screw 64 and guide rods 65 are respectively threaded and slidably engaged with the corresponding connecting seats 63. During use, the distance between the two limiting plates 62 is adjusted by rotating the screw 64, thereby adapting to packaging cardboard of different specifications.

[0037] Working principle: During use, the cardboard is conveyed by the conveyor belt body 61 of the conveying mechanism 6. The spacing of the limit plates 62 on both sides is adjusted by the screws 64 to constrain the posture of the cardboard and prevent tilting. After the cardboard leaves the edge of the conveying mechanism, it falls into the clamping and stacking mechanism 5 and is constrained by the semi-enclosed structure formed by the clamping plates 53 on both sides and the rear support frame 54. The distance between the support frame 54 and the clamping plates 53 is more than half the length of the cardboard to ensure stable support.

[0038] After a single cardboard piece falls in, the cylinder of the vertical moving mechanism 4 drives the lifting seat to descend a certain distance, lowering the supporting surface of the clamping and stacking mechanism 5 so that the next cardboard piece can continue to fall into the stack. This process is repeated until the cardboard is stacked to the maximum load capacity. At this point, the bidirectional cylinder 52 pushes the clamping plate 53 to clamp the stacked cardboard, aligning the edges and ensuring stability.

[0039] After clamping is completed, the lateral moving mechanism 2 and the longitudinal moving mechanism 3 work together to move the vertical moving mechanism 4 and the clamping and stacking mechanism 5 to the designated placement area. The vertical moving mechanism lowers the cardboard, the bidirectional cylinder releases the clamping plate, and then the lateral moving mechanism 2 drives 5 to move backward, so that the extension head 55 disengages from the bottom of the cardboard, completing one stacking transfer.
