Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard stacking, and specifically relates to a high-speed corrugated cardboard stacking device that prevents paper jams. Background Technology

[0002] A corrugated cardboard stacking device is a piece of equipment used at the end of an automated production line to neatly stack corrugated cardboard. Its main function is to stack the cut cardboard into a stack according to a preset quantity and direction, facilitating subsequent bundling, transportation, or storage. This device typically consists of a conveying mechanism, a positioning mechanism, a stacking mechanism, and a lifting platform. It achieves efficient stacking by coordinating the actions of each component. However, in the existing technology, the straight-line stacking method has significant drawbacks. When the corners of corrugated cardboard warp, the straight-line stacking method amplifies the cumulative error of the warped cardboard. Since each layer of cardboard is arranged in the same direction, the warped corners will continue to accumulate in the same direction, causing the overall tilt of the stack to intensify with the increase of the number of stacking layers. This leads to subsequent stacked corrugated cardboard colliding with the stacked cardboard, resulting in paper jams. Therefore, we hope to design a high-speed corrugated cardboard stacking device to prevent paper jams and solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed corrugated cardboard stacking device to prevent paper jams and solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a high-speed corrugated cardboard stacking device for preventing paper jams, comprising: a base, a rotating mechanism for adjusting the stacking angle is provided on the upper surface of the base, a tray is provided on the rotating mechanism, and a fixing mechanism for positioning the tray is provided on the rotating mechanism;

[0005] The rotating mechanism includes a support block, with a fixed shaft fixedly sleeved inside the support block. A secondary gear is sleeved on the outer side of the upper end of the fixed shaft via a bearing. A support seat is fixedly connected to the upper surface of the secondary gear. By setting up the rotating mechanism, the corrugated cardboard is arranged in alternating directions to form a stable staggered structure. This avoids errors in stacking height caused by the corners of the corrugated cardboard sticking up when stacked neatly, which could lead to subsequent collisions between the corrugated cardboard and the stacked cardboard, causing paper jams.

[0006] In a preferred embodiment, the rotating mechanism further includes a mounting frame, inside which a drive motor is disposed, and a main gear is fixedly connected to the output shaft of the drive motor, the main gear meshing with a secondary gear.

[0007] In a preferred embodiment, the outer side of the support block is fixedly connected to one side with a reinforcing rib, and the other side of the reinforcing rib is fixedly connected to the upper surface of the base.

[0008] As a preferred embodiment, the upper surface of the tray is provided with an anti-slip pad made of natural rubber to increase its friction with the corrugated cardboard surface.

[0009] In a preferred embodiment, the support base is a U-shaped structure to prevent the tray from sliding left and right.

[0010] In a preferred embodiment, the fixing mechanism includes a support rod, which is fixedly connected to the right side surface of the support base. A connecting plate is slidably sleeved on the outer side of the support rod, and insert rods are fixedly connected to both the front and rear ends of the connecting plate. The insert rods slide through the interior of the support base. By setting the fixing mechanism, the position of the tray is prevented from shifting during the rotation of the support base.

[0011] In a preferred embodiment, the connecting plate and the right side surface of the support base are elastically connected by a tension spring. The elasticity of the tension spring allows the connecting plate to keep the insert rod inside the fitting groove.

[0012] In a preferred embodiment, the right side of the tray has a fitting groove, and the insert rod is slidably sleeved inside the fitting groove.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By setting up a rotating mechanism, the corrugated cardboard is arranged in alternating directions to form a stable staggered structure. This avoids errors in stacking height caused by the curling of the corners of the corrugated cardboard when stacked neatly, which could lead to paper jams caused by subsequent collisions between the corrugated cardboard and the stacked cardboard.

[0015] 2. Position the pallet by setting a fixing mechanism to prevent the pallet from accidentally shifting during rotation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1 as well as Figure 2 As the first embodiment of this utility model:

[0027] A high-speed corrugated cardboard stacking device for preventing paper jams includes: a base 1, a rotating mechanism 2 for adjusting the stacking angle is provided on the upper surface of the base 1, a tray 4 is provided on the rotating mechanism 2, and a fixing mechanism 3 for positioning the tray 4 is provided on the rotating mechanism 2.

[0028] The rotating mechanism 2 includes a support block 23. A fixed shaft is fixedly sleeved inside the support block 23. A secondary gear 25 is sleeved on the outer side of the upper end of the fixed shaft through a bearing. A support seat 26 is fixedly connected to the upper surface of the secondary gear 25. By setting the rotating mechanism 2, the corrugated cardboard is arranged in alternating directions to form a stable staggered structure. This avoids errors in stacking height caused by the corners of the corrugated cardboard being curled up when stacked neatly, which could lead to subsequent collisions between the corrugated cardboard and the stacked cardboard, causing paper jams.

[0029] The rotating mechanism 2 also includes a mounting bracket 21, inside which a drive motor is installed. A main gear 22 is fixedly connected to the output shaft of the drive motor, and the main gear 22 meshes with the secondary gear 25.

[0030] The outer side of the support block 23 is fixedly connected to one side with a reinforcing rib 24 to improve the stability of the support block 23, and the other side of the reinforcing rib 24 is fixedly connected to the upper surface of the base 1.

[0031] The upper surface of the tray 4 is provided with an anti-slip pad 41 made of natural rubber to increase its friction with the corrugated cardboard surface.

[0032] The support base 26 has a U-shaped structure to prevent the tray 4 from sliding left and right.

[0033] Specifically, during the stacking of corrugated cardboard, the corrugated cardboard is first transported to pallet 4 via an external stacking conveyor belt to complete the stacking task. When the corrugated cardboard is stacked to a certain height, the drive motor is started. The output shaft of the drive motor drives the main gear 22, which is fixedly connected to it, to rotate. During the rotation of the main gear 22, the secondary gear 25 meshing with it also rotates. Finally, the secondary gear 25 drives the support seat 26 to rotate 90°, and then the corrugated cardboard is stacked again, so that the corrugated cardboard is arranged in alternating directions to form a stable staggered structure. This prevents the corners of the corrugated cardboard from curling up, which would cause errors in the stacking height and lead to paper jams caused by collisions between the corrugated cardboard and the previous corrugated cardboard during subsequent stacking.

[0034] Please see Figure 1 , Figure 3 as well as Figure 4 As a second embodiment of this utility model:

[0035] The fixing mechanism 3 includes a support rod 31, which is fixedly connected to the right side surface of the support base 26. A connecting plate 32 is slidably sleeved on the outside of the support rod 31. Insert rods 34 are fixedly connected to both the front and rear ends of the connecting plate 32. The insert rods 34 slide through the interior of the support base 26. By setting the fixing mechanism 3, the position of the tray 4 is prevented from shifting during the rotation of the support base 26.

[0036] The connecting plate 32 is elastically connected to the right side surface of the support base 26 by a tension spring 33. The elasticity of the tension spring 33 allows the connecting plate 32 to drive the insertion rod 34 to remain inside the fitting groove 35.

[0037] The right side of the tray 4 has a fitting groove 35, and the insert rod 34 is slidably sleeved inside the fitting groove 35.

[0038] Based on the above embodiments, before stacking the corrugated cardboard, the connecting plate 32 is first pulled. While the connecting plate 32 is moving, the tension spring is stretched to deform it. When the connecting plate 32 drives the insertion rod 34 to move into the inside of the support base 26, the pallet 4 is placed inside the support base 26. Then the connecting plate 32 is released, and under the action of the tension spring, the insertion rod 34 is inserted into the fitting groove 35 of the pallet 4 to complete the fixation of the pallet 4.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
