Description

Technical Field

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

[0002] Paperboard, also known as cardboard, is usually distinguished from paper by its weight and thickness. Generally, paper with a thickness greater than 0.5 mm is called paperboard. It is mainly used to manufacture paper packaging boxes, the filling material for packaging boxes, and other types of packaging materials for fragile goods. After the paperboard is produced, it needs to be stacked for subsequent processing.

[0003] In existing technology, finished cardboard is usually stacked on a pallet, and the bottom of the pallet is usually designed with slots for easy insertion of forklifts or handling vehicles to facilitate the handling of the cardboard.

[0004] However, existing pallet structures are simple and can only support and transport cardboard. They lack positioning mechanisms to ensure neat stacking and do not have fixing mechanisms after stacking. Therefore, ropes or other structures are needed to secure the cardboard during transport, which is cumbersome. Furthermore, due to the low height of the pallets, workers need to repeatedly bend over to stack the bottom layer of cardboard, increasing labor intensity. Therefore, it is necessary to propose a cardboard stacking device for packaging box production and processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cardboard stacking device for packaging box production and processing, which facilitates the neat stacking of cardboard and the fixing of cardboard after stacking, thereby facilitating handling. At the same time, it avoids workers from repeatedly bending over during stacking, thereby reducing labor intensity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cardboard stacking device for packaging box production and processing, comprising a base plate and a pallet, a vertical plate fixedly connected to the upper end of the base plate, a horizontal plate fixedly connected to the upper end of the vertical plate, a lead screw rotatably connected to the lower end of the horizontal plate, a motor with its output end fixedly connected to the lead screw installed at the upper end of the horizontal plate, a lifting block threadedly connected to the outer wall of the lead screw, a support plate fixedly connected to the right end of the lifting block, and a pallet placed on the upper end of the support plate;

[0007] The upper surface of the pallet is fixedly connected to the left and right sides of the upper surface, and the upper surface of the pallet is fixedly connected to the rear side of the upper surface. The front ends of the two first positioning strips are fixedly connected to symmetrically distributed guide ramps.

[0008] Two pressure plates are slidably connected to the opposite sides of the two first positioning strips via two sliding grooves. A horizontal plate is fixedly connected to the upper end of the two first positioning strips. A screw rod that is rotatably connected to the upper end of the pressure plate is threaded through and threaded to the upper end of the horizontal plate.

[0009] A fixing mechanism is provided at the upper end of the support plate.

[0010] In order to clamp and fix the pallet and thus improve its stability, the preferred method of the cardboard stacking device for packaging box production and processing according to this utility model includes a fixing clamp plate fixedly connected to the upper end of the support plate and abutting against the left end of the pallet. The upper end of the support plate is fixedly connected to a connecting plate located on the right side of the pallet. A hydraulic cylinder is installed at the right end of the connecting plate. The output end of the hydraulic cylinder passes through the connecting plate and is fixedly connected to a movable clamp plate that abuts against the right end of the pallet.

[0011] In order to withstand the bending torque of the lead screw and at the same time improve the stability of the lifting block's up and down movement, as a preferred embodiment of the cardboard stacking device for packaging box production and processing of this utility model, a T-shaped groove is provided at the right end of the vertical plate, and a T-shaped slider that is fixedly connected to the left end of the lifting block is slidably connected inside the T-shaped groove.

[0012] To improve the stability of the lead screw rotation, in a preferred embodiment of the cardboard stacking device for packaging box production and processing according to this utility model, the lead screw is rotatably connected to the upper end of the base plate.

[0013] To facilitate the rotation of the screw, a handwheel is preferably fixedly connected to the upper end of the screw in a preferred embodiment of the cardboard stacking device for packaging box production and processing according to this utility model.

[0014] To facilitate the installation and fixation of the base plate, in a preferred embodiment of the cardboard stacking device for packaging box production and processing according to this utility model, both the left and right ends of the base plate are fixedly connected to mounting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The pallet is supported by a support plate, and when the motor drives the lead screw to rotate, the pallet can be moved upward until the top of the pallet is at a comfortable height for stacking cardboard. Then, the cardboard after production is stacked between the two first positioning strips, and the rear end of the cardboard contacts the front end of the second positioning strip. The length of the cardboard matches the spacing between the two first positioning strips, so as to facilitate the neat stacking of cardboard.

[0017] During the stacking of cardboard, the pallet and the stacked cardboard move slowly downwards. The speed at which the pallet moves downwards can be determined according to the stacking speed of the workers, thus allowing the workers to work in a comfortable state and thereby achieving the goal of improving and reducing labor intensity.

[0018] When the cardboard is stacked close to the pressure plate, turn the screw to move the pressure plate downwards and press the cardboard tightly against each other, thereby squeezing and fixing the cardboard for easy handling. Attached Figure Description

[0023] Please see Figures 1 to 3 A cardboard stacking device for packaging box production and processing includes a base plate 1 and a pallet 8. A vertical plate 2 is fixedly connected to the upper end of the base plate 1, a horizontal plate 5 is fixedly connected to the upper end of the vertical plate 2, a lead screw 3 is rotatably connected to the lower end of the horizontal plate 5, a motor 6 with its output end fixedly connected to the lead screw 3 is installed at the upper end of the horizontal plate 5, a lifting block 4 is threadedly connected to the outer wall of the lead screw 3, a support plate 7 is fixedly connected to the right end of the lifting block 4, and a pallet 8 is placed on the upper end of the support plate 7.

[0024] First positioning strips 9 are fixedly connected to both the left and right sides of the upper surface of the pallet 8, and second positioning strips 10 are fixedly connected to the rear side of the upper surface of the pallet 8. Symmetrically distributed guide ramps 20 are fixedly connected to the front ends of the two first positioning strips 9.

[0025] Two first positioning strips 9 are slidably connected to pressure plates 13 on opposite sides via two sliding grooves. A horizontal plate 11 is fixedly connected to the upper end of the two first positioning strips 9. A screw 12, which is rotatably connected to the upper end of the pressure plate 13, passes through and is threaded to the upper end of the horizontal plate 11.

[0026] A fixing mechanism is provided at the upper end of the support plate 7.

[0027] In this embodiment: During use, the initial position of the support plate 7 is close to the bottom side, and the support plate 7 supports the pallet 8. The pallet 8 is then fixed by the fixing mechanism to improve the stability of the pallet 8. Subsequently, the motor 6 drives the lead screw 3 to rotate, which in turn drives the lifting block 4 to move upward, and at the same time drives the support plate 7 and the pallet 8 to move upward until the upper end of the pallet 8 is at a comfortable height for stacking cardboard. Then, the cardboard that has been transported by the conveyor or other device after production is stacked between the two first positioning strips 9, and the rear end of the cardboard contacts the front end of the second positioning strip 10. The length of the cardboard matches the distance between the two first positioning strips 9, and the cardboard can easily enter the position between the two first positioning strips 9 through the guiding action of the two guide inclined plates 20, thereby achieving the purpose of stacking the cardboard neatly.

[0028] During the stacking of cardboard, the motor 6 drives the lead screw 3 to rotate, which in turn drives the lifting block 4 to move slowly downward. At the same time, the support plate 7, the pallet 8, and the stacked cardboard move slowly downward. The speed at which the pallet 8 moves downward can be determined according to the stacking speed of the workers, so that the workers can always work in a comfortable state, thereby achieving the goal of improving and reducing labor intensity.

[0029] When the cardboard is stacked close to the pressure plate 13, the support plate 7 moves downward to the initial position, the screw 12 is rotated, and the pressure plate 13 moves downward due to the limiting effect of the two slides until the pressure plate 13 is in close contact with the cardboard, so that the cardboard can be squeezed and fixed to facilitate handling.

[0030] Then the fixing mechanism is released from the fixed state of the pallet 8, and the pallet 8 and cardboard are moved by a forklift.

[0031] As a technical optimization of this utility model, the fixing mechanism includes a fixed clamping plate 14 fixedly connected to the upper end of the support plate 7 and abutting against the left end of the pallet 8. A connecting plate 15 located on the right side of the pallet 8 is fixedly connected to the upper end of the support plate 7. A hydraulic cylinder 16 is installed at the right end of the connecting plate 15. The output end of the hydraulic cylinder 16 passes through the connecting plate 15 and is fixedly connected to a movable clamping plate 17 abutting against the right end of the pallet 8.

[0032] In this embodiment: the hydraulic cylinder 16 drives the movable clamping plate 17 to move to the left, thereby pushing the pallet 8 to move to the left. In turn, the movable clamping plate 17 and the fixed clamping plate 14 can clamp and fix the pallet 8, thereby improving the stability of the pallet 8.

[0033] As a technical optimization of this utility model, a T-shaped groove 18 is provided at the right end of the vertical plate 2, and a T-shaped slider 19 that is fixedly connected to the left end of the lifting block 4 is slidably connected inside the T-shaped groove 18.

[0034] In this embodiment, by setting the T-shaped groove 18 and the T-shaped slider 19, the bending torque of the lead screw 3 can be withstood, and the stability of the lifting block 4 moving up and down can be improved at the same time.

[0035] As a technical optimization of this utility model, the lead screw 3 is rotatably connected to the upper end of the base plate 1.

[0036] In this embodiment, by rotating the lead screw 3 to the upper end of the base plate 1, the stability of the lead screw 3 rotation can be improved.

[0037] As a technical optimization of this utility model, a handwheel is fixedly connected to the upper end of the screw 12.

[0038] In this embodiment: a handwheel is provided to facilitate the rotation of screw 12.

[0039] As a technical optimization of this utility model, mounting plates are fixedly connected to both the left and right ends of the base plate 1.

[0040] In this embodiment, two mounting plates are provided to facilitate the installation and fixation of the base plate 1.

[0041] Working principle: In use, the support plate 7 is initially positioned close to the bottom side, and supports the pallet 8. Then, the hydraulic cylinder 16 drives the moving clamp 17 to move to the left, thereby pushing the pallet 8 to move to the left. In conjunction with the moving clamp 17 and the fixed clamp 14, the pallet 8 can be clamped and fixed, thereby improving the stability of the pallet 8. Subsequently, the motor 6 drives the lead screw 3 to rotate, thereby driving the lifting block 4 to move upward, and simultaneously driving the support plate 7 and the pallet 8 to move upward until the upper end of the pallet 8 is at a comfortable height for stacking cardboard. Then, the cardboard that has been transported by the conveyor or other device after production is stacked between the two first positioning bars 9, and the rear end of the cardboard contacts the front end of the second positioning bar 10. The length of the cardboard matches the distance between the two first positioning bars 9, and the guiding action of the two guide inclined plates 20 facilitates the cardboard to enter the position between the two first positioning bars 9, thereby achieving the purpose of stacking the cardboard neatly.

[0042] During the stacking of cardboard, the motor 6 drives the lead screw 3 to rotate, which in turn drives the lifting block 4 to move slowly downward. At the same time, the support plate 7, the pallet 8, and the stacked cardboard move slowly downward. The speed at which the pallet 8 moves downward can be determined according to the stacking speed of the workers, so that the workers can always work in a comfortable state, thereby achieving the goal of improving and reducing labor intensity.

[0043] When the cardboard is stacked close to the pressure plate 13, the support plate 7 moves downward to the initial position. Then, the screw 12 is rotated by the handwheel, and the pressure plate 13 moves downward due to the limiting effect of the two slides until the pressure plate 13 is in close contact with the cardboard, so that the cardboard can be squeezed and fixed to facilitate handling.

[0044] Then, the fixed state of the pallet 8 is released by moving the clamp 17 to the right, and the pallet 8 and the cardboard are then moved by a forklift.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
