Description

Technical Field

[0001] This utility model belongs to the field of polyurethane board stacking technology, and in particular, it is a stacking device for stacking polyurethane boards. Background Technology

[0002] During the transport of polyurethane boards, a palletizing device is required. However, existing palletizing devices cannot accurately detect the stacking height of polyurethane boards. When the polyurethane boards are stacked again, they are easily squeezed by a large vertical force, which can cause damage to the polyurethane boards.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN212711720U) describing a stacking device for polyurethane boards. The device includes a frame, a clamping mechanism, a drive mechanism mounted on the frame to drive the clamping mechanism in reciprocating motion, and a lifting mechanism installed between the drive mechanism and the clamping mechanism. The clamping mechanism includes a horizontally positioned worktable, U-shaped steel sections symmetrically fixed to both sides of the worktable and forming cavities with the sides of the worktable, a pair of clamping members horizontally positioned below the worktable and perpendicular to the length direction of the U-shaped steel sections, a transmission assembly slidably disposed within the cavities, and a power source mounted on the two U-shaped steel sections. The power source drives the transmission assembly to move the two clamping members closer to or further away from each other. This application has the effect of reducing labor costs and improving work efficiency. However, the aforementioned patent does not consider that the polyurethane boards might be damaged by large vertical forces. Utility Model Content

[0004] The purpose of this invention is to provide a stacking device for polyurethane boards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stacking device for polyurethane boards, comprising a support frame and a stacking assembly for stacking polyurethane boards. The stacking assembly is disposed in the inner cavity of the support frame and includes a threaded plate and a movable plate. Two electric push rods are mounted on the bottom surface of the movable plate. A positioning plate is fixedly connected to the moving end of the electric push rod. Several positioning rods are slidably connected to the top surface of the positioning plate. The bottom ends of the positioning rods are welded with a stacking plate for clamping the polyurethane boards. A positioning block is welded to the top surface of the positioning rod. A positioning spring is sleeved on the side of the positioning rod. The two ends of the positioning spring are welded to the positioning plate and the stacking plate, respectively. Two L-shaped positioning frames are welded to the top surface of the positioning plate. The side of the movable plate is slidably connected to the four positioning frames.

[0006] Preferably, a threaded rod is rotatably connected to the inner side wall of the support frame, and the threaded rod is threadedly connected to the threaded plate.

[0007] Preferably, the threaded plate has two limiting plates embedded in the side sliding connection, and both ends of the two limiting plates are welded to the support frame.

[0008] Preferably, both ends of the threaded plate are welded with C-shaped movable frames, and the two movable frames are slidably connected to the support frame on opposite sides. An electric push rod is installed on the top surface of the movable frame.

[0009] Preferably, the moving ends of the two electric push rods are connected to the movable plate by bolts, and several inverted U-shaped limit frames are welded to the top surface of the support frame, with a clamping component provided at the bottom of the limit frames.

[0010] Preferably, the clamping assembly includes a clamping plate and an inverted U-shaped fixing frame, the bottom surface of which is welded to a threaded plate, and the inner sidewall of the fixing frame is slidably connected to the clamping plate.

[0011] Preferably, the side of the abutment plate has two symmetrically arranged fixing plates with an embedded sliding connection. The two fixing plates are welded to the fixing frame on opposite sides, and an electric push rod is installed on the top surface of the fixing frame.

[0012] Preferably, the moving end of the electric push rod three passes through the fixed frame and is connected to the abutment plate. Two abutment columns for pressing against the limiting plate are welded to the bottom surface of the abutment plate, and four support plates arranged in an array are welded to the bottom surface of the support frame.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This stacking device for polyurethane boards is designed to prevent damage to the polyurethane boards during stacking. Thanks to the design of the stacking components, it provides a buffer protection function to prevent excessive vertical compression from damaging the polyurethane boards. Two stacking plates clamp and fix the polyurethane boards, allowing them to move to the designated position for stacking. When a polyurethane board contacts the lower polyurethane board, the positioning rod moves along the path of the positioning plate, and the positioning spring provides elastic thrust to reduce the contact force between the polyurethane boards, thereby preventing damage to the polyurethane boards.

[0015] This stacking device for polyurethane boards involves a threaded plate moving along the threaded path of a threaded rod. During transmission, the lateral position of the stacking assembly is moved, providing conditions for stacking the polyurethane boards. However, there is a threaded gap between the threaded plate and the threaded rod, which can cause the threaded plate to wobble. Thanks to the design of the clamping assembly, it can be clamped and fixed, improving the stacking accuracy of the polyurethane boards. The electric push rod provides power, causing the clamping plate to move along the path of the fixed plate within the cavity of the fixed plate. This ensures that the two clamping posts are tightly pressed against the limiting plate, preventing the threaded plate from wobbling or shifting, and improving the stacking accuracy of the polyurethane boards.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] Please see Figures 1 to 4A stacking device for polyurethane boards is disclosed in this embodiment. The device includes a support frame 1 and a stacking assembly 2 for stacking polyurethane boards. The stacking assembly 2 is disposed within the inner cavity of the support frame 1. The stacking assembly 2 includes a threaded plate 4 and a movable plate 5. Two electric push rods 6 are mounted on the bottom surface of the movable plate 5. The moving ends of the two electric push rods 6 are arranged opposite each other. The fixed ends of the two electric push rods 6 are connected to the movable plate 5 by bolts. A positioning plate 7 is fixedly connected to the moving end of the electric push rod 6. Several positioning rods 9 are slidably connected to the top surface of the positioning plate 7. A stacking plate 12 for clamping the polyurethane boards is welded to the bottom end of the positioning rods 9. A positioning block 10 is welded to the top surface of the positioning rods 9.

[0027] Several positioning blocks 10 are set on the upper part of the positioning plate 7 to prevent the positioning rod 9 from detaching from the positioning plate 7 during movement. The positioning rod 9 is fitted with a positioning spring 11 on its side. The two ends of the positioning spring 11 are welded to the positioning plate 7 and the stacking plate 12 respectively. Two L-shaped positioning frames 8 are welded to the top surface of the positioning plate 7. The side of the movable plate 5 is slidably connected to the four positioning frames 8.

[0028] A threaded rod 14 is rotatably connected to the inner wall of the support frame 1. Both ends of the threaded rod 14 are fixedly connected to connecting shafts. The two connecting shafts are rotatably connected to the support frame 1 via bearings, enabling relative rotation between the threaded rod 14 and the support frame 1. One end of the connecting shaft is connected to the output shaft of a rotary motor via a coupling. The fixed end of the rotary motor is connected to the support frame 1 via bolts. The threaded rod 14 is threadedly connected to the threaded plate 4. Two limiting plates 15 are slidably connected to the side of the threaded plate 4. Sufficient space is reserved between the limiting plates 15 and the positioning block 10 to provide conditions for the vertical movement of the positioning rod 9. Both ends of the two limiting plates 15 are welded to the support frame 1. Both ends of the threaded plate 4 are welded with C-shaped movable frames 3. The inner walls of the two movable frames 3 are arranged opposite each other.

[0029] Both movable frames 3 are slidably connected to the support frame 1 on opposite sides, so that the inner top wall, inner bottom wall and inner side wall of the movable frame 3 are in contact with the support frame 1, which enhances the lateral movement stability of the threaded plate 4. An electric push rod 13 is installed on the top surface of the movable frame 3. The fixed end of the electric push rod 13 is connected to the movable frame 3 by bolts. There is a gap between the moving end of the electric push rod 13 and the support frame 1 to prevent the support frame 1 from scraping the moving end of the electric push rod 13. The fixed end of the electric push rod 13 is connected to the movable frame 3 by bolts. The moving ends of the two electric push rods 13 are connected to the movable plate 5 by bolts. Several inverted U-shaped limit frames 16 are welded to the top surface of the support frame 1. The lower part of the limit frame 16 is provided with a clamping component 18.

[0030] The clamping assembly 18 includes a clamping plate 20 and an inverted U-shaped fixing frame 19. The bottom surface of the fixing frame 19 is welded to the threaded plate 4. The inner side wall of the fixing frame 19 is slidably connected to the clamping plate 20. Two symmetrically arranged fixing plates 21 are slidably connected to the side of the clamping plate 20. The two fixing plates 21 are welded to the fixing frame 19 on opposite sides. An electric push rod 23 is installed on the top surface of the fixing frame 19. The moving end of the electric push rod 23 passes through the fixing frame 19 and is connected to the clamping plate 20. Two clamping posts 22 for pressing against the limiting plate 15 are welded to the bottom surface of the clamping plate 20. Four support plates 17 arranged in an array are welded to the bottom surface of the support frame 1. There is a gap between the top surface of the electric push rod 23 and the inner top wall of the limiting frame 16.

[0031] For palletizing, two electric push rods 6 provide power, which clamps the polyurethane board as the two palletizing plates 12 move adjacently during the transmission process. A rotary motor provides power, which moves the threaded plate 4 along the threaded path of the threaded rod 14. Electric push rod 13 provides power, which moves the polyurethane board to the designated position for palletizing.

[0032] To protect the polyurethane boards, when they are clamped and fixed on top of the polyurethane board, the stacking position cannot be accurately detected, making the polyurethane boards prone to vertical compression damage. Furthermore, the vertical pushing force of the electric push rod 13 cannot be precisely controlled. Thanks to the design of the stacking assembly 2, the polyurethane boards are protected. When the polyurethane boards clamped and fixed by the two stacking plates 12 are placed on the surface of the polyurethane board, the stacking plates 12 drive several positioning rods 9 to move along the path of the positioning plate 7, compressing several positioning springs 11. This causes the positioning springs 11 to provide elastic thrust, stacking the polyurethane boards and preventing damage. The board is damaged by a large vertical force. When two polyurethane boards are in contact with each other, even if the positioning spring 11 vibrates vertically, it will not affect the stacking of the polyurethane boards. When the clamping and fixing of the polyurethane board is released, the positioning spring 11 will elastically reset. By selecting a positioning spring 11 of appropriate size and model, the positioning spring 11 can always be in a compressed state to prevent the positioning spring 11 from elastically shaking and improve the structural stability of the components of the device. Therefore, the positioning spring 11 will not exhibit reciprocating shaking, and there is no need to use damping buffer devices such as dampers. The initial compression strength of the positioning spring 11 can be determined according to the actual use requirements.

[0033] For positioning, the electric push rod 23 provides power, causing the clamping plate 20 to move along the path of the two fixed plates 21 on the inner wall of the fixed frame 19, so that the two clamping posts 22 press against the limiting plate 15, thereby fixing the position of the threaded plate 4 and preventing the threaded plate 4 and the threaded rod 14 from shaking due to the thread gap, thus improving the stacking accuracy of the polyurethane plates. At the same time, two clamping through slots are opened on the top surface of the threaded plate 4 for the clamping posts 22 to pass through.

[0034] Electric actuator 1 (6), electric actuator 2 (13), and electric actuator 3 (23) are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0036] The working principle of this utility model:

[0037] When palletizing, the two electric push rods 6 are activated, and the two palletizing plates 12 clamp and fix the polyurethane plate during the transmission process. The rotary motor is started, and the threaded plate 4 moves along the path of the threaded rod 14. At the same time, the two electric push rods 13 are activated, so that the polyurethane plate moves to the designated position for palletizing.

[0038] When protection is applied, the clamped and fixed polyurethane boards are stacked and subjected to a force from below, causing the stacking plate 12 to move several positioning rods 9 along the path of the positioning plate 7, compressing several positioning springs 11 to provide a buffer protection effect and prevent damage to the polyurethane boards during the stacking process.

[0039] When positioning is performed, the electric push rod 23 is activated. The moving end of the electric push rod 23 drives the clamping plate 20 to be located in the inner cavity of the fixed frame 19 and move along the path of the two fixed plates 21. The two clamping pins 22 pass through the two clamping slots of the threaded plate 4 and are tightly abutted against the two limiting plates 15 to prevent the threaded plate 4 from shaking after the position is fixed.
