Description

Technical Field

[0001] This utility model belongs to the field of plywood processing technology, specifically a cold press for plywood processing. Background Technology

[0002] Cold pressing is an essential step in plywood production. Currently, the industry commonly uses forklifts to place plywood to be stacked on the work platform. However, the sides of the stacked plywood transferred by forklifts are not always perfectly aligned, resulting in some plywood near the edges not receiving effective pressure. During cold pressing, uneven force can cause the plywood to shift, leading to misalignment between multiple layers and severely impacting the final plywood quality. Furthermore, the forklift slots on the workbench disrupt the flatness of the table, causing inconsistent pressure on different parts of the plywood. This results in insufficient compaction in some areas, inadequate glue adhesion, and even localized areas of plywood sinking into the slots, significantly reducing the surface flatness of the plywood and further lowering product quality and yield. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a cold press for plywood processing, so as to at least partially solve the problems mentioned in the background art.

[0004] This utility model provides the following technical solution: A cold press for plywood processing, comprising:

[0005] The workbench has a forklift slot;

[0006] A filler support plate is configured to slide and rise within the forklift bay.

[0007] Two sets of symmetrically arranged side baffles are configured to move relative to each other along the length of the plywood, and sliding grooves are provided on the side baffles.

[0008] The sorting mechanism is located within the sliding groove;

[0009] Two sets of symmetrically arranged movable plates are connected to a sorting mechanism, and the two sets of movable plates are driven by the sorting mechanism to move relative to each other along the width direction of the plywood.

[0010] Furthermore, the workbench is provided with a filling drive cavity, and the filling drive cavity is provided with a filling mechanism. The filling mechanism includes a filling motor, a filling drive shaft, and a filling assembly. The filling motor is fixedly mounted on the top wall of the filling drive cavity, and a mounting plate is fixedly mounted inside the filling drive cavity. The filling drive shaft is rotatably mounted on the mounting plate. A pulley is fixedly mounted on the output end of the filling motor and the filling drive shaft, and a synchronous belt is fitted on the pulley. Both ends of the filling drive shaft are provided with driving bevel gears. The filling assembly is provided with two sets of gears at both ends of the filling drive shaft. The filling assembly is provided with driven bevel gears, and the driven bevel gears mesh with the driving bevel gears. The filling support plate is connected to the filling assembly.

[0011] Furthermore, the filling assembly includes a threaded cylinder and a filling threaded rod. The threaded cylinder is rotatably mounted on the bottom wall of the filling drive cavity. The driven bevel gear is fixedly mounted on the threaded cylinder. The filling threaded rod is connected to the threaded cylinder via threads. The filling support plate is connected to the filling threaded rod.

[0012] Furthermore, two sets of sliding grooves are provided on the upper and lower parts of the side baffle. The sorting mechanism includes a sorting motor, a bidirectional screw, and an anti-rotation rod. The sorting motor is fixedly mounted on the side baffle. The bidirectional screw is rotatably mounted in one set of sliding grooves. One end of the bidirectional screw is connected to the output end of the sorting motor. The anti-rotation rod is fixedly mounted in the other set of sliding grooves. One end of the moving plate is connected to the bidirectional screw through a threaded block. The other end of the moving plate is slidably mounted on the anti-rotation rod through a slider.

[0013] Furthermore, the workbench is provided with a support frame, and the support frame is provided with a push-pull cylinder, and the side baffle is connected to the push-pull cylinder.

[0014] Furthermore, the support frame is equipped with a cold-pressing cylinder, and the free end of the cold-pressing cylinder is equipped with a cold-pressing plate.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] 1. The lifting structure of the filling support plate in the forklift slot allows it to be lowered during forklift loading and unloading without affecting operation. After loading, it rises to be flush with the worktable, filling the unevenness of the worktable caused by the forklift slot. This ensures that the plywood is subjected to uniform force during cold pressing, avoiding problems such as insufficient compaction, inadequate glue bonding, and localized plywood sinking into the slot, which affects the surface flatness. This effectively improves the quality of plywood cold pressing.

[0017] 2. By using side baffles and moving plates to limit the plywood from all four sides, the positional stability of the plywood during cold pressing is greatly improved, preventing displacement due to uneven force, ensuring precise alignment between multiple layers of plywood, and improving product quality.

Detailed Implementation

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

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] See Figure 1 and Figure 4 This embodiment provides a cold press for plywood processing, comprising:

[0027] Workbench 1, on which a forklift slot 2 is provided;

[0028] The filling support plate 3 is configured to slide and rise within the forklift slot 2. When the forklift loads the plywood, the filling support plate 3 is in a lowered state within the forklift slot 2. After the forklift finishes loading, the forklift arm moves out of the forklift slot 2, and the filling support plate 3 moves up to its upper surface to contact the plywood. At this time, the upper surface of the filling support plate 3 is flush with the upper surface of the workbench 1, ensuring the uniformity of stress on each part of the plywood during cold pressing.

[0029] Two sets of symmetrically arranged side baffles 4 are configured to move relative to each other along the length of the plywood. The two sets of side baffles 4 cooperate to limit the plywood from the length of the plywood. A sliding groove 5 is provided on the side baffles 4.

[0030] The sorting mechanism is located within the sliding groove 5;

[0031] Two sets of symmetrically arranged movable plates 6 are connected to the sorting mechanism. The two sets of movable plates 6 are driven by the sorting mechanism to move relative to each other along the width direction of the plywood. The two sets of movable plates 6 limit the plywood from the width direction of the plywood.

[0032] During operation, the side baffle 4 and the movable plate 6 work together to limit the plywood from all four sides, improving the positional stability and stress uniformity of the plywood during cold pressing. Furthermore, when loading and unloading the plywood, the push-pull plate rises relative to the worktable 1 to prevent the push-pull plate from affecting the forklift's loading and unloading of the plywood.

[0033] Specifically, see Figure 2 In this embodiment, the workbench 1 is provided with a filling drive cavity 7, and the filling drive cavity 7 is provided with a filling mechanism. The filling mechanism includes a filling motor 8, a filling drive shaft 9, and a filling assembly. The filling motor 8 is fixedly mounted on the top wall of the filling drive cavity 7. A mounting plate is fixedly mounted inside the filling drive cavity 7. The filling drive shaft 9 is rotatably mounted on the mounting plate. A pulley is fixedly mounted on the output end of the filling motor 8 and the filling drive shaft 9. A synchronous belt 10 is sleeved on the pulley. The filling motor 8 drives the filling drive shaft 9 to rotate through the synchronous belt 10. Both ends of the filling drive shaft 9 are provided with driving bevel gears 11. Two sets of filling assemblies are provided at both ends of the filling drive shaft 9. The filling assembly is provided with driven bevel gears 12. The driven bevel gears 12 mesh with the driving bevel gears 11. The filling support plate 3 is connected to the filling assembly. During operation, the filling drive shaft 9 drives the filling assembly to move the filling support plate 3 up and down in the forklift slot 2.

[0034] Specifically, see Figure 2 and Figure 3 In this embodiment, the filling assembly includes a threaded cylinder 13 and a filling threaded rod 14. The threaded cylinder 13 is rotatably mounted on the bottom wall of the filling drive cavity 7. The driven bevel gear 12 is fixedly mounted on the threaded cylinder 13. The filling threaded rod 14 is connected to the threaded cylinder 13 by threads. The filling support plate 3 is connected to the filling threaded rod 14.

[0035] It should be noted that a guide assembly is also required between the filling support plate 3 and the bottom wall of the filling drive cavity 7. This guide assembly ensures that the filling support plate 3 can stably rise and fall vertically when driven by the filling screw. The structure of the guide assembly is a common technique in this field and is therefore not shown in detail in the accompanying drawings. For example, in this embodiment, the guide assembly includes a guide sleeve and a guide slide rod. The guide sleeve is connected to the bottom wall of the filling drive cavity 7, and the guide slide rod is fixedly connected to the filling support plate 3. When the filling support plate 3 rises and falls, the guide slide rod slides within the guide sleeve accordingly.

[0036] During operation, the filling drive shaft 9 drives the threaded cylinder 13 to rotate, and the threaded cylinder 13 drives the filling threaded rod 14 to move the filling support plate 3 in a corresponding lifting and lowering motion. In this embodiment, the thread direction of the filling threaded rod 14 of the two sets of filling components is adapted to the meshing transmission direction of the driving bevel gear 11 and the driven bevel gear 12, ensuring that the two sets of filling support plates 3 can move in the same direction.

[0037] Specifically, see Figure 1 and Figure 4 In this embodiment, two sets of sliding grooves 5 are provided on the upper and lower parts of the side baffle 4. The sorting mechanism includes a sorting motor 15, a bidirectional screw 16, and an anti-rotation sliding rod 17. The sorting motor 15 is fixedly mounted on the side baffle 4. The bidirectional screw 16 is rotatably mounted in one set of sliding grooves 5. One end of the bidirectional screw 16 is connected to the output end of the sorting motor 15. The anti-rotation sliding rod 17 is fixedly mounted in the other set of sliding grooves 5. One end of the moving plate 6 is connected to the bidirectional screw 16 through a threaded block 18. The other end of the moving plate 6 is slidably mounted on the anti-rotation sliding rod 17 through a slider 19.

[0038] During operation, driven by the tidying motor 15, the two sets of moving plates 6 can be driven from the width direction of the plywood to limit the tidying of the plywood by the drive of the bidirectional screw 16 and the guide of the anti-rotation slip rod 17.

[0039] Specifically, see Figure 1 In this embodiment, the workbench 1 is provided with a support frame 20, and the support frame 20 is provided with a push-pull cylinder 21. The side baffle 4 is connected to the push-pull cylinder 21. Under the extension and retraction action of the push-pull cylinder 21, the side baffle 4 is driven to adjust its position relative to the plywood in the length direction of the plywood. The support frame 20 is provided with a cold pressing cylinder 22, and the free end of the cold pressing cylinder 22 is provided with a cold pressing plate 23. The cold pressing plate 23 may also be connected with a guide component to ensure that the cold pressing plate 23 can be stably and vertically raised and lowered.

[0040] The specific method of using a cold press for plywood processing provided in this embodiment is as follows:

[0041] 1. First, the stacked plywood is placed on the workbench 1 by a forklift. After the plywood is placed, the forklift arm moves out of the forklift slot 2. The filling motor 8 is started to rotate forward. Under the action of the synchronous belt 10, the filling drive shaft 9 is driven to rotate. The filling drive shaft 9 drives the active bevel gear 11 to rotate. Through the meshing of the active bevel gear 11 and the driven bevel gear 12, the threaded cylinder 13 is driven to rotate. Under the guidance of the guide assembly and the drive of the threaded cylinder 13 on the filling screw, the filling support plate 3 can be driven to rise. The upper surface of the filling support plate 3 is flush with the upper surface of the workbench 1.

[0042] 2. Start the second push-pull cylinder 21. The second push-pull cylinder 21 drives the side baffle 4 to approach the plywood from the length direction. The two sets of side baffles 4 tidy up and limit the plywood from both sides of the plywood length. Start the tidying motor 15. The tidying motor 15 drives the bidirectional screw 16 to rotate. Under the drive of the bidirectional screw 16 and the guidance of the anti-rotation slip rod 17, the two sets of moving plates 6 are driven to move. The two sets of moving plates 6 tidy up and limit the plywood from both sides of the plywood width.

[0043] 3. Start the cold pressing cylinder 22 to drive the cold pressing plate 23 to cold press the plywood.
