Description

Technical Field

[0001] This utility model mainly relates to the field of wooden pallet production technology, specifically to a limiting device for wooden pallet binding. Background Technology

[0002] Pallet binding is a crucial step in the production of wooden pallets. To ensure the accuracy and stability of the binding, the pallets need to be secured and fixed in place.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: The National Patent Publication No. CN222539910U discloses a device entitled "A Limiting Device for Binding Wooden Pallets," which includes a horizontal plate, a first support frame, a second support frame, and a baffle. The lower end of the horizontal plate is fixedly connected to the first and second support frames for support. The upper side of the horizontal plate is fixedly connected to a baffle and a center plate. The two ends of the baffle and the center plate are connected by a vertical plate positioning frame. A center groove is opened at the lower end of the center plate, and a positioning rod is fixedly connected to the inner wall of the upper end of the center groove. A storage box is welded and fixed to one side of the center plate, and the inside of the storage box contains boards. A feeding mechanism is installed at one end of the positioning rod. In this utility model, during the production of wooden pallets, the horizontally placed boards can be fed in a concentrated manner at one time, which has a high feeding efficiency and low labor input, reducing the labor intensity of production. At the same time, the feeding method is faster, which can further improve the efficiency of wooden pallet production.

[0004] Among the aforementioned mechanisms, the limiting device has a fixed structure and can only be adapted to wooden pallets of specific specifications, making it less suitable for pallets of different sizes. Furthermore, the limiting device uses rigid contact fixing, which can easily damage the wooden pallet during the binding process, affecting the production quality of the pallet.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model: This utility model provides a limiting device for binding wooden pallets to solve the technical problems existing in the background art.

[0007] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: a limiting device for binding wooden pallets, comprising a working board, a bottom support frame, and a mounting frame. The bottom support frame is fixedly installed below the working board, and the mounting frame is fixedly installed above the working board. The working board has a synchronous limiting component and an independent limiting component on its top. The synchronous limiting component includes four synchronously movable limiting plates, and the independent limiting component includes four independently movable adjustable limiting plates. The surface of the adjustable limiting plates is connected to an airbag via a connecting rod, and the airbag is in flexible contact with the side of the board.

[0008] Furthermore, the synchronous limiting component includes a hydraulic cylinder fixedly installed on the top of the bottom support frame. The actuating end of the hydraulic cylinder is connected to a connecting plate. A deformable template is provided in the middle of the bottom wall of the working plate. Movable plates are provided on all four sides of the deformable template. The connecting plate is fixedly connected to one of the movable plates. A first connecting rod is rotatably connected to each of the four corners of the bottom wall of the deformable template. A second connecting rod is rotatably connected to the bottom wall of the movable plate. The ends of the first connecting rod and the second connecting rod are hinged. A protrusion is provided on the top of the movable plate. A sliding groove is opened inside the working plate corresponding to the position of the protrusion. The protrusion slides through the interior of the sliding groove. The synchronous limiting plate is fixedly installed on the top of the protrusion.

[0009] Furthermore, the independent limiting component includes a screw that passes laterally through the interior of the mounting frame. One end of the screw is fitted with a nut, and the other end of the screw passes laterally through the interior of the synchronous limiting plate. The adjustable limiting plate is connected to the other end of the screw via a rotating shaft.

[0010] Furthermore, the screw slides laterally inside the mounting frame, and the synchronous limiting plate has a threaded hole inside, with the outer wall of the screw threadedly connected to the inner wall of the threaded hole.

[0011] Furthermore, multiple airbags are provided, and multiple airbags on one side of the adjustable limiting plate are interconnected through air delivery hoses, and one of the airbags can be connected to an air pressure control system.

[0012] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model is reasonably designed. Through the arrangement and cooperation between the hydraulic cylinder, connecting plate, deformable template, movable plate, first connecting rod, second connecting rod, protrusion and slide groove, the position of the synchronous limiting plate can be adjusted synchronously. It is suitable for limiting square plates. With the setting of screw, nut and adjustable limiting plate, the position of the adjustable limiting plate can be adjusted independently, which is suitable for limiting rectangular plates. Both limiting methods are compatible with plates of different sizes, reducing equipment replacement and expanding the application scenarios of the equipment. By using airbags and a pneumatic control system, a flexible contact method is employed to secure the boards, preventing damage from impact forces during binding. This provides better protection, especially for thinner boards, during binding.

[0013] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0020] See attached document Figure 1-4 A limiting device for binding wooden pallets includes a working board 1, a bottom support frame 2, and a mounting frame 3. The bottom support frame 2 is fixedly installed below the working board 1, and the mounting frame 3 is fixedly installed above the working board 1. The top of the working board 1 is provided with a synchronous limiting component and an independent limiting component. The synchronous limiting component includes four synchronously movable limiting plates 4, and the independent limiting component includes four independently movable adjustable limiting plates 5. The surface of the adjustable limiting plates 5 is connected to an airbag 6 via a connecting rod. The airbag 6 flexibly contacts the side of the board and can be adjusted according to the size of the binding pallet board. The flexible contact improves the protective effect during binding.

[0021] In this embodiment, the synchronous limiting component includes a hydraulic cylinder 7 fixedly installed on the top of the bottom support frame 2. The actuating end of the hydraulic cylinder 7 is connected to a connecting plate 8. A deformable template 9 is provided in the middle of the bottom wall of the working plate 1. Movable plates 10 are provided on all four sides of the deformable template 9. The connecting plate 8 is fixedly connected to one of the movable plates 10. A first connecting rod 11 is rotatably connected to each of the four corners of the bottom wall of the deformable template 9. A second connecting rod 12 is rotatably connected to the bottom wall of the movable plate 10. The ends of the first connecting rod 11 and the second connecting rod 12 are hinged. A protrusion 13 is provided on the top of the movable plate 10. A groove 100 is opened inside the working plate 1 at the position corresponding to the protrusion 13. The protrusion 13 slides through the interior of the groove 100. The synchronous limiting plate 4 is fixedly installed on the top of the protrusion 13.

[0022] It should be noted that when the length and width of the bound boards are equal, the hydraulic cylinder 7 is activated, causing its actuator rod to extend outward, thereby pushing the connecting plate 8 to move. The connecting plate 8 drives one of the movable plates 10 to move. The movement of the movable plate 10 drives the first connecting rod 11 and the second connecting rod 12 to rotate. The second connecting rod 12 drives the other three movable plates 10 to move synchronously. The four movable plates 10 move synchronously, causing the protrusion 13 to move synchronously along the inside of the slide groove 100, thereby adjusting the position of the synchronous limit plate 4.

[0023] In this embodiment, the independent limiting component includes a screw 14 that passes laterally through the interior of the mounting frame 3. One end of the screw 14 is fitted with a nut 15, and the other end of the screw 14 passes laterally through the interior of the synchronous limiting plate 4. The adjustable limiting plate 5 is connected to the other end of the screw 14 via a rotating shaft. The screw 14 slides laterally inside the mounting frame 3. The synchronous limiting plate 4 has a threaded hole inside, and the outer wall of the screw 14 is threadedly connected to the inner wall of the threaded hole.

[0024] It should be noted that when the length and width of the bound boards are not equal, only the position of the adjustable limit plate 5 is adjusted. By rotating the nut 15, the screw 14 is moved, which causes the adjustable limit plate 5 to move. The boards with different lengths and widths can be limited and fixed by independently adjusting the adjustable limit plate 5.

[0025] In this embodiment, multiple airbags 6 are provided. Multiple airbags 6 on one side of the adjustable limiting plate 5 are interconnected through air delivery hoses 16, and one of the airbags 6 can be connected to the air pressure control system.

[0026] It should be noted that the airbag 6 is inflated by the air pressure control system. The airbag 6 begins to expand, and under the action of the air supply hose 16, the airbag 6 connected below also begins to expand. The expansion of the airbag 6 is used to achieve flexible contact and limit with the side of the board, avoiding damage to the board caused by the impact force during binding.

[0027] The working principle of this utility model is as follows: When using this device, first place the pallet material to be bound on top of the working plate 1. When the length and width of the bound material are equal, activate the hydraulic cylinder 7 to extend its actuator rod outward, thereby pushing the connecting plate 8 to move. The connecting plate 8 drives one of the movable plates 10 to move. The movement of the movable plate 10 drives the first connecting rod 11 and the second connecting rod 12 to rotate. The second connecting rod 12 drives the other three movable plates 10 to move synchronously. The synchronous movement of the four movable plates 10 causes the protrusion 13 to move synchronously along the inside of the slide groove 100, thereby adjusting the position of the synchronous limiting plate 4. When the length and width of the bound material are unequal, only... Adjust the position of the adjustable limit plate 5 by rotating the nut 15 to move the screw 14, thus moving the adjustable limit plate 5. The adjustable limit plate 5 can be adjusted independently to limit and fix plates of different lengths and widths. After initially adjusting to a suitable position, the air pressure control system inflates the airbag 6. The airbag 6 begins to expand, and under the action of the air supply hose 16, the airbag 6 connected below also begins to expand. The expansion of the airbag 6 is used to achieve flexible contact and limitation with the side of the plate. After it is completely fixed, the plate can be nailed with a pneumatic nail gun. After nailing, the airbag 6 is deflated, and the tray can be removed.

[0028] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
