Description

Technical Field

[0001] This utility model belongs to the field of wooden pallet production technology, and in particular relates to a binding mechanism for wooden pallet production. Background Technology

[0002] As a core carrier in logistics transportation, the production and assembly of wooden pallets directly determine their load-bearing strength and service life. Modern wooden pallet production has formed a standardized process, requiring precise control from raw material processing to finished product assembly. The binding depth must penetrate the padding blocks and the panel to ensure shear resistance. The nail spacing error is controlled within ±2mm to prevent local stress concentration. Export pallets must undergo ISPM15 fumigation treatment to eliminate the risk of pest transmission. Finished pallets must pass a static load test; the standard 1200mm×1000mm size pallet must bear a load of no less than 1.5 tons.

[0003] Comparing with Chinese Patent No. CN222628111U, a wooden pallet nailing machine is disclosed; it includes a limiting plate, a pneumatic nail gun, and an auxiliary mechanism. The auxiliary mechanism includes a horizontal guide rail, a slide, a vertical guide rail, a drive cylinder, a mounting frame, a side clamping device, and a drive device. During processing, the bottom support wooden strip of the pallet is first placed in the limiting groove of the limiting plate, and the top placement wooden board is placed on top of the support wooden strip and clamped and positioned by the side clamping device. The drive cylinder is activated, driving the mounting frame to move downward, thereby enabling the pneumatic nail gun to move downward. The air source drives the pneumatic nail gun to drive the internal nails to the support wooden strip and the placement wooden board, completing the automatic nailing, thus improving processing efficiency when assembling wooden pallets.

[0004] However, the aforementioned patented wooden pallets need to be manually removed after being assembled, and the horizontal wooden boards also need to be manually placed, which is time-consuming and labor-intensive. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a binding mechanism for wooden pallet production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A binding mechanism for producing wooden pallets includes a frame device for supporting and fixing, a limiting device for positioning wooden strips on the frame device, a translation device for reciprocating movement on the top of the frame device, and an execution device for sequential feeding, nailing, and pushing installed in the middle of the translation device. The frame device includes a worktable with several lifting components evenly distributed in the middle for lifting and binding wooden pallets. The limiting device includes several side limiting plates evenly distributed along the length of the worktable, with two side limiting plates forming a group. Each group of side limiting plates has a positioning plate near the end of the lifting components, and several positioning grooves are evenly distributed near the end of the side limiting plates near the positioning plate. The translation device includes a translation frame with a clearance groove in the middle and power components at both ends of the translation frame. The execution device includes a lifting frame with several pneumatic nail guns evenly distributed on the lifting frame. A feeding box is provided on one side of the pneumatic nail guns, and a push plate is provided on one side of the feeding box.

[0008] Furthermore: four first cylinders are evenly installed at the four corners of the lifting frame, and the main body of the first cylinder is fixedly installed on the translation frame.

[0009] Furthermore: the feeding box is a rectangular box that runs vertically through the top and bottom, and a guide hopper is provided at the top of the feeding box.

[0010] Furthermore, the power assembly includes two symmetrically arranged linear guides, on which linear motors are mounted, and a translation frame is installed between the linear motors.

[0011] Furthermore: The worktable is symmetrically equipped with two side support plates at the front and back, and the linear guide rail is fixedly installed on the side support plates.

[0012] Furthermore: the lifting assembly includes a lifting platform that passes through the worktable from bottom to top, and two second cylinders are symmetrically arranged below the lifting platform. The main body of the second cylinder is fixedly mounted on a fixed bracket, which is located at the bottom of the worktable.

[0013] Furthermore, a discharge ramp is provided at the end of the worktable away from the positioning plate.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] After binding, the entire wooden pallet is lifted by the lifting assembly (second cylinder, lifting platform), freeing the transverse planks from the positioning grooves. Then, a pusher driven by the translation device smoothly moves the pallet until it slides down the unloading ramp, solving the problem of unloading difficulties caused by friction or jamming. This achieves efficient, smooth, and damage-free automated unloading. Through the reciprocating motion of the translation device, the sequential unloading and nailing of all transverse planks is completed automatically and continuously, realizing "one-stop" automated production from raw materials to finished products. This greatly reduces manual intervention and changeover time between processes, significantly improving production efficiency compared to traditional methods. The segmented operation has been significantly improved; the coordinated movement of the actuator and the translation device ensures that the pneumatic nail gun can immediately nail the transverse planks at the intersection point after they fall into the positioning groove. This "nailing upon falling" timing effectively avoids binding errors caused by the displacement of the wooden strips, ensuring the consistency and stability of each wooden pallet structure, and making the product quality stable and reliable. By integrating multiple key processes such as positioning, loading (transverse planks), nailing, and unloading in the wooden pallet production process into one device, the labor intensity of operators has been greatly reduced, while the skill requirements for workers have been reduced, which is conducive to reducing labor costs and management difficulty.

A translation device 3 for reciprocating movement is provided on the top of the frame device 1, and an execution device 4 for sequential feeding, nailing and pushing is installed in the middle of the translation device 3.

[0030] In this embodiment: the frame device 1 includes a workbench 11, with several lifting components evenly distributed in the middle of the workbench 11 for lifting the completed wooden pallets; two side support plates 13 are symmetrically arranged at the front and rear of the workbench 11; the lifting components include a lifting platform 14 that passes through the workbench 11 from bottom to top, and two second cylinders 16 are symmetrically arranged below the lifting platform 14, the main body of the second cylinders 16 being fixedly mounted on a fixed bracket 15, which is located at the bottom of the workbench 11; the workbench 11 is located away from the positioning plate. 22 is provided with a discharge ramp 12 at one end; before binding, the bottom surface of the longitudinal wooden strip is placed on the workbench 11 and the lifting platform 14; during binding, the side support plate 13 supports the linear guide rail 31; after binding, the fixed bracket 15 supports the extension of the second cylinder 16 to push the lifting platform 14 to lift the wooden pallet through the longitudinal wooden strip, so that the transverse wooden board is higher than the positioning groove 23, ensuring that the push plate 46 pushes the wooden pallet along the side limit plate 21 through the transverse wooden board, and finally moves it out of the workbench 11 and slides down to the ground along the discharge ramp 12;

[0031] In this embodiment: the limiting device 2 includes a plurality of side limiting plates 21 evenly distributed along the length of the workbench 11, with each pair of side limiting plates 21 forming a group. Each group of side limiting plates 21 is provided with a positioning plate 22 near the end of the lifting assembly. A plurality of positioning grooves 23 are evenly distributed near the end of the side limiting plates 21 near the positioning plate 22. The longitudinal wooden strip is placed between the side limiting plates 21 and one end of the longitudinal wooden strip is positioned against the positioning plate 22. The positioning grooves 23 are used to position the transverse wooden boards that fall freely in the unloading box 44, so that the transverse wooden boards and the longitudinal wooden strips intersect to form a wooden pallet.

[0032] In this embodiment: the translation device 3 includes a translation frame 33, a clearance groove 34 is provided in the middle of the translation frame 33, and power components are provided at the front and rear ends of the translation frame 33; the power components include two symmetrically arranged linear guide rails 31, a linear motor 32 is installed on the linear guide rails 31, and the translation frame 33 is installed between the linear motors 32; the linear guide rails 31 are fixedly installed on the side support plate 13; the linear motors 32 drive the translation frame 33 to reciprocate along the linear guide rails 31, and sequentially cooperate to complete the material feeding, nailing and pushing, and the clearance groove 34 is used to avoid the material feeding box 44 and the pneumatic nail gun 43;

[0033] In this embodiment: the actuator 4 includes a lifting frame 41, on which several pneumatic nail guns 43 are evenly distributed. A feeding box 44 is provided on one side of the pneumatic nail guns 43, and a push plate 46 is provided on one side of the feeding box 44. Four first cylinders 42 are evenly installed at the four corners of the lifting frame 41, and the main body of the first cylinders 42 is fixedly installed on the translation frame 33. The feeding box 44 is a rectangular box that runs vertically through the top and bottom, and a guide hopper 45 is provided at the top of the feeding box 44. Before binding, the first cylinders 42 extend to push the lifting frame 41, causing the pneumatic nail guns 43 and the feeding box 44 to move downward, so that the bottom surface of the feeding box 44 is close to the top surface of the side limiting plate 21, and then... The horizontal wooden boards are stacked together and placed into the feeding box 44 through the guide hopper 45. During binding, the feeding box 44 and the pneumatic nail gun 43 move along the side limiting plate 21. When they encounter the positioning groove 23, the horizontal wooden boards in the feeding box 44 fall freely into the positioning groove 23 and intersect with the longitudinal wooden strips. Then, when the pneumatic nail gun 43 passes by, it nails the intersection. The above steps are repeated until all the horizontal wooden boards in the feeding box 44 are used up and all the positioning grooves 23 are filled, thus completing the binding of the wooden pallet. After binding, the push plate 46 on the lifting frame 41 pushes the wooden pallet along the side limiting plate 21 through the horizontal wooden boards.

[0034] Working principle: Before binding, the longitudinal wooden strips are placed between the side limiting plates 21, and one end of the longitudinal wooden strip is placed tightly against the positioning plate 22 for positioning. The bottom surface of the longitudinal wooden strip is placed on the workbench 11 and the lifting platform 14. Then, the translation frame 33 supports the extension of the first cylinder 42, pushes the lifting frame 41 to drive the pneumatic nail gun 43 and the feeding box 44 to move down, so that the bottom surface of the feeding box 44 is close to the top surface of the side limiting plate 21. Then, the transverse wooden boards are stacked together and placed into the feeding box 44 through the guide hopper 45.

[0035] During binding, the linear motor 32 drives the translation frame 33 to move along the linear guide rail 31 supported by the side support plate 13, so that the feeding box 44 and the pneumatic nail gun 43 move along the side limiting plate 21. When it encounters the positioning groove 23, the horizontal wooden board in the feeding box 44 first falls freely into the positioning groove 23 and intersects with the longitudinal wooden strip. Then, when the pneumatic nail gun 43 passes by, it nails the intersection. The above steps are carried out until all the horizontal wooden boards in the feeding box 44 are used up and all the positioning grooves 23 are filled, thus completing the binding of the wooden pallet.

[0036] After binding, the fixed bracket 15 supports the extension of the second cylinder 16 to push the lifting platform 14 to lift the wooden pallet through the longitudinal wooden strips, so that the transverse wooden board is higher than the positioning groove 23. At this time, the linear motor 32 drives the translation frame 33 to move in the opposite direction along the linear guide rail 31, so that the push plate 46 on the lifting frame 41 pushes the wooden pallet along the side limit plate 21 through the transverse wooden board, and finally moves it out of the workbench 11 and slides down to the ground along the unloading ramp 12.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
