Description

Technical Field

[0001] This utility model relates to the field of wooden pallet production technology, specifically a wooden pallet arc angle cutting device. Background Technology

[0002] Wooden pallets are horizontal platform devices used for the assembly, stacking, handling and transportation of goods and products as unit loads, facilitating the loading, unloading and handling of unit materials and small quantities of materials.

[0003] To improve the safety of wooden pallets, it is necessary to round the four corners of the pallet when using them. This requires a rounded corner cutting device to cut the corners of the pallet. The existing method of processing the rounded corners of wooden pallets is to manually cut the corners of the pallet with a handheld cutting machine. This method is not only inefficient, but also labor-intensive and inconvenient for workers. Therefore, we propose a wooden pallet rounded corner cutting device to solve the problem.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention involves placing one corner of a wooden pallet on a base and securing it using a pallet-limiting mechanism. A second motor then drives a milling cutter to rotate, causing a first hydraulic rod to lower the cutter via a top frame. Simultaneously, a drive mechanism rotates a rotating shaft, causing the milling cutter to rotate around the shaft within a radius of ±45°. This process completes the arc-angle cutting of the wooden pallet. This arc-angle cutting device replaces manual processing of the pallet's arc angles, effectively improving cutting efficiency and reducing labor intensity.

[0013] This invention, when it is necessary to adjust the rotation radius of the milling cutter, uses the rotation of an adjusting screw to move the adjusting frame via a threaded connection with the fixed frame. This causes the adjusting frame and the fixed frame to move closer or further apart, thereby adjusting the rotation radius of the milling cutter. Simultaneously, a third motor drives a lead screw to rotate, which in turn moves a slider via a threaded connection. The slider then moves the milling cutter laterally via a sliding seat and a top frame, thereby adjusting the rotation center position of the milling cutter. Through this adjustment mechanism, the rotation radius and center of the milling cutter can be adjusted, enabling the processing of arc angles of different curvatures on wooden pallets, effectively improving the applicability of the arc angle cutting device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 3 This utility model provides a technical solution: a wooden pallet arc-angle cutting device, including a base 1, a sliding seat 2 slidably disposed on the top of one side of the base 1, and a first hydraulic rod 3 installed on the top of the sliding seat 2, wherein... The telescopic end of the first hydraulic rod 3 is equipped with a top frame 4. The side of the top frame 4 away from the first hydraulic rod 3 is rotatably connected to a rotating shaft 8. The bottom end of the rotating shaft 8 is fixedly connected to a fixing frame 9. An adjusting frame 10 is provided on the side of the fixing frame 9 close to the first hydraulic rod 3. The rotating shaft 8 is driven to rotate by the drive mechanism. The second motor 14 is installed on the adjustment frame 10. The end of the shaft of the second motor 14 is equipped with a milling cutter 15. The milling cutter 15 is used to process the arc corners of wooden pallets with different curvatures through the adjustment mechanism. A wooden pallet limiting mechanism is provided on the top side of the base 1. One corner of the wooden pallet is placed on the base 1 and fixed by the pallet limiting mechanism. Then, the second motor 14 drives the milling cutter 15 to rotate, causing the first hydraulic rod 3 to drive the milling cutter 15 to fall through the top frame 4. At the same time, the drive mechanism drives the rotating shaft 8 to rotate, which in turn causes the milling cutter 15 to rotate around the rotating shaft 8. The rotation of the milling cutter 15 around the rotating shaft 8 is limited to ±45°, thus completing the arc corner cutting of the wooden pallet. This arc corner cutting device can replace manual processing of the arc corner of the wooden pallet, thereby effectively improving the efficiency of arc corner cutting of the wooden pallet and reducing the labor intensity of the workers.

[0018] Please see Figures 1 to 3The sliding seat 2 is symmetrically and fixedly connected to the top of both sides near the first hydraulic rod 3 with support rods 5. The top of the support rod 5 is provided with a guide groove 6. The top frame 4 is fixedly connected to the bottom of the guide groove 6 with a guide rod 7. The guide rod 7 is a cylinder and the outer diameter of the guide rod 7 matches the inner diameter of the guide groove 6. When the top frame 4 is driven to rise and fall by the first hydraulic rod 3, the top frame 4 drives the guide rod 7 to move in the guide groove 6. The guide structure formed by the guide rod 7 and the guide groove 6 can guide the rise and fall of the top frame 4.

[0019] Please see Figures 1 to 3 The drive mechanism includes a first motor 11, which is mounted on the top of one side of the top frame 4. A first reversing gear 12 is mounted on the shaft end of the first motor 11 corresponding to the shaft end of the rotating shaft 8, and a second reversing gear 13 is mounted on the shaft end of the rotating shaft 8 corresponding to the first reversing gear 12. The adjustment mechanism includes an adjusting screw 16, which is threadedly connected to the middle of the fixed frame 9. One end of the adjusting screw 16 is rotatably connected to the adjustment frame 10. Guide rod grooves 17 are symmetrically passed through both sides of the fixed frame 9. A guide rod 18 is fixedly connected to the side of the adjustment frame 10 near the guide rod groove 17. A sliding groove 19 is opened on the top of the base 1 corresponding to the sliding seat 2. A slider 20 is fixedly connected to the bottom of the sliding groove 19 corresponding to the sliding seat 2. A lead screw 21 is rotatably connected inside the sliding groove 19. A third motor 22 is mounted on one end of the base 1 corresponding to the sliding groove 19. The shaft end of the third motor 22 is fixedly connected to the lead screw 21. When the first motor 11 is working, it drives the first reversing gear. When wheel 12 rotates, the first reversing gear 12 meshes with the second reversing gear 13, causing the second reversing gear 13 to drive the rotating shaft 8 to rotate, which in turn drives the milling cutter 15 to rotate. When it is necessary to adjust the rotation radius of the milling cutter 15, the rotation of the adjusting screw 16 causes the adjusting screw 16 to move through the threaded connection with the fixed frame 9, so that the adjusting frame 10 and the fixed frame 9 move closer or further apart, thereby adjusting the rotation radius of the milling cutter 15. At the same time, the third motor 22 drives the lead screw 21 to rotate, causing the lead screw 21 to move through the threaded connection with the slider 20, so that the slider 20 drives the milling cutter 15 to slide laterally through the sliding seat 2 and the top frame 4, thereby adjusting the rotation center position of the milling cutter 15. Through this adjustment mechanism, the rotation radius and center of the milling cutter 15 can be adjusted, thereby enabling the processing of arc angles of different curvatures on wooden pallets, effectively improving the applicability of the arc angle cutting device.

[0020] Please see Figures 1 to 3 The limiting mechanism includes a limiting frame 23. The limiting frame 23 is symmetrically and fixedly connected to the top of the base 1 on the side away from the sliding seat 2. The top of the limiting frame 23 is fixedly connected to the mounting frame 24. The top of the mounting frame 24 is equipped with a second hydraulic rod 25. The telescopic end of the second hydraulic rod 25 located below the mounting frame 24 is equipped with a pressure plate 26. The limiting frames 23 are distributed in a figure-eight shape, and the included angle between the limiting frames 23 is 90°.

[0021] Working principle: This arc-angle cutting device for wooden pallets places one corner of the wooden pallet on the base 1 and fixes it through the pallet limiting mechanism. Then, the second motor 14 drives the milling cutter 15 to rotate, causing the first hydraulic rod 3 to drive the milling cutter 15 to fall through the top frame 4. At the same time, the drive mechanism drives the rotating shaft 8 to rotate, thereby causing the milling cutter 15 to rotate around the rotating shaft 8 as the center. The rotation of the milling cutter 15 around the rotating shaft 8 is limited to ±45°, thus completing the arc-angle cutting of the wooden pallet. This arc-angle cutting device can replace manual processing of the arc-angle of the wooden pallet, thereby effectively improving the efficiency of arc-angle cutting of wooden pallets and reducing the labor intensity of workers. When the first hydraulic rod 3 drives the top frame 4 to rise and fall, the top frame 4 drives the guide rod 7 to move in the guide groove 6. The guide structure formed by the guide rod 7 and the guide groove 6 can guide the rise and fall of the top frame 4. When the first motor 11 is working, it drives the first reversing gear 12 to rotate. The first reversing gear 12 drives the second reversing gear 13 to rotate through meshing, causing the second reversing gear 13 to drive the rotating shaft 8 to rotate, which in turn drives the milling cutter 15 to rotate. When it is necessary to adjust the rotation radius of the milling cutter 15, the rotation of the adjusting screw 16 causes the adjusting screw 16 to drive the adjusting frame 10 to move through the threaded connection with the fixed frame 9, so that the adjusting frame 10 and the fixed frame 9 move closer or further apart, thereby adjusting the rotation radius of the milling cutter 15. At the same time, the third motor 22 drives the lead screw 21 to rotate, causing the lead screw 21 to drive the slider 20 to move through the threaded connection, so that the slider 20 drives the milling cutter 15 to slide laterally through the sliding seat 2 and the top frame 4, thereby adjusting the rotation center position of the milling cutter 15. Through this adjustment mechanism, the rotation radius and center of the milling cutter 15 can be adjusted, thereby enabling the processing of arc angles of different curvatures on wooden pallets, effectively improving the applicability of the arc angle cutting device.
