[0002] Wooden pallets are the most widely used pallets today. Pallets are horizontal platforms used for the collection, stacking, handling, and transportation of unit loads of goods and products. They are typically made of wood, metal, or fiberboard, and are convenient for loading and unloading, and for transporting unit loads and small quantities of goods.

[0003] Most of the existing wooden pallets are rectangular in shape. After grinding the shorter side, when the longer side needs to be grinded, the position of the grinding roller needs to be manually adjusted. This requires the staff to frequently adjust the position of the grinding roller, which increases the labor intensity of the staff and makes it difficult to control the position of the grinding roller.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0028] Furthermore, a first connecting groove is provided on the outer wall of the placement plate 312, and the inner wall of the first connecting groove is connected to the inner wall of the slide groove. The outer wall of the pull rod 318 is slidably provided in the first connecting groove.

The outer wall of the connecting rod 319 is slidably provided on the inner wall of the second connecting groove. In this way, the slides 316 at all places can be connected, so that the slides 316 can be directly driven to move by the pull rod 318 to facilitate placement and disassembly.

[0029] Furthermore, there are four slides 316, which are symmetrically distributed in groups of two at the bottom end of the limit plate 317 and fit snugly against the inner wall of the slide groove. This allows the limit plate 317 to be evenly supported on both sides, thereby improving the stability of the limit plate 317 during the limiting and fixing process.

[0030] Furthermore, there are two sliding columns 3113, which are symmetrically distributed at the upper and lower ends of the outer wall of the grinding roller 3114 and fit snugly with the inner wall of the sliding sleeve 3111. In this way, the upper and lower ends can support the grinding roller 3114, thereby improving the stability of the grinding roller 3114 during the grinding process.

[0031] The moving mechanism 32 includes a support plate 321 fixedly connected to the outer wall of the base plate 1, a second motor 322 fixedly connected to the top of the support plate 321, a rotating column 323 fixedly connected to the output end of the second motor 322, a cam groove 324 is provided on the outer wall of the rotating column 323, a connecting block 325 is slidingly provided on the inner wall of the cam groove 324, the connecting block 325 is fixedly connected to the outer wall of the sliding sleeve 3111 at one end away from the inner wall of the cam groove 324, a limiting groove 326 is provided on the inner outer wall of the support frame 2, a limiting slider 327 is slidingly provided on the inner wall of the limiting groove 326, and the limiting slider 327 is fixedly connected to the outer wall of the connecting plate 3110 at one end away from the limiting groove 326.

[0033] Furthermore, the outer wall of the limiting groove 326 fits snugly with the outer wall of the limiting slider 327 , thereby ensuring the stability of the limiting slider 327 during the sliding process on the inner wall of the limiting groove 326 .

[0034] The implementation principle of the edge grinding mechanism for a wooden pallet in this embodiment is as follows: first, the pull rods 318 on both sides are moved closer to the middle, which will drive the slide plate 316 to move on the outer wall of the slide rod 314. At the same time, during the movement of the slide plate 316, the first spring 315 will be squeezed. As the slide plate 316 moves, the two side limit plates 317 at the top can be driven to move closer to each other. Then, the wooden pallet can be placed on the placement plate 312. After placement, the pull rod 318 can be released, and the rebound effect of the first spring 315 can drive the two side limit plates 317 to reset and move to the left and right sides. In this way, the two side outer walls of the limit plates 317 will contact and squeeze the inner wall of the wooden pallet, thereby forming a limit and fixing effect on the wooden pallet. When the edge grinding on one side is completed After grinding, the first motor 311 is started to drive the placement plate 312 to rotate. The rotation of the placement plate 312 can drive the wooden pallet to rotate. When the longer side of the wooden pallet rotates to the position of the grinding roller 3114, the grinding roller 3114 will be squeezed. The squeezed grinding roller 3114 will drive the sliding column 3113 to move on the inner wall of the sliding sleeve 3111. At the same time, the second spring 3112 is squeezed during the movement. After the rotation is completed, the rebound effect of the second spring 3112 can push the grinding roller 3114 in the opposite direction to fit tightly against the outer wall of the wooden pallet, and the outer wall of the wooden pallet can be polished by the grinding roller 3114. In this way, there is no need for staff to adjust the position of the wooden pallet and the grinding roller 3114 during the whole process, thereby improving the grinding efficiency.

[0035] During the grinding process, the second motor 322 is started synchronously, and its output end will drive the rotating column 323 to rotate. The rotation of the rotating column 323 can drive the cam groove 324 on its outer wall to rotate, and the rotation of the cam groove 324 can drive the connecting block 325 to move back and forth left and right. In this way, the connecting block 325 can drive the grinding roller 3114 to move back and forth left and right, and the limiting slide groove 326 and the limiting slider 327 can support the grinding roller 3114. In this way, the grinding roller 3114 can reciprocate and grind the outer edge of the wooden pallet, thereby improving the grinding effect.
