[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The logistics pallet positioning device, through the positioning components, can realize that when it is necessary to place the goods through the pallet body for transportation, the goods are placed on the placement table, and the placement table can be moved downward under the weight pressure of the goods. During the movement of the placement table, the rack is driven to move, and the rack drives the gear to rotate. The supporting column, the clamping plate and the limit plate can be driven to rotate through the rotating rod under the action of the gear, so that the supporting column and the clamping plate are on the left and right sides of the goods, and when the clamping plate contacts the goods, the first spring and the second spring are deformed, and the goods can be fixed under the action of the clamping plate. At the same time, the goods can be fixed according to the The position of the splint can be automatically adjusted according to the amount of goods, so that the splint is in a stable state and the goods are fixed at the same time, and the rectangular frame can be pulled according to the stacking height of the goods to drive the limit plate to move, and the telescopic rod and the third spring can be deformed, and the top of the goods can be further positioned by the limit plate, so that the goods are in a stable state on the top of the placement table, and the support column and the rotating block are fixed by a fixing bolt, so as to facilitate the installation and disassembly of the support column. During the movement of the placement table, the extrusion block will be driven to move, and a linkage effect will be achieved between the limit assembly, so that the limit plate is limited by the insertion rod.

[0017] 2. The logistics pallet positioning device can realize, through the set limit assembly, that when the goods are placed on the pallet body for transportation, the goods are placed on the top of the placing table, the placing table moves downward under the pressure of the weight, and the support column and the clamping plate rotate under the action of the gear and the rack. When the goods are fixed on the left and right sides of the goods, the extrusion block is driven to move by the placing table, and the inclined block is driven to move by the extrusion block, and the connecting rod, the moving plate and the insertion rod are driven to move under the action of the inclined block, so that the insertion rod is inserted into the limit plate, and when the placing table moves downward and contacts with the top of the pallet body, and at the same time, the support column and the clamping plate are rotated under the action of the gear and the rack, the insertion rod can be synchronously inserted into the limit plate, and the limit plate can be limited under the action of the insertion rod. The limit plate limits the rotating rod and the gear to prevent the gear from rotating due to external factors when the goods are positioned under the action of the support column and the splint, thereby affecting the stability of the support column and the splint, and can achieve a linkage effect with the positioning component. The limit can ensure that the support column and the splint are in a stable state. When the placement table moves, it will drive the extrusion block to move. When it moves to a certain position, it will squeeze the extrusion block, so that the extrusion block drives the connecting rod, the moving plate and the insertion rod to move, and the fourth spring is deformed. When the support column and the splint complete the positioning of the left and right sides of the goods, the insertion rod can be synchronously inserted into the limit plate to limit the gear. When the extrusion block releases the extrusion of the oblique block, the fourth spring is reset, so that the moving plate, the insertion rod, the oblique block and the connecting rod can be reset for the next limiting work.

[0018] 3. The logistics pallet positioning device, through the set rotating mechanism, can realize that when the goods are placed on the pallet body and the goods are transported, under the action of the worm, worm wheel and rotating disk, the L-shaped seat and the universal wheel can be driven to rotate around the fixed disk, that is, the pallet body and the fixed goods can be driven to rotate. The rotating pallet body can make the goods easier to be grabbed by forklifts or other loading and unloading equipment, especially when space is limited or goods need to be transported in different directions, and when the goods stacked on the pallet body need to be checked for damage in a restricted environment, the rotation can make it easier for staff to intuitively inspect the goods, avoiding the complicated process of shuttling back and forth for inspection in a restricted space, improving the efficiency and comprehensiveness of the inspection, and in warehouses and transportation vehicles, the rotating pallet body can help to make more effective use of space, especially when compact stacking or rapid change of direction of goods is required, thereby improving the use effect.

[0019] 4. The logistics pallet positioning device, through the buffer mechanism, can achieve that when the goods are placed on the pallet body for transportation, the placing table and the load-bearing frame will be pressed under the weight pressure of the goods, so that the angle of the connecting axis changes in the load-bearing frame and the moving seat, and the fifth spring is squeezed by sliding on the outer periphery of the slide rod, so that the moving seat can be buffered under the elastic action of the fifth spring. The buffer can buffer the goods when they are placed, avoiding squeezing of the goods at the bottom during the putting down process, thereby protecting the goods. At the same time, during transportation, especially when encountering bumpy roads, the fifth spring can absorb part of the impact force, reduce the damage to the goods caused by vibration or collision, and further ensure the stability of the goods during transportation.

[0034] In actual operation, when this device is used, when it is necessary to place goods through the pallet body 1 and transport the goods, the goods are first stacked on the top of the placement platform 211. Under the weight pressure of the goods, the placement platform 211 can move downward. When the placement platform 211 moves, it will squeeze the load-bearing frame 47, so that the load-bearing frame 47 moves downward, and the connecting shaft 45 changes its angle around the first round rod 44 and the second round rod 46, and drives the moving seat 42 to slide around the sliding rod 41, squeezing the fifth spring 43, so that the moving seat 42 can be buffered under the elastic action of the fifth spring 43. The buffering can play a buffering role on the goods when they are placed, avoiding the goods at the bottom from being damaged during the putting down process. When the placing table 211 moves downward, the rack 213 is driven to move through the connecting block 212, so that the rack 213 drives the gear 218 to rotate, and the rotating block 2191, the supporting column 214, the clamping plate 2197 and the limiting plate 2198 are driven to rotate through the rotating rod 219 under the action of the gear 218, so that the supporting column 214 and the clamping plate 2197 are located on the left and right sides of the goods, and when the clamping plate 2197 contacts with the goods, the first spring 2194 and the second spring 2196 are deformed, and the goods can be fixed under the action of the clamping plate 2197, and the position of the clamping plate 2197 can be automatically adjusted according to the amount of goods. The cargo is fixed in a stable state, and at the same time, according to the height of the cargo stacking, the rectangular frame 2199 is pulled to drive the limit plate 2198 to move, and the telescopic rod 21992 and the third spring 21993 are deformed, so that the inner side of the limit plate 2198 contacts with the top of the cargo, and the top of the cargo can be further positioned by the limit plate 2198. The cargo can be further positioned so that the cargo is in a stable state on the top of the placement table 211. When the placement table 211 moves, the bottom contacts with the top of the pallet body 1 and the top plate 216 respectively, and the support column 214, the clamping plate 2197 and the limit plate 2198 are rotated to complete the positioning of the cargo. When the placement table 211 drives the squeeze plate 2192 to move, the support column 214, the clamping plate 2197 and the limit plate 2198 are rotated to complete the positioning of the cargo. When the pressing block 221 moves to a certain position, the squeezing block 221 squeezes the inclined block 222, so that the squeezing block 221 drives the connecting rod 223, the moving plate 226 and the inserting rod 227 to move, and the fourth spring 225 is deformed. When the support column 214 and the clamping plate 2197 complete the positioning of the left and right sides of the goods, the inserting rod 227 can be synchronously inserted into the limiting plate 2192 to limit the gear 218, so as to avoid the gear 218 rotating due to external factors when the goods are positioned under the action of the support column 214 and the clamping plate 2197, thereby affecting the stability of the support column 214 and the clamping plate 2197. When the goods need to be inspected or other work needs to drive the pallet body 1 and the goods to rotate,First, the second cylinder 32 drives the fixed plate 33 to move, so that the fixed plate 33 drives the rotating plate 34 and the universal wheel 391 to move, and the universal wheel 391 is in contact with the ground. When the contact is completed, the servo motor 37 can be used to drive the worm wheel 36 meshing on the right side of the worm 38 to rotate, so that the worm wheel 36 drives the rotating plate 34 to rotate around the fixed plate 33, and the universal wheel 391 can be driven to rotate. Under the action of the universal wheel 391, the pallet body 1 and the goods can be driven to rotate, and other work such as inspection can be carried out. During the lifting process of the universal wheel 391, it is only necessary to make the universal wheel 391 contact with the ground, so that the bottom of the pallet body 1 is slightly off the ground, to ensure the stability of the pallet body 1 during rotation, and the goods can be inspected. When the transportation is completed and the goods need to be taken down, the first cylinder 215 can be used to drive the top plate 216 to rise and fall, so that the top plate 216 squeezes the placement platform 211, so that the placement platform 211 drives the squeezing block 221 to move, so that the squeezing block 221 releases the squeezing of the inclined block 222. When the squeezing block 221 releases the squeezing of the inclined block 222, the fourth spring 225 is reset, so that the moving plate 226, the insertion rod 227, the inclined block 222 and the connecting rod 223 are reset, and the limit of the limit plate 2192 is released, so that the rack 213 can drive the gear 218 to rotate again, so that the support column 214, the clamping plate 2197 and the limit plate 2198 are away from the left and right sides of the goods, the positioning of the goods is released, and the goods are taken down.
