Description

Technical Field

[0001] This invention relates to the field of logistics racking technology, and in particular to a logistics racking system for easy unloading in warehousing and logistics. Background Technology

[0002] As the logistics industry transforms towards intelligence and efficiency, automated storage and retrieval systems (AS / RS) have become widely used in e-commerce warehousing, automobile manufacturing, food processing, pharmaceutical storage, and other fields due to their core advantages such as high space utilization, small footprint, high degree of automation, high cargo flow efficiency, and low labor costs. However, in the actual operation of AS / RS, there are still significant efficiency bottlenecks and coordination defects in the unloading process, which have become key shortcomings that restrict the improvement of overall warehouse operational efficiency.

[0003] Chinese invention patent CN221564384U discloses an automated warehouse rack for intelligent storage and retrieval of goods, including a rack panel. A drive motor is snapped onto one side of the rack panel. A threaded post is inserted into the drive motor. A movable plate is sleeved on the outer surface of the threaded post. A rocker motor is inserted into the movable plate. A rocker shaft is inserted into the rocker motor. A bushing is sleeved on the outer surface of the rocker shaft. A rocker plate is sleeved on the outer surface of the bushing. A movable motor is inserted into the rocker plate. A movable shaft is inserted into the movable motor. An insert plate is sleeved on the outer surface of the movable shaft. A fixed box is provided on the lower surface of the rack panel. A lifting motor is snapped onto the upper surface of the fixed box.

[0004] The lifting and adjustment of this technology relies on the fixed box under the shelf and the lifting motor. Its lifting stroke and horizontal movement range are limited by its own structural design, and it cannot achieve a large range of horizontal displacement and height adjustment. For the dense rack layout of multi-layer and multi-column in modern automated warehouses, this technology is difficult to cover the storage and retrieval needs of goods in different columns and different heights. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a logistics rack for easy unloading in warehousing and logistics.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a logistics rack for easy unloading in warehousing and logistics, comprising multiple racks arranged in a rectangular array, each rack having a placement cavity, a lifting mechanism being provided on the warehouse floor, a movable rack being slidably disposed in each placement cavity, a lifting frame being provided on the lifting component of the lifting mechanism, the lifting mechanism being used to drive the lifting frame to rise, fall and move, and a moving mechanism being provided on the lifting frame for moving any movable rack out or into the corresponding placement cavity.

[0007] By adopting the above technical solution, the lifting mechanism is first operated to drive the lifting frame to rise and move horizontally until the lifting frame is raised and moved to the placement cavity where the goods to be retrieved are placed. Then, the moving mechanism is operated to move the corresponding moving frame out of the corresponding placement cavity and onto the bottom wall inside the lifting frame. Subsequently, the lifting mechanism is operated to move the lifting frame away from the position of the goods shelf and lower the lifting frame to contact the ground. Then, the moving mechanism is operated to move the moving frame out of the lifting frame. At this point, the goods on the moving frame can be removed, thus completing the operation of removing goods from the goods shelf. By changing the horizontal position and vertical height of the lifting frame, it is possible to store and retrieve goods of various heights and horizontal positions, adapting to the needs of storing and retrieving goods in different columns and at different floor heights, thereby improving the practicality of the device.

[0008] Furthermore, the moving mechanism includes a moving assembly, which includes a moving box slidably disposed on the inner bottom wall of the lifting frame, a driven rod rotatably installed in the moving box, a driven gear fixedly sleeved on the driven rod, a moving gear fixedly sleeved on the driven rod, a moving rack fixedly fixed on the inner bottom wall of the lifting frame, a moving motor fixedly fixed in the moving box, a driving rod fixedly installed on the output end of the moving motor and coaxially disposed with the output end of the moving motor, and a driving gear fixedly sleeved on the driving rod and meshing with the driven gear. The moving rack passes through the moving box and slides in cooperation with the moving box. The moving rack meshes with the moving gear. The moving mechanism also includes a clamping assembly for clamping the moving frame.

[0009] By adopting the above technical solution, when the moving motor is working, it drives the driving rod to rotate, which in turn drives the driving gear fixed to the driving rod, the driven gear meshing with the driving gear, the driven rod fixed to the driven gear, and the moving gear fixed to the driven rod to rotate. Since the moving gear meshes with the moving rack, the moving box can move linearly along the bottom wall of the lifting frame. With the cooperation of the clamping assembly, the moving frame can be clamped and moved, thereby realizing the operation of moving the moving frame out of or into the placement cavity.

[0010] Furthermore, the clamping assembly includes an electric rotary table fixed to the top of the movable box, a horizontal plate fixed to the rotating end of the electric rotary table, and a hydraulic push rod fixed to the horizontal plate. The push rod end of the hydraulic push rod passes through the top of the horizontal plate and slides in cooperation with the horizontal plate. The clamping assembly also includes an insert block fixed to the push rod end of the hydraulic push rod. Each movable frame has a slot on its top for the insert block to pass through and be inserted.

[0011] By adopting the above technical solution, after the movable box moves to a position close to the movable frame, the push rod end of the hydraulic push rod extends, thereby causing the insertion block fixed to the push rod end of the hydraulic push rod to descend until the insertion block is inserted into the slot. At this time, the movable box moves in the opposite direction, and under the limit of the insertion block and slot, the movable frame can be moved out of the placement cavity. In addition, the electric rotary table works and its rotating end drives the horizontal plate to rotate 180 degrees, thereby causing the hydraulic push rod fixed to the horizontal plate and the insertion block fixed to the push rod end of the hydraulic push rod to rotate 180 degrees. With the movement of the movable box, the movable frame on the other side of the shelf can be operated, which facilitates the use of the device.

[0012] Furthermore, the lifting mechanism includes a lifting assembly, which includes two fixed frames fixed to the warehouse floor in a U-shape, a sliding frame slidably mounted on the top of the two fixed frames in a U-shape, a transverse transfer box slidably mounted on the crossbar of the sliding frame, a drive box fixed to the bottom of the transverse transfer box, a take-up and release roller rotatably mounted in the drive box, a lifting rope spirally wound on the take-up and release roller, and a lifting motor fixed to the drive box and driving the take-up and release roller to rotate. The lifting rope passes through the bottom of the drive box and slides in cooperation with the drive box. The lower end of the lifting rope is fixed to the top of the lifting frame. Multiple cargo racks are arranged in the area formed between the two fixed frames. The sliding frame has an automatic movement function. The moving parts of the sliding frame include a limiting pulley rotatably mounted on the sliding frame, a limiting guide rail fixed to the fixed frame and rollingly connected to the limiting pulley, and a drive motor fixed to the sliding frame and driving the limiting pulley to rotate. This part is prior art and will not be described in detail here. The lifting mechanism also includes a transverse transfer assembly for driving the transverse transfer box to move along the crossbar of the sliding frame.

[0013] By adopting the above technical solution, when the lifting motor is working, it drives the take-up and take-up rollers to rotate, which can release or retract the lifting rope, thereby raising and lowering the lifting frame connected to the lifting rope. At the same time, with the cooperation of the sliding frame and the lateral movement component, the horizontal and vertical positions of the lifting frame can be changed to ensure normal cargo storage and retrieval operations.

[0014] Furthermore, the transverse moving assembly includes a transverse moving motor fixed to the transverse moving box, the output end of the transverse moving motor passing through the side wall of the transverse moving box and rotatably connected to the transverse moving box, the transverse moving assembly also includes a transverse moving gear fixedly sleeved on the output end of the transverse moving motor, a transverse moving rack fixed to the cross frame of the sliding frame and meshing with the transverse moving gear, a pulley rotatably mounted on the inner wall of the transverse moving box, and a transverse moving slide rail fixed to the top of the sliding frame and cooperating with the pulley, the transverse moving slide rail passing through the groove on the surface of the pulley and rollingly connected to the surface of the groove.

[0015] By adopting the above technical solution, when the transverse motor is working, it drives the transverse gear to rotate. Since the transverse gear meshes with the transverse rack, the transverse box can move along the crossbar of the sliding frame, thereby changing the horizontal position of the lifting frame between the two fixed frames.

[0016] Furthermore, each of the movable frames is provided with a limiting mechanism, which includes a limiting shell fixed to the bottom wall of the slot and having an annular structure, a sliding block slidably disposed in the limiting shell, an insertion rod that penetrates the inner side wall of the slot and slides with the movable frame, a spring fixed between the sliding block and the bottom wall of the slot, and a connecting column rotatably mounted on the insertion rod. The vertical frame of the goods rack is provided with insertion holes that connect with the insertion rods. The number of insertion holes is equal to the number of insertion rods and their positions correspond one-to-one. The sliding block is provided with an oblique hole that slides with the connecting column.

[0017] By adopting the above technical solution, during the insertion of the insert block into the slot, the bottom of the insert block contacts the top of the sliding block. The sliding block slides down along the limiting shell under force, and the spring is stressed and gradually contracts. Due to the sliding fit between the connecting post and the oblique hole, the connecting post and the insert rod connected to the connecting post can move towards the slot, separating the insert rod from the insertion hole. At this time, pulling the moving frame will move it. Similarly, during the process of the insert block rising and separating from the slot, the spring gradually extends and returns to its original position, thereby driving the sliding block fixed to the spring to rise. With the cooperation of the oblique hole and the connecting post, the insert rod moves away from the slot and re-inserts into the insertion hole, thus realizing the limiting operation of the moving frame and improving the stability of the moving frame placed on the shelf.

[0018] Furthermore, each of the movable frames has an internally hollow structure, and four sliding holes are provided through the top of each movable frame. A crossbar is fixed in each sliding hole, and a clamping block is slidably provided in each sliding hole. The crossbar passes through the corresponding clamping block and slides in cooperation with the corresponding clamping block. Each movable frame is provided with an adjustment mechanism for driving the four corresponding clamping blocks to move closer or further apart.

[0019] By adopting the above technical solution, the goods are first placed between multiple clamping blocks. Then, the adjustment mechanism is operated to drive the four corresponding clamping blocks to move closer to each other until the side walls of the four clamping blocks are in contact with the surface of the goods, thus clamping the goods and improving the stability of the goods when placed on the mobile frame.

[0020] Furthermore, the adjustment mechanism includes an adjustment assembly, which includes a rotating column rotatably mounted on the inner bottom wall of the movable frame and an adjustment disc fixedly sleeved on the rotating column. The adjustment disc has an adjustment hole eccentrically disposed therethrough. The adjustment assembly also includes an adjustment column that slides with the adjustment hole. The adjustment column is connected to a clamping block. The number of adjustment holes, the number of adjustment columns, and the number of clamping blocks are equal and their positions correspond one-to-one. The adjustment mechanism also includes a rotating assembly for driving the rotating column to rotate.

[0021] By adopting the above technical solution, the rotating component drives the rotating column to rotate, which in turn drives the adjusting plate fixed to the rotating column to rotate. Since the adjusting hole and the adjusting plate are eccentrically set, and the adjusting hole and the adjusting column are slidably matched, the adjusting column and the clamping block connected to the adjusting column move towards or away from the axis of the adjusting plate, thereby realizing the operation of clamping or releasing the goods.

[0022] Furthermore, the rotating assembly includes a worm gear fixedly sleeved on the rotating column, a worm rotatably mounted in the movable frame and meshing with the worm gear, and a rotary motor fixed on the movable frame and driving the worm to rotate.

[0023] By adopting the above technical solution, when the rotary motor is working, it drives the worm to rotate, which in turn drives the worm wheel meshing with the worm and the rotating column fixed to the worm wheel to rotate. The locking effect between the worm and the worm wheel ensures the stability of the clamping block after it is properly positioned.

[0024] Furthermore, the clamping block has an anti-slip groove on the side wall near the axis of the adjusting disc, and the adjusting column is rotatably mounted on the bottom of the corresponding clamping block.

[0025] By adopting the above technical solution, the anti-slip groove increases the friction between the clamping block and the goods when they come into contact, and the clamping block is rotatably connected to the adjusting column, which reduces the friction between the adjusting column and the adjusting hole when the adjusting plate rotates.

[0026] In summary, the present invention has the following beneficial effects: In this application, by changing the horizontal position and vertical height of the lifting frame, it is possible to store and retrieve goods of various heights and horizontal positions, adapt to the needs of storing and retrieving goods of different columns and different floor heights, and improve the practicality of the device.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown in the embodiment of this application, a logistics rack for easy unloading in warehousing and logistics is disclosed, including a rack 1, a moving mechanism 5, a lifting mechanism 2, and a limiting mechanism 8. Multiple racks 1 are arranged in a rectangular row. Each rack 1 is provided with a placement cavity, and a moving frame 3 is slidably arranged in each placement cavity. The lifting mechanism 2 is provided with a lifting frame 4 on its lifting component, and the lifting mechanism 2 is used to drive the lifting frame 4 to rise, fall, and move. First, the lifting mechanism 2 is operated to drive the lifting frame 4 to rise, fall, and move horizontally until the lifting frame 4 is raised, lowered, and moved to the placement cavity where the goods need to be retrieved. Then, the moving mechanism 5 is operated to move the corresponding moving frame 3 out of the corresponding placement cavity and onto the bottom wall inside the lifting frame 4. Subsequently, the lifting mechanism 2 is operated to move the lifting frame 4 away from the position of the goods rack 1 and lower the lifting frame 4 to contact the ground. Then, the moving mechanism 5 is operated to move the moving frame 3 out of the lifting frame 4. At this point, the goods on the moving frame 3 can be removed, thus completing the operation of removing the goods from the goods rack 1. This eliminates the tedious operation of manually moving the goods to the corresponding position of the goods rack 1 and manually retrieving them, reducing labor intensity and realizing automatic storage and retrieval operations, thereby improving the automation level of the warehouse. In addition, by changing the horizontal position and vertical height of the lifting frame 4, it is possible to store and retrieve goods of various heights and positions.

[0031] The moving mechanism 5 is mounted on the lifting frame 4 and is used to move any one of the moving frames 3 out of or into the corresponding placement cavity. The moving mechanism 5 includes a moving component 51 and a clamping component 52. The moving component 51 includes a moving box 511, a driven rod 512, a driven gear 513, a moving gear 514, a moving rack 515, a moving motor 516, a driving rod 517, and a driving gear 518. The moving box 511 is slidably mounted on the inner bottom wall of the lifting frame 4, and the driven rod 512 is rotatably mounted inside the moving box 511. The driven gear 513 is fixedly sleeved on the driven rod 512, and the moving gear 514 is fixedly sleeved on the driven rod 512. The moving rack 515 is fixed to the inner bottom wall of the lifting frame 4, and the moving rack 515 passes through the moving box 511 and slides within it. The moving rack 515 meshes with the moving gear 514, and the moving motor 516 is fixed inside the moving box 511. The drive rod 517 is fixedly installed on the output end of the moving motor 516 and is coaxially arranged with the output end of the moving motor 516. The drive gear 518 is fixedly sleeved on the drive rod 517 and meshes with the driven gear 513. When the moving motor 516 is working, it drives the drive rod 517 to rotate, which in turn drives the drive gear 518 fixed to the drive rod 517, the driven gear 513 meshing with the drive gear 518, the driven rod 512 fixed to the driven gear 513, and the moving gear 514 fixed to the driven rod 512 to rotate. Since the moving gear 514 meshes with the moving rack 515, the moving box 511 can move linearly along the inner bottom wall of the lifting frame 4. With the cooperation of the clamping assembly 52, the moving frame 3 can be clamped and moved, thereby realizing the operation of moving the moving frame 3 out of or into the placement cavity.

[0032] The clamping assembly 52 is used to clamp the movable frame 3. The clamping assembly 52 includes an electric rotary table 521, a horizontal plate 522, a hydraulic push rod 523, and an insert block 524. The electric rotary table 521 is fixed to the top of the movable box 511, and the horizontal plate 522 is fixed to the rotating end of the electric rotary table 521. The hydraulic push rod 523 is fixed to the horizontal plate 522, and the push rod end of the hydraulic push rod 523 passes through the top of the horizontal plate 522 and slides in cooperation with the horizontal plate 522. The insert block 524 is fixed to the push rod end of the hydraulic push rod 523, and each movable frame 3 has a slot 6 on its top for the insert block 524 to pass through and be inserted. After the movable box 511 moves to a position close to the movable frame 3, the push rod end of the hydraulic push rod 523 extends, thereby causing the insertion block 524, which is fixed to the push rod end of the hydraulic push rod 523, to descend until the insertion block 524 is inserted into the slot 6. At this time, the movable box 511 moves in the opposite direction, and the insertion block 524 is limited to the slot 6, which can drive the movable frame 3 to move out of the placement cavity. In addition, the electric rotary table 521 works and its rotating end drives the horizontal plate 522 to rotate 180 degrees, thereby driving the hydraulic push rod 523, which is fixed to the horizontal plate 522, and the insertion block 524, which is fixed to the push rod end of the hydraulic push rod 523, to rotate 180 degrees. With the movement of the movable box 511, the movable frame 3 on the other side of the goods shelf 1 can be operated, which facilitates the use of the device.

[0033] The lifting mechanism 2 is mounted on the shelf 1 and is used to drive the lifting frame 4 to rise, fall, and move. The lifting mechanism 2 includes a lifting assembly 21 and a traversing assembly 22. The lifting assembly 21 includes a fixed frame 211, a sliding frame 212, a traversing box 213, a drive box 214, a take-up / release roller 215, a lifting rope 216, and a lifting motor 217. Two fixed frames 211 are provided, fixed to the warehouse floor in a U-shape. The tops of the crossbeams of the two fixed frames 211 are respectively fixed to the tops of the corresponding shelf 1, and multiple shelf 1s are arranged within the area formed between the two fixed frames 211. The sliding frame 212 is slidably mounted on top of two fixed frames 211 in a U-shape. The sliding frame 212 has an automatic movement function. The moving components of the sliding frame 212 include a limiting pulley rotatably mounted on the sliding frame 212, a limiting guide rail fixed to the fixed frame 211 and rollingly connected to the limiting pulley, and a drive motor fixed to the sliding frame 212 and driving the limiting pulley to rotate. This part is prior art and will not be described in detail here. The transverse transfer box 213 is slidably mounted on the crossbar of the sliding frame 212. The drive box 214 is fixed to the bottom of the transverse transfer box 213, and the take-up and release roller 215 is rotatably mounted inside the drive box 214. The lifting rope 216 is spirally wound around the take-up and release roller 215, passing through the bottom of the drive box 214 and slidingly engaging with it. The lower end of the lifting rope 216 is fixed to the top of the lifting frame 4. The lifting motor 217 is fixed to the drive box 214 and drives the take-up and release roller 215 to rotate. When the lifting motor 217 is working, it drives the take-up and take-up rollers 215 to rotate, which can release or retract the lifting rope 216, thereby raising and lowering the lifting frame 4 connected to the lifting rope 216. At the same time, with the cooperation of the sliding frame 212 and the transverse component 22, the horizontal and vertical positions of the lifting frame 4 can be changed to ensure normal cargo storage and retrieval operations.

[0034] The lateral movement assembly 22 is used to drive the lateral movement box 213 to move along the crossbeam of the sliding frame 212. The lateral movement assembly 22 includes a lateral movement motor 221, a lateral movement gear 222, a lateral movement rack 223, a pulley 224, and a lateral movement rail 225. The lateral movement motor 221 is fixed to the lateral movement box 213, and its output end passes through the side wall of the lateral movement box 213 and is rotatably connected to the lateral movement box 213. The lateral movement gear 222 is fixedly sleeved on the output end of the lateral movement motor 221, and the lateral movement rack 223 is fixed to the crossbeam of the sliding frame 212 and meshes with the lateral movement gear 222. The pulley 224 is rotatably mounted on the inner wall of the lateral movement box 213, and the lateral movement rail 225 is fixed to the top of the sliding frame 212 and cooperates with the drive box 214. The lateral movement rail 225 passes through the groove on the surface of the pulley 224 and is in rolling contact with the surface of the groove. When the transverse motor 221 is working, it drives the transverse gear 222 to rotate. Since the transverse gear 222 meshes with the transverse rack 223, the transverse box 213 can move along the crossbar of the sliding frame 212, thereby changing the horizontal position of the lifting frame 4 between the two fixed frames 211.

[0035] A limiting mechanism 8 is installed on the movable frame 3. The number of limiting mechanisms 8 is equal to the number of movable frames 3, and their positions correspond one-to-one. The limiting mechanism 8 includes a limiting shell 81, a sliding block 82, a plug rod 83, a spring 84, and a connecting post 85. The limiting shell 81 is fixed to the inner bottom wall of the slot 6 and has a ring structure. The sliding block 82 is slidably installed inside the limiting shell 81. An oblique hole 9 is provided through the sliding block 82 to slide and engage with the connecting post 85. The plug rod 83 is provided through the inner side wall of the slot 6 and slides and engages with the movable frame 3. An insertion hole 7 is provided through the vertical frame of the shelf 1 to engage with the plug rod 83. The number of insertion holes 7 is equal to the number of plug rods 83, and their positions correspond one-to-one. The spring 84 is fixed between the sliding block 82 and the inner bottom wall of the slot 6. The connecting post 85 is rotatably mounted on the plug rod 83. During the insertion of the insert block 524 into the slot 6, the bottom of the insert block 524 contacts the top of the sliding block 82. The sliding block 82 slides down along the limiting shell 81 under force, and the spring 84 is stressed and gradually contracts. Due to the sliding engagement between the connecting post 85 and the oblique hole 9, the connecting post 85 and the connecting rod 83 connected to the connecting post 85 can move towards the slot 6. The connecting rod 83 separates from the insertion hole 7. At this time, pulling the movable frame 3 will make it move. Similarly, during the process of the insert block 524 rising and separating from the slot 6, the spring 84 gradually extends and returns to its original position, thereby driving the sliding block 82 fixed to the spring 84 to rise. With the cooperation of the oblique hole 9 and the connecting post 85, the connecting rod 83 moves away from the slot 6 and re-engages with the insertion hole 7, thereby realizing the limiting operation of the movable frame 3 and improving the stability of the movable frame 3 placed on the shelf 1.

[0036] Example 2: Figure 3-8 This application discloses a logistics rack for easy unloading in warehousing and logistics, including clamping blocks 12 and an adjusting mechanism 13. Each movable rack 3 has a hollow internal structure. Four sliding holes 10 are provided through the top of each movable rack 3, and a crossbar 11 is fixed in each sliding hole 10. The number of sliding holes 10, the number of clamping blocks 12, and the number of crossbars 11 are equal and their positions correspond one-to-one. The clamping blocks 12 are slidably disposed in the corresponding sliding holes 10, and the crossbars 11 pass through the corresponding clamping blocks 12 and slide in cooperation with them. First, the goods are placed between the clamping blocks 12. Then, the adjusting mechanism 13 is operated to drive the four clamping blocks 12 closer together until the sidewalls of the four clamping blocks 12 are in contact with the surface of the goods, thus clamping the goods and improving the stability of the goods when placed on the movable rack 3.

[0037] The number of adjustment mechanisms 13 is equal to the number of movable frames 3, and their positions correspond one-to-one. Each adjustment mechanism 13 is mounted on a corresponding movable frame 3. The adjustment mechanism 13 is used to drive the four corresponding clamping blocks 12 to move closer or further apart. The adjustment mechanism 13 includes an adjustment component 131 and a rotation component 132. The adjustment component 131 includes a rotating column 1311, an adjustment disk 1312, and an adjustment column 1313. The rotating column 1311 is rotatably mounted on the inner bottom wall of the movable frame 3. The adjustment disk 1312 is fixedly sleeved on the rotating column 1311, and an adjustment hole 14 is provided through the adjustment disk 1312, eccentrically positioned. The adjustment column 1313 slides into the adjustment hole 14 and is connected to the clamping block 12. The number of adjustment holes 14, the number of adjustment columns 1313, and the number of clamping blocks 12 are equal, and their positions correspond one-to-one. The rotating component 132 drives the rotating column 1311 to rotate, which in turn drives the adjusting plate 1312 fixed to the rotating column 1311 to rotate. Since the adjusting hole 14 is eccentrically set with the adjusting plate 1312 and the adjusting hole 14 is slidably engaged with the adjusting column 1313, the adjusting column 1313 and the clamping block 12 connected to the adjusting column 1313 move toward or away from the axis of the adjusting plate 1312, thereby realizing the operation of clamping or releasing the goods.

[0038] The rotating assembly 132 drives the rotating column 1311 to rotate. The rotating assembly 132 includes a worm gear 1321, a worm 1322, and a rotary motor 1323. The worm gear 1321 is fixedly sleeved on the rotating column 1311. The worm 1322 is rotatably mounted in the movable frame 3 and meshes with the worm gear 1321. The rotary motor 1323 is fixed on the movable frame 3 and drives the worm 1322 to rotate. When the rotary motor 1323 is working, it drives the worm 1322 to rotate, which in turn drives the worm gear 1321 meshing with the worm 1322 and the rotating column 1311 fixed to the worm gear 1321 to rotate. The worm 1322 and the worm gear 1321 lock together to ensure the stability of the clamping block 12 after it is adjusted to the correct position.

[0039] An anti-slip groove is provided on the side wall of the clamping block 12 near the axis of the adjusting plate 1312, and the adjusting column 1313 is rotatably mounted on the bottom of the corresponding clamping block 12. The anti-slip groove increases the friction between the clamping block 12 and the goods. The clamping block 12 and the adjusting column 1313 are rotatably connected, which reduces the friction between the adjusting column 1313 and the adjusting hole 14 when the adjusting plate 1312 rotates.
