Description

Technical Field

[0001] This utility model relates to the field of cargo palletizing technology, specifically a palletizing device for import and export of goods. Background Technology

[0002] Palletizing devices for import and export goods are mainly used for the efficient stacking, handling, and loading / unloading of goods in logistics and warehousing. Their core function is to use clamping components to neatly stack boxes, bags, or pallets of different sizes into designated locations according to a preset pattern. They are widely used in ports, factories, and e-commerce warehousing, adapting to the demands of modern logistics for intelligent and flexible operations.

[0003] A palletizing device for import and export of goods, disclosed in Chinese Patent Publication No. CN220466870U, is equipped with a connecting block and a locking block. The locking block is pulled out of the connecting block, and a movable block slides out of a movable slot. Then, the movable block on top of the replacement clamp is aligned with the movable slot and inserted. Releasing the pulling rod allows the locking block to be automatically pushed back into the connecting block by a spring, passing through the locking slot and thus fixing the clamp onto the connecting block. This avoids the cumbersome and complicated operation of disassembling and replacing clamps. However, the overall functionality of the palletizing device is low. When goods are clamped to the appropriate position, it cannot effectively push the goods, which may prevent them from being palletized to the designated position, affecting the overall stability and practicality of the palletizing device. Utility Model Content

[0004] The purpose of this utility model is to provide a palletizing device for importing and exporting goods, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a palletizing device for import and export of goods, including a fixed base, an mounting seat for connecting to an external transport vehicle fixedly connected to the center of the rear end of the fixed base, a clamping mechanism provided in the middle of the interior of the fixed base, clamping arms provided on both sides of the front end of the clamping mechanism, a pushing mechanism provided at the front end of the clamping mechanism, a support plate provided at the bottom end of the fixed base, rollers rotatably connected to the front and rear ends of the upper surface of the support plate, and a limiting mechanism for assembling and disassembling the support plate at the bottom end of the fixed base.

[0006] Preferably, the clamping mechanism includes a servo motor fixedly connected to the center position inside the rear end of the fixed seat. A gear is installed on the output shaft end of the servo motor. The upper and lower ends of the gear are meshed with a rack that slides inside the fixed seat. A connecting block is fixedly connected to the outer side of the front end of the rack. The front end of the connecting block is fixedly connected to the rear end of the clamping arm.

[0007] Preferably, the two racks move in opposite directions, and rubber pads are fixed to the contact surfaces of the two clamping arms with the cargo.

[0008] Preferably, the pushing mechanism includes a connecting shaft fixedly connected to the center position of the front end of the gear, a threaded rod fixedly connected to the front end of the connecting shaft, a threaded cylinder externally threaded to the front end of the threaded rod, a push plate fixedly connected to the front end of the threaded cylinder, and telescopic rods fixedly connected to the upper and lower ends of the rear end of the push plate. The rear end of the telescopic rod is fixedly connected to a fixed seat, and the telescopic rod is used to limit the movement of the threaded cylinder.

[0009] Preferably, the limiting mechanism includes connecting grooves on the left and right sides of the lower surface of the fixed base, movable grooves on the left and right sides inside the fixed base, connecting posts fixedly connected to the left and right sides of the rear end of the upper surface of the pallet, a positioning groove in the middle of the connecting post, a connecting ring rotatably sleeved on the outside of the connecting shaft, through grooves evenly spaced inside the connecting ring, an electromagnet fixedly connected to the rear end of the through groove, a magnetic block slidably connected inside the through groove, a positioning rod fixedly connected to the rear end of the magnetic block, positioning holes evenly spaced at the front end of the gear, pull ropes fixedly connected to the left and right sides outside the connecting ring, a limiting slider that slides in the movable groove fixedly connected to the outside of the pull rope, a spring fixedly connected to the inside of the limiting slider, a positioning block fixedly connected to the outside of the limiting slider, and the outside of the positioning block engaging with the positioning groove.

[0010] Preferably, the number and position of the positioning holes correspond to the positioning rods, and there are four sets in total. The spring on the left is fixed to the lower end of the inner side of the left limiting slider, and the spring on the right is fixed to the upper end of the inner side of the right limiting slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This palletizing device for import and export of goods has a pushing mechanism at the front end of the clamping mechanism. When the servo motor drives the gear to rotate, the gear can push the racks on both sides to move. At this time, the racks can drive the two sets of clamping arms to move relative to each other through the connecting block. At the same time, the gear can drive the threaded rod to rotate in the threaded cylinder through the connecting shaft. When the two sets of clamping arms clamp the goods, the threaded rod can drive the push plate to move backward through the threaded cylinder, so as not to affect the clamping operation of the clamping arms. When the two sets of clamping arms move outward and cancel the clamping of the goods, the threaded rod can push the push plate to move through the threaded cylinder, and the push plate pushes the goods to the designated position, thereby improving the overall functionality and ease of use of the palletizing device.

[0013] 2. This palletizing device for import and export of goods features a pallet at the bottom of a fixed base for assisting in the placement of goods. A connecting post at the top of the pallet inserts into a connecting groove on the fixed base, and a positioning block within the connecting groove engages with the positioning groove on the connecting post, thus installing the pallet at the bottom of the fixed base. When the pallet needs to be removed, energizing an electromagnet within the connecting ring generates a repulsive magnetic force, which moves a magnetic block. This magnetic block then pushes a positioning rod into a positioning hole on a gear. The gear's rotation causes the connecting ring to rotate synchronously, pulling a rope to rewind. This allows the rope to pass through a limit slider, pulling the positioning block out of the positioning groove on the connecting post, enabling quick pallet removal. The operation is simple and convenient, allowing for pallet loading and unloading according to actual usage, thus improving the overall flexibility of the palletizing device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-5 This utility model provides two technical solutions:

[0022] Example 1: A palletizing device for import and export of goods includes a fixed base 1. A mounting base 101 for connecting to an external transport vehicle is fixedly connected to the center of the rear end of the fixed base 1. A clamping mechanism 2 is provided in the middle of the interior of the fixed base 1. Clamping arms 3 are provided on both sides of the front end of the clamping mechanism 2. A pushing mechanism 4 is provided at the front end of the clamping mechanism 2. A pallet 5 is provided at the bottom end of the fixed base 1. Rollers 501 are rotatably connected to the front and rear ends of the upper surface of the pallet 5. The device also includes a limiting mechanism 6, which is used for assembling and disassembling the pallet 5 at the bottom end of the fixed base 1. The palletizing device can be adjusted in height and moved in position by an external transport vehicle. At the same time, the electrical equipment in the palletizing device is started and controlled by an external controller. The rollers 501 at the top of the pallet 5 can reduce the friction generated by the movement of goods at the top of the pallet 5.

[0023] The clamping mechanism 2 includes a servo motor 201 fixedly connected to the center of the rear end of the fixed base 1. A gear 202 is installed on the output shaft end of the servo motor 201. The upper and lower ends of the gear 202 are meshed with a rack 204 that slides inside the fixed base 1. A connecting block 205 is fixedly connected to the outer side of the front end of the rack 204. The front end of the connecting block 205 is fixedly connected to the rear end of the clamping arm 3. When the servo motor 201 is started, it can drive the gear 202 to rotate. At this time, the gear 202 pushes the racks 204 on both sides to move, so that the racks 204 can drive the clamping arm 3 to move through the connecting block 205. Thus, the clamping arm 3 can perform the clamping work of goods that need to be stacked.

[0024] The two racks 204 move in opposite directions, and the two clamping arms 3 are fixed with rubber pads on the contact surfaces with the goods.

[0025] The pushing mechanism 4 includes a connecting shaft 401 fixed at the center of the front end of the gear 202. A threaded rod 402 is fixed at the front end of the connecting shaft 401. A threaded cylinder 403 is externally threaded to the front end of the threaded rod 402. A push plate 404 is fixed at the front end of the threaded cylinder 403. Telescopic rods 102 are fixed at the upper and lower ends of the rear end of the push plate 404. The rear end of the telescopic rod 102 is fixed to the fixed seat 1. The telescopic rod 102 is used to limit the threaded cylinder 403. The gear 202 drives the threaded rod 402 to rotate through the connecting shaft 401. The rotation of the threaded rod 402 inside the threaded cylinder 403 can push the push plate 404 to move telescopically. At the same time, the telescopic rod 102 at the rear end of the push plate 404 can stably limit the threaded cylinder 403 and prevent the threaded cylinder 403 from rotating with the threaded rod 402.

[0026] Example 2 differs from Example 1 mainly in that:

[0027] A palletizing device for importing and exporting goods includes a fixed base 1.

A clamping mechanism 2 is provided in the middle of the interior of the fixed base 1. Clamping arms 3 are provided on both sides of the front end of the clamping mechanism 2. A pushing mechanism 4 is provided at the front end of the clamping mechanism 2. A support plate 5 is provided at the bottom end of the fixed base 1. Rollers 501 are rotatably connected to the front and rear ends of the upper surface of the support plate 5. The device also includes a limiting mechanism 6, which is used for assembling and disassembling the support plate 5 at the bottom end of the fixed base 1.

[0028] The clamping mechanism 2 includes a servo motor 201 fixedly connected to the center of the rear end of the fixed base 1. A gear 202 is installed on the output shaft end of the servo motor 201. The upper and lower ends of the gear 202 are meshed with a rack 204 that slides inside the fixed base 1. A connecting block 205 is fixedly connected to the outer side of the front end of the rack 204. The front end of the connecting block 205 is fixedly connected to the rear end of the clamping arm 3.

[0029] The two racks 204 move in opposite directions, and the two clamping arms 3 are fixed with rubber pads on the contact surfaces with the goods.

[0030] The pushing mechanism 4 includes a connecting shaft 401 fixedly connected to the center of the front end of the gear 202. A threaded rod 402 is fixedly connected to the front end of the connecting shaft 401. A threaded cylinder 403 is externally threaded to the front end of the threaded rod 402. A push plate 404 is fixedly connected to the front end of the threaded cylinder 403. Telescopic rods 102 are fixedly connected to the upper and lower ends of the rear end of the push plate 404. The rear end of the telescopic rod 102 is fixedly connected to the fixed seat 1. The telescopic rod 102 is used to limit the movement of the threaded cylinder 403.

[0031] The limiting mechanism 6 includes connecting grooves 103 on the left and right sides of the lower surface of the fixed base 1, movable grooves 104 on the left and right sides inside the fixed base 1, connecting posts 502 fixedly connected to the left and right sides of the rear end of the upper surface of the support plate 5, positioning grooves 503 in the middle of the connecting posts 502, connecting rings 601 rotatably sleeved on the outside of the connecting shaft 401, through grooves 602 evenly spaced and equidistantly centered inside the connecting rings 601, and electromagnets 603 fixedly connected to the rear end of the through grooves 602. A magnetic block 604 is internally slidably connected to the gear 202. A positioning rod 605 is fixedly connected to the rear end of the magnetic block 604. Positioning holes 203 are evenly spaced at the front end of the gear 202. Pull ropes 606 are fixedly connected to the left and right sides of the outer side of the connecting ring 601. A limiting slider 607 that slides in the movable groove 104 is fixedly connected to the outer side of the pull rope 606. A spring 608 is fixedly connected to the inner side of the limiting slider 607. A positioning block 609 is fixedly connected to the outer side of the limiting slider 607. The outer side of the positioning block 609 is inserted into the positioning groove 503. When the electromagnet 603 is energized... A repulsive force can be generated, at which point the electromagnet 603 can push the magnetic block 604 to move, and the magnetic block 604 pushes the positioning rod 605 to insert into the positioning hole 203 on the gear 202. At this time, the connecting ring 601 can rotate with the gear 202. When the connecting ring 601 rotates, it can pull the pull ropes 606 on both sides to rewind. At this time, the pull ropes 606 can squeeze the spring 608 through the limit slider 607, and the limit slider 607 will drive the positioning block 609 to enter the movable groove 104. When the current flow in the electromagnet 603 is changed, an attractive force is generated, which causes the magnetic block 604 to drive the positioning rod 605 to be pulled out from the positioning hole 203 on the gear 202. At this time, the reaction force of the spring 608 being squeezed can push the positioning block 609 to reset through the limit slider 607. When the connecting post 502 on the support plate 5 is inserted into the connecting groove 103 on the fixed base 1, the positioning block 609 is inserted into the positioning groove 503 on the connecting post 502, and the position of the support plate 5 at the bottom of the fixed base 1 is fixed.

[0032] The number and position of the positioning holes 203 correspond to the positioning rods 605, and there are four sets of each. The left spring 608 is fixed to the lower end of the inner side of the left limiting slider 607, and the right spring 608 is fixed to the upper end of the inner side of the right limiting slider 607. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] In this embodiment, the goods to be stacked are pushed to the top of the pallet 5. At this time, the servo motor 201 in the fixed base 1 is started, which drives the gear 202 to rotate. The gear 202 drives the racks 204 on both sides to rotate, and the racks 204 can drive the connecting block 205 to move. The connecting block 205 drives the clamping arm 3 to complete the clamping work of the goods. At this time, the transport vehicle can drive the stacking device to a suitable position and height. The servo motor 201 drives the gear 202 to rotate in the opposite direction, and the gear 202 can drive the racks 204 on both sides to move. The racks 204 drive the clamping arm 3 through the connecting block 205 to release the clamping of the goods. At the same time, the gear 202 drives the threaded rod 402 to rotate. The threaded rod 402 rotates in the threaded cylinder 403 and can push the push plate 404 to push the goods out from the top of the pallet 5, thereby quickly performing the goods stacking work.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
