Description

Technical Field

[0001] This utility model relates to the field of palletizing equipment technology, specifically a lower clamping frame structure for high-efficiency palletizing. Background Technology

[0002] In the rapid development of the modern logistics and warehousing industry, the efficiency of cargo handling and storage has become an important indicator for measuring the operational capabilities of enterprises. As a key process in the cargo storage process, palletizing directly affects the operational efficiency of the entire logistics and warehousing system through its level of automation and operational efficiency. By stacking scattered boxes according to certain rules, palletizing can not only save a significant amount of storage space but also facilitate subsequent transportation and management. The palletizing lower clamp rack, as the core execution component of the palletizing equipment, undertakes the important functions of stable clamping, precise positioning, and reliable handling of goods.

[0003] Existing lower clamping frame structures use a single drive to move one clamping plate while the other is fixed. This leads to uneven force distribution on the box during clamping, making it prone to tilting and falling off, affecting the stability and safety of stacking, and making it difficult to adapt to boxes of different sizes. Furthermore, most clamping plates in existing lower clamping frame structures are fixed, meaning the clamping surface of the plates is not adjustable, resulting in a narrow range of applications. In actual use, it is impossible to flexibly adjust to different box sizes. For example, when clamping and stacking larger boxes, if the contact area of ​​the clamping plates is small, it is difficult to provide sufficient friction, which can cause the boxes to slip or shift during handling.

[0004] Therefore, this utility model provides a lower clamping box frame structure for high-efficiency palletizing to solve the above problems. Utility Model Content

[0019] (III) Beneficial Effects

[0020] 1. By activating the telescopic cylinder, the cylinder will move one of the support plates through the L-shaped connector. When the support plate moves, the rack fixedly connected to it will move one of the clamping plates A and B synchronously. When one rack moves, it will drive the other rack to move in the opposite direction through the gear. Ultimately, the two clamping plates A and B facing each other can clamp the boxes to be stacked. In this way, the two clamping plates A and B clamp the boxes to be stacked in a bidirectional clamping manner, so that the boxes are subjected to uniform force when clamped, avoiding the risk of the boxes tilting or falling off due to uneven force.

[0021] 2. By starting the drive motor, the lead screw A is rotated. When the lead screw A rotates, it drives the fixing part to move along the inner side of the slide groove. At the same time, the fixing part moves and simultaneously drives the clamping plate B. The clamping plate A slides along the inner side of the clamping plate B, thereby adjusting the size of the clamping surface formed by the clamping plate A and the clamping plate B. This can adapt to the clamping of boxes of different sizes and avoid the small contact area between the clamping part and the box to be stacked, which makes it difficult to provide sufficient friction and causes the box to slip or shift during the stacking and handling process.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-7As shown, the purpose of this embodiment is to provide a high-efficiency palletizing lower clamping frame structure, including a support frame 1, an adjusting tube 101 rotatably connected to the inner wall of the support frame 1, a conical transmission wheel A102 fixedly connected to the outer side of the adjusting tube 101, a threaded adjusting rod 103 threadedly connected to the inner wall of the adjusting tube 101, a mounting shell A2 rotatably connected to the bottom end of the threaded adjusting rod 103, a moving block 3 slidably connected to the inner side of the mounting shell A2, and a clamping assembly fixedly connected to the lower surface of the moving block 3;

[0033] The clamping assembly includes a mounting shell B401 fixedly connected to the lower surface of the movable block 3. A movable groove 402 is provided on one side of the mounting shell B401. Limit seats 403 are fixedly connected to both sides inside the mounting shell B401. A rack 404 is slidably connected to the inner side of each of the two limit seats 403. A support column 405 is fixedly connected between the two racks 404 inside the mounting shell B401. A gear 406 is rotatably connected to one end of the support column 405, and the teeth of the gear 406 mesh with the teeth of the two racks 404. A bearing plate 407 is fixedly connected to one end of each of the two racks 404. Both ends of the bearing plate 407 are slidably connected to the inner side of each of the two limit seats 403. A limit groove 408 is provided on the lower surface of each bearing plate 407, and an adjustment component is provided inside each limit groove 408.

[0034] The clamping assembly also includes a fixing seat 409 fixed to the outside of the mounting housing B401. A telescopic cylinder 410 is fixedly connected to the inside of the fixing seat 409. An L-shaped connector 411 is provided at the output end of the telescopic cylinder 410. The outside of the L-shaped connector 411 is slidably adapted to the inside of the movable groove 402. One end of the L-shaped connector 411 is fixedly connected to the outside of one of the bearing plates 407.

[0035] Two memory springs 4081 are symmetrically fixedly connected to the inner side of the limiting groove 408, and one end of each pair of memory springs 4081 is fixedly connected to the outer top of the clamping plate A501.

[0036] In this embodiment, by activating the telescopic cylinder 410, the telescopic cylinder 410 applies force to the L-shaped connector 411, causing the L-shaped connector 411 to move one of the connected bearing plates 407 along the inner side of the limiting seat 403. Simultaneously, the rack 404 fixedly connected to it moves one of the clamping plates A501 and B502 along the inner side of the limiting seat 403. Since the teeth of both racks 404 mesh with the teeth of the gear 406, when one of the... When rack 404 moves, it drives another rack 404 to move relative to it through the transmission of gear 406. Ultimately, both bearing plates 407 drive the connected clamping plates A501 and B502 to move closer or further away in both directions synchronously. This allows the two clamping plates A501 and B502, which are facing each other, to clamp the boxes to be stacked. Through the bidirectional clamping of the two clamping plates A501 and B502, the box is subjected to uniform force when clamped, avoiding the risk of the box tilting or falling off due to uneven force.

[0037] Furthermore, during the clamping process of the two relatively moving clamping plates A501 and B502, both clamping plates A501 and B502 will be subjected to the surface reaction force of the box, thereby causing clamping plate A501 to move inside the limiting groove 408. This causes clamping plate A501 to exert force on the memory spring 4081, causing the memory spring 4081 to undergo elastic deformation. Then, under the buffering effect of the deformation of the memory spring 4081, clamping plates A501 and B502 are not in direct rigid contact with the box, effectively avoiding indentations, deformations, and other issues caused by rigid clamping on the surface of the box.

[0038] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment assembly includes a clamping plate A501. The outer top of the clamping plate A501 is slidably adapted to the inner side of the limiting groove 408. A clamping plate B502 is slidably connected to the inner side of the clamping plate A501. A sliding groove 503 is provided on the outer wall of the clamping plate A501. Supporting plates A504 and B505 are respectively fixedly connected to the two ends of the sliding groove 503 on the outer side of the clamping plate A501. A lead screw A506 is rotatably connected between the outer sides of the support plates A504 and B505. A fixing member 507 is threadedly connected to the outer wall of the lead screw A506. The outer side of the fixing member 507 is slidably adapted to the outer side of the sliding groove 503. One end of the fixing member 507 is fixedly connected to the outer side of the clamping plate B502.

[0039] Mounting brackets A5051 are fixedly connected to the outer side of the support plate B505, and drive motors 5052 are fixedly connected to the inner side of the mounting brackets A5051. The end of the output shaft of the drive motor 5052 passes through the inner wall of the support plate B505 and is fixedly connected to one end of the lead screw A506.

[0040] Both clamping surfaces of clamping plates A501 and B502 are fixedly connected with several anti-slip strips 6.

[0041] In this embodiment, by starting the drive motor 5052, the drive motor 5052 will drive the lead screw A506, which is fixedly connected to it, to rotate synchronously through its output shaft. When the lead screw A506 rotates, it engages with the fixed member 507 through a threaded connection. This rotation of the lead screw A506 then drives the fixed member 507 to move along the inner side of the slide groove 503. Simultaneously, the fixed member 507 moves, synchronously driving the clamping plate B502, which slides along the inner side of the clamping plate A501. The size of the clamping surface formed by clamping plates A501 and B502 is adjusted to accommodate clamping of boxes of different sizes. This avoids situations where the contact area between the clamped component and the box to be stacked is too small, making it difficult to provide sufficient friction and causing the box to slip or shift during stacking and handling. In addition, several anti-slip strips 6 fixed to the clamping surfaces of clamping plates A501 and B502 are used to increase the friction between clamping plates A501 and B502 and the surface of the box, further improving the stability during the clamping process.

[0042] In this embodiment, as Figure 1 and Figure 2 As shown, a mounting bracket B201 is fixedly connected to the outer side of the mounting housing A2, and a drive motor B202 is fixedly connected to the inner side of the mounting bracket B201. One end of the output shaft of the drive motor B202 passes through the interior of the mounting housing A2 and is fixedly connected to a lead screw B203. The outer wall of the lead screw B203 is threadedly connected to the inner wall of the moving block 3, and one end of the lead screw B203 is rotatably connected to the inner side of the mounting housing A2.

[0043] The inner side of the mounting shell A2 is symmetrically fixedly connected with two limiting posts 204, and the outer walls of the two limiting posts 204 are slidably connected to the inner wall of the moving block 3.

[0044] In this embodiment, by starting the drive motor B202, the drive motor B202 will drive the lead screw B203 to rotate synchronously through its output shaft. During the rotation, the lead screw B203, through the threaded engagement with the moving block 3, can drive the moving block 3 to move the clamping assembly and the adjusting assembly horizontally along the inner side of the mounting shell A2, thereby adjusting the horizontal position of the clamping assembly and the adjusting assembly. This ensures that the clamping plates A501 and B502 in the adjusting assembly can be accurately aligned with the boxes to be stacked. Furthermore, while the moving block 3 is moving, the sliding engagement between the two limiting posts 204 symmetrically fixedly connected to the inner side of the mounting shell A2 and the moving block 3 guides and limits the movement trajectory of the moving block 3, ensuring the stability of the moving block 3's horizontal movement along the inner side of the mounting shell A2.

[0045] In this embodiment, as Figure 1 ,and Figure 7 As shown, a mounting base 7 is fixedly connected to the upper surface of the support frame 1, a drive motor A701 is fixedly connected to the inner side of the mounting base 7, a conical transmission wheel B702 is fixedly connected to the end of the output shaft of the drive motor A701, and the outer edge of the conical transmission wheel B702 meshes with the conical transmission wheel A102.

[0046] The inner wall of the support frame 1 is symmetrically slidably connected with two pairs of limiting rods 8, and the bottom ends of the two pairs of limiting rods 8 are fixedly connected to the upper surface of the mounting shell A2.

[0047] In this embodiment, by starting the drive motor A701, the drive motor A701 drives the conical transmission wheel B702 to rotate via its output shaft. When the conical transmission wheel B702 rotates, it meshes with the conical transmission wheel A102, which in turn drives the adjusting tube 101 to rotate. When the adjusting tube 101 rotates, it engages with the threaded adjusting rod 103, which in turn drives the threaded adjusting rod 103 to move the clamping assembly and the adjusting assembly up and down along the axial direction of the adjusting tube 101 via the mounting shell A2. This allows for adjustment of the overall working height of the clamping assembly and the adjusting assembly to accommodate different stacking height requirements. During the lifting and lowering movement of the mounting shell A2, the sliding engagement between the limiting rod 8 fixedly connected to the upper surface of the mounting shell A2 and the support frame 1 restricts the direction of movement of the mounting shell A2, ensuring the stability of the mounting shell A2 when driving the adjusting assembly and the adjusting assembly to move up and down.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
