Description

A transmission structure for a tray threading device Technical Field

[0001] This utility model relates to the field of pallet strapping devices, specifically a transmission structure for a pallet strapping device. Background Technology

[0002] The core function of the strapping device is to achieve fully automatic strapping, replacing the traditional manual operation of strapping palletized goods by bending over. It works in concert with a drive motor, chain drive and intelligent control unit to ensure that the strapping passes through the gaps of the goods or pallet quickly and accurately and completes the binding, thus improving strapping efficiency. However, the guide chain drive of the existing strapping device has poor stability, and the structure of stopping the chain from sliding when it stops is complicated. Summary of the Invention

[0003] Therefore, the purpose of this utility model is to provide a transmission structure for a pallet threading device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transmission structure for a pallet strapping device, comprising a front side plate and a rear side plate, the front side plate and the rear side plate forming a housing, two sets of drive components installed on one side of the front side plate, and a drive shaft provided at the output end of the drive components, a sprocket sleeved on the outer wall of the drive shaft, and a sliding groove provided on the inner wall of both the front side plate and the rear side plate, and an upper guide chain and a lower guide chain provided on the inner wall of the sliding groove, the upper guide chain being composed of multiple sets of connecting members, each set of connecting members being movably connected and capable of limiting the rotation angle between the connecting members, when the upper guide chain and the lower guide chain extend to the ground, the upper guide chain and the lower guide chain are superimposed and attached to each other on the same horizontal plane.

[0005] By adopting the above technical solution, the stability of the threading device is improved by using two sets of sprocket drives. The motor can be programmed to execute commands through the control unit, and the extension length of the upper or lower guide chain can be dynamically adjusted to adapt to the threading requirements of pallets of different specifications. Furthermore, the chain can be braked by stopping the power output of the motor, and precise extension and synchronous retraction are achieved. The upper guide chain is composed of multiple connecting parts with an I-shaped design. Through the cooperation of the limiting block and the limiting groove, a small range of limiting rotation between the two connecting parts can be achieved, so that the upper guide chain can maintain a smooth forward extension movement. Moreover, when the upper guide chain is off the ground, the limiting rotation between the chain links can keep the upper guide chain extending upward.

[0006] The present invention is further configured such that an inner groove and an outer groove are respectively provided at both ends of the connector, and a limiting groove is provided on the inner wall of both the inner groove and the outer groove, and a limiting block is fixed inside the inner groove and the outer groove. A convex shaft is fixed on the inner wall of the outer groove, and a through hole is provided on the inner wall of the inner groove.

[0007] Preferably, each set of connectors is rotatably connected by a convex shaft. In use, each set of connectors rotates around the convex shaft. When the connectors rotate, the limiting block moves on the inner wall of the limiting groove. The limiting block and the limiting groove cooperate to limit the rotation angle of each set of connectors.

[0008] The present invention is further configured such that bearings are provided on both sides of the sprocket, and the bearings are installed inside the front side plate and the rear side plate.

[0009] Preferably, by incorporating bearings, the friction between the sprocket and the front and rear side plates can be reduced.

[0010] The present invention is further provided that mounting holes are provided inside both the front side plate and the rear side plate.

[0011] Preferably, the mounting holes facilitate the installation of bearings.

[0012] The present invention is further configured such that a connecting block is installed on one side of the rear side plate, and the connecting block is located on one side of the sprocket.

[0013] Preferably, the connecting block can limit the sprocket and prevent it from wobbling.

[0014] In summary, the present invention has the following main advantages:

[0015] This utility model features an upper guide chain, a lower guide chain, sprockets, connectors, limiting blocks, and limiting grooves. Two sets of sprockets enhance the stability of the threading device. The motor can be programmed via a control unit to dynamically adjust the extension length of either the upper or lower guide chain, adapting to the threading requirements of different pallet sizes. The chain is braked by stopping the motor's power output, ensuring precise extension and synchronous retraction. The upper guide chain consists of multiple connectors arranged in an I-shape. The limiting blocks and limiting grooves work together to allow for small-range limiting rotation between connector sections, ensuring smooth forward extension of the upper guide chain. Furthermore, when the upper guide chain is off the ground, the limiting rotation between the chain links allows it to extend upwards. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please refer to Figures 1-5. The device includes a front side plate 1 and a rear side plate 2, which together form a housing. Two sets of drive components are installed on one side of the front side plate 1. The drive components are motors 6, and the output end of the drive components is provided with a transmission shaft 61. A sprocket 10 is sleeved on the outer wall of the transmission shaft 61. The inner walls of both the front side plate 1 and the rear side plate 2 are provided with sliding grooves 5. The inner walls of the sliding grooves 5 are provided with an upper guide chain 3 and a lower guide chain 4. The upper guide chain 3 is composed of multiple sets of connecting parts 9. Each set of connecting parts 9 is movably connected and can limit the rotation angle between the connecting parts 9. When the upper guide chain 3 and the lower guide chain 4 extend to the ground, they overlap and fit together on the same horizontal plane.

[0026] In the above embodiment, please refer to Figures 4 and 5 for details. The two ends of the connector 9 are respectively provided with an inner groove 91 and an outer groove 92. The inner walls of the inner groove 91 and the outer groove 92 are provided with a limiting groove 94. The inner groove 91 and the outer groove 92 are fixed with a limiting block 93. The inner wall of the outer groove 92 is fixed with a convex shaft 95. The connector 9 is I-shaped. The inner wall of the inner groove 91 is provided with a through hole 96. Each set of connectors 9 is rotatably connected by the convex shaft 95. In use, each set of connectors 9 rotates around the convex shaft 95. When the connector 9 rotates, the limiting block 93 moves in the inner wall of the limiting groove 94. The limiting block 93 cooperates with the limiting groove 94, thereby limiting the rotation angle of each set of connectors 9.

[0027] In the above embodiment, please refer to Figure 3 for details. Bearings 8 are provided on both sides of the sprocket 10, and the bearings 8 are installed inside the front side plate 1 and the rear side plate 2. By providing bearings 8, the friction between the sprocket 10 and the front side plate 1 and the rear side plate 2 can be reduced.

[0028] In the above embodiment, please refer to Figure 3 for details. The front side plate 1 and the rear side plate 2 are both provided with mounting holes 7, which can facilitate the installation of bearings 8.

[0029] In the above embodiment, please refer to the figure for details. A connecting block 11 is installed on one side of the rear plate 2, and the connecting block 11 is located on one side of the sprocket 10. The setting of the connecting block 11 can limit the sprocket 10 and prevent the sprocket 10 from shaking.

[0030] In practical operation, the present invention is as follows: the motor 6 drives the transmission shaft 61 to work, and the transmission shaft 61 drives the sprocket 10 to rotate. When the sprocket 10 rotates, it drives the upper guide chain 3 and the lower guide chain 4 to slide out from the inside of the slide groove 5. The lower guide chain 4 contacts the ground, and the upper guide chain 3 slides above the lower guide chain 4. When the upper guide chain 3 and the lower guide chain 4 are separated from the inner wall of the slide groove 5, they are on the same horizontal plane. When the upper guide chain 3 is deflected by the guiding component, each set of connecting parts 9 rotates through the convex shaft 95. With the cooperation of the limiting block 93 and the limiting groove 94, the rotation angle between each set of connecting parts 9 is limited, so that the upper guide chain 3 maintains a smooth forward extension movement.
