In the logistics industry, the bundling of logistics bags is a key link to ensure the stability of cargo transportation and prevent cargo from scattering.

[0003] However, existing logistics bag strapping devices have many shortcomings in practical applications: the logistics bags are prone to positional shifts during the strapping process, resulting in inaccurate strapping positions. This makes the strapped logistics bags very prone to loosening during transportation, seriously affecting the safety of cargo transportation.

[0004] Therefore, a logistics bag bundling device with an anti-loosening structure is proposed to address the above problems. Utility Model Content

It has the advantages of precise positioning and flexible buffering through mechanical clamping components, and flexible adaptation and flexible protection through pressing components, thereby comprehensively ensuring that the logistics bag is not loosened and is protected from damage after bundling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a logistics bag bundling device with an anti-loosening structure, comprising a machine body, a worktable fixedly connected to the top of the machine body, a bundling mechanism provided on the worktable, mechanical clamping components provided on both the front and rear sides of the bundling mechanism, the mechanical clamping components being mounted on the worktable, and a pressing component connected to the top of the bundling mechanism.

One end of the bidirectional lead screw is connected to the worktable via a bearing, and the other end passes through the worktable and is connected to a drive motor. A displacement block is connected between the bidirectional lead screw and the guide slide rod. The two displacement blocks are symmetrically arranged and move in opposite directions. A connecting plate is fixedly connected to the top of the displacement block, and the connecting plate passes through the worktable and is fixedly connected to a moving plate.

[0009] Preferably, the displacement block is provided with a threaded hole and a guide sliding hole, the threaded hole is threaded to a two-way lead screw, and the inner wall of the guide sliding hole slides against the guide slide rod.

[0010] Preferably, a strip-shaped through groove is provided on the worktable at the position corresponding to the connecting plate, and the connecting plate passes through the strip-shaped through groove.

It uses components such as bidirectional lead screw and guide slide to ensure that the logistics bags do not shift during the binding process, providing a basic guarantee for preventing loosening. At the same time, it uses the buffer spring of the spring buffer rod, the movable plate and the movable rod to form a flexible buffer during clamping, avoiding the pressure damage to the logistics bags caused by rigid clamping, and making the clamping more close and stable, reducing the possibility of loosening after binding from the source. 2. The clamping assembly of this utility model, on the one hand, facilitates quick disassembly and position adjustment through the cooperation of the positioning groove, positioning block and fixing bolt at the bottom of the horizontal plate, and can flexibly adapt to the bundling needs of logistics bags of different sizes, thus improving the versatility of the device.

In conjunction with the mechanical clamping assembly, it comprehensively ensures the anti-loosening performance of the bundled logistics bag. Attached Figure Description

[0017] 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.

[0018] like Figures 1 to 6 As shown, this utility model provides a logistics bag bundling device with an anti-loosening structure, including a body 1, a workbench 2 fixedly connected to the top of the body 1, the workbench 2 providing a stable operating platform for the whole device, a bundling mechanism 3 for performing logistics bag bundling operations is provided on the workbench 2, mechanical clamping components 4 are provided on both the front and rear sides of the bundling mechanism 3 to accurately clamp and position the logistics bag and prevent it from shifting during bundling, the mechanical clamping components 4 are installed on the workbench 2, and a pressing component 5 is connected to the top of the bundling mechanism 3 to press the logistics bag from the top and further prevent it from loosening after bundling.

[0019] Specifically, the mechanical clamping assembly 4 includes a reciprocating shifting structure 41 on the worktable 2. The reciprocating shifting structure 41 is connected to two moving plates 42 that can be driven by it to move precisely and stably relative to each other to adapt to logistics bags of different widths. Multiple spring buffer rods 43 are installed on the moving plates 42 to provide cushioning during clamping, avoid rigid pressure damage to the logistics bags, and make the clamping more close and stable to improve the anti-loosening effect. The ends of the spring buffer rods 43 are connected to clamping plates 44.

[0020] Furthermore, the reciprocating displacement structure 41 includes a bidirectional lead screw 411 and a guide slide 412. The outer wall of the bidirectional lead screw 411 is provided with symmetrical threads in opposite directions. One end of the bidirectional lead screw 411 is connected to the worktable 2 via a bearing, and the other end passes through the worktable 2 and is connected to a drive motor 413. The drive motor 413 can drive the bidirectional lead screw 411 to rotate. A displacement block 414 is connected between the bidirectional lead screw 411 and the guide slide 412. The two displacement blocks 414 are symmetrically arranged and move in opposite directions. A connecting plate 415 is fixedly connected to the top of the displacement block 414. The connecting plate 415 passes through the worktable 2 and is fixedly connected to the moving plate 42. By rotating the bidirectional lead screw 411 and coordinating with the guide slide 412, the two displacement blocks 414 can drive the moving plate 42 to move closer or further away from each other precisely to accommodate the clamping of logistics bags of different sizes.

[0021] Furthermore, the displacement block 414 is provided with a threaded hole 416 and a guide slide hole 417. The threaded hole 416 is threadedly connected to a two-way lead screw 411, and the threaded engagement ensures the movement accuracy of the displacement block 414. The inner wall of the guide slide hole 417 slides against the guide slide rod 412, and the sliding engagement provides stable guidance for the displacement block 414 and prevents rotational deviation.

[0022] It is worth noting that a strip-shaped through groove 418 is provided on the workbench 2 at the position corresponding to the connecting plate 415. The connecting plate 415 passes through the strip-shaped through groove 418, which provides space for the moving plate 415 to move, ensuring that the moving plate 42 moves smoothly with the displacement block 414.

[0023] It is worth noting that the spring buffer rod 43 includes a cylinder 431 fixed on the movable plate 42. A movable plate 432 is provided inside the cylinder 431. A buffer spring 433 is connected to the side of the movable plate 432 away from the clamping plate 44. A movable rod 434 is fixedly connected to the side of the movable plate 432 away from the buffer spring 433. The end of the movable rod 434 passes through the cylinder 431 and is fixedly connected to the clamping plate 44. When the clamping plate 44 contacts the logistics bag, the movable rod 434 drives the movable plate 432 to compress the buffer spring 433, using elasticity to achieve flexible buffering. A protective pad 45 is provided on the opposite side of the clamping plate 44. The protective pad 45 increases the friction with the logistics bag, improves the clamping stability, and avoids damage to the surface of the logistics bag.

[0024] It is worth mentioning that the pressing assembly 5 includes a horizontal plate 51 located at the top of the strapping mechanism 3. Two cylinders 52 are installed on the horizontal plate 51, which are symmetrically arranged front and back. The piston rod of the cylinder 52 is connected to the pressing plate 53. The cylinder 52 can drive the pressing plate 53 to move up and down to press the top of the logistics bag. The pressing plate 53 and the clamping plate 44 are staggered front and back. This layout allows the pressing and clamping to act on different areas of the logistics bag, preventing loosening after strapping in all directions.

[0025] It is worth emphasizing that a positioning groove 54 is provided at the bottom of the horizontal plate 51, and a positioning block 55 is provided in the positioning groove 54. The bottom of the positioning block 55 is fixedly connected to the frame of the strapping mechanism 3. The positioning block 55 and the horizontal plate 51 are connected by a fixing bolt 56. The horizontal plate 51 is easy to disassemble and assemble by the cooperation between the positioning groove 54 and the positioning block 55 and the fixing bolt 56. A sponge pad 57 is provided at the bottom of the pressing plate 53. The sponge pad 57 is flexible and avoids damaging the logistics bag when pressing. At the same time, it enhances the contact and fit with the logistics bag and improves the anti-loosening effect of the top pressing.

[0026] The binding mechanism 3, drive motor 413, and cylinder 52 are existing technologies and will not be described in detail. In addition, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail.

[0027] Working principle and process: First, place the logistics bag to be bundled on the worktable 2 at the top of the machine body 1, aligning the logistics bag with the working area of ​​the bundling mechanism 3. Then, start the mechanical clamping assembly 4, drive the motor 413 to rotate, and rotate the bidirectional lead screw 411. Because the outer wall of the bidirectional lead screw 411 has symmetrical threads with opposite directions, in conjunction with the guide slide rod 412 guiding the displacement blocks 414, the two displacement blocks 414 move closer to each other along the bidirectional lead screw 411 and the guide slide rod 412. The displacement blocks 414 drive the moving plate 42 to move closer to the logistics bag synchronously through the connecting plate 415 at the top, until the clamping plate 44 at the end of the spring buffer rod 43 on the moving plate 42 contacts the logistics bag. At this time, the moving rod 434 is squeezed and pushes the moving plate 432 to compress the buffer spring 43 inside the cylinder 431. 3. The elasticity of the buffer spring 433 is used to achieve flexible clamping of the logistics bag. The protective pad 45 on the opposite side of the clamping plate 44 further protects the surface of the logistics bag and improves the clamping stability. Then, the pressing assembly 5 is activated, and the two cylinders 52 on the horizontal plate 51 drive the piston rod to extend, which drives the pressing plate 53 with the sponge pad 57 at the bottom to move downward, and flexibly presses the top of the logistics bag. After the logistics bag is positioned and pressed, the strapping mechanism 3 is activated and performs the strapping operation on the logistics bag. After the strapping is completed, the cylinder 52 drives the pressing plate 53 to reset, and the drive motor 413 reverses to make the bidirectional lead screw 411 rotate in the opposite direction. The displacement block 414 drives the moving plate 42, the spring buffer rod 43 and the clamping plate 44 away from the logistics bag. Finally, the strapped logistics bag is removed, completing a complete anti-loosening strapping process.
