Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a binding table for sofa manufacturing. Background Technology

[0002] Sofas, as an important category of upholstered furniture, are multi-seat chairs equipped with cushions. Their backrests typically use a spring structure or thick foam padding, and they have armrests on both sides, combining functionality and comfort. In a home environment, the comfort of the living room is closely related to the matching of home decorations, and an ergonomically designed sofa is a core component of the living room space, significantly enhancing the quality of life. Therefore, as a mass-market consumer product, sofas are characterized by their wide range of uses and high market demand, making them an indispensable basic furniture item in modern home decoration.

[0003] The prior art utility model with authorization announcement number CN217099104U is entitled: A binding table for wooden packaging boxes, which includes a support frame, a rotating table, a sliding groove, a first pushing structure, a second pushing structure and a rotating structure. The support frame is a circular structure. The rotating table is rotatably connected inside the support frame. The rotating structure is provided at the bottom of the support frame. The sliding groove is provided on the rotating table. A fixing block is fixedly connected to the inner side wall of the sliding groove. This application extends an electric push rod to clamp the aligned horizontal and vertical plates together with locking pads one and two. The electric push rod then retracts, moving the horizontal and vertical plates to align the other side of each plate. This allows for binding, facilitating independent binding by workers and effectively saving labor. The application also utilizes a rotating motor to move the horizontal and vertical plates, bringing the binding points closer to the workers, simplifying the binding process and preventing workers from running around. However, this invention relies on multiple electric push rods and motors working together. While this achieves convenient binding, it significantly increases initial procurement costs. Furthermore, as high-precision electromechanical components, the electric push rods and motors require regular lubrication, component inspection, and circuit testing during long-term operation. This not only consumes manpower but also incurs additional expenses for parts replacement and labor services, significantly increasing the overall lifecycle cost of the equipment.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-4As shown, a binding table for sofa manufacturing includes: a workbench 1, an mounting box 2 fixedly installed on the front end of the outer surface of the workbench 1, a motor 7 fixedly installed inside the mounting box 2, a threaded rod 8 fixedly installed on the output end of the motor 7, a sliding block 16 threadedly installed on one end of the shaft surface of the threaded rod 8 through the outer surface of the workbench 1, a second connecting plate 15 fixedly installed on both sides of the bottom end of the outer surface of the sliding block 16, a first connecting plate 13 provided at the bottom of the outer surface of the second connecting plate 15 away from the sliding block 16, and a positioning shaft 14 penetrating the outer surface at the intersection of the outer surfaces of the second connecting plate 15 and the first connecting plate 13. The first connecting plate 13 has a positioning rod 12 inserted into the end of its outer surface away from the positioning shaft 14. A slider 24 is fixedly installed at the bottom of the outer surface of the positioning rod 12. A slide rail 9 is slidably installed on the outer surface of the slider 24, and the bottom of the outer surface of the slide rail 9 is installed at the bottom of the inner side of the worktable 1. A mounting plate 10 is installed at the top of the middle of the outer surface of the slider 24. A return spring 11 is fixedly installed at the end of the outer surface of the mounting plate 10 away from the positioning rod 12, and one end of the outer surface of the return spring 11 is fixedly installed on one side of the worktable 1. A connecting rod 3 is fixedly installed on the side of the outer surface of the slider 24 close to the worktable 1.

[0022] In the above scheme, the core of the binding table is the workbench 1. A mounting box 2 is fixedly installed at the front end of the workbench 1, containing the drive core—motor 7. The output shaft of motor 7 directly drives the threaded rod 8 to rotate. One end of the threaded rod 8 passes through a specific position on the workbench 1 and is connected to a moving block 16 via a threaded engagement. This means that when motor 7 rotates forward and reverse, the threaded rod 8 drives the moving block 16 to move linearly along the axis of the threaded rod 8 (usually parallel to the length of the workbench 1). Two second connecting plates 15 are fixedly connected to the bottom sides of the moving block 16. A first connecting plate 13 is connected to the bottom of the lower end of each second connecting plate 15 (the end furthest from the moving block 16). These two connecting plates are hinged together at their intersection by a positioning shaft 14, forming a structure similar to a "toggle" or "linkage". The end of the first connecting plate 13 furthest from the positioning shaft 14 is inserted into (or hinged to) a positioning rod 12. The bottom ends of the two positioning rods 12 are fixedly mounted on a slider 24, which is mounted on a slide rail 9. The slide rail 9 is fixedly mounted on the inner bottom surface of the worktable 1. This means that the slider 24 can only slide along the path defined by the slide rail 9. A mounting plate 10 is mounted above the middle of the slider 24. One end of the mounting plate 10 (away from the positioning rods 12) is connected to a return spring 11, and the other end of the return spring 11 is fixed to one side of the worktable 1. The function of the return spring 11 is to provide a pulling or pushing force, so that the slider 24 tends to return to its initial position when no other force is applied. In addition, a connecting rod 3 is also fixedly connected to the side of the slider 24 near the worktable 1.

[0023] Reference Figure 1-4As shown, a positioning block 4 is installed at the top and bottom of the outer surface of the linkage rod 3. A mounting box 5 is fixedly installed at the front end of the outer surface of the positioning block 4. The outer surfaces of the positioning block 4 and the mounting box 5 are connected by bolts 6. Telescopic rods 17 are fixedly installed on the left and right sides inside the mounting box 5. A compression spring 18 is provided on the outer side of the shaft surface of the telescopic rod 17. A clamping plate 19 is fixedly installed on the front end of the outer surface of the compression spring 18 and the telescopic rod 17. The outer surface of the clamping plate 19 is snapped into the interior of the mounting box 5. A shaft 20 is fixedly installed on the inner side of the front end of the outer surface of the clamping plate 19. A clamping block 21 is inserted into the shaft surface of the shaft 20. Snap-fit ​​grooves are opened on both sides of the outer surfaces of the clamping block 21 and the shaft 20. Snap-fitting member 22 is snapped into the snap-fit ​​grooves of the shaft 20 and the clamping block 21. A handle 23 is fixedly installed on one side of the outer surface of the snap-fitting member 22.

[0024] In the above scheme, a positioning block 4 is connected to the lower top of the linkage rod 3, and a mounting box 5 is fixedly installed at the front end of the positioning block 4. The positioning block 4 and the mounting box 5 are fixedly connected by bolts 6. Telescopic rods 17 are fixedly installed on the left and right sides inside the mounting box 5. A compression spring 18 is fitted on the outside of the bushing of each telescopic rod 17. The compression spring 18 and the front end of the telescopic rod 17 are fixedly connected to a clamping plate 19. The clamping plate 19 itself is snapped into the inside of the mounting box 5 to ensure its stable movement trajectory. A plug shaft 20 is fixedly installed on the inner side of the front end of each of the two clamping plates 19. A clamping block 21 is inserted into each plug shaft 20. In order to ensure that the clamping block 21 is firmly installed on the plug shaft 20, corresponding buckle grooves are opened on the sides of both. A buckle 22 is embedded in these buckle grooves to lock the clamping block 21 on the plug shaft 20. To facilitate the operation of the buckle 22, a handle 23 is fixedly installed on one side.

[0025] Working principle and implementation: Starting motor 7 drives threaded rod 8 to rotate. Threaded rod 8 drives moving block 16 linearly, which in turn pushes second connecting plate 15. Second connecting plate 15 drives first connecting plate 13 via positioning shaft 14. First connecting plate 13 pushes positioning rod 12, thereby driving slider 24 to overcome the force of return spring 11 and move along slide rail 9. The movement of slider 24 is transmitted through linkage rod 3, driving the entire mounting box 5 and clamping mechanism to move. When clamping block 21 contacts the sofa component placed at the binding position, clamping plate 19 retracts into mounting box 5 under pressure, compressing compression spring 18. The elastic force generated by compression spring 18 acts on the workpiece through clamping plate 19 and clamping block 21, providing stable clamping force. Telescopic rod 17 mainly serves as a guide, ensuring smooth linear movement of clamping plate 19. When motor 7 reverses, moving block 16 moves in the opposite direction. With the assistance of the return spring 11, the slider 24 is pulled back to its original position, the linkage rod 3 drives the clamping mechanism to leave the workpiece, and the compression spring 18 also helps the clamping plate 19 to reset. By operating the handle 23 to release the buckle 22, the clamping block 21 can be removed from the insert shaft 20 for replacement to adapt to sofa parts of different shapes or sizes.
