Description

Technical Field

[0001] This utility model relates to the field of edge banding processing technology, and in particular to a fixed-length cutting processing equipment for multi-specification seat edge banding. Background Technology

[0002] In the automotive seat manufacturing industry, piping strips are widely used as an important covering material for the decoration and reinforcement of seat edges. In order to meet the requirements of different seat models and designs, piping strips of various specifications need to be processed. Fixed-length cutting is a key step in piping strip processing, and its quality directly affects the subsequent sewing efficiency and the aesthetics and durability of the finished seat. Therefore, developing a high-efficiency, precise piping strip fixed-length cutting processing equipment that can adapt to multiple specifications is of great practical significance.

[0003] Currently, in the fixed-length cutting of hem strips, common equipment typically employs a linear cutting method. This type of equipment generally includes a machine base, a conveyor belt, a positioning device, and a linearly moving cutting tool. During operation, the hem strip material is conveyed to the set length by the conveyor belt, fixed by the positioning device, and then the cutting tool moves vertically or obliquely downward along a linear trajectory to complete the cutting of the hem strip. Its technical principle mainly relies on a precise length measurement and control system and a stable linear feed drive mechanism for the cutting tool to achieve fixed-length cutting.

[0004] However, the straight-line cutting method commonly used in existing technologies has a significant drawback: the cut edge of the piping strip is straight. When this straight edge is subsequently sewn onto the seat fabric, the boundary line where it contacts the fabric is a continuous straight line, resulting in relatively concentrated stress. During use, especially in areas where the seat edges are frequently subjected to friction and pulling, the yarn or fibers at the edge of the piping strip are very prone to loosening and unraveling, i.e., "thread breakage." This not only seriously affects the aesthetic appearance of the finished seat and lowers the perceived quality of the product, but more importantly, it weakens the protective and reinforcing effect of the piping strip on the seat edges, shortening the lifespan of the seat. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fixed-length cutting and processing equipment for multi-specification seat piping strips, aiming to improve the problem of piping strips that are easy to loosen and break when cut in a straight line.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixed-length cutting and processing equipment for multi-specification seat hem strips, comprising a machine base, an operating table fixedly connected to the outer wall of the machine base, a connecting frame fixedly connected to the outer wall of the machine base, a wave cutting component disposed inside the connecting frame, a connecting column fixedly connected to the outer wall of the machine base, an adjusting component disposed inside the connecting column, and multiple conveyor belts disposed on the outer wall of the machine base; The wave cutting assembly includes a hot cutting blade, a connecting plate is slidably connected to the inner wall of the connecting frame, the hot cutting blade is fixedly connected to the inner wall of the connecting plate, a sliding groove plate is fixedly connected to one end of the connecting plate, a disc is provided inside the connecting plate, an eccentric shaft is fixedly connected to the upper surface of the disc, and the outer wall of the eccentric shaft is slidably connected to the inner wall of the sliding groove plate.

[0007] Furthermore, the adjusting assembly includes a rack and a gear, the outer wall of the rack is slidably connected to the inner wall of the connecting column, the gear is disposed inside the connecting column, the rack and the gear are meshed together, a connecting block is fixedly connected to the outer wall of the rack, and a feed roller is rotatably connected to the outer wall of the connecting block.

[0008] Furthermore, a sliding rod is fixedly connected to the inner wall of the connecting column, the inner wall of the connecting block is slidably connected to the outer wall of the sliding rod, and a second conveyor belt is provided on the outer wall of the connecting column, which is located below the feed roller.

[0009] Furthermore, a drive shaft is fixedly connected to the outer wall of the gear, a handwheel is fixedly connected to one end of the drive shaft, a gear disc is fixedly connected to the outer wall of the drive shaft, a second connecting block is fixedly connected to the outer wall of the connecting column, and a handle is slidably connected to the inner wall of the second connecting block.

[0010] Furthermore, a locking tooth is fixedly connected to one end of the handle, and the locking tooth engages with the gear plate. A spring is sleeved on the outer wall of the handle, one end of the spring is fixedly connected to the lower surface of the connecting block three, and the other end of the spring is fixedly connected to the upper surface of the locking tooth.

[0011] Furthermore, a sliding rail is provided through the inside of the connecting plate, a limit rod is fixedly connected to the inner wall of the connecting frame, and the outer wall of the sliding rail is slidably connected to the inner wall of the limit rod.

[0012] Furthermore, a motor is installed inside the connecting frame, and the output end of the motor is fixedly connected to the inner wall of the disc.

[0013] Furthermore, a drive frame is fixedly connected to the outer wall of the operating table, a fixed frame is fixedly connected to the outer wall of the operating table, and a cutting blade is provided on the lower surface of the drive frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the disc to rotate, which in turn drives the eccentric shaft to make circular motion in the slide plate, forcing the connecting plate to slide back and forth along the inner wall of the connecting frame, thereby driving the hot cutting blade to form a continuous wave trajectory cutting action. This motion mode produces a wave-shaped edge sealing structure on the edge strip cutting surface, effectively improving the tensile strength and aesthetics of the material edge, while avoiding the edge delamination problem caused by traditional straight cutting. During operation, only the motor needs to be started to automatically complete the wave cutting, significantly improving processing efficiency and cutting quality consistency. 2. In this utility model, a handwheel-driven gear and rack linkage mechanism is adopted. By rotating the handwheel, the gear is driven to rotate, and the meshing rack moves vertically along the slide bar, thereby adjusting the gap between the feed roller and the second conveyor belt. After adjustment, the hand lever is released, and the spring pushes the locking teeth to mesh and lock with the gear plate, ensuring the stability of the feed roller height. This design can quickly adapt to the edge strips of different thicknesses. During operation, only the hand lever needs to be released to automatically lock, which greatly simplifies the process of switching between multiple specifications of materials and avoids the cumbersome operation and loosening risk of traditional bolt adjustment.
