[0002] After searching, the patent with publication number CN215750331 U discloses a trimming device for chemical fiber cloth processing. When the device is used, on the one hand, the user can place one end of the cloth to be trimmed on the second storage table, and then start the hydraulic telescopic rod on the second pressing plate to drive the second pressing plate to press the cloth tightly, and when the cloth is pressed and fixed, the limiting needle on the second pressing plate will pierce the cloth and be stuck in the inside of the socket on the second storage table, thereby improving the fixing performance of the device for the cloth by adding a needle limiting structure to the pressing and fixing structure, and reducing the loosening of the cloth during trimming. On the other hand, starting the hydraulic telescopic rod can drive the second pressing plate and the first pressing plate to move up and down, thereby realizing automatic fixation of the cloth to be trimmed, thereby optimizing the fixing effect through the double-layer pressing and fixing structure.

[0003] The above-mentioned device realizes automatic fixation of the cloth to be trimmed by moving the second pressing plate and the first pressing plate up and down, and adding a needle-punching limit structure. However, cloths of different materials have different sensitivities to the needles. When the needles pierce the cloth for reinforcement, the cloth will be damaged.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Polyester fabric trimming machine is a kind of equipment specially used for processing the edge of polyester fabric. It is usually used to trim and finish polyester fabric to ensure that the edge of the fabric is neat and free of messy fibers, thereby improving the appearance and quality of the fabric.

[0024] Existing devices automatically secure the fabric to be trimmed by moving the second and first pressing plates up and down, and adding a needle-punching stopper. However, different fabrics have different sensitivities to the needles, and the needles can damage the fabric when piercing it for reinforcement. This is mainly due to the needles being too sharp or of inappropriate size. When penetrating the fabric, especially polyester fabric, they can tear or cut the fibers, thereby damaging the overall fabric structure. Figures 1-4 This embodiment provides a polyester cloth processing and trimming machine, including a frame 1 and a bottom plate 2 and a pressing plate 3 arranged on the top of the frame 1. The frame 1 is the supporting frame of the entire structure, the bottom plate 2 is located on the top of the frame 1, and the pressing plate 3 is arranged above the bottom plate 2. When the cloth is placed on the top of the bottom plate 2, the pressing plate 3 will apply pressure downward from the top to fix the cloth on the bottom plate 2. The purpose of this design is to ensure that the cloth remains flat during the processing. Through the cooperation of the frame 1, the bottom plate 2 and the pressing plate 3, the cloth can be stably trimmed in the operating area of ​​the frame 1.

[0025] The opposite sides of the base plate 2 and the pressing plate 3 are fixedly connected with plush rubber plates, and the plush rubber plates are plate-like structures with flocked upper surfaces made of rubber. The flocked surface has good flexible contact and anti-slip properties, which effectively avoids wear or damage caused by friction and extrusion during the fixing process of the cloth, protects the integrity of the cloth, and effectively prevents the cloth from sliding or deflecting during the process of being clamped by the base plate 2 and the pressing plate 3.

[0026] refer to Figures 1-4As shown, the existing device realizes automatic fixation of the cloth to be trimmed by moving the second pressing plate and the first pressing plate up and down, and adding a needle-punching limit structure. However, different materials of cloth have different sensitivities to the needles. When the needles pierce the cloth for reinforcement, the cloth will be damaged. The main reason is that the tip of the needle is too sharp or the size is not appropriate. When it penetrates the cloth, especially polyester cloth, it will cause the cloth fibers to tear or cut, thereby damaging the overall structure of the cloth. In order to fix the cloth without damaging the overall structure of the cloth, the following settings are made: a fixing component 4 is provided on the side of the frame 1 to drive the pressing plate 3 to move downward to press the cloth. The fixing component 4 includes a lifting rod 45 provided on the top of the pressing plate 3. The side of the frame 1 is provided with a power assembly that enables the lifting rod 45 to drive the pressure plate 3 to move toward the base plate 2. The power assembly includes a handle 41 that rotates on the side of the frame 1. The inner wall of the handle 41 is fixedly connected to a bidirectional threaded screw 42. The outer wall of the bidirectional threaded screw 42 is threadedly connected to two driving blocks 43. The tops of the two driving blocks 43 are movably connected to a movable rod 44. The movable rod 44 is hinged to the bottom of the lifting rod 45. After placing the cloth on the top of the base plate 2, the handle 41 is rotated to make the two driving blocks 43 on the outer walls of the bidirectional threaded screw 42 displaced away from each other. The away-to-away displacement of the two driving blocks 43 gradually expands the angle between the movable rods 44, thereby causing the lifting rod 45 to drive the pressure plate 3 to move downward to fix the cloth. The top of the pressing plate 3 is provided with a cloth tightening assembly 46 for flattening the cloth after the bottom plate 2 and the pressing plate 3 are clamped. The cloth tightening assembly 46 includes a driving rod 461 hinged on the end face of the lifting rod 45. The driving rod 461 is movably connected to a mounting plate 462 at one end away from the lifting rod 45. The bottom of the mounting plate 462 is symmetrically fixedly connected to two insertion rods 463. Two detachable columnar tubes 467 for the two insertion rods 463 to be inserted are fixedly connected to the bottom of the bottom plate 2. After the cloth is fixed, the two insertion rods 463 are Inserted into the two cylindrical tubes 467, the continuous descent of the lifting rod 45 causes the driving rod 461 to push the mounting plate 462 and its bottom base plate 2 to slide synchronously with the pressing plate 3, thereby flattening the cloth clamped between the base plate 2 and the pressing plate 3, ensuring that the cloth maintains a stable position and tension during the trimming cutting or processing process, thereby ensuring that the edge lines of the trimming are neat and regular, and by flattening the two ends of the cloth, irregular movement of the cloth can be effectively prevented, ensuring that the cloth remains flat during the trimming process. The pressure plate 3 is slidably sleeved on the outer walls of the two insertion rods 463. Both insertion rods 463 are provided with a limiting assembly that allows the pressure plate 3 to slide in a directional manner along its outer wall. The limiting assembly includes a limiting ring 465 fixed on the outer wall of the insertion rod 463. The top of the limiting ring 465 contacts the bottom of the pressure plate 3. A circular groove 466 is provided on the top of the base plate 2. The limiting ring 465 is clamped in the circular groove 466 to limit the position and is detachable. The limiting ring 465 is clamped in the circular groove 466 to limit the insertion rod 463, so that the cloth tightening assembly 46 can achieve a driving effect.The outer wall of the insertion rod 463 is provided with a compression spring 464, and the two ends of the compression spring 464 are fixedly connected to the mounting plate 462 and the pressure plate 3 respectively. After the limiting ring 465 is clamped in the annular groove 466, the pressure plate 3 further clamps and fixes the cloth through the compression spring 464 to prevent the cloth from causing errors due to position movement or loosening, thereby ensuring the accuracy and consistency of trimming. The pressure plate 3 is connected to the lifting rod 45 through the cloth tightening component 46.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
