Description

Technical Field

[0001] This utility model relates to the field of punching technology for fabric products, and in particular to a pneumatic punching device for fabric products. Background Technology

[0002] Fabric products, as a key material widely used in packaging, medical, and industrial insulation fields, often require punching processes to impart specific functions such as breathability, filtration, or patterning. Among various punching processes, pneumatic punching technology has become an important method for achieving efficient and high-quality processing due to its fast response speed, strong impact force, and precise control. This technology typically uses a cylinder to drive a die to punch the material instantaneously, effectively ensuring the neatness and consistency of the hole edges, and is particularly suitable for the mass production of continuous roll materials.

[0003] However, under current technological conditions, many devices lack effective tension coordination control in the feeding and winding sections, causing the film to easily stretch or wrinkle due to tension fluctuations during transport, directly affecting the accuracy of the punching position. On the other hand, existing devices often fail to fully coordinate the feeding, punching, and winding actions, with each unit operating independently. This not only affects overall production efficiency but also makes it difficult to ensure the uniformity and stability of the punching spacing, thus hindering further improvements in product quality.

[0004] Therefore, there is an urgent need for a pneumatic punching device for fabric products. Utility Model Content

Detailed Implementation

[0020] Example: A pneumatic punching device for fabric products, such as Figures 1-5As shown, the system includes a base 1, a motor 11, a magnetic powder brake 12, a feeding roller 13, a conveying roller 14, a first synchronous pulley set 15, a detection roller 16, a controller 17, a mounting frame 3, a cylinder 31, an upper mold 32, a lower mold 33, a support frame 5, a second motor 51, a conveying roller 52, a second synchronous pulley set 53, a collecting roller 54, and a third synchronous pulley set 55. The motor 11 is mounted on the front left side of the base 1 with screws. The magnetic powder brake 12 is fixedly connected to the right end of the output shaft of the motor 11. The feeding roller 13 is fixedly connected to the right end of the magnetic powder brake 12. The feeding roller 13 is made of stainless steel. A detection roller 16 is mounted on the base 1 at the rear of the feeding roller 13. A conveying roller 14 is rotatably connected to the base 1 at the rear of the detection roller 16. A first synchronous pulley set 15 is provided between the conveying roller 14 and the output shaft of the motor 11. A controller 17 is mounted on the side by screws. A mounting bracket 3 is fixedly mounted in the middle of the base 1. A cylinder 31 is mounted on the top of the mounting bracket 3 by screws. The piston rod of the cylinder 31 is connected to the upper mold 32 by screws. A lower mold 33 is mounted on the top of the base 1 vertically corresponding to the upper mold 32 by screws. A support frame 5 is fixedly mounted on the middle and rear side of the base 1. A second motor 51 is fixedly mounted on the left side of the middle and rear part of the base 1. A conveying roller 52 is connected in a vertically distributed rotatable manner inside the support frame 5. A second synchronous wheel set 53 is provided between the left sides of the conveying roller 52. The output shaft end of the second motor 51 is connected to the second synchronous wheel set 53. A collecting roller 54 is fixedly mounted on the top and rear side of the base 1. A third synchronous wheel set 55 is provided between the left end of the collecting roller 54 and the output shaft of the second motor 51. The controller 17 is electrically connected to the first motor 11, the magnetic powder brake 12, the detection roller 16, and the cylinder 31.

[0021] like Figure 1 and Figure 5 As shown, it also includes a knob 2. The right side of the feeding roller 13 and the collecting roller 54 are both threaded with knob 2, which facilitates quick loading and unloading of material rolls and improves operating efficiency.

[0022] like Figure 4 As shown, it also includes a slide bar 34 and a spring 35. The top left and right sides of the lower mold 33 are provided with slide grooves. The bottom of each slide groove is fixedly connected with slide bars 34 in a front-to-back distributed manner. Each slide bar 34 is surrounded by a spring 35.

[0023] like Figure 4 As shown, it also includes a limiting block 36, and the sliding rods 34 are slidably connected to the limiting block 36 through a sliding groove. The springs 35 are all connected between the lower mold 33 and the limiting block 36.

[0024] like Figure 3As shown, it also includes a second slide rod 4 and a second spring 41. The upper mold 32 and the lower mold 33 are slidably connected by slide rods 4 through slide grooves, which play a guiding and positioning role to ensure that the upper mold 32 and the lower mold 33 are accurately aligned. The slide rods 4 are all surrounded by second springs 41, which are connected between the upper mold 32 and the lower mold 33. They can provide a rebound force after punching, so that the upper mold 32 can quickly return to its original position and effectively prevent the film from sticking.

[0025] Before using this device, first unscrew the knob 2 on the right side of the unloading roller 13, place the roll of fabric to be processed onto the unloading roller 13, and then tighten the knob 2 again to secure the roll. After loading, start the controller 17, which will sequentially turn on the motor 11 and the magnetic powder brake 12. The motor 11 drives the feeding roller 14 to rotate at a constant speed through the synchronous pulley set 15, realizing the forward conveying of the fabric; at the same time, the magnetic powder brake 12 applies controllable resistance to the unloading roller 13, so that the fabric maintains appropriate tension during unwinding and avoids loosening or overstretching. After the fabric is drawn out from the unloading roller 13, it passes around the detection roller 16 and continues to be conveyed forward. The detection roller 16 detects the fabric tension in real time and feeds the signal back to the controller 17. The controller 17 dynamically adjusts the resistance of the magnetic powder brake 12 according to the preset tension parameters, thereby maintaining the stability of the fabric tension throughout the feeding process. When the fabric is conveyed to the processing area between the upper mold 32 and the lower mold 33, the controller 17 commands the cylinder 31 to operate. The piston rod of cylinder 31 pushes the upper mold 32 downward, cooperating with the lower mold 33 to complete the punching process on the fabric. The sliding rods 4 distributed around the molds act as guides and positions, ensuring accurate alignment of the upper and lower molds 33. Spring 41 provides a restoring force after punching, allowing the upper mold 32 to quickly return to its original position, effectively preventing the fabric from sticking. Simultaneously, the limiting block 36, under the action of spring 35, laterally limits the fabric, preventing it from shifting during transport and ensuring accurate hole positioning. During punching, the upper mold 32 presses down, acting on the fabric and pressing the limiting block 36, causing it to slide down the sliding rod 34 and compress spring 35. After the upper mold 32 disengages, it returns to its original position under the restoring force of spring 41. At the same time, the limiting block 36 rises to its initial position under the restoring force of spring 35, re-limiting the fabric laterally.

[0026] After the punching process is completed, controller 17 starts motor 51. Motor 51 drives the feed roller 52 in the support frame 5 to rotate synchronously through synchronous pulley set 53, smoothly pulling the punched film backward and finally guiding it to the collecting roller 54 for winding and storage. The collecting roller 54 is connected to the output shaft of motor 51 through synchronous pulley set 55 to ensure that the winding speed is synchronized with the feed roller 52 and maintain the continuous and stable tension of the system. In addition, both the unloading roller 13 and the collecting roller 54 are equipped with knob 2 structures on the right side for quick loading and unloading of the roll, improving operating efficiency. After all processing operations are completed, the controller 17 sequentially shuts down the actuators such as motor 11, magnetic powder brake 12, cylinder 31, and motor 51 to achieve a safe shutdown.
