Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fastener production, in particular to a stripping device for hook and loop fastener production. Background Art

[0002] Velcro, also known as hook and loop fasteners, is a type of tape made of two different materials and widely used in various fields. The production process typically includes multiple steps, such as raw material preparation, yarn manufacturing, webbing, brushing, hook surface manufacturing, heat treatment, dyeing and finishing, quality inspection, packaging, and storage. Slitting is a key step in the production process. Slitting is crucial in Velcro production, as it meets market demand for different widths and specifications, improving product adaptability and market competitiveness.

[0003] Common slitting equipment for hook and loop fastener production typically consists of a support system, a traction system, a slitting mechanism, a control system, safety devices, and other auxiliary equipment. The hook and loop fastener is first placed on the support system, and the traction system then pulls the material to be slit. The slitting mechanism cuts the wide web into products of the desired width. The control system enables automated operation and precise control, and safety devices such as emergency stop buttons and protective covers quickly cut off power in emergencies.

[0004] In traditional Velcro production slitting equipment, dust is generated when the cutting knife cuts the Velcro. At the same time, when dust adheres to the cutting knife, the sharpness of the cutting edge is reduced, which not only pollutes the environment, but also reduces the cutting effect. In order to solve the above problems, some Velcro production slitting equipment is equipped with a suction fan and a suction head. At the same time, the suction heads are evenly installed in multiple groups around the equipment. The suction fan generates suction force on the suction heads. When dust is generated by cutting, the suction heads absorb the dust and can transport it to the connected dust storage box, thereby ensuring that the environment is free from pollution and the cutting effect is achieved. However, in this method, since the air inlet end of the suction head is aligned with the Velcro, when the suction head generates suction, the Velcro will inevitably shake due to its light weight, making it impossible to ensure the accuracy and stability of the Velcro slitting operation. For this reason, a Velcro production slitting equipment is proposed. Utility Model Content

[0005] (1) Technical problems solved

[0006] In view of the deficiencies in the prior art, the present invention provides a slitting device for Velcro production to solve the above-mentioned technical problem that the accuracy and stability of the slitting operation of Velcro cannot be guaranteed.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a slitting device for producing hook and loop fasteners, comprising:

[0009] A workbench and retractable shafts are provided on both sides of the workbench. An adjustment assembly is provided directly above the top of the workbench, and a connecting seat is provided directly below the bottom of the adjustment assembly. A cutting blade is provided at the bottom of the connecting seat, and a fourth drive motor is coaxially connected to the end of the cutting blade.

[0010] The lifting duct is arranged on both sides of the top center of the connecting seat, and the bottom end of the lifting duct extends downward through the connecting seat and is connected to the suction head, and the top end of the lifting duct is connected to the suction fan;

[0011] Guide rods are arranged on both sides of the top of the connecting seat, and the surfaces of the guide rods are sleeved with extrusion springs. A lower connecting seat is installed at the bottom of the guide rods, and the inner cavity of the lower connecting seat is rotatably connected to a pressure column. After the Velcro is moved to the top of the workbench via the retractable shaft, the adjustment component drives the connecting seat to descend, so that the pressure column first contacts the surface of the Velcro. The fourth drive motor drives the cutting knife to rotate. When the connecting seat continues to descend, it squeezes the extrusion spring, and the cutting knife contacts the Velcro and strips the Velcro. The suction fan generates suction through the lifting duct to suck in dust and other substances, which can be transported by the suction fan to a storage device connected to the outside world. On the one hand, the downward pressure on the Velcro by the pressure column prevents the Velcro from being affected by the suction and shaking, ensuring the accuracy and stability of the Velcro stripping operation. On the other hand, the suction head is evenly installed around the cutting knife. When stripping, it can fully and timely absorb the dust generated, thereby ensuring the production quality of the Velcro.

[0012] Preferably, the retractable shaft is rotatably connected to the workbench, and a first drive motor is installed at the end of the retractable shaft. The first drive motor drives the retractable shaft to rotate on the workbench, thereby controlling the retracting and extending operation of the hook and loop fastener.

[0013] Preferably, the adjustment assembly includes a square frame plate, and a threaded screw is added at the front and rear ends of the inner cavity of the square frame plate, and a second drive motor is coaxially connected to the end of the threaded screw. The second drive motor drives the threaded screw to rotate on the square frame plate and adjusts the direction of the threaded screw.

[0014] Preferably, a sliding block is sleeved in the center of the threaded screw, and a U-shaped seat is mounted at the bottom of the sliding block. A bidirectional screw is connected to the inner cavity of the U-shaped seat, and a third drive motor is coaxially connected to the end of the bidirectional screw. The sliding block drives the U-shaped seat to move according to the rotation direction of the threaded screw, and the third drive motor drives the bidirectional screw on the U-shaped seat to rotate and adjust the rotation direction of the bidirectional screw.

[0015] Preferably, sliding plates are sleeved on both sides of the outer surface of the bidirectional screw, and hydraulic rods are mounted on the bottom of the sliding plates, and the hydraulic rods are connected to the connecting seats. The sliding plates drive the hydraulic rods and their connecting structure to move toward each other according to the rotation of the bidirectional screw, thereby adjusting the distance between the two sets of connecting seats and the cutting blades according to the size of the hook and loop fastener strips.

[0016] Preferably, side scrapers are provided on the upper sides of both sides of the cutting blade, and the side scrapers are located inside the suction head. The side scrapers are connected to the connecting seat, and the suction fans are installed on both sides of the sliding plate. When the cutting blade rotates to strip the hook and loop fastener, some residue will adhere to the surface of the cutting blade. The side scrapers scrape off the adhered residue, and the suction head can absorb the scraped residue. This not only ensures the quality of the stripping, but also facilitates the collection of the residue.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a slitting device for producing hook and loop fasteners, which has the following beneficial effects:

[0019] This Velcro production slitting equipment uses a retractable shaft to move the Velcro to the top of a workbench. An adjustment assembly then lowers the connecting seat, causing the pressure column to first contact the surface of the Velcro. A fourth drive motor then rotates the cutting blade. As the connecting seat continues to descend, it compresses the extrusion spring, causing the cutting blade to contact the Velcro and slit the tape. The pressure column initially presses down on the Velcro, preventing it from shaking due to suction, ensuring the precision and stability of the slitting process. A suction fan, through a lifting duct, generates suction in the material suction head, sucking in dust and other particles, which are then transported by the fan to a storage device connected to the outside world. The suction heads are evenly mounted around the cutting blade to fully absorb dust generated during slitting, thereby ensuring the quality of Velcro production. BRIEF DESCRIPTION OF THE DRAWINGS
