Description

Technical Field

[0001] This utility model relates to the field of elastic band processing technology, and in particular to a positioning mechanism for elastic band processing. Background Technology

[0002] Elastic bands are key accessories in clothing, medical supplies, and other fields, and their processing precision directly affects the comfort and functionality of the final product. In traditional elastic band processing, due to the material's high elasticity and easy deformation, positioning deviations are prone to occur during cutting and printing processes, leading to uneven product lengths and misaligned seams. Especially in high-speed automated production scenarios, achieving stable conveying and precise positioning of elastic bands has become a core technical challenge restricting product quality and production efficiency.

[0003] Currently, the industry commonly uses mechanical guide roller assemblies or fixed limit blocks for elastic band positioning. The underlying technology relies primarily on physical contact constraints. The elastic band is held between upper and lower rubber rollers, and the conveying path is controlled by rolling friction. Fixed-distance metal baffles are installed on both sides of the cutting station to forcibly constrain the lateral movement of the material. Floating rollers, pressed by counterweights or cylinders, maintain material tension. All these solutions require manual adjustment of component positions to accommodate different elastic band specifications.

[0004] However, the aforementioned technologies suffer from a significant drawback: insufficient cutting precision. Due to the lack of dynamic correction capabilities and elastic material adaptation mechanisms, the fixed structure cannot compensate in real time when the elastic band experiences slight shifts due to internal stress or external friction. This results in substantial errors in cutting length, failing to meet the stringent precision requirements of high-end medical bandages, sportswear, and other applications. This pain point directly leads to persistently high material waste and product rework rates. Utility Model Content

The feeding roller 30 is set below the cutting mechanism 3. The fixed shaft 17 is set above the slider 16.

[0021] Working principle: First, the elastic band is passed through the feeding roller 5, then placed in the groove of the V-groove shaft 29. The elastic band is then pulled further onto the worktable 1, passing through the guide plate 18, the feeding roller 30, and below the cutting mechanism 3. At this point, the cutting length and other data are set on the display screen 7. Then, the fixed shaft 17 is pulled, causing the connecting rod 23 to slide to the appropriate width. Rotating the fixed shaft 17 causes it to press against the isolation shaft 20, creating friction on the slider 14 and fixing the positioning assembly. Finally, rotating the threaded rod 12 pushes the slider 21, releasing the spring 19 from its pressing state. The state begins to open, and the slider 4 22 drives the guide plate 18 to begin to contract. When it reaches a certain width, the threaded rod 12 stops rotating to achieve the positioning effect. Then, the motor 6 is started on the display screen 2 8. The motor 6 drives the track 9 to rotate, the track 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the feeding roller 5 to rotate. The elastic band then begins to be conveyed. When it passes the V-groove shaft 29, the V-groove shaft 29 begins to rotate to reduce the friction between it and the elastic band. According to the previously adjusted guide, the elastic band is continuously sent to the bottom of the cutting mechanism 3. The cutting mechanism 3 cuts the elastic band below it evenly according to the set length.
