Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garment production, in particular to an automatic elastic band connecting device. BACKGROUND

[0002] The automatic elastic band connecting device is a special device for automatically cutting, splicing, collecting and sorting whole rolls of elastic bands, which is widely used in the garment manufacturing industry, especially for producing circular elastic bands required for garment cuffs, ankle openings, hems, waistbands, waistbands, etc. The automatic elastic band connecting device significantly improves the efficiency and quality of elastic band production through highly automated and intelligent design, and is an indispensable important device in the modern garment manufacturing industry.

[0003] The common automatic elastic band connecting device usually needs manual positioning of the elastic band during feeding and conveying. Manual operation cannot guarantee that the position and force of each positioning are completely consistent, which may cause unstable processing quality of the elastic band and affect the quality of the final product. At the same time, the structure of the driving control frame is exposed and has many parts, which is easy to be damaged, causing certain adverse effects on the use process. Therefore, we propose an automatic elastic band connecting device. SUMMARY

[0004] The technical problem solved by the present application is that the automatic elastic band connecting device provided by the present application has the advantages of improving product quality, improving production efficiency, and protection. The second control motor drives the second rotating rod to drive the first bevel gear to rotate. The first bevel gear and the second bevel gear are mutually engaged and transmitted. The third rotating rod on the inner wall of the second bevel gear drives the adjusting screw rod to rotate on the inner side of the adjusting groove, so that the moving block moves on the outer wall of the adjusting screw rod, thereby driving the movable limiting plate to move. This can reduce manual intervention and make the feeding and conveying process more continuous and efficient, thereby improving the overall production efficiency. At the same time, the position and tension of the elastic band can be more accurately controlled, thereby ensuring the quality and consistency of the product. The detachable protective cover is positioned at the front end of the driving control frame, which can protect the structure of the driving control frame. The cross frame supports the inner side of the inner heat dissipation port to stabilize the position. The first control motor drives the first rotating rod to drive the rotating disc and the cooling fan to rotate together. This can strengthen air circulation and heat dissipation on the inner side of the dustproof screen, effectively solving the problems in the background art.

[0035] Working Principle: An automatic tensioning device. During use, the elastic band is conveyed into the inner side of the heating chamber rack 7 via the first transmission wheel 6 and the second transmission wheel 9 for heating, achieving a smooth ironing effect. Both the first transmission wheel 6 and the second transmission wheel 9 are driven to rotate by a motor. The movable door 8 can be opened and closed via a hinge, facilitating maintenance and adjustment of the inner side of the heating chamber rack 7. The heating transmission controller 5 can control the adjustment of the heating chamber rack 7. The elastic band then passes through the lower end of the heating chamber rack 7 and is laid on the upper end of the transmission worktable 2 via the third transmission wheel 11. It is limited by the movable limit plate 10. The movable block 52 connected to the lower end of the movable limit plate 10 is sleeved on the outer wall of the adjusting threaded rod 51 through the threaded hole 53, so that the movable limit plate 10... The 0 is positioned on both sides of the upper end of the transmission workbench 2. Adjustment control frames 42 are fixedly connected to both sides of the transmission workbench 2, facilitating the adjustment of the two sets of movable limit plates 10. Fixed plates 45 provide support and stability on the inner wall of the adjustment control frame 42. The second control motor 46 drives the second rotating rod 47 to rotate the first helical gear 48. The first helical gear 48 and the second helical gear 50 mesh and transmit power. The third rotating rod 49 on the inner wall of the second helical gear 50 drives the adjusting threaded rod 51 to rotate inside the adjusting groove 43, causing the moving block 52 to move on the outer wall of the adjusting threaded rod 51, thereby moving the movable limit plates 10. This reduces manual intervention and limits the elastic band laid on the upper end of the transmission workbench 2, allowing the upper... The material conveying process is more continuous and efficient, thereby improving overall production efficiency. Simultaneously, the position and tension of the elastic band can be more precisely controlled, ensuring product quality and consistency. The fourth transmission wheel 12 is driven to rotate by a motor, and the elastic band is then conveyed through the fourth transmission wheel 12. After passing through the lower end of the cutting blade 14, the sewing worktable 1, controlled by the main controller 15, drives the telescopic clamp 21 to move back and forth. The telescopic clamp 21, driven by a cylinder, clamps and pulls the elastic band, laying it on the upper end of the positioning plate 25. Simultaneously, the cutting blade controller 13 drives the cutting blade 14 to cut it to the appropriate size. The two ends of the cut elastic band are clamped and flipped by the flipping clamp 24, laying the two ends of the elastic band on the positioning plate. At the upper end of 25, the positioning plate 25 is controlled to move back and forth by the drive device at the rear end of the drive control frame 23. The positioned elastic band is placed at the lower end of the compactor 19 for pressing. Then, the two ends of the elastic band are sewn and positioned by the sewing control head 20. After sewing, the finished product is pushed forward by the pusher 18 to be discharged into the collection box. The drive device and wires installed at the rear end of the drive control frame 23 are numerous. The protective effect is enhanced by the detachable protective cover 26, which also has a certain heat dissipation effect. The insertion block 30 connected to the detachable protective cover 26 is inserted into the inner side of the insertion hole 28. The positioning block 34 is locked into the inner side of the positioning hole 29 by the action of its rear damping elastic element 33 for positioning.The detachable protective cover 26 is positioned at the front end of the drive control frame 23, providing protection for the structural equipment on the drive control frame 23. The cross 37 provides support and stability inside the inner heat dissipation vent 35. The first control motor 38 drives the first rotating rod 39, causing the turntable 40 and cooling fan 41 to rotate together, which enhances airflow and heat dissipation inside the heat dissipation dustproof mesh 36. The heat dissipation dustproof mesh 36 is threadedly positioned at the front end of the inner wall of the inner heat dissipation vent 35, providing dust prevention and ventilation.
