Technical Field
[0001] This utility model relates to the field of garment processing equipment technology, and in particular to an automatic folding and sewing device for multi-slot waist clips. Background Technology
[0002] In the garment manufacturing industry, especially in the production of trousers or skirts, the sewing of waistbands is a crucial step. Before sewing, waistbands typically need to be folded in half to ensure their aesthetic appeal and structural strength. Currently, the folding and alignment of waistbands with the main fabric are primarily done manually by production line workers. Workers must pick one waistband from a pile of pre-cut pieces, fold it manually, and then place it under the sewing machine to align it with the main fabric for sewing. This purely manual operation method is extremely slow, its processing speed entirely dependent on the worker's skill level and labor intensity, resulting in low production efficiency and difficulty in meeting current needs. The pace of modern, large-scale garment production demands high efficiency, but also results in high labor costs. Due to the inherent randomness of manual folding and positioning, slight deviations can occur between different workers or even within the same worker at different times. This leads to inconsistent folding lines and inaccurate stitching in the final product, severely impacting the standardization and appearance quality of the product and increasing the defect rate. Furthermore, when the production line needs to handle orders for garments of different sizes, workers need to frequently change waist clip materials of different specifications. Manual sorting and switching are not only prone to errors but also further reduce the overall operating efficiency and flexibility of the production line.
[0003] Therefore, this utility model proposes an automatic folding and sewing device for multi-slot waist cards to overcome the shortcomings of the prior art. Utility Model Content

[0005] This utility model provides an automatic folding and sewing device for multi-slot waist clips, including a sewing machine body, a support frame, a feeding device, a waist clip transfer and folding device, a waist clip transfer and rotation device, and a positioning device. The feeding device, waist clip transfer and folding device, waist clip transfer and rotation device, and positioning device are all organically integrated around the sewing machine body via their respective bases. Furthermore, the feeding device, waist clip transfer and folding device, waist clip transfer and rotation device, and positioning device form a sequentially connected automated processing workstation, which, through coordinated cooperation, constitutes a complete automated structural layout from material supply, folding, posture adjustment and conveying to final positioning.

[0022] Working principle: When the operator selects the desired waist card size through the control panel 7 and starts the equipment, the control mechanism 6 receives the instruction and begins to coordinate the various devices for automated operation. First, the control mechanism 6 controls the start of the moving motor 304 in the feeding device 3. The moving motor 304, through meshing with the gear rack 306, drives the transverse transfer module 302 to slide precisely laterally along the fixed slide rail 305 until the waist card slot 307 storing the target size waist card moves to the preset feeding position. After positioning, the control mechanism 6 drives the feeding motor 308, which drives the lead screw 309 to rotate. Since the pushing module 310 is threadedly engaged with the lead screw 309 and slidably connected along the slide rail 311, the pushing module 310 then... Driven by lever 309, the device moves smoothly upwards vertically, pushing the topmost waist clip out of the waist clip slot 307 to the gripping position. Then, control mechanism 6 controls the waist clip transfer and folding device 4 to operate. Output motor 406 drives support moving plate 402 to move along slide rail 404, causing the picking cylinder 407 and its end-mounted picking vacuum pump 408, mounted on support moving plate 402, to move directly above the waist clip to be gripped. Picking cylinder 407 moves downwards, and picking vacuum pump 408 generates negative pressure to attract the waist clip. Picking cylinder 407 then returns to its original position upwards, and output motor 406 reverses, driving support moving plate 402 to move the picking vacuum pump 408, which holds the waist clip, above folding baffle 405. Picking vacuum pump 408 then releases negative pressure. The waist clip is placed flat on the folding baffle 405. Then, the folding cylinder 409 drives the folding push plate 410 downwards, precisely pressing the waist clip into the folding groove on the folding baffle 405, thus completing the automatic folding of the waist clip. After folding, the control mechanism 6 activates the waist clip transfer and rotation device 5. The horizontal motor 509 drives the left and right moving plates 503 to move along the long slide rail 508, causing the clamping cylinder 512 mounted on the left and right moving plates 503 to move to the folded waist clip and clamp it. Then, the horizontal motor 509 drives the left and right moving plates 503 to move in the opposite direction, while the output motor 506 drives the front and rear moving plates 502 to move along the slide rail 504. The rotary motor 510, connected by the motor connecting seat 511, drives the clamping cylinder. Cylinder 512 rotates 90 degrees, and through this series of compound movements in three-dimensional space, the folded and correctly positioned waist clip is precisely transferred to the positioning device 2 on the sewing machine body 1. After the waist clip arrives, the clamping cylinder 512 releases, and the control mechanism 6 immediately drives the forward pushing cylinder 202 and the downward pressing cylinder 204 on the positioning device 2. The forward pushing cylinder 202 pushes the forward pushing baffle 203 to perform lateral positioning of the waist clip, while the downward pressing cylinder 204 drives the downward pressing baffle 205 to vertically press and fix the waist clip. At this point, the automatic processing of the waist clip is completed, and it is ready to be sewn with the main fabric. The whole process realizes fully automatic, high-precision, and high-efficiency processing of multi-size waist clips from feeding, folding to pre-sewing positioning, solving the inherent defects of manual operation.
