Description

Technical Field

[0001] The present invention relates to the technical field of garment processing, and particularly to an inverted hemming and welt seam drawbar. Background Art

[0002] In garment hemming, common drawbars include four-fold hemming, three-fold hemming, and double-fold hemming. For these relatively common and conventional processes, we must develop more novel processes to meet various production requirements. Among them, the inverted hemming process usually needs to be completed by manual ironing and then sewn with a flat-seam sewing machine. Undoubtedly, the efficiency is low, the speed is slow, and it is not suitable for mass production. Therefore, there is a need for improvement. Summary of the Invention

[0003] The present invention provides an inverted hemming and welt seam drawbar that can greatly increase work efficiency, can complete the processing and production of the inverted hemming process, improve the quality of finished products, and reduce manual operation and costs, solving the technical problems existing in the prior art that the current drawbar structure is relatively conventional, cannot be applied to the inverted hemming process, has low efficiency and slow speed during production, is not suitable for large-scale processing, and cannot meet more production requirements.

[0004] The above technical problems of the present invention are solved by the following technical solutions: An inverted hemming and welt seam drawbar includes a drawbar main body with multiple bends. The front end of the drawbar main body is the feeding end, and the rear end is the discharging end. On one side of the feeding end of the drawbar main body, there are multiple bends of guide rods. The size of the drawbar main body gradually decreases from the feeding end to the discharging end. The drawbar main body is a three-section smooth bending structure. A cover plate is fixedly provided on the right side of the drawbar main body, and there is a feeding gap between the cover plate and the drawbar main body. A positioning plate is fixedly provided at the front end of the drawbar main body. A baffle extending in the front and rear directions is integrally formed on the positioning plate. A detachable mounting plate is provided on the positioning plate, and there are several adjustment positioning grooves on the mounting plate. When in use, first fix the drawbar main body on the surface of the sewing machine. The drawbar main body is installed perpendicular to the surface of the sewing machine. Thread the hemming fabric into the feeding gap from the feeding end. The role of the guide rod is to ensure the flatness of the hemming fabric during feeding. The hemming fabric exits from the feeding gap to the discharging end. Under the action of the drawbar main body and the cover plate, the hemming fabric will be deformed into a vertically folded three-section bent fabric, forming an inverted hemming process. At the same time, place the fabric into the groove in the middle of the left side of the drawbar main body. During the processing, the fabric will be clamped in the middle of the hemming fabric, and finally the two can be directly sewn together. The baffle extends towards the discharging end at the rear side to ensure that the hemming fabric is not affected by other factors and completes the inverted hemming. The role of the positioning plate is to facilitate the quick positioning and installation of the drawbar main body. The positioning plate and the mounting plate are fixedly installed by bolts. The positioning plate can be freely detached from the mounting plate. The mounting plate is installed on the sewing machine, and the two cooperate to quickly install and position the drawbar main body.

[0005] Preferably, the cross-section of the main body of the draw tube is a W-shaped main body structure bent in three sections, and the inner wall of the draw tube main body is smooth. The smooth inner wall of the draw tube main body can prevent the edge-sealing fabric from being scratched, and the edge-sealing fabric can be smoothly bent and deformed along with the structure of the draw tube main body.

[0006] Preferably, a guide plate is provided on the left side of the main body of the draw tube. During operation, the fabric is placed in the groove in the middle of the left side of the main body of the draw tube. During the processing, the fabric will be clamped in the middle of the edge-sealing fabric, and the guide plate can play a role in supporting and guiding to ensure that the fabric is always located in the groove in the middle of the left side of the main body of the draw tube.

[0007] Preferably, the guide plate is located below the chute in the middle of the left side of the main body of the draw tube. The main function of the guide plate is to support and position, so the position of the guide plate cannot be higher than the chute in the middle of the left side of the main body of the draw tube and needs to be located below the chute in the middle of the left side of the main body of the draw tube.

[0008] Preferably, the edge of the guide plate is smoothly bent downward. Since the fabric will also be continuously conveyed to the discharge end for processing along with the edge-sealing fabric, if the edge of the guide plate is not smooth, it will scratch the fabric and affect the finished product. In the present utility model, the edge of the guide plate is smoothly bent downward, which can avoid scratching the fabric and ensure the quality of the finished product.

[0009] Preferably, a plurality of operation openings are spaced apart on the cover plate. The function of the operation openings is to facilitate using tools to quickly pass the edge-sealing fabric through the feeding gap of the main body of the draw tube and lead it out from the discharge opening before processing.

[0010] Preferably, the edge on one side of the main body of the draw tube near the feeding end is smoothly bent to the left. Along with the processing, the edge-sealing fabric will continuously output from the feeding end to the discharge end. If the front edge of the main body of the draw tube is not smooth, it is easy to scratch the edge-sealing fabric and affect the quality of the finished product. In the present utility model, the front edge of the main body of the draw tube is smoothly bent to the left, which can avoid scratching the edge-sealing fabric and ensure the quality of the finished product.

[0011] Therefore, a reverse edge-sealing and raw edge stop draw tube of the present invention has the following advantages: it can greatly improve the working efficiency, can complete the processing and production of the reverse edge-sealing process, the overall structural layout is reasonable, it can effectively improve the quality of the finished product, and reduce manual operation and costs.
