Curtain fabric composite transfer mechanism

Abstract

This utility model provides a curtain fabric composite joining mechanism, including a worktable. A take-up roller is provided on one side of the worktable, and a traction fabric is mounted on the take-up roller. One end of the traction fabric is fixed with a traction clamp. Side panels are provided on both sides of the worktable, and each side panel has a through-type, horizontal sliding groove. A slider is slidably connected within the sliding groove. A fixing clamp is provided on the side of the slider closest to the worktable, and the fixing clamp holds the two edges of the traction fabric. This curtain fabric composite joining mechanism, through the arrangement of the sliding groove, slider, and connecting beam, allows the slider to slide within the sliding groove under the drive of a stepper motor. The fixing clamp on the slider holds the edge of the traction fabric, and the slider pulls the traction fabric out, eliminating the need for manual pulling of the traction fabric by workers, greatly saving manpower. Simultaneously, the pressure of the pressure roller can be adjusted by an electromagnet to achieve better sewing results for different fabrics.

Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a composite handover mechanism for curtain fabrics. Background Technology

[0002] Fabric sewing is the process of joining two or more pieces of fabric together. Generally, a sewing machine is used for this, employing one or more sewing threads to create one or more stitches on the fabric, interweaving or sewing one or more layers of fabric together. However, for the production of large items like curtains, workers need to repeatedly pull the fabric manually, and the seams are sewn together using sewing components, increasing the workload for workers.

[0003] For example, in publication number CN222781789U, "A Fabric Sewing Device," clamps hold two pieces of fabric and their joining parts separately. A winding roller rotates to wind up the connecting fabric, pulling the fabric to move. The two pieces of fabric are flattened by a pressure roller, and then pressed together by a roller. Finally, a sewing assembly achieves precise sewing. However, it still requires pulling the connecting fabric to attach the clamps on it to the fabric to be sewn, and the connecting fabric must be pulled from one end of the worktable to the other, making the workload still quite high.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] This utility model embodiment provides a curtain fabric composite junction mechanism, such as... Figure 1-2 As shown, the system includes a workbench 1, a take-up roller 2 on one side of the workbench 1, the take-up roller 2 being controlled by a stepper motor on one side, a traction cloth 3 on the take-up roller 2, a traction clamp 4 fixed to one end of the traction cloth 3, side panels 5 on both sides of the workbench 1, and through, horizontal sliding grooves 6 on both side panels 5, with sliders 7 slidably connected in the sliding grooves 6, and fixed clamps 8 on the side of the sliders 7 near the workbench 1, the fixed clamps 8 clamping the two edges of the traction cloth 3, the sliders 7 sliding in the sliding grooves 6 driving the traction cloth 3 to be pulled out, eliminating the need for manual pulling and saving manpower.

[0015] Reference Appendix Figure 2 A connecting beam 9 is provided between the sliders 7, and the connecting beam 9 is located below the worktable 1. A threaded hole is opened at the center of the connecting beam 9. Fixed plates 10 are provided at the front and rear ends of the bottom surface of the worktable 1. A screw 11 is rotatably connected between the fixed plates 10. The screw 11 passes through the threaded hole and is threadedly connected to the connecting beam. A stepper motor 12 is provided on one side of the fixed plate 10, and the output end of the stepper motor 12 is connected to the screw 11. The connecting beam 9 connects the left and right sliders 7, so that the left and right sliders 7 can move synchronously. It should be noted that when the traction cloth 3 is pulled back along with the fabric being processed, the stepper motor controlling the take-up roller retracts the traction cloth 3, and the stepper motor 12 controlling the screw 11 also operates synchronously to pull back the slider 7. The moving speed of the slider 7 is the same as the retraction speed of the traction cloth 3, and the stepper motor 12 controlling the screw 11 starts first when retracting. This ensures that the traction cloth 3 between the fixed clamp 8 and the take-up roller 2 is not in a taut state, avoiding the large difference in the retraction speed of the slider 7 and the traction cloth 3, which could cause misalignment between the fixed clamp 8 and the traction cloth 3.

[0016] Reference Appendix Figure 2 A support frame 17 is provided between the two side panels 5. The lower end of the support frame 17 is provided with a sewing component (not shown in the figure). The upper end of the support frame 17 is provided with a limiting post 13. A pressure roller frame is fitted on the limiting post 13. The pressure roller frame includes a horizontal part 14 and a vertical part 15. One end of the horizontal part 14 is fitted on the limiting post 13, and the bottom surface of the other end is connected to the vertical part 15. The lower end of the vertical part 15 is rotatably connected to a pressure roller. The pressure roller presses the seam of the fabric together, making the sewing effect better.

[0017] Reference Appendix Figure 2 A spring 16 is also fitted onto the limiting post 13. One end of the spring 16 is fixed to the upper surface of the support frame 17, and the other end is fixed to the lower end face of the horizontal part 14. A ring magnet is embedded in the horizontal part 14, surrounding the limiting post 13. An electromagnet 18 is fixed to the upper end face of the limiting post 13. When the traction fabric 3 is pulled out by the slider 6, the electromagnet 18 attracts the pressure roller frame, which, together with the spring 16, causes the pressure roller to rise, and the traction fabric 3 is pulled out smoothly. When the traction clamp 4 pulls the fabric to be processed back, the magnetism of the electromagnet 18 gradually decreases after the traction clamp 4 passes under the pressure roller, and the pressure roller falls and presses on the fabric splice. At the same time, the electromagnet 18 can adjust the pressure of the pressure roller on the fabric splice according to the processing requirements of different fabrics. The limiting post 13 has an elliptical cross-section, which makes the horizontal part 14 stable and prevents it from rotating.

[0018] This utility model discloses a composite hand-sewing mechanism for curtain fabrics. Through the arrangement of a sliding groove, a slider, and a connecting beam, the slider slides within the sliding groove under the drive of a stepper motor. The fixed clamp on the slider holds the edge of the traction fabric, and the slider pulls the traction fabric out, eliminating the need for workers to manually pull out the traction fabric, thus greatly saving manpower. At the same time, the pressure of the pressure roller can also be adjusted by an electromagnet to achieve better sewing results for different fabrics.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
