Description

Technical Field

[0001] The utility model discloses a cloth folding, sewing and pressing mechanism, belonging to the technical field of cloth processing. Background Art

[0002] Cloth is a commonly used material in decoration, and there are many types of materials. During the production and processing of the cloth, it is necessary to cut the cloth according to its purpose. After cutting, the rough edges generated during the cutting of the cloth need to be locked and sewn. When sewing, the rough edges need to be rolled and folded inwards and sewn by using a sewing device. When the cloth needs to be folded in half and sewn, the cloth needs to be folded in half into a flat state in advance. This operation often relies on manual operation. This method cannot ensure the flatness of the cloth after being folded in half, resulting in easy misalignment of the sewing position, and the sewing line is easy to become a diagonal line. At the same time, continuous sewing cannot be performed, which undoubtedly increases the requirements for workers' operating skills. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 5 As shown, a cloth folding and sewing cloth pressing mechanism comprises a workbench 1, a folding plate 3 is arranged on one side of the workbench 1, a pre-tightening member 2 is arranged at one end of the folding plate 3, the pre-tightening member 2 comprises a limit block 12, a limit bolt 11 and a first spring 14, two of the first spring 14 and the limit bolt 11 are arranged, one end of the limit bolt 11 passes through the limit block 12 and the folding plate 3 and is threadedly connected to the workbench 1, the first spring 14 is sleeved on the limit bolt 11, and the two ends of the first spring 14 respectively contact the limit block 12 and the folding plate 3, two groups of cloth pressing members are arranged on the workbench 1, a certain distance is therebetween, and the cloth pressing members comprise cloth pressing rollers 5 and mounting members 4, the cloth is folded along the folding plate 3, and the sewing position after the folding is arranged toward the sewing device, and the two groups of cloth pressing members can flatten the folded cloth so that the sewing position of the cloth remains flat.

[0020] The folding plate 3 includes a fixed plate 10 and a telescopic plate 9. One end of the fixed plate 10 is connected to the limit bolt 11, and the other end is provided with a notch groove 18. The telescopic plate 9 has an engaging block 20 that cooperates with the groove, and the telescopic plate 9 is provided with two parallel distributed pins 19. The fixed plate 10 is provided with a waist-shaped groove 17 that cooperates with the pin 19. By pulling one end of the telescopic plate 9, the telescopic plate 9 moves relative to the fixed plate 10, and the pin 19 slides in the waist-shaped groove 17. In this way, the overall length of the fixed plate 10 and the telescopic plate 9 becomes larger, so that it can adapt to the folding and sewing processing of fabrics of different widths.

[0021] The fixed plate 10 is provided with a fastener for applying a pre-tightening force to the engaging block 20, and the fastener includes a push rod 15 and a second spring 16. The push rod 15 is in a stepped structure, and its end with a small diameter passes through the fixed plate 10. The second spring 16 is sleeved on the push rod 15 and applies a force to the push rod 15 to resist the engaging block 20. The force of the second spring 16 on the push rod 15 is transmitted to the telescopic plate 9, so that the telescopic plate 9 and the fixed plate 10 have a certain fastening effect, and the overall length of the two will not change due to the transportation of the cloth.

[0022] Two pulling parts 13 are provided at one end of the fixing plate 10 close to the limiting bolt 11, and the pulling part 13 is an inverted L-shaped structure. By providing the pulling part 13, when the cloth needs to be folded in half, the pulling part 13 is lifted upward to make the folding plate 3 move upward and can press a part of the cloth. Then, the pulling part 13 is released and the other part of the cloth can be covered on the folding plate 3, thereby completing the folding of the cloth. The operation is simple and convenient.

[0023] The mounting member 4 comprises a fixed block 21, a third spring 23 and a movable block 24. The fixed block 21 is fixed to the workbench 1 by bolts, and a slide groove 25 is arranged in the middle of the fixed block 21. The movable block 24 is fixed to the end of the cloth pressing roller 5 and is slidably arranged in the slide groove 25. A guide rod 22 is arranged on the movable block 24, and one end of the guide rod 22 penetrates the fixed block 21. The third spring 23 is sleeved on the guide rod 22 and applies a downward force to the movable block 24. The cloth pressing roller 5 keeps pressing the folded cloth under the elastic force of the third spring 23, so that the folded cloth can be kept flat and the sewing device can sew it smoothly.

[0024] The conveying device also includes a conveying device for pulling the cloth, the conveying device includes a mounting frame 7 and two groups of conveyor belts 6 distributed up and down, the mounting frame 7 is fixed to the side of the workbench 1, the conveyor belt 6 is arranged on the mounting frame 7, and the conveyor belt 6 is provided with needle bars 8 distributed at equal intervals. When the two conveyor belts 6 are in a circular rotation, the needle bars 8 can be driven to rotate synchronously. The needle bars 8 will be inserted into the cloth when they are close to the cloth, and the cloth is driven to move to one side by the needle bars 8. In this way, the sewing device can be used to continuously sew the folded cloth, which can effectively improve the efficiency of the folding sewing. A winding device is added on one side of the conveying device, and the winding device winds up the cloth to allow the folded cloth to separate from the needle bars 8.
