Description

Technical Field

[0001] This utility model relates to the field of garment production, and in particular to a garment sewing clamp that achieves multi-layer positioning and fixation. Background Technology

[0002] Sewing is a crucial step in garment manufacturing. It refers to the process of connecting the various pieces of a garment (such as the body, sleeves, collar, pockets, etc.) with needles and thread (or other sewing materials) according to design requirements and process standards to form a complete garment structure.

[0003] In the garment production process, sewing multiple layers of fabric is a common procedure, such as sewing the layers of cotton clothing or binding multiple layers of collar. In the traditional sewing process, the positioning and fixing of multiple layers of fabric mainly rely on manual pinching.

[0004] However, when fixing by hand, uneven hand force can easily cause the fabric to slip, especially when sewing thicker or slippery fabrics. It is difficult to keep the layers of fabric aligned, and defects such as crooked lines and misaligned layers are likely to occur after sewing, affecting the quality of the garment. Therefore, a garment sewing clamp that can achieve multi-layer positioning and fixing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a garment sewing clamp for multi-layer positioning and fixing. It aims to improve the problem that uneven hand force during manual fixing in the prior art can easily cause the fabric to slip, especially when sewing thicker or slippery fabrics. It is difficult to keep the layers of fabric aligned, and defects such as crooked lines and misaligned layers are likely to occur after sewing, which affects the quality of the garment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a garment sewing clamp for multi-layer positioning and fixing, comprising a fixing rod, wherein four sets of sliders are provided on the surface of the fixing rod, one set of sliders is fixedly connected to the bottom end of the outer wall of the fixing rod, three sets of sliders are slidably connected to the surface of the fixing rod, a braided rope is provided between the lower three sets of sliders, a pulling rope is provided on the surface of the upper set of sliders, a pressure plate is fixedly connected to the front end surface of the four sets of sliders, an unfolding component is provided on the inner side of the lower three sets of pressure plates, a guide block is fixedly connected to the inner side wall of the four sets of sliders, and the four sets of guide blocks are elastically connected by three sets of return springs.

[0007] As a further description of the above technical solution: The spreading assembly includes a contact block, which is elastically connected to the inner sidewall of the pressure plate by a connecting spring. Both sides of the bottom end of the contact block are hinged with hinge rods, and the ends of the two sets of hinge rods away from the contact block are hinged with spreading support blocks.

[0008] As a further description of the above technical solution: The outer surface of the fixed rod is provided with a groove, and the guide block passes through and is slidably connected to the inner wall of the groove of the fixed rod.

[0009] As a further description of the above technical solution: The contact block is convex in shape and is slidably connected to the inner wall of the top of the pressure plate.

[0010] As a further description of the above technical solution: One end of the connecting spring is fixedly connected to the bottom end of the outer wall of the contact block, and the other end of the connecting spring is fixedly connected to the bottom end of the inner wall of the pressure plate.

[0011] As a further description of the above technical solution: The pressing plate is inverted convex in shape, and sliding grooves are provided on both sides of the bottom end of the pressing plate. The spreading support block is slidably connected to the inner wall of the sliding groove at the bottom end of the pressing plate.

[0012] As a further description of the above technical solution: The bottom end of the outer wall of the clamping plate is in contact with the top end of the outer wall of the contact block.

[0013] As a further description of the above technical solution: Both the bottom ends of the spreading support block and the pressing plate are provided with anti-slip grooves.

[0014] This utility model has the following beneficial effects: 1. In this utility model, through the linkage design of four sets of sliders and pressure plates, the opening and closing of multiple pressure plates can be controlled synchronously by the cooperation of the pull rope and the return spring, ensuring that the multiple layers of fabric are evenly stressed when clamped, and that each layer of fabric is aligned without misalignment. The guide block slides along the groove of the fixed rod, ensuring the stability of the slider movement and avoiding fabric deviation caused by shaking during clamping.

[0015] 2. In this utility model, when the spreading component inside the pressing plate is clamped, the contact block is pressed and drives the hinge rod to push the spreading support block to unfold outward, which can flatten the sewn edges of each layer of fabric outward, avoid wrinkles caused by compression, and improve the flatness of the sewn fabric; the anti-slip groove increases the friction with the fabric, further preventing the fabric from sliding.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3This utility model provides an embodiment of a garment sewing clamp for multi-layer positioning and fixing, comprising a fixing rod 1, with four sets of sliders 2 disposed on the surface of the fixing rod 1. One set of sliders 2 is fixedly connected to the bottom end of the outer wall of the fixing rod 1, and three sets of sliders 2 are slidably connected to the surface of the fixing rod 1. Braided ropes 3 are disposed between the lower three sets of sliders 2, and a pulling rope 4 is disposed on the surface of the upper set of sliders 2. Pulling the pulling rope 4 can move the first set of sliders 2 upwards, and then the remaining three sets of sliders 2 are synchronously pulled upwards by the braided ropes 3, thereby causing the four sets of sliders 2 to open the gap between the pressing plates 5, thus allowing multiple garments to be placed. The front surfaces of the four sets of sliders 2 are all fixedly connected to pressing plates 5, and the lower three sets of pressing plates 5 are slidably connected to the bottom end of the fixing rod 1. The inner side of the tension plate 5 is provided with a spreading component 7. The inner sidewalls of the four sets of sliders 2 are fixedly connected with guide blocks 8. The outer surface of the fixed rod 1 is provided with a groove. The guide blocks 8 pass through and are slidably connected to the inner wall of the groove of the fixed rod 1. By providing guide blocks 8, the up and down movement of the sliders 2 can be guided, so that they can only move up and down on the surface of the fixed rod 1. The four sets of guide blocks 8 are elastically connected by three sets of return springs 6. By providing return springs 6 between the four sets of guide blocks 8, when the pulling rope 4 is pulled, multiple sets of braided ropes 3 will be straightened synchronously. At the same time, when the pulling rope 4 is released, multiple sets of return springs 6 can automatically reset multiple sets of sliders 2, so that multiple sets of pressure plates 5 can come together to press the multi-layer garment.

[0020] Reference Figure 3 and Figure 5 The unfolding assembly 7 includes a contact block 71. The bottom end of the outer wall of the pressing plate 5 contacts the top end of the outer wall of the contact block 71. Through the mutual contact between multiple sets of pressing plates 5, the contact block 71 on the inner side of the lower set of pressing plates 5 can be pushed downward. The contact block 71 is convex in shape and is slidably connected to the inner wall of the top end of the pressing plate 5. The contact block 71 is elastically connected to the inner side wall of the pressing plate 5 by a connecting spring 72. One end of the connecting spring 72 is fixedly connected to the bottom end of the outer wall of the contact block 71, and the other end of the connecting spring 72 is fixedly connected to the bottom end of the inner wall of the pressing plate 5. The function of the connecting spring 72 is to automatically reset the position of the contact block 71 after it moves downward. Both sides of the bottom end of the contact block 71 are hinged with hinge rods 73. The ends of the two sets of hinge rods 73 away from the contact block 71 are hinged with spreading support blocks 74. When the contact block 71 moves downward, it will push the corresponding spreading support blocks 74 outward through the two sets of hinge rods 73, thereby pushing the two sides of the garment to be sewn outward to prevent wrinkles at the sewing point. The pressing plate 5 is convex in shape. Both sides of the bottom end of the pressing plate 5 are provided with sliding grooves. The spreading support blocks 74 are slidably connected to the inner wall of the sliding grooves at the bottom end of the pressing plate 5. The bottom ends of the spreading support blocks 74 and the pressing plate 5 are provided with anti-slip grooves. By providing anti-slip grooves, the friction between the spreading support blocks 74 and the garment can be increased.

[0021] Working principle: In the initial state, the four sets of sliders 2 are brought closer together by the action of the three sets of return springs 6, which also causes the four sets of pressing plates 5 to be in a state of mutual contact. Among them, one set of sliders 2 is fixedly connected to the bottom end of the outer wall of the fixed rod 1, and the other three sets of sliders 2 are slidably connected to the surface of the fixed rod 1. The guide blocks 8 on the inner side of the four sets of sliders 2 pass through and are slidably connected in the groove of the fixed rod 1, providing guidance for the up and down movement of the sliders 2, ensuring that they can only move up and down on the surface of the fixed rod 1.

[0022] When multiple layers of clothing need to be placed, pull the pull rope 4 on the surface of the upper slider 2. The pull rope 4 will drive the first slider 2 to move upward. Since there are braided ropes 3 between the three lower sliders 2, the upward movement of the first slider 2 will simultaneously pull the remaining three sliders 2 upward through the braided ropes 3, so that the gap between the four sliders 2 opens up, and in turn, the gap between the four pressure plates 5 also opens up. At this time, multiple garments to be sewn can be placed between adjacent pressure plates 5.

[0023] After the pull rope 4 is released, the three sets of reset springs 6 between the four sets of guide blocks 8 will generate elastic force, which will drive the multiple sets of sliders 2 to automatically reset, so that the four sets of sliders 2 move closer to each other, and then the four sets of pressing plates 5 also move closer to each other, pressing and fixing the multi-layer garments placed between them.

[0024] During the process of the pressing plates 5 being pressed together, the spreading components 7 on the inner sides of the three sets of pressing plates 5 below will function. When the upper pressing plate 5 contacts the lower pressing plate 5, it will push the contact block 71 on the inner side of the lower pressing plate 5 downward. The contact block 71 is slidably connected to the inner wall at the top of the pressing plate 5. Its downward movement will compress the connecting spring 72. At the same time, the two sets of hinge rods 73 hinged on both sides of the bottom end of the contact block 71 will move accordingly, pushing the two sets of spreading support blocks 74 to move outward along the sliding groove at the bottom end of the pressing plate 5, spreading the support blocks. When block 74 moves outward, it can push the two sides of the corresponding layer of clothing to be sewn outward to prevent wrinkles from forming at the sewing point. In addition, the bottom ends of both the spreading support block 74 and the pressing plate 5 are provided with anti-slip grooves, which can increase the friction between the garment and the clothing, further ensuring the stability of the garment during the sewing process. When the garment needs to be removed, pull the pulling rope 4 again to open the gap between the pressing plates 5. The contact block 71 is reset under the action of the connecting spring 72, which drives the hinge rod 73 and the spreading support block 74 back to their original positions, making it convenient to remove the garment.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
