Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of garment production sewing equipment, specifically a sewing equipment for garment production. Background Technology
[0002] A sewing machine is a machine that uses one or more threads to form one or more layers of fabric, interweaving or sewing together. Sewing machines can sew cotton, linen, silk, wool and other fabrics, as well as leather, plastic, paper and other products. The stitches produced are neat, beautiful, flat and strong. Sewing is fast and easy to use, and has also led to the development of hand embroidery and other techniques.
[0003] Referring to the patent document: Patent Publication No. CN222064886U, Patent Publication Date 2024-11-26, a sewing equipment for producing clothing is disclosed, belonging to the field of sewing device technology. This sewing equipment for producing clothing includes four fixing bolts on the inner wall of a threaded connecting bolt sleeve; each fixing bolt corresponds to a bolt sleeve; an electric cylinder three is fixedly installed inside the sliding block; the output end of the electric cylinder three is fixedly connected to a motor two; the slot is a king-shaped sliding hole; the slot is slidably connected to the output end of the motor two; the bottom support plate is slidably connected to the upper surface of the sliding block; by setting the electric cylinder three to be fixedly connected to the motor two, the output end of the motor two can slide within the slot. With the rotation of the output end of the motor two in conjunction with the adjustment of the electric cylinder three, more complex patterns can be sewn, improving sewing accuracy.
[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:
[0005] Traditional sewing machines for garment sewing have a relatively simple structure when fixing tubular thread assemblies. They often use a limiting rod to directly slip the tubular thread assemblies onto the machine. However, during the sewing process, the sewing machine is frequently started and stopped rapidly, pulling the thread out. This causes the tubular thread assemblies to wobble and rotate due to uneven tension, leading to disordered thread feeding. Once the thread assemblies rotate or shift their position, it can not only cause the thread to become tangled and break, hindering subsequent thread feeding, but also affect the uniformity of the tension when the thread is pulled out due to instability. This negatively impacts the consistency and aesthetics of the sewing stitches, reducing the quality of the garment sewing.
[0006] Therefore, this utility model provides a sewing device for garment production. Utility Model Content
[0007] In order to solve the problem that the existing limiting and fixing structure of the tubular thread group is relatively simple, which makes it unstable during the thread feeding process and prone to tangling and breakage, the purpose of this utility model is to provide a sewing equipment for garment production.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a sewing device for garment production, comprising a sewing machine, wherein the top of the sewing machine is provided with several sets of fixing mechanisms for fixing tubular thread groups, the fixing mechanisms including:
[0009] The limiting assembly includes a bracket set on one side of the top of the sewing equipment. A mounting base is fixedly installed on the lower surface of the bracket. A rotating disk is rotatably installed in the middle of the mounting base. A screw is rotatably installed in the middle of the top of the rotating disk. A movable ring is threaded on the lower part of the screw. Several drive linkages arranged in a ring array are movably installed on one side of the movable ring. Multiple limiting plates arranged in a ring array are provided at the top of the rotating disk. One end of each of the multiple drive linkages is movably installed in the lower part of the limiting plate.
[0010] The rotating assembly, located on the upper part of the bracket, is used to pull the sewing thread.
[0011] Preferably, the rotating assembly includes a rotating pipe rotatably mounted on the upper part of the bracket, a deflection frame fixedly mounted on one side of the lower part of the rotating pipe, a limit ring fixedly mounted on one end of the deflection frame, an inlet on one side of the upper part of the rotating pipe, and an outlet at the top of the rotating pipe.
[0012] Preferably, the upper part of the rotating disk has four evenly distributed limiting grooves, and the lower parts of the four limiting plates are slidably locked inside the limiting grooves.
[0013] Preferably, bolts are threaded onto both sides of the middle portion of the mounting base to limit the rotation of the rotating disk.
[0014] Preferably, an anti-slip collar is fixedly installed on the outer side of the middle part of the rotating disk, and one end of each of the two bolts is in contact with the outer surface of the anti-slip collar.
[0015] Preferably, a rotating handle is fixedly installed at the top of the screw, and multiple evenly distributed mounting holes are provided at the bottom of the bracket for use with fastening bolts to install the bracket at the top of the sewing equipment.
[0016] Beneficial effects
[0017] This utility model provides a sewing device for garment production. Compared with the prior art, it has the following advantages:
[0018] 1. This application uses a rotating handle to drive the screw to rotate, causing the moving ring to move downwards. Under the transmission of the driving link and the limiting groove, multiple limiting plates expand outwards and contact the inner wall of the tubular thread group. Through their tension and friction, they limit and fix the thread, ensuring that during the operation of the sewing equipment and the pulling of the thread, the tubular thread group can avoid disordered thread feeding and tangling due to shaking and rotation, thus ensuring a stable supply of thread.
[0019] 2. This application uses a rope threaded through a limiting ring and extending from the inlet to the outlet. The rope thread is then pulled by the sewing equipment. During use, the deflector rotates synchronously with the rotation of the rope thread as it leaves the winding drum, so that the rope thread is smoothly pulled out of the winding drum. This avoids friction between the pulled-out rope thread and the winding rope thread, reduces the risk of rope thread breakage due to friction, and ensures continuous and stable sewing operations.

[0025] 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.
[0026] Please see Figure 1-4 This utility model provides a technical solution: a sewing device for garment production, including a sewing device 1, the top of which is provided with several sets of fixing mechanisms 2 for fixing tubular thread groups, the fixing mechanisms 2 including:
[0027] The limiting component 21 includes a bracket 211 disposed on one side of the top of the sewing equipment 1. A mounting base 212 is fixedly installed on the lower surface of the bracket 211. A rotating disk 213 is rotatably mounted in the middle of the mounting base 212. A screw 215 is rotatably mounted in the middle of the top of the rotating disk 213. A moving ring 216 is threadedly installed on the lower part of the screw 215. Several driving connecting rods 217 arranged in a ring array are movably mounted on one side of the moving ring 216. Multiple limiting plates 218 arranged in a ring array are provided at the top of the rotating disk 213. One end of each of the multiple driving connecting rods 217 is movably mounted on the lower part of the limiting plate 218.
[0028] The rotating component 22 is located on the upper part of the bracket 211 and is used to pull the sewing thread.
[0029] The rotating assembly 22 includes a rotating pipe 221 rotatably mounted on the upper part of the bracket 211. A deflection frame 222 is fixedly installed on the lower side of the rotating pipe 221. A limit ring 223 is fixedly installed at one end of the deflection frame 222. The position of the limit ring 223 is greater than the outer side of the cylindrical wire group to ensure that it can rotate smoothly with the release of the wire group. At the same time, it avoids the rope from contacting the wound rope and generating friction when it is released. An inlet 224 is opened on the upper side of the rotating pipe 221, and an outlet 225 is opened at the top of the rotating pipe 221. The inlet 224 and the outlet 225 are chamfered to avoid excessive friction with the rope.
[0030] The upper part of the rotating disk 213 has four evenly distributed limiting grooves 219. The lower part of the four limiting plates 218 are slidably locked inside the limiting grooves 219. The cross-section of the limiting grooves 219 is T-shaped, which can ensure the stable limiting of the limiting plates 218, and thus limit and fix the cylindrical wire group through tension and friction.
[0031] Bolts 214 are threaded onto both sides of the middle part of the mounting base 212 to limit the rotation of the rotating disk 213.
[0032] An anti-slip collar 2141 is fixedly installed on the outer side of the middle part of the rotating disk 213. One end of each of the two bolts 214 is in contact with the outer surface of the anti-slip collar 2141, so that the rotating disk 213 is limited by the contact between the bolts 214 and the anti-slip collar 2141, ensuring that it is limited within the supply demand, ensuring the normal release of the rope, and preventing the cylindrical rope group from rotating. When it is away from the anti-slip collar 2141, the rotating disk 213 can rotate with it, so that when the rope is used quickly, the release of the rope cannot keep up and the rope will break.
[0033] A rotating handle 2151 is fixedly installed at the top of the screw 215. The lower part of the bracket 211 has multiple evenly distributed mounting holes 2111 for cooperating with the fastening bolts to install the bracket 211 at the top of the sewing equipment 1. By setting the mounting holes 2111, the bracket 211 can be installed and fixed in cooperation with the fastening bolts, that is, the fixing mechanism 2 can be installed, so that the installation can be carried out according to the number of tubular thread groups used.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] During operation, the cylindrical wire assembly is sleeved on the outside of multiple limiting plates 218. At this time, the screw 215 can be rotated by rotating the rotating rod 2151, causing the moving ring 216 to move downward. Under the transmission of the driving link 217, and with the limiting groove 219 limiting the limiting plates 218, the multiple limiting plates 218 can expand outward. By expanding, they come into contact with the inner wall of the cylindrical wire assembly, and are limited and fixed by their tension and friction, so as to avoid shaking during use.
[0036] In use, the end of the rope can first pass through the limiting ring 223, then through the inlet 224 and out from the outlet 225. It can then be connected to the rope traction device on the sewing equipment 1. When the sewing equipment 1 is started, the rope is pulled, which drives the deflector 222 to rotate synchronously with the rope, so that the rope can be pulled out from the winding drum. This avoids the current method of directly pulling it out vertically, which causes the pulled-out rope to rub against the winding rope, making the rope prone to breakage.

[0038] 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 alterations 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.
