Description

Technical Field

[0001] This utility model relates to the field of sewing thread technology, specifically to an abrasion-resistant polytetrafluoroethylene sewing thread. Background Technology

[0002] Sewing thread is the thread required for knitted garments. Sewing thread can be divided into three main categories according to its raw materials: natural fiber sewing thread, synthetic fiber sewing thread, and blended sewing thread. Among them, polytetrafluoroethylene (PTFE) sewing thread is a sewing thread with special properties, such as excellent temperature resistance, corrosion resistance, low coefficient of friction, and high tensile strength.

[0003] Currently, sewing thread lacks an auxiliary lubrication mechanism. During sewing, high-speed sewing or friction with rough fabrics can generate significant friction, accelerating wear on the thread surface and affecting its quality and lifespan. Therefore, this paper proposes an anti-wear polytetrafluoroethylene (PTFE) sewing thread to incorporate an auxiliary lubrication mechanism. By utilizing auxiliary lubrication and reducing the coefficient of friction, the anti-wear performance of the sewing thread can be improved, thereby enhancing its performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an anti-wear polytetrafluoroethylene sewing thread, which improves the anti-wear performance of the sewing thread by using auxiliary lubrication and reducing the coefficient of friction, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a wear-resistant polytetrafluoroethylene sewing thread, including a shell, a return component and a sewing thread. The return component is provided on the top of the shell, and an oil storage tank is provided inside the shell. A thread roller is rotatably connected to the oil storage tank through a rotating shaft, and the sewing thread is wound on the surface of the thread roller.

[0006] By adopting the above technical solution and using auxiliary lubrication, a lubricating film is formed on the surface of the sewing thread, which can further reduce the coefficient of friction between the thread and objects in contact with the needle, fabric, etc.

[0007] Specifically, the sewing thread includes a core thread, with a winding thread wrapped around the core thread, and an outer thread layer covering the winding thread.

[0008] Specifically, the reflux assembly includes a guide channel, which is connected to an oil storage tank, and pressure rollers are rotatably connected to both sides of the guide channel via a rotating shaft.

[0009] Specifically, the top of the flow channel is connected to a support frame by bolts, and the support frame has a flow port that is connected to the flow channel.

[0010] Specifically, the top of the housing is provided with an oil injection hole on one side of the reflux assembly, and the oil injection hole is connected to the oil storage tank. The outer side of the housing is connected to a mounting plate by bolts, and the surface of the mounting plate is provided with mounting holes.

[0011] The beneficial effects of this utility model are: The wear-resistant polytetrafluoroethylene sewing thread of this utility model, through the addition of a shell, oil reservoir and thread roller, increases the auxiliary lubrication mechanism. By using auxiliary lubrication, a lubricating film is formed on the surface of the sewing thread, which can further reduce the friction coefficient between the thread and objects in contact with the needle, fabric and other objects, reduce wear caused by friction, and thus improve the wear resistance of the sewing thread.

[0012] The wear-resistant polytetrafluoroethylene sewing thread described in this utility model, through the arrangement of the core thread, winding thread and outer thread layer, can increase the spiral structure, which improves the lubrication quality of the sewing thread and also plays an auxiliary role in oil locking. It not only enhances the wear resistance of the sewing thread, but also helps to improve the actual strength of use. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] To improve the wear resistance of sewing thread and thus enhance its performance by utilizing auxiliary lubrication and reducing the coefficient of friction, such as... Figure 1-3As shown, the wear-resistant polytetrafluoroethylene sewing thread of this utility model includes a housing 1, a return assembly 2, and a sewing thread 3. The return assembly 2 is provided on the top of the housing 1. An oil storage tank 101 is provided inside the housing 1. A thread roller 102 is rotatably connected to the oil storage tank 101 through a rotating shaft. The sewing thread 3 is wound around the surface of the thread roller 102.

[0017] In use, the housing 1, oil reservoir 101, thread roller 102 and sewing thread 3 can be used to add an auxiliary lubrication mechanism. By using auxiliary lubrication, a lubricating film is formed on the surface of the sewing thread, reducing the friction coefficient of the sewing thread and thus improving the wear resistance of the sewing thread.

[0018] To improve usability, for example, such as Figure 2 , Figure 4 As shown, the present invention also includes the sewing thread 3 comprising a core thread 301, the core thread 301 being wound with a winding thread 302, and the winding thread 302 being covered with an outer thread layer 303.

[0019] When in use, the core thread 301, the winding thread 302 and the outer thread layer 303 can increase the spiral structure, improve the oil-locking effect of the sewing thread 3, further improve the wear resistance, and also help improve the quality of thread breakage resistance.

[0020] For example, such as Figure 3 As shown, the present invention also includes a flow guide trough 201, which is connected to an oil storage tank 101. Both sides of the flow guide trough 201 are rotatably connected to pressure rollers 202 via rotating shafts.

[0021] During use, the guide groove 201 and pressure roller 202 facilitate the pre-squeezing of the sewing thread 3 surface before use to remove excess lubricating oil, thereby reducing resource waste.

[0022] For example, such as Figure 3 As shown, the present invention also includes a support frame 203 bolted to the top of the guide channel 201, and a guide port 204 is provided in the support frame 203, and the guide port 204 communicates with the guide channel 201.

[0023] During use, the support frame 203 and the guide port 204 facilitate the diversion and recovery of residual lubricating oil at the edge.

[0024] For example, such as Figure 1 As shown, the present invention also includes an oil injection hole 4 on the top of the housing 1 located on one side of the reflux assembly 2, and the oil injection hole 4 is connected to the oil storage tank 101. An installation plate 5 is bolted to the outside of the housing 1, and an installation hole 6 is provided on the surface of the installation plate 5.

[0025] During use, the oil injection hole 4 facilitates the injection of additional lubricating oil into the housing 1, allowing the oil reservoir 101 to continuously lubricate the sewing thread 3. The mounting plate 5 and mounting hole 6 facilitate the pre-fixing of the housing 1.

[0026] In use, this invention first immerses the sewing thread 3 in the lubricating oil in the oil reservoir 101 via the thread roller 102. This auxiliary lubrication method forms a lubricating film on the surface of the sewing thread 3, further reducing the coefficient of friction between it and objects such as needles and fabric. This reduces wear caused by friction and improves the wear resistance of the sewing thread 3. Simultaneously, the spiral structure of the winding yarn 302 and the outer thread layer 303 enhances the oil-locking effect of the sewing thread 3, further improving its wear resistance and reducing its resistance to breakage. Lubricating oil can then be added to the oil reservoir 101 through the oil injection hole 4. The overall structure is simple, compact, low-cost, easy to operate, and provides more stable and reliable use.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
