Description

Technical Field

[0001] The present invention relates to the technical field of sewing thread stretching equipment, in particular to a polytetrafluoroethylene sewing thread stretching equipment and a use method thereof. Background Art

[0002] Polytetrafluoroethylene sewing thread, also known as PTFE sewing thread, is made of polytetrafluoroethylene material. It has good non-stickiness and heat resistance, is suitable for high temperature environments, has excellent chemical stability, and has properties such as wear resistance, corrosion resistance and high tensile strength. Sewing thread stretching equipment is mainly used in the production of polytetrafluoroethylene fibers and wires to improve the strength, rigidity and dimensional stability of the material through the stretching process. The function of these equipment is to heat and soften the polytetrafluoroethylene raw material, and then stretch the fiber to achieve the required physical properties.

[0003] Among them, when stretching the polytetrafluoroethylene sewing thread, in order to reduce the friction between the sewing thread and the stretching roller, it is often necessary to apply lubricant to the sewing thread. The common application method is to apply lubricant to the entire coating roller and then apply it to the surface of the sewing thread through the coating roller. When the lubricant is applied to the entire coating roller surface, it may cause the lubricant dosage on the coating roller to be difficult to be evenly distributed, which may cause excessive or insufficient lubricant in some areas, affecting the application effect. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a polytetrafluoroethylene sewing thread stretching device, comprising a conveyor frame, a motor fixedly connected to the side wall of the conveyor frame, five pulleys rotatably connected to the side wall of the conveyor frame, a belt 1 being sleeved on the outer wall of the five pulleys 1, six outer pressure wheels rotatably connected to the side wall of the conveyor frame, the side wall of the pulley 1 on the left side being fixedly connected to the output end of the motor on the side wall, and a diffusion component being provided on the side wall of the conveyor frame; The stretching mechanism includes thirteen sewing threads, a stretching roller and a pressure wheel assembly for stretching the sewing threads, and a coating assembly for coating the surface of the sewing threads with lubricant; There are five stretching rollers, and the outer walls of the five stretching rollers are rotatably connected to the inner wall of the conveying frame. The side walls of the five stretching rollers are fixedly connected to the side walls of the five pulleys. The outer walls of the thirteen sewing threads are rotatably connected to the outer walls of the five stretching rollers. The outer wall of the pressure wheel group is rotatably connected to the inner wall of the conveying frame. The liquid medium in the lubricant, such as silicone oil, synthetic oil, etc., is added to the liquid storage frame through the infusion tube, and then the sewing thread passes through the top of the stretching roller at the top and the bottom of the stretching roller at the bottom, such as Figure 2As shown, the motor is then started to drive the pulley 1 on the left to rotate clockwise, and the belt 1 drives multiple pulleys 1 to rotate simultaneously, so that multiple stretching rollers rotate simultaneously to stretch the sewing thread. At the same time, when the stretching roller on the left rotates, it will also drive the pulley 2 to rotate, so that the belt 2 rotates, and the pulley 3 rotates, so that the pressure wheel group rotates to squeeze the sewing thread. When the pressure wheel group rotates, it will also drive the rotating block to rotate. When the rotating block contacts the U-shaped rod during the rotation process, it will push the U-shaped rod up, thereby raising the blocking plate and driving the blocking ring to rise. When the U-shaped rod rises, it will also contact the seesaw, pushing the seesaw to rotate, so that the side of the seesaw in contact with the U-shaped rod rises and the other side lowers. The lowered side will squeeze the spring pressure plate down, allowing the spring pressure plate to accumulate rebound force. When the spring pressure plate covers the air hole 1, the spring pressure plate will squeeze the gas in the liquid storage frame. At this time, the squeezed gas will be blocked by the spring blocking block, so the gas pressure will increase. As the U-shaped rod continues to move, the blocking ring will separate from the liquid outlet pipe, allowing the lubricant The lubricant in the liquid storage frame can be discharged through the liquid outlet pipe. At the same time, the spring pressure plate will also drive the convex rod to contact the spring blocking block, allowing the spring blocking block to rotate and accumulate rebound force. When the spring blocking block rotates, a gap will leak out between it and the air pipe. The high-pressure gas will push the lubricant in the liquid storage frame through the gap and flow out from the liquid outlet pipe to the surface of the pressure wheel group. The pressure wheel group rotates to make the lubricant adhere to the surface of the sewing thread. When the rotating block separates from the U-shaped rod during the rotation process, the rebound force of the spring pressure plate will be released, allowing the spring pressure plate to return to its position, driving the U-shaped rod and the blocking plate The blocking ring returns to its original position, allowing the blocking ring to block the liquid outlet pipe again until the rotating block contacts the U-shaped rod again, and this reciprocating process can control the dosage of the lubricant applied to the surface of the pressure roller group, so that the lubricant on the surface of the pressure roller group is evenly distributed. In this way, when the pressure roller group rotates and contacts the sewing thread, the surface of the sewing thread obtains a uniform lubrication effect, effectively preventing local uneven lubrication caused by too much or too little lubricant; in addition: by accelerating the flow rate of the lubricant, it is effectively prevented that the lubricant has a high viscosity and is difficult to flow to the surface of the pressure roller group in time.

When the spring pressure plate descends, it will also drive the connecting rod to descend, and the connecting rod will drive the connecting rod to descend, allowing the connecting rod to rotate, pushing the sliding frame away from the liquid storage frame, and driving the push plate to move. When the push plate moves over the air hole 2, the right side of the push plate is in a sealed state at this time, and the push plate will squeeze the gas in the air collecting frame to generate high pressure in the gas. As the push plate continues to move, the push rod driven by the push plate will contact the spring baffle, thereby pushing the spring baffle to move.

[0010] Preferably, the cleaning assembly includes an arc-shaped scraper slidably connected to the inner wall of the conveying frame, an L-shaped rod is fixedly connected to the outer wall of the arc-shaped scraper, a return spring is fixedly connected to the side wall of the arc-shaped scraper, a fixing frame is fixedly connected to the side wall of the liquid storage frame, and the outer wall of the arc-shaped scraper is slidably connected to the inner wall of the fixing frame; Wherein, a concave-convex plate is slidably connected to the side wall of the conveying frame, and the side wall of the concave-convex plate is fixedly connected to the side wall of the sliding frame.

When the sliding frame moves away from the liquid storage frame, it will also drive the concave-convex plate to move. When the convex position of the concave-convex plate contacts the L-shaped rod, it will push the L-shaped rod toward the fixed frame, driving the arc scraper to move, allowing the arc scraper to squeeze the reset spring, so that the reset spring accumulates rebound force. When the convex position of the concave-convex plate is separated from the L-shaped rod, the rebound force of the reset spring will be released, allowing the arc scraper to return to its position, and so on and so forth, the arc scraper will scrape the surface of the pressure wheel group and clean its surface.

When the arc scraper moves toward the fixed frame, it will drive the collection frame and the fixed frame to move together. At this time, the pushing rod contacts the slope of the sloped block, causing the pushing rod to be squeezed away from the collection frame, thereby driving the spring sliding plate to move, so that the right side of the spring sliding plate generates suction, attracting impurities on the arc scraper, causing the impurities to fall into the collection frame and be concentrated through the slope of the collection frame.

[0013] A method for using a polytetrafluoroethylene sewing thread stretching device comprises the following steps: S1: Threading and stretching: pass the sewing thread through the top of the stretching roller at the top and through the bottom of the stretching roller at the bottom; S2: Start the device: Start the motor to drive the pulley on the left to rotate clockwise, and the belt drives multiple pulleys to rotate simultaneously, so that multiple stretching rollers rotate simultaneously to stretch the sewing thread.

[0014] The present invention has the following beneficial effects: (1) When the present invention is used, a liquid medium such as silicone oil, synthetic oil, etc. in the lubricant is added to the liquid storage frame through the infusion tube, and then the sewing thread passes through the top of the stretching roller at the top and the bottom of the stretching roller at the bottom, such as Figure 2As shown, the motor is then started to drive the pulley 1 on the left to rotate clockwise, and the belt 1 drives multiple pulleys 1 to rotate simultaneously, so that multiple stretching rollers rotate simultaneously to stretch the sewing thread. At the same time, when the stretching roller on the left rotates, it will also drive the pulley 2 to rotate, so that the belt 2 rotates, and the pulley 3 rotates, so that the pressure wheel group rotates to squeeze the sewing thread. When the pressure wheel group rotates, it will also drive the rotating block to rotate. When the rotating block contacts the U-shaped rod during the rotation process, it will push the U-shaped rod up, thereby raising the blocking plate and driving the blocking ring to rise. When the U-shaped rod rises, it will also contact the seesaw, pushing the seesaw to rotate, so that the side of the seesaw in contact with the U-shaped rod rises and the other side lowers. The lowered side will squeeze the spring pressure plate down, allowing the spring pressure plate to accumulate rebound force. When the spring pressure plate covers the air hole 1, the spring pressure plate will squeeze the gas in the liquid storage frame. At this time, the squeezed gas will be blocked by the spring blocking block, so the gas pressure will increase. As the U-shaped rod continues to move, the blocking ring will separate from the liquid outlet pipe, allowing the lubricant The lubricant in the liquid storage frame can be discharged through the liquid outlet pipe. At the same time, the spring pressure plate will also drive the convex rod to contact the spring blocking block, allowing the spring blocking block to rotate and accumulate rebound force. When the spring blocking block rotates, a gap will leak out between it and the air pipe. The high-pressure gas will push the lubricant in the liquid storage frame through the gap and flow out from the liquid outlet pipe to the surface of the pressure wheel group. The pressure wheel group rotates to make the lubricant adhere to the surface of the sewing thread. When the rotating block separates from the U-shaped rod during the rotation process, the rebound force of the spring pressure plate will be released, allowing the spring pressure plate to return to its position, driving the U-shaped rod and the blocking plate The blocking ring returns to its original position, allowing the blocking ring to block the liquid outlet pipe again until the rotating block contacts the U-shaped rod again, and this reciprocating process can control the dosage of the lubricant applied to the surface of the pressure roller group, so that the lubricant on the surface of the pressure roller group is evenly distributed. In this way, when the pressure roller group rotates and contacts the sewing thread, the surface of the sewing thread obtains a uniform lubrication effect, effectively preventing local uneven lubrication caused by too much or too little lubricant; in addition: by accelerating the flow rate of the lubricant, it is effectively prevented that the lubricant has a high viscosity and is difficult to flow to the surface of the pressure roller group in time.

[0015] (2) In the present invention, when the spring pressure plate descends, it also drives the connecting rod to descend, and the connecting rod drives the connecting rod to descend, causing the connecting rod to rotate, pushing the sliding frame away from the liquid storage frame, and driving the push plate to move. When the push plate moves over the second air hole, the right side of the push plate is in a sealed state, and the push plate will squeeze the gas in the gas collection frame, causing the gas to generate high pressure. As the push plate continues to move, the push rod driven by the push plate will contact the spring baffle, thereby driving the spring baffle to move, allowing the spring baffle to accumulate rebound force. When the spring baffle moves, it will separate from the air jet tube. At this time, the high-pressure gas will enter the air jet tube and spray toward the surface of the sewing thread, accelerating the penetration speed of the lubricant on the surface of the sewing thread, and effectively preventing the lubricant from not completely penetrating into the sewing thread during the stretching process, which may cause it to fall off.

[0016] (3) When the sliding frame of the present invention is away from the liquid storage frame, it will also drive the concave-convex plate to move. When the convex position of the concave-convex plate contacts the L-shaped rod, it will push the L-shaped rod to move toward the fixed frame, driving the arc scraper to move, allowing the arc scraper to squeeze the reset spring, so that the reset spring accumulates rebound force. When the convex position of the concave-convex plate is separated from the L-shaped rod, the rebound force of the reset spring will be released, allowing the arc scraper to return to its position. In this way, the arc scraper will scrape the surface of the pressure wheel group and clean its surface. At the same time, when the concave-convex plate moves, it will also drive the extrusion plate to move, squeezing the gas in the connecting block, so that the gas is sprayed toward the cleaned surface of the pressure wheel group, accelerating its drying speed. By cleaning the surface of the pressure wheel group, it is effectively prevented that when the pressure wheel group contacts the sewing thread, impurities on the surface of the sewing thread follow the lubricant remaining on the surface of the pressure wheel group and adhere to the surface of the pressure wheel group, affecting the uniform distribution of the lubricant on the surface of the pressure wheel group.

[0017] (4) When the arc scraper moves toward the fixed frame, the present invention will drive the collection frame and the fixed frame to move together. At this time, the push rod contacts the inclined surface of the inclined block, causing the push rod to be squeezed and away from the collection frame, thereby driving the spring sliding plate to move, so that the right side of the spring sliding plate generates suction, attracting impurities on the arc scraper, causing the impurities to fall into the collection frame and be concentrated through the inclined surface of the collection frame. When the impurities accumulate to a certain extent, the arc scraper returns to its position, driving the impurities in the collection frame to contact the fixed rod, so that the impurities are squeezed by the fixed rod, and the fixed rod will push them toward the fixed frame, and a small amount of impurities will be discharged through the sewage pipe until the discharged impurities accumulate again. By collecting and discharging the impurities, it is effectively prevented that a large amount of impurities accumulate on the arc scraper, and the impurities may fall onto the surface of the sewing thread, affecting the cleaning effect.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] For example 1, please refer to Figure 1 - Figure 7The present invention is a polytetrafluoroethylene sewing thread stretching device, comprising a conveyor frame 1, a motor 11 is fixedly connected to the side wall of the conveyor frame 1, five pulleys 12 are rotatably connected to the side wall of the conveyor frame 1, a belt 13 is sleeved on the outer wall of the five pulleys 12, six outer pressure wheels 14 are rotatably connected to the side wall of the conveyor frame 1, the side wall of the left pulley 12 is fixedly connected to the output end of the motor 11, and a diffusion component 4 is provided on the side wall of the conveyor frame 1; The stretching mechanism 2 includes thirteen sewing threads 22, a stretching roller 21 for stretching the sewing threads 22, a pressing wheel assembly 23, and a coating assembly 3 for coating the surface of the sewing threads 22 with lubricant; There are five stretching rollers 21, and the outer walls of the five stretching rollers 21 are rotatably connected to the inner wall of the conveying frame 1. The side walls of the five stretching rollers 21 are fixedly connected to the side walls of the five pulleys 12. The outer walls of the thirteen sewing threads 22 are rotatably connected to the outer walls of the five stretching rollers 21, and the outer wall of the pressure wheel group 23 is rotatably connected to the inner wall of the conveying frame 1. The liquid medium in the lubricant, such as silicone oil, synthetic oil, etc., is added to the liquid storage frame 31 through the infusion tube 312, and then the sewing thread 22 passes through the top of the stretching roller 21 at the top and the bottom of the stretching roller 21 at the bottom, as shown in FIG. Figure 2As shown, the motor 11 is then started to drive the pulley 12 on the left to rotate clockwise, and the belt 1 13 drives multiple pulleys 12 to rotate simultaneously, so that multiple stretching rollers 21 rotate simultaneously to stretch the sewing thread 22. At the same time, when the stretching roller 21 on the left rotates, it also drives the pulley 2 33 to rotate, so that the belt 2 331 rotates, and drives the pulley 3 332 to rotate, so that the pressure wheel group 23 rotates to squeeze the sewing thread 22. When the pressure wheel group 23 rotates, it also drives the rotating block 34 to rotate. When the rotating block 34 contacts the U-shaped rod 35 during the rotation process, the U-shaped rod 35 will be lifted up, so that the sewing thread 22 can be stretched. The blocking plate 36 rises, driving the blocking ring 362 to rise. When the U-shaped rod 35 rises, it will also contact the seesaw 37, pushing the seesaw 37 to rotate, so that the side of the seesaw 37 in contact with the U-shaped rod 35 rises and the other side falls. The lowered side will squeeze the spring pressure plate 32 down, allowing the spring pressure plate 32 to accumulate resilience. When the spring pressure plate 32 covers the air hole 1 311, the spring pressure plate 32 will squeeze the gas in the liquid storage frame 31. At this time, the squeezed gas will be blocked by the spring blocking block 381, so the gas pressure will increase.

At the same time, the spring pressure plate 32 will also drive the protruding rod 321 to contact the spring blocking block 381, so that the spring blocking block 381 rotates and accumulates the rebound force. The rotation of the spring blocking block 381 will leak a gap between it and the gas pipe 38. The high-pressure gas will push the lubricant in the liquid storage frame 31 through the gap and flow out from the liquid outlet pipe 361 to the surface of the pressure wheel group 23. The pressure wheel group 23 rotates to make the lubricant adhere to the surface of the sewing thread 22. When the rotating block 34 rotates and separates from the U-shaped rod 35, the rebound force of the spring pressure plate 32 will be released, allowing the spring pressure plate 32 to return to its original position, driving the U The U-shaped rod 35, the blocking plate 36 and the blocking ring 362 return to their original positions, allowing the blocking ring 362 to block the liquid outlet pipe 361 again until the rotating block 34 contacts the U-shaped rod 35 again, and so on. The dosage of the lubricant applied to the surface of the pressure wheel group 23 can be controlled, so that the lubricant on the surface of the pressure wheel group 23 is evenly distributed. In this way, when the pressure wheel group 23 rotates and contacts the sewing thread 22, the surface of the sewing thread 22 obtains a uniform lubrication effect, effectively preventing local uneven lubrication caused by too much or too little lubricant; in addition: by accelerating the flow rate of the lubricant, it is effectively prevented that the lubricant has a high viscosity and is difficult to flow to the surface of the pressure wheel group 23 in time.

When the convex position of the concave-convex plate 53 contacts the L-shaped rod 511, it will push the L-shaped rod 511 to move toward the fixed frame 52, driving the arc scraper 51 to move, allowing the arc scraper 51 to squeeze the return spring 512, so that the return spring 512 accumulates rebound force. When the convex position of the concave-convex plate 53 is separated from the L-shaped rod 511, the rebound force of the return spring 512 will be released, allowing the arc scraper 51 to return to its position, and so on. The arc scraper 51 will scrape the surface of the pressure wheel group 23 and clean its surface.

[0030] The cleaning assembly 5 also includes a pushing rod 562 fixedly connected to the side wall of the spring sliding plate 561, a sloped block 563 fixedly connected to the side wall of the conveying frame 1, and a fixed rod 57 slidably connected to the inner wall of the collecting frame 55. The side wall of the fixed rod 57 is fixedly connected to the side wall of the conveying frame 1, and a sewage pipe 58 is connected through the side wall of the collecting frame 55. When the arc scraper 51 moves toward the fixed frame 52, it will drive the collecting frame 55 and the fixed frame 56 to move together. At this time, the pushing rod 562 contacts the slope of the sloped block 563, causing the pushing rod 562 to be squeezed away from the collecting frame 55, thereby driving the spring sliding plate 561 to move, so that the right side of the spring sliding plate 561 generates suction, attracting impurities on the arc scraper 51, causing the impurities to fall into the collecting frame 55 and be concentrated through the slope of the collecting frame 55.

[0031] There is no limit to the number of the above components, and relevant technicians in this field can freely set them according to actual needs. It is only necessary to ensure that the above components are installed at the connection positions of the corresponding components.

[0032] The method for using the polytetrafluoroethylene sewing thread stretching device includes the following steps: S1: threading and stretching: passing the sewing thread 22 from the top of the stretching roller 21 at the top and from the bottom of the stretching roller 21 at the bottom; S2: Start the device: Start the motor 11 to drive the pulley 12 on the left to rotate clockwise, and drive multiple pulleys 12 to rotate simultaneously through the belt 13, so that multiple stretching rollers 21 rotate simultaneously to stretch the sewing thread 22.

[0033] A specific application of this embodiment is: when the present invention is used, the liquid medium in the lubricant, such as silicone oil, synthetic oil, etc., is added to the liquid storage frame 31 through the infusion tube 312, and then the sewing thread 22 passes through the top of the stretching roller 21 at the top and the bottom of the stretching roller 21 at the bottom, such as Figure 2As shown, the motor 11 is then started to drive the pulley 12 on the left to rotate clockwise, and the belt 1 13 drives multiple pulleys 12 to rotate simultaneously, so that multiple stretching rollers 21 rotate simultaneously to stretch the sewing thread 22. At the same time, when the stretching roller 21 on the left rotates, it also drives the pulley 2 33 to rotate, so that the belt 2 331 rotates, and drives the pulley 3 332 to rotate, so that the pressure wheel group 23 rotates to squeeze the sewing thread 22. When the pressure wheel group 23 rotates, it also drives the rotating block 34 to rotate. When the rotating block 34 contacts the U-shaped rod 35 during the rotation process, the U-shaped rod 35 will be lifted up, so that the sewing thread 22 can be stretched. The blocking plate 36 rises, driving the blocking ring 362 to rise. When the U-shaped rod 35 rises, it will also contact the seesaw 37, pushing the seesaw 37 to rotate, so that the side of the seesaw 37 in contact with the U-shaped rod 35 rises and the other side falls. The lowered side will squeeze the spring pressure plate 32 down, allowing the spring pressure plate 32 to accumulate resilience. When the spring pressure plate 32 covers the air hole 1 311, the spring pressure plate 32 will squeeze the gas in the liquid storage frame 31. At this time, the squeezed gas will be blocked by the spring blocking block 381, so the gas pressure will increase. As the U-shaped rod 35 continues to move, the blocking ring 362 will separate from the liquid outlet pipe 361. The lubricant can be discharged through the liquid outlet pipe 361. At the same time, the spring pressure plate 32 will also drive the protruding rod 321 to contact the spring blocking block 381, so that the spring blocking block 381 rotates and accumulates the rebound force. The rotation of the spring blocking block 381 will leak a gap between it and the gas pipe 38. The high-pressure gas will push the lubricant in the liquid storage frame 31 through the gap and flow out from the liquid outlet pipe 361 to the surface of the pressure wheel group 23. The pressure wheel group 23 rotates to make the lubricant adhere to the surface of the sewing thread 22. When the rotating block 34 rotates and separates from the U-shaped rod 35, the rebound force of the spring pressure plate 32 will be released, allowing the spring pressure plate 32 to return to its original position, driving the U The U-shaped rod 35, the blocking plate 36 and the blocking ring 362 return to their original positions, allowing the blocking ring 362 to block the liquid outlet pipe 361 again until the rotating block 34 contacts the U-shaped rod 35 again, and this reciprocating process can control the amount of lubricant applied to the surface of the pressing wheel group 23, so that the lubricant on the surface of the pressing wheel group 23 is evenly distributed. In this way, when the pressing wheel group 23 rotates and contacts the sewing thread 22, the surface of the sewing thread 22 obtains a uniform lubrication effect, effectively preventing local uneven lubrication caused by excessive or insufficient lubricant; in addition, by accelerating the flow rate of the lubricant, it is effectively prevented that the lubricant has a high viscosity and is difficult to flow to the surface of the pressing wheel group 23 in time; When the spring pressure plate 32 returns to its original position, the air hole 311 will be connected to the inside of the liquid storage frame 31 again, and the external air will flow into the liquid storage frame 31 through the air hole 311, completing the gas replenishment. When the spring pressure plate 32 moves down, it also drives the connecting rod 43 to move down, and the connecting rod 43 drives the connecting rod 431 to move down, so that the connecting rod 431 rotates, pushing the sliding frame 421 away from the liquid storage frame 31, and driving the pushing plate 42 to move. When the pushing plate 42 moves over the air hole 411, the right side of the pushing plate 42 is in a sealed state at this time, and the pushing plate 42 squeezes the gas in the gas collecting frame 41, so that the gas generates high pressure. As the pushing plate 42 continues to move, the push rod 45 driven by the pushing plate 42 comes into contact with the spring baffle 44, thereby pushing the spring baffle 44 to move, allowing the spring baffle 44 to accumulate rebound force, and the spring baffle 44 moves to separate from the air jet 46. At this time, the high-pressure gas enters the air jet 46 and sprays toward the surface of the sewing thread 22, accelerating the penetration speed of the lubricant on the surface of the sewing thread 22, and effectively preventing the lubricant from not completely penetrating into the sewing thread 22 during the stretching process, which may cause it to fall off; When the pressure wheel assembly 23 returns to its original position, the push plate 42 also returns to its original position, allowing the second air hole 411 to communicate with the right side of the push plate 42, so that the external air enters the air collecting frame 41 through the second air hole 411; Secondly, when the sliding frame 421 is away from the liquid storage frame 31, it will also drive the concave-convex plate 53 to move. When the convex position of the concave-convex plate 53 contacts the L-shaped rod 511, it will push the L-shaped rod 511 to move toward the fixed frame 52, driving the curved scraper 51 to move, so that the curved scraper 51 squeezes the return spring 512, so that the return spring 512 accumulates resilience. When the convex position of the concave-convex plate 53 is separated from the L-shaped rod 511, the resilience of the return spring 512 will be released, allowing the curved scraper 51 to return to its original position. This reciprocating process will cause the curved scraper 51 to return to its original position. The surface of the pressing wheel group 23 will be scraped to clean it. At the same time, when the concave-convex plate 53 moves, it will also drive the extrusion plate 541 to move, squeezing the gas in the connecting block 54 so that the gas is sprayed toward the cleaned surface of the pressing wheel group 23 to accelerate its drying speed. By cleaning the surface of the pressing wheel group 23, it is effectively prevented that when the pressing wheel group 23 contacts the sewing thread 22, impurities on the surface of the sewing thread 22 are attached to the surface of the pressing wheel group 23 along with the lubricant remaining on the surface of the pressing wheel group 23, thereby affecting the uniform distribution of the lubricant on the surface of the pressing wheel group 23. Secondly, when the arc scraper 51 moves toward the fixed frame 52, it will drive the collection frame 55 and the fixed frame 56 to move together. At this time, the pushing rod 562 contacts the inclined surface of the inclined block 563, causing the pushing rod 562 to be squeezed and away from the collection frame 55, thereby driving the spring sliding plate 561 to move, so that the right side of the spring sliding plate 561 generates suction, attracting impurities on the arc scraper 51, causing the impurities to fall into the collection frame 55 and be concentrated through the inclined surface of the collection frame 55. When the impurities accumulate to a certain extent, the arc scraper 51 returns to its original position, driving the impurities in the collection frame 55 to contact the fixed rod 57, so that the impurities are squeezed by the fixed rod 57, and the fixed rod 57 will push them to move toward the fixed frame 52, and discharge a small amount of impurities through the drain pipe 58 until the discharged impurities accumulate again. By collecting and discharging impurities, it is effectively prevented that a large amount of impurities accumulate on the arc scraper 51, and the impurities may fall onto the surface of the sewing thread 22, affecting the cleaning effect.
