Description

Technical Field

[0001] This invention relates to the textile field, specifically to a processing equipment and method for cotton-type filament sewing thread. Background Technology

[0002] Sewing thread is the thread used in knitted garments. Sewing thread can be categorized into three main types based on its raw materials: natural fiber sewing thread, synthetic fiber sewing thread, and blended sewing thread. With the development of the polyester industry, pure polyester fiber is increasingly being used as the raw material for sewing thread. Chinese invention patent CN115161838A discloses a processing method for cotton-type filament sewing thread. This method involves using an integrated napping and temperature control structure to nap the filaments after they have been twisted by a doubling machine. The filaments, unwound from the doubling machine's bobbins, are first twisted and then sprayed with an oiling agent. The napping and temperature control structure is then used to nap the filaments, and phase change microcapsules are used to regulate the temperature of the grinding wheel, ensuring a stable surface temperature during the napping process. This results in a controllable formation of a uniform nap layer on the filament surface, giving the filament a cotton-like feel.

[0003] The processing method of this cotton-type filament sewing thread has the following shortcomings: First, it lubricates the yarn by spraying oil onto it. However, since the yarn itself is very fine, it is necessary to ensure that the oil adheres evenly to the yarn during the oiling process. This inevitably leads to a large waste of oil and makes it difficult to control the amount of oil adhering to the yarn. Second, it regulates the temperature of the grinding wheel by using phase change microcapsules to absorb and release heat. However, the heat released by the yarn itself rubbing against the grinding wheel is uncertain, and the timing of heat absorption or release by the phase change microcapsules and the amount of heat absorbed or released are also uncontrollable. Therefore, it is difficult to ensure the stability of the yarn temperature during the yarn abrasion process. Summary of the Invention

[0004] Therefore, it is necessary to provide a processing equipment and method for cotton-type filament sewing thread to address the existing technical problems.

[0005] To address the problems in the existing technology, the technical solution adopted by this invention is as follows:

[0006] A processing device for cotton-type filament sewing thread includes a frame and a yarn-drawing bobbin, a reciprocating yarn guide, and a yarn-taking bobbin sequentially arranged on the frame. Between the yarn-drawing bobbin and the reciprocating yarn guide, an oiling component for adding oil to the yarn and a yarn-brushing and temperature-controlling component for napping and controlling the temperature of the yarn are sequentially arranged. The oiling component includes a counter-moving mechanism fixed to the frame and two oiling rollers and a winding wheel arranged on the counter-moving mechanism. The counter-moving mechanism has two output ends that can move in opposite directions in the horizontal direction. The two oiling rollers are respectively arranged on the two output ends of the counter-moving mechanism. The two winding wheels are respectively vertically connected to the upper and lower parts of the counter-moving mechanism and located between the two oiling rollers. Each oiling roller includes an inner oil delivery cylinder fixedly arranged on the corresponding output end of the counter-moving mechanism. An external oil delivery cylinder is coaxially mounted on an internal oil delivery cylinder, and an oil-coated soft sleeve is coaxially wrapped around the external oil delivery cylinder. The external oil delivery cylinder is dynamically sealed to the internal oil delivery cylinder. Several oil passage holes communicating with their inner cavities are opened on the outer walls of both the internal and external oil delivery cylinders. Each internal oil delivery cylinder is provided with an oil inlet for delivering oil into its inner cavity. After the yarn is fed out and onto the yarn bobbin, it passes successively over the lower winding wheel, the lower oil-coated soft sleeve, the upper oil-coated soft sleeve, and the upper winding wheel. The abrasive temperature control assembly includes two adaptive cooling abrasives mounted on the frame and capable of adjusting their spacing to gradually clamp the yarn. Each adaptive cooling abrasive includes several V-shaped abrasive discs arranged at equal intervals in the vertical direction for rubbing the yarn, heat-conducting fins for cooling the V-shaped abrasive discs, and a coolant circulation pipe for assisting the heat-conducting fins in heat dissipation.

[0007] Preferably, the opposing movement mechanism includes two sets of limiting members symmetrically arranged at both ends of the oil-coating roller, two bidirectional lead screws corresponding to the two sets of limiting members, and a mini motor for driving the two bidirectional lead screws to rotate synchronously. The axial direction of the bidirectional lead screws is perpendicular to the axial direction of the oil-coating roller, and both the bidirectional lead screws and the oil-coating roller are horizontal. Each set of limiting members includes two first vertical plates and a first horizontal shaft. The two first vertical plates are symmetrically arranged at both ends of the bidirectional lead screw and fixed to the frame. The two first horizontal shafts are horizontally symmetrically arranged above and below the corresponding bidirectional lead screw, and both ends of each first horizontal shaft are fixed to the two first vertical plates. The two ends of the bidirectional lead screw are respectively axially connected to the center of the two first vertical plates. The mini motor is fixedly mounted on one of the first vertical plates. The output shaft of the mini motor is coaxially fixed to the corresponding bidirectional lead screw. The same end of the two bidirectional lead screws is connected by belt drive. Both ends of each inner oil delivery cylinder are fixedly connected to two second vertical plates corresponding to two sets of limiting parts. Each second vertical plate is fixedly connected to a threaded sleeve and a linear bearing. The threaded sleeve is threadedly engaged with the corresponding bidirectional lead screw. The two linear bearings on the upper oil delivery roller are coaxially slidably mounted on the two upper first horizontal shafts, and the two linear bearings on the lower oil delivery roller are coaxially slidably mounted on the two lower first horizontal shafts. A convex ring is formed in the middle of the bidirectional lead screw. Two external threads with opposite directions and symmetrical about the convex ring are formed on the outer wall of the bidirectional lead screw. The two oil delivery rollers are respectively corresponding to the two external threads with opposite directions and are symmetrically arranged on both sides of the convex ring.

[0008] Preferably, the two ends of the inner oil delivery cylinder are fixedly connected to the two second vertical plates through two bearingless shaft seats. The oil inlet is an oil inlet pipe formed at both ends of the inner oil delivery cylinder. The outer oil delivery cylinder has two stepped sections formed inside. An oil changing chamber is formed between the inner wall of the outer oil delivery cylinder, the two stepped sections, and the outer wall of the outer oil delivery cylinder. Each stepped section is coaxially provided with a sealing ring that is dynamically sealed to the outer wall of the outer oil delivery cylinder. Several oil passage holes are opened at the corresponding oil changing chamber positions of the inner and outer oil delivery cylinders. Two sealing bearings are also provided on the opposite sides of the two stepped sections to keep the inner and outer oil delivery cylinders coaxially connected. The oil-attached soft sleeve is coaxially fixedly sleeved on the corresponding oil changing chamber position of the outer oil delivery cylinder.

[0009] Preferably, a first bracket is fixedly connected to both the upper and lower first horizontal shafts, and a second horizontal shaft is coaxially fixed to the winding wheel. The second horizontal shaft is axially mounted on the corresponding first bracket through two bearing seats. Each first bracket is also provided with a clearance groove for avoiding the yarn.

[0010] Preferably, several V-shaped grinding discs are formed on the opposite ends of two adaptive cooling grinding molds, and the several V-shaped grinding discs on the two adaptive cooling grinding molds are staggered. Heat-conducting fins are formed on the opposite sides of the two adaptive cooling grinding molds. Coolant circulation pipes are coiled and inserted into the heat-conducting fins in a serpentine shape. Each coolant circulation pipe has an inlet and an outlet formed at both ends. A second bracket fixed to the frame is fixed to one of the adaptive cooling grinding molds, and the outlet of the coolant circulation pipe on this side is connected to the inlet of the other coolant circulation pipe through a hose. The adaptive cooling grinding mold not connected to the second bracket is slidably set on the adaptive cooling grinding mold connected to the second bracket.

[0011] Preferably, the adaptive cooling abrasive fixed to the second bracket has a bolt on the shaft connection that is fixed to two third horizontal shafts and axially limited, and another adaptive cooling abrasive is slidably disposed on the two third horizontal shafts. The threaded end of the bolt passes through the adaptive cooling abrasive and is threadedly connected to it, and the threaded end of the bolt is also threadedly connected to two mutually locking limit nuts.

[0012] Preferably, wear-resistant heat-conducting sheets are fixedly connected to the opposing ends of several V-shaped grinding discs on the two adaptive cooling abrasives, and the several V-shaped grinding discs are all horizontally arranged.

[0013] A method of using a cotton-type filament sewing thread processing device, comprising the above-mentioned cotton-type filament sewing thread processing device, the method of using the device includes the following steps:

[0014] S1. Before the yarn is brushed, the equipment is adjusted according to the material and size of the yarn. During the adjustment, the yarn sent out to the yarn bobbin passes through the lower winding wheel, the lower oiled soft sleeve, the upper oiled soft sleeve and the upper winding wheel in sequence. Then the yarn passes between several V-shaped grinding discs and is wound onto the take-up bobbin after passing through the reciprocating yarn guide.

[0015] S2, adjust the distance between the two adaptive cooling abrasives so that several V-shaped abrasive discs clamp the yarn, and adjust the rotation speed of the take-up drum to ensure that the yarn can form a roughened layer on the surface after being rubbed by the two adaptive cooling abrasives;

[0016] S3, adjust the distance between the two oiling rollers so that the yarn can be coated with an appropriate amount of oil after passing over the two oiling rollers;

[0017] S4, repeat steps S2 and S3, so that the yarn can form a roughened layer after being properly rubbed with several V-shaped abrasive discs, and the temperature itself will not be too high or too low.

[0018] S5. After completing the above debugging steps, maintain the spacing between the two oil-coated rollers and the spacing between the two adaptive cooling grinding discs, and officially begin the yarn abrasion operation.

[0019] The beneficial effects of this invention compared to the prior art are:

[0020] Firstly, in this invention, the yarn is passed around two oiling rollers, and the part of the yarn that comes into contact with the oiling sleeve on the oiling roller automatically absorbs the oil on the oiling sleeve, thereby applying the oil to the yarn. Moreover, the fact that both sides of the yarn come into contact with the two oiling sleeves respectively ensures that the entire yarn can absorb the oil, which can greatly avoid the waste of oil and uneven application of oil on the yarn.

[0021] Secondly, in this invention, heat-conducting fins are used in conjunction with a coolant circulation pipe to dissipate heat and cool the adaptive cooling abrasive, thereby absorbing the heat on the adaptive cooling abrasive and allowing the heat generated by yarn friction to be actively conducted to the adaptive cooling abrasive, thereby reducing the temperature of the yarn during friction. By controlling the temperature and flow rate of the coolant in the coolant circulation pipe, the temperature during the yarn friction process is indirectly controlled, making the temperature during the yarn friction process controllable.

[0022] Thirdly, the distance between the two oil-coating rollers in this invention is adjustable. By adjusting the distance between the two oil-coating rollers, the contact length between the yarn and the two oil-coating sleeves before friction is changed, thereby changing the amount of oil adhering to the yarn, thus ensuring that the amount of oil adhering to the yarn is stable and controllable.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 8 The device for processing cotton-type filament sewing thread includes a frame and a yarn-drawing bobbin, a reciprocating yarn guide, and a yarn-taking bobbin arranged sequentially on the frame. Between the yarn-drawing bobbin and the reciprocating yarn guide, there are also sequentially arranged an oiling component for adding oil to the yarn 1 and a napping and temperature-controlling component for napping and controlling the temperature of the yarn 1. The oiling component includes a counter-moving mechanism 2 fixed to the frame, two oiling rollers 3 and a winding wheel 4 arranged on the counter-moving mechanism 2. The counter-moving mechanism 2 has two output ends that can move in opposite directions in the horizontal direction. The two oiling rollers 3 are respectively arranged on the two output ends of the counter-moving mechanism 2. The two winding wheels 4 are respectively vertically connected to the upper and lower parts of the counter-moving mechanism 2 and located between the two oiling rollers 3. Each oiling roller 3 includes an inner oil delivery cylinder 5 fixedly arranged on the corresponding output end of the counter-moving mechanism 2 and a coaxially connected... An external oil delivery cylinder 6 is placed on the internal oil delivery cylinder 5, and an oil-coated soft sleeve 7 is coaxially wrapped on the external oil delivery cylinder 6. The external oil delivery cylinder 6 is dynamically sealed to the internal oil delivery cylinder 5. Several oil passage holes 8 are opened on the outer walls of both the internal oil delivery cylinder 5 and the external oil delivery cylinder 6 to connect their inner cavities. Each internal oil delivery cylinder 5 is provided with an oil inlet for delivering oil into its inner cavity. After the yarn 1 is delivered and passed through the yarn bobbin, it passes successively around the lower winding wheel 4, the lower oil-coated soft sleeve 7, the upper oil-coated soft sleeve 7, and the upper winding wheel 4. The abrasive temperature control assembly includes two adaptive cooling abrasives 9 set on the frame and capable of adjusting the spacing to gradually clamp the yarn 1. Each adaptive cooling abrasive 9 includes several V-shaped abrasive discs 10 arranged at equal intervals in the vertical direction for rubbing the yarn 1, heat-conducting fins 11 for cooling the several V-shaped abrasive discs 10, and a coolant circulation pipe 12 for assisting the heat-conducting fins 11 in dissipating heat.

[0034] The frame, yarn dowel, reciprocating yarn guide, and take-up bobbin are not shown in the figure. The yarn dowel is used to twist multiple single yarns 1 together into a single long yarn. The reciprocating yarn guide is used to reciprocately wind the yarn 1 onto the take-up bobbin. The take-up bobbin is used to rotate and take up the finished long yarn. The yarn 1 is continuously wound onto the take-up bobbin by the yarn take-up bobbin. The two output ends of the opposing moving mechanism 2 can drive the two oiling rollers 3 to move towards each other or away from each other. After the yarn 1 passes over the lower winding wheel 4, it winds obliquely upwards onto the lower oiling roller 3. Then, after passing out of the lower oiling roller 3, it winds obliquely upwards onto the upper oiling roller 3. Finally, it winds out of the upper oiling roller 3. After the oil-coating roller 3, the yarn 1 is wound diagonally upwards onto the upper winding wheel 4, and finally, after exiting the upper winding wheel 4, it is vertically fed upwards to the adaptive cooling mold 9. The two winding wheels 4 can only rotate in place, thus limiting the movement of the yarn 1. When the two oil-coating rollers 3 move away from each other, the length of the contact portion between the yarn 1 and the oil-coating sleeve 7 is increased. Similarly, when the two oil-coating rollers 3 move closer to each other, the length of the contact portion between the yarn 1 and the oil-coating sleeve 7 is decreased. Since the oil delivery speed at the oil inlet of each inner oil delivery cylinder 5 is constant, the length of the contact portion between the yarn 1 and the two oil-coating sleeves 7 can be appropriately extended or shortened. This allows for the adjustment of the amount of oil applied to yarn 1, ensuring both a certain smoothness on the yarn 1 surface to prevent static electricity and to prevent excessive oil from negatively impacting subsequent friction. Two oiling rollers 3 wind the yarn 1 from different directions, ensuring that the yarn 1 surface is coated with oil. After being fed out by the upper winding wheel 4, the yarn 1 passes vertically upwards between the two V-shaped grinding discs 10, thus rubbing against them and forming a roughened layer on the outer surface of the yarn 1. During the friction between the yarn 1 and the V-shaped grinding discs 10, a roughened layer is formed. The heat generated can be cooled in time by the heat-conducting fins 11 and the coolant circulation pipe 12. At the same time, the V-shaped grinding disc 10 can also absorb the heat on the yarn 1 in time after cooling down, so as to prevent damage to the yarn 1. Before the yarn 1 is processed, the equipment needs to be debugged. During the debugging, the distance between the two oiling rollers 3 is adjusted according to the size and material of the yarn 1, so that after the yarn 1 passes through the oiling sleeve 7, an appropriate amount of uniform oil is attached to the yarn 1. At the same time, the distance between the two adaptive cooling abrasives 9 is adjusted so that the yarn 1 rubs appropriately with several V-shaped abrasives.

[0035] In order to drive the two oil-coated rollers 3 to move in opposite directions through the bidirectional moving mechanism, the following features are specifically designed:

[0036] The opposing moving mechanism 2 includes two sets of limiting members symmetrically arranged at both ends of the oil-coating roller 3, two bidirectional lead screws 13 corresponding to the two sets of limiting members, and a mini motor 14 for driving the two bidirectional lead screws 13 to rotate synchronously. The axial direction of the bidirectional lead screws 13 is perpendicular to the axial direction of the oil-coating roller 3, and both the bidirectional lead screws 13 and the oil-coating roller 3 are in a horizontal state. Each set of limiting members includes two first vertical plates 15 and a first horizontal shaft 16. The two first vertical plates 15 are symmetrically arranged at both ends of the bidirectional lead screw 13 and are fixedly connected to the frame. The two first horizontal shafts 16 are horizontally symmetrically arranged above and below the corresponding bidirectional lead screw 13, and both ends of each first horizontal shaft 16 are fixedly connected to the two first vertical plates 15. The two ends of the bidirectional lead screw 13 are respectively axially connected to the center of the two first vertical plates 15. The mini motor 14 is fixedly mounted on one of the first vertical plates 15. The output shaft of the mini motor 14 is coaxially fixed to the corresponding bidirectional lead screw 13. The same end of the two bidirectional lead screws 13 is connected by belt drive. Both ends of each inner oil delivery cylinder 5 are fixedly connected to two second vertical plates 17 corresponding to two sets of limiting parts. Each second vertical plate 17 is fixedly connected to a threaded sleeve 18 and a linear bearing 19. The threaded sleeve 18 is threadedly engaged with the corresponding bidirectional lead screw 13. The two linear bearings 19 on the upper oil roller 3 are coaxially slidably mounted on the two upper first horizontal shafts 16. The two linear bearings 19 on the lower oil roller 3 are coaxially slidably mounted on the two lower first horizontal shafts 16. A convex ring is formed in the middle of the bidirectional lead screw 13. Two external threads with opposite directions and symmetrical about the convex ring are formed on the outer wall of the bidirectional lead screw 13. The two oil rollers 3 are respectively corresponding to the two external threads with opposite directions and are symmetrically arranged on both sides of the convex ring.

[0037] One end of each second vertical plate 17 is limited by a linear bearing 19 and a first horizontal shaft 16, while the other end is threadedly connected to the corresponding end of a double-acting screw 13 via a threaded sleeve 18. This achieves the limitation of the second vertical plate 17. After the two second vertical plates 17 on the corresponding side are fixedly connected to the inner oil delivery cylinder 5, under the joint limitation of the inner oil delivery cylinder 5, the two second vertical plates 17, the two double-acting screws 13, the two linear bearings 19, the two threaded sleeves 18, and the four first horizontal shafts 16, when the two double-acting screws 13 rotate synchronously, the inner oil delivery cylinder 5 can move along the axial direction of the double-acting screws 13. The mini motor 14 has a self-locking function. In conjunction with the double-acting screws 13, when the output shaft of the mini motor 14 does not rotate, it can ensure that the distance between the two oil-attached rollers 3 remains unchanged.

[0038] In order to apply the oil to the yarn 1 by the oiling roller 3, the following features are specifically designed:

[0039] The two ends of the inner oil delivery cylinder 5 are fixedly connected to the two second vertical plates 17 through two bearingless bearing seats 20. The oil inlet is an oil inlet pipe 21 formed at both ends of the inner oil delivery cylinder 5. The outer oil delivery cylinder 6 has two stepped parts 22 formed inside. An oil changing chamber 23 is formed between the inner wall of the outer oil delivery cylinder 6, the two stepped parts 22 and the outer wall of the outer oil delivery cylinder 6. Each stepped part 22 is coaxially provided with a sealing ring 24 that is dynamically sealed to the outer wall of the outer oil delivery cylinder 6. Several oil passage holes 8 are opened at the positions of the inner oil delivery cylinder 5 and the outer oil delivery cylinder 6 corresponding to the oil changing chamber 23. Two sealing bearings 25 are also provided on the opposite sides of the two stepped parts 22 to keep the inner oil delivery cylinder 5 and the outer oil delivery cylinder 6 coaxially connected. The oil-attached soft sleeve 7 is coaxially fixedly sleeved on the position of the outer oil delivery cylinder 6 corresponding to the oil changing chamber 23.

[0040] The oil-coated sleeve 7 can be a cylindrical sponge with several small-diameter oil passage holes 8. After the oil is sent into the inner oil delivery cylinder 5 through the two oil inlet pipes 21, it will not actively pass through the oil passage holes 8 without external pressure. After a certain amount of oil is sent into the two oil inlet pipes 21, the oil will gradually flow into the oil changing chamber 23. After the oil gradually fills the oil changing chamber 23, the oil-coated sleeve 7 on the outer oil delivery cylinder 6 will automatically absorb the oil in the oil changing chamber 23 through the oil passage holes 8. After the yarn 1 passes around the oil-coated sleeve 7, the oil on the oil-coated sleeve 7 will adhere to the yarn 1. During equipment debugging, the speed of oil delivery through the two oil inlet pipes 21 is adjusted according to the speed of yarn 1 to match the speed of oil absorption by the yarn 1. The sealing ring 24 and the sealing bearing 25 are used to ensure that the oil in the oil changing chamber 23 does not leak out.

[0041] In order to mount the winding wheel 4 shaft onto the corresponding opposing moving mechanism 2, the following features are specifically provided:

[0042] A first bracket 26 is fixedly connected to both the upper and lower first horizontal shafts 16. A second horizontal shaft 27 is coaxially fixed to the winding wheel 4, and the second horizontal shaft 27 is axially mounted on the corresponding first bracket 26 through two bearing seats 28. Each first bracket 26 is also provided with a clearance groove 29 for avoiding the yarn 1.

[0043] The two first supports, one above the other, are 26 in number. Figure 2 As shown in the diagram, the winding wheel 4 is mounted on the first bracket 26 via the second horizontal shaft 27 and the bearing seat 28, thereby appropriately changing the direction of the yarn 1. This ensures that when the two oiling rollers 3 move towards each other, the length of the part of the yarn 1 that is coiled around the oiling sleeve 7 changes accordingly, and the yarn 1 can remain vertical when entering and exiting the oiling assembly.

[0044] In order to dissipate heat from the heat-conducting fins 11 through the coolant circulation pipe 12, the following features are specifically provided:

[0045] Several V-shaped grinding discs 10 are formed on the opposite ends of two adaptive cooling grinding molds 9, and the V-shaped grinding discs 10 on the two adaptive cooling grinding molds 9 are staggered. Heat-conducting fins 11 are formed on the opposite sides of the two adaptive cooling grinding molds 9. Coolant circulation pipes 12 are coiled and inserted into the heat-conducting fins 11 in a serpentine shape. Each coolant circulation pipe 12 has an inlet and an outlet formed at both ends. A second bracket 30 fixedly connected to the frame is fixed to one of the adaptive cooling grinding molds 9, and the outlet of the coolant circulation pipe 12 on this side is connected to the inlet of the other coolant circulation pipe 12 through a hose. The adaptive cooling grinding mold 9 not connected to the second bracket 30 is slidably set on the adaptive cooling grinding mold 9 connected to the second bracket 30.

[0046] The hose is not shown in the figure. The inlet and outlet are not marked. A storage tank for circulating coolant is installed on the frame (not shown in the figure). A miniature diaphragm pump (not shown in the figure) is also installed on the second bracket 30. The inlet of the miniature diaphragm pump is connected to the storage tank, and the outlet of the miniature diaphragm pump is connected to the inlet of the coolant circulation pipe 12 on the corresponding adaptive cooling mold 9. The miniature diaphragm pump draws coolant from the storage tank and sends it into the coolant circulation pipe 12 through the corresponding inlet, then sends it into another coolant circulation pipe 12 through the corresponding outlet and the inlet of another coolant circulation pipe 12, and finally flows out through the outlet of the other coolant circulation pipe 12. Each adaptive cooling mold 9 has two through holes. The hose passes through the two through holes on the corresponding side to avoid contact with the coolant. The yarn 1 is not connected to the outlet of the adaptive cooling abrasive 9, which is not connected to the second support 30. A return pipe (not shown in the figure) is connected to the liquid storage tank. The return pipe passes through two through holes on the corresponding side to avoid conflict with the yarn 1. The coolant flowing back in the return pipe can be cooled again after passing through the liquid storage tank. The input shaft of the micro diaphragm pump can be connected to the output shaft of the take-up bobbin. The speed of the take-up bobbin determines the speed of yarn 1. The faster the yarn 1 moves, the greater the heat generated by its friction with several V-shaped abrasive plates 10. Therefore, after the rotation of the take-up bobbin is associated with the rotation of the input shaft of the micro diaphragm pump, it is ensured that when the heat generated by the friction between the yarn 1 and the V-shaped abrasive plates 10 is greater, the speed at which the micro diaphragm pump delivers coolant is faster, that is, the heat on the V-shaped abrasive plates 10 and the yarn 1 is absorbed faster.

[0047] In order to enable the two adaptive cooling abrasives 9 to move towards each other and adjust the spacing to ensure proper friction with the yarn 1 after clamping, the following features are specifically designed:

[0048] The adaptive cooling abrasive 9, which is fixed to the second bracket 30, has two third horizontal shafts 31 fixed to it and is axially limited by a bolt 32. The other adaptive cooling abrasive 9 is slidably mounted on the two third horizontal shafts 31. The threaded end of the bolt 32 passes through the adaptive cooling abrasive 9 and is threadedly connected to it. The threaded end of the bolt 32 is also threadedly connected to two mutually locking limit nuts 33.

[0049] Since the axial limiting shaft of bolt 32 is set on the corresponding adaptive cooling abrasive 9, and the threaded end of bolt 32 is threadedly connected to another adaptive cooling abrasive 9, together with the limiting of the two adaptive cooling abrasives 9 by the two third horizontal shafts 31, it is ensured that the corresponding adaptive cooling can only move axially along the third horizontal shaft 31. Therefore, after bolt 32 rotates, it can drive the corresponding adaptive cooling abrasive 9 to move closer to or away from the other adaptive cooling abrasive 9, thus adjusting the distance between the two adaptive cooling abrasives 9.

[0050] In order to enable the V-shaped grinding disc 10 to better clamp the yarn 1 and rub against the yarn 1, the following features are specifically designed:

[0051] Wear-resistant heat-conducting plates 34 are fixedly connected to the opposing ends of several V-shaped grinding discs 10 on the two adaptive cooling grinding molds 9, and the several V-shaped grinding discs 10 are all set horizontally.

[0052] The opposing ends of several V-shaped grinding discs 10 on two adaptive cooling grinding wheels 9 are... Figure 4 The V-shaped structure shown allows the two adaptive cooling abrasives 9 to gradually clamp the yarn 1 as they approach each other, thus generating friction with the yarn 1. The wear-resistant heat-conducting sheet 34 is made of a material with high thermal conductivity and wear resistance, and the adaptive cooling abrasives 9 are also made of a material with high thermal conductivity (such as pure copper). This effectively reduces the wear of the wear-resistant heat-conducting sheet 34, and the heat generated by friction can be discharged in time through the heat-conducting fins 11.

[0053] A method of using a cotton-type filament sewing thread processing device, comprising the above-mentioned cotton-type filament sewing thread processing device, the method comprising the following steps:

[0054] S1. Before the yarn 1 is brushed, the equipment is adjusted according to the material and size of the yarn 1. During the adjustment, the yarn 1 sent out to the yarn bobbin passes through the lower winding wheel 4, the lower oiled soft sleeve 7, the upper oiled soft sleeve 7 and the upper winding wheel 4 in succession. Then, the yarn 1 passes between several V-shaped grinding discs 10 and is wound onto the take-up bobbin after passing through the reciprocating yarn guide.

[0055] S2, adjust the distance between the two adaptive cooling abrasives 9 so that several V-shaped abrasive discs 10 clamp the yarn 1, and adjust the rotation speed of the take-up drum to ensure that the yarn 1 can form a roughened layer on the surface after being rubbed by the two adaptive cooling abrasives 9.

[0056] S3, adjust the distance between the two oiling rollers 3 so that the yarn 1 can be coated with an appropriate amount of oil after passing over the two oiling rollers 3;

[0057] S4. Repeat steps S2 and S3 so that yarn 1 can form a roughened layer after being properly rubbed with several V-shaped abrasive discs 10, and its temperature will not be too high or too low.

[0058] S5. After completing the above debugging steps, maintain the distance between the two oil-coated rollers 3 and the distance between the two adaptive cooling grinding discs, and officially begin the abrasion operation on the yarn 1.

[0059] Working principle: The frame, yarn dowel, reciprocating yarn guide, and take-up bobbin are not shown in the figure. The yarn dowel is used to twist multiple single yarns 1 together into a single long yarn. The reciprocating yarn guide is used to reciprocately wind the yarn 1 onto the take-up bobbin. The take-up bobbin is used to rotate and take up the finished long yarn. The yarn 1 is driven by the take-up bobbin to continuously wind onto the take-up bobbin. The two output ends of the opposing movement mechanism 2 can drive the two oiling rollers 3 to move towards each other or away from each other. After the yarn 1 passes over the lower winding wheel 4, it winds obliquely upwards onto the lower oiling roller 3. Then, after passing out of the lower oiling roller 3, it winds obliquely upwards onto the upper oiling roller 3. After passing through the upper oiling roller 3, the yarn 1 is then wound diagonally upwards to the upper winding wheel 4, and finally, after passing through the upper winding wheel 4, it is vertically fed upwards to the adaptive cooling mold 9. The two winding wheels 4 can only rotate in place, thus limiting the movement of the yarn 1. When the two oiling rollers 3 move away from each other, the length of the contact portion between the yarn 1 and the oiling sleeve 7 is increased. Similarly, when the two oiling rollers 3 move closer to each other, the length of the contact portion between the yarn 1 and the oiling sleeve 7 is decreased. Since the oil delivery speed at the oil inlet of each inner oil delivery cylinder 5 is constant, the length of the contact portion between the yarn 1 and the two oiling sleeves 7 can be appropriately extended or shortened. The degree of oil application on yarn 1 can be adjusted to change the amount of oil applied, thus ensuring that the surface of yarn 1 maintains a certain smoothness and is not prone to static electricity, while also preventing excessive oil from causing poor subsequent friction. Two oiling rollers 3 wind yarn 1 from different directions, ensuring that the surface of yarn 1 is coated with oil. After being fed out by the upper winding wheel 4, yarn 1 passes vertically upward between the two V-shaped abrasive discs 10, thus rubbing against them and forming a roughened layer on the outer surface of yarn 1. During the friction between yarn 1 and the V-shaped abrasive discs 10... The heat generated can be cooled in time by the heat-conducting fins 11 and the coolant circulation pipe 12. At the same time, the V-shaped grinding disc 10 can also absorb the heat on the yarn 1 in time after cooling down, preventing damage to the yarn 1. Before the yarn 1 is processed, the equipment needs to be debugged. During the debugging, the distance between the two oiling rollers 3 is adjusted according to the size and material of the yarn 1, so that after the yarn 1 passes through the oiling sleeve 7, an appropriate amount of uniform oil is attached to the yarn 1. At the same time, the distance between the two adaptive cooling abrasives 9 is adjusted so that the yarn 1 rubs appropriately with several V-shaped abrasives.
