Description

Technical Field

[0001] The invention belongs to the technical field of heat setting machines, in particular to a heat setting treatment device for nylon monofilament production and an operating method thereof. Background Art

[0002] As a polymer material with high strength, wear resistance and good mechanical properties, nylon yarn is widely used in the fields of textiles, automobiles, machinery, etc. Heat setting is an important step in the processing of nylon yarns. It aims to fix its shape and size by heating and maintaining it for a certain period of time. A heat setting machine is generally used for heat setting of nylon yarns. A heat setting machine is generally composed of several parts such as a heating device, a transmission device and a cooling device. After the nylon yarn is heated by the heating device, it is guided out by the transmission device and quickly cooled and set by the cooling device. At present, the cooling devices on the heat setting machines are mostly divided into two structures: water cooling and air cooling. The water cooling structure is more popular because of its faster cooling speed and lower investment cost.

[0003] In the prior art, the water cooling structure on the heat setting machine is mostly a water cooling tank. After the nylon yarn is heated and discharged, it directly enters the cold water in the water cooling tank to complete rapid cooling. However, the nylon yarn will be in a soaked state after passing through the water cooling tank. This soaked state will affect the subsequent processing and use of the nylon yarn, and further affect the quality and performance of the nylon yarn. In addition, after the water cooling tank has been used for a period of time, impurities usually float on the surface. This causes the nylon yarn to be attached by the impurities floating on the water surface when it is discharged from the water cooling tank, and the staff needs to clean it again, which greatly wastes time and energy.

[0004] To this end, the present invention provides a heat setting treatment device for producing nylon monofilament and an operating method thereof. Summary of the invention

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 11As shown, a heat setting treatment device for nylon monofilament production described in an embodiment of the present invention comprises a heating box 1, a water cooling trough 2 is arranged on one side of the heating box 1, guide rollers 3 are arranged on the top of both sides of the water cooling trough 2, a U-shaped frame 4 is arranged on the top of the side of the water cooling trough 2 away from the heating box 1, a mounting roller 5 is rotatably connected to the U-shaped frame 4, a plurality of fixing plates 6 are detachably connected to the mounting roller 5, a sponge pad 7 is evenly fixed to the fixing plate 6, an angle adjustment mechanism is arranged on the U-shaped frame 4, the angle adjustment mechanism controls the rotation angle of the mounting roller 5, a spray mechanism is arranged on the top of the side of the water cooling trough 2 close to the heating box 1; during operation, when the nylon thread is heated by the heating box 1 and then transmitted to the water cooling trough 2, the guide rollers 3 arranged on both sides of the top of the water cooling trough 2 can assist in guiding the transmission of the nylon thread, and when the nylon thread passes through the water cooling trough 2, the spray mechanism above the water cooling trough 2 will spray the nylon thread passing downward The nylon thread sprays cold water, and the cold water falls into the water-cooling tank 2 after moistening and cooling the nylon thread. When the cooled nylon thread passes through the installation roller 5, it will contact the sponge pad 7 on the fixed plate 6. The sponge pad 7 can absorb the moisture on the surface of the nylon thread to achieve rapid drying, effectively avoiding the situation where the quality and performance of the nylon thread are affected after being soaked in water in the water-cooling tank 2. When the sponge pad 7 in contact with the nylon thread has a high water content after being used for a period of time, the installation roller 5 can be driven to rotate through the angle adjustment mechanism to rotate the fixed plate 6 that is not in contact with the nylon thread to the top, so that the new sponge pad 7 can continue to dry the nylon thread, preventing the water absorption effect of a sponge pad 7 from decreasing after long-term use. By setting up a spraying mechanism above the water-cooling tank 2, the nylon thread can be prevented from contacting with floating impurities in the water-cooling tank 2, and the nylon thread can be flushed at the same time.

[0023] The angle adjustment mechanism includes a motor 8, a worm 9 and a worm wheel 10. The motor 8 is fixedly installed on the inner wall of one side of the U-shaped frame 4, the output end of the motor 8 is fixedly connected to the worm 9, one end of the mounting roller 5 is fixedly connected to the worm wheel 10, and the worm wheel 10 is transmission connected to the worm 9; during operation, when the angle of the mounting roller 5 needs to be adjusted, the motor 8 is started, and the worm 9 is driven to rotate by the output shaft of the motor 8, so that the worm wheel 10 rotates accordingly, and then the mounting roller 5 starts to rotate until the new fixed plate 6 away from the side of the heating box 1 rotates to the top, that is, when the new sponge pad 7 contacts the nylon wire, the motor 8 stops rotating to achieve precise angle adjustment control.

[0024] A special-shaped plate 12 is symmetrically fixed to one side of the U-shaped frame 4 close to the heating box 1, an arc-shaped pressure plate 14 is arranged between the two special-shaped plates 12, through holes are evenly arranged on the arc-shaped pressure plate 14, connecting rods 15 are fixed to both sides of the arc-shaped pressure plate 14, and brackets 13 are fixed to the opposite sides of the two special-shaped plates 12, the connecting rods 15 are slidably connected to the brackets 13, a spring 16 is fixed between one end of the connecting rod 15 away from the arc-shaped pressure plate 14 and the bracket 13, and a guide component is arranged between the special-shaped plate 12 on one side of the motor 8 and the arc-shaped pressure plate 14; when the motor 8 starts working, the arc-shaped pressure plate 14 is moved away from the installation under the action of the guide component. The roller 5 is installed. At the same time, the connecting rod 15 slides along the bracket 13 and compresses the spring 16. The sponge pad 7, which has been pressed out of moisture by the arc-shaped pressure plate 14, rotates to the side away from the heating box 1, and the sponge pad 7 that has absorbed the moisture on the surface of the nylon thread rotates to the position corresponding to the arc-shaped pressure plate 14. When the motor 8 stops, the connecting rod 15 is reset under the elastic force of the spring 16, and the arc-shaped pressure plate 14 is reset accordingly, and the sponge pad 7 that has absorbed the moisture on the surface of the nylon thread that rotates here is filtered to squeeze out the moisture contained therein, so that the sponge pad 7 can continue to dry the nylon thread after rotating to the top of the installation roller 5.

[0025] The guide assembly includes a fixed sleeve 17 and a rack 20. The fixed sleeve 17 is fixedly connected to the connecting rod 15 located on one side of the motor 8. The end of the worm 9 away from the motor 8 is fixedly connected to the gear 11. One side of the gear 11 is meshed and connected to the rack 20. The end of the rack 20 is fixedly connected to the connecting rod 2 19. The end of the connecting rod 2 19 away from the rack 20 extends into the inner cavity of the fixed sleeve 17 and is fixedly connected to the spring 2 18. The end of the spring 2 18 away from the connecting rod 2 19 is connected to the fixed sleeve 17. The inner wall is fixed, one end of the connecting rod 29 away from the rack 20 is slidably connected to the inner cavity of the fixed sleeve 17, an elastic member is provided on the top of the rack 20, and a guide groove 24 and a guide groove 25 are provided at the bottom of the special-shaped plate 12 located on one side of the motor 8. The guide groove 24 is connected to the guide groove 25, and the guide groove 24 is parallel to the rack 20. The angle between the guide groove 25 and the guide groove 24 is an acute angle. The elastic member is slidably connected to the guide groove 24 and the guide groove 25; when working When the motor 8 drives the worm 9 to rotate, the gear 11 drives the rack 20 to slide, so that the connecting rod 19 cooperates with the fixed sleeve 17 to drive the arc pressure plate 14 away from the installation roller 5. At the same time, the elastic member on the rack 20 slides along the guide groove 1 24 toward the connection between it and the guide groove 2 25 until the motor 8 stops. At this time, the elastic member is located in the guide groove 25. When the arc pressure plate 14 is reset under the elastic force of the spring 16, the elastic member slides in the guide groove 25. The rack 20 does not contact the gear 11, and the connecting rod 19 compresses the spring 18 in the fixed sleeve 17 until the elastic member slides out of the guide groove 25. The connecting rod 19 drives the rack 20 to mesh with the gear 11 again under the elastic force of the spring 18 to achieve reset, and so on, so that when the mounting roller 5 rotates, the arc-shaped pressure plate 14 does not contact and rub with the sponge pad 7. When the mounting roller 5 stops rotating, the arc-shaped pressure plate 14 can be reset to filter the sponge pad 7 containing water.

[0026] The elastic member includes a guide sleeve 21 and a guide block 22. The top of the rack 20 is fixedly connected with the guide sleeve 21.

The top of the guide block 22 extends to the outside of the guide sleeve 21. The guide block 22 is adapted to the guide groove 1 24 and the guide groove 2 25. The groove depth of the guide groove 1 24 is less than the groove depth of the guide groove 25. The side of the guide groove 25 away from the guide groove 1 24 is provided with an inclined surface. When working, when the guide block 22 slides in the guide groove 1 24, Spring three 23 is in a compressed state until the guide block 22 slides from guide groove one 24 into guide groove two 25. Because the groove depth of guide groove two 25 is greater than that of guide groove one 24, the guide block 22 can quickly fit with guide groove two 25 under the elastic force of spring three 23. When the guide block 22 slides to the inclined surface in guide groove two 25, spring three 23 is compressed again until the guide block 22 slides out of guide groove two 25 and then returns to slide to guide groove one 24. At this time, the guide block 22 quickly slides into guide groove one 24 again under the elastic force of spring three 23, and so on.

[0031] An operating method of a heat setting treatment device for producing nylon monofilaments, the operating method is applicable to the above-mentioned heat setting treatment device for producing nylon monofilaments, and the operating method comprises the following steps: S1: The nylon yarn is heated by the heating box 1. After the heating is completed, the nylon yarn is transmitted from the heating box 1 and is assisted by the guide roller 3. The spray mechanism is started and the nylon yarn passing through is sprayed and cooled by the spray mechanism on the water cooling tank 2. S2: After that, the water-cooled nylon thread is dried by the sponge pad 7 on the mounting roller 5, and the air pump 45 is started, and the nylon thread is further dried by the air pump 45 in cooperation with the air blowing pipe 48; S3: After the sponge pad 7 has been used for a period of time, the angle adjustment mechanism drives the installation roller 5 to rotate, so that the new sponge pad 7 can continue to process the nylon thread, and the sponge pad 7 containing moisture will be filtered by the arc-shaped pressing plate 14.

[0032] Working principle: after the nylon thread is heated by the heating box 1, it is transmitted to the water cooling tank 2. The guide rollers 3 provided on both sides of the top of the water cooling tank 2 can assist in guiding the transmission of the nylon thread. When the nylon thread passes through the water cooling tank 2, the spray mechanism above the water cooling tank 2 will spray cold water to the nylon thread passing below. After the cold water wets and cools the nylon thread, it falls into the water cooling tank 2. When the cooled nylon thread passes through the installation roller 5, it will contact the sponge pad 7 on the fixed plate 6. The sponge pad 7 can absorb the moisture on the surface of the nylon thread to achieve rapid drying, effectively avoiding the situation where the quality and performance of the nylon thread are affected by being soaked in water in the water cooling tank 2. When the sponge pad 7 in contact with the nylon thread has a high moisture content after being used for a period of time, the motor 8 is started. 8 drives the worm 9 to rotate, causing the worm wheel 10 to rotate accordingly, and then the installation roller 5 starts to rotate until the new fixing plate 6 on the side away from the heating box 1 rotates to the top, that is, when the new sponge pad 7 contacts the nylon thread, the motor 8 stops rotating to achieve precise adjustment and control of the angle. When the motor 8 is started, the arc pressure plate 14 moves away from the installation roller 5 under the action of the guide component. At the same time, the connecting rod 15 slides along the bracket 13 and compresses the spring 16. The sponge pad 7, which has been pressed out of water by the arc pressure plate 14, rotates to the side away from the heating box 1, and the sponge pad 7 that has absorbed the moisture on the surface of the nylon thread rotates to the position corresponding to the arc pressure plate 14. When the motor 8 stops, the connecting rod 15 is reset under the elastic force of the spring 16, and the arc pressure plate 14 is reset accordingly. , and the sponge pad 7 that has absorbed the moisture on the surface of the nylon thread and rotated here is filtered, and the moisture contained in it is squeezed out, so that the sponge pad 7 can continue to dry the nylon thread after it rotates above the installation roller 5. When the motor 8 drives the worm 9 to rotate, the gear 11 drives the rack 20 to slide, so that the connecting rod 21 cooperates with the fixed sleeve 17 to drive the arc pressure plate 14 away from the installation roller 5. At the same time, the elastic member on the rack 20 slides along the guide groove 1 24 toward the connection between it and the guide groove 2 25 until the motor 8 stops. At this time, the elastic member is located in the guide groove 25. When the arc pressure plate 14 is reset under the elastic force of the spring 16, the elastic member slides in the guide groove 25, the rack 20 does not contact the gear 11, and the connecting rod 21 is disconnected. 9 compresses the spring 2 18 in the fixed sleeve 17 until the elastic member slides out of the guide groove 25. The connecting rod 2 19 drives the rack 20 to mesh with the gear 11 again under the elastic force of the spring 2 18 to achieve reset. This reciprocating process allows the arc pressure plate 14 to not contact and rub against the sponge pad 7 when the installation roller 5 rotates. When the installation roller 5 stops rotating, the arc pressure plate 14 can be reset to filter the sponge pad 7 containing water. When the guide block 22 slides in the guide groove 1 24, the spring 3 23 is in a compressed state until the guide block 22 slides from the guide groove 1 24 to the guide groove 2 25. Because the groove depth of the guide groove 25 is greater than that of the guide groove 1 24, the guide block 22 can quickly fit with the guide groove 2 25 under the elastic force of the spring 3 23.When the guide block 22 slides to the inclined surface in the guide groove 25, the spring 3 23 is compressed again until the guide block 22 slides out of the guide groove 25 and then returns to the guide groove 1 24. Under the elastic force of the spring 3 23, the guide block 22 quickly slides into the guide groove 1 24 again, and so on. When the sponge pad 7 is worn out after long-term use, the worn sponge pad 7 and its corresponding fixing plate 6 can be pulled out by rotating and disassembling the end cover 37, and a new sponge pad 7 and its fixing plate 6 can be slid into the installation groove 35 to achieve quick replacement. After that, the end cover 37 can be removed. The cover 37 is threadedly connected with the thread groove 36 to lock the fixing plate 6. A notch is provided on the end cover 37 to facilitate the staff to remove the end cover 37 from the end of the mounting roller 5 when removing the end cover 37. The cold water at the bottom of the water cooling tank 2 can be pumped into each spray pipe 43 by a water pump 39 in cooperation with a water pumping pipe 40 and a water supply pipe 41. Then, a plurality of nozzles 44 provided on the spray pipe 43 perform surrounding spray cooling on the nylon thread passing through. The sprayed water falls on the filter plate 38 after passing through the nylon thread, and a part of the water is directly filtered by the filter plate 38 and then falls down The water falls into the water cooling tank 2 below the filter plate 38, and the other part of the water flows along the inclined part of the filter plate 38 to flush the impurities attached to the filter plate 38 until the water flow carrying the impurities enters the arc-shaped part, where the accumulation and filtration are completed. At the same time, the impurities will also gather at the arc-shaped part, which is convenient for the staff to carry out centralized treatment regularly. The air pump 45 cooperates with the air supply pipe 46 to supply air to the blowing pipe 1 48 and the blowing pipe 2 50. The blowing pipe 1 48 cooperates with a plurality of nozzles 2 49 to further blow and dry the nylon thread dried by the sponge pad 7. The pipe 2 50 cooperates with several nozzles 3 51 to further dry the sponge pad 7 after filtering by the arc pressure plate 14. The screw sleeve 33 can be driven to slide by rotating the screw rod 34, so that the support plate 32 drives the two limit plates 2 31 to slide, and then the limit plate 1 29, the support rod 28 and the U-shaped frame 4 slide as a whole. It is not only convenient for the staff to adjust the height of the installation roller 5 in time after the sponge pad 7 is worn to a certain extent, but also the height of the installation roller 5 can be adjusted according to the different diameters of the nylon thread to avoid excessive friction between the sponge pad 7 and the nylon thread.
