Description

Technical Field

[0001] The present invention belongs to the technical field of heat setting machines, and specifically relates to a heat setting treatment device for nylon monofilament production and its operation method. Background Art

[0002] As a polymer material with high strength, wear resistance, and good mechanical properties, nylon filaments are widely used in fields such as textiles, automobiles, and machinery. Heat setting treatment is an important link in nylon filament processing, aiming to fix its shape and size by heating and maintaining for a certain period of time. When performing heat setting treatment on nylon filaments, a heat setting machine is generally used. A heat setting machine generally consists of a heating device, a transmission device, a cooling device, etc. After the nylon filaments are heated by the heating device, they are led out by the transmission device and quickly cooled and shaped by the cooling device. Currently, most of the cooling devices on heat setting machines are divided into two structures: water cooling and air cooling. The water cooling structure is more favored because of its faster cooling speed and lower input cost.

[0003] In the prior art, most of the water cooling structures on heat setting machines are water cooling tanks. After the nylon filaments are heated and led out, they directly enter the cold water in the water cooling tank to complete rapid cooling. However, the nylon filaments will be in a wet state after passing through the water cooling tank, and this wet state will affect the subsequent processing and use of the nylon filaments, thereby affecting the quality and performance of the nylon filaments. In addition, after the water cooling tank is used for a period of time, impurities usually float on the surface, which causes the nylon filaments to be attached by the impurities floating on the water surface when being led out of the water cooling tank, and requires workers to clean them again, greatly wasting time and energy.

[0004] Therefore, the present invention provides a heat setting treatment device for nylon monofilament production and its operation method. Summary of the Invention

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] Such as Figures 1-11As shown in the figure, a heat setting treatment device for nylon monofilament production according to an embodiment of the present invention includes a heating box 1. A water cooling tank 2 is provided on one side of the heating box 1. Guide rollers 3 are provided at the top of both sides of the water cooling tank 2. A U-shaped frame 4 is provided at the top of the side of the water cooling tank 2 away from the heating box 1. An installation roller 5 is rotatably connected to the U-shaped frame 4. A plurality of fixing plates 6 are detachably connected to the installation roller 5. Sponge pads 7 are uniformly fixed on the fixing plates 6. An angle adjustment mechanism is provided on the U-shaped frame 4, and the angle adjustment mechanism controls the rotation angle of the installation roller 5. A spraying mechanism is provided at the top of the side of the water cooling tank 2 close to the heating box 1. During operation, when the nylon filament is heated by the heating box 1 and then transmitted to the water cooling tank 2, the guide rollers 3 provided at the top of both sides of the water cooling tank 2 can assist in guiding the transmission of the nylon filament. When the nylon filament passes through the water cooling tank 2, the spraying mechanism above the water cooling tank 2 will spray cold water onto the nylon filament passing below. After the cold water wets and cools the nylon filament, it falls into the water cooling tank 2. When the cooled nylon filament passes through the installation roller 5, it will contact the sponge pad 7 on the fixing plate 6. The sponge pad 7 can absorb the moisture on the surface of the nylon filament to achieve rapid drying treatment, effectively avoiding the situation that the quality and performance of the nylon filament are affected after being soaked in water in the water cooling tank 2. When the water content of the sponge pad 7 in contact with the nylon filament is relatively high after being used for a period of time, the angle adjustment mechanism can be used to drive the installation roller 5 to rotate, so that the fixing plate 6 that has not contacted the nylon filament rotates to the upper side, so that a new sponge pad 7 can continue to dry the nylon filament, preventing the water absorption effect from decreasing after using one sponge pad 7 for a long time. By installing the spraying mechanism above the water cooling tank 2, it is possible to prevent the nylon filament from contacting impurities floating in the water cooling tank 2 and at the same time achieve the flushing of the nylon filament.

[0037] The angle adjustment mechanism includes a motor 8, a worm 9 and a worm gear 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 with the worm 9. One end of the installation roller 5 is fixedly connected with the worm gear 10. The worm gear 10 is in transmission connection with the worm 9. During operation, when the angle of the installation roller 5 needs to be adjusted, the motor 8 is started. The worm 9 is driven to rotate by the output shaft of the motor 8, so that the worm gear 10 rotates 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 upper side, that is, when the new sponge pad 7 contacts the nylon filament, the motor 8 stops rotating, realizing precise adjustment and control of the angle.

[0038] 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.

[0039] The guiding component includes a fixed sleeve 17 and a rack 20. A fixed sleeve 17 is fixedly connected to the first connecting rod 15 on one side of the motor 8. A gear 11 is fixedly connected to the end of the worm 9 away from the motor 8. A rack 20 is meshed and connected to one side of the gear 11. A second connecting rod 19 is fixedly connected to the end of the rack 20. The end of the second connecting rod 19 away from the rack 20 extends into the inner cavity of the fixed sleeve 17 and is fixedly connected to a second spring 18. The end of the second spring 18 away from the second connecting rod 19 is fixedly connected to the inner wall of the fixed sleeve 17. The end of the second connecting rod 19 away from the rack 20 is slidably connected to the inner cavity of the fixed sleeve 17. An elastic member is provided at the top of the rack 20. A first guiding groove 24 and a second guiding groove 25 are formed at the bottom of the special-shaped plate 12 on one side of the motor 8. The first guiding groove 24 communicates with the second guiding groove 25. The first guiding groove 24 is parallel to the rack 20. The included angle between the second guiding groove 25 and the first guiding groove 24 is an acute angle. The elastic member is slidably connected to both the first guiding groove 24 and the second guiding groove 25. During operation, while the motor 8 drives the worm 9 to rotate, the gear 11 drives the rack 20 to slide accordingly, causing the second connecting rod 19 to cooperate with the fixed sleeve 17 to drive the arc-shaped pressing plate 14 away from the mounting roller 5. At the same time, the elastic member on the rack 20 slides along the first guiding groove 24 towards the connection part between it and the second guiding groove 25 until the motor 8 stops. At this time, the elastic member is located in the second guiding groove 25. When the arc-shaped pressing plate 14 resets under the elastic force of the first spring 16, the elastic member slides in the second guiding groove 25, and the rack 20 is not in contact with the gear 11. The second connecting rod 19 compresses the second spring 18 in the fixed sleeve 17 until the elastic member slides out of the second guiding groove 25. Then, the second connecting rod 19 drives the rack 20 to mesh with the gear 11 again under the elastic force of the second spring 18 to achieve reset. This process repeats, so that when the mounting roller 5 rotates, the arc-shaped pressing plate 14 does not contact and rub against the sponge pad 7. After the mounting roller 5 stops rotating, the arc-shaped pressing plate 14 can reset to press-filter the water-containing sponge pad 7.

[0040] The elastic member includes a guiding sleeve 21 and a guiding block 22. The guiding sleeve 21 is fixedly connected to the top of the rack 20. A guiding block 22 is slidably connected in the inner cavity of the guiding sleeve 21. A third spring 23 is fixedly connected between the guiding block 22 and the inner wall of the guiding sleeve 21. The top end of the guiding block 22 extends to the outside of the guiding sleeve 21. The guiding block 22 is adapted to the first guiding groove 24 and the second guiding groove 25. The groove depth of the first guiding groove 24 is less than that of the second guiding groove 25. An inclined surface is provided on one side of the second guiding groove 25 away from the first guiding groove 24. During operation, when the guiding block 22 slides in the first guiding groove 24, the third spring 23 is in a compressed state until the guiding block 22 slides from the first guiding groove 24 into the second guiding groove 25. Also, because the groove depth of the second guiding groove 25 is greater than that of the first guiding groove 24, the guiding block 22 can quickly fit with the second guiding groove 25 under the elastic force of the third spring 23. When the guiding block 22 slides to the inclined surface in the second guiding groove 25, the third spring 23 is compressed again until the guiding block 22 slides out of the second guiding groove 25 and then slides back to the first guiding groove 24 for reset. At this time, the guiding block 22 quickly slides into the first guiding groove 24 again under the elastic force of the third spring 23, and so on.

[0041] A plurality of mounting grooves 35 are evenly arranged on the mounting roller 5. Each mounting groove 35 is composed of an arc-shaped groove and a T-shaped groove. The fixing plate 6 is adapted to the mounting groove 35. A threaded groove 36 is formed at one end of the mounting roller 5 away from the motor 8. A end cap 37 is threadedly connected in the threaded groove 36. The end cap 37 is in contact with the fixing plate 6. A notch is provided on the end cap 37. During operation, when the sponge pad 7 is worn after long-term use, the worn sponge pad 7 and its corresponding fixing plate 6 can be pulled out by rotating and removing the end cap 37, and a new sponge pad 7 and its fixing plate 6 can be slid into the mounting groove 35 to achieve quick replacement. Then, the end cap 37 is threadedly connected to the threaded groove 36 to lock the fixing plate 6. By providing a notch on the end cap 37, it is convenient for the staff to move the end cap 37 out of the end of the mounting roller 5 when disassembling the end cap 37.

[0042] The spraying mechanism includes a filter plate 38, a water pump 39 and a spray pipe 43. The filter plate 38 is fixedly connected inside the water cooling tank 2. The filter plate 38 is composed of an inclined part and an arc part. A first mounting frame 42 is fixedly connected to the top of one side of the water cooling tank 2. A plurality of spray pipes 43 are fixedly connected to the first mounting frame 42. A water pump 39 is fixedly installed on the outer wall of the side of the water cooling tank 2 away from the first mounting frame 42. A water suction pipe 40 and a water supply pipe 41 are fixedly connected to the water pump 39. One end of the water suction pipe 40 away from the water pump 39 communicates with the bottom of the inner cavity of the water cooling tank 2. One end of the water supply pipe 41 away from the water pump 39 communicates with a plurality of spray pipes 43. A first nozzle 44 is evenly fixedly connected to the spray pipe 43. The first nozzle 44 is in the shape of a jue. During operation, the water pump 39 cooperates with the water suction pipe 40 and the water supply pipe 41 to pump the cold water at the bottom of the water cooling tank 2 into each spray pipe 43, and then the first nozzle 44 provided on the spray pipe 43 sprays and cools the passing nylon filaments in a surrounding manner. The sprayed water falls onto the filter plate 38 after passing through the nylon filaments. Part of the water directly falls into the water cooling tank 2 below the filter plate 38 after being filtered by the filter plate 38, and the other part of the water flows along the inclined part of the filter plate 38, which can wash the impurities attached to the filter plate 38. Until the water flow carrying impurities enters the arc part, it will accumulate and be filtered here. At the same time, the impurities will also gather at the arc part, which is convenient for the staff to carry out centralized treatment regularly.

[0043] On the side of the mounting roller 5 away from the arc-shaped pressing plate 14, there is a first air blowing pipe 48 and a second air blowing pipe 50. A second mounting frame 47 is fixedly connected to the top of the water cooling tank 2. The second mounting frame 47 is fixedly connected to both the first air blowing pipe 48 and the second air blowing pipe 50. An air pump 45 is fixedly installed on the side of the water cooling tank 2 away from the second mounting frame 47. An air supply pipe 46 is fixedly connected to the air pump 45. One end of the air supply pipe 46 away from the air pump 45 communicates with both the first air blowing pipe 48 and the second air blowing pipe 50. There are two air outlets at one end of the air supply pipe 46 away from the air pump 45. A second nozzle 49 is evenly fixedly connected to the first air blowing pipe 48. The second nozzle 49 is in the shape of a jue. A third nozzle 51 is evenly fixedly connected to the second air blowing pipe 50. The third nozzle 51 inclines towards the mounting roller 5. During operation, the air pump 45 cooperates with the air supply pipe 46 to supply air to the first air blowing pipe 48 and the second air blowing pipe 50. The first air blowing pipe 48 cooperates with a number of second nozzles 49 to further blow and dry the nylon filaments dried by the sponge pad 7. The second air blowing pipe 50 cooperates with a number of third nozzles 51 to further dry the sponge pad 7 after being press-filtered by the arc-shaped pressing plate 14.

[0044] On both sides of the top of the water-cooling tank 2, leg sleeves 26 are fixedly connected. The two leg sleeves 26 are respectively located on both sides of the bottom of the U-shaped frame 4. A cross beam 27 is fixedly connected between the tops of the two leg sleeves 26. A screw rod 34 is rotatably connected to the center of the cross beam 27. A group of support rods 28 are fixedly connected to both sides of the bottom of the U-shaped frame 4. The bottom ends of the support rods 28 extend into the inner cavity of the leg sleeves 26. A first limiting plate 29 and a second limiting plate 31 are slidably connected in the inner cavity of the leg sleeve 26. The first limiting plate 29 is fixedly connected to the support rod 28. The second limiting plate 31 is slidably connected to the support rod 28. A fourth spring 30 is fixedly connected between the first limiting plate 29 and the second limiting plate 31. A nut 33 is threadedly connected to the screw rod 34. A support plate 32 is fixedly connected to the outside of the nut 33. The two sides of the support plate 32 respectively extend into the two leg sleeves 26 and are fixedly connected to the two second limiting plates 31. During operation, by rotating the screw rod 34, the nut 33 can be driven to slide, so that the support plate 32 drives the two second limiting plates 31 to slide, and then the first limiting plate 29, the support rod 28 and the U-shaped frame 4 slide as a whole. This not only facilitates the staff to timely raise the height of the installation roller 5 after the sponge pad 7 is worn to a certain extent, but also can adjust the height of the installation roller 5 according to the different diameters of the nylon filaments, avoiding excessive friction of the sponge pad 7 on the nylon filaments.

[0045] An operation method of a heat setting treatment device for nylon monofilament production, which is applicable to the above-mentioned heat setting treatment device for nylon monofilament production. The operation method includes the following steps:

[0046] S1: The nylon filaments are heated by the heating box 1. After the heating is completed, the nylon filaments are transmitted out of the heating box 1 and are assisted by the guiding roller 3 for transmission. The spraying mechanism is started, and the nylon filaments passing by are sprayed and cooled by the spraying mechanism on the water-cooling tank 2.

[0047] S2: Then, the water-cooled nylon filaments are dried by the sponge pad 7 on the installation roller 5, and the air pump 45 is started. The air pump 45 cooperates with the first air blowing pipe 48 to further dry the nylon filaments.

[0048] S3: After the sponge pad 7 is used for a period of time, the installation roller 5 is driven to rotate by the angle adjustment mechanism, so that the new sponge pad 7 can continue to process the nylon filaments, and the sponge pad 7 containing moisture will be pressed and filtered by the arc-shaped pressing plate 14.

[0049] Working principle: When the nylon wire is heated by the heating box 1 and then 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 wire. When the nylon wire passes through the water cooling tank 2, the spraying mechanism above the water cooling tank 2 sprays cold water onto the nylon wire passing below. After the cold water wets and cools the nylon wire, it falls into the water cooling tank 2. When the cooled nylon wire passes through the installation roller 5, it will contact the sponge pad 7 on the fixing plate 6. Through the sponge pad 7, the moisture on the surface of the nylon wire can be absorbed to achieve rapid drying treatment, effectively avoiding the situation where the quality and performance of the nylon wire are affected after being soaked in water in the water cooling tank 2. When the water content of the sponge pad 7 in contact with the nylon wire is relatively high after being used for a period of time, the motor 8 is started. The motor 8 drives the worm 9 to rotate, causing the worm gear 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 wire, the motor 8 stops rotating, realizing precise angle adjustment control. When the motor 8 is started, the arc-shaped pressing plate 14 moves away from the installation roller 5 under the action of the guiding component. At the same time, the connecting rod 15 slides along the bracket 13 and compresses the first spring 16. The sponge pad 7 that has been pressed out of moisture by the arc-shaped pressing 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 wire rotates to the position corresponding to the arc-shaped pressing plate 14. When the motor 8 stops, the connecting rod 15 is reset under the elastic force of the first spring 16, and the arc-shaped pressing plate 14 is reset accordingly, and presses and filters the sponge pad 7 that has absorbed the moisture on the surface of the nylon wire that has rotated here, squeezing out the moisture contained in it, so that the sponge pad 7 can continue to dry the nylon wire after rotating above the installation roller 5. While the motor 8 drives the worm 9 to rotate, the gear 11 drives the rack 20 to slide accordingly, causing the connecting rod 19 to cooperate with the fixed sleeve 17 to drive the arc-shaped pressing plate 14 away from the installation roller 5. At the same time, the elastic member on the rack 20 slides along the first guiding groove 24 towards the connection with the second guiding groove 25 until the motor 8 stops. At this time, the elastic member is located in the second guiding groove 25. When the arc-shaped pressing plate 14 is reset under the elastic force of the first spring 16, the elastic member slides in the second guiding groove 25, and the rack 20 does not contact the gear 11. The connecting rod 19 compresses the second spring 18 in the fixed sleeve 17 until the elastic member slides out of the second guiding groove 25, and the connecting rod 19 drives the rack 20 to mesh with the gear 11 again under the elastic force of the second spring 18, realizing reset. In this way, when the installation roller 5 rotates, the arc-shaped pressing plate 14 does not contact and rub against the sponge pad 7. When the installation roller 5 stops rotating, the arc-shaped pressing plate 14 can be reset to press and filter the water-containing sponge pad 7. When the guiding block 22 slides in the first guiding groove 24, the third spring 23 is in a compressed state until the guiding block 22 slides from the first guiding groove 24 to the second guiding groove 25. Also, because the groove depth of the second guiding groove 25 is greater than that of the first guiding groove 24, the guiding block 22 can quickly fit with the second guiding groove 25 under the elastic force of the third spring 23.When the guiding block 22 slides to the inclined surface in the second guiding groove 25, the third spring 23 is compressed again. Until after the guiding block 22 slides out of the second guiding groove 25 and then resets and slides to the first guiding groove 24, the guiding block 22 quickly slides into the first guiding groove 24 again under the elastic force of the third spring 23. This process repeats. When the sponge pad 7 is worn after long-term use, by rotating and removing the end cover 37, the worn sponge pad 7 and its corresponding fixing plate 6 can be taken out, 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 is threadedly connected to the threaded groove 36 to lock the fixing plate 6. By providing a notch on the end cover 37, it is convenient for the staff to remove the end cover 37 from the end of the installation roller 5 when disassembling the end cover 37. Through the water pump 39 cooperating with the water suction pipe 40 and the water supply pipe 41, the cold water at the bottom of the water cooling tank 2 can be pumped into each spray pipe 43, and then the nylon wire passing through is spray-cooled in a surrounding manner by a number of first nozzles 44 provided on the spray pipe 43. The water sprayed falls onto the filter plate 38 after passing through the nylon wire. Part of the water directly falls into the water cooling tank 2 below the filter plate 38 after being filtered by the filter plate 38, and the other part of the water flows along the inclined part of the filter plate 38, which can wash away the impurities attached to the filter plate 38. Until the water flow carrying impurities enters the arc part, accumulation and filtration will be completed here. At the same time, the impurities will also gather at the arc part, which is convenient for the staff to conduct centralized treatment regularly. Through the air pump 45 cooperating with the air supply pipe 46, air can be sent to the first blowing pipe 48 and the second blowing pipe 50. The first blowing pipe 48 cooperating with a number of second nozzles 49 can further blow and dry the nylon wire dried by the sponge pad 7, and the second blowing pipe 50 cooperating with a number of third nozzles 51 can further dry the sponge pad 7 after being press-filtered by the arc-shaped pressing plate 14. By rotating the screw 34, the nut sleeve 33 can be driven to slide, so that the support plate 32 drives the two second limiting plates 31 to slide, and then the first limiting plate 29, the support rod 28 and the U-shaped frame 4 slide as a whole. This not only facilitates the staff to timely raise the height of the installation roller 5 when the sponge pad 7 is worn to a certain extent, but also can adjust the height of the installation roller 5 according to the different diameters of the nylon wire to avoid excessive friction of the sponge pad 7 on the nylon wire.
