Description

Technical Field

[0001] This utility model relates to the technical field of nylon filament production equipment, specifically a production device for improving the durability of nylon filament. Background Technology

[0002] In current nylon filament production, improving fastness usually relies on soaking and spraying functional additives in the finishing process. However, the corresponding production equipment mostly adopts single-tank soaking or fixed-nozzle spraying structures. When local accumulation occurs in the nylon filaments during transmission, some filaments cannot fully contact the fastness-enhancing additives, resulting in large differences in the fastness of the final products. Moreover, after the additives are sprayed or soaked, the excess additives are directly discharged through the open drainage structure without a recycling and circulation mechanism, which not only increases the cost of raw materials but also creates environmental pressure. Utility Model Content

[0003] This invention provides a production device for improving the fastness of nylon yarn, which has the advantages of improving the uniformity of fastness and increasing the utilization rate of additives, thereby solving the problems of uneven contact and low utilization rate of existing additives.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a production device for improving the durability of nylon filament, comprising a production table and a spraying box disposed on the production table, and further comprising a circulating spraying component, a sweeping spraying component, a traction component, and a nylon filament pre-tensioning component, wherein: The production platform has a through hole in the middle, the spray box is located directly above the through hole, the inside of the spray box has a slip slope, and a leakage hole is provided on one side of the slip slope; The circulating spraying assembly includes a liquid storage tank, a water pump, a main pipe, a telescopic pipe, a spray pipe, and spray nozzles.

[0005] The water pump draws the additives from the storage tank into the main pipe, through the telescopic pipe into the spray nozzle, and finally sprays them onto the nylon filaments from the nozzle. Excess additives drip down the inclined slip slope and then fall back into the storage tank through the drain hole, completing the recycling of the additives, improving the utilization rate of the additives and reducing the cost of use.

[0006] As a preferred technical solution of this utility model, the sweeping and spraying assembly includes an electric telescopic rod, a straight rod, a sliding frame, a connecting plate, and an arc-shaped fixing plate.

[0007] As a preferred technical solution of this utility model, the electric telescopic rod is fixed to the top of the spray box by screws, the sliding frame is fitted with both ends of the spray pipe and is slidably engaged, the arc-shaped fixing plate is fixedly connected to the connecting plate by screws, the connecting plates are symmetrically staggered and rotated, wherein the connecting plate located on the inner side is fixed to the inner wall of the spray box by screws.

[0008] As a preferred technical solution of this utility model, the traction component includes nylon guide wheels symmetrically arranged on both sides of the spray box, and a pulley groove is provided at the same height as the nylon guide wheels. A rotating rod is welded to one side of the pulley groove. The rotating rod is fitted into the side wall of the spray box and rotates in cooperation. The pulley groove is provided in a plurality of places and forms a W-shaped structure with the nylon guide wheels.

[0009] The evenly spaced nozzles cover a large area, and the W-shaped path formed by the nylon filament guide rollers and pulley grooves greatly extends the contact time between the nylon filament and the additives, thus improving the uniformity of the spraying.

The sliding rod passes through both ends of the slide plate and is slidably engaged. A support bearing is fixed on the top surface of the slide plate, and a spring is welded to the bottom surface and nested on the outside of the sliding rod. A pre-tightening roller is fitted between the support bearings and is rotatably engaged.

[0012] Compared with existing technologies, this invention provides a production device for improving the fastness of nylon filaments, which has the following beneficial effects: This invention maintains the nylon filaments in a taut state through a pre-tightening mechanism, preventing them from accumulating during transmission. At the same time, the W-shaped winding path extends the contact time, the equidistant nozzles expand the coverage area, and the arc-shaped sweeping spray design ensures that the nylon filaments fully and evenly contact the fastness-enhancing agent from multiple dimensions, solving the problem of large differences in fastness due to local accumulation in traditional devices.

Example 1

[0016] Please see Figures 1-8 This utility model discloses a production device for improving the durability of nylon yarn, including a production table 1 and a spray box 2 installed on the production table 1, and further including a circulating spray component 3, a sweeping spray component 4, a traction component 5, and a nylon yarn pre-tensioning component 6, wherein: The production platform 1 has a through hole 11 in the middle, and the spray box 2 is located directly above the through hole 11. The inside of the spray box 2 is a slurry slope 21, and a leakage hole 22 is provided on one side of the slurry slope 21. Please refer to the appendix. Figure 4The circulating spraying assembly 3 includes a liquid storage tank 31, a water pump 32, a main pipe 33, a telescopic pipe 34, a spray pipe 35, and a nozzle 36. The liquid storage tank 31 is connected to the water pump 32 through a conduit. The water pump 32 is connected to the main pipe 33 through a conduit. The main pipe 33 is connected to the spray pipe 35 through the telescopic pipe 34. The nozzle 36 is equidistantly arranged on one side of the spray pipe 35. The liquid storage tank 31 is located directly below the leakage hole 22. The main pipe 33 is fixed to the outer wall of the spraying box 2 with bolts.

[0017] The water pump 32 draws the additive from the storage tank 31 into the main pipe 33, through the telescopic pipe 34 into the spray pipe 35, and finally sprays it onto the nylon filament from the nozzle 36. The excess additive drips down the inclined slip slope 21 and then falls back into the storage tank 31 through the leakage hole 22 to complete the recycling of the additive, which improves the utilization rate of the additive and reduces the cost of use.

[0018] Please refer to the appendix. Figure 5 The sweeping and spraying assembly 4 includes an electric telescopic rod 41, a straight rod 42, a sliding frame 43, a connecting plate 44, and an arc-shaped fixing plate 45. One end of the electric telescopic rod 41 is fixed to the straight rod 42 with screws. The sliding frames 43 are welded to both ends of the straight rod 42. The arc-shaped fixing plate 45 is fixed to both ends of the spray pipe 35.

[0019] The electric telescopic rod 41 is fixed to the top of the spray box 2 with screws. The sliding frame 43 fits into both ends of the spray pipe 35 and slides. The arc-shaped fixing plate 45 is fixed to the connecting plate 44 with screws. The connecting plates 44 are symmetrically staggered and rotate. The connecting plate 44 located on the inner side is fixed to the inner wall of the spray box 2 with screws.

[0020] Please refer to the appendix. Figure 6 The traction component 5 includes nylon guide wheels 51 symmetrically arranged on both sides of the spray box 2. A pulley groove 52 is provided at the same height as the nylon guide wheels 51. A rotating rod 53 is welded to one side of the pulley groove 52. The rotating rod 53 is fitted into the side wall of the spray box 2 and rotates in cooperation.

[0021] The equidistantly spaced nozzles 36 cover a large area, and together with the nylon filament guide rollers 51 and pulley grooves 52, the W-shaped path formed by the nylon filaments greatly extends the contact time between the nylon filaments and the additives, thus improving the uniformity of the spraying.

[0022] In this embodiment, the electric telescopic rod 41 reciprocates under the control of an external controller, thereby driving the sliding frame 43 on the straight rod 42 to move up and down. When the sliding frame 43 moves, it applies a force to the spray nozzle 35. When the spray nozzle 35 moves up and down, it rotates around the connection point of the two connecting plates 44, thereby causing the nozzle 36 on it to present an arc-shaped sweeping spray state, which greatly improves the uniformity of the spraying. Example 2

[0023] Based on the above embodiment 1, please refer to the appendix. Figure 7 as well as Figure 8 The nylon filament pretensioning assembly 6 includes two sets of symmetrically arranged support columns 61. The bottom of the support column 61 is fixed to the production table 1 by screws, and the top is fixed with a bearing 62 by bolts. A winding roller 63 is embedded between the bearings 62.

[0024] A groove column 64 is provided between the support columns 61. A sliding rod 65 is symmetrically welded to the inner side of the groove column 64. The sliding rod 65 passes through both ends of the slide plate 66 and is slidably engaged. A support bearing 67 is fixed on the top surface of the slide plate 66. A spring 68 is welded to the bottom surface and is nested on the outside of the sliding rod 65. A pre-tightening roller 69 is fitted between the support bearings 67 and is rotatably engaged.

[0025] In this embodiment, the winding roller 63 is used to limit the running path of the nylon filament, so that an upward pulling force is applied to the pre-tensioning roller 69 in the middle of the nylon filament. The pre-tensioning roller 69 is driven by the support bearings 67 at both ends to pull the slide plate 66. Under the guidance of the slide rod 65, the slide plate 66 moves vertically upward in the groove column 64 and pulls the spring 68. The spring 68 deforms freely to adjust the tension of the nylon filament, so as to avoid the nylon filament from breaking due to excessive tension, and at the same time maintain the tension of the nylon filament to avoid the accumulation of nylon filament during subsequent spraying treatment, which would lead to uneven spraying.

[0026] The working principle and usage process of this utility model are as follows: During production, after the nylon yarn is formed, it enters the finishing agent spraying stage. First, it is pulled around the upper side of the winding roller 63, then around the lower side of the pre-tightening roller 69, and then around the upper side of the winding roller 63 before entering the spray box 2 and being wound into a W shape by the traction component 5. Finally, it extends out through the other side of the spray box 2 to continue the subsequent drying operation. The nylon yarn continues to slide under the action of the external take-up roller. During the nylon filament pre-tensioning stage, the winding roller 63 is used to limit the running path of the nylon filament, so that an upward pulling force is applied to the pre-tensioning roller 69 in the middle of the nylon filament. The pre-tensioning roller 69 is driven by the support bearings 67 at both ends to pull the slide plate 66. Under the guidance of the slide rod 65, the slide plate 66 moves vertically upward in the groove column 64 and pulls the spring 68. The spring 68 freely deforms to adjust the tension of the nylon filament, so as to avoid the nylon filament from breaking due to excessive tension, and at the same time maintain the tension of the nylon filament to avoid accumulation during subsequent spraying treatment, which would lead to uneven spraying. The nylon filament then enters the spray box 2, and a fastness-enhancing agent is added to the storage tank 31. Then, the electric telescopic rod 41 is connected to an external controller and a cyclic logic program is input to start the water pump 32 and the electric telescopic rod 41. The water pump 32 draws the agent into the main pipe 33, through the telescopic pipe 34, and into the spray pipe 35. Finally, the agent is sprayed onto the nylon filament from the nozzle 36. The nozzles 36, which are set at equal intervals, have a large coverage area. Together with the nylon filament guide wheel 51 and the pulley groove 52, the nylon filament forms a W-shaped path, which greatly extends the contact time between the nylon filament and the agent and improves the uniformity of the spraying. During spraying, the electric telescopic rod 41 reciprocates under the control of an external controller, thereby driving the sliding frame 43 on the straight rod 42 to move up and down. When the sliding frame 43 moves, it applies a force to the spray nozzle 35. When the spray nozzle 35 moves up and down, it rotates around the connection point of the two connecting plates 44, thereby causing the nozzle 36 on it to present an arc-shaped sweeping spray state, which further improves the uniformity of spraying. Excess additives sprayed on the surface drip down the inclined slip slope 21 and then fall back into the storage tank 31 through the drain hole 22, thus completing the recycling of the additives, improving the utilization rate of the additives and reducing the cost of use.
