Description

Technical Field

[0001] The utility model relates to the technical field of monofilament production, in particular to a cooling device for monofilaments. Background Technique

[0002] Monofilament production refers to obtaining single filaments with a relatively small number of counts during the production of chemical fibers by using a single-hole spinneret. The characteristics of this production method are thin quality, good transparency and feel. The fineness of the monofilament is thicker than that of a single filament in a multifilament. Its production process includes the fine stream of the original solution extruded through the capillary pores of the spinneret from the melted synthetic resin, which is formed after condensation. During the production of monofilaments, the temperature of the monofilaments ejected from the spinneret is relatively high, and a cooling device is required to cool the monofilaments to avoid affecting the subsequent processing of the monofilaments due to excessive temperature. In the prior art, the cooling device for monofilament production includes a cuboid-shaped cooling water tank filled with cooling water. The cooling roller is arranged in the cooling water tank, and the monofilament flows in the cooling water tank under the guidance of the cooling roller. The cold water in the cooling water tank is used to cool the monofilament during the movement. During the cooling process, the initial temperature of the monofilament is relatively high, and it is easy to break due to external forces. Therefore, the guiding effect of some cooling devices on the monofilament is relatively low, and the situation where the monofilament is unevenly distributed in the cooling water tank is likely to occur, and the cold water cannot be fully utilized.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , this embodiment provides a technical solution: A cooling device for monofilament, including a cooling water tank 1, and the inside of the cooling water tank 1 is filled with cold water to cool the monofilament;

[0020] Cooling water tank 1: Its right end is rotatably connected to a conveying roller 5 through a first rotating shaft to convey the monofilament, enabling the cooled monofilament to leave the cooling water tank 1 in a timely manner, facilitating continuous cooling of the monofilament. At the right end of the upper surface of the cooling water tank 1, a mounting frame 6 is installed. Inside the mounting frame 6, a clamping roller 7 is rotatably connected through a second rotating shaft to clamp and convey the monofilament, facilitating control of the length of the monofilament inside the cooling water tank 1. Inside the cooling water tank 1, adjusting mechanisms 2 are respectively provided. At the ends of the adjusting mechanisms 2, a first guiding roller 3 and a second guiding roller 4 that can move up and down are elastically installed. The first guiding roller 3 and the second guiding roller 4 are spaced apart left and right. The monofilament sequentially bypasses the lower side of the first guiding roller 3 and the upper side of the second guiding roller 4 from left to right, enabling the monofilament to move along a serpentine trajectory inside the cooling water tank 1, increasing the contact time and area between the monofilament and the cold water, making the distribution of the monofilament inside the cooling water tank 1 more uniform, and making full use of the cold water. On the outer side of the cooling water tank 1, a single-chip microcomputer 8 and a conveying motor 12 are respectively provided. The output shaft of the conveying motor 12 is fixedly connected to the first rotating shaft of the conveying roller 5 to provide power for the rotation of the conveying roller 5. The input end of the single-chip microcomputer 8 is electrically connected to an external power source to control the start and stop of the overall device. The input end of the conveying motor 12 is electrically connected to the output end of the single-chip microcomputer 8. The adjusting mechanism 2 includes a rotating frame 21, a cross plate 22, a guiding column 23, and a spring 24. The cross plate 22 is respectively vertically slidably connected inside the cooling water tank 1. Inside the sliding holes on the surface of the cross plate 22, guiding columns 23 are vertically slidably connected. Between the ends of the guiding columns 23 on the surface of the same cross plate 22, a rotating frame 21 is provided. Between the rotating frame 21 and the cross plate 22, springs 24 are respectively provided. The springs 24 are respectively movably sleeved on the outer arc surface of the guiding column 23. The first guiding roller 3 and the second guiding roller 4 are respectively rotatably connected to the inside of the rotating frame 21 through a third rotating shaft. During use, the monofilament will exert a force on the first guiding roller 3 and the second guiding roller 4, overcoming the elastic force of the spring 24 and pushing the guiding column 23 to slide relative to the cross plate 22. The elastic force of the spring 24 is used to judge the force exerted by the monofilament. The adjusting mechanism 2 further includes an electric push rod 25, a ranging sensor 26, and a contact sensor 27. The electric push rods 25 are respectively arranged on the front and rear inner walls of the cooling water tank 1. The end of the telescopic end of the electric push rod 25 is respectively fixedly connected to the adjacent cross plate 22 to provide power for the up and down movement of the first guiding roller 3 and the second guiding roller 4. The ranging sensor 26 and the contact sensor 27 are respectively arranged on the lower surface of the cross plate 22. The ranging sensor 26 is used to detect the telescopic amplitude of the spring 24, and whether the contact sensor 27 is in contact with the rotating frame 21 is used to judge whether the force exerted by the monofilament is too large. The input end of the electric push rod 25 is electrically connected to the output end of the single-chip microcomputer 8. The output ends of the ranging sensor 26 and the contact sensor 27 are electrically connected to the input end of the single-chip microcomputer 8. The mounting frame 6 includes a support frame 61, guiding columns 62, and a tension spring 63. The guiding columns 62 are respectively vertically slidably connected inside the sliding holes at the right end of the upper surface of the cooling water tank 1. Between the upper ends of the two guiding columns 62, a support frame 61 is provided.A tension spring 63 is respectively arranged between the support frame 61 and the upper surface of the cooling water tank 1. The tension spring 63 is movably sleeved on the outer arc surface of the guiding pillar 62. The clamping roller 7 is rotationally connected to the inside of the support frame 61 through the second rotating shaft. Under the elastic force of the tension spring 63, the support frame 61 drives the clamping roller 7 to move downward, pressing the single wire against the outer arc surface of the conveying roller 5. Through the relative rotation of the clamping roller 7 and the conveying roller 5, the single wire is conveyed. A handle 9 is arranged on the upper surface of the support frame 61, which is convenient for lifting the support frame 61. Thread grooves 10 are respectively arranged on the outer arc surfaces of the first guiding roller 3, the second guiding roller 4 and the conveying roller 5. Rubber rings 11 are respectively arranged on the outer arc surface of the clamping roller 7, making the conveying track of the single wire more accurate and avoiding the mutual entanglement between single wires.,

[0021] The working principle of a cooling device for single wires provided by the present utility model is as follows: During the production process of single wires, after the single wires leave the nozzle, they enter the cold water in the cooling water tank 1 to cool the single wires. During the cooling process, the single wires sequentially bypass the lower side of the first guiding roller 3 and the upper side of the second guiding roller 4 from left to right, making the single wires move along a serpentine track inside the cooling water tank 1, increasing the contact time and area between the single wires and the cold water, making the distribution of the single wires inside the cooling water tank 1 more uniform, and making full use of the cold water. Then, under the elastic force of the tension spring 63, the support frame 61 drives the clamping roller 7 to move downward, pressing the single wire into the thread groove 10 on the outer arc surface of the conveying roller 5 by using the rubber ring 11. The conveying motor 12 is started through the single-chip microcomputer 8. The output shaft of the conveying motor 12 drives the conveying roller 5 to rotate. Through the relative rotation of the conveying roller 5 and the clamping roller 7, the cooled single wires are conveyed to the right, realizing the continuous production of single wires. At the same time, during the use process, the single wires apply a force to the first guiding roller 3 and the second guiding roller 4, overcoming the elastic force of the spring 24, pushing the guiding column 23 to slide relative to the cross plate 22, and using the distance measuring sensor 26 to detect the amplitude of the expansion and contraction of the spring 24, judging the magnitude of the guiding force received by the single wires. When the force is too large, the rotation speed of the conveying roller 5 is slowed down, making the conveying speed of the single wires less than the ejection speed of the single wires, increasing the length of the single wires in the cooling water tank 1, reducing the force received by the single wires, and avoiding the situation that the single wires are broken due to excessive force.

[0022] It should be noted that the single-chip microcomputer 8 disclosed in the above embodiments can be a PIC16F1823-I / P model single-chip microcomputer, and the conveying motor 12, the electric push rod 25, the ranging sensor 26, and the contact sensor 27 can be freely configured according to the actual application scenario.
