Description

Technical Field

[0001] This utility model relates to the field of textile material surface treatment technology, and in particular to a device for coating the surface of superhydrophobic polyester fibers. Background Technology

[0002] Polyester fiber is widely used in clothing, home textiles, and industrial textiles due to its high strength, good elasticity, and wear resistance. However, polyester fiber itself has a certain degree of hydrophilicity, and its performance is difficult to meet the requirements in some scenarios where hydrophobicity is required, such as outdoor waterproof fabrics and medical stain-resistant textiles.

[0003] To improve the hydrophobicity of polyester fibers, surface coating is often used in the existing technology. However, the current coating devices have many shortcomings. They are not uniform enough when coating polyester fibers, resulting in unstable hydrophobic properties of the fiber surface and reducing the coating effect on polyester fibers. To address the above problems, an improved and upgraded superhydrophobic polyester fiber surface coating device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a superhydrophobic polyester fiber surface coating device to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a superhydrophobic polyester fiber surface coating device, including a processing machine table, a PLC controller fixedly installed on the outer wall of the processing machine table, an unwinding roller fixedly installed on one side of the upper end of the processing machine table and an auxiliary guide roller installed on one side of the unwinding roller, a drying box fixedly installed on the other side of the upper end of the processing machine table and a cooling box installed on one side of the drying box, a circulation structure installed inside the cooling box, and a coating tank and a recycling tank respectively opened on the upper end of the processing machine table; An adjustment structure is provided between the coating tank and the recycling tank. The adjustment structure includes two positioning seats fixedly installed on the upper part of the processing machine table. A drive motor is fixedly installed on the outer wall of one of the positioning seats. The output end of the drive motor is fixedly connected to a coating roller. Both ends of the coating roller are rotatably installed on the two positioning seats. Limit plates are fixedly installed on the inner walls of the positioning seats. Two sets of fixing blocks are fixedly installed on the inner walls of the two limit plates. An adjusting screw is rotatably installed inside one set of fixing blocks. A guide block is threadedly connected to the outer wall of the adjusting screw. A scraper is fixedly installed at one end of the guide block. One end of the scraper is positioned opposite to the coating roller.

[0006] As a preferred embodiment of the above technical solution, the coating roller passes through the interior of two limiting plates at both ends, and a limiting frame is fixedly provided at the upper end of the two limiting plates. A rotating rod is fixedly connected to one end of the adjusting screw, and a groove is opened inside one of the limiting plates, with a scale line fixedly provided at the upper end of the groove.

[0007] As a preferred embodiment of the above technical solution, one end of the guide block is slidably connected to the inside of the groove, and there are two guide blocks in total. Both ends of the other end of the fixed block are fixedly installed with guide slide rods. The outer wall of the guide slide rod is slidably connected with guide blocks, and one end of each of the two guide blocks is fixedly connected to both sides of the outer wall of the scraper.

[0008] As a preferred embodiment of the above technical solution, a channel is fixedly provided between the coating tank and the recycling tank, a take-up roller is fixedly provided on one side of the upper end of the processing machine platform, and a servo motor is fixedly provided at one end of both the take-up roller and the unwind roller.

[0009] As a preferred embodiment of the above technical solution, a cooling fan is fixedly installed inside the cooling box, and the circulation structure includes a circulation fan fixedly installed on the top of the cooling box. A triangular tube is fixedly installed at one end of the circulation fan, and a first connecting pipe and a second connecting pipe are fixedly connected to both ends of the triangular tube, respectively.

[0010] As a preferred embodiment of the above technical solution, the first connecting pipe and the second connecting pipe respectively penetrate the interior of the cooling box and their extended ends are respectively fixedly connected to multiple air inlet pipes and air outlet pipes, and the air inlet pipes and air outlet pipes are adapted to the position of the polyester fibers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device is equipped with an adjustment structure. A drive motor rotates the coating roller clockwise on the positioning seat, causing the roller surface to first immerse itself in the coating tank to pick up the superhydrophobic coating material. A scraper on the other side of the roller first contacts the roller surface, scraping off excess coating material, leaving a uniformly thick coating on the roller surface. As the roller continues to rotate, it reaches the point of contact with the polyester fiber, transferring the uniform coating to the polyester fiber surface to complete the coating process. Excess coating material scraped off by the scraper falls into a recycling tank, which is connected to the coating tank via a pipe, allowing the recycled coating material to flow back into the tank for reuse. Simultaneously, rotating the rotating rod drives the scraper, fixed to the guide block on the adjusting screw, to move precisely along the scale lines, facilitating scraper position adjustment and widening the gap with the coating roller. This allows for coating of different thicknesses, ensuring a uniform coating on the polyester fiber surface and maintaining the stability of the fiber's hydrophobic properties. The recycling tank allows for the recovery and reuse of excess coating material, reducing material waste and lowering production costs.

[0012] 2. The device of this utility model is equipped with a circulation structure. By driving the circulating fan, the cold air inside the cooling box is drawn out along the air inlet pipe and transported to the second connecting pipe through the first connecting pipe. This causes the second connecting pipe to expel the cold air from multiple air outlet pipes, which facilitates the rapid flow of the internal cold air. This speeds up the cooling and shaping efficiency of the polyester fiber and helps to improve the processing efficiency of the polyester fiber.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 5As shown in the figure, this embodiment provides a superhydrophobic polyester fiber surface coating device, including a processing machine 1, a PLC controller 2 fixedly installed on the outer wall of the processing machine 1, an unwinding roller 3 fixedly installed on one side of the upper end of the processing machine 1 and an auxiliary guide roller installed on one side of the unwinding roller 3, a drying box 7 fixedly installed on the other side of the upper end of the processing machine 1 and a cooling box 8 installed on one side of the drying box 7, a circulation structure 9 installed inside the cooling box 8, and a coating tank 4 and a recycling tank 5 respectively opened on the upper end of the processing machine 1; An adjustment structure 6 is provided between the coating tank 4 and the recovery tank 5. The adjustment structure 6 includes two positioning seats 61 fixedly installed on the upper end of the processing machine table 1. A drive motor 62 is fixedly installed on the outer wall of one of the positioning seats 61. A coating roller 63 is fixedly connected to the output end of the drive motor 62. Both ends of the coating roller 63 are rotatably installed on the two positioning seats 61. A limit plate 64 is fixedly installed on the inner wall of each positioning seat 61. Two sets of fixing blocks 66 are fixedly installed on the inner wall of each of the two limit plates 64. An adjustment screw 68 is rotatably installed inside one set of fixing blocks 66. A guide block 69 is threadedly connected to the outer wall of the adjustment screw 68. A scraper 691 is fixedly installed on one end of the guide block 69. One end of the scraper 691 is opposite to the coating roller 63.

[0018] like Figures 3 to 4 As shown, the coating roller 63 passes through the interior of two limiting plates 64 at both ends. A limiting frame 65 is fixedly installed on the upper end of the two limiting plates 64. A rotating rod 67 is fixedly connected to one end of the adjusting screw 68. A groove is opened inside one of the limiting plates 64, and a scale line 693 is fixedly installed on the upper end of the groove. One end of the guide block 69 is slidably connected inside the groove, and there are two guide blocks 69 in total. Guide slide rods 692 are fixedly installed on both ends of the other end of the fixed block 66. Guide blocks 69 are slidably connected to the outer wall of the guide slide rods 692. One end of the two guide blocks 69 is fixedly connected to both sides of the outer wall of the scraper 691. A channel is fixedly provided between the coating tank 4 and the recycling tank 5. A take-up roller 10 is fixedly installed on one side of the upper end of the processing table 1. A servo motor is fixedly installed at one end of both the take-up roller 10 and the unwind roller 3.

[0019] A superhydrophobic coating material is installed in the coating tank 4. The coating roller 63 is partially immersed in the coating material in the coating tank 4. The axis of the coating roller 63 is parallel to the horizontal direction. Polyester fibers pass over the coating roller 63 and contact the surface of the coating roller 63 to pick up the coating material. A scraper 691 is set on one side of the coating roller 63 and contacts the surface of the coating roller 63 to scrape off excess coating material from the surface of the coating roller 63. The gap between the scraper 691 and the coating roller 63 can be adjusted by the adjustment structure 6 to control the coating thickness. A recovery tank 5 is set below the coating roller 63 and the scraper 691 to recover the excess coating material scraped off by the scraper 691. The recovery tank 5 is connected to the coating tank 4 through a pipe so that the recovered coating material can flow back into the coating tank 4 for recycling. At the same time, a tension sensor is set between the unwinding roller 3 and the auxiliary guide roller. Under the detection of the tension sensor, the polyester fibers enter the coating area with a stable tension. The existing technology is mature and widely used. The tension sensor adopts the TRM-1000 series model, which has the characteristic of high-precision tension measurement.

[0020] like Figure 5 As shown, a cooling fan 81 is fixedly installed inside the cooling box 8. The circulation structure 9 includes a circulation fan 91 fixedly installed on the top of the cooling box 8. A triangular tube is fixedly installed at one end of the circulation fan 91, and a first connecting pipe 92 and a second connecting pipe 94 are fixedly connected to both ends of the triangular tube. The first connecting pipe 92 and the second connecting pipe 94 pass through the interior of the cooling box 8, and multiple air inlet pipes 93 and air outlet pipes 95 are fixedly connected to their extended ends. The air inlet pipes 93 and air outlet pipes 95 are adapted to the position of the polyester fibers.

[0021] By setting up a cooling fan 81, the cooling fan 81 in the cooling zone is an axial flow fan model SF-120P, which can quickly reduce the temperature of the cured polyester fiber to room temperature to meet the cooling requirements. At the same time, a circulation structure 9 is set up to facilitate the rapid cooling and shaping of the polyester fiber passing through the cooling box 8, making it easier to wind it up.

[0022] The working principle and process of this utility model are as follows: During operation, the operator installs the polyester fiber roll to be processed onto the unwinding roller 3. Then, by pre-setting parameters for the servo motor, drive motor 62, cooling fan 81, etc., in the PLC controller 2, the polyester fiber sequentially passes through the auxiliary guide roller and enters above the coating roller 63. Then, the external power supply is turned on, and the drive motor 62 drives the coating roller 63 to rotate clockwise on the positioning seat 61. This causes the surface of the coating roller 63 to first immerse itself in the coating tank 4 to pick up the superhydrophobic coating material, and then, as it rotates, it is carried away from the liquid surface. At this time, the positioning seat 61... The scraper 691 on the other side of the coating roller 63 will first contact the surface of the coating roller 63 to scrape off the excess coating material, so that the surface of the coating roller 63 retains a coating of uniform thickness. Then, the surface of the coating roller 63, which has been scraped off by the scraper 691, continues to rotate until it reaches the position in contact with the polyester fiber, and transfers the uniform coating to the surface of the polyester fiber to complete the coating. The excess coating material scraped off by the scraper 691 falls into the recycling tank 5. The recycling tank 5 is connected to the coating tank 4 through a pipe, so that the recycled coating material can flow back into the coating tank 4 for recycling. When a thicker coating needs to be applied to the polyester fiber, the scraper 691, fixed by the guide block 69 on the adjusting screw 68, is precisely moved along the scale line 693 by rotating the rotating rod 67. At the same time, the scraper 691 slides on the guide slide rod 692 using another guide block 69, which facilitates the adjustment of the position of the scraper 691 and widens the gap with the coating roller 63, thus making it suitable for coatings of different thicknesses. The coated polyester fiber enters the curing and drying chamber 7 and then enters the internal ultraviolet curing zone for curing under ultraviolet light. Finally, it passes through the cooling chamber 8 and is continuously cooled by the cooling fan 81. At the same time, the circulating fan 91 drives the cold air inside the cooling chamber 8 to be drawn out through the air inlet pipe 93 and transported through the first connecting pipe 92 to the second connecting pipe 94, causing the second connecting pipe 94 to expel from multiple air outlet pipes 95, which rapidly circulates the internal cold air, thereby accelerating the cooling and shaping efficiency of the polyester fiber. The processed polyester fiber is then wound up by the winding roller 10 driven by the servo motor.
