Description

Technical Field

[0001] This utility model belongs to the field of wool sweater finishing technology, and in particular relates to a wool sweater finishing device. Background Technology

[0002] The finishing processes for wool sweaters encompass multiple dimensions, including basic finishing, appearance finishing, hand feel finishing, and functional finishing. Antistatic finishing, as a crucial aspect of functional finishing, directly impacts the wearing experience and market competitiveness of the product. Currently, common antistatic treatment methods in the industry mainly include impregnation, coating, and spraying. For example, Chinese utility model patent CN220099393U uses a brush to apply an antistatic agent, but this method has significant drawbacks:

[0003] High risk of fraying: When the brush comes into direct contact with the wool fibers, mechanical friction can easily cause the fibers to break or pill, seriously affecting the appearance and quality of the wool sweater.

[0004] Insufficient uniformity: It is difficult to accurately control the amount of antistatic agent applied by manual or mechanical brushes, which can easily lead to localized over-thickness or missed areas, resulting in unstable antistatic performance.

[0005] Poor penetration: Traditional spraying methods rely solely on surface adsorption, making it difficult for antistatic agents to penetrate into the wool fibers, resulting in a general water resistance of less than 10 washes.

[0006] Poor environmental adaptability: Some antistatic agents have reduced moisture absorption capacity in dry environments, resulting in a decrease in antistatic effect and requiring frequent repeated treatment.

[0007] In addition, although some processes have introduced steam assistance, the synergistic effect of steam and antistatic agents has not been achieved, and the problem of wool fibers being easily affected by moisture and deformed after steam treatment has not been solved.

[0008] Therefore, it is essential to invent a finishing device for wool sweaters. Utility Model Content

[0009] To solve the above-mentioned technical problems, this utility model provides a wool sweater finishing device, including a conveyor frame, a conveyor belt, a drive component, a finishing machine cover, a penetration roller, a finishing generator, penetration holes, a guide cover, an exhaust hood, and an exhaust fan. The conveyor belt is mounted on a conveyor roller rotatably mounted on the conveyor frame, and one of the conveyor rollers is fixed to the output end of the drive component fixedly mounted on the conveyor frame. The finishing machine cover is fixedly mounted on the conveyor frame, and the penetration roller and the finishing generator are rotatably mounted on the finishing machine cover. The penetration roller is provided with penetration holes, and the penetration roller and the finishing generator are interconnected. The guide cover and the exhaust hood are fixedly mounted on the finishing machine cover, and the exhaust fan is fixedly mounted on the exhaust hood.

[0010] Preferably, the conveyor belt is located below several transversely distributed permeation rollers, and there is a gap between the permeation rollers and the conveyor belt for the sweater to be conveyed.

[0011] Preferably, the penetrating roller has a hollow roller structure, with one end of the penetrating roller rotatably mounted on the finishing machine cover, and the other end of the penetrating roller connected to the finishing generator.

[0012] Preferably, each of the permeation rollers is provided with a guide cover on its exterior. The guide cover is fixedly installed inside the finishing machine cover, wherein the guide cover is an inverted "U" shaped structure, and the opening of the guide cover faces downward and toward the direction of the conveyor belt.

[0013] Preferably, the finishing generator connected to the permeation roller includes a mixing conveying pipe, a steam generator, an ultrasonic atomizer, spiral blades, and a conveying pipe. One end of the mixing conveying pipe is connected to the steam generator and the ultrasonic atomizer, respectively, and the steam generator and the ultrasonic atomizer are arranged adjacent to each other. The inner wall of the mixing conveying pipe is provided with spiral blades, and a plurality of conveying pipes are rotatably mounted on the mixing conveying pipe. Each conveying pipe rotatably passes into the finishing machine cover and is connected to the corresponding permeation roller.

[0014] Preferably, the mixing and conveying pipe is located outside the finishing machine cover, and the spiral blades on the inner wall of the mixing and conveying pipe allow the flow of steam generated by the steam generator and atomized medicine generated by the ultrasonic atomizer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes a steam generator to produce moist, hot steam that expands the wool scales. This, combined with antistatic agent microdroplets generated by an ultrasonic atomizer, is mixed by spiral blades and then evenly applied to the wool fiber surface through permeation pores. This design allows the antistatic agent molecules to adhere to the fiber surface via hydrogen bonds and van der Waals forces, penetrating to the cortex to form a conductive network and enhancing antistatic performance. The moisture in the steam further enhances the antistatic agent's hygroscopic capacity, forming a continuously conductive water film that ensures stable antistatic effects under varying environmental humidity levels.

[0017] This invention employs a rolling contact steam-atomization treatment to avoid direct friction between the brush and the fibers, reducing snagging and protecting the structural integrity of the wool fibers. The moist heat of the steam softens the wool fibers, and combined with the silicone softener in the antistatic agent, it enhances the softness of the sweater while maintaining its mechanical properties.

[0018] The spiral guide plate on the inner wall of the permeation roller and the spiral blades in the mixing and conveying pipe of this utility model form turbulent mixing, which effectively prevents the antistatic agent droplets from agglomerating and clogging the steam holes, and extends the equipment maintenance cycle.

[0026] As attached Figure 1 To be continued Figure 3 As shown:

[0027] This utility model provides a finishing device for wool sweaters, including a conveyor frame 1, a conveyor belt 2, a drive component 3, a finishing machine cover 4, a penetration roller 5, a finishing generator 6, penetration holes 7, a guide cover 8, an exhaust hood 9, and an exhaust fan 10. The conveyor belt 2 is mounted on a conveyor roller rotatably installed on the conveyor frame 1, and one of the conveyor rollers is fixed to the output end of the drive component 3 fixedly installed on the conveyor frame 1. The finishing machine cover 4 is fixedly installed on the conveyor frame 1, and the penetration roller 5 and the finishing generator 6 are rotatably installed on the finishing machine cover 4. The penetration roller 5 is provided with penetration holes 7, and the penetration roller 5 and the finishing generator 6 are interconnected. The guide cover 8 and the exhaust hood 9 are fixedly installed on the finishing machine cover 4, and the exhaust fan 10 is fixedly installed on the exhaust hood 9.

[0028] Furthermore, the conveyor belt 2 is made of high-temperature resistant rubber and is laterally tensioned and installed on several sets of conveyor rollers on the conveyor frame 1, driven by the drive component 3 (servo motor) to rotate cyclically. Several penetrating rollers 5 are evenly distributed laterally along the direction of wool sweater conveying, and are installed parallel to each other directly above the conveyor belt 2. The distance between them forms a processing channel for the wool sweater (not shown in the figure) to pass through smoothly. This spacing design ensures that the steam and atomized agent discharged from the penetrating rollers 5 can fully act on the surface of the wool sweater, while avoiding direct contact between the rollers and the wool sweater, which could cause fiber damage.

[0029] Furthermore, the penetration roller 5 is a hollow stainless steel roller with a smooth inner wall to reduce reagent residue. One end is rotatably mounted to the side wall of the finishing machine cover 4 via a deep groove ball bearing, and the other end is sealed and connected to the delivery pipe 65 of the finishing generator 6 via a rotary joint, ensuring that steam and atomized reagent are stably input into the roller body under pressure. The penetration holes 7 evenly distributed on the roller surface are arranged in a spiral to ensure uniform output of the treatment agent. The penetration roller 5 can rotate synchronously with the wool sweater conveyor to achieve dynamic and uniform treatment.

[0030] Furthermore, each penetration roller 5 is fitted with an inverted "U"-shaped guide cover 8. This guide cover 8 is made of 304 stainless steel sheet, bent into shape, with an opening width 2-3 cm larger than the outer diameter of the penetration roller 5, and its bottom edge 10-15 cm from the upper surface of the conveyor belt 2. The guide cover 8 is welded and fixed to the inner wall of the finishing machine cover 4 via an L-shaped bracket, guiding the steam and atomized agent discharged from the penetration roller 5 vertically downwards to act on the surface of the sweater, reducing lateral diffusion and heat loss. A guide bevel (30° angle) is provided at the bottom edge of the guide cover 8 to prevent condensate from accumulating and dripping inside the cover.

[0031] Furthermore, the finishing generator 6 includes a horizontally arranged mixing and conveying pipe 61, one end of which is connected to the steam generator 62 and the ultrasonic atomizer 63 via flanges, and the other end is closed. Helical blades 64 are welded to the inner wall of the mixing and conveying pipe 61, with the helical direction aligned with the steam flow direction, forcing the steam and atomized agent to form a helical turbulence within the pipe. Several conveying pipes 65 are evenly distributed along the axial direction of the mixing and conveying pipe 61, and are rotatably connected to the mixing and conveying pipe 61 via rotary joints. Their other ends rotatably pass through sealing holes in the side wall of the finishing machine cover 4 via bearing seats, connecting to the inner cavity of the corresponding permeation roller 5. The conveying pipes 65 can rotate synchronously with the permeation roller 5, and fluororubber sealing rings are used at the connection points to prevent leakage.

[0032] Furthermore, the mixing and conveying pipe 61 is fixed to the support frame (not shown in the figure) on the outside of the finishing machine cover 4 and the conveyor frame 1, at a height of 1.2-1.5m above the ground, facilitating inspection and maintenance. The spiral direction of the spiral blade 64 forms a 45° angle with the axis of the mixing and conveying pipe 61, guiding the humid hot steam generated by the steam generator 62 and the antistatic agent droplets sprayed by the ultrasonic atomizer 63 to fully mix inside the pipe, forming a gas-liquid two-phase flow. The mixing and conveying pipe 61 is made of high-pressure resistant stainless steel, and the inner wall is mirror-polished to reduce the adhesion and residue of the agent.

[0033] The working principle is as follows: First, after the drive component 3 (servo motor) is started, it drives the conveyor roller on the conveyor frame 1 to rotate, so that the high-temperature resistant rubber conveyor belt 2 rotates at a constant speed, and smoothly conveys the sweater (not shown in the figure) to the processing area inside the finishing machine cover 4.

[0034] Secondly, the steam generator 62 in the slurry generator 6 generates humid hot steam at 50-80℃ and 0.1-0.3MPa, while the ultrasonic atomizer 63 atomizes the antistatic agent solution into microdroplets of 1-5μm. The two are forcibly mixed in the mixing and delivery pipe 61 by the spiral blades 64 with a 45° spiral direction, forming a spiral turbulent gas-liquid two-phase flow, ensuring that the steam and antistatic agent droplets are uniformly mixed.

[0035] Subsequently, the mixed treatment agent enters the inner cavity of the hollow permeation roller 5 through the conveying pipe 65 (connected to the mixing conveying pipe 61 via a rotary joint), and is uniformly sprayed out from the spirally arranged permeation holes 7 on the roller surface under steam pressure. The permeation roller 5 rotates synchronously with the wool sweater conveyor at the same speed, realizing the dynamic and continuous output of the treatment agent.

[0036] The ejected steam and atomizing agent are directed vertically downwards onto the surface of the wool sweater by the inverted "U"-shaped guide hood 8: the steam causes the scales of the wool fibers to swell, increasing surface activity and creating conditions for the adsorption of antistatic agents; the atomized antistatic agent adheres to the fiber surface through hydrogen bonds and van der Waals forces and penetrates into the cortex to form a conductive network.

[0037] During the treatment process, the exhaust hood 9 and the exhaust fan 10 form a waste gas treatment system that continuously discharges excess moisture and trace amounts of volatile chemicals from the cleaning machine hood 4 at a wind speed of 5-8 m / s, maintaining stable internal airflow and preventing condensation and chemical residues.

[0038] Finally, the sweater passes through the finishing machine cover 4 driven by the conveyor belt 2, completing the uniform penetration finishing of the steam-assisted antistatic agent, achieving the dual effect of improving the surface antistatic performance and protecting the fiber structure.

[0039] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
