Description

Technical Field

[0001] This invention relates to the field of antistatic treatment technology for wool sweaters, and more particularly to a coating apparatus for an antistatic finishing liquid for wool sweaters. Background Technology

[0002] Wool sweaters occupy an important position in the textile and apparel industry due to their soft touch, excellent warmth retention, and good breathability, and are widely favored by consumers.

[0003] Wool fibers themselves have high insulation properties, but they are prone to generating static electricity due to friction during wearing and processing. This can not only cause wool sweaters to attract dust and become tangled around the skin, affecting the wearing experience and appearance, but may also trigger electrostatic discharge under certain conditions, posing a potential risk. Therefore, antistatic finishing of wool sweaters is a key process in their production and processing.

[0004] Existing antistatic finishing liquid coating devices for wool sweaters, while capable of coating the finishing liquid, suffer from poor coating uniformity. Most devices employ a single spray or single coating roller structure, allowing only one-sided liquid supply during spraying. The fit between the coating roller and the wool sweater cannot be flexibly adjusted according to fabric specifications, easily leading to localized over-coating or under-coating issues. Furthermore, the finishing liquid utilization rate is low, lacking an efficient recycling mechanism; excess finishing liquid is directly discharged or lost, increasing production costs and creating an environmental burden. The drying process after coating also suffers from insufficient adaptability; drying components often use fixed wind speeds and heating power, resulting in uneven hot air distribution and low drying and curing efficiency of the finishing liquid. Uneven drying can also affect the adhesion stability of the antistatic coating. In addition, existing devices have poor overall adaptability, failing to meet the processing needs of wool sweaters of different thicknesses and sizes. The connection between coating and drying processes is also insufficient, easily leading to conveyor jams or excessively long process intervals, hindering production efficiency. Therefore, a coating device for antistatic finishing liquid in wool sweaters is proposed to address these problems. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a coating device for antistatic finishing liquid for wool sweaters, aiming to solve the problems of poor coating uniformity, low utilization rate of finishing liquid, insufficient drying efficiency and adhesion stability, poor adaptability and discontinuous process connection in the prior art, which restrict production efficiency and increase production costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coating device for antistatic finishing liquid of wool sweaters, comprising a device body, a liquid collection tank is provided on one side of the bottom of the inner surface of the device body, a mesh chain conveyor is fixedly connected to the inner wall of the liquid collection tank, a crawler conveyor is fixedly connected to the other side of the bottom of the inner surface of the device body, a drying component is provided on the top of the inner surface of the device body and on the side close to the crawler conveyor, and an adjusting coating component is provided between the device body and the liquid collection tank; The adjustable coating assembly includes an electric lifting frame and a liquid storage tank. The top of the electric lifting frame is fixedly connected to the top of the inner surface of the main body of the device. A coating roller, a sprayer, and an electric extrusion roller are sequentially fixedly connected to the inner side of the electric lifting frame. A nozzle is fixedly connected to the outer wall of the sprayer. A liquid supply diversion pipe is fixedly connected to the top of the sprayer. The outer wall of the liquid storage tank is fixedly connected to the outer surface of the main body of the device. A liquid addition pipe and a liquid supply pump connection pipe are sequentially fixedly connected to the top of the liquid storage tank. A filter core plate is embedded and movably snapped into the top of the liquid storage tank. A recovery pump connection pipe and a sewage discharge pipe are sequentially fixedly connected to the bottom of the liquid storage tank.

[0007] As a further description of the above technical solution: Multiple coating rollers and sprayers are provided, and the multiple coating rollers and sprayers are arranged in an alternating manner.

[0008] As a further description of the above technical solution: The spray nozzles are provided in two sets, and the two sets of spray nozzles are mirror images of each other along the central axis of the sprayer, and each set of spray nozzles has multiple nozzles evenly distributed along the length direction.

[0009] As a further description of the above technical solution: One end of the recovery pump connector is connected to the bottom of the storage tank, and the other end of the recovery pump connector is connected to the inner wall of the collection tank.

[0010] As a further description of the above technical solution: One end of the liquid supply pump connector extends through into the interior of the liquid storage tank, and the other end of the liquid supply pump connector is fixedly connected to the top of the liquid supply diversion pipe.

[0011] As a further description of the above technical solution: The drying assembly includes a blower, the outer wall of which is fixedly connected to the upper surface of the main body of the device, and a hot air box is fixedly connected to the bottom end of the blower. The outer wall of the hot air box is fixedly connected to the inner wall of the main body of the device.

[0012] As a further description of the above technical solution: The inner wall of the hot air box is fixedly connected with an electric heating tube, and the bottom of the hot air box is fixedly connected with an air outlet mesh.

[0013] The present invention has the following beneficial effects: 1. In this invention, by adjusting the electric lifting frame of the coating assembly, different specifications of wool sweaters can be adapted. With the help of staggered sprayers combined with the nozzles on both sides and the coating roller, the finishing liquid is sprayed evenly and coated multiple times. The electric extrusion rollers ensure that the finishing liquid is fully adhered. At the same time, the mesh structure of the mesh conveyor allows excess finishing liquid to leak into the collection tank, and then return to the storage tank through the recycling pump. After being filtered by the filter core plate, it is recycled. This not only improves the coating uniformity but also saves finishing liquid, adapting to the antistatic treatment needs of various wool sweaters.

[0014] 2. In this invention, the coated wool sweater is stably conveyed by the conveyor belt at the discharge end of the main body of the device. In conjunction with the drying component above it, the blower sends air to the hot air box. After the air is heated by the electric heating tubes in the hot air box, the hot air is blown evenly onto the wool sweater by the air outlet net, so as to achieve rapid and uniform drying of the antistatic finishing liquid. This not only ensures the continuity of wool sweater conveying, but also improves the drying efficiency and the stability of finishing liquid adhesion, and helps to efficiently finish the coating process.
