Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric coating device. Background Art

[0002] During the processing of antistatic non-woven fabrics, non-woven fabrics that do not have antistatic function are often post-treated by coating. An antistatic layer is formed on the surface of the non-woven fabric to improve the antistatic performance of the non-woven fabric.

[0003] The coating materials used for antistatic treatment of non-woven fabrics generally include solvents, dispersants, active ingredients and other components. These components may naturally settle, agglomerate, and delaminate when standing still. This phenomenon will cause uneven distribution of the coating material components and affect the subsequent coating quality. Therefore, the coating material needs to be stirred during the coating process. At present, the stirring mechanism in most existing raw material barrels only stirs the middle area of ​​the raw material barrel. However, for some relatively viscous antistatic coating materials, the stirring mechanism is difficult to directly drive the coating material close to or attached to the side wall of the raw material barrel to stir. In addition, in order to ensure the coating quality and prevent the presence of too much gas in the coating material, the stirring mechanism needs to use low-speed stirring. Therefore, it often takes a long time of stirring to make the coating material evenly stirred, and the stirring efficiency is poor, which is especially true for square raw material barrels.

DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 3 As shown, the utility model discloses a non-woven fabric coating device, including a conveying mechanism 4 and a coating mechanism. Since the conveying mechanism 4 can adopt the existing technology, and the coating mechanism provided by the utility model is compatible with most of the current conveying mechanisms 4, this article does not go into too much detail about the conveying mechanism 4, and can roughly refer to the attached drawings for understanding.

[0024] The coating mechanism includes a discharge box 2 and a raw material tank 1, a discharge head 21 is arranged at the lower end of the discharge box 2, and the discharge head 21 is used to inject material onto the surface of the non-woven fabric; a conveying pipe 3 is arranged between the raw material tank 1 and the discharge box 2, and the conveying pipe 3 can determine whether to install a pump body according to the specific shape and height difference; a stirring mechanism is arranged in the raw material tank 1, and the stirring mechanism includes a rotating shaft 11, a stirring paddle and a power box 12, wherein the power box 12 is used to drive the rotating shaft 11 to rotate at a low speed, and a plurality of stirring paddles are arranged and connected to the outer wall of the rotating shaft 11 at different heights.

[0025] The stirring paddle specifically includes a fixed paddle 13 and a movable paddle 14, wherein the fixed paddle 13 is fixedly arranged on the outer wall of the rotating shaft 11, and the movable paddle 14 is slidably arranged on the fixed paddle 13. In this structure, the movable paddle 14 is used to adjust the overall length of the stirring paddle. An extension mechanism is arranged in the raw material tank 1 for making the movable paddle 14 abut against the side wall of the raw material tank 1.

[0026] The working principle of this structure is as follows: when the rotating shaft 11 is rotating, since the movable paddle 14 is always in contact with the raw material tank 1, the stirring paddle can stir the coating raw material in the raw material tank 1 while scraping off the coating raw material on the side wall of the raw material tank 1 to prevent the formation of solidified coating raw material on the side wall of the raw material tank 1. The movable paddle 14 is slidably set on the fixed paddle 13, so that the stirring mechanism can be compatible with round and square raw material barrels. When the stirring paddle rotates in the square raw material barrel, the movable paddle 14 and the fixed paddle 13 can flexibly change the total length of the stirring paddle so that the end of the movable paddle 14 can be in contact with the side wall of the raw material barrel.

[0027] The specific implementation scheme of the extension mechanism is: one end of the movable paddle 14 is slidably arranged on the fixed paddle 13 and the other end is provided with a scraper 141, the scraper 141 is made of magnetic material, and the extension mechanism includes a magnetic surface 15 fixedly arranged on the side wall of the raw material tank 1.

[0028] The sliding scheme of the movable paddle 14 is as follows: a slide rail 131 is provided on the fixed paddle 13 , the slide rail 131 extends along the length direction of the fixed paddle 13 , a slide seat 132 is provided on the slide rail 131 , and the movable paddle 14 is mounted on the slide seat 132 .

[0029] In order to reduce the resistance that the stirring paddle may encounter during the rotation process, the scraper 141 is formed with a slope 142 on the end away from the rotating shaft 11, and the slope 142 is used to have a rounded corner 143 on the edge that abuts against the side wall of the raw material tank 1; at the same time, the movable paddle 14 is hinged on the sliding seat 132, and a reed 133 is provided between the sliding seat 132 and the movable paddle 14.
