Description

Technical Field

[0001] The utility model relates to the technical field of conductive cloth processing equipment, in particular to an anti-penetration processing device for conductive cloth. Background Art

[0002] Conductive fabric, a conductive fiber fabric with metallic properties, is widely used as an electromagnetic shielding material in electronic devices. However, traditional conductive fabrics have low strength and poor aging resistance. They are prone to breakage and severe aging over time, resulting in a short service life. Furthermore, conductive fabrics generally lack water-resistance. When exposed to water, moisture easily penetrates the other side of the fabric, contaminating electronic components and potentially causing short circuits. Therefore, to improve the performance of conductive fabrics, especially their water-resistance, they are typically coated after production. This involves applying a layer of specialized glue, paint, or ink.

[0003] Existing coating machines, such as the Chinese utility model patent with authorization announcement number CN219291832U, discloses a coating device for conductive cloth processing. The device sprays paint onto the outer walls of the auxiliary coating roller and the movable coating roller through a paint nozzle. The outer walls of the auxiliary coating roller and the movable coating roller are in contact with the conductive cloth, so that when the conductive cloth is conveyed, the auxiliary coating roller and the movable coating roller can be driven to rotate, so that the paint is applied to the outer wall of the conductive cloth. This spraying method is prone to problems such as uneven distribution of paint on the coating roller and insufficient thickness of the paint layer, which affects the coating quality of the conductive cloth.

DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0020] Example: Figure 1-3 As shown, a conductive cloth anti-penetration treatment device includes a frame 1, a coating mechanism 2 and a scraping mechanism 3. The coating mechanism 2 and the scraping mechanism 3 are arranged on the frame 1, and the scraping mechanism 3 is located behind the coating mechanism 2.

[0021] The coating mechanism 2 includes a slurry tank 201 and a coating roller 202 disposed above the slurry tank 201. The coating roller 202 is rotatably mounted on the frame 1 and driven by a motor. The coating roller 202 has grooves 2021 evenly distributed on its surface. The grooves 2021 are linearly distributed along the axial direction and circumferentially distributed on the roller surface with the axis as the center. The grooves 2021 are staggered in the front and back directions in the circumferential direction.

[0022] A guide plate 203 is provided on the lower side of the coating roller 202 , and a gap for the slurry to pass through is formed between the guide plate 203 and the roller surface of the coating roller 202 . A slurry injection mechanism is provided between the upper end of the guide plate 203 and the slurry box 201 .

[0023] The upper end of the guide plate 203 is an inclined straight plate, and the lower end of the guide plate 203 is an arc-shaped structure leaning against the coating roller 202. The distance between the guide plate 203 and the roller surface of the coating roller 202 gradually decreases from top to bottom.

[0024] The slurry injection mechanism includes a slurry outlet 2031 arranged at the upper end of the guide plate 203, a material pipe 204 connected between the slurry outlet 2031 and the slurry box 201, and a pump body 205 connected to the material pipe 204. The pump body 205 can be a conventional centrifugal pump. The slurry in the slurry box 201 is pumped to the slurry outlet 2031 under the action of the pump body 205. The slurry enters between the guide plate 203 and the roller surface of the coating roller 202 through the slurry outlet 2031. Since the distance between the guide plate 203 and the roller surface of the coating roller 202 gradually decreases from top to bottom, the slurry cannot flow out in time and accumulates on the guide plate 203. When the slurry passes through the roller surface of the coating roller 202, it adheres to the roller surface and groove 2021 of the coating roller 202. The other part of the slurry flows into the slurry box 201 from the lower end of the guide plate 203. In this way, the slurry is always in a flowing state during the sizing process.

[0025] Slide blocks 207 are provided at the left and right ends of the guide plate 203 , and vertical slide rails 208 are installed on the inner wall of the slurry box 201 . The guide plate 203 is slidably installed on the slurry box 201 through the slide blocks 207 and the slide rails 208 .

[0026] An adjustment assembly 206 for adjusting the height of the guide plate 203 is provided between the slurry box 201 and the guide plate 203. The adjustment assembly 206 includes a mounting plate 2061 fixed to the slurry box 201, a support block 2062 located above the mounting plate 2061 and fixed to the guide plate 203, and an adjustment screw 2063 connected between the mounting plate 2061 and the support block 2062. The adjustment screw 2063 is screwed to the mounting plate 2061, and the upper end of the adjustment screw 2063 is rotatably connected to the support block 2062.

[0027] When the guide plate 203 moves upward, the gap between the lower end of the guide plate 203 and the roller surface of the coating roller 202 becomes smaller, the permeability of the slurry on the guide plate 203 becomes smaller, and the slurry staying on the guide plate 203 increases; when the guide plate 203 moves downward, the gap between the lower end of the guide plate 203 and the roller surface of the coating roller 202 increases, the permeability of the slurry on the guide plate 203 increases, and the slurry staying on the guide plate 203 decreases.

[0028] A tensioning adjustment mechanism 4 is provided on the front side of the coating roller 202. The tensioning adjustment mechanism 4 includes a tensioning frame 401 and a tensioning roller 402 arranged on the tensioning frame 401. The tensioning roller 402 and the coating roller 202 are respectively located on the upper and lower sides of the conductive cloth. The tensioning frame 401 is slidably installed on the frame 1 and moves up and down by the cylinder to adjust the tension of the conductive cloth.

[0029] The scraping mechanism 3 consists of two upper and lower scrapers, which are installed on the frame 1 through a blade holder and press against the upper and lower sides of the conductive cloth with a certain pressure to scrape the slurry on the conductive cloth flat.
