Description

Technical Field

[0001] This utility model relates to the field of fabric coating technology, specifically to a surface coating processing equipment. Background Technology

[0002] Coating is a process in which a liquid or slurry material with a specific function (called a "coating liquid" or "coating") is uniformly applied to the surface of a substrate, and then dried and cured to form a uniform, continuous film with a certain thickness and function.

[0003] A utility model patent with publication number CN223027700U describes a coating machine for fabric production, comprising a base and two vertical plates slidably connected to the upper surface of the base. A driving device is provided on the base to move the two vertical plates. Mounting frames are rotatably connected to the sides of the two vertical plates closest to each other. Unwinding rollers and take-up rollers are rotatably connected to the mounting frames on both sides, respectively. A bracket is slidably connected to the upper surface of the base, and a driving mechanism is provided on the upper surface of the base to move the bracket. A glue storage tank is fixedly connected to the side wall of the bracket. An applying roller, rotatably connected to the bracket, is located above the glue storage tank. A pressure roller, rotatably connected to the bracket, is located above the applying roller. This utility model achieves double-sided coating by using a driving mechanism to move the pressure roller and the applying roller, and flipping the fabric after they are separated.

[0004] In this scheme, the coating process on both sides of the fabric is separated. After coating one side of the fabric, the device flips the take-up roller and the unwind roller to coat the other side of the fabric. This results in a complex structure for the device, but the improvement in coating efficiency is limited.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a surface coating processing equipment that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a surface coating processing equipment, comprising: a base, a fabric, and a coating mechanism for coating both sides of the fabric; The coating mechanism includes: a motor, a mounting frame mounted on the output shaft of the motor, a take-up roller and an unwind roller fixedly mounted on the mounting frame, a paint roller mounted below the take-up roller and the unwind roller, the paint roller being fixedly mounted on a roller shaft, and the roller shaft being rotatably mounted on a paint box.

[0008] Furthermore, mounting plates are fixedly installed on both sides of the paint box, and limit rods slide and pass through the mounting plates, with springs sleeved on the limit rods.

[0009] Furthermore, a limit block is fixedly installed at the upper end of the limiting rod.

[0010] Furthermore, the length of the spring is greater than the length of the limiting rod.

[0011] Furthermore, the two ends of the fabric are respectively connected to the take-up roller and the unwind roller, and the winding direction of the fabric on the take-up roller and the unwind roller is opposite.

[0012] Furthermore, a limiting disc is fixedly installed on the take-up roller and the unwind roller, and the diameter of the coating roller is larger than the diameter of the limiting disc.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a surface coating processing equipment, which uses a take-up roller to take up the fabric on the unwinding roller. During the process of the fabric being taken up by the take-up roller, two coating rollers coat both sides of the fabric respectively, thereby improving the coating efficiency. In addition, the coating rollers press the fabric tightly to prevent the fabric from loosening after being rolled up. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 3 As shown, the present invention provides a surface coating processing device, comprising: a base 1, a fabric 4, and a coating mechanism 3 for coating both sides of the fabric 4; four vertical plates 2 are fixedly installed on the base 1, the four vertical plates 2 are symmetrically distributed on the top of the base 1, and the coating mechanism 3 is installed on the vertical plates 2, through which the fabric 4 is unfolded and coated on both sides of the fabric 4.

[0022] The coating mechanism 3 includes: a motor 31, which is fixedly mounted on a vertical plate 2. Four mounting frames 32 are rotatably mounted on each of the four vertical plates 2. Each mounting frame 32 is fixedly mounted on the output shaft of the motor 31. Two aligned mounting frames 32 form a group. A take-up roller 33 and an unwind roller 34 are fixedly mounted on each of the two groups of mounting frames 32. The take-up roller 33 is aligned with the output shaft of the motor 31. The output shaft of the motor 31 drives the mounting frame 32 to rotate, which in turn drives the take-up roller 33 to rotate, thus winding the fabric 4. Both ends of the fabric 4 are connected to the take-up roller 33 and the unwind roller 34, respectively. The winding directions of the fabric 4 on the take-up roller 33 and the unwind roller 34 are opposite. When the winding roller 33 rotates clockwise and winds up the fabric 4, the fabric 4 wound counterclockwise on the unwind roller 34 is released, causing the unwind roller 34 to rotate clockwise. The surface of the fabric 4 that is in direct contact with the winding roller 33 is different from the surface of the fabric 4 that is in direct contact with the unwind roller 34. A coating roller 35 is installed below both the winding roller 33 and the unwind roller 34. The coating roller 35 is fixedly mounted on the roller shaft 36, which is rotatably mounted on the coating box 37. The upper part of the coating roller 35 is located outside the coating box 37. The two coating rollers 35 respectively coat the fabric 4 located on the outer side of the unwind roller 34 and the winding roller 33, so that the coating of both sides of the fabric 4 can be carried out simultaneously, improving the coating efficiency.

[0023] Mounting plates 38 are fixedly installed on both sides of the paint box 37. A vertical limiting rod 39 slides and passes through the mounting plate 38. A limiting block is fixedly installed on the upper end of the limiting rod 39 to limit the movement range of the mounting plate 38 and prevent the mounting plate 38 from separating from the limiting rod 39. A spring 310 is sleeved on the limiting rod 39. One end of the spring 310 is fixedly connected to the mounting plate 38, and the other end of the spring 310 is fixedly connected to the base 1. The spring force of the spring 310 pushes the mounting plate 38, causing the mounting plate 38 to drive the paint box 37 to rise. The paint box 37 drives the roller shaft 36 to rise, and the roller shaft 36 drives the paint roller 35 to rise, so that the paint roller 35 contacts the fabric 4. The take-up roller 33 and the unwind roller 34 block the paint roller 35, so that while the paint roller 35 is coating the fabric 4, the paint roller 35 presses the fabric 4 tightly onto the unwind roller 34 and the take-up roller 33, so that the coating effect is stable and the fabric 4 is prevented from loosening.

[0024] Furthermore, the length of spring 310 is greater than the length of limit rod 39. After spring 310 pushes mounting plate 38 into contact with limit block, the elastic force of spring 310 is still greater than the sum of the weights of mounting plate 38, paint box 37, paint in paint box 37, roller 36 and paint roller 35. The elastic force of spring 310 can make paint roller 35 press fabric 4 tightly. When fabric 4 is unwound or wound up, fabric 4 drives paint roller 35 to rotate, so that paint roller 35 will not obstruct unwound and wound up fabric 4.

[0025] It should be added that a limiting plate is fixedly installed on the take-up roller 33 and the unwind roller 34. The limiting plate limits the fabric 4 to prevent the fabric 4 from shifting. The diameter of the coating roller 35 is larger than the diameter of the limiting plate, so that the coating roller 35 can maintain contact with the fabric 4 on the take-up roller 33 and the unwind roller 34. When the coating roller 35 contacts the take-up roller 33 or the unwind roller 34, the limiting plate does not contact the roller shaft 36, so that the limiting plate will not obstruct the movement of the coating roller 35.

[0026] Working principle: By reversing the winding and unwinding directions of the fabric 4, the fabric 4 is unwound from the bottom of the unwinding roller 34 and coated by the coating roller 35 below the unwinding roller 34 during unwinding. The fabric 4 is then wound up from the top of the winding roller 33 and coated by the coating roller 35 below the winding roller 33 during winding. This allows both sides of the fabric 4 to be coated in one unwinding and winding process, improving coating efficiency. At the same time, the coating roller 35 presses the fabric 4 firmly, ensuring that the coating roller 35 is in contact with the fabric 4 on the winding roller 33 and the unwinding roller 34, guaranteeing the coating effect and preventing the fabric 4 from loosening, thus ensuring the winding effect.
