Constant-speed smearing mechanism suitable for applying paste dressing

Abstract

The invention provides a constant-speed smearing mechanism suitable for applying a paste dressing. The constant-speed smearing mechanism comprises a supporting plate; the supporting plate is of a rectangular structure; a first protective shell is mounted at the bottom of the supporting plate; a spraying mechanism is mounted above the inner side of the first protective shell; a smearing structure is mounted at the bottom of the inner side of the first protective shell; an auxiliary scraping mechanism is mounted on the outer side of the first protective shell; and an extrusion mechanism is mounted at the bottom of the supporting plate. The effect of cleaning dust adhered to cloth is achieved through the arrangement of a cleaning brush; specifically, sliding shafts are arranged on the two sides of the cleaning brush, and the sliding shafts have the effect of supporting the cleaning brush; springs for pushing the sliding shafts to reset are arranged on the sliding shafts; a cam driven by a servo motor is arranged on one side of the corresponding sliding shaft; and the servo motor has the effect of driving a mounting seat to rotate, so that the cam pushes the cleaning brush to reciprocate, and the cleaning effect of the cleaning brush on the dust on the cloth is better.

Description

technical field [0001] The invention belongs to the technical field of coating, and more specifically relates to a uniform-speed coating mechanism suitable for coating paste dressings. Background technique [0002] Coating refers to coating the paint on the surface of base paper and cloth in a specific way to achieve the purpose of improving the surface properties of base paper and cloth, so as to ensure that the coated paper and cloth have good and stable appearance quality and adhesion performance. During the process, the paste dressing will be applied on the base paper and the surface of the cloth through a roller. The existing coating device will spread unevenly when applying the paste. It is necessary to adjust the structure of the coating mechanism on the coating device. renew. [0003] The uniform-speed coating mechanism suitable for coating paste dressings can refer to patent No. CN201711377051.6, which discloses a coating machine coating mechanism, including a vert...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a uniform-speed coating mechanism suitable for coating paste dressings to solve the problem that a large amount of paste will adhere to the surface of the roller after the existing coating roller stops dressing. The paste on the roller will produce bacteria after being placed for a period of time, and the paste on the roller will also appear to dry and condense after being placed for a period of time. The paste on the roller needs to be cleaned. It is cumbersome to clean up manually. When applying paste dressing, the paste material may be mixed with larger particles. After the paste dressing mixed with particles is directly sprayed on the cloth, dressing will appear. Inhomogeneity, there will be dust attached to the surface before the cloth dressing, the dust is easy to breed bacteria, affecting the adhesion of the paste and causing layering.
