Blade coating unit for soft carriage material

Abstract

The invention provides a blade coating device for a soft carriage material, and solves the technical problems that when the conventional blade coating device is used for blade coating of carriage materials, as a scraper is unadjustable in blade coating width, the conventional blade coating device adapt to the carriage materials of different widths and is narrow in application range. The blade coating device provided by the invention comprises a rack, wherein a scraper is fixed on the rack; a working cavity is formed in the scraper; a feed opening communicated with the working cavity is formed in the upper part of the scraper; a plurality of discharge openings communicated with the working cavity are formed in the lower part of the scraper; a first guide groove and a second guide groove are formed in two sides of the scraper and both communicated with the working cavity; a first adjusting plate is arranged in the first guide groove; a second adjusting plate is arranged in the second guide groove; a scraper coating roller is arranged below the scraper and connected with a lifting mechanism which can drive the scraper coating roller to move up and down; the scraper coating roller can be in contact with the scraper. The blade coating device has the advantage of strong universality.

Description

technical field [0001] The invention belongs to the technical field of coating, and relates to a scraper coating device, in particular to a scraper coating device used for soft vehicle compartment materials. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation, and decoration. The paint can be in gaseous, liquid, or solid state. The type and state of the paint depends on the substrate to be sprayed. There are many coating methods, which can be mainly classified into two types: doctor blade method and roller coating method. [0003] After searching, for example, Chinese patent literature discloses a scraper coating device for a coating machine [application number: 201220222373.X; announcement number: CN202595575U]. The scraping device of this coating machine includes a paint frame, and it is characterize...

Problems solved by technology

[0004] Although the squeegee coating device disclosed in this patent has simple structure, high precision, uniform coating, and controllable coating, when the squeegee coating device is used for squeegee coating of vehicle compartment materials, the squeegee width of the scraper cannot be adjusted, and cannot adapt to different The width of the carriage material is narrow, so it is necessary to design a scraping device for soft carriage materials
