Description

A knife coating device for laboratory functional coating evenly coats

Technical Field

The invention relates to the field of coating equipment, in particular to a blade coating device for uniformly coating a functional coating in a laboratory.

Background

Since various types of coatings are involved in experimental studies relating to films and coatings, including substances with very high system viscosity, they are often applied uniformly by means of knife coating; blade coating is a method of coating by a bar or blade, etc. The knife coating mode is generally that the coating is dispersed on the substrate, and then the coating is scraped back and forth by a scraping rod or a scraping plate so as to be uniformly distributed and have a flat surface; the thickness and quality of the coating are greatly influenced by manual operation, and the problems of low efficiency, unsatisfactory effect and the like exist, which greatly limits the rigor of scientific research, so that a blade coating device capable of controlling the thickness and uniformity of the coating is necessary.

Common coating methods also include drop coating, line coating, spin coating and the like, but the spin coating method is affected by surface tension to cause uneven coating on the edge part of the substrate, has an undesirable effect on coating with high system viscosity, and wastes coating. Therefore, the traditional method has the problems of incapability of uniformly coating in a large area, low preparation efficiency, long time consumption, poor effect and high production cost.

Detailed Description

In order to facilitate understanding of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the drawings and the specific embodiments. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For convenience of description, the terms "upper", "lower", "left" and "right" in this disclosure merely indicate directions in the drawings, and are used only for describing the present invention, and do not indicate that the structures referred to must have a specific orientation, and thus, should not be construed as limiting the present disclosure.

As described in the background art, the conventional coating method has problems of no uniform coating over a large area, low preparation efficiency, long time consumption, poor effect and high production cost. In view of the above problems, the present invention provides a blade coating device for uniformly coating a functional laboratory coating, the details of which will be described in the following embodiments.

Referring to fig. 1, as shown in the figure, the embodiment of the present invention provides a knife coating apparatus for uniformly coating a functional coating in a laboratory, the apparatus includes a base 1, a tray 2, a rotary table 3, a knife coating rod 4, a fastening knob 5, a fixing rod 6, and a column 7 with a scale.

The working principle of the invention is as follows: when the scraping device for uniformly coating the laboratory functional paint is used, the relative position of the scraping rod 4 can be adjusted through the fixing rod 6 and the fastening knob 7 to control the thickness of the coating, the paint is dripped on the surface of the base material after the adjustment is finished, at the moment, the scraping rod 4 is kept static relative to the fixing rod 6, the rotary table 3 drives the base material to start rotating, the scraping rod 4 uniformly scrapes the paint on the surface of the base material, and the tray 2 is used for collecting the redundant paint in the scraping process.
