Problems solved by technology
[0008] However, in the actual human operation process, due to the uneven force and uneven coating speed during manual coating, the coating effect is quite different. Therefore, it is necessary to use machinery instead of manual coating to achieve uniform force application. control, the coating speed can be uniformly controlled within a certain range
[0009] At present, the price of coating machines used in laboratories in the market is relatively high, the mechanical structure is relatively complicated, and the maintenance and cleaning are cumbersome. The way of motor transmission is relatively complicated and it is difficult to control the coating accuracy

Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] The coating device of the present invention is mainly used for laboratory coating operations. Use this device to automatically and uniformly coat the material to be coated fixed on the substrate.
[0031] The specific design scheme of the device of the present invention: a laboratory uniform coating device, the main body is composed of a base 2, a substrate 1, a screw assembly, a coater and the like.
[0032] Among them, the OSP wire rod 5 is used as the applicator, which is connected with the two pressurizing elements 6 and the ball linear guide rail slide table, and the connecting element 7 is used at the junction of the three. The coater is located on the coating surface of the substrate, and the coater is driven by the uniform motion of the ball linear guide slide table to evenly coat the coating liquid on the substrate.

The invention discloses a constant-speed coating device for a laboratory. According to the constant-speed coating device, a main body comprises a base, a base plate, a lead screw assembly, a coater and the like. The coating device can be used for automatically coating a material to be coated which is fixed to the base plate at a constant speed in the laboratory. According to the technology of thecoating device, the lead screw assembly is driven to operate at a constant speed so as to drive the coater to stably, horizontally and uniformly coating the base material at a constant speed. The coating device has the advantages of being simple and easy to operate, capable of being automatically operated and assembled and capable of effectively solving the problems of force application and uniform coating in the film coating experiment process .
Description
technical field [0001] The invention relates to the field of medical film production, in particular to a laboratory uniform-speed coating device. Background technique [0002] At present, there are roughly the following methods for continuously and uniformly coating the coating liquid on the surface of the required substrate: dip coating, roll coating, doctor blade coating, comma coating, gravure coating, narrow coating, etc. Slot die extrusion coating, metered rod coating, spray coating and other rotary coating. Among them, the most widely used are roll coating, knife coating, gravure coating and slot die extrusion coating. [0003] Roller coating is difficult to form a transfer film with a specified film thickness on the transfer roller surface that is always rotating stably, so use a wiper to scrape off the excess transfer film on the transfer roller surface to ensure the specified transfer Film thickness. The utilization rate of the coating material is reduced, and th...
