A flat film scraping machine

Abstract

The embodiment of the invention discloses a flat-plate film scraping machine. The working table of the flat-plate film scraping machine is provided with a water tank, a pushing mechanism for pushing the water tank to move closer to or away from the working table, and a heating mechanism for drying the film body. . After the film scraping is completed, the pushing mechanism moves the water tank to the direction close to the workbench, and immerses the film body on the film forming base on the workbench into the water in the water tank for curing. After the curing is completed, the pushing mechanism drives the water tank to move away from the workbench, and finally, the heating mechanism is turned on to dry the film body. Since the water tank in this flat-plate film scraping machine can not only directly immerse the workbench into the water tank, but also directly dry the membrane body on the workbench, therefore, there is no need to move the membrane body, and it is not necessary to A support plate is set to support the membrane body during the film scraping process. In this way, the problem of affecting the precision of the ultrafiltration membrane caused by the use of the support plate can be avoided, thereby improving the precision of the ultrafiltration membrane to a certain extent.

Description

technical field [0001] The invention relates to a film scraping machine, more specifically, to a flat-plate film scraping machine. Background technique [0002] Ultrafiltration membrane is a microporous filtration membrane with consistent pore size and rated pore size range of 0.001-0.02 microns. Appropriate pressure is applied on one side of the membrane to screen out solute molecules smaller than the pore size to separate particles with a molecular weight greater than 500 Daltons and a particle size greater than 2-20 nanometers. Household water purifiers use the principle of ultrafiltration membranes to treat water quality. [0003] At present, the flat ultrafiltration membrane on the household water purifier is formed by a flat scraping machine. The existing flat film scraping machine includes a workbench, the upper surface of which is a film forming base; a driving mechanism fixed on the workbench; and a film scraping mechanism connected with the driving mechanism.

Problems solved by technology

The support plate needs to be manually moved up and down each time. Frequently moving the support plate makes the support plate easy to damage, and the support plate after scraping the film needs to be put into the drying oven for drying. Due to the small thickness of the support plate, the temperature is often changed. The accuracy of the environment is also gradually reduced, and the reduction of the accuracy of the support plate will inevitably affect the accuracy of the ultrafiltration membrane.
