Embodiment 1

[0035] This embodiment is basically as figure 1 , image 3 and Figure 5Shown: an integrated flat film scraper coating machine, including a frame 1, a workbench 2, a water tank 3, a liquid adding mechanism, a scraping mechanism and a roller shutter mechanism. The liquid feeding mechanism includes a cylinder body 4 and an arc-shaped overflow groove 5, and the cylinder body 4 is horizontally slidably connected to the frame 1, specifically, combined with Figure 4 As shown, the peripheral wall of the cylindrical body 4 is fixedly connected with two opposite installation shafts, and the installation shafts are coaxially rotatably connected with a pulley 6, and the frame 1 is provided with a guide groove for the pulley 6 to slide horizontally. recombine figure 1 As shown, the inside of the cylinder 4 is provided with a stirring shaft 7, the top of the stirring shaft 7 is fixedly connected with a driving motor 8, the top of the cylinder 4 is welded with a horizontal plate through...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that: Figure 6 As shown, a piston cylinder 39 is fixedly installed on the mounting bracket 12 by bolts, and a piston 40 is horizontally slidably connected in the piston cylinder 39. The piston 40 seals the inner space of the piston cylinder 39 into a chamber 41, and an electric heater is fixedly installed in the chamber 41. wire42. The left side wall of the piston 40 is welded with a special-shaped piston rod 43 , and the end of the piston rod 43 away from the piston 40 is welded with the drawbar 15 . The chamber 41 of piston cylinder 39 is communicated with intake pipe 44, air outlet pipe and exhaust pipe 45, and outlet pipe is positioned at the top of piston cylinder 39, and the first one-way valve that gas is introduced into chamber 41 is installed on the inlet pipe 44, and air outlet pipe A second one-way valve for leading the gas out of the chamber 41 is installed on the top, and a vent valve is installed...

Abstract

The invention relates to the field of film preparation, and discloses an integrated flat sheet film blade coating machine. The integrated flat sheet film blade coating machine comprises a rack, a workbench, a film scraping mechanism and a liquid adding mechanism, wherein the liquid adding mechanism comprises a barrel body and an arc-shaped overflow groove; the barrel body is horizontally connectedonto the rack in a sliding mode; a stirring shaft is arranged inside the barrel body; the stirring shaft is fixedly connected with stirring blades; the bottom of the barrel body communicates with a liquid outlet tube for guiding film-making liquid into the arc-shaped overflow groove; a liquid outlet valve is mounted on the liquid outlet tube; the film scraping mechanism comprises a telescopic aircylinder, a traction rod and a film scraping base; the film scraping base is fixedly connected to the output end of the telescopic air cylinder through the traction rod; the arc-shaped overflow groove is fixedly connected to the side wall of the film scraping base; the top of one side wall, away from the film scraping base, of the arc-shaped overflow groove is outwards bent to form an overflow hole; and the barrel body is fixedly connected with the output end of the telescopic air cylinder. According to the integrated flat sheet film blade coating machine disclosed by the invention, the liquid adding mechanism is utilized to pre-mix the film-making liquid, so that the film-making liquid is uniform in liquid quality; and the film-making liquid is dispersed and dropped onto a carrier, so that the film-making liquid is prevented from being accumulated, and therefore, the film-making liquid is scraped to be flat more favorably.

Description

technical field [0001] The invention relates to the field of film preparation, in particular to an integrated flat film scraper coater. Background technique [0002] Ultrafiltration membrane is a microporous filtration membrane with uniform pore size and rated pore size range of 0.001-0.02 μm. Appropriate pressure is applied to one side of the membrane to screen out solute molecules smaller than the pore size to separate molecular weights greater than 500 Daltons, particles with a particle size greater than 10nm. [0003] At present, the flat ultrafiltration membrane can be prepared by a flat-type film scraping machine. The main preparation process of the flat ultrafiltration membrane is as follows: lay non-woven fabric or other materials on the working table of the scraping machine as a carrier, and use the scraping mechanism to remove the The membrane liquid is evenly spread on the carrier, then the membrane body is solidified in water, and finally the membrane body is se...
