[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1As shown, a photosensitive resin filtering device includes a collecting box 2, a filtering box 3 and a base 1, a filtering hole 302 is provided at the bottom of the filtering box 3, the filtering box 3 is docked with the upper end of the collecting box 2, the collecting box 2 is placed on the upper end of the base 1, a bracket 102 is connected to one side of the base 1, a hydraulic cylinder 5 is provided on the bracket 102, a piston 4 that cooperates with the filtering box 3 is connected to the piston 4 rod of the hydraulic cylinder 5, a stirring shaft 303 is provided in the filtering box 3, the stirring shaft 303 is close to the bottom of the filtering box 3, the maximum downward position of the piston 4 will not touch the stirring shaft 303, and a motor 301 connected to the stirring shaft 303 is fixed on the outer wall of the filtering box 3.

[0025] like Figure 2 As shown, the upper end of the base 1 is provided with a positioning bar 101 that cooperates with the side wall of the collection box 2. The position of the collection box 2 is fixed by the positioning bar 101, which can prevent the collection box 2 from sliding and ensure the reliability of the cooperation between the piston 4 and the filter box 3.

[0026] like Figure 3-4 As shown, the bottom of the filter box 3 is a V-shaped structure, which can make the liquid resin gather to the stirring shaft 303, accelerate the flow through the stirring of the stirring shaft 303, and prevent solid impurities from clogging the filter hole 302 during the stirring process. The upper end of the collection box 2 is provided with a mounting groove 202 that matches the bottom of the filter box 3, and the outer side of the mounting groove 202 is provided with a baffle 201 for fixing the filter box 3 to ensure the firmness of the filter box 3 and the collection box 2.

[0027] like Figure 5 As shown, the piston 4 is made of rubber, and a pressure plate 401 connected to the hydraulic cylinder 5 is provided at the upper end of the piston 4. The length and width of the pressure plate 401 are smaller than the piston 4, which can ensure stable pushing and pulling of the piston 4 without affecting the extrusion deformation of the piston 4 when it cooperates with the filter box 3.

[0028] The lower end of the piston 4 is connected to a scraper 402 through a connecting block 403. The scraper 402 cooperates with the inner wall of the filter box 3. As the piston 4 is pushed downward, the scraper 402 can scrape the liquid resin on the inner wall of the filter box 3 and push it downward, thereby improving the thoroughness of the filtration.

[0029] like Figure 6 As shown, when in use, the collecting box 2 is placed on the base 1, and the filtering box 3 is installed on the upper end of the collecting box 2.

The hydraulic cylinder 5 is started to make the piston 4 cooperate with the filtering box 3, and the stirring shaft 303 is started to rotate and stir. As the piston 4 slowly moves downward, the liquid resin flows downward faster to achieve filtering of the liquid resin.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
