[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 4 , a paste filling material screening device, comprising:

[0026] The box body 1 is connected with a feed hopper 2 on the top of the box body 1;

[0027] The screening mechanism includes a grid 3, a filter screen 4, an arc seat 5, an electric telescopic rod 6 and a cable 7. A plurality of grids 3 are rotatably connected to one side of the box body 1, and a plurality of arc seats 5 are fixedly connected to the other side. The plurality of grids 3 are fixedly connected to the filter screen 4. The ends of the plurality of grids 3 away from the inner wall of the box body 1 are slidably connected to the plurality of arc seats 5 in a one-to-one manner. An electric telescopic rod 6 is installed on the top of the box body 1. The output end of the electric telescopic rod 6 is fixedly connected to the cable 7. The end of the cable 7 away from the electric telescopic rod 6 is fixedly connected to the plurality of grids 3. A plurality of side openings 9 are opened on one side of the box body 1, and the plurality of side openings 9 are arranged one-to-one above the plurality of arc seats 5.

[0028] A valve assembly, wherein an input end of the valve assembly is connected to an output end of the electric telescopic rod 6 , and the output end of the valve assembly cooperates with a plurality of side openings 9 .

[0029] The discharge port 14 is opened at the bottom of the box body 1.

[0030] The arc seat 5 is arc-shaped at a side away from the box body 1 , and the center of the arc coincides with the rotation axis of the grid frame 3 .

[0031] The grid 3 is initially arranged in an inclined manner, wherein the inclined bottom end of the grid 3 points to the side opening 9 .

[0032] The apertures of the meshes of the plurality of filter screens 4 gradually decrease from top to bottom.

[0033] The bottoms of the multiple grids 3 are all fixedly connected with return springs 8 , and one end of the return spring 8 away from the bottom of the grid 3 is fixedly connected to the arc seat 5 .

[0034] The valve assembly includes a sealing plate 11, a fixed rod 12 and a connecting rod 13. A sliding cavity 10 is opened in the inner wall of the box body 1. The sliding cavity 10 is communicated with multiple side openings 9. Multiple sealing plates 11 are sealed and slidably connected in the sliding cavity 10. The multiple sealing plates 11 correspond to the multiple side openings 9 one by one. The multiple sealing plates 11 are fixedly connected to the same fixed rod 12. The top of the fixed rod 12 is fixedly connected to the connecting rod 13. The connecting rod 13 penetrates the box body 1 at one end away from the fixed rod 12, and is fixedly connected to the output end of the electric telescopic rod 6.

[0035] The connecting rod 13 includes an inverted U-shaped rod.

[0036] The operating principle of the utility model is now described as follows:

[0037] During operation, the paste filling material is passed into the box body 1 through the feed hopper 2, and the electric telescopic rod 6 is started. The output end of the electric telescopic rod 6 reciprocates and retracts, thereby driving the multiple grids 3 to reciprocate through the cable 7, so that one end of the grid 3 reciprocates in the middle and lower part of the arc seat 5, and the paste filling material is screened multiple times through the multiple filter screens 4. During this process, the multiple sealing plates 11 always keep the side opening 9 sealed, effectively preventing the paste filling material from being directly discharged through the side opening 9, thereby improving the screening effect of the paste filling material;

[0038] After the screening is completed, the reciprocating motion and contraction of the output end of the electric telescopic rod 6 are controlled to make one end of the grid 3 reciprocate in the middle and upper part of the arc seat 5. At the same time, the connecting rod 13 and the fixed rod 12 pull the multiple sealing plates 11 to slide upward to open the side opening 9. When convenient, the paste filling material screened on the filter screen 4 can quickly pass through the filter screen 4 and be output from the side opening 9.
