[0002] Photosensitive film, also known as film, film paper. It is made of a plastic transparent film as the base, on which a certain thickness of photosensitive emulsion is coated. Before the production of photosensitive film, its raw materials need to be screened and filtered to make the raw materials of photosensitive film meet the production conditions. Generally, a vibrating screening machine is used for screening.

[0003] When the existing vibrating screening machine screens the photosensitive film raw materials, since the discharge pipe is directly connected to the inside of the sieve plate, when the screening time of the photosensitive film raw materials is short or a large amount of photosensitive film raw materials are put in at one time, the photosensitive film raw materials that are not completely screened will directly enter the discharge pipe from the sieve plate, resulting in incomplete screening of the photosensitive film raw materials. Therefore, it is necessary to improve a device that can block the sieve plate and the discharge pipe to prevent the raw materials that are not completely screened from entering the discharge pipe. Utility Model Content

[0035] The fixed groove 21 is used to place the baffle 22, the baffle 22 is used to block the outer end of the discharge pipe 15, the telescopic spring 23 is used to drive the movable plate 24 to reset, the movable plate 24 is used to limit the baffle 22, the fixed column 25 is used to drive the baffle 22 to move, the top block 26 is used to limit the fixed column 25, and the limiting column 27 is used to block the movable plate 24;

[0036] The screening machine assembly also includes a vibration base 11, a vibration spring 12, a screen 14 and a discharge pipe 15;

[0037] The vibration spring 12 is fixedly connected to the upper and surrounding positions of the vibration base 11, the sieve plate 13 is fixedly connected to the upper end of the vibration spring 12, the sieve 14 is fixedly connected to the bottom end of the sieve plate 13, and the discharge pipe 15 is fixedly connected to the outer side of the sieve plate 13;

[0039] The fixed groove 21 is located outside the discharge pipe 15, and the movable plate 24 is located inside the two sides of the baffle plate 22;

[0040] When the baffle 22 is located inside the fixed groove 21, the baffle 22 prevents the raw materials on the screen 14 from entering the discharge pipe 15;

[0041] The fixing column 25 extends outward through the sieve plate 13, and the limiting column 27 is an inverted L-shaped structure;

[0042] By applying an inward force to the top block 26, the fixing column 25 can drive the baffle 22 to move inward;

[0043] Working principle: when it is necessary to prevent the raw materials on the screen 14 from directly entering the discharge pipe 15, an inward force is applied to the movable plate 24 to make the movable plate 24 move toward the inside of the baffle 22, and the movable plate 24 moves to the internal position on both sides of the baffle 22, and drives the telescopic spring 23 to be compressed, and applies an outward force to the top block 26, the top block 26 moves outward to drive the fixed column 25 to move outward, and the fixed column 25 moves outward to drive the baffle 22 to move into the fixed groove 21, and the movable plate 24 applies outward pressure to both sides of the fixed groove 21 under the elastic force of the telescopic spring 23, so that the baffle 22 is fixed inside the fixed groove 21, so that the baffle 22 blocks the space between the sieve plate 13 and the discharge pipe 15;

[0050] The wind generated by the fan can be blown upward through the air inlet pipe 31 and the baffle 32, so that the impurities are blown upward to the top of the fixed plate 33, while the raw materials are kept below the fixed plate 33;

[0051] Working principle: After the raw materials are screened, some impurities with a particle size similar to that of the raw materials will enter the discharge pipe 15 together with the raw materials. At this time, the fan is started, and the wind is generated by the fan and blows vertically upward through the air inlet pipe 31, so that the raw materials are kept above the baffle 32 and below the fixed plate 33. The impurities are blown to the top of the fixed plate 33 and discharged outward through the impurity discharge pipe 34, so that the impurities and the raw materials are separated, thereby completing the impurity removal of the raw materials, so that the screened raw materials do not need to be cleaned.
