The screen printing plate is usually made of polyester or metal screen by a photoengraving process, and the mesh number of the screen hole can be adjusted according to the printing accuracy requirement. Generally, in continuous printing operation, ink, curing resin and other materials will gradually block the screen hole, especially when printing high viscosity UV ink or ceramic slurry containing fillers, the screen hole blockage rate can reach more than 30%, so regular cleaning is necessary to maintain printing quality. At present, most enterprises still adopt manual cleaning method: workers need to hold a brush and dip it in cleaning solution, and then repeatedly brush and wash the surface of the screen printing plate.

[0032] First, the screen printing plate is clamped and held by the clamping driving mechanism 2, then the screen printing plate is sprayed and washed by the spray washing mechanism 3, then the screen printing plate is driven to move into the water storage area 11 by the clamping driving mechanism 2, then the screen printing plate is brushed by the brushing mechanism 4 and the residual ink on the screen printing plate is removed by the ultrasonic generator 12.

[0033] Reference Figure 2 and Figure 3, the clamping driving mechanism 2 comprises a rack 21 mounted on the box 1, a transverse reciprocating driving member 22 is mounted on the rack 21, a vertical reciprocating driving member 23 is connected with the transverse reciprocating driving member 22, the transverse reciprocating driving member 22 and the vertical reciprocating driving member 23 are both air cylinders, the transverse reciprocating driving member 22 is connected with a frame body 24, the frame body 24 is mounted with clamping members 25, the clamping members 25 are clamping air cylinders, a belt rotating member 26 is mounted on each clamping jaw of the clamping members 25, the belt rotating member 26 is a belt rotating air cylinder, each belt rotating member 26 is connected with a clamping block 27, a clamping groove 271 for clamping the end of the screen printing plate is formed on each clamping block 27; after the screen printing plate is clamped in the two clamping grooves 271 and clamped by the clamping members 25, the belt rotating member 26 can drive the screen printing plate to rotate, at this time, the spray and washing mechanism 3 can be used to spray and wash different positions of the screen printing plate to remove the ink as much as possible.

[0034] With reference to Figure 2 and Figure 4 , the spray and washing mechanism 3 comprises a reciprocating driving member 31 mounted on the outer wall of the box 1, the reciprocating driving member 31 is an air cylinder, the box 1 is provided with a mounting groove 13, the output end of the reciprocating driving member 31 is arranged in the mounting groove 13 and connected with a water baffle 32, the reciprocating driving member 31 can drive the water baffle 32 to move up and down, the water baffle 32 is used for shielding the mounting groove 13, a plurality of spray heads 33 are mounted on the water baffle 32, the specific structure of the spray heads 33 is the prior art and will not be described here, the plurality of spray heads 33 are located in the box 1 and face the screen printing plate clamped by the clamping members 25.

[0035] With reference to Figure 2 , the brushing mechanism 4 comprises a first rotating roller 41 and a second rotating roller 42 rotatably mounted on the box 1, the first rotating roller 41 and the second rotating roller 42 are arranged along the front and back directions, the first rotating roller 41 and the second rotating roller 42 are both located in the water storage area 11, the first rotating roller 41 and the second rotating roller 42 are both connected with a driving rotating member 43, the driving rotating member 43 is a motor; the outer wall of the first rotating roller 41 is provided with a plurality of soft thick hairs 411 densely arranged, the outer wall of the second rotating roller 42 is provided with a plurality of soft thin hairs 421 densely arranged, the transverse reciprocating driving member 22 and the vertical reciprocating driving member 23 can drive the screen printing plate to move to contact the soft thick hairs 411 or the soft thin hairs 421.

[0036] Different silk screen printing plates have different cleaning needs. For special materials such as some metal silk screen printing plates or thickened plastic silk screen printing plates, they have high strength and wear resistance, and are not easy to be damaged by rough brushes. At this time, soft rough hair 411 can be used for cleaning, which can more efficiently remove stubborn stains. Or when the ink on the screen plate is dried and cured for a long time, forming a very stubborn blockage, and the blocked ink layer is thick and large, soft fine hair 421 may not be able to clean it up in a short time. Soft rough hair 411 is relatively stiffer, and the spacing between soft rough hair 411 is larger. After being dipped in an appropriate amount of solvent, it can exert more friction and pressure, which helps to scrape off large pieces of dry and solidified ink from the silk screen printing plate, thereby speeding up the cleaning speed. For silk screen printing plates for high-precision printing, the mesh size is small and the wire is thin. In order to reduce friction and damage to the silk screen printing plate, it is necessary to use soft fine hair 421 for brushing.

[0037] With reference to Figure 4 In order to be able to remove too much ink impurities accumulated in the water storage area 11 in time, the box body 1 has a transparent part 14, which is made of, for example, plastic. The transparent part 14 is located on one side of the water storage area 11.

[0038] With reference to Figure 1 and Figure 2 A liquid level detection piece 15 is installed on the inner wall of the box body 1. The liquid level detection piece 15 is a liquid level sensor, and is located in the water storage area 11. A drain pipe 16 is installed on the box body 1 and communicates with the inside of the box body 1. The drain pipe 16 is provided with a valve 17. The box body 1 is also provided with a control module 18. The liquid level detection piece 15 and the valve 17 are electrically connected with the control module 18. The control module 18 can control the valve 17 to work in response to the detection signal of the liquid level detection piece 15.

[0039] Based on the liquid level sensor, the water amount of the water storage area 11 can be determined. When the water amount is too much, the control module 18 controls the valve 17 to work so that the water in the water storage area 11 flows out.

[0040] The implementation principle of the silk screen printing plate cleaning device according to an embodiment of the application is as follows:

[0041] Firstly, open the opening and closing door, and then drive the clamping member 25 to clamp the screen printing plate into the two clamping grooves 271, and then drive the horizontal reciprocating driving member 22 and the vertical reciprocating driving member 23 to move the screen printing plate to the side of the spray head 33, drive the belt rotating member 26 to rotate the screen printing plate, and drive the reciprocating driving member 31 to move the spray head 33 to spray and wash different positions of the screen printing plate; then, based on the type of the screen printing plate, drive the horizontal reciprocating driving member 22 and the vertical reciprocating driving member 23 to drive the screen printing plate into the water storage area 11 to contact the soft coarse hair 411 or the soft fine hair 421, drive the driving rotating member 43 to drive the first rotating roller 41 to rotate or the second rotating roller 42 to rotate to brush off the ink on the screen printing plate, and in addition, drive the ultrasonic generator 12 to cooperate to remove the possible small ink remaining on the screen printing plate.
