The working principle of the screen printing scraper device for the rear cover diaphragm of the mobile phone is as follows:
when the mobile phone rear cover membrane is required to be subjected to screen printing, firstly an operator can pull out the printing plate 4 from the printing screen frame 1 through the pull handle 401, then the mobile phone rear cover membrane required to be printed is placed into the mobile phone rear cover clamping groove 402, after the mobile phone rear cover membrane is placed into the mobile phone rear cover clamping groove 1 through the pull handle 401, the operator can start the starting motor 104 after pushing in, the starting motor 104 drives the reciprocating threaded rod 101 to rotate, the reciprocating moving part 2 is driven to reciprocate along the reciprocating threaded rod 101 along with the rotation of the reciprocating threaded rod 101, and as the driving pulleys 201 positioned at two sides of the reciprocating moving part 2 roll on the moving sliding rail 102, the heights of the front side and the rear side of the moving sliding rail 102 are different, when the reciprocating threaded rod 101 drives the reciprocating moving part 2 to the front end of the printing screen frame 1, the driving part 208 is driven to the upper side of the upper sliding groove 205 through the driving pulley 201, at the moment, the pulling force of the ink outlet baffle 213 is driven to overcome through the magnetic force absorbed between the adsorption magnetic block 209 and the triggering magnetic block, the ink outlet baffle 213 is driven to move along with the reciprocating threaded rod 101, the ink outlet 213 is not discharged from the ink outlet channel 213, and the ink outlet is not discharged from the ink outlet channel 206 is blocked from the outside;
with the continued rotation of the reciprocating threaded rod 101, the reciprocating member 2 is driven to slowly move to the rear side of the printing screen frame 1, the moving sliding rail 102 at the rear side of the printing screen frame 1 slowly becomes low, when the reciprocating member 2 moves to the rear side, the driving pulley 201 enables the driving member 208 to move downwards along the upper and lower sliding grooves 205, at this time, the distance between the adsorption magnetic block 209 and the triggering magnetic block becomes far, the magnetic force between the adsorption magnetic block 209 and the triggering magnetic block becomes weak, at this time, the tension spring 212 pulls the ink outlet baffle 213 rightwards through the tensile force, the ink is pulled into the ink outlet channel 210 through the hole 211, at this time, the ink blocked by the non-opening position of the ink outlet baffle 213 falls into the ink outlet tube 214 through the ink outlet hole 211 which enters into the ink outlet channel 210, and moves to the ink outlet through the inclined ink outlet hole 203, when the reciprocating member 2 reciprocates again, the reciprocating member 204 is pushed to a small amount of ink outlet 203 to the outgoing through the inclined ink outlet hole 203, and the reciprocating member 2 is driven to the outer side of the reciprocating member, at this time, the magnetic force is pulled back to the ink outlet channel 210 again through the reciprocating member 201 when the reciprocating member 2 moves to the front end of the printing screen frame 1 again, and the ink outlet channel is driven to the ink outlet through the magnetic block 201 to the ink outlet hole which is pulled to the ink outlet through the ink outlet hole 201 when the reciprocating member is reciprocally and the ink outlet hole is reciprocally moved to the ink outlet channel to the ink outlet position of the ink channel 2 again;
when the scraper 204 pushes ink reciprocally, if the scraper 204 is affected by the temperature of the external air, when the scraper 204 pushes ink to print with the reciprocating member 2, the sparse ink enters the sliding cavity 303 through the thin ink passing holes 202 and falls onto the driving plate 307, as the thin ink entering the sliding cavity 303 increases, the gravity force can make the driving plate 307 move downwards against the elastic force of the return spring 306, at this time, the discharging baffle 304 is pulled to move downwards together by the action of the connecting rod 305, at this time, the blocking of the discharging baffle 304 is omitted, the thickener storage box 3 drops thickener into the sliding cavity 303 through the conveying pipe 302, when the driving plate 307 moves downwards to the opening of the conveying inclined tube 215, the thickener flows into the ink discharging pipe 214 together with the thin ink entering the sliding cavity 303 through the conveying inclined tube 215, and is discharged out of the reciprocating member 2 through the ink discharging holes 203 together, and the phenomenon of pasting is avoided.
It should be noted that, specific model specifications of the motor need to be determined by selecting a model according to actual specifications of the device, and a specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
