Before cleaning, the liquid level of the solution added in the water tank 1 is lower than the horizontal part at the bottom of the driving rod 30, then the motor 12 is started, the motor 12 drives the first conveyor belt 10 to rotate clockwise, the second conveyor belt 11 rotates anticlockwise, then the sheet to be cleaned is placed in a discharging group, the discharging group intermittently conveys the sheet to be cleaned to two conveying groups at the front side and the rear side, and the conveying groups at the front side and the rear side are respectively clamped from the front side and the rear side of the sheet and then are conveyed;
The working process of the conveying group is as follows:
When the first and second connection bars 14 and 23 are moved to the rightmost sides of the first and second conveyor belts 10 and 11, the discharging group horizontally places the sheet to be cleaned to the middle positions of the first and second connection bars 14 and 23, the first and second clamping blocks 19 and 27 are contacted with the sheet to be cleaned from the upper and lower sides respectively as the first and second conveyor belts 10 and 11 are rotated, and at this time, the first and second connection bars 14 and 23 are inclined, the discharging group keeps the sheet to be cleaned horizontal while contacting, at this time, the first and second clamping blocks 19 and 27 are rotated around the rotation axes of the contact bar 18 and the connection block 25, respectively, and the protruding ends of the contact bar 18 and the connection block 25 are slid inside the first and second arc grooves 20 and 28 respectively, the fourth spring 21 and the seventh spring 29 are compressed to facilitate the clamping of the first clamping block 19 and the second clamping block 27 to the sheet, then the first connecting rod 14 and the second connecting rod 23 continue to rotate along with the rotation of the first conveyor belt 10 and the second conveyor belt 11, so that the first clamping block 19 and the second clamping block 27 clamp the sheet, but the sheet cannot move up and down, so that the first clamping block 19 and the second clamping block 27 are all resisted when the first connecting rod 14 and the second connecting rod 23 continue to rotate, then the first clamping block 19 has a tendency to drive the contact rod 18 to slide up along the first connecting rod 14, but the third spring 17 cannot compress, but the second clamping block 27 drives the connecting rod 25 to slide along the second connecting rod 23 and compress the sixth spring 26, the first clamping block 19 and the second clamping block 27 clamp the sheet and drive the sheet to move horizontally;
When the seventh spring 29 is reset when the first connecting rod 14 and the second connecting rod 23 are in the vertical state, the first clamping block 19 and the second clamping block 27 are also in the initial state, but when the sixth spring 26 is compressed in a certain state, the sheet material moves leftwards horizontally along the first clamping block 19 and the second clamping block 27, after a certain distance of movement, the contact rod 18 is contacted with an inclined part on the right side of the driving rod 30, the driving rod 30 gradually descends to contact the contact rod 18 while moving, the contact rod 18 slides downwards along the first connecting rod 14 and stretches the third spring 17, the second clamping block 27 drives the connecting block 25 to slide downwards along the second connecting rod 23, the sixth spring 26 is compressed again, the first clamping block 19 and the second clamping block 27 and the clamped sheet material submerge after the contact rod 18 moves to the horizontal position at the bottom of the driving rod 30, and then the sheet material moves in water along with the rotation of the motor 12, and the sheet material is cleaned;
After the contact rod 18 moves from the bottom of the horizontal part of the driving rod 30 to the bottom of the horizontal part of the left side of the driving rod 30, the pressure exerted by the contact rod 18 and the third spring 17 is released to a certain extent, at the moment, the contact rod 18 rises to the initial position of the first connecting rod 14, at the moment, the connecting rod 25 and the sixth spring 26 rise to a certain distance, at the moment, the sheet rises to a position higher than the liquid level from the water, then continues to move towards the placing frame 2, after the contact rod 18 moves to the left side of the driving rod 30, the cam 8 lifts the round rod 7 to enable the round rod 7 to be in contact with the circular arc surface of the cam 8, at the moment, the lifting frame 3 and the pushing block 4 push the washed sheet on the placing frame 2 to rise, and at the moment, the round rod 7 contacts with the circular arc surface of the cam 8, the washed sheet still keeps a state of being separated from the placing frame 2, at the moment, the leftmost end of the sheet clamped by the first clamping block 19 and the second clamping block 27 enters a part on the placing frame 2, and the distance between the inner walls of the two placing frames 2 is just or slightly larger than the width of the sheet;
Then, the side walls of the first connecting rod 14 and the second connecting rod 23 will contact with the tail ends (i.e. the right ends) of the two push rods 32 respectively at this time, and the first connecting rod 14 and the second connecting rod 23 will contact with the middle inclined transition surface of the push rod 32 and move along the transition surface when continuing to move leftwards, so that the first connecting rod 14 and the second connecting rod 23 slide along the first limit post 13 and the second limit post 22 respectively, at this time, the second spring 15 and the fifth spring 24 will be gradually compressed, at this time, the first connecting rod 14 and the second connecting rod 23 will gradually move away from the placing frame 2 while moving leftwards, but at this time, the sheet clamped by the first clamping block 19 and the second clamping block 27 will also enter a large part of the interior of the placing frame 2, and when the first connecting rod 14 and the second connecting rod 23 move away from the placing frame 2, the large part of the sheet is located between the two placing frames 2, so that when the first connecting rod 14 and the second connecting rod 23 move away from the placing frame 2, the first clamping block 19 and the second clamping block 27 will gradually separate from the sheet, but will not be limited by the front side of the placing frame 2;
The distance between the first clamping block 19 and the second clamping block 27, which are positioned at the front and back after the first connecting rod 14 and the second connecting rod 23 pass through the inclined transition surface of the push rod 32, is the maximum distance, and is the front and back of the placement frame 2, at the moment, when the first connecting rod 14 and the second connecting rod 23 continue to move leftwards, the contact with the placement frame 2 can be avoided, then the first connecting rod 14 and the second connecting rod 23 can move to the position contacted with the limiting rod 31, the limiting rod 31 is in the shape of an arc, the first connecting rod 14 and the second connecting rod 23 can be ensured to rotate when the first connecting rod 14 and the second connecting rod 23 move to the left side of the placement frame 2, so that the contact is avoided, and when the first connecting rod 14 and the second connecting rod 23 are separated from the limiting rod 31, the second spring 15 and the fifth spring 24 can push the first connecting rod 14 and the second connecting rod 23 to reset;
