[0031] In use, the dampening solution is added to the chamber of the dampening box 33 in advance, and the level of the dampening solution in the chamber of the dampening box 33 is kept above the bottom end of the outer surface of the sticky roller 3. The driving device 32 in the device is controlled by the control unit to operate. In operation, the motorized printing roller 1 is in a continuous rolling state, and the driving device 32 drives the sticky roller 3 to roll. The outer surface of the sticky roller 3 uniformly dips the dampening solution in the dampening box 33 in the rolling process. At this time, the sponge layer 21 of the outer surface of the coating roller 2 in close contact with the sticky roller 3 absorbs the dampening solution on the sticky roller 3. During this period, the sticky roller 3 drives the coating roller 2 to roll when rolling, so that the sponge layer 21 of the outer surface of the coating roller 2 can absorb the dampening solution, and the sponge layer 21 of the outer surface of the coating roller 2 is in close contact with the motorized printing roller 1. At the same time, the coating roller 2 is driven to reciprocate along the two ends of the sticky roller 3 by the operation of the translation mechanism 4, so that the dampening solution absorbed on the sponge layer 21 can be uniformly coated on the motorized printing roller 1 following the rolling state of the coating roller 2.

[0034] The transmission rod 43 is provided with a reciprocating thread 46, so that the overall structure of the transmission rod 43 is similar to the reciprocating screw structure, the bottom of the sliding block 42 is fixedly provided with a clamping block 47, the clamping block 47 is provided with a cylindrical groove 471 penetrating through both ends of the clamping block 47, the inner diameter of the cylindrical groove 471 is greater than the outer diameter of the transmission rod 43, the cylindrical groove 471 part of the clamping block 47 is sleeved on the transmission rod 43, the top of the clamping block 47 is rotatably provided with a clamping block 48, the bottom of the clamping block 48 extends into the cylindrical groove 471 from the top of the clamping block 47, the top of the clamping block 48 is fixedly provided with a guide strip 49, the bottom end of the guide strip 49 is provided with a slope on both sides, so that the bottom end of the guide strip 49 forms an inverted triangle with rounded corners in cross section, and the bottom end of the guide strip 49 is located in the reciprocating thread 46 area on the transmission rod 43;

[0035] The transmission mechanism 5 is provided on the outer side of the support 31 opposite to the driving device 32 on the viscose roller 3, the transmission mechanism 5 comprises a first transmission wheel 51, a second transmission wheel 52 and a transmission belt 53, the center part of the first transmission wheel 51 is fixedly connected with the side end center of the viscose roller 3 through a connecting shaft penetrating through the corresponding support 31, the second transmission wheel 52 is located at the side end of the translation bin 41, one end of the transmission rod 43 corresponding to the second transmission wheel 52 penetrates through the translation bin 41 and is fixedly connected with the center part of the second transmission wheel 52, and the transmission belt 53 is sleeved on the first transmission wheel 51 and the second transmission wheel 52, so that when the first transmission wheel 51 is driven to rotate, the second transmission wheel 52 can be driven to rotate synchronously under the action of the transmission belt 53;

[0036] With the rolling operation of the viscose roller 3, the first transmission wheel 51 will rotate, and the second transmission wheel 52 will keep synchronous rotation with the first transmission wheel 51 under the action of the transmission belt 53, so as to drive the transmission rod 43 in the translation bin 41 to rotate, so that the transmission rod 43 in the translation mechanism 4 can form synchronous operation with the viscose roller 3 without setting a separate driving device 32, which can effectively reduce the number of driving devices 32 in actual application, thereby reducing energy consumption;

[0037] During the rotation of the transmission rod 43, the reciprocating thread 46 area on the transmission rod 43 will implement traction to the bottom end of the guide strip 49, so that the guide strip 49 can drive the clamping block 48, the clamping block 47 and the sliding block 42 to move on the translation bin 41 in a reciprocating screw driver operation mode. When the guide strip 49 is moved to the leftmost end of the reciprocating thread 46 area along the traction of one of the thread lines in the reciprocating thread 46 area on the transmission rod 43, the continuous rotation of the transmission rod 43 will cause the other thread line connected with the thread line to implement butt joint traction to the guide strip 49, so that the guide strip 49 can drive the clamping block 48 to rotate at a certain angle, until the guide strip 49 can be switched to the other thread line in the reciprocating thread 46 area on the transmission rod 43, and follow the thread track of the thread line to drive the clamping block 48, the clamping block 47 and the sliding block 42 to move reversely on the translation bin 41. During this period, the reciprocating thread 46 arranged on the transmission rod 43 can drive the guide strip 49 to move in a reciprocating screw driver operation mode, so that the corresponding sliding block 42 and the coating roller 2 can move back and forth towards the two ends of the adhesive roller 3, so as to make the coating roller 2 roll along with the adhesive roller 3 and drive the sponge layer 21 to roll and move back and forth on the outer surface of the motorized printing roller 1 to coat the dampening solution, so that the outer surface of the motorized printing roller 1 can be uniformly attached with the dampening solution.

[0038] In a further preferred embodiment, a receiving bin 22 is arranged between the lower side of the coating roller 2 and the sliding block 42, the receiving bin 22 is internally provided with a chamber penetrating through the top thereof, the dampening bin 33 is provided with a water pump 6 below, and the receiving bin 22 and the dampening bin 33 are respectively provided with a drain hose 61, one end of each drain hose 61 is respectively communicated to the internal chamber of the corresponding dampening bin 33 and receiving bin 22, wherein the other end of the drain hose 61 on the dampening bin 33 is communicated to the water outlet port of the water pump 6, and the other end of the drain hose 61 on the receiving bin 22 is communicated to the water inlet port of the water pump 6.

[0039] When the sponge layer 21 of the coating roller 2 contacts and absorbs the dampening solution from the adhesive roller 3, part of the dampening solution will drip from the bottom end of the sponge layer 21 under the action of gravity. Therefore, the receiving bin 22 is arranged below the coating roller 2, so that the chamber of the receiving bin 22 can collect the dripping dampening solution on the sponge layer 21. In order to prevent the dampening solution in the chamber of the receiving bin 22 from overflowing, the water pump 6 can be operated to retransport the collected dampening solution in the receiving bin 22 to the chamber of the dampening bin 33 through the drain hose 61, so as to prevent the dampening solution in the chamber of the receiving bin 22 from overflowing for subsequent use.
