[0035] A specific application of this embodiment is: the present invention is an electric pad printing machine. When in use, the controller 10 controls the motor 44 to drive the transmission shaft 43 to rotate, which can simultaneously drive the first cam 45 and the second cam 49 to rotate, so as to realize the pad printing action of the rubber head 6. The specific movement actions are:

[0036] Assume that the initial position is that the first cam 45 is at the minimum stroke, that is, the rotation axis of the first cam 45 is closest to the first follower wheel 47, the entire transverse slider 33 and its connecting parts are at the frontmost position, and the second cam 49 is at the return motion angle, that is, the rotation axis of the second cam 49 is farthest from the second follower wheel 482 abutting against it; the rollers 810 on the two sets of roller frames 89 do not touch the tool lifting guide rail 86 and the tool retracting guide rail 87, and the scraper 83 and the oil roller 843 are close to the pad printing steel plate.

[0037] The first cam 45 enters the lifting motion angle, the second cam 49 moves to the rest angle, the rubber head 6 stops moving upward, and the transverse slider 33 moves horizontally backward, driving the rubber head 6, the scraper 83, and the oil roller 843 to move backward together. The scraper 83 is close to the pad printing steel plate 73 in the pad printing oil pan 7 to scrape the ink on the pad printing steel plate 73. After the entire transverse slider 33 and its connecting parts move backward to a certain stroke, the roller 810 on the rear roller frame 89 overcomes the elastic force of the third spring 811 and rotates clockwise to close to the retracting guide rail 87. After the horizontal hollow plate 88 moves a certain distance, the roller 810 on the front roller frame 89 touches the lifting guide rail 86, causing the horizontal hollow plate 88 and the vertical slide rod 81 to move vertically upward, the scraper 83 and the pad printing steel plate 73 are separated, and the scraper 83 lifts the knife upward.

[0038] The first cam 45 enters the maximum stroke, i.e., the far rest angle, and the entire transverse sliding block 33 and its connecting parts do not make lateral movement at the rearmost position. The second cam 49 first enters the lifting movement angle, and the rubber head 6 moves longitudinally downward to the lowest point, touches the pad printing steel plate 73, and transfers the text or pattern on the pad printing steel plate 73 to the rubber head 6. Then, the second cam 49 enters the return movement angle, and the rubber head 6 separates from the pad printing steel plate 73 and moves longitudinally upward to the highest position. The roller 810 on the front roller frame 89 is still in contact with the knife lifting guide rail 86, and the scraper 83 is still lifting the knife upward. The roller 810 on the rear roller frame 89 withdraws from the knife retracting guide rail 87 and rotates counterclockwise to a certain angle under the action of its third spring 811.

[0039] The first cam 45 enters the return motion angle, and the entire transverse sliding block 33 and its connecting parts move forward, driving the rubber head 6, the scraper 83, and the oil roller 843 to move forward together. The second cam 49 moves to the rest angle, and the rubber head 6 remains at the highest position of the stroke. After the entire transverse sliding block 33 and its connecting parts move forward to a certain stroke, the roller 810 on the rear roller frame 89 touches the knife retracting guide rail 87, and the roller 810 on the front roller frame 89 still touches the knife lifting guide rail 86 and moves forward for a certain stroke. Then, the roller 810 on the front roller frame 89 is separated from the knife lifting guide rail 86, and the roller 810 on the rear roller frame 89 still touches the knife retracting guide rail 87 and moves to the left. The scraper 83 is still in the knife lifting state, but the oil roller 843 is close to the pad printing steel plate under the action of gravity, and rolls the ink onto the pad printing steel plate.

[0040] The first cam 45 enters the near-rest angle, the entire transverse sliding block 33 and its connecting parts return to the frontmost position without lateral movement, the second cam 49 first enters the lifting movement angle, the rubber head 6 moves downward to the lowest point, and the text or pattern on the steel plate is transferred to the product fixed on the workpiece fixing table 9. Then, the second cam 49 enters the return movement angle, the rubber head 6 separates from the product and moves upward, the roller 810 on the rear roller frame 89 separates from the retracting guide rail 87, and the scraper 83 is close to the pad printing steel plate.

[0041] The motor 44 drives the transmission shaft 43 to rotate and circulate according to the above steps.
