The working principle of the utility model is described below:

when the receiving part does not clear waste, namely the whole machined piece falls down to receive the waste, the paper pressing plate 107 is removed, the upper paper scraping plate 108 is installed, the bolt is loosened, the paper scraping plate seat 176 moves backwards to retract into the paper supporting plate 173, the air cylinder 6 works, the clutch swing arm 8 is pulled to the left side of the sliding seat 7, the clutch swing arm 8 swings with the upper pull rod 5 and the lower pull rod 9, the upper pull rod 5 and the lower pull rod 9 are approximately in the same straight line, when the air cylinder 6 acts, the upper pull rod 5 swings with the connecting arm 4, the first rotating shaft 3 rotates by an angle, the combined length of the upper pull rod 5 and the lower pull rod 9 is maximum, at the moment, after the cam 10 works, when the second rotating shaft 17 and the first rotating shaft 3 are rotated through the pull rod and the connecting rod, the second swing arm 171 on the second rotating shaft 3 is matched with the swing arm 24 on the gripper bar assembly through the bump block 172, so that the swing arm 24 swings, the rotating shaft 24 is reciprocally rotated, the opening and the occlusion of the gripper are realized, when the imprinted product is moved to the upper part of the material collecting part 13 by the gripper bar, the first gripper opening device performs the gripper opening action, meanwhile, the paper scraping cam 101 which is installed on the same cam shaft 103 with the cam 10 swings the paper scraping swing rod 106 through the paper scraping main shaft 105, and drives the paper scraping sheet 108 to swing, and the imprinted product is scraped to fall onto the material collecting part 13. After the first rotating shaft 3 rotates by an angle, the first swing arm 31 on the first rotating shaft 3 also rotates by an angle and is farther away from the swing arm 24, and after the cam 10 rotates, when the lower pull rod 9, the clutch swing arm 8 and the upper pull rod 5 swing with the connecting arm 4, the first swing arm 31 on the first rotating shaft 3 cannot be matched with the swing arm 24 on the rotating shaft 23, so that the secondary tooth opening action is in a failure state.

When waste cleaning is needed, namely, the stamped product is transferred to the position above the material collecting part 13, the finished product is cut off through the cooperation of the paper pressing plate 107 and the paper scraping plate seat 176, and the waste edges clamped by the gripper clamp are left. Therefore, the paper scraping sheet 108 needs to be removed first to replace the paper pressing plate 107, and the bolt is loosened, so that the paper scraping sheet 176 is moved leftwards, that is, the paper scraping sheet is exposed out of the paper supporting sheet 173 to be matched with the paper pressing plate 107, and the bump 172 on the second swing arm 171 is removed, so that after the second swing arm 171 swings, the second swing arm 171 is insufficient to be matched with the swing arm 24; at the same time, the cylinder 6 acts to push the clutch swing arm 8 to the right of the slide 7, so that the length of the combined upper pull rod 5 and lower link 9 becomes shortest, i.e. the first swing arm 31 swings an angle in the opposite direction to the above, and the first swing arm 31 rotates with the first rotating shaft 3, and the first swing arm 31 also rotates an angle, so that the combined swing arm can cooperate with the swing arm 24. The paper scraping cam 101 swings the paper scraping swing arm 102 to enable the paper scraping main shaft 105 to swing with the paper scraping swing arm 106, the paper pressing plate 107 swings to be matched with the paper scraping plate seat 176, a finished product is cut off and falls down to the material collecting part 13, and the remained slitter edges are clamped by the gripper, because the second swing arm 171 swings and cannot be matched with the swing arm 24 on the rotating shaft 23, the first gripper device is in a failure state, namely the gripper is still clamped by the gripper to continuously convey the slitter edges under the transmission of a chain, when the slitter edges are transmitted to the upper side of the die cutting thermoprinting machine by the gripper bar assembly 2, the second gripper device acts, namely the swing of the first swing arm 31 is matched with the swing arm 24 on the gripper bar assembly 2 transmitted to the position, so that the opening and closing action of the gripper is realized, and under the matching of the paper scraping plate 14, the slitter edges are conveyed out by the conveying belt 15 on the conveying belt 15 below the first rotating shaft 3.

In the above embodiments, the description of the directivity is as to the direction according to the drawing.
