[0002] A die-cutting machine is a device specially used for post-printing processing of paper. One type of die-cutting machine, after completing the die-cutting process, needs to pass the paper through a waste cleaning component to clean the paper. The traditional waste cleaning components mainly include an upper waste cleaning plate and a lower waste cleaning plate. The upper waste cleaning plate is fixed on the upper lifting seat, and the lower waste cleaning plate is fixed on the lower lifting seat. The upper and lower lifting seats are driven to move closer or farther from each other through the connecting rod assembly, thereby driving the upper and lower waste cleaning plates to move closer or farther from each other, thereby realizing the waste cleaning process. The defect of this structure is that the transmission mode of the connecting rod assembly causes the actual lifting stroke of the upper and lower lifting seats to be small, that is, when the upper and lower waste cleaning plates are in a separated state, the actual distance between the two is also small, resulting in insufficient operating space for the maintenance of the waste cleaning component, replacement of waste cleaning needles, etc. The entire upper lifting seat needs to be disassembled before the waste cleaning component can be repaired, the waste cleaning needles can be replaced, etc. Utility Model Content

[0017] As shown in the figure, the upper waste plate lifting and lowering driving mechanism of the die-cutting machine disclosed in the utility model comprises an upper lifting frame 1 and an upper waste plate 2. The upper lifting frame 1 is connected with a connecting rod transmission assembly to drive the upper lifting frame 1 to lift and lower. A guide seat 4 is arranged on the upper lifting frame 1, and a guide column 3 passing through the guide seat 4 is arranged on the frame to guide the lifting and lowering of the upper lifting frame 1. The connecting rod transmission assembly comprises a first connecting rod 7, one end of the first connecting rod 7 is hinged to the upper lifting frame 1, and the other end is connected to one end of a first L-shaped swing arm 6, the other end of the first L-shaped swing arm 6 is hinged to one end of a second connecting rod 20, the other end of the second connecting rod 20 is hinged to one end of a second L-shaped swing arm 10, the other end of the second L-shaped swing arm 10 is hinged to one end of a third swing arm 11, the other end of the third swing arm 11 is hinged to the upper lifting frame 1, and the first L-shaped swing arm 6 is connected to the first rotating shaft 5. By controlling the rotation of the first rotating shaft 5 and transmitting through the above-mentioned connecting rod assembly, the upper lifting frame 1 can be driven to lift and lower under the guidance of the guide column 3. The upper waste cleaning plate 2 can be placed on the upper lifting frame 1, and a positioning block 15 and a clamping claw assembly are provided on the upper waste cleaning plate 2. The upper lifting frame 1 is provided with a positioning groove 19 for inserting the positioning block 15. The clamping claw assembly can be clamped on the upper lifting frame 1. Specifically, the clamping claw assembly includes a clamping claw seat 14 provided on the upper waste cleaning plate 2, and a clamping claw 17 is swingably provided on the clamping claw seat 14. A spring 16 is connected between the clamping claw 17 and the clamping claw seat 14. The outer side of the clamping claw 17 is provided with an arc surface 21 that can contact and squeeze the upper lifting frame 1. When the upper waste cleaning plate 2 is lowered to the upper lifting frame alone, the upper waste cleaning plate 2 can be lifted and lowered. When the lowering frame 1 is raised, the arc surface 21 on the clamping jaw 17 first contacts and squeezes the upper lifting frame 1, driving the clamping jaw 17 to swing and stretching the spring 16 at the same time. Then, the upper waste cleaning board 2 continues to descend and rests on the upper lifting frame 1. At this time, when the clamping jaw 17 just moves to the clamping groove 18 on the upper lifting frame 1, the spring 16 squeezes the clamping jaw 17 to swing, driving the clamping jaw 17 to insert into the clamping groove 18, so as to achieve the clamping positioning between the upper lifting frame 1 and the upper waste cleaning board 2. When the upper waste cleaning board 2 rises, the clamping jaw 17 will be squeezed and swung out of the clamping groove 18. The upper waste cleaning board 2 is connected to one end of the chain 12, the chain 12 bypasses the sprocket, and the other end of the chain 12 is connected to the transmission wheel 13, and the transmission wheel 13 is connected to the driving motor 8. Specifically, the output end of the driving motor 8 is connected to the gear set, the output wheel of the gear set is connected to the rotating shaft 9, and the transmission wheel 13 is connected to the rotating shaft 9. Four chains 12 are provided, and are respectively connected to the four corners of the upper waste cleaning plate 2, so that the force on the upper waste cleaning plate 2 is more balanced, ensuring that the upper waste cleaning plate 2 can be stably lifted and lowered.

[0018] The working principle of the utility model is as follows: when the waste cleaning operation is normally carried out, the transmission wheel 13 is controlled to rotate to reduce the winding of the chain 12 on the transmission wheel 13. At this time, the upper waste cleaning plate 2 will naturally fall and abut on the upper lifting frame 1. At the same time, the positioning block 15 is inserted into the positioning groove 19, and the clamping claw 17 is positioned and clamped in the clamping groove 18 on the upper lifting frame 1 to realize the positioning of the upper waste cleaning plate 2 on the upper lifting frame 1. At this time, as the transmission wheel 13 continues to rotate, the chain 12 is in a loose state, and then the connecting rod assembly drives The upper lifting frame 1 and the upper waste cleaning plate 2 descend to cooperate with the lower waste cleaning plate to perform waste cleaning operations, and the loose chain 12 will not interfere with the descent of the upper waste cleaning plate 2; when it is necessary to control the upper waste cleaning plate 2 to rise alone to make room, the transmission wheel 13 is controlled to reverse, driving one end of the chain 12 to continuously wrap around the transmission wheel 13. At this time, the other end of the chain 12 will drive the upper waste cleaning plate 2 to be pulled upward alone, making more operating space so that maintenance, replacement of the upper waste cleaning needle and other operations can be carried out at the waste cleaning component.

[0019] The structure of the utility model, by separately arranging the upper waste cleaning plate and the upper lifting frame, can not only place the upper waste cleaning plate on the upper lifting frame and lift it with the upper lifting frame to cooperate in the waste cleaning operation, but also drive the upper waste cleaning plate to be lifted and lowered separately through the chain mechanism, so that the upper waste cleaning plate can be lifted to a higher height, thereby making more operating space available for maintenance at the waste cleaning component, replacement of the upper waste cleaning needles, and the like.
