Description

Technical Field

[0001] The utility model relates to paper punching and cutting equipment, in particular to a punching and cutting mechanism of a high-stability die-cutting machine. Background Art

[0002] The slitting machine is a device specially used for punching and cutting stacked papers. The structure of the slitting machine mainly includes a front blade and a punching knife. A knife groove corresponding to the shape of the punching knife is set on the front blade. When punching and cutting, the stacked papers are sent between the front blade and the punching knife, and then the punching knife is driven to move, squeezing the paper pile so that the finished paper of the required shape is pressed out of the knife groove to complete the slitting operation. The traditional punching knife is directly driven by a connecting rod mechanism, etc. In actual use, it is found that after long-term use, the position of each transmission component may be slightly offset, which causes the position of the punching knife to shift, resulting in the punching knife being unable to accurately cooperate with the knife groove for slitting, affecting the normal operation of the slitting machine.

[0006] It also includes a front connecting plate, one side of which is inserted into a slot on the frame and connected to the frame through fasteners. The front blade plate is connected to the front connecting plate through fasteners, and the front connecting plate has a clearance slot corresponding to the blade slot.

[0007] The front blade is provided with a first guide post, and the first guide post passes through a first guide sleeve on the rear blade.

[0008] A slide seat is arranged on the guide seat, and a slide rail matched with the slide seat is arranged on the frame.

[0009] The reciprocating driving assembly comprises a crankshaft and a transmission arm, one end of the transmission arm is sleeved on the crankshaft, and the other end is hinged to a rear connecting plate, and the rear connecting plate is fixed on a guide seat.

[0010] A second guide post is arranged on the frame, and the second guide post passes through a second guide sleeve on the rear connecting plate.

[0011] There are two crankshafts, and at least two transmission arms are connected to each crankshaft. A first gear is connected to one crankshaft, and a second gear meshing with the first gear is connected to the other crankshaft.

[0012] For the punching mechanism of the high-stability die-cutting machine with the above technical solution, by arranging the rear knife plate mounting the punching knife on the guide seat and sliding the guide seat on the frame, even if the position of the reciprocating movement driving component at the rear side has a certain deviation, due to the sliding structure of the guide seat, it can still ensure that the positions of the rear knife plate and the punching knife do not deviate, so that the punching knife can accurately cooperate with the knife groove on the front knife plate for slitting operation, ensuring the slitting quality.

[0016] Figure 3 is Figure 2 a view from the other side after removing a part of the frame. Detailed Embodiments

[0017] As shown in the figure, the punching mechanism of the high-stability die-cutting machine disclosed by the present utility model includes a front knife plate 3 fixed on a frame. A knife groove 2 is formed on the front knife plate 3. The punching mechanism further includes a punching knife 18, the shape of the punching knife 18 corresponding to that of the knife groove 2. The punching knife 18 is arranged on a rear knife plate 5, and the rear knife plate 5 is arranged on a guide seat 8. The guide seat 8 is slidably arranged on the frame, and the guide seat 8 is connected with a reciprocating movement driving assembly. Further, a front connecting plate 1 is included. One side of the front connecting plate 1 is inserted into a slot 17 on the frame 20 and is connected with the frame 20 through a fastener. The front knife plate 3 is connected to the front connecting plate 1 through a fastener. The front connecting plate 1 has a relief through groove 16 corresponding to the knife groove 2. By arranging the front connecting plate 1, the positioning installation and disassembly of the front knife plate 3 can be conveniently realized. A first guide post 6 is arranged on the front knife plate 3. The first guide post 6 passes through a first guide sleeve 4 on the rear knife plate 5, capable of guiding the movement of the rear knife plate 5 and further improving the stability of the movement of the rear knife plate 5.
