Description

Technical Field

[0001] This utility model relates to a die-cutting machine, specifically to a movable tooth guide rail device for the waste removal mechanism of a die-cutting machine. Background Technology

[0002] A die-cutting machine is a specialized piece of equipment for post-printing paper processing. One type of die-cutting machine is equipped with a waste removal mechanism to remove waste from the die-cut paper and obtain the desired shape. This mechanism mainly includes an upper waste removal plate, a middle waste removal plate, and a lower waste removal plate. The upper and lower waste removal plates are equipped with waste removal ejector pins, and the middle waste removal plate has clearance grooves for these pins to pass through. During operation, the middle waste removal plate is first lowered to allow the chain to drive the paper feeder and paper to the middle plate. Then, the middle plate is raised to the desired height, and the upper and lower waste removal plates are moved to perform waste removal. The drawbacks of this structure are: the middle waste removal plate needs to be a lifting mechanism. After a certain amount of paper is fed onto the middle plate and stacked, the plate needs to be raised. During this raising process, the paper stack may become loose and shift, affecting the subsequent waste removal accuracy. Additionally, the chain may deform over time, causing sagging and affecting the paper feeding accuracy. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a movable tooth guide rail device for the waste removal mechanism of a die-cutting machine to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A movable tooth bar guide rail device for the waste removal mechanism of a die-cutting machine is characterized by: including a first guide rail and a second guide rail corresponding to the left and right sides of the waste removal mechanism; a chain for connecting the tooth bar can pass through the guide grooves on the first and second guide rails; a waste removal plate is located between the first and second guide rails; one end of the first and second guide rails is hinged to the machine frame; the first and second guide rails are connected to a swing drive assembly; when the chain drives the tooth bar to move into the waste removal mechanism, the swing drive assembly drives the first and second guide rails to swing upward, so that the tooth bar and the waste removal plate are staggered vertically for conveying.

[0006] The swing drive assembly includes a drive shaft connected to one end of a first transmission arm. The other end of the first transmission arm is hinged to one end of a first transmission rod. The other end of the first transmission rod is hinged to one end of a second transmission arm. The other end of the second transmission arm is connected to a drive shaft. The drive shaft is connected to one end of a third transmission arm. The other end of the third transmission arm is hinged to one end of a second transmission rod. The other end of the second transmission rod is hinged to a lifting seat. A guide assembly is provided corresponding to the lifting seat. The other end of the lifting seat is hinged to the first and second guide rails.

[0007] The guide assembly includes a slide connected to the lifting seat, and a slide rail that mates with the slide is provided on the frame.

[0008] One end of the first guide rail is hinged to one end of the first swing arm, and the other end of the first swing arm is hinged to the frame. One end of the second guide rail is hinged to one end of the second swing arm, and the other end of the second swing arm is hinged to the frame.

[0009] The movable tooth bar guide rail device of the die-cutting machine waste removal mechanism described above, by setting the first and second guide rails, can guide the movement of the chain, replacing the traditional suspended conveying method of the chain. This avoids the chain from sagging after long-term use. At the same time, when the chain drives the tooth bar to move into the waste removal mechanism, the swing drive component can drive the first and second guide rails to swing upward, so that the tooth bar and the waste removal plate are staggered for conveying. By controlling the lifting of the chain and the tooth bar, the staggered separation from the waste removal plate is achieved, replacing the traditional method of lifting and staggering the waste removal plate. This eliminates the need for the waste removal plate to lift and lower the paper stack, thus preventing the paper stack from shifting or scattering, and ensuring that subsequent waste removal operations can be carried out stably.

[0013] Figure 3 for Figure 1 View after removing the waste removal plate;

[0014] Figure 4 for Figure 3 A magnified view of the area pointed to by B. Detailed Implementation

[0015] As shown in the figure, the movable tooth bar guide rail device of the waste removal mechanism of the die-cutting machine disclosed in this utility model includes a first guide rail 2 and a second guide rail 3 arranged on the left and right sides of the waste removal mechanism. The chain used to connect the tooth bar can pass through the guide groove 10 on the first and second guide rails. The waste removal plate 1 is located between the first and second guide rails. One end of the first and second guide rails is hinged to the machine frame. The first and second guide rails are connected to the swing drive component. When the chain drives the tooth bar to move into the waste removal mechanism, the swing drive component drives the first and second guide rails to swing upward, so that the tooth bar and the waste removal plate 1 are staggered vertically for conveying.

[0016] Furthermore, the swing drive assembly includes a drive shaft 12, which is connected to a drive motor. One end of the drive shaft 12 is connected to a first transmission arm 14, and the other end of the first transmission arm 14 is hinged to one end of a first transmission rod 4. The other end of the first transmission rod 4 is hinged to one end of a second transmission arm 5, and the other end of the second transmission arm 5 is connected to a drive shaft 15. The drive shaft 15 is connected to one end of a third transmission arm 6, and the other end of the third transmission arm 6 is hinged to one end of a second transmission rod 7. The other end of the second transmission rod 7 is hinged to a lifting seat 11. A guide assembly is provided corresponding to the lifting seat 11, and the other ends of the lifting seat 11 are hinged to the first and second guide rails. Using this structure, by controlling the rotation of the drive shaft 12, and then transmitting power through the transmission arm, transmission rod, and drive shaft structure, the lifting seat 11 can be raised and lowered, thereby causing the first and second guide rails to swing up and down. Of course, in addition to the above structure, common linear drive mechanisms such as cylinders and linear motors can also be used to drive the lifting seat 11 to rise and fall.

[0017] Furthermore, the guiding assembly includes a slide 9 connected to the lifting seat 11, and a slide rail 8 that mates with the slide 9 is provided on the frame. This structure ensures guidance for the lifting of the lifting seat 11.

[0018] Furthermore, one end of the first guide rail 2 is hinged to one end of the first swing arm 13, and the other end of the first swing arm 13 is hinged to the frame. One end of the second guide rail 3 is hinged to one end of the second swing arm, and the other end of the second swing arm is hinged to the frame. With this structure, it can be ensured that when the lifting seat 11 drives the first and second guide rails to swing, the first and second guide rails can swing smoothly up and down without jamming.

[0019] The working principle of this utility model is as follows: the chain passes through the guide grooves 10 of the first and second guide rails. When the teeth on the chain drive the paper to move into the waste removal mechanism, the swing drive component drives the first and second guide rails to swing upward, lifting and guiding the chain and teeth. This causes the fed teeth to be staggered with the waste removal plate 1 for paper conveying. After the paper is conveyed to the correct position, the teeth release the paper, allowing it to fall and stack on the waste removal plate 1 to await subsequent waste removal operations. At the same time, the first and second guide rails swing downward to reset, waiting for the next tooth conveyor to be used.
