Technical Field

[0001] The utility model belongs to the technical field of die-cutting machines, and particularly relates to a cardboard buffering mechanism of a die-cutting machine. Background Technique

[0002] A die-cutting machine, also known as a beer machine, a cutting machine, and a numerical control stamping machine, is mainly used for die-cutting, indentation, hot stamping, lamination, and automatic waste discharging of some non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone gaskets, etc. The die-cutting machine uses steel knives, hardware molds, and steel wires to apply a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape.

[0003] Since the die-cutting machine will transfer the cardboard to the collection place through a conveyor belt after die-cutting the cardboard, and there will be a certain impact force when the cardboard is conveyed. However, the traditional buffering device lacks a buffering device on the side for docking the cardboard, which leads to the cardboard hitting the side plate, causing the cardboard to curl on one side, thus affecting the subsequent use of the cardboard.

A first spring 405 is sleeved on the outer wall of the first fixing rod 402. Limiting grooves 406 are opened on both sides of the inner wall of the placement groove 401, and limiting blocks 403 are slidably connected in the limiting grooves 406. One side of the limiting block 403 is connected to one side of the buffer plate 404. The placement groove 401 is opened on one side of the side baffle 1. The other end of the first fixing rod 402 is connected to one side of the inner wall of the placement groove 401, and both ends of the first spring 405 are respectively connected to one side of the buffer plate 404 and one side of the inner wall of the placement groove 401. A buffer pad is provided on one side of the buffer plate 404, and the buffer pad is made of soft rubber.

[0026] Specific implementation manner: By setting the buffer pad, since the buffer pad is made of soft rubber, when the cardboard contacts the buffer plate 404, through the preliminary buffering of the buffer pad, the cardboard and the buffer plate 404 are prevented from making hard contact, thereby ensuring the integrity of the cardboard. By setting the first fixing rod 402, supported by the first fixing rod 402, the first spring 405 is prevented from bending when compressed, and thus the resilience effect of the first spring 405 is ensured.

[0027] An inner groove 3 is provided in the side baffle 1, and an organizing device 6 is arranged in the inner groove 3. The organizing device 6 includes a protective box 604. A motor 606 is fixedly installed on one side of the protective box 604. The output shaft of the motor 606 extends into the protective box 604 and is connected with a driving wheel 601. Two driven wheels 605 are meshed with the outer wall of the driving wheel 601. A threaded rod 607 is connected to one side of the driven wheel 605. A threaded seat 602 is threadedly connected to the outer wall of the threaded rod 607. An organizing plate 603 is connected to one side of the threaded seat 602. One end of the threaded rod 607 extends out of the protective box 604, and one end of the threaded rod 607 is rotatably connected to one side of the inner wall of the inner groove 3. Both sides of the protective box 604 are respectively connected to both sides of the inner wall of the inner groove 3. The bottom of the organizing plate 603 is in contact with the top of the support box 2. A lifting device 5 is arranged in the support box 2. The lifting device 5 includes an electric push rod 504. A pressing block 505 is connected to the top rod of the electric push rod 504. A pressing frame 503 is attached to one side of the pressing block 505. A connecting plate 508 is connected to the top of the pressing frame 503. Fixing cylinders 506 are connected to both sides of the connecting plate 508. A second fixing rod 502 is slidably connected to the inner wall of the fixing cylinder 506. A second spring 501 is sleeved on the outer wall of the second fixing rod 502. A support plate 507 is connected to the top of the fixing cylinder 506. One side of the electric push rod 504 is fixedly installed on one side of the inner wall of the support box 2. The bottom of the second fixing rod 502 is connected to the bottom of the inner wall of the support box 2. Both ends of the second spring 501 are respectively connected to the bottom of the fixing cylinder 506 and the bottom of the inner wall of the support box 2. Two embedding grooves 7 are provided at the top of the support box 2. A connecting groove 8 is provided at the bottom of the embedding groove 7. The inner wall of the connecting groove 8 is slidably connected to the outer wall of the fixing cylinder 506. The inner wall of the embedding groove 7 is in contact with the outer wall of the support plate 507.

[0028] In the specific implementation manner, by setting the lifting device 5, the electric push rod 504 drives the pressing block 505 to move, so that the pressing block 505 presses the inner wall of the pressing frame 503, causing the pressing frame 503 to move upward. Then, the connecting plate 508 drives the fixing cylinder 506 to move upward, so that the fixing cylinder 506 drives the support plate 507 to move and the support plate 507 lifts the stack of cardboard sheets. As a result, a gap is generated between the lowermost cardboard sheet and the support box 2, which facilitates the packing and handling of the cardboard sheets, and further improves the convenience of subsequent collection of the cardboard sheets.

[0029] Working principle: When in use, the cardboard is conveyed to one side of the device, so that one side of the cardboard contacts the buffer plate 404, causing the buffer plate 404 to move inward and compress the first spring 405, making the first spring 405 contract to absorb the impact force, thereby preventing the cardboard from curling on one side and affecting subsequent use. After the cardboard conveying is completed, the motor 606 drives the driving wheel 601 to rotate, and then the driving wheel 601 drives the driven wheel 605 to rotate. The driven wheel 605 drives the threaded rod 607 to rotate, and then the threaded rod 607 drives the threaded seat 602 to move. The threaded seat 602 drives the sorting plate 603 to move and sort the cardboard. Then, the electric push rod 504 drives the extrusion block 505 to move, causing the extrusion block 505 to extrude the inner wall of the extrusion frame 503, making the extrusion frame 503 move upward, and then driving the connecting plate 508 to move upward. The support plate 507 is driven to move upward through the fixed cylinder 506, so that the support plate 507 lifts the cardboard stack, making the packing more convenient.
