Description

Technical Field

[0001] The present invention relates to a die-cutting machine, in particular to an automatic die-cutting machine with a simple structure and low production cost. Background Art

[0002] The die-cutting machine, also known as a beer machine, is mainly used for die-cutting indentation, hot stamping, laminating, and automatic waste discharging of some non-metallic materials, self-adhesive labels, EV first rotating shafts, double-sided tapes, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, metal molds, and steel wires to apply a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape. It is an important device for post-press packaging processing and forming. However, the existing die-cutting machines are generally semi-automatic. During the feeding process, manual feeding is usually adopted, and materials are manually sent into the die-cutting device, resulting in insufficient automation. Manual operation not only increases production costs and reduces production efficiency but also has certain risks. Moreover, on the existing die-cutting machines, a push shaft is usually arranged at the center of the top of the stamping table to drive the stamping table to perform reciprocating pushing actions on the materials on the workbench to achieve die-cutting. This pushing structure will cause a certain degree of position deviation of the stamping table during die-cutting, resulting in unstable die-cutting actions and uneven stress on the stamping table, leading to low finished product accuracy and being not conducive to production and use.

[0068] Further, the driving device 22 includes a driving motor, a second belt 18 wheel, a main transmission shaft 69, a first-stage secondary transmission shaft 70, and a plurality of second-stage secondary transmission shafts 71. The main transmission shaft 69, the first-stage secondary transmission shaft 70, and the plurality of second-stage secondary transmission shafts 71 are all arranged between two support plates 67, and both ends of each transmission shaft are rotatably mounted on the shaft holes 80 of the two support plates 67 through bearings 81. The driving motor is drivingly connected to the second belt 18 wheel to provide power, and the main transmission shaft 69 is drivingly connected to the second belt 18 wheel to transmit the power of the driving motor to the main transmission shaft 69 through the second belt 18 wheel. A driving wheel 72 is provided on the main transmission shaft 69, and a first driven wheel 73 meshing with the driving wheel 72 is provided on the first-stage secondary transmission shaft 70.

[0069] Further, the plurality of second-stage secondary transmission shafts 71 are preferably but not limited to two. The two second-stage secondary transmission shafts 71 are respectively arranged parallel to the two sides of the top of the first-stage secondary transmission shaft 70. Transmission components 9 are provided on both ends of the first-stage secondary transmission shaft 70 and the second-stage secondary transmission shafts 71 outside the two support plates 67. The transmission component 9 includes a second driven wheel 75 mounted on the first-stage secondary transmission shaft 70 and a third driven wheel 76 mounted on the second-stage secondary transmission shaft 71. The third driven wheels 76 on each second-stage secondary transmission shaft 71 are respectively meshed with the second driven wheel 75 to achieve driving connection. Moreover, an eccentric hole 77 is provided on one side of the axis of the third driven wheel 76, and the second rotating shaft 25 on the transmission arm 23 is mounted in the eccentric hole 77.

[0070] When die-cutting feeding is required, first, the second driving motor 28 is started. The second driving motor 28 drives the rotating shaft 29 to rotate through the speed reducer 30. During the rotation of the rotating shaft 29, the cams 31 at both ends thereof perform synchronous rotational motion. During the rotation of the cams 31, the lifting frame 10 is lifted or lowered by abutting against the rolling bearing 34 above it, so that the lifting frame 10 can perform cyclic lifting and lowering motions along with the rotation of the rotating shaft 29. Specifically, when the lifting frame 10 is lowered, the paper sheet is adsorbed by the suction device 11 on the lifting frame 10. Specifically, the first suction heads 46 and 47 on the first mounting rod 42 suck one side of the paper sheet tightly through the suction cups 93, and the third suction head 53 and the fourth suction head 54 on the second mounting rod 51 suck the other side of the paper sheet tightly through the suction cups 93. After the adsorption operation is completed, the lifting frame 10 is lifted under the drive of the cam 31, so that the first suction assembly 40 and the second suction assembly 41 suck the paper sheet in front of the pushing plate 16, thus completing a material taking operation.

[0071] Then, the first driving motor 12 starts, and the first driving motor 12 drives the first belt 18 wheel 13 to rotate, causing the gripper 57 on the pusher plate 16 to move to the paper sheet. At this time, the tensioning cylinder 62 on the pusher plate 16 starts, pushing out the push block 63. The push block 63 drives the ejector rod 64 to be pushed forward, causing the roller 97 at the front end of the ejector rod 64 to slide forward along the concave surface of the upper chuck 59, so that the upper chuck 59 rotates towards the lower chuck 58, and thus the pressure rod 60 at the front end of the upper chuck 59 presses down towards the lower chuck 58 to achieve the clamping operation of the paper sheet. Immediately afterwards, the first driving motor 12 drives the first belt 18 wheel 13 to rotate again. The belt 18 on the first belt 18 wheel 13 synchronously pulls the connecting block 15, causing the connecting block 15 to slide forward on the linear guide 14 through the second slider 48. Furthermore, the connecting block 15 drives the pusher plate 16 clamped with the paper sheet at its bottom to slide forward, sending the paper sheet from the material table 2 to the die-cutting station.

[0072] Next, when the paper sheet is sent to the designated die-cutting position, the tensioning cylinder 62 on the pusher plate 16 starts again, pulling the push block 63 back, causing the roller 97 at the front end of the ejector rod 64 to slide backward along the concave surface of the upper chuck 59 to the end of the upper chuck 59. At this time, the upper chuck 59 drives the pressure rod 60 to release the paper sheet on the lower chuck 58. After the paper sheet falls into the station, the first driving motor 12 starts again and drives the first belt 18 wheel 13 to rotate in the reverse direction, causing the belt 18 to pull the connecting block 15 back to the starting position, causing the connecting block 15 to slide backward on the linear guide 14 through the second slider 48. Furthermore, the connecting block 15 drives the pusher plate 16 to reset, thus completing one feeding action. By repeating the above steps, the cyclic feeding operation is achieved.

[0073] Secondly, during the continuous material taking process, the sprocket on the rack 1 drives the material table 2 to continuously rise, so that the materials in the material table 2 can always be kept at the optimal material taking position of the material taking device 7.

[0074] When die-cutting operation is required, when the driving motor starts, the second belt 18 wheel rotates under the drive of the driving motor, causing the second belt 18 wheel to drive the main transmission shaft 69 to perform synchronous rotational motion. When the main transmission shaft 69 performs rotational motion, the driving wheel 72 located on the main transmission shaft 69 rotates together with the main transmission shaft 69. The driving wheel 72 drives the first secondary transmission shaft 70 to perform synchronous rotation through the first driven wheel 73 meshing with it. At this time, the second driven wheels 75 at both ends of the first secondary transmission shaft 70 perform synchronous rotational motion, further driving the third driven wheel 76 located on the second secondary transmission shaft 71 to rotate, thus realizing the entire power transmission process.

[0075] Furthermore, during the rotation of the third driven wheel 76, the transmission arm 23 is driven by the second rotating shaft 25 to perform reciprocating up and down movements. At the same time, the transmission arm 23 drives the stamping table 21 to press down for die cutting or rise and release on the workbench 20 through the first rotating shaft 24. Since two transmission arms 23 are evenly distributed on both sides of the stamping table 21, the stamping table 21 is evenly stressed in all directions during die cutting, thereby realizing a stable die cutting operation.

[0076] Furthermore, after the die cutting operation is completed, the stamping table 21 rises from the workbench 20 under the action of the driving device 22 and the transmission arm 23. At this time, the drive on the material receiving mechanism 4 is started, and the material taking frame 90 moves forward along the sliding guide rail 89 to one side of the stamping table 21 under the drive, so that the fifth suction head 92 moves above the processed material. At the same time, the fifth suction head 92 sucks up the material under the drive of the lifting cylinder 94. After obtaining the material, the material taking frame 90 moves backward along the sliding guide rail 89 again under the drive, transports the obtained material to the material table 2, and finally, the fifth suction head 92 releases the material, causing the material to fall onto the material table 2 for collection, thus completing the material receiving operation.

[0077] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Those skilled in the art can make some deformations and modifications under the inspiration of this technical solution. Any modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
