[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a fully automatic die-cutting machine, including a frame 1 and a moving platform mechanism 2. The moving platform mechanism 2 is fixedly installed on the top of the outer wall of the frame 1. The moving platform mechanism 2 includes a support plate 3 and a guide column 4. The guide column 4 is fixedly installed on the top of the outer wall of the frame 1. The lower end of the guide column 4 is fixedly connected to the support plate 3. The support plate 3 contacts a driven roller 6. The driven roller 6 contacts the outer contour of a cam 7. The driven roller 6 drives the support plate 3 to reciprocate up and down along the axial direction of the guide column 4.

[0029] Specifically, the servo motor is started, and the power output by the servo motor is reduced by the reducer and drives the transmission shaft of the cam 7 to rotate. The transmission shaft drives the cam 7 to rotate synchronously through the flat key. The rotation of the cam 7 pushes the driven roller 6 to move up and down along the radial direction of the cam 7. Since the driven roller 6 is fixed on the support plate 3 through the bearing seat, the movement of the driven roller 6 directly drives the support plate 3 to move up and down along the axial direction of the guide column 4.

[0030] The reciprocating motion of the support plate 3 drives the die-cutting blade to move synchronously. When the support plate 3 moves downward, the die-cutting blade contacts the material to be processed, completing the die-cutting operation; when the support plate 3 moves upward, the die-cutting blade separates from the material. The support plate 3 and the guide post 4 are connected by a linear bearing. The support plate 3 has a ball bearing cage inside, which converts sliding friction into rolling friction, ensuring smooth and uninterrupted movement of the support plate 3 along the axial direction of the guide post 4. The driven roller 6 and the cam 7 form a transmission pair, which is the power source for driving the reciprocating motion of the support plate 3.

[0031] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a fully automatic die-cutting machine, wherein one end of the support plate 3 is hinged to a connecting rod 8, the connecting rod 8 is hinged to a swing rod 9, the swing rod 9 is hinged to the top of the outer wall of the frame 1, and a driven roller 6 is fixedly installed in the middle of the swing rod 9;

[0032] An adjustment groove 10 is provided on the outer wall of the swing arm 9. A locking bolt 11 is inserted in the middle of the adjustment groove 10. A fixing block 12 is fixedly installed at the end of the swing arm 9. The outer wall of the fixing block 12 is fixedly connected to the shaft of the driven roller 6. The fixing block 12 drives the driven roller 6 to move.

[0033] Specifically, the servo motor starts, and the power is reduced by the reducer to drive the cam 7 to rotate; the contour curve of the cam 7 pushes the driven roller 6 to move up and down, and the driven roller 6 drives the rocker arm 9 to swing around the hinge fulcrum in the middle through the fixed block 12; the swing of the rocker arm 9 causes its upper end to make an arc motion, and the swing is converted into the support plate 3 moving linearly along the axis of the guide post 4 through the connecting rod 8; the support plate 3 drives the die-cutting blade to move up and down reciprocally.

[0034] To increase the die-cutting stroke, move the swing arm 9 away from the fulcrum. This increases the lever arm of the swing arm 9 (the distance from the driven roller 6 to the fulcrum). According to the lever principle, when the swing angle of the swing arm 9 remains unchanged, the displacement of its upper end increases, which in turn increases the stroke of the support plate 3 via the connecting rod 8. To decrease the die-cutting stroke, move the swing arm 9 closer to the fulcrum. This decreases the lever arm of the swing arm 9 and reduces the stroke of the support plate 3. After adjusting to the target stroke, tighten the locking bolt 11 to fix the position of the swing arm 9. Stroke adjustment does not require replacing transmission components; it can be completed simply by loosening the locking bolt and moving the swing arm, significantly improving equipment switching efficiency.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a fully automatic die-cutting machine, wherein a limiting block 14 is fixedly installed at the end of the outer wall of the guide column 4, and a buffer spring 13 is sleeved on the outer wall of the guide column 4; one end of the buffer spring 13 abuts against the support plate 3, and the other end abuts against the limiting block 14; a negative pressure adsorption hole 15 penetrates the outer wall of the support plate 3, the negative pressure adsorption hole 15 adsorbs the die-cutting blade plate 16, a pressure plate 17 is detachably installed at the top of the outer wall of the die-cutting blade plate 16, a positioning pin 18 is fixedly installed at the bottom of the outer wall of the pressure plate 17, and a magnetic block 19 is fixedly installed at the bottom of the outer wall of the positioning pin 18.

[0036] Specifically, when the support plate 3 moves upward, the upper end face of the support plate 3 presses against the buffer spring 13, causing the spring to compress and deform, converting the kinetic energy of the support plate 3 into the elastic potential energy of the spring, thereby reducing the upward speed of the support plate 3 and reducing the impact with the limiting block 14.

[0037] When the support plate 3 moves downward, the buffer spring 13 gradually recovers its deformation, releases elastic potential energy, and provides downward auxiliary force for the support plate 3, making the movement of the support plate 3 more stable. At the same time, it reduces the impact when the die-cutting blade 16 comes into contact with the material, and avoids rough edges when the material is cut.

[0038] The function of the negative pressure suction hole 15 is to use negative pressure suction to adhere the die-cutting blade 16 to the support plate 3, thus achieving initial fixation. Start the negative pressure pump and place the die-cutting blade 16 on the upper end face of the support plate 3, so that the positioning hole of the die-cutting blade 16 is roughly aligned with the positioning pin 18 of the pressure plate 17;

[0039] The positioning pin 18 of the pressure plate 17 is aligned with the positioning hole of the die-cutting blade plate 16 and inserted. The magnetic block 19 at the lower end of the positioning pin 18 attracts the die-cutting blade plate 16 for precise positioning. At the same time, the negative pressure pump is started, and the negative pressure suction hole 15 generates suction to attract the die-cutting blade plate 16 onto the support plate 3.

[0040] Turn off the negative pressure pump, lift the pressure plate 17 upwards to separate the positioning pin 18 from the positioning hole of the die-cutting blade 16, and the suction force will disappear. Then remove the die-cutting blade 16 from the support plate 3.

[0041] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a fully automatic die-cutting machine. A fixed fulcrum is provided on the outer wall of the support plate 3. The fixed fulcrum is hinged to a lever 22, which is hinged to a traction rod 23. The traction rod 23 is hinged to a positioning baffle 20. A slider is fixedly installed at the top of the outer wall of the positioning baffle 20. The slider cooperates with an inclined guide rail 21, which is fixedly installed on the side of the outer wall of the frame 1. The inclined guide rail 21 constrains and guides the positioning baffle 20 to move in and out on a horizontal plane. An elastic pressure plate 5 is fixedly installed on the side of the inner wall of the positioning baffle 20.

[0042] Specifically, when the support plate 3 moves upward under the drive of the moving platform mechanism 2, the support plate 3 drives the fixed fulcrum (fulcrum seat) on the side to move upward synchronously;

[0043] The fixed fulcrum drives the middle part (swing fulcrum) of the lever 22 to move upward. Since one end of the lever 22 is connected to the positioning baffle 20 through the traction rod 23, and the positioning baffle 20 is constrained on the inclined guide rail 21 by the slider, the lever 22 swings clockwise around the swing fulcrum.

[0044] The swing of lever 22 pulls positioning baffle 20 upward along inclined guide rail 21 via traction rod 23 (inclined guide rail angle 30°). While sliding upward, positioning baffle 20 moves in the material direction.

[0045] When the vertical surface of the positioning baffle 20 comes into contact with the material, the elastic pressure plate 5 first comes into contact with the material, the positioning baffle 20 continues to move, the elastic pressure plate 5 generates elastic deformation, applies flexible pressure to the material, and fixes the material in the preset positioning position; at this time, the support plate 3 moves to the highest point, and the die-cutting blade 16 moves downward to die-cut.

[0046] Working principle: Under the constraint of the inclined guide rail, the positioning baffle moves quickly to the edge of the material in conjunction with the transmission of the lever and the traction rod. At the same time, the elastic pressure plate on the inner wall of the positioning baffle adheres to the material, realizing the precise positioning and fixation of the material to be die-cut, and preventing the material from shifting during the die-cutting process. The negative pressure adsorption hole adsorbs the die-cutting blade onto the upper surface of the support plate, and the positioning pin and magnetic block further assist in the positioning of the die-cutting blade.

[0047] The servo motor drives the cam to rotate, and the outer contour of the cam pushes the driven roller to move. The driven roller drives the support plate to move up and down along the guide column axis through the rocker arm. The buffer spring on the outer wall of the guide column plays a shock absorption role and avoids direct collision between the support plate and the limit block.

[0048] After die-cutting is completed, the cam continues to rotate, and the driven roller drives the support plate to move upward. The die-cutting blade separates from the die-cut material, and the positioning baffle is reset under the reverse transmission of the lever and the traction rod.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
