Description

Technical Field

[0001] This utility model relates to the field of circular die-cutting machine technology, and specifically to a circular die-cutting machine. Background Technology

[0002] Chinese Patent Publication No. CN222874741U discloses a circular die-cutting machine for preventing material deviation during die-cutting. The machine includes a worktable with two fixed plates above it and an anti-deviation assembly between the two fixed plates. The anti-deviation assembly includes two connecting rods, each fixedly connected to a corresponding fixed plate. Each connecting rod has a limit box fixedly connected to one end facing the other, and each limit box has a limit groove on its inner side.

[0003] In the above technical solution, a circular die-cutting machine that prevents material deviation during die-cutting can limit the material and prevent deviation, thus achieving the effect of correction. However, it can only be used for left and right limit of materials of one width, which is not very flexible. Furthermore, the upper and lower clamping limit is based on springs as the clamping power source, which has a certain degree of instability. The material may still jump up and down, resulting in a poor correction effect.

[0004] Therefore, a circular die-cutting machine was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a circular die-cutting machine in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A rotary die-cutting machine includes a fixed plate, a rotary die-cutting assembly on the top of the fixed plate, a gantry frame on the top of the fixed plate, a fixed shell on the surface of the gantry frame, and limiting mechanisms for limiting the material to the left and right sides to prevent deviation on the gantry frame and the fixed shell. The limiting mechanisms are equipped with two sets of clamping mechanisms for clamping the material to the upper and lower sides to prevent jumping.

[0007] Furthermore, the limiting mechanism includes a limiting shaft, which is rotatably mounted on the gantry frame. A gear is fixedly mounted at the bottom end of the limiting shaft. Two moving rods are slidably mounted on the inner wall of the fixed shell. A toothed rod is fixedly mounted on the surface of each of the two moving rods, and the two toothed rods mesh with the gear. A U-shaped plate is fixedly mounted on the surface of each of the two moving rods.

[0008] Furthermore, a worm gear is fixedly installed at the top of the limiting shaft, a connecting shell is fixedly installed at the top of the gantry frame, a T-shaped shaft is rotatably installed inside the connecting shell, a worm is fixedly installed on the outer wall of the T-shaped shaft, and the worm gear meshes with the worm. One end of the T-shaped shaft extends outside the connecting shell, and a knob is fixedly installed at the extended end of the T-shaped shaft.

[0009] Furthermore, the clamping mechanism includes a mounting shell, which is fixedly mounted on the top of the C-shaped plate. A screw is rotatably mounted inside the mounting shell, and a lifting column is threaded onto the outer wall of the screw. The lifting column is slidably mounted on the inner wall of the mounting shell and on the C-shaped plate. The top end of the screw extends outside the mounting shell, and a knob is fixedly mounted on one end of the extended end of the screw.

[0010] Furthermore, a lifting plate is fixedly installed at the bottom end of the lifting column, and the lifting plate is located inside the U-shaped plate.

[0011] Furthermore, a lower fixing frame is fixedly installed on the surface of the C-shaped plate, and multiple lower rollers are rotatably installed on the lower fixing frame; an upper fixing frame is fixedly installed on the surface of the lifting plate, and an upper roller is rotatably installed on the upper fixing frame.

[0012] The beneficial effects of this utility model are as follows: This utility model, through the setting of limiting mechanisms and clamping mechanisms, etc., during use, according to the width of the material, the limiting mechanism contacts the left and right sides of the material to limit it, locking the material from the left and right directions, which can eliminate the material's drift, swing or snake-like movement in any lateral direction. Then, two sets of clamping mechanisms clamp the upper and lower sides of the material to further limit it, clamping the material from the upper and lower directions, which can eliminate the material's vertical jumping, vibration and instability in the thickness direction. This fundamentally ensures the ultimate precision of the single die-cut size during the die-cutting process, avoiding problems such as cutting deviation, incomplete cutting or cutting the substrate caused by material vibration. Thus, it can achieve positioning and correction of materials with various width and thickness specifications, with high flexibility, good correction effect, improved die-cutting accuracy, simple operation and strong practicality.

[0020] like Figure 1-2As shown, a circular die-cutting machine includes a fixed plate 1, with a circular die-cutting assembly 2 mounted on the top of the fixed plate 1. The machine is characterized by a gantry frame 3 mounted on the top of the fixed plate 1, a fixed shell 4 mounted on the surface of the gantry frame 3, and limiting mechanisms 5 for preventing material deviation on the left and right sides of the gantry frame 3 and the fixed shell 4. Figure 1-3 As shown, specifically, the limiting mechanism 5 includes a limiting shaft 501, which is rotatably mounted on the gantry frame 3. A gear 502 is fixedly mounted at the bottom end of the limiting shaft 501. Two moving rods 503 are slidably mounted on the inner wall of the fixed housing 4. A toothed rod 504 is fixedly mounted on the surface of each of the two moving rods 503, and the two toothed rods 504 mesh with the gear 502. A U-shaped plate 505 is fixedly mounted on the surface of each of the two moving rods 503. A worm gear 506 is fixedly mounted at the top end of the limiting shaft 501. A connecting housing 507 is fixedly mounted at the top of the gantry frame 3. A T-shaped shaft 508 is rotatably mounted inside the connecting housing 507. A worm gear 509 is fixedly mounted on the outer wall of the T-shaped shaft 508, and the worm gear 506 meshes with the worm gear 509. One end of the T-shaped shaft 508 extends outside the connecting housing 507, and a knob 510 is fixedly mounted on the extended end of the T-shaped shaft 508.

[0021] More specifically, by rotating knob 510, the T-shaped shaft 508 is driven to rotate, and the worm gear 509 rotates accordingly, driving the worm wheel 506 to rotate, causing the limiting shaft 501 and gear 502 to rotate as well. The gear 502 drives the two racks 504, causing the two moving rods 503 to move closer to or further away from each other, and the two C-shaped plates 505 move accordingly, thereby realizing the adjustment of the distance between the two C-shaped plates 505, making it suitable for left and right limiting of materials of various width specifications.

[0022] The limiting mechanism 5 is equipped with two sets of clamping mechanisms 6 for clamping the material on both the upper and lower sides to prevent it from jumping; for example Figure 1-3 As shown, specifically, the clamping mechanism 6 includes a mounting shell 603, which is fixedly mounted on the top of the C-shaped plate 505. A screw 604 is rotatably mounted inside the mounting shell 603. A lifting column 605 is threadedly mounted on the outer wall of the screw 604, and the lifting column 605 is slidably mounted on the inner wall of the mounting shell 603. The lifting column 605 is slidably mounted on the C-shaped plate 505. The top end of the screw 604 extends outside the mounting shell 603, and a knob 607 is fixedly mounted on one end of the extended end of the screw 604. A lifting plate 606 is fixedly mounted on the bottom end of the lifting column 605, and the lifting plate 606 is located inside the C-shaped plate 505. A lower fixing frame 601 is fixedly mounted on the surface of the C-shaped plate 505, and multiple lower rollers 602 are rotatably mounted on the lower fixing frame 601. An upper fixing frame 608 is fixedly mounted on the surface of the lifting plate 606, and an upper roller 609 is rotatably mounted on the upper fixing frame 608.

[0023] More specifically, after the position between the two C-shaped plates 505 is adjusted, by placing the material on the lower roller 602, the knob 607 can be turned to drive the screw 604 to rotate, causing the lifting column 605 to move downwards. The lifting plate 606, the upper fixed frame 608, and the multiple upper rollers 609 move accordingly. The multiple upper rollers 609 clamp the material onto the multiple lower rollers 602, thus clamping it. When the material is conveyed, it will drive the multiple lower rollers 602 and the multiple upper rollers 609 to rotate, thereby achieving upper and lower limit positioning to accommodate materials of various thicknesses.

[0024] In summary, the circular die-cutting assembly 2 comprises a circular die, bearing housing, drive gear, bottom roller, and servo motor, which are existing technologies and common knowledge, and therefore require no further explanation. During use, the limiting mechanism 5 contacts the left and right sides of the material according to its width, limiting and locking the material from the left and right directions. This eliminates any lateral drift, swaying, or serpentine movement of the material. Then, two sets of clamping mechanisms 6 clamp the material from the top and bottom, further limiting it and eliminating vertical jumping, vibration, and instability in the thickness direction. This fundamentally ensures the extreme precision of the single die-cut dimension during the die-cutting process, avoiding problems such as off-center cutting, incomplete cutting, or damage to the substrate caused by material vibration. This allows for positioning and correction of materials with various widths and thicknesses, offering high flexibility, excellent correction effect, improved die-cutting accuracy, simple operation, and strong practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
