Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a precise positioning structure of an anti-offset die-cutting machine. Background Technique

[0002] A die-cutting machine is also called a beer machine, a cutting machine, a numerical control stamping machine. The die-cutting machine uses a steel knife, a hardware mold, a steel wire (or a template engraved from a steel plate), and applies a certain pressure through an impression plate to roll and cut printed matter or cardboard into a certain shape. It is an important device for post-printing packaging processing and forming;

[0003] For example, the patent number CN218659425U discloses a positioning structure and a die-cutting machine, including a base, and a workbench is fixedly connected to the middle part above the base; a rotating frame is arranged above the front and rear sides of the base and is rotatably connected to the base; the beneficial effects are: through the structure of the rotating frame, it prevents the clamping plate from hindering the installation of the material on the workbench. Through the structure of the clamping plate and the spring, the clamping plate clamps and positions the material on the workbench. Through the abutting of the abutting rod and the abutting groove, and the damping rotation of the rotating block and the outer side of the clamping plate, after the clamping plate fixes the material, the relative distance between the clamping plate and the rotating frame is positioned, preventing the clamping plate from still sliding on the rotating frame and causing loosening of the clamping. Through the insertion structure of the positioning rod and the insertion slot, it prevents the rotating frame from flipping outwards and causing the problem of unstable material positioning; the die-cutting machine positioning structure in this patent only relies on the clamping plate to fix the material, lacking the anti-offset function for the material. The material may be offset due to mistakes in the feeding process, resulting in affecting the positioning accuracy of the die-cutting machine.

[0004] Therefore, aiming at the problem that the die-cutting machine positioning structure lacks the anti-offset function for the material, resulting in affecting the positioning accuracy of the die-cutting machine, a precise positioning structure of an anti-offset die-cutting machine can be designed. By setting an adjustable centering anti-offset structure, the anti-offset centering of materials with different sizes can be realized, and then a clamping structure is used for clamping to improve the positioning accuracy of the die-cutting machine. Content of the Utility Model

[0005] In order to overcome the problem that the die-cutting machine positioning structure lacks the anti-offset function for the material, resulting in affecting the positioning accuracy of the die-cutting machine.

[0006] The technical solution of the utility model is: a precise positioning structure for an anti-offset die-cutting machine, which includes a workbench. A moving plate is arranged outside the workbench. A bidirectional motor is fixedly installed on the front side of the lower end of the workbench. Lead screws are arranged on the left and right sides of the bidirectional motor. Support plates are fixedly installed on the left and right sides of the lower end of the workbench. A first slide rod is arranged at the rear side below the workbench. Guide columns and a lifting plate are arranged on the upper end of the moving plate. Clamping plates are arranged on the side edges of the lower end of the lifting plate. Support bars are fixedly installed on the front and rear sides of the lifting plate. An electric push rod is fixedly installed on the lower end of the workbench. A lifting frame is fixedly installed on the lower end of the electric push rod. Second slide rods are arranged at the front and rear ends of the lifting frame.

[0007] Preferably, two moving plates are arranged symmetrically left and right. Through slots are arranged through the left and right of the surface of the moving plate, and the workbench is slidably connected to the inside of the through slots.

[0008] As a preference, two lead screws and two support plates are both arranged symmetrically left and right. One end of the lead screw is fixedly connected to the output end of the bidirectional motor, and the other end of the lead screw is rotatably connected to the surface of the support plate. Installation holes are opened on the side edges of the lower end of the support plate.

[0009] As a preference, the left and right ends of the first slide rod are fixedly connected to the support plate. The lower end of the moving plate is threadedly connected to the outside of the lead screw and is slidably connected to the outside of the first slide rod.

[0010] As a preference, the lower end of the guide column is fixedly connected to the moving plate. A limit plate is fixedly installed at the upper end of the guide column. The lifting plate is designed in a U-shaped structure and is slidably connected to the guide column through a through hole.

[0011] As a preference, two lifting plates are arranged symmetrically left and right and are slidably sleeved on the upper end of the moving plate. The clamping plates are located on one side where the two lifting plates are close to each other and are fixedly connected to the lifting plates. Anti-slip gaskets are fixedly installed at the lower ends of the clamping plates.

[0012] As a preference, two second slide rods are arranged symmetrically front and rear. The left and right ends of the second slide rod are fixedly connected to the lifting frame. The lower end of the support bar is slidably connected to the surface of the second slide rod through a through hole.

[0013] The beneficial effects of the utility model:

[0014] For this precise positioning structure of the anti-offset die-cutting machine, the bidirectional motor drives the two lead screws to rotate, making the two moving plates approach each other, realizing the rapid centering and limiting of the material, effectively preventing the material from shifting. By controlling the electric push rod to work and driving the lifting frame to descend, the second slide rod pulls the support bar to descend, so that the two lifting plates drive the clamping plates to descend until the anti-slip gasket is in close contact with the side of the material, clamping and fixing the material, and realizing the precise positioning of the die-cutting machine for the material.

[0023] Please refer to Figures 1 - 4, in this embodiment, there are two moving plates 2 arranged symmetrically left and right. A through groove 21 is arranged through the left and right sides of the surface of the moving plate 2. The inner side of the workbench 1 is slidably connected to the through groove 21. There are two lead screws 4 and two support plates 5 arranged symmetrically left and right. One end of the lead screw 4 is fixedly connected to the output end of the bidirectional motor 3, and the other end of the lead screw 4 is rotatably connected to the surface of the support plate 5. An installation hole is opened at the side of the lower end of the support plate 5. The left and right ends of the first slide rod 6 are fixedly connected to the support plate 5. The lower end of the moving plate 2 is threadedly connected to the outer side of the lead screw 4 and is slidably connected to the outer side of the first slide rod 6. The workbench 1 is installed on the working base of the die cutting machine through the support plate 5. After the feeding mechanism conveys the material to the surface of the workbench 1, the bidirectional motor 3 works to drive the two lead screws 4 to rotate, so that the two moving plates 2 slide on the surface of the workbench 1 and approach each other, realizing the quick centering and limiting of the material and effectively preventing the material from shifting.

[0024] Please refer to Figures 2 - 5 , in this embodiment, the lower end of the guide post 7 is fixedly connected to the moving plate 2, and a limit plate 71 is fixedly installed at the upper end of the guide post 7. The lifting plate 8 is designed in a U-shaped structure and is slidably connected to the guide post 7 through a through hole. There are two lifting plates 8 arranged symmetrically left and right and are slidably sleeved on the upper end of the moving plate 2.

During the movement of the moving plate 2, the lifting plate 8 is driven to move at the same time. The lower end of the support bar 10 slides on the surface of the second slide rod 13. After the material is centered and limited, the electric push rod 11 is controlled to work to drive the lifting frame 12 to descend, so that the second slide rod 13 pulls the support bar 10 to descend, so that the two lifting plates 8 slide along the guide post 7 to drive the clamping plate 9 to descend until the anti-slip gasket is in close contact with the side of the material, clamping and fixing the material, and realizing the precise positioning of the die cutting machine for the material.

[0026] Through the above steps, the bidirectional motor 3 is used to drive the two lead screws 4 to rotate, so that the two moving plates 2 approach each other, realizing the rapid centering and limiting of the material. By controlling the operation of the electric push rod 11 to drive the lifting frame 12 to descend, the second sliding rod 13 pulls the support bar 10 to descend, so that the two lifting plates 8 drive the clamping plate 9 to descend until the anti-slip gasket is in close contact with the side of the material, clamping and fixing the material, so as to solve the problem that the positioning structure of the die-cutting machine lacks the anti-offset function for the material, resulting in affecting the positioning accuracy of the die-cutting machine.
