The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4This application provides a precision positioning device for a fully automatic printing die-cutting machine, including a die-cutting machine body 1. A positioning component 2 is fixedly installed at the bottom of the die-cutting machine body 1. The positioning component 2 includes a fixing frame 21 and a bidirectional threaded rod 22. The fixing frame 21 is fixedly installed at the bottom of the die-cutting machine body 1. The bidirectional threaded rod 22 is connected to the inner side wall of the fixing frame 21 via a bearing. A movable frame 23 is threadedly connected to the side wall of the bidirectional threaded rod 22. A positioning plate 24 is fixedly installed on one side of the movable frame 23. Stabilizing rods 25 are fixedly installed on both sides of the die-cutting machine body 1. The moving frame 23 and the stabilizing rod 25 are slidably connected. A gear 26 is fixedly connected to the side wall of the bidirectional threaded rod 22. The positioning component 2 also includes a motor 27, which is fixedly installed at the bottom of the film cutting machine body 1. A gear 28 is fixedly connected to the output end of the motor 27. The gear 28 and the gear 26 are meshed together. The positioning component 2 also includes a limiting block 29, which is fixedly connected to one end of the stabilizing rod 25. An anti-wear pad is provided on one side of the positioning plate 24. The number of anti-wear pads is equal to that of the positioning plate 24. A cleaning component 3 is fixedly installed on the top of the film cutting machine body 1.

[0033] In this embodiment, when the device is started, the motor 27 drives the gear 28 to rotate, which in turn drives the gear 26 to rotate synchronously through gear meshing. This causes the bidirectional threaded rod 22 to rotate on the inner wall of the fixed frame 21. Due to the thread structure characteristics of the bidirectional threaded rod 22, the two moving frames 23 on it will move in opposite directions or in a straight line along the stabilizing rod 25. The stabilizing rod 25 plays a guiding and stabilizing role, and the limiting block 29 prevents the moving frames 23 from going out of their stroke. When it is necessary to position the printing material, the motor 27 drives the moving frames 23 to move towards each other, causing the positioning plates 24 to move synchronously closer to the edge of the material until the two positioning plates 24 gently contact and clamp the edge of the material through the anti-wear pads, achieving precise positioning. After positioning is completed, the motor 27 remains locked to ensure positioning accuracy.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the cleaning assembly 3 includes a second fixing frame 31 and a slide rod 32. The second fixing frame 31 is fixedly installed on the top of the film cutting machine body 1. The slide rod 32 is slidably connected to the top of the second fixing frame 31. A lifting frame 33 is fixedly connected to the bottom end of the slide rod 32. A cleaning roller 34 is connected to the inner side wall of the lifting frame 33 through a bearing. A spring 35 is sleeved on the side wall of the slide rod 32. A connecting frame 36 is fixedly connected to the top end of the slide rod 32. A wheel 37 is connected to the inner side wall of the connecting frame 36 through a bearing. The cleaning assembly 3 also includes a hydraulic cylinder 38 and a connecting plate 39. The hydraulic cylinder 38 is fixedly installed on the top of the second fixing frame 31. The connecting plate 39 is fixedly connected to the output end of the hydraulic cylinder 38. A trapezoidal block 310 is fixedly installed at the bottom of the connecting plate 39. The cleaning assembly 3 also includes a sliding groove 311. The sliding groove 311 is opened on both sides of the second fixing frame 31. The lifting frame 33 is slidably connected to the sliding groove 311.

[0035] In this embodiment, when the die-cutting area needs to be cleaned, the hydraulic cylinder 38 drives the connecting plate 39 to move forward, causing the trapezoidal block 310 to follow. The wheel 37 rolls on the inclined surface of the trapezoidal block 310 and is compressed. Through the connecting frame 36, the sliding rod 32 slides downward along the fixed frame 31, and the spring 35 is compressed, causing the lifting frame 33 to descend along the slide groove 311, driving the cleaning roller 34 to contact the die-cutting table surface. As the connecting plate 39 continues to move forward, the entire cleaning assembly 3 moves along the table surface. The cleaning roller 34 rotates under the action of friction, rolling and cleaning the table surface to remove paper scraps and impurities. After cleaning is completed, the hydraulic cylinder 38 reverses its action, the trapezoidal block 310 retracts, and the spring 35 resets, causing the cleaning roller 34 to rise and detach from the table surface, returning to its initial position.

[0036] Working principle: When the equipment is started, the motor 27 drives the gear 28 to rotate, which in turn drives the gear 26 to rotate synchronously through gear meshing. This causes the bidirectional threaded rod 22 to rotate on the inner wall of the fixed frame 21. Due to the thread structure characteristics of the bidirectional threaded rod 22, the two moving frames 23 on it will move in opposite directions or in a straight line along the stabilizing rod 25. The stabilizing rod 25 plays a guiding and stabilizing role, and the limiting block 29 prevents the moving frames 23 from going out of their stroke. When it is necessary to position the printing material, the motor 27 drives the moving frames 23 to move towards each other, causing the positioning plates 24 to move synchronously closer to the edge of the material until the two positioning plates 24 gently contact and clamp the edge of the material through the anti-wear pads, achieving precise positioning. After positioning is completed, the motor 27 remains locked to ensure positioning accuracy.

[0037] When the die-cutting area needs cleaning, the hydraulic cylinder 38 drives the connecting plate 39 to move forward, causing the trapezoidal block 310 to follow. The wheel 37 rolls and is pressed on the inclined surface of the trapezoidal block 310, pushing the slide bar 32 downward along the fixed frame 31 via the connecting frame 36. The spring 35 is compressed, causing the lifting frame 33 to descend along the slide groove 311, driving the cleaning roller 34 to contact the die-cutting table surface. As the connecting plate 39 continues to move forward, the entire cleaning assembly 3 moves along the table surface. The cleaning roller 34 rotates under the action of friction, rolling and cleaning the table surface to remove paper scraps and impurities. After cleaning is completed, the hydraulic cylinder 38 reverses its action, the trapezoidal block 310 retracts, and the spring 35 resets, causing the cleaning roller 34 to rise and detach from the table surface, returning to its initial position.
