Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a precision positioning mechanism for a high-precision positioning die-cutting machine. Background Technology

[0002] Die-cutting is one of the most commonly used processes in packaging and printing. It involves using die-cutting blades to assemble a die-cutting plate according to the product design requirements, and then cutting the printed material or other coiled blanks into the required shape or with creases under pressure. Usually, die-cutting and creasing processes combine the die-cutting blade and the creasing blade in the same template, and perform die-cutting and creasing simultaneously on the die-cutting machine. It plays an important role in modern manufacturing fields such as electronics, packaging, and printing.

[0003] Traditional positioning mechanisms in die-cutting machines typically require additional mechanisms to secure the workpiece after positioning, increasing the complexity of the equipment structure and operational procedures. These additional fixing mechanisms also increase the number of mechanical parts, raising manufacturing costs and maintenance difficulties, extending pre-production preparation time, and reducing production efficiency. In contrast, this invention provides a high-precision positioning mechanism for a die-cutting machine that automatically locks the workpiece after positioning, eliminating the need for additional fixing mechanisms. This significantly simplifies the equipment structure and operational procedures, thereby improving production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a precise positioning mechanism for a high-precision die-cutting machine, aiming to improve the problem that existing die-cutting machine positioning mechanisms require other mechanisms to fix the workpiece after positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision positioning mechanism for a high-precision die-cutting machine, comprising a base, a slide rail fixedly connected inside the base, a slide plate slidably connected to the outer wall of the slide rail, a rotating rod rotatably connected inside the base, transmission rods rotatably connected to both sides of the rotating rod, one side of the transmission rod rotatably connected to the top of the slide plate, a cylinder fixedly connected inside the base, the output end of the cylinder fixedly connected to one side of the outer wall of the slide plate, a connecting rod rotatably connected inside the slide plate, a gripper rotatably connected to the top of the base, one side of the connecting rod rotatably connected to one side of the gripper, a rack fixedly connected to the top of the slide plate, a gear rotatably connected inside the base, the slide plate meshing with the outer wall of the gear, a sliding block slidably connected inside the base, a rack fixedly connected to the bottom of the sliding block, the rack meshing with the outer wall of the gear, a rotation limiting block rotatably connected to the top of the sliding block, a roller rotatably connected inside the rotation limiting block, and a placement assembly provided on the top of the base for placing the workpiece to be processed.

[0006] Furthermore, the placement assembly includes a processing table, the bottom of which is fixedly mounted on the top of the base.

[0007] Furthermore, multiple fixing brackets are fixedly connected to the outer wall of the base, and mounting columns are fixedly connected inside the fixing brackets.

[0008] Furthermore, the mounting post has a threaded post internally connected to it, and a drive block is fixedly connected to one end of the threaded post.

[0009] Furthermore, a movable block is rotatably connected to the bottom of the threaded column, and a limit rod is fixedly connected inside the mounting column.

[0010] Furthermore, the outer wall of the limiting rod is slidably connected inside the moving block, and a sliding rod is fixedly connected inside the mounting column.

[0011] Furthermore, the movable block is rotatably connected to a ring array of push-pull rods, and the outer wall of the slide rod is slidably connected to a slider.

[0012] Furthermore, one side of the push-pull rod is rotatably connected inside the slider, and a locking block is fixedly connected to one side of the outer wall of the slider.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the slide plate on one side is first driven by a cylinder. Then, the rotating rod and the transmission rod work together to make the slide plates on both sides move synchronously. The slide plate can drive the gear to rotate through the rack one, thereby driving the rotating limit block to move and position towards the center of the processing table with the help of the rack two and the sliding block. At the same time, the slide plate can push the gripper to press the object through the connecting rod. This solves the problem of fixing the object to be processed through other mechanisms after positioning. It realizes the integrated design of positioning and fixing, and improves the efficiency of the die-cutting machine.

[0015] 2. In this utility model, the threaded column can be driven to rotate by the drive block, thereby pushing the moving block. The moving block pushes the slider to slide on the slide rod through the push-pull rod, which can control the card block to be inserted into the preset card slot of the die-cutting machine. This solves the problem of the mechanism being inconvenient to disassemble and install, and improves the convenience of replacing the mechanism. Attached Figure Description

[0021] 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.

[0022] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a high-precision die-cutting machine's precise positioning mechanism, comprising a base 1, a slide rail 12 fixedly connected inside the base 1, a slide plate 11 slidably connected to the outer wall of the slide rail 12, a rotating rod 9 rotatably connected inside the base 1, transmission rods 10 rotatably connected to both sides of the rotating rod 9, one side of the transmission rod 10 rotatably connected to the top of the slide plate 11, a cylinder 8 fixedly connected inside the base 1, the output end of the cylinder 8 fixedly connected to one side of the outer wall of the slide plate 11, a connecting rod 13 rotatably connected inside the slide plate 11, a gripper 3 rotatably connected to the top of the base 1, and one side of the connecting rod 13 rotatably connected to... A rack 14 is fixedly connected to the top of the slide plate 11 on one side of the gripper 3. A gear 15 is rotatably connected inside the base 1. The slide plate 11 meshes with the outer wall of the gear 15. A sliding block 17 is slidably connected inside the base 1. A rack 16 is fixedly connected to the bottom of the sliding block 17. The rack 16 meshes with the outer wall of the gear 15. A rotation limit block 4 is rotatably connected to the top of the sliding block 17. A roller 5 is rotatably connected inside the rotation limit block 4. A placement component is provided on the top of the base 1. The placement component is used to place the workpiece to be processed. The placement component includes a processing table 2. The bottom of the processing table 2 is fixedly installed on the top of the base 1.

[0023] Specifically, when materials need to be processed, they are first placed on the processing table 2 on top of the base 1. The surface of the processing table 2 has been finely ground. After the materials are placed, the piston rod of the cylinder 8 extends, pushing the slide plate 11 on one side to slide on the slide rail 12. The slide rail 12 consists of two parallel linear guide rails, which greatly reduces the friction and wobbling of the slide plate 11 when it slides, ensuring that the slide plate 11 can slide smoothly along a straight track. The slide plate 11 on this side is connected to the transmission rod 10 through a hinge. When the slide plate 11 slides on the slide rail 12, it will be driven by the transmission rod on this side. Rod 10 pulls rotating rod 9 to rotate. The rotation of rotating rod 9 drives the other side slide plate 11 to slide synchronously through the other side transmission rod 10. This linkage structure design ensures the consistency and coordination of the movement of the two slide plates 11. A rack 14 is fixedly installed on the top of the slide plate 11. As the slide plate 11 slides, rack 14 moves accordingly, thus meshing with gear 15 and driving gear 15 to rotate. Gear 15 then drives sliding block 17 to slide through meshing with rack 16. A rotation limit block 4 is installed on the top of sliding block 17. The rotation limit block 4 adopts an L-shape. The structure features a wear-resistant polyurethane layer inlaid on its inner surface, effectively protecting the material surface from scratches. A roller 5 is mounted on the rotating limit block 4, using a deep groove ball bearing as the rotating component. The roller 5 is coated with a layer of nitrile rubber, ensuring good clamping force on the material while reducing friction during material movement. As the sliding block 17 slides, the rotating limit block 4 moves towards the center, working with the roller 5 to center the material. During positioning, the roller 5 automatically adjusts its angle according to the shape and position of the material, ensuring the material can be... The slide plate 11 is accurately positioned at the center of the processing table 2. At the same time, during the movement of the slide plate 11, it pushes the connecting rod 13. One end of the connecting rod 13 is hinged to the slide plate 11, and the other end is hinged to the gripper 3. When the connecting rod 13 is pushed, it will push the gripper 3 to rotate around the hinge point. The inner surface of the gripper 3 is designed with anti-slip teeth, which can effectively increase the friction with the surface of the object. As the gripper 3 rotates, it will press against the surface of the object placed on the processing table 2, thereby fixing the object for processing and preventing loosening and displacement during the processing.

[0024] Reference Figure 1 and Figure 3The base 1 has multiple fixed brackets 6 fixedly connected to its outer wall. The fixed brackets 6 have mounting columns 7 fixedly connected inside. The mounting columns 7 have threaded columns 19 threadedly connected inside. One end of the threaded column 19 is fixedly connected to a drive block 18. The bottom of the threaded column 19 is rotatably connected to a moving block 21. The mounting column 7 has a limit rod 20 fixedly connected inside. The outer wall of the limit rod 20 is slidably connected to the inside of the moving block 21. The mounting column 7 has a slide rod 23 fixedly connected inside. The moving block 21 has a ring array of push-pull rods 22 rotatably connected inside. The outer wall of the slide rod 23 is slidably connected to a slider 24. One side of the push-pull rod 22 is rotatably connected to the inside of the slider 24. One side of the outer wall of the slider 24 is fixedly connected to a locking block 25.

[0025] Specifically, when installing and using this mechanism, the base 1 must first be placed on the designated mounting surface of the die-cutting machine, ensuring that the base 1 is completely flush with the surface of the die-cutting machine to avoid tilting or shaking. The drive block 18 in this mechanism has a hexagonal surface, compatible with a standard hex wrench. Rotating the drive block 18 with the wrench transmits the rotation of the drive block 18 to the threaded column 19, causing the threaded column 19 to rotate synchronously. The threaded column 19 and the nut seat inside the mechanism form a helical transmission pair. According to the principle of helical transmission, when the threaded column 19 rotates, it will generate displacement in the axial direction. As the threaded column 19 rotates and advances, it will generate thrust on the moving block 21. The moving block 21 is provided with limit holes, which cooperate with two parallel limit rods 20. The limit rods 20 not only provide precise guidance for the moving block 21 but also effectively limit the rotation or offset of the moving block 21 during movement, ensuring that the moving block 21 can only move along the limit rods 20. The sliding block 21 slides downward along the axial direction of the 0. The bottom of the moving block 21 is connected to the push-pull rod 22 by a hinge. When the moving block 21 slides downward along the limit rod 20, the displacement of its hinge point will cause the push-pull rod 22 to swing. The other end of the push-pull rod 22 is hinged to the slider 24. The slider 24 is fitted on the slide rod 23. The surface of the slide rod 23 is treated with high precision grinding. With the use of lubricating oil, the friction of the slider 24 during sliding can be greatly reduced, so that the slider 24 can slide outward along the slide rod 23. A locking block 25 is vertically fixed on the outer wall of the slider 24. The size and shape of the locking block 25 match the preset slot of the die-cutting machine. As the slider 24 slides outward, the locking block 25 will be inserted into the slot of the die-cutting machine to form a mechanical locking structure. When the locking block 25 is fully embedded in the slot, the entire mechanism is stably fixed to the die-cutting machine and can withstand various forces generated during the die-cutting operation, ensuring the stability and reliability of the mechanism during operation.

[0026] Working principle: When using this mechanism, the base 1 can be placed on the die-cutting machine. The drive block 18 is then rotated using a wrench, causing the threaded column 19 to rotate. This rotation of the threaded column 19 moves the moving block 21, causing it to slide downwards along the limit rod 20. The downward movement of the moving block 21 pushes the push-pull rod 22, which in turn pushes the slider 24 to slide outwards along the slide rod 23. This controls the locking block 25 on the outer wall of the slider 24 to insert into the pre-set slot of the die-cutting machine, thus fixing the mechanism in place. When the material is placed on the processing table 2 at the top of the base 1, the cylinder 8 can push the sliding plate 11 on one side to slide on the slide rail 12. The 11 will pull the rotating rod 9 to rotate through the transmission rod 10 on this side, so that the rotating rod 9 will drive the sliding plate 11 on the other side to slide synchronously through the transmission rod 10 on the other side. The rack 14 on the top of the sliding plate 11 will move accordingly, thereby driving the gear 15 to rotate. The gear 15 will drive the sliding block 17 to slide through the rack 16, thereby driving the rotation limit block 4 on the top of the sliding block 17 to move towards the center, and cooperating with the roller 5 on the rotation limit block 4 to center the material. While the sliding plate 11 is moving, it will push the connecting rod 13, which will push the gripper 3 to rotate. The gripper 3 will then press against the surface of the object placed on the processing table 2, thereby fixing the object for processing.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
