Description

Technical Field

[0001] This utility model belongs to the field of die-cutting machine technology, specifically a positioning and adjustment device for a die-cutting machine. Background Technology

[0002] Die cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are important equipment for post-printing packaging processing. They are mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc.

[0003] The working principle of a die-cutting machine is to use physical pressure and the synergy of a die to process continuous rolls or sheets into finished products of specific shapes. Its core lies in achieving precise cutting through three main modules: pressure transmission, die matching, and motion control. Through long-term use and observation, it has been found that misalignment between the material and the die-cutting plate during material cutting can lead to burrs, tears, or dimensional deviations at the cut edges, resulting in products that do not meet specifications.

[0004] Therefore, this utility model provides a positioning and adjustment device for a die-cutting machine. Utility Model Content

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown, a positioning and adjusting device for a die-cutting machine according to an embodiment of the present invention includes a worktable 1; a pair of first upright plates 11 are fixedly mounted on the top of the worktable 1; the pair of first upright plates 11 are symmetrically arranged on both sides of the worktable 1; a first motor 12 is mounted on one side of the first upright plate 11; a take-up roller 13 is fixedly connected to the output end of the first motor 12; the take-up roller 13 rotates between the pair of first upright plates 11; a pair of second upright plates 14 are fixedly mounted on the top of the worktable 1; the pair of second upright plates 14 are symmetrically arranged on both sides of the worktable 1; an unwinding roller 15 is rotatably connected between the pair of second upright plates 14; the unwinding roller 15 and the take-up roller 13 are correspondingly arranged; a pair of third upright plates are fixedly mounted on the top of the worktable 1. Plate 16; a pair of third upright plates 16 are symmetrically arranged on both sides of the workbench 1; a support plate 17 is fixed between the pair of third upright plates 16; a second motor 18 is assembled in the middle of the side wall of one of the third upright plates 16; a threaded rod 19 is fixedly connected to the output end of the second motor 18; the threaded rod 19 rotates inside the support plate 17; a movable ring 110 is slidably connected in the middle of the side wall of the threaded rod 19; a die-cutting plate 111 is assembled in the middle of the side wall of the movable ring 110; a power cord 112 is fixedly connected in the middle of the side wall of the die-cutting plate 111; a shelf 113 is fixed between the pair of third upright plates 16; the shelf 113 is located below the die-cutting plate 111; a smoothing component is provided in the middle of the side wall of the third upright plate 16; A leveling component is located between the platform 113 and the die-cutting plate 111; an adjusting component is located between the second upright plate 14 and the third upright plate 16; a dust-collecting component is located in the middle of the side wall of the third upright plate 16; during operation, the operator attaches a magnetic positioning strip to the back of the paper, plastic, or metal sheet to be die-cut, then winds it onto the unwinding roller 15, and secures the other end of the strip around the leveling component and the platform 113 to the take-up roller 13. Then, the first motor 12 is started, which drives the take-up roller 13 to rotate. As the take-up roller 13 rotates, it winds up the material wrapped around the unwinding roller 15, causing the material to continuously move on the platform 113. Then, the operation continues... The second motor 18 is activated, which drives the threaded rod 19 to rotate. When the threaded rod 19 rotates, it drives the movable ring 110 to slide along its side wall. At this time, the movable ring 110 drives the die-cutting plate 111 to move. Then, the operator connects the power cord 112 and turns on the die-cutting plate 111. At this time, the die-cutting plate 111 will perform die-cutting operations on the material during the movement. During the process of the material being wound from the unwinding roller 15 to the winding roller 13, the adjusting component will attract the magnetic positioning strip on the back of the material to correct and position the material. At the same time, the dust collection component will clean the dust on the surface of the material during the die-cutting process with the assistance of the smoothing component, keeping the material clean.

[0025] like Figures 1 to 3As shown, the adjustment assembly includes a pair of connecting plates 2; the pair of connecting plates 2 are respectively fixed between the second upright plate 14 and the third upright plate 16; multiple regulating valves 21 are rotatably connected to the middle of the side wall of one side connecting plate 2; the multiple regulating valves 21 are staggered; a reciprocating screw 22 is fixedly connected to the end of the regulating valve 21; a pair of electromagnetic rings 23 are slidably connected to the middle of the side wall of the reciprocating screw 22; the pair of electromagnetic rings 23 move towards each other on the reciprocating screw 22; during operation, the operator adjusts the electromagnetic rings 23 according to the position of the magnetic positioning strip on the back of the material to be die-cut, and by rotating the multiple regulating valves 21, the regulating valves 21 drive the reciprocating screw 22 to rotate between the pair of connecting plates 2, so that the pair of electromagnetic rings 23 move along the reciprocating screw. 22. The side wall slides, and after the electromagnetic ring 23 is adjusted to the appropriate position, the position of the electromagnetic ring 23 is fixed. When the material is unwound from the unwinding roller 15, it will automatically correct its deviation due to the mutual attraction between the magnetic positioning strip on its back and the electromagnetic ring 23. This step can automatically adjust the position of the material to be die-cut by setting the connecting plate 2, regulating valve 21, reciprocating screw 22 and electromagnetic ring 23, so that the material is precisely aligned with the die-cutting plate 111, reducing repeated cutting or material scrap caused by position deviation, ensuring that the product meets the design requirements. At the same time, this setting can reduce the offset material from getting stuck in the mechanical structure, causing equipment downtime or damage, reducing downtime adjustment time, reducing equipment failure rate, and realizing continuous high-speed production.

[0026] like Figures 1 to 4 As shown, the leveling assembly includes a third motor 3; the third motor 3 is mounted on the side wall of the third vertical plate 16; a first movable shaft 31 is fixedly connected to the output end of the third motor 3; a synchronous belt 32 is driven and connected to the middle of the side wall of the first movable shaft 31; a second movable shaft 33 is driven and connected to the middle of the inner side wall of the synchronous belt 32; leveling rollers 34 are fixedly connected to the ends of both the second movable shaft 33 and the first movable shaft 31; the leveling rollers 34 rotate between a pair of third vertical plates 16; the leveling rollers 34 are located between the die-cutting plate 111 and the shelf 113; a pair of leveling rollers 34 are respectively located on both sides of the die-cutting plate 111; during operation, the operator starts the third motor 3, which drives the first movable shaft 31 to rotate, and the rotation of the first movable shaft 31 drives the synchronous belt 31 to rotate. 2. When the synchronous belt 32 rotates, it will drive the second movable shaft 33 to rotate. At this time, a pair of smoothing rollers 34 will rotate simultaneously under the drive of the first movable shaft 31 and the second movable shaft 33. When the material to be die-cut passes between the smoothing rollers 34 and the table 113, the smoothing rollers 34 will smooth its surface by rolling. This step sets up the third motor 3, the first movable shaft 31, the synchronous belt 32, the second movable shaft 33 and the smoothing rollers 34. The material can be flattened by physical or mechanical means, so that the die-cutting plate 111 is completely aligned with the material position, reducing the cutting deviation caused by the bending, curling or warping of the material surface, so that the die-cutting plate 111 is evenly stressed, and reducing the inconsistent cutting depth or mold damage caused by local pressure concentration.

[0027] like Figure 1 and Figure 3 As shown, a movable roller 4 is rotatably connected between a pair of connecting plates 2; an adjusting ring 41 is slidably connected to the middle of the side wall of the movable roller 4; when the material to be die-cut continues to move between the platform 113 and the smoothing roller 34 after passing under the adjusting ring 41, the adjusting ring 41 will move along the movable roller 4 under the fine adjustment of the material. At the same time, the material will be tightened due to tension when passing through the adjusting ring 41. This step, by setting the movable roller 4 and the adjusting ring 41, can reduce the uneven cutting edges, size deviations or pattern misalignment caused by wrinkles, waves or looseness due to uneven tension during the conveying process. This setting can maintain the flatness of the material, make the mold and the material strictly aligned, and further improve the cutting accuracy.

[0028] like Figure 3 and Figure 4 As shown, the dust collection assembly includes an air storage box 5; the air storage box 5 is fixed on the side wall of the third upright plate 16; an air extraction pipe 51 is fixed in the middle of the side wall of the air storage box 5; multiple air inlets 52 are opened in the middle of the side wall of the air storage box 5; the air storage box 5, the air extraction pipe 51 and the air inlets 52 are all hollow and connected; during operation, the operator connects the air extraction pipe 51 to the vacuum pump. Because the air storage box 5, the air extraction pipe 51 and the air inlets 52 are connected, the dust on the material surface will enter the interior of the air storage box 5 through the multiple air inlets 52, and the smoothing assembly will press on the material surface to prevent the material from shifting. This step, by setting up the air storage box 5, the air extraction pipe 51 and the air inlets 52, can reduce the interference of dust, particles or fibers attached to the material surface with the contact between the cutting mold and the material, resulting in burrs on the cutting edge, dimensional deviations or pattern misalignment.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, protective baffles 6 are rotatably connected to both sides of the support plate 17; the protective baffles 6 are made of transparent material; this step of setting up protective baffles 6 can form a semi-enclosed dust removal space through physical isolation, which can limit dust to a local area and reduce its diffusion to the material surface or the inside of the equipment.

[0030] like Figure 3 and Figure 4 As shown, multiple elastic pads 7 are fixed in the middle of the side wall of the smoothing roller 34; the elastic pads 7 are made of smooth material; this step can automatically adjust the contact pressure according to the material thickness by setting the elastic pads 7, thereby reducing the cutting deviation or material tearing caused by uneven pressure.

[0031] Working principle: The operator attaches a magnetic positioning strip to the back of the paper, plastic, or metal sheet to be die-cut, then winds it onto the unwinding roller 15, and secures the other end of the strip around the leveling assembly and the platform 113 to the winding roller 13. The first motor 12 is then started, driving the winding roller 13 to rotate. As the winding roller 13 rotates, it winds up the material wrapped around the unwinding roller 15, causing the material to move continuously on the platform 113. Then, the second motor 18 is started, driving the threaded rod 19 to rotate. As the threaded rod 19 rotates, it causes the movable ring 110 to slide along its side wall. At this time, the movable ring 110... The die-cutting plate 111 is moved, and then the operator connects the power cord 112 and turns on the die-cutting plate 111. At this time, the die-cutting plate 111 will perform die-cutting operations on the material during the movement. During the process of the material being wound from the unwinding roller 15 to the winding roller 13, the adjusting component will attract the magnetic positioning strip on the back of the material to correct the material's deviation and position it. At the same time, the dust collection component will clean the dust on the surface of the material during the die-cutting process with the assistance of the leveling component, keeping the material clean. The operator adjusts the electromagnetic ring 23 according to the position of the magnetic positioning strip on the back of the material to be die-cut, and by rotating multiple adjusting valves 21, the adjusting valves 21 drive the reciprocating screw 22 to... The rotation between the pair of connecting plates 2 causes a pair of electromagnetic rings 23 to slide along the side wall of the reciprocating screw 22. After the electromagnetic rings 23 are adjusted to the appropriate position, their position is fixed. When the material is unwound from the unwinding roller 15, it will automatically correct its deviation due to the mutual attraction between the magnetic positioning strip on its back and the electromagnetic rings 23. The operator starts the third motor 3, which drives the first movable shaft 31 to rotate. When the first movable shaft 31 rotates, it drives the synchronous belt 32 to rotate. When the synchronous belt 32 rotates, it drives the second movable shaft 33 to rotate. At this time, a pair of leveling rollers 34 will rotate simultaneously under the drive of the first movable shaft 31 and the second movable shaft 33. When the die-cutting material passes between the smoothing roller 34 and the table 113, the smoothing roller 34 will smooth its surface by rolling. When the die-cutting material passes under the adjusting ring 41 and continues to move between the table 113 and the smoothing roller 34, the adjusting ring 41 will move along the movable roller 4 under the fine adjustment of the material. At the same time, the material will be tightened due to tension when it passes the adjusting ring 41. The operator connects the air extraction pipe 51 to the vacuum pump. Because the air storage box 5, the air extraction pipe 51 and the air inlet 52 are connected, the dust on the surface of the material will enter the air storage box 5 from multiple air inlets 52. The smoothing component will press on the surface of the material to prevent the material from shifting.
