Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and more specifically, to a die-cutting machine equipped with a leveling mechanism. 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. For example, the die-cutting machine proposed in application number "CN202010351458.7" includes a mounting box with a through-hole central cavity. The central cavity contains a push-die-cutting device that uses a direct push method and spring rebound to achieve die-cutting. Symmetrical vertical plates are fixed on both sides of the mounting box. One side of each vertical plate is equipped with a transmission clamping device for clamping the die-cutting raw material to achieve simultaneous clamping and transmission. The central cavity contains the raw material, which is introduced from the external space into the transmission clamping device and then clamped and conveyed.

[0003] However, in the above technical solutions, the raw materials are prone to unevenness during the conveying process due to their own wrinkles, folds, or uneven conveying tension. This affects the fit between the cutting tool and the raw material during the die-cutting process, which not only reduces the die-cutting accuracy and causes problems such as die-cutting size deviation and irregular edges, but may also cause uneven force on the cutting tool due to local protrusions or depressions in the raw material, affecting the service life of the cutting tool. Therefore, we propose a die-cutting machine with a leveling mechanism to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a die-cutting machine with a leveling mechanism, which solves the problem that unevenness caused by the raw material during the conveying process due to its own wrinkles, folds, or uneven conveying tension will affect the fit between the cutter and the raw material during the die-cutting process. This will not only reduce the die-cutting accuracy and cause problems such as die-cutting size deviation and irregular edges, but may also cause uneven force on the cutter due to local protrusions or depressions in the raw material, thus affecting the service life of the cutter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A die-cutting machine with a leveling mechanism includes a worktable. A leveling mechanism is mounted on one end of the upper surface of the worktable.

A base plate is mounted within the lower end of the second support. A cutting tool is mounted on the lower surface of the base plate, and the cutting tool and the raw material overlap vertically. A second hydraulic cylinder is mounted on the upper surface of the second support. The output end of the second hydraulic cylinder movably penetrates the interior of the second support and is connected to the base plate. The leveling mechanism includes a second... A support frame is installed on one end of the upper surface of the workbench. Conveying rollers are movably installed on both sides of the upper end of the first support frame.

The scrapers are attached to the upper and lower sides of the raw material on the sides that are close to each other. The scraper ends away from the cutter are rounded. Tensioning rollers are movably installed at both ends of the first support frame. The raw material is located between the tensioning rollers, the conveying rollers, and the scrapers.

[0007] Preferably, a first hydraulic cylinder is mounted on the upper surface of the first bracket, a push plate is movably mounted on the upper interior of the first bracket, and positioning rods are respectively mounted on the opposite ends of the connecting plates. The positioning rods are respectively connected to the push plate and the worktable.

[0008] Preferably, a first guide rod is movably installed through both the front and rear ends of the upper surface of the first bracket, and the two ends of the first guide rod are connected to the push plate.

[0009] Preferably, the rounded corners of the scraper are covered with cushioning pads.

A spring is sleeved on the outer side of the rod of the second guide rod located between the upper surface of the slide block and the slide groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By setting up a leveling mechanism, the unevenness of raw materials caused by wrinkles, folds or uneven tension during the conveying process can be effectively solved. Then, the conveying roller provides stable power for the conveying of raw materials, ensuring that the raw materials move along the predetermined path. The tensioning roller, in conjunction with the spring, can flexibly adjust the tension of the raw materials during the conveying process, avoiding deformation or loosening of the raw materials due to excessive or insufficient tension, thus laying the foundation for subsequent leveling operations.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1 to 7 As shown, this utility model embodiment proposes a die-cutting machine with a leveling mechanism, including a worktable 1. A leveling mechanism 3 is installed at one end of the upper surface of the worktable 1. A second support 4 is installed at the end of the upper surface of the worktable 1 away from the leveling mechanism 3. A raw material 2 is installed between the leveling mechanism 3 and the worktable 1, and the raw material 2 is movably located at the lower end of the interior of the second support 4. A base plate 6 is installed at the lower end of the interior of the second support 4. A cutter 7 is installed on the lower surface of the base plate 6, and the cutter 7 and the raw material 2 overlap vertically. A second hydraulic cylinder 5 is installed on the upper surface of the second support 4. The output end of the second hydraulic cylinder 5 movably passes through the interior of the second support 4 and is connected to the base plate 6. The leveling mechanism 3 includes a first support 301. The bracket 301 is installed on one end of the upper surface of the workbench 1. Conveying rollers 302 are movably installed on both sides of the upper end of the first bracket 301. Connecting plates 303 are movably installed at the upper and lower ends of the first bracket 301, and the connecting plates 303 correspond one to one and overlap vertically. The connecting plates 303 are all inclined, and the inclination angles are opposite. Scrapers 304 are installed at the ends of the connecting plates 303 that are close to each other. The scrapers 304 are attached to the upper and lower sides of the raw material 2 on the sides that are close to each other. The end of the scraper 304 away from the cutter 7 is rounded. Tensioning rollers 313 are movably installed at both ends of the first bracket 301. The raw material 2 is located between the tensioning rollers 313, the conveying rollers 302 and the scrapers 304.

[0025] like Figures 4 to 7As shown, in another embodiment of this utility model, a first hydraulic cylinder 308 is mounted on the upper surface of the first support 301. A push plate 306 is movably mounted on the upper part of the interior of the first support 301. Positioning rods 305 are respectively mounted on the opposite ends of the connecting plates 303. The positioning rods 305 are respectively connected to the push plate 306 and the worktable 1. The output end of the first hydraulic cylinder 308 movably passes through the interior of the first support 301 and is connected to the push plate 306. First guide rods 307 are movably mounted through the front and rear ends of the upper surface of the first support 301. The opposite ends of the first guide rods 307 are connected to the push plate 306. The scraper 30... The rounded corners of 4 are covered with buffer pads. The two sides of the lower end of the first bracket 301 are respectively provided with sliding grooves 309. The sliding grooves 309 are respectively movably installed with sliders 310. The relatively overlapping sliders 310 are respectively installed with fixed rods 312. The tension roller 313 is movably installed through the outside of the rod body of the fixed rod 312. The two ends of the sliding groove 309 are respectively installed with second guide rods 311. The rod body of the second guide rod 311 is respectively movably installed through the inside of the slider 310. The outside of the rod body of the second guide rod 311 located between the upper surface of the slider 310 and the sliding groove 309 is respectively fitted with springs 314.

[0026] Under the elastic action of spring 314, tension roller 313 will adaptively adjust according to the tension changes during the conveying process of raw material 2. When the tension of raw material 2 is too large, spring 314 is compressed and tension roller 313 moves upward to reduce the pressure on raw material 2. When the tension of raw material 2 is too small, spring 314 returns to its original position and tension roller 313 moves downward to increase the pressure on raw material 2. This controls the tension during the conveying process of raw material 2. By flexibly adjusting the tension, the tension of raw material 2 is prevented from being stretched and deformed due to excessive tension or from being loose and wrinkled due to insufficient tension. This provides a stable state of raw material 2 for the subsequent leveling operation of leveling mechanism 3 and ensures the leveling effect.

[0027] The conveyor roller 302 starts to operate, driving the raw material 2 to move along a predetermined path between the leveling mechanism 3 and the second support 4. At the same time, the raw material 2 will first come into contact with the scraper 304 at the lower end. Then, according to the thickness of the raw material 2, the first hydraulic cylinder 308 is activated. The output end of the first hydraulic cylinder 308 pushes the push plate 306 to move. The push plate 306 drives the upper connecting plate 303 and the scraper 304 to move up and down through the positioning rod 305 until the upper and lower scrapers 304 are tightly in contact with the upper and lower sides of the raw material 2. This can adapt to raw materials 2 of different thicknesses and ensure that the scraper 304 always maintains a good contact state with the surface of the raw material 2. Then, during the continuous movement of the raw material 2, since the scraper 304 is inclined and the inclination angle is opposite, the rounded corner at the end away from the cutter 7, together with the buffer pad made of flexible material, will smoothly flatten the folded edge generated during the transportation of the raw material 2. Then, when the flat raw material 2 moves to the lower end of the second support 4, the second hydraulic cylinder 5 is activated, pushing the bottom plate 6 and the cutter 7 to move downward. The cutter 7 contacts the raw material 2 and completes the die-cutting operation.

[0028] The rounded corner design can prevent the edge of the scraper 304 from causing hard scratches to the raw material 2, while the buffer pad further reduces the impact force when the scraper 304 comes into contact with the raw material 2. It can effectively flatten the folded edge and protect the surface of the raw material 2 from damage, ensuring the integrity of the raw material 2.

[0029] In use, the conveyor roller 302 first starts operating, driving the raw material 2 to move along a predetermined path between the leveling mechanism 3 and the second support 4. At the same time, the raw material 2 will first come into contact with the scraper 304 at the lower end. Then, according to the thickness of the raw material 2, the first hydraulic cylinder 308 is activated. The output end of the first hydraulic cylinder 308 pushes the push plate 306 to move. The push plate 306 drives the upper connecting plate 303 and the scraper 304 to move up and down through the positioning rod 305 until the upper and lower scrapers 304 are tightly in contact with the upper and lower sides of the raw material 2. This can adapt to raw materials 2 of different thicknesses and ensure that the scraper 304 always maintains a good contact with the surface of the raw material 2. Then, during the continuous movement of the raw material 2, since the scraper 304 is inclined and the inclination angle is opposite, the rounded corner at the end away from the cutter 7, together with the buffer pad made of flexible material, will smoothly flatten the folded edge generated during the transportation of the raw material 2. Then, when the flat raw material 2 moves to the lower end of the second support 4, the second hydraulic cylinder 5 is activated, pushing the base plate 6 and the cutter 7 to move downward. The cutter 7 contacts the raw material 2 and completes the die-cutting operation.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
