Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a die-cutting machine for label production. Background Technology

[0002] In the label production process, the die-cutting machine plays a core role in label processing. Currently, when a die-cutting machine is in operation, the label goes through multiple processes from feeding to finished product recycling. Due to the thinness of the label and its susceptibility to equipment vibration and roller tension during transport, positional shifts can easily occur as the label moves between different processing stages. If the label's position is not properly controlled, inaccurate positioning before entering the die-cutting stage may result in labels that do not meet the required size and shape. Furthermore, if subsequent calibration and transport of the die-cut finished product fail to correct positional deviations, it will cause problems for finished product recycling, leading to uneven stacking of recycled labels, increased subsequent handling costs, and impacting overall production efficiency and product quality.

[0003] Therefore, it is necessary to propose a new solution to address the aforementioned problems. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A die-cutting machine for label production includes a body, a feeding mechanism, a first limiting component, a first conveying roller group, a second limiting component, a die-cutting mechanism, a third limiting component, a second conveying roller group, and a finished product recycling mechanism, which are sequentially arranged along the label conveying direction of the body.

[0017] The second positioning scale plate is fixed to the machine body along the label conveying path. It shows that there are four second guide slots symmetrically distributed in two rows, and its scale is located on the side of one of the rows of second guide slots, and increases towards both ends with the center line of the row of second guide slots as the reference.

[0018] There are four second sliding lock seats, each embedded in one of the four second guide slots and slidably adapted. The two longitudinally corresponding second sliding lock seats are connected by a connecting block. The second adjusting screw passes through the second sliding lock seat and is screwed into the second clamping block, so that the second sliding lock seat and the second clamping block form a slidingly adjustable limiting structure on the second positioning scale plate.

[0019] As a further embodiment of this utility model: the two longitudinally corresponding second sliding lock seats and their corresponding connecting blocks are provided with a continuous second limiting groove that is adapted to the side of the label.

[0020] As a further embodiment of this utility model: the first conveying roller group and the second conveying roller group each include an upper pressure roller, a lower pressure roller and a spacing adjustment component. The upper pressure roller and the lower pressure roller are arranged in parallel and connected to the machine body through a bracket. The spacing adjustment component is used to adjust the spacing between the upper pressure roller and the lower pressure roller.

[0031] 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.

[0032] Please see Figure 1-4In this embodiment of the present invention, a die-cutting machine for label production includes a body 1, a feeding mechanism 2, a first limiting component 3, a first conveying roller group 4, a second limiting component 5, a die-cutting mechanism 6, a third limiting component 7, a second conveying roller group 8, and a finished product recycling mechanism 9, which are sequentially arranged on the body 1 along the label conveying direction.

[0033] The feeding mechanism 2 is used to transport label raw materials;

[0034] The first limiting component 3 is used to initially limit the label material in front of the first conveying roller group 4;

[0035] The second limiting component 5 is used to perform secondary limiting on the label material conveyed by the first conveying roller group 4;

[0036] The die-cutting mechanism 6 is used to die-cut the label material that has been constrained twice.

[0037] The third limiting component 7 is used to continuously calibrate and limit the die-cut label product;

[0038] The finished product recycling mechanism 9 is used to recycle the finished labels after they have been conveyed by the second conveyor roller group 8.

[0039] In the above technical solution, the feeding mechanism 2, the first limiting component 3, the first conveying roller group 4, the second limiting component 5, the die-cutting mechanism 6, the third limiting component 7, the second conveying roller group 8 and the finished product recycling mechanism 9 arranged in sequence along the label conveying direction work together closely to achieve precise processing of the label from raw material to finished product.

[0040] The feeding mechanism 2 typically consists of an unwinding roller, a guide roller, and a tension adjusting device. The unwinding roller holds the label material roll, the guide roller guides the conveying path, and the tension adjusting device controls the tension of the material release to prevent slack or stretching deformation, ensuring that the material smoothly enters the first limiting component 3. The first limiting component 3 and the second limiting component 5 perform initial and secondary limiting calibrations on the label material, and then the first conveying roller group 4 clamps and conveys the label to the second limiting component 5. The first limiting component 3 and the second limiting component 5 are set before and after the first conveying roller group 4 because the label raw material may be offset due to factors such as tension fluctuations and equipment vibration during the conveying process of the feeding mechanism 2. The first limiting component 3 can perform initial positioning of the label before entering the first conveying roller group 4, that is, perform initial positioning of the label conveyed by the feeding mechanism 2 to initially correct the offset. Although the first conveying roller group 4 can ensure stable label conveying during the conveying process through the cooperation of the upper and lower pressure rollers and the adjustment of the spacing, there may still be slight offset. The second limiting component 5 can perform secondary limiting calibration of the label output from the first conveying roller group 4 to ensure that the label entering the die-cutting mechanism 6 is accurately positioned, thereby improving the die-cutting processing accuracy.

[0041] The first conveying roller group 4 and the second conveying roller group 8 are generally composed of a drive roller, a driven roller and a spacing adjustment component. The drive roller provides conveying power, the driven roller assists in pressing the label, and the spacing adjustment component can manually or electrically adjust the spacing between the upper and lower pressure rollers through a screw-nut or slide rail slider structure to adapt to labels of different thicknesses, ensure stable conveying and avoid label damage or slippage.

[0042] The labels, after being limited by a second set of stops, enter the die-cutting mechanism 6 for processing. The die-cutting mechanism 6 typically consists of a die, a drive unit, and a pressure mechanism. The die is customized according to the shape of the finished label; common types include flatbed die-cutting dies and rotary die-cutting dies. The drive unit is usually motor-driven, moving the die through a transmission mechanism. The pressure mechanism provides sufficient pressure to allow the die to cut or indent the label material according to a predetermined shape, completing the die-cutting process. The die-cut finished product is continuously calibrated and limited by a third set of stop components 7 to eliminate any offset caused by die-cutting. Finally, it is conveyed by a second set of conveying rollers 8 to the finished product recycling mechanism 9. The finished product recycling mechanism 9 typically consists of a combination of a take-up roller and a counting device. The take-up roller, driven by a motor, rotates to neatly wind the finished labels, while the counting device monitors the number of labels in real time.

[0043] By using three precise positioning steps, the system effectively reduces the positional deviation of labels during feeding, die-cutting, and recycling, thereby lowering the rate of defective sizes and shapes caused by inaccurate positioning and ensuring the consistency of die-cut labels.

[0044] In this embodiment of the present invention, the first limiting component 3 and the second limiting component 5 each include a first positioning scale plate 10, a first adjusting screw 11, a first sliding lock seat 12 and a first clamping pressure block 13.

[0045] The first positioning scale plate 10 is fixed to the machine body 1 along the label conveying path. Its surface is provided with first guide grooves 14 and is symmetrically distributed. Its scale scale increases from the center line of the two symmetrical first guide grooves 14 to both ends.

[0046] The first sliding lock seat 12 is embedded in the first guide groove 14 and can be slidably adapted. The first adjusting screw 11 passes through the first sliding lock seat 12 and is screwed into the first clamping pressure block 13, so that the first sliding lock seat 12 and the first clamping pressure block 13 form a slidingly adjustable limiting structure on the first positioning scale plate 10.

[0047] The first positioning scale plate 10 is fixed along the label conveying path. The first guide grooves 14 symmetrically distributed on its surface provide a sliding track for the first sliding lock seat 12. The operator can manually adjust the position of the two first sliding lock seats 12 according to the label width and with reference to the scale increments based on the center line of the guide groove. Then, the operator can rotate the first adjusting screw 11 to lock the first clamping block 13 with the first sliding lock seat 12, fixing the first sliding lock seat 12 in the preset position of the first positioning scale plate 10, so that a stable channel is formed between the two symmetrical first sliding lock seats 12. The label material is conveyed in this channel. The label offset is limited by the limiting effect of the first sliding lock seat 12 relative to the inner side wall, ensuring that the label position is accurate when entering the subsequent process, laying the foundation for die-cutting. Moreover, the flexible adjustment of the spacing of the first sliding lock seats 12 can adapt to the limiting requirements of labels of different widths.

[0048] In this embodiment of the utility model, two first sliding lock seats 12 are symmetrically arranged, and each of the two first sliding lock seats 12 has a first limiting groove 21 adapted to the side of the label on its inner sidewall.

[0049] Two symmetrical first sliding lock seats 12 slide and adjust along the guide groove of the first positioning scale plate 10, and use the first limiting slots 21 on their relatively inner sidewalls that are adapted to the side of the label to form a double constraint on the label during transportation. When the side of the label is embedded in the slot, the contour of the slot fits with the side of the label, restricting the lateral displacement of the label outside the transportation direction, while not interfering with the movement of the label along the transportation direction. Precise positioning is achieved through physical structural adaptation, ensuring that the label enters the subsequent process in a stable posture.

[0050] In this embodiment of the present invention, the third limiting component 7 includes a second positioning scale plate 15, a second adjusting screw 16, a second sliding lock seat 17, and a second clamping pressure block 18.

[0051] The second positioning scale plate 15 is fixed to the machine body 1 along the label conveying path. It shows that there are four second guide slots 19 arranged in two rows symmetrically, and its scale is located on the side of one row of second guide slots 19, and increases towards both ends with the center line of the row of second guide slots 19 as the reference.

[0052] There are four second sliding lock seats 17, which are respectively embedded in four second guide slots 19 and can be slidably adapted. The two longitudinally corresponding second sliding lock seats 17 are connected by a connecting block 20. The second adjusting screw 16 passes through the second sliding lock seat 17 and is screwed into the second clamping block 18, so that the second sliding lock seat 17 and the second clamping block form a slidingly adjustable limiting structure on the second positioning scale plate 15.

[0053] The second positioning scale plate 15 is fixed along the label conveying path. Its surface has four second guide grooves 19 arranged in two rows symmetrically, providing sliding tracks for the four second sliding lock seats 17. The operator can manually adjust the position of the four second sliding lock seats 17 (two longitudinally corresponding second sliding lock seats 17 are connected by the connecting block 20 and move synchronously during adjustment) according to the width of the die-cut label and calibration requirements, with the scale increments based on the center line of one row of second guide grooves 19. Rotating the second adjusting screw 16 causes the second clamping pressure block 18 to cooperate with the second sliding lock seats 17, fixing the second sliding lock seats 17 in the preset position of the second positioning scale plate 15. The four second sliding lock seats, together with the connecting block 20 and the second clamping pressure block 18, surround the label from both sides, limiting its lateral displacement. The flexible adjustment of the spacing between the two second sliding lock seats 17 in the same row (with the help of the connecting block 20 and the scale) adapts to the calibration requirements of labels of different widths.

[0054] The connecting block 20 and the two corresponding second sliding lock seats 17 in the longitudinal direction form a linkage unit, which can not only adapt to different size labels, but also continuously calibrate the label posture, ensuring that the label enters the finished product recycling mechanism 9 in a regular state, laying the foundation for subsequent efficient winding and packaging.

[0055] In this embodiment of the utility model, the two longitudinally corresponding second sliding lock seats 17 and their corresponding connecting blocks 20 are provided with a continuous second limiting groove 22 that is adapted to the side of the label.

[0056] The two longitudinally corresponding second sliding locking seats 17 cooperate with the connecting block 20 to form a continuous second limiting groove 22, which adapts and constrains the side of the finished label during transport. The contour of the second limiting groove 22 matches the side of the label. When the label moves along the transport path, it is inserted into the second limiting groove 22 from the side. The physical shape of the second limiting groove 22 restricts the lateral displacement of the label, while not hindering its longitudinal transport. The structural adaptation achieves precise and continuous calibration and limiting.

[0057] The connecting block 20 rigidly connects the longitudinally corresponding second sliding lock seats 17 to form a cooperatively adjustable limiting unit, which is the key to achieving continuous calibration of the limiting position. During the label conveying process, the connecting block 20 ensures that the longitudinally corresponding second sliding lock seats 17 always maintain synchronous displacement. When the second adjusting screw 16 is rotated to adjust the spacing of the second sliding lock seats 17, the connecting block 20 drives the corresponding second sliding lock seats 17 to slide synchronously, so that the continuous second limiting slot 22 always fits the side of the label. Even if the label shifts due to vibration or tension changes during conveying, the second limiting slot 22 can respond and correct in real time, avoiding limiting failure caused by asynchronous displacement of a single second sliding lock seat 17, thereby achieving stable constraint on the label from entering to leaving the third limiting component 7.

[0058] It is understood that the number of the second adjusting screw 16 and the second clamping block 18 is the same as the number of the second sliding lock seat 17, and the number of the first adjusting screw 11 and the first clamping block 13 is the same as the number of the first sliding lock seat 12.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
