[0002] Die-cutting is a cutting process in the post-processing of printed materials. It can cut printed materials or other paper products into cutting plates according to pre-designed graphics, so that the shape of printed materials is no longer limited to straight edges and right angles. Another type is die-cutting machines used for precision electronic die-cutting products. It is a comprehensive and complex cutting method that involves human resources, industrial equipment, industrial processes and management.

In existing cases, the products involve the combination of two separate objects. The black heat-insulating tape needs to have text printed on its surface and also needs to be die-cut into a fixed shape. Finally, precise alignment and nesting cutting are required to achieve the goal of saving material and thus developing the product and reducing costs. The process is cumbersome.

Detailed Implementation

[0026] The following is combined with Figure 1-2 This utility model will be described in detail.

[0027] A material-saving device for circular die-cutting includes a frame 10, with several die-cutting roller groups 20 arranged in the same horizontal direction on the frame 10; each die-cutting roller group 20 includes a circular die device and a support roller, the circular die device and the support roller cooperate to die-cut a strip of material, the strip of material is marked; and a scanning device 40, which is communicatively connected to the circular die device, scans the marks and transmits the actual position information of the marks to the circular die device; the circular die device adjusts its speed according to the difference between the actual position information of the scanning device 40 and the preset position.

[0028] Based on the positioning of the target, the areas where materials are not needed can be divided. In particular, for structural designs with shapes such as "islands" or "irregular shapes", the main parts can be cut into small areas of main materials, thereby saving the main materials in areas that are not needed and achieving the purpose of material saving.

[0029] The scanning device 40 is a photoelectric CCD lens, which can capture images of the mark. The circular knife body 202 can adjust its speed according to the difference between the actual position and the preset position of the mark.

[0030] In this embodiment, the circular die-cutting device includes a controller, which is communicatively connected to the scanning device 40 and receives position information transmitted by the scanning device 40. The controller is a processing unit such as a computer with certain calculation and judgment functions. The processing unit compares the actual position image of the mark captured by the photoelectric eye CCD lens with a preset position image and calculates the distance of the position difference between the two. Then, the position difference is converted into a corresponding speed adjustment command. The drive device adjusts the speed of the circular die body 202 according to the speed adjustment command to achieve a synchronization effect, thereby improving the die-cutting accuracy.

[0031] In this embodiment, the circular die device also includes a circular die body 202, which is connected to a drive device. The drive device is electrically connected to a controller to drive the circular die to rotate and adjust its speed. The drive device is a servo motor, and a photoelectric CCD lens faces the printed text strip, capturing the marked position of the printed text strip. The computer receives the reference point transmitted from the proximity switch and the photoelectric CCD lens, calculates the speed difference between the two, and controls the servo motor to make fine adjustments. The circular die body 202 is mounted on the output end of the servo motor, and its rotation speed is controlled by the servo motor. The feeding rollers feed the printed text strip.

[0032] Furthermore, it also includes a sensing device 205, which is communicatively connected to the controller. The sensing device 205 is used to measure the rotational speed of the circular cutter body 202. The sensing device 205 is a speed measuring device for measuring the rotational speed of the circular cutter body 202. The photoelectric CCD lens captures the marked position of the printed text strip on the latter, and the speed measuring device senses the rotational speed of the circular cutter. After the two devices are connected in parallel, the difference value is calculated by the computer background, and the data is sent back to the corresponding servo motor for adjustment. By maintaining the positional inconvenience, the speed of the subsequent feeding roller is adjusted to keep the feeding position consistent, ensuring that the printed text strip is cut in a loop on the circular cutter machine, and at the same time, the asynchronous pulling apart saves material and reduces costs.

[0033] Furthermore, the die-cutting roller assembly 20 includes a machine base 201, on which a circular blade body 202, a first support roller 203, and a second support roller 204 are arranged sequentially from top to bottom. The circular blade and the first support roller 203 cooperate to die-cut the material strip; the first support roller 203 and the second support roller 204 cooperate to convey the material strip.

[0034] Furthermore, the machine base 201 is provided with a sliding groove and a clamping device that respectively cooperate with both ends of the circular cutter. The sliding groove is arranged vertically, and the clamping device is located above the circular cutter. Furthermore, the clamping device includes a pressure block 501 and a fastener 502 for adjusting the pressure of the pressure block 501 on the circular cutter. The lower end of the fastener 502 cooperates with the pressure block 501, and the pressure block 501 abuts against the circular cutter. The clamping device also includes a mounting plate 503 that is movably connected to the fastener 502. The fastener 502 passes through the mounting plate 503 and is connected to the pressure block 501.

[0035] Furthermore, the frame 10 has a receiving mechanism at the same horizontal position above the die-cutting roller group 20; the receiving mechanism includes a plurality of receiving roller groups 30 that cooperate with the plurality of die-cutting roller groups 20. Furthermore, the machine base 201 has a guide roller that cooperates with the receiving mechanism on the side near the receiving mechanism.

[0036] The material-saving device for circular die-cutting according to this utility model is used as follows:

[0037] The material strip carries the product to be die-cut. Marks can be placed on the material strip or on the product. The material strip feeds towards the circular die at a certain speed. The circular die cuts the product. The CCD lens of the photoelectric sensor can capture images of the marks, similar to tracking or trailing images. After capturing the images, the actual position of the marks is compared with the preset position. If the two coincide, the material strip's feed speed meets the requirements and is synchronized. If the two do not coincide, the material strip's feed speed does not meet the requirements and is out of sync, either too fast or too slow. Then, based on the difference between the actual position and the preset position of the marks, the rotation speed of the circular die is adjusted to achieve or approach synchronization, allowing the circular die to more accurately die-cut the product, improving the die-cutting quality. In particular, for secondary die-cutting, it can enable the material strip to feed synchronously, improving the accuracy and quality of secondary die-cutting, and also facilitating asynchronous material saving.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
