Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a die-cutting waste removal structure, a die-cutting machine, and self-adhesive labels produced therefrom. Background Technology

[0002] During the die-cutting process, excess mesh waste edges need to be removed after die-cutting the material. For example, Chinese utility model patent CN213010979U discloses a waste edge recycling structure for die-cutting machines, which achieves waste material recycling and separation from the backing paper by wrapping the mesh waste edges around a waste edge recycling roller. However, this waste removal method not only generates a lot of waste, but also results in large gaps between labels, leading to serious material waste and high production costs.

[0003] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a patent name to solve the problems of excessive waste and large label gaps in the waste discharge method of the existing die-cutting machine, which leads to material waste and high costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting waste removal structure, including a frame, a first bending plate installed on the frame, a first guide roller installed on the side of the frame above the first bending plate and a second guide roller installed below the frame, a waste removal mechanism provided on the side of the first bending plate away from the first guide roller, capable of separating the die-cut waste material from the base paper, and a waste collection mechanism provided between the first guide roller and the second guide roller on the frame for collecting the waste material.

[0006] By adopting the above technical solution, the material is guided and bent by the first guide roller and the second guide roller in conjunction with the first bending plate, so that the edge of the die-cut label paper waste can be lifted from the base paper. This makes it convenient for the waste removal mechanism to selectively remove the die-cut individual waste pieces from the base paper. The waste collection mechanism can collect the removed waste in a timely manner, which changes the traditional mesh waste edge winding recycling mode. Only a small portion of the label paper needs to be die-cut from the material and discharged as waste, which can then be used as the recognition position of the label printer. Therefore, it can effectively reduce the amount of waste generated, while also reducing the gap between labels and reducing material waste, thereby significantly reducing production costs.

[0007] A further setting of the above technical solution is as follows: the waste removal mechanism includes a first air blowing main pipe installed on the frame and a first air blowing device connected to the first air blowing main pipe. The first air blowing main pipe is connected to a first air blowing branch pipe with the same number of waste columns after die-cutting of the material. The first air blowing branch pipe is provided with a first air outlet at one end near the first bending plate. The first air outlet is aligned with the position of the waste after die-cutting on the material.

[0008] Using the above technical solution, the first blowing device generates airflow, which is distributed to each of the first blowing branch pipes through the first blowing main pipe, and then accurately blown from the first air outlet to the corresponding column of waste on the material, which can efficiently blow the waste off the bottom paper and ensure the waste removal effect.

[0009] A further configuration of the above technical solution is as follows: the waste collection mechanism includes a collection hopper mounted on the frame, a dust collection device communicating with the bottom of the collection hopper, and a mesh cover mounted on the frame. The upper end of the collection hopper extends to the lower part of the first bending plate near one side edge, and the mesh cover is located above the collection hopper.

[0010] Using the above technical solution, the dust collection device generates negative pressure when working, which can suck the waste material blown off the bottom paper into the collection hopper for collection. The mesh cover can prevent the waste material from splashing during the collection process, ensuring the stability and cleanliness of waste material collection, and avoiding secondary pollution or additional waste caused by waste material scattering.

[0011] A further provision of the above technical solution is that a first sensor frame is installed on the frame, and a first detection sensor with the same number of waste columns as the material after die-cutting is installed on the first sensor frame.

[0012] Using the above technical solution, the first detection sensor can detect the position and status of each column of waste in real time. When it detects that the waste has been transported to the waste removal position or that there is an abnormality in the waste removal process, it can provide timely feedback, which will help staff to discover and deal with the problem in a timely manner and ensure the continuity and reliability of the waste removal process.

[0013] A further configuration of the above technical solution is as follows: the frame is located at the end of the second guide roller away from the first bending plate, and a second blowing main pipe and a second sensor frame are also installed. The second blowing main pipe is connected to a second blowing device. A second blowing branch pipe with the same number of waste columns after die-cutting is connected to the second blowing main pipe. A second air outlet is provided at the end of the second blowing branch pipe near the second bending plate. The second air outlet is aligned with the position of the waste column after die-cutting on the material. A second detection sensor with the same number of waste columns after die-cutting is installed on the second sensor frame. A third guide roller is installed below the second bending plate on the frame.

[0014] Using the above technical solution, the second bending plate, the second main air blowing pipe, the second branch air blowing pipe and other structures form a secondary waste removal process. The second detection sensor works in conjunction to realize secondary detection, which can further process and detect any waste that may remain on the material, thereby improving the success rate of waste removal and ensuring production quality. The third guide roller works in conjunction with the second bending plate to guide and bend the material so that the edge of the waste can be lifted off the bottom paper, making it easier to be blown away.

[0015] A further configuration of the above technical solution is as follows: the first guide roller is located on the side below the first bending plate, close to the second guide roller, and the third guide roller is located on the side below the second bending plate, close to the second guide roller.

[0016] By adopting the above technical solution, the bending angle of the material at the first bending plate and the second bending plate can be larger, making it easier for the edge of the waste to be lifted, thereby further improving the success rate of waste removal.

[0017] A die-cutting machine, comprising the die-cutting waste removal structure described in any of the above claims.

[0018] By adopting the above technical solution, the die-cutting machine, after integrating the die-cutting waste removal structure, can be directly applied to the production and processing of self-adhesive labels. It can inherit the advantages of the waste removal structure in reducing waste and narrowing the gap between labels, thereby reducing material waste in the production process and reducing production costs as a whole.

[0019] A self-adhesive label includes a backing paper and a label paper. The back of the label paper is coated with self-adhesive and the label paper is attached to the backing paper by the self-adhesive. The label paper has a plurality of evenly spaced slits, and the outer periphery of the label paper has a notch for the label printer to identify the position. The self-adhesive label is produced by the aforementioned die-cutting machine.

[0020] Using the above technical solution, the notches on the label paper facilitate the subsequent separation of individual labels from the backing paper, and the notches help the label printer accurately identify the position of the label paper, ensuring the accuracy of the printed content; the small gaps between the label papers greatly reduce material waste and lower production costs.

[0021] A further provision of the above technical solution is that the notch is located at one corner of two adjacent label papers and is cut in two.

[0022] By adopting the above technical solution, the notch is set at one corner of two adjacent label papers and separated by a cut. A single notch can simultaneously assist the printing positioning of two adjacent label papers, effectively improving the utilization rate of the notch. Moreover, the cut separation will not affect the subsequent normal separation of the label papers and has little impact on label printing, further optimizing the label structure design.

[0023] A further feature of the above technical solution is that the bottom of the notch is rounded.

[0024] By adopting the above technical solution, the rounded corner design at the bottom of the notch can prevent tearing caused by stress concentration at the bottom of the notch, and it is also more aesthetically pleasing.

[0025] The beneficial effects achieved by this utility model are as follows: the die-cutting waste removal structure, through the precise waste removal mechanism and the efficient collection mechanism, combined with the stable conveying of multiple guide rollers and the real-time detection of sensors, greatly reduces the amount of waste discharged; the self-adhesive labels produced by the die-cutting machine with this waste removal method not only have small gaps between the label papers, but also have an optimized label structure, which can greatly save materials and significantly reduce production costs.

A first guide roller 3 is mounted on the side of the frame 1 above the first bending plate 2, and a second guide roller 4 is mounted below the frame 1. The first guide roller 3 is located on the side below the first bending plate 2, closer to the second guide roller 4. A waste removal mechanism 5 is provided on the side of the first bending plate 2 away from the first guide roller 3, which can remove the die-cut waste pieces from the base paper. The waste removal mechanism 5 includes a first air blowing main pipe 51 mounted on the frame 1 and a first air blowing device (not shown in the figure) connected to the first air blowing main pipe 51. A first air blowing branch pipe 52 with the same number of rows of die-cut waste pieces is connected to the first air blowing main pipe 51. A first air outlet 53 is provided on the end of the first air blowing branch pipe 52 near the first bending plate 2, and the first air outlet 53 is aligned with the position of the die-cut waste pieces on the material. like Figure 1-5 As shown, a waste collection mechanism 6 for collecting waste material is provided between the first guide roller 3 and the second guide roller 4 on the frame 1. The waste collection mechanism 6 includes a collection hopper 61 mounted on the frame 1, a dust collection device (not shown) communicating with the bottom of the collection hopper 61, and a mesh cover 62 mounted on the frame 1. The upper end of the collection hopper 61 extends to the lower part of the first bending plate 2 near one side edge, and the mesh cover 62 is located above the collection hopper 61. A first sensor frame 7 is mounted on the frame 1, and a first detection sensor 8 with the same number of rows of waste material after die-cutting is mounted on the first sensor frame 7. like Figure 1-5 As shown, the frame 1 is located at the end of the second guide roller 4 away from the first bending plate 2 and is also equipped with a second bending plate 9, a second air blowing main pipe 10 and a second sensor frame 11. The second air blowing main pipe 10 is connected to a second air blowing device (not shown in the figure). The second air blowing main pipe 10 is connected to a second air blowing branch pipe 12 with the same number of waste columns after die-cutting of the material. The second air blowing branch pipe 12 is provided with a second air outlet 13 at the end near the second bending plate 9. The second air outlet 13 is aligned with the position of the waste column after die-cutting on the material. The second sensor frame 11 is equipped with a second detection sensor 14 with the same number of waste columns after die-cutting of the material. The frame 1 is located below the second bending plate 9 and is equipped with a third guide roller 15. The third guide roller 15 is located below the second bending plate 9 on the side near the second guide roller 4. To achieve the aforementioned blowing function, the first and second blowing devices are specifically blowers; correspondingly, to achieve the aforementioned dust collection function, the dust collection device is specifically a vacuum cleaner.

[0030] A die-cutting machine includes the die-cutting waste removal structure described above. This die-cutting machine can be directly used for the production and processing of self-adhesive labels. The integrated waste removal structure reduces waste and material waste. like Figure 6 , 7 As shown, a self-adhesive label includes a backing paper 16 and a label paper 17. The back of the label paper 17 is coated with self-adhesive and the label paper 17 is attached to the backing paper 16 by the self-adhesive. Several slits 18 are evenly spaced on the label paper 17. A notch 19 for the label printer to identify the position is opened at the outer peripheral edge of the label paper 17. The notch 19 is located at one corner of two adjacent label papers 17 and is divided in two by the slits 18. The bottom of the notch 19 is rounded. The self-adhesive label is produced by the above-mentioned die-cutting machine. In the above embodiment, after the die-cutting machine cuts the notch in the label, it drives the material to pass through the first guide 3, the first bending plate 2, the second guide roller 4, the second bending plate 9 and the third guide roller 15 in sequence for conveying. The first blowing device is activated, and the airflow passes through the first blowing main pipe 51 and the first blowing branch pipe 52 and blows the waste material from the first air outlet 53, causing the waste material to detach from the backing paper. At the same time, the dust suction device generates negative pressure, sucking the detached waste material into the collection hopper 61 and collecting it. The mesh cover 62 can prevent the waste material from splashing. The second blowing device is activated, and the airflow passes through the second blowing main pipe 10 and the second blowing branch pipe 12 and blows away the residual waste material from the second air outlet 13. The first detection sensor 8 and the second detection sensor 14 can detect whether there is residual waste material on the material during the two waste discharge processes, respectively. The two waste discharges can greatly ensure the success rate of waste discharge. After waste discharge, the die-cutting machine performs horizontal die-cutting on the material again to separate the label paper. The self-adhesive labels produced by this die-cutting machine have small gaps between the label sheets and a stable label sheet structure. The overall production process reduces material waste and lowers production costs.
