Abstract
Description
Technical Field
[0001] This utility model belongs to the field of die-cutting equipment technology, specifically relating to a device for marking small holes in perforated transparent film waste and a die-cutting production line. Background Technology
[0002] Die cutting is a processing technology that uses molds (dies) to stamp, cut, crimp, or shape materials. It is now widely used in industries such as packaging, printing, electronics, automobiles, and medical.
[0003] In die-cutting processes, waste removal is a crucial operation. Waste removal refers to the process of separating and removing excess waste materials (such as edges, hole chips, and scraps) generated after cutting from the product. The effectiveness of waste removal directly affects product yield and production efficiency, especially in high-precision electronic die-cutting (such as protective films and adhesive products), where residual waste can lead to a decrease in product yield.
[0004] Currently, waste removal for die-cutting of transparent substrates with small holes is mostly achieved through self-suction. However, this operation is prone to insufficient suction in some areas, resulting in residue. Furthermore, the transparent protective film (such as PET and PE) is prone to static electricity, which can cause waste to re-adhere during transportation. Because the waste that is not effectively removed has the same color and light transmittance as the protective film, it is difficult to identify by the naked eye or ordinary optical inspection, leading to a high risk of missed detection. This waste may flow into the customer's possession along with the product, causing losses. Therefore, this invention provides a perforated transparent film material waste marking device to solve the above problems. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] Example 1
[0028] This utility model embodiment provides a perforated transparent film material waste marking device, including a waste marking mechanism 3, which is distributed upstream of a die-cutting mechanism 5. The waste marking mechanism 3 includes a marking die 7 and marking tape. The marking position of the marking die 7 is the same as the die-cutting position of the die-cutting mechanism 5, and the size of the marking die 7 is smaller than the size of the die-cutting die 8 in the die-cutting mechanism 5. The die-cutting range of the die-cutting die 8 can cover the marking range of the marking die 7. The marking tape has color or pattern, which can form a sharp contrast with the transparent film material, making it easy to quickly and accurately identify the marking tape from the transparent film material. The marking tape can be die-cut by the marking die 7, and the die-cut markings can be attached to the die-cutting position of the transparent film material. The die-cutting die 8 of the die-cutting mechanism 5 can die-cut the marked transparent film material and remove waste.
[0029] In this embodiment, as Figures 1-3 As shown, the die-cutting die 8 of the die-cutting mechanism 5 has a circular blade with a diameter of 2mm, and there are two blades. The marking die 7 also has a circular blade, but its diameter is smaller than that of the die-cutting die 8 (1.5mm), and there are also two marking dies. This embodiment can be used for auxiliary waste removal of transparent film materials with two small holes.
[0030] In addition, this device is equipped with an input component and an output component for labeling tape. The input component is used to feed the labeling tape into the labeling die 7 for die-cutting, and the output component is used to discharge the die-cut tape. The input and output components have identical structures, each including at least one conveyor roller (labeling tape feed shaft 6), which is rotatably mounted on a fixed frame (not shown in the figure). The labeling tape is wound around the conveyor rollers at the input and output positions, respectively, for winding and unwinding. Alternatively, one or more conveyor rollers can be placed between the input and output positions to support the labeling tape and achieve stable movement. The input structure for transparent film material is the transparent film feed shaft 1. The output structure is not shown in the figure.
[0031] The operating principle of this device is as follows:
[0032] In application, the transparent film and the colored marking tape enter the marking die 7 station. The marking die 7 cuts the marking tape. The colored tape with a diameter of 1.5mm is attached to the die-cut position of the transparent film to mark the die-cut position of the transparent film. The remaining colored tape is discharged through the marking tape output component.
[0033] The transparent film material marked with colored tape moves to the die-cutting station. Die-cutting die 8 cuts the transparent film material, forming a 2mm diameter through hole at the die-cutting position. The 2mm diameter circular transparent film material is then coated with a 1.5mm diameter circular piece of colored tape. A self-suction die removes the waste, separating the 2mm circular transparent film material and the 1.5mm circular piece of colored tape from the die-cut transparent film material. If the self-suction die does not completely remove the tape, the colored markings are not separated. However, due to the obvious color difference between the colored tape and the transparent film material, workers can easily identify the incompletely removed areas, thus eliminating defects. This solves the problem of waste leakage and difficulty in identification in existing technologies, greatly improving production quality and efficiency.
[0034] Example 2
[0035] The main structure of this embodiment is the same as that of embodiment 1, except that the structure of the marking die 7 and the die-cutting die 8 is defined in this embodiment.
[0036] Specifically, the marking die 7 is a flat die ( Figure 2 The die-cutting mechanism 5 includes a substrate and a blade, with the substrate positioned directly above the anvil and the blade positioned below the substrate. The die-cutting die 8 of the die-cutting mechanism 5 is a self-priming flat blade. Figure 3 The device includes a substrate and a blade, with the substrate positioned directly above the cutting board. A cavity is formed within the substrate, and a self-priming hole communicating with the cavity is located on the lower surface of the substrate, with the edge of the self-priming hole extending downwards to form the blade. A negative pressure device is installed on the substrate to provide a negative pressure environment for the cavity.
[0037] This embodiment is applicable to the die-cutting process of transparent film materials with high hardness.
[0038] Example 3
[0039] The main structure of this embodiment is the same as that of embodiment 1, except that the structure of the marking die 7 and the die-cutting die 8 is defined in this embodiment.
[0040] Specifically, the marking die 7 is a circular die ( Figure 4 The die-cutting mechanism 5 includes a steel roller and a rubber roller with blades, arranged vertically and rotating in the same direction. The die-cutting die 8 of the die-cutting mechanism 5 is a self-priming circular die, also consisting of a steel roller and a rubber roller with blades, arranged vertically and rotating in the same direction. The steel roller is a hollow cavity with self-priming holes communicating with the cavity on its surface, the edges of which extend outwards to form cutting edges. A negative pressure device is installed on the steel roller to provide a negative pressure environment for the hollow cavity.
[0041] This embodiment is applicable to the die-cutting process of transparent film materials with low hardness.
[0042] Example 4
[0043] The main structure of this embodiment is the same as that of embodiment 1, the difference being:
[0044] This embodiment also includes a leveling mechanism 2 and a pressing mechanism 4.
[0045] Specifically, the leveling mechanism 2 is located upstream of the waste marking mechanism 3 and is used for leveling the transparent film. The pressing mechanism 4 is located between the waste marking mechanism 3 and the die-cutting mechanism 5 and is used for the stable pressing of the transparent film and the marking.
[0046] The leveling mechanism 2 and the pressing mechanism 4 have the same structure, both including a rubber roller and a bottom roller. The rubber roller and the bottom roller are distributed vertically and are rotatably mounted on the fixed frame via a rotating shaft. The rotation directions of the rubber roller and the bottom roller are the same.
