Description

Technical Field

[0001] This utility model relates to the field of precision die-cutting technology, specifically a waste processing film for isolated waste materials and its die-cutting waste removal device. Background Technology

[0002] The current die-cutting process basically involves a carrier tape (protective film), on which various main materials (product films) are laminated and die-cut. Waste is generally divided into two types: continuous waste, which can be continuously pulled, rolled up and discharged; and isolated waste, such as waste with round holes. The waste is in the form of isolated islands and cannot be discharged directly. Waste discharge tape is needed to stick the waste to the tape before rolling it up and pulling it out. However, because the carrier tape itself has a certain degree of stickiness, the waste and the carrier tape are stuck together. Therefore, there is a certain probability of waste being missed when using tape to discharge isolated waste. Utility Model Content

[0003] The purpose of this invention is to provide a waste processing membrane for isolated islands and its die-cutting and waste removal device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An island waste processing membrane includes a product membrane and a protective film located outside the product membrane. Both the protective film and the inner side of the product membrane are adhesive surfaces. A shielding film is disposed between the protective film and the product membrane, and the protective film is connected to the product membrane through the shielding film.

[0005] As a further aspect of this invention, the shielding film is discrete.

[0006] As a further improvement of this invention, the shielding film is continuous.

[0007] A die-cutting and waste removal device for processing the aforementioned isolated waste material includes a base plate, on which a plurality of height adjustment components are fixedly connected. A central shaft is rotatably connected to each height adjustment component. A die-cutting component and a waste removal auxiliary component are fixedly connected to the base plate. The waste removal auxiliary component is located above the waste removal tape. The waste removal auxiliary component rises and falls synchronously with the die-cutting component and squeezes the waste removal tape and the isolated waste material.

[0008] As a further embodiment of this utility model: the height adjustment component includes a fixed bracket, a first slider is longitudinally slidably connected to the fixed bracket, an adjusting screw is rotatably connected to the fixed bracket, the first slider is threadedly connected to the adjusting screw, and the central shaft is rotatably connected to the first slider.

[0009] As a further embodiment of this utility model: the die-cutting assembly includes a telescopic drive component fixed below the base plate, a second slider is fixedly connected to the piston rod of the telescopic drive component, a connecting rod for connecting the die-cutting tool is connected to the second slider, a guide seat is fixedly connected to the base plate, and the second slider is slidably connected to the guide seat.

[0010] As a further embodiment of this utility model: a horizontal telescopic rod is fixedly connected to the side of the second slider, and a waste discharge auxiliary component is connected to the end of the horizontal telescopic rod. The waste discharge auxiliary component includes a pressure rod fixedly connected to the end of the horizontal telescopic rod, and a pressure block connecting sleeve is slidably connected to the outside of the pressure rod. When the pressure block connecting sleeve is pressed down, the pressure block at the bottom presses the waste discharge tape against the isolated waste material.

[0011] As a further embodiment of this utility model: a transverse sliding groove is fixedly connected to the base plate, a longitudinal sliding groove is slidably connected within the transverse sliding groove, and the pressure rod is slidably connected to the longitudinal sliding groove.

[0012] Compared with existing technologies, the advantages of this invention are: This invention has a simple structure. By setting a shielding film between the product film and the protective film, the processing area of ​​the product film is not directly adhered to the protective film. The shielding film significantly improves the waste removal efficiency of isolated waste materials. Furthermore, the matching waste removal auxiliary components ensure more thorough waste removal, preventing waste removal failure due to insufficient adhesion of the waste removal tape.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 and Figure 2A waste processing membrane for isolated waste and its die-cutting waste removal device are disclosed. The membrane includes a product membrane 1 and a protective membrane 2 located outside the product membrane 1. Both the protective membrane 2 and the inner surface of the product membrane 1 are adhesive. During die-cutting on the product membrane 1, conventional waste removal tape often results in a significant amount of isolated waste adhering to the protective membrane 2, preventing its removal. A shielding membrane 3 is positioned between the protective membrane 2 and the product membrane 1. The shielding membrane 3 prevents the protective membrane 2 from adhering to the processing position of the product membrane 1, thus achieving efficient waste removal. The outer dimensions of the shielding membrane 3 are normally smaller than those of the product membrane 1 and the protective membrane 2. Therefore, the protective membrane 2 can connect to the product membrane 1 through the shielding membrane 3. The shielding membrane 3 can be discrete or continuous. When discrete, its outer dimensions can also be larger than those of the product membrane 1 and the protective membrane 2, in which case the product membrane 1 and the protective membrane 2 are adhered together through the gaps between the discrete shielding membranes 3. The masking film 3 uses single-sided adhesive tape, and its adhesive side is pasted to the adhesive side of the protective film 2. At this time, the corresponding positions between the protective film 2 and the product film 1 will not stick together.

[0026] Please see Figure 3 , Figure 4 and Figure 5 A die-cutting waste removal device for processing waste film from isolated islands includes a base plate 4. Several height adjustment components 5 are fixedly connected to the base plate 4. Multiple height adjustment components 5 are provided. A central shaft 6 is rotatably connected to each height adjustment component 5. Different rollers are provided on the outside of the central shaft 6, including at least a feeding roller, a winding roller, two waste removal rollers and two or more guide rollers. In addition, other types of rollers can be provided as needed. A die-cutting assembly 7 and a waste removal auxiliary assembly 8 are fixedly connected to the base plate 4. Guide rollers guide the product film 1 to the position of the die-cutting assembly 7. As the die-cutting assembly 7 moves up and down, the product film 1 is processed into individual products. Then, as the take-up rollers rewind, the product film 1 moves forward and between two waste removal rollers. The two waste removal rollers convey waste removal tape, causing the waste removal tape and the product film 1 to move forward synchronously. As the waste removal tape separates, isolated waste materials are adhered and separated by the tape. The waste removal auxiliary assembly 8 is located above the waste removal tape and moves up and down synchronously with the die-cutting assembly 7. The waste removal auxiliary assembly 8 rises and falls synchronously with the die-cutting assembly 7, squeezing the waste removal tape and isolated waste materials. After squeezing, the waste removal tape and isolated waste materials are more firmly adhered together, resulting in more thorough waste removal.

[0027] Please see Figure 6The height adjustment assembly 5 includes a fixed bracket 9, a first slider 10 slidably connected longitudinally to the fixed bracket 9, and an adjusting screw 11 rotatably connected to the fixed bracket 9. The first slider 10 is threadedly connected to the adjusting screw 11, and the central shaft 6 is rotatably connected to the first slider 10. Rotating the adjusting screw 11 causes the first slider 10 to move up and down, which in turn drives the central shaft 6 to move up and down, thus adjusting the height of different rollers mounted on the outside of the central shaft 6 to a suitable position. Alternatively, the adjusting screw 11 can be removed, and a locking bolt can be directly installed on the first slider 10. After sliding the first slider 10 to a suitable height, the height can be locked by rotating the locking bolt.

[0028] The die-cutting assembly 7 includes a telescopic drive component 12 fixed below the base plate 4. A second slider 13 is fixedly connected to the piston rod of the telescopic drive component 12. A connecting rod 14 for connecting the die-cutting tool is connected to the second slider 13. A guide seat 15 is fixedly connected to the base plate 4, and the second slider 13 is slidably connected to the guide seat 15. The die-cutting assembly 7 moves up and down via the telescopic drive component 12, which can be powered by an electric telescopic rod or a hydraulic telescopic rod. During the telescopic movement of the telescopic drive component 12, the second slider 13 moves up and down. Since the connecting rod 14 is connected to the second slider 13, it moves up and down synchronously with the second slider 13. The die-cutting tool is connected to the connecting rod 14, and the die-cutting process can be performed with the up and down movement. The die-cutting tool can slide along the axial direction of the connecting rod 14, thereby moving to the processing position for processing. To prevent relative sliding between the die-cutting tool and the connecting rod 14, a corresponding locking mechanism needs to be provided on the die-cutting tool.

[0029] Please see Figure 7A horizontal telescopic rod 16 is fixedly connected to the side of the second slider 13. A waste removal auxiliary component 8 is connected to the end of the horizontal telescopic rod 16. The waste removal auxiliary component 8 includes a pressure rod 17 fixedly connected to the end of the horizontal telescopic rod 16. A pressure block connecting sleeve 18 is slidably connected to the outside of the pressure rod 17. When the pressure block connecting sleeve 18 is pressed down, the pressure block at the bottom presses the waste removal tape against the isolated waste material. The horizontal telescopic rod 16 moves up and down synchronously with the die-cutting component 7, driving the pressure block connecting sleeve 18 to move up and down. The bottom of the pressure block connecting sleeve 18 is connected to a pressure block. The pressure from the pressure block ensures that the waste removal tape and the isolated waste material are tightly adhered, achieving complete waste removal. The pressure block is preferably made of elastic silicone or similar materials to ensure a tight fit. The waste removal auxiliary component 8 and the die-cutting component 7 can also achieve motion transmission through other linkage structures. For example, a transmission rod can be rotatably connected between the waste removal auxiliary component 8 and the die-cutting component 7, with both ends of the transmission rod connected to the waste removal auxiliary component 8 and the die-cutting component 7 respectively. This allows the waste removal auxiliary component 8 to synchronously perform waste removal assistance during the movement of the die-cutting component 7. The lateral telescopic rod 16 allows the waste removal auxiliary component 8 to be positioned along the waste removal direction, ensuring that when the waste removal auxiliary component 8 presses down, it precisely squeezes the isolated waste material and the waste removal tape for different processing gaps.

[0030] A transverse slide groove 19 is fixedly connected to the base plate 4, and a longitudinal slide groove 20 is slidably connected inside the transverse slide groove 19. The pressure rod 17 is slidably connected to the longitudinal slide groove 20. Through the structural arrangement of the transverse slide groove 19 and the longitudinal slide groove 20, the pressure rod 17 is further guided to ensure the smooth operation of the pressure rod 17.
