Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, specifically to a die-cutting waste removal device for a tape die-cutting machine. Background Technology

[0002] Due to its good adhesion and excellent waterproof performance, double-sided tape is widely used in electrical insulation, high-temperature shielding, waterproof sealing, shock absorption and cushioning, electronic shielding and other applications. As the applications become more diverse, its shapes also become more diverse. After the double-sided tape is die-cut, the waste material needs to be removed to obtain double-sided tape in various shapes.

[0003] In the production and processing of double-sided tape, die-cutting machines are usually used to perform die-cutting operations. Die-cutting is the process of forming specific parts from raw materials according to a predetermined shape through precision processing and cutting. Die-cutting is achieved through processes such as lamination, die-cutting, waste removal, and slicing. Among these processes, waste removal is very important.

[0004] In the prior art, there is a Chinese patent with authorization announcement number CN215395344U entitled "A Waste Removal Device for Buffer Tape Die Cutting on a Die Cutting Machine". The patent discloses a waste removal device for buffer tape die cutting on a die cutting machine, including a support plate and a scraping waste removal unit. Two front-to-back corresponding winding shaft brackets are fixed on the left side of the support plate surface, and a winding roller is rotatably connected between the two winding shaft brackets. A through groove is opened in the middle of the support plate. The scraping waste removal unit includes a knife holder, a rotating shaft, a knife seat, a scraper blade and a control component. The middle of the knife holder is connected to the rotating shaft, and the two ends of the rotating shaft are rotatably connected to the front and rear sides of the middle of the through groove.

[0028] 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.

[0029] Please see Figures 1-8 This utility model provides a technical solution: a die-cutting waste removal device for a tape die-cutting machine, including a base 1 and a first bracket 2 and a second bracket 3 installed on the base 1. A tape body 4 is wound between the first bracket 2 and the second bracket 3. A positioning frame 5 is provided on the base 1. A collection plate 6 is installed on the positioning frame 5. A collection groove 7 is opened inside the collection plate 6. An inclined scraper 13 is provided on the collection plate 6. A cleaning component 8 is provided inside the collection plate 6.

[0030] Specifically, the waste removal device for the tape die-cutting machine includes a base 1 and a first bracket 2 and a second bracket 3 mounted on the base 1. A non-slip pad is provided on the base 1 to improve the stability and performance of the waste removal device. The method by which the first bracket 2 and the second bracket 3 collect the tape is existing technology, such as the use of collecting rollers on the first bracket 2 and the second bracket 3; their structure and working principle will not be elaborated here. The tape body 4 is wound between the first bracket 2 and the second bracket 3 to meet operational needs. A positioning frame 5 is provided on the base 1, and a collecting plate 6 is mounted on the positioning frame 5 for collecting waste tape. A collecting groove 7 is formed inside the collecting plate 6, and an inclined scraper 13 is provided on the collecting plate 6, with the scraper 13 contacting the tape body 4. A cleaning component 8 is provided inside the collecting plate 6 to facilitate the cleaning of waste tape inside the collecting groove 7. Therefore, during use, the tape body 4 is installed between the first bracket 2 and the second bracket 3. At this time, the scraper 13 on the collection plate 6 will abut against the tape body 4. As the tape body 4 is wound up, the scraper 13 will discharge the excess waste tape. The excess waste tape will enter the collection tank 7 through the scraper 13. Then, the waste tape inside the collection tank 7 is cleaned regularly by the cleaning component 8. This can greatly improve the working efficiency of the waste discharge device. The waste discharge operation can be carried out without frequently replacing the scraper 13, which meets the work requirements.

[0031] In the embodiments provided by this utility model, the cleaning component 8 includes cleaning blocks 81 slidably connected to both sides inside the collection tank 7.

A servo motor 83 is installed on the collection plate 6, and the drive shaft of the servo motor 83 is coaxially connected to the bidirectional lead screw 82. When it is necessary to clean the waste glue inside the collection tank 7, the servo motor 83 rotates, thereby driving the bidirectional lead screw 82 to rotate, which in turn drives the cleaning blocks 81 to slide towards each other inside the collection tank 7, thus cleaning the inside of the collection tank 7 and improving the cleaning efficiency of the waste glue inside the collection tank 7, resulting in better performance. The lead screw is threadedly connected to the cleaning blocks 81 through threaded holes. Even if there is waste glue stuck in the threaded holes and on the lead screw, it does not affect the rotation of the lead screw and the sliding of the cleaning blocks 81 through the threaded holes. During the sliding stroke of the cleaning blocks 81, the waste glue inside the threads of the lead screw and the threaded holes can be discharged without affecting the normal sliding of the cleaning blocks 81.

[0032] In the embodiment provided by this utility model, the scraper 13 includes a protrusion 131 and a liquid guiding part 132 installed on the collection plate 6.
