Description

Technical Field

[0001] The utility model relates to the technical field of film processing, in particular to a waste edge cutting device for films. Background Technique

[0002] In the technical field of film processing such as battery diaphragms, during film production, due to clamping or process reasons at both ends of the film, the quality of the film at this position does not meet the requirements, and the unqualified parts at the end faces need to be cut off. The traditional cutting method generally uses a cylinder to drive the tool rest to rotate to achieve the contact between the blade and the film, and cut off the waste edge of the film. The traditional cutting structure requires a large installation space, and generally only one blade can be assembled on the tool rest of this structure. After the blade is worn, it needs to be stopped for replacement, which affects the processing efficiency of the film.

[0003] Therefore, we designed a new type of waste edge cutting device. Through the horizontal ejection of the cylinder, the working position state of the contact between the blade and the film and the non-working position state of the cylinder retraction are realized, and the tool rest adopts a ratchet structure to realize the free switching between the main cutting blade and the spare blade, reducing the downtime due to tool change and improving the production efficiency of the film.

Detailed Embodiments

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0020] Please refer toFigures 1 - 4 , this embodiment provides a waste edge cutting device for a thin film, including a bottom plate 1. A connecting plate 3 is slidably arranged on the bottom plate 1. Specifically, as a conventional design, a slide rail is designed on the bottom plate 1, and corresponding sliders are arranged at the bottom of the connecting plate 3, so as to realize the sliding connection between the connecting plate 3 and the bottom plate 1. At the same time, as a conventional setting, in order to drive the movement of the connecting plate 3, a cylinder 2 is fixedly arranged on the bottom plate 1, and the output end of the cylinder 2 is connected to the connecting plate 3.

[0021] A tool rest seat 4 is arranged at one end of the connecting plate 2. A rotary tool rest plate 5 is arranged on one side of the tool rest seat 4. A plurality of corresponding cutting knives 6 are symmetrically arranged on the rotary tool rest plate 5. Preferably, two cutting knives 6 are correspondingly arranged on the rotary tool rest plate 5. In order to realize the installation of the cutting knife 6, preferably, as Figure 2 shown, two knife mounting grooves 14 are symmetrically formed on the rotary tool rest plate 5. One end of the cutting knife 6 is fixedly arranged in the knife mounting groove 14 through a knife removal bolt 13.

[0022] In order to enable the rotary tool rest plate 5 to rotate to replace the cutting knife 6 for cutting the thin film 12, as Figures 2 - 3 shown, a ratchet wheel 9 is rotatably arranged in the tool rest seat 4. A limit retaining tooth plate 10 that is engaged with the ratchet wheel 9 is correspondingly arranged at the lower end of the ratchet wheel 9. As Figure 2 shown, as a conventional operation for those skilled in the art, the teeth on the ratchet wheel 9 should correspond to the cutting knife 6. In this application, preferably, two teeth are correspondingly arranged on the ratchet wheel 9. At the same time, one end of the limit retaining tooth plate 10 is rotatably connected to the tool rest seat 4. The lower side of the other end of the limit retaining tooth plate 10 is connected to a spring 11, and the lower end of the spring 11 is fixedly connected to the tool rest seat 4. A tool changing shaft 8 is rotatably arranged in the tool rest seat 4. One end of the tool changing shaft 8 is fixedly connected to the ratchet wheel 9, and the other end of the tool changing shaft 8 passes through the tool rest seat 4 and is fixedly connected to the rotary tool rest plate 5. In order to facilitate the rotation of the rotary tool rest plate 5, the tool changing shaft 8 passes through the rotary tool rest plate 5 and is connected with a tool changing knob 7. By rotating the tool changing knob 7, the positions of the two cutting knives 6 can be replaced.

[0023] In actual application, as Figure 4 shown, the direction indicated by the arrow is the traveling direction of the thin film 12. The front side of the cutting knife 6 should be in contact with the thin film 12. As the thin film 12 moves, the edge of the thin film 12 is cut off. It should be noted that the limit retaining tooth plate 10 should limit the ratchet wheel 9 to rotate only clockwise to prevent the cutting knife 6 from rotating as the thin film 12 moves, that is, the rotation direction of the ratchet wheel 9 is opposite to the traveling direction of the thin film 12. The design of the tooth directions of the corresponding ratchet wheel 9 and the limit retaining tooth plate 10 should be a conventional design familiar to those skilled in the art, and will not be elaborated in this application. When it is necessary to replace the positions of the two cutting knives 6, as Figure 3As shown, turn the tool change knob 7 clockwise to drive the ratchet 9 to rotate clockwise. The ratchet 9 presses down the limit stop gear plate 10, and the spring 11 is compressed. When the teeth on the upper side of the ratchet 9 move to the corresponding position on the lower side, the spring 11 pushes the front side of the limit stop gear plate 10 to rise, and the limit stop gear plate 10 catches the teeth on the lower side of the ratchet 9 to prevent the ratchet 9 from rotating counterclockwise. When the film 12 moves downward, the output end of the cylinder 2 pushes forward, so that the front cutter 6 contacts the film 12, and the cutter 6 for the front operation can stably cut the film 12.

[0024] It should be noted that the above embodiments only describe the technical solutions and technical features of the present application specifically and clearly. For those skilled in the art, the solutions or features that belong to the prior art or common general knowledge are not described in detail in the above embodiments.

[0025] In addition, the technical solutions of the present application are not limited to the above embodiments. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
