[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] The utility model provides a plastic film processing and cutting device, comprising a film 5 conveying roller frame 1, a guide roller frame 2 is installed on the right side of the film 5 conveying roller frame 1, a rotatable roller shaft 201 is installed on the film 5 conveying roller frame 1 and the guide roller frame 2, a cutting mechanism 3 is installed between the film 5 conveying roller frame 1 and the guide roller frame 2, the cutting mechanism 3 comprises a base 301, a rising cylinder 302 is fixedly connected to the base 301, a sliding rod 303 is slidably connected to the rising cylinder 302, a carrier 304 is fixedly connected to the sliding rod 303, and the carrier A fixing plate 4 is fixedly connected above 304, and the fixing plate 4 is connected to the base 301 through a guide column 401, providing structural support for the cutting structure as a whole. A film 5 is arranged on the carrier 304, and a downward pressure cylinder 402 is fixedly connected to the fixing plate 4, and a pressure rod 403 is movably connected in the downward pressure cylinder 402, and a tool holder 404 is fixedly connected to the pressure rod 403, and a cutter 405 is fixedly connected to the tool holder 404 through a fastener. The film 5 is located between the cutter 405 and the carrier 304, providing structural support for the later cutting of the film 5.

[0020] When the plastic film processing and cutting device is actually used, the cutting mechanism 3 is located between the film 5 conveying roller frame 1 and the guide roller frame 2. When the film 5 needs to be cut, the film 5 conveying roller frame 1 stops conveying, and the rising cylinder 302 drives the sliding rod 303 to drive the carrier 304 to move upward until the carrier 304 abuts against the film 5, and then the pressing cylinder 402 drives the pressing rod 403 to drive the cutter 405 on the knife frame 404 to move toward the carrier 304 until the cutter 405 cuts into the groove 305 in the carrier 304. After the film 5 above the carrier 304 is cut, the pressing cylinder 402 drives the cutter 405 to reset upward, and then the rising cylinder 302 drives the carrier 304 to reset downward, and the cutting work of the film 5 is completed. By installing a cutting mechanism 3 between the film 5 conveying roller frame 1 and the guide roller frame 2, the upward cylinder cooperates with the carrier 304 to move upward until it stops after abutting against the film 5, and then the downward cylinder 402 drives the cutter 405 downward until the cutter 405 enters the groove 305 in the carrier 304 to complete the cutting of the film 5, and then the downward cylinder 402 and the upward cylinder drive the corresponding components to reset. Compared with the conventional manual cutting method by the staff, the technical solution adopted by the utility model can orderly cut the film 5 between the film 5 conveying roller frame 1 and the guide roller frame 2, thereby realizing the semi-automatic production and processing of the film 5 cutting work, and the overall structure is compact, easy for the staff to install and maintain, and the structural space layout is reasonable.

[0021] like Figure 1-3 As shown, a groove 305 is installed on the carrier 304, the width of the groove 305 is greater than the thickness of the cutter 405, the width of the film 5 is smaller than the width of the carrier 304, and the working conveying rhythm between the film 5 conveying roller frame 1 and the guide roller frame 2 is adapted to the cutting mechanism 3.

[0022] The effect achieved by the entire embodiment 1 is that, during use, the width of the film 5 is smaller than the width of the carrier 304, which is beneficial for the staff to control the cutter 405 used for cutting, ensuring that the cutter 405 can enter the groove 305 in the carrier 304 in an orderly manner, and the working conveying rhythm between the film 5 conveying roller frame 1 and the guide roller frame 2 is adapted to the cutting mechanism 3, so that the cutter 405 enters the carrier 304 in an orderly manner.

[0023] Working principle: The cutting mechanism is located between the film conveying roller frame and the guide roller frame. When the film needs to be cut, the film conveying roller frame stops conveying, and the rising cylinder drives the sliding rod to drive the carrier to move upward until the carrier contacts the film, and then the pressing cylinder drives the pressing rod to drive the cutter on the knife frame to move toward the carrier until the cutter cuts into the groove in the carrier. After the film above the carrier is cut, the pressing cylinder drives the cutter to reset upward, and then the rising cylinder drives the carrier to reset downward, thereby completing the film cutting work.
