Description

Technical Field

[0001] This utility model relates to the technical field of film processing equipment, specifically to an adjustable cutting roller. Background Technology

[0002] A roll of substrate is coated with a specific functional adhesive, paint, or ink by a coating machine, dried, and then cut into sheets or rolled up. The substrate is rolled up by a winding device, and cut into sheets by a cutting roller. In the prior art, the position of the cutter on the cutting roller used for substrate cutting is fixed. By changing the model of the carrier roller, the rotation speed of the cutter set on the outer surface of the carrier roller is changed, and the frequency of the rotating cutter when it reaches the cutting position is controlled and adjusted to obtain material sheets of different specifications. In the prior art, the cutting roller is replaced to meet different cutting requirements of the film. However, using the cutting roller in the prior art to cut the film has the technical problem of high replacement cost. To address the aforementioned issues, patent application CN202322946378.8 discloses an easily adjustable cutting roller. It includes a roller, several cutting blades, a first rotating device, and a second rotating device. The roller surface is provided with several mounting grooves extending through both ends of the roller, each groove being parallel to the central axis of the roller. Each cutting blade is slidably mounted in its respective mounting groove. The top plane of each cutting blade is curved, and the length of each cutting blade is the same as the length of the roller. Cutting protrusions are provided on the top plane of each cutting blade. The first rotating device and the second rotating device are respectively mounted at both ends of the roller. This structural design effectively reduces the replacement cost of the cutting roller.

[0003] However, the above-mentioned cutting rollers still have the following problems: 1. The length of the cutting blades of the existing cutting rollers is mostly fixed, which cannot be quickly adjusted according to the length of the roll material, and it is not possible to process multiple roll materials simultaneously within the length range of the cutting roller, resulting in low applicability; when one part of the cutting blade wears out, the entire cutting blade needs to be replaced, and it cannot be replaced individually, resulting in high maintenance costs; 2. The cutting blades of the existing cutting rollers are connected by mounting slots and fixed by limiting strips. After long-term use, they will shift, affecting the subsequent cutting quality and efficiency, and the convenience of replacing the cutting blades is poor. Utility Model Content
