Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting tools for rubber production, and more specifically, to a cutting tool for removing metal impurities from rubber sheets. Background Technology
[0002] As is well known, when a rubber sheet passes through an X-ray metal detector, if there are metal impurities inside, the detector will locate the metal and, during the cutting process, a vertical cutting blade will descend to cut off the metal portion of the rubber sheet. Currently, the main cutting tools used in this field are cylindrical blades, which have a large contact area with the rubber sheet, resulting in greater resistance during cutting. This leads to a short lifespan for components such as the cylinder and blade head of the cutting equipment, making rubber cutting time-consuming, labor-intensive, and inefficient. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a rubber sheet metal impurity removal tool, which solves the defects of short service life of cylinders, cutters and other components of single-sided cutting equipment, and time-consuming, labor-intensive and inefficient rubber sheet cutting.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a rubber sheet metal impurity removal tool, which is provided with a blade body. The blade body is cylindrical in shape, and a mounting flange is machined at the rear end of the blade body. The front end of the blade body is machined with a cutting edge at a 20-degree angle at even intervals around the inner wall of the cylindrical shape. A central through hole is machined in the axial direction of the blade body, and a cylindrical rod is inserted into the central through hole.
[0005] The advantages of this invention are high precision, high efficiency in cutting rubber sheets, and long service life. Attached Figure Description
[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0009] In the diagram: 1. Cutting edge, 2. Mounting flange, 3. Center through hole, 4. Tool body. Detailed Implementation
[0010] In the figure, the present invention is provided with a blade body 4, which is a cylindrical structure. The rear end of the blade body 4 is machined with a mounting flange 2. The front end of the blade body 4 is machined with cutting edges at 20-degree angles evenly spaced around the inner wall of the cylindrical shape. The blade body 4 is machined with a central through hole 3 in the axial direction, and a cylindrical rod is inserted into the central through hole 3.
[0011] This utility model is formed by one-time processing of an alloy cylinder. When the X-ray inspection equipment detects metal impurities and needs to cut the rubber sheet, the cutting edge 1 directly pushes into the rubber sheet and cuts the rubber sheet off in one go. When the cutting blade retracts, the cylindrical rod at the rear of the cutting blade pushes out the cut rubber sheet through the central through hole 3 of the cutting head.
