Description

Technical Field

[0001] The present invention relates to the technical field of fiberglass cutting, and specifically relates to a fiberglass cutting machine applicable to multi-angle operations. Background Art

[0002] Fiberglass, scientifically known as fiber-reinforced plastic, commonly known as FRP, that is, fiber-reinforced composite plastic. It is divided into glass fiber-reinforced composite plastic, carbon fiber-reinforced composite plastic, boron fiber-reinforced composite plastic, etc. according to the fibers used. It is a composite material with glass fibers and their products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material. Fiber-reinforced composite materials are composed of reinforcing fibers and a matrix. When fiberglass is produced, it needs to be cut according to requirements, and a fiberglass cutting machine is necessarily required.

[0003] However, when the existing fiberglass cutting machine applicable to multi-angle operations is in use, there are still certain problems:

[0004] Existing, such as a cutting machine for fiberglass products with the Chinese patent publication number CN218365013U, includes a workbench. A column is fixedly installed on the top plate of the workbench. A linear module is embedded and installed on the column. The sliding end of the linear module is fixedly connected with a fixing plate. Fixing blocks are fixedly installed at both ends of the front surface of the fixing plate. A rotating shaft is rotatably installed between the two fixing blocks. A cutting assembly is fixedly installed on the rotating shaft, and two connecting blocks are symmetrically and fixedly installed on the outer wall of the rotating shaft;

[0005] 1. When the existing fiberglass cutting machine is in use, it can only move linearly, which necessarily limits its difficulty in applying different-angle cutting operations during fiberglass processing. Although the angle of the fiberglass can be adjusted to change the cutting angle, if the fiberglass is long, effective prevention and positioning cannot be achieved;

[0006] 2. The existing cutting machine can only simply cut fiberglass, but there will necessarily be many burrs on the fiberglass after cutting, resulting in a large amount of subsequent processing work, increasing production costs. At the same time, there is also an inevitable risk of injury during manual handling or transfer;

[0007] 3. When the existing fiberglass cutting machine cuts fiberglass, it necessarily needs to set up lifting and linear motion structures, which also necessarily requires more costs, and the design of multiple electronic structures also increases the working failure rate of the cutting machine.

[0008] In view of the above problems, an innovative design is carried out on the basis of the original fiberglass cutting machine applicable to multi-angle operations. Summary of the Invention

[0009] The object of the present invention is to provide a fiberglass cutting machine applicable to multi-angle operations, so as to solve the problems presented in the above-mentioned background technology that the existing fiberglass is difficult to be used for cutting at different angles, and because the cutting burrs cannot be polished synchronously during cutting, it increases the subsequent processing cost and there is a risk of worker injury.
