Description

Technical Field

[0001] The utility model relates to the technical field of polarizer processing, in particular to a cutting machine used for polarizer processing. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizers in front and behind, which are close to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. It is responsible for converting the scattered light emitted by the light source into polarized light, and combined with the twisting characteristics of liquid crystal molecules, it controls whether the light passes through, thereby affecting the transmittance and viewing angle range, forming light and dark contrast, and producing display images. Polarizers are usually composed of multiple layers of materials, including PVA (polyvinyl alcohol) film, TAC (triacetyl cellulose) film, protective film, release film and pressure-sensitive adhesive, etc. Among them, the PVA film is responsible for polarization, while the TAC film provides protection and water resistance. According to the publication number CN215969167U, a polarizer cutting technology field is disclosed, especially a slicer for polarizer cutting, including a base plate, an inverted T-shaped rod is inserted into the through hole of the horizontal part of the first bracket on the base plate, a first cross-shaped knife groove is provided in the middle of the support block of the vertical part of the inverted T-shaped rod, a cutting knife group is provided in the cross-shaped slot on the horizontal part of the first bracket, and an extrusion plate and a wear-resistant extrusion block are provided in the middle of the horizontal part of the second bracket through an electric telescopic rod. In the utility model, the polarizer cutting slicer has a compact structure, a small volume, and a simple structure, which saves time and effort in later maintenance. At the same time, by arranging a spring on the inverted T-shaped rod, when the spring is in a natural state, the top surface of the cutting group is located within the first cross-shaped knife groove of the support block, and when the spring is in a compressed state, the top surface of the cutting group extends out of the first cross-shaped knife groove of the support block to avoid the cutting group from being exposed, thereby greatly improving the safety of the operator at work. However, when in use, some polarized materials are small and are not conducive to cutting by large cutting machines, which wastes resources excessively. In addition, when the cutting machine is cutting, it is impossible to quickly position and cut, which affects efficiency. In addition, when cutting one side, the material needs to be taken out again for position adjustment before repositioning and cutting. This process is time-consuming and affects efficiency. Therefore, it is urgent to design a cutting machine for polarizer processing to solve the above problems. Utility Model Content
