Description

Technical Field

[0001] The utility model relates to the technical field of polaroid processing, in particular to an edge grinding machine for polaroid production. Background Art

[0002] Polarizer, also known as polarizing film, is an optical functional material mainly used to control the polarization direction of a specific light beam. The main function of a polarizer is to convert natural light without polarization into polarized light, thereby improving the display effect of liquid crystal displays. In an LCD display module, two polarizers are usually required. The lower polarizer converts the light beam emitted by the backlight into polarized light, and the upper polarizer analyzes the polarized light after being electrically modulated by the liquid crystal to form a light and dark contrast and realize image display. During the production process of polarizers, due to the problem of flying burrs on the edges of the material, the edges of the polarizers need to be polished by an edge grinding machine to prevent these burrs from affecting subsequent processing and product use.

[0003] In the process of grinding the polarizer with the grinding wheel on the edge grinding machine, dust is easily adhered to the surface of the grinding wheel. The dust adhered to the surface of the grinding wheel will affect the grinding accuracy and surface finish, resulting in uneven edges of the polarizer. In addition, if the grinding wheel works for too long, its surface will become hot, which may cause thermal damage to the polarizer material and cause deformation or damage to the edge of the polarizer.

[0004] In order to solve the above problems, this application proposes an edge grinding machine for producing polarizers. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes an edge grinding machine for producing polarizers.

[0006] The utility model provides an edge grinding machine for producing polarizers, comprising an edge grinding machine body and a grinding wheel mounted on the edge grinding machine body, wherein a semicircular cover shell covering the grinding wheel is mounted on the edge grinding machine body;

[0007] A fan assembly connected to the axis of the grinding wheel is installed at the front end of the semicircular cover, and the fan assembly rotates with the rotation of the grinding wheel. A multi-point air guide member connected to the fan assembly is installed on one side of the semicircular cover, and the multi-point air guide member is used to guide the wind generated by the fan assembly when it is running into the semicircular cover;

[0008] A dust extractor is installed on the other side of the semicircular cover, and the dust extractor is used to absorb dust in the semicircular cover.

[0009] Preferably, the fan assembly includes a wind tube, an air hole and a fan piece. The wind tube is installed at the front end of the semicircular cover. The wind tube is provided with an air hole on the outer periphery near one end of the semicircular cover. A fan piece is rotatably installed in the wind tube, and the end of the fan piece is connected to the axis of the grinding wheel.

[0010] Preferably, the fan component includes a rotating rod and fan blades. The rotating rod is horizontally arranged in the wind tube, and one end of the rotating rod rotates through one end of the wind tube and the side of the semicircular cover and is connected to the axis of the grinding wheel. The rotating rod is equipped with fan blades located in the wind tube.

[0011] Preferably, the multi-point air guide member includes a multi-point air guide portion and a second air guide pipe. The multi-point air guide portion is installed on one side of the semicircular cover shell and connected to its interior. The multi-point air guide portion is connected to the wind tube through the second air guide pipe.

[0012] Preferably, the multi-point air guide portion includes a first air guide pipe and several blowing pipes, and the several blowing pipes are installed on one side of the semicircular cover and connected to the interior of the semicircular cover. The first air guide pipe is connected to one end of the blowing pipe, and the bottom of the first air guide pipe is a sealing structure. The two ends of the second air guide pipe are respectively connected to the top of the first air guide pipe and the end of the wind tube away from the semicircular cover.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] By means of the fan assembly, multi-point air guide and dust extraction parts, the polarizer can be placed on the edge grinding machine body, and then the edge grinding machine body drives the grinding wheel to rotate to grind the polarizer. When the grinding wheel rotates, the fan assembly can be driven to rotate as well. When the fan assembly rotates, external cold air can be sucked into it, and then the cold air can be blown into the semicircular cover from multiple positions along the multi-point air guide parts, which can blow away the dust on the surface of the grinding wheel. When the cold air blows onto the grinding wheel, it can also cool the grinding wheel, and the dust blown off the grinding wheel can be absorbed by the dust extraction part. This structure uses the kinetic energy of the grinding wheel itself to drive the fan assembly to rotate, which can blow dust and cool the surface of the grinding wheel, which can effectively prevent thermal damage to the polarizer during processing and ensure the quality of polarizer processing.
