Description

Technical Field

[0001] The utility model relates to the technical field of diffusion plate processing, in particular to the technical field of a diffusion plate cutting device. Background Art

[0002] Diffuser plates are widely used in fields such as liquid crystal displays and LED lighting. Their main function is to fully scatter the incident light to achieve a softer and more uniform illumination effect. The finished diffuser plates need to be cut and then polished to obtain diffusers of corresponding sizes and with a smooth surface.

[0003] Currently, the diffusion plate needs to maintain material stability during the cutting process. However, during the conveying process of the diffusion plate by the existing device, the position of the plate may sometimes deviate, resulting in cutting deviation.

[0004] In order to solve the problems raised in the background technology, for example, application number CN201822058648.0 discloses a diffusion plate cutting machine, including a cutting machine body, wherein passive rollers are respectively provided on both sides of the cutting machine body, the passive rollers are sleeved on the second shaft, and the two ends of the second shaft are respectively slidably connected to a stand, which is provided on the frame, and the passive rollers are equidistantly distributed on the shaft, the outer wall of the shaft is connected to one end of the movable column, the movable column and the passive roller are staggered, and the other end of the movable column is inserted in the cylinder, and one end of the movable column inserted in the cylinder is connected to a compression spring. The diffusion plate cutting machine adopts the support of the passive cylinder, the movable column and the compression spring, so that the passive roller can always keep the pressure on the diffusion plate, thereby effectively preventing the deviation of the plate position. However, the device still has the following defects:

[0005] Although this device can always maintain a tight pressure effect on the diffuser plate, the diffuser plate will generate very high temperature during the cutting process. If it is not cooled down in time, the service life of the cutting machine will be greatly reduced. At the same time, it is easy to cause the cut side of the diffuser plate to turn black, greatly reducing the appearance of the diffuser plate.

[0006] To solve the problems raised in the above-mentioned technology, for example, application number CN202021186939.9 discloses a diffusion plate cutting device, comprising a lower support rod, the upper end of the lower support rod is fixedly connected to the lower mounting plate, the lower mounting plate is provided with a first mounting groove inside, the first mounting groove is rotated to connect the first screw rod inside, the surface of the first screw rod is installed with a first moving block, the upper end of the lower mounting plate is fixedly connected to the upper support rod, through the mutual cooperation of the circulation pipe, the water supply nozzle, the connecting pipe, the water pump and the water tank, the cutting part can be cooled during the cutting process of the cutting machine, thereby avoiding the blackening of the cutting part of the diffusion plate due to excessive cutting temperature, which not only ensures the aesthetics of the diffusion plate after cutting, but also ensures the service life of the cutting machine. However, the device still has the following defects:

[0007] Although the device can cool the cutting area during the cutting process of the cutting machine, the material of the diffusion plate is relatively soft due to hot pressing right after production. Therefore, it is necessary to adjust the tension component to stretch the diffusion plate during the cutting process to maintain the tension effect and prevent wrinkles from occurring. However, the device lacks a tension adjustment component, which results in the diffusion plate being unable to achieve the tensioning purpose during the cutting process, thereby affecting the cutting accuracy. Summary of the Invention
