[0002] Anti-splashing pad is also called anti-splashing board and splash guard pad. It is a protective device used to prevent liquid from splashing out. It is widely used in various places where liquid splashing is needed to be prevented. In terms of material, materials with flame-retardant properties are usually chosen to reduce the risk of fire. According to the specific application scenario and usage requirements, anti-splashing pads can be designed in different shapes and sizes to meet various needs, including effectively preventing liquid from splashing out, keeping the work area clean and dry, and being designed with a drainage function to automatically drain the splashed liquid, saving time and being convenient. With the rapid development of automobiles, automotive interior has an irreplaceable effect on the service life of the automobile. The anti-splashing pad for the automobile is a protective pad that prevents the front of the automobile from being contaminated by mud brought in by people. It can ensure the cleanliness of the interior of the automobile. The anti-splashing pad trepanning device is mainly used to accurately punch a certain number and size of holes in the anti-splashing pad material. These holes are usually used to allow liquid to pass through or prevent liquid from splashing out while maintaining the overall structure and function of the anti-splashing pad.

[0003] To this end, China Patent No. CN209831921U discloses a dust-free plate trepanning device, which includes a workbench, support frames on both sides of the workbench, a support beam mounted on the support frames, a cutting head capable of rotating and vertically lifting for combined motion, a dust removal unit capable of moving synchronously with the cutting head, the dust removal unit being positioned higher than the tail end of the cutting head, the dust removal unit including a dust suction hole, a dust collection chamber, a fan box, a suction fan, and a wind pipe, the dust suction hole being aligned with the cutting head, the dust suction hole being in communication with the dust collection chamber, the suction fan being installed in the fan box, and the suction fan being connected to the dust collection chamber through the wind pipe. The dust-free plate trepanning device has the advantages that the dust suction hole is very close to the cutting operation position, wood chips and dust can be basically sucked and removed, and the dust removal effect is good. Moreover, it does not need to increase the power of the suction fan, which saves energy and reduces costs.
