[0015] Compared with the prior art, the technical scheme of the present application has the following advantages: (1) The upper part of the pushing mechanism is provided with a pressing plate assembly, a connecting assembly, a rolling assembly and a cleaning assembly. Through the cooperation of the pushing mechanism and the pressing plate mechanism, efficient and accurate positioning and pressing of the wood composite board are realized. Two sets of fixed limiting rods arranged on the workbench and the U-shaped frame on the pressing plate assembly constitute a predetermined positioning effect. The operator only needs to preliminarily place the wood board between the two fixed limiting rods to complete the rough positioning. When the wood board is pushed towards the direction of the laser marking machine and enters the inside of the U-shaped frame, its three sides will be in close contact with the two side plates and a long horizontal plate of the U-shaped frame. This three-sided surrounding structure accurately constrains the wood board in the predetermined carving area, ensuring that the initial position of the wood board relative to the laser head is highly consistent every time it is carved, and fundamentally avoiding problems such as carving misplacement, incompleteness or exceeding the boundary caused by manual placement deviation, greatly improving the accuracy of the carved pattern and the consistency of the product. In terms of pressing, when the wood board reaches the specified position, the driving motor starts to drive the bidirectional ball screw to rotate, so that the two sliding blocks move in opposite directions. The sliding blocks press the whole pressing plate assembly downward through the rotating plate. During this process, the pressing plate itself acts as a large-area pressure distribution plate, which can uniformly apply pressure to the entire upper surface of the wood board, effectively preventing the wood board from producing slight displacement due to local stress or equipment vibration during carving. At the same time, the sliding cooperation of the limiting long rod and the fixed long rod ensures that the pressing plate can only move vertically up and down, avoiding any lateral deviation, further enhancing the stability of the pressing. This stable and reliable pressing mechanism creates an extremely stable working platform for the laser marking machine, so that the laser beam can always be accurately focused on the preset carving path, thereby carving out high-quality patterns with clear outlines and sharp details, which is significantly better than the traditional manual pressing or simple clamp fixing method; (2) Before processing, that is, before the wood board enters the carving station, the rolling assembly and the cleaning assembly in the connecting assembly clean the wood board, the external water supply device injects water into the water pipe through the connecting water pipe, and forms fine water mist through the atomizing spray hole, which is uniformly sprayed on the rolling brush below, so that the surface of the fiber cloth is wet. When the wood board moves forward, its surface first contacts the wet rolling brush, which rises and rotates under pressure. This action is like a "wet scrubbing" for the wood board, which can effectively soak and preliminarily remove the surface dust and light impurities. Then, the wood board passes below the cleaning brush, which tightly adheres to the board surface under the pressure of the second spring, and completely scrapes off the excess water and impurities adhered by water. This pretreatment process ensures that the surface of the wood board to be carved is clean and dust-free, avoids the carbonization of impurities under high temperature of laser and the permanent adhesion of impurities on the surface of the wood board or the influence on the absorption of laser energy, thereby laying a solid foundation for obtaining clean and uniform color carving effect. In the carving process, the air duct network is embedded in the pressure plate above the carving area and the pattern assembly, and connected with the external air extraction device, so that the smoke gas is sucked in time at the source. After the air extraction device is started, negative pressure is formed in the gap between the installation channel, the C-shaped rod and the connecting short rod, and the smoke gas generated by laser carving is almost sucked into the third air duct at the moment of birth, and then passes through the second air duct, the first air duct, and finally is discharged through the connecting air pipe. This way greatly reduces the diffusion of smoke gas, effectively prevents secondary pollution, ensures the clarity of the carving pattern and the cleanliness of the wood board surface, and the pushing assembly pushes the processed wood board out, so that it passes through the cleaning brush and the rolling brush again to finally clean the small amount of residual smoke dust and debris generated in the carving process.
