[0018] The present invention adopts the above technical solution to bring the following beneficial effects:

[0019] 1. The steel-wood laser cutting equipment, through the coordinated operation of the first guide rail, the first linear motor, the drive motor and the rotating rod, enables the grinding roller to rotate and grind the upper surface of the steel-wood plate, effectively improving the surface flatness of the steel-wood plate, while removing impurities on the surface of the steel-wood plate to avoid affecting the laser cutting effect, providing a better processing foundation for subsequent laser cutting, ensuring cutting accuracy and cutting surface quality, and cooperating with the side rod, the sliding rod and the adjustment frame to enable the grinding roller to contact the surface of the steel-wood plate of different thicknesses. When processing steel-wood plates of different thicknesses, there is no need to adjust the height of the grinding roller separately. By fixing the steel-wood plate, it can be ensured that the grinding roller is in good contact with the surface of the steel-wood plate, thereby improving the stability of the grinding process and ensuring the consistency of the grinding effect.

[0020] 2. This steel-wood laser cutting equipment, through the combined structure of the cam, the second telescopic rod and the knocking plate, knocks on the upper surface of the steel-wood plate when the grinding roller is working, so that the steel-wood plate vibrates. The vibration not only helps the steel-wood plate to contact the grinding roller more evenly and improve the grinding effect, but also makes it easier to fall off the impurities on the surface of the steel-wood plate, which is convenient for the exhaust fan to collect, reduces impurity residues, improves grinding efficiency, and saves grinding time and cost.

[0021] 3. This steel-wood laser cutting equipment uses a knocking mechanism composed of a wave plate, a moving rod, a swing rod and a swing block. When the first linear motor moves, it drives the knocking rod to repeatedly knock on the lower surface of the steel-wood plate, further vibrating the steel-wood plate. Combined with the knocking on the upper surface of the steel-wood plate, the steel-wood plate is vibrated as a whole, promoting full contact between the steel-wood plate and the grinding roller, improving the grinding effect, and helping impurities fall off, preparing for laser cutting.

[0022] 4. This steel-wood laser cutting equipment drives the air outlet duct to rotate when the grinding roller is raised or lowered through the first telescopic rod, so that the air outlet duct is always facing the contact point between the grinding roller and the steel-wood plate. The wind blown by the hair dryer can blow away the dust generated by grinding in time. At the same time, the exhaust fan sucks the dust into the collection box through the exhaust duct, avoiding dust from spreading in the working environment and affecting the health of operators. It can also prevent dust from falling on the surface of the steel-wood plate or the laser cutting parts, thereby affecting the subsequent laser cutting effect.

[0023] 5. In this steel-wood laser cutting equipment, the first telescopic rod drives the air outlet duct to rotate when the grinding roller is raised or lowered, so that the air outlet duct is always facing the contact point between the grinding roller and the steel-wood plate. The wind from the hair dryer can blow away the dust generated by grinding in time, and the exhaust fan sucks the dust into the collection box through the exhaust duct to prevent the dust from spreading in the working environment and affecting the health of operators. It can also prevent the dust from falling on the surface of the steel-wood plate or the laser cutting parts, thereby affecting the subsequent laser cutting effect. The heating plate heats the lower surface of the steel-wood plate to keep the wood inside the steel-wood plate dry. Excessive moisture in the wood inside the steel-wood plate will affect the laser cutting effect, such as causing a rough cutting surface and cracks. Removing moisture by heating can effectively avoid these problems, ensure the quality and accuracy of laser cutting, and improve the quality of the finished cut product.

The slider 35 descends to make the grinding roller 38 contact the upper surface of the steel-wood plate.

At the same time, when the first linear motor 32 moves, it will drive the moving rod 74 to move, thereby driving the wave plate 73 to move downward, and the wave plate 73 will squeeze the swing block 76 downward, thereby driving the most The swing arm 75 on the left side rotates slightly clockwise, so that the knocking rod 77 on the swing arm 75 knocks on the lower surface of the steel-wood plate, and the knocking rods 77 on the other swing arms 75 are driven to knock through the connecting block 78 and the linkage rod 79. The spring and the torsion spring can enable the first linear motor 32 to reciprocate and knock on the lower surface of the steel-wood plate when moving, so that the steel-wood plate is in contact with the grinding roller 38 more evenly, improving the grinding effect, and at the same time helping to make impurities fall off the surface of the steel-wood plate more easily.
