Description

Technical Field

[0001] The utility model relates to the technical field of woodworking engraving machines, in particular to a pressing device for woodworking engraving machines. Background Art

[0002] In terms of processing principle, engraving is a combination of drilling and milling, and woodworking engraving machines usually use mechanical engraving machines. In order to make the engraved patterns more accurate, it is usually necessary to fasten the wooden board to the work surface. Traditional fixing methods, such as fixing only at the edge of the wooden board, may cause deformation in the center of some thinner wooden boards, thus affecting the engraving effect and product quality. During the engraving process, the stability and accuracy of the wooden board are ensured, and the slight movement of the wooden board caused by vibration is prevented, thereby improving the quality of woodworking products. The background technology of the clamping device of the woodworking engraving machine involves the improvement and optimization of the wooden board fixing method to improve the engraving accuracy and product quality. With the advancement of science and technology and the development of the woodworking industry, more innovative clamping devices may appear in the future to meet the needs of different woodworking engravings.

[0003] Publication No. "CN217751843U" provides a clamping device for a woodworking engraving machine, including an operating table, a sliding frame is slidably arranged on the operating table, an engraving mechanism is slidably arranged on the sliding frame, an engraving head is arranged on the engraving mechanism, connecting plates are fixedly connected to the two side ends of the operating table, rectangular plates are fixedly installed on both sides of the bottom end of the operating table, and clamping structures are arranged on both sides of the operating table. The rotation of two gears will drive two rotating rods to rotate, and the rotation of the two rotating rods will drive the rectangular block and the pressure roller to rotate. The deflection angle of the pressure roller can be adjusted so that the surface of the pressure roller is tightly fitted to the surface of the workpiece, and workpieces of various thicknesses can be clamped, which is convenient for engraving the workpiece, avoiding the position displacement of the workpiece during the processing, ensuring the processing accuracy of the workpiece, and improving the processing quality.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] When the above device is working, although the clamping structure can be used to clamp workpieces of various thicknesses, the workpiece often needs to be moved during the engraving process. When moving, the pressure roller needs to be moved away, and then the position needs to be adjusted and clamped again, which is time-consuming and labor-intensive and inconvenient to operate.
