Description

Technical Field

[0001] The utility model relates to the technical field of wood processing equipment, in particular to a pressing device for a sand planer. Background Art

[0002] A sander, a type of sanding machine, is commonly used in wood processing. It primarily uses a rotating planer head to cut and polish the wood surface. Sanding and polishing are synonyms, both referring to the physical removal of unevenness, uneven thickness, and non-conforming materials and objects through abrasive cloth, grinding wheels, sandpaper, scouring pads, non-woven polishing wheels, and other methods to achieve a smoother, more uniform, and consistent finish, ultimately meeting the process standards. Currently, a sander requires a pressure roller to press the wood board tightly, ensuring it can be sanded steadily while being transported.

[0003] However, the height of the pressure roller cannot be adjusted. When the thickness of the wooden boards is different, the thinner wooden boards are not easy to be pressed, which affects the efficiency and quality of sanding. Moreover, when the pressure roller is used for a long time, the surface will be worn, which affects its pressing effect on the wooden boards. The existing sanding machine is not convenient to replace the pressure roller; therefore, it does not meet the existing needs. We have proposed a pressing device for a sanding machine.
