Description

Technical Field

[0001] The utility model relates to the technical field of wooden door production, in particular to a sanding machine for wooden door production. Background Art

[0002] Wooden doors, that is, wooden doors, can be divided into many types according to material, craftsmanship and purpose. They are widely used in civil, commercial buildings and residences. When wooden doors are produced, sanders are needed to polish them.

[0003] For example, a sanding machine for wooden door production with the authorization announcement number CN213561618U includes a sanding table, a support frame, a positioning assembly and a sanding mechanism. The support frame is fixedly connected to the center of the upper end of the sanding table. Although the above document can ensure that the polishing depth of each part of the wooden door surface is consistent and improves the flatness of the wooden door surface polishing; however, when in use, the sanding machine puts the wooden door on a conveyor roller to move the wooden door and polish it. Since the wooden door is not polished during polishing, No fixation is performed to prevent the position of the wooden door from shifting when the wooden door is moved, which causes the position of the wooden door to shift as well, thereby reducing the effect of the sanding machine on the wooden door. At the same time, when the sanding machine is sanding the wooden door, it sands the wooden door with a sanding disc. Since the position of the sanding disc is fixed and cannot be moved, only one position of the wooden door can be sanded at a time. The staff is required to move the wooden door and sand other positions, which is troublesome, thereby reducing the efficiency of the sanding machine on the wooden door. Utility Model Content
