Description

Technical Field

[0001] The utility model belongs to the technical field of wood floor production, in particular to a wood floor polishing device. Background Art

[0002] Wooden floor refers to floor made of wood. Wooden floor produced in China is mainly divided into six categories: solid wood floor, laminate floor, solid wood composite floor, multi-layer composite floor, bamboo floor and cork floor, as well as the emerging wood-plastic floor. High-strength wooden floor is mostly made of one or more layers of special paper impregnated with thermosetting amino resin, which is laid on the surface of artificial board substrates such as particleboard and high-density fiber. During the production and cutting process of wooden floor, burrs are easily generated on the surface of wooden floor, and generally it needs to be polished and polished by a polishing device.

[0003] The utility model patent with patent application publication number 202321614832.3 belongs to the technical field of wood floor processing equipment, and is particularly a grinding device for wood floor production, including a processing table, on which a conveying roller is provided, and a conveying wheel is provided on the conveying roller. The utility model can prevent the wood floor from deflecting by providing a conveying wheel and a positioning wheel on the conveying roller, and arranging the positioning wheel into three parts: a conveying section, a limiting section and a fixed section, and at the same time, slidably connecting the positioning wheel with the conveying roller through a through hole in the center thereof.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that when polishing wooden floors of different sizes, the position of the positioning wheel needs to be adjusted manually. There are a large number of positioning wheels, which need to be adjusted one by one, which is very inconvenient to operate and not convenient for the use of the polishing device. For this reason, we propose a wooden floor polishing device. Utility Model Content

[0017] As the preferred technical solution of this application,

[0018] The screw threads corresponding to the bottom of the two sets of mounting plates rotate in opposite directions. The adjacent sides of the two sets of mounting plates are fixedly connected to the limit plates.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] In the scheme of this application:

[0025] 1. The rotating rod and the second sprocket are driven to rotate by rotating the turntable, and the second sprocket drives the first sprocket and the connecting rod to rotate through the chain, and the connecting rod drives the screw to rotate. Since the thread directions of the screws on the front and rear sides are opposite, the screw can drive the corresponding moving block to move when it rotates, and the mounting plate and the movable plate are driven to move by the moving block. The movable plate drives the rotating rod to contact the wooden floor through the spring, so as to facilitate the adjustment of the position of the positioning plate according to wooden floors of different sizes, avoid the wooden floor from shifting during the transmission process, and facilitate the use of the grinding device.

[0026] 2. By setting the spring and the rotating rod, the positioning plate can be moved in the installation groove while positioning the wooden floor. When the positioning plate is completely moved into the installation groove, the limit plate will contact the wooden floor, and the limit plate will clamp the wooden floor to prevent the wooden floor from moving during the polishing process.
