A double-layer automatic sand leveling equipment

Abstract

The invention relates to the technical field of grinding equipment, and discloses a double-layer automatic horizontal polishing device. The device comprises a bearing base plate, wherein the bearing base plate is respectively provided with a driving roller, a first driven roller, a second driven roller, a first motor for driving the driving roller, and a third driven roller; the third driven roller, the first driven roller and the second driven roller are interconnected by a transmission manner through liner strips. The device has the advantages that 1, the pressure is applied to a processing surface through a pressure applying device, so that the transmission performances of the first driven roller and the second driven roller can be improved, and the polishing efficiency can be obviously increased; 2, the direct stressing of an abrasive belt can be avoided through the pressure applying device, and thus the utilization rate of the abrasive belt is maximized; in a conclusion, the device has the advantages of being high in grinding efficiency, high in transmission performance, and long in service life of the abrasive belt.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a double-layer automatic sand leveling equipment. Background technique [0002] Sanding machine, also known as grinding machine, refers to the physical removal of some materials and objects with uneven surface, uneven thickness and non-conforming process requirements through abrasive cloth, grinding wheel, sandpaper, scouring pad, non-woven polishing wheel, etc. , to make it smoother, smoother, uniform in thickness, and to make it up to standard. It is widely used in the production of various veneers, the production of standard structural parts, the toy handicraft industry, the decoration and furniture industry, floor wall panels and building materials industry and so on. [0003] Existing sanding machines are mainly divided into three types: disc sanding, belt sanding and cloth wheel sanding. For the furniture manufacturing industry, belt sanding is often more suitab...

Problems solved by technology

The equipment can simultaneously grind the woods with different needs by driving the sand belt and the sand bar to rotate by a motor, which is convenient and practical, and improves the working efficiency of the machine; obviously, the first roller and the second roller in the above scheme It is necessary to drive the abrasive belt to directly contact the surface of the board. In the grinding of wood boards, it is often necessary to achieve different contact between the abrasive belt and the surface of the board according to different grinding requirements. For example, in the coarse sanding process, due to its polishing allowance It is relatively large, so a certain force must be applied to the abrasive belt to make it tightly attached to the surface of the board, but the above-mentioned grinder can only rely on the first roller and the second roller to apply pressure. If the first roller If the pressure exerted by the first roller and the second roller is too large, it will directly affect the transmission performance of the abrasive belt. Moreover, if the first roller and the second roller apply a large pressure for a long time, the first roller and the second roller will The second roller is prone to high temperature overheating, which has a great impact on the service life of the abrasive belt; in view of this, the inventor has provided a double-layer automatic sand flattening equipment after repeated research and experiments
