Problems solved by technology

When the rubberized surface wears to a certain extent, the pallet will rub against the board surface, and even clamp the board to death, causing the board to stop
Moreover, the elastic coupling used to connect adjacent reducers is easily damaged. Even if it is connected with a universal cross shaft, it will be easily twisted due to the large torque, which is not conducive to popularization.

Abstract

The invention relates to a low roller driving type sander belonging to the technical field of mechanical processing equipment and comprising a driving device, a transmission part, a speed reduction machine and rubber coating transport roller external elements. The transmission part is connected between the driving device and the speed reduction machine. The low roller driving type sander is characterized in that each rubber coating transport roller external element comprises a gear box and at least two rubber coating transport rollers; one side of the gear box is connected with the speed reduction machine, and the other side of the gear box is connected with a rubber coating transport roller; at least two groups of rubber coating transport roller external elements are provided, the gear box of each rubber coating transport roller external element is provided with a coupler; and transmission shafts are additionally installed between the couplers. The invention can bear larger torque moment, has small occupied space and compact layout, largely reduces the phenomena of plate seizing and plate stopping, and prolongs the service life while reducing the failure rate.

Description

technical field [0001] The invention relates to a sander, in particular to a lower roller driven sander, which belongs to the technical field of mechanical processing equipment. Background technique [0002] At present, the widely used sanding machine in the market is to rely on the reverse rotation of the upper and lower paired rollers to drive the plate to convey the plate horizontally and straightly. The surface of the lower roller is covered with rubber or polyurethane to improve friction and has certain elasticity. Does not damage the surface of the board. Looking further, there are two forms of joint drive of the upper and lower rollers and separate drive of the lower roller, especially the single drive of the roller is more commonly used. [0003] However, the existing working space requires the reducer of the sander to be relatively small in size, which will result in a smaller input power and a correspondingly smaller output torque of the reducer. Moreover, due to...
