Polishing machine

Abstract

The invention discloses a polishing machine. The polishing machine comprises a machine frame, wherein multiple mills are installed on the machine frame, conveying roller sets are arranged at the feeding end and discharging end of the each mill, each conveying roller set comprises an upper conveying roller and a lower conveying roller, a main motor is installed on the machine frame, a working table used for supporting a steel plate to be machined is arranged between the feeding end and discharging end of each mill, and grinding head assemblies corresponding to the working tables are arranged on the machine frame. Each grinding head assembly comprises a sliding frame, a polishing motor and a polishing brush driven by the polishing motor to rotate, wherein the sliding frame is driven by a swing motor fixedly installed on the machine frame. The mesh numbers of the polishing brushes of the multiple mills become larger gradually from the feeding end to the discharging end of the machine frame. An injection pipe parallel to the corresponding conveying roller sets is installed on each mill, and multiple injection holes are formed in each injection pipe corresponding to the corresponding working table. Due to the fact that the mesh numbers of the polishing brushes of the multiple mills become larger gradually, polishing process requirements can be met at a time, and reciprocating scratching caused by repeated passing of the steel plates is avoided.

Description

technical field [0001] The invention relates to a polishing machine for polishing plate-shaped materials. Background technique [0002] In the field of medicine, the steel plate for making tanks needs to be polished in advance. In order to make the surface of the steel plate reach a certain degree of smoothness, it is necessary to use multiple levels of polishing machines for multiple grinding and polishing. Therefore, the steel plate to be polished needs to be transported many times, and each time When polishing, it needs to be in contact with the discharge rack at the inlet and outlet end of the polishing machine. The more polishing stages, the more contact times between the steel plate and the feed rack, which greatly increases the possibility of scratches on the surface of the steel plate, which may result in passing through the last stage. There are still large scratches on the surface of the ground and polished steel plate, which affects the quality of the steel plate,...

[0002] In the medical field, the steel plate for making tanks needs to be polished in advance. In order to make the surface of the steel plate reach a certain degree of smoothness, it is necessary to use multiple levels of polishing machines for multiple grinding and polishing. Therefore, the steel plate to be polished needs to be transported many times, and each time When polishing, it needs to be in contact with the discharge rack at the inlet and outlet end of the polishing machine. The more polishing stages, the more contact times between the steel plate and the feed rack, which greatly increases the possibility of scratches on the steel plate surface, which may lead to There are still large scratches on the surface of the ground and polished steel plate, which will affect the quality of the steel plate, and then affect the quality of the tank body, which will easily cause customer dissatisfaction

Moreover, at present, polishing brushes are used for dry grinding during grinding and polishing. This grinding method leads to large dust in the workplace, which seriously affects the health of operators, and the accuracy of dry grinding is poor. Even after more stages of polishing, the steel plate surface The smoothness is also not up to the high standard
