Double-speed shifting belt turnover mechanism

The invention discloses a double-speed shifting belt turnover mechanism. The double-speed shifting belt turnover mechanism comprises an installation bottom plate and an installation bracket, the installation bracket is fixedly installed on the outer surface of the upper end of the installation bottom plate through bolts, linear guideways are fixedly installed at the positions, close to the two ends, of the outer surface of the upper end of the installation bracket, and turnover bases are movably installed on the linear guideways. According to the double-speed shifting belt turnover mechanism,a translation mechanism is simple in structure, small in occupied area and high in efficiency, human-machine operating station separation can be realized, a telescopic air cylinder, the linear guideways, gears and racks are coordinately used, more stability is achieved during operation, the gears and the racks are gathered and stacked under the driving of the telescopic air cylinder, double amplification of speed and stro
