CN203077808U - Eccentric wheel transmission device of full-automatic high-speed screen printer - Google Patents

Abstract

The utility model discloses an eccentric wheel transmission device of a full-automatic high-speed screen printer. A transmission mechanism comprises an upper connecting plate, two upper transmission connecting plates and two upper eccentric wheels. One end of the upper connecting plate is fixed with an upper template. The other end of the upper connecting plate is simultaneously hinged with one end of one upper transmission connecting plate and one end of the other upper transmission connecting plate. Upper rollers which are matched with the corresponding upper eccentric wheels in a linkage mode are respectively hinged with the other ends of the two upper transmission connecting plates. When one of the upper rollers moves to the highest point of one upper eccentric wheel, the other upper roller is located at the lowest point of the other upper eccentric wheel. A transmission mechanism which is used for driving a lower template to move up and down comprises a lower connecting plate, two lower transmission connecting plates and two lower eccentric wheels. One end of the lower connecting plate is fixed with the lower template. The other end of the lower transmission connecting plate is simultaneously hinged with one end of one lower transmission connecting plate and one end of the other lower transmission connecting plate. The other ends of the two transmission connecting plates are respectively hinged with lower rollers which are matched with the corresponding lower eccentric wheels in a linkage mode. When one of the lower rollers moves to the highest point of one lower eccentric wheel, the other lower roller is located at the lowest point of the other lower eccentric wheel. Due to the fact that eccentric wheels are used for replacing cams in a transmission mechanism, the eccentric wheel transmission device of the full-automatic high-speed screen printer has the advantages of enabling a walking path of transmission to be gentle and stable, improving stability of operation of machines, avoiding the situation that the transmission mechanism of the upper template and the transmission mechanism of the lower template are inconsistent in movement, being high in enduring rate of accuracy of printing, ensuring the quality of printing, enabling a printing process to be finished in one step, being good in stability of printing, obviously improving the quality of printing, saving resources, avoiding waste, and satisfying the requirement for rapid printing and the requirement for mass printing.

Description
