A positive and negative pressure separation mechanism of a heating plate of a paper tray forming hot press

Abstract

The utility model relates to the technical field of paper tray forming hot press, put forward a kind of paper tray forming hot press heating plate's positive pressure separation mechanism, including the connecting pipe being arranged on heating plate, negative pressure connector for connecting the input end of suction mechanism and positive pressure connector for connecting the output end of blowing mechanism are equipped on the connecting pipe;Negative pressure connector and positive pressure connector are independently spaced apart and arranged on the connecting pipe to form positive pressure separation mechanism;Heating plate is equipped with the air hole being connected with connecting pipe;Under the start of suction mechanism, the gas in heating plate is discharged in turn through air hole, connecting pipe, suction connector and suction mechanism, so that heating plate forms negative pressure and adsorbs product;Under the start of blowing mechanism, gas is blown out in turn through blowing mechanism, positive pressure connector, connecting pipe and air hole, so that product attached on heating plate falls off.Suction mechanism and blowing mechanism work independently through corresponding connector, so that hot vacuum gas does not liquefy due to the rapid cooling of positive pressure gas, and the yield is ensured.
