A double-station encapsulation machine for plastic reagent bottles

Abstract

The present invention discloses a double-station encapsulation machine for plastic reagent bottles, which mainly consists of a feeding mechanism, a film unwinding mechanism, a film position adjustment device, a pressing and ironing device, a film winding mechanism, a re-ironing device, a bottle receiving mechanism, a turntable mechanism, and a liquid injection mechanism. The feeding mechanism sends two empty bottles into the turntable mechanism, and the turntable mechanism drives the empty bottles to move. The empty bottles first enter below the liquid injection mechanism, and the bottles filled with reagents enter the two pressing and ironing devices under the drive of the turntable mechanism. The film unwinding mechanism sends out the film, and the film continuously undergoes three adjustments of the plane conveying angle through the film position adjustment device. The film horizontally passes through the pressing and ironing device and the re-ironing device respectively, and the film piece is pressed and ironed on the bottle mouth. The film that is not pressed and ironed is collected by the film winding mechanism. The encapsulated reagent bottles enter the subsequent palletizing process through the bottle receiving mechanism. The present invention enables the film to change direction three times continuously through the film position adjustment device, ensuring that the film always remains in a horizontal state at the ironing and pressing working surface, and realizing double-station encapsulation.
