Bottle in and out assembly for freeze-drying box and bottle in and out method

Abstract

The invention discloses a bottle go-in and go-out assembly and method used for a freeze-drying box. The bottle go-in and go-out assembly used for the freeze-drying box comprises a bottle push-pull component and further comprises a rear bottle pushing plate, wherein the bottle push-pull component is driven by a push-pull rod to push bottles in and pull bottles out, the rear bottle pushing plate is used for pushing bottles out of the freeze-drying box, a connecting pull rod extending in the bottle go-out direction is connected to the rear bottle pushing plate, and the push-pull rod can be connected to or separated from the connecting pull plate through a separation and reunion mechanism. The bottle go-in and go-out method for the freeze-drying box includes the steps that when bottles go in, bottles on a conveying belt are pushed into the freeze-drying box from the front of the freeze-drying box; when bottles go out, first, the rear bottle pushing plate is pulled from the front of the freeze-drying box to push the bottles out of the freeze-drying box for a certain distance, and then the bottles are pulled out to the conveying belt. The bottle go-in and go-out assembly for the freeze-drying box has the advantages of being simple and compact in structure, easy to machine, small in occupied space and the like.

Description

technical field [0001] The invention mainly relates to the field of packaging machinery for medicine, food, etc., in particular to a bottle-in-out assembly and a bottle-in-out method for a freeze-drying box. Background technique [0002] At present, there are mainly two types of bottle inlet and outlet components for the freeze-drying box on the freeze-drying machine. One is to set a bottle pushing part driven by a push rod at the front and rear of the freeze-drying box, which are used for bottle entry and bottle exit respectively. , the structure of this bottle in and out assembly is complex and takes up a lot of space; and because a cold trap and other devices are installed behind the freeze-drying box, it will interfere with the bottle pushing parts. Another kind is to only arrange a push-pull bottle part in the front of the freeze-drying box, the bottle body can be pushed into the freeze-drying box to realize the bottle entry, and the bottle body can be pulled out from t...

Problems solved by technology

[0002] At present, there are mainly two types of bottle inlet and outlet components for the freeze-drying box on the freeze-drying machine. One is to set a bottle pushing part driven by a push rod at the front and rear of the freeze-drying box, which are used for bottle entry and bottle exit respectively. , the structure of this in-out bottle assembly is complex and takes up a lot of space; and because a cold trap and other devices are installed behind the freeze-drying box, it will interfere with the bottle-pushing parts

Another kind is to only arrange a push-pull bottle part in the front of the freeze-drying box, the bottle body can be pushed into the freeze-drying box to realize the bottle entry, and the bottle body can be pulled out from the freeze-drying box to realize the bottle discharge. Because of its long stroke, the bottle assembly needs to be equipped with a very long push-pull rod, which takes up a lot of space; and in order to stretch into the freeze-drying box with limited space to pull the bottle, the push-pull rod needs to be set very thin, so the rigidity of the push-pull rod is difficult Guaranteed, and difficult to process
