Freeze-drying machine and bottle inlet and outlet method of freeze-drying machine

Abstract

The invention discloses a freeze-drying machine and a bottle inlet and outlet method of the freeze-drying machine. The freeze-drying machine comprises a conveyor belt, a transition plate, a freeze-drying box, a bottle inlet assembly and a bottle outlet assembly, wherein the bottle inlet assembly comprises a front bottle pushing mechanism, the front bottle pushing mechanism is arranged in front of the freeze-drying box and is used for pushing bottles on the conveyor belt to the transition plate and then pushing the bottles into the freeze-drying box, the bottle outlet assembly comprises a back bottle pushing mechanism and a front bottle pulling mechanism, the back bottle pushing mechanism is arranged at the back of the freeze-drying box and is used for pushing the bottles out of the freeze-drying box to the transition plate, and the front bottle pulling mechanism is arranged in front of the freeze-drying box and is used for pulling the bottles on the transition plate to the conveyor belt. The bottle inlet and outlet method has the following steps that when the bottles are delivered in, the front bottle pushing mechanism in front of the freeze-drying box pushes the bottles on the conveyor belt to the transition plate and then pushes the bottles into the freeze-drying box; and when the bottles are delivered out, firstly, the back bottle pushing mechanism at the back of the freeze-drying box pushes the bottles out of the freeze-drying box to the transition plate, and then the front bottle pulling mechanism in front of the freeze-drying box pulls the bottles on the transition plate to the conveyor belt. The freeze-drying machine and the bottle inlet and outlet method have the advantages that the simplicity and the compactness are realized, and the space occupation is little.

Description

technical field [0001] The invention mainly relates to the field of pharmaceutical machinery, in particular to a freeze dryer and a method for feeding and discharging the freeze dryer. Background technique [0002] In the field of pharmaceutical machinery, a freeze dryer generally includes a conveyor belt, a transition plate, a freeze-drying box, a bottle inlet assembly and a bottle output assembly. to return the vials in the freeze-drying box to the conveyor belt. The bottle output assembly in EP0782686B1 adopts the rear push rod set at the rear of the freeze-drying box to push the bottle body in the freeze-drying box directly onto the conveyor belt, so the rear push rod must be set very long to meet the stroke requirements of pushing the bottle, resulting in The entire bottle output assembly takes up a lot of space; and there are generally cold traps and other components behind the freeze-drying box. In order to avoid interference between the cold trap and other component...

The bottle output assembly in EP0782686B1 adopts the rear push rod set at the rear of the freeze-drying box to push the bottle body in the freeze-drying box directly onto the conveyor belt, so the rear push rod must be set very long to meet the stroke requirements of pushing the bottle, resulting in The entire bottle output assembly takes up a lot of space; and there are generally cold traps and other components behind the freeze-drying box. In order to avoid interference between the cold trap and other components and the rear push rod, the setting position of the cold trap and other components can only be changed, which will lead to structural failure. complex

CN200580018914 provides a multi-joint chain push-type bottle output assembly, which pushes and conveys the bottle body through a multi-joint hinged member wound on the sprocket, which can significantly reduce the overall size of the bottle output assembly, but The structure is relatively complex, and due to the connection gap between the hinged components, the bottle body is not stable enough to be pushed, and the conveying position of the bottle body is not accurate enough
