Description

Technical Field

[0002] A freeze dryer is a device that dries substances by first freezing and then sublimating moisture under a vacuum state. Freeze drying, or lyophilization technology, is an advanced material dehydration technology, mainly used in the fields of bioengineering, pharmaceutical industry, food industry, etc. The automatic feeding and discharging structure of a freeze dryer is an efficient mechanical system used to achieve automatic loading and unloading of materials, so as to optimize the freeze drying process and reduce manual operation. An existing automatic feeding and discharging structure is to convey a storage rack on which articles to be dried are placed into the tank body of the dryer through an electric track, and after drying is completed, it is conveyed out through the electric track again. When in use, a section of the track is connected to the external track through a motor and a rotating shaft. When it is necessary to convey materials, the tank door is opened, and this section of the track will rotate by a certain angle and be spliced with the internal track of the tank body to facilitate feeding and discharging.

[0003] One end of this section of the track is connected to the external track of the tank body, and the other end is in a suspended state. When the storage rack moves on this section of the track, this section of the track will drop due to the action of gravity, making the operation of the storage rack unstable. After long-term use, it will cause damage to the track. Therefore, it is necessary to provide an automatic feeding and discharging structure of a freeze dryer to solve the above problems.

[0047] The feeding and discharging track further includes a first gantry 10 and a first track 11;

[0048] The first gantry 10 is fixed on the ground, and the first track 11 is fixed in the middle of the top of the first gantry 10;

[0049] The first gantry 10 plays a supporting role, and the first track 11 is used to convey materials;

[0050] The feeding and discharging track further includes a servo motor 14 and a rotating shaft 15;

[0051] The servo motor 14 is fixed at one end of the upper surface of the first track 11, and the output end penetrates through the upper surface of the first track 11.

[0053] Working principle:

[0054] When the second track 12 rotates and engages with the third track 13, the electric push rod 21 on the fixing plate 20 starts. The electric push rod 21 extends, driving the movement of the clamping block 22. The clamping block 22 moves into the through hole 26 in the fixing block 25. At the same time, the spring column 23 drives the trapezoidal block 24 to abut against the inner wall of the through hole 26.

[0055] This step can strengthen the connection between the second track 12 and the third track 13, improve stability, and reduce the probability of damage to the second track 12 due to long-term gravity.

[0063] Working principle:

[0064] When the storage rack moves to the second track 12, due to the gravity of the second track 12, the electric push rod 21 moves downward, driving the clamping block 22 to move downward. Restricted by the fixing block 25, the movable end of the electric push rod 21 receives a reverse upward force. At this time, the support rod 31 under the second gantry 30 presses the arc plate 32 firmly on the movable end of the electric push rod 21, and the rotation of the ball 33 is driven when the movable end of the electric push rod 21 expands and contracts.

[0065] This step can prevent the movable end of the electric push rod 21 from being damaged by the reverse force.
