Automatic filling device for culture medium

Abstract

The invention discloses an automatic filling device for a culture medium. The automatic filling device comprises a machine box, a peristaltic pump, a control system and an operation panel. The machine box is provided with one or more first stations, second station holes formed corresponding to the one or more first stations, filling stations correspondingly arranged on a liquid outlet pipe below the second station holes and a plate pushing mechanism pushing empty plates from the first stations to the second station holes. A special first material frame and a special second material frame are adopted, the plate pushing mechanism is used for transferring the empty plates from the first stations on the bottom of the first material frame to the second station holes, namely empty plate waiting positions, a corresponding part of the lifting mechanism is used for descending to divide plate covers, then, the liquid outlet pipe carries out filling at the corresponding stations, after filling is completed, the corresponding part of the lifting mechanism ascends to jack full plates into the second material frame, and the full plates jacked into the second material frame are piled in the second material frame in a laminated manner under the action of a one-direction overturning material collection mechanism arranged on the bottom of the second material frame.

Description

technical field [0001] The invention relates to a culture medium automatic filling device used in the fields of pharmacy, food and beverage, disease control, chemical industry, cosmetics and the like. Background technique [0002] At present, most manufacturers adopt the following three methods for sub-packaging and filling of plates: [0003] Manual sub-packaging has low production efficiency, high cost, high risk of product contamination, and difficult to guarantee filling quality. [0004] Using a fully automatic sub-packaging production line for sub-packaging, although the need for personnel is less than that of manual labor, the production efficiency is high, but the cost of the equipment itself and the maintenance costs in the later period are high, which cannot meet most of the automatic filling of culture media, and the requirements for the environment are higher. Moreover, the equipment needs to occupy a relatively large workshop area, which causes a waste of resou...

Problems solved by technology

[0003] Manual sub-packaging, low production efficiency, high cost, high risk of product contamination, and difficult to guarantee filling quality

[0004] Using a fully automatic sub-packaging production line for sub-packaging, although the need for personnel is less than that of manual labor, the production efficiency is high, but the cost of the equipment itself and the maintenance costs in the later period are high, which cannot meet most of the automatic filling of culture media, and the requirements for the environment are higher. And the equipment needs to occupy a relatively large workshop area, which causes a waste of resources for small-batch production enterprises

[0005] Dispensing with a turntable type dispensing machine can theoretically solve the problems of high labor costs, unstable filling quality, excessive equipment volume, and high requirements. However, the current turntable type dispensing machine has the following problems:

[0006] 1. During the operation process, the turntable needs to reciprocate no matter whether the empty plate is placed or the full plate is lifted in. The reciprocating rotation of the large-mass turntable is likely to cause the plate to be stuck, or even to destroy the plate, further causing medium contamination. The equipment is clean, even causing problems such as microbial growth

2. To install an empty dish or remove a full dish, you need to take it from the top. Due to the high height of the machine, the turntable for stacking the plates is placed on the machine, and only the outer ring of the machine can place the plates. The volume of the entire device Both the weight and the weight will make it quite inconvenient for personnel to operate. After the full plate is stacked, the entire turntable needs multiple workers to carry it, otherwise the risk of tipping is very high.

[0007] 3. The filled plate is used for microbial inspection or monitoring, so the filled plate should be sterile in theory, but due to the relatively large volume of the turntable, it cannot be put into the sterilization box for sterilization, and manual disinfection is difficult

[0008] 4. During filling, because the plate cover and the plate are placed on the upper and lower turntable fixing frames, there is a gap in the fixing frame, and after the rotation and filling are completed, the lifting ejector rod does not position the plate, resulting in the jacking up to During the process of the large turntable above, it is prone to top bending, improper closing of the cover or even crushing.

[0009] 5. Since the blanking hole and the jacking hole of the existing turntable are adjacent to each other, the operating space is small. Once the dish jams or the interference between the full dish and the turntable occurs when the ejector rod rises, the plate will be crushed and the liquid will flow into the machine. It is very difficult to deal with the situation of Taiwan
