Description

Technical Field

[0001] The utility model relates to the technical field of biomedical related equipment, in particular to a valve opening and closing device. Background Art

[0002] At present, in the cell and gene therapy industry, in the preparation packaging process, the three liquids of cell solution, diluent and freezing solution need to be mixed before the next step of packaging can be carried out to make smaller units of final product bags. The existing packaging methods all use pinch valves to press the pipeline to achieve pipeline opening and closing, and the operator needs to press the pipeline into the pinch valve one by one. When the number of packaging bags is large, such as 20 bags, the packaging is troublesome and inconvenient to operate. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a valve opening and closing device, which can control the on and off of the pagoda valve, reduce the workload, and greatly improve the packaging efficiency. The technical solution adopted by the utility model is:

[0004] A valve opening and closing device comprises a mounting plate, N rotating heads and N steering gears driving the rotating heads one by one, wherein the rotating heads are located on the front side of the mounting plate and the steering gears are located on the back side of the mounting plate, wherein the rotating heads can clamp the valves of the pagoda-connected valves and rotate the valves under the drive of the steering gears to realize opening or closing; N is a natural number and N≥1.

[0005] In the valve opening and closing device, the rotating head is provided with four evenly distributed clamping blocks, and a clamping groove is formed between each clamping block, so that a cross-shaped clamping groove can clamp the valve.

[0006] The valve opening and closing device is provided with a ball plunger on each clamping block to support the valve.

[0007] The beneficial effects of the utility model are as follows: the opening and closing device can realize the automation of valve opening and closing, and each valve is individually controlled to open and close, and multiple valves can be controlled, which greatly improves the efficiency of bag filling.

[0012] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.

[0013] This embodiment is a valve opening and closing device, comprising a mounting plate 1, N rotating heads 2 and N steering gears 3 driving the rotating heads 2 one by one, the rotating heads 2 are located on the front of the mounting plate 1, and the steering gears 3 are located on the back of the mounting plate 1, the rotating heads 2 can clamp the valve 4 of the pagoda valve and rotate the valve 4 under the drive of the steering gears 3 to open or close, and the valve 4 is a consumable. In this embodiment, the number of bags in the packaging machine is 20 bags, and the opening and closing device N=10, so two sets of the opening and closing devices can be configured in the packaging machine.

[0014] Specifically, Figure 3 As shown, the rotating head 2 is provided with four clamping blocks 21 distributed in a cross shape, and a clamping groove 22 is formed between each clamping block 21, so that the cross-shaped clamping groove can clamp the valve 4. In order to further improve the clamping force, a ball head plunger 23 is installed on each clamping block 21 to support the valve 4, so that the rotating head 2 can clamp the valve 4 more stably.
