本发明属于自动化烹饪设备领域，涉及一种多通道蠕动泵，还涉及一种多通道蠕动泵控制方法。The invention belongs to the field of automatic cooking equipment, relates to a multi-channel peristaltic pump, and also relates to a multi-channel peristaltic pump control method.
背景技术Background technique
目前我国有许多样式的蠕动泵，通常使用在流量测量仪器、医疗器械、化工行业、制药行业中，常需要使用蠕动泵担任对试剂、样品或反应混合物的定量吸取等功能。现有技术中的蠕动泵基本是将滚柱直接安装在滚框上，当滚框转动时带动滚柱随着滚框公转，且滚柱自身也进行旋转，而滚柱在公转和自转过程中其中一些滚框会对泵管产生挤压和释放，从而能够起到泵送作用。然而，在滚柱挤压泵管过程中，如果泵管的出口发生堵塞，滚柱还会不停止地挤压泵管，很可能造成泵管内压力过大而出现崩裂现象，从而使蠕动泵损坏。而且市场上现有蠕动泵只有单泵管或是固定多泵管产品，大多都是同时对所有泵管进行挤压释放，缺乏可拓展性与灵活性，无法从多路中单独选择一路进行操作。At present, there are many types of peristaltic pumps in our country, which are usually used in flow measuring instruments, medical equipment, chemical industry, and pharmaceutical industry. Peristaltic pumps are often used for quantitative absorption of reagents, samples or reaction mixtures. The peristaltic pumps in the prior art basically install the rollers directly on the roller frame. When the roller frame rotates, the rollers are driven to revolve with the roller frame, and the rollers themselves also rotate, and the rollers are in the process of revolution and rotation. Some of these roller frames squeeze and release the pump tubing to allow pumping. However, during the process of the roller squeezing the pump tube, if the outlet of the pump tube is blocked, the roller will continue to squeeze the pump tube, which may cause the pump tube to burst due to excessive pressure, thus damaging the peristaltic pump. . Moreover, the existing peristaltic pumps on the market only have a single pump tube or fixed multi-pump tube products, most of which squeeze and release all the pump tubes at the same time, lack of scalability and flexibility, and cannot select one of the multiple channels for operation .
