Description

Technical Field

[0001] The utility model relates to the technical field of nuclear pore membrane production, in particular to an anti-extrusion type nuclear pore membrane component pressing device. Background Art

[0002] Nuclear pore membranes are widely used in electronics, food, chemistry, pharmaceuticals and other industries, as well as biology, medicine, environmental science, analysis and testing. In the food industry, the nuclear pore membrane assembly can be pressed tightly, so that the nuclear pore membrane mother and child parts are fixed in the matching buckle clips to obtain a qualified nuclear pore membrane assembly, and then the nuclear pore membrane assembly is fixed at the installation position of the box. The nuclear pore membrane assembly can not only adjust the breathing intensity of the fresh food inside the box, but also adjust the temperature and humidity of the fresh storage environment in the box, so that the fresh food can be stored fresh. When the nuclear pore membrane assembly is pressed tightly, most of the existing devices place the nuclear pore membrane mother and child parts in the matching buckle clips, and then place the buckle clips under the pressing mold. The worker then starts the pressing device by controlling the foot, so that the pressing mold presses the nuclear pore membrane assembly. However, in actual use, since the hands and feet need to be used in coordination, the coordination of hands and feet is weakened after working for a long time, which makes it easy to squeeze the hands of the workers during use. In view of this situation, the existing device installs the controller next to the pressing device, so that the workers use their hands to press the controller, thereby reducing the problem of squeezing the hands of the workers. However, in actual work, when the worker controls the pressing device with one hand, the other hand needs to load and unload the materials. In the gap between loading and unloading, much time will be wasted, thus affecting production efficiency.

[0003] Based on this, an anti-extrusion nuclear pore membrane assembly pressing device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
