The operation of medical bottle caps is not so easy. If you don't, you will scratch your hands. How can you tighten the medical bottle caps? Put the bottle filled with liquid and put the lid on the lower tray, place it on the V-shaped support block, hold the bottle with one hand, and pull the handle backwards with the other hand to tighten it. Raise the tray upwards, and after the aluminum-plastic cap and capping head are closed, the three capping cutter heads that rotate non-stop rotate several times to tighten the cap. It is necessary for the motor to work clockwise. Push the handle forward to return the rolled aluminum-plastic cap to the original position with the tray. The whole operation process is completed. In the future, the above operation can be repeated every time a cap is rolled.
