8. The automatic lid opening/closing device according to claim 1, wherein: the end edge of the material cover is provided with a sealing groove for installing a sealing element, and a sealing element for improving the sealing performance of the material cover is arranged in the sealing groove.
9. A control method of an automatic opening/closing device of a lid for controlling an automatic opening/closing device of a lid according to any one of claims 1 to 8, characterized by comprising the steps of:
(1) And (3) accessory installation:
a sensor I, a sensor II and a sensor III are arranged on the lock box and the telescopic cover opening mechanism;
(2) Automatic uncovering of the material cover:
firstly, the telescopic end of the telescopic uncapping mechanism is driven to shrink, at the moment, the non-installation end of the telescopic uncapping mechanism approaches the telescopic end of the telescopic uncapping mechanism, the sensor II is configured to control the shrinkage of the telescopic end of the stopping piece, namely the push-pull electromagnet, not to generate blocking interference with the moving piece when the sensor II detects that the moving piece approaches the stopping piece, and the telescopic end of the stopping piece, namely the push-pull electromagnet, is reset to an initial state when the stopping piece, namely the push-pull electromagnet completely passes over the moving piece, the sensor III is configured to stop shrinkage when the sensor III detects that the material cover is in a maximum opening state, and the uncapping action is completed, so that the feeding action can be carried out on the container mouth;
(3) Automatic closing of material cover:
firstly, the telescopic end of the telescopic uncapping mechanism is driven to stretch, at the moment, the non-installation end of the telescopic uncapping mechanism is far away from the telescopic end of the telescopic uncapping mechanism, when the sensor II detects that the moving part is close to the backstop part, the telescopic end of the backstop part, namely the push-pull electromagnet, contracts and does not generate blocking interference with the moving part, when the backstop part, namely the push-pull electromagnet completely passes over the moving part, the telescopic end of the push-pull electromagnet is reset to an initial state, the sensor I is configured to enable the sensor I to detect that the lock shaft stretches into the lock hole, the telescopic end of the telescopic uncapping mechanism is driven to stop stretching, and at the moment, the automatic opening and closing device of the material cover is in a cover closing locking state;
(4) Manual uncovering of the material cover:
first selecting down the locking mechanical system between lock box and the manual cover that intervenes to open, manually stirring manual cover that intervenes to open, the inner peripheral face of arc promotion groove promotes the cambered surface promptly and promotes the actuating lever drive end this moment to this telescopic end shrink that makes telescopic mechanism that uncaps, causes the lock axle to break away from the lockhole, realizes the unblock state of material lid, continues to stir manual cover that intervenes to open until the support inclined plane can open the material lid completely when contacting with the container mouth.
