the inner wall of the container body (22) is provided with a ring plate (223), and the cover plate (211) is supported on the ring plate (223).

10. An automated cover-removing device for use with a packaging container according to any one of claims 1 to 9, comprising:

a fixed frame (12), a lifting driving mechanism (14) and a cover taking mechanism,

the cover taking and sealing mechanism comprises a mounting frame (15), a rotary driving mechanism (16) and a cover plate grabbing mechanism (11),

the rotary driving mechanism (16) and the cover plate grabbing mechanism (11) are both arranged on the mounting frame (15),

the lifting driving mechanism (14) is connected between the fixed frame (12) and the mounting frame (15) and is used for driving the cover taking mechanism to lift so as to enable the rotary driving mechanism (16) to be connected with or disconnected from the rotary table (2132),

the rotation driving mechanism (16) is used for driving the rotary table (2132) to rotate so as to enable the first connecting part (2136) to be connected with or disconnected from the second connecting part (221),

the cover plate grabbing mechanism (11) is used for grabbing or releasing the cover plate (211).

11. An automatic cap taking and sealing system comprises a packaging container and an automatic cap taking and sealing device, and is characterized in that,

the packaging container comprises a container body (22) and a cover body (21),

the rotary table (2132) is rotatably connected with the central position of the upper surface of the cover plate (211),

when the rotary table (2132) rotates, the driven mechanism (213) can be driven to rotate around the hinged point of the driven mechanism, so that the other end of the driven mechanism (213) is close to or far away from the rotary table (2132), when the other end of the driven mechanism (213) is far away from the rotary table (2132), the driven mechanism drives the first connecting portion (2136) to move towards the second connecting portion (221) to be connected with the second connecting portion (221), and when the other end of the driven mechanism (213) is close to the rotary table (2132), the driven mechanism drives the first connecting portion (2136) to release the connection with the second connecting portion (221);

the automatic seal cover taking device comprises a fixed frame (12), a lifting driving mechanism (14) and a seal cover taking mechanism,

12. A method of automatically removing closures in an automatic closure removal system as claimed in claim 11, comprising:

s1: taking a cover:

s1.1: the lifting driving mechanism (14) drives the cap taking mechanism to descend until the rotating driving mechanism (16) is connected with the turntable (2132),

s1.2: the rotation driving mechanism (16) drives the turntable (2132) to rotate so as to disconnect the first connecting part (2136) and the second connecting part (221),

s1.3: the cover plate grabbing mechanism (11) grabs the cover plate (211), and the lifting driving mechanism (14) drives the cover taking mechanism to ascend so as to drive the cover body (21) to ascend;

s2: and (4) capping:

s2.1: the lifting driving mechanism (14) drives the cover taking and sealing mechanism for grabbing the cover body (21) to descend until the cover body (21) seals the upper end opening of the container body (22),

S2.2: the rotation driving mechanism (16) drives the turntable (2132) to rotate reversely so as to connect the first connecting part (2136) with the second connecting part (221),

s2.3: the cover plate grabbing mechanism (11) releases the cover plate (211), and the lifting driving mechanism (14) drives the cover taking mechanism to ascend.
