[0042] Specifically, the lid separating device 400 includes a rotating member 410 and a driving device 420 for driving the rotation of the rotating member 410. The rotating member 410 is disposed above the first conveying device 100. A plurality of lever rods 411 are annularly arranged on the rotating member 410 at intervals. The lever rods 411 are used to equally separate the lids 10 at equal intervals.

The small end of the conical section 221 is connected to the straight cylinder section 222. The conical section 221 is used to flip the lid 10 and guide the flipped lid 10 into the straight cylinder section 222.

[0046] Among them, the radial dimension of the straight cylinder section 222 is larger than the maximum radial dimension of the lid 10, so as to prevent the lid 10 from being stuck in the straight cylinder section 222. And, designers can adjust the taper of the conical section 221 according to actual needs so that the lid 10 can be flipped in the conical section 221, and no specific numerical restrictions are made here.

[0052] The compressed air buffer device can generate compressed air, and the compressed air can be blown into the straight cylinder section 222 along the compressed air outlet 500 to slow down the falling speed of the cover body 10, so that the cover body 10 can fall more stably from the flipping device 200 onto the first conveying device 100, thereby ensuring the quality of the cover body 10. Especially when the cover body 10 is a fresh-keeping cover after powder filling, the above effect is more significant.

[0053] Among them, the pressure of the compressed air should not be too large, and it is ensured that the cover body 10 just has a slight retention effect in the straight cylinder section 222. Preferably, the pressure of the compressed air is 0.01MPa - 0.05MPa.

[0054] The designer can adjust the specific structure of the compressed air buffer device according to the usage requirements, and no specific limitation is made here.

[0060] The designer can adjust the specific structure of the second conveying device 600 according to the usage requirements, and no specific limitation is made herein. Preferably, the second conveying device 600 is a conveyor belt.

[0063] When the cover body 10 is a fresh-keeping cover, the filled cover body 10 is conveyed to the transition structure 700 through the second conveying device 600. As the second conveying device 600 operates, the subsequent cover body 10 will squeeze the cover body 10 on the transition structure 700 to fall onto the flipping device 200. After the cover body 10 is flipped by the flipping device 200, the bottom of the cover body 10 will face upward and gently fall onto the first conveying device 100 through the compressed air buffer device.
