So that upon rotation of the rotating disc 311, the three sets of sliders 313 are thus moved simultaneously inwards or outwards, so that the second tracks 4 are provided on said outer disc 312, in said second track 4 is arranged an adjustment assembly 41 comprising a first 411 and a second block 412 and an elastic element 413 connecting the first 411 and the second block 412, placing the first 411 and the second block 412 in the second track 4 in the natural state of the elastic element 413, while under the second block 412 is arranged a screw 4121, a matching nut 4122 is provided on the screw 4121, so that turning the nut 4122 can couple and fix the second block 412 in the second rail 4, a moving block 4111 is arranged at the bottom of the rotating disc 311, the moving block 4111 is connected with the first block 411, a pushing member 4112 is arranged on the first block 411, and the pushing member 4112 penetrates out of the second track 4.

Preferably, three groups of pushing assemblies 32 are circumferentially distributed right above the fixture 31, and the positions of the three groups of pushing assemblies 32 are staggered from the sliding block 313, each pushing assembly 32 comprises a rotating rod 322, a pushing rod 323, a gear 324 and a rack 325, the pushing rod 323 is in threaded connection with the rotating rod 322, a connecting block 3347 is fixedly connected to the pushing rod 323, and the connecting block 3347 is slidably connected to the upper side of the outer disc 312, so that the pushing rod 323 only slides up and down on the outer disc 312 under the action of the connecting block 3347, and therefore, when the rotating rod 322 rotates, the pushing rod 323 can move.

The placing plate 321 is installed on the three sets of rotating rods 322, preferably, the rotating rods 322 and the placing plate 321 are connected through a bearing, so that the rotating rods 322 can normally rotate, a gear 324 is arranged on the rotating rods 322, a torsion spring is arranged between the outer wall of the bearing and the gear 324, the rotating rods can keep still under the condition of no external force, one side of the gear 324 is meshed with a connecting rack 325, one end of the rack 325 is connected with a trigger 326, and an inclined surface 3261 is arranged on the trigger 326.

Meanwhile, a magnetic member 5 is arranged at the other end of the rack 325, an electromagnet 51 is arranged on one side of the magnetic member 5 and the placing plate 321, and the electromagnet 51 is generally controlled to be in an on or off state by remote control, preferably, the remote control can use infrared control. Meanwhile, the rack 325 preferably slides in a sliding groove on the placing plate 321, that is, the rack 325 can be lifted, and the racks 325 at different positions are engaged to adapt to cup covers with different sizes, so that the position of the trigger 326 can be adjusted.

The rotating component 33 comprises a rotating shaft 331 and a convex block 332, the workbench 2 is arranged at the bottom of the three sets of sliding blocks 313 and is arranged at the center of the rotating disc 311, then the rotating shaft is connected with the rotating disc 311, a curved groove 3311 is arranged on the rotating shaft 331, the convex block 332 is arranged on the curved groove 3311, the convex block 332 is connected with a baffle plate 333, the baffle plate 333 is connected with three sets of push rods 323, and when the push rods 323 drive the baffle plate 333 to move up and down, the convex block 332 is matched and displaced in the curved groove 3311 to realize the rotation of the rotating disc 311. A cover 6 is arranged outside the rotating assembly 33, the cover 6 is connected to the outer disc 312, and an output shaft of the rotating motor 1 is connected to the cover 6.

The working principle is as follows: firstly, adjusting the position of the slide block 313 to adapt to the size of the cup of the batch, loosening the nut 4122 of the second block 412, holding the push member 4112 below the first block 411, when moving left and right, the push member 4112 can drive the rotating disc 311 to rotate, when the rotating disc 311 rotates, the moving block 4111 slides in the slide bar 315, the slide block 313 slides inwards or outwards simultaneously in the groove 316, and when adjusting to just clamp the cup, the nut 4122 is rotated, so that the second block 412 is fixed on the second track 4;

then the rotating motor 1 is started, the rotating motor 1 drives the screwing device to rotate, simultaneously the cup body and the workbench 2 start to rotate, when the cup cover is covered on the cup body by holding the cup cover by hands, the cup cover starts to move downwards under the action of the threads, when the cup cover moves downwards to the last distance, the inclined surface 3261 of the trigger part 326 is contacted and extends outwards, the gear rack 325 rotates the gear 324, the gear 324 drives the rotating rod 322 to rotate, the rotating rod 322 rotates, the push rod 323 slides in the outer disc 312 through the connecting part, the push rod 323 moves downwards under the action of the threads, the push rod 323 drives the baffle 333 to move downwards, therefore, the lug 332 moves downwards in the curved groove 3311, the rotating disc 311 starts to rotate against the elastic force of the elastic part 413, and the slide 313 moves outwards at a small distance, namely not in a limiting cup body, therefore, the workbench 2 stops rotating under the condition of no acting force, and the cup cover and the cup body do not relatively continue to rotate, so that the over-tight connection is avoided;

remote control electro-magnet 51 starts, rack 325 moves to the outside, trigger 326 keeps away from the bowl cover, consequently stall motor 1 alright with the cup is taken out, improves packing efficiency, puts into the cup once more when on workstation 2, closes electro-magnet 51 under the effect of torsional spring, rack 325 resumes the normal position, simultaneously the cup will be pressed from both sides tightly, and above-mentioned operation of repetition can.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
