The working principle of the invention is as follows:
1. in the initial state (shelf 14 is fixedly connected with housing 1, knife wheel transmission rod 5 is connected with housing 1 by pin D51, track plate 3 is fixedly connected with housing 1 by pin B37, knife wheel connection rod 56 is connected with knife wheel transmission rod 5 by pin E53, slide block 52 is connected with inner ring A2 and inner ring B21 by slide block pin 522, inner ring A2 is fixedly connected with inner ring B21 by pin A12, knife wheel 55 is connected with knife wheel connection rod 56 by knife wheel shaft 551, round pin C561 on knife wheel connection rod 56 slides in arc track hole 39 of track plate 3, arc track plate 13 is fixedly connected with housing 1 by fixing pin 132, round pin B333 slides in arc track groove 131 of arc track plate 13, the center of arc track groove 131 is on the axis of bottle mouth sleeve 341, return spring A221, return spring B31, return spring C331, return spring D41 and return spring E543 is in the no-load state, round pin A15 is at the rightmost end in the groove of rack button 4, the ratchet wheel 24 is meshed with the pawl A44, the upper cam of the bidirectional cam 23 is contacted with the baffle A222, the ratchet wheel 24 is coaxially and fixedly connected with the friction wheel B241, the bidirectional cam 23 is coaxially and fixedly connected with the friction wheel A231, one end of the torsion spring 54 is fixedly connected with the knife wheel transmission rod 5, the other end of the torsion spring is fixedly connected with the torsion spring plectrum 541, the torsion spring plectrum 541 is slidably connected with the guide rod 542 through a plectrum hole 58, the two ends of the guide rod 542 are fixedly connected with the knife wheel connecting rod 56, the reset spring E543 is sleeved on the guide rod 542, and the two ends of the reset spring E543 are respectively connected with the knife wheel connecting rod 56 and the torsion spring plectrum 541. ) The upper end of the ampere bottle is inserted into the bottle opening sleeve 341 (the inside is made of rubber) from the bottle placing opening 38, and the thimble 35 is rotated to a proper position (the thimble 35 is in threaded connection with the lower pressing slider 34, and stepless adjustment is achieved).
2. When the rack button 4 is pressed inwards, the pawl a44 drives the ratchet wheel 24 and the friction wheel B241 to rotate anticlockwise and drives the friction wheel a231 to rotate clockwise, so that the bidirectional cam 23 rotates clockwise, the upper cam of the bidirectional cam 23 presses the baffle a222, and the inner ring A2 is driven to rotate anticlockwise. Under the action of the slider 52, the knife flywheel transmission rod 5 contracts towards the inner ring to drive the knife flywheel connecting rod 56 to contract inwards along the arc-shaped track hole 39, so that the knife flywheel 55 is in contact with the bottleneck of the ampere bottle (the knife flywheel connecting rod 56 and the knife flywheel transmission rod 5 are transmitted through the torsion spring 54, the torsion spring plectrum 541 and the pawl B545), and the ampere bottle can be adaptive to different bottleneck sizes. The rack button 4 is continuously pressed, the inner ring A2 continuously rotates anticlockwise, the knife flywheel connecting rod 56 and the knife flywheel transmission rod 5 form a certain angle, the knife flywheel 55 exerts pressure on the bottleneck, when the pressure reaches a certain degree, the torsion spring plectrum 541 deforms, and slides from the first pawl B545 to the second pawl B545 (at the moment, the included angle between two torsion arms of the torsion spring 54 is reduced, so that the torque between the knife flywheel connecting rod 56 and the knife flywheel transmission rod 5 is reduced, and further, the pressure of the knife flywheel 55 on the bottleneck of the ampere bottle is reduced), if the pressure of the knife flywheel connecting rod 56 and the knife flywheel transmission rod 5 is increased again, the torsion spring plectrum 541 slides to the next pawl B545, the pressure of the knife flywheel 55 on the bottleneck is ensured to be constant near a certain specific value, and the bottleneck of the ampere bottle is ensured not to be crushed by the knife flywheel 55.
3. Rack button 4 moves to resilient ball 251 at which point bidirectional cam 23 rotates exactly 90 deg., and the cam on bidirectional cam 23 pushes against barrier a222, maximizing the degree of counterclockwise rotation of inner ring A2. The shell 1 or the ampere bottle is rotated to scratch a complete grinding scratch on the bottleneck of the ampere bottle.
4. Continuing to press rack button 4, as rack button 4 moves to the bottom (round pin a15 moves to the leftmost end of the slot in rack button 4), at this point, bidirectional cam 23 rotates exactly 180 °, and the lower cam of bidirectional cam 23 contacts stop B332. The baffle A222 returns to the original position under the thrust of the return spring A221, the inner ring A2 rotates clockwise, the inner ring A2 drives the knife flywheel transmission rod 5 to expand outwards through the slider 52 and return to the original position, the knife flywheel connecting rod 56 returns to the original position along the arc-shaped track hole 39 (under the thrust of the return spring E543, the torsion spring plectrum 541 returns to the first pawl B545), and the knife flywheel 55 is separated from the bottleneck of the ampere bottle.
5. The rack button 4 is released, and the rack button 4 resets: the rack button 4 returns to the original position to the left by the urging force of the return spring D41 (the pawl a44 rotates clockwise around the pawl pin a42 to compress the pawl spring a43, and the pawl a44 hardly applies force to the ratchet wheel 24 and the ratchet wheel 24, the friction wheel a231, the friction wheel B241 and the bidirectional cam 23 do not rotate when the rack button 4 returns to the left because the elastic coefficient of the pawl spring a43 is small). The ampoule is broken off to open the ampoule, and at this time, the waste material at the upper end of the ampoule is located inside the ampoule opening sleeve 341.
6. The device is moved over the recovery bucket. The rack button 4 is pressed again, and when the rack button 4 moves to the elastic ball 251, the bidirectional cam 23 rotates by 90 °, and the lower cam of the bidirectional cam 23 presses the stopper B332, so that the upper toothed ring 33 rotates counterclockwise around the axis of the mouthpiece sleeve 341 (the upper toothed ring 33 is fitted around the outer edge of the mouthpiece sleeve 341). The upper toothed ring 33 extrudes the lower toothed ring 32 downwards (the lower toothed ring 32 is fixedly connected with the lower pressing slide block 34 through the nut 321, the lower pressing slide block 34 is in threaded connection with the thimble 35), the lower toothed ring 32 drives the thimble 35 to move downwards in the bottleneck sleeve 341, and the waste material at the upper end of the ampere bottle is ejected out of the bottleneck sleeve 341 and falls into the recycling bin, so that the waste material is collected. Continuing to press the rack button 4, when the rack button 4 moves to the bottom, at this time, the bidirectional cam 23 rotates 180 degrees, the upper cam of the bidirectional cam 23 contacts the baffle a222, the baffle B332 returns to the original position under the action of the return spring C331, the upper toothed ring 33 rotates clockwise around the axis of the mouthpiece sleeve 341 to return to the original position, and the lower toothed ring 32 returns to the original position under the action of the return spring B31.
