As shown in fig. 1, a driving mechanism 200 and a transmission mechanism 300 are disposed in a casing 100, a main shaft 400 is arranged in the casing 100 in a penetrating manner along the up-down direction, wherein a driving wheel 410 and a first cutting wheel 420 are sleeved on the main shaft 400, the driving wheel 410 is disposed in the casing 100, the first cutting wheel 420 is disposed outside the casing 100, and the driving mechanism 200 drives the driving wheel 410 to rotate through the transmission mechanism 300. The eccentric wheel 500 is sleeved on the main shaft 400, and the circumference of the eccentric wheel 500 is provided with a gear tooth segment 510, and as shown in fig. 2 and 4, the clockwise downstream end of the gear tooth segment 510 is provided with a first elastic piece 511. The idler 600 is rotatably disposed within the housing 100, and the idler 600 is in driving engagement with the drive wheel 410. The sliding plate 700 is slidably disposed at the lower end of the housing 100, the sliding plate 700 is in transmission connection with the eccentric wheel 500, the sliding plate 700 is provided with a second cutting wheel 520, the cutting wheel is located at the outer side of the housing 100, the second cutting wheel 520 corresponds to the first cutting wheel 420, and when the eccentric wheel 500 rotates, the second cutting wheel 520 can be driven to approach and separate from the first cutting wheel 420.
In the feeding state, the driving mechanism 200 drives the driving wheel 410 to rotate through the transmission mechanism 300, and the driving wheel 410 drives the idle wheel 600 to rotate, so that the idle wheel 600 drives the eccentric wheel 500 to synchronously rotate, and the eccentric wheel 500 drives the second cutting wheel 520 to move towards the direction approaching to the first cutting wheel 420 under the driving of the idle wheel 600. In the can-opening cutting state, one end of the gear tooth segment 510 far away from the first elastic piece 511 abuts against the idler wheel 600, and since the gear tooth at one end of the gear tooth segment 510 far away from the first elastic piece 511 cannot mesh with the idler wheel 600 to rotate, slipping occurs between the idler wheel 600 and the eccentric wheel 500, the eccentric wheel 500 is kept stationary under the abutting action of the first elastic piece 511 and the shell 100, and the first cutting wheel 420 and the second cutting wheel 520 are kept clamped on the can edge in a clamping mode. In the retracting state, the first elastic member 511 on the eccentric wheel 500 releases the elastic force, the eccentric wheel 500 rotates counterclockwise and rotates in engagement with the idle wheel 600, and the second cutting wheel 520 moves leftwards under the driving of the eccentric wheel 500 to pull the gap with the first cutting wheel 420, thereby completing the retracting action.
Therefore, through the cooperative operation of the driving wheel 410, the eccentric wheel 500 and the idle wheel 600, the first cutting wheel 420 and the second cutting wheel 520 can complete automatic feeding and retracting, the driving wheel 410 transmits the running speed to the eccentric wheel 500 through driving the driving gear 610 and the driven gear 620 with different diameters, so that the skidding speed of the eccentric wheel 500 is higher than the rotating speed of the driving wheel 410, and the first cutting wheel 420 and the second cutting wheel 520 can keep a stable rigid gap in the cutting process, so that the first cutting wheel 420 and the second cutting wheel 520 keep clamping the can edges, thereby completing the cutting action and improving the stability and reliability of can opening cutting.
It should be noted that, in the gear transmission system, if teeth of two gears are not completely exactly engaged or are affected by external torque, relative slip may occur between the gears, which is referred to as slipping of the gears, and the slip speed of the gears refers to a speed at which relative slip occurs between the gears due to friction. In this embodiment, the gear tooth segment 510 of the eccentric wheel 500 and the idle wheel 600 slip, and the driving gear 610 has a smaller diameter than the driven gear 620, so that the driving speed of the driving wheel 410 is lower than the slip speed of the eccentric wheel 500 when the driving wheel 410 rotates the eccentric wheel 500 through the idle wheel 600.
In this embodiment, as shown in fig. 1, the eccentric wheel 500 is located at the lower side of the driving wheel 410, the driving gear 610 is coaxially disposed at the upper end of the driven gear 620, where the diameter of the driving wheel 410 is larger than that of the eccentric wheel 500, the diameter of the driving gear 610 is smaller than that of the driven gear 620, the driving gear 610 is meshed with the driving wheel 410, the driven gear 620 can be meshed with the gear tooth segment 510 of the eccentric wheel 500, then in the can opening cutting state, the driving mechanism 300 drives the driving wheel 410 to rotate clockwise, the driving wheel 410 is meshed with the driving gear 610 and drives the driving gear 610 to rotate counterclockwise, meanwhile, the driven gear 620 and the driving gear 610 synchronously rotate to drive the eccentric wheel 500 to rotate clockwise, the eccentric wheel 500 drives the second cutting wheel 520 to approach the first cutting wheel 420 under the driving of the idle wheel 600, when the end of the eccentric wheel 500 rotates until the gear tooth segment 510 abuts against the driven gear 620, the driven gear 620 slides against the eccentric wheel 500, and at this time, the eccentric wheel 500 is kept stationary under the abutting action of the first elastic piece 511 and the housing 100, and the second cutting wheel 520 and the first cutting wheel 420 form a stable rigid gap, and clamp a can.
In this embodiment, the drive mechanism 200 is an electric motor.
In some embodiments of the present invention, the operating speed of the first cutting wheel 420 ranges from 10rpm to 25rpm, with the operating speed of the idler wheel 600 being greater than 25rpm.
It should be noted that, in the case of can opening cutting, the slip of the idler gear 600 may result in a higher transmission ratio with the eccentric gear 500 than the first cutting wheel 420, so that the slip speed of the eccentric gear 500 is higher than the running speed of the cutting wheel. In this particular embodiment, the operating speed of the idler wheel 600 is 48rpm and the operating speed of the first cutting wheel 420 is 17rpm, such that the operating speed of the idler wheel 600 is greater than the operating speed of the first cutting wheel 420, and at this speed differential, there is little opportunity for the first and second cutting wheels 420, 520 to pull apart the cutting gap, thereby ensuring that the first and second cutting wheels 420, 520 are able to maintain a rigid gap while cutting.
In some embodiments of the present invention, eccentric 500 is coupled to sled 700 via a double ring plate 710, and double ring plate 710 converts rotational motion of eccentric 500 into linear motion of sled 700.
As shown in fig. 6 to 8, the double-ring plate 710 has two through holes disposed along the up-down direction, the eccentric wheel 500 is in transmission connection with the sliding plate 700 through the double-ring plate 710, specifically, one end of the double-ring plate 710 is sleeved on the sliding plate 700, i.e. one through hole of the double-ring plate 710 is sleeved on the corresponding cylindrical protrusion of the sliding plate 700, so that the double-ring plate 710 can rotate relative to the sliding plate 700, the other end of the double-ring plate 710 is sleeved on the eccentric wheel 500, i.e. the other through hole of the double-ring plate 710 is sleeved on the lower end of the eccentric wheel 500, and the sliding plate 700 can only move linearly along the left-right direction under the limit of the housing 100. Thus, the double ring plate 710 converts the rotation of the eccentric 500 into the left and right movement of the sliding plate 700, so that the second cutting wheel 520 can make a straight line movement in the left and right direction to achieve approaching and separating from the first cutting wheel 420.
Further, the second cutting wheel 520 is obliquely disposed on the sliding plate 700, whereby the forward rotation and the reverse rotation of the driving mechanism 200 can drive the second cutting wheel 520 to approach and depart from the first cutting wheel 420 through the eccentric wheel 500, the double-ring plate 710, and the sliding plate 700, and the obliquely disposed first cutting wheel 420 can reduce the resistance during cutting, so that the blade can penetrate the can lid more easily, thereby reducing the risk of the can lid being jammed or stuck, avoiding the jamming during cutting, and simultaneously, better guiding the can lid, making it easier to be accurately cut during cutting, and improving the cutting efficiency.
In some embodiments of the present invention, a blocking structure is provided on the housing 100, the blocking structure being located at one side of the eccentric 500, the blocking structure being abutted against the first elastic member 511 to maintain the eccentric 500 in a stationary state during the sliding with the idler 600.
As shown in fig. 4, a blocking structure is disposed on the housing 100, and the blocking structure is located at the rear side of the eccentric wheel 500, and in the can-opening cutting state, the idle wheel 600 drives the eccentric wheel 500 to rotate clockwise, the eccentric wheel 500 is driven by the idle wheel 600, the first elastic member 511 at the end of the gear tooth segment 510 rotates to be against the blocking structure, and simultaneously, the eccentric wheel 500 and the idle wheel 600 slip, and the speed of the idle wheel 600 slipping is far greater than the running speed of the driving wheel 410, so that a stable rigid gap is formed between the first cutting wheel 420 and the second cutting wheel 520.
In some embodiments of the present invention, the first resilient member 511 is a compression spring.
In some embodiments of the invention, the axial direction of the compression spring is tangential to the edge of the eccentric 500.
As shown in fig. 2 and 4, the first elastic member 511 is a compression spring that is axially tangential to the edge of the eccentric 500, and in the feeding state, the idle wheel 600 drives the eccentric 500 to rotate clockwise, so that the compression spring can directly abut against the blocking structure along the rotation path of the outer edge of the eccentric 500 until the idle wheel 600 and the eccentric 500 slip. In the retracting state, the compression spring releases the elastic force, the eccentric wheel 500 rotates counterclockwise and engages with the idle wheel 600, and the second cutting wheel 520 is pulled out of the gap with the first cutting wheel 420 by the driving of the eccentric wheel 500, thereby completing the retracting action. It should be noted that, when the eccentric wheel 500 rotates counterclockwise to a designated position, the eccentric wheel will automatically stop, specifically, the position of the eccentric wheel 500 can be detected by a limit switch installed in the housing 100, and a stop signal is triggered when the designated position is reached, so that the eccentric wheel 500 stops rotating, or a position sensor is used to monitor the rotation position of the eccentric wheel 500, and when the preset position is reached, the sensor will send a signal to the control system to instruct the eccentric wheel 500 to stop rotating.
In some embodiments of the present invention, the transmission 300 is a reduction gear set.
In some embodiments of the present invention, the reduction gear set includes a primary gear 310, a secondary gear 320 and a tertiary gear 330 sequentially meshed, the primary gear 310 being in driving connection with the drive mechanism 200, the tertiary gear 330 being in driving connection with a drive wheel 410.

In some embodiments of the present invention, the spindle 400 is provided with a second elastic member 430, the second elastic member 430 is located between the driving wheel 410 and the spindle 400, and the second elastic member 430 is used to fix the position of the driving wheel 410 on the spindle 400.
As shown in fig. 1, in this embodiment, the second elastic member 430 is a snap spring, the main shaft 400 is provided with a limit groove corresponding to the snap spring, the snap spring is embedded in the limit groove, and the lower end of the snap spring abuts against the driving wheel 410, so that the driving wheel 410 is fixed at a specific position on the main shaft 400, the driving wheel 410 is prevented from being offset or loose during operation, and the effects of buffering and damping are achieved, so that instability and loss caused by vibration are reduced.

As shown in fig. 2 to 3, when the cutting is completed, the motor is reversed, and the compression spring releases the elastic force to push the eccentric wheel 500 to rotate counterclockwise, the gear tooth segment 510 on the eccentric wheel 500 is engaged with the driven gear 620 to rotate, the eccentric wheel 500 rotates counterclockwise under the rotation of the driving mechanism, the eccentric wheel 500 is reversed to drive the sliding plate 700 to move leftwards through the double ring plate 710, the second cutting wheel 520 is far away from the first cutting wheel 420, and then the automatic can opener is removed from the can edge, so that the retracting action is completed.
Therefore, under the drive of the motor, the primary gear 310, the secondary gear 320 and the tertiary gear 330 are transmitted step by step to drive the driving wheel 410 to rotate, the driving wheel 410 is meshed with the driving gear 610 and drives the driven gear 620 to rotate, so as to drive the driven gear 620 to drive the eccentric wheel 500 to rotate synchronously, the eccentric wheel 500 pulls the slide plate 700 to enable the second cutting wheel 520 to move towards the direction close to the first cutting wheel 420, when the eccentric wheel 500 rotates until the end of the gear tooth section 510 abuts against the driven gear 620, the driven gear 620 slides against the eccentric wheel 500, the eccentric wheel 500 is kept stationary under the action of the first elastic piece 511 abutting against the shell 100, the first cutting wheel 420 and the second cutting wheel 520 keep clamped on the can edge, and therefore, during the cutting process, the driving wheel 410 can drive the first cutting wheel 420 and the second cutting wheel 520 to complete the actions of feeding and retracting, and simultaneously enable the first cutting wheel 420 and the second cutting wheel 520 to form a stable rigid gap, so that the can edge can be clamped effectively, and the stability and reliability of cutting action are improved.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
