The following detailed description of the steps of using a cash register with an automatic packing function in this document is provided with reference to fig. 1 to 5:

at the beginning, the resisting rod 18 is at the limit position close to one side of the symmetry center, the pressure sensor 19 is against the adjacent baffle 16, the lower end of the baffle 16 is turned to the shopping basket placing cavity 13, the first lifting block 24 is at the upper limit position under the action of the first spring 25, the slide block 28 is at the limit position close to one side of the symmetry center under the action of the second spring 30, one end of the slide block 28 close to the symmetry center extends into the stockpiling cavity 14, the hinge telescopic rod 42 is in the extension state, the lifting platform 39 is at the upper limit position, the upper end face of the lifting platform and the lower wall of the film laying cavity 51 are located in the same plane, and the second lifting block 71 and the cutter 72 are at the upper limit position.

When the shopping basket is in operation, the shopping basket is placed in the shopping basket placing cavity 13, the baffle 16 prevents the shopping basket from sliding downwards, when commodities in the shopping basket are taken out, the pressure borne by the pressure sensor 19 enters a set empty shopping basket pressure range, the pressure sensor 19 starts the first motor 21, the first motor 21 is started to drive the first screw rod 22 to rotate, the abutting rod 18 and the pressure sensor 19 are driven to move towards one side far away from the symmetry center through threaded connection, the abutting rod 18 and the pressure sensor 19 are received in the abutting rod cavity 17, the lower end of the baffle 16 is turned back into the turning cavity 15, the shopping basket slides downwards to abut against the upper end of the sliding block 28, under the dead weight pressure of the shopping basket, the first spring 25 contracts, the first lifting block 24 and the sliding block 28 slide downwards, when the sliding block 28 slides to abut against the inclined surface of the inclined surface block 32 or abut against the upper end of the shopping basket, the sliding block 28 slides towards the direction far away from the symmetry center, and when the sliding block 28 slides to be separated from the shopping basket, the first lifting block 24 and the second spring When the length of the plastic film in the film laying cavity 51 is enough, the cam 78 rotates half a circle, the push rod 75 slides down to the lower limit position, the cutter 72 cuts off the plastic film, at this time, the fourth motor 68 stops, the commodity is pushed into the sliding groove 33, the second motor 35 is started to drive the second screw rod 36 to rotate, and then the threaded sleeve 37 is driven to slide through threaded connection, and then the hinge telescopic rod 42 contracts to drive the lifting platform 39 to slide downwards, and then commodities press the center of the plastic film downwards into the packaging cavity 34, the third motor 48 is started to drive the fan 49 to rotate for air supply, the air is blown to the hot air port 44 through the air supply channel 50, the heating wire 45 is electrified, the air is heated by the heating wire 45 and then melts and seals the upper end of the plastic film, the second motor 35 rotates reversely to drive the hinge telescopic rod 42 to extend after packaging is completed, the lifting platform 39 rises and returns to the initial state, after packaged commodities are taken away, the fourth motor 68 is started to carry out next film feeding.

The invention has the beneficial effects that: the shopping basket stacking device can automatically recycle and stack empty shopping baskets into a stack, reduces the working content and the working strength of workers, can automatically pack and bag commodities after the payment of the commodities is finished, reduces the time of guests staying at a cash register after the payment is finished, greatly accelerates the working efficiency of the cash register, reduces the congestion degree in front of the cash register, and shortens the time of queuing.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
