As shown in fig. 14 and 17, specifically, in this embodiment, a bend 36 is provided at the end of the stainless steel strip-shaped sheet 34, a wedge-shaped protrusion 19 matching the shape of the bend 36 is provided on the mounting plate 10, and an outer wall of the bend 36 is in interference fit with an outer wall of the wedge-shaped protrusion 19, so that one end of the stainless steel strip-shaped sheet 34 is fixedly connected to the mounting plate 10 by a profile fit.

An annular boss of the driving gear ring 22 is provided with a slot 24 matched with the shape of the bend 33, the outer wall of the bend 33 is in interference fit with the inner wall of the slot 24, and the other end of the stainless steel strip-shaped sheet 34 is fixedly connected with the driving gear ring 22 in a profile fit manner.

In the utility model, the resetting method of the garbage bag packaging mechanism can also adopt the method commonly used in the prior art, for example; the control device comprises a timer or a programmed time interval, and when the reset time is reached, the control device controls the motor to stop rotating to finish the closing reset action.

The utility model discloses a when the disposal bag baling mechanism moves, can adopt following mode to go on: the control device controls a motor of the driving device to rotate forwards, the motor drives the reduction transmission gear 21 to rotate so as to drive the driving gear ring 22 to rotate, the driving gear ring 22 drives one end of the stainless steel strip-shaped sheet 34 to move around the through hole 11 of the mounting plate, and the bag opening of the garbage bag is shrunk and concentrated onto the sealing device 40; when the triggering structure 26 on the driving gear ring 22 triggers the closing-in end position detection device 15, the control device controls the heating wire 42 in the sealing device 40 to heat according to the sensor information of the closing-in end position detection device 15 to realize the sealing and packaging operation; after sealing the packing operation and accomplishing, the motor reversal drives drive ring gear 22 reversal, drive ring gear 22 drives stainless steel banding thin slice 34's one end is followed mounting panel through-hole 11 reverse migration, until reset boss 23 on the drive ring gear 22 with spacing boss 18 contact on the mounting panel 10, drive ring gear 22 can't continue to rotate, and the motor stalls, and the electric current increases to send feedback information to controlling means, controlling means accomplishes the action of closing up and resetting according to feedback information control motor stall.

The present invention has been described in detail with reference to the specific embodiments, but the present invention is only by way of example and is not limited to the specific embodiments described above. Any equivalent modifications and substitutions to those skilled in the art are intended to be within the scope of the present invention. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
