[0013] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model are described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed base body implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] The specific embodiments of the utility model are further described in detail below in combination with the drawings.

[0016] By Figs. 1 to 4 It is given, including the blanking pipe 1 of upper and lower axial, the outer edge surface of blanking pipe 1 is fixed with multiple guide columns 2 along the circumferential direction of it, the expansion plate 3 is slidably connected on guide column 2, the push plate 4 of L shape is fixed on the upper end of expansion plate 3, the annular block 5 that can move up and down is arranged on blanking pipe 1 coaxially and is located above expansion plate 3, the upper end of expansion plate 3 is hingedly connected with annular block 5 through swing bar 6.

[0017] In order to make annular block 5 move up and down, the annular block 5 is slidably connected with blanking pipe 1, and the stud 7 that can rotate is arranged on the rear end of blanking pipe 1 and is threadedly connected with annular block 5.

[0018] In order to make stud 7 rotate, the motor 8 is arranged on the rear end of blanking pipe 1 and is located above stud 7, and the output shaft of motor 8 is coaxially fixedly connected with stud 7.

[0019] In order to facilitate the reset of expansion plate 3, the baffle 9 is arranged on the free end of guide column 2, and the compression spring 10 is sleeved on guide column 2 and is located between baffle 9 and expansion plate 3.

[0020] In order to facilitate the increase in fixed effect, the expansion plate 3 outer surface is provided with a plurality of anti-skid strips 11.

[0021] The utility model discloses when using, first with the unloading machine outlet fixed connection of the unloading pipe 1 upper end, then when needing to fill, the operator opens the motor 8, and the motor 8 drives the stud 7 rotation, and then drives the annular block 5 to move downward, and the annular block 5 presses the swing lever 6 to make multiple swing lever 6 swing simultaneously, and then drives multiple expansion plate 3 to move outward simultaneously through the push board 4, and multiple expansion plate 3 also extrude the compression spring 10 outward while moving outward on the guide column 2, and after moving a distance outward, the outer surface of multiple expansion plate 3 contacts the inner surface of the flour bag and realizes the expansion fixing of the flour bag, and the flour bag opening is expanded to a circle, and the unloading pipe 1 is located at the central position of the opening at this time.
