Technical Field

[0001] The invention relates to the technical field of intelligent trash can manufacturing, in particular to a bagging tool for a garbage bag box used in the intelligent trash can. Background Art

[0002] Smart trash cans for home or office use are what people usually call induction trash cans. Their lids can be opened and closed by sensors, without manual or foot movements. This smart trash can will be equipped with a trash bag box with a long trash bag. The trash bag is used in sections. After one section of the trash bag is used, the smart trash can can automatically seal and cut it and then pull out another section for use. After the trash bag is unfolded, it is a thinner and soft tube shape. The raw material of this trash bag is folded into a flat body and then wound into a whole roll. The bag box and trash bag are installed in the factory and used as consumables.

[0003] This common garbage bag box is as follows Figure 1 , Attachment Figure 2 As shown, the garbage bag box 20 includes a bottom box 2a, a cover body 2b and a garbage bag 30. A middle through hole 21a is provided in the middle of the bottom box 2a. The bottom box 2a is provided with a circle of receiving grooves 22a for receiving the garbage bag 30 around the middle through hole 21a. The cover body 2b is snapped onto the bottom box 2a and covers the receiving grooves 22a. A circle of notches 20c connecting the receiving grooves 22a is also provided between the cover body 2b and the bottom box 2a. The garbage bag 30 is pulled out from the notch 20c and the end is heat-sealed.

[0004] The garbage bag in this type of garbage bag box installed in the bottom box receiving groove is relatively long. Since the garbage bag body is thin and soft and difficult to shape, it is difficult and inefficient to manually load the garbage bag into the bottom box receiving groove, and it is often difficult for one person to complete it. For this reason, the applicant disclosed a Chinese invention patent with patent number ZL201922004214.7 on September 11, 2020, entitled "A simple bagging tooling for a garbage box of a smart trash can", which includes a circumferential anti-rotation positioning member and an axial pressure member. The circumferential anti-rotation positioning member includes a horizontally arranged positioning plate, and the positioning plate is arranged to be a square that matches the square inner hole of the garbage box; the lower end of the axial pressure member has a cavity with an opening facing downward, and the axial positioning member is sleeved on the circumferential anti-rotation positioning member, and the axial pressure member presses the garbage box to prevent the garbage box from axial movement. The bagging tool can prevent the garbage box from rotating in the circumferential direction by putting the garbage box on the positioning plate, and the axial pressing piece presses the garbage box to prevent it from moving axially, thereby realizing the positioning of the garbage box, eliminating one person for assistance and realizing single-person operation. Straightening the garbage bag with the help of the axial pressing piece can prevent the garbage bag from becoming fluffy and bouncing during the bagging process, reduce repeated operations, and improve efficiency. However, when using this simple tool, during the bagging process, the bag body of the garbage bag is still difficult to fit with the outer peripheral surface of the axial pressing piece, and the garbage bag is difficult to shift smoothly, and the bagging efficiency needs to be improved.
