DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 to Figure 2 As shown, the embodiment of the utility model proposes a packaging bag supporting device for bagging calcium carbonate powder, which is used to unfold the packaging bag and fix the position of the packaging bag during the process of bagging calcium carbonate powder, so that the opening of the packaging bag remains open, so as to facilitate pouring the calcium carbonate powder into the packaging bag.

[0025] Please refer to Figure 1 and Figure 2 The packaging bag supporting device for bagging calcium carbonate powder comprises a frame 1, on which a plurality of vertical support rods 11 are arranged, and a support ring 12 is arranged at the top of the support rod 11, and the support ring 12 is used to support the packaging bag; the frame 1 is also provided with a movable plate 2 which can be lifted and lowered in the vertical direction and a first driving component 3 which is transmission-connected with the movable plate 2, the movable plate 2 is located directly above the support ring 12, and the first driving component 3 is used to drive the movable plate 2 to approach or move away from the support ring 12, the movable plate 2 is provided with a plurality of slide grooves 21 at intervals along the circumference of the support ring 12, and the length directions of the slide grooves 21 are respectively parallel to the radial direction of the support ring 12, and movable movable rods 4 are respectively arranged in the slide grooves 21, and the movable movable rods 4 are respectively arranged in the slide grooves 21, and the movable movable rods 4 are respectively arranged in the slide grooves 21. One end of the rod 4 extends toward the direction close to the support ring 12 and the end of the movable rod 4 close to the support ring 12 is respectively provided with a wedge block 41, and the wedge block 41 is aligned one by one with the support rod 11. The movable plate 2 is also provided with a rotatable rotating disk 5 and a second driving component 6 which is transmission-connected with the rotating disk 5. The rotating disk 5 is provided with a guide groove 51 which is connected one by one with the slide groove 21 and the movable rod 4 extends into the corresponding guide groove 51 respectively. The second driving component 6 is used to drive the rotating disk 5 to rotate and to abut against the movable rod 4 through the inner wall of the guide groove 51 to push the movable rod 4 to move in the slide groove 21, and to drive the wedge block 41 to approach or move away from the support rod 11 through the movable rod 4.

[0026] Specifically, the operating steps of carrying out the calcium carbonate powder bagging operation using the packaging bag support device for calcium carbonate powder bagging provided in this embodiment are as follows: first, the packaging bag is placed in the area surrounded by the support ring 12, the first driving component 3 drives the movable plate 2 to descend so that the wedge block 41 extends into the packaging bag, and then the second driving component 6 drives the rotating disk 5 to rotate. When the rotating disk 5 rotates, the inner wall of the guide groove 51 abuts against the movable rod 4 and pushes the movable rod 4 to move in the slide groove 21, so that the wedge block 41 moves in the direction close to the support rod 11 under the drive of the movable rod 4.
