[0015] like Figure 1-4 As shown, this embodiment provides a bag pre-coating device, including a fixed sleeve 1 with a diameter of 400mm and a length of 5m, a detachable rotating mechanism is installed in the fixed sleeve 1, the rotating mechanism includes two circular plates 4 with a diameter of 350mm, a rotating shaft 7 is installed in the center of the two circular plates 4, the rotating shaft 7 is fixedly connected to the circular plates 4, one end of the rotating shaft 7 extends outward and is connected to a driving mechanism, four through holes 6 with a diameter of 100mm are respectively provided at corresponding positions on the two circular plates 4, each through hole 6 is used to install a bag, and the two ends of the bag are respectively connected to the two circular plates 4; a plurality of guide wheels 5 are installed on the outer side of the circular plate 4, and the guide wheels 5 are in contact with the inner wall of the fixed sleeve 1.

[0016] Preferably, a driven pulley 8 is provided at one end of the rotating shaft 7 that extends out, and the driving mechanism includes a driving motor 12 and a reducer 11, and a driving belt 9 is provided at the output end of the reducer 11, and a belt 9 is provided between the driving belt 9 and the driven pulley 8, and a belt connection method is adopted to make it easy to separate the rotating shaft from the driving mechanism, so as to facilitate the installation of the rotating mechanism into the fixed sleeve 1 or removal from the fixed sleeve 1.

[0017] Preferably, a plurality of windows 3 are provided at the top of the outer wall of the fixed sleeve 1, each window 3 is provided with a switchable door, and the window 3 is used for adding lime powder.

[0018] Preferably, a support seat 2 is provided at the bottom end of the fixed sleeve 1 .

[0019] Preferably, the guide wheels 5 are installed on the outer side of the circular plate 4 near the circumferential surface, and a central shaft is installed at the center of each guide wheel 5. One end of the central shaft is fixedly connected to the circular plate 4, and the other end is equipped with the guide wheel 5 through a bearing.

[0020] The working principle of the utility model is as follows: first, the rotating mechanism is taken out from the fixed sleeve 1, and then the four cloth bags that need to be pre-coated are installed in the through holes 6 between the two circular plates 4, and the two ends of the cloth bags are clamped and fixed with the corresponding through holes 6, and then the entire rotating mechanism carrying the cloth bags are inserted into the fixed sleeve 1 along the axial direction, so that the fixed sleeve 1 wraps the circular plates 4 at both ends, and then the window 3 on the top of the fixed sleeve 1 is opened, a certain amount of quicklime powder is added into the fixed sleeve 1, and then the window 3 is closed, and the pneumatic drive motor 12 is driven by the driving motor 12 to rotate the rotating shaft 7, and the rotating shaft 7 drives the two circular plates 4 to rotate together, and the two circular plates 4 drive all the cloth bags to rotate with the rotating shaft 7 as the axis. During the rotation process, the outer surface of the cloth bag will adhere to the quicklime powder and lift the quicklime powder in the space of the fixed sleeve 1. After the motor rotates for a period of time, all the cloth bags will complete the quicklime pre-coating work, and finally the rotating mechanism is pulled out as a whole, and each cloth bag is taken down and installed in the bag dust collector.
