Both the air inlet pipe 4 and the discharge pipe 7 are fixedly connected to the cover plate 3 through a seal 10. A chute 11 is opened on the right side of the inner cavity of the material storage barrel 1. A slider 12 is slidably connected inside the chute 11. A traction plate 13 is fixedly installed on the left side of the slider 12. The left side of the traction plate 13 is fixedly connected to the right side of the sleeve 9. A threaded cylinder 14 is rotatably connected to the right side of the top of the cover plate 3 through an opening. A first threaded rod 15 is threadedly connected inside the threaded cylinder 14. A plug rod 16 is fixedly installed at the rear of the first threaded rod 15. The rear of the plug rod 16 penetrates through the traction plate 13 and extends to the outside of the traction plate 13. By providing the air inlet pipe 4 and connecting the left end of the air inlet pipe 4 to an air compressor, within an appropriate range of the air inlet pipe 4, the control valve 5 and the pressure gauge 6 are installed to facilitate controlling the pressure and adjusting the pressure of the liquid material in the material storage barrel 1. Then, by opening the discharge control valve 8 on the surface of the discharge pipe 7, the liquid in the material storage barrel 1 can be discharged to the outside of the material storage barrel 1 through the sleeve 9 and the discharge pipe 7, which can not only achieve the effect of saving labor, but also achieve the effect of controlling the discharge amount by providing the discharge pipe 7. During the discharging process, the threaded cylinder 14 can be rotated to make the threaded cylinder 14 drive the first threaded rod 15 to extend. The extension of the first threaded rod 15 drives the plug rod 16 to descend. The descent of the plug rod 16 drives the traction plate 13 to descend. The descent of the traction plate 13 drives the sleeve 9 to descend. After the sleeve 9 descends, the liquid at the bottom of the inner cavity of the material storage barrel 1 can be pumped out, reducing the raw material residue and effectively meeting the discharge amount requirement.

Then, by opening the discharging control valve 8 on the surface of the discharging pipe 7, the liquid in the storage barrel 1 can be discharged to the outside of the storage barrel 1 through the sleeve 9 and the discharging pipe 7. This can not only achieve the effect of saving labor, but also achieve the effect of controlling the discharging amount by setting the discharging pipe 7. During the discharging process, the threaded cylinder 14 can be rotated to make the threaded cylinder 14 drive the first threaded rod 15 to extend. The extension of the first threaded rod 15 drives the insertion rod 16 to descend. The descent of the insertion rod 16 drives the traction plate 13 to descend. The descent of the traction plate 13 drives the sleeve 9 to descend. After the sleeve 9 descends, the liquid at the bottom of the inner cavity of the storage barrel 1 can be pumped out, reducing the residue of raw materials and effectively meeting the requirement of the discharging amount. When it is necessary to clean the inside of the storage barrel 1, the second threaded rod 22 can be rotated to make the second threaded rod 22 drive the threaded sleeve 21 to rise. The rising of the threaded sleeve 21 drives the traction ring 17 and the arc plate 18 to rise. The rising of the arc plate 18 drives the pressing ring 19 to rise. The rising of the pressing ring 19 drives the sealing gasket 20 to rise. After the sealing gasket 20 rises, the cover plate 3 can be pulled upward. After the cover plate 3 rises, the cover plate 3 can be pulled forward, so that the insertion rod 16 moves to the outside of the traction plate 13, thereby achieving the effect of facilitating the cleaning of the inside of the storage barrel 1.
