DETAILED DESCRIPTION

[0048] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figure 1 to Figure 5 As shown, this embodiment proposes

[0050] A dry powder rotary packaging machine comprises a frame 1 and a material rotary drum 2 rotatably arranged on the frame 1, wherein the material rotary drum 2 has a discharge port 3, and further comprises

[0051] The pressure bin 4 is arranged below the material rotary drum 2 and is connected to the discharge port 3.

[0052] The discharge cylinder 5 is arranged on the pressure chamber 4 and communicated with the pressure chamber 4.

[0053] The lifting airbag 6 is located in the pressure chamber 4, and one end of the lifting airbag 6 is arranged on the inner wall of the pressure chamber 4.

[0054] The bell 7 is conical, with its top end inserted into the discharge port 3, and is arranged at the movable end of the lifting airbag 6. After the lifting airbag 6 is inflated and deflated, it drives the bell 7 to rise and fall, and closes or opens the discharge port 3.

[0055] In this embodiment, the dry mortar is manually bagged one by one, which is time-consuming. The dry mortar passes through the material rotary drum 2 and enters the pressure bin 4. The material in the pressure bin 4 then enters the discharge drum 5 for discharging and bagging. Since the material rotary drum 2 can be provided with multiple workstations, the processing efficiency is high and there is no need to wait for each process. However, this operation requires the discharge drum 5 to discharge the material intermittently, and the mixed dry mortar is temporarily stored in the material rotary drum 2. The discharge port 3 of the material rotary drum 2 is connected to the pressure bin 4. The lifting airbag 6 is provided in the pressure bin 4 to drive the material bell 7 to rise and fall, so as to control the opening and closing of the discharge port 3. The material bell 7 is conical, and the conical shape has the effect of preventing segregation, and the top of the cone just blocks the discharge port 3.

[0056] Further, the discharge barrel 5 includes

[0057] The square diameter reducing cylinder 8 has a circular end surface connected to the pressure chamber 4.

[0058] The material discharging shell 9, the square end surface of the square diameter reducing cylinder 8 is connected to the material discharging shell 9, the material discharging shell 9 is provided with a material discharging channel 10, and the material discharging channel 10 has an air inlet 11,

[0059] The air charging box 12 is arranged on the discharge housing 9 and is communicated with the air inlet 11 .

[0060] In this embodiment, the dry mortar entering the pressure bin 4 from the discharge port 3 is connected to the discharge shell 9 through the square and round reducer 8. A plurality of air inlets 11 are arranged on the bottom or side of the discharge shell 9. The gas charging box 12 is connected to the air inlet 11. Gas can be charged through the air inlet 11 to blow the dry mortar out from the discharge channel 10. Since the lifting airbag 6 can control the material bell 7 to block the discharge port 3 of the material rotary drum 2, it is equivalent to that there is only one outlet of the discharge channel 10 in the connecting space between the discharge shell 9 and the square and round reducer 8. When the gas charging box 12 blows gas from the air inlet 11, the dry mortar is blown out from the only outlet for packaging. This packaging machine utilizes the gas pressure sprayed out by the inflation box 12 which is higher than the normal pressure, and can replace the impeller as the power source for material filling, and pulse air supply is used to spray the dry powder mortar material in the pressure bin 4 into the packaging bag. When the material rotary drum 2 has multiple stations, it can also be used together, thus solving the problem of low bagging efficiency when the dry powder rotary packaging machine in the prior art packages the dry powder mortar.

[0061] Furthermore, it also includes

[0062] The air bag 13 is arranged below the material rotary drum 2 and rotates with the material rotary drum 2. The pressure chamber 4 is fixed on the air bag 13.

[0073] In this embodiment, the weighing frame 19 is arranged at the position of the discharge port 3 of the discharge shell 9, and the purpose is to weigh the packaged material bags. When the weighed material bags reach the preset weight, it proves that the bagging is completed. The corrugation sensor 18 on the weighing frame 19 feeds back a signal to the cylinder 16, and the cylinder 16 drives the gate 17 to close the discharge channel 10.

[0074] Furthermore, it also includes

[0075] The pneumatic bell valve 20 is arranged on the pressure chamber 4 and is used to control the inflation or deflation of the lifting airbag 6.

[0077] In this embodiment, there is also a material level sensor 21 in the pressure bin 4. When the dry mortar in the pressure bin 4 reaches the position of the material level sensor 21, it proves that the dry powder is sufficient. At this time, the material level sensor 21 transmits a signal to the pneumatic bell valve 20, and the pneumatic bell valve 20 controls the inflation of the lifting airbag 6, driving the bell 7 to close the discharge port 3. The overall working sequence is that after the cylinder 16 drives the gate 17 to close, the pneumatic bell valve 20 drives the bell 7 to descend, and the dry mortar falls into the pressure bin 4 until the height of the dry mortar reaches the material level. The pneumatic bell valve 20 inflates the lifting airbag 6, drives the bell 7 to rise, and closes the feed port. After receiving the signal, the cylinder 16 drives the gate 17 to rise and open the discharge channel 10. At the same time, the air box 12 supplies air in a pulsed manner, and the dry mortar is sprayed out. After reaching the set weight of the weighing frame 19, the gate 17 is closed, the filling is completed, and then a new cycle is entered.
