Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguisher processing equipment, and particularly relates to a fully automatic and high-precision dry powder filling equipment for fire extinguishers. Background Art

[0002] The dry powder filling of the fire extinguisher tank needs to go through two fillings. First, rough filling is carried out, and then fine filling is carried out after rough filling. During rough filling, the operator manually transports the tank to the rough filling weighing device for weighing, then fills it through a filling machine, and then reweighs it. After the filling is qualified, it is transported for fine filling. The above process not only has a large workload, but also has low filling efficiency. At the same time, during rough filling, the material enters from the feed pipe, is transported through the conveying pipe to the rough filling nozzle, and the rough filling nozzle fills the material into the tank. However, there are also requirements for the filling weight during rough filling. During rough filling, it is often overfilled or underfilled, which affects the subsequent fine filling efficiency. The rough filling cannot meet the filling requirements, and at the same time, the fine filling cannot reach the required filling standard. Moreover, the current dry powder filling equipment for fire extinguishers cannot be applied to fire extinguishers of different specifications and sizes for filling, cannot meet the new national standard requirements for dry powder filling of fire extinguishers, and cannot meet the production line requirements.

It should be noted that the servo motor 1202 works to drive the spiral blade to rotate for precise filling and powder supplement. Cooperating with the weighing sensor to achieve the required precise filling. The drive motor works to drive the rotary stirring knife to prevent the dry powder inside the powder storage cylinder 1201 from accumulating and caking, which affects the normal powder supplement of the spiral blade and avoids affecting the powder supplement accuracy. The above structure is similar to the screw metering working principle of the existing powder filling machine. An air extraction pipe is arranged beside the outlet of the powder storage cylinder 1201. The air extraction pipe is used to suck a small amount of dry powder ejected from the fire extinguisher bottle during the filling process to avoid long-term accumulation and affect its working environment.

[0037] Specifically, the lifting drive assembly 14 includes a servo motor 1404. The servo motor 1404 is disposed on the frame 7. A lead screw is provided at the output end of the servo motor 1404.

The chain is disposed on a sprocket, and the sprocket is disposed on the frame 7. It should be noted that when the servo motor 1404 operates, the lead screw rotates to drive the transmission seat and the support seat 1401 to move up and down, so as to adjust the working position of the precision filling assembly 12, and at the same time cooperate with the counterweight 1403 to ensure the stability of the precision filling assembly 12 after moving to the required position.

[0038] The working principle of this specific embodiment is as follows: First, the empty fire extinguishers are transported to the material blocking cylinder 101 by the fire extinguisher feeding conveyor belt 8. The material blocking cylinder 101 works in cooperation with the sensor to make the fire extinguishers enter the required workstations one by one at intervals. The push rod cylinder 105 works in cooperation with the mounting seat, the auxiliary slide rail, and the mounting plate 102 to adjust the working position of the fire extinguisher positioning push block 103, so as to push the fire extinguisher onto the lifting plate 604; at this time, the weighing sensor works to tare and weigh the fire extinguisher bottle.

[0039] Then the lifting cylinder works to drive the lifting plate 604 to rise, so that the mouth of the fire extinguisher bottle is abutted against the rough filling head 602. At this time, the vacuum tube clamp valve 501 on the vacuum tube is opened to evacuate the fire extinguisher bottle. After the evacuation is completed, the vacuum tube clamp valve 501 is closed, and then the first ball valve 503 is opened to perform rough filling. The rough filling process will work in cooperation with the weighing sensor to reach the required rough filling weight. When the rough filling is completed, the first ball valve 503 is closed to close the filling pipe. The vacuum tube cooperates with the vacuum tube clamp valve 501 to open to suck the dry powder that has not fallen at the end of the filling pipe into the vacuum bucket 3, avoiding the scattering of excess dry powder when the fire extinguisher is separated from the rough filling head 602. A filter element is provided in the vacuum bucket 3 to filter the dry powder for subsequent collection of the dry powder. Then the vacuum tube clamp valve 501 is closed, and the air injection pipe cooperates with the air injection valve 504 to open. At this time, the internal vacuum state of the fire extinguisher is cancelled and it is separated from the rough filling head 602.

[0040] Then the lifting cylinder resets to lower the lifting plate 604. At the same time, the first cylinder 1104 and the second cylinder 1106 work to move the clamping jaws 1102 to both ends of the fire extinguisher, and the fire extinguisher is clamped by the clamping jaw cylinder 1101. Then the first cylinder 1104 and the second cylinder 1106 reset to drive the fire extinguisher that has completed rough filling to the fire extinguisher bottle discharging conveyor belt 9.

[0041] The fire extinguisher bottle discharging conveyor belt 9 conveys the fire extinguishers that have been roughly filled to between the clamping blocks 1304. The clamping cylinder 1303 operates to make the clamping blocks 1304 clamp the fire extinguishers. Subsequently, the auxiliary lifting cylinder 1301 operates to drive the support frame 1302 to rise, so that the fire extinguishers are separated from the fire extinguisher bottle discharging conveyor belt 9, and then the fire extinguishers rise for precise filling. Before precise filling, it works in cooperation with the weighing sensor to calculate the required precise filling weight; when the fire extinguishers between the clamping blocks 1304 move accordingly, multiple fire extinguishers will rise and fall synchronously, avoiding the vibration caused by the individual movement of multiple fire extinguishers, which affects the value of the weighing sensor and ultimately affects the filling accuracy.

[0042] During precise filling, the servo motor 1202 operates to rotate the spiral blade, and at the same time the drive motor operates to drive the rotating stirring knife to rotate on the inner wall of the powder storage cylinder 1201. The powder outlet of the powder storage cylinder 1201 discharges powder for precise filling. When the powder needs to be replenished in the powder storage cylinder 1201, the pipe clamp valve 1203 and the second ball valve 1205 are closed, and the auxiliary vacuum pipe clamp valve 1206 is opened to make the auxiliary vacuum barrel 1204 vacuumize. After the vacuumizing is completed, the auxiliary vacuum pipe clamp valve 1206 is closed, and then the second ball valve 1205 is opened to draw the dry powder into the auxiliary vacuum barrel 1204. When the auxiliary vacuum barrel 1204 is full of dry powder, the second ball valve 1205 is closed, and the blowing valve on the auxiliary vacuum barrel 1204 is opened. At the same time, the pipe clamp valve 1203 is opened to make the dry powder fall into the powder storage cylinder 1201 to achieve the powder replenishment effect.

[0043] When the precise filling is completed, it works in cooperation with the weighing sensor to reach the required precise filling weight. The auxiliary lifting cylinder 1301 operates to reset, so that the filled fire extinguishers return to the fire extinguisher bottle discharging conveyor belt 9. The clamping cylinder 1303 operates to make the clamping blocks 1304 separate from the fire extinguishers, and the fire extinguishers enter the next processing station.

[0044] The present invention is not limited to the foregoing specific embodiments. The present invention extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
