[0037] The first component feed assembly 20 is connected to the first feed port 11, and is used to deliver the first component into the mixing tank 10. Specifically, the first component feed assembly 20 includes a first component container 21 and a first feed pump 22. The first component container 21 is sealedly connected to the first feed port 11 through a pipeline with the first feed pump 22. The switch solenoid valve of the first feed pump 22 is connected to the program controller signal.

[0038] The second component feed assembly 30 is connected to the second feed port 12, and is used to deliver the second component into the mixing tank 10. Specifically, the second component feed assembly 30 includes a second component container 31, a second feed pump 32, and a second component transfer tank 33. The second component container 31 is connected to the second component transfer tank 33 through a pipeline with the second feed pump 32, and the discharge port at the bottom of the second component transfer tank 33 is connected to the second feed port 12, and is sealed by the sealing cover. The switch solenoid valve of the second feed pump 32 is connected to the program controller signal.

[0039] A nitrogen purge connection port 14 is also provided on the top cover of the mixing tank 10 on one side of the first feed port and the second feed port. The nitrogen purge assembly 60 is connected to the nitrogen purge connection port 14 to discharge the epoxy putty obtained by mixing the first component and the second component from the discharge port 13 of the mixing tank 10 under nitrogen gas pressure, thereby accelerating the discharge speed and improving production efficiency.

[0040] Specifically, the nitrogen purge assembly 60 includes a nitrogen cylinder 61 , and the nitrogen cylinder 61 is connected to the nitrogen purge connection port 14 through a pipeline with a nitrogen switch valve 62 , and the nitrogen switch valve 62 is connected to the program controller signal.

The bottom end of the second component transfer tank 33 is mounted on a support plate 34 through a bracket, and the support plate 34 is provided with a second weighing device 35, and the second weighing device 35 is connected to the program controller signal, and is used to measure the weight of the second component transfer tank 33 in real time and send it to the program controller in the form of a signal.

[0052] The mixing device further includes a stirring shaft 71, a stirring blade 72 and a stirring motor 73.

[0055] The feeding process of the first component is:

[0056] When the first feed pump 22 is turned on, the first component is transported from the first component container 21 to the mixing tank 10, and at the same time, the first weighing device 50 transmits the measured weight of the mixing tank 10 to the program controller in real time. When the program controller receives that the difference between the weight of the mixing tank 10 and the weight before the first component is fed is equal to the set first component feed amount, the first feed pump 22 is controlled to be turned off to stop transporting the first component.

[0057] The feeding of the second component can be before the feeding of the first component or after the feeding of the first component. The specific operation is: when the second feeding pump 22 is turned on, the second component enters the second component transfer tank 33 from the second component container 31, and at the same time, the second weighing device 35 transmits the measured weight of the second component transfer tank 33 to the program controller in real time. When the program controller receives that the difference between the weight of the second component transfer tank and the weight before the second component is fed is equal to the set second component feed amount, the development valve of the second feeding pump is controlled to close, the feeding of the second component is stopped, and the first electromagnetic switch valve 331 is controlled to open, so that the second component flows into the mixing tank 10 through the cone mouth.

[0058] The program controller starts the stirring motor 73 to drive the stirring shaft to rotate, mix the first component and the second component evenly in the mixing tank, and then open the discharge switch valve 131 and the nitrogen switch valve 62 to discharge the epoxy putty in the mixing tank from the discharge port 13 with the assistance of nitrogen. After all the materials are discharged, the next batch of materials are fed, mixed, and discharged, and the cycle continues.

[0059] The nitrogen purge assembly 60 is used to introduce nitrogen into the mixing tank 10, which can speed up the discharging speed and remove the residual putty, thereby achieving the cleaning effect in the tank body. After all the materials are discharged, the next batch of materials are fed, mixed and discharged, and the cycle is repeated.
