Please refer to fig. 17 and 18. Step S5: the servo motor 4 drives the pressure head 6 to continuously move towards the workpiece 8 until the steel ball 16 is pressed into the workpiece 8, and the steel ball 16 is in interference fit with the workpiece 8, so that the workpiece 8 is sealed.
Please refer to fig. 19-21. Step S6: the servo motor 4 drives the pressure head 6 to ascend to the first sealing sleeve 14, the end part of the pressure head 6 is located between the first sealing ring 141 and the inner air passage 142, the raffinate control part 21 is opened, meanwhile, the outer positive pressure control part 22 is opened, and the outer positive air pressure enters the pressure head passage 17 through the inner air passage 142 via the air flow passage, so that pressure is generated on the filling flow passage, and therefore raffinate is extracted from the filling flow passage. Because the filling valve 1 has a compact structure, the joint of the positive pressure and the raffinate is very close to the product, and when high-speed flowing air passes through the joint, residual liquid is completely brought back under the action of the positive pressure and the negative pressure.
Please refer to fig. 22 and fig. 5. Step S7: after the raffinate is finished, the pressure head 6 rises to enable the steel ball inlet channel 161 to be communicated with the pressure head channel 17, the steel balls 16 enter the pressure head channel 17 and abut against the first ball plunger 131, and then the filling valve 1 resets.
According to the invention, the steel ball 16 is pushed into the workpiece 8 through the change of the position of the pressure head 6, and meanwhile, the vacuumizing, liquid filling and liquid extracting of the workpiece 8 are realized through the non-communication of the position of the pressure head 6, so that the whole filling and sealing process is realized on one station. Meanwhile, the filling valve 1 is compact in structure, the joint of the positive pressure and the raffinate is very close to the product, when high-speed flowing air passes through the joint, residual liquid is completely brought back under the action of positive and negative pressure, and the raffinate is prevented from being reserved in the filling valve 1, so that the raffinate enters a vacuum pump and the service life of the vacuum pump is influenced when the vacuum pump is vacuumized.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
