It should be noted that, referring to fig. 5, the above-mentioned pipe control valves 31 and 32 may include pipe selection pieces 6 and 7, the pipe selection pieces 6 and 7 having through holes 61 and 71, respectively, and the pipe selection pieces 6 and 7 being connected to the compressed gas container 10 through solenoid valves 8 and 9, respectively, the solenoid valves 8 and 9 being used to open the solenoid valves 8 and 9 to release the compressed gas in the compressed gas container 10 and push the pipe selection pieces 6 and 7 to move and finally align the through holes 61 and 71 with the liquid pipes 11 and 12 so that the liquid in the corresponding liquid containers enters the coating die cavity 4 while closing the other liquid pipes when the state of the switching members 51 and 52 is opened. Specifically, the control principle is as follows: when the operator closes the switch member 51, as shown in fig. 6, the solenoid valve 8 is turned on, the corresponding lines thereof are connected, the gas in the gas compression container 10 is released, then as shown in the lower diagram of fig. 5, the compressed gas pushes the line selection sheet 6 forward to align the through hole 61 thereof with the liquid line 11, so that the liquid line 11 forms a passage, the liquid container 21 can enter the coating cavity 4 through the liquid line 11, finally, the coating is completed on the surface of the coating object, after the coating is completed, the switch member 51 can be turned off by the operator, after the pushing of the compressed gas is not completed, the line selection sheet 6 is retracted to the initial position, the through hole 61 is not aligned with the liquid line 11 any more, and other solid parts are aligned with the liquid line 11, so that the passage in the liquid line 11 is closed, because of the inclination of the preset angle, the residual liquid in the coating cavity 4 will continue to flow downwards under the action of gravity, and finally no residual will occur, when the coating cavity needs to be switched to other pipelines, before the coating cavity 4 is filled with the alcohol, the liquid at the bevel of the coating cavity is erased by an operator, so that the problem of mixing two different liquids is avoided, and a linkage mechanism is required to be arranged between the switch parts 51 and 52, that is, when the switch part 51 is closed by the operator, the switch part 52 must be disconnected, and when the switch part 52 is closed by the operator, the switch part 51 must be disconnected, so that two liquid pipelines cannot inject different liquids into the coating cavity at the same time. Similarly, with continued reference to fig. 6, when the operator closes the switch member 52, the solenoid valve 9 is turned on, the corresponding pipeline is connected, the gas in the gas compression container 10 can be released, then, as shown in the upper diagram in fig. 5, the compressed gas pushes the pipeline selection plate 7 forward, so that the through hole 71 on the pipeline selection plate is aligned with the liquid pipeline 12, the liquid pipeline 12 forms a passage, the liquid container 22 can enter the coating cavity 4 through the liquid pipeline 12, finally, coating is completed on the surface of the coating object, after the coating is completed, the switch member 52 can be disconnected by the operator, after the pushing of the compressed gas is not completed, the pipeline selection plate 7 is retracted to the initial position, the through hole 71 is aligned with the liquid pipeline 12, and other entity parts are aligned with the liquid pipeline 12, so that the passage in the liquid pipeline 12 is closed, and the residual liquid in the coating cavity 4 can continue to flow downwards due to the preset angle of inclination, finally, no residual exists, when the coating cavity is required to be switched to other pipelines, before the die is filled, the operator erases the liquid at the inclined opening of the coating cavity 4 with alcohol, so that the two different problems of liquid can be avoided.

According to the embodiment of the coating system provided by the utility model, as the coating system comprises at least two liquid pipelines, the first ends of each liquid pipeline are connected to a corresponding liquid container, the second ends of all liquid pipelines are connected to the coating die cavity through the pipeline control valve, the pipeline control valve is electrically connected to the switch component, the pipeline control valve is used for opening or closing the corresponding liquid pipeline under the control of the switch component, and the pipeline between the pipeline control valve and the inlet of the coating die cavity is inclined by a preset angle above the horizontal plane where the inlet of the coating die cavity is located, so that different types of liquid pipelines can be switched more quickly, the switching efficiency is improved, the phenomenon that different types of liquid share one pipeline can be avoided, and coating abnormality caused by unclean extrusion is avoided.

In a specific embodiment of the coating system, referring to fig. 4, the preset angle may be preferably 45 ° to 60 °, in which case the residual liquid can flow down at a sufficiently high speed, and the angle may be adaptively adjusted according to actual needs, which is not limited herein.
