Problems solved by technology
[0002] Today's lithium battery slurry coating mainly uses pneumatic feeding valves. It takes a long time for the cylinder to start and stop during work, which has the disadvantage of being unable to achieve small intermittent coating, and the coating accuracy of pneumatic feeding valves is low, so it cannot be applied. For occasions that require high precision, its scope of use is greatly limited, and the valve body adopts an integral structure, which is inconvenient to disassemble and clean

The invention provides a servo coating feed valve. A feed valve and a material return valve are arranged on the left side and the right side of valve bodies correspondingly. The upper portion of the feed valve and the upper portion of the material return valve are connected with a feeding connecting pipe and a discharging connecting pipe through two first hoops correspondingly. A hollow cavity isformed in each of the feeding connecting pipe and the discharging connecting pipe. A feeding valve cover is arranged in an inner cavity in the seam of the feeding connecting pipe and the feed valve, and the lower portion of the feeding valve cover is connected to an eccentric cam through a valve element rod. A discharging valve cover is arranged in the joint of the discharging connecting pipe andthe material return valve, and the lower portion of the discharging valve cover is connected to an eccentric cam through a valve element rod. Two servo drive mechanisms are connected to one sides of the lower portions of the valve bodies side by side, and the servo drive mechanisms are connected to the eccentric cams. According to the servo coating feed valve, the chuck type fast connecting manneris adopted between the two valve bodies and pipelines, and demounting and cleaning are facilitated; the valve element rods are driven by servo motors, and it is guaranteed that the valve covers are fast opened and closed during coating and stopping; and compared with traditional pneumatic valves, the coating precision is improved overall.
Description
technical field [0001] The invention relates to the technical field of slurry coating for lithium batteries, in particular to a servo coating feeding valve. Background technique [0002] Today's lithium battery slurry coating mainly uses pneumatic feeding valves. It takes a long time for the cylinder to start and stop during work, which has the disadvantage of being unable to achieve small intermittent coating, and the coating accuracy of pneumatic feeding valves is low, so it cannot be applied. For occasions that require high precision, its scope of use is greatly limited, and the valve body adopts an integral structure, which is inconvenient to disassemble and clean. Contents of the invention [0003] In order to overcome the defects of the prior art, the invention provides a servo coating feeding valve capable of coating high-precision products. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] Se...
