DETAILED DESCRIPTION

[0019] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0020] Please refer to Figures 1-4 The filter for producing electrode paste adhesive comprises a filter cylinder 1, an inlet valve 2 fixedly connected to the outer surface of the filter cylinder 1, a liquid outlet valve 3 arranged at the bottom of the filter cylinder 1, a transparent cover 4 arranged at the top of the filter cylinder 1, so that the specific conditions of the filter screen disc 8 inside the filter cylinder 1 can be observed through the transparent cover 4, a fixing frame 5 fixedly connected to the outer surface of the filter cylinder 1, a rotating shaft 6 rotatably connected to the inner surface of the fixing frame 5, a sealing ring 7 arranged on the outer surface of the rotating shaft 6, and the sealing ring 7 is arranged at the connection between the fixing frame 5 and the filter cylinder 1, which can ensure the sealing of the filter cylinder 1 and make the rotating shaft 6 smoothly drive the filter screen disc 8 to flip, and the filter screen disc 8 is fixedly connected to the end of the rotating shaft 6 close to the filter cylinder 1 through a driving locking mechanism.

[0021] Through the above technical solution, the electrode paste adhesive can be input from the inlet valve 2 into the filter cylinder 1, and then filtered by the two groups of filter screen discs 8 and discharged from the liquid outlet valve 3 for collection. During the long-term collection process, the filtering efficiency of the filter screen disc 8 may be reduced. At this time, the two groups of filter screen discs 8 can be flipped synchronously through the driving locking mechanism, so that they can be used again after being flipped, thereby effectively prolonging the service life.

[0022] Specifically, the driving locking mechanism comprises a straight rod 9 rotatably connected inside the fixing frame 5, and a rotating handle 91 fixedly connected to the bottom of the straight rod 9.

[0023] Through the above technical solution, the rotating friction between the top of the straight rod 9 and the bottom of the hanger 14 is small, so the straight rod 9 will not drive the hanger 14 to rotate synchronously during the rotating process.

[0024] Specifically, a driving gear 10 is fixedly sleeved on the outer surface of the straight rod 9, a transmission gear 11 is fixedly connected to the end of the rotating shaft 6 away from the filter screen disc 8, and the outer surface of the transmission gear 11 is meshingly connected with the outer surface of the driving gear 10.

[0025] Through the above technical solution, the straight rod 9 will drive the two groups of driving gears 10 to rotate synchronously during the rotating process, and the two groups of driving gears 10 will drive the corresponding transmission gears 11 to rotate synchronously, and finally the rotating shaft 6 drives the filter screen disc 8 to flip.

[0026] Specifically, the inner wall top of the fixed frame 5 is fixedly connected with a lifting ring 12, the lifting ring 12 is hung with a spring 13, the top of the straight rod 9 is rotationally connected with a lifting frame 14, and the top of the lifting frame 14 is fixedly connected with the bottom of the spring 13.

[0027] Through the technical scheme, the lifting frame 14 is composed of the rod body with the top hollowed out, the middle straight plate and the bottom cylinder, and the lifting frame 14 drives the straight rod 9 to move longitudinally synchronously in the process of moving up and down.

[0028] Specifically, the inner side of the outer surface of the fixed frame 5 is fixedly provided with a damping shaft 15, the outer surface of the damping shaft 15 is rotationally connected with a swing arm 16, and the bottom of the swing arm 16 is provided with a ball 17.

[0029] Through the technical scheme, the damping shaft 15 has certain damping characteristics, and when the swing arm 16 is rotated to the corresponding position along the damping shaft 15, it will remain relatively stable state if the force is not applied, and the top of the two groups of swing arms 16 is designed as an arc protrusion, which is used for limiting the straight plate of the lifting frame 14.

[0030] Specifically, the inner surface of the fixed frame 5 is threadedly connected with a screw 18, the bottom of the screw 18 is rotationally connected with a limiting arc plate 19, and the outer surface of the rotating shaft 6 is provided with an annular groove 20.

[0031] Through the technical scheme, when the screw 18 is rotated along the inner wall of the fixed frame 5, the limiting arc plate 19 will not rotate synchronously due to the limitation of the internal space of the fixed frame 5, but will only displace upward and downward with the screw 18.

[0032] Working principle: In the process of filtering the electrode paste binder, the electrode paste binder can be first input from the inlet valve 2 into the filter cartridge 1, and then filtered through the upper and lower two sets of filter screen discs 8 and discharged from the outlet valve 3 for collection (the design of the two sets of filter screen discs 8 can effectively improve the filtering effect). Considering that the long-term collection process can easily lead to a decrease in the filtering efficiency of the filter screen disc 8 (i.e., some mesh holes are blocked), the straight rod 9 can be held and rotated at this time, allowing the two sets of drive gears 10 to rotate synchronously during the rotation of the straight rod 9, and the drive gears 10 will in turn drive the corresponding transmission gears 11 to rotate (at this time, under the resistance of the swing arm 16 to the hanger 14, the straight rod 9 is lowered to a position where the drive gears 10 are just engaged with the transmission gears 11), finally driving the rotating shaft 6 to rotate (at this time, the limiting arc plate 19 is not in contact with the rotating shaft 6), which can realize the turnover of the filter screen disc 8, and the whole turnover process can be observed through the transparent cover 4 (it needs to be particularly pointed out that the gap between the filter screen disc 8 and the inner wall of the filter cartridge 1 needs to be observed during the turnover process of the filter screen disc 8, and when the outer periphery of the filter screen disc 8 is basically attached to the inner wall of the filter cartridge 1, the maximum degree of guarantee for the filtering effect of the filter screen disc 8 is achieved), and then in order to avoid the rotation of the filter screen disc 8 caused by the rotation of the handle 91 during the downward flushing process or external touch, the screw 18 can be screwed, and the screw 18 will drive the limiting arc plate 19 to move downward synchronously during the gradual deepening into the fixed frame 5, until the limiting arc plate 19 tightly clamps the annular groove 20 on the surface of the rotating shaft 6, which can realize the preliminary limiting of the filter screen disc 8 through the rotating shaft 6, and at the same time, the ball 17 is pushed down, so as to rotate the swing arm 16 along the damping shaft 15. During this process, since the top end of the swing arm 16 gradually releases the restriction on the hanger 14, under the elastic resetting action of the spring 13, it will be lifted with the hanger 14, and then drive the straight rod 9 to move slightly upward, so that the drive gears 10 on the straight rod 9 are temporarily disengaged from the transmission gears 11, at this time, even if the handle 91 is accidentally touched by the outside world, it will not have a driving positioning effect on the filter screen disc 8, that is, it plays a locking protection role, and when the filter screen disc 8 is turned over again, the drive gears 10 and the transmission gears 11 will be in engagement state (it needs to be particularly pointed out that the engagement state between the drive gears 10 and the transmission gears 11 is determined by rotating the handle 91 to see whether the filter screen disc 8 rotates or not under the premise that the limiting arc plate 19 does not limit the rotating shaft 6), after the turnover, the water flow will produce a certain flushing force on the surface of the filter screen disc 8 during the downward flushing process, which helps to flush away the small particles attached to the mesh holes on the original surface, thereby restoring part of the filtering effect, and continuing to use, without frequent replacement of the filter screen (it needs to be particularly pointed out that the two filter screen discs 8 only need to be turned over twice and flushed twice by the water flow, so that all the small particles on the two filter screen discs 8 can be flushed away).

[0033] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
