Background technology
Existing extrusion coater realizes the mode of interval coating, is all to be realized by the supply lines conversion of coating tapping mode valve, the structure of tapping mode valve for interval be coated with accuracy to size, consistency of thickness control most important.
As shown in Figures 1 and 2, extrusion coating machine tapping mode valve is made up of valve body 1, actuator 3, sealing ring 4 and piston rod 2, screw thread is adopted to be fixedly connected with between sealing ring 4 and piston rod 2, namely sealing ring 4 can stretch out with piston rod 2 or retract, valve pocket 11 is provided with in valve body 1, in valve pocket 11, valve pocket inner ring 14 is circumferentially set, valve pocket inner ring 14 is suitable with sealing ring 4, valve body 1 is also provided with charging aperture 12 and discharging opening 13, when during startup, actuator 3 piston rod 2 moves up and down, sealing ring 4 can move together along with piston rod 2.
The patent No. be 201310738616.4 patent discloses a kind of opening or closing time can keep the baffle stop valve of the valve pocket constancy of volume, comprise valve body, spool and drive rod, valve body offers valve pocket, in valve pocket, drive rod is set, drive rod is fixedly installed spool, when drive rod moves up and down, spool can move together along with drive rod.
Two kinds of above-mentioned following problems of technology ubiquity: because piston rod (drive rod) moment translational speed is fast, therefore sealing ring (spool) and piston rod can produce release effect instantaneously to the coating fluid above it, coating chamber discharging opening pressure is caused to increase instantaneously, exceed normal coating pressure, thus cause the situation that interval coating head is partially thick.
In order to solve the partially thick situation of above-mentioned head, current method is slowed down at the translational speed of piston rod, coating fluid moment speed to introduce reduced, reaches the object controlling interval coating head thickness.But, owing to reducing the translational speed of piston rod, namely reduce the response time of interval coating valve, when result in high-speed coating, the technological requirement of short interval and short dispensing area cannot be realized, thus reduce the technique adaptive capacity of extrusion coating machine.And the coating method of this short interval, the technique of current most of lithium battery manufacturers employing just.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of separate type coating tapping mode valve, and this separate type coating tapping mode valve effectively can solve the thicker problem of booting moment coating head.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of separate type to be coated with tapping mode valve, described valve body is arranged charging aperture and discharging opening and in valve body, valve pocket is set, described charging aperture and discharging opening are communicated with described valve pocket respectively, the internal face of the valve pocket between described charging aperture and discharging opening circumferentially arranges valve pocket inner ring, described piston rod one end connects described actuator, the other end passes the central passage of valve pocket inner ring and stretches to described discharging opening, also comprise sealing ring, described seal ring set is connected to the other end of piston rod and can moves along piston rod, described sealing ring and described valve pocket inner ring is suitable coating is cut off or channeling fluid path.
Further, the other end end of described piston rod arranges projection, and described sealing ring moves to projection place to be stopped.
Further, the section of described projection is triangle.
Further, the internal diameter of the central passage of described valve pocket inner ring is not more than the external diameter of sealing ring.
Further, described sealing ring is fitted in the side of described valve pocket inner ring, and the fluid passage between charging aperture and discharging opening is cut off.
Further, described sealing ring is connected in the central passage of described valve pocket inner ring, and the fluid passage between charging aperture and discharging opening is cut off.
The beneficial effects of the utility model are: sealing ring and the piston rod of the utility model coating tapping mode valve adopt separate type, namely seal ring set connects and makes sealing ring can along piston rod relative sliding on the piston rod, when being coated with tapping mode valve and opening, piston rod high-speed motion and sealing ring can not move thereupon under the driving of actuator, sealing ring is the pressure jack-up by coating fluid, its opening speed is by the Stress control of coating fluid, be consistent with the flowing velocity of coating fluid, therefore can not produce to coating fluid the effect released, because the sectional area of piston rod is little, its thrust produced coating liquid is minimum, therefore the change having influence on interval coating head thickness is not enough to, thus effectively solve the thicker problem of booting moment coating head.
