Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2 and Figure 3, the flush coater plunger device of the present embodiment, including be arranged in flush coater cylinder 4
Plunger bushing 1 is arranged in 1 lower end of plunger bushing and the piston 5 and plunger rod 2 that are slidably located in cylinder 4；Setting in plunger bushing 1
There is inner cavity 15；From the upper end of plunger bushing 1, sliding penetrates inner cavity 15 for the lower end of plunger rod 2；The lower end of plunger rod 2 is provided with one
Slide up and down the end 21 being set in inner cavity 15；The diameter of end 21 is more than the diameter of plunger rod 2；The upper end of inner cavity 15 is arranged
There is a tight mouth 14 for preventing end 21 from skidding off plunger bushing 1；15 upper-lower height of inner cavity moves up and down stroke less than plunger rod 2；Column
The fuel feed hole 11 passed in and out for lubricating oil and oil outlet 12 are provided on the side wall of plug sleeve 1, fuel feed hole 11 and oil outlet 12 are communicated in
In plunger bushing 1 and between the upper and lower away from setting；Flush coater plunger device further includes drive plunger rod 2 in the axial reciprocal fortune of plunger bushing 1
Dynamic rotating shaft mechanism 3；Rotating shaft mechanism 3 include one can around its axis rotation flywheel 31, be fixed at the eccentric position of flywheel 31
The connecting pin 32 set and connecting rod 33；One end of connecting rod 33 is rotatablely connected with connecting pin 32, the other end and plunger rod 2
Upper end is hinged.
Preferably, the plunger bushing 1 is provided with dismounting end face 13, the dismounting on one end side wall of rotating shaft mechanism 3
End face 13 coordinates with extracting tool so that plunger bushing 1 is disassembled from cylinder 4.
The operation principle of the utility model：
Flywheel 31 on rotating shaft mechanism 3 is connected in power plant.When power plant starts, flywheel 31 is driven to rotate.
Around the axe movement of flywheel 31, the other end of connecting rod 33 drives on plunger rod 2 for one end that connecting rod 33 is connect with connecting pin 32
Lower direction, which is labored, fills in movement.Because the upper-lower height of the inner cavity 15 in plunger bushing 1 moves up and down stroke less than end 21,
End 21 also can drive plunger bushing 1 to move up and down in cylinder 4 when up and down motion, the reciprocal up and down motion of plunger bushing 1
It pressurizes for cylinder 4, the coating in cylinder 4 just has enough pressure to be sprayed with the state of atomization from the nozzle of flush coater.End
Ceaselessly by oil outlet 12 and fuel feed hole 11 while 21 up and down motion, lubricating oil plays lubrication in inner cavity 15 and end 21
With the effect of buffering, protective terminal 21 and inner cavity 15.
When needing replacing piston 5 or repairing replacement to plunger bushing 1, the side wall of plunger bushing 1 is that periphery is inconvenient
It is grasped in common extracting tool.The dismounting end face 13 being arranged on the upper end side wall of plunger bushing 1, setting dismounting end face 13 be in order to
Tool easy to disassemble can be closer fitting, so as to be easier plunger bushing 1 is disassembled and is installed out of cylinder 4.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are equally included in the patent within the scope of the utility model.
