Specific implementation mode
Below in conjunction with attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that is retouched
The embodiment stated is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, originally
The every other embodiment that field those of ordinary skill is obtained without creative efforts, belongs to the present invention
The range of protection.
Embodiment 1, as shown in Figure 1:
Servo twin-tub fluid cushion feeding device, including:Servo motor 1, aluminium seat 4, fixed frame 6, the servo motor 1 are equipped with and watch
Bar 2,2 other end of bar of watching connect the aluminium seat 4, and the aluminium seat 4 is equipped with push rod 5, liquid tank is equipped between the fixed frame 6
8,8 one end of the liquid tank is equipped with liquid threeway closing device 9, and the push rod 5 is through the liquid tank 8 and the liquid threeway
Closing device 9 connects, and the liquid threeway closing device 9 is equipped with leather hose 10, and 10 one end of the leather hose is equipped with throttle valve 14, described
14 one end of throttle valve connects surge tank 12, and 12 top of the surge tank is equipped with water filling cylinder 11, and 12 bottom end of the surge tank is equipped with
Sector buffering mouth 13.
A kind of optimal technical scheme of the present embodiment, 6 bottom end of the fixed frame are equipped with bottom plate 15, and the bottom plate 15 is equipped with and leads
Rail 3, the aluminium seat 4 are slidably connected with the guide rail 3.
A kind of optimal technical scheme of the present embodiment, the servo motor 1, the aluminium seat 4 are individually fixed in the bottom plate
14。
A kind of optimal technical scheme of the present embodiment, the fixed frame 6 are equipped with circular hole, and the push rod 5 passes through circular hole and institute
State the connection of liquid threeway closing device 9.
A kind of optimal technical scheme of the present embodiment is additionally provided with piston 7 inside the liquid tank 8, and the push rod 5 is connected to
The piston 7.
In this embodiment, bar 2 is watched in the drive of servo motor 1, watches the rotation of bar 2 and aluminium seat 4, aluminium seat 4 is driven to be equipped with push rod 5, push away
Bar is equipped with piston 7, and piston 7 is located in liquid tank 8, and liquid tank 8 connects liquid threeway closing device 9, liquid threeway folding dress
9 connection leather hoses 10 are set, leather hose 10 connects throttle valve 14, and throttle valve 14 connects surge tank 12, and 12 upper end of surge tank is equipped with water filling gas
Cylinder 11, lower end are equipped with fan-shaped buffering mouth 13, and 13 lower end of sector buffering mouth connects packaging bag.
Push rod 5 is integrally fixed on aluminium seat 4, and aluminium seat 4 is moved back and forth on fixed frame 6 by guide rail 3, liquid threeway
Closing device 9 can control liquid can flow into liquid tank 8 when 7 pumpback of piston, can not when piston 7 promotes
It flows back but is injected into the leather hose 10 of lower section, throttle valve 14 controls the amount of liquid to be filled, and liquid is noted after entering surge tank 12
Aqueous vapor cylinder 11 makes liquid filling to packaging bag, while the fan-shaped buffering mouth 13 of lower end can disperse liquid to be filled into packaging bag,
