Prevent that dregs leaks when screw machine from going out dregs, screw machine outlet outside spacers are symmetrically and evenly distributed four hinged oil cylinders, are hinged oil
Cylinder is provided with stroke sensor and control valve group, and the both ends of hinged oil cylinder are respectively positioned at the static position of screw machine outlet and action
Part, both ends and the screw machine outlet hinged place of hinged oil cylinder are equipped with free bearing, to ensure that screw machine outlet can be formed necessarily
Swing angle, described infrared transmitting device are used to launch infrared ray, and described infrared receiver is infrared for receiving
Line signal simultaneously calculates screw machine outlet and the offset of belt feeder, and described four hinged oil cylinders are divided into two groups, upper next group,
One group of left and right, group oil cylinder and left and right group oil cylinder move in opposite directions up and down for control valve group control.
Multiple grease hand-holes are uniformly provided with above-mentioned screw machine hinged sealing ring, for for the static position of screw machine with
Position lubrication is acted, while strengthens sealing effectiveness.
It is above-mentioned to set be hinged overhang as " 0 " position in program when hinged oil cylinder stretches out half, pass through infrared receiver
The offset of screw machine and belt feeder is calculated, be hinged control valve group is stretched out to hinged oil cylinder makes appropriate adjustment with retraction, protects
Card screw machine axis aligns with belt feeder axis, and dregs will not fall on the outside of belt feeder.
Above-mentioned control valve group is proportional reversing valve, and the data feedback gone out by infrared rays survey provides electric signal and controls it
Opening degree, control error are no more than 10%.
Electric control system is connected in above-mentioned control valve group.
Above-mentioned hinged oil cylinder is provided with limit switch.
Beneficial effects of the present invention：
1st, screw machine is unearthed and accurately fallen on belt feeder, prevents dregs from going out on the outside of belt feeder, improves operating efficiency；
2nd, the security reliability of product is improved, reduces product cost, reduces the wasting of resources, improves operating efficiency；
3rd, operated by control system, it is convenient and swift, greatly improve labor productivity.
