Description
Technical field
This utility model belongs to spinning machinery field, is specifically related to a kind of automatic lifting bobbin cradle during cone yarn forming
Mechanism.
Background technology
Bobbin cradle lifting mechanism is to realize the critical component that on bobbin cradle, yarn cylinder departs from Wound-up roller and contacts.Cylinder yarn reel
During molding, yarn breaks, and bobbin cradle lifting mechanism needs to make yarn cylinder disengaging Wound-up roller and be parked in defined location to enter
Row Yarn connecting, after Yarn connecting completes, must enable yarn cylinder contact with Wound-up roller rapidly.
China Patent No. is 201310506677.8 to disclose a kind of bobbin cradle, including clamp assemblies, clutch component, double cropping
With cylinder and the locating shaft of bobbin cradle.Clamp assemblies includes revolving bed, and revolving bed is cylindrical tube shape, vertically sets in the middle part of cylindrical drum
Having sector flat plate, be set with one section of hook tooth on the side plate face on fan edge, revolving bed is twisted together and is being positioned at determining of frame frame
On the axle of position.Clutch component and double-acting cylinder are the critical pieces of bobbin cradle lifting mechanism.Clutch component is mainly by lever, company
Bar, electromagnetic clutch, clutch-plate form, and balance pivot is positioned on locating shaft, and connecting rod is vertical, the front end hinge of its upper end and lever
Connecing, lower end is connected with fixing electromagnetic clutch, and the position, middle and lower part in lever plate face is provided with the ratchet and of a band torsion spring
Root extension spring, ratchet coordinates with hook tooth, and the other end of extension spring is articulated on the fixing bar of frame, and the rear of ratchet has one to fix
Push rod；Double-acting cylinder mainly by pushing cylinder body, press piston down, promote cylinder body, promote piston, piston rod and form, two cylinders
Body upper-lower position each other and the fixing connection of coaxial line, be respectively arranged with independent closed cavity, and two pistons are connected with common piston rod；
The piston rod end of double-acting cylinder is hinged on the upper angle at finger plate sector bead, and base is hinged in frame frame.Normally
In spinning process, electromagnetic clutch and clutch-plate are in attracting state, and lever front end is in pressed status, and push rod withstands on ratchet
Making ratchet and hook tooth be in released state below, the clamp assemblies being arranged on revolving bed makes a yarn touch under the effect of cylinder
It is pressed on Wound-up roller.When spinning is interrupted, electromagnetic clutch is controlled to be disengaged with clutch-plate, and the front end of lever is lifted, and ratchet departs from
Push rod is also engaged with hook tooth under the effect of torsion spring, and lever locking revolving bed, extension spring pulls the folder on revolving bed and revolving bed
Hold assembly to rotate, make yarn cylinder depart from Wound-up roller, in order to complete the joint work of yarn.After the piecer of yarn completes,
Electromagnetic clutch is controlled with clutch-plate adhesive, makes bobbin cradle return to normally to spin state.
The defect existing for bobbin cradle lifting mechanism of above-mentioned structure is: structure disperses and complexity, adjustment link is many, completes
One task needs multiple execution actions；After hook tooth contacts with clutch-plate with the disengaging of ratchet and electromagnetic clutch, adhesive is necessary
