Description
Technical field
The invention belongs to field of textile machinery, and in particular to a kind of traverse cam case for spinning machine.
Background technology
Spinning machine traverse cam case is the indispensable system of all kinds of spinning machines.Traverse cam case major function is：Guide yarn horizontal
To not uniform motion, prevent a yarn reel around when form hard-edge, lap wound, the phenomenon such as the yarn that collapses, make cone yarn forming good, be subsequent handling
It is ready.
The generation of cylinder yarn hard-edge is that reciprocating starting or final position are in same point each time because of yarn guide,
Now because yarn guide speed commutates, must have an of short duration pause, but yarn winding speed is constant, cause yarn in starting or
Winding at this end positions of terminal excessively and be higher by interlude, thus form cylinder yarn hard-edge；The generation of hard-edge will cause cylinder
Yarn forming is bad, soft or hard irregular, and process is unwind after influence.The method for solving this problem allows yarn guide to move each time
Starting or final position are not staggered mutually in same point, so as to mutually stagger in this two positions when ensureing yarn winding, are kept away
Exempt from the appearance of hard-edge phenomenon.
The generation of cylinder yarn lap wound is because caused by traverse cam case yarn guiding speed, i.e. cam invariablenes turning speed.This is solved to ask
The method of topic is exactly to change cam rotating speed, its rotating speed is fluctuated and is achieved the goal within the specific limits.
Other cylindrical cam inevitably produces vibrations, impact at work, and these shake, impacted the direct shadow of conference
The various performances and cone yarn forming of complete machine are rung, therefore it is very important to eliminate these vibrations, the influence of impact.
The winding method of existing spinning machine generally uses Cam reciprocating formula (such as Fig. 1), passes through mechanical gear (differential gear train)
With the yarn guide of cam mechanism driving traversing guide, although this structure is small to filament damage, it is adaptable to the winding of all kinds of yarns.
But it can be seen that this traverse cam case has the following disadvantages from structure：1st, damping device, Suo Youjie are not provided with cam
It is all rigid to touch, and vibration, the impact produced during cam work will be acted directly on lever jack and main frame, easily cause a yarn
Shaping is bad；Though the 2, there is anti-hard-edge device 21, the scope of anti-hard-edge is unadjustable；3rd, this traverse cam case uses one
Cam box individually drives a lever jack 20 to complete guide task, on two-sided spinning machine, it is necessary to each coal face configuration
The cam box of respective numbers, so resulting in the impact of cam box generation does not have other strength to neutralize, offset, and exacerbates cam
Case vibration, influence of the impact to main frame.4th, motion of the connector of lever jack 20 in cam box is linear reciprocating motion, and it is sealed
It is more difficult, easily cause cam box oil leak.
The content of the invention
The present invention provides a kind of traverse cam case for spinning machine, can effectively prevent a formation of yarn hard-edge, improves
Production efficiency, reduces vibrations, reduces equipment cost.
The technical scheme is that, a kind of traverse cam case for spinning machine, including be arranged in cam box and with
Anti- hard-edge device, cam and the output lever mechanism of external impetus input unit connection, it is characterised in that the cam is circle
Post cam, cylindrical cam is located at the center of cam box, and the input shaft of the cylindrical cam and external motive device passes through transmission
Mechanism is connected, and the both sides of cylindrical cam are provided with symmetrical output lever mechanism, and Liang Ge output levers mechanism is respectively by being sleeved on
Sliding block on guide rod is connected with cylindrical cam, and external lever jack is distinguished by Liang Ge output levers mechanism；It is same with external motive device
When connect also have anti-hard-edge device, the anti-hard-edge device include bearing block, eccentric shaft, turbine, aiding support frame and eccentric disk,
Wherein the leading portion of eccentric shaft and stage casing are coaxial, and the leading portion of eccentric shaft is socketed in bearing block by bearing, and the stage casing of eccentric shaft is consolidated
Turbine is connect, the back segment of eccentric shaft is socketed on aiding support frame by bearing, the affixed eccentric disk in rear end of eccentric shaft, its middle (center) bearing
Seat and aiding support frame are fixedly connected with turbine box, are connected between turbine and the input shaft of external motive device by worm shaft,
Offset is passed to cylindrical cam by eccentric disk by bascule, and cylindrical cam can be in camshaft under the promotion of bascule
It is upper to slide.
Further, pressing plate is provided between the upper end of the cylindrical cam and camshaft, is provided with and subtracts between pressing plate and cam box
Shake spring.
Further, the offset of the eccentric disc is 15mm.
Further, picture disruption mechanism is provided between the cylindrical cam and external motive device, the picture disruption mechanism includes
It is convex with cylinder that planetary gear train and the eccentric disc being connected on cam box, wherein planetary gear train are arranged on external motive device input shaft
Between the camshaft of wheel, the planet wheel spindle of planetary gear train is connected by connecting rod with eccentric disc, and eccentric disc passes through picture disruption input shaft
