The specific embodiment
Referring to illustrated in figures 1 and 2, the unsteady thread pressing roller that the utility model embodiment provides, comprise second support 8 and first support 9, the two ends, the left and right sides of thread pressing roller 4 rotationally and be installed in by bearing in two support arms of second support 8, two support arms of second support 8 are that the left and right sides bending two ends by second support 8 forms.Second support 8 is installed in by bearing pin 12 on two support arms of first support 9, and wherein, two support arms of first support 9 are formed by the left and right sides bending two ends of first support 9.As shown in Figure 3, first support 9 is connected with frame 13 by axle.
Referring to Fig. 2, at the two ends, the left and right sides of first support 9, two locking pins 14 are installed.The locking end of locking pin 14 flexibly connects by hole and first support 9 that first support 9 is provided with, the other end is connected with cylinder 15 on being arranged on frame 13, wherein, cylinder 15 can be controlled unclamping of locking pin 14 and lock, the hole that first support 9 is provided with is between the two ends, the left and right sides of first support 9, and the perforate of this Kong Zaiyu frame 13 one side in opposite directions is less than the opening of first support, 9 another sides.In addition, cylinder 15 adopts single-acting cylinder, to guarantee that when up-coiler is in off working state first support 9 can not be swung, makes thread pressing roller 4 be in a stable position.
As shown in Figure 4 and Figure 5, in order to guarantee that locking pin 14 can be finished the action of unclamping and locking reposefully under the state that first support 9 floats, in the present embodiment, be designed to the shape of locking pin 14 tapered.After utilizing tapered locking pin 14 to unclamp, the gap delta between locking pin 14 and the pin-and-hole, but as the amount of floating of first support 9.But amount of floating can change the size of the gap delta value between locking pin 14 and the pin-and-hole as required, obtains needed amount of floating.Simultaneously, because tapered locking pin still is in the pin-and-hole after unclamping, the extruding by the conical surface when locking can be linked together with first support 9 reposefully.
The utility model also provides a kind of up-coiler that comprises the thread pressing roller that floats, wherein, the Facad structure scheme drawing of the up-coiler that comprises the thread pressing roller that floats that Fig. 1 provides for the utility model embodiment, Fig. 6 is the construction profile scheme drawing of this up-coiler.A rotating rotating disk 5 is installed in the frame 13 of up-coiler, at these rotating disk 5 upper cantilevers two outstanding rotary collet axis of bobbin 6.1 and 6.2 is installed, a plurality of paper tubes 7.1 and 7.2 are housed on the every collet axis of bobbin.Above work collet axis of bobbin 6.1 thread pressing roller 4 is installed, the top of thread pressing roller 4 is provided with traverse gear 3.
Below be the unsteady thread pressing roller that provides of the utility model and the principle of work that comprises the up-coiler of this unsteady thread pressing roller:
The unsteady thread pressing roller that the utility model provides, second support 8 can be around bearing pin 12 in swing together with thread pressing roller 4, and first support 9 is connected with the frame 13 of up-coiler by pivot 10, and the two ends of the support 9 of winning can be swung up and down at a restricted portion around the pivot 10 that is positioned at the centre.The locking end of locking pin 14, when the swing of the two ends, the left and right sides of first support 9, can limit swing ceiling and the lower limit of described first support 9, because when the two ends, the left and right sides of first support 9 are rocked to swing ceiling or swing down in limited time, will the be locked locking end of pin 14 of the opening in the hole that first support 9 is provided with stops.Cylinder 15 can pass through the position of the locking end of change locking pin 14, thereby changes the size of the gap delta value between locking pin 14 and the pin-and-hole, thereby changes swing ceiling and the swing lower limit of first support 9.
When locking pin 14 needs to break away from bobbin upper grip axle at thread pressing roller 4, by cylinder 15 controls as engine installation that are installed on the frame 13, fix first support 9, make thread pressing roller 4 be in stable level attitude.Simultaneously, locking pin 14 can also limit the amplitude of fluctuation of first support 9, avoids its amplitude of fluctuation excessive.
When carrying out the spinning cake switching in spinning process, thread pressing roller 4 need lift, and is separated from collet axis of bobbin.In order to guarantee that thread pressing roller 4 can lift and fall reposefully, require first support 9 not swing up and down this moment.By control cylinder 15, unclamp and lock locking pin 14.When up-coiler was in reeling condition, as shown in Figure 4, locking pin 14 unclamped, and the two ends of first support 9 can freely swing up and down in a restricted portion, and thread pressing roller 4 floating grounds are pressed on the spinning cake 21 that is forming on the work collet axis of bobbin 6.1; When needs carried out spinning cake switching or thread pressing roller 4 disengagement chucks, locking pin 14 lockings as shown in Figure 5, were fixed together the frame 13 of first support 9 with up-coiler, and at this moment, first support 9 can not freely swing, and thread pressing roller 4 is in stable level attitude.
At a coiling in the cycle, thread pressing roller 4 contacts with the circumference of the spinning cake 21 that certain pressure and work are forming on the collet axis of bobbin 6.1, for the position that keeps thread pressing roller 4 in a restricted portion, rotating disk 5 is along with the increase of spinning cake 21 diameters is rotated.When the spinning cake diameter reached specified value, rotating disk 5 rotated tow is switched on a plurality of paper tubes 7.2 on another collet axis of bobbin 6.2, is in idle collet axis of bobbin 6.2 in a last coiling cycle and enters mode of operation, begins a new coiling cycle.
The beneficial effect of the unsteady thread pressing roller that following the utility model provides:
The hunting range of first support 9 does not need very big, and generally speaking, thread pressing roller 4 two ends can swing up and down 1-2mm namely can meet requirements.The characteristics of this structure are, in a vertical plane surface, the two ends, the left and right sides of thread pressing roller 4 can be that benchmark swings up and down with pivot 10 centres, automatically parallel with the work collet axis of bobbin, floating ground is pressed on the circumference of work collet axis of bobbin, thereby has reduced the requirement to the parallelism of two collet axis of bobbin.
Because the two ends of first support 9 can swing up and down in a vertical plane surface, make the two ends of thread pressing roller 4 centered by pivot 10, to swing up and down at the position, automatically parallel with collet axis of bobbin, floating ground is pressed on the spinning cake circumference that is forming on the work collet axis of bobbin 6.1.That is to say that even the parallel misalignment of two work collet axis of bobbin 6.1 and 6.2 is bigger, this thread pressing roller 4 also can automatically parallel with the collet axis of bobbin that is positioned at control position, floating ground is pressed on the circumference of collet axis of bobbin, with its maintenance excellent contact.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
