Detailed description of the invention
Shown in Fig. 1 and Fig. 2, the floating thread pressing roller that the embodiment of the present invention provides, comprise the second support 8 and the first support 9, rotationally and be arranged in two support arms of the second support 8 by bearing, two support arms of the second support 8 are formed by the left and right bending two ends of the second support 8 at the two ends, left and right of thread pressing roller 4.Second support 8 is arranged on two support arms of the first support 9 by bearing pin 12, and wherein, two support arms of the first support 9 are formed by the left and right bending two ends of the first support 9.As shown in Figure 3, the first support 9 is connected with frame 13 by axle.
See Fig. 2, at the two ends, left and right of the first support 9, two locking pins 14 are installed.The hole that the locking end of locking pin 14 is provided with by the first support 9 is flexibly connected with the first support 9, the other end is connected with the cylinder 15 be arranged in frame 13, wherein, cylinder 15 can control unclamping of locking pin 14 and lock, the hole that first support 9 is provided with is between the two ends, left and right of the first support 9, further, the perforate of this Kong Yu frame 13 one side is in opposite directions less than the opening of the first support 9 another side.In addition, cylinder 15 adopts single-acting cylinder, and to guarantee when up-coiler is in off working state, the first support 9 can not swing, and makes thread pressing roller 4 be in a stable position.
As shown in Figure 4 and Figure 5, in order to ensure that locking pin 14 can complete the action of unclamping and locking reposefully, in the present embodiment, is tapered by the profile design of locking pin 14 under the state that the first support 9 is floating.After utilizing tapered locking pin 14 to unclamp, the gap delta between locking pin 14 and pin-and-hole, as the first support 9 can amount of floating.Can change the size of the gap delta value between locking pin 14 and pin-and-hole as required by amount of floating, obtain required amount of floating.Meanwhile, because tapered locking pin is still in pin-and-hole after unclamping, can be linked together with the first support 9 reposefully by the extruding of the conical surface when locking.
Present invention also offers a kind of up-coiler comprising floating thread pressing roller, wherein, the Facad structure schematic diagram comprising the up-coiler of floating thread pressing roller that Fig. 1 provides for the embodiment of the present invention, Fig. 6 is the construction profile schematic diagram of this up-coiler.A rotating rotating disk 5 is installed in the frame 13 of up-coiler, at this rotating disk 5 upper cantilever, two outstanding rotary collet axis of bobbin 6.1 and 6.2 is installed, every root collet axis of bobbin is equipped with multiple paper tube 7.1 and 7.2.Above work collet axis of bobbin 6.1, be installed with a thread pressing roller 4, the top of thread pressing roller 4 is provided with traverse gear 3.
Below the principle of work of floating thread pressing roller provided by the invention and the up-coiler comprising this floating thread pressing roller:
Floating thread pressing roller provided by the invention, second support 8 can around bearing pin 12 in swing together with thread pressing roller 4, and the first support 9 is connected with the frame 13 of up-coiler by pivot 10, the two ends of the first support 9 can be swung up and down in the scope that limits around the pivot 10 being positioned at centre.The locking end of locking pin 14, when swinging at the two ends, left and right of the first support 9, swing ceiling and the lower limit of described first support 9 can be limited, because when the two ends, left and right of the first support 9 are rocked to swing ceiling or swing lower prescribing a time limit, the locking end of the pin 14 that is locked stops by the opening in the hole that the first support 9 is provided with.Cylinder 15 by changing the position of the locking end of locking pin 14, thus can change the size of the gap delta value between locking pin 14 and pin-and-hole, thus changes the swing ceiling of the first support 9 and swing lower limit.
Locking pin 14, when thread pressing roller 4 needs to depart from bobbin upper grip axle, is controlled by the cylinder 15 as engine installation be arranged in frame 13, fixes the first support 9, make thread pressing roller 4 be in stable level attitude.Meanwhile, locking pin 14 can also limit the amplitude of fluctuation of the first support 9, avoids its amplitude of fluctuation excessive.
When carrying out spinning cake switching in spinning process, thread pressing roller 4 needs to lift, and is separated from collet axis of bobbin.In order to ensure that thread pressing roller 4 can lift reposefully and fall, now require that the first support 9 can not swing up and down.By control cylinder 15, unclamp and lock locking pin 14.When up-coiler is in reeling condition, as shown in Figure 4, locking pin 14 unclamps, and freely swing up and down in the scope that the two ends of the first support 9 can limit at, and thread pressing roller 4 floating ground is pressed on spinning cake 21 that work collet axis of bobbin 6.1 is being formed; When needs carry out spinning cake switching or thread pressing roller 4 throws off chuck, locking pin 14 is locked, and as shown in Figure 5, be fixed together with the frame 13 of up-coiler by the first support 9, now, the first support 9 can not freely swing, and thread pressing roller 4 is in stable level attitude.
In a winding cycle, thread pressing roller 4 contacts with the circumference of certain pressure with the spinning cake 21 that work collet axis of bobbin 6.1 is being formed, in order to keep the position of thread pressing roller 4 in a scope limited, rotating disk 5 rotates along with the increase of spinning cake 21 diameter.When spinning cake diameter reaches specified value time, rotating disk 5 rotates on multiple paper tubes 7.2 of being switched to by tow on another collet axis of bobbin 6.2, is in idle collet axis of bobbin 6.2 enters mode of operation at a upper winding cycle, starts a new winding cycle.
The beneficial effect of floating thread pressing roller provided by the invention below:
The hunting range of the first support 9 does not need very large, and generally, thread pressing roller 4 two ends can swing up and down 1-2mm namely can meet requirements.The feature of this structure is, in a vertical plane surface, the two ends, left and right of thread pressing roller 4 can with pivot 10 centre for benchmark swings up and down, automatically parallel with work collet axis of bobbin, floating ground is pressed in work collet axis of bobbin circumferentially, thus reduces the requirement of the parallelism to two collet axis of bobbin.
Because the two ends of the first support 9 can swing up and down in a vertical plane surface, the two ends of thread pressing roller 4 can be swung up and down at position centered by pivot 10, automatically parallel with collet axis of bobbin, floating ground is pressed in spinning cake that work collet axis of bobbin 6.1 is being formed circumferentially.That is, even if the parallel misalignment of two work collet axis of bobbin 6.1 and 6.2 is comparatively large, this thread pressing roller 4 also can automatically parallel with the collet axis of bobbin being positioned at control position, and floating ground is pressed in collet axis of bobbin circumferentially, the contact good with its maintenance.
It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
