The specific embodiment
Computer flat knitting machine roller circle of the present utility model is got mechanism and is related to two kinds of versions, and a kind of is shown in Fig. 1-2, and another kind as shown in Figure 5.
The computer flat knitting machine roller circle of first kind of structure is got mechanism such as Fig. 1, shown in 2, computer flat knitting machine roller circle is got mechanism and is comprised that two circles get bobbin, circle is got bobbin and is comprised screw rod 5, roller bearing 4 and roller sebific duct 3, described screw rod 5 is as driving wheel, roller bearing 4 drives as driven pulley and is nested with at screw rod 5, roller bearing 4 outer roller sebific ducts 3 rotate, also be provided with back-up block 6 between screw rod 5 and the roller bearing 4, two circles are got between the roller sebific duct 3 of bobbin and are left the crack that the tractive circle is got, sprocket wheel 1 shown in motor-driven Fig. 1, sprocket wheel 1 drives screw rod 5 by gear-box 2 and rotates, screw rod 5 drives roller sebific duct 3 and rotates, and braided fabric downward tractive circle in crack is got.
Another kind of computer flat knitting machine roller circle is got mechanism's (also claiming the secondary roller circle of computer flat knitting machine to get mechanism) and as shown in Figure 5, is comprised two compress wheels 13, and motor-driven compress wheel 13 rotates the downward tractive circle of braided fabric that two compresses are taken turns between 13 slits and gets.
The computer flat knitting machine roller circle of structure is got mechanism and be provided with pull bar 8(as shown in Figure 3 in described screw rod 5 as shown in Figure 1, 2), described pull bar 8 passes from screw rod 5 two ends, be provided with pre-gravitation mechanism at the two ends of pull bar 8, described pre-gravitation mechanism stretches pull bar 8, increase rigidity, make its maintenance straight.
The computer flat knitting machine roller circle of structure shown in Figure 5 is got mechanism and be provided with pull bar 8 in described compress wheel 13, described pull bar 8 is taken turns 13 two ends from compress and is passed, and is provided with pre-gravitation mechanism at the two ends of pull bar 8, and described pre-gravitation mechanism stretches pull bar 8, increase rigidity, make its maintenance straight.
Above-mentioned embodiment is outer surface and screw rod 5(or the compress wheel 13 of acquiescence pull bar 8) inner surface contact, straight like this pull bar 8 has guaranteed to be in contact with it screw rod 5(or compress takes turns 13) straight.And under this mode, the situation that may occur is: pull bar 8 is static, and screw rod 5(or compress wheel 13) rotates, the outer surface of pull bar 8 and screw rod 5(or compress wheel 13 like this) inner surface between the meeting generation rub.
The pre-gravitation mechanism principle that two kinds of computer flat knitting machine roller circles are got mechanism in the utility model is the same, the pre-gravitation mechanism specific embodiment, principle are identical, and the selection use of support ring etc. all is identical, and embodiment that the computer flat knitting machine roller circle of structure shown in Figure 5 is got mechanism waits and do not repeat them here.Only getting mechanism with the roller of structure computer flat knitting machine shown in Fig. 1,2 circle at this is elaborated:
As shown in Figure 3, described pre-gravitation mechanism comprises screw head 7, be provided with pull bar 8 in the described screw rod 5, described pull bar 8 passes from the screw head 7 at screw rod 5 two ends, two end surfaces of described pull bar 8 are screw-like, are connected with lock nut 9 on it, described lock nut 9 rotations, being the strong point with screw head 7 when rotating to screw head 7 places stretches pull bar 8, makes its maintenance straight.The rotation of lock nut 9 is not unlimited, be fulcrum with screw head 7, the length of rotation can guarantee that pull bar 8 get final product when straight, and this moment, can also by alignment pin 12 fix pull bar 8 and screw head 7 at screw head 7 this moment with the fixed-site of lock nut 9 on pull bar 8.Under this mode, pull bar 8 is to rotate synchronously with screw rod 5.
Usually, the internal diameter of screw rod 5 is far longer than the external diameter of pull bar 8, and described pull bar 8 on evenly be arranged with a plurality of support rings 10, outer surface studdle 5 inner surfaces of described support ring 10 in described screw rod 5 inside this moment.When the internal diameter of screw rod 5 during greater than the external diameter of pull bar 8, under the support of support ring 10, screw rod 5 is will be all the time the same with pull bar 8 to keep straight.
In order to prevent that support ring 10 breaks away from desirable Support Position, keep its fixed position of supporting screw rod 5 all the time, as shown in Figure 4, described support ring 10 is fixed on the pull bar 8 by hold-down screw 11.
Under aforesaid way, the situation that may occur is: pull bar 8 is static, and screw rod 5 rotates, like this support ring on the pull bar 8 10 can and the outer surface of pull bar 8 or and the inner surface of screw rod 5 between produce friction.In order to reduce friction, described support ring 10 can adopt bearing, and the inner ring of bearing is installed on the pull bar 8, and the outer ring of bearing contacts with the inner surface of screw rod 5.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
