During the utility model work, in the every defeated spool of warp, stretch out a warp, on each parallel axle, stretch out a parallel.When variable-frequency motor 11 energising, variable-frequency motor 11 is by secondary gear 13 driven gear axle 14 rotations.The 141 drive parallel knitting mechanism runnings that cog of gear shaft 14, lower gear 143 drives warp knitting mechanical operation.
The braiding process of the utility model braiding machine is as follows:
Gear ring A31 rotation, the projection 32 on gear ring A rotates thereupon, and the side of the runner 34 of warp knitting mechanism will contact with the side of projection 32, rotation along with gear ring A, the runner 34 that is positioned at gear ring A outside can be pushed by projection to the outside of projection, namely make the upper end edge warp tube seat of the defeated spool of warp in gear ring A outside move from inside to outside, and arrive the outer end of warp tube seat 46, the runner 34 that is positioned at gear ring A inner side can inwardly be promoted by projection, and then the upper end edge warp tube seat that promotes the defeated spool of warp of gear ring A inner side inwardly moves, and arrive the inner of warp tube seat 46, gear ring A continues rotation, when projection 32 separates with the runner of being pushed, under the pulling force of spring 35, the defeated spool of warp should be returned to initial position along the counter motion of warp tube seat, but, the position arranging due to projection 32 is the front end two first parallel shuttle 24-1 directions of motion, and under space between adjacent two parallel shuttles, after projection 32 and runner 34 separate, the defeated spool 36 of warp can be continued gear on the position being pulled to by the friction shuttle dish 242 on parallel shuttle, cannot get back to home position, the first parallel shuttle 24-1 passes between the defeated spool 36 of the warp from inside and outside coordinated transposition with parallel, until the first parallel shuttle 24-1 is from after passing between the defeated spool of warp, the defeated spool 36 of warp just resets to home position under the effect of spring 35, that is to say, inner side is got back in the upper end of the defeated spool of warp in gear ring A outside, and outside is got back in the upper end of the defeated spool of warp of gear ring A inner side.Along with the continuation rotation of gear ring B, the second parallel shuttle 24-2 enters between the upper end of the defeated spool of warp of reset, and with another root parallel through between inside and outside two warps after resetting.So just carry out once braiding, completed the braiding process of a net flower.
Such two groups of parallel shuttles constantly shuttle back and forth between two defeated spools of warp that pushed away between two defeated spools of warp of original position and in position, and along with moving on braided fabric, have just formed the continuous tubular knitted layer through knitting device.Because projection has two, parallel shuttle has four, and projection and parallel shuttle rotate a circle, and complete the braiding of four circle parallels.The braiding process of the first parallel shuttle and the second parallel shuttle is carried out in turn, can complete the interleaving process of warp and parallel, thereby constantly forms the braiding of tubular fabric.
The warp passing in the defeated spool of every warp of the present utility model can be provided by the small beam being placed into away from the macro-axis of circular loom, so just in for a long time, does not need to change warp.The warp of macro-axis can be dredged ring and enters the every defeated spool of warp by being arranged on some warps on chassis.When the warp of macro-axis is about to be finished, another beam warp line is continued with it and can guarantee that warp is uninterrupted.And due to the existence of vertical warp, the consumption of parallel also can reduce, also can extend the time that an axle parallel is used.
Being connected and can also realizing in the following way between the defeated spool of the utility model middle longitude and middle spherical crown head: be welded with sleeve pipe on the lateral wall of middle spherical crown head, the internal diameter of sleeve pipe equals the external diameter of the defeated spool of warp, in sleeve pipe, be provided with internal thread, the lower end of the defeated spool of warp is provided with corresponding external screw thread, and the defeated spool of warp is threaded connection and is installed in sleeve pipe; Or by flange, be connected etc. between the defeated spool of warp and sleeve pipe.
The present embodiment is only that content of the present utility model is described and described, and not protection domain of the present utility model is limited, the utility model can also have other implementations, such as gear ring A is made as to ring gear, gear ring B is made as external toothing, changes the arrangement of upper dish and chassis upper-part thereupon; Or the parts in the utility model are carried out to equivalence replacement etc., and this replacement is all within protection domain of the present utility model.
