Description
Technical Field
The invention relates to the field of computerized flat knitting machines in textile manufacturing industry, in particular to a novel automatic bottom plate lifting device.
Background
When the prior hand-operated flat knitting machine starts knitting, the threading plate is inserted into gaps of front and back needle beds of the flat knitting machine from bottom to top, then a steel wire is manually penetrated through a needle ring at the top end of a needle tooth on the threading plate, the starting on the threading plate forms a closed state, the starting knitting of the flat knitting machine is realized, the starting mode does not need to consume starting yarns, and the requirement of yarn starting can be met. However, in the actual application process, the threading plate needs to be manually threaded with steel wires, a large amount of manpower is consumed, and the full-automatic bottom-lifting function cannot be realized.
Another utility model with the publication number of CN207958632U discloses a bottom lifting device structure. The bottom raising device mainly comprises a bottom raising comb, a sealing wire, a lifting mechanism and a wire feeding mechanism, wherein the sealing wire is controlled by the wire feeding mechanism to penetrate into the bottom raising comb. The lifting mechanism enables the bottom comb to move downwards to provide tension for the knitted piece, after the knitted piece is pulled to the cloth roller to normally draw the knitted piece, the wire feeding mechanism draws out the locking wire, and the computerized flat knitting machine normally knits the knitted piece. Therefore, the effect of no waste yarn starting like a hand flat knitting machine can be achieved, and the production cost is saved. The bottom lifting device matched with the computer flat knitting machine can save waste yarn and improve work efficiency, but the following technical problems are always exposed in the actual use process: one sealing wire adopts two wire feeding wheel surfaces to clamp the sealing wire so as to feed the sealing wire into the bottom lifting comb. However, the phenomenon that the lock wire and the wire feeding wheel are not delivered in place due to slipping frequently occurs in actual operation, so that a large amount of knitting needles of the flat knitting machine are damaged during bottom rising. The two wire feeding wheels can not be drawn out when the sealing lock wire is drawn out, and the three wire feeding wheels and the sealing lock wire are ground for a long time to cause the deformation and the grinding breakage of the sealing lock wire, so that the cloth can not be normally removed by the bottom lifting device. The four lifting devices adopt a double-motor lifting structure, so that the problem that the bottom comb is higher at one side and the other side when the bottom lifting device ascends and descends often occurs, the quality and the bottom lifting effect of a knitted piece are influenced, the production cost is high, and the installation difficulty is high. And the five lifting devices adopt a double-track motion design, the production cost and the installation difficulty are high, and the lower comb can hang the thread end of the weaving piece of the previous piece on the lower comb after the lower comb is reset to cause the lower comb to be difficult to lift next time.
Based on the technical problems, most of computerized flat knitting machine manufacturers are required to weave pieces by adopting a method without waste yarn rising, and the original method of hooking rubber bands or the original method of pulling waste yarns is adopted. To this end, we propose a new automatic floor raising device.
