Description
Technical field
The utility model belongs to the auxiliary part technical field of computer plain flat knitter, is specifically related to a kind of active type pulley feed carrier of computer plain flat knitter.
Background technology
As is known in the industry, computer plain flat knitter need be equipped with feed carrier, by feed carrier by the yarn of directly drawing on yarn dish or the yarn sent by yarn feeder is caused knitting mechanism and weave, yarn dish is drawn or the quantity of yarn sent of yarn feeder weaves with the knitting mechanism of computer plain flat knitter time required different colours the quantity of yarn adapt so as to knit out color, fabric that pattern enriches.
TECHNICAL INFORMATION SOURCES about feed carrier can be seen in disclosed Chinese patent literature, as CN102191618A(adjustable elastic yarn clamping mechanism), the directed Yarn guide mechanism of CN102704171A(computer plain flat knitter), the yarn break alarming device of the yarn pretension adjusting mechanism of CN102191623B(computer plain flat knitter) and the broken yarn alarm mechanism of yarn pretension adjusting mechanism of CN102191625B(computer plain flat knitter), etc.
Although be not limited to the configurations of the feed carrier of the patent formula exemplified above, but the trend of the mode of directing thread and the yarn path that also namely yarn enters knitting mechanism is tending towards identical, specifically, yarn is drawn by yarn dish or yarn feeder, warp yarn pretension regulator adjustment pretension, (thread nipper assembly is as Chinese patent CN102704171B to enter thread nipper assembly after going out yarn pretension regulator, shown in CN202011960U and CN103437057A), the yarn guiding ring (also claiming guide porcelain circle) of lever jack (i.e. yarn take-up spring) end is entered after going out thread nipper assembly, embedding yarn hook again on embedding yarn seat (structure about embedding yarn hook specifically can see Chinese patent application publication No. CN103469460A) enters knitting mechanism.
The trend of the structures shape of aforementioned feed carrier yarn and for a long time for industry is built consensus, is especially showed no all information different with it and does not also hear the relevant report that industry queries in disclosed patent up to now and non-patent literature.Particularly as the use manufacturer of computer plain flat knitter, because it thinks that the structure of feed carrier is rational, so the reason of broken yarn too frequently occurred in braiding process to be attributed to the quality (forming the tension force of fiber, the bar evenness of yarn of yarn) of yarn self, the air humidity etc. of braiding environment.But, through the applicant after summarizing the bulk information from the use manufacturer of computer plain flat knitter, and deduce test through simulation repeatedly, found that, cause the factor of yarn breakage except aforementioned yarn qualities and braided ring overseas, to a great extent because of caused by the structure of feed carrier loses rationally.Because yarn in the thread nipper assembly of structural system belonging to feed carrier and the process of embedding yarn hook because thread nipper assembly and embedding yarn hook are in static state, yarn is then in dynamically, so yarn enters knitting mechanism under the state rubbed mutually with thread nipper assembly and embedding yarn hook, frictional force is larger, yarn breakage probability is higher, and yarn very easily occurs neglecting tight loose phenomenon suddenly in the process of advancing to knitting mechanism, have a strong impact on the effect that yarn is steadily carried to knitting mechanism, finally affect the quality of fabric.
From the above, because the guide form of the feed carrier in prior art shows as passive type guide, thus to a certain extent the side effect of adding fuel to the flames is served to broken yarn.
Just in view of above-mentioned technical problem, the applicant once proposed publication No. CN104178930A, name is called the patent application of " active yarn guide of computer plain flat knitter ", the positive effect of this patent application scheme is: help avoid the knitting mechanism that yarn enters computer plain flat knitter under Frotteurism, significantly fall broken yarn probability and make yarn steadily be marched to knitting mechanism.
But still there are following 2 shortcoming in the pulley Yarn guide mechanism that above-mentioned CN104178930A mentions: one, due to a left side, (patent claims first to right block plate, second block plate) structure lose rationally, such as to need in the left block plate chamber of left block plate towards a upper lateral part of right block plate and the middle position being positioned at left block plate chamber forms a left block plate chamber trunnion mount, and in the right block plate chamber of right block plate towards a upper lateral part of left block plate and the middle position being positioned at right block plate chamber forms a right block plate chamber trunnion mount, thus cause for the left side that is shaped, the complex structure of the mould of right block plate, die cost is high, feed carrier is finally caused to lose cheapness, they are two years old, owing to there is yarn from the probability of escaping between left and right block plate, thus escape out after between left and right block plate can twine mutually with adjacent yarn when yarn, disposal can only be shut down in time, otherwise fabric can be made to go out defect, although the probability of yarn escape is relatively low, objectively gives and use the manufacturer of computer plain flat knitter to produce puzzlement.
Summary of the invention
