Description
Technical field
The utility model belongs to the computer plain flat knitter technical field, is specifically related to a kind of yarn pretension adjusting device of Yarn-feeding mechanism of computer plain flat knitter
Background technology
Because yarn pretension adjusting device is installed in the sidepiece of computer plain flat knitter usually, therefore the industry custom is called side antenna pretension adjusting device, and the yarn of being sent into by yarn feeder is introduced the head of the knitting mechanism of computer plain flat knitter through this yarn pretension adjusting device.The self-evident function of line yarn pretension adjusting device is that the tension force of yarn is regulated, to ensure the yarn feeding effect, because the tension force of yarn is not constant, both be subjected to the influence of self material and changed, be subjected to the difference of weather such as environment temperature and humidity again and change, therefore the process of knitting mechanism braiding need according to a certain a few or all the tension force of yarns in time regulate.
The structure of the yarn pretension adjusting device of the Yarn-feeding mechanism of known computer plain flat knitter as shown in Figure 3, comprise a substrate 1, one fixed axis 2, one group of guide arm 3, one group of lever jack 4(industry that equates with guide arm 3 quantity also claims yarn take-up spring) and a signal response bar 5, substrate 1 is fixed on the fixed axis 2 by a pair of fixedly ear 11 of one side, one end of one group of guide arm 3 is arranged on the fixed axis 2 rotationally, one end of conductor rod 4 and the other end of guide arm 3 are fixed, and the other end of lever jack 4 constitutes free end and be fixed with a yarn guiding ring 41, signal response bar 5 is arranged on the fixed axis 2 rotationally, and top corresponding to lever jack 4, wherein constitute an extension spring hanging feet 31 on each guide arm 3, and on substrate 1, be provided with the tension spring tension adjusting slider 12 that one group of quantity equates with the quantity of guide arm 3 movably, one end of not shown extension spring is fixed on the extension spring hanging feet 31, and the other end of extension spring and tension spring tension adjusting slider 12 are fixing, can change the pivot position of guide arm 3 on fixed axis 2 by adjusting tension spring tension adjusting slider 12 in the position on the substrate 1, and then change the position of lever jack 4, regulated thereby make by way of the tension force of the yarn of yarn guiding ring 41.When the fracture situation appears in the yarn for the knitting mechanism braiding by yarn feeder output, lever jack 4 is bounce-back and bump signal response bar 5 under the effect of extension spring just, upwards upset of signal response bar 5, and touch the signal picker that is provided on the computer plain flat knitter (as microswitch, travel switch, position near switch or hall sensing element), so give controller with signal feedback by signal picker, knitting mechanism is quit work, enter braiding again after yarn to be ruptured continues.
Illustrated among Fig. 3 and be used to provide one group on 8 road yarns (but being not limited to 8 tunnel) i.e. 8 guide arms 3 and 8 lever jacks 4, with the different colours yarn that satisfies braided fabric for the yarn requirement.
Because said structure only relies on the position of tension spring tension adjusting slider 12 on substrate 1 to change the tension force of regulating yarn, thereby in the use of reality, expose following shortcoming: one, because the extension spring meeting produces tired, therefore be difficult to guarantee lasting regulating effect; Its two, the pulling force of extension spring is difficult to control, it is bigger to change surplus, even under the situation of not changing yarn, the tension force of yarn can be in the same old way because of the variation of tension spring tension changes, need in time handle (in time adjusting), thereby increased working strength of workers by the online assignment personnel.
Undoubtedly, if guide arm 3 can be locked in adjusted position, so aforesaid problem just can be eliminated, but in disclosed patent and non-patent literature, there is no all corresponding techniques enlightenments that has, the applicant has made good try for this reason, find a way to resolve the problem, and the experiment proved that it is practicable, technical scheme described below is based on producing under this prerequisite
