Description

The computer flat knitting machine laura structure

Technical field

The utility model belongs to the Weaving device technical field, be specifically related to have the Computerized flat knitting machine laura structure of base plate, relate in particular to Computerized flat knitting machine and have the main laura structure of drawing tension governor motion, in traction process, can realize that forward increases pretightning force and reverse decompression power, regulates different transverse area section fabric traction tension force to the segmentation roller roller of cutting apart.

Background technology

Before and after the Computerized flat knitting machine that has had a base plate need be provided with roller carries out tractive to institute's braided fabric, and because of roller one of them roller in front and back need be fixed, another roller is a dynamic adjustments; Roller closure and transmission before and after in the fabric traction process, front and back roller roller need have certain thrust each other, and the size of thrust depends on the fabric and the flower type of braiding.The relative preload pressure of front and back roller of existing Computerized flat knitting machine laura structure is by both sides connecting rod and spring control; this device is very high to the requirement of the machining accuracy of structural member axial length, accumulated error; though can satisfy fabric is carried out tractive; but in the actual use of Computerized flat knitting machine; fabric under most of machine tractives comes flare, in addition there is the fabric of folding and unfolding pin on both sides because the defective of dropped stitch knocking over appears in strain problem regular meeting; sweater producer need be repaired defective products by the suture worker, the waste of manpower financial resources.

The Germany technology personnel improve above-mentioned laura structure, disclosed structure applications is on the main roller device of the serial machines such as CMS340 that the said firm produced, for fixing main roller utilization fragmentation technique one master roller being divided into a plurality of unit axially is tied the cutting unit roller with connector then, simultaneously adjustment structure is set and realizes pretension (power) the roller roller in each segmentation place, but this structure in actual use, have clear improvement on the fabric traction effect than prior art, but because used raw material and the braiding of Computerized flat knitting machine spends type ever-changing, though local tension force can pretension, but the spring force of the dynamic roller closure that adopt on its structure both sides is difficult to control, in the process of braiding thin type fabric, though preload pressure is adjusted to minimum with segmentation place, but still because the fabric undulate that local tension force makes tractive get off too greatly, when weaving thick bodkin fabric, because the regional area section is adjusted less than suitable pretightning force, and local roller roller is worn and torn too early; This structure is difficult to adapt to the requirement of knitting material conversion in a word, has influenced the quality that the user pursues high-grade fabric, for the fabric that Computerized flat knitting machine is compiled has fabric effect preferably, is necessary this laura structure is improved.
