Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery accessories, in particular to a roller leather used for a computer flat knitting machine. Background Art
[0002] Roller leather is a component of the traction transmission mechanism on the computer flat knitting machine. It is a long hollow cylinder, and the surface structure is different according to the applicable occasion. The roller leather of the traditional computer flat knitting machine will have the problem of excessive tension and hair breakage during weaving, especially when weaving yarns with insufficient strength such as cashmere, the hair breakage is more serious. The existing roller leather will open a functional groove on the outer surface to achieve the purpose of releasing tension. The working principle of the existing roller leather is as follows: when the two rollers rotate relative to each other, the surfaces of the two roller leather bodies rotate relative to each other to pull the fabric normally; when the functional groove is opposite to the surface of the roller leather body, part of the traction force is released on the fabric; when the functional groove is opposite to the functional groove, the traction force on the fabric is released. The roller leather body continues to rotate, and different parts are periodically opposite to each other, so that the traction force of the roller on the fabric is kept within a certain range, thereby solving the problem of excessive traction tension of the existing roller leather on the fabric, but the current roller leather still has the problem of inconsistent traction tension during the traction process of the fabric. Summary of the invention

[0007] Furthermore, only one group of the functional belts is provided, and the unit belt is a structure in which a plurality of V-belts are sequentially connected, and the unit belts run through both sides of the roller leather body.

[0009] Furthermore, the conical area of the unit band extends into the opening area of the adjacent unit band. If the sum of the horizontal width line lengths of the conical portion of the unit band extending into the opening area side of the adjacent unit band is b1, then the sum of the width line lengths of the adjacent unit band located on the opening area side is b2, where b=b1+b2.

[0012] Further, the number of the functional bands matches the number of the non-functional bands.
[0013] Furthermore, the step edge of the second step portion of the unit belt is located outside the step edge of the first step portion.
[0014] Furthermore, the center of the roller leather body has a through groove.
[0015] Furthermore, when two groups of roller leathers are used together, the functional belt area of the first group of roller leathers corresponds to the non-functional belt area of the second group of roller leathers, and the non-functional belt area of the first group of roller leathers corresponds to the functional belt area of the second group of roller leathers.

The purpose of this setting is that when the two roller leathers rotate relative to each other, the sum of the lengths occupied by the unit belts in any contact line (that is, the transverse width bus 30) of the two roller leathers corresponding to the functional belt 20 area is equal.

If the sum of the lengths of the horizontal widths of the conical portion of the unit belt 21 extending into the opening area of the adjacent unit belt 21 is b1, then the sum of the lengths of the widths of the adjacent unit belt 21 located on the opening area side is b2, where b= b1+ b2
[0035] When the unit belt 21 is a single V-belt, the functional belt 20 is composed of multiple V-belts wrapped around the surface of the roller leather body 10, and multiple groups of functional belts 20 are arranged at intervals along the axial direction of the roller leather body 10.
