Detailed Description

The tension roller for the computerized flat knitting machine of the present invention is further described with reference to fig. 1 to 4.

A pull roller for a computerized flat knitting machine is characterized in that: comprises a roller body 2 and a leather sheath 1 sleeved on the roller body 2; the outer surface of the leather sheath 1 is densely provided with traction convex thorns 3 which protrude out of the outer surface of the leather sheath 1; the traction convex thorns 3 are in a circular truncated cone shape, and the upper bottom surfaces of the circular truncated cone-shaped traction convex thorns 3 are in a hemispherical surface 31 structure.

When using, roller or back roller change before the utility model discloses a pulling force roller 4, the fabric that need be by the individual tractive is located pulling force roller 4 one side, and the roller changes before this embodiment the utility model discloses a pulling force roller 4 is the example, forms roller mechanism. When the double-layer fabric is drawn, under normal conditions, the double-layer fabric 6 is tightly pressed by using the tension roller 4 and the back roller 5, so that the double-layer fabric 6 is jointly drawn or fed; when a layer of fabric 61 needs to be pulled, the distance between the rear roller 5 and the tension roller 4 is adjusted, so that the tension roller 4 and the rear roller 5 loosen the clamping of the double-layer fabric 6, meanwhile, the single-layer fabric 61 needing to be pulled is positioned on the tension side of the tension roller 4, the pulling spines 3 on the tension roller 4 are embedded into the single-layer fabric 61, the single-layer fabric 61 is pulled by the tension roller 4 independently, subsequent independent spinning is realized, and after the independent spinning is finished, the distance between the tension roller 4 and the rear roller 5 is adjusted according to actual requirements, so that double-layer common pulling, single-layer pulling or non-pulling is realized.

The embodiment is further configured as follows: the included angle between the side wall and the bottom wall of the circular truncated cone-shaped traction lug 3 is 75-85 degrees. Under the inclination angle, the pulling convex thorns 3 can be conveniently embedded into the fabric so as to pull the fabric; meanwhile, the pulling roller 4 can drive the fabric to convey the fabric for a certain distance, the pulling convex thorns 3 are separated from the fabric, and the problem that the fabric is damaged due to the fact that the pulling convex thorns 3 are difficult to separate from the fabric is solved.

The embodiment is further configured as follows: the leather sheath 1 is a resin leather sheath 1. The friction force of the resin material is large, so the friction force of the resin leather sheath 1 is used for the preferable technical scheme of contacting, rubbing and pulling with the fabric.
