Abstract

Rotating roller for rapier looms, setting a plurality of through spiral rings on the roller body, the coil of the loop is provided with a base tape, the base tape section is provided with a plurality of barbs, barbed cut contradictory On the outer wall of the spiral ring.

Description

technical field

The utility model relates to the technical field of rapier looms, specifically a rotating roller attached to the rapier loom.

State of the art

The rapier loom represents the most widely used shuttleless loom at present. Besides the characteristics of high speed, high degree of automation and high production efficiency of the shuttleless loom, its active weft insertion process has strong variants and can customize weft yarns of all kinds, in addition to multi-color rapier weaving also has a distinct advantage, it can produce up to 16-color weft yarn-dyed products. As shuttleless looms replace shuttle looms, rapier looms will become the primary mode of fabric production.

When using the rapier weaving machine, the even tension of the cloth surface is a very important indicator. In the prior art, the rotating roller of the rapier weaving machine often only uses the edge anvil to drive the textile, so that the textile can be earlier than the middle part, thereby reducing the tension of the textile is not sufficiently uniform and the quality of the textile is impaired.

object of the invention

The purpose of the utility model is to provide a rotating roller that can be used on a rapier loom to make the tension of the textile even.

The above technical problem of the present invention is solved by the following technical solutions: The rotating roller attached to the rapier loom includes a roller body, the roller body is provided with a plurality of spiral rings, a base tape is arranged outside the spiral ring, and on the base tape is a base tape arranged, there are several spine nodes present and the spine nodes lie against the outer wall of the spiral ring.

Furthermore, it is provided that: the base tape is wound obliquely onto the reel body.

Furthermore, it is provided that: the width of the base tape includes at least the threads of three spiral windings.

It is further provided that: a plurality of fixing nails are evenly arranged on the base tape, and the fixing nails are fixed to the reel body.

Furthermore, it is provided that: the mandrel section comprises a knot and a puncture needle connected to the knot, the puncture needle passes through the base band and the knot lies against the outer wall of the spiral ring.

Furthermore, it is specified that: the node is U-shaped.

It is further provided that: an arcuate disc is arranged between the knot and the felting needle and the arcuate disc is attached to the spiral ring.

In summary, the present invention has the following advantageous effects: By providing the spiral ring and the base tape, the mandrel joints can be contacted with the textile evenly, so that the tension of the textile is even and the quality of the textile is ensured.

Ways to carry out the invention

The present utility model is described below with reference to FIGS. 1 to Fig. 4 described in more detail.

The rotation of the roller is applied to a rapier loom, which includes a roller body, the outer peripheral wall of the roller is provided with a plurality of spiral web turns, the bobbin is wound with an obliquely arriving base tape, the base tape can have a certain degree of flexibility in order to ensure the baseband plastic, the thickness of the baseband can be between 2-2.5cm to ensure a stable baseband.

A plurality of spike knots are placed on the base band, which include spike knots U-shaped knots, and puncture needles placed on the outside of the knot turning point. After the base tape is wound onto the reel body, the puncture needle will pass through the base tape and the knot will be glued onto the spiral ring to ensure that the puncture needle will not tilt or shift during use.

Among them, after the base tape is wound onto the reel body, the base tape slightly sinks between the two threads, so that the width of the base tape covers at least the threads of the three spiral turns, which can prevent the base tape from being caught between the thread loops by tightening, and ensure the stability of the carrier tape.

After the base webbing is wound onto the reel body, a series of fixing nails are evenly placed on the base webbing, and the bottom of the fixing nails are nailed to the reel body to fix the base webbing and ensure the stability of the base webbing during use. This specific embodiment is only an explanation of the utility model and does not constitute a limitation of the utility model. After reading this specification, those skilled in the art can make modifications to this embodiment as needed without creative input, as long as the utility model uses the scope of the new type of claims is through protected by patent law.
