Abstract

The utility model belongs to textile machinery and in particular relates to a layered roller ribbon loom. The layered roller ribbon loom comprises a knitting machine and a warp frame and is mainly characterized in that hundreds of grey yarns can be stored on the warp frame, a roller device is connected between the grey yarns on the warp frame and a guide rod, the roller device mainly comprises a roller frame, a roller and roller guide rollers, the roller and the roller guide rollers are fixed on the roller frame, and two roller guide rollers are arranged at two sides above the roller. According to the layered roller ribbon loom provided by the utility model, one roller is added, and a pressure is applied to warps by virtue of weight of the roller, so that steady and uniform tension of each warp is realized, the defect that quality of a woven belt is influenced as warps jump up and down along with up-down motion of a warp slice can be avoided, tension of each warp is uniform, the smoothness of the woven belt is high, and yarns contained by each grey yarn are far longer than the warps in the existing warp coil, so that a longer belt can be woven, a warping process is eliminated and the cost is reduced.

Description

Layer-stepping roller inkle loom

Technical field

The utility model belongs to textile machine, especially belongs to layer-stepping roller inkle loom.

Background technology

Existing inkle loom as shown in Figure 1, mainly by braiding machine 1, form through coil holder 2, on coil holder 2, be fixed with 10-20 through drum 21, warp will pass through warping (warp thread length in accordance with regulations and the width of certain radical is wound on technical process on dish) many warp thread are become one through drum on a coiled hair, again warp is walked around on the warp sheet that guide rod 23 is through at braiding machine, parallel places the shuttle side to weave, because guide rod only play the guiding role to warp, each bar warp exists tension force inhomogeneous when braiding, and affect the flatness of braid over braid, and the length of ribbon is subjected to the long-pending restriction of warp disk body.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming that above-mentioned inkle loom exists, and a kind of warp even tension is provided, and can guarantee the layer-stepping roller inkle loom of the flatness of braid over braid.

The technical scheme that the utility model adopts is a kind of layer-stepping roller inkle loom, it comprises braiding machine, through coil holder, its main points are can deposit up to a hundred raw yarn grains on coil holder, between the raw yarn grain of coil holder and guide rod, be connected with roller device, described roller device mainly comprises roller frame, roller and roller deflector roll, roller, roller deflector roll are fixed on the roller frame, two both sides of roller deflector roll above roller.

Many warp raw yarns are parallel to be walked around first roller deflector roll and walks around roller again, be through on the warp sheet of braiding machine by guide rod behind second roller deflector roll, in walking in the line process of warp, synchronous rotation by roller and both sides, top guide rod, so that the warp maximum area fits perfectly in surface of roller, strengthen the friction between roller and the warp thread, each is realized steadily evenly through line tension, avoided producing the quality that bob affects braid over braid because moving up and down of warp sheet makes warp, each bar warp even tension, the belt flatness that weaves is high, simultaneously because the contained warp of each raw yarn grain is longer than existing length through the drum middle longitude far away, therefore the belt length that can knit is longer, and omitted warping process, reduce cost.

The centre-to-centre spacing of two roller deflector rolls is less than the diameter of roller.Warp is stressed more even apart from large with contacting of roller like this.

The quantity of roller is identical with the quantity of guide rod.

Or the quantity of roller is guide rod quantity half.

Because raw yarn grain quantity is many, so be greater than the width of roller frame through the width of coil holder, and the width of band is much smaller than the width of roller frame, usually only has 1/5th to 1/20th of roller width, the quantity of guide rod is determined by the Weaving pattern of being with, the used warp of one row's warp sheet only accounts for 1/4th to 3/7ths of a surface of roller, therefore can reduce roller quantity, thereby reduces the volume of single unit system.

The utility model is by increasing a roller device, utilize the weight of roller that warp is exerted pressure, in walking in the line process of warp, synchronous rotation by roller and both sides, top guide rod, so that the warp maximum area fits perfectly in surface of roller, strengthen the friction between roller and the warp thread, each is realized steadily evenly through line tension, avoided producing the quality that bob affects braid over braid because moving up and down of warp sheet makes warp, each bar warp even tension, the belt flatness that weaves is high, simultaneously because the contained warp of each raw yarn grain is longer than existing length through the drum middle longitude far away, therefore the belt length that can knit is longer, and has omitted warping process, reduces cost.

The specific embodiment

Below in conjunction with view the utility model is described in detail

As shown in Figure 2, a kind of layer-stepping roller inkle loom, it comprises braiding machine 1, through coil holder 2, on coil holder 2, be fixed with up to a hundred raw yarn grains 22, between the raw yarn grain 22 of coil holder 2 and guide rod 23, be connected with roller device 3, described roller device mainly comprises roller frame 31, roller 32 and roller deflector roll 33, roller 32, roller deflector roll 33 is fixed on the roller frame 31, two both sides of roller deflector roll 33 above roller 32, the centre-to-centre spacing of two roller deflector rolls 33 is less than the diameter of roller 32, half that the quantity of roller 32 and the quantity of guide rod 23 quantity identical or roller 32 are guide rod 23 quantity.It is same as the prior art that all the other do not state part.
