Abstract

The utility model discloses a compact spinning device with rollers and leather rollers, which relates to the technical field of textile machinery. A plurality of ring-shaped slots are arranged on the outer surface of each roller, and ring-shaped raised lines matched with the ring-shaped slots are arranged on the outer surface of each leather roller. Compared with the prior art, the compact spinning device is simple in structure, low in modification cost and easy in mounting without adding auxiliary equipment and affecting running speed and normal production technology.

Description

The roller roller closely spins

Technical field

The utility model relates to technical field of textile machine, and especially a kind of roller roller closely spins.

Background technology

The present most fine spining machine of China improves howsoever; All be to come from the traditional processing technology in more than 100 year, promptly rove carries out the drawing-off first time through rear roller entering middle roller, gets into front roller through middle roller through upper and lower pin again and carries out the drawing-off second time; Because the front roller outer surface has twill; And the roller outer surface is smooth, just reach the purpose of drawing-off through the extruding of rolling, and gets into twisting area because the extruding drawing-off of rolling makes rove form sheet; This head, tail that just produces fiber is exposed at the yarn outside outward, thereby produces a large amount of " filoplume "; And what of " filoplume " are very important quality index of spinning quality, thereby capture the key subjects that " filoplume " is current domestic and international weaving scientific research; And closely spin at present is current ripe relatively scientific achievement, and roller compact spinning is returned in air draught like grid ring, and the air draught of card mill yarn micropore roller is closely spun or the like; Their common characteristic all are before final resultant yarn that the fiber alignment combing is smooth and easy, when twisting, wrap sth. made by twisting to fiber end to end in yarn as far as possible, make " filoplume " minimizing, yam surface smooth; But so following shortcoming of technological ubiquity: 1, increase energy resource consumption, increase auxiliary equipment, increase consumable accessory; According to statistics, every fine spining machine will increase various expenses more than 20,000 yuan every year, and the speed of a motor vehicle also receives certain control; Like this, improvement expenses is too high, increases operating cost; 2, stopping production maintenance regularly, cleaning so just increase the equipment control difficulty.

The utility model content

The utility model provides a kind of roller roller closely to spin, and it can solve existingly spins closely that when putting into operation improvement expenses is high, operating cost is high and the problem of must regularly stop production maintenance, cleaning.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: it includes roller and roller, and said roller outer surface is provided with several grooves that are round, and said roller outer surface is provided with the round raised line that matches with said groove.

In the technique scheme, scheme is more specifically: described groove can be dovetail groove, also can be arc-shaped slot, can also be Baltimore groove; Said groove contacts with the surface of said raised line.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, owing to just have and orthogonal several grooves of roller axial line at the roller outer surface, the roller outer surface is provided with the raised line that is meshed with groove, and is simple in structure, and improvement expenses is low, improvement expenses have only other similar closely spin 1/2nd to 1/3rd.

2, be easy to install, only need to be contained in the utility model on the position of front roller and front leather roller of existing fine spining machine and get final product, need not increase auxiliary equipment, also do not influence the speed of a motor vehicle, do not influence normal production process.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is that surface of roller is the structural representation of dovetail groove.

Fig. 3 is that surface of roller is the structural representation of arc-shaped slot.

Fig. 4 is that surface of roller is the structural representation of Baltimore groove.

The specific embodiment

Following according to the accompanying drawing instance, the utility model is done further to detail:

The utility model as depicted in figs. 1 and 2, it includes roller 1 and roller 2, and roller 1 outer surface is provided with the dovetail groove more than two 3 that is round, and roller 2 outer surfaces are provided with the raised line 4 that contacts and cooperate with dovetail groove 3; When getting into rear roller, rove 5 advances drawing-off for the first time again when upper and lower pin arrival front roller is the roller 1 of the utility model, because the effect of roller 1 upper trapezoid groove 3 makes flat loose rove be able to polymerization to middle roller; The burr of periphery is forced and gathers in the dovetail groove 3, pushes drawing-offs through roller 2 outer raised lines 4, and most of fiber will wrap up end to end each other; Leave roller 1 through narrow bottom land and get into twisting area, because the effect of dovetail groove forms the triangle twisting area hardly; So after twisting, the smooth surface of yarn, " filoplume " is a large amount of to be reduced; Experimental test is more than 3 millimeters, and " filoplume " descends more than 50%, and the Wu Site strip dry CV value reduces more than 1 percentage point; Thickness joint cotton knot reduces significantly, powerful increasing.

Groove in the foregoing description can be the dovetail groove 3, also can be deep-slotted chip breaker 13, can also adopt Baltimore groove 23.

Claims

1. a roller roller closely spins, and includes roller and roller, it is characterized in that: said roller outer surface is provided with several grooves that are round, and said roller outer surface is provided with the round raised line that matches with said groove.

2. roller roller according to claim 1 closely spins, and it is characterized in that: said groove is a dovetail groove.

3. roller roller according to claim 1 closely spins, and it is characterized in that: said groove is an arc-shaped slot.

4. roller roller according to claim 1 closely spins, and it is characterized in that: said groove is a Baltimore groove.

5. closely spin according to claim 1 or 2 or 3 or 4 described roller rollers, it is characterized in that: said groove contacts with the surface of said raised line.
