Abstract
The distance between the drafting head bases A is equal, the two drafting head bases B are respectively arranged at the outer sides of the drafting head bases A at the two ends, the distance between the drafting head base B and the adjacent drafting head base A is smaller than the distance between the two adjacent drafting head bases A, the difference is 5mm-20mm, and each drafting head base A and each drafting head base B are correspondingly movably connected with one drafting head. The utility model can effectively improve the problem of low gram weight at two ends of the lapping machine and reduce the trimming; the uniformity of the two ends and the middle width direction of the non-woven fabric is improved; the fiber quantity of fiber nets at two ends is increased by adjusting the distance between the drawing heads B at two ends of the base fixing plate of the drawing head, so that the gram weight of the fiber nets at two ends is increased, and the product quality is improved.
Description
Technical Field
The utility model discloses use in the non-woven field of gluing.
Background
The spunbonded nonwoven fabric is used as a main base material in the industries of geotechnics, waterproofing, filtration, home decoration and the like and is an indispensable industrial fabric, and the most important physical property index for measuring the quality of the spunbonded nonwoven fabric is the uniformity of the fabric surface, and the uniformity of the fabric surface directly influences the quality indexes such as the strength, the elongation and the uniformity of thermal shrinkage of a product. At present, a spinning assembly of a spinning box adopts spinnerets with the same hole number in the width direction, two rows of spinning are arranged in a staggered mode, and are cooled by side air blowing, then drawn by pipe-type airflow, the fiber web amount distributed in the width direction of a lapping machine is different after yarn swinging, the fiber web amount close to the middle is large, the product gram weight at two sides is lower than the product gram weight at the middle due to the fact that the fiber web amount close to the two sides is small in the staggered mode, and therefore the uniformity of the two ends and the width direction of the middle is affected.
It has the following disadvantages: the distance between the drafting heads is the same, the number of fibers in each drafting head is the same, and the tubular drafting production process has defects and defects in the aspect of cloth cover uniformity.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an interval of head is drawn at both ends to accessible adjustment to make the fibre web volume of both ends cloth cover adjustable, and then increase the gram weight of both ends fibre web, improve the draw gear of the first interval is drawn at the adjustable width both ends of cloth cover homogeneity.
The utility model discloses mainly include draft ware upper bracket, draft ware lower bracket, draft head base fixed plate, draft head base A, draft head base B, draft head, draft pipe, coupling hose, lower guide plate and go up the guide plate.
The upper fixing frame and the lower fixing frame of the drafting device are fixedly connected, the drafting head base fixing plate is arranged on the upper fixing frame of the drafting device, and the plurality of drafting head bases A and the two drafting head bases B form a group of drafting head bases. The distances among the plurality of drafting head bases A are equal, and the two drafting head bases B are respectively arranged at the outer sides of the drafting head bases A at the two ends. The distance between the drawing head base B and the adjacent drawing head base A is smaller than that between the two adjacent drawing head bases A, and the difference is 5mm-20 mm. The two groups are arranged on the fixed plate of the drafting head base, and the two groups of drafting head bases are arranged in a staggered way. Each drafting head base A and each drafting head base B are movably connected with a drafting head correspondingly, the lower opening of each drafting head is connected with a drafting pipe correspondingly in a threaded manner, the side surface of each drafting head is connected with a connecting hose, and the side wall of each drafting head is provided with an air inlet. The side of the lower fixing frame of the drafting device is provided with a lower guide plate, the side of the upper fixing frame of the drafting device is provided with an upper guide plate, and the upper end of the drafting head extends to the outside of the upper guide plate.
The utility model discloses when using, the fibre web is from spinning subassembly blowout, draft to the draft head of draft ware through side-blown cooling device, to pendulum silk ware net formation and lapping machine again, the process of spinning net formation has just been accomplished, reduce the distance between both sides draft head B and the adjacent draft head, reduced 5mm-20mm on original basis, concrete project still need confirm according to the demand, and then the lapping interval of adjustment both ends silk bundle, superimposed possibility is higher when the silk bundle is put down through pendulum silk ware, thereby increase the fibre volume of both ends fibre web, increase the gram weight of both ends fibre web, improve the homogeneity of width direction cloth cover.
Compared with the prior art, the utility model have following advantage:
1. the problem of low gram weight at two ends of the lapping machine can be effectively solved, and the edge cutting is reduced;
2. the uniformity of the two ends and the middle width direction of the non-woven fabric is improved;
3. the fiber quantity of fiber nets at two ends is increased by adjusting the distance between the drawing heads B at two ends of the base fixing plate of the drawing head, so that the gram weight of the fiber nets at two ends is increased, and the product quality is improved.
