Abstract
The utility model relates to a special cutter head of a cutting-off machine for imitation velvet polyester ultra-short fibers. The special cutter head mainly comprises a cutter head body, a pressing wheel, positioning columns, and fixed cutter holders which are arranged on the cutter head body. Cutting blades are installed in the fixed blade holders. Fifteen to twenty-five cutting blades form a group and are installed in blade grooves in one fixed blade holder. The spacing between every two blades is 3-12mm. The positioning columns divide the cutter head into 8-15 equal-arc sections. Since the spacing between every two cutting blades is reduced to 3-12mm, when the imitation velvet polyester ultra-short fibers are cut off, the required length of the ultra-short fibers is less than 15mm.
Description
Technical field
The utility model relates to the device that fibre bundle cuts off in the production equipment of chemical fibre industry, relates in particular to a kind of special-purpose cutting machine cutterhead of imitative goose down terylene superbhort fiber of Cutting cutter being improved renewal.
Background technology
Along with the fast development of chemical fibre industry and improving constantly of the market demand, people are more and more higher to the requirement of product quality.Cut-out, packing are the last two procedures in the staple fibre production process.For reaching imitative goose down effect, the terylene superbhort fiber requires to have accurate shearing length, guarantees that shearing length is between the 3-12mm.And for having the continuously production line of operation now, because operating load is large, output is high, conventional ultrashort Cutting cutter can't satisfy conventional cut-off velocity, distortion, breaking often can occur or even super, over-length fibre occur in production.Cutting machine adopts wheel pressure type cutter blades mostly at present, the operation principle of this cutting machine is: many cutting knife is installed on the cutterhead, form a circle with certain rule, cutting edge outwardly, cutterhead has cutting machine power transmission shaft driven rotary, from the chemical fibre tow of flow production line constantly around to dish, after overstocking, multilayer forms certain thickness, after the chemical fibre tow on the cutterhead reaches certain thickness, tow just is subject to being arranged on the pressure of the pinch roller of cutterhead one side, at this moment, again on the cutterhead around the chemical fibre tow, the internal layer of original tow on cutterhead just can be cut off by cutting knife, so that the thickness of the tow on the cutterhead remains unchanged substantially, reach continuous cutting-off chemical fibre tow, the purpose of assurance device stable operation, but the cutterhead cutting knife setting space of above-mentioned cutting machine is large, be difficult to finish imitative goose down terylene superbhort fiber required＜staple fiber ppd of 15mm; Secondly vertical cutting knife easily causes the generation of edge of a knife passivation and spring lip reflex when cut staple, super, over-length fibre often occur; The cutter blades of chemical fibre cutting machine adopts alloy steel material to make again, because low, the rigidity of its hardness and wearing no resistance, when the superbhort fiber feed quantity increased, because the blade amount is many, the tow resistance increased, breaking, distortion easily appear, particularly when the angle design of blade was unreasonable, the cutting angle was large, causes cutting resistance large, quick abrasion, service life short deficiency.
The utility model content
The purpose of this utility model is to solve above-mentioned problems of the prior art, provides a kind of blade space to be reduced to 3-12mm, has met the length requirement＜15mm of imitative goose down superbhort fiber; The blade that the nose angle that is obliquely installed has been avoided cutter easily blunt, spring lip reflex generation simultaneously cutter blades adopt whole superhard material or blade to execute again to cover superhard coating made, increase the special-purpose cutting machine cutterhead of imitative goose down terylene superbhort fiber of hardness, rigidity and ABRASION RESISTANCE.
The technical scheme that its technical problem that solves the utility model adopts is: the special-purpose cutting machine cutterhead of a kind of imitative goose down terylene superbhort fiber, it mainly comprises cutter head and pinch roller, with the stationary knife seat that is located on the cutter head, in the stationary knife seat cutter blades is installed, synthetic one group of every 15-25 sheet cutoff tool, be installed in the cutter groove of a stationary knife seat inside, the spacing between the two adjacent blades is 3-12mm, and described stationary knife seat is divided into cutterhead at the radian intervals such as 8-15 group.
The beneficial effects of the utility model are: the utility model passes through the hypotelorism between the cutoff tool between the 3-12mm, so that when cutting off imitative goose down terylene superbhort fiber, reach the Len req＜15mm of superbhort fiber; Simultaneously cutter blades adopts whole superhard material or blade to execute to cover superhard coating made again, has increased its hardness, rigidity and ABRASION RESISTANCE, and cutter avoids occurring distortion or breaking in the cutting-off process.
As preferably, the blade of described blade and horizontal direction are 10-20 degree angle, being obliquely installed of nose angle, and the blade of having avoided cutter is the generation of blunt, spring lip reflex easily.
Further, it is made that the blade of described blade and cutter hub system adopts whole superhard material or blade to execute to cover superhard coating again, increased hardness, rigidity and the ABRASION RESISTANCE of cutter.
Compared with prior art, advantage of the present utility model is as follows: 1, the blade space in the Cutting cutter is reduced to 3-12mm, has met the requirement of the length＜15mm of imitative goose down terylene superbhort fiber; 2, cutter adopts and to be obliquely installed, and the blade of having avoided cutter is the defective such as blunt, the mouth that jumps easily, has effectively improved cutting-tool's used life; 3, the blade of blade and cutter hub system adopts whole superhard material or blade to execute to cover superhard coating made again, has increased hardness, rigidity and the ABRASION RESISTANCE of cutter, guarantees to adopt conventional speeds to cut off and satisfies normal production.

Shown in the figure: 1, cutter head, 2, pinch roller, 3, the stationary knife seat, 4, cutter blades.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As Figure 1-3, the utility model is the special-purpose cutting machine cutterhead of a kind of imitative goose down terylene superbhort fiber, it mainly comprises cutter head 1 and pinch roller 2, with the stationary knife seat 3 that is located on the cutter head, cutter blades 4 is installed in the stationary knife seat, and every 15-25 sheet cutoff tool 4 synthesizes one group, is installed in the cutter groove of a stationary knife seat inside, spacing between the two adjacent blades is 3-12mm, and described stationary knife seat is divided into cutterhead at the radian intervals such as 8-15 group.By with the hypotelorism between the cutoff tool between the 3-12mm so that when cutting off imitative goose down superbhort fiber, the Len req that reaches superbhort fiber is＜15mm; It is made that the blade of described blade and cutter hub system adopts whole superhard material or blade to execute to cover superhard coating again, increased hardness, rigidity and the ABRASION RESISTANCE of cutter; Wherein the blade of blade and horizontal direction are 10-20 degree angle, being obliquely installed of nose angle, and the blade of having avoided cutter is the generation of blunt, spring lip reflex easily.
Above-described embodiment is a kind of better scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
