Abstract
The utility model discloses doffer card clothing of a carding machine suitable for short velvet fibers. The doffer card clothing comprises a card clothing base body; needle teeth are obliquely arranged on the card clothing base body; each needle tooth comprises a front tooth surface and a tooth back; the tooth back is in an outwards protruded arc shape; and the tooth density of the needle teeth on the card clothing base body is controlled to be 403 to 424 teeth per square inch. The doffer card clothing has the advantages that the tooth back of each needle tooth is set in the arch shape, so that the section width from top to bottom is increased, the strength of each needle tooth is increased, and the needle teeth are prevented from falling and being damaged by rolling; and the density of the needle teeth is increased, the distance between the adjacent needle teeth is reduced, deposition of the velvet fibers between the adjacent needle teeth is effectively reduced, a velvet net is conveniently peeled by a cutter, damage to the velvet fibers is reduced, and the quality of finished yarns is improved.
Description
Technical field
The utility model relates to the combing machine for fur in the wool textile industry, relates in particular to the card clothing on the doffer in the combing machine for fur.
Background technology
Special animal fiber such as yakwool, cashmere raw material; Have sliding glutinous, the good springiness of feel, moisture absorption, the moisture releasing performance is good, thermal property is good characteristic; Be fit to make spinning high-grade fabric lining; But after these fibers repeatedly divided comb through preliminary working, the suede fibre fineness was thin, fiber short, difference in length is big and fluffy.On worsted card, above-mentioned suede fiber is after the cylinder combing, and the pin tooth of the last card clothing of doffer is constantly grabbed suede and formed the suede net and migrate out cylinder, by die the doffer is gone up the suede net that forms again and peels, shifts and form the suede bar.Doff clothing on traditional doffer, as shown in Figure 1, its structure comprises: card clothing matrix 1; Card clothing matrix 1 is provided with pin tooth 2; Described pin tooth 2 is the inclination straight-tooth, and promptly the preceding flank of tooth of pin tooth and rear flank are tiltedly straight plane, and the incline direction of pin tooth is opposite with doffer's direction of rotation.The height of the pin tooth 2 of the doff clothing of said structure is high, intensity is low, tooth density is little, so when using the doff clothing of said structure to shift short velvet fiber, the pin tooth takes place easily lodge even roll bad, the service life of doff clothing is not long; Again because ox suede fiber and cashmere fiber are short; The tooth density of pin tooth 2 is little---and the tooth density of conventional needle tooth 2 is 200-300 tooth/square inches; Spacing between the adjacent needles tooth is bigger, and short velvet fiber is deposited on the bottom position between the adjacent needles tooth 2 easily, causes die to be difficult to strip; Formation is scored a goal or the slivering difficulty, causes the quality of finished product yarn low.Therefore generally believe that staple fibre suedes such as yakwool can't slivering on worsted card.
The utility model content
The purpose of the utility model is: provide a kind of intensity high, little and be not easy to produce a kind of combing machine for fur doff clothing that is applicable to short velvet fiber of deposition to fibre damage.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of combing machine for fur doff clothing that is applicable to short velvet fiber; Comprise: card clothing matrix, card clothing matrix tilt and are provided with the pin tooth, the flank of tooth and rear flank before the pin tooth comprises; Described rear flank is the arcuate shape of outwards protruding, and the tooth density of described card clothing matrix upper pin gear is controlled at 403-424 tooth/square inches.
Further, preceding described a kind of combing machine for fur doff clothing that is applicable to short velvet fiber, wherein, described pin flank is provided with the band of depression.
The utility model has the advantages that: the rear flank of pin tooth is arranged to arcuate shape, has strengthened pin tooth cross-sectional width from top to bottom like this, thereby increased the intensity of pin tooth, the situation generation of having avoided the lodging of pin tooth and having rolled bad; Reduced the adjacent needles space width, pin tooth density has effectively reduced the deposition of suede fiber between the adjacent needles tooth, greatly facilitates die to the stripping of suede net, and has also reduced the damage to the suede fiber simultaneously, has improved the quality of finished product yarn.
Description of drawings
Fig. 1 is the structural representation of the doff clothing described in the background technology.
Fig. 2 is the described a kind of structural representation that is applicable to the combing machine for fur doff clothing of short velvet fiber of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to specify.
As shown in Figure 2, a kind of combing machine for fur doff clothing that is applicable to short velvet fiber comprises: card clothing matrix 1, card clothing matrix 1 tilt and evenly are provided with pin tooth 2, and the flank of tooth 22 and rear flank 21 before pin tooth 2 comprises, described rear flank 21 are the arcuate shape of outwards protruding.Evenly be provided with four roads depression band 3 in the side of pin tooth 2.The incline direction of described pin tooth 2 is opposite with doffer's direction of rotation; The height of pin tooth 2 is suitably 2.6-2.8 millimeters; Space width is 1.9-2.0 millimeters, and pin tooth density is suitable to be controlled at 403-424 tooth/square inches, and the thickness of card clothing matrix 1 is suitably 0.8 millimeter.Owing to the rear flank 21 of pin tooth 2 is arranged to the outwards arcuate shape of protrusion, has strengthened pin tooth 2 section thickness from top to bottom like this, thereby increased the intensity of pin tooth 2; The situation of having avoided 2 lodging of doff clothing upper pin gear and having rolled bad takes place; Prolonged the service life of card clothing,, reduced the spacing of adjacent needles tooth 2 with the density of hour hands tooth 2; Effectively reduced the deposition of suede fiber between the adjacent needles tooth 2; Greatly facilitate stripping of stripping-comb and obtain neat and well spaced suede net, reduced damage simultaneously, improved the quality of finished product yarn the suede fiber.Owing to be provided with the band 3 of four roads depression on the surface of pin tooth 2, effectively increased the grasping force between pin tooth 2 and the suede fiber, further reduced the suede that falls, improved row yielding.
Claims (2)
1. combing machine for fur doff clothing that is applicable to short velvet fiber; Comprise: the card clothing matrix; The card clothing matrix tilts and is provided with the pin tooth; The flank of tooth and rear flank before the pin tooth comprises is characterized in that: the arcuate shape of described rear flank for outwards protruding, the tooth density of described card clothing matrix upper pin gear is controlled at 403-424 tooth/square inches.
2. a kind of combing machine for fur doff clothing that is applicable to short velvet fiber according to claim 1, it is characterized in that: described pin flank is provided with the band of depression.
