Abstract
The utility model relates to a cylinder metal card clothing special for fining hemp fiber, which comprises a base portion (2) and pin-teeth (1) evenly distributed on the base portion (2), and the pin-teeth (1) employ double circular arc camber of low-angle double anterior angle and left and right high angle for allocation. The cylinder metal card clothing special for fine hemp fiber is extremely favorable for carding machine card to grip, card and transmit timely the fine hemp fiber, thereby avoiding twisting of the fine hemp fiber in process, and enabling quality of spinning products to achieve leading level.
Description
Technical field
The utility model belongs to the textile machine field of components, particularly relates to the special-purpose cylinder metal needle cloth of a kind of hemp that becomes more meticulous.
Background technology
Hemp is the natural fabric of excellent performance.Traditional hemp is come unstuck and wet spinning technology after adopting and spinning, and fiber is thicker, and spinnability is poor, becomes yarn count low, and product specification is lower.And the meticulous hemp that adopts advanced machining technology production can adopt the dry process spinning, becomes yarn count and quality to improve greatly, become more meticulous hemp can with cotton, wash with viscose glue etc. and produce a high a high proportion of high-quality blended yarn.
Chinese patent disclose the patent No. for the ZL02288496.3 denomination of invention be the special-purpose cylinder metal needle cloth of novel soybean azelon as shown in Figure 1, this card clothing comprise base portion 2 ' and be distributed on the pin tooth 1 of base portion 2 ' top ', it is characterized in that the two anterior angles of described pin tooth 1 ' employing and two circular arc camber configuration, anterior angle α on its pin tooth
1' be anterior angle α under 19～20 degree, the pin tooth
2' be 25 degree, the left circles arc surface β that cuts angle
1' be 45 degree, the right circles arc surface β that cuts angle
2' be 15 degree, the tooth pitch P ' of pin tooth is 1.47～1.53 millimeters, pin transverse tooth thickness degree a ' is 0.06～0.08 millimeter, thickness at root of tooth b ' is 0.3 millimeter, crown height h ' is 0.55 millimeter, pin tooth height overall H ' is 2.48～2.52 millimeters, the density of pin tooth be 728 tooth/square inches, described base portion 2 ' base portion thickness W ' be 0.58～0.62 millimeter, base portion height C ' is 1.2 millimeters.
Hemp is compared with soybean fiber owing to become more meticulous, and both are in surface state or physical property all has obvious difference, and there is groove on the surface of the hemp that becomes more meticulous, and bending rigidity is bigger, and proportion is bigger, and resilience is better; And that the soybean fiber fiber shows is smooth, and the fiber softening bending rigidity is little, fluffy light specific gravity, and few resilience of curling is poor.If directly adopt novel soybean azelon special-purpose metal card clothing that the hemp that becomes more meticulous is processed, it is insufficient to produce the branch comb, and the fibre migration degree is not high, is unfavorable for middling speed production, and yield and quality is lower, and fiber also has technical problems such as winding.
Summary of the invention
Technical problem to be solved in the utility model provides the special-purpose cylinder metal needle cloth of a kind of hemp that becomes more meticulous and divides comb insufficient in the prior art to solve, the defective that the fibre migration degree is not high.
Technical scheme
The utility model provides a kind of hemp that becomes more meticulous special-purpose cylinder metal needle cloth, include base portion 2 and be distributed on pin tooth 1 on the base portion 2, pin tooth 1 adopts two anterior angles of low-angle and the two circular arc cambers configurations of left and right sides wide-angle, and described base portion 2 height C are anterior angle α on 1.5 millimeters, described pin tooth
1Be 17.5～18.5 degree, anterior angle α under the pin tooth
2Be 20～24 degree, the left circles arc surface β that cuts angle
1Be 50 degree, the right circles arc surface β that cuts angle
2Be 16～18 degree, the tooth pitch P of pin tooth is 1.37～1.45 millimeters, and crown height h is 0.65 millimeter, and pin tooth height overall H is 2.66～2.79 millimeters.
The density of described pin tooth (2) is 427 tooth/square inches.
Beneficial effect
The utility model is because the pin tooth has adopted about two anterior angles of low-angle and wide-angle two circular arc camber configurations etc. to improve design, be very beneficial for of gripping, combing and the in time transfer of carding machine card clothing to the hemp that becomes more meticulous, avoided the becoming more meticulous wrapping phenomena of hemp work in-process makes the spinning yield and quality can reach good level.
