高產(chǎn)高速 自動化 信息化
目前,紡織企業(yè)正處在轉(zhuǎn)型升級的重要時期。面對勞動力資本上漲、原料價格增長、匯率波動等現(xiàn)狀,紡織企業(yè)通過自動化、連續(xù)化、信息化設備,克服了生產(chǎn)困境,實現(xiàn)了減少用工、提高生產(chǎn)率、穩(wěn)定產(chǎn)品質(zhì)量的目標。
前紡設備大卷裝為高產(chǎn)創(chuàng)造了條件。如梳棉機幅寬加寬,條筒加大;并條機、精梳機等條筒容量也不斷增大。各種設備的連續(xù)化為高產(chǎn)奠定了基礎。如,清梳聯(lián)的普遍使用,精梳棉卷自動輸送、生頭,粗紗、細紗、絡筒工序的自動聯(lián)接,筒紗自動運輸、包裝,在線監(jiān)控、管理等等。基于互聯(lián)網(wǎng)平臺的監(jiān)控管理技術,在線監(jiān)控管理可以延伸至所有設備運行狀態(tài)、產(chǎn)品各環(huán)節(jié)質(zhì)量、車間環(huán)境、能源消耗等各個環(huán)節(jié)。
High speed, high output, automation, information
At present, the textile enterprises are in a critical period of transformation and upgrading. In face of rising labor costs and raw material price fluctuations, textile enterprises have been successful in reducing labor costs, improving productivity, and stabilizing product quality based on automatic and continuous equipment.
Large package of spinning preparation equipment created conditions for high productivity, such as broader width and enlarged sliver cans of card as well as growing increased sliver can capacity of drawing machines and combing machines. The continuity of various equipment laid the foundation for high output. For example, the common use of blowing-carding, automatic connection of feeding of combed lap, roving yarn, spun yarn, and winding process, automatic transportation and packaging, on-line monitoring, and management of bobbin yarn. Internet-based monitoring and management technology platform can be extended to all sections, including the equipment running status, product quality, the workshop environment, energy consumption and so on.
金輪針布 三款針布滿足高速高產(chǎn)需求
GERON Card Clothing: Three products for high speed and high production
高產(chǎn)錫林針布
雙齒設計:矮齒在初始階段具有一定的握持分梳能力,在正常分梳時又能托持纖維,可以使纖維維持在齒尖,有效防止纖維下滑;雙齒組合,能間接地提高錫林針布密度,提升分梳效果,因而在工藝條件基本不變的情況下,可以實現(xiàn)提高產(chǎn)量同時保證質(zhì)量。
平頂、大前角設計:大齒尖采用“平頂”設計思路,即保證大部分纖維停留在齒尖部位,又有效防止纖維下滑,采用大前角設計可以有效地控制纖維,增加分梳作用效果。
高矮齒設計:可以實現(xiàn)雙重托持纖維,并對工作面采取圓弧工作面設計,能夠提高纖維的“一次性分梳效果”,由于托持作用的增強,可以提升纖維和蓋板、道夫的接觸長度,增加作用齒數(shù), 有利于纖維的分梳、混合和轉(zhuǎn)移等作用, 提高纖維的梳理度和均混效果。
專利號:高密梳棉金屬針布ZL201110165025.3。
強轉(zhuǎn)移針布
雙側(cè)橫紋設計:傳統(tǒng)的橫紋針布,是在齒部一側(cè)面帶有橫紋,另一面為光面,主要是提高針布的握持能力,提高纖維的轉(zhuǎn)移性能,但在高速、強轉(zhuǎn)移的條件下,該種設計還存在不足,握持能力弱,造成轉(zhuǎn)移不足,甚至掉網(wǎng)以及飛花多現(xiàn)象,影響梳理效果;而雙面橫紋針布彌補其不足,是在針布的雙面設計橫紋,形成雙面橫紋特殊結(jié)構(gòu),增強針布對纖維控制能力,改善針布抓棉不足、掉網(wǎng)、飛花多等現(xiàn)象,提高針布的梳理效果。
工作面帶槽設計:對于握持能力弱,抱合力差的纖維,轉(zhuǎn)移性能差,特別是錫林和道夫之間轉(zhuǎn)移。而影響道夫轉(zhuǎn)移率首先是由道夫針布的規(guī)格參數(shù)(如工作角、齒密、針高)、表面狀態(tài),其次是針布的齒型結(jié)構(gòu)設計,最后是工藝速度。因而在設計道夫齒型結(jié)構(gòu)時,在道夫的工作面采用開槽設計,增加對纖維的控制能力,提高轉(zhuǎn)移率,改善棉網(wǎng)質(zhì)量。
專利號:一種用于紡織纖維梳理用的梳理機用齒條ZL201120462392.5。
寬幅蓋板針布
為了提高梳棉機臺時產(chǎn)量,增加分梳效果,因而梳棉機的寬度從常規(guī)的1000mm增加到1200mm或1500cm,但在寬度增加后容易引起異常,如變形,工藝隔距滿足不了要求,使用過程中易接針等;
首先,通過對寬幅蓋板針布參數(shù)重新設計,如針高、工作角、植針組織、排列方式等優(yōu)化設計,改變傳統(tǒng)的設計理念,避免因幅寬存在不足而產(chǎn)生的異常;其次,改變磨針工藝,對針布平整度、側(cè)磨細度、錐狀對稱要求和針尖刀口形狀重新確定要求和標準;寬幅蓋板針布材料選用進口特高耐磨合金鋼絲及先進技術的特制鋼絲,能提高并確保針布梳理的抗變形能力;采用特制C型底布,能加強和改善底布對鋼針的握持能力,同時采用高性能的合金鋁帶和鋼帶,提高邊夾包覆蓋板針布平直度。endprint
High production cylinder wire
Duo-tooth design: The lower tooth has certain ability to grip and card in the initial stage, and can hold the fibers during normal carding, which can keep the fibers at the tooth tips and effectively prevent the fibers from sliding down. The duo-tooth combination can indirectly increase cylinder density and improve carding effect, so as to increase output while ensuring quality based on the basically unchanged process conditions;
Flat top and large rake angle design: The big tooth tip adopts “flat top” design, which cannot only guarantee most of the fiber to stay in the tooth tip position, but also effectively prevent the fiber from falling. The large rake angle design can effectively control the fiber, improving the carding effect;
High-low tooth design: Double support of fibers can be achieved, and the working surface is designed in circular arc, which cannot only improve the“one-time carding effect”, but also increase the contact length between fiber and the card flat and doff due to the enhanced backing. As a result, it is conducive to fiber carding, mixing and transfer, improving fiber carding degree and mixing effect.
Patent No .: ZL201110165025.3
Transfer wire
Bilateral cross-striation: The traditional cross-striation wire is featured with stripes on one side of the teeth and smooth on the other side, mainly to improve the gripping ability of the card clothing and improve the fiber transfer performance. However, in the condition of high speed and strong transfer, the design is still inadequate, such as weak gripping capacity, which will result in insufficient transfer, or even drop from the web and more card fly, affecting the carding effect. The double-sided cross-striation wire can make up for its deficiencies because of the special double-sided cross-striation structure, which enhances its ability to control the fiber and improves carding effect.
Grooved working surface: The fibers of weak gripping and cohesion see poor transfer performance, in particular, the transfer between cylinder and doff. The doff transfer rate is primarily impacted by the specification parameters (such as working angle, tooth density, and needle height) as well as the surface state, followed by the needle structure design, and finally the process speed. Therefore, in the design of the tooth structure of doff, its working surface is grooved, so as to increase the control to fiber, improve the transfer rate and improve the web quality.endprint
