马口铁制罐新设备—CAN-O-MAT系统多功能组合机

马口铁罐的分切、翻边、缩颈、滚筋和封口等制罐工序,历来都是由单机来完成的,即每一台机器只能完成上述工序中的一道工序。而要组成制罐自动生产线,则必须用专用的提升设备及输送装置,将各台单机连接组合。由于各单机运行不同步,且罐身在运行过程中易发生卡阻堵塞现象,使某一单机不得不暂时停机而影响整条生产线的连续运转。为此,各单机之间的罐身输送     

旋压式翻边机

在食品、日用化工等制罐行业中,有一道重要的工序——翻边,它是封罐工序的上一道工序。目前国内外普遍采用的是往复撞击式翻边和滚压式翻边,前者动作较简单,主要用于锡焊罐身的翻边,但所需的力和功率较大;后者主要用于印铁制罐行业,其动作、机构较复杂,所需的力和功率较小。但也有缺点,即由于结构限制,其翻边模小于罐身内径,结果也不大理想,翻出来的边不     

12×4J轮辐斜冲模翻边变形分析

利用斜冲模对12×4J轮辐进行翻边时,将变形区看做是平面应力状态,探讨了翻边高度、初始孔径及斜冲模角对翻边变形区径向应变和轴向应变的影响,对12×4J轮辐翻边不同斜冲模角下的冲压力变化规律进行了计算.结果表明,影响变薄的因素除斜冲角以外,还与其周向应变有关.厚向应变和径向应变随斜冲角增大而增大,但翻边力却正好相反,综合考虑,斜冲角取α=30°～35°比较理想.

A relationship between dry-relaxed warp-knitted fabric structure and curling distance

This study provides us information about relationship between curling and knitted structure and density of two-guide bar warp-knitted fabrics. Five standard warp-knitted fabrics are produced with three densities (Tricot, Locknit, three-needle Satin, Reveres Locknit and three-needle Sharkskin). Certain cut lengths of sample fabrics in both wale and course direction are analyzed through image processing to define curling value. A mechanical model, a function of fabric structure and yarn parameters, is also suggested to predict the curling force. The results of experimental and theoretical results show a greater curling value for course-wise cut in comparison to that of wale-wise in all warp-knitted structures and densities. The lowest curling value is found for three-needle Sharkskin structure in both directions and all densities.

Investigation into the curling behavior of single jersey weft-knitted fabrics and its prediction using neural network model

This research investigates the effect of fiber, yarn, and fabric parameters on curling phenomenon of single jersey weft-knitted fabrics which is interpreted to have curling surface in both course and wale direction. Taguchi’s experimental design is used to estimate the optimum process conditions and to examine the individual effects of all controllable factors on curling one by one. The controllable factors are blending ratio of polyester to cotton fiber, yarn twist and count, fabric structure, knit density, and relaxation time. Results show that fabric structure and knit density have the most dominant effect on the fabric curling. The optimum conditions of minimum curling values were also determined. Finally, the curling surface in course and wale direction as a two features of curling phenomenon was predicted using artificial neural network which selects scale conjugate gradient learning algorithm based on process parameters of single jersey weft-knitted fabrics. Our findings confirm the good capability of artificial neural network algorithm to predict these features.

A new approach to de‐curling force of single jersey weft‐knitted fabric

In this work, the curling behavior of cotton single jersey weft‐knitted fabric was studied using a new non‐destructive test method. Eighteen series of dry‐relaxed weft‐knitted fabric samples were produced with three different yarn twist levels (724.5 tpm, 807 tpm, and 890 tpm), two yarn twist directions (Z and S), and three different loop lengths (2.7 mm, 2.85 mm, and 3.2 mm). Curling behavior was characterized in terms of curling distance (CD), de‐curling force, and de‐curling energy. The results show that weft‐knitted fabric samples with a lower loop length and higher yarn twist level exhibited higher de‐curling force and de‐curling energy. It is indicated that the de‐curling force of weft‐knitted fabric samples produced from the Z‐twist cotton ring‐spun yarn is higher than that of the samples produced from the S‐twist cotton ring‐spun yarn. The regression analysis results also illustrate that de‐curling force and de‐curling energy are non‐linearly correlated with edge CD, and variation trends follow polynomial equations. The result of this research suggests that the curling behavior of weft‐knitted fabric can be predicted in terms of de‐curling properties.     

组织结构对涤纶经编织物卷边性的影响

为减少织物卷边对后道工序带来的影响,对各把梳栉的组织结构配置以及牵拉密度的选择进行了探讨。以55.5 dtex 24 f涤纶全牵伸丝(FDY)为原料,生产出7种不同组织和4种不同牵拉密度的两梳经编织物,对其卷边量进行测试,并结合显微镜下的线圈图进行分析。结果表明：随着牵拉密度的增大,经编织物横、纵向卷边量均不断减小,其中牵拉密度对横向卷边的影响要明显大于纵向卷边;两梳同向编织的织物横向卷边性要明显好于反向编织;当前梳组织不变,增加后梳延展线长度时,织物的横、纵向卷边量均不断减少,尤其是横向卷边量下降明显;而当后梳组织不变,增加前梳延展线长度时,织物的横、纵向卷边量均不断增加。
