Memminger-IRO: 用于无缝针织机的改进型导纱器

为了充分发挥无缝针织机的最佳功能,织造出高质量的成片,需要针对不同类型的纱线采用不同功能的导纱器:如MSF、EFS800和EFS900型导纱器都适合于编织无缝内衣的领部和身体主干部分,但他们又都具有不同功能,EFS900型导纱器带有集成的纱线回退功能,而EFS800型导纱器还可以调节纱线张力,以上三种导纱器首次在意大利维罗纳市召开的FAST 2005上展出,德国Memminger-IRO公司已对这些装置进一步做了改进,对导纱器结构进行了优化.     

筒纱万能导纱器装置的设计及应用

1筒子纱（宝塔纱）底纱退绕效率低下的影响及原因分析 筒子纱（宝塔纱）退绕时,遇锥形纱管顶端的边沿毛刺,极易发生退绕断头,尤其超细号筒子纱退绕时断头甚至会达100%,不仅影响整经工序、并纱工序、织造工序（喷气纬）的效率,同时造成大量的筒脚退绕回丝,更严重是因超细号底纱接头困难     

FA721-75A型捻线机导纱杆的更新

我公司现用16台FA72175A型捻线机,捻线机导纱杆采用直径4mm普通碳素圆钢制造,表面电镀处理。纱线在经过导纱杆时,由于横动机构作用,在导纱杆表面形成一定的动程,使用过程中,纱线张力非常大,纱线与导纱杆长时间摩擦造成导纱杆表面出现沟痕,纱线无法在正常的动程内经过导纱杆,只能受限于沟痕内通过,使纱线易出现毛羽,强力降低,强力CV值增大,纱线质量受到影响。为此,我们重新设计了导纱杆,如图1所示。采用导纱支架上镶导丝器,纱线在导丝器内通过,具体作法是:(1)支架采用1.8mm厚冷铁板制成,在支架上开一个宽9.5mm、深9.5mm的槽,将导丝器镶在槽…

粗纱退绕张力的电测及导纱杆水平位置的选择

能控制卷绕张力的digitens装置

据瑞士SSM公司介绍,为获得均匀一致的卷装,很重要的一个方面是在任意卷装直径的情况下确保有均匀的卷绕张力.现有的大多数络筒机有可能仅对卷绕张力进行限制,或有的根本就对卷绕张力没有控制.卷绕过程中的张力失控将直接导致卷装的密度发生变化,使筒纱染色不匀,或者使最终使用的卷装密度不均匀.喂入卷装最常见的纱线张力变化来自于喂入卷装直径的变化、喂入卷装导纱器的往复运动以及喂入卷装纱层间的张力弱环.

Predicting morbidity and mortality using automated milk feeders: A scoping review

Automated milk feeders (AMF) are computerized systems that provide producers with a tool that can be used to more efficiently raise dairy calves and allow for easier implementation of a high plane of nutrition during the milk feeding phase. Automated milk feeders also have the ability to track individualized behavioral data, such as milk consumption, drinking speed, and the number of rewarded and unrewarded visits to the feeder, that could potentially be used to predict disease development. The objective of this scoping review was to characterize the body of literature investigating the use of AMF data to predict morbidity and mortality in dairy calves during the preweaning stage. This review lists the parameters that have been examined for associations with disease in calves and identify discrepancies found in the literature. Five databases and relevant conference proceedings were searched. Eligible studies focused on the use of behavioral parameters measured by AMF to predict morbidity or mortality in preweaned dairy calves. Two reviewers independently screened titles and abstracts from 6,675 records identified during the literature search. After title and abstract screening, 382 studies were included and then assessed at the full-text level. Of these, 56 studies fed calves using an AMF and provided some measure of morbidity or mortality. Thirteen examined AMF parameters for associations with morbidity or mortality. The studies were completed in North America (n = 6), Europe (n = 6), and New Zealand (n = 1). The studies varied in sample size, ranging from 30 to 1,052 calves with a median of 100 calves. All 13 studies included enteric disease as an outcome and 11 studies evaluated respiratory disease. Of the studies measuring enteric disease, 8 provided disease definitions (n = 8/13, 61.2%); however, for respiratory disease, only 5 provided a disease definition (n = 5/11, 45.5%). Disease definitions and thresholds varied greatly between studies, with 10 using some form of health scoring. When evaluating feeding metrics as indicators of disease, all 13 studies investigated milk consumption and 6 and 7 studies investigated drinking speed and number of rewarded and unrewarded visits, respectively. Overall, this scoping review identified that daily milk consumption, drinking speed, and rewarded and unrewarded visits may provide insight into early disease detection in preweaned dairy calves. However, the disparity in reporting of study designs and results between included studies made comparisons challenging. In addition, to aid with the interpretation of studies, standardized disease outcomes should be used to improve the utility of this primary research.

Impacts of Storicide II on internal feeders of Brown rice

Protectants applied to grain can reduce damage caused by insect feeding during storage. Although these protectants are effective against many external feeders, they may also reduce damage caused by internal feeders as they often interact with the exterior surface of the grain during their larval or adult stages to feed or oviposit. For this study, we investigated impacts of Storicide® II applied to brown rice on three different internal feeders: Rhyzopertha dominica (Fauvel), Sitophilus oryzae (L.), and Sitotroga cerealella (Olivier). We also investigated the effects of this protectant at three different temperatures and when it was combined with different percentages of untreated brown rice. Time-series clustering was also performed to determine whether treatments caused disruptions to the timing of progeny emergence. Overall, R. dominica was the most susceptible as mortality and knockdown were observed in mixtures containing 10% treated brown rice. In contrast, S. cerealella was the least susceptible as mixtures containing at least 50–75% treated brown rice were required to reduce progeny production. However, lowering the temperature to 22 °C did reduce the amount of treated brown rice required to reduce progeny emergence and also reduced the number of progeny that emerged synchronously, which would likely reduce mating and reduce population levels over time. Similar effects on progeny were observed for S. oryzae and R. dominica. Overall, these findings suggest that Storicide II can reduce population levels of internal feeders and that combining this protectant with cooler temperatures can provide additional protection.     

Short communication: Identification of diseased calves by use of data from automatic milk feeders

Housing calves in large groups is associated with a higher risk of respiratory disease and with increased difficulties in identifying diseased animals compared with single housing. The aim of the present study was to investigate the effect of clinical disease on some behaviors recorded by automatic milk feeders in pre-weaned dairy calves. The experiment included 27 calves from a Danish research farm and 41 calves from a Swedish research farm. The calves were fed restrictively from a computer-controlled milk feeder, and all calves were subjected to daily clinical examinations for 3 to 26 d, with information gathered on general condition, nasal discharge, lung auscultation findings, coughing, signs of dehydration, naval status, rectal temperature, fecal consistency, and presence of chin abscess, arthritis, umbilical hernia, poor body condition, and poor hair coat. Calves suffering from diarrhea, respiratory disease, fever, or unspecific decreased general condition for more than 2 d were considered to be diseased and were declared to have recovered when they had been free of clinical signs of the disease for at least 2 d. The effects of clinical status (healthy, diseased) on the number of rewarded and unrewarded visits to the calf feeder and drinking rate, respectively, were analyzed by variance component analysis using a mixed model. Milk consumption on diseased and nondiseased days within calves was compared using a Wilcoxon signed rank test. In total, 53 of the calves were diagnosed as diseased during the study period. All cases of diseases were mild and were associated with an unaffected or only mildly affected general condition. Diarrhea was diagnosed in 51 calves, 6 of which also had respiratory disease. In 2 calves, respiratory disease was the only diagnosis. Eleven calves had an unspecific decreased general condition. The number of unrewarded visits was significantly reduced when calves were diseased. In Swedish calves, there was also a tendency for rewarded visits to be reduced during diseased days. Drinking rate and number of rewarded visits increased with increasing age. No effect of clinical status on milk consumption was detected. The number of unrewarded visits was the most sensitive of the 4 feeding behaviors monitored to indicate clinical disease in calves fed restricted milk volumes.
