Process of processing the POY yarn into DTY yarn: POY original yarn - wire cutter - first roller - head rod - stagnation device - variant hot box - cooling plate - false twister - Second Roller - Shaped Hot Box - (Network Mouth) - Third Roll - Oiling Roller - Winding Roller - Winding - Graded Inspection - Packaging

 

原丝筒子架(Raw silk creel)

 

一般置于主机两侧,多为门式支架。主要作用为放置原丝筒子,一般每锭位放置两个丝筒,其中一个在使用,另一个为备用。同时在丝架上还装有导丝管,以供丝条分别导向喂入罗拉。

Usually placed on both sides of the mainframe, mostly door brackets. The main function is to place the original wire package. Generally, two wire packages are placed per spindle, one of which is in use and the other is reserved. At the same time, a wire guide tube is also arranged on the wire frame, so that the wire rods are respectively guided to the feeding roller.

 

第一罗拉(喂丝罗拉)/First roller (feeding roller)

 

喂丝罗拉有皮圈式和皮辊式两类。皮圈式中因皮圈与主动辊接触面大,可减少主动辊轴承磨损,在上、中、下喂丝装置的入口处装有慢速往复的移丝器。皮辊式喂入罗拉耐磨,但握持力不足,可采用在辊上多绕几圈的办法来弥补。

The feeding roller has two types of apron and leather rollers. In the apron type, the contact surface of the apron and the driving roller is large, which can reduce the wear of the driving roller bearing, and a slow reciprocating wire shifter is arranged at the entrance of the upper, middle and lower feeding devices. The roller-type feed roller is wear-resistant, but the grip is insufficient, and it can be compensated by a few turns on the roller.

 

生头杆(Head rod)

 

每个锭位有一个生头杆,生头时,拉下生头杆,将丝条绕过生头杆顶部导丝器,复位后丝条自动导入热箱加热板沟槽中。

Each spindle has a so-called head rod. When the head is produced, the head rod is pulled down, and the yarn is wound around the top guide of the head rod. After the reset, the thread is automatically introduced into the groove of the hot box heating plate.

 

止捻器(Stopper)

 

止捻器安装在生头杆顶部,它的作用就是阻止丝条捻度从热箱向外传递,同时减少加捻张力,从而保证DTY的弹性和强度性能。

The snoring device is installed on the top of the stalk rod, and its function is to prevent the thread tweeth from being transmitted outward from the hot box, and at the same time reduce the twisting tension, thereby ensuring the flexibility and strength performance of the DTY.

 

第一加热器(First heater)

 

第一加热器一般为带有凹槽的弧形热板,高速行走的丝束在凹槽内通过,为了避免和减少丝对热板表面的磨损和油剂的化学腐蚀,凹槽表面镀铬或喷涂陶瓷,凹槽的表面具备相当的光洁度以免损伤丝条。凹槽的几何形状与丝条高速行走时在槽内的稳定性有关,如槽与丝条接触面较平坦,则丝在高速行走时,容易向两旁滑动,使丝条受热不匀,弹力丝的质量下降,因此槽形一般设计成V型。

The first heater is generally a curved hot plate with a groove, and the high-speed walking tow passes through the groove. In order to avoid and reduce the abrasion of the surface of the hot plate and the chemical corrosion of the oil, the surface of the groove is chrome-plated or Spray ceramic, the surface of the groove has a fairly smooth surface to avoid damage to the thread. The geometry of the groove is related to the stability of the thread in the groove when the wire is running at a high speed. If the contact surface between the groove and the wire is relatively flat, the wire is easy to slide to both sides when the wire is traveling at a high speed, so that the wire is unevenly heated, and the elastic wire is elastic. The quality of the groove is reduced, so the groove shape is generally designed to be V-shaped.

 

在实际生产中,我们必须经常地检查热箱的丝道,并每隔2-3个月要进行一次清洁。因为一热箱温度的高低直接影响丝的卷曲性、膨松性。进而影响染色性能。故生产中丝越偏离热箱丝道,则变形丝条越差,染色等级越低。如果大部分或完全跑出丝道,则成品丝将成僵丝。

In actual production, we must always check the wire path of the hot box and clean it every 2-3 months. Because the temperature of a hot box directly affects the curling and bulkiness of the wire. In turn, it affects the dyeing performance. Therefore, the more the silk in the production is deviated from the hot box thread, the worse the deformed yarn and the lower the dyeing level. If most or all of the wire runs out, the finished wire will become stiff.

 

冷却板(Cooling plate)

 

丝条经过第一热箱后的温度较高,为使丝条具有足够的刚性,使加捻过程正常进行,须将丝条经冷却板冷却至80℃。冷却板的长度一般为1.5M左右。

The temperature of the thread after passing through the first hot box is relatively high. In order to make the yarn have sufficient rigidity to allow the twisting process to proceed normally, the yarn must be cooled to 80 ° C through the cooling plate. The length of the cooling plate is generally about 1.5M.

 

假捻器(False twister)

 

假捻器分为叠盘式和皮圈式两类,叠盘式假捻器由三组同样速度的摩擦盘(主动轮、辅助轮、紧压轮)组成,由高速转动的磨擦表面直接带动丝束得到加捻。皮圈式假捻器则由一对保持稳定接触的皮圈组成,通过皮圈的运动加捻丝条。假捻器的作用是产生机械扭曲应力,以便变形加工。它是德赢入口机的核心。

The false twister is divided into two types: stacking disc and apron. The stacking disc false twister consists of three sets of friction discs (drive wheel, auxiliary wheel, compacting wheel) of the same speed, which are directly driven by the high-speed rotating friction surface. The tow is crowned. The apron false twister consists of a pair of aprons that maintain a stable contact, and the apron is applied by the movement of the apron. The function of the false twister is to generate mechanical torsional stress for deformation processing. It is the core of the texturing machine.

 

第二罗拉(中间罗拉)/Second Roll (middle Roller)

 

中间罗拉很重要,通常它的速度即所谓的车速。要求它的皮圈架握持力要强,防止逃捻丝的发生。

The middle roller is very important, usually its speed is the so-called speed. It is required to have a strong holding of the apron frame to prevent the escape of the silk.

 

第二加热器(Second heater

 

第二热箱常用非接触加热管,借助管壁的热辐射使丝条受热,由于气流、静电和张力的影响,丝条在热管中晃动,因此实际上丝束与管壁有时也有接触,因此又称为半接触式加热形式。通常采用热管直径为3-4CM的内壁光洁度较好的不锈钢管。有联笨加热和电加热两种形式。

The second hot box is usually a non-contact heating tube, and the filament is heated by the heat radiation of the tube wall. The filament is swayed in the heat tube due to the influence of air flow, static electricity and tension, so the tow is sometimes in contact with the tube wall, so Also known as the semi-contact heating form. A stainless steel tube having a good inner wall finish with a heat pipe diameter of 3-4 CM is usually used. There are two forms of heat and electric heating.

 

第二热箱温度提高,成品纤维的卷曲率(弹性)下降。沸水收缩率降低,尺寸稳定性提高,同时丝的残余扭矩变小。

The temperature of the second hot box is increased, and the crimp ratio (elasticity) of the finished fiber is lowered. The boiling water shrinkage rate is lowered, the dimensional stability is improved, and the residual torque of the wire is reduced.

 

第三罗拉(Third roller

 

对辊的握持要求相对要高,但较W2、W1要求低些。其作用是形成OF2(即定型超喂)进行相对松驰状态定型,消除大部分变形中的内应力,使膨松性适中,弹性适中,沸水正常,尺寸稳定性好为宜。

The holding requirements for the rolls are relatively high, but lower than the requirements of W2 and W1. Its role is to form OF2 (ie, stereotyped super-feeding) to relatively loose state setting, eliminate most of the internal stress in deformation, make the bulkiness moderate, moderate elasticity, normal boiling water, good dimensional stability.

 

油轮(Tanker

 

油轮的作用主要是给低弹丝加上适当的油剂,其作用是提高纤维的集束性,增加纤维的平滑性,改善纤维的抗静电性,适应后道织造的要求。

The role of the oil tanker is mainly to add a suitable oil agent to the low-elastic yarn. The function of the oil tanker is to improve the bundleability of the fiber, increase the smoothness of the fiber, improve the antistatic property of the fiber, and adapt to the requirements of the subsequent weaving.

 

检丝器、剪丝器(Detector, wire cutter

 

德赢入口机中的检丝器又叫断丝探测器或敏感器,是与剪丝器(又叫切丝器)自动配合动作的,当丝条在运行中发生断丝时,由检丝器感知,然后以电信号触发剪丝器动作,将断丝锭位的丝条在喂入罗拉前切断,以防丝条缠绕在罗拉上。

The yarn detector in the texturing machine is also called a broken wire detector or a sensor, and is automatically matched with a wire cutter (also called a wire cutter). When the wire is broken during operation, the wire detector is used. Perceive, then trigger the wire cutter action with an electric signal, and cut the wire of the broken wire position before feeding the roller to prevent the wire from being wound around the roller.

 

吸丝器(Suction device

 

德赢入口机的吸丝器的作用是帮助升头,落筒及剥丝。

The function of the wire feeder of the texturing machine is to help raise the head, drop the drum and peel the wire.

 

吸烟装置(Smoking device

 

纤维在加热定型时挥发出来的油剂,污染空气、恶化操作环境、影响工人身体健康,故在第一热箱出、入口处装有吸烟口,将挥发的油烟及热量通过排风机排出室外,部分油烟冷凝液流入风机下的油剂收集桶内的丝卷纸管长度 只有142.5 mm,生产的丝卷定重受到一定限制,同时由于丝卷成形与常规产品也存在差别 ,所以会对客户的使用带来一些不便。

The oil that volatilizes when the fiber is heated and shaped, pollutes the air, deteriorates the operating environment, and affects the health of the workers. Therefore, a smoking port is installed at the exit and entrance of the first hot box, and the volatile fumes and heat are discharged to the outside through the exhaust fan. Part of the soot condensate flows into the oil collection tank under the fan. The length of the coiled paper tube is only 142.5 mm. The weight of the produced coil is limited. At the same time, due to the difference between the roll forming and the conventional product, it will be for the customer. Use brings some inconvenience.
