It should be strong andstable, made with high quality steel, well balanced for anti-vibration.扣剪线机构（04E）安装在前大梁上，刺布引线机构 06E 安装在横梁上。

04E，06E 的安装要遵守共面及垂直. . . . .的原则The thread hooking and trimming system (04E) is installed on the front lower beam and the stitchingsystem (Arm or Head) is installed on the front upper beam. The installation of 04E and 06E should be onthe exact same flat surface, in order to make sure the aligned stitching and trimming.调节地脚螺丝使机架平稳，从而减少震动，也可降低断线率Adjust the supporting bolts to achieve good leveling of the whole machine, in order to reduce vibration and thread breakage.2．．．．主轴变速箱主轴变速箱主轴变速箱主轴变速箱（（（（02E））））The Main Shaft Gear Box （（（（02E））））02E 上的刻度盘表示相位角。

The dial angle of 02E shows the position of the system connected to the main shafts.通过主轴电机旋转，带动主轴皮带轮，通过皮带转动，传给上下轴运动从动皮带轮降速（小皮带轮带动大皮带轮） ，再通过带轮，皮带带动上下轴一起动作，实现主机构的运动（主机构——04E，06E，07E 等） 左右箱体，设在左右两头起枕头作用The main shaft motor rotates to drive the arm, rotary hook and trimming system. The transition bythe pulley and belts fulfill the functioning of the stitching and trimming system. (The major mechanicalsystem are 04E，06E，07E, etc.)3．．．．光电编码器光电编码器光电编码器光电编码器 Rotary Encoder监测主轴旋转位置，记忆 04 轴的转数Detect the rotating position of main shaft and carry out the data communication between the mainshaft and electronic control system.平绣电脑绣花机的机械机构 Flat Embroidery Machine Mechanical Structure2主轴旋转后带动编码器得出电脉冲表明旋转相位（角度） ，反馈给电脑，电脑将信号传给电器（执行部件）以完成各部分预定设置动作，原为一个部件，现为外购件。

The rotation of the main shaft is recorded by the rotary encoder, then the data is sent to the maincontrol system. Then the main control system sends back command to the encoder, the main motor andthe X/Y axis motor, according to the punching data.4．．．．扣线剪线机构扣线剪线机构扣线剪线机构扣线剪线机构（（（（04E））））Hook and Trimming System (04E)完成旋梭旋转和剪线两个作用This system performs the rotation of rotary hook, picking of thread and trimming.① 通过固定在下端的伞齿轮，将运动方向旋转 90°The main lower shaft rotates and drives the rotary hook via the bevel gears fixed onthe lower shaft and rotary hook shaft.带动旋梭以两倍于主轴的旋转速度旋转， 通过梭尖旋转带动上线在梭壳上滑过与下线形成一个线套，完成刺绣 1 针的动作。

The rotary hook rotates at double speed of the main lower shaft, and the hook picksthe upper thread to rotate along the bobbin case, then the upper thread and the bobbinthread winds together and form a knot,achieving one stitch.② 完成剪线动作，由 04E 的旋转电磁铁工作带动上线保持器 04-15E，把线扣到梭芯上，由剪线杆带动剪线刀 04-29E 工作，将上下线剪断扣线→剪线→勾线The performance of trimming. The trimming solenoid cam system drives the trimming rod,then the wide picker 04-15E picks the thread onto the bobbin case, then the knives 04-29Eare driven by the trimming rod to cut the upper and bobbin threads.5 5 5 5．．．．换色机构换色机构换色机构换色机构（（（（05E05E05E05E））））C C C Colorolorolorolor C C C Changhanghanghange e e e S S S Systemystemystemystem（（（（05E05E05E05E））））动力源是通过可逆转. . .的换色电机转动，带动换色凸轮（换色凸轮是根据针位的多少设计相同针位点。

针位越多，换色凸轮越长，每个针位距离为 15mm） ，旋转变成换色轴的平行移动其换色轴通过机械连接传给 07E（挑线机构）的针杆箱，推动针杆箱由 1→6，6→1 针位移动，从而达到换色的目的Color change motor drives the color change cam, then the color change cam convert therotation motion to parallel movement of the color change rod. Then the color change rod平绣电脑绣花机的机械机构 Flat Embroidery Machine Mechanical Structure3pulls or pushes the needle bar case on the arm/ head to change the needle / color. Themoving distance between each two needles is 15MM.The movement of the color change motoris recorded by the needle position card, then sends the needle position signal to maincontrol system.剪线轴及换色轴都是Φ6 的不锈钢轴。

The trimming rod and color change rod are stainless steel rod in diameter Φ6.6．．．．刺布引线机构刺布引线机构刺布引线机构刺布引线机构（（（（06E)Arm / Head (06E Stitching System)挑线杆及驱动块极限行程为 44mmThe traveling distance of the take-up level and the needle bar reciprocator is 44mm.① 通过上轴（06 轴）旋转带动锁在上轴的曲柄连杆机构（四连杆机构） ，带动驱动滑块沿着竖轴上下运动，由驱动块带动 07E 的针杆做上下运动实现刺布引线功能The needle bar is driven by the reciprocator, which is connected to lever, connected to the Cam Setinside the Arm. The Cam Set is driven by the main upper shaft, which is driven by the main motor. Thenvertical movement of the needle bar/ needle performs the feeding of upper thread and stitching.② 带动挑线杆做半回转运动：上轴旋转运动时带动固定于曲轴上的凸轮做回转运动，从而通过其中的凸轮滚子运动带动扇形齿轮做半回转运动，达到送线挑线的目的。

06 轴（Φ15）是由偏心套连接（用平衡块平衡 06E 所产生的离心力） ；04 轴（Φ15）是由同心套连接绣花机的心脏部分：06E＞07E＞04EThe take up gear and lever is driven by the Cam Set to feed the upper thread.The key system of embroidery machine are : 06E＞07E＞04E7．．．．挑线机构挑线机构挑线机构挑线机构（（（（07E））））Needle Bar Case (07E)① 换色：根据颜色的多少针杆有多少，每个针杆下面的针的线道穿有不同颜色的线，与换色机构配合完成推动针杆移动到相应的位置，从而达到换色的目的Performs the color change: the needle bar case is driven to move from 。
