    工作原理：

    由鋁梁、鋁梁固定盤、鋼帶循環(huán)導(dǎo)出頭、鋼帶循環(huán)頭、閉環(huán)鋼帶組成的模具安裝在纏繞機主傳動裝置。當(dāng)纏繞機主傳動裝置帶動模具旋轉(zhuǎn)時，鋼帶會纏繞在沿鋁梁固定盤一周均勻分布的鋁梁上，同時在鋼帶推進裝置作用下，鋼帶沿纏繞主軸軸向移動，主軸每旋轉(zhuǎn)一周鋼帶推進裝置將鋼帶沿軸向推進一個鋼帶寬度。當(dāng)鋼帶沿軸向方向推進到鋁梁尾部時，鋼帶進入鋼帶循環(huán)導(dǎo)出頭、鋼帶循環(huán)頭，鋼帶被導(dǎo)入纏繞機主傳動裝置的主軸（中空軸）內(nèi)，經(jīng)鋼帶纏繞導(dǎo)向裝置返回到纏繞的始點。這樣鋼帶形成纏繞、推進、導(dǎo)出、導(dǎo)入、再纏繞循環(huán)過程。當(dāng)鋼帶形成纏繞循環(huán)運動時，在鋼帶上纏繞一層聚脂薄膜、表面氈。同時上方的內(nèi)襯淋膠裝置，結(jié)構(gòu)層淋膠裝置，往鋼帶上淋適量樹脂。內(nèi)襯層切割紗裝置、結(jié)構(gòu)層切割紗裝置往鋼帶上灑上適量短切纖維。加砂裝置往鋼帶上灑上適量石英砂，纏繞紗架提供環(huán)向纏繞纖維紗。當(dāng)鋼帶上環(huán)向纖維、短切纖維、樹脂、石英砂在滾壓裝置作用下充分混合、浸透。在鋼帶作用下沿主軸軸向前進，進入紅外加熱區(qū)，進行加熱固化同時沿主軸軸向繼續(xù)前進并離開鋼帶模具,液壓升降平臺按序升起，平臺上托輥托起固化好管道。管道具有一定長度后在線切割、修整裝置起動對管道進行切割、修整。從而完成管道制作，內(nèi)襯切割紗量、結(jié)構(gòu)層切割紗量、纏繞紗量、石英砂量、樹脂量是預(yù)先設(shè)定好的并由PLC控制。樹脂溫度、石英砂溫度也由PLC控制。

Introduction to CFW Continuous Pipe Filament Winding Machine

Equipment function, composition and working principle:

Function--

As the main equipment in the production line, this CFW 3000 continuous filament winding machine is designed for the GRP pipe manufacturing.

Composition--

It mainly consists of mandrel driving device, overall frame, steel band pusher, beam cam disc, band circulating head, band exit head, beam for band supporting, steel band, liner chopper devices for liner and structure, sand feeding device, chopped roving shelf for liner and structure,  hoop roving shelf for liner and structure, resin mixing and spraying devices for liner and structure , infrared heating system, mylar winder, surface veil winder, external layer winder, pneumatic rollers for liner and structure, finishing pneumatic roller, Hydraulic lifting table, online cutting & grinding device, dust collector, PLC control system, electrical control system, etc.

Working Principle--

The main transmission of the winding machine is assembled with mould consisting of cam disc, band exit head, band circulating head, beams for band supporting and closed-loop steel band.

Once the mould rotates with the transmission, steel band winds on the beams distributed around the circle of cam disc and moves in the axial way under the impetus of pushers. Band will be pushed forward at one band width with every complete revolution of the mandrel. When it arrives the rear end of the beam, steel band will be led into mandrel’s hallow tube via exit head and circulating head, and then return to the very starting point. In this way, steel band forms a circulation process of winding, pushing forward, leading out, leading in and rewinding.    

Wind the mylar and surface veil onto the band as it forms the winding cyclic movement. And, simultaneously, onto the band, spray resin through spraying device for liner layer and structure upward side, spread chopped roving via chopper devices for liner layer and structural layer, feed sand by sand feeding device, and wind hoop roving from the roving shelf. After the hoop roving, chopper, resin and sand on the band are completely mixed and impregnated with the effect of pneumatic roller, it moves forward with band in the axial way into the infrared heating area to be cured and then moves on until leave the band mould. Hydraulic lift table will rise sequentially and the rollers on the table support the cured pipe. Pipe will be cut after it reaches a certain length and both ends are trimmed by online cutting and trimming devices. In this way, the production of a pipe is done. The amount of chopped roving for liner layer and structural layer, hoop roving, sand as well as resin are preset and controlled by PLC which also controls the temperature of resin and sand.
