一種線筒放線裝置
本專利技術(shù)涉及化纖機(jī)械設(shè)備領(lǐng)域,特別涉及一種線筒放線裝置。
技術(shù)介紹
在化纖機(jī)械設(shè)備的作業(yè)工藝中,常常需要對卷滿紗線的線筒進(jìn)行放線工藝,其后再對紗線進(jìn)行其它的加工工藝;而在對線筒放線的過程中,由于紗線是成螺旋的繞于卷筒之上,所以紗線與線筒分離的位置一直在改變,進(jìn)而導(dǎo)致線筒在放線過程中紗線的張緊松弛度在改變,使的紗線放線時,紗線時而繃緊、時而松弛。
技術(shù)實(shí)現(xiàn)思路
本專利技術(shù)要解決的技術(shù)問題是提供一種放線平穩(wěn)、紗線輸送張力穩(wěn)定的線筒放線裝置。為了解決上述技術(shù)問題,本專利技術(shù)的技術(shù)方案為:一種線筒放線裝置,包括架體、從動輥、擺臂、轉(zhuǎn)軸;所述架體包括左、右相對平行設(shè)置的連接臂,連接臂前端連接從動輥的兩端;連接臂后端連接架體的殼體,殼體設(shè)有中空的內(nèi)腔;所述轉(zhuǎn)軸水平設(shè)置于所述內(nèi)腔之內(nèi);所述轉(zhuǎn)軸表面設(shè)有螺旋線形的滑槽,所述滑槽為兩條,其螺旋方向分別為正旋、反旋,兩滑槽的兩側(cè)末端相互對接,并平滑過渡;所述擺臂尾端設(shè)有滑塊,所述滑塊設(shè)置于滑槽之內(nèi),滑塊大小形狀與滑槽連接相適配;所述擺臂前端設(shè)有擺頭,擺頭搭設(shè)于從動輥之上,其工作時在從動輥上水平左右擺動;擺頭前部設(shè)有U形導(dǎo)線槽,導(dǎo)線槽貫穿擺頭上、下表面;優(yōu)選的,所述轉(zhuǎn)軸與電機(jī)輸出軸連接。優(yōu)選的,為了保證放線的張緊力度一致,使紗線輸送穩(wěn)定,所述連接臂上還設(shè)有導(dǎo)線弧柱;導(dǎo)線弧柱為月牙形弧柱設(shè)于從動輥的斜上方。相對于現(xiàn)有技術(shù),本專利技術(shù)的有益效果為:本專利技術(shù)的轉(zhuǎn)軸和擺臂的結(jié)構(gòu)與連接關(guān)系設(shè)計(jì),使得擺臂能實(shí)現(xiàn)放線時對紗線的平穩(wěn)牽引;弧形柱的設(shè)計(jì)使放線過程中,紗線張緊力度一致,使得紗線輸送緊繃穩(wěn)定。附圖說明圖1為本專利技術(shù) ...
