一种平缝机的头轮装置
本技术涉绗缝机械
,具体是一种平缝机的头轮装置。
技术介绍
平缝缝纫机主要是用一根缝纫线,在缝料上形成一种线迹,使一层或多层缝料交织或缝合起来的机器,平缝机在缝纫设备是最基本的车种,缝制出的线迹整齐美观、线迹均匀,平整牢固,缝纫速度快、操作简便,使用简单易懂。现有的平缝机使用单个偏心轮作为针头上下运动的动力,但在缝料较厚或者较硬时,很难有足够的动力穿过缝料,达到缝纫的效果。
技术实现思路
本技术的目的在于提供一种平缝机的头轮装置,以解决现有技术中使用单个偏心轮作为针头上下运动的动力,但在缝料较厚或者较硬时,很难有足够的动力穿过缝料,达到缝纫的效果等问题。为实现上述目的,本技术提供如下技术方案:一种平缝机的头轮装置,包括机壳和下轮,所述机壳内安装有固定架,所述固定架上安装有固定块,所述机壳底部安装有气缸座,所述气缸座上安装有气缸,所述气缸上连接有气缸主轴,所述气缸主轴上连接有传动块,所述传动块内安装有轴承,所述轴承上安装有转动块,所述转动块上连接有传动轴,所述传动轴上连接有连杆轴,所述连杆轴的一端连接有副轴,所述副轴延伸至机壳的外部,所述副轴上安装有手轮,所述连杆轴的另一端连接有主轴,所述主轴上安装有固定块,所述下轮上设有连接孔,所述下轮上安装有连接轴,所述连接轴共设有两个,所述连接轴关于连接孔对称,所述下轮通过连接轴与上轮相连,所述连接孔内安装有大铜环,所述大铜环内安装有小铜环,所述小铜环安装在主轴的一端。优选的,所述传动轴通过轴承与连杆轴相连。优选的,所述固定块通过轴承与主轴相连。优选的,所述上轮与下轮的底端均设有曲柄安装孔。优选的, ...
