The utility model relates to a textile equipment product, in particular to a turnover presser foot used for sewing with long and narrow lines. For the narrow line sewing flip pressure foot, including pressure tripod, external pressure and external pressure foot pedal driving mechanism, internal pressure and internal pressure foot driving mechanism is arranged on the foot, foot pressure foot and a holding groove of the presser foot frame the external pressure, the pressure in the foot is arranged on the baseboard groove. And the pressure foot frame between the pressure foot driving mechanism connected with a pressure foot to drive the internal pressure foot pressure groove or inward foot presser foot frame to rotate. For the narrow line sewing flip foot long feet can be used for internal pressure cuffs, front lines sewing, when the internal pressure plate to the presser foot frame to rotate when the cloth is pressed to the sewing machine needle around the inner pressure gap between the foot and foot frame suture, when the internal pressure foot plate press foot groove rotates the cloth for release, the narrow lines sewing flip foot has the advantages of simple structure, convenient use.

用于狭长线条缝纫的翻转压脚
本技术涉及纺织设备产品,具体是一种用于狭长线条缝纫的翻转压脚。
技术介绍
现有的缝纫机都设有压脚,在缝纫时用于压住布料,这种常用的压脚,只能简单地将两块布料压在一起,然后将待缝纫的位置送到缝纫机针工作处。在缝纫工艺中,经常需要将一块面料缝在另一块上,如将一块商标缝纫在布料上,在缝纫时需要形成一圈封闭的缝纫线迹。而现有的缝纫机压脚因为无法方便地压住小块的缝料,也不能自动化地让缝纫机针沿小块缝料周边缝纫一圈构成封闭的线迹。为解决上述问题,授权公告号为CN203096374U的技术专利公开了一种用于缝纫机的翻转压脚,包括设有旋转支轴的压脚架、能绕旋转支轴旋转用以压住物料外边缘的外压脚框和能绕旋转支轴旋转用以压住物料中部的辅助压脚板,其特征是:设有用于支撑辅助压脚板的曲轴和用于带动曲轴旋转的旋转气缸;所述旋转气缸的驱动杆通过万向连接轴与所述的曲轴相连接,带动所述曲轴的曲折部翻转。该种压脚板通过旋转气缸驱动旋转,其结构复杂、生产和维护成本高,此外该种翻转压脚适用于在一侧边缘缝合使用,而不适用于狭长线条如袖口、门襟处的缝纫。
