Carding cavity pressure regulation mechanism for air suction type rotor spinning machine

Abstract

The utility model relates to the technical field of spinning machines, in particular to a carding cavity pressure regulation mechanism for an air suction type rotor spinning machine. The carding cavity pressure regulation mechanism comprises a cavity, an impurity discharging port and a cotton feeding port, wherein the impurity discharging port and the cotton feeding port are distributed in the inner wall of the cavity symmetrically about the axis of the cavity, a connection threaded hole is formed in the lateral end face of the cavity and positioned between the impurity discharging port and the cotton feeding port, a through hole is formed in the position on the inner wall of the cavity, corresponding to the connection threaded hole and penetrates through the cavity to be communicated with the connection threaded hole, a connection rod is fixedly connected into the connection threaded hole, and a dust cover is arranged on the connection rod. The connection threaded hole is communicated with the through hole, so that air pressure at the position of the through hole in the cavity is communicated with air pressure outside the cavity, and the effect of regulating air pressure at the position of the through hole is achieved. The connection rod is fixedly connected into the connection threaded hole, and the dust cover is arranged on the connection rod, so that other impurities cannot flow into the cavity from the outside of the cavity in the pressure regulation process.
本实用新型涉及纺纱机技术领域,特别是涉及一种抽气式转杯纺纱机的分梳腔体调压机构,其包括腔体、排杂口和进棉口,排杂口和进棉口以腔体的轴心线为对称分布在腔体的内壁,所述在腔体的侧端面上并位于排杂口及进棉口之间设有转接螺纹孔,且在腔体的内壁与转接螺纹孔对应的位置设有通孔,该通孔贯穿腔体与转接螺纹孔相连通,转接螺纹孔上固连一转接杆,转接杆上设有一阻尘罩。本实用新型所设转接螺纹孔与通孔相连通,使得腔体内通孔部位的气压与腔体外的气压相连通,具有调节通孔部位的气压的作用;转接螺纹孔上固连一转接杆,转接杆上设有一阻尘罩,该结构设置有效地保证调压过程中不会使其他杂质从腔体外流到腔体内。
