Description
Technical Field
The invention relates to the field of textile machinery, in particular to a back roller lock cover and a spun yarn broken end and roving stopping device.
Background
The spinning frame needs to stop feeding the roving when the broken ends occur. A roving automatic stop device is additionally arranged in a drafting zone of a spinning machine, an inserting piece, namely a lock cover, is inserted between a back roller and a jaw of a back leather roller, so that yarns are separated from the contact of the back roller, the yarns are clamped between the lock cover and the back leather roller to block the feeding of the rovings, and the rovings are stopped from being conveyed forwards.
Since the lock cover is inserted between the rear roller and the rear leather roller, and the roving automatic stop device needs to be manually reset when an operator performs spun yarn splicing, in the prior art, a reset rod on a sliding plate of the roving automatic stop device is pushed, and then the lock cover is driven to withdraw from a jaw of the rear roller and the rear leather roller, so that the spun yarn splicing is performed after the roving is fed again. However, the existing reset rod is arranged on the sliding plate, or the rear end of the sliding plate is positioned at the rear part of the roving automatic stop device; or the middle section of the sliding plate, the front part of the roving automatic stop device and the rear part of the yarn guide loudspeaker. Because the position that the release link is located is back, if the release link is at roving stop motion rear portion, the operative employee is inconvenient to observe. The operation is inconvenient because of the obstruction of the front drafting device of the spinning machine; if the reset rod is arranged at the front part of the roving automatic stop device and at the rear part of the yarn guide horn, the possibility of interference of the yarn guide horn exists; moreover, the pneumatic cradle support rod of some pneumatic cradle drafting type spinning machines has an air pipe at the position where roving is mounted for automatic stop, so that the observation and operation of the original reset rod are not facilitated.
The invention is an improvement for solving the problems, and is suitable for a plane drafting spinning machine and a plane pneumatic drafting spinning machine; the method is also suitable for a V-shaped drafting spinning machine and a V-shaped pneumatic drafting spinning machine; the roving automatic-stopping cover is more suitable for occasions where roving automatic-stopping covers are not convenient to reset.
