Technical Field

[0001] The utility model relates to the field of textile equipment, and more specifically, to a turning mechanism for a short car track, a series-connected short car track, and a spinning frame. Background Art

[0002] A spinning frame is an important piece of equipment with a large area and a large quantity in the production process of the textile industry. The quality of its performance directly affects various aspects such as the quality of the spun yarn and economic benefits. At present, a collective doffing device is generally provided on a spinning frame. The collective doffing device is a device on the spinning frame that automatically removes the full yarn tubes and simultaneously automatically replaces them with empty tubes. During operation, the yarn tubes are generally transported by means of yarn tube seats installed on a steel belt. The track transports the empty bobbin tubes to the standby position during operation and transports the full bobbin tubes to the tube yarn transfer box or the winding machine, thereby achieving the purpose of mutually exchanging and recycling the full bobbin tubes and the empty bobbin tubes.

[0003] A spinning frame belongs to large-scale textile equipment, which is expensive and occupies a large area, and has certain requirements for the workshop. If limited by the workshop area, the spinning frame cannot be fully expanded, and the steel belt of the yarn tube seat needs to make an appropriate turn. If a customized design is made for the track, it takes a long time and the cost is high.

[0004] In view of the above problems, it is necessary to provide a turning mechanism for a short car track, a series-connected short car track, and a spinning frame, which can meet the requirements of the steel belt of the yarn tube seat for turning on the track at low cost and improve the reasonable area planning of the spinning frame.

[0046] See Figure 4 , a series-connected short car track, comprising eight turning mechanisms 1, two tracks 2, two track connectors 3 and a bobbin tray connecting belt 4. The two tracks 2 are arranged between the two track connectors 3. The eight turning mechanisms 1 are respectively fixedly installed at both ends of the two tracks 2 and the two track connectors 3. The bobbin tray connecting belt 4 is installed on the track 2 and passes through the gaps between the two guide wheels 11 of the turning mechanism 1 to serially connect the two tracks 2 and the two track connectors 3 in sequence.

[0047] In this embodiment, the series-connected short car track is formed by the turning mechanism, which can facilitate the layout of the track within the track connector, is not limited by the length of the track connector, is convenient for the transformation of the spinning frame track, can make better use of the site, and can also avoid the limitation of the site terrain resulting in the inability to install the spinning frame.
