Ceiling type reciprocating short yarn dropping device

Abstract

The invention discloses a ceiling type reciprocating short yarn dropping device. The ceiling type reciprocating short yarn dropping device comprises a frame, a first longitudinal rotating shaft and a first motor, wherein the frame is hung above a yarn barrel; the first motor is in transmission connection with the first longitudinal rotating shaft; a front transverse chain and a rear transverse chain which are in transmission connection with the frame are respectively arranged at two ends of the first longitudinal rotating shaft and on the frame; a front transverse sliding barrel and a rear transverse sliding barrel are respectively arranged on the bottoms of the front transverse chain and the rear transverse chain fixedly; a second longitudinal rotating shaft is rotatably arranged between the front sliding barrel and the rear sliding barrel; a second motor which is in transmission connection with the second longitudinal rotating shaft is arranged on one side of the second longitudinal rotating shaft; a longitudinal chain is arranged between a front second driven gear and a rear second driven gear; a longitudinal sliding barrel is fixedly arranged on the bottom of the longitudinal chain; and a yarn guiding barrel which is hung above the yarn barrel is arranged on the outer wall of one side of the longitudinal sliding barrel, and is in sliding fit with the longitudinal sliding barrel. The ceiling type reciprocating short yarn dropping device is reasonable and reliable in structure; movement of the barrel is replaced by movement of yarns; the mechanical structure is simplified; and the load is greatly reduced.

Description

technical field [0001] The invention relates to a short wire suspended ceiling type reciprocating wire doffing device. Background technique [0002] At present, the reciprocating device of the short yarn falling barrel adopts the method that the tow is vertically fixed and falls, and the silk barrel moves on the reciprocating chain plate. This method requires a heavy reciprocating chain device, and both large and small car motors require frequency converters to switch forward and reverse frequently. [0003] In daily use, the trolley motor drives the reciprocating movement of several tons or even dozens of tons of silk barrels, which consumes a lot of energy; at the same time, the cart motor drives the entire chain plate device and silk barrel to move, and the load is greater than that of the trolley. . Both consume large amounts of energy; [0004] The motors of large and small cars are reciprocated by the frequency converter through forward and reverse rotation, bec...

AI Technical Summary

Problems solved by technology

[0003] In daily use, the trolley motor drives the reciprocating movement of several tons or even dozens of tons of silk barrels, which consumes a lot of energy; at the same time, the cart motor drives the entire chain plate device and silk barrel to move, and the load is greater than that of the trolley.

Both consume large amounts of energy;

[0004] The motors of large and small vehicles are reciprocated by the frequency converter through forward and reverse rotation, because the loads of both are large, and the commutation requires braking resistors to consume regenerative power, and frequent switching will greatly damage the life of the frequency converter;

[0005] In addition, the current reciprocating devices are all running under the pit. Once the chains and other failures, forklifts are difficult to access, often causing the barrel full of yarn to fall to the ground or even forcing the spinning to stop.
