Rotary type reciprocating short yarn dropping device

Abstract

The invention discloses a rotary type reciprocating short yarn dropping device. The rotary type reciprocating short yarn dropping device comprises a yarn guiding tube, wherein the yarn guiding tube is hung above a yarn barrel; an outer tube is rotatably arranged on the outer wall of the yarn guiding tube; a driven gear is fixedly arranged on the outer wall of the outer tube; a motor which is in transmission connection with the driven gear is arranged on one side of the outer tube; a positioning block is fixedly arranged on the driven gear; a proximity switch is fixedly arranged on the outer wall of the yarn guiding tube, and is electrically connected with the motor through a PLC (programmable logic controller) and a frequency converter sequentially; a rotating shaft is rotatably arranged on the bottom of the outer wall on one side of the outer tube; a draw bar and a baffle are respectively connected with the upper side and the lower side of the rotating shaft fixedly; an end of the draw bar is fixedly connected with spherical ejectors; annular guiding mechanisms are respectively fixed at the upper end of the outer wall of the yarn guiding tube; and the spherical ejectors are abutted to the bottoms of the annular guiding mechanisms. The rotary type reciprocating short yarn dropping device is reasonable and reliable in structure; and the outer tube rotates around the yarn guiding tube, the baffle regularly swings vertically, and the frequency converter moves timely, so that yarn strands drop in the yarn barrel in a similarly chrysanthemum-shaped manner.

Description

technical field [0001] The invention relates to a short filament rotary reciprocating 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 vehicles are reciprocated by the frequency converter through forward and reverse rotation, because the load...

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;

[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.
