Automatic lifting mechanism of bobbin creel

Abstract

The invention discloses an automatic lifting mechanism of a bobbin creel. The automatic lifting mechanism comprises a slewing mechanism and a double acting cylinder, a support is fixed to a textile machine frame, a positioning shaft is arranged at the upper end of the support, a cylinder installation shaft is arranged at the lower end of the support, a slewing seat is hinged to a positioning shaft, the end of a piston rod of the double acting cylinder is hinged to the upper corner of the sector edge of a slewing plate, a base is hinged to a cylinder installation shaft, the end of a piston rod of a lifting cylinder is hinged to the lower corner of the sector edge of the slewing plate, and a cylinder seat of the lifting cylinder is hinged to the cylinder installation shaft. The automatic lifting mechanism is compact in structure and fast in response; the lifting cylinder replaces a complex clutch component, an air supply system is controlled to be turned on and off via electric signals, and the automatic lifting mechanism is convenient and quick to operate and high in automation degree; when the size of yarn reels changes, the bobbin creel lifts, response time of resetting is adjusted by only adjusting air supply pressure, and simplicity and convenience are achieved.

Description

technical field [0001] The invention belongs to the field of spinning machinery, and in particular relates to a mechanism for automatically lifting creels during bobbin forming. Background technique [0002] The creel lifting mechanism is the key component to realize the disengagement and contact between the yarn bobbin on the creel and the winding roller. During the bobbin winding and forming process, if the yarn is broken, the creel lifting mechanism needs to make the bobbin detach from the winding roller and stop at a certain position for yarn splicing. After the yarn splicing is completed, the bobbin must be quickly and Winding roller contact. [0003] Chinese Patent No. 201310506677.8 discloses a creel, including a clamping assembly, a clutch assembly, a double-acting cylinder and a positioning shaft of the creel. The clamping assembly includes a revolving seat. The revolving seat is in the shape of a cylinder. There is a fan-shaped flat plate vertically in the middle...

AI Technical Summary

Problems solved by technology

[0004] The defects of the creel lifting mechanism with the above structure are: the structure is scattered and complicated, there are many adjustment links, and multiple actions are required to complete a task; the separation of the ratchet teeth from the ratchet and the attraction of the electromagnetic clutch and the clutch plate must require external force The spinning machine needs to increase the corresponding mechanism; when the bobbin is detached from the winding roller, the lever, ratchet teeth and clutch plate are greatly impacted by the tension spring, which is prone to failure
