Automatic keyway alignment device for warp beam snapping of warp knitting warping machine

Abstract

The invention relates to a device for automatically aligning the warp beam of a warp knitting warping machine with a key slot. When the lower part of the locking swing arm swings right around the pin shaft under the action of a reset spring on a reset push rod, the boss below the locking swing arm leaves the lower part of the positioning key. When the warp beam moves in a snap-together direction toward the driving head, the driving head enters the warp beam hole, and the positioning key is squeezed and moves downward to overcome the elastic force of the spring. At this time, the warp beam or the driving head is rotated. When the key slot of the warp beam hole is aligned with the positioning key of the positioning key seat, the positioning key automatically moves upward under the elastic force of the spring and enters the key slot of the warp beam hole. When the warp beam continues to move in a snap-together direction toward the driving head and touches the locking push rod, the locking push rod compresses the locking spring and pushes the locking swing arm to swing left around the pin shaft, so that the boss below the locking swing arm is inserted under the positioning key, locking the positioning key, and the positioning key on the driving head cooperates with the key slot of the warp beam hole to drive the warp beam to rotate. The structure is safe and compact, and the problem of automatic key slot alignment of the warp beam of the warp knitting warping machine is solved.

Description

Technical Field

[0001] This patent relates to the field of textile machinery. Background Art

[0002] Warp knitting warping machine is an important process equipment for warp knitting. The warp beam of the warping machine is mainly used to wind the warp yarn for weaving on warp knitting looms. During warping, the warp beam is snapped into the drive head so that the keyway of the warp beam hole matches the locating key of the drive head. The locating key of the drive head drives the warp beam to rotate and wind the yarn. When the warp beam is snapped, the keyway of the warp beam hole and the locating key on the drive head are basically not aligned. It depends entirely on manual observation and touch, which is inconvenient and unsafe to operate. Automatic keyway alignment of the warp beam has become a difficult problem that needs to be solved urgently at home and abroad. Summary of the invention

[0003] This patent provides a device for automatically aligning the keyway of the warp beam of a warp knitting warping machine. During the aligning process, when the warp beam or the drive head rotates, the elastic force of the spring is used to push the positioning key into the keyway of the warp beam hole and lock it, thereby realizing automatic aligning the keyway of the warp beam when the warp beam is aligning.

[0004] The technical solution to achieve the purpose of this patent is as follows:

[0005] A device for automatically aligning the warp shaft of a warp knitting warping machine with a keyway, characterized in that it consists of a positioning key seat, a spring, a spring pin, a positioning key, a locking swing arm, a pin shaft, a locking push rod, a locking spring, a nut, a reset push rod and a reset spring. The positioning key seat is fixed on a driving head of the warp shaft transmission of the warp knitting warping machine, the spring is sleeved on the spring pin fixed to the positioning key seat, the positioning key is installed in a groove below the positioning key seat, the lower hole is sleeved on a spring supported by the spring pin, the locking swing arm is installed in another groove of the positioning key seat, connected by a pin shaft, a locking spring is installed on the locking push rod and passes through the hole above the locking swing arm, and is limited by two nuts, a reset spring and a reset push rod are installed in the hole below the locking swing arm, and the reset push rod is Under the action of the return spring on, the head swings right around the pin axis, so that the boss under the locking swing arm leaves the bottom of the positioning key. When the warp axis moves in the direction of the driving head, the driving head enters the warp axis hole, and the positioning key is squeezed and moves downward to overcome the elastic force of the spring. At this time, the warp axis is rotated or the driving head is rotated. When the keyway of the warp axis hole is aligned with the positioning key of the positioning key seat, the positioning key automatically moves upward under the elastic force of the spring and enters the keyway of the warp axis hole. When the warp axis continues to move in the direction of the driving head and touches the locking push rod, the locking push rod compresses the locking spring and pushes the locking swing arm to swing left around the pin axis, so that the boss under the locking swing arm is inserted under the positioning key, locking the positioning key, and the positioning key on the driving head cooperates with the keyway of the warp axis hole to drive the warp axis to rotate.
