Airbag gland-type tube snapping device for integral doffer of ring spinning frame

Abstract

The invention relates to an airbag gland-type tube snapping device for an integral doffer of a ring spinning frame. The airbag gland-type tube snapping device comprises a pneumatic rack, lug connection seats, a tube snapping device seat, a gland, a seal ring, a positioning post, an airbag, a bobbin, a spindle, and a V-shaped positioning post. The tube grapping device seat is connected with the pneumatic rack through the lug connection seats; the pneumatic rack is provided with a positioning hole and a V-shaped groove corresponding to the positioning post and the V-shaped positioning post on the tube snapping device seat; the tube snapping device seat is provided with an air hole which is communicated with an air inlet of the pneumatic rack; the seal ring is arranged on the tube snapping device seat and is positioned at the connection of the air inlet and the air hole; the airbag is arranged on the tube snapping device seat; when inflated, the airbag expands and clamps the bobbin; the bobbin is arranged on the spindle, and the bobbin can be pressed down onto the spindle until the bobbin reaches the gland in the specified position onto the tube snapping device seat. The airbag gland-type tube snapping device has a secondary overload auto-protecting function, is safer and more reliable to use and is convenient to maintain.

Description

technical field [0001] The invention belongs to a part of a textile machine, and in particular relates to a collective doffing airbag gland-type pipe gripper of a ring spinning frame. Background technique [0002] At present, the collective doffing of ring spinning frames is widely used in textile enterprises, which greatly reduces the number of workers and improves the operating efficiency. The airbag-type tube grabber of the prior art can only maintain the clamping state during the whole process of clamping the bobbin to the spindle until the bobbin is pressed into the bottom of the spindle. In this "spindle pressing" process, the air bag gripper must hold the bobbin all the way, which increases the wear of the air bag and affects the service life of the air bag. Once the air bag is damaged, it can only be replaced with a new air bag gripper, and Once the airbag-type tube grabber in the prior art encounters unexpected resistance when clamping the bobbin (for example, the ...

Problems solved by technology

In this "spindle pressing" process, the air bag gripper must hold the bobbin all the way, which increases the wear of the air bag and affects the service life of the air bag. Once the air bag is damaged, it can only be replaced with a new air bag gripper, and Once the airbag-type tube grabber in the prior art encounters unexpected resistance when clamping the bobbin (for example, the bobbin is skewed, the yarn is wrapped on the spindle, etc.), the structural design requires that the airbag-type tube grabber should automatically break away from the bracket, but the airbag-type tube grabber should automatically break away from the bracket. After the pipe grabber is automatically disengaged, the air holes on the air frame are exposed, resulting in air leakage, which causes the air pressure of adjacent spindles to drop and cause more spindles to fail
