Guide bar movement mechanism for full-width weft insertion machine

Abstract

The invention discloses a guide bar movement mechanism for a full-width weft insertion machine. The guide bar movement mechanism comprises a machine body, an upper cross beam and a swing driving device which is arranged between a connecting rod frame and a guide bar swing arm and used for driving the guide bar swing arm to swing; the connecting rod frame is arranged on the machine body; a swing shaft is installed on the upper cross beam, and a guide bar swing arm rotationally sleeves the swing shaft; a guide bar cradle is arranged on the guide bar swing arm; the swing driving device comprisesa main shaft, an eccentric wheel and an eccentric sleeve, the main shaft is rotationally supported on the connecting rod frame, and the eccentric wheel sleeves the main shaft, so that the eccentric wheel is driven to rotate through the main shaft; the eccentric sleeve is matched with the outer circumferential direction of the eccentric wheel, so that the eccentric sleeve is driven to swing in a reciprocating mode through the rotation of the eccentric wheel; the eccentric sleeve is connected with the guide bar swing arm through a transmission piece, so that the eccentric sleeve drives the guidebar swing arm to swing through the transmission piece. The guide bar cradle can work rapidly and stably for a long time.

Description

technical field [0001] The invention relates to a bar movement mechanism for a full-width weft insertion machine, which belongs to the field of textile machinery for a full-width weft insertion machine. Background technique [0002] The existing bar movement mechanism for full-width weft inserting machines is complex and heavy, and most of them use two types of motion: conjugate cam and crankshaft. The previous conjugate cam needs to process a curved extension on the cam to complete a reciprocating action. Dead spots may appear during processing, and the running speed cannot be increased, and it is difficult to move stably for a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a bar movement mechanism for a full-width weft insertion machine, which can make the bar cradle work quickly and stably for a long time. [0004] In order to solve the above-mentioned tec...

[0002] The existing bar kinematic mechanism for full-width weft inserting machines has a complex and heavy structure, and most of them use conjugate cams and crankshafts. The previous conjugate cams need to process curved extensions on the cams to complete a reciprocating action. In the process of processing, there may be dead spots, the running speed cannot be increased, and it is difficult to move stably for a long time
