Problems solved by technology

[0002] The traditional eccentric link movement mechanism of the grooved needle used in the full-width weft inserting machine uses a conjugate cam and a crankshaft. The previous conjugate cam needs to process a curved extension on the cam to complete a reciprocating action. It is possible during the processing Bad spots appear, resulting in the inability to increase the speed, and the conjugate cam cannot guarantee a consistent size in the processing, and the accumulated tolerance will become larger and larger, which will affect the speed of the machine

Embodiment Construction

[0019] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, a slotted needle eccentric link movement mechanism for a full-width weft inserting machine, which includes:

[0021] Bed 1, a link frame 11 and a swing shaft seat 12 are fixed on the bed 1, a main shaft 2 is arranged on the link frame 11, and an eccentric wheel 3 is set on the main shaft 2 so as to be driven by the main shaft 2 The eccentric wheel 3 rotates;

[0022] A swing arm 4, one end of the swing arm 4 is hinged on the swing shaft seat 12, and the other end of the swing arm 4 is equipped with a slotted needle 5;

[0023] A pull rod assembly, one end of which is hinged to the middle of the swing arm 4;

[0024] Cooperate with the outer circumference of the eccentric wheel 3, and drive the eccentric sleeve 6...

Abstract

The invention discloses a groove pin eccentric connecting rod movement mechanism for a full-width weft insertion machine. The mechanism comprises a machine body, a swing arm, a pull rod assembly, an eccentric sleeve and a connecting rod; a connecting rod frame and a swing shaft base are fixed to the machine body; a main shaft is arranged on the connecting rod frame, an eccentric wheel sleeves themain shaft, so that the eccentric wheel is driven to rotate through the main shaft; one end of the swing arm is hinged to the swing shaft base, the other end of the swing arm is provided with a groovepin, and one end of the pull rod assembly is hinged to the middle of the swing arm; the eccentric sleeve is matched with the outer circumferential direction of the eccentric wheel so as to drive theeccentric sleeve to swing in a reciprocating mode through rotation of the eccentric wheel; the middle part of the connecting rod is hinged to the connecting rod frame, the eccentric sleeve is hinged to one end of the connecting rod frame, and the other end of the connecting rod is hinged to the other end of the pull rod assembly, so that when the eccentric sleeve swings, the eccentric sleeve drives the swing arm to swing in a reciprocating mode through the connecting rod and the pull rod assembly, and the swing arm drives the groove pin to move in a reciprocating mode. According to the mechanism, the eccentric connecting rod structure is adopted so that the movement speed and movement stability of the groove pin can be greatly improved.

Description

technical field [0001] The invention relates to a slotted needle eccentric link movement mechanism for a full-width weft insertion machine, which is suitable for the field of textile machinery of the full-width weft insertion machine. Background technique [0002] The traditional eccentric link movement mechanism of the grooved needle used in the full-width weft inserting machine uses a conjugate cam and a crankshaft. The previous conjugate cam needs to process a curved extension on the cam to complete a reciprocating action. It is possible during the processing Bad spots appear, resulting in the inability to increase the speed, and the conjugate cam cannot guarantee a consistent size in processing, and the accumulated tolerance will become larger and larger, which will affect the speed of the machine. 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 to provide an eccentric link ...
