Abstract

The invention discloses a cloth delivery mechanism which comprises a swivel case and a cloth delivery mechanism. An inner rotor and an outer rotor rotate in a rotary chute in the swivel case, a spring is connected with a slide block, and a fixed semi-swivel and a sliding semi-swivel are arranged on the two sides of the swivel case body. The chute is connected to one end of a tooth rack, and cloth delivery tooth are installed on the top of the tooth rack. A coupler is connected to a cloth delivery motor shaft and the cloth delivery shaft, a first synchronizing wheel is installed on the cloth delivery shaft, and a second synchronizing wheel is installed on the outer end of the swivel case. A synchronous belt winds on the second synchronizing wheel and the first synchronizing wheel, and a needle distance adjusting shaft is connected with the swivel case, and a needle distance adjusting rocking bar is arranged on the needle distance adjusting shaft. The needle distance adjusting shaft connects the needle distance adjusting rocking bar and a needle distance base, and same forward and backward needle distances are ensured. Wrinkling and skidding of cloth delivery can be minimized, vibration and noise during delivering cloth at high speed can be reduced, and working rotating speed is increased. The cloth delivery mechanism is easy to realize modular production and assembly, and assembly efficiency is improved.

Description

technical field

[0001] The invention relates to the application field of a cloth feeding mechanism, in particular to a cloth feeding mechanism. Background technique

[0002] On sewing machines or other mechanical equipment related to cloth production, the existing cloth feeding mechanism has the following disadvantages:

[0003] (1) The cloth feeding mechanism basically adopts a two-axis drive with two degrees of freedom to realize the cloth feeding trajectory. In order to ensure the coordination and synchronization of the horizontal movement and the vertical movement, the installation and debugging are very cumbersome.

[0004] (2) The cloth feed dog of the existing mechanism always has an inclination angle during the movement process, which reduces the contact area between the tooth and the presser foot, not only reduces the cloth feeding force, but also tends to break when sewing thin materials. wrinkle.

[0005] (3) The cloth feeding mechanism includes many connecting ...
