Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following detailed description is made with reference to the accompanying drawings and specific embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many other forms than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the one element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1-3, the embodiment discloses an improved yarn feeding tensioning adjusting device, which includes two bases 1 arranged at an interval, where the bases 1 are of a shell structure with an opening on the outer side, and the bases 1 are mainly used to be connected and fixed with an external frame to provide a bearing foundation for a yarn feeding roller.

Be equipped with 5 yarn rollers of sending between two bases 1, wherein 3

fixed rollers

2 and 2 movable roll 3, each roll body horizontal interval dislocation set for yarn snaking winding when advancing the yarn. Two ends of each roller body are connected with the base 1 through bearings.

Be equipped with first bar hole 11 and second bar hole 12 on the base 1, both mutually perpendicular for the position control of different parts equidirectional.

Two ends of the movable roller 3 are arranged in the first strip-shaped hole 11. Specifically, the two ends of the movable roller 3 are pivoted with the sliding blocks 7, the sliding blocks 7 are sleeved on an adjusting bolt 6, the adjusting bolt 6 is pivoted with the base 1, when the adjusting bolt 6 rotates, the self position of the adjusting bolt is kept still, the outer side end of the adjusting bolt 6 extends to the outer side of the base 1, and the adjusting bolt is fixedly connected with a knob. When the knob is rotated, the transverse movement of the slider 7 can be controlled by the rotation of the adjusting bolt 6, and the mounting position of the movable roller 3 is controlled, which can provide the adjustment capability for the yarn feeding tension.

A motor 4 is fixedly arranged on one base 1, the motor 4 is in transmission connection with each fixed roller 2 through a belt pulley and a belt to form a synchronous rotating mechanism, a tensioning adjusting wheel is arranged between a driving piece and each fixed roller 2, one end of the tensioning adjusting wheel is abutted to the belt, and the degree of tension of the belt can be adjusted.

Specifically, the output shaft of motor 4 has first belt pulley 51, and the end connection that fixed roll 2 is close to motor 4 one side has second belt pulley 52, is equipped with the multiunit on the first belt pulley 51 and is used for the heavy groove of establishing the belt around, and every heavy groove of group corresponds a second belt pulley 52.
