[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Reference Figure 1-4 The yarn feeding calibration device of a single-sided circular knitting machine shown in the figure includes a mounting plate 1, an L-shaped plate 2 is provided at the bottom of the mounting plate 1, and a guide wheel 3 and a conical ring 4 are respectively provided on the L-shaped plate 2 from top to bottom, and a hole corresponding to the position of the conical ring 4 is provided on the top of the mounting plate 1, so that the yarn passes through the hole, passes through the guide wheel 3, and then passes through the conical ring 4; and an L-shaped mounting frame 5 is provided on the back side of the L-shaped plate 2, and the top surface of the mounting frame 5 is connected to the bottom surface of the mounting plate 1; the speed changing mechanism provided on the mounting frame 5 is connected to the guide wheel 3, and is slidably connected to the speed changing mechanism through an adjusting member 10 provided on the upper side plate 15 of the mounting frame 5. The working state of the speed changing mechanism is switched by adjusting and moving the adjusting member 10, thereby adjusting the conveying efficiency of the guide wheel 3.

[0022] Speed changing mechanism: The driven cone 6 rotatably connected to the inner wall of the mounting frame 5 is coaxially connected to the guide wheel 3, and a driving cone 7 is rotatably connected below the driven cone 6 (on the outer wall of the mounting frame 5). The driving cone 7 and the driven cone 6 are connected by a transmission belt 8 (if the large diameter surface of the driving cone 7 is on the left, the large diameter surface of the driven cone 6 is opposite). Under the action of static friction, the driving cone 7 driven by the motor 9 drives the driven cone 6 to rotate through the transmission belt 8 to achieve drive, and in order to ensure that the transmission belt 8 does not fall off the cone during use, the adjustment member 10 on the side panel 15 limits the transmission belt 8, and the adjustment member 10 also performs the task of changing the position of the transmission belt 8.

[0023] Adjustment member 10: An inclined sliding hole 16 is provided on the outer wall of one set of side plates 15 (the inclined sliding hole 16 has the same inclination angle as the inclined surface of the driving cone 7, and its purpose is to facilitate the adjustment member 10 to be in a parallel relative distance with the two sets of cones when it moves). A connector is slidably connected in the sliding hole 16. In order to freely control the position of the connector, two sets of fixed plates are provided on the outer wall of the side plate 15. The fixed plates are rotatably connected with an adjustment rod 17. The adjustment rod 17 is threadedly connected to the connector, and the adjustment rod 17 is connected to the connector through the connection. The joint is limited by the sliding hole 16, so when the adjusting rod 17 is rotated, the connecting head moves back and forth in the sliding hole 16. In order to facilitate the use of the adjusting rod 17, a rotating head 18 is provided at the end of the adjusting rod 17, and the rotating head 18 is provided with an inner hexagonal groove for the use of the staff; a connecting plate 12 is provided on the inner wall of the connecting head, and two groups of limiting rods 11 are provided on the connecting plate 12 to form a movable limiting space. While limiting the transmission belt 8 first, it can also drive the transmission belt 8 to move, thereby achieving the purpose of linear adjustment of the speed of this design scheme.

[0024] The two sets of limit rods 11 are rotatably connected to the connecting plate 12 in order to reduce the friction force on the transmission belt 8 in the moving state during use.

[0025] Connector: The protrusion 13 is slidably connected in the sliding hole 16 and is restricted by the sliding hole 16. The inner wall of the protrusion 13 is connected to the connecting plate 12, and the outer wall is connected to the adjusting block 14. The adjusting block 14 is threadedly connected to the adjusting rod 17, thereby achieving the purpose of controlling the rotation of the entire adjusting member 10.

[0026] The working principle of this utility model is as follows: the yarn is passed through the hole on the mounting plate 1, and passes through the guide wheel 3, and passes through the holes on the conical ring 4 and the L-shaped plate 2. According to the processing situation, an inner hexagon is inserted into the rotating head 18, and the rotating head 18 is rotated to drive the adjusting rod 17 to rotate, thereby controlling the adjustment block 14 threadedly connected to the adjusting rod 17 to rotate, and driving the protrusion 13 to slide in the sliding hole 16 of the side plate 15, so that the connecting plate 12 drives the transmission belt 8 to move between the driving cone 7 and the driven cone 6 through the limit rod 11, changing the position of the transmission belt 8, thereby changing the transmission ratio, and making the rotation speed of the guide wheel 3 change linearly.
