The cloth delivery speed of the circular knitting machine is uniform. The existing ones are usually equipped with tension rollers to sense the tension of the cloth to be rolled, thereby controlling the speed of the cloth winding motor. However, it is difficult to coordinate the tension sensor and the rotation speed of the cloth winding roller, resulting in the problem of uneven tightness of the rolled cloth. Utility Model Content

[0028] Reference Figure 1-5 As shown, a new type of cloth winding mechanism of a cloth winding machine includes a side plate 1, a cloth winding roller 2, a tension roller 3, a cloth pressing roller 4, a sliding assembly 5 and a cylinder 6. The cloth winding roller 2 is installed on the front side between the two side plates 1, the tension roller 3 is arranged between the two side plates 1 on the upstream side of the cloth winding roller 2, the cloth pressing roller 4 is arranged parallel to the side of the cloth winding roller 2 through the sliding assembly 5, the sliding assembly 5 is respectively fixed on the side plates 1 on both sides, and the cylinder 6 is connected to the sliding assembly 5.

[0029] The cloth-winding roller 2 realizes the winding of the cloth, and the cloth-pressing roller 4 applies pressure to the wound cloth, making the cloth flatter and stronger. The sliding component 5 can move the cloth-pressing roller 4 as the cloth roll increases. The cylinder 6 is used to control the pressure applied by the cloth-pressing roller 4 on the cloth roll in real time to avoid uneven pressure on the cloth roll due to sudden changes, which affects the cloth-winding quality on the one hand and affects the adjustment of the speed of the cloth-winding roller 2 by the motor on the other hand, applying uneven pulling force on the cloth, affecting the cloth quality; at the same time, since the tension roller 3 is used to sense the cloth tension to adjust the cloth-winding speed, it is difficult to keep the adjustment of the tension roller 3 and the motor speed consistent, which can easily damage the motor; and the cloth-pressing force is controlled by the cylinder 6, so that there is only a single factor influence between the control of the motor speed and the increase of the cloth roll, which is beneficial for the motor to control the cloth-winding speed, thereby improving the cloth-winding quality and increasing the service life of the motor.

[0030] Furthermore, the cylinder 6 is connected to a pressure regulating valve 61 .

[0031] The pressure regulating valve 61 is used to control the overall gas source pressure so that the pressure of the cylinder 6 remains within a certain pressure range.

[0032] Furthermore, a constant pressure valve 62 is provided between the cylinder 6 and the pressure regulating valve 61 .

[0033] The constant pressure valve 62 is used to further control the pressure of the cylinder 6 so that the cylinder 6 always maintains a stable pressure, that is, the pressure applied by the cloth pressing roller 4 to the cloth roll is maintained at a relatively constant value and will not change due to the increase of the cloth roll.

[0034] Furthermore, the pressure value of the pressure regulating valve 61 is controlled at 0.3-0.35 MPa.

[0035] Within this pressure value, the cloth pressing roller 4 can apply a relatively ideal pressure to the cloth roll to ensure the cloth roll quality.

[0036] Furthermore, the pressure value of the constant pressure valve 62 is controlled within a range of 0.01-0.05 MPa.

[0037] Within this constant pressure value, the incoordination caused by the lag in the adjustment of the tension roller 3 and the motor speed due to the increase in the cloth roll can be compensated, making the adjustment of the motor speed smoother, the cloth winding speed more balanced, and better matching with the speed of the circular knitting machine.

[0038] Furthermore, the sliding assembly 5 is provided with a slide rail 51, a slider 52 and a mounting frame 53, the slide rail 51 is respectively provided on the two side plates 1, the slider 52 is provided on the slide rail 51, the mounting frame 53 is provided on the slider 52, and the cloth pressing roller 4 is provided between the two mounting frames 53.

[0039] Furthermore, two cloth pressing rollers 4 are provided in parallel.

[0040] The two cloth pressing rollers 4 can be used in more diverse cloth winding modes to match the arrangement of more front and rear structures.

[0041] Furthermore, the cloth rolling roller 2 is provided with a motor (not shown), which is fixed on one side plate 1 and linked with the cloth rolling roller 2 .

[0042] Furthermore, the motor is a servo motor.

[0043] Furthermore, the motor is provided with a reducer.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
