Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an improved rewinding machine. Background Art

[0002] The rewinding machine is a kind of equipment commonly used in yarn production for yarn transfer. The purpose is to transfer the yarn originally wound on a smaller yarn tube to a larger yarn tube, which is suitable for subsequent yarn production.

[0003] By winding the yarn on the yarn bobbin onto another yarn bobbin, the diameter of the wound yarn will gradually become smaller, while the diameter of the other wound yarn will gradually become larger. Then, under the condition of unchanged rotation speed, the diameter of the yarn on the wound yarn bobbin will become larger, and the linear speed will gradually increase. On the contrary, the linear speed of the yarn on the other yarn bobbin will be affected due to its smaller diameter, which can easily make the yarn too tight and cause the yarn to break.

The card plates 32 on different groups of processing racks 1 are all driven.

[0027] The control unit 6 includes a U-shaped sheet metal 61 and a control threaded shaft 63 capable of twisting;

[0028] The U-shaped sheet metal 61 is fixed on the outside of the frame plate 2, a threaded sleeve 62 is fixed on the outside of the U-shaped sheet metal 61, a control threaded shaft 63 is sleeved into the threaded sleeve 62 and is threadedly connected with the threaded sleeve 62, and the end of the control threaded shaft 63 is provided with a metal sheet 64;

[0029] The end of the limiting shaft 4 at the lower end is provided with a notch 41, in which a rubber layer 42 is embedded. The rubber layer 42 is squeezed with the metal sheet 64. The squeezing force of the rubber layer 42 and the metal sheet 64 is different, and the size of the friction also changes, thereby achieving the adjustment of the resistance.
