In one embodiment, in order to receive the knitted fabric into a roll conveniently, the winding support 1 comprises upright posts 12 which are positioned above the winding roller group and positioned at two end sides of the winding roller group, a connecting shaft 8 is arranged between the upright posts 12, a fabric winding pipe 81 is sleeved on the periphery of the connecting shaft 8, and rolling balls 82 which are in rolling fit with the upright posts 12 are arranged at two ends of the connecting shaft 8. When a roll of knitted fabric 100 is completely wound, the connecting shaft 8 is pulled out of the fabric winding pipe 81 and reinserted into the unwound fabric winding pipe 81 for reuse. The connecting shaft 8 can be used as a shaft body with a certain weight, can be used as a balance weight during rolling, increases the friction force between the woven cloth roll 100 and the rolling roller group, and is more effective in skid resistance. The connecting shaft 8 can be in clearance fit with the cloth rolling pipe 81, the inner wall of the cloth rolling pipe 81 is kept tightly attached by using a balance weight, and the connecting shaft can also be in interference fit with the cloth rolling pipe 81, and meanwhile, the separation is considered, so that an expansion shaft, such as a threaded expansion shaft or an air expansion shaft, can be selected, and the interference fit relationship between the connecting shaft 8 and the cloth rolling pipe 81 can be conveniently released.

Instead of using the balance weight of the connecting shaft 8, a portable connecting shaft 8 can be used for the convenience of the worker, and meanwhile, the vertical column 12 is provided with a pressurizer 13 acting on two ends of the connecting shaft 8, as shown in fig. 5, and the output end of the pressurizer 13 abuts against two ends of the connecting shaft 8.

Because the pressurizer 13 needs to act on two ends of the connecting shaft 8, and when only one pressurizer 13 is arranged, a cross beam 14 can be connected to the output end of the pressurizer 13, two ends of the cross beam 14 respectively act on two ends of the connecting shaft 8 through the pressure lever 15, and in order to increase the balance stability of the movement of the cross beam 14, a slide rail can be arranged on the upright post 12, and two ends of the cross beam 14 are matched with the slide rail.

The presser 13 may always apply a force on the connecting shaft 8, and as the diameter of the knitted fabric roll 100 is larger, its own weight is larger, and if the presser 13 always keeps a constant force on the connecting shaft 8, for example, when a cylinder or a hydraulic cylinder is selected, it may increase the load of the driving motor 2 to be larger, which affects the normal rolling, so in one embodiment, a first detector 121 and a second detector 122 may be disposed on the column 12, the first detector 121 is configured to detect that the rolled knitted fabric roll 100 reaches a first predetermined diameter, so that the output end of the presser 13 is separated from the connecting shaft 8, the second detector 122 is configured to detect that the rolled knitted fabric roll 100 reaches a second predetermined diameter, so that the driving motor 2 stops working, and the second predetermined diameter is larger than the first predetermined diameter. The first detector 121 and the second detector 122 may be micro switches or photosensors.
