[0030] During normal weaving, there is a gap between the take-up roller 2 and the cloth pressing roller 1 for the cloth to pass through. The take-up roller 2 rotates, allowing the cloth to pass through the gap and driving the cloth pressing roller 1 to rotate. At this time, the pressure component 3 applies pressure to the middle of the round tube 101 through the roller 103 to make the round tube 101 pressurize the middle of the take-up roller 2, so as to increase the pressure and pressure effect of the cloth pressing roller 1 on the take-up roller 2, thereby increasing the pressure and pressure effect on the cloth. The pressure component 3 can adjust the pressure through the first screw 301.

[0031] As a preference, Figure 3 As shown, both sides of the roller 103 are provided with split pins 104, and the split pins 104 are installed on the pressure tube 102. By providing the split pins 104, the position of the roller 103 can be positioned.

[0035] The threaded position of the step nut 407 on the second screw 403 is adjusted by screwing the second screw 403, thereby adjusting the telescopic state of the second spring 404. At the same time, the contraction state of the second spring 404 is limited by setting the limit sleeve 406, so that the pressure acting on the winding roller 2 is within a certain range.

[0036] Preferably, a sleeve 408 is installed on the inner surface of the pressure cover 401, and the round tube 101 is rotatably connected to the sleeve 408; wherein the sleeve 408 is made of anti-friction material, has the characteristics of low friction coefficient and good wear resistance, and can reduce the friction force when the pressure tube 102 rotates.

[0037] Further, such as Figure 4-Figure 8 As shown, the above-mentioned winding and pressurizing device also includes a cloth pressing roller positioning mechanism 5, which includes a connecting rod 501, a rotating wheel 502, a handle 503, a first step screw rod 504, a second step screw rod 505, and a hexagonal screw rod 506.

Lifting is the lifting position of the cloth pressing roller 1 during manual cloth threading; when the first positioning hole 510 on the handle 503 is rotated to the positioning bead 509, the positioning bead 509 is partially embedded in the first positioning hole 510 to fix the handle 503, and the rotation position of the handle 503 is positioned. At the same time, the rotation of the handle 503 synchronously drives the rotating wheel 502 to rotate, and the rotating wheel 502 drives the connecting rod 501 to move downward. The connecting rod 501 causes the cloth pressing roller 1 to press the winding roller 2 downward through the pressure roller seat 402, which is the normal weaving pressure position. It should be noted that due to the interference of the roller shaft of the winding roller 2, the handle 503 cannot rotate 360°, and can only rotate clockwise and counterclockwise to a certain angle.

[0039] Preferably, the first step screw rod 504 is sleeved with a disc spring 514. The disc spring 514 is provided to play a role of pressing the handle 503.
