[0026] Embodiment 1:

[0027] The utility model provides a cloth expansion rack, which is convenient for storing cloth and can provide tensioning force when the cloth is sent into a machine for printing and dyeing, so as to expand the cloth and improve the use efficiency.

[0028] Provides such as Figure 1-2 A cloth tensioning frame shown in the figure includes: a support frame 1, a rotating shaft 2 and a clamping device 3, wherein two clamping devices 3 are arranged at both ends of the support frame 1, and both ends of the rotating shaft 2 are inside the clamping device 3. The clamping device 3 is used to provide pressure and friction for the rotating shaft 2 to reduce the rotational inertia of the rotating shaft. A connecting leg 13 is arranged at the bottom of the support frame 1, and a connecting rod 15 is arranged at the top of the support frame 1.

[0029] The clamping device 3 includes a fixed block 31, a pressing plate 32 and a knob 33. Two fixed blocks 31 are provided and fixedly mounted on the support frame 11. A threaded hole 311 is provided on the fixed block 31. Positioning holes 321 are provided at both ends of the pressing plate 32. A screw rod 331 is provided below the knob 33. The screw rod 331 passes through the positioning hole 321 on the pressing plate 32 and is connected to the threaded hole 311 by thread. The pressing plate 32 includes a steel plate 322 and an elastic band. The steel plate 322 is fixed on the elastic band 323. The positioning holes 321 are at both ends of the elastic band 323. The steel plate 322 is arc-shaped. The material of the steel plate 322 is spring steel. The material of the elastic band 323 is polyurethane. The fixed block 31 is on both sides of the rotating shaft 2, and the pressing plate 32 is pressed on the rotating shaft 2. The arc-shaped steel plate 322 matches the outer diameter of the rotating shaft 2. The knob 33 is rotated to make the pressing plate 32 press the rotating shaft 2.

[0030] The bottom of the support frame 11 is provided with a support rod 11 and a moving wheel 12, which are respectively arranged at both ends of the support frame 11, and the height of the support rod 11 is the same as the height of the moving wheel 12. The support rod 11 and the moving wheel 12 are at the same height, and the support frame 11 can be kept stable when not moving, and one end of the support rod 11 can be lifted and moved by the moving wheel 12 when moving.

[0031] The bottom of the support frame 11 is provided with a connecting leg 13, and the bottom of the connecting leg 13 is provided with a limiting cover 14. The top of the support frame 11 is provided with a connecting rod 15, and the connecting rod 15 and the connecting leg 13 are on the same vertical line, and the connecting rod 15 cooperates with the limiting cover 14. The height of the connecting leg 13 is lower than the height of the support rod 11.

[0032] Working principle: When not moving, the support rod 11 and the moving wheel 12 are at the same height to maintain the stable support of the support frame 11. When moving, one end of the support rod 11 is lifted and the position of the support frame 11 is moved by the moving wheel 12.

[0033] The fixing block 31 is on both sides of the rotating shaft 2, and the pressing plate 32 is pressed on the rotating shaft 2. The arc-shaped steel plate 322 matches the outer diameter of the rotating shaft 2. The knob 33 is rotated to make the pressing plate 32 press the rotating shaft 2. When the cloth enters the machine, the machine generates a pulling force on the cloth. The pressure and friction of the pressing plate 32 make the rotating shaft 2 provide an opposite tension force, so that the cloth is expanded. When the machine stops suddenly, the pressure and friction of the pressing plate 32 reduce the influence of inertia of the rotating shaft 2, and the rotation stops quickly, so that the cloth remains in an expanded state.

[0034] like Figure 3 As shown, a plurality of support frames 11 can be stacked by connecting rods 15 and connecting legs 13, and the limiting cover 14 cooperates with the connecting rods 15 to limit the connecting rods 15 so as to keep the support frames 11 stable.
