Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present embodiment provides a cloth stretching apparatus, which includes a box 1, and a manual adjusting mechanism 2, a guiding mechanism 3, an automatic adjusting mechanism 4, and a cloth discharging mechanism 5 are sequentially disposed on the box 1 along a moving direction of a cloth 6.

In order to realize automatic adjustment of the tensile tension of the fabric, please refer to fig. 1-3, in this embodiment, the automatic adjustment mechanism 4 includes a self-adjusting roller 44 parallel to the axial direction of the hand-adjusting roller 22, an articulated rod 42 located at two ends of the self-adjusting roller 44, and a fixed rod 41 articulated with the articulated rod 42, wherein the self-adjusting roller 44 is rotatably connected with the articulated rod 42, the fixed rod 41 is fixedly arranged on the box body 1, a first torsion spring is arranged between the articulated rod 42 and the fixed rod 41, and two force-bearing ends of the first torsion spring are respectively fixedly arranged on the articulated rod 42 and the fixed rod 4; the cloth 6 is pressed on the self-adjusting roller 44, and when no external force is applied, the first torsion spring keeps the included angle between the hinged rod 42 and the fixed rod 41 unchanged; when the pressure of the cloth 6 acting on the surface of the self-adjusting roller 44 is increased, the self-adjusting roller 44 is under the pulling force of the cloth 6 to drive the hinge rod 42 to rotate, and at the moment, the first torsion spring between the hinge rod 42 and the fixed rod 41 is tightened; when the pressure of the cloth 6 acting on the surface of the self-adjusting roller 44 is reduced, the hinge rod 42 is driven to rotate reversely under the action of the first torsion spring, and the tensile tension of the cloth is automatically adjusted.

In this embodiment, in order to make the rotation of the hinge rod 42 more stable, the automatic adjustment mechanism 4 further includes a waist-shaped groove 411 provided on the fixing rod 41, the hinge rod 42 is hinged with a connecting rod 43, a sliding rod 431 is provided on the connecting rod 43, and the sliding rod 431 is slidably connected with the inner wall of the waist-shaped groove 411; a second torsion spring is arranged between the connecting rod 43 and the hinge rod 42, and two stress ends of the second torsion spring are fixedly arranged on the connecting rod 43 and the hinge rod 42 respectively; when the tension is increased, the self-adjusting roller 44 is pushed to move towards the direction close to the box body 1 by the cloth 6 abutting against the self-adjusting roller 44, so that the hinge rod 42 rotates, the slide rod 431 on the connecting rod 43 is pushed to rotate in the waist-shaped groove 411, and the slide rod 431 moves towards the direction close to the box body 1; when the tension force is reduced, under the action of the first torsion spring and the second torsion spring, the sliding rod 431 moves towards the direction far away from the box body 1, and meanwhile, the hinge rod 42 rotates reversely to push the self-adjusting roller 44 to move towards the direction far away from the box body 1, so that the tension force of the cloth 6 is increased.

In order to manually adjust the tension of the fabric 6, please refer to fig. 1-3, in this embodiment, an adjusting sliding cavity 11 is formed in an end surface of the box body 1, linear sliding rails 12 are arranged on two side walls of the adjusting sliding cavity 11, the manual adjusting mechanism 2 includes a manual adjusting roller 22 and electric sliders 21 located at two ends of the manual adjusting roller 22, the electric sliders 21 are slidably connected with the linear sliding rails 12, and the manual adjusting roller 22 is rotatably connected with the electric sliders 21; one end of the sliding rod 431 is in threaded connection with the connecting rod 43, the other end of the sliding rod 431 is provided with a butting block, and the fixing rod 41 is positioned between the threads of the sliding rod 431 and the butting block;

when the tension needs to be increased, the pressure between the connecting rod 43 and the fixed rod 41 can be increased only by rotating the sliding rod 431 and moving the abutting block to the direction close to the connecting rod 43, so that the friction between the connecting rod 43 and the fixed rod 41 is increased, at this time, because the rotation of the hinge rod 42 needs to overcome the friction between the connecting rod 43 and the fixed rod 41, the self-adjusting roller 44 needs to bear higher pressure to drive the hinge rod 42 to rotate, and the tension of the cloth 6 is manually adjusted (increased); if the pulling force is insufficient, only the height of the electric slider 21 needs to be adjusted to increase the distance between the manual adjusting roller 22 and the self-adjusting roller 44, thereby increasing the tension of the cloth 6, and it is noted that in order to make the adjustment range larger, it is preferable to move the manual adjusting roller 22 to the position closest to the self-adjusting roller 44.

Referring to fig. 1 and fig. 2, in order to adjust an included angle between the cloth 6 and the self-adjusting roller 44 and an included angle between the cloth 6 and the hand-adjusting roller 22, in this embodiment, the guide mechanism 3 includes a guide roller 32 and first positioning plates 31 located at two ends of the guide roller 32, and the guide roller 32 is rotatably connected to the first positioning plates 31; the number of the guide rollers 32 is two, the axes of the two guide rollers 32 are parallel and are positioned on the same vertical plane, a gap is reserved between the two guide rollers 32, and the cloth 6 passes through the gap between the two guide rollers 32.
