[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0022] A shutdown protection device for an automatic paper loader includes a base 1. The top of the base 1 is fixedly connected to a mounting frame 11 by bolts. The front surface of the mounting frame 11 is fixedly connected to a main drive motor 12 by bolts for driving a main winding roller 13 to rotate. The output shaft of the main drive motor 12 is coaxially connected to the main winding roller 13.

[0023] It should be supplemented that the top of the base 1 is fixedly connected to a support frame 14 by bolts to play a supporting role, and the top of the support frame 14 is fixedly connected to a top plate 15 by bolts.

[0024] Furthermore, a secondary drive motor 16 is fixedly connected to the front surface of the support frame 14 by bolts to drive the limit plate 17 to rotate. The output shaft of the secondary drive motor 16 is coaxially connected to the limit plate 17 to drive the drive bar 18 to rotate.

[0025] Specifically, a driving bar 18 is welded and fixed to the front end of the limit plate 17 to drive the auxiliary winding roller 19 to rotate. The front surface of the limit plate 17 is provided with an auxiliary winding roller 19, and a slot 191 is opened at the rear end of the auxiliary winding roller 19. The driving bar 18 is plugged into the inner wall of the slot 191.

[0026] As a preference of this embodiment, a protection mechanism 2 is provided above the base 1 , and the protection mechanism 2 includes a cylinder 21 , which is fixedly connected to the top of the top plate 15 by bolts to drive the moving frame 22 to move.

[0027] Specifically, the piston rod end of the cylinder 21 passes through the bottom of the top plate 15 and is fixed to the movable frame 22 by bolts. A limiting plate 23 is welded and fixed at the bottom of the movable frame 22 near the front side. The rear surface of the limiting plate 23 is in contact with the front end of the auxiliary winding roller 19 to limit the position of the auxiliary winding roller 19.

[0028] Specifically, an n-shaped mounting frame 24 is provided on the rear side of the limiting plate 23 , and a pressure roller 25 is rotatably connected to the rear surface of the inner wall of the n-shaped mounting frame 24 via a bearing to press the paper wound on the auxiliary winding roller 19 .

[0029] Specifically, the top of the n-type mounting frame 24 is symmetrically fixed with a slide rod 26 near the front and rear sides by bolts to limit the moving direction of the n-type mounting frame 24. The top of the slide rod 26 passes through the top of the moving frame 22 and is fixedly connected to the limiting plate 27 by bolts.

[0030] Specifically, a spring 28 is provided on the outer circumferential wall of the slide rod 26 , and one end of the spring 28 is fixedly connected to the top of the moving frame 22 to limit the moving direction of the n-shaped mounting frame 24 .

[0031] During specific use, when the main winding roller 13 or the auxiliary winding roller 19 cannot rotate due to a malfunction, the user first turns off the main drive motor 12 and the auxiliary drive motor 16. At this time, the outer wall of the pressure roller 25 presses the paper wound on the auxiliary winding roller 19, and the piston rod of the control cylinder 21 shortens, thereby driving the movable frame 22 to move upward, thereby driving the limit plate 23 to move upward;

[0032] The paper wound on the auxiliary winding roller 19 is disconnected from the paper wound on the main winding roller 13 until the piston rod of the cylinder 21 is retracted to the shortest and the rear surface of the limit plate 23 no longer fits the front end of the auxiliary winding roller 19. Then the auxiliary winding roller 19 can be removed.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
