[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] The utility model embodiment discloses a feeding device for paper printing and processing.
[0022] The utility model provides Figure 1-3 A feeding device for paper printing and processing shown in the figure comprises a bottom plate 1, two support plates 2 are fixedly arranged on the upper surface of the bottom plate 1, a mounting plate 3 is fixedly arranged between the two support plates 2, a support mechanism is arranged on the upper surface of the mounting plate 3 and a connecting plate 4 is connected to the mounting plate 3 through the support mechanism, two support rollers 5 are arranged above the connecting plate 4, a rotating rod 6 is fixedly sleeved inside each support roller 5, and the rod walls at both ends of each rotating rod 6 are rotatably connected to a fixing plate 7 fixedly connected to the connecting plate 4, two conical clamping blocks 8 are symmetrically arranged just above the two support rollers 5, and first L-shaped rods 9 are rotatably arranged on the opposite sides of the two conical clamping blocks 8, first through holes are opened inside the two support plates 2, and the two first L-shaped rods 9 are movably penetrated in the corresponding first through holes, a driving mechanism is arranged at the bottom of the mounting plate 3, and the two first L-shaped rods 9 are respectively connected to the corresponding driving mechanism through the driving mechanism, and the two support rollers 5 can be used to place and support the new paper roll before clamping, without the need for the staff to hold the new paper roll during the clamping process, thereby reducing the work intensity of the staff and improving the work efficiency.
[0023] like Figure 1 As shown, the supporting mechanism includes two groups of telescopic rods 10, each group of telescopic rods 10 is provided with two, and the two groups of telescopic rods 10 are symmetrically fixedly arranged on the lower surface of the connecting plate 4, and the other end of each telescopic rod 10 is fixedly connected to the mounting plate 3, and the rod wall of each telescopic rod 10 is movably sleeved with a spring 11, and the two ends of each spring 11 are fixedly connected to the surface of the mounting plate 3 and the connecting plate 4. By utilizing the provided springs 11, the connecting plate 4 can be squeezed by the elastic force of the springs 11, so that the surfaces of the two support rollers 5 are always in contact with the surface of the paper roll, thereby preventing the paper roll from becoming loose.
[0024] like Figure 1As shown, the driving mechanism includes a dual-axis motor 12 and two screw rods 13. The dual-axis motor 12 is fixedly arranged on the lower surface of the mounting plate 3. The two output ends of the dual-axis motor 12 are fixedly connected to the ends of the corresponding screw rods 13, respectively. Second through holes are provided inside the two support plates 2 and directly below the corresponding first through holes. Internally, the two second through holes are movably penetrated with internally threaded sleeves 14 that are threadedly sleeved with the rod walls of the corresponding screw rods 13. The ends of the two first L-shaped rods 9 that are away from the corresponding conical clamping blocks 8 are fixedly connected to the side walls of the corresponding internally threaded sleeves 14, respectively. By utilizing the dual-axis motor 12, the two screw rods 13 can be driven to rotate simultaneously during its operation, thereby driving the two internally threaded sleeves 14 to move simultaneously, thereby achieving the effect of adjusting the distance between the two conical clamping blocks 8, so that the new paper roll can be clamped after being placed above the two support rollers 5.
[0025] like Figure 1 As shown, an electric push rod 15 is fixedly provided on the upper surface of the mounting plate 3, and a second L-shaped rod 16 is fixedly connected to the output end of the electric push rod 15. A U-shaped rod 17 is fixedly provided at the center of the lower surface of the connecting plate 4. The horizontal end of the second L-shaped rod 16 is movably inserted in the inside of the U-shaped rod 17. By utilizing the set electric push rod 15, when replacing a new paper roll, the U-shaped rod 17 can be driven by the second L-shaped rod 16 to drive the connecting plate 4 to move downward, so that the axis of the new paper roll is consistent with the axis of the two conical clamping blocks 8, thereby facilitating the clamping of the two conical clamping blocks 8 with the ends of the new paper roll.
[0026] like Figure 1-3 As shown, the two conical clamping blocks 8 are both hard rubber blocks. By using the hard rubber blocks, the friction between the hard rubber blocks and the ends of the paper roll can be increased, and the stability after clamping can be ensured.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
