[0025] Fixed clamping seat 4, there are four groups of fixed clamping seats 4 in total, the four groups of fixed clamping seats 4 are all arranged on the upper end face of the connecting base 7, and a positioning device 3 is arranged at the top of the fixed clamping seat 4;

[0026] Paper guiding roller 6, there are two groups of paper guiding rollers 6 in total, the two groups of paper guiding rollers 6 are both rotatably clamped inside the two groups of fixed clamping seats 4 at the front part, and a driving gear 1 is arranged on the side end face of the paper guiding roller 6, and a servo motor 5 is arranged on the side end face of the fixed clamping seat 4 opposite to the paper guiding roller 6.

[0027] The limiting device 2 includes a connecting baffle 22. At the top of the inner end face of the connecting baffle 22, a fixing chamfer 21 is provided, and at the center of the lower end face of the connecting baffle 22, a threaded guide base 23 is fixedly arranged.

[0028] The positioning device 3 includes a support base 33. At the side near the rear end face of the support base 33, a stepping motor 34 is provided, and at the output end of the stepping motor 34, a fixing lead screw 35 is fixedly arranged. The inner end face of the support base 33 is threadedly and slidably connected with a threaded sliding seat 31 through the fixing lead screw 35. At the upper end face of the threaded sliding seat 31, a three-axis cylinder 32 is fixedly arranged, and at the bottom of the three-axis cylinder 32, a positioning baffle 36 is fixedly arranged.

[0029] At the lower end face of the positioning baffle 36, a chamfer for positioning is provided. The chamfer at the bottom of the positioning baffle 36 can limit the longitudinal direction of the paper, thereby improving the stability of subsequent paper regularization.

[0030] The threaded guide base 23 is adapted to the bidirectional lead screw 8, and the connecting baffle 22 is slidably clamped on the inner end face of the connecting base 7 through the adaptation of the threaded guide base 23 to the bidirectional lead screw 8. The threaded connection between the threaded guide base 23 and the bidirectional lead screw 8 can facilitate the subsequent rapid adjustment of the spacing between the two groups of connecting baffles 22 for paper limiting, thereby improving the accuracy of paper guiding.

[0031] At the inner end face of the fixing chamfer 21, a guiding chute is provided, and the guiding chute does not contact the paper guiding roller 6. The guiding chute can provide a sufficient guiding basis for the paper guiding roller 6, thereby facilitating the subsequent rapid adjustment of the spacing of the connecting baffle 22 by the user.

[0032] Working principle: When collecting the printed paper, the operator can position the device in front of the paper outlet of the printing press. At the same time, the paper outlet is directly opposite to two groups of paper guide rollers 6, which facilitates the subsequent step-by-step export of the printed paper. Before paper collection, the operator can first adjust according to the width of the paper. The deceleration motor 9 can be started. At this time, the deceleration motor 9 can adjust the width of the two groups of threaded guide seats 23 and the connecting baffle 22 for paper limiting through the threaded connection with the two groups of threaded guide seats 23. After the adjustment is completed, the servo motor 5 can be started. The servo motor 5 can drive the two groups of paper guide rollers 6 to rotate in opposite directions through the transmission gear 1, so as to step by step import the printed paper between the two groups of connecting baffles 22. At the same time, when the paper inside the two groups of connecting baffles 22 reaches a certain thickness, the three-axis cylinder 32 can drive the alignment baffle 36 to move downward at this time. The alignment baffle 36 and the positioning chamfer at its bottom can gradually limit and press the paper with different longitudinal directions, so that the paper in the horizontal and vertical directions is kept regular, which facilitates subsequent collection. When the paper reaches a certain thickness, the three-axis cylinder 32 can press the paper through the alignment baffle 36. At the same time, the stepping motor 34 can drive the threaded slide seat 31, the alignment baffle 36 and the pressed paper to move outward synchronously through the fixed lead screw 35, so as to export the printed paper, which facilitates the subsequent cyclic paper collection operation for the remaining paper.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
