[0002] After the sheet-fed offset printing machine completes printing, the printed products are neatly collected on the paper pile table through the paper delivery mechanism. In order to ensure the neatness of the paper delivery pile, left and right paper aligning devices are required.

[0003] A Chinese patent discloses a double telescopic rod side paper aligning device for a printing machine (authorization announcement number CN220245045U). This patented technology can solve the problem that the existing side paper aligning rod is exposed outside the machine, which makes the appearance unsightly and workers are prone to bump into the side paper aligning rod when operating and walking, causing accidents.

[0004] However, due to the lack of a limiting structure after the existing paper alignment, the paper is easily affected by the external wind and blown up, resulting in scattering all over the ground, which increases the difficulty of subsequent work. In addition, the alignment device and the printer are mostly fixedly connected, making it inconvenient to carry. Summary of the invention

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In this embodiment, a double telescopic rod side paper aligning device for a printing press is provided, comprising a base 1 and a printer body 2, wherein a fixing groove is provided on the upper end surface of the base 1, an adjusting screw 11 is rotatably mounted on the left end surface of the fixing groove through a bearing, an adjusting motor 12 is mounted on the right end surface of the adjusting screw 11, an adjusting slider 13 is symmetrically screwed on the outer wall of the adjusting screw 11, a side plate 14 is mounted on the upper end surface of the adjusting slider 13, an outer cylinder is symmetrically mounted on the upper end surface of the base 1, an inner rod 15 is mounted in the outer cylinder by sliding fit, and the side plate 14 is mounted on the inner end of the inner rod 15, The printer body 2 is installed on the upper end surface of the base 1 by sliding cooperation. When the printer body 2 is working, it drives the printer body 2 to move backward to keep it away from the side plate 14, and the printed paper falls on the base 1. The adjusting motor 12 is started to drive the adjusting screw 11 to rotate. The adjusting screw 11 is symmetrical on the left and right and the threads are in opposite directions. The adjusting slider 13 moves inward, drives the inner rod 15 to move inward, and the side plate 14 moves inward to align the side edges of the paper to avoid the dislocation and confusion of the content of the data caused by the disorderly stacking of the paper, which requires the latter to be reassembled, increasing the difficulty of work.

[0022] The side plate 14 is an L-shaped structure, and an L-shaped frame 16 is rotatably installed on the upper end surface of the side plate 14 through a bearing. A spring rod 17 is installed on the top of the L-shaped frame 16, and a pressing plate 18 is installed at the bottom of the spring rod 17. During operation, when the paper alignment is completed, the L-shaped frame 16 is rotated 180 degrees, and the spring rod 17 drives the pressing plate 18 to move downward. The pressing plate 18 presses and fixes the paper to prevent the external wind from blowing the paper up and scattering it on the ground, thereby improving the diversity of the device.

[0023] The upper end surface of the L-shaped frame 16 is installed with an insertion rod 19 by means of threaded rotation, and the bottom of the insertion rod 19 is connected to the upper end surface of the pressure plate 18 by means of threaded rotation. When working, the insertion rod 19 limits and fixes the pressure plate 18 to prevent the spring rod 17 from driving the pressure plate 18 to press on the side plate 14, causing difficulty in rotating the L-shaped frame 16. When it is necessary to limit the pressure plate 18, the insertion rod 19 is rotated to keep it away from the pressure plate 18, and the operation is simple and convenient.

[0024] A through slot 21 is formed at the inner end of the side plate 14, and side blocks are symmetrically installed on the left and right side walls of the printer body 2. The side blocks are connected to the through slot 21 by sliding. When working, the side block structure is used to ensure the stability of the left and right side walls of the printer body 2 to avoid deviation when the printer body 2 is moved forward and backward.

[0025] A base frame 22 is installed at the bottom of the printer body 2, a first clamping head 23 is installed on the front end face of the base frame 22, and a clamping slot 24 is installed on the rear end face of the base 1 by clamping. When the printer body 2 is working, when the printer body 2 is not working, the printer body 2 is driven to move forward, and the first clamping head 23 is fixed to the base 1 by clamping, thereby ensuring the stability of the entire device, reducing the size of the device, and facilitating carrying.

[0026] The bottom of the base frame 22 is provided with a placement groove, in which a roller 25 is arranged. When working, the roller 25 structure is adopted, so as to further facilitate the staff to drive the printer body 2 to move forward and backward.

[0027] During specific operation, when the printer body 2 is working, it drives the printer body 2 to move backward, away from the side plate 14, and the printed paper falls on the base 1, and the adjustment motor 12 is started, driving the adjustment screw 11 to rotate. The adjustment screw 11 is symmetrical on the left and right and the thread directions are opposite. The adjustment slider 13 moves inward, driving the inner rod 15 to move inward, and the side plate 14 moves inward to align the side edges of the paper to avoid the messy stacking of papers, which may cause the content of the data to be misplaced and confused, so that it needs to be reassembled later, which increases the difficulty of work.

[0028] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
