Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing guiding equipment, in particular to a printing guiding mechanism. Background Art
[0002] A printing press is a machine used for printing text and images. Modern printing presses generally consist of mechanisms such as plate loading, ink coating, impression, and paper feeding. Its working principle is as follows: First, the text and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with text and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates to reproduce the same printed matter as the printing plate.
[0003] However, in the prior art, when the existing printing press is in normal use, with the help of the printing paper guiding shaft and the upper limit ring thereon, it plays a guiding role for the conveyed printing paper to prevent the printing paper from shifting during the conveying process. Most of the limit rings on the printing paper guiding shaft are fixedly arranged, resulting in the inability to adjust the limit ring according to the width of the printing paper, and the practicability is relatively low. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art: Most of the limit rings on the printing paper guiding shaft are fixedly arranged, resulting in the inability to adjust the limit ring according to the width of the printing paper, and the practicability is relatively low.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A printing guiding mechanism, including a bottom plate, the upper surface of the bottom plate is fixedly connected with a support frame, and the top of the support frame is rotatably connected with a printing paper guiding shaft. Both ends of the outer surface of the printing paper guiding shaft are penetrated and connected with limit rings. The lower end of the limit ring is fixedly connected with a sliding plate, and the sliding plate is slidably connected with the bottom plate. A lead screw is rotatably penetrated through the sliding groove position of the sliding plate in the bottom plate, and the lead screw is threadedly connected with the sliding plate. One end of the lead screw is penetrated and fixed with a gear, and the gear is movably connected by embedding in the bottom plate. The gears in the same row are meshed with each other.
[0006] As a preferred embodiment, the inner diameter of the limit ring is adapted to the cross-sectional area of the printing paper guiding shaft.
[0007] As a preferred embodiment, one side surface of the bottom plate is fixedly connected with a motor, and the output end of the motor is fixedly connected with one end of the lead screw.
[0008] As a preferred embodiment, a protective cover is fixedly connected to the surface of the bottom plate near the position where the gears are located.
[0009] Compared with the prior art, the advantages and positive effects of the utility model are as follows:
[0010] In this utility model, by rotating the lead screw on one side, with the help of the rotational movement between the gears in the same row, the lead screw on the other side rotates in the opposite direction relatively, so that the sliding plates at both ends of the bottom plate move towards the middle of the bottom plate, thereby changing the distance between the limiting rings, so that the limiting rings can be adjusted according to the width of the printing paper, improving the practicability of itself.

[0016] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.
[0017] Embodiment 1
[0018] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: a printing guiding mechanism, including a bottom plate 1, on the upper surface of the bottom plate 1 is fixedly connected with a support frame 2, and at the top of the support frame 2 is rotatably connected with a printing paper guiding shaft 3. Both ends of the outer surface of the printing paper guiding shaft 3 are penetrated and connected with a limiting ring 4. The cooperation of the printing paper guiding shaft 3 and the limiting ring 4 plays a guiding role for the printing paper passing through on the printing paper guiding shaft 3. The lower end of the limiting ring 4 is fixedly connected with a sliding plate 5, and the sliding plate 5 is slidably connected with the bottom plate 1. A lead screw 6 is rotatably penetrated through the chute position of the sliding plate 5 in the bottom plate 1, and the lead screw 6 is threadedly connected with the sliding plate 5. One end of the lead screw 6 is penetrated and fixed with a gear 7, and the gear 7 is embedded and movably connected in the bottom plate 1. The gears 7 in the same row are meshed with each other. With the help of the gear 7, by rotating one of the lead screws 6, the other lead screw 6 can be made to rotate in the opposite direction relatively, so that the sliding plates 5 at both ends of the bottom plate 1 move towards the middle of the bottom plate 1, achieving the purpose of changing the distance between the limiting rings 4.
[0019] Embodiment 2
[0020] As Figures 1-3 shown, the inner diameter of the limiting ring 4 is adapted to the cross-sectional area of the printing paper guiding shaft 3. This can effectively reduce the resistance caused by the limiting ring 4 to the printing paper guiding shaft 3 during its rotation, making the rotation of the printing paper guiding shaft 3 smoother. One side surface of the bottom plate 1 is fixedly connected with a motor 8, and the output end of the motor 8 is fixedly connected with one end of the lead screw 6. With the help of the motor 8, it is convenient to control the rotation of one of the lead screws 6. A protective cover 9 is fixedly connected to the surface of the bottom plate 1 near the position where the gear 7 is located. The protective cover 9 protects the gear 7 and effectively prevents it from being damaged by external adverse effects.
[0021] Working principle:
[0022] As Figures 1-3 shown, when the present utility model is in use, if the user wants to adjust the distance between the limiting rings 4 to adapt to the width of the printing paper, first control the motor 8 to start. The motor 8 drives the rotation of one of the lead screws 6, and then drives the rotation of the gears 7 in the same row, making the other lead screw 6 rotate in the opposite direction relatively. Through the rotation of the two lead screws 6, the sliding plates 5 at both ends of the bottom plate 1 gradually move towards the middle of the bottom plate 1. The movement of the sliding plates 5 drives the limiting rings 4 to move towards the middle of the printing paper guiding shaft 3, achieving the purpose of changing the distance between the limiting rings 4, so that the distance between the limiting rings 4 can be adjusted according to the width of the printing paper.
[0023] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
