Description

Technical Field

[0001] The utility model relates to the technical field of printing paper conveying, in particular to a printing feeding structure. Background Art

[0002] The printing feed structure is a mechanism installed in a printing press for conveying paper for printing. The mechanism is installed in the printing press to convey the printed paper, thereby facilitating the movement of the paper for printing. In the printing press, the performance of the printing feed structure directly determines the printing quality of the paper. Therefore, the printing feed structure is an indispensable component of the printing press and plays an important role in the field of printing technology.

[0003] There are various types of feeding structures for printing in the prior art. For example, CN115535668A discloses a printing paper conveying device, including a bracket, a first conveying plate and a second conveying plate are arranged at intervals above and below the bracket, an inclined plate is provided at one end of the first conveying plate, and the bracket is equipped with a first driving rod for driving the movement of paper on the inclined plate and a second driving rod for moving paper on the second conveying plate. The second driving rod is connected to a driving mechanism that drives it to rotate around its own axis. The first driving rod and the second driving rod are connected in transmission. The second driving rod is driven to rotate by the driving mechanism and then drives the first driving rod to rotate, thereby realizing the transmission of paper. In this device, paper is placed on the second conveying plate, and the transmission of paper is realized by the cooperation of the first driving rod and the second driving rod.

[0004] Although this structure can realize the transmission of paper, the above device still has huge defects during use. Since the paper is placed on the second transmission plate, and the second transmission plate has no structure to limit the paper, the stability of the paper on the second transmission plate is poor. When the paper is placed on the second transmission plate, it is easy to be affected by shaking and collision and become messy, which affects the paper during printing and causes certain inconveniences to the printing work.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figures 1 to 3 As shown, it is a structural schematic diagram of the feeding structure for printing in this embodiment. The feeding structure in this embodiment is installed in a printing press and is used to transport paper in the printing press to facilitate paper printing to improve the working efficiency of the printing press and ensure the printing quality of the printing press.

[0036] The feeding structure in this embodiment includes a fixed base 100, and a paper limiting member 200 is installed in the fixed base 100 for limiting the position of the paper, thereby ensuring the stability of the paper in the printing press to improve the printing quality of the printing press.

[0037] like Figure 1As shown, the fixed base 100 in this embodiment includes a fixed shell 101, and the paper limiter 200 is assembled in the fixed shell 101. In this embodiment, the fixed shell 101 is a U-shaped frame structure with an open top. The paper is placed on the paper limiter 200. The paper limiter 200 is used to limit the paper to ensure the neatness of the paper. In addition, a cover plate 102 is provided on the fixed shell 101, and a cavity is formed between the cover plate 102 and the fixed shell 101. The paper limiter 200 is installed in the cavity, and the paper is placed in the cavity to limit the paper by the paper limiter 200. In this embodiment, the end of the fixed shell 101 is also connected to a guide plate 103. When the printing machine is working, the paper on the paper limiter 200 is transported, and the paper is guided out of the feeding structure through the surface of the guide plate 103 to enter the printing machine for printing.

[0038] like Figure 4 as well as Figure 5 As shown, the paper limiting members 200 in this embodiment are symmetrically arranged, and the two paper limiting members 200 cooperate with each other to limit the paper. Figure 6 As shown, the paper limiters 200 in this embodiment cooperate with each other to limit the paper. It is worth noting that the paper limiters 200 in this embodiment are slidably installed in the fixed shell 101, and the two paper limiters 200 move so that the distance between the paper limiters 200 can be adjusted to accommodate the limitation of papers of different widths, thereby avoiding the problem of offset transmission of paper during printing.

[0039] In addition, if Figure 7 As shown, it is a structural schematic diagram of the paper limiter 200 in this embodiment. The paper limiter 200 in this embodiment includes a supporting plate 201. In this embodiment, the supporting plate 201 is an L-shaped structure, which is composed of a horizontal portion and a vertical portion. Paper is placed on the horizontal portion surface of the supporting plate 201, and different papers are limited in the horizontal direction by sliding between the supporting plates 201, thereby ensuring the stability of the paper.

[0040] In addition, the paper limiter 200 in this embodiment further includes a pressing plate 202, which is assembled on the vertical portion of the supporting plate 201 and presses against the surface of the paper, thereby preventing the paper from moving longitudinally and further ensuring the stability of the paper.

[0041] like Figure 8 , Fig. 9As shown, it is a schematic diagram of the structure of the mutual assembly between the supporting plate 201 and the pressure plate 202 in this embodiment. The horizontal part of the supporting plate 201 in this embodiment is connected with a fixing ear 201a, and the pressure plate 202 is fixedly connected with a clamping piece 202a, an opening is opened at the clamping piece 202a, and the lower surface of the clamping piece 202a is an arc-shaped structure. In this embodiment, when the pressure plate 202 is assembled on the supporting plate 201, the fixing ear 201a on the supporting plate 201 abuts against the lower surface of the clamping piece 202a and is guided into the opening through the arc-shaped structure of the lower surface of the clamping piece 202a, thereby assembling the pressure plate 202 on the supporting plate 201, and the assembly stability between the supporting plate 201 and the pressure plate 202 is guaranteed by the mutual cooperation between the clamping piece 202a and the fixing ear 201a.

[0042] Furthermore, in order to ensure the stability between the supporting plate 201 and the pressing plate 202, a hook 201b is connected to the side wall of the vertical portion of the supporting plate 201 in this embodiment, and Fig. 9 As shown, a columnar member 202b is connected to the side wall of the pressing plate 202. When the pressing plate 202 is assembled on the supporting plate 201, the hook 201b is hung on the columnar member 202b. The pressing action between the hook 201b and the columnar member 202b cooperates with the pressing action between the fixing ear 201a and the clamping member 202a, thereby further ensuring the stability of the pressing plate 202 on the supporting plate 201. In this embodiment, when a paper is placed on the horizontal part of the supporting plate 201, the paper limiting member 200 moves, and the two paper limiting members 200 The two rollers cooperate with each other to limit the horizontal direction of the paper, and the pressure plate 202 is pressed against the surface of the paper to limit the longitudinal direction of the paper, thereby ensuring the stability of the paper. It is worth noting that when the printing press is working, the paper is conveyed by the rotation of the roller and the friction with the paper. In this embodiment, the pressure plate 202 is pressed against the surface of the paper. When the roller rubs against the paper, it is used to offset the pressure of the pressure plate 202 on the paper, and the paper is conveyed by the rotation of the roller, thereby facilitating the printing press to convey the paper.

[0043] The assembly between the pressure plate 202 and the supporting plate 201 as described above is a fixed assembly, and the distance between the pressure plate 202 and the horizontal part of the supporting plate 201 is fixed. After the paper is consumed, it is difficult for the pressure plate 202 to press the paper anymore. In order to enable the pressure plate 202 to press the paper in real time, this embodiment also provides an assembly structure between the pressure plate 202 and the supporting plate 201, so that the pressure plate 202 can continuously press the paper.

[0044] like Fig.10As shown, it is a schematic diagram of the assembly structure of another embodiment of the pressure plate 202 and the supporting plate 201 in this embodiment. The pressure plate 202 in this embodiment is slidably assembled on the vertical part of the supporting plate 201. In this embodiment, a fixing hole 201c is opened on the side wall of the vertical part of the supporting plate 201, and a spring is connected in the fixing hole 201c. In addition, a guide member 202c is connected to the side wall of the pressure plate 202, and the guide member 202c is inserted into the fixing hole 201c and connected to the spring. In this embodiment, the pressure plate 202 is slidably connected to the side wall of the vertical part of the supporting plate 201 through the sliding assembly between the guide member 202c and the fixing hole 201c, thereby realizing the sliding assembly between the pressure plate 202 and the supporting plate 201. When the paper on the horizontal part of the supporting plate 201 is gradually consumed, the pressure plate 202 is moved downward by the action of the spring to always press on the surface of the paper, thereby ensuring the stability of the paper.

[0045] In this embodiment, the paper is placed between the supporting plates 201 in the paper limiter 200. The paper limiter 200 is moved to limit the horizontal direction of the paper. The pressing plate 202 is pressed against the surface of the paper to limit the longitudinal direction of the paper, thereby ensuring the stability of the paper. Then, when the printing press is working, the paper is output from the guide plate 103 one by one into the printing press when the paper is transported. In this embodiment, the paper limiter 200 ensures the stability of the paper, thereby ensuring the printing effect.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
