Description

Technical Field

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

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by the printing press. Then, the ink is directly or indirectly transferred to paper or other substrates, thereby replicating the same printed product as the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] When a printing press is in use, paper needs to be added to the printing press so that the printing press can print images or text on the paper. Therefore, when the printing press is in use, the setting of a paper feeding mechanism is essential. In the paper feeding mechanism, the paper raw material is usually wound around a material roller, and a rotating shaft is further installed inside the material roller. The material roller is driven to rotate by the rotation of the rotating shaft, thereby achieving the purpose of conveying the paper. After searching, it is found that the above method still has some problems that need to be improved. For example, when the material roller is installed on the mounting shaft, the side plate is usually fixed to the bottom box by bolts. When loading, the side plate needs to be disassembled, and the waste material roller is further removed and a new material roller is installed. This method is time-consuming and labor-intensive, resulting in low printing efficiency. For this reason, we propose a printing press feeding structure to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a feeding structure for a printing press, which has the advantage of convenient replacement of the material roller, and solves the problem that the traditional method of replacing the material roller requires disassembly of the side plate, resulting in low replacement efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a printing press feeding structure comprises a bottom box, a fixed plate, and a side plate; a mounting shaft is fixed inside the fixed plate through a bearing, a first motor is fixed on the upper surface of the bottom box, a driving sprocket is fixed on the output shaft of the first motor, a driving chain is connected to the outer surface of the driving sprocket, and one end of the driving chain away from the driving sprocket is connected to the driven sprocket; an adjustment component is arranged inside the bottom box;

[0006] The adjustment component includes a second motor fixed at the right end of the bottom box, the output shaft of the second motor is fixed with a threaded rod, the outer surface of the threaded rod is threadedly connected with a movable plate, the adjustment component also includes a limit rod fixed between the left and right side walls of the bottom box, the outer surface of the limit rod is slidably connected with a slider.

[0007] Furthermore, the bottom box is a rectangle with a hollow interior and a missing bottom surface, and two long holes are provided on the upper surface of the bottom box, and the two long holes are respectively used for the movable plate and the limiting rod to move.

[0008] Furthermore, the upper surfaces of the movable plate and the sliding block are fixed to the lower surfaces of the side plates.

[0009] Furthermore, a ring-shaped mounting hole is provided at the right end of the side plate, a fixing ring is fixed inside the mounting hole, a mounting groove is provided inside the fixing ring, a plurality of balls are arranged in the mounting groove, the fixing ring is ring-shaped, and two blocks are fixed on the inner wall of the fixing ring.

[0010] Furthermore, the stopper is fitted with the ball, the mounting groove is annular, and a plurality of the ball bearings are distributed in annular shape inside the mounting groove.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. The feeding structure of the printing press moves the side plate to the left, thereby suspending the mounting shaft, further removing the material roller installed on the outer surface of the mounting shaft, and installing a new material roller. By moving the side plate to the left, the installer can have a larger operating space, and the waste material roller can be easily removed, thereby improving the efficiency of the installer in installing and removing the material roller.

[0013] 2. The feeding structure of the printing press can avoid the problem of the installation shaft being stuck and the movement of the side plate being restricted by arranging a plurality of balls in the fixed ring when the installation shaft is separated from the side plate, thereby providing a guarantee for the movement of the side plate.

[0020] See also Figure 1 A printing press feeding structure in this embodiment includes a bottom box 1, a fixed plate 2, and a side plate 3. The bottom box 1 is a rectangle with a hollow interior and a missing bottom surface. Two long holes are provided on the upper surface of the bottom box 1; a mounting shaft 4 is fixed to the interior of the fixed plate 2 through a bearing, a first motor 5 is fixed to the upper surface of the bottom box 1, a driving sprocket 6 is fixed to the output shaft of the first motor 5, a driving sprocket 6 is transmission-connected to the outer surface of the driving sprocket 6 with a transmission chain 7, and one end of the transmission chain 7 away from the driving sprocket 6 is transmission-connected to a driven sprocket 8; an adjusting component is provided in the bottom box 1.

[0021] By moving the side plate 3 to the left, the mounting shaft 4 can slide out through the ball 11, so that the mounting shaft 4 is vacated, and the material roller fixed on the outer surface of the mounting shaft 4 can be removed and replaced with a new material roller, thereby improving the efficiency of the installer in installing and removing the material roller.

[0022] During operation, the output shaft of the first motor 5 rotates, driving the driving sprocket 6 fixed on the output shaft of the first motor 5 to rotate. During the rotation of the driving sprocket 6, the transmission chain 7 installed on the outer surface of the driving sprocket 6 drives the driven sprocket 8 to rotate, so that the driven sprocket 8 drives the installation shaft 4 to rotate, and the installation shaft 4 drives the material roller installed on its outer surface to rotate, so that the paper on the material roller is transported to the printing press for printing.

[0023] See also Figure 2 and Figure 3 In order to fix the mounting shaft 4, an annular mounting hole is opened at the right end of the side plate 3 in this embodiment, a fixing ring 9 is fixed inside the mounting hole, a mounting groove 10 is opened inside the fixing ring 9, the mounting groove 10 is annular, a plurality of balls 11 are arranged in the mounting groove 10, and the plurality of balls 11 are distributed in annular shape inside the mounting groove, the fixing ring 9 is annular, and two blocks 12 are fixed on the inner wall of the fixing ring 9, and the blocks 12 fit the balls 11.

[0024] When the side plate 3 moves to the left, the mounting shaft 4 can be smoothly separated from the side plate 3 by the action of the plurality of balls 11 , and after the material roller on the mounting shaft 4 is replaced, the mounting shaft 4 can also be smoothly inserted into the fixing ring 9 .

[0025] See also Figure 4 In order to drive the side panel 3 to move to the left, the adjustment component in this embodiment includes a second motor 13 fixed to the right end of the bottom box 1, and the output shaft of the second motor 13 is fixed with a threaded rod 14, and the outer surface of the threaded rod 14 is threadedly connected with a movable plate 15.
