Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to an easily adjustable paper positioning structure for printing presses. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, paper feeding, and folding. Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the areas of the printing plate containing the text and images, either manually or by the printing press itself. The ink is then directly or indirectly transferred to paper or other printing substrates such as paper, textiles, metal plates, plastics, leather, wood, glass, and ceramics, thereby reproducing a printed product identical to the printing plate.

[0003] Chinese Utility Model Patent Publication No. CN 220282930 U discloses a universal limiting structure for a printing press. This universal limiting structure for printing presses includes a positioning plate, a width adjustment plate, a limiting disc, and a guide plate, which can effectively form a limiting structure where the paper passes. This facilitates the positional limitation of the paper on both sides when it is conveyed by the paper conveyor belt, and allows the paper to enter the lower part of the printing press body along the prescribed position. This allows the printing mechanism in the printing press body to accurately print the text or pattern onto the paper, achieving accurate printing. However, this universal limiting structure for printing presses lacks an adjustment mechanism, making it difficult to achieve vertical and horizontal displacement. This results in the overall positioning structure being difficult to adjust according to different paper sizes during use, leading to poor versatility of the overall positioning structure. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an easily adjustable paper positioning structure for printing presses, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: an easily adjustable paper positioning structure for a printing press, including a fixed frame, a mounting frame and a limiting component slidably connected to the fixed frame away from the center, a groove being formed on the outer surface of the mounting frame, a mounting plate being fixedly installed at the other end of the mounting frame away from the fixed frame, a reinforcing rib being fixedly installed at the connection between the mounting plate and the mounting frame, a spring being fixedly installed on the outer surface of the mounting plate, a top block being fixedly installed at the other end of the spring away from the mounting plate, a vertical displacement component slidably connected to the groove being fixedly installed at the end of the top block near the spring, and a horizontal displacement component and a positioning component being provided at the other end of the vertical displacement component away from the mounting frame.

[0006] Preferably, the vertical displacement component includes a vertical displacement column and a limiting sleeve. The outer surface of the vertical displacement column is provided with a moving groove and a moving groove. The moving groove is adapted to the horizontal displacement component. The limiting sleeve penetrates the horizontal displacement component and the moving groove and extends to its outer surface.

[0007] Through the above technical solution, the vertical displacement component can be flexibly adjusted in the vertical direction to meet the positioning requirements of different paper sizes. The first moving slot and the first limiting sleeve ensure the stability of the connection between the horizontal displacement component and the vertical displacement column, while the second moving slot allows the horizontal displacement component to be finely adjusted, improving the positioning accuracy.

[0008] Preferably, the horizontal displacement component includes a horizontal displacement column and a limiting sleeve 2. The outer surface of the horizontal displacement column is provided with a moving groove 3 and a moving groove 4. A fixing block is fixedly installed on the inner surface of the horizontal displacement column. The fixing block is adapted to the vertical displacement component.

[0009] Through the above technical solutions, the horizontal displacement component realizes the adjustment function of the positioning structure in the horizontal direction. Combined with the vertical displacement component, the position of the positioning structure can be flexibly adjusted in a two-dimensional plane. The fixed block ensures the connection stability between the horizontal displacement column and the vertical displacement column. The moving slot three, the limiting sleeve two, and the moving slot four provide convenience for the installation and movement of the positioning component, further improving the flexibility and accuracy of positioning.

[0010] Preferably, the second limiting sleeve passes through the third moving groove and the positioning component and extends to their outer surface, and the fourth moving groove and the positioning component are slidably connected.

[0011] Through the above technical solution, the cooperation of the limiting sleeve two and the moving slots three and four enables the positioning component to flexibly adjust its position and fix it on the horizontal displacement column, which facilitates precise positioning adjustment according to the actual situation of the paper and ensures the accuracy of positioning.

[0012] Preferably, the positioning component includes a positioning strip, an insert is fixedly mounted on the outer surface, and a fixing bolt and a contact piece are provided through the other end of the positioning strip away from the insert.

[0013] Through the above technical solution, the design of the positioning component can position the paper. The insert facilitates the installation and removal of the positioning strip and the horizontal displacement column. The fixing bolt can ensure that the position of the positioning strip is fixed. When the contact piece contacts the paper, it can better realize the positioning function, thus improving the stability and accuracy of paper positioning.

[0014] Preferably, the limiting component includes a limiting frame one and a limiting frame two, and mounting bolts are provided at the four corners of the limiting frame one and the limiting frame two. The mounting bolts pass through the limiting frame one and the limiting frame two and extend to their outer surfaces.

[0015] Through the above technical solution, the limiting component can limit the mounting frame and other components, preventing them from sliding or shaking excessively on the fixed frame, ensuring the stability of the entire positioning structure. The fixing method of the mounting bolt makes the installation and disassembly of the first limiting frame and the second limiting frame convenient and easy to adjust according to the actual situation.

[0016] Preferably, the outer surface of the limiting frame two is provided with a slot, the inner surface of the slot is fixedly installed with a locking post and a sliding frame, and the inner surface of the sliding frame is rotatably installed with a sliding roller.

[0017] Through the above technical solution, the card column can position and limit the component to a certain extent, and the combination of the sliding frame and the sliding roller reduces the friction when the component slides. When in contact with the paper, it can reduce the friction and improve the smoothness of printing. At the same time, it also reduces the wear of the component and the limiting frame and extends the service life of the equipment.

[0018] Compared with the prior art, this utility model provides an easily adjustable paper positioning structure for printing presses, which has the following advantages:

[0019] 1.

The design of the moving groove and limiting sleeve ensures the accuracy of adjustment. The positioning components can be flexibly adjusted and fixed on the horizontal displacement column, further ensuring accurate paper positioning and improving its versatility.

[0020] 2. This easily adjustable printing press paper positioning structure features reinforcing ribs between the mounting plate and the mounting frame to enhance connection strength. Limiting components prevent excessive sliding or shaking of the mounting frame and other parts, ensuring the stability of the entire positioning structure. Mounting bolts facilitate the installation and disassembly of limit frame one and limit frame two. The positioning strip is connected to the horizontal displacement column via insert strips, making installation and replacement convenient and reducing maintenance difficulty.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides an easily adjustable paper positioning structure for a printing press, including a fixed frame 1. A mounting frame 2 and a limiting component 11 are slidably connected to the fixed frame 1 away from the center. A groove 7 is provided on the outer surface of the mounting frame 2.

A horizontal displacement component 9 and a positioning component 10 are provided at the other end of the vertical displacement component 8 away from the mounting frame 2.

[0031] Specifically, the vertical displacement component 8 includes a vertical displacement column 801 and a limiting sleeve 803. The outer surface of the vertical displacement column 801 is provided with a first moving groove 802 and a second moving groove 804. The second moving groove 804 is adapted to the horizontal displacement component 9. The first limiting sleeve 803 passes through the horizontal displacement component 9 and the first moving groove 802 and extends to its outer surface. The advantage is that, through the design of the vertical displacement component 8, the position can be flexibly adjusted in the vertical direction to meet the positioning requirements of different paper sizes. The first moving groove 802 and the first limiting sleeve 803 ensure the stability of the connection between the horizontal displacement component 9 and the vertical displacement column 801, while the second moving groove 804 allows the horizontal displacement component 9 to be finely adjusted, improving the positioning accuracy.

[0032] Specifically, the horizontal displacement component 9 includes a horizontal displacement column 901 and a limiting sleeve 905. The outer surface of the horizontal displacement column 901 is provided with a moving groove 902 and a moving groove 903. A fixing block 904 is fixedly installed on the inner surface of the horizontal displacement column 901. The fixing block 904 is adapted to the vertical displacement component 8. The advantage is that the horizontal displacement component 9 realizes the adjustment function of the positioning structure in the horizontal direction. Combined with the vertical displacement component 8, the position of the positioning structure can be flexibly adjusted in a two-dimensional plane. The fixing block 904 ensures the connection stability between the horizontal displacement column 901 and the vertical displacement column 801. The moving groove 902, the limiting sleeve 905, and the moving groove 903 provide convenience for the installation and movement of the positioning component 10, further improving the flexibility and accuracy of positioning.

[0033] Specifically, the second limiting sleeve 905 passes through the third moving groove 902 and the positioning component 10 and extends to its outer surface. The fourth moving groove 903 is slidably connected to the positioning component 10. The advantage is that the cooperation between the second limiting sleeve 905 and the third and fourth moving grooves 902 and 903 allows the positioning component 10 to flexibly adjust its position and be fixed on the horizontal displacement column 901, which facilitates precise positioning adjustment according to the actual situation of the paper and ensures the accuracy of positioning.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the positioning component 10 includes a positioning strip 1001, with an insert strip 1002 fixedly installed on its outer surface. A fixing bolt 1003 and a contact piece 1004 are provided through the other end of the positioning strip 1001 away from the insert strip 1002. The advantages are that the design of the positioning component 10 can position the paper, the insert strip 1002 facilitates the installation and removal of the positioning strip 1001 and the horizontal displacement column 901, the fixing bolt 1003 can ensure that the position of the positioning strip 1001 is fixed, and the contact piece 1004 can better realize the positioning function when in contact with the paper, thus improving the stability and accuracy of paper positioning.

Mounting bolts 1103 are provided at the four corners of the first limiting frame 1101 and the second limiting frame 1102. The mounting bolts 1103 pass through the first limiting frame 1101 and the second limiting frame 1102 and extend to their outer surfaces. The advantage is that the limiting component 11 can limit the mounting bracket 2 and other components, preventing them from sliding or shaking excessively on the fixed bracket 1, thus ensuring the stability of the entire positioning structure. The fixing method of the mounting bolts 1103 makes the installation and disassembly of the first limiting frame 1101 and the second limiting frame 1102 convenient and easy to adjust according to the actual situation.

[0037] Specifically, the outer surface of the second limiting frame 1102 is provided with a slot 1104, and a locking post 1105 and a sliding frame 1106 are fixedly installed on the inner surface of the slot 1104. A sliding roller 1107 is rotatably installed on the inner surface of the sliding frame 1106. The advantage is that the locking post 1105 can position and limit the component to a certain extent, and the combination of the sliding frame 1106 and the sliding roller 1107 reduces the friction when the component slides. When in contact with paper, it can reduce its friction and improve the smoothness during printing. At the same time, it also reduces the wear of the component and the second limiting frame 1102, and extends the service life of the equipment.

[0038] Working principle: During use, the mounting frame 2 can slide on the fixed frame 1, providing a basis for adjusting the position of the entire positioning structure. The vertical displacement column 801 of the vertical displacement component 8 slides in the slide groove 7 of the mounting frame 2, realizing vertical position adjustment. The horizontal displacement component 9 is adapted to the moving groove 804 of the vertical displacement column 801 through the fixing block 904, and can move with the vertical displacement column 801 and can be adjusted in the horizontal direction itself. The positioning component 10 is installed in the moving groove 903 of the horizontal displacement column 901 through the insert 1002 and is fixed in position by the limiting sleeve 905, thereby realizing flexible adjustment of the paper positioning position in a two-dimensional plane. The mounting plate 3 is fixed to one end of the mounting frame 2, and the reinforcing rib 6 strengthens the connection. For strength, spring 4 connects mounting plate 3 and top block 5. Top block 5 is connected to vertical displacement component 8. During adjustment, spring 4 can provide a certain buffer and auxiliary positioning function. Limiting component 11 is composed of limiting frame one 1101 and limiting frame two 1102 connected by mounting bolt 1103. It limits the mounting frame 2 and other components. The locking post 1105 in the slot 1104 on limiting frame two 1102 and the sliding roller 1107 in the sliding frame 1106 play the role of positioning, limiting and reducing friction when the components slide. The positioning strip 1001 of positioning component 10 is fixed in a suitable position by fixing bolt 1003. The contact piece 1004 contacts the paper to realize the positioning of the paper to meet the paper positioning requirements of the printing press.
