Intelligent paper tension stabilizing mechanism of a water-based ink printing machine

Abstract

This utility model discloses an intelligent paper tension stabilizing mechanism for a water-based ink printing machine, belonging to the technical field of water-based ink printing machines. The intelligent paper tension stabilizing mechanism includes a base plate, with mounting shells fixed to both sides of the base plate. A printing machine is fixed to the top of the two mounting shells. A bottom shell is fixed to the top of the two mounting shells. A clamping mechanism for limiting paper of different thicknesses is provided on one side of the bottom shell and inside the two mounting shells. An adjusting mechanism for keeping the paper taut is provided on the other side of the bottom shell and inside the two mounting shells. This utility model, by providing an adjusting mechanism, can change the elastic coefficient of the support spring, automatically adjusting the tension of the adjusting roller through the support spring, thereby keeping the paper taut. Furthermore, since there is only one support spring, uneven force on both ends of the adjusting roller will not affect the stability of the adjusting roller's control over the paper tension.

Description

Technical Field

[0001] This utility model relates to the field of water-based ink printing machine technology, and in particular to an intelligent paper tension stabilization mechanism for water-based ink printing machines. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms such as plate mounting, inking, printing, and paper feeding. Its working principle is to first make a printing plate of the text and images to be printed, mount it on the printing press, and then apply ink to the areas of the printing plate with text and images by hand or by the printing press. The ink is then directly or indirectly transferred to paper or other printing substrates to reproduce printed products identical to the printing plate.

[0003] According to the paper high-efficiency and stable printing machine proposed in announcement number CN218054452U, by setting up two sets of tension adjustment devices, through the cooperation of the same set of support rods and support springs, the same set of support blocks are moved upward, causing the adjustment roller to press against the lower surface of the paper. Through the cooperation of the adjustment roller and the two support rollers in the same set, the paper is made to form a triangular shape, so that the paper is always kept in a tight state during the transport, which helps to prevent the paper from loosening during the transport, improves the printing quality of the paper, promotes stable and efficient paper printing, and improves the practicality of the equipment.

[0004] Existing water-based ink printing presses typically use an adjusting roller in conjunction with two support rollers to maintain the paper's tension. The adjusting roller uses support springs to stabilize the tension. However, the elastic coefficient of the support springs is fixed, making it impossible to adjust the tension in real time according to the paper thickness and operating conditions. Furthermore, the different elastic coefficients of the multiple support springs can affect the stability of the adjusting roller's control over the paper tension.

[0005] Therefore, there is an urgent need to provide an intelligent paper tension stabilization mechanism for water-based ink printing presses to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an intelligent paper tension stabilization mechanism for water-based ink printing machines.

[0007] To solve the above-mentioned technical problems, the present invention provides a technical solution: an intelligent paper tension stabilizing mechanism for a water-based ink printing machine, including a base plate, mounting shells fixed on both sides of the base plate, and a printing machine fixed to the top of the two mounting shells; A bottom shell is fixed to the top of each of the two mounting shells, and a printing platform is fixed between the two mounting shells.

The bottom shell and the interior of the two mounting shells are provided with a clamping mechanism to limit the paper of different thicknesses, and the other side of the bottom shell and the interior of the two mounting shells are provided with an adjustment mechanism to keep the paper taut.

[0008] Through the above technical solution, the guide roller guides the paper smoothly into and out of the printing platform, and the printing press prints on the paper on the printing platform.

[0009] The present invention is further configured such that: the clamping mechanism includes a first cylinder fixed to the bottom end of the base plate, a first lifting frame is fixed to the bottom end of the piston rod of the first cylinder, and the outside of the first lifting frame is slidably connected to the lifting hole of the mounting shell.

[0013] The present invention is further configured such that: one side of each of the two first connecting plates is fixed with a first slider by bolts, a first support roller is rotatably connected between the two first sliders, and a second support roller is provided on one side of the first support roller and rotatably connected to the mounting shell.

[0014] Through the above technical solution, the first connecting plate adjusts the height of the first support roller through the first slider, and the first support roller cooperates with the second support roller to clamp and limit the paper of different thicknesses.

[0015] The present invention is further configured such that: the adjusting mechanism includes an outer shell fixed to the inner bottom wall of the bottom shell, and the inner shell is provided with a second cylinder fixed to the inner bottom wall of the bottom shell.

[0016] Through the above technical solution, the second cylinder drives the piston rod to move up and down inside the outer casing.

[0017] The present invention is further configured such that: a support spring is fixed to the top of the second cylinder, a second lifting frame is fixed to the top of the support spring, and the exterior of the second lifting frame is slidably connected to the lifting hole of the mounting shell.

[0018] Through the above technical solution, the second cylinder compresses the support spring through the piston rod, thereby changing the elastic coefficient of the support spring, and the second lifting frame adaptively adjusts through the support spring.

[0019] The present invention is further configured such that: two second connecting plates are fixed at the top of the second lifting frame, the interior of the second connecting plates is slidably connected to the exterior of the positioning slide rod, a second slider is fixed on one side of each of the two second connecting plates, and an adjusting roller is rotatably connected between the two second sliders.

[0020] Through the above technical solution, the second lifting frame adjusts the height of the adjusting roller through the second connecting plate and the second slider, so that the tension of the adjusting roller by the support spring is automatically adjusted.

[0021] The beneficial effects of this utility model are as follows: 1. This utility model has an adjustment mechanism that can change the elastic coefficient of the support spring, and automatically adjust the tension of the adjusting roller through the support spring, so that the paper is kept taut. Moreover, there is only one support spring, so the force at both ends of the adjusting roller will not be uneven, which will affect the stability of the tension of the paper by the adjusting roller. 2. This utility model, by providing a clamping mechanism, can simultaneously adjust the lifting and lowering of multiple first support rollers, thereby clamping and limiting paper of different thicknesses, effectively restricting paper deviation, and ensuring stability during the printing process.
