Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tension adjustment, in particular to a paper conveying tension adjustment roller. Background Art
[0002] Printing is a technology that transfers the ink of text, pictures, photos, anti-counterfeiting manuscripts to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through processes such as plate making, inking and pressurization, so as to batch reproduce the contents of the original manuscripts.
[0003] In the process of printing paper in the related art, a paper feeding mechanism is usually used to feed the paper, and the paper enters the printing press from the paper feed hole of the printing press, and then the printing press is used to print the paper.
[0004] However, since the tension of the paper cannot be controlled during transportation, the tension in some areas is insufficient, causing the paper to be at risk of collapse, which in turn causes the paper to be at risk of wrinkling. Utility Model Content
[0005] The utility model aims to provide a paper conveying tension adjusting roller to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paper conveying tension adjustment roller, comprising a mounting plate, a guide roller assembly is fixedly connected to one side of the mounting plate, an adjustment assembly is arranged between two adjacent guide roller assemblies, the adjustment assembly comprises a guide assembly, a guide path of the guide assembly is perpendicular to the mounting plate, a slider is slidably connected to the guide assembly, an adjustment roller is rotatably connected between two adjacent sliders, and a telescopic assembly is arranged between the slider and the mounting plate.
[0007] Optionally, the number of the guide roller assemblies is at least two groups.
[0008] Optionally, the guide roller assembly includes a mounting seat mounted on a mounting plate, and a guide roller is rotatably connected between two adjacent mounting seats.
[0009] Optionally, the guide assembly includes a connecting seat mounted on the mounting plate, one side of the connecting seat is connected to a guide rod, and the top end of the guide rod is fixedly connected to a limiting plate.
[0010] Optionally, the number of the guide rods is at least two.
[0011] Optionally, the telescopic assembly includes a fixed base mounted on a mounting plate, an electric push rod is rotatably connected to the fixed base, and an extending end of the electric push rod is rotatably connected to a slider.
[0012] Optionally, a distance sensor is fixedly connected to the sliding block.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model enables the paper to pass through the bottom of two groups of guide roller assemblies and then starts the telescopic assembly, which extends and drives the slider to slide. When the slider slides, it pushes the paper, and the paper is tightened by the adjusting roller. When the tension of the paper is too large, the telescopic assembly contracts and drives the slider to slide, which can reduce the thrust of the adjusting roller on the paper, thereby reducing the tension and avoiding the wrinkle problem caused by insufficient tension during the transportation of the paper. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the structure of the utility model;
[0016] Figure 2 It is a structural side view of the utility model. DETAILED DESCRIPTION
[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0018] like Figure 1 to Figure 2 As shown, a paper conveying tension adjustment roller includes a mounting plate 100, a guide roller assembly 200 is fixedly connected to one side of the mounting plate 100, an adjustment assembly 300 is arranged between two adjacent guide rollers 200, the adjustment assembly 300 includes a guide assembly 310, the guide path of the guide assembly 310 is perpendicular to the mounting plate 100, a slider 320 is slidably connected to the guide assembly 310, an adjustment roller 330 is rotatably connected between two adjacent sliders 320, and a telescopic assembly 340 is arranged between the slider 320 and the mounting plate 100.
[0019] By passing the paper through the bottom of the two sets of guide roller assemblies 200 and then starting the telescopic assembly 340, the telescopic assembly 340 extends, driving the slider 320 to slide, and the slider 320 pushes the paper when sliding, and the paper is tightened by the adjusting roller 330. When the paper tension is too large, the telescopic assembly 340 contracts and drives the slider 320 to slide, which can reduce the thrust of the adjusting roller 330 on the paper, thereby reducing the tension. The utility model has a simple structure, uses a small space, and can adjust the paper tension in real time.
