[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Taking the lower side thrust fixing spring shell 4 as an example, the pull block 8 slides into the annular groove of the slide groove 9, the pull block 8 drives the limiting block 5 to move downward, and the limiting block 5 drives the mounting column 7 to move downward. At this time, the thrust spring 6 pushes the limiting block 5 to move upward, and the limiting block 5 drives the pull block 8 to be stuck in the inside of the slide groove 9, thereby facilitating the removal of the rubber roller assembly 3 and the loading and unloading of the flange 2, so as to be applied to the need to adjust the length of the coating rubber roller, adjust the required length of the coating, and conveniently and evenly cover the sizes of various papers, and ensure the quality and uniformity of the coating.

[0031] The connecting rod assembly 1 includes a connecting rod housing 101, the interior of the connecting rod housing 101 is fixedly connected to a connecting fixing ring 102, the left and right ends of the connecting rod housing 101 are slidably connected to a limiting ring 103, one end of the limiting ring 103 close to the connecting fixing ring 102 is fixedly connected to a push spring 104, the end of the limiting ring 103 away from the push spring 104 is fixedly connected to a thrust connecting rod 105, the end of the thrust connecting rod 105 away from the limiting ring 103 is fixedly connected to a mounting rod 106, and the end of the push spring 104 away from the thrust connecting rod 105 is fixedly connected to the connecting fixing ring 101. When the flange 2 is installed at the left and right ends of the fixed ring 102, if the connecting rod assembly 1 protrudes too long, the installation object squeezes the installation rod 106, and the installation rod 106 drives the thrust connecting rod 105 to move relative to each other, and the thrust connecting rod 105 drives the limit ring 103 to move relative to each other, thereby shrinking the connecting rod assembly 1 for easy installation. When the flange 2 is disassembled, the push spring 104 pushes the limit ring 103, thereby completing rapid reset. At the same time, when both sides of the flange 2 are installed, the push spring 104 squeezes the two sides, so that the rubber roller assembly 3 and the connecting rod assembly 1 are more closely fitted to the installation object when they rotate.

[0032] The outside of the connecting rod housing 101 is fixedly connected to the inside of the rubber roller assembly 3, the opposite side of the mounting column 7 is slidably connected to the inside of the mounting rod 106, the end of the thrust spring 6 away from the mounting column 7 is fixedly connected to the inside of the thrust fixing spring shell 4, the outside of the limit block 5 is fixedly connected with a pull block 8, and a slide groove 9 is provided on the outside of the thrust fixing spring shell 4, and the outside of the pull block 8 is slidably connected to the inside of the slide groove 9. Taking the lower side thrust fixing spring shell 4 as an example, the pull block 8 slides into the long groove of the slide groove 9, the pull block 8 drives the limit block 5 to move upward, and the limit block 5 drives the mounting column 7 to move upward. At this time, the thrust spring 6 pushes the mounting column 7 to move upward, and the mounting column 7 slides into the inside of the flange 2, which is convenient for the maintenance of the flange 2 and the adjustment of the number of rubber roller assemblies 3.

[0033] Reference Figure 4 The rubber roller assembly 3 includes a rubber roller shell 301, the interior of the rubber roller shell 301 is slidably connected to the exterior of the connecting rod assembly 1, the interior of the rubber roller shell 301 is fixedly connected to a fixed inner ring 302, the exterior of the fixed inner ring 302 is fixedly provided with an outward push spring 303, one end of the outward push spring 303 away from the fixed inner ring 302 is fixedly connected to an outward push connecting column 304, the exterior of the outward push connecting column 304 is slidably connected to the interior of the rubber roller shell 301, the exterior of the mounting rod 106 is slidably connected to the interior of the fixed inner ring 302, the outward push spring 303 pushes the outward push connecting column 304 to move in the opposite direction of the fixed inner ring 302, so that the rubber roller shell 301 can be quickly reset when subjected to external impact, so that when the rubber roller shell 301 presses other objects, the surface of the rubber roller shell 301 can fit the pressed object better, thereby ensuring the quality and uniformity of the coating, thereby improving the quality of printing.

[0034] Working principle: Taking the lower side thrust fixing spring shell 4 as an example, the pull block 8 slides into the annular groove of the slide slot 9, the pull block 8 drives the limit block 5 to move downward, and the limit block 5 drives the installation column 7 to move downward. At this time, the thrust spring 6 pushes the limit block 5 to move upward, and the limit block 5 drives the pull block 8 to be stuck in the inside of the slide slot 9, so as to facilitate the removal of the rubber roller assembly 3 and the loading and unloading of the flange 2. Taking the lower side thrust fixing spring shell 4 as an example, the pull block 8 slides into the long groove of the slide slot 9, the pull block 8 drives the limit block 5 to move upward, and the limit block 5 drives the installation column 7 to move upward. At this time, the thrust spring 6 pushes the installation column 7 to move upward, and the installation column 7 slides into the inside of the flange 2, which is convenient for the maintenance of the flange 2 and the adjustment of the number of rubber roller assemblies 3. The adjustable steering rubber roller makes the production line or conveying system have higher flexibility. According to needs, it can adapt to objects of different sizes, shapes or weights, thereby meeting different production needs. 303 pushes the outward connecting column 304 to move in the opposite direction of the fixed inner ring 302, so that the rubber roller shell 301 can be quickly reset when it is hit by the outside, so that when the rubber roller shell 301 presses other objects, the surface of the rubber roller shell 301 can fit the pressed object more closely, effectively dispersing the pressure and force of the object during the steering process, reducing the deformation and distortion of the steering rubber roller, and improving its bearing capacity and durability. Then, the steering rubber roller is installed on the bracket, and its position and angle are adjusted as needed, or the steering rubber roller is installed between the printing units of the printing press to adjust and smoothly convey the printing materials, ensure the correct positioning of the printing of different colors or processes, thereby ensuring the printing quality and accuracy, and then adjust its own rotation direction and speed to guide the material to the correct position, avoid problems such as the material deviating from the track or wrinkling, thereby ensuring the production quality and printing quality of the product.
