[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example 1:

[0027] like Figures 1-5 As shown, the roller cold coating online repair device of this utility model includes a base 1, a fixing plate 12 installed at the front end of the base 1, a lead screw 131 installed in the middle of the base 1 through a bearing, and track plates 13 arranged on both sides of the base 1; a drive motor 122 is arranged at the front end of the fixing plate 12, and the output shaft of the drive motor 122 is connected to the front end of the lead screw 131; a sliding groove is provided on the track plate 13, and a movable seat 14 is arranged on the track plate 13 through the sliding groove; a repair knife 2 is arranged on the movable seat 14, and a sleeve 142 is arranged at the bottom of the movable seat 14. The sleeve 142 is provided with an internal thread, and the lead screw 131 is threadedly engaged with the sleeve 142.

[0028] In use, the base 1 is first placed on the side of the roller, and the distance between the base 1 and the roller is adjusted so that the repair blade 2 can contact the roller for cold coating. Then, the roller rotates, and the repair blade 2 trims off the excess film on the roller. Afterward, the drive motor 122 is started, which drives the lead screw 131 to rotate. The lead screw 131 moves on the track plate 13 through the sleeve 142, causing the moving seat 14 to move from one end of the roller to the other. This allows the repair blade 2 to trim and repair the excess film on the entire roller without disassembling the roller, saving time and effort, improving repair efficiency, and reducing maintenance costs.

[0029] like Figure 1 , 4 As shown, the lower end of the movable seat 14 is provided with a movable plate 141 that is adapted to the slide groove. The movable plate 141 is set in the slide groove on the track plate 13. The slide groove on the track plate 13 and the movable plate 141 at the lower end of the movable seat 14 cooperate with each other to provide guidance and stable support for the movement of the movable seat 14, ensuring that the movable seat 14 moves smoothly. This allows the repair knife 2 to trim and repair excess film on the entire roller without disassembling the roller, saving time and effort.

[0030] likeFigure 1 , 2 As shown, a cylinder base 121 is mounted on the fixing plate 12, and a drive motor 122 is provided at the front end of the cylinder base 121. The cylinder base 121 facilitates the installation, disassembly, and replacement of the drive motor 122 to adapt to cold-coating repair work of rollers of different specifications and improve repair efficiency.

[0031] like Figure 2 , 3 As shown in Figure 5, the movable base 14 has four sets of threaded holes 143. The repair knife 2 is fixed in the threaded holes 143 by locking bolts 231. A first adjusting plate 21 and a second adjusting plate 22 are installed at the lower end of the repair knife 2, with the first adjusting plate 21 located below the second adjusting plate 22. The locking bolts 231 firmly fix the repair knife 2 to the movable base 14. Simultaneously, the first adjusting plate 21 and the second adjusting plate 22 can adjust the height of the repair knife 2 to adapt to different specifications of roller cold-coating repair work, improving repair efficiency.

[0032] like Figure 2 , 3 As shown, two sets of pressure plates 23 are installed on the upper end of the repair blade 2. Each set of pressure plates 23 has two sets of through holes, and locking bolts 231 are installed in the two sets of through holes on the pressure plates 23. The locking bolts 231 pass through the through holes of the pressure plates 23 and are screwed into the threaded holes 143, firmly fixing the repair blade 2 to the moving base 14. This connection method ensures that the repair blade 2 will not shift or loosen due to vibration, uneven force, or other factors during the repair process, ensuring the accuracy and stability of the repair work, improving repair efficiency, and saving maintenance costs. If it is necessary to make a fine adjustment to the position of the repair blade 2, it can be achieved by loosening or tightening the locking bolts 231. In addition, when the repair blade 2 is worn and needs to be replaced, or when parts such as the pressure plates 23 and locking bolts 231 are damaged, the simple connection method makes it easy to disassemble and replace these parts individually, reducing the maintenance cost and difficulty of the equipment and improving the service life and operational reliability of the equipment.

[0033] like Figure 1 , 2 As shown, a pad 11 is provided at the bottom of the base 1. The height of the base 1 is adjusted by the pad 11 so that the repair knife 2 is in a suitable working position, ensuring that the roller cold coating repair work can be carried out accurately and improving the repair efficiency.

[0034] The utility model discloses a repair knife 2 selects high speed steel material quality, and the output shaft of driving motor 122 is connected through the joint sleeve between the front end of screw rod 131. Repair knife 2 can ensure that in long time, high strength's working process, repair knife 2 always keeps sharp cutting edge, and it is not easy to appear the dull condition of wearing, this makes repair knife 2 can accurately, efficiently complete the finishing, polishing etc. Operation of wearing position, powerfully guarantee the repair quality, ensure that the flatness and the evenness of the repaired cylinder cold rubber coating meet the use requirement, and then prolong the service life of cylinder cold rubber coating, guarantee the stable operation of conveyor roller cylinder.

[0035] The screw thread cooperation of the screw rod 131 and the sleeve 142 can convert the rotary motion of the screw rod 131 into the linear motion of the moving seat 14, when the driving motor 122 drives the screw rod 131 to rotate, due to the accurate transmission of the screw thread, the moving seat 14 can move on the track plate 13 at a stable and accurate speed according to the set trajectory, which makes the repair knife 2 installed on the moving seat 14 can be accurately positioned to any wearing position of the cylinder cold rubber coating, meets different repair requirements, greatly improves the accuracy and efficiency of repair. Embodiment two:

[0036] When the utility model carries out cylinder cold rubber coating on -line repair device work, first, through the height adjustment of adjusting pad 11 to base 1, make the whole device be in the suitable working position, ensure that the repair work can accurately carry out. Then, start driving motor 122, and its output shaft drives screw rod 131 to start rotating through the joint sleeve, due to the screw thread cooperation of screw rod 131 and the internal screw thread on sleeve 142, and sleeve 142 is installed at the lower end of moving seat 14, so the rotary motion of screw rod 131 is converted into the linear motion of moving seat 14 on track plate 13, the sliding slot on track plate 13 and the moving plate 141 on the lower end of moving seat 14 cooperate with each other, provide guidance and stable support for the sliding of moving seat 14, ensure that moving seat 14 moves stably. After that, while moving seat 14 moves, the repair knife 2 installed on it moves, and the repair knife 2 is firmly fixed on the moving seat 14 through two sets of pressing plates 23 and four sets of locking bolts 231, and the repair knife 2 selects high speed steel material quality, and carries out finishing, polishing etc. Repair operation to the cylinder cold rubber coating of wearing or uneven rubber coating by virtue of its high hardness, high wear resistance and good cutting performance, the whole repair process does not need to disassemble the cylinder, and realizes the on -line repair of cylinder cold rubber coating efficiently and conveniently.
