Description

Technical Field

[0001] This utility model relates to the technical field of metal roller repair, and in particular to a metal roller inner wall repair device. Background Technology

[0002] Metal rollers on the market are prone to accumulating a large amount of dust at their inlet. Over time, this leads to severe particle buildup inside the pipe, affecting the roller's lifespan and causing serious pipe corrosion. Currently, cleaning the inner wall of the roller is generally done by using a cleaning strip with a cloth. However, due to the varying sizes and lengths of the inner walls of different metal rollers, there is a lack of universal cleaning and maintenance devices. Therefore, a metal roller inner wall maintenance device is proposed. The cleaning cotton balls are replaceable and can handle the inner walls of metal rollers of different sizes. The device can also automatically control the cotton balls as they extend into the metal roller, rotating automatically during insertion to clean and maintain the inner wall surface.

[0027] Reference Figures 1-4This is the first embodiment of the present invention, providing a metal roller inner wall repair device. The device includes a telescopic assembly 100 and a repair assembly 200. The telescopic assembly 100 includes a mounting frame 101, a motor 102 mounted on the mounting frame 101, a rotating shaft 103 connected to the motor 102, a gear 104 mounted on the rotating shaft 103, driven wheels 105 symmetrically arranged on both sides of the gear 104, half-gears 106 rotating synchronously with the driven wheels 105, and tooth grooves 107 between the half-gears 106. The repair assembly 200 includes a sliding frame 201 mounted on the mounting frame 101, a sliding rod 202 slidably connected to the sliding frame 201, a screw 203 rotatably connected to the sliding rod 202, a threaded hole 204 on the mounting frame 101, and a cleaning cotton ball 205 at the end of the screw 203.

[0028] The output shaft of the motor 102 is fixedly connected to the rotating shaft 103, which is rotatably mounted on the mounting bracket 101. The gear 104 is fixedly mounted on the rotating shaft 103. The driven wheel 105 meshes with the gear 104 and is rotatably mounted on the mounting bracket 101. Two half-gears 106 are provided, each corresponding to a driven wheel 105, and their rotating shafts are the same. The tooth groove 107 meshes with the two half-gears 106 on both sides. The sliding bracket 201 is positioned above the half-gears 106. The sliding rod 202 is slidably mounted within the sliding bracket 201, and its bottom is fixedly connected to the tooth groove 107. One end of the screw 203 is rotatably connected to the sliding rod 202, and the other end is fixedly connected to the cleaning cotton ball 205. The screw 203 passes through the threaded hole 204, and the screw 203 and the threaded hole 204 are connected by threads.

[0029] During use, position the slide bar 202 towards the metal roller, replace the cleaning cotton ball 205 to fit the inner wall of the metal roller, and start the motor 102. The motor 102 drives the rotating shaft 103 to rotate, and the gear 104 on the rotating shaft 103 begins to rotate. Driven wheels 105 mesh on both sides of the gear 104. The driven wheels 105 can rotate through the rotation of the gear 104. Half gears 106 are also synchronously arranged on the rotating shaft of the driven wheels 105. When the two half gears 106 rotate, since one half gear 106 is engaged with the tooth groove 107, the other half gear 106 is not in contact with the tooth groove 107. Therefore, when one half gear 106 is engaged with the tooth groove 107, the other half gear 106 is not in contact with the tooth groove 107. When the toothed groove 107 is engaged, the half gear 106 drives the toothed groove 107 to move forward. When the other half gear 106 rotates to engage, it pushes the toothed groove 107 back. Thus, the toothed groove 107 moves back and forth in a cycle. Since the toothed groove 107 is fixedly connected to the slide rod 202, the back and forth movement of the toothed groove 107 will drive the slide rod 202 to slide back and forth in a cycle within the sliding frame 201. This can push the screw 203 forward or retract the screw 203 backward. The screw 203 passes through the threaded hole 204. When the thread passes through, the screw 203 will rotate, causing the cleaning cotton ball 205 at the end to rotate and rub against the inner wall of the metal roller, thus improving cleaning and maintenance efficiency.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
