Description

Technical Field

[0001] The utility model belongs to the technical field of lathes, and in particular relates to a rubber roller auxiliary grinding device. Background Art

[0002] During the processing of metal packaging flat plates (including tinplate, chrome-plated iron, aluminum plates, etc.), rubber rollers are required to apply various coatings to improve product quality and achieve special appearance effects. The surface quality of the rubber roller is crucial to the leveling effect of the paint film and the control of the film weight difference with the plate. In order to improve the surface quality of the rubber roller, it is often necessary to grind the rubber roller on a lathe. Most of the lathes on the market currently only grind the rubber roller with a single grinding wheel. The surface quality after grinding still cannot meet practical needs. In some cases, it is necessary to manually put sandpaper against the rubber roller to further grind the rubber roller with sandpaper. However, during manual operation, due to the high speed of the lathe, it is easy to bring certain dangers. Summary of the invention

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] A rubber roller auxiliary grinding device is installed on a lathe 1 and is used to cooperate with the lathe 1 to grind the rubber roller. The auxiliary grinding device includes a base 2, a sandpaper fixing assembly 3 and sandpaper 4. The base 2 is adjustably mounted on a tool holder 5 of the lathe 1, so that the auxiliary grinding device can be driven to move by the tool holder 5, thereby grinding the surface of the rubber roller. The sandpaper 4 is installed on the base 2 through the sandpaper fixing assembly 3. The sandpaper fixing assembly 3 is provided with an abutting surface 3-1. The sandpaper 4 is abutted against the rubber roller through the abutting surface 3-1, so that the sandpaper 4 can grind the rubber roller 8 and improve the surface quality of the rubber roller 8.

[0021] A tool holder 5 is slidably mounted on the lathe 1, a grinding frame 6 is mounted on the tool holder 5, an auxiliary grinding device and a grinding wheel assembly 7 are mounted on the grinding frame 6, the rubber roller is preliminarily ground by the grinding wheel assembly 7, and then the rubber roller is further ground by the auxiliary grinding device, thereby improving the surface quality of the rubber roller.

[0022] The grinding wheel assembly 7 includes a motor 7-1 and a grinding wheel 7-2. The motor 7-1 is connected to the grinding wheel 7-2 via a belt and a pulley. The motor 7-1 drives the grinding wheel 7-2 to rotate, thereby facilitating the grinding wheel 7-2 to grind the rubber roller.

[0023] The sandpaper fixing assembly 3 includes a movable seat 3-5 and a sandpaper fixing plate 3-6. The movable seat 3-5 is L-shaped. The movable seat 3-5 is installed on the base 2 by bolts. The sandpaper fixing plate 3-6 is installed on the movable seat 3-5 by bolts. The sandpaper 4 is detachably installed on the sandpaper 4 fixing plate by bolts, which is convenient for replacing the sandpaper 4.

[0024] Abutment block 3-2 is provided on the side of the sandpaper fixing plate 3-6 facing the rubber roller, and abutment surface 3-1 is formed on the abutment block 3-2. The sandpaper 4 is abutted against the surface of the rubber roller through the abutment block 3-2 to ensure that the sandpaper 4 can abut against the rubber roller, thereby facilitating the sandpaper to grind the rubber roller. Preferably, the abutment surface 3-1 is in an arc shape, thereby increasing the contact area between the sandpaper 4 and the rubber roller, thereby improving the grinding efficiency of the sandpaper on the rubber roller.

[0025] The end of the sandpaper fixing plate 3-6 is fixed to the middle of the movable seat 3-5, and the sandpaper fixing plate 3-6 is inclined relative to the movable seat 3-5, so that a sandpaper slot 3-3 is formed between the movable seat 3-5 and the sandpaper fixing plate 3-6, and the turned-up sandpaper 4 is clamped through the sandpaper slot 3-3. A plurality of sandpapers 4 are stacked on the sandpaper fixing plate 3-6, each of which has a different mesh number, and the sandpapers 4 are arranged in sequence according to the increasing mesh number of the sandpaper, that is, the sandpaper 4 with a higher mesh number is closer to the sandpaper fixing plate 3-6. During the grinding process, the rubber roller is first grinded with sandpaper with a lower mesh number, and then the sandpaper with a lower mesh number is turned up, so that the end of the sandpaper is inserted into the sandpaper slot 3-3, thereby facilitating the further grinding of the rubber roller with sandpaper with a higher mesh number.

[0026] A rubber pad 3-4 is provided on the movable seat 3-5, and the rubber pad 3-4 is arranged in the sandpaper slot 3-3. The rubber pad 3-4 increases the friction between the sandpaper 4 and the sandpaper slot 3-3, so as to facilitate the limited clamping of the turned-up sandpaper 4.

[0027] A first waist-shaped hole 2-1 and a second waist-shaped hole 2-2 are provided on the base 2. The base 2 is installed on the lathe 1 through the first waist-shaped hole 2-1. The relative positions of the base 2 and the tool holder 5 can be adjusted through the first waist-shaped hole 2-1. The sandpaper fixing assembly 3 is installed on the base 2 through the second waist-shaped hole 2-2. The relative positions of the base 2 and the sandpaper fixing assembly 3 can be adjusted through the second waist-shaped hole 2-2; the first waist-shaped hole 2-1 and the second waist-shaped hole 2-2 are arranged along the radial direction of the rubber roller.
