Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum foil processing technology, and in particular to a grinding and polishing device for preparing aluminum foil cross sections. Background Technology
[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Its stamping effect is similar to that of pure silver foil, hence it is also called imitation silver foil. Because aluminum is soft, ductile, and has a silvery-white luster, if the rolled sheets are mounted on offset paper with substances such as sodium silicate to form aluminum foil sheets, they can be printed on. Due to its excellent properties, it is widely used in food, beverages, cigarettes, pharmaceuticals, photographic negatives, and household goods, typically as packaging material; electrolytic capacitor material; insulation material for buildings, vehicles, ships, and houses; and also as decorative gold and silver threads, wallpaper, and decorative trademarks for various stationery and light industrial products. To improve the quality of aluminum foil after production, the cross-section of the aluminum foil needs to be polished.
[0003] A search revealed a polishing device for preparing aluminum foil cross-sections (publication number: CN221621669U) on the Chinese Patent Network. The device involves placing abrasive paper on a flat table, placing two bases on the water-wetted abrasive paper, and placing a clamping disc on the base's track. The aluminum foil is placed upright between the first and third clamps, with the bottom of the foil touching the abrasive paper. Tightening the cap screw causes the cap screw to push the third clamp to hold the aluminum foil. The clamping disc is then moved along the track to polish the bottom cross-section of the aluminum foil until it is smooth and shiny. This device has a simple structure and low production cost, but it can quickly and effectively polish the aluminum foil cross-section, making it convenient to use and widely applicable. However, this patent still has certain shortcomings in practical use, such as:
[0004] The clamping disc in this patent clamps the aluminum foil and then moves it along the track to polish it. However, there is a large distance between the clamping disc and the sandpaper, and the aluminum foil is a flexible material. During the friction process between the aluminum foil and the sandpaper, the aluminum foil is easily bent between the clamping disc and the sandpaper due to excessive friction. This causes the side of the aluminum foil to also come into contact with the sandpaper, and the cross-section cannot be perpendicular to the sandpaper, resulting in poor polishing effect on the cross-section of the aluminum foil. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding and polishing device for preparing aluminum foil cross sections.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Preferably, both the first clamping plate and the second clamping plate have threaded holes on their sides, and the first clamping plate and the second clamping plate are threadedly connected to the first screw and the second screw through the threaded holes, respectively.
[0009] Preferably, the ends of the two lead screws away from the inner wall of the movable groove extend to the opposite sides of the first clamping plate and the second clamping plate, respectively, and the two connecting brackets are threadedly connected to the two lead screws, and the positions of the two outward locking plates and the inward locking plates correspond to each other.
[0010] Preferably, the clamping assembly includes a movable block, a pull rod is fixedly connected to the upper surface of the movable block, and a pressure plate is fixedly connected to the lower surface of the movable block.

The bottom limit position of the aluminum foil is locked by the inward and outward locking plates, ensuring that the aluminum foil will not bend significantly when it rubs against the surface of the polishing paper, thereby improving the polishing effect on the aluminum foil section. In addition, the position of the polishing paper can be locked by the clamping assembly, ensuring that the polishing paper will not shift due to excessive friction, thus affecting the polishing effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example:
[0022] Reference Figure 1-4A polishing device for preparing aluminum foil cross-sections includes a processing table 1. A polishing groove is formed on the upper surface of the processing table 1, and polishing sandpaper 2 overlaps the inner bottom wall of the polishing groove. Two polishing components are fixedly connected to the upper surface of the processing table 1. Two positioning grooves are formed on the upper surface of the processing table 1 at positions corresponding to the polishing groove. A clamping component is slidably connected to the inner wall of each positioning groove. Each polishing component includes a first strip frame 3 and a second strip frame 4. Strip-shaped through holes are formed on the front sides of both the first strip frame 3 and the second strip frame 4. The inner walls of the two strip-shaped through holes slide... The positioning plate 5 is connected to a first clamping plate 6 and a second clamping plate 7. The left and right sides of the positioning plate 5 are rotatably connected to a first screw 8 and a second screw 9. The front of the positioning plate 5 is fixedly connected to a push rod 10. The lower surface of the positioning plate 5 is fixedly connected to two inward locking plates 11. The lower surfaces of the first clamping plate 6 and the second clamping plate 7 are both provided with movable grooves. The inner top wall of the movable groove is slidably connected to a connecting frame 12. The opposite faces of the two connecting frames 12 are fixedly connected to an outward locking plate 13. The inner walls of the two movable grooves are rotatably connected to a lead screw 14.
[0023] The first clamping plate 6 and the second clamping plate 7 are both provided with threaded holes on their sides. The first clamping plate 6 and the second clamping plate 7 are respectively threaded to the first screw 8 and the second screw 9 through the threaded holes. The ends of the two lead screws 14 away from the inner wall of the movable groove extend to the opposite sides of the first clamping plate 6 and the second clamping plate 7, respectively. The two connecting brackets 12 are respectively threaded to the two lead screws 14. The positions of the two outward locking plates 13 and the inward locking plates 11 are corresponding.
[0024] After rotating the first screw 8 and the second screw 9, the first clamping plate 6 and the second clamping plate 7 can be driven to move closer to the positioning plate 5. At this time, the gap between the first clamping plate 6 and the second clamping plate 7 and the positioning plate 5 can clamp the two sets of aluminum foil or the two sections of the same aluminum foil at the same time, and make the aluminum foil section contact the surface of the bottom polishing sandpaper 2. After rotating the two lead screws 14, the two connecting frames 12 can drive the two outward locking plates 13 to move closer to the inward locking plate 11, which can press the bottom position of the aluminum foil to the maximum extent, ensuring that the aluminum foil will not undergo large deformation when the positioning plate 5 is moved left and right by the push rod 10, thereby improving the polishing effect of the aluminum foil section.
[0025] The clamping assembly includes a movable block 15. A pull rod 16 is fixedly connected to the upper surface of the movable block 15, and a pressure plate 17 is fixedly connected to the lower surface of the movable block 15. The pressure plate 17 extends into the interior of the polishing groove and overlaps with the upper surface of the polishing sandpaper 2. The front and rear inner walls of the positioning groove are provided with moving grooves. A locking rod 18 is fixedly connected to the inner bottom wall of the moving groove. A spring 19 is sleeved on the surface of the locking rod 18. A transmission plate 20 is slidably connected to the inner walls of the two moving grooves. The opposite surfaces of the two transmission plates 20 are fixedly connected to the front and back of the movable block 15, respectively. The transmission plate 20 is slidably connected to the surface of the locking rod 18, and the top end of the spring 19 overlaps with the inner top wall of the moving groove, and the bottom end of the spring 19 overlaps with the upper surface of the transmission plate 20.
[0026] When the polishing sandpaper 2 loses its polishing effect and needs to be replaced, firstly, the two pull rods 16 drive the two movable blocks 15 to move upward. The two movable blocks 15 can squeeze the springs 19 on the surface of the two locking rods 18 through the two transmission plates 20, and at the same time drive the pressure plate 17 to disengage from the surface of the polishing sandpaper 2, so that the polishing sandpaper 2 is no longer restricted in the polishing groove. At this time, after replacing the polishing sandpaper 2, it is placed back into the polishing groove. Release the two pull rods 16, and the reaction force generated by the springs 19 can drive the pressure plate 17 to press the polishing sandpaper 2 tightly in the polishing groove, ensuring that the position of the polishing sandpaper 2 will not move, thereby improving the polishing effect on the aluminum foil.
[0027] Working principle: First, insert both ends of the aluminum foil into the gaps between the first clamping plate 6, the second clamping plate 7, and the positioning plate 5, respectively. Simultaneously rotate the first screw 8 and the second screw 9 to bring the first clamping plate 6 and the second clamping plate 7 closer together until they clamp the aluminum foil in the two gaps. At the same time, rotate the two lead screws 14 to bring the two connecting frames 12 closer together. At this time, the two connecting frames 12 can drive the two outward locking plates 13 to move closer to the two inward locking plates 11 until the two sets of inward and outward locking plates can clamp the bottom of the aluminum foil. Then, the push rod 10 drives the positioning plate 5 to move left and right so that the two ends of the aluminum foil can be aligned with the polishing sandpaper 2. Surface friction is used to polish the aluminum foil cross section. The two sets of inward and outward locking plates can minimize the deformation distance between the aluminum foil and the sandpaper, so that the aluminum foil will not tilt when rubbing against the sandpaper 2, thereby improving the polishing effect of the aluminum foil cross section. In addition, after the two pull rods 16 pull the movable block 15 upward, the two transmission plates 20 can be driven to squeeze the spring 19 on the surface of the locking rod 18, thereby driving the pressure plate 17 away from the sandpaper 2, which facilitates the replacement of the sandpaper 2. During the use of the sandpaper 2, the force of the spring 19 can drive the pressure plate 17 to press the sandpaper 2 tightly, ensuring the stability of the sandpaper 2.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
