A fixed guide rail is fixedly installed in the upper part of the body, and a rotating arm is slidably mounted on the fixed guide rail. A sandblasting device is fixedly installed at one end of the rotating arm. This invention utilizes sandblasting and polishing to process the product, and the angle can be adjusted as needed. The structure is simple and practical, increasing production efficiency and reducing costs. However, in practice, the existing technology struggles to balance high efficiency, high precision, and environmental performance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a SIM card tray sandblasting and polishing device, which aims to improve the problem that existing technologies are difficult to balance in terms of high efficiency, high precision and environmental performance during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a SIM card tray sandblasting and polishing device, comprising a body, conveyor belts installed on both the left and right ends of the body, a polishing component installed in the middle of the inner side of the body, a rotating component installed on the front side of the polishing component, a sandblasting component installed on the rear side of the polishing component, a transmission component installed on the rear side of both conveyor belts, a plurality of placement slots equally spaced on the top of the rotating component, and a clamping mechanism installed on the rear top of both conveyor belts for fixing the SIM card tray.

[0006] Through the above technical solution: During operation, the SIM card tray is transported to the transmission component via a conveyor belt, then transported to the top of the rotating component, and then to the bottom of the sandblasting component. The sandblasting head evenly sands the surface of the SIM card tray, and then it enters the grinding component area, where the rotating grinding head finely grinds its surface. Finally, it enters the polishing component area, where the polishing wheel polishes its surface. The entire process is continuously transported by the transmission component and the conveyor belt.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes two motors, which are respectively mounted on the front of the two transmission components. The output end of each motor is fixedly connected to a rotating short column. Connecting ropes are fixedly connected to the left and right ends of the outer side of each rotating short column. Mounting plates are fixedly connected to the bottom front of each of the two transmission components. Clamping plates are slidably connected to the left and right ends of the front of each mounting plate. The tops of the two clamping plates are fixedly connected to the bottoms of the two connecting ropes, respectively. Springs are fixedly connected to adjacent sides of the two clamping plates. Fixing plates are fixedly connected to opposite sides of the two springs. The rear sides of the two fixing plates are fixedly connected to the left and right ends of the front of the mounting plate, respectively.

[0009] The above technical solution involves turning on the motor, rotating the short column to move the connecting rope, and the connecting rope causing the clamping plate to slide. Since the two clamping plates are connected to springs on adjacent sides, the springs buffer and reset during the sliding of the clamping plates, thereby realizing the clamping and releasing operation of the SIM card tray and fixing the SIM card tray.

[0015] The above technical solution facilitates the movement of this device by installing casters.

[0016] As a further description of the above technical solution:

[0017] A mounting base is fixedly connected to the top front left end of the machine body, and a warning light is installed on the top of the mounting base.

[0018] The above technical solution facilitates the inspection and replacement of warning lights through the installation of the mounting bracket.

[0024] The above technical solution facilitates the storage and use of parts through the installation of hooks.

[0025] As a further description of the above technical solution:

[0026] A slot plate is fixedly connected to the middle of the bottom right side of the machine body, and a notice board is installed inside the slot plate.

[0027] The above technical solution facilitates the replacement of notice boards through the installation of the card slot plate.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, during operation, the SIM card tray is conveyed to the transmission component via a conveyor belt, then transported to the top of the rotating component, and then to the bottom of the sandblasting component.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a SIM card tray sandblasting and polishing device, comprising a body 1, conveyor belts 5 installed on both the left and right ends of the body 1, a polishing component 14 installed in the middle of the inner side of the body 1, a rotating component 16 installed on the front side of the polishing component 14, a sandblasting component 20 installed on the rear side of the polishing component 14, and transmission components 17 installed on the rear sides of both conveyor belts 5. The top of the rotating component 16 has multiple placement slots 15 equidistantly spaced, which facilitate the placement of the SIM card tray. The device is placed with clamping mechanisms 2 installed on the top rear side of both conveyor belts 5. The clamping mechanisms 2 are used to fix the SIM card tray. The bottom of the conveyor belts 5 is fixedly connected to a support frame 6. The left side of the body 1 is equipped with an operating device 19. The bottom left and right ends of the support frame 6 and the four corners of the bottom of the body 1 are fixedly connected to support short columns 7. The installation of support short columns 7 makes the device more stable. The bottom of the body 1 is fixedly connected with multiple casters 18 at equal intervals. The installation of casters 18 makes it easy to move the device.

[0040] Specifically, during the operation, the SIM card tray is first conveyed to the transmission component 17 via the conveyor belt 5. The transmission component 17 then transports the SIM card tray to the top of the rotating component 16. After arriving at the rotating component 16, the SIM card tray is then transported to the area below the sandblasting component 20. In this area, the sandblasting head performs uniform sandblasting on the surface of the SIM card tray to ensure a clean and smooth surface. After processing, the SIM card tray enters the polishing component 14 area, where a rotating polishing head performs fine polishing on the surface of the SIM card tray to further remove minor imperfections and unevenness. The polished SIM card tray then enters the polishing component area, where a polishing wheel performs meticulous polishing on the surface of the SIM card tray to achieve a smooth and glossy finish. The entire production process is achieved through the cooperation of the transmission component 17 and the conveyor belt 5, ensuring production efficiency and product quality.

[0041] Reference Figure 1 , Figure 3 and Figure 5The clamping mechanism 2 includes two motors 201, which are respectively installed on the front side of the two transmission components 17. The output end of the motor 201 is fixedly connected to a rotating short column 207. The left and right ends of the rotating short column 207 are fixedly connected to connecting ropes 206. The installation of the motors 201 provides power to the subsequent process. The bottom front side of the two transmission components 17 is fixedly connected to a mounting plate 205. The left and right ends of the front side of the mounting plate 205 are slidably connected to clamping plates 202. The top of the two clamping plates 202 is fixedly connected to the bottom of the two connecting ropes 206. The adjacent side of the two clamping plates 202 is fixedly connected to a spring 203. The opposite side of the two springs 203 is fixedly connected to a fixing plate 204. The rear side of the two fixing plates 204 is fixedly connected to the left and right ends of the front side of the mounting plate 205. The front and rear ends of the right side of the machine body 1 are rotatably connected to cabinet doors 12. The right side of the two cabinet doors 12 is equipped with handles 13. The installation of handles 13 facilitates the opening and closing of the cabinet doors 12.

[0042] Specifically, when the motor 201 is started, its output end will drive the rotating short column 207 to rotate. As the rotating short column 207 rotates, the connecting ropes 206 located on its outer left and right ends will also move accordingly. At the bottom front of the device, two transmission components 17 are fixedly mounted on the mounting plate 205. The front of these mounting plates 205 are connected to the clamping plate 202. The bottom of the connecting rope 206 is fixedly connected to the top of the two clamping plates 202. Therefore, when the connecting rope 206 moves, it will drive the clamping plate 202 to slide along the sliding track. In addition, a spring 203 is connected to an adjacent side of each clamping plate 202, and the side of the spring 203 away from the clamping plate 202 is connected to the fixing plate 204. In this way, the spring 203 can play a buffering role during the sliding of the clamping plate 202 and help the clamping plate 202 to return to its original position after the operation is completed. Through the above process, the clamping and releasing operation of the SIM card tray can be realized, ensuring that the SIM card tray is firmly fixed.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A mounting base 4 is fixedly connected to the top front left end of the body 1. A warning light 3 is installed on the top of the mounting base 4. Slide boxes 10 are fixedly connected to the front and rear ends of the bottom right side of the body 1. Multiple hooks 11 are equally spaced inside the two slide boxes 10. A card slot plate 9 is fixedly connected to the middle of the bottom right side of the body 1. A notice board 8 is installed inside the card slot plate 9.

[0044] Specifically, the installation of warning light 3 serves as a warning and lighting function, the installation of hook 11 facilitates the use and storage of parts, and the installation of slot plate 9 facilitates the replacement of notice board 8.

[0045] Working principle: During operation, the SIM card tray is conveyed to the transmission component 17 via the conveyor belt 5, and then transported to the top of the rotating component 16 via the transmission component 17. From there, it is transported to the sandblasting component 20, where the sandblasting head performs uniform sandblasting on the surface of the SIM card tray. Subsequently, the SIM card tray enters the grinding component 14 area, where the rotating grinding head performs fine grinding on its surface. Finally, the SIM card tray enters the polishing component area, where the polishing wheel polishes its surface. The entire process is continuously conveyed by the transmission component 17 and the conveyor belt 5.

[0046] When the motor 201 is turned on, its output end drives the rotating short column 207 to rotate. The connecting ropes 206 on the left and right sides of the rotating short column 207 will move accordingly. Since the mounting plate 205 is fixed to the bottom front side of the two transmission components 17, and the clamping plate 202 is slidably connected to the left and right sides of the front side of the mounting plate 205, and the top of the two clamping plates 202 is fixedly connected to the bottom of the two connecting ropes 206, the movement of the connecting ropes 206 will drive the clamping plate 202 to slide. Since springs 203 are connected to the adjacent side of the two clamping plates 202, and the side of the springs 203 that is far away is connected to the fixing plate 204, the springs 203 will play a buffering and resetting role during the sliding of the clamping plates 202, thereby realizing the clamping and releasing operation of the SIM card tray and achieving the effect of fixing the SIM card tray.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
