Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding machine protection, and in particular to a sliding door for grinding machine protection. Background Technology
[0002] During grinding, to prevent flying debris and coolant from injuring operators, protective covers are usually installed around the grinding machine, and sliding doors are installed in the operating area. To facilitate observation of the processing, existing sliding doors often have transparent viewing openings, usually made of transparent materials such as tempered glass or acrylic. However, the fine metal debris and dust generated during grinding can easily adhere to the inner wall of the transparent viewing opening. Over time, this accumulation can seriously affect the operator's visibility, reduce work efficiency, and even pose safety hazards.
[0003] Currently, the conventional method for cleaning transparent observation windows is to have operators manually disassemble the observation window or use tools to wipe it inside the protective cover after the machine is shut down. This method is not only time-consuming and labor-intensive, but also has poor cleaning effect, making it difficult to completely remove stubborn stains. It also presents problems such as inconvenience in operation and safety hazards. In addition, debris is also prone to accumulate at the bottom guide rail of the sliding door, affecting the smooth movement of the sliding door and even causing it to jam. Regular cleaning is required, which increases maintenance costs and workload.
[0004] Therefore, it is necessary to propose a sliding door for grinding machine protection to solve the above problems. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-6 As shown, a sliding door for protecting a grinding machine includes a frame 1, a base frame 2 located at the lower end of the frame 1, a top frame 4 located at the upper end of the frame 1, and a sliding door body 3 movably disposed between the base frame 2 and the top frame 4. Both the base frame 2 and the top frame 4 are provided with first guide grooves 6. The upper and lower ends of the sliding door body 3 are provided with grooves 11, extending into the inner side of the grooves 11. Rollers 12 are rotatably disposed within the grooves 11, and the rollers 12 are used for rolling cooperation with the inner wall of the first guide grooves 6. A transparent observation port 5 is provided on the sliding door body 3. Specifically, the back of the sliding door body 3... A recess is provided, and a transparent observation port 5 is provided on the inner wall of the recess. An automatic cleaning component for cleaning the transparent observation port 5 is provided on the back of the sliding door body 3. The automatic cleaning component includes a cleaning plate 10 that is movably provided on the back of the sliding door body 3 and corresponds to the transparent observation port 5. Both sides of the cleaning plate 10 are fixedly provided with drive plates 9 for pushing the cleaning plate 10 to move, and the drive plates 9 correspond to the frame 1. In order to increase the stability of the drive plates 9, guide holes 19 corresponding to the drive plates 9 are provided on the side walls of both ends of the recess on the back of the sliding door body 3. The drive plates 9 are movably guided and connected to the guide holes 19.
[0026] To increase the stability of the sliding door body 3, an arc-shaped second guide groove 13 is provided on the side wall at the lower end of the sliding door body 3. The inner cavity side wall of the first guide groove 6 on the base frame 2 is provided with a guide rail 7 that is adapted to the second guide groove 13. The second guide groove 13 and the guide rail 7 are in a movable guiding cooperation.
[0027] In order to clean the first guide groove 6, a sponge strip 14 is provided on the lower side wall of the sliding door body 3, which is located inside the first guide groove 6. The side of the sponge strip 14 is tightly attached to the inner wall of the first guide groove 6. A through hole 8 is provided at the bottom of the inner cavity of the first guide groove 6 on the base frame 2, and the through hole 8 is located at both ends and the middle of the first guide groove 6.
[0028] To facilitate the disassembly and replacement of the sponge strip 14, a blind hole 18 is provided on the lower side wall of the sliding door body 3. A convex shaft 16 is movably inserted into the blind hole 18. A pressure plate 15 is fixed at the end of the convex shaft 16 away from the blind hole 18. A spring 17 is fixed between the convex shaft 16 and the inner wall of the blind hole 18. The pressure plate 15 is used to press the sponge strip 14 onto the side wall of the sliding door body 3.
[0029] It should be noted that when the sliding door body 3 is closed, the cleaning plate 10 is located at one end of the transparent observation port 5, and the drive plate 9 on one side of the cleaning plate 10 does not protrude from the side wall of the sliding door body 3, while the drive plate 9 on the other side protrudes from the side wall of the sliding door body 3. When the sliding door body 3 is opened, the end of the drive plate 9 protruding from the side wall of the sliding door body 3 will contact the side wall of the frame 1 or the other opposite side wall of the sliding door body 3. As the sliding door body 3 is pushed, the protruding drive plate 9 will push the cleaning plate 10 to move, and the cleaning plate 10 will clean the back of the transparent observation port 5. At this time, due to the displacement of the cleaning plate 10, the drive plate 9 on the other side will protrude from the side wall of the sliding door body 3. When the sliding door body 3 is closed, the drive plate 9 protruding from the other end will also contact the frame 1 or the other opposite side wall of the sliding door body 3, thereby realizing the reset of the cleaning plate 10.
[0030] In addition, when the sliding door body 3 is displaced, the stability can be increased by the second guide groove 13 and the guide rail 7. When the sliding door body 3 moves, it can drive the sponge strip 14 to sweep the inner wall of the first guide groove 6 and scrape out the debris through the through hole 8, which facilitates the rolling of the roller 12.
[0031] When it is necessary to disassemble and replace the sponge strip 14, simply pull the pressure plate 15. The pressure plate 15 stretches the spring 17 through the convex shaft 16, and the pressure plate 15 separates from the sponge strip 14. Then, the sponge strip 14 can be removed and replaced.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
