[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 A grinding wheel saw guard device includes a processing table 1, a rotating seat 3 is installed on the processing table 1, a rotating shaft 4 is rotatably provided in the rotating seat 3, the rotating shaft 4 is fixedly connected to a protective cover 5, a drive shaft 6 is rotatably provided in the protective cover 5, a grinding wheel 7 is installed on the drive shaft 6, and a motor 8 connected to the drive shaft 6 is installed on the outer wall of the protective cover 5. A cutting groove 2 is opened on the processing table 1, and further includes:

[0020] The movable mechanism is arranged at one end of the protective cover 5 away from the rotating seat 3, and the movable mechanism is connected to the protective plate 11, which is used to protect the gap between the protective cover 5 and the processing table 1. The movable mechanism is used to provide elastic adjustment function for the protective plate 11.

[0021] During use, the protective cover 5 is lifted and the workpiece to be cut is placed on the processing table 1. Then, the protective cover 5 is pressed down to start the motor 8 and drive the drive shaft 6 to rotate, so that the grinding wheel 7 rotates at high speed to cut the workpiece. In the process of the grinding wheel 7 moving down to cut the workpiece, the protective plate 11 will block the gap between the protective cover 5 and the processing table 1. The protective plate 11 can be elastically adjusted in conjunction with the movable mechanism during the downward rotation of the protective cover 5, so that during the cutting process, flying iron chips can be prevented from bouncing onto the operator from the gap between the protective cover 5 and the processing table 1 and causing burns, thereby improving the safety of cutting.

[0022] In one case of this embodiment, the movable mechanism includes a protective transverse plate 9 installed on the end of the protective cover 5 away from the rotating seat 3, a slide plate 10 is slidingly arranged in the protective transverse plate 9, and the slide plate 10 is fixedly connected to the protective plate 11. A plurality of springs 12 are arranged in the protective transverse plate 9 and are distributed at intervals and connected to the slide plate 10.

[0023] When the protective cover 5 rotates downward around the rotating shaft 4 and the grinding wheel 7 cuts the workpiece placed on the processing table 1, the bottom of the protective plate 11 will contact the processing table 1 and block the gap between the protective cover 5 and the processing table 1. As the protective cover 5 rotates downward, the support of the processing table 1 on the protective plate 11 will cause the protective plate 11 to push the slide plate 10 to slide in the protective cross plate 9, thereby squeezing the spring 12, and the bottom of the protective plate 11 will slide along the surface of the processing table 1 toward the side of the cutting groove 2.

[0024] In one case of this embodiment, a high temperature resistant plate is provided on a side of the protection plate 11 close to the rotating seat 3 .

[0025] The high temperature resistant plate provided on the surface of the protective plate 11 can protect the protective plate 11 and prevent high temperature iron filings from adhering to the protective plate 11 and causing damage.

[0026] In one case of this embodiment, a scraper 17 is installed at the bottom of the protective horizontal plate 9 and is in contact with the heat-insulating plate.

[0027] The scraper 17 can clean the iron filings on the high temperature resistant plate when the protective cover 5 rotates downward.

[0028] In one case of this embodiment, a mounting block 13 is installed at one end of the protective plate 11 away from the skateboard 10, and a movable shaft 14 is rotatably arranged inside the mounting block 13. A roller 15 is arranged on the movable shaft 14, and the roller 15 is in contact with the inner wall of the mounting block 13.

[0029] In order to facilitate the bottom of the protective plate 11 to slide on the surface of the processing table 1, the provided roller 15 can assist the protective plate 11 in moving along the surface of the processing table 1.

[0030] In one aspect of this embodiment, a handle 19 is provided on the protective horizontal plate 9 , and a support base 18 is provided on the processing table 1 .

[0031] The handle 19 can be supported by the support seat 18 , thereby fixing the position of the grinding wheel 7 in the protective cover 5 .

[0032] When the utility model is in use, the protective cover 5 is lifted by the handle 19, and the workpiece to be cut is placed on the processing table 1. Then, the protective cover 5 is pressed downward by the handle 19, and the motor 8 is started to drive the drive shaft 6 to rotate, so that the grinding wheel 7 rotates at a high speed to cut the workpiece. In the process of the grinding wheel 7 moving down to cut the workpiece, the protective plate 11 will block the gap between the protective cover 5 and the processing table 1. The protective plate 11 can be elastically adjusted in the process of the protective cover 5 rotating downward, so that the flying iron chips can be prevented from being thrown from the gap between the protective cover 5 and the processing table 1 during the cutting process. The protective plate 11 is provided with a roller 15 to assist the protective plate 11 in moving along the surface of the processing table 1, so that the position of the protective plate 11 can be adaptively adjusted during the downward rotation of the protective cover 5. The high-temperature resistant plate provided on the surface of the protective plate 11 can protect the protective plate 11 to avoid damage caused by high-temperature iron filings adhering to the protective plate 11, and the scraper 17 can clean the iron filings on the high-temperature resistant plate during the downward rotation of the protective cover 5.
