A large amount of waste chips and dust will be generated during the polishing process. A filter is generally used to filter the dust and waste chips, but the waste chips on the filter are difficult to clean. After a long period of accumulation, the filter will be blocked, reducing the dust collection efficiency. Utility Model Content

[0004] The utility model aims to provide a grinding machine with a waste chip cleaning mechanism to solve the problem that the filter screen is blocked due to the difficulty in timely cleaning of waste chips after long-term use of the filter screen.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The grinding machine with a waste chip cleaning mechanism, before working, first put the mold on the conveying table and convey it to the inside of the grinding box, at this time, turn on the electric push rod to clamp and fix the clamping plates on both sides to improve the stability of the mold during grinding, and then turn on the grinding device to grind it. The harmful gas generated during the grinding process will be directly absorbed by the vacuum cleaner to avoid inhalation by the staff and endanger their health. The generated waste chips and dust will be filtered by the filter plate through the negative pressure generated by the vacuum cleaner adsorption. Due to long-term accumulation, the waste chips on the filter net are difficult to be cleaned in time, which will block the filter net. At this time, turn on the servo motor to drive the cam to shake the filter plate installed in the filter frame, so that the waste chips and accumulated dust stuck on the filter net are shaken and guided by the guide plate, and fall into the collection box, which can not only clean the filter plate to increase its service life, but also facilitate the effective recovery of the waste chips generated by the dustproof device, and also avoid the waste chips falling to the ground and causing the labor intensity of the operator to increase.

One side of the pair of rotating shafts 10 extends to the outside of the polishing box 3 and is provided with a driving assembly, and the driving assembly includes a sprocket 12 fixedly connected to one side of the pair of rotating shafts 10, and the pair of sprockets 12 are driven by a chain 13. A first fixed plate 14 is fixedly connected to one side of the outside of the polishing box 3, and a servo motor 15 coaxially connected to one of the rotating shafts 10 is fixedly connected to the top of the first fixed plate 14. A second fixed plate 16 is fixedly connected to one side of the outside of the polishing box 3, and a vacuum cleaner 17 is fixedly connected to the top of the second fixed plate 16. Two suction pipes 18 on the outer side of the vacuum cleaner 17 are respectively connected from the polishing The two sides of the box 3 extend to the interior thereof, and a pair of guide plates 19 for collecting waste chips are fixedly connected to the two inner sides of the opening of the polishing box 3, a collection box 20 is slidably connected to the bottom end of the interior of the polishing box 3 and is located below the guide plate 19, a pull ring is fixedly connected to one side of the collection box 20, and a through groove for the sliding of the collection box 20 is provided on one side of the outside of the polishing box 3, a pair of third fixed plates 21 are fixedly connected to the two inner sides of the opening of the polishing box 3, and a blower 22 for blowing waste chips is fixedly connected to the top of the third fixed plate 21. After the mold is processed and formed, its surface needs to be polished to remove burrs on the mold. In the prior art, polishing is generally performed by a grinder, and a large amount of waste chips and dust will be generated during the polishing process. The dust is generally removed through a filter. The waste chips and dust generated during the grinding process are directly absorbed by the vacuum cleaner 17 to avoid inhalation by the staff and endangering their health. The waste chips and dust generated are filtered by the filter plate 9 through the negative pressure generated by the vacuum cleaner 17. Due to the long-term accumulation, the waste chips on the filter net are difficult to be cleaned in time and will block the filter net. At this time, the servo motor 15 is turned on to provide driving power.The transmission between the sprocket 12 and the chain 13 causes a pair of rotating shafts 10 to rotate simultaneously, and the cam 11 located on the outside rotates along with the rotation. Whenever the protruding part of the cam 11 contacts the filter frame 8, the filter frame 8 rotates at a certain angle on the outside of the fixed rod 7. When the cam 11 does not contact, the filter frame 8 will return to its original position due to gravity. The height difference generated back and forth causes the filter plate 9 to shake, so that the waste and accumulated dust stuck on the filter net are shaken and guided by the guide plate 19, and fall into the collection box 20. When the collection box 20 is full, the collection box 20 is pulled out through the pull ring to recycle the waste inside, so that the overall device can not only clean the filter plate 9 and increase its service life, but also facilitate the effective recycling of the waste generated by the dustproof device, and also avoid the waste falling to the ground, which increases the labor intensity of the operator.

[0021] Working principle: before work, the mold is placed on the conveying table 2 and conveyed to the inside of the polishing box 3. At this time, the electric push rod 5 is turned on to clamp and fix the clamping plates 6 on both sides to improve the stability of the mold during polishing. Then the polishing device 4 is turned on to polish it. The harmful gases generated during the polishing process will be directly absorbed by the vacuum cleaner 17 to avoid inhalation by the staff and harm to their health. The waste chips and dust generated will be filtered by the filter plate 9 through the negative pressure generated by the adsorption of the vacuum cleaner 17. Due to long-term accumulation, the waste chips on the filter net are difficult to be cleaned in time and will block the filter net. At this time, the servo motor 15 is turned on to provide driving power, and the transmission between the sprocket 12 and the chain 13 makes a pair of rotating shafts 10 rotate at the same time, and while rotating, they are located on the outside The cam 11 follows the rotation. Whenever the protruding part of the cam 11 contacts the filter frame 8, the filter frame 8 rotates at a certain angle on the outside of the fixed rod 7. When the cam 11 does not contact, the filter frame 8 will return to its original position due to gravity. The height difference generated back and forth causes the filter plate 9 to shake, so that the waste debris and accumulated dust stuck on the filter net are shaken and guided by the guide plate 19, and fall into the collection box 20. When the collection box 20 is full, the collection box 20 is pulled out through the pull ring to recycle the waste debris inside it, so that the overall device can not only clean the filter plate 9 and increase its service life, but also facilitate the effective recovery of the waste debris generated by the dust prevention device, and avoid the waste debris falling to the ground, which increases the labor intensity of the operator.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
