[0022] Please refer to Figures 1 to 4 , Figure 1 The diagram shown is a structural schematic of the grinding belt cleaning device of this utility model with the grinding box installed. Figure 2 The image shown is a cross-sectional schematic diagram of the grinding box of this utility model. Figure 3 The diagram shown is a structural schematic of the grinding belt cleaning device of this utility model without the grinding box installed, from one perspective. Figure 4 The diagram shown is a schematic representation of the abrasive box being installed on the abrasive belt cleaning device from another perspective. Figures 1 to 4As shown, this utility model proposes a grinding belt cleaning device 100 for cleaning grinding belts. The grinding belt is installed in a grinding box 10, which has a main box body 11, a first extension 12, and a second extension 13. The first extension 12 and the second extension 13 extend from the same side of the main box body 11 along a first direction D1, and are spaced apart along a second direction D2. A first turntable 111 and a second turntable 112 opposite to each other along the second direction D2 are provided inside the main box body 11. The first direction D1 and the second direction D2 intersect. A first roller 121 is provided inside the first extension 12, and a second roller 131 is provided inside the second extension 13. The grinding belt is wound around the first roller 111. The grinding belt is connected to the second turntable 112 after passing around the first roller 121 and the second roller 131 on the turntable 111. The grinding belt cleaning device 100 has a recess 21, a drive mechanism 22 and a cleaning mechanism 23. The recess 21 is used to accommodate and fix the grinding box 10. When the grinding box 10 is fixed in the recess 21, the cleaning mechanism 23 is located between the first extension 12 and the second extension 13, and the cleaning mechanism 23 abuts against the grinding belt located between the first extension 12 and the second extension 13. The drive mechanism 22 connects the first turntable 111 and the second turntable 112 to drive the first turntable 111 and the second turntable 112 to rotate, so that the grinding belt is continuously released from the first turntable 111 and cleaned by the cleaning mechanism 23 and then stored on the second turntable 112.

[0023] The present invention relates to a grinding belt cleaning device 100. The grinding belt is installed in the grinding box 10. After the grinding belt is used up, the grinding box 10 together with the grinding belt is directly installed and fixed in the recess 21. A cleaning mechanism 23 is set on the rotation path of the grinding belt, so that the grinding belt to be cleaned on the first turntable 111 is cleaned by the cleaning mechanism 23 and then wound and stored on the second turntable 112. That is, the second turntable 112 has a clean and reusable grinding belt.

[0024] In one embodiment, the recess 21 has a base plate 211, the base plate 211 has a first surface 2111 and a second surface 2112, the first surface 2111 and the second surface 2112 are opposite to each other, when the grinding box 10 is fixed to the recess 21, the first surface 2111 faces the grinding box 10, that is, the first surface 2111 corresponds to the front of the recess 21, and the second surface 2112 corresponds to the back of the recess 21. The cleaning mechanism 23 is located on the first surface 2111 of the base plate 211. The cleaning mechanism 23 has a first cleaning unit 231 and a second cleaning unit 232 arranged opposite to each other along the first direction D1. The first cleaning unit 231 and the second cleaning unit 232 respectively abut against the opposite sides of the grinding belt to clean the opposite two surfaces of the grinding belt simultaneously. Preferably, the second cleaning unit 232, the first roller 121 and the second roller 131 are located on the same horizontal line, that is, the first roller 121, the second cleaning unit 232 and the second roller 131 are arranged sequentially along the second direction D2, so that the grinding belt can move horizontally. There can be a certain gap between the first cleaning unit 231 and the second cleaning unit 232. The gap can be equal to or slightly less than the thickness of the grinding belt, so that the grinding belt is just accommodated between the first cleaning unit 231 and the second cleaning unit 232, ensuring the cleaning effect of the cleaning mechanism 23 on the grinding belt.

[0025] In one embodiment, the drive mechanism 22 is located on the second surface 2112 of the base plate 21. That is, the drive mechanism 22 and the cleaning mechanism 23 are located on opposite sides of the base plate 21. In one embodiment, the drive mechanism 22 is located in the back inner region of the recess 21 and is invisible after installation. The cleaning mechanism 23 is located in the front of the recess 21 and is visible after installation.

[0026] In one embodiment, the drive mechanism 22 has a drive shaft 221, an auxiliary shaft 222, a first driven wheel 223, a second driven wheel 224, a third driven wheel 225, and a fourth driven wheel 226. In the first direction D1, the drive shaft 221, the first driven wheel 223, the auxiliary shaft 222, and the second driven wheel 224 are arranged sequentially. In the second direction D2, the third driven wheel 225 and the fourth driven wheel 226 are located on both sides of the second driven wheel 224, that is, the second driven wheel 224, the third driven wheel 225, and the fourth driven wheel 226 are located on the same horizontal line. 221 is positioned corresponding to the cleaning mechanism 23 and is connected to the first driven wheel 223 via the first belt 24. The auxiliary shaft 222 is connected to the second driven wheel 224 via the second belt 25. The drive shaft 221 is connected to the auxiliary shaft 222 via the third belt 26. The third driven wheel 225 and the fourth driven wheel 226 are respectively positioned corresponding to the first turntable 111 and the second turntable 112. The first driven wheel 223, the third driven wheel 225, the second driven wheel 224 and the fourth driven wheel 226 are connected sequentially via the fourth belt 27 to form a triangle.

[0027] In practical applications, the drive mechanism 22 may include a motor, which drives the drive shaft 221 to rotate counterclockwise. At the same time, the auxiliary shaft 222 rotates counterclockwise synchronously under the drive of the drive shaft 221 and the third belt 26. The first driven wheel 223 connected to the drive shaft 221 and the second driven wheel 224 connected to the auxiliary shaft 222 rotate counterclockwise synchronously under the action of the first belt 24 and the second belt 25, respectively. The third driven wheel 225 and the fourth driven wheel 226 rotate synchronously under the action of the fourth belt 27. The rotation is counterclockwise, meaning that the drive shaft 221, auxiliary shaft 222, first driven wheel 223, second driven wheel 224, third driven wheel 225, and fourth driven wheel 226 in the drive mechanism 22 all rotate counterclockwise in the same direction and at the same speed. Preferably, the drive shaft 221 and auxiliary shaft 222 are the same size, and the first driven wheel 223, second driven wheel 224, third driven wheel 225, and fourth driven wheel 226 have the same diameter, which is more conducive to ensuring the consistency of the rotation direction and rotation speed among the driven wheels. In this embodiment, counterclockwise rotation is used as an example, but in actual operation, it is not limited to this.

[0028] In one embodiment, a first card holder 2113 and a second card holder 2114 are provided on the first surface 2111 of the base plate 211. The main box body 11 may be provided with a corresponding snap-fit ​​structure so that the main box body 11 snaps onto the first card holder 2113 and the second card holder 2114. The first card holder 2113 corresponds to the position of the first turntable 111, and the second card holder 2114 corresponds to the position of the second turntable 112. The base plate 211 has a first hole at the center position corresponding to the first card holder 2113. 2115, the base plate 211 has a second hole 2116 at the center of the second card holder 2114. The rotating shaft of the third driven wheel 225 (not shown in the figure) passes through the first hole 2115 and connects to the first turntable 111. The rotating shaft of the fourth driven wheel 227 (not shown in the figure) passes through the second hole 2116 and connects to the second turntable 112. In this way, the third driven wheel 225 can drive the first turntable 111 to rotate, and the fourth driven wheel 227 can drive the second turntable 112 to rotate.

[0029] like Figure 3 As shown, a positioning pin 2117 is also provided on the first surface 2111 of the base plate 211. The positioning pin 2117 is located between the first retainer 2113 and the second retainer 2114. The positioning pin 2117 is used to assist in positioning the grinding box 10 in the recess 21. The grinding box 10 can be detachably connected to the recess 21 through the first retainer 2113 and the second retainer 2114. In one embodiment, during the process of installing the grinding box 10 into the recess 21, the shell of the grinding box 10 may be provided with a hole 2118 corresponding to the size of the positioning pin 2117. The hole 2118 may be a round hole or a half hole. By inserting the positioning pin 2117 into the corresponding hole 2118 on the grinding box 10, the correct installation position of the grinding box 10 can be ensured, ensuring that the first turntable 111 and the second turntable 112 can rotate under the action of the driven wheel.

[0030] When the grinding box 10 is installed on the grinding machine table, the display panel is ground by the grinding belt. When the grinding belt is completely used, one of the two turntables is empty of grinding belt (for example, only one end of the grinding belt is connected), while the other is wound with the used grinding belt. At this time, the grinding box 10 (along with the grinding belt) can be removed from the grinding machine table and directly installed into the recess 21 of the grinding belt cleaning device 100 to clean the used grinding belt. The grinding belt is continuously released from one turntable and, after being cleaned, is stored and wound onto the other turntable. At this time, the grinding box 10 can be directly reinstalled on the grinding machine table to continue the grinding operation, realizing the reuse of the grinding belt and the convenience of disassembling the grinding box 10.

[0031] In practical applications, the first turntable 111 is connected to the third driven wheel 226 via the rotating shaft of the third driven wheel 225, and the second turntable 112 is connected to the fourth driven wheel 227 via the rotating shaft of the fourth driven wheel 227. Since the third driven wheel 226 and the fourth driven wheel 227 rotate in the same direction and at the same speed, the first turntable 111 and the second turntable 112 rotate in the same direction and at the same speed under the drive of the rotating shaft of the driven wheel. This ensures that the grinding belt will not be damaged due to the inconsistent rotation direction and speed of the first turntable 111 and the second turntable 112 during the process of rotating from the first turntable 111 to the second turntable 112, thus ensuring the smoothness of the grinding belt cleaning process.

[0032] In one embodiment, the first cleaning unit 231 and the second cleaning unit 232 may include free rollers. Further, both the first cleaning unit 231 and the second cleaning unit 232 may be brushes, or both may be anti-static rollers. Alternatively, one of the first cleaning unit 231 and the second cleaning unit 232 may be a brush, and the other may be an anti-static roller. However, in practical applications, this is not a limitation, as long as the cleaning operation of the abrasive belt can be achieved.

[0033] In one embodiment, the grinding belt cleaning device 100 further includes a control panel 30 located beside the recess 21. The control panel 30 is provided with at least one control button. For example, the control panel 30 is provided with a first control button 31, a second control button 32, a third control button 33, and a fourth control button 34. The first control button 31 is used to control the start of the grinding belt cleaning device 100, the second control button 32 is used to control the stop of the grinding belt cleaning device 100, the third control button 33 is used to control the standby of the grinding belt cleaning device 100, and the fourth control button 34 is used to control the emergency stop of the grinding belt cleaning device 100. In practical applications, when the grinding box 10 is installed on the recess 21, the grinding belt cleaning device 100 can be started by pressing the first control button 31. The grinding belt to be cleaned rotates from the first turntable 111 to the second turntable 112 after cleaning. When all the grinding belts have been cleaned, i.e., when there is no grinding belt on the first turntable 111 and all of them are on the second turntable 112, the second control button 32 can be pressed to stop the grinding belt cleaning device 100. If an unexpected situation occurs during the cleaning process, i.e., during the operation of the grinding belt cleaning device 100, such as the grinding belt jamming, the fourth control button 34 can be pressed to stop the grinding belt cleaning device 100 from working immediately. In practical applications, it is not limited to setting four control buttons on the control panel 30; the number of control buttons and their corresponding functions can be set according to actual needs.

[0034] In summary, this utility model provides a grinding belt cleaning device. The grinding belt is installed in the grinding box. After the grinding belt is used up, the grinding box and the grinding belt are directly placed and fixed in the recess. The first turntable and the second turntable are connected by a drive mechanism to drive the first turntable and the second turntable to rotate, so that the grinding belt is recycled after the cleaning mechanism completes the cleaning operation, realizing the reuse of the grinding belt, reducing manufacturing costs, and is easy to operate and improves manufacturing yield.
