[0002] Super clean and bright is an important part of the porcelain tile deep processing and polishing production line. After the product is polished, it will go through the super clean and bright process, which can not only greatly improve the surface gloss of the product, but also greatly improve the surface anti-fouling performance. It is an important means to improve product quality. The tiles treated by the super clean process have the advantages of high gloss, anti-fouling and wear resistance, antibacterial and environmentally friendly. In the super clean grinding head, in order to meet the needs of the production of products of different widths, when producing small specifications, it is necessary to reduce the processing range of the grinding head, and when producing large specifications, it is necessary to increase the processing range. The most traditional and direct method is to replace grinding wheels of different sizes so that tiles can be processed in different ranges. The operation process of replacing grinding wheels is cumbersome, time-consuming and labor-intensive, and more grinding wheels of different specifications need to be prepared in the production process, resulting in increased production costs.

However, in the process of processing a large-sized plate at the same time, the surface of the tile is not polished evenly, resulting in a decrease in processing quality, and it is difficult to position the grinding wheel in the process of adjusting the position of the grinding head.

The guide rail 21 is provided with a plurality of sinks 34 for the abutment member 33 to be inserted into, and the plurality of sinks 34 are arranged along the sliding direction of the slide plate 14 on the mounting plate 13, and each sink 34 corresponds to a center distance between a grinding wheel 16 and a transmission shaft 12. When the abutment member 33 is inserted into the sink 34, the center distance between the grinding wheel 16 and the transmission shaft 12 can be determined according to the corresponding sink 34.

[0043] refer to Figure 5 The locking manipulator includes a gun head 51 and a gun rod 52. The gun rod 52 is fixedly connected to the gun head 51. The gun head 51 is clamped with a bolt and drives the bolt to rotate. The gun head 51 is rotatably connected to a sleeve 55 clamped with the bolt. The sleeve 55 is sleeved on the bolt and circumferentially clamped with the bolt. Compressed gas is input into the gun head 51, and the gun head 51 drives the sleeve 55 to drive the bolt to rotate, thereby realizing the function of the gun head 51 driving the bolt to rotate.

[0044] refer to Figure 6 and Figure 7 The wheel changing device includes a tray 61 and a hand lever 62, the tray 61 is fixedly connected to the hand lever 62, the tray 61 is clamped with the grinding wheel 16, the grinding wheel 16 is provided with a mounting seat 17, the mounting seat 17 is detachably connected to the output shaft of the driving member 15, the output shaft of the driving member 15 is connected to the grinding wheel 16 through the mounting seat 17, and the tray 61 is fixedly connected with a clamping plate 63 clamped with the mounting seat 17. The tray 61 is provided with a plurality of weight-reducing holes 64, the weight-reducing holes 64 are fan-shaped as a whole, and the plurality of weight-reducing holes 64 are evenly distributed around the circumference.

[0045] Specific working process:

[0046] refer to Figure 8 In the working state, the locking member 24 tightens the slide plate 14, and the abutment member 33 is inserted into the sink 34 to realize the positioning of the slide plate 14 and the grinding wheel 16. The transmission shaft 12 is rotated on the support 11, and the transmission shaft 12 drives the mounting plate 13, the driving member 15 and the grinding wheel 16 to rotate, so that the grinding wheel 16 rotates around the transmission shaft 12, so that the grinding wheel 16 can process different positions of the tile, and the position range that the grinding wheel 16 can process is increased. And by the continuous rotation of the grinding wheel 16 around the transmission shaft 12, it is ensured that the grinding wheel 16 can evenly process the surface of the tile, so that the grinding wheel 16 processes the surface of the tile more evenly. Reference Fig. 9When the center distance between the grinding wheel 16 and the transmission shaft 12 needs to be adjusted, the locking member 24 is released from the slide plate 14, the roller 22 contacts the mounting plate 13, and the abutment member 33 is still stuck in the sink 34 under the elastic force of the elastic member 32, but is in a relaxed state. Fig.10 , and then push the slide plate 14 to move, driving the abutment member 33 to slide out of the sink 34 against the resistance. Fig.11 When the slide plate 14 and the grinding wheel 16 move to the appropriate positions, the abutment 33 corresponds to the position of the sink 34, and the elastic member 32 pushes the abutment 33 to get stuck in the sink 34. At this time, the resistance encountered by the slide plate 14 is significantly increased, so that it can sense that the slide plate 14 and the grinding wheel 16 have moved to the appropriate positions, realizing the positioning function, and then tightening the locking member 24 to tighten the slide plate 14, so as to lock the slide plate 14 on the mounting plate 13.

[0047] When it is necessary to process tiles with a smaller width, the slide plate 14 is moved on the mounting plate 13 to drive the grinding wheel 16 to move closer to the transmission shaft 12, so that the center distance between the transmission shaft 12 and the grinding wheel 16 is shortened. When the transmission shaft 12 drives the mounting plate 13, the driving member 15 and the grinding wheel 16 to rotate, the radius of the circular motion of the driving member 15 and the grinding wheel 16 around the transmission shaft 12 is reduced, thereby reducing the processing range of the grinding wheel 16 to adapt to tiles with a smaller width. When it is necessary to process tiles with a larger width, the slide plate 14 is moved on the mounting plate 13 to drive the grinding wheel 16 to move away from the transmission shaft 12, so that the center distance between the transmission shaft 12 and the grinding wheel 16 is increased. When the transmission shaft 12 drives the mounting plate 13, the driving member 15 and the grinding wheel 16 to rotate, the radius of the circular motion of the driving member 15 and the grinding wheel 16 around the transmission shaft 12 is increased, thereby increasing the processing range of the grinding wheel 16 to adapt to tiles with a larger width.

[0048] The positioning mechanism is used to position the slide plate 14, thereby driving the grinding wheel 16 to accurately move to a suitable position. After the position of the grinding wheel 16 is adjusted, the slide plate 14 is locked on the mounting plate 13 by the locking member 24, so that the center distance between the grinding wheel 16 and the transmission shaft 12 remains unchanged, so that the mounting plate 13, the slide plate 14 and the grinding wheel 16 can be driven by the transmission shaft 12 to rotate and process the tiles.

[0049] This embodiment has the following advantages:

[0050] By sliding the slide plate 14 on the mounting plate 13, the driving member 15 and the grinding wheel 16 are driven to move, and the center distance between the grinding wheel 16 and the transmission shaft 12 is adjusted. When the transmission shaft 12 drives the grinding wheel 16 to rotate, the increase in the center distance between the grinding wheel 16 and the transmission shaft 12 will increase the processing range of the grinding wheel 16, and the decrease in the center distance between the grinding wheel 16 and the transmission shaft 12 will reduce the processing range of the grinding wheel 16. When it is necessary to process tiles with larger width specifications, the processing range of the grinding wheel 16 is increased, so that the grinding wheel 16 can meet the processing needs of tiles with larger width specifications, and the grinding wheel 16 can evenly process the surface of the tile. When it is necessary to process tiles with smaller width specifications, the processing range of the grinding wheel 16 is reduced, so that the grinding wheel 16 can meet the processing needs of tiles with smaller width specifications, and the grinding wheel 16 is prevented from detaching from the tile and idling, thereby ensuring processing efficiency. The function of conveniently processing tiles of different specifications is realized.

[0051] By moving the slide plate 14 on the mounting plate 13 to drive the grinding wheel 16 to move, tiles of different widths can be processed without replacing the grinding wheel 16, which facilitates adjustment and saves time and effort. In the process of adjusting the center distance between the grinding wheel 16 and the transmission shaft 12, the slide plate 14 is positioned by the positioning mechanism to position the grinding wheel 16, which facilitates the adjustment of the center distance between the grinding wheel 16 and the transmission shaft 12, thereby achieving the advantage of conveniently positioning the grinding wheel 16.

[0052] The guide rail 21 cooperates with the slide plate 14. When the slide plate 14 moves on the mounting plate 13, the guide rail 21 guides the movement direction of the slide plate 14 to ensure the accuracy of the movement direction of the slide plate 14 and the grinding wheel 16, thereby facilitating the adjustment of the position of the grinding wheel 16.

[0053] By setting the roller 22, the friction between the slide plate 14 and the mounting plate 13 is converted into rolling friction, which effectively reduces the friction between the slide plate 14 and the mounting plate 13, thereby reducing the resistance encountered when adjusting the position of the grinding wheel 16, and facilitating the adjustment of the center distance between the grinding wheel 16 and the transmission shaft 12.

[0054] Tighten the locking piece 24 so that the locking piece 24 pulls the slide plate 14, and the slide plate 14 is pressed against the guide rail 21, and the roller 22 is lifted upward so that the roller 22 cannot contact the mounting plate 13, thereby locking the slide plate 14 on the guide rail 21 and the mounting plate 13, and realizing the function of locking the slide plate 14 on the mounting plate 13 through the locking piece 24.

[0055] The slide plate 14 drives the installation sleeve 31 and the abutment 33 to move during the movement. When the abutment 33 corresponds to the position of the sink 34, the elastic member 32 pushes the abutment 33 to be stuck in the sink 34, increasing the resistance encountered during the movement of the slide plate 14, so that the slide plate 14 can be sensed to have moved to the predetermined position through the resistance. In addition, the elastic member 32 drives the abutment 33 to be stuck in the inner side of the sink 34, which can drive the slide plate 14 to move to a suitable position and can play a self-positioning function to a certain extent. When it is necessary to continue to adjust the position of the slide plate 14 and the grinding wheel 16, the slide plate 14 is pushed against the resistance between the sink 34 and the abutment 33, so that the abutment 33 slides out of the sink 34 until it reaches the next sink 34, thereby realizing the re-positioning of the slide plate 14 and the grinding wheel 16, and realizing the function of the positioning mechanism to position the position of the slide plate 14 and the grinding wheel 16.

[0056] The gun head 51 is a pneumatic bolt gun head 51, and the gun rod 52 is provided with an air pipe 53 and a switch 54. The switch 54 is connected to the air pipe 53 and the gun head 51 respectively. The air pipe 53 is connected to an external air pump, and the switch 54 controls the connection and disconnection of the air pipe 53 and the gun head 51. When the slide plate 14 drives the locking member 24 to move to a position close to the inner side of the mounting plate 13, the gun rod 52 is held by hand and the switch 54 is controlled to connect the air pipe 53 and the gun head 51, and the compressed air in the air pipe 53 drives the gun head 51 to operate, and the locking member 24 is driven to rotate by the gun head 51, so as to realize the function of conveniently tightening or loosening the locking member 24, and avoid the problem that the locking member 24 cannot be twisted due to narrow space when the slide plate 14 and the grinding wheel 16 move to a position close to the inner side of the mounting plate 13.

[0057] When the slide plate 14 drives the locking piece 24 to move to a position close to the inner side of the mounting plate 13, the hand lever 62 is held by hand, and the tray 61 and the clamping plate 63 are driven to move by the hand lever 62, so that the tray 61 supports the lower end of the grinding wheel 16, and the clamping plate 63 is clamped with the mounting plate 13, so that the grinding wheel 16 can be easily removed and replaced, avoiding the problem that the grinding wheel 16 cannot be replaced due to narrow space when the slide plate 14 and the grinding wheel 16 are moved to a position close to the inner side of the mounting plate 13.

[0058] Embodiment 2:

[0059] refer to Figure 2 A grinding head 10 that can adapt to different processing ranges is different from Example 1 in that: the mounting plate 13 is fixedly connected to a slide rail 41, the slide plate 14 is fixedly connected to a slider 42, and the slider 42 is slidably connected to the slide rail 41.

[0060] This embodiment has the following advantages:

[0061] The slider 42 slides on the slide rail 41 , so that the slide plate 14 and the mounting plate 13 move relative to each other, thereby realizing the function of the slide plate 14 moving on the mounting plate 13 .

[0062] Embodiment 3:

[0063] refer to Fig.12 , a grinding head 10 that can adapt to different processing ranges, which is different from the embodiment 1 in that: the mounting plate 13 is provided with a guide groove 43 for the locking member 24 to pass through, the width of the guide groove 43 matches the width of the locking member 24, the locking member 24 is connected with a locking clamping plate 44 that is clamped with the mounting plate 13, and the mounting plate 13 is located between the slide plate 14 and the locking clamping plate 44. The positioning mechanism includes a mounting sleeve 31, an elastic member 32 and an abutment member 33, the elastic member 32 is located in the mounting sleeve 31 and the two ends are respectively connected to the mounting sleeve 31 and the abutment member 33, the mounting plate 13 is provided with a plurality of sinks 34 for the abutment member 33 to be clamped, and the plurality of sinks 34 are arranged along the sliding direction of the slide plate 14 on the mounting plate 13.

[0064] This embodiment has the following advantages:

[0065] The locking member 24 is passed through the guide groove 43 , and the locking member 24 and the slide plate 14 are guided to move through the guide groove 43 , ensuring that the slide plate 14 and the grinding wheel 16 are in the correct movement direction, thereby facilitating the adjustment and positioning of the grinding wheel 16 .

[0066] The slide plate 14 drives the sink 34 to move during the movement. When the abutment 33 corresponds to the position of the sink 34, the elastic member 32 pushes the abutment 33 to be stuck in the sink 34, increasing the resistance encountered by the slide plate 14 during the movement, so that the slide plate 14 can be sensed to have moved to the predetermined position through the resistance. When the position of the slide plate 14 and the grinding wheel 16 needs to be further adjusted, the slide plate 14 is pushed against the resistance between the sink 34 and the abutment 33, so that the abutment 33 slides out of the sink 34 until it reaches the next sink 34, thereby realizing the re-positioning of the slide plate 14 and the grinding wheel 16, and realizing the function of the positioning mechanism to position the slide plate 14 and the grinding wheel 16.
