Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass edge and corner polishing, and more specifically, to a tempered glass edge and corner polishing device. Background Art

[0002] In the existing tempered glass edge polishing technology, there are several key issues that affect the operating efficiency and the final polishing quality.

[0003] First of all, the current mainstream method relies on manual use of angle grinders equipped with polishing wheels to process the edges and corners of tempered glass. This method is not only time-consuming and labor-intensive, but also the polishing quality is difficult to guarantee. Due to differences in manual operations, the polishing results may be different each time. This inconsistency may lead to fluctuations in the quality of glass products, especially in mass production. In addition, long-term manual operation will also increase the labor intensity of the operator, which may lead to reduced work efficiency and occupational health problems.

[0004] Secondly, although some mechanized polishing devices have been used for this type of operation, they usually spray coolant onto the surface of the polishing wheel during the polishing process to cool the polishing wheel and help rinse away the waste chips generated during the polishing process. However, existing equipment usually does not allow the coolant delivery speed to be adjusted, which means that the operator cannot adjust the coolant spraying speed and amount according to different polishing requirements. If there is too much or too little coolant, it may have a negative impact on the polishing effect. For example, too much coolant may cause the polishing surface to be too wet, affecting the polishing quality; while insufficient coolant may cause the polishing wheel to overheat, accelerate wear and affect the polishing effect.

[0005] In addition, the installation and removal operations of the polishing wheels in the prior art are usually complicated and time-consuming, which limits the rapid replacement of the polishing wheels. During the production process, the polishing wheels may need to be replaced with wheels of different coarsenesses according to different polishing requirements, or the polishing wheels whose efficiency has been reduced due to wear may be replaced. The complicated replacement procedure not only prolongs the downtime of the equipment, but also increases production costs. Utility Model Content

[0041] A handle 31 is provided at one end of the connecting rod 21 , and the handle 31 is fixedly mounted at one end of the connecting rod 21 .

[0042] More specifically, when the device is needed to polish the edges and corners of a tempered glass building, the tempered glass is first placed on the first conveying roller 17. Due to the special structural design of the first conveying roller 17, the tempered glass is placed at an angle at this time. Then, the external drive assembly is turned on to drive the first conveying roller 17 to convey the tempered glass. At the same time, the motor 2 is turned on. The corresponding motor 2 drives the transmission belt 4 to rotate through the transmission wheel 5 connected to the output end, thereby driving the transmission wheel 5 connected to the top of the polishing wheel 3 to rotate in turn, thereby driving the corresponding polishing wheel 3 to rotate. Since the polishing wheel 3 here is installed at an angle, the polishing wheel 3 here will The corners of the glass are polished, and at the same time, the external conveying equipment is turned on. The coolant is conveyed to the spraying assembly 6 through the input pipe 16 by the external conveying equipment, and then the coolant is sprayed onto the polishing wheel 3 and the surface of the tempered glass through the spraying assembly 6. Then the sprayed coolant will carry the waste into the collection bin 19 arranged below, and then the tempered glass with the polished corners will be further conveyed to the second conveying roller 18. Then the tempered glass on the second conveying roller 18 will be restored to a horizontal position, and then the corresponding motor 2 is turned on, and the motor 2 drives the corresponding polishing wheel 3 to rotate, so as to polish the side wall of the tempered glass. When the corresponding polishing wheel 3 needs to be When replacing, the matching sleeve 23 is fixed by the connecting plate 20 so that the matching sleeve 23 does not rotate, and then the connecting rod 21 is rotated by the handle 31. The first spring 30 arranged on the inner side of the connecting rod 21 will be squeezed due to the arrangement of the return block 29. At the same time, the connecting rod 21 will drive the reducing groove 25 arranged on the side wall to rotate. Due to the special structural design of the reducing groove 25 and the limiting of the matching block 24 by the limiting groove 26 opened on the side wall of the matching sleeve 23, the matching block 24 will not rotate with the connecting rod 21. Then the second spring 28 will be reset during the rotation of the reducing groove 25 and make one side of the matching block 24 always aligned with the reducing groove 29. 5 side walls are tightly attached, so that the matching block 24 gradually disengages from the matching groove 27. When the first spring 30 is compressed to the limit, the connecting rod 21 cannot continue to rotate, and at the same time, one end of the matching block 24 completely disengages from the matching groove 27. Then, the connecting rod 21 is pulled in the corresponding direction by the handle 31. Due to the design of the limiting groove 26, the matching block 24 will drive the matching sleeve 23 to move outward, and then the matching sleeve 23 will be pulled out of the matching sleeve 23 together with the connecting rod 21, so that the two connecting plates 20 no longer clamp the polishing wheel 3. When the polishing wheel 3 is replaced, the new polishing wheel 3 can be reinstalled back to the original position according to the above process.

[0043] In summary, when the overall equipment is in use or running: when it is necessary to adjust the delivery flow rate of the coolant, the threaded sleeve 12 is rotated in the corresponding direction, and the threaded sleeve 12 drives the screw 14 connected inside to rotate. Since the screw 14 and the threaded sleeve 9 are movably connected through threads, and due to the mutual limitation of the slide groove 10 and the slider 11, the threaded sleeve 9 and the top sleeve 13 will not rotate, and then the threaded sleeve 9 will drive the top sleeve 13 to slide along the screw rod 14, and at the same time, the top sleeve 13 will drive the slider 11 to slide in the slide groove 10, and then the top of the top sleeve 13 will gradually push open the spoiler 8, and make the spoiler 8 gradually approach the inner wall of the fixed tube 15, and at the same time, the spoiler 8 will squeeze the push spring 7 set on one side. At this time, the cross-sectional area of ​​the corresponding position in the fixed tube 15 changes, thereby changing the delivery flow rate of the coolant. After adjusting appropriately, stop rotating the threaded sleeve 12.

[0044] When the device is needed to polish the corners of the tempered glass building, first place the tempered glass on the first conveyor roller 17. Due to the special structural design of the first conveyor roller 17, the tempered glass is placed at an angle at this time. Then, the external drive assembly is turned on to drive the first conveyor roller 17 to convey the tempered glass. At the same time, the motor 2 is turned on. The corresponding motor 2 drives the transmission belt 4 to rotate through the transmission wheel 5 connected to the output end, thereby driving the transmission wheel 5 connected to the top of the polishing wheel 3 to rotate in turn, thereby driving the corresponding polishing wheel 3 to rotate. Since the polishing wheel 3 here is installed at an angle, the polishing wheel 3 here will polish the corners of the tempered glass. Polishing is carried out, and at the same time, an external conveying device is turned on. The coolant is conveyed to the spraying assembly 6 through the input pipe 16 by the external conveying device, and then the coolant is sprayed onto the polishing wheel 3 and the surface of the tempered glass through the spraying assembly 6. Then the sprayed coolant will carry the waste into the collection bin 19 arranged below, and then the tempered glass with the polished corners will be further conveyed to the second conveying roller 18, and then the tempered glass reaching the second conveying roller 18 will be restored to a horizontal position, and then the corresponding motor 2 is turned on, and the motor 2 drives the corresponding polishing wheel 3 to rotate, so as to polish the side wall of the tempered glass. When the corresponding polishing wheel 3 needs to be replaced When changing, the matching sleeve 23 is fixed by the connecting plate 20 so that the matching sleeve 23 will not rotate, and then the connecting rod 21 is rotated by the handle 31, and the first spring 30 arranged on the inner side of the connecting rod 21 will be squeezed due to the setting of the return block 29, and at the same time, the connecting rod 21 will drive the reducing groove 25 arranged on the side wall to rotate. Due to the special structural design of the reducing groove 25 and the limiting groove 26 opened on the side wall of the matching sleeve 23 to the matching block 24, the matching block 24 will not rotate with the connecting rod 21, and then the second spring 28 will be reset during the rotation of the reducing groove 25 and make one side of the matching block 24 always aligned with the side of the reducing groove 25 The wall is tightly attached, so that the matching block 24 gradually disengages from the matching groove 27. When the first spring 30 is compressed to the limit, the connecting rod 21 cannot continue to rotate. At the same time, one end of the matching block 24 is completely disengaged from the matching groove 27. Then, the connecting rod 21 is pulled in the corresponding direction through the handle 31. Due to the design of the limit groove 26, the matching block 24 will drive the matching sleeve 23 to move outward, and then the matching sleeve 23 will be pulled out of the matching sleeve 23 together with the connecting rod 21, so that the two connecting plates 20 no longer clamp the polishing wheel 3. When the polishing wheel 3 is replaced, the new polishing wheel 3 can be reinstalled back to its original position according to the above process.
