Description

Technical Field

[0001] The invention belongs to the technical field of kitchen countertop polishing, and in particular relates to an automatic kitchen countertop polishing device. Background Art

[0002] The kitchen countertop is a very important component in the kitchen. Choose a countertop of appropriate size according to the kitchen space and layout to ensure that it is both beautiful and practical after installation. Check the quality of the countertop, including surface flatness, edge treatment, thickness, etc. Good quality countertops have a longer service life.

[0003] Common kitchen countertops are generally made of marble, and marble countertops need to be polished before installation. Manual polishing is troublesome, time-consuming and laborious, and the polishing effect is not good. In addition, a large amount of dust will be generated during the polishing process, which is easy to pollute the environment. At the same time, long-term polishing will cause the polishing block to overheat and be damaged. In view of this, we propose an automatic polishing device for kitchen countertops.

[0055] Working principle: when in use, personnel can first place the kitchen countertop to be polished on a number of rotating rollers 3, and then personnel can start motor 1 8, the output shaft of motor 1 8 will drive the worm 7 to rotate, under the action of meshing, the rotation of the worm 7 will drive a number of worm wheels 6 to rotate, the rotation of a number of worm wheels 6 will respectively drive a number of rotating rollers 3 to rotate, under the action of the friction force of the rubber ring 4, the rotation of a number of rotating rollers 3 can drive the kitchen countertop to move, and then start the hydraulic cylinder 17, the motor 2 16 and the water pump 21, the output shaft of the hydraulic cylinder 17 will drive the polishing block 1 11 and the polishing block 2 12 to move downward through the lower pressure frame 9 until the bottom of the polishing block 11 and the polishing block 2 12 are in contact with the kitchen countertop, and the output shaft of the motor 2 16 will The second transmission wheel 14 is driven to rotate, and the rotation of the second transmission wheel 14 drives the belt 15 to transmit. Under the action of the belt 15, the belt 15 transmission drives the first transmission wheel 13 to rotate. At the same time, the rotation of the first transmission wheel 13 and the second transmission wheel 14 will also drive the grinding block 11 and the second grinding block 12 to rotate respectively. The water pump 21 can extract the water at the bottom of the grinding tank 2 and transport it to the connecting pipe 20. Then the water in the connecting pipe 20 will enter the two water pipes 18 respectively, and finally be sprayed out through a plurality of nozzles 19. The sprayed water will fall on the kitchen countertop, thereby reducing the dust generated during grinding, and preventing the grinding block 11 and the second grinding block 12 from being overheated and damaged. At the same time, the water can also play a lubricating role, so that the polished kitchen countertop has a better effect. The kitchen countertop moves on the plurality of rotating rollers 3, and the grinding block 1 11 and the grinding block 2 12 can automatically grind the kitchen countertop. No human intervention is required during the grinding process, which is convenient and quick. Since the mesh number of the grinding block 1 1 is small, the kitchen countertop can be coarsely ground first. After the coarse grinding is completed, the kitchen countertop can be finely ground due to the small mesh number of the grinding block 2 12, thereby speeding up the grinding efficiency and improving the grinding effect, so that the polished kitchen countertop is smoother. At the same time, the water sprayed by the nozzles 19 can flush the dust generated by grinding into the bottom of the grinding tank 2, and the filter screen 24 can filter the dust in the water. The filtered water will be pumped out by the water pump 21 and used again, thereby saving water resources and not wasting resources. When the filter screen 24 is blocked for a long time, the personnel can press the pressing block 28 downward. The downward movement of the pressing block 28 will drive the limit block 27 to move downward. The downward movement of the limit block 27 will squeeze the spring 29 to contract until the top of the limit block 27 moves out of the plug-in frame 23. At this time, the limit block 27 can release the plug-in frame 23. In addition to limiting the position, personnel can pull out the plug-in frame 23 from the plug-in slot 22 and replace the filter screen 24. After the replacement is completed, the plug-in frame 23 is inserted back into the plug-in slot 22. At this time, under the action of the rebound force of the spring 29, the spring 29 will squeeze the limit block 27 to move upward until the top of the limit block 27 is inserted into the plug-in frame 23. At this time, the limit block 27 can limit the plug-in frame 23. At the same time, under the sealing action of the two sealing gaskets 25, it can be ensured that there will be no water leakage, ensuring that it is convenient for personnel to replace the filter screen 24 and ensuring that the filtering effect of the filter screen 24 can be maintained in the best state.
