[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Example
[0020] Please see Figure 1-3 This utility model provides a technical solution: a coating grinding and sieving device;
[0021] This invention aims to provide a high-efficiency coating grinding and screening device. Existing coatings require separate screening after grinding, which is cumbersome and reduces coating production efficiency.
[0022] Based on the above issues, the components in this case include a grinding chamber 1, a drive component 2 installed on one side of the grinding chamber 1, a first horizontal shaft 3 installed on the top of the grinding chamber 1 via a bearing seat, the end of the drive component 2 being connected to one side of the first horizontal shaft 3 via a synchronous belt and a synchronous pulley, a first conical tooth 4 installed on the other side of the first horizontal shaft 3, and a rotating shaft 5 rotatably connected to the middle part of the grinding chamber 1 via a bearing, with a second conical tooth 6 installed on the top of the rotating shaft 5;
[0023] Crushing rods 7 are evenly installed on the upper side of the rotating shaft 5, an annular block 8 is installed on the upper side of the grinding chamber 1, and a grinding block 9 matching the annular block 8 is installed at the bottom of the rotating shaft 5. A circular through hole is opened in the middle part of the annular block 8, and the middle part of the bottom of the grinding block 9 is inserted into the circular through hole. A filter assembly is installed on the lower side inside the grinding chamber 1, and a collection tank 10 is slidably connected to the inner wall of the bottom of the grinding chamber 1.
[0024] The filter assembly includes a second horizontal shaft 11. One end of the second horizontal shaft 11 is connected to the inner wall of the grinding chamber 1 via a bearing, and the other end is connected to the driving end of the drive component 2. Cams 12 are installed on both sides of the second horizontal shaft 11. A connecting frame 13 is provided inside the grinding chamber 1. The two sides of the connecting frame 13 are connected to the inner walls of the two sides of the grinding chamber 1 via springs. An opening is provided on the lower side of the connecting frame 13. A filter plate 14 is connected to the upper side of the opening via bolts. The two bottom sides of the connecting frame 13 are connected to two cams 12.
[0025] It should be noted that during the paint production process, a feeding port is provided on one side of the top of the grinding chamber 1. At the same time, the drive unit 2 runs and drives the first horizontal shaft 3 to rotate through the synchronous wheel and synchronous belt. The first conical tooth 4 and the second conical tooth 6 work together to drive the rotating shaft 5 to rotate, and drive the crushing rod 7 to rotate. After the operator puts the paint raw material into the grinding chamber 1, the crushing rod 7 works with the horizontal bar 15 to crush the paint raw material into small pieces, which makes it easier to grind the paint in the future.
[0026] The top of the grinding block 9 is provided with a slope to prevent the crushed paint from adhering to the top of the grinding block 9. Subsequently, the paint is affected by gravity and falls to the bottom of the grinding block 9 and the middle of the arc block. With the operation of the drive unit 2, the paint can be ground. After the grinding is completed, the paint will fall into the interior of the connecting frame 13 due to gravity.
[0027] While the drive unit 2 is running, it will drive the two cams 12 to rotate through the second horizontal shaft 11, and with the help of the spring, it can drive the connecting frame 13 and the filter plate 14 to perform reciprocating vibration operation, so as to screen the ground paint. The screened paint will enter the collection tank 10 for collection. After the grinding and screening operation is completed, the opening and closing door 16 is opened and the paint inside the collection tank 10 is taken out. At the same time, the large particles of paint left on the top of the filter plate 14 can be collected.
[0028] The first guide blocks 17 on both sides of the top of the connecting frame 13 and the second guide block 18 on the top of the collection tank 10 have the same function: to prevent paint from falling into the gaps inside the grinding chamber 1 and causing paint waste.
[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
