[0027] The following is combined with Figure 1-Figure 4 The utility model is described in further detail.

[0028] See also Figure 1-Figure 4The utility model provides an embodiment of a quick-drying paint raw material grinding device with a screening mechanism: a quick-drying paint raw material grinding device with a screening mechanism, comprising a screening and grinding device body 1, the screening and grinding device body 1 is used to screen and grind the paint raw materials; a feed pipe 2, the feed pipe 2 is fixed to the top of the screening and grinding device body 1 by bolts, and the feed pipe 2 is used to guide the raw materials; a storage box 3, the storage box 3 is fixed to the top of the feed pipe 2 by bolts, and the storage box 3 is used to store the raw materials; a feeding mechanism 4, a feed The feeding mechanism 4 is arranged at the top of the storage box 3, and the feeding mechanism 4 passes through the storage box 3 and extends to the inside of the feeding pipe 2. The feeding mechanism 4 is used to stir the raw materials in the storage box 3 and quantitatively transport the raw materials to the screening and grinding device body 1. The feeding mechanism 4 includes a rotating rod 402 arranged inside the storage box 3. The outer wall of the rotating rod 402 is fixed with a stirring blade 403 by bolts. The bottom end of the rotating rod 402 is sleeved with a guide block 404. The stirring blade 403 is used to break up and stir the raw materials, and the guide block 404 is used for quantitative transportation of the raw materials.

[0029] It can be further explained that, during one reciprocating movement of the material guide block 404, the raw materials are quantitatively transported to the screening and grinding device body 1, thereby improving the grinding and screening efficiency of the raw materials in the screening and grinding device body 1. At the same time, the stirring blade 403 is driven to rotate by the same power source to stir the raw materials stored in the storage box 3, thereby avoiding the adhesion of the raw materials and ensuring the stability and smoothness of the raw material transportation.

[0030] See also Figure 2 and Figure 3 The feeding mechanism 4 also includes a driving motor 401 fixed to the top of the storage box 3 by bolts, the output end of the driving motor 401 is connected to the top of the rotating rod 402 through a coupling, the rotating rod 402 is rotatably connected to the inner wall of the storage box 3 through a bearing, and a plurality of stirring blades 403 are provided, and the plurality of stirring blades 403 are evenly distributed on the outer wall of the rotating rod 402.

[0031] It can be further explained that the output end of the driving motor 401 rotates to drive the rotating rod 402 to rotate, and the rotating rod 402 rotates to drive multiple groups of stirring blades 403 to rotate. The stirring blades 403 rotate and stir the raw materials in the storage box 3 to prevent the raw materials from sticking together, thereby ensuring the normal conveying operation of subsequent raw materials.

[0032] See also Figure 2 and Figure 4 The inner wall of the feed pipe 2 is provided with a moving groove 4043, and the moving groove 4043 matches the moving track of the guide block 404. The inner wall of the guide block 404 is provided with two guide grooves 4042, and the two guide grooves 4042 are symmetrically distributed at both ends of the rotating rod 402. The guide grooves 4042 are used to transport raw materials and guide the raw materials from the storage box 3 into the screening and grinding device body 1. The moving groove 4043 is used for the vertical movement of the guide block 404; the bottom end of the rotating rod 402 is welded with a rotating column 405, and the rotating column 405 is located inside the guide block 404, and the guide block The inner wall of 404 is fixed with a connecting block 4041 by bolts, and the connecting block 4041 is sleeved on the outer wall of the rotating column 405. Through the arrangement of the rotating rod 402, the rotating column 405 and the connecting block 4041, it is convenient for the rotating rod 402 to rotate and drive the guide block 404 to move vertically; the outer wall of the rotating column 405 is provided with a threaded groove in opposite directions, and the interior of the connecting block 4041 is provided with a crescent pin sleeved with the threaded groove. Through the arrangement of the threaded groove and the crescent pin, it is convenient for the rotating column 405 to rotate and drive the connecting block 4041 and the guide block 404 to move back and forth in the vertical direction.

[0033] It can be further explained that the rotation of the rotating rod 402 drives the rotating column 405 to rotate at the same time. The rotation of the rotating column 405 drives the guide block 404 to move back and forth in the vertical direction through mechanical transmission. During the reciprocating movement of the guide block 404, the raw materials are quantitatively transported to the screening and grinding device body 1, thereby improving the grinding and screening efficiency of the raw materials in the screening and grinding device body 1.

[0034] Working principle: when in use, first place the raw materials to be ground inside the material storage box 3, then the staff controls the driving motor 401 to work, the output end of the driving motor 401 rotates to drive the rotating rod 402 to rotate, the rotating rod 402 rotates to drive multiple groups of stirring blades 403 to rotate, the stirring blades 403 rotate and stir the raw materials in the material storage box 3 to avoid the raw materials from sticking together, thereby ensuring the normal conveying operation of the subsequent raw materials;

[0035] Secondly, the rotation of the rotating rod 402 drives the rotating column 405 to rotate at the same time, and the rotation of the rotating column 405 drives the crescent pin inside the connecting block 4041 to move upward, and the crescent pin moves and drives the connecting block 4041 to move upward, and the connecting block 4041 moves to drive the guide block 404 to move, and the guide block 404 moves to drive the guide trough 4042 to move. When the guide trough 4042 moves to the inside of the material storage box 3 and disengages from the moving trough 4043, the raw materials in the material storage box 3 enter the guide trough 4042, and then pass through The guide groove 4042 enters the feed pipe 2, and then enters the screening and grinding device body 1 through the feed pipe 2. After the connecting block 4041 moves to the top of the thread groove on the outer wall of the rotating column 405, the connecting block 4041 is reset and moves downward under the action of the internal crescent pin and the thread groove on the outer wall of the rotating column 405. The connecting block 4041 resets and moves and drives the guide block 404 to reset and move through mechanical transmission. At this time, the raw materials in the storage box 3 cannot enter the screening and grinding device body 1 through the guide block 404, and so on.

[0036] Finally, through the reciprocating movement of the guide block 404 in the vertical direction, the guide trough 4042 also reciprocates in the vertical direction. When the guide trough 4042 is disengaged from the movable trough 4043, the raw materials in the storage box 3 can enter the screening and grinding device body 1 through the feeding pipe 2. When the guide trough 4042 is reset, the raw materials cannot enter the screening and grinding device body 1. In this way, during the reciprocating movement of the guide block 404, the raw materials are quantitatively transported to the screening and grinding device body 1. Therefore, the grinding and screening efficiency of the raw materials in the screening and grinding device body 1 is improved. At the same time, the stirring blade 403 is driven to rotate by the same power source to stir the raw materials stored in the storage box 3, avoid the adhesion of the raw materials, and ensure the stability and smoothness of the raw material transportation.
