[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-3 The utility model provides a technical solution: a raw material screening device for powder coating production, comprising a support cylinder 1, a support block 3 is connected to the outer wall of the support cylinder 1, a support column 9 is connected to the top of the support block 3, a fixed plate 10 is connected to the other end of the support column 9, and an anti-blocking mechanism 5 is arranged on the top of the fixed plate 10;
[0027] The anti-blocking mechanism 5 includes a first motor 501 and multiple fixed blocks 502. One side of the first motor 501 is connected to the top of the fixed plate 10. The output shaft of the first motor 501 passes through one side of the fixed plate 10 and is connected to a rotating rod 505. Two first connecting plates 503 are connected to the outer wall of the rotating rod 505. A knocking block 504 is connected to the bottom of the first connecting plate 503. Multiple springs 2 are connected to the top of the support tube 1, and the other ends of the multiple springs 2 are connected to the same discharge box 4. A screening box 8 is connected to the top of the discharge box 4, and a plurality of filtering holes 11 are provided at the bottom of the inner wall of the screening box 8.
[0028] The specific implementation method is as follows: by setting an anti-blocking mechanism 5, the rotating rod 505 is driven to rotate by rotating the output shaft of the first motor 501, and the rotating rod 505 rotates to drive the two first connecting plates 503 to rotate, and drives the knocking block 504 to rotate. The knocking block 504 will collide with the outermost fixed block 502 when it rotates. By setting an inclined surface on one side of the knocking block 504 and inclined surfaces on both sides of the fixed block 502, when the knocking block 504 collides with the fixed block 502, the fixed block 502 will drive the screening box 8 to vibrate in the longitudinal direction, so that the raw materials adhered to the filter holes 11 can be shaken off, thereby avoiding the raw materials blocking the filter holes 11 and making the machine unable to work normally. At the same time, the longitudinal vibration can give the raw materials a longitudinal force, thereby better promoting the separation of the raw materials and impurities, thereby improving the screening efficiency.
[0029] The bottoms of the multiple fixed blocks 502 are all connected to the bottom of the inner wall of the screening box 8, and two crushing mechanisms 6 are arranged on the outer wall of the rotating rod 505. The crushing mechanism 6 includes a second connecting plate 601, and one side of the second connecting plate 601 is connected to the outer wall of the rotating rod 505. The bottom of the second connecting plate 601 is connected to multiple crushing blocks 602, and the bottom of the crushing blocks 602 is fitted with the bottom of the inner wall of the screening box 8. The outer wall of the screening box 8 is provided with a switch mechanism 7, and the switch mechanism 7 includes a slider 704. The bottom of the slider 704 is provided with a slide groove 703, and the inner wall of the slide groove 703 is slidably connected to the outer wall of the screening box 8. The top of the slider 704 is provided with a threaded groove, and the inner wall of the threaded groove is threadedly connected with a threaded rod 702, one end of the threaded rod 702 extends into the slide groove 703 and is rotatably connected to the top of the screening box 8, and the other end of the threaded rod 702 extends outside the threaded groove and is connected with a knob 701. The bottom of the discharging box 4 is connected to a second motor 12, and the output shaft of the second motor 12 is connected to an eccentric block 13.
[0030] The specific implementation method is as follows: by setting a crushing mechanism 6, the output shaft of the first motor 501 drives the rotating rod 505 to rotate, while the rotating rod 505 also drives the second connecting plate 601 to rotate, and the rotation of the second connecting plate 601 drives the multiple crushing blocks 602 to rotate. Since there is a certain distance between two adjacent crushing blocks 602, the agglomerated raw materials will be driven to move to the fixed blocks 502. Since the fixed blocks 502 and the crushing blocks 602 are staggered, the agglomerated raw materials can be crushed and decomposed into fine particles. Therefore, it can be screened by the machine, avoiding the operation of crushing the agglomerated raw materials separately, and improving work efficiency. Since the device as a whole is inclined at a certain angle, the impurities and raw materials after screening will go out from the impurity outlet and the material outlet. By setting the switch mechanism 7, the threaded rod 702 is rotated by twisting the knob 701, so that the slider 704 can be driven to move up and down, so that the slider 704 can block the impurity outlet of the screening box 8 to prevent the raw materials from leaking out of the impurity outlet, so that the raw materials can be screened for a long time in the screening box 8, thereby improving the screening effect.
[0031] Working principle: When in use, pour the raw material into the screening box 8, and then start the first motor 501 and the second motor 12. The output shaft of the second motor 12 drives the eccentric block 13 to rotate, so that the device vibrates, and then the raw material in the screening box 8 is screened. At the same time, the output shaft of the first motor 501 drives the rotating rod 505 to rotate, and the rotating rod 505 simultaneously drives the first connecting plate 503 and the second connecting plate 601 to rotate, and drives the knocking block 504 and the crushing block 602 to rotate. The knocking block 504 will collide with the outermost fixed block 502 to make the screening box 8 vibrate longitudinally, thereby shaking off the raw material adhered to the filter hole 11, and the crushing block 602 will drive the agglomerated raw material to move to the fixed block 502, thereby crushing the agglomerated raw material so that it can be screened. After the screening is completed, impurities and raw materials will go out from the impurity outlet and the material outlet. By twisting the knob 701, the slider 704 can be driven to close and open the impurity outlet.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
