DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-5 , a raw material screening device for coating processing comprises a box body 1, a feeding port 2 is fixedly connected to the top of the box body 1, a dust suction box 3 is fixedly connected to both sides of the interior of the box body 1, a suction fan 4 is rotatably connected to the interior of the dust suction box 3, a dust suction pipe 5 is fixedly connected to the upper part of the interior of the dust suction box 3 and extends to the outside of the box body 1, a sieve plate 9 is fixedly connected to the lower part of the interior of the box body 1, a partition 24 is fixedly connected to the interior of the box body 1 and located below the dust suction box 3, a funnel 25 is fixedly connected to the interior of the partition 24, slide bars 6 are symmetrically slidably connected to both sides of the interior of the partition 24, a limiting block 7 is fixedly connected to the bottom of the slide bar 6, a push block 8 is provided below the limiting block 7, a first screen 10 is fixedly connected to both sides of the interior of the sieve plate 9, a second screen 11 is fixedly connected to the interior of the sieve plate 9 and located on both sides of the first screen 10, the aperture of the second screen 11 is larger than the aperture of the first screen 10, and a transmission mechanism is provided on both sides of the interior of the box body 1.

[0023] Specifically, the transmission mechanism includes a motor 13 and a transmission unit. The motor 13 is fixedly connected to both sides of the outside of the box body 1. The output end of the motor 13 extends to the inside of the box body 1 and is fixedly connected to a rotating rod 14. One end of the rotating rod 14 is fixedly connected to a cam 15. The outer side of the cam 15 is fixedly connected to a sliding shaft 16. The sliding shaft 16 is slidably connected to the inside of the limit block 7. The suction fan 4 is rotated through the transmission unit. The transmission unit includes a first pulley 17. The outside of the rotating rod 14 is fixedly connected to the first pulley 17. The outside of the suction fan 4 is fixedly connected to the second pulley 18. The first pulley 17 and the second pulley 18 pass through the dust box 3 and the inner wall of the partition 24 through a transmission belt 19 for transmission connection.

[0024] Through the above technical scheme, firstly, the two motors 13 are started through the control panel 27, and then the raw materials for coating processing are put into the box body 1 through the feed port 2. In the process of the raw materials falling, the output end of the motor 13 can drive the first pulley 17 to rotate, and the first pulley 17 then drives the suction fan 4 to rotate through the second pulley 18 and the transmission belt 19, so that the suction fan 4 absorbs impurities such as dust and debris in the raw materials. Since the raw materials are granular and block-shaped, the weight and volume are greater than the dust and debris, and therefore they will not be absorbed. After the dust and debris are sucked into the dust suction box 3, they are discharged to the outside of the box body 1 through the dust suction pipe 5. Then the raw materials fall to the top of the sieve plate 9 through the funnel 25, and slide downward through the inclined surfaces on both sides of the sieve plate 9. While running, the motor 13 can drive the rotating rod 14 to rotate, so that the rotating rod 14 drives the cam 15 to rotate, and the cam 15 drives the sliding shaft 16 to slide inside the limit block 7, so that the limit block 7 is driven by the cam 15 and moves back and forth through the limit of the slide bar 6, thereby driving the push block 8 below to hammer the sieve plate 9 back and forth, so that the sieve plate 9 vibrates, thereby driving the raw materials on the top to vibrate, thereby improving the screening effect. The first screen 10 can first screen the small-particle raw materials and make them fall into the first collecting chamber inside the collecting frame 12, and then the remaining large-particle raw materials are screened by the second screen 11 into the second collecting chamber inside the collecting frame 12. The device can adsorb dust on the raw materials for coating processing before screening them, and absorb impurities such as dust and debris in the raw materials to prevent them from being mixed in the raw materials and affecting the molding quality of the coating when the raw materials are used to produce coatings. The first screen 10 and the second screen 11 set inside the sieve plate 9 can screen granular raw materials of different volumes, which can reduce the burden of manual screening, and after screening, it is beneficial to improve the mixing efficiency of the raw materials.

[0025] Specifically, a grille is provided on one side of the outside of the dust box 3 close to the dust pipe 5 , and a filter screen 23 is fixedly connected to the inside of the box body 1 and located between the dust pipe 5 and the suction fan 4 .

[0026] Through the above technical solution, the set grille can block some of the smaller raw material particles carried during the impurity removal process, and the set filter 23 can prevent impurities from being sucked into the interior of the suction fan 4 and causing damage to the suction fan 4.

[0027] Specifically, the bottom of the limit block 7 is fixedly connected to the connecting block 20, and the inside of the connecting block 20 is slidably connected to the slide plate 21. Springs 22 are equidistantly arranged inside the connecting block 20 and above the slide plate 21. The bottom of the slide plate 21 extends to the bottom of the connecting block 20 and is fixedly connected to the push block 8, and the push block 8 is slidably connected to the inner wall of the connecting block 20.

[0028] Through the above technical solution, the elasticity of the spring 22 can buffer the push block 8 during the hammering process, thereby preventing the push block 8 or the sieve plate 9 from being damaged after long-term work.

[0029] Specifically, a collecting frame 12 is provided inside the box 1 and below the sieve plate 9, a first collecting cavity is provided inside the collecting frame 12 and below the first sieve 10, and a second collecting cavity is provided inside the collecting frame 12 and on both sides of the first collecting cavity.

[0030] Through the above technical solution, the first collecting chamber and the second collecting chamber which are separately arranged can cooperate with the first screen 10 and the second screen 11 to screen and collect the raw material particles of two different sizes.

[0031] Specifically, a box door 26 is installed on the outside of the box body 1, a control panel 27 is installed on the outer side of the box door 26, both motors 13 are electrically connected to the control panel 27, and a handle is fixedly connected to the outer side of the box door 26.

[0032] Through the above technical solution, when the screened raw materials need to be taken, the box door 26 can be opened to pull out the collection frame 12 for use, and the control panel 27 provided can facilitate the staff to quickly control the two motors 13.

[0033] When in use, first start the two motors 13 through the control panel 27, and then put the raw materials for coating processing into the box body 1 through the feed port 2. In the process of the raw materials falling, the output end of the motor 13 can drive the first pulley 17 to rotate, and the first pulley 17 drives the suction fan 4 to rotate through the second pulley 18 and the transmission belt 19, so that the suction fan 4 absorbs impurities such as dust and debris in the raw materials. Since the raw materials are granular and block-shaped, the weight and volume are greater than the dust and debris, and therefore they will not be absorbed. After being sucked into the dust box 3, the debris is discharged from the outside of the box body 1 through the dust pipe 5, and then the raw materials fall to the top of the sieve plate 9 through the funnel 25, and slide downward through the inclined surfaces on both sides of the sieve plate 9. The motor 13 can drive the rotating rod 14 to rotate while running, so that the rotating rod 14 drives the cam 15 to rotate, and the cam 15 drives the sliding shaft 16 to slide inside the limit block 7, so that the limit block 7 is driven by the cam 15 and through the limit of the slide rod 6 to perform reciprocating up and down motion, thereby driving the push block 8 below to push the sieve plate 9 forward and backward. The hammer is hammered down again, so that the screening plate 9 vibrates, thereby driving the raw materials on the top to vibrate and improving the screening effect. The first screen 10 can first screen out small-particle raw materials and make them fall into the first collecting chamber inside the collecting frame 12, and then the remaining large-particle raw materials are screened by the second screen 11 and fall into the second collecting chamber inside the collecting frame 12. The set grid can block some of the smaller raw material particles carried in the process of impurity absorption, and the set filter 23 can prevent impurities from being sucked into the suction fan 4 and causing damage to the suction fan 4. The elasticity of the set spring 22 can buffer the push block 8 during the hammering process to prevent the push block 8 or the screening plate 9 from being damaged after long-term work. The first collecting chamber and the second collecting chamber that are separately set can cooperate with the first screen 10 and the second screen 11 to screen and collect two raw material particles of different sizes. When the screened raw materials need to be taken, the box door 26 can be opened to pull out the collection frame 12 for use, and the control panel 27 can be used to facilitate the staff to quickly control the two motors 13.
