DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-9 , a feeding device for the production of an anti-static topcoat, including: a gland 1, a motor 2 is installed in the middle of the gland 1, the output shaft of the motor 2 is installed with a main shaft 6 through a coupling, the bottom end of the main shaft 6 penetrates the gland 1, a powder-beating roller 7 is sleeved on the surface of the main shaft 6 through a bearing, a gear set 8 is arranged between the powder-beating roller 7 and the gland 1, a sieve cover 5 is rotatably sleeved on the surface of the main shaft 6 at the bottom end of the powder-beating roller 7, a spring vibration frame 9 is clamped at the bottom end of the sieve cover 5, and a stirring frame 4 is installed at the bottom end of the main shaft 6;

[0029] A pressure cover cylinder 3 is installed at the bottom of the gland 1 near the outer edge, the structure on the outer edge of the spring vibration frame 9 is installed on the inner wall of the pressure cover cylinder 3, the bottom end of the pressure cover cylinder 3 covers the mixing barrel for producing the anti-static topcoat, a feed hopper 10 is arranged on the gland 1, and the bottom end of the feed hopper 10 penetrates through the gland 1 and part of the structure of the gear set 8 respectively and is communicated with the internal space of the sieve cover 5.

[0030] Among them, the gear set 8 includes a gear cover 81, the gear cover 81 is installed at the bottom of the gland 1, and the top end of the powder-beating roller 7 penetrates through the gear cover 81 and is rotatably arranged therewith. The top of the sieve cover 5 is blocked by the gear cover 81 to prevent powder from entering the gear set 8 during the operation of the powder-beating roller 7 and affecting the smoothness of its operating structure.

[0031] Among them, a gear shaft 82 is rotatably arranged between the gear cover 81 and the gland 1. The surface of the gear shaft 82 is sleeved with a first gear 83 and a second gear 84 respectively. The outer edge of the first gear 83 meshes with a third gear 85, the third gear 85 is sleeved on the main shaft 6, the outer edge of the second gear 84 meshes with a fourth gear 86, and the fourth gear 86 is sleeved on the end of the powder-beating roller 7 penetrating through the gear cover 81. By using the meshing ability between multiple gears, the rotational force of the main shaft 6 is transmitted to the powder-beating roller 7, so that while the powder-beating roller 7 rotates along with the operation of the main shaft 6, its rotational speed can be independent of the main shaft 6.

[0032] Among them, the diameter of the third gear 85 is three times the diameter of the first gear 83, and the diameters of the second gear 84 and the fourth gear 86 are the same. By using the difference in diameters between multiple gears, after the rotational force of the main shaft 6 is transmitted to the powder-beating roller 7, the rotational speed is magnified three times, thereby meeting the rotational speed required for the powder-beating roller 7 to break particles.

[0033] Among them, the sieve cover 5 includes a cover body 51. The cover body 51 is rotatably sleeved on the main shaft 6. A moving top ring 52 is integrally formed in the middle of the inner wall of the cover body 51. A fixed top ring 53 is sleeved on the main shaft 6. Ladder-shaped convex teeth are integrally formed on the opposite surfaces of the moving top ring 52 and the fixed top ring 53. The ladder-shaped convex teeth of the moving top ring 52 and the fixed top ring 53 are mutually overlapped. By using the rotation of the fixed top ring 53 along with the main shaft 6, continuous impacts occur on the contact surface with the moving top ring 52, and in cooperation with the elastic vibration frame 9, the sieve cover 5 is continuously jittered, improving the efficiency of sieving powder.

[0034] Among them, the elastic vibration frame 9 includes an inner ring frame 91. The inner ring frame 91 is rotatably sleeved on the main shaft 6. A limiting rod 92 is arranged at the top of the inner ring frame 91. A limiting hole 93 is opened at the bottom of the sieve cover 5. The top end of the limiting rod 92 is slidably inserted into the limiting hole 93. A compression spring 94 is sleeved on the outer edge of the limiting rod 92. The top end and the bottom end of the compression spring 94 are respectively lapped with the sieve cover 5 and the inner ring frame 91. A support rod 95 is integrally arranged on the outer edge of the inner ring frame 91. The end of the support rod 95 away from the inner ring frame 91 is provided with an outer ring frame 96. The outer ring frame 96 is installed on the inner wall of the pressing cover cylinder 3. By setting the elastic vibration frame 9, not only the position of the sieve cover 5 is clamped by the limiting rod 92 to prevent the sieve cover 5 from rotating along with the main shaft 6, but also after the sieve cover 5 receives an impact force, the compression spring 94 gives the sieve cover 5 an up-and-down bouncing force, thereby enabling the sieve cover 5 to have the ability to jitter.

[0035] Among them, the stirring frame 4 includes a stirring shaft 41. A coaxial connector 42 is integrally arranged at the top end of the stirring shaft 41. Multiple groups of stirring rods 43 are sleeved on the surface of the stirring shaft 41 near the bottom end. The stirring rods 43 are located in the mixing barrel for producing anti-static topcoat. By using the coaxial connector 42 at the top end of the stirring shaft 41, the stirring frame 4 and the main shaft 6 are designed to be detachable. When facing mixing barrels of different specifications, different-sized stirring frames 4 can be correspondingly replaced, thereby improving the adaptability of the feeding device.

[0036] Among them, the pressing cover cylinder 3 includes a cylinder body 31. The cylinder body 31 is installed at the bottom of the pressing cover 1 and covers the outside of the sieve cover 5. Handles 32 are installed on both sides of the cylinder body 31. By using the pressing cover cylinder 3 to cover the side of the sieve cover 5, the powder sieved out from the side of the sieve cover 5 can fall into the mixing barrel. At the same time, by lifting the handle 32, it is possible to freely select which mixing barrel to place the feeding device on, enabling the feeding device to be immediately moved to the next mixing barrel for use after completing the feeding of one mixing barrel.

[0037] Working principle: When using the feeding device, first install the stirring frame 4 at the bottom end of the main shaft 6, then lift the pressing cover cylinder 3 and place it on the mixing barrel after liquid materials are put in. Start the motor 2 to mix various different powdery materials and pour them into the feeding device through the feeding hopper 10. At this time, the powdery materials fall into the sieve cover 5. With the oscillation of the sieve cover 5 by the elastic oscillation frame 9, the powders meeting the stirring conditions leak into the mixing barrel through the pores of the sieve cover 5. At the same time, the gear set 8 amplifies the rotational force of the main shaft 6 and transmits it to the powder crushing roller 7 to crush the powdery materials that have formed into particles, and then screen them through the sieve cover 5 until the powdery materials fully meet the stirring conditions.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
