[0004] In the aforementioned prior art, there is no sieving device for excess dye during the silica gel coloring process. Excess dye solution reduces the viscosity of the silica gel, causing pigment particles to settle during static curing, resulting in a layered effect where the color is lighter at the top and darker at the bottom; color spots or streaks appear on the surface, affecting the coloring effect.

[0005] To address the aforementioned problems, this utility model proposes a silicone coloring device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, the technical solution adopted by this utility model is as follows: a silicone coloring device. It includes a mixing tank 1. Materials are placed into the mixing tank 1 for mixing and coloring.

[0028] An annular box 9 is fixedly installed at the top of the interior of the mixing tank 1. Multiple nozzles 10 facing into the mixing tank 1 are provided on the annular box 9. A liquid supply pipe 8 communicating with the annular box 9 is fixedly installed on the mixing tank 1.

[0029] The coloring solution is injected into the annular box 9 through the supply pipe 8 and sprayed into the mixing tank 1 through the nozzle 10, thus spraying the coloring solution onto the parts in the mixing tank 1.

[0030] A sieve plate 13 is fixedly installed inside the mixing tank 1. The sieve plate 13 is used to filter out smaller material particles and excess coloring liquid. An outwardly inclined discharge plate 2 is installed on the side wall of the mixing tank 1. The colored material is taken out from the discharge plate 2. Furthermore, the uppermost end of the discharge plate 2 is aligned with the upper surface of the sieve plate 13.

[0031] As an optional embodiment, a T-shaped sliding plate is vertically slidably installed on the side wall of the mixing tank 1 corresponding to the discharge plate 2 at the discharge port. The sliding plate is driven by a cylinder. The cylinder causes the sliding plate to move up and down to open or close the discharge plate 2.

[0032] A feed pipe 5, communicating with the inner cavity of the mixing tank 1, is fixedly installed on the top of the mixing tank 1. A discharge pipe 3 is installed at the bottom of the mixing tank 1. Material is fed into the mixing tank 1 through the feed pipe 5, and excess coloring solution is discharged through the discharge pipe 3.

[0033] Furthermore, the bottom of the mixing tank 1 is sloping, with a lower height near the discharge pipe 3 and a higher height away from the discharge pipe 3.

[0034] The bottom of the mixing tank 1 is inclined so that the coloring solution can flow smoothly out of the discharge pipe 3.

[0035] A stirring shaft 11 with its axis vertically oriented is rotatably mounted inside the stirring tank 1. Multiple stirring blades 12 are evenly distributed and fixedly mounted on the stirring shaft 11, and the stirring blades 12 are arc-shaped. The stirring blades 12 are positioned on the stirring shaft 11 above the sieve plate 13.

[0036] Specifically, a motor 7 is fixedly installed on the upper end of the mixing tank 1. The output shaft of the motor 7 is arranged in a vertical direction. The output shaft of the motor 7 is fixedly connected to the mixing shaft 11.

[0037] The material is placed onto the sieve plate 13, and while the coloring solution is being sprayed, the motor 7 is started, driving the stirring shaft 11 to rotate. The stirring shaft 11 drives the stirring blades 12 to rotate together, and the stirring blades 12 stir the material in the mixing tank 1, so that the material can be colored more evenly. The stirring blades 12 are set in an arc shape, and during the stirring process, they gather the material closer to the center area of ​​the sieve plate 13, so as to facilitate the uniform mixing of the material and the coloring solution.

[0038] The lower end of the stirring shaft 11 passes through the sieve plate 13 and is located below the sieve plate 13. A first driving component that drives the sieve plate 13 to vibrate up and down is installed between the stirring shaft 11 and the stirring tank 1.

[0039] During the rotation of the stirring shaft 11, the first drive component is activated, causing it to strike the sieve plate 13, which in turn causes the sieve plate 13 to vibrate, thus preventing clogging.

[0040] Specifically, the first drive component includes: a support frame 14, an impact block 15, and a fixing block 16.

[0041] The support frame 14 is fixedly connected to the stirring shaft 11 via a connecting rod. The support frame 14 is located below the sieve plate 13.

[0042] Multiple impact blocks 15 are provided. The multiple impact blocks 15 are evenly distributed along the circumference of the support frame 14. The impact blocks 15 are vertically slidably connected to the support frame 14. The upper end of the impact block 15 is located between the sieve plate 13 and the support frame 14, and the lower end of the impact block 15 is spherical and located at the lower end of the support frame 14.

[0043] Multiple fixing blocks 16 are provided. The fixing blocks 16 are fixed to the side wall of the mixing tank 1. The fixing blocks 16 are wedge-shaped blocks with a higher center and lower sides. The impact block 15 cooperates with the fixing blocks 16.

[0044] The stirring shaft 11 rotates, causing the support frame 14 and the impact block 15 to rotate together. As the impact block 15 rotates, its lower end contacts the fixing block 16. During the rotation of the impact block 15 with the support frame 14, the wedge-shaped block of the fixing block 16 causes the impact block 15 to move up and down. The upward movement of the impact block 15 strikes the sieve plate 13, causing the sieve plate 13 to vibrate.

[0045] As an optional embodiment, the support frame 14 has a vertical through hole, the impact block 15 is set as a T-shaped rod, the upper end of the T-shaped rod is located between the support frame 14 and the sieve plate 13, and the upper end of the T-shaped rod is configured as a gravity block.

[0046] When the impact block 15 initially contacts the fixed block 16, the fixed block 16, being higher in the middle and lower on both sides, pushes the impact block 15 upward. Once the impact block 15 contacts the middle of the fixed block 16, it reaches its highest displacement position. The impact block 15 continues to rotate along with the support frame 14, and under the action of the inclined surface of the fixed block 16 and the gravity block of the impact block 15, it moves downward.

[0047] As an alternative embodiment, the support frame 14 has a vertical through hole, the impact block 15 is configured as a T-shaped rod, the upper end of the T-shaped rod is located between the support frame 14 and the sieve plate 13, and a spring is sleeved on the impact block 15, with one end of the spring fixed to the impact block 15 and the other end of the spring fixed to the support frame 14.

[0048] Similarly, when the impact block 15 initially contacts the fixed block 16, because the middle of the fixed block 16 is higher than the sides, the fixed block 16 pushes the impact block 15 upward. When the impact block 15 contacts the middle of the fixed block 16, the impact block 15 reaches its highest displacement position. The impact block 15 continues to rotate with the support frame 14, and under the action of the inclined surface of the fixed block 16 and the spring, the impact block 15 moves downward.

[0049] The discharge pipe 3 is positioned offset from the central axis of the mixing tank 1. A scraper 21 is fixedly installed at the bottom of the mixing shaft 11. The scraper 21 includes two scraper rods. The two scraper rods are fixedly connected and form an angle between them, making the scraper 21 generally V-shaped. The connection point between the two scraper rods is located on the circumferential surface of the discharge pipe 3.

[0050] A certain angle is set between the two scraper rods of scraper 21. The specific angle should be selected between 120° and 150°. The rotation direction of stirring shaft 11 is away from the vertex of the angle formed by the two scraper rods.

[0051] As the scraper 21 rotates with the stirring shaft 11, it scrapes away the coloring solution near the bottom of the mixing tank 1. During the rotation of the scraper 21, it guides the coloring solution to the vicinity of the circumferential surface of the discharge pipe 3, so that the coloring solution can flow out from the discharge pipe 3.

[0052] A base 4 is provided below the mixing tank 1, and a second drive assembly for driving the mixing tank 1 to slide horizontally is installed between the base 4 and the stirring shaft 11.

[0053] When the stirring shaft 11 rotates, it drives the stirring tank 1 to slide horizontally via the second drive assembly. During the stirring and coloring process, the material in the stirring tank 1 slides horizontally, which can further achieve uniform coloring.

[0054] Specifically, the upper end of the base 4 is provided with a horizontal first groove 6, and the lower end of the mixing tank 1 is fixedly installed with a roller 17. The roller 17 is located in the first groove 6 and is in rolling contact with the first groove 6.

[0055] Furthermore, the second drive assembly includes an incomplete gear 18 and a rack 19.

[0056] Wherein: the upper end of the base 4 has a second groove 20 parallel to the length direction of the first groove 6. The lower end of the stirring shaft 11 passes through the second groove 20 and is located inside the base 4. The stirring shaft 11 is slidably disposed with the second groove 20, and the incomplete gear 18 is fixedly installed at the lower end of the stirring shaft 11.

[0057] Two racks 19 are provided. The racks 19 are parallel to the length direction of the second slide groove 20. The two racks 19 are respectively disposed on both sides of the second slide groove 20. The racks 19 mesh with the incomplete gear 18.

[0058] The rotation of the stirring shaft 11 drives the incomplete gear 18 to rotate together. When the incomplete gear 18 rotates, it intermittently meshes with the rack 19 on different sides, causing the stirring tank 1 to move horizontally back and forth.

[0059] The specific method of using the silicone coloring device described in this application is as follows:

[0060] The material is added to the upper surface of the sieve plate 13 inside the mixing tank 1 through the feed pipe 5. The coloring solution is evenly sprayed into the mixing tank 1 through the annular box 9 and the nozzle 10.

[0061] Start motor 7, and the output shaft of motor 7 drives the stirring shaft 11 to rotate. The stirring shaft 11 causes the stirring blades 12 to rotate, so as to gather the material above the sieve plate 13 towards the center area of ​​the sieve plate 13 so that the material and the coloring solution can be mixed evenly.

[0062] The stirring shaft 11 rotates, causing the support frame 14 and the impact block 15 to rotate together. As the impact block 15 rotates, its lower end contacts the fixing block 16. During the rotation of the impact block 15 with the support frame 14, the wedge-shaped block of the fixing block 16 causes the impact block 15 to move up and down. The upward movement of the impact block 15 strikes the sieve plate 13, causing it to vibrate and preventing clogging.

[0063] As the scraper 21 rotates with the stirring shaft 11, it scrapes away the coloring solution near the bottom of the mixing tank 1. During the rotation of the scraper 21, it guides the coloring solution to the vicinity of the circumferential surface of the discharge pipe 3, so that the coloring solution can flow out from the discharge pipe 3.

[0064] Simultaneously, the stirring shaft 11 causes the incomplete gear 18 to rotate. The incomplete gear 18 intermittently meshes with the racks 19 on both sides of the incomplete gear 18, causing the mixing tank 1 to reciprocate along the first chute 6 to accelerate the rate of uniform mixing of the material and the coloring solution. At the same time, the sieve plate 13 separates materials that do not meet the requirements and excess coloring solution.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
