DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, a color paste mixing device includes a mixing barrel 1, a ring sleeve 12, a main core body 2, and a sliding ring 7. The mixing barrel 1 is cylindrical and has an axial upper end open. The upper end of the mixing barrel 1 is a feeding direction side, and the lower end of the mixing barrel 1 is a discharging direction side after mixing. The lower end is provided with a discharge port and a discharge valve installed. The color paste can be discharged after the valve is opened.

[0029] like Figure 1As shown, the main core body 2 is inserted into the mixing barrel 1, and the upper end of the main core body 2 is exposed from the upper end of the mixing barrel 1. The mixing barrel 1 and the main core body 2 are coaxially arranged. The bottom of the main core body 2 is connected to the motor 8, and the main core body 2 is driven by the motor 8 to rotate along its own axis. The lower part of the main core body 2 is a cylindrical structure. The main core body 2 includes a convex body 21 located at the top and a convex body 22 at the lower end of the convex body 21. The convex body 21 is a cylindrical structure, and the convex body 22 is a conical structure. The outer wall surface of the convex body 22 is a conical surface with a small diameter at the upper end and a large diameter at the lower end.

[0030] like Figure 1 As shown, the convex body 21 is fixedly mounted with a flow guide component 3, which is inserted into the convex body 21. The flow guide component 3 includes a bottom plate 33 at the bottom, and the inner peripheral wall of the bottom plate 33 is attached to and fixed to the outer peripheral wall of the convex body 21. The flow guide component 3 rotates synchronously with the convex body 21.

[0031] The flow guide component 3 includes a feed port 1 31 and a feed port 2 32. The feed port 1 31 and the feed port 2 32 are both through-connected and annular. The feed port 1 31 is located radially outside the feed port 2 32. The color paste solvent is placed in the feed port 1 31, and the iron oxide powder is placed in the feed port 2 32. The color paste solvent and the iron oxide powder are mixed to form a color paste. A conduit 4 is installed on one side of the flow guide component 3. The conduit 4 is connected to the feed port 1 31, and the color paste solvent in the feed port 1 31 flows downward through the conduit 4.

[0032] like Figure 1 As shown, a support ring 11 is installed on the inner wall of the mixing barrel 1. The support ring 11 is a circular ring structure. The outer peripheral wall of the support ring 11 is attached to and fixed to the inner peripheral wall of the mixing barrel 1. The support ring 11 is provided with a guide hole 111. The guide hole 111 passes through the support ring 11 from top to bottom. A plurality of guide holes 111 are evenly distributed along the circumference of the support ring 11. The conduit 4 is located above the support ring 11, and the color paste solvent guided downward by the conduit 4 can flow downward along the guide hole 111.

[0033] like Figure 2 , Figure 6 As shown, one side of the bottom plate 33 is provided with an axially penetrating through hole 1 331, and the through hole 1 331 is installed with a distribution plate 5, and the distribution plate 5 is provided with a through hole 2 51, and the through hole 2 51 passes through the distribution plate 5 up and down, and the upper end of the through hole 2 51 is connected with the feed port 2 32, and the iron oxide powder in the feed port 2 32 flows downward from the through hole 2 51.

[0034] like Figure 1 As shown, the inner wall of the support ring 11 is fixedly installed with a ring sleeve 12, the ring sleeve 12 is a cylindrical structure, the ring sleeve 12 is inserted into the main core 2, and a fixing ring 6 is installed on the top of the ring sleeve 12, and the fixing ring 6 remains fixed. Figure 2The bottom of the bottom plate 33 is inserted into the fixing ring 6, and the fixing ring 6 is provided with a through hole 3 61. The lower end of the through hole 2 51 is connected to the through hole 3 61, and the through hole 3 61 passes through the fixing ring 6 from top to bottom to allow the iron oxide powder to flow from top to bottom.

[0035] like Figure 2 , Figure 4 , Figure 5 As shown, the outer wall of the protrusion 21 is installed with a shaft body 211, and multiple shaft bodies 211 are evenly distributed along the circumference of the outer wall of the protrusion 21. The shaft body 211 is rotatably connected with a rotating sleeve 212, and the rotating sleeve 212 is axially arranged along the radial direction of the protrusion 21, and the rotating sleeve 212 can rotate along its own axis.

[0036] like Figure 2 As shown, the fixing ring 6 is provided with an annular groove 62, which extends downward from the upper end of the fixing ring 6 and penetrates the inner wall of the fixing ring 6. The slip ring 7 is located in the annular groove 62 and can move up and down along the inner wall of the annular groove 62. The slip ring 7 is inserted with an insertion rod 71, which passes through the slip ring 7. The fixing ring 6 is also provided with a countersunk hole 63, the bottom of the insertion rod 71 is inserted into the countersunk hole 63 and can move up and down along the inner wall of the countersunk hole 63. The lower end surface of the insertion rod 71 abuts against a spring 72, which is located in the countersunk hole 63. A cover ring 64 is installed on the upper end of the fixing ring 6. The cover ring 64 is located above the insertion rod 71 and limits the insertion rod 71.

[0037] like Figure 2 As shown, a support rod 73 is installed on the inner wall of the slip ring 7. The support rod 73 can move up and down with the slip ring 7. The support rod 73 is evenly distributed along the circumference of the slip ring 7. The axial direction of the support rod 73 is arranged along the radial direction of the slip ring 7. The slip ring 7 is coaxially arranged with the protrusion 1 21. The rotating sleeve 212 and the support rod 73 are both located in the through hole 3 61. The bottom position of the rotating sleeve 212 can be lower than the top position of the support rod 73. When the rotating sleeve 212 rotates with the protrusion 1 21, it can abut against the support rod 73. Figure 7 In the initial state, the bottom position of the rotating sleeve 212 is lower than the top position of the support rod 73. When the rotating sleeve 212 rotates from the left position to the right position, the rotating sleeve 212 abuts against and presses down the support rod 73. At the same time, when the rotating sleeve 212 abuts against the support rod 73, since the support rod 73 is a fixed round rod, the rotating sleeve 212 rotates along its own axis, and the rotating path of the rotating sleeve 212 is along Figure 7 The outer circumferential surface of the upper end of the middle support rod 73 extends from P to Q. Since the iron oxide powder passing through the through hole 3 61 will fall to the upper end of the support rod 73, the agglomerated iron oxide powder will be crushed into fine particles by the rolling action of the rotating sleeve 212 on the support rod 73. At the same time, when the rotating sleeve 212 leaves the support rod 73, the support rod 73 continues to rise and bounce, generating vibration to shake off the iron oxide powder on the support rod 73.

[0038] like Figure 1 , Figure 2As shown, the upper end of the ring sleeve 12 is provided with a ring sleeve hole 121, and the through hole 3 61 is connected to the top of the ring sleeve hole 121. The ring sleeve hole 121 is a tapered hole with a large diameter at the upper end and a small diameter at the lower end. The lower end of the ring sleeve 12 is provided with a ring sleeve hole 2 122, and the ring sleeve hole 121 is connected with the ring sleeve hole 2 122 up and down. The inner wall surface of the ring sleeve hole 2 122 is a tapered surface, and the inner wall surface of the ring sleeve hole 2 122 matches the outer wall surface of the convex body 2 22. The inner wall surface of the ring sleeve hole 2 122 and the outer wall surface of the convex body 2 22 are arranged close to each other, and a gap is formed between the inner wall of the ring sleeve hole 2 122 and the outer wall of the convex body 2 22 to allow the iron oxide powder to flow, and the flow direction is from top to bottom and radially outward along the convex body 2 2.

[0039] like Figure 3 As shown, the inner wall surface of the ring hole 122 includes a protrusion 1221, and the protrusion 1221 is spiral. A groove portion 1222 is formed between the spiral lines of the protrusion 1221. The iron oxide powder enters the outer wall of the convex body 22 from the ring hole 121. The groove portion 1222 is used to form a bearing cavity for the circulation of the iron oxide powder. When the convex body 22 rotates, the protrusion 1221 and the outer wall of the convex body 22 further crush the iron oxide powder, thereby reducing agglomeration to facilitate subsequent mixing with the solvent.

[0040] like Figure 1 As shown, a plurality of extension rods 23 are installed on the outer wall of the lower part of the main core 2. The extension rods 23 are evenly distributed along the circumference of the main core 2 and are distributed in multiple layers up and down. The extension rods 23 are located below the guide hole 111 and the ring sleeve 12. After the iron oxide powder flows out from the bottom edge of the convex body 22, it mixes with the color paste solvent flowing out of the guide hole 111, and is fully mixed under the stirring action of the rotation of the extension rods 23, and finally passes out from the bottom of the mixing barrel 1.

[0041] A color paste mixing process, using the above color paste mixing device, the mixing process is as follows:

[0042] ① The main core 2 rotates under the drive of the motor 8, and at the same time drives the flow guide component 3 to rotate, and the color paste solvent and iron oxide powder are respectively added into the feed port 1 31 and the feed port 2 32;

[0043] ②Combination Figure 1 , Figure 2 The iron oxide powder passes through the through hole 2 51 of the distribution plate 5 and is put into the through hole 3 61 along the circumference of the fixing ring 6. The iron oxide powder entering the through hole 3 61 is impacted by the rotating sleeve 212 rotating with the convex body 21 to reduce the agglomerated iron oxide powder. At the same time, part of the iron oxide powder entering the through hole 3 61 is sprinkled on the upper end of the support rod 73. When the rotating sleeve 212 rotates with the convex body 21, it abuts against the support rod 73 and rotates, so that the rotating sleeve 212 rolls on the upper end of the support rod 73. The rotating sleeve 212 has a crushing effect on the iron oxide powder on the upper end of the support rod 73, further reducing the agglomerated iron oxide powder.

[0044] ③ The iron oxide powder passing through the through hole 3 61 enters the outer wall of the convex body 22 along the ring hole 121 and is transported along the outer wall of the convex body 22. As the convex body 22 rotates, the convex body 22 and the protrusion 1221 rotate relative to each other, and the convex body 22 and the protrusion 1221 further crush the iron oxide between them. Since the protrusion 1221 is spiral-shaped and the outer wall of the convex body 22 gradually tilts downward from top to bottom, the iron oxide powder is gradually transported downward along the outer wall of the convex body 22 and leaves the convex body 22 more smoothly.

[0045] ④ The iron oxide powder leaving the second protrusion 22 is transported downward along the channel between the outer wall of the second protrusion 22 and the inner wall of the mixing barrel 1. At the same time, the color paste solvent injected from the feed port 1 31 also flows into the channel between the outer wall of the second protrusion 22 and the inner wall of the mixing barrel 1 along the guide tube 4 and the support ring 11. The color paste solvent and the iron oxide powder are fully mixed under the stirring of the extension rod 23 to form a color paste. After mixing, the color paste passes out from the bottom of the mixing barrel 1.

[0046] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
