[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0047] Reference Figure 1-Figure 5 A construction paint ingredient grinding device includes an inner ring body 2 rotating in a shell 1. In some embodiments, the inner cavity of the shell 1 is a cylindrical structure with both ends closed, and the outer wall of the inner ring body 2 rotates in contact with the inner wall of the inner cavity of the shell 1. To ensure sealing, a sealing ring is provided on the outer wall of the inner ring body 2.

[0048] It should be added that the driving structure for the rotation of the inner ring body 2 is the prior art. For example, an inner ring driving gear ring is provided on the outer wall of the inner ring body 2, a driving motor is fixed on the shell 1, and an inner ring driving gear for driving the inner ring driving gear ring is provided on the output end of the driving motor. The inner ring body 2 is driven to rotate by the driving motor. The method of driving the inner ring body 2 to rotate is not the focus of protection of this application document. Any structure that can drive the inner ring body 2 to rotate is acceptable, and this is not described in detail.

[0049] Reference Figure 1 The outer wall of the shell 1 is horizontally provided with a plurality of feed ports 10, and the plurality of feed ports 10 are arranged equidistantly for the inflow of different coating raw material components.

[0050] Reference Figure 2 The inner ring body 2 is provided with a plurality of paint grinding chambers 20 arranged horizontally along the inner ring body 2. Preferably, the number of the paint grinding chambers 20 is at least equal to the number of the feed ports 10, so as to ensure that each paint raw material component is ground in its respective paint grinding chamber 20.

[0051] Based on the setting of the feed port 10, in order to facilitate the flow of raw materials into the paint grinding chamber 20, an inlet 200 is set on the inner wall of the paint grinding chamber 20, and the inlets 200 on different paint grinding chambers 20 correspond to different feed ports 10 in turn. Specifically, the inlets 200 on different paint grinding chambers 20 are staggered and located at different levels.

[0052] In addition, the inner wall of the paint grinding chamber 20 is also provided with an outlet 201 for discharging the paint raw materials after grinding in the paint grinding chamber 20 .

[0053] Based on the setting of the paint grinding chamber 20, in some embodiments, a rotating grinding frame 4 is provided in the paint grinding chamber 20 to grind the paint raw materials. Further, the grinding frame 4 is a cylindrical cavity structure, and its two ends are closed, and the outer wall of the grinding frame 4 is only provided with an inlet and outlet 40, that is, the paint raw materials enter the grinding frame 4 from the inlet and outlet 40, and also flow out of the grinding frame 4 from the inlet and outlet 40. It should be noted that: the two ends of the paint grinding chamber 20 are equal in length to the inner ring body 2, that is, the paint grinding chamber 20 is set with openings at both ends. In addition, in order to ensure sealing, the outer wall of the grinding frame 4 is also provided with a sealing layer structure, and the sealing layer is preferably a rubber layer.

[0054] Based on the setting of the grinding frame 4, the present embodiment further discloses a structure for driving the grinding frame 4 to rotate, so as to facilitate the grinding of the coating raw material. The specific setting is as follows: a driving ring 41 is arranged on the outer wall of the end of the grinding frame 4, wherein the outer diameter of the driving ring 41 is smaller than the outer diameter of the grinding frame 4, a grinding frame driving gear 42 is sleeved on the outer wall of the driving ring 41, and a grinding frame driving gear ring 43 meshing with the grinding frame driving gear 42 is arranged on the inner wall of the housing 1. Figure 3 Preferably, the grinding frame driving gear ring 43 is arranged on the outer wall of the grinding frame driving gear 42. When the inner ring body 2 rotates, the grinding frame 4 rotates following the inner ring body 2. The grinding frame 4 rotates through the cooperation of the grinding frame driving gear 42 and the grinding frame driving gear ring 43.

[0055] Based on the setting of the grinding frame 4 , this embodiment further discloses a composition of a grinding component inside the grinding frame 4 , which is composed of a central shaft 44 and a grinding roller 45 , and the grinding of the coating raw material is achieved through the grinding roller 45 .

[0056] Reference Figure 4 , the central shaft 44 is arranged in the grinding frame 4, wherein the central shaft 44 includes an inner shaft body 440 and an outer shaft sleeve 441, wherein the outer shaft sleeve 441 is arranged outside the inner shaft body 440, and an intermittent passage is formed between the inner shaft body 440 and the outer shaft sleeve 441. It should be noted that one end of the inner shaft body 440 is fixed to the inner end surface of the cylindrical cavity in the grinding frame 4, while the other end is not fixed. The outer shaft sleeve 441 is provided with an inner shaft body groove for accommodating the inner shaft body 440, wherein the inner diameter of the notch position is the same as the outer diameter of the inner shaft body 440, and an intermittent passage is formed between the inner shaft body 440 and the outer shaft sleeve 441 at other locations.

[0057] Reference Figure 4 A plurality of grinding roller groups are radially extended outward from the outer wall of the central axis 44 , wherein the grinding roller groups are equidistantly distributed circumferentially along the outer wall of the central axis 44 , and each grinding roller group is composed of a plurality of grinding rollers 45 distributed horizontally along the central axis 44 , and the coating raw materials are ground between adjacent grinding rollers 45 .

[0058] Further, see Figure 4 The specific setting position of the grinding roller 45 is as follows: one end of the grinding roller 45 passes through the outer sleeve 441 and extends to the inner shaft body 440 until it is located in the intermittent channel between the inner shaft body 440 and the outer sleeve 441. The end of the grinding roller 45 extending into the intermittent channel is provided with a grinding roller gear 450, and two adjacent grinding roller gears 450 are meshed with each other. With this arrangement, after one grinding roller gear 450 in the same grinding roller group is driven to rotate, all the grinding rollers 45 in the same group can be synchronously actuated, and the arrangement of this grinding roller gear 450 just causes the adjacent grinding roller gears 450 to rotate in opposite directions, and then causes the adjacent grinding rollers 45 to rotate in opposite directions, thereby helping to achieve sufficient grinding of the coating raw materials from between the two grinding rollers 45.

[0059] Further, refer to Figure 4The present embodiment also discloses a structure for driving one of the grinding roller gears 450 of the same grinding roller group to rotate, which is specifically configured as follows: an inner shaft gear ring 445 is disposed on the outer wall of the inner shaft body 440, wherein a grinding roller 45 located at the end is provided with a grinding roller driving gear 451 meshing with the inner shaft gear ring 445. Since the inner shaft body 440 is fixed to the inner wall of the grinding frame 4, when the outer shaft sleeve 441 rotates, the inner shaft gear ring 445 cooperates with the grinding roller driving gear 451, causing the grinding roller driving gear 451 to rotate, thereby driving multiple grinding rollers 45 of the same group to rotate, so as to complete the grinding process of the coating raw materials.

[0060] In addition, this embodiment also discloses a structure for driving the outer sleeve 441 to rotate, which is realized when the inner ring body 2 rotates, and the structure is the same as the rotation structure of the grinding frame 4, and is composed of an outer sleeve gear 443 and an outer sleeve driving gear ring 444.

[0061] Reference Figure 3 and Figure 4 An outer sleeve shaft 442 is fixed to one end of the outer sleeve 441 away from the inner shaft body 440, and one end of the outer sleeve shaft 442 passes through the grinding frame 4 and the inner ring body 2 in sequence and is fixed with an outer sleeve gear 443. The inner wall of the inner cavity of the shell 1 is provided with an outer sleeve driving gear ring 444 that meshes with the outer sleeve gear 443. Preferably, the outer sleeve driving gear ring 444 is located on the outside of the outer sleeve gear 443, which is the same as the grinding frame driving gear ring 43 that is set on the outside of the grinding frame driving gear 42. When the inner ring body 2 rotates, the grinding frame 4 and the outer sleeve 441 have the same rotation direction, but due to the different sizes of the grinding frame driving gear ring 43 and the outer sleeve driving gear ring 444, the rotation speeds of the grinding frame 4 and the outer sleeve 441 are different.

[0062] It should be added that: in order to facilitate the installation of the grinding frame driving gear ring 43 and the outer sleeve driving gear ring 444, the grinding frame driving gear ring 43 and the outer sleeve driving gear ring 444 are staggered. Furthermore, the distance between the outer sleeve gear 443 and the inner wall of the inner cavity of the shell 1 is smaller than the distance between the grinding frame driving gear 42 and the inner wall of the inner cavity of the shell 1, so that the meshing movement of the outer sleeve gear 443 and the meshing movement of the grinding frame driving gear 42 do not interfere with each other.

[0063] In addition, refer to Figure 2The inner wall of the inner cavity of the grinding frame 4 is provided with a plurality of inclined guide protrusions 46 at equal intervals in a circular shape, wherein the guide protrusions 46 rotate with the rotation of the grinding frame 4, and the rotation of the guide protrusions 46 drives the coating raw materials at the bottom of the grinding frame 4 to be transferred, that is, as the grinding frame 4 rotates, the coating raw materials taken away by the angle between the guide protrusions 46 and the grinding frame 4 rotate to the top, and then the coating raw materials fall down, and the fallen coating raw materials fall between the two grinding roller groups on the outer wall of the central shaft 44, wherein the cross section between the two grinding roller groups forms a V-shaped storage structure, causing the coating raw materials to be ground to stay, and further completing the grinding process. It should be supplemented that: the grinding frame 4 and the outer sleeve 441 rotate in the same direction but at different speeds, which ensures that the coating raw materials are in the V-shaped storage structure for a certain time, and further the coating raw materials can be fully ground.

[0064] Reference Figure 2 A mixing chamber 3 is provided in the inner ring body 2, and all the ground raw materials can be further mixed, and the mixing chamber 3 provides space for mixing the raw materials.

[0065] Reference Figure 2 A mixing tank 6 is fixed in the mixing chamber 3 , wherein the mixing tank 6 is a wall structure containing a cavity, and one end of the mixing tank 6 is fixed to the inner wall of the inner cavity of the shell 1 and does not rotate with the inner ring body 2 .

[0066] In addition, in order to facilitate the grinding of each paint raw material into the inner cavity of the mixing tank 6, the outer wall of the mixing tank 6 is provided with a strip-shaped discharge port corresponding to the position of the outlet 201, wherein the outlet 201 provided on the inner wall of the paint grinding chamber 20 can be aligned with the discharge port.

[0067] Furthermore, one end of the mixing tank 6 is closed and the other end is open, and the opening end of the mixing tank 6 is connected to the shell 1. The shell 1 is provided with a mixing tank door 7 for opening the opening end of the mixing tank 6. The mixing tank door 7 is opened and closed to realize the discharge of the mixed paint raw materials in the mixing tank 6. Specifically, the mixing tank door 7 is an openable and closable disc-shaped door structure, which is not the focus of protection of the present application document, and any openable or closed door structure is acceptable.

[0068] Finally, a mixing assembly is also provided in the mixing tank 6, see Figure 5, wherein the mixing assembly is a concentric shaft and mixing blades rotating in the mixing tank 6. A gap is left between the closed end of the mixing tank 6 and the outer wall of the inner ring body 2, and a transmission shaft is fixed to the closed end of the mixing tank 6, and the transmission shaft and the outer wall of the concentric shaft are both fixed with mutually meshing mixing gears, and a mixing gear ring is provided on the inner wall of the mixing chamber 3, wherein the mixing gear ring meshes with the mixing gear connected to the outer wall of the transmission shaft, rotates with the inner ring body 2, actuates the mixing gear ring to rotate, and thereby actuates the coaxial shaft to rotate through the transmission of the two mixing gears. The mixing blade is a U-shaped rod fixed on the outer wall of the concentric shaft, wherein the two ends of the U-shaped rod are fixed on the outer wall of the concentric shaft, and the outer wall of the horizontal end of the U-shaped rod fits the inner wall of the cylindrical cavity of the mixing tank 6; in addition, a symmetrically distributed inclined mixing guide plate 5 is provided on one side of the U-shaped rod close to the concentric shaft, and the inclined mixing guide plate 5 is provided, when the concentric shaft rotates in the forward direction, after the inclined mixing guide plate 5 takes up the paint at the bottom, the paint slides downward along the inclined surface of the inclined mixing guide plate 5 surface, and the paint aggregates toward the center of the mixing tank 6; on the contrary, when the concentric shaft rotates in the reverse direction, after the inclined mixing guide plate 5 takes up the paint at the bottom, the paint slides downward along the inclined surface of the inclined mixing guide plate 5 surface, and the paint disperses toward both sides of the mixing tank 6. Therefore, during the process of mixing the paint, the positive and negative rotation of the inner ring body 2 can drive the paint in the mixing tank 6 to alternately aggregate inward and disperse outward, and the mixing of the paint raw materials is achieved through this process; further, after the paint leaves the inclined mixing guide plate 5, it falls on the top of the bottom paint in a scattered manner, which helps to separate the paint and facilitate mixing.

[0069] The method for using the architectural coating ingredient grinding device is as follows: comprising the following steps:

[0070] S1, distributing materials into feed ports: distributing different coating raw materials into different feed ports 10;

[0071] S2, grinding: the inner ring body 2 rotates, and when the inlet and outlet 40 on the grinding frame 4 is aligned with the feed port 10, the coating material in the feed port 10 enters the grinding frame 4 through the inlet 200;

[0072] The grinding frame 4 rotates, and guides the coating material from the bottom into the V-shaped structure between two adjacent grinding roller groups through the material guide protrusion 46;

[0073] Through the cooperation of the outer sleeve gear 443 and the outer sleeve driving gear ring 444, the adjacent grinding rollers 45 in each grinding roller group are actuated to rotate, thereby grinding the coating raw material;

[0074] S3, the ground coating material is introduced into the mixing tank 6; as the inner ring body 2 rotates, when the inlet and outlet 40, the outlet 201 and the feed port are aligned, the ground coating material flows into the mixing tank 6;
