Detailed implementation manners

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0033] As Figures 1 to 3 shown, a coloring component for a mixer includes a coloring tank 1 and a spray ring pipe 10 suspended at the inner top of the coloring tank 1. A pigment supply part 16 for continuously supplying pigment to the spray ring pipe 10 is provided at the top of the coloring tank 1. The pigment supply part 16 includes a supply pump provided at the top of the coloring tank 1 and a feed hopper provided at the top of the coloring tank 1. The feed hopper and the supply pump, and the supply pump and the spray ring pipe are communicated through conduits. The coloring component for the mixer further includes:

[0034] A support base 12 fixed to the inner bottom of the coloring tank 1.

[0035] A main sleeve shaft 2 rotatably provided between the top of the coloring tank 1 and the top of the support base 12, and a transmission cavity 3 is provided inside the main sleeve shaft 2.

[0036] A plurality of horizontal shafts 4 rotatably provided horizontally on the main sleeve shaft 2.

[0037] A transmission part 6 for linking the main sleeve shaft 2 and the horizontal shafts 4.

[0038] Turning pieces 5 relatively fixed on the horizontal shafts 4, and the surface of the turning pieces 5 can be a straight surface or a micro-curved surface to facilitate turning the ingredients up and down, so as to increase the probability and uniformity of collision coloring between the ingredients.

[0039] A plurality of turning shovels 7 fixed to the main sleeve shaft 2.

[0040] A support frame 11 fixed to the top of the coloring tank 1.

[0041] A driving part 15 arranged on the support frame 11 for driving the main sleeve shaft 2 to rotate. The driving part 15 includes a driving motor arranged on the support frame 11. A transmission gear is fixedly arranged at the output end of the driving motor. A spur gear is arranged at the top end of the main sleeve shaft 2. The transmission gear meshes with the spur gear. By starting the driving motor, through the power transmission of the transmission gear and the spur gear, the driving of the main sleeve shaft 2 to rotate can be realized, so that it drives the cross shaft 4 and the turning shovel 7 to revolve circumferentially synchronously. And while the cross shaft 4 is revolving, a relative rotation is formed between the helical gear 62 at one end of the cross shaft 4 and the helical gear 62 on the vertical shaft 61, realizing the self-rotation of the cross shaft 4, thereby driving the turning blade 5 to rotate synchronously, realizing the batching and stir-frying in the circumferential and up-and-down directions, and improving the uniformity and efficiency of batching coloring.

[0042] In this embodiment, the coloring component for the mixer further includes:

[0043] A screen 8 fixed between the support base 12 and the inner wall of the coloring tank 1. The screen 8 and the bottom of the inner wall of the coloring tank 1 enclose a reflux cavity 9.

[0044] A confluence trough 13 horizontally arranged at the bottom of the support base 12.

[0045] A collecting pipe 14 for connecting the confluence trough 13 and the outside of the coloring tank 1. A solenoid valve is arranged on the collecting pipe 14 to facilitate accurate and efficient control of the on-off of the collecting pipe 14.

[0046] Through the combined use of the turning blade 5 and the turning shovel 7, the stir-frying of the skin batching is realized from multiple directions, improving the efficiency and uniformity of batching coloring, and being able to turn the batching greatly, so that the redundant pigments on its surface can seep down efficiently, improving the recovery efficiency of redundant pigments and the utilization efficiency of pigments.

[0047] In this embodiment, the transmission member 6 includes:

[0048] A vertical shaft 61 fixedly inserted into the transmission cavity 3.

[0049] Several helical gears 62 fixed on the vertical shaft 61 and a helical gear 62 fixed at one end of the cross shaft 4.

[0050] The tooth surfaces of two adjacent helical gears 62 mesh with each other, and the cross shaft 4 is relatively distributed on the main sleeve shaft 2.

[0051] When the main sleeve shaft 2 drives the cross shaft 4 to revolve synchronously, a relative rotation is formed between the helical gear 62 at one end of the cross shaft 4 and the helical gear 62 on the vertical shaft 61, thereby realizing the self-rotation of the driving cross shaft 4, thus realizing three-dimensional multi-directional turning of the batching, enabling it to be colored efficiently and uniformly, and also being able to efficiently recycle the redundant pigments, improving the recycling utilization rate of pigments.

[0052] In this embodiment, the top and bottom ends of the vertical shaft 61 pass through the top and bottom of the main sleeve shaft 2 respectively, and the top and bottom ends of the vertical shaft 61 are fixed to the support frame 11 and the support base 12 respectively. With such a design, relative rotation can occur between the helical gear 62 at one end of the horizontal shaft 4 and the helical gear 62 on the vertical shaft 61, thereby realizing the self-rotation of the horizontal shaft 4, increasing the number of directions for flipping and mixing the ingredients, and improving the coloring efficiency of the ingredients.

[0053] In this embodiment, the horizontal shaft 4 and the material turning shovel 7 are staggered along the axial direction of the main sleeve shaft 2, and the horizontal shaft 4 and the material turning shovel 7 are also staggered in the circumferential direction. With such a design, the degree of mutual interference between various components when stir-frying the ingredients can be minimized, thereby improving the efficiency and uniformity of ingredient coloring. It can also achieve the improvement of the recovery efficiency of excess pigment by flipping the ingredients significantly, achieving multiple benefits at once.

[0054] Working principle: When the ingredients (the ingredients are granular solid materials) are transported into the coloring tank 1 through the pipeline, the driving part 15 and the pigment supply part 16 can be started synchronously. The pigment supply part 16 supplies materials to the spray ring pipe 10 and sprays the materials in a ring shape onto the ingredients entering the coloring tank 1 through the spray ring pipe 10. And the driving part 15 directly drives the main sleeve shaft 2 to rotate. The main sleeve shaft 2 drives the material turning shovel 7 and the horizontal shaft 4 to revolve synchronously in the circumferential direction, so that a relative circumferential rotation is formed between the helical gear 62 at the end of the horizontal shaft 4 and the helical gear 62 on the vertical shaft 61. And the helical gear 62 at the end of the horizontal shaft 4 meshes with the helical gear 62 on the vertical shaft 61, realizing the self-rotation of the horizontal shaft 4 and driving the turning blade 5 to rotate synchronously. It can not only realize stir-frying the ingredients in the circumferential direction, but also realize stir-frying the ingredients up and down in the circumferential direction, increasing the mixing uniformity between the ingredients and increasing the contact probability between the pigment and the ingredients, thereby improving the efficiency and uniformity of ingredient coloring. And when the ingredients are stir-fried significantly, the excess pigment on the surface of the ingredients can quickly contact or infiltrate into other ingredients until it flows into the return cavity 9, realizing the efficient recovery of excess pigment.

[0055] The above is only the preferred embodiment of the present invention, and the parts not described in the present invention can be realized by adopting or referring to the existing technology. Of course, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also belong to the protection scope of the present invention.
