Description

Technical Field

[0001] This utility model relates to the field of color paste mixing technology, specifically to a color paste mixing machine. Background Technology

[0002] Color mixing involves precisely blending different colors and proportions of color pastes to achieve the desired color. It is widely used in industries such as coatings, printing, textiles, and plastics.

[0003] Traditional pigment mixing involves feeding different pigments into a mixing tank in equal proportions and then stirring the pigments using a motor-driven stirring shaft to obtain the appropriate pigment. This method of pigment production is time-consuming not only in terms of feeding but also in subsequent stirring and pigment discharge. Furthermore, the mixing tank cannot continue to produce the required pigment until all the pigment in the batch has been discharged. In other words, this batch-based pigment production method is time-consuming and has high time costs for pigment mixing. Therefore, a pigment mixing machine is proposed to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above description, this utility model provides a color paste mixing machine to solve the problem of high time cost when using existing color paste mixing machines.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A color paste mixing machine, comprising: a feeding pipe and a pipe stirring mechanism;

[0006] The pipeline stirring mechanism includes a hollow shell. A motor with an output shaft extending into the interior of the hollow shell is provided on the outer surface of the hollow shell. A drive gear located inside the hollow shell is provided at the output shaft of the motor. A toothed stirring tube meshing with the drive gear is provided inside the hollow shell. A feed pipe and a connecting pipe located on the axial extension line of the toothed stirring tube are respectively provided at both ends of the hollow shell. The feed pipe, the connecting pipe and the toothed stirring tube are interconnected.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the feed pipe includes a main pipe, and a plurality of branch pipes are provided at one end of the main pipe away from the hollow shell, and the plurality of branch pipes are interconnected with the main pipe.

[0009] Furthermore, the hollow outer shell includes two semi-shells, and each of the two semi-shells is provided with a connecting pipe on its opposite side, which is connected to the semi-shell. The two connecting pipes are respectively connected to the feed pipe and the connecting pipe.

[0010] Furthermore, each of the two half-shells has a transmission cavity and a movable cavity that are interconnected on opposite sides. The movable cavity is interconnected with the connecting pipe and has an inner diameter larger than that of the connecting pipe. A limit groove is provided on the inner wall of the movable cavity facing the connecting pipe.

[0011] Furthermore, a motor is provided on the outer surface of the semi-shell, and the output shaft of the motor extends into the interior of the transmission cavity, where a drive gear connected to the output shaft of the motor is provided.

[0012] Furthermore, the toothed stirring tube includes a rotating tube disposed inside the movable cavity. An annular groove is provided on the circumferential surface of the rotating tube, and a toothed surface is provided inside the annular groove. The toothed surface meshes with the driving gear.

[0013] Furthermore, the two ends of the rotating tube are provided with limiting cylinders extending into the limiting groove. The circumferential surface of the limiting cylinder is provided with multiple mounting through holes. The inside of the mounting through holes is provided with ball bearings extending to the outside of the mounting through holes and in contact with the inner wall of the limiting groove. The inner diameter of the limiting cylinder is larger than the inner diameter of the rotating tube.

[0014] Furthermore, a stirring element is provided on the circumferential surface inside the rotating tube. The stirring element includes a hollow auger, multiple inclined plates, and multiple stirring rods.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] 1. This utility model, by setting up components such as a feed pipe and a pipe stirring mechanism, allows different color pastes to enter the pipe stirring mechanism simultaneously through the feed pipe. During the color paste transportation process, the toothed stirring pipe is driven to rotate by a motor and a drive gear. The stirring component rotates together with the toothed stirring pipe, thereby stirring the color paste inside the rotating pipe. This achieves the effect of continuous pigment production by stirring the color paste during transportation inside the pipe.

[0017] 2. By designing the hollow auger, inclined plate, and stirring rod, different stirring capacities are achieved. This allows for different stirring capacities to be obtained by replacing different toothed stirring tubes when facing different practical needs, thus increasing the practicality of the device.

[0028] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0030] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0031] Please see Figures 1-3 A color paste mixing machine includes: a feed pipe 1 and a pipe mixing mechanism;

[0032] The feed pipe 1 includes a main pipe 11. The end of the main pipe 11 away from the hollow shell 2 is provided with multiple branch pipes 12. The multiple branch pipes 12 are interconnected with the main pipe 11. The end of the branch pipe 12 away from the main pipe 11 is interconnected with the pigment storage tank through a pressure pump and a pipe. A regulating valve is provided between the branch pipe 12 and the pressure pump. The regulating valve is used to regulate the amount of pigment raw material entering the branch pipe 12. The pressure pump is used to deliver the pigment so that the pigment can enter the interior of the branch pipe 12.

[0033] Based on the above, the branch pipe 12 and the main pipe 11 cooperate with each other so that different color pastes can enter the interior of the main pipe 11 through the branch pipe 12 at the same time, and the amount of color paste entering is controlled by the regulating valve, thereby achieving the effect of controlling the mixing ratio.

[0034] like Figure 2 and Figure 8 As shown, the pipe stirring mechanism includes a hollow shell 2. A motor 4 with an output shaft extending into the interior of the hollow shell 2 is provided on the outer surface of the hollow shell 2. A drive gear 5 located inside the hollow shell 2 is provided at the output shaft of the motor 4. A toothed stirring tube 6 that meshes with the drive gear 5 is provided inside the hollow shell 2. A feed pipe 1 and a connecting pipe 3 located on the axial extension line of the toothed stirring tube 6 are respectively provided at both ends of the hollow shell 2. The feed pipe 1, the connecting pipe 3 and the toothed stirring tube 6 are interconnected.

[0035] like Figure 4 and Figure 5 As shown, the hollow outer shell 2 includes two half-shells 21. Each of the two half-shells 21 has a connecting pipe 22 that communicates with each other on opposite sides. The two connecting pipes 22 are respectively connected to the feed pipe 1 and the connecting pipe 3. A sealing ring is provided between the two half-shells 21. Sealing rings are also provided between the connecting pipe 22 and the feed pipe 1 and between the connecting pipe 22 and the connecting pipe 3.

[0036] Each of the two half-shells 21 has a transmission cavity 23 and a movable cavity 24 that are interconnected on opposite sides. The movable cavity 24 is interconnected with the connecting pipe 22 and has an inner diameter larger than that of the connecting pipe 22. A limiting groove 25 is provided on the inner wall of the movable cavity 24 facing the connecting pipe 22. Two rotating sealing rings are provided inside the movable cavity 24. The inner rings of the two rotating sealing rings are tightly fitted to the outer circumferential surfaces of both ends of the toothed stirring tube 6.

[0037] The outer surface of the semi-shell 21 is provided with a motor 4, the output shaft of the motor 4 extends into the interior of the transmission cavity 23, and the interior of the transmission cavity 23 is provided with a drive gear 5 connected to the output shaft of the motor 4;

[0038] Based on the above, the two half-shells 21 are connected to each other to form a complete shell. The transmission cavity 23 provides space for the rotation of the drive gear 5, and the movable cavity 24 provides space for the rotation of the toothed stirring tube 6. The motor 4 is preferably a servo motor of model LH130100AP. When the motor 4 is powered on, it drives the drive gear 5 to rotate. Under the action of gear transmission, it drives the toothed stirring tube 6 to rotate, thereby stirring the pigment flowing through the toothed stirring tube 6.

[0039] like Figure 6 As shown, the toothed stirring tube 6 includes a rotating tube 61 disposed inside the movable cavity 24. An annular groove 62 is provided on the circumferential surface of the rotating tube 61, and a toothed surface 63 is provided inside the annular groove 62. The toothed surface 63 meshes with the driving gear 5.

[0040] The two ends of the rotating tube 61 are provided with limiting cylinders 64 extending into the limiting groove 25. The circumferential surface of the limiting cylinder 64 is provided with a plurality of mounting through holes 65. The inside of the mounting through holes 65 is provided with ball bearings 66 extending to the outside of the mounting through holes 65 and contacting the inner wall of the limiting groove 25. The inner diameter of the limiting cylinder 64 is larger than the inner diameter of the rotating tube 61. The circumferential surface inside the rotating tube 61 is provided with a stirring element 67.

[0041] Based on the above, the toothed surface 63 enables the toothed stirring tube 6 to mesh with the drive gear 5 and rotate under the action of gear transmission. When the toothed stirring tube 6 rotates, the stirring element 67 rotates together, thereby stirring the mixed pigment flowing through the rotating tube 61.

[0042] By setting the limiting cylinder 64 and the ball bearing 66, on the one hand, they cooperate with the limiting groove 25 to limit the toothed stirring tube 6, and on the other hand, the ball bearing 6 makes the rotation of the self-rotating tube 61 smoother and reduces the resistance of friction.

[0043] like Figure 7As shown, the stirring component 67 includes a hollow auger 671, multiple inclined plates 672 and multiple stirring rods 673. The multiple inclined plates 672 are distributed in a ring at equal intervals along the inner wall of the rotating tube 61, and the multiple stirring rods 673 are distributed in a ring at equal intervals along the inner wall of the rotating tube 61.

[0044] Based on the above, the agitator 67 is designed to agitate the pigment paste. The arrangement of the hollow auger 671, the inclined plate 672, and the agitator 673 gives the toothed agitator 6 different agitation capabilities. The agitator 673 has the best agitation effect, but it only uses a pressure pump to transport the pigment paste, resulting in a weak transport capacity. The inclined plate 672 has relatively strong agitation and transport capabilities, while the hollow auger 671 has a strong transport capacity but a relatively weak agitation capacity.

[0045] In summary, this color paste mixing machine works in conjunction with a pressure pump and a regulating valve. When the color paste in the color paste storage tank is fed into the feed pipe 1 under the action of the pressure pump, color pastes of different colors come into contact with each other to form a preliminary mixed color paste. After the mixed color paste is delivered into the rotating pipe 61, the motor 4 drives the drive gear 5 to drive the toothed stirring pipe 6 to rotate, thereby realizing the secondary mixing of the preliminary mixed color paste.

[0046] This color mixing machine replaces the traditional mixing tank by stirring and mixing the color paste during pipeline transportation, thereby achieving continuous output and effectively reducing time costs.

[0047] Furthermore, multiple pipe mixing mechanisms are connected in series to achieve a better mixing effect. In addition to adjusting the feed rate by regulating the valve, the feed rate can also be adjusted by changing the inner diameter of the branch pipe. By setting branch pipes 12 with different diameters, the ratio of different color pastes is kept constant, that is, the proportion of color paste entering the main pipe 11 is kept constant, thereby ensuring a constant ratio.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
