Description

TECHNICAL FIELD

[0001] The utility model relates to paint production technical field, concretely relates to a kind of colour mixing devices for paint production. BACKGROUND

[0002] Paint generally refers to all liquid components in color paint, is the semi-finished product for preparing paint, and the main components include base material, solvent and additive. After being coated on the surface of an object using different coating processes, the paint forms a tough and continuous film on the surface of the object.

[0003] Patent No. 202022554090.2 discloses a color mixing device for paint production. This device can produce different colors of paint in each mixing cavity, meeting the requirement of producing multiple colors of paint at one time and greatly shortening the production cycle.

[0004] However, the existing color mixing device for paint production uses a stirring shaft and stirring blades to mix paint, and after the color mixing is completed, a discharge control mechanism is used to discharge the paint. However, when the paint is discharged, some of it will adhere to the inner wall of the mixing cavity, making it difficult to be discharged, resulting in waste of resources. In addition, when the concentration of paint in the mixing cavity is too high, the paint is discharged slowly, affecting the processing efficiency of the paint. Therefore, a color mixing device for paint production is needed. UTILITY MODEL CONTENTS

[0005] To solve the problems in the background art, the utility model provides a color mixing device for paint production.

[0006] The utility model solves the technical problems by adopting a color mixing device for paint production, which includes a cylinder. The cylinder is internally provided with a cavity for color mixing. A bracket is bolted to the top of the cylinder, and an electric motor is bolted to the outside of the bracket. A power output flange of the electric motor is connected to a reducer, and a driving rod is keyed to the inside of the reducer. A stirring rod A and a stirring rod B are symmetrically screwed to the outside of the driving rod. A square plate is screwed to the outside of the stirring rod B to scrape the inner wall of the cavity. A bearing is screwed to the inside of the cylinder to stabilize the rotation of the driving rod. Rubber blocks A and B are symmetrically embedded in the inside of the cylinder to seal the bearing. A branch pipe is inserted into the outside of the cylinder. A discharge pipe is inserted into one side of the cylinder to discharge the color-mixed paint. A valve is provided on the outside of the discharge pipe. A spring is welded inside the discharge pipe. An arc-shaped block is welded to one end of the spring, and the end of the arc-shaped block away from the spring extends into the cavity.

[0007] By adopting the above technical solution, the external pipeline for conveying paint is first connected to the branch pipe outside the cylinder. Then, the paint that needs to be colored is conveyed into the cavity inside the cylinder. There are three sets of cavities inside the cylinder. Then, the motor on the bracket drives the reducer to rotate through the PLC controller. The external stirring rods A and B of the driving rod stir and mix the paint in the cavity. The driving rod extends to the three cavities through the bearing inside the cylinder, and stirs the paint in the three cavities simultaneously. The rubber blocks A and B outside the bearing seal the bearing. After the paint is mixed, the valve on the discharge pipe is opened to allow the paint to be discharged from the discharge pipe.

[0008] When the paint is discharged from the discharge pipe, the drive rod drives the stirring rod A and stirring rod B to rotate. Then, stirring rod B drives the external square plate to rotate, and the square plate scrapes the inner wall of the cavity, which facilitates the cleaning of the paint adhering to the cavity and improves the utilization rate of the paint.

[0009] When the square plate rotates to one side of the discharge pipe, it presses against the arc-shaped block inside the discharge pipe. The arc-shaped block then retracts and enters the discharge pipe, and the spring at one end of the arc-shaped block is compressed. When the square plate moves away from the discharge pipe, the spring causes the arc-shaped block to pop outward, thereby generating suction in the discharge pipe and improving the conveying efficiency of the paint.

[0010] Specifically, a scraper is welded to the outside of the stirring rod A to scrape the rubber block A.

[0011] By adopting the above technical solution, when the stirring rod A adjusts the color of the paint in the cavity, the scraper on the stirring block A scrapes the rubber block A, and multiple sets of stirring rods A are set outside the drive rod. The scraper on another set of stirring rods A scrapes the rubber block B, which facilitates the cleaning of the paint on the rubber block A and the rubber block B.

[0012] Specifically, the spring is fitted with a rubber sleeve to protect it.

[0013] By adopting the above technical solution, a rubber sleeve is fixed to one side of the arc-shaped block with screws, and the rubber sleeve is located outside the spring, which facilitates the protection of the spring.

[0014] Specifically, the bottom of the cylinder is bolted to a base frame that supports the cylinder.

[0015] By adopting the above technical solution, the base frame at the bottom of the cylinder supports the cylinder, improving the stability of the cylinder.

[0016] Specifically, the input terminals of both the motor and the reducer are electrically connected to the power supply terminal of an external power source.

[0017] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0018] The beneficial effects of this utility model are:

[0019] (1) The color matching device for paint production described in this utility model, when the paint is discharged from the discharge pipe, the drive rod drives the stirring rod A and stirring rod B to rotate, and then the stirring rod B drives the external square plate to rotate, and then the square plate scrapes the inner wall of the cavity, thereby facilitating the cleaning of the paint adhering to the cavity and improving the utilization rate of the paint.

[0020] (2) The color matching device for paint production described in this utility model, when the square plate rotates to one side of the discharge pipe, the square plate presses the arc block in the discharge pipe, and then the arc block retracts into the discharge pipe. The spring at one end of the arc block is compressed. When the square plate moves away from the discharge pipe, the spring drives the arc block to pop outward, thereby generating suction in the discharge pipe and improving the conveying efficiency of the paint.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] For the purpose of color matching of paint, as one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the present invention discloses a color-matching device for paint production, comprising a cylindrical body 6, inside which is a cavity 12 for color matching of paint. A bracket 9 is bolted to the top of the cylindrical body 6, and a motor 1 is bolted to the outside of the bracket 9. A reducer 2 is flanged to the power output end of the motor 1, and a drive rod 3 is keyed to the inside of the reducer 2. A stirring rod A10 and a stirring rod B13 are symmetrically screwed to the outside of the drive rod 3. A square scraping device for scraping the inner wall of the cavity 12 is screwed to the outside of the stirring rod B13. Plate 17, bearing 15 is fixed inside the cylinder 6 with screws to stabilize the rotation of the drive rod 3, rubber blocks A14 and B16 are symmetrically embedded inside the cylinder 6 to seal the bearing 15, branch pipe 7 is inserted outside the cylinder 6, discharge pipe 5 is inserted on one side of the cylinder 6 to discharge the tinted paint, valve 4 is provided outside the discharge pipe 5, spring 19 is welded inside the discharge pipe 5, arc block 18 is welded to one end of the spring 19, and the end of the arc block 18 away from the spring 19 extends into the cavity 12.

[0028] In use, first connect the external paint conveying pipeline to the branch pipe 7 outside the cylinder 6, then convey the paint to be tinted into the cavity 12 inside the cylinder 6. There are three sets of cavities 12 inside the cylinder 6. Then, the motor 1 on the bracket 9 drives the reducer 2 to rotate the drive rod 3 through the action of the PLC controller. The external stirring rods A10 and B13 of the drive rod 3 stir and mix the paint in the cavity 12. The drive rod 3 extends into the three cavities 12 through the bearing 15 inside the cylinder 6, and stirs the paint in the three cavities 12 simultaneously. The rubber blocks A14 and B16 outside the bearing 15 seal the bearing 15. After the paint is mixed, open the valve 4 on the discharge pipe 5 to discharge the paint from the discharge pipe 5.

[0029] When the paint is discharged from the discharge pipe 5, the drive rod 3 drives the stirring rod A10 and stirring rod B13 to rotate. Then the stirring rod B13 drives the external square plate 17 to rotate, and the square plate 17 scrapes the inner wall of the cavity 12, which facilitates the cleaning of the paint adhering to the cavity 12 and improves the utilization rate of the paint.

[0030] When the square plate 17 rotates to one side of the discharge pipe 5, the square plate 17 presses the arc-shaped block 18 inside the discharge pipe 5. Then the arc-shaped block 18 retracts into the discharge pipe 5, and the spring 19 at one end of the arc-shaped block 18 is compressed. When the square plate 17 moves away from the discharge pipe 5, the spring 19 drives the arc-shaped block 18 to pop outward, thereby generating suction in the discharge pipe 5 and improving the conveying efficiency of the paint.

[0031] To clean the paint on rubber blocks A14 and B16, for example, as follows: Figure 2As shown, the present invention also includes a scraper 11 welded to the outside of the stirring rod A10 to scrape the rubber block A14.

[0032] When in use, when the stirring rod A10 adjusts the color of the paint in the cavity 12, the scraper 11 on the stirring rod A10 scrapes the rubber block A14. There are multiple sets of stirring rods A10 outside the drive rod 3. The scraper 11 on another set of stirring rods A10 scrapes the rubber block B16, which makes it easier to clean the paint on the rubber block A14 and the rubber block B16.

[0033] For the protection of spring 19, exemplarily, such as Figure 1 , Figure 2 and Figure 3 As shown, the present invention also includes a rubber sleeve 20 that protects the spring 19.

[0034] During use, a rubber sleeve 20 is fixed to one side of the arc-shaped block 18 with screws, and the rubber sleeve 20 is located outside the spring 19, which facilitates the protection of the spring 19.

[0035] To improve the stability of cylinder 6, for example, such as Figure 1 As shown, the present invention also includes a base frame 8 that supports the cylinder 6 and is bolted to the bottom of the cylinder 6.

[0036] During use, the base frame 8 at the bottom of the cylinder 6 supports the cylinder 6, improving the stability of the cylinder 6.

[0037] For electrical equipment to function properly, for example, such as Figure 1 As shown, the present invention also includes that the input terminals of the motor 1 and the reducer 2 are both electrically connected to the power supply terminal of an external power source.

[0038] When in use, the electrical equipment works normally by connecting to an external power source.

[0039] In use, the external paint conveying pipeline is first connected to the branch pipe 7 outside the cylinder 6. Then, the paint to be tinted is conveyed into the cavity 12 inside the cylinder 6. There are three sets of cavities 12 inside the cylinder 6. The motor 1 on the support 9, through the action of the PLC controller, causes the reducer 2 to drive the drive rod 3 to rotate. The external stirring rods A10 and B13 of the drive rod 3 agitate and mix the paint in the cavities 12. The drive rod 3 extends into the three cavities 12 through the bearing 15 inside the cylinder 6, simultaneously agitating the paint in all three cavities 12. Rubber blocks A14 and B16 outside the bearing 15 seal the bearing 15. After the paint mixing is complete, the discharge pipe 5 is opened. Valve 4 allows paint to be discharged from discharge pipe 5. At the same time, drive rod 3 drives stirring rod A10 and stirring rod B13 to rotate. Then stirring rod B13 drives the external square plate 17 to rotate, and the square plate 17 scrapes the inner wall of cavity 12, which facilitates the cleaning of paint adhering to cavity 12 and improves paint utilization. When the square plate 17 rotates to one side of discharge pipe 5, the square plate 17 presses the arc block 18 in discharge pipe 5. Then the arc block 18 retracts into discharge pipe 5, and the spring 19 at one end of arc block 18 is compressed. When the square plate 17 moves away from discharge pipe 5, the spring 19 drives the arc block 18 to pop out, which generates suction in discharge pipe 5 and improves paint conveying efficiency.
