Description

Technical Field

[0001] This utility model relates to the field of paint production technology, and in particular to a storage tank for paint production. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, providing protection, decoration, marking, and other special purposes. The paint production process requires the use of storage tanks. Currently, storage tanks are used in many production processes. As the name suggests, a storage tank is a container that can store materials. Various storage tanks can be designed and manufactured according to user requirements.

[0003] However, the pigments, resins, solvents and other components in paint have different densities, making them prone to sedimentation and stratification during storage. Existing single fixed stirring paddles have limited stirring range and cannot reach all layers and corners of the tank, thus failing to effectively solve the stratification problem. This results in large differences in concentration and performance of different parts of the same batch of paint, affecting the subsequent coating effect. Utility Model Content

[0028] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1-5 A storage tank for paint production includes a tank body 1, on which an anti-solidification component 3 is mounted. A mounting shell 2 is provided on the top surface of the tank body 1 to protect the anti-solidification component 3 and reduce dust erosion. The anti-solidification component 3 includes a stirring component 33 and a pushing component 31 that enables the stirring component 33 to move vertically relative to the tank body 1. The stirring component 33 and the pushing component 31 are connected by a transmission component 32.

[0030] The pushing component 31 includes a wedge block 312 that can rotate around a central axis, and the bottom surface of the wedge block 312 is arranged at an inclination. A groove 313 is provided on the bottom surface of the wedge block 312. It should be noted that the wedge block 312 rotates preferably by a first rotating shaft 311 rotatably arranged on the top surface of the storage tank body 1, and the wedge block 312 is fixedly connected to the first rotating shaft 311. A driving component, preferably a servo motor, is provided at the end of the first rotating shaft 311 to drive the first rotating shaft 311 to rotate.

[0031] The stirring assembly 33 includes a movable shaft 332, on which stirring blades 334 for stirring paint are provided. The upper end of the movable shaft 332 is provided with a slider that can slide inside the groove 313, and the slider is provided with rolling balls 34 arranged inside the groove 313, which can reduce the resistance when the wedge block 312 rotates.

[0032] Specifically, a servo motor is used as the power source to drive the first rotating shaft 311 to rotate. The first rotating shaft 311 drives the wedge block 312 to rotate, and the rotation of the transmission assembly 32 drives the shaft seat 331 to rotate. Since the bottom surface of the wedge block 312 is inclined, a height difference is generated, which causes the movable shaft 332 to move downward. Under the action of the limit bar 333, the shaft seat 331 drives the movable shaft 332 to rotate. Then, as the wedge block 312 rotates, the movable shaft 332 can move upward, thereby realizing the movement of the movable shaft 332. While the stirring blades 334 are stirring the paint inside the storage tank body 1 at the same level, the reciprocating motion of the movable shaft 332 causes the stirring blades 334 to stir and flow the paint at different levels inside the storage tank body 1. It can penetrate to different heights in the tank and perform targeted stirring of each layer of paint, strongly agitating components of different densities, so that the settled pigments are redispersed evenly in the resin and solvent, breaking up the stratification, ensuring that the paint composition of the whole tank is uniform and consistent, greatly improving the stability of product quality, and avoiding problems such as coating color difference and poor adhesion caused by uneven paint performance.

[0033] Furthermore, the stirring assembly 33 also includes a bearing 331 rotatably connected to the top surface of the storage tank body 1;

[0034] The side wall of the movable shaft 332 is provided with a limiting strip 333 with a square cross-section, and both the movable shaft 332 and the limiting strip 333 are provided inside the shaft seat 331. This ensures that while the pushing component 31 pushes the movable shaft 332 downward, the rotation of the movable shaft 332 driven by the shaft seat 331 will not be affected.

[0035] Furthermore, a connecting block 36 is provided on the side wall of the movable shaft 332, and a spring 35 is provided on the connecting block 36 and arranged between the storage tank body 1 and the connecting block 36, which plays the role of assisting in lifting the movable shaft 332.

[0036] Furthermore, the transmission assembly 32 includes a driving gear 321 and a driven gear 322 that mesh with each other, and the driving gear 321 is fixedly connected to a first rotating shaft 311, and the driven gear 322 is fixedly connected to a bearing 331.

[0037] Specifically, the drive gear 321 can be driven to rotate by the first rotating shaft 311, while the driven gear 322 rotates. The driven gear 322 drives the bearing seat 331 to rotate, and the bearing seat 331 drives the limit bar 333 and the movable shaft 332 to rotate.

[0038] Furthermore, a discharge port 13 is provided through the lower part of the storage tank body 1. It should be noted that a valve 14 is provided on the discharge port 13. When the storage tank body 1 is storing paint, the valve 14 is closed. When the paint is being discharged from the storage tank body 1, the valve 14 can be opened. A paint scraping mechanism 4 is installed on the discharge port 13.

[0039] The paint scraping mechanism 4 includes an annular guide rail 42 arranged on the outside of the storage tank body 1 via a first fixing rod 41. The bottom surface of the annular guide rail 42 is connected to a scraper block 49 for scraping the paint on the inner and outer walls of the outlet 13 via a connecting frame 48. It should be noted that the scraper block 49 is U-shaped and fits against the inner and outer walls of the outlet 13. It can scrape off the paint that has solidified on the outlet of the anti-solidification component 3 during the sliding of the slide block 43 along the annular guide rail 42.

[0040] The paint scraping mechanism 4 also includes a drive assembly for driving the slide block 43 to slide along the annular guide rail 42.

[0041] Specifically, during the process of releasing paint from the inside of the storage tank body 1, the sliding block 43 can slide along the annular guide rail 42 through the drive component, and then through the transmission of the connecting frame 48, the scraper 49 will scrape off the paint that is not dripping from the closed outlet 13, thus avoiding the problem of paint drying and adhering to the outlet 13 and blocking the outlet 13.

[0042] Furthermore, the drive assembly includes a second rotating shaft 46 rotatably connected to the slide 43. It should be noted that the end of the second rotating shaft 46 is provided with a drive source, preferably a servo motor, for driving the second rotating shaft 46 to rotate. A movable gear 47 is fixedly connected to the second rotating shaft 46.

[0043] Furthermore, the drive assembly also includes a fixed gear ring 45 connected to the outer wall of the storage tank body 1 via a second fixing rod 44, and the fixed gear ring 45 is meshed with the movable gear 47.

[0044] Specifically, a servo motor is used as a power source to drive the second rotating shaft 46 to rotate, the second rotating shaft 46 drives the movable gear 47 to rotate, and then under the action of the fixed gear ring 45, the slide 43 slides along the annular guide rail 42.

[0045] Furthermore, the annular guide rail 42, the fixed toothed ring 45, and the discharge port 13 are all arranged concentrically.

[0046] Furthermore, the storage tank body 1 is composed of two outer walls, and a vacuum chamber 15 is provided between the two outer walls. It should be noted that the outer walls are preferably made of stainless steel, and the vacuum chamber 15 can reduce the impact of the external ambient temperature on the paint inside the storage tank body 1.

[0047] Furthermore, a feed inlet 11 is provided on the top surface of the storage tank body 1, and a can lid 12 is provided on the feed inlet 11 for use with it. Paint can be poured into the interior of the storage tank body 1 through the feed inlet 11, thereby preserving the paint. The can lid 12 and the feed inlet 11 need to be sealed, preferably by using a sealing ring to increase the sealing effect.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
