[0002] In the modern industrial and decoration fields, the use of paints is extensive and diverse. It is crucial to accurately formulate paint colors, properties, and quality that meet specific requirements.

[0003] However, traditional paint mixing methods often have many problems:

[0004] 1. During the open paint mixing process, the solvents in the paint are likely to volatilize into the air, not only causing waste of materials but also posing a threat to the environment and the health of operators.

[0005] 2. Due to interference from external factors, such as the mixing of dust and impurities, the accuracy of traditional paint mixing is often difficult to reach the ideal level, which may lead to color deviation and unstable performance of the formulated paint. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a paint mixing tank for closed production, so as to solve the impact of the existing open paint mixing tank on paint quality production.

[0007] The utility model is realized through the following technical solutions:

[0008] A paint mixing tank for closed production includes a tank body. The tank body is threadedly connected to a tank cover. A rotary motor is arranged at the middle position of the upper surface of the tank cover. An upward-opening feeding device with a cover is arranged beside the rotary motor. The extension pipe below the rotary motor penetrates through the tank cover and enters the tank body to be connected to the cleaning and stirring assembly below. A switchable discharge port is arranged at the bottom of the tank body. Four vertical columns perpendicular to the bottom surface of the tank body are established on the outer surface of the bottom of the tank body. A full overflow determination assembly is vertically installed at the lower end of each column.

[0009] By the threaded connection between the tank body and the tank cover, the feeding device with a cover, and the switchable discharge port, it is ensured that the space inside the tank is closed during paint mixing. The cleaning and stirring assembly has the functions of cleaning and stirring. The cleaning device and the stirring device are designed as a whole, with a simpler structure. The full overflow determination assembly determines whether to add materials to the tank by whether the height of the tank body changes.

[0010] Furthermore,

[0011] The feeding device includes a handle and a feeding cover. The handle is arranged on the upper surface of the feeding cover, and the feeding cover can be adapted to the feeding port.

[0012] Furthermore,

[0013] The cleaning and stirring assembly includes a main rod, a cross plate, an arc plate, a side wall scraper, a bottom short rod, and a bottom scraper. The upper end of the main rod is connected to an extension pipe and is vertically arranged inside the tank. A cross plate parallel to the bottom is installed at the middle position of the main rod. Arc plates are perpendicularly connected to both ends of the cross plate. A side wall scraper equal in height to the arc plate and parallel to the main rod is arranged on the outer side of the arc plate. Bottom short rods are installed on the side surface of the tail end of the main rod at equal angular intervals and parallel to the tank bottom, and a bottom scraper is vertically arranged below the bottom short rods.

[0014] Furthermore,

[0015] The overflow determination assembly includes a housing, a limit plate, a strut spring, and a strut.

The strut passes through the upper surface of the housing and is connected to the limit plate. The limit plate is connected to the strut spring below, and the other end of the strut spring is connected to the bottom of the housing.

[0016] Furthermore,

[0017] The upper end of the main rod can be inserted into the extension pipe. Fixed rods are arranged at corresponding positions on both sides of the main rod, and inverted "J"-shaped clamping grooves are opened at corresponding positions on both sides of the extension pipe. The clamping grooves can clamp the fixed rods to fix the main rod.

[0018] Furthermore,

[0019] The arc plate is parallel to the main rod. The height of the arc plate should be equal to the height of the material loading area of the tank body, and the outer arc of the arc plate is the same as the inner wall arc of the tank body.

[0020] Furthermore,

[0021] The side wall scraper is perpendicular to the arc plate, and the width of the side wall scraper is equal to the distance between the arc plate and the inner wall of the tank body.

[0022] Furthermore,

[0040] Embodiment

[0041] See Figures 1 to 6 :

[0042] A closed paint mixing tank for production, comprising a tank body 1, the tank body 1 is threadedly connected to a tank cover 7, a rotary motor 2 is arranged at the middle position of the upper surface of the tank cover 7, an upward-opening and covered feeding device 3 is arranged beside the rotary motor 2, an extension pipe 21 below the rotary motor 2 penetrates through the tank cover 7 and enters the tank body 1 to be connected to a cleaning and stirring assembly 4 below, a switchable discharge port 8 is arranged at the bottom of the tank body 1, four columns 5 perpendicular to the bottom of the tank body are established on the outer surface of the bottom of the tank body 1, and an overflow determination assembly 6 is vertically installed at the lower end of each column 5.

[0043] The tank cover 7 is threadedly connected to the tank body 1, ensuring that the inside of the tank body 1 is a sealed space when the tank cover 7 is closed. The rotary motor 2 drives the cleaning and stirring assembly 4 below to rotate, while stirring the material and removing the material adhered to the inner wall. During the feeding process, as the material in the tank body 1 increases, the height of the tank body 1 will slowly drop due to the overflow determination assembly 6. When it no longer drops, it means that the material has been filled up.

[0044] Furthermore,

[0045] The feeding device 3 includes a handle 31 and a feeding cover 32. The handle 31 is arranged on the upper surface of the feeding cover 32, and the feeding cover 32 can be adapted to the feeding port.

[0046] The setting handle 31 is provided to enable the staff to more easily open the feeding cover 32. After the feeding is completed, the feeding cover 32 is closed. Since the feeding cover 32 is adapted to the feeding port, it ensures that the inside of the tank is a closed space.

[0047] Furthermore,

[0048] The cleaning and stirring assembly 4 includes a main rod 41, a cross plate 42, an arc plate 43, a side wall scraper 44, a bottom short rod 45, and a bottom scraper 46. The upper end of the main rod 41 is connected to the extension pipe 21 and is vertically disposed inside the tank body 1. A cross plate 42 parallel to the bottom is installed at the middle position of the main rod 41. The two ends of the cross plate 42 are respectively vertically connected to the arc plates 43. The outer side of the arc plate 43 is provided with a side wall scraper 44 that is equal in height to the arc plate 43 and parallel to the main rod 41. The side of the tail end of the main rod 41 is installed with bottom short rods 45 at equal angular intervals and parallel to the tank bottom. A bottom scraper 46 is vertically disposed below the bottom short rod 45.

[0049] During stirring, the side wall scraper 44 can remove the materials adhered to the inner wall of the tank body 1, and the bottom scraper 46 can remove the materials adhered to the bottom of the tank body 1. At the same time, the cross plate 42, the arc plate 43, the side wall scraper 44, the bottom short rod 45, and the bottom scraper 46 all play a role in stirring the materials.

[0050] Furthermore,

[0051] The full overflow determination assembly 6 includes a housing 60, a limit plate 61, a pillar spring 62, and a pillar 63. The housing 60 is a hollow housing, and a pillar 63 with a height lower than the pillar spring 62 is installed at the bottom. The vertical column 5 passes through the upper surface of the housing 60 and is connected to the limit plate 61. The limit plate 61 is connected to the pillar spring 62 below, and the other end of the pillar spring 62 is connected to the bottom of the housing 60.

[0052] As the materials inside the tank body 1 increase, the weight of the tank body 1 increases, compressing the pillar spring 62, and the height of the tank body 1 slowly decreases. When the materials inside the tank body 1 reach the specified full state, the limit plate 61 contacts the pillar 63, and the height of the tank body 1 no longer changes. Then it can be known that the materials are full, and the feeding is stopped.

[0053] Furthermore,

[0054] The upper end of the main rod 41 can be inserted into the extension pipe 21. Fixed rods 420 are provided at the corresponding positions on both sides of the main rod 41. Inverted "J"-shaped clamping grooves 22 are opened at the corresponding positions on both sides of the extension pipe 21. The clamping grooves 22 can clamp the fixed rods 420 to fix the main rod 41.

[0055] The main rod 41 and the extension pipe 21 form a detachable fixed structure, which can more conveniently clean the cleaning and stirring assembly 4.

[0056] Further,

[0057] The arc-shaped plate 43 is parallel to the main rod 41. The height of the arc-shaped plate 43 should be equal to the height of the loading area of the tank body 1, and the outer arc of the arc-shaped plate 43 is the same as the inner wall arc of the tank body 1.

[0058] Ensure that the vertical distance between the arc-shaped plate 43 and the inner wall of the tank body 1 is equal.

[0059] Further,

[0060] The side wall scraper 44 is perpendicular to the arc-shaped plate 43, and the width of the side wall scraper 44 is equal to the distance between the arc-shaped plate 43 and the inner wall of the tank body 1.

[0061] Ensure that the side wall scraper 44 can just contact the inner wall of the tank body 1.

[0062] Further

[0063] The height of the bottom scraper 46 should be equal to the distance between the bottom short rod 45 and the tank bottom. Ensure that the bottom scraper 46 can just contact the tank bottom.

[0064] The usage method of the present utility model is as follows:

[0065] Before stirring the materials, tightly connect the tank cover 7 and the tank body 1 through threads. After opening the feeding cover 32 through the handle 31, add the materials to be stirred into the tank body 1 from the feeding port.

[0066] During the feeding process, because the amount of materials is increasing and the total weight of the tank body 1 is getting larger and larger, the pillar spring 62 in the full overflow determination component 6 will be compressed, and then the tank body 1 will slowly descend. When the total amount of materials added reaches a certain level, the limit plate 61 at the lower end of the column 5 will contact the pillar 63, and then the tank body 1 will stop descending and the height will no longer change. The staff will know that the materials have reached the specified amount and then stop feeding.

[0067] After stopping the feeding, close the feeding cover 32. The feeding cover 32 is adapted to the feeding port, and the feeding cover 32 can completely seal the feeding port, ensuring that the inside of the tank is a closed space. Then start the rotating motor 2 to drive the extension pipe 21 to rotate. The main rod 41 connected to the extension pipe 21 also rotates together, causing the cross plate 42 on the main rod 41, the arc plates 43 at both ends, the side wall scraper 44 outside the arc plates 43, the bottom short rod 45 on the side of the lower end of the main rod 41, and the bottom scraper 46 at the lower end of the bottom short rod 45 to rotate together with the main rod 41. The side wall scraper 44 can scrape the materials adhered to the inner wall of the tank body 1, and the bottom scraper 46 can scrape the materials adhered to the bottom of the tank body 1, ensuring that there is no adhesion of materials on the inner wall and bottom of the tank, saving a certain amount of materials. The cross plate 42, the arc plates 43, the side wall scraper 44, the bottom short rod 45, and the bottom scraper 46 can all stir the materials, enabling stirring and cleaning to be carried out at the same time.

[0068] After the stirring is completed, just turn off the rotating motor 2.

[0069] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Based on the technical essence of the present invention, any simple modification, equivalent replacement, and improvement made to the above embodiments within the spirit and principle of the present invention still fall within the protection scope of the technical solution of the present invention.
