Description

Technical Field

[0001] This utility model relates to the field of paint production technology, specifically to an automated paint production line. Background Technology

[0002] In the production process of paint, multiple raw materials need to be poured into a reaction tank and stirred and mixed to obtain paint.

[0003] However, this approach presents several problems. Directly pouring multiple raw materials into the reaction vessel for mixing can lead to low mixing efficiency and uneven mixing due to factors such as high viscosity and high density of some raw materials (resulting in gravity stratification within the reaction vessel). Furthermore, the addition of raw materials to the reaction vessel is currently done manually by operators, which not only wastes a significant amount of manpower but also poses health risks to the operators due to the irritating gases produced during the pouring process.

[0004] Therefore, it is necessary to propose an automated paint production line to achieve fully automated paint production without human intervention, and to significantly improve mixing efficiency and make the raw materials more uniform compared to existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose an automated paint production line that realizes fully automated paint production without human intervention. Compared with the existing technology, it can significantly improve the mixing efficiency and make the raw materials more uniformly mixed.

[0006] The purpose of this utility model is achieved through the following technical solution: an automated paint production line, including a substrate, on which a reaction tank and a pre-stirring tank connected to the reaction tank are mounted, at least one feed pipe is slidably passed through the substrate, a first conveying pump for feeding raw materials from the feed pipe into the pre-stirring tank is provided between the feed pipe and the pre-stirring tank, and a second conveying pump for feeding raw materials from the pre-stirring tank into the reaction tank is provided between the reaction tank and the pre-stirring tank.

[0007] Both the reaction vessel and the pre-stirred vessel are equipped with rotatable stirring rods, and both the reaction vessel and the pre-stirred vessel are equipped with motors for driving the stirring rods to rotate.

[0008] The pre-mixing tank is provided with a feed inlet, and the feed inlet is detachably covered with a plug.

[0009] The reaction vessel and the pre-stirred vessel are equipped with pressure relief valves.

[0010] A control cabinet is mounted on the base plate.

[0011] The feed pipe is connected to a first pipeline and a second pipeline, both of which are connected to the reaction vessel. A first transport pump is installed on both the first pipeline and the second pipeline.

[0012] The first delivery pump has manual valves connected in parallel at both ends.

[0013] The pre-mixing tank is connected to a pre-mixing section, which is connected to multiple feed pipes. The height of the pre-mixing section near the reaction tank is lower than the height of the end near the pre-forming tank.

[0014] The reaction vessel is provided with a main pipeline with an opening at the bottom. The main pipeline is equipped with an on / off valve. The main pipeline is connected to a parallel pipeline parallel to the horizontal plane. The parallel pipeline is connected to a second conveying pump. The second conveying pump is connected to the bottom of the pre-mixing tank through a discharge pipe.

[0015] The inner walls on both sides of the pre-mixing tank are provided with grooves, and distance sensors are provided at both ends of the grooves. Floats are slidably installed at the grooves.

[0016] The beneficial effects of this utility model are:

[0017] (1) By setting up a first transport pump and a second transport pump, automatic feeding into the reaction tank is realized without the need for manual feeding, which greatly saves human resources and avoids the possibility of harm to the health of operators.

[0018] (2) By setting up a pre-stirring tank, multiple raw materials are pre-stirred first, and then sent into the reaction tank for complete and thorough stirring, thereby solving the problems of high viscosity of raw materials and high density of some raw materials, avoiding gravity stratification in the reaction tank, thereby greatly improving the stirring efficiency and making the raw materials more uniformly stirred.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0026] An automated paint production line, reference Figures 1-4 The system includes a base plate 1. A reaction vessel 2 and a pre-stirring vessel 3 are fixedly mounted on the base plate 1. A stirring rod 7 is rotatably mounted inside both the reaction vessel 2 and the pre-stirring vessel 3. A motor 8 for driving the stirring rod 7 is located at the center of the upper end of both the reaction vessel 2 and the pre-stirring vessel 3. A pressure relief valve 11 is installed at the upper end of both the reaction vessel 2 and the pre-stirring vessel 3. A main pipeline 17 communicating with the interior of the reaction vessel 2 is located at the bottom. An on / off valve 18 for controlling the opening and closing of the main pipeline 17 is installed on the main pipeline 17. Under normal conditions, the lower end of the main pipeline 17 is closed. A plug cap can be screwed onto the lower end of the main pipeline 17; the plug cap is removed only when the paint mixed in the reaction vessel needs to be connected. A parallel pipe 19 communicating with the horizontal plane is provided on the side wall of the main pipeline 17. A discharge pipe 20 is connected to the lower end of the pre-stirring vessel 3. The parallel pipe 19 and the discharge pipe 20 are connected to both ends of the second conveying pump 6. A control cabinet 12 is mounted on the base plate 1.

[0027] After the pre-mixing tank pre-mixes the raw materials, the on / off valve 18 opens, and the second delivery pump 6 operates, sending the raw materials from the pre-mixing tank into the reaction tank 2 for thorough mixing. After the mixing is complete, the on / off valve 18 closes. Once the reaction tank 2 has finished mixing, the lower end of the main pipeline 17 opens, the on / off valve 18 opens, and the paint in the reaction tank 2 is discharged from the main pipeline 17 into the paint bucket located directly below the main pipeline 17.

[0028] The pre-mixing tank 3 has a feed inlet 9, and a detachable plug 10 is installed on the feed inlet 9. When there is a problem with the feed pipe 4, the missing raw material can be poured in through the feed inlet 9.

[0029] Multiple feed pipes 4 are installed on the substrate 1. These feed pipes 4 are used to transport paint raw materials, with different feed pipes 4 corresponding to different paint raw materials. The upper ends of the feed pipes 4 are connected to a first pipeline 13 and a second pipeline 14. A first delivery pump 5 is installed on both the first pipeline 13 and the second pipeline 14. A manual valve 15 is installed on both the first pipeline 13 and the second pipeline 14, connected in parallel with the first delivery pump 5. The first pipeline 13 is the primary operating pipeline, and the second pipeline 14 is the backup pipeline. When the first pipeline 13 malfunctions, the second pipeline 14 starts to ensure uninterrupted raw material supply. When the first delivery pump 5 malfunctions, the manual valve 15 opens, acting as a substitute for the first delivery pump 5. Multiple first pipelines 13 and multiple second pipelines are connected to premixing sections 16, and both premixing sections 16 are connected to pre-stirring tanks 3. The height of the premixing section 16 near the pre-stirring tank 3 is higher than the height of the premixing section 16 near the reaction tank 2. When the raw materials are introduced into the premixing section 16, they can be premixed first in the premixing section 16.

[0030] The pre-mixing tank 3 has grooves 21 on both side walls. Gap sensors 22 are installed at the upper and lower ends of the grooves 21. A float 23 is slidably mounted on the grooves 21. The gap sensors 22 detect the distance between the float 23 and the float, thereby determining the amount of raw material in the pre-mixing tank 3 and adjusting the feed rate in real time.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above description or the technology or knowledge in related fields.
