[0002] Precise paint consumption metering equipment for spray guns in coating production lines is a core auxiliary device in industrial coating fields such as automobile manufacturing, furniture coating, and hardware processing. Primarily used in mass production scenarios, its core function is to accurately measure the paint consumption of single or multiple spray guns in real time. This provides data support for production cost accounting, raw material ratio optimization, and production process control, making it a key piece of equipment for ensuring efficient, energy-saving, and standardized operation of coating production. As industrial manufacturing transitions towards refined management, higher demands are placed on the accuracy of paint consumption metering, ease of equipment disassembly and assembly, and adaptability to various operating conditions, requiring compatibility with different types of spray guns and complex coating environments.

[0003] In industrial coating production scenarios, there are core technological pain points.

Furthermore, the connection methods between metering equipment and spray guns and paint supply pipelines are complex, cumbersome to disassemble and assemble, affecting equipment maintenance and production line color change efficiency. In addition, paint is prone to leakage in the coating environment, and traditional equipment has insufficient sealing performance, not only wasting raw materials but also affecting metering accuracy and the cleanliness of the production environment, making it difficult to balance metering accuracy, ease of maintenance, and sealing reliability. Therefore, we propose a precise paint consumption metering device for spray guns in coating production lines. Utility Model Content

[0027] This application provides a precise metering device for paint consumption of spray guns in industrial scenarios such as automobile manufacturing painting lines, furniture batch painting workshops, and hardware spraying production lines. It effectively solves the problems of large metering errors, inconvenient disassembly and assembly, and poor sealing of traditional paint.

[0028] Existing paint metering equipment suffers from inaccurate data, low maintenance efficiency, and material waste due to a lack of precise docking structure, convenient disassembly and assembly design, and reliable sealing components. It is difficult to meet the core usage requirements of accurate metering, rapid maintenance, and reliable sealing in refined production.

[0029] like Figure 1 - Figure 4 As shown, the overall concept of the embodiments of this application is as follows:

[0030] With precise metering, convenient disassembly and assembly, and sealed protection as its core design logic, the paint delivery channel is built through the main paint supply pipe 1 and the branch pipe 2. The positioning and fixing structure of the connecting flange 1 6 and the connecting flange 2 7 ensures the docking accuracy. The data acquisition module 4 inside the outer shell 3 realizes flow metering. With the quick-release mechanism, the spray gun 5 can be quickly loaded and unloaded. The protection is strengthened by the sealing gasket, taking into account the metering accuracy, ease of operation and adaptability to working conditions.

[0031] The structure, installation method, connection relationship and details of each part of this utility model are as follows, to ensure that those skilled in the art can fully implement it based on the following description: The paint conveying and docking assembly includes a paint supply main pipe 1, a branch pipe 2, a connecting flange 1 6, and a connecting flange 2 7, which realizes the diversion and conveying of paint and the precise docking of the metering equipment.

[0032] The main paint supply pipe 1 is the main paint supply channel of the coating production line. Several branch pipes 2 are connected to it, and the branch pipes 2 are used to distribute the paint to each spray gun 5. A connecting flange 6 is fixed to the end of the branch pipe 2. A connecting flange 7 is adapted to be connected to the connecting flange 6. Bolt holes 8 are opened on both of them, and fixing bolts 9 are installed in the bolt holes 8 to achieve a stable connection between the two. A positioning pin 10 is protruding on the connecting flange 7. A positioning hole 11 adapted to the positioning pin 10 is opened on the connecting flange 6. The positioning pin 10 and the corresponding positioning hole 11 are inserted and matched to ensure coaxiality during docking and prevent leakage during paint delivery.

[0033] The metering and protection components include a housing 3, a data acquisition module 4, and a sealing gasket, which are used to measure paint consumption and provide sealing protection for the equipment.

[0034] A housing 3 is fixed to one side of the connecting flange 2 7. The housing 3 is a hollow cavity structure with a mounting base inside. The data acquisition module 4 is fixed to the mounting base by bolts. Its two ends are connected to the branch pipe 2 and the quick-release head 13 through sealing joints, respectively. It can collect the paint flow data in real time and complete the consumption measurement. Sealing gaskets are embedded at both ends of the housing 3. The sealing gaskets are tightly fitted to the connecting flange 2 7 and the pipe sleeve 12, respectively, to form a double seal, prevent paint leakage and external impurities from entering, and ensure the stable operation of the equipment in the coating environment.

[0035] The quick-release mechanism includes a sleeve 12, a quick-release head 13, a limit slider 16, and a spring 17, which enables the rapid assembly and disassembly of the metering equipment and the spray gun 5.

[0036] A sleeve 12 is fixed to the end of the outer casing 3 away from the connecting flange 7. A quick-release head 13 is fitted inside the sleeve 12. One end of the quick-release head 13 is connected to the spray gun 5, and the other end is connected to the data acquisition module 4 to achieve smooth paint delivery. An annular groove 14 is formed on the outer wall of the quick-release head 13, and a sliding groove 15 is formed on the inner wall of the sleeve 12. A limit slider 16 is slidably installed in the sliding groove 15. A spring 17 is connected between the limit slider 16 and the inner wall of the sliding groove 15. The spring 17 is always in a compressed state, pushing the limit slider 16 to fit into the annular groove 14 to fix the quick-release head 13 and the sleeve 12. A release port 18 is formed on the side wall of the annular groove 14. The release port 18 is connected to the sliding groove 15. When disassembly is required, the limit slider 16 is pushed through the release port 18 to compress the spring 17, causing it to disengage from the annular groove 14, so that the quick-release head 13 and the spray gun 5 can be quickly pulled out.

[0037] Additional details on scene adaptation:

[0038] 1. User and Equipment Compatibility: For spray guns 5 of different diameters, quick-release heads 13 of corresponding specifications can be replaced to improve equipment compatibility; for multi-spray gun production lines, multiple branch pipes 2 can be connected to the main paint supply pipe 1, and multiple sets of metering equipment can be used to achieve simultaneous metering of multiple spray guns; for high-viscosity paint scenarios, wear-resistant sealing joints and quick-release heads 13 can be selected to ensure smooth delivery.

[0039] II. Durability and Adaptability: The main paint supply pipe 1 and branch pipe 2 are made of corrosion-resistant metal with rust-proof surface treatment; the connecting flange 1 6 and connecting flange 2 7 are made of high-strength carbon steel; the positioning pin 10 and fixing bolt 9 are made of stainless steel, which is corrosion-resistant and has high strength; the limit slider 16 is made of wear-resistant engineering plastic to extend the sliding service life; the spring 17 is made of fatigue-resistant elastic material to ensure the elastic performance for long-term use.

[0041] The working principle of this device is as follows:

[0042] This device, centered on precise metering and rapid assembly / disassembly, achieves precise control over paint consumption during coating production through the coordinated operation of paint delivery, metering data acquisition, multi-spray gun connection, and equipment maintenance. The specific process is as follows:

[0043] Paint delivery and docking: The main paint supply pipe 1 delivers paint to each branch pipe 2. The positioning holes 11 of the connecting flange 1 6 are aligned with the positioning pins 10 of the connecting flange 2 7 to complete the positioning docking. Then, the fixing bolts 9 are inserted into the bolt holes 8 and tightened to achieve a stable connection between the branch pipe 2 and the outer shell 3. The sealing gaskets at both ends of the outer shell 3 are tightly fitted to the connecting flange 2 7 and the pipe sleeve 12 respectively to ensure sealing performance.

[0044] Metering and data acquisition: The paint flows into the data acquisition module 4 inside the outer casing 3 through the branch pipe 2. The data acquisition module 4 detects the paint flow in real time and accurately measures the paint consumption of a single spray gun 5, providing data support for production management.

[0045] Connection of the spray nozzle: Insert one end of the quick-release head 13 into the sleeve 12. Under the action of the spring 17, the limiting slider 16 automatically engages in the annular groove 14 of the quick-release head 13, thus fixing the quick-release head 13 to the sleeve 12. The other end of the quick-release head 13 is connected to the spray gun 5, and the spray gun 5 can be started to perform the spraying operation.

[0046] Equipment maintenance and disassembly: When it is necessary to replace the spray gun 5 or maintain the metering equipment, push the limit slider 16 out of the annular groove 14 through the release port 18 to quickly pull out the quick-release head 13 and the spray gun 5; loosen the fixing bolts 9, separate the connecting flange 1 6 and the connecting flange 2 7, and the data acquisition module 4 can be maintained or replaced. The operation is convenient and efficient.
