A paint supply system

Abstract

This application discloses a paint supply system, including a paint bucket, a power pump, a spray gun, a temperature controller, and an outer jacket. The paint bucket, power pump, and spray gun are connected sequentially via pipes. The power pump pumps paint from the paint bucket to the spray gun, which then sprays the paint. The outer jacket is fitted over the paint bucket, forming a heating chamber between the jacket and the paint bucket. The temperature controller is connected to the heating chamber via an inlet pipe, and the heating chamber is connected to the temperature controller via an outlet pipe. The temperature controller supplies heated water to the heating chamber via the inlet pipe. The heated water in the heating chamber exchanges heat with the paint bucket to heat the paint inside. After heat exchange, the heated water flows back to the temperature controller for further heating, completing the heating water circulation and reducing the viscosity of the paint. This paint supply system, through the cooperation of the outer jacket and the temperature controller, can use high-concentration paint to solve the problems of sagging and waste associated with low-concentration paint, ensuring coating quality. Simultaneously, heating reduces the viscosity of high-concentration paint flowing within the supply system, preventing blockages and maintaining stable production.

Description

Technical Field

[0001] This application relates to the field of spraying technology, and in particular to a paint supply system. Background Technology

[0002] In existing technologies, low-concentration paint is commonly used for battery cell spraying to avoid severe dripping after spraying. However, due to its low viscosity, low-concentration paint is still prone to flowing and dripping when sprayed onto the surface of the battery cell. This not only leads to uneven coating thickness and sagging defects, but also causes paint waste, seriously affecting the spraying quality and production efficiency. If high-concentration paint is used to improve the dripping problem, although it can improve the paint adhesion stability and reduce the risk of sagging, its high viscosity characteristics will significantly hinder the normal operation of the paint supply system. Utility Model Content

[0003] In view of the shortcomings of the prior art, this application provides a paint supply system that can solve the problem that the use of high-viscosity paint in existing paint supply systems will significantly hinder the normal operation of the paint supply system.

[0004] To address the aforementioned technical problems, this application discloses a paint supply system, comprising a paint bucket, a power pump, a spray gun, a thermostat, and an outer jacket. The paint bucket, the power pump, and the spray gun are sequentially connected via pipes. The outer jacket is fitted over the paint bucket and forms a heating chamber with the paint bucket. The thermostat is connected to the outer jacket via an inlet pipe, and the outer jacket is connected to the thermostat via an outlet pipe.

[0014] Compared to existing technologies, this application provides a paint supply system including a paint bucket, a power pump, a spray gun, a temperature controller, and an outer jacket. The paint bucket, power pump, and spray gun are connected sequentially via pipes. The power pump pumps paint from the paint bucket to the spray gun, which then sprays the paint. The outer jacket is fitted over the paint bucket, forming a heating chamber between them. The temperature controller is connected to the heating chamber via an inlet pipe, and the heating chamber is connected to the temperature controller via an outlet pipe. The temperature controller supplies heated water to the heating chamber via the inlet pipe. The heated water in the heating chamber exchanges heat with the paint bucket to heat the paint inside. After heat exchange, the heated water flows back to the temperature controller for further heating, completing the heating water circulation and reducing the viscosity of the paint. Using this design, this paint supply system, through the cooperation of the outer jacket and the temperature controller, can use high-concentration paint to solve the problems of sagging and waste associated with low-concentration paint, ensuring coating quality. Simultaneously, heating reduces the viscosity of high-concentration paint flowing within the supply system, preventing blockages and maintaining stable production. Attached Figure Description

[0020] The instruction or implication refers to a device or component that must have a specific orientation, be constructed and operated in a specific orientation.

[0021] Please see Figure 1 The paint supply system provided in this application includes a paint bucket 10, a power pump 20, a spray gun 40, a thermostat 40, and an outer jacket 50. The paint bucket 10, power pump 20, and spray gun 40 are connected sequentially via pipes. The power pump 20 pumps the paint from the paint bucket 10 to the spray gun 40, which then sprays the paint. The outer jacket 50 is fitted over the paint bucket 10, forming a heating chamber 51 between the jacket and the bucket. The thermostat 40 is connected to the heating chamber 51 via an inlet pipe, and the heating chamber 51 is connected to the thermostat 40 via an outlet pipe. The thermostat 40 supplies heated water to the heating chamber 51 via the inlet pipe. The heated water in the heating chamber 51 exchanges heat with the paint bucket 10 to heat the paint inside. After heat exchange, the heated water flows back to the thermostat 40 for further heating, completing the heating water circulation and reducing the viscosity of the paint. With this design, the paint supply system, through the cooperation of the outer jacket 50 and the constant temperature machine 40, can use high-concentration paint to solve the problems of dripping and waste of low-concentration paint, ensuring coating quality. At the same time, heating reduces the viscosity of high-concentration paint when flowing in the paint supply system, preventing paint supply blockage and maintaining stable production. In addition, since the outer jacket 50 is fitted outside the paint tank 10, the heating chamber 51 formed by it surrounds the paint tank 10, which can effectively maintain the temperature of the paint inside the paint tank 10.

[0022] Furthermore, considering that the paint heated in the paint bucket 10 will gradually decrease in temperature due to heat loss during the process of being transported to the spray gun 40, the paint supply system can also include a heater 60 to solve this problem. The paint inlet of the heater 60 is connected to the power pump 20 via a pipe, and the paint outlet of the heater 60 is connected to the spray gun 40 via a pipe. With this design, the heated paint in the paint bucket 10 can be reheated by the heater 60 before being transported to the spray gun 40, thereby ensuring that the paint remains at a high temperature and low viscosity when it is transported to the spray gun 40.

[0023] The connecting pipe between the power pump 20 and the heater 60 is made of thermal insulation material. This design allows the thermally insulated connecting pipe to provide some insulation for the paint, thus slowing down the cooling rate during the paint's transport from the power pump 20 to the heater 60.

[0024] Furthermore, the paint supply system may also include a pneumatic agitator 70, which is located in and extends into the paint tank 10. With this design, when the paint supply system is running, the pneumatic agitator 70 is activated and agitates the paint in the paint tank 10. This prevents the paint from settling and ensures that the paint is heated evenly, resulting in a higher quality paint output.

[0025] In some embodiments, the paint supply system may further include a filter 80, with the paint inlet of the filter 80 connected to the power pump 20 via a pipe, and the paint outlet of the filter 80 connected to the spray gun 40 via a pipe. With this design, the filter 80 can remove impurities and particles that may be present in the paint, preventing them from clogging the spray gun 40 or scratching the battery cell coating, thus ensuring the quality of the coating and the normal operation of the spray gun 40. Simultaneously, it can reduce the wear of impurities on subsequent pipelines and components, lower the risk of equipment failure, further maintain the stable operation of the paint supply system, and reduce maintenance downtime.

[0026] In some embodiments, the paint supply system also includes a flow meter 90, which is located in the connecting pipe between the power pump 20 and the spray gun 40, and is used to regulate the flow rate between the power pump 20 and the spray gun 40. With this design, when the paint supply system needs to paint different types of battery cells, the flow rate of the spray gun 40 can be adjusted by the flow meter 90 to meet the usage requirements of different types of battery cells.

[0027] In some embodiments, the paint supply system also includes a pressure sensor 100, which is located in the connecting pipe between the power pump 20 and the spray gun 40, and is used to detect the paint supply pressure at the spray gun 40. This design allows for real-time monitoring of the paint supply pressure before the spray gun 40, preventing coating defects caused by pressure fluctuations and ensuring coating quality; it also enables timely detection of abnormalities such as pipe blockage or leakage, providing early warning of equipment risks and reducing paint waste.

[0028] In some embodiments, the paint supply system further includes a first control valve 110, which is located at the spray gun 40 and is used to control the opening or closing of the spray gun 40. With this design, when the paint supply system is in a paint supply state, the first control valve 110 is open, and paint is sprayed from the spray gun 40 under the action of the power pump 20; when the paint supply system is not in a paint supply state, the second control valve 120 is closed, that is, the spray gun 40 is shut off, to prevent accidental spraying from the spray gun 40.

[0029] In some embodiments, the paint supply system further includes a second control valve 120, and the spray gun 40 is also connected to an air generator via a second air duct. The second control valve 120 is located in the second air duct. The air generator supplies air to the spray gun 40. When the paint supply system is not supplying paint, the second control valve 120 opens, and the air and paint in the spray gun 40 mix, causing the spray gun 40 to spray atomized paint. When the paint supply system is not supplying paint, the second control valve 120 closes. This design reduces spray pressure and nozzle wear by combining high-pressure spraying with air assistance, thus extending nozzle life. Furthermore, reducing paint pressure decreases paint velocity, reducing paint particle rebound efficiency and theoretically increasing paint yield.

[0030] The power pump 20, heater 60, and spray gun 40 are all connected to the paint bucket 10 via a return pipe to return any remaining paint to the paint bucket 10. This design, where the power pump 20, heater 60, and spray gun 40 are connected to the paint bucket 10 via a return pipe, allows any remaining paint in each device to be directly returned to the paint bucket 10. This avoids material waste caused by paint residue, effectively reduces construction costs, and prevents paint from drying and hardening in the equipment's pipes and components, reducing blockages, adhesion, and other malfunctions, thus extending the equipment's service life.

[0031] In some embodiments, the paint supply system also includes a controller 130, to which the thermostat 40, flow meter 90, and pressure sensor 100 are electrically connected. The controller 130 is used to control the operating parameters of the thermostat 40, flow meter 90, and temperature sensor.

[0032] This application provides a paint supply system including a paint bucket 10, a power pump 20, a spray gun 40, a thermostat 40, and an outer jacket 50. The paint bucket 10, power pump 20, and spray gun 40 are connected sequentially via pipes. The power pump 20 pumps paint from the paint bucket 10 to the spray gun 40 for spraying. The outer jacket 50 is fitted over the paint bucket 10, forming a heating chamber 51 between the jacket and the paint bucket 10. The thermostat 40 is connected to the heating chamber 51 via an inlet pipe, and the heating chamber 51 is connected to the thermostat 40 via an outlet pipe. The thermostat 40 supplies heated water to the heating chamber 51 via the inlet pipe. The heated water in the heating chamber 51 exchanges heat with the paint bucket 10 to heat the paint inside. After heat exchange, the heated water flows back to the thermostat 40 for further heating, completing the heated water circulation and reducing the viscosity of the paint. With this design, the paint supply system, through the cooperation of the outer jacket 50 and the constant temperature machine 40, can use high-concentration paint to solve the problems of dripping and waste of low-concentration paint, ensuring coating quality. At the same time, heating reduces the viscosity of high-concentration paint when flowing in the paint supply system, preventing paint supply blockage and maintaining stable production. In addition, since the outer jacket 50 is fitted outside the paint tank 10, the heating chamber 51 formed by it surrounds the paint tank 10, which can effectively maintain the temperature of the paint inside the paint tank 10.
