[0035] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figure 1-7 As shown, a paint supply device for a paint dripping equipment includes:

[0037] The frame 1 has at least one paint dripping station along its length.

[0038] The main paint station 3 includes a main paint tank 31 and a first pump body 32, the suction end of the first pump body 32 being connected to the main paint tank 31;

[0039] Three paint distribution devices are installed on the frame 1. Each paint distribution device includes a paint tank 41 and multiple second pump bodies (not shown in the figure). The side wall of the paint tank 41 is provided with a paint inlet 43 and the bottom is provided with a paint outlet 44. The paint inlet 43 is connected to the discharge end of the first pump body 32. The suction end of the second pump body is connected to the paint outlet 44, and the discharge end is connected to the connection port corresponding to the dripping station.

[0040] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the main paint station 3 stores paint through the main paint tank 31. The suction end of the first pump body 32 is connected to the main paint tank 31, drawing paint from the main paint tank 31 and conveying it through the discharge end of the first pump body 32 to the distribution tank 41 of the paint distribution device. The paint enters the interior of the distribution tank 41 through the paint inlet 43 on the side wall of the distribution tank 41 for temporary storage. The paint outlet 44 at the bottom of the distribution tank 41 is connected to the suction end of the second pump body. The second pump body conveys the paint in the distribution tank 41 through its discharge end to the dripping station 2 on the frame 1 for dripping operation. Through the two-stage paint supply structure of centralized paint supply by the main paint station 3 and decentralized distribution by the distribution paint supply device, the graded delivery and distribution of paint from the main paint tank 31 to each dripping station 2 is realized, avoiding the problems of pressure fluctuation and uneven flow caused by each station directly taking paint from the main paint tank 31, and ensuring that each dripping station 2 receives a constant supply of paint.

[0041] In this embodiment, a paint-drip device is provided at each paint-drip station. Each paint-drip device has two connection ports for simultaneously dripping paint onto two workpieces. Each paint-distribution device is connected to the two connection ports of the corresponding paint-drip device through two second pump bodies, thereby achieving simultaneous paint supply to two workpieces.

[0042] In this embodiment, the number of second pump bodies is set one-to-one with the number of connection ports of the connected paint dripping equipment, that is, each connection port is equipped with a second pump body to ensure the stability and independent control of paint supply. The first pump body 32 can specifically be a gear pump.

[0043] Specifically, such as Figure 1 As shown, the paint supply device for the paint dripping equipment also includes a chiller unit 5, which is provided with a chilled water outlet and a return water inlet.

[0044] The main paint tank 31 includes a tank body 311 and a water circulation jacket 312 disposed on the outer wall of the tank body 311. The water circulation jacket 312 is provided with a jacket inlet and a jacket outlet.

[0045] The chilled water outlet of chiller unit 5 is connected to the jacket inlet, and the return water inlet is connected to the jacket outlet.

[0046] Specifically, such as Figure 3 and Figure 6 As shown, the paint tank 41 includes an inner tank 411 and an outer tank 412. The inner tank 411 is disposed inside the outer tank 412. A temperature control interlayer 413 is formed between the inner tank 411 and the outer tank 412. The outer tank 412 is provided with a circulation inlet 414 and a circulation outlet 415 that are connected to the temperature control interlayer 413.

[0047] The chilled water outlet of the chiller unit 5 is connected to the circulating water inlet 414, and the return water inlet is connected to the circulating water outlet 415.

[0048] In this embodiment, as Figure 1 , Figure 3 and Figure 5As shown, the chilled water outlet of chiller unit 5 is connected to the jacket inlet of the main paint tank 31 and the circulating inlet 414 of the paint distribution tank 41, respectively. The return water inlet of chiller unit 5 is connected to the jacket outlet of the main paint tank 31 and the circulating outlet 415 of the paint distribution tank 41, respectively. During operation, chiller unit 5 delivers cooling water through the chilled water outlet to the water circulation jacket 312 and the temperature control jacket 413. The cooling water flows along the outer wall of the tank 311 in the water circulation jacket 312, absorbing the heat transferred by the paint in the tank 311. The heated cooling water flows out from the jacket outlet and returns to the return water inlet of chiller unit 5. At the same time, the cooling water flows along the outer wall of the inner tank 411 in the temperature control jacket 413, absorbing the heat of the paint in the inner tank 411. The heated cooling water flows out from the circulating outlet 415 and returns to chiller unit 5. By continuously circulating cooling water, the temperature of the paint in the main paint tank 31 and the paint distribution tank 41 is controlled within a set range to prevent the viscosity of the paint from changing due to temperature variations, which would affect the quality of the dripping paint.

[0049] In this embodiment, the chiller unit 5 is a chiller that can maintain a constant temperature.

[0050] Specifically, the second pump body is a screw pump.

[0051] Specifically, such as Figure 3 As shown, the paint supply device 4 also includes a diversion valve 45, the inlet of which is connected to the paint supply outlet 44, and the diversion valve 45 has eight outlets.

[0052] Specifically, such as Figure 1 and Figure 3 As shown, the paint distribution device 4 also includes a paint drip prevention frame 47, which is mounted on the frame 1 and located below the diversion valve 45.

[0053] In this embodiment, as Figure 3 As shown, the diversion valve 45 has one inlet channel and eight outlet channels within its valve body. The inlet channel is connected to the paint supply outlet 44 via a pipeline, and each outlet channel is connected to a different paint dripping station via an independent delivery pipeline. Each outlet channel of the diversion valve 45 is equipped with a manual flow valve, which controls the flow rate of paint to each paint dripping station by adjusting the opening of each outlet. In some embodiments, the number of outlets of the diversion valve 45 is not limited to eight; three, four, or more outlets can be provided depending on the number of paint dripping stations.

[0054] The anti-drip frame 47 is a rectangular frame structure, including a frame body and a paint collection tray disposed within the frame body. When paint drips during the switching process of the diversion valve 45 or at the pipeline connection point, the dripping paint falls into the paint collection tray of the anti-drip frame 47, preventing paint from contaminating the frame 1 and the ground. In other embodiments, the anti-drip frame 47 may also adopt a circular or other shaped frame structure.

[0055] Specifically, such as Figure 3 and Figure 6 As shown, the paint distribution device 4 also includes a liquid level display tube 6, which is vertically installed on the outer wall of the paint distribution tank 41. The upper end of the liquid level display tube 6 is connected to the upper part of the paint distribution tank 41, and the lower end of the liquid level display tube 6 is connected to the lower part of the paint distribution tank 41.

[0056] In this embodiment, as Figure 6 As shown, the liquid level display tube 6 is a transparent glass tube, connected to the paint distribution tank 41 via upper and lower connecting pipes to form a communicating vessel structure. The upper end of the liquid level display tube 6 is connected to the side wall near the top of the paint distribution tank 41 via the upper connecting pipe, and the lower end is connected to the side wall near the bottom of the paint distribution tank 41 via the lower connecting pipe. The outer surface of the liquid level display tube 6 is marked with scale markings indicating the corresponding capacity values. During operation, according to the principle of communicating vessels, the paint level in the liquid level display tube 6 is consistent with the paint level in the paint distribution tank 41. The operator can directly read the paint level in the paint distribution tank 41 by observing the liquid level position and the corresponding scale markings, without needing to open the paint distribution tank 41 to monitor changes in the remaining paint level.

[0057] In other embodiments, the level display tube 6 may also be made of a transparent plastic tube. The diameter of the level display tube 6 is determined according to the capacity of the paint dispensing tank 41.

[0058] Specifically, such as Figure 6 As shown, the paint supply device for the paint dispensing equipment also includes a temperature sensor 71, which is installed on the top of the paint dispensing tank 41. The temperature sensor 71 includes a temperature sensing rod that extends into the paint dispensing tank 41, and the temperature sensor 71 is adapted to detect the temperature of the paint liquid in the paint dispensing tank 41 through the temperature sensing rod.

[0059] Specifically, such as Figure 6 As shown, the paint supply device for the paint dripping equipment also includes a liquid level sensor 72, which is installed on the top of the paint distribution tank 41. The liquid level sensor 72 includes a liquid level probe that extends into the paint distribution tank 41. The liquid level sensor 72 is adapted to monitor the liquid level of the paint in the paint distribution tank 41 through the liquid level probe.

[0060] In this embodiment, as Figure 6 As shown, the temperature sensor 71's sensing rod extends downwards from the top into the paint inside the paint can 41. The length of the sensing rod is set to allow it to be immersed in the middle of the paint.

[0061] The level sensor 72 extends downwards from the top to near the bottom of the paint distribution tank 41. In other embodiments, the level sensor 72 may also be an ultrasonic level sensor or a radar level sensor.

[0062] Specifically, such as Figure 1 and Figure 4 As shown, the frame 1 is provided with a working chamber 11 suitable for accommodating the paint dripping station 2;

[0063] The paint supply device for the paint dripping equipment also includes an exhaust gas emission device 8, which includes a collection hood 81, an exhaust fan 82, and an exhaust pipe 83.

[0064] The collection cover 81 is fixed to the top of the frame 1 and is connected to the working chamber 11;

[0065] One end of the exhaust pipe 83 is connected to the collection hood 81, and the other end is connected to the suction port of the exhaust fan 82.

[0066] In this embodiment, as Figure 1 As shown, the working chamber 11 of the frame 1 is a closed structure, and the internal space of the working chamber 11 accommodates the paint dripping station 2 and related paint dripping equipment. The side walls of the working chamber 11 are equipped with observation windows and maintenance doors, facilitating operator observation of the paint dripping process and equipment maintenance. The collection hood 81 has a conical structure, with the bottom opening area larger than the top opening area. An exhaust fan 82 is installed outside the frame 1, and its exhaust outlet is connected to a waste gas treatment device or directly discharged outdoors. During operation, the organic waste gas generated during the paint dripping process diffuses and rises within the working chamber 11. The negative pressure generated by the exhaust fan 82 acts on the working chamber 11 through the exhaust pipe 83 and the collection hood 81, causing the waste gas to be drawn from the working chamber 11 into the collection hood 81, then transported through the exhaust pipe 83 to the exhaust fan 82 and discharged, maintaining air circulation within the working chamber 11 and reducing the concentration of harmful gases.

[0067] In this embodiment, the exhaust fan 82 can be a centrifugal fan.

[0068] The paint separating tank 41 is also equipped with a reflux port, which is connected to the main paint tank 31 via a reflux pipeline. A reflux control valve is installed on the reflux pipeline. The main paint tank 31 is equipped with a stirring device, which includes a stirring motor, a stirring shaft, and stirring blades. The stirring motor is installed on the top cover of the main paint tank 31, the stirring shaft extends downward into the interior of the main paint tank 31, and the stirring blades are fixed to the lower end of the stirring shaft. The stirring motor drives the stirring shaft and stirring blades to rotate, so that the paint in the main paint tank 31 is kept in a uniformly mixed state and the paint is prevented from settling and separating.

[0069] This embodiment also includes a pressure regulating valve 73, which is installed on the top of the paint separating tank 41. The pressure regulating valve 73 is connected to the internal space of the paint separating tank 41. The pressure regulating valve 73 is set to open a pressure value. When the pressure inside the paint separating tank 41 exceeds the set value, the pressure regulating valve 73 opens to release the pressure and prevent the pressure inside the paint separating tank 41 from being too high.

[0070] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
