Description

Technical Field

[0001] This utility model relates to the technical field of spraying equipment components, and in particular to a self-cleaning spraying pipe structure for spraying equipment. Background Technology

[0002] Spraying equipment is a tool used to evenly coat the surface of an object with paint. It mainly consists of a paint supply system, a spray gun, and a spray pipe. The paint supply system is responsible for storing and transporting paint. Pressure tanks or pumps can provide power to make the paint flow to the spray gun. The spray gun is a key component that can atomize the paint and spray it onto the target object. It has internal structures such as nozzles to control the spray shape and flow rate of the paint.

[0003] The spray pipe connects the paint supply system and the spray gun, serving to transport the paint. The simple structure of traditional spray pipes makes cleaning inconvenient: Traditional spray pipes are relatively simple, typically consisting of a hollow tube. When paint clogs the tube, disassembly is necessary for cleaning, which is very troublesome. First, disassembly is cumbersome, requiring tools to loosen connections and careful handling to avoid damaging the tube or other components. Second, frequent disassembly affects the tightness of the spray equipment's connections, potentially leading to paint leaks during subsequent use. Furthermore, cleaning the disassembled tube is complex, requiring reinstallation and adjustment, which is time-consuming and reduces work efficiency. To address these issues, we propose a self-cleaning spray pipe structure for spray equipment. Utility Model Content

[0004] The main objective of this invention is to provide a self-cleaning spray pipe structure for a spraying device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, a self-cleaning spraying equipment spray pipe structure includes an equipment connecting pipe 1 and a spray gun connecting pipe 3. The equipment connecting pipe 1 and the spray gun connecting pipe 3 are respectively threaded to the equipment mounting end and the spray gun. A converter 2 is provided on both the equipment connecting pipe 1 and the spray gun connecting pipe 3. A top cover 7 is provided on the converter 2. A first valve 4 and a fourth valve 10 are respectively provided on the equipment connecting pipe 1 and the spray gun connecting pipe 3. A drive mechanism for driving the movement of the blocked paint is provided on the spray gun connecting pipe 3. The drive mechanism includes a cleaning pipe 5 provided on the spray gun connecting pipe 3. A second valve 6 is connected to the cleaning pipe 5. A second drain pipe 12 is connected to the lower end of the converter 2. A fifth valve 13 is provided on the second drain pipe 12.

[0023] The transfer unit 2 is equipped with a filter mechanism for filtering coatings. The filter mechanism includes a filter screen 11 installed in the transfer unit 2. The top cover 7 is threadedly connected to the transfer unit 2 and is transparent.

[0024] In this utility model, the top cover 7 is connected to a first drain pipe 8, and the first drain pipe 8 is equipped with a third valve 9. The ends of the cleaning pipe 5, the first drain pipe 8, and the second drain pipe 12 are flange rings, and the through holes on them are not shown in the figure. The filter screen 11 can be cleaned by the gas filled into the first drain pipe 8.

[0025] In this utility model, a heating sleeve 14 is provided on the side wall of the spray gun connecting pipe 3, a heating wire 15 is provided inside the heating sleeve 14, an mounting plate 19 is provided on the side wall of the heating sleeve 14, and a controller 21 is provided on the side wall of the mounting plate 19. The part of the spray gun connecting pipe 3 inside the heating sleeve 14 is a metal pipe, and the rest is a flexible hose. The paint near the spray gun can be heated by heating the air inside the heating sleeve 14, which avoids the paint cooling down during the long pipeline transportation process, thereby ensuring that the temperature of the paint sprayed from the spray gun meets the requirements.

[0026] In this invention, mounting tubes 16 are provided through both sides of the heating jacket 14. A fan 17 is provided inside one of the mounting tubes 16. A temperature sensor 20 is provided on the side wall of the mounting plate 19. The temperature inside the heating jacket 14 can be detected by the temperature sensor 20. However, when the temperature inside the heating jacket 14 is too high, the fan 17 is turned on to dissipate heat from the heating jacket 14, thereby maintaining a constant temperature of the coating and preventing the coating temperature from becoming too high.

[0027] In this utility model, the side wall of the mounting tube 16 is provided with a dustproof mesh cover 18 to prevent dust from accumulating on the heating wire 15 and affecting the heating efficiency. The dustproof mesh cover 18 is threadedly connected to the mounting tube 16, making it easy to remove the dustproof mesh cover 18 and easy to clean the dustproof mesh cover 18.

[0028] It should be noted that this utility model is a self-cleaning spraying equipment spray pipe structure. First, the equipment connecting pipe 1 and the spray gun connecting pipe 3 are connected to the installation end of the spraying equipment and the spray gun, respectively. The cleaning pipe 5 is connected to an external compressor or inert gas storage device through a pipeline. The first sewage pipe 8 and the second sewage pipe 12 are connected to an external waste collection device. When the paint passes through the spraying pipe, it first enters the transfer device 2. The filter screen 11 in the transfer device 2 filters the paint and filters out large particles of impurities to avoid clogging the nozzle. The paint may be contaminated during storage, such as by the presence of dust, rust and other impurities, or by insufficient mixing of the paint during the mixing process, resulting in the formation of larger particles from pigment agglomeration.

[0029] After prolonged use, the spray pipe can be cleaned by closing the first valve 4 and the fourth valve 10, and opening the fifth valve 13, the second valve 6 and the external compressor. Compressed air will quickly fill the spray gun connecting pipe 3 with gas. The compressed gas can generate a certain pressure, causing the remaining paint in the pipe to be discharged from the second drain pipe 12.

[0030] After the sewage discharge is completed, the third valve 9 can be opened and the fifth valve 13 can be closed. The compressed gas will flush out the impurities on the filter screen 11, which can make the filter screen 11 automatically clean.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
