Description

Technical Field

[0001] This application relates to the field of paint spraying equipment technology, and more specifically, to paint containers and spraying devices. Background Technology

[0002] Automotive painting equipment is a key piece of equipment specifically designed for surface treatment in automobile manufacturing. It is primarily used to uniformly apply paint to the surfaces of the car body, components, or interior trim. The main equipment includes manual spray guns, automatic spray guns, and painting robots. All of these devices require paint storage tanks, and the paint is delivered to the spray guns via pumps and pipelines.

[0003] Paint storage tanks use sensors to reflect the paint capacity inside the tank, and also use level gauges to verify the liquid level inside the tank. However, if the traditional transparent single tube is also blocked, it will affect the accuracy of the observation. Utility Model Content

[0004] The purpose of this application is to provide a paint container and a spraying device, wherein the paint container is provided with two liquid level observation points that corroborate each other, thereby ensuring the accuracy of liquid level observation.

[0005] To achieve the above objectives, in a first aspect, this application provides a coating container, comprising: Container body; A liquid level observation device includes a transparent tube, a first tube body, and a second tube body. The transparent tube is vertically arranged and has two ends, which are a first end and a second end, respectively. The first end is connected to the container body through the first tube body, and the second end is connected to the container body through the second tube body. The liquid level observation device is provided in two connecting tubes, one end of which is connected to the second end of one of the transparent tubes and the other end of which is connected to the second end of the other transparent tube.

[0006] In an optional embodiment, a first valve body is provided on the connecting pipe; A second valve body is provided on the first pipe body; A third valve body is provided on the second pipe body.

[0007] In an optional implementation, the second end is an opening; The liquid level observation device also includes a second sealing cap, which is detachably installed at the second end.

[0008] In an optional implementation, the first end is an opening; The liquid level observation device also includes a first sealing cap, which is detachably installed at the first end.

[0009] In an optional embodiment, the first sealing cap is provided with a piston through hole; The coating container also includes a piston cleaning component, which is slidably mounted at the piston through-hole of the first sealing cap, and slides to clean the inner wall of the transparent tube.

[0010] In an optional embodiment, the piston cleaning component includes a push-pull rod and a piston, the piston being slidably sealed to the inner wall of the transparent tube, one end of the push-pull rod being fixedly connected to the piston, and the other end of the push-pull rod extending out of the transparent tube from the piston through hole.

[0011] In an optional embodiment, the piston includes a support plate and a rubber pad, the support plate being fixedly connected to the push-pull rod, and the rubber pad being fixed to the support plate and slidingly sealingly engaging with the inner wall of the transparent tube.

[0012] In an optional embodiment, the support disc is threadedly connected to the push-pull rod.

[0013] In an optional embodiment, the piston cleaning component further includes a pressing plate, which is fixedly disposed on the push-pull rod at one end away from the piston.

[0014] Secondly, this application also provides a spraying apparatus, including a paint container as described in any of the foregoing embodiments.

[0015] This application uses a transparent tube as a vertically positioned liquid level observation device, allowing operators to directly and clearly observe the liquid level within the container without the need for complex tools or operations. Two liquid level observation devices are installed and connected at their second ends by a connecting tube, ensuring the two transparent tubes are connected and the liquid levels are consistent. Under normal use, both tubes accurately reflect the liquid level; even if one is blocked, the other will still provide a true reading, preventing inaccurate observation and improving reliability and accuracy. Simultaneously, the two transparent tubes can corroborate each other's liquid levels; discrepancies in liquid levels indicate blockage, allowing operators to respond promptly.

[0023] like Figure 1 and Figure 2 As shown, in a first aspect, embodiments of this application provide a coating container, including a container body 100, a liquid level observation device, and a connecting pipe 400.

[0024] like Figure 1 and Figure 2 As shown, the liquid level observation device includes a transparent tube 210, a first tube body 220, and a second tube body 230.

[0025] The transparent tube 210 is vertically arranged and has two ends, namely a first end 212 and a second end 214. Exemplarily, the transparent tube 210 is made of a transparent material, including but not limited to glass, resin, transparent plastic, etc.

[0026] The first end 212 is connected to the container body 100 through the first tube 220, and the second end 214 is connected to the container body 100 through the second tube 230.

[0027] For example, one end of the first tube 220 is fixedly connected to the container body 100, and the other end is fixedly connected to the first end 212; one end of the second tube 230 is fixedly connected to the container body 100, and the other end is fixedly connected to the second end 214. In another embodiment, the first tube 220 is composed of two tube segments connected by a flange, and the second tube 230 is composed of two tube segments connected by a flange.

[0028] like Figure 2 As shown, two liquid level observation devices are provided. One end of the connecting pipe 400 is connected to the second end 214 of a transparent pipe 210, and the other end is connected to the second end 214 of another transparent pipe 210.

[0029] For example, the transparent tube 210 is provided with a scale.

[0030] In this application, by setting a transparent tube 210 as a liquid level observation device, and the transparent tube 210 is set vertically, the operator can directly and clearly observe the liquid level height (such as paint) in the container body 100 without the need for complicated measuring tools or cumbersome operations, which is convenient and quick.

[0031] In this application, two liquid level observation devices are provided, and their second ends 214 are connected by a connecting pipe 400, so that the two transparent pipes 210 remain connected and the liquid levels are consistent. Under normal use, both transparent pipes 210 can accurately reflect the liquid level of the container body 100. When one transparent pipe 210 becomes blocked, due to the presence of the connecting pipe 400, the liquid between the other transparent pipe 210 and the container body 100 can still flow. Thus, the liquid level in the other transparent pipe 210 can accurately reflect the liquid level of the container body 100, avoiding the problem of inaccurate liquid level observation due to blockage of a single transparent pipe 210, and improving the reliability and accuracy of liquid level observation.

[0032] In this application, two transparent tubes 210 are provided to verify whether the liquid level is correct. When the liquid levels of the two transparent tubes 210 are different, it indicates that there is a blockage in the transparent tube 210. The operator can take timely action when he / she knows that there is a blockage, instead of waiting until the liquid in the container body 100 is used up before he / she knows that the liquid level display of the transparent tube 210 is incorrect.

[0033] like Figure 1 As shown, in one embodiment, a first valve body 500 is provided on the connecting pipe 400, and the first valve body 500 is provided on the connecting pipe 400 for controlling the opening and closing of the connecting pipe 400.

[0034] A second valve body 510 is provided on the first pipe body 220, and the second valve body 510 can control the opening and closing of the first pipe body 220.

[0035] A third valve body 520 is provided on the second pipe body 230, and the third valve body 520 can control the opening and closing of the second pipe body 230.

[0036] The first valve body 500, the second valve body 510, and the third valve body 520 are solenoid valves or manual valves.

[0037] After identifying the faulty transparent tube 210, its corresponding second valve body 510 and third valve body 520 can be closed, followed by closing the first valve body 500, thereby completely isolating the faulty transparent tube 210 from the container body 100. This isolation method can prevent the fault from further escalating, such as preventing liquid leakage from the container body 100 to other areas due to the breakage of the transparent tube 210, or preventing the blocked transparent tube 210 from affecting the liquid circulation and pressure balance of the entire system.

[0038] Isolating the faulty transparent tube 210 creates favorable conditions for its replacement. Operators can perform the replacement work in a relatively independent and safe environment without worrying about interfering with other parts of the system. Furthermore, since the system has been effectively isolated through the valve body, the replacement process does not require complex operations on the entire system, such as emptying the liquid from the container body 100, thus simplifying the replacement procedure and reducing operational difficulty and cost.

[0039] During troubleshooting of the transparent tube 210, closing the relevant valves can effectively prevent liquid leakage from the container body 100. This not only avoids contamination and damage to the surrounding environment and equipment, but also reduces the risk of operators coming into contact with hazardous liquids, ensuring a safe working environment and the health of personnel.

[0040] Since each pipe has an independent valve control, regular inspections and maintenance of each pipe and its transparent tube 210 can be conveniently performed during normal system operation. For example, the valve of a certain pipe can be closed periodically to clean and inspect that pipe and its transparent tube 210 without affecting the operation of other pipes, thus improving the efficiency and effectiveness of system maintenance.

[0041] To facilitate cleaning of the transparent tube 210, in one embodiment, the second end 214 is an opening.

[0042] like Figure 1 and Figure 2 As shown, the liquid level observation device also includes a second sealing cap 250, which is detachably installed on the second end 214. The detachable method is, for example, a threaded connection or a snap-fit ​​connection.

[0043] In this application, the second end 214 is configured as an opening and equipped with a removable second sealing cap 250, providing a convenient access point for cleaning the transparent tube 210. When it is necessary to clean the transparent tube 210, simply open the second sealing cap 250 to directly clean the inside of the transparent tube 210, simplifying the cleaning process and saving time and labor costs.

[0044] In this application, the second sealing cap 250 is detachably installed at the second end 214, and under normal operating conditions, it can tightly seal the opening, effectively preventing liquid inside the container from leaking out from the second end 214. This not only avoids liquid pollution and damage to the surrounding environment and equipment, but also reduces the risk of safety accidents caused by liquid leakage, ensuring the safety and stability of the working environment.

[0045] By installing the second sealing cap 250, the transparent tube 210 can be sealed when cleaning is not required, preventing external dust, debris, and other contaminants from entering the interior of the transparent tube 210. This protects the integrity and cleanliness of the transparent tube 210 and extends its service life. Simultaneously, it also prevents blockage or damage to the transparent tube 210 due to foreign objects entering, thus avoiding any impact on the accuracy of liquid level observation.

[0046] To make cleaning the transparent tube 210 easier, such as Figure 1 and Figure 2 As shown, in one embodiment, the first end 212 is an opening.

[0047] The liquid level observation device also includes a first sealing cap 240, which is detachably mounted on the first end 212. The detachable method is, for example, a threaded connection or a snap-fit ​​connection.

[0048] Operators can clean simultaneously from both ends 212 and 214 of the transparent tube 210. Compared to cleaning from only one end, bidirectional cleaning allows cleaning tools or cleaning media (such as cleaning fluid, airflow, etc.) to flow more effectively within the transparent tube 210, accelerating the removal of impurities and significantly shortening the overall cleaning time. For example, when cleaning the transparent tube 210 containing a large amount of sediment, simultaneous bidirectional action can more quickly disperse and discharge the sediment, improving cleaning efficiency.

[0049] In this application, the removable first sealing cap 240 allows operators to quickly open the first end 212 for operation when cleaning is required. This eliminates the need for complex disassembly or adjustment of the entire liquid level observation piece, simplifying pre-cleaning preparations and further improving cleaning efficiency. Operators can quickly enter the cleaning state, reducing waiting and preparation time.

[0050] Cleaning from both ends of the transparent tube 210 simultaneously allows for more comprehensive coverage of its internal space. Whether it's dirt and dust adhering to the tube wall or impurities settled at the bottom, the bidirectional cleaning action can remove them more thoroughly.

[0051] In order to provide a cleaning method for the transparent tube 210, such as Figure 3 As shown, in one embodiment, the first sealing cap 240 is provided with a piston through hole 242.

[0052] like Figure 1 and Figure 2 As shown, the paint container also includes a piston cleaning component. The piston cleaning component is slidably mounted at the piston through-hole 242 of the first sealing cap 240, and slides to clean the inner wall of the transparent tube 210.

[0053] During use, if it is necessary to clean the inner wall of the transparent tube 210, the second sealing cap 250 can be opened first, and then the piston cleaning component can be used to clean the inner wall of the transparent tube 210. If it is necessary to clean the piston cleaning component, the first sealing cap 240 can be opened and the piston cleaning component can be removed from the transparent tube 210.

[0054] In this application, the piston cleaning component is slidably installed at the piston through-hole 242 of the first sealing cap 240 and can slide directly on the inner wall of the transparent tube 210. This design allows the piston cleaning component to directly contact the inner wall of the transparent tube 210, effectively removing paint residue, dirt, and other impurities adhering to the inner wall through physical friction. Compared with traditional indirect cleaning methods (such as rinsing with liquid), direct contact cleaning can more thoroughly remove stubborn stains and improve the cleanliness of the transparent tube 210.

[0055] like Figure 4 As shown, in one embodiment, the piston cleaning component includes a push-pull rod 300 and a piston 310. The piston 310 is slidably sealed to the inner wall of the transparent tube 210. One end of the push-pull rod 300 is fixedly connected to the piston 310, and the other end of the push-pull rod 300 extends from the piston through hole 242 to the outside of the transparent tube 210.

[0056] Driven by the push-pull rod 300, the piston 310 can slide inside the transparent tube 210. This close cooperation allows the piston 310 to directly scrape off paint, impurities and other stains adhering to the inner wall of the transparent tube 210 during movement, achieving efficient physical cleaning. Compared with some indirect cleaning methods, it can more thoroughly remove stubborn dirt and ensure the cleanliness of the inside of the transparent tube 210.

[0057] Because the piston 310 is in close contact with the inner wall, it has a good cleaning effect on stains of different viscosities and adhesions. Whether it is a thin paint residue or a stickier, firmly attached impurity, the piston 310 can apply sufficient friction during sliding to peel it off from the inner wall, improving the adaptability and comprehensiveness of cleaning.

[0058] One end of the push-pull rod 300 extends out of the transparent tube 210, and the operator can directly control the movement of the piston 310 by holding and pushing the push-pull rod 300.

[0059] Operators can control the pushing and pulling speed and force of the push-pull rod 300 in real time based on the level of dirt inside the transparent tube 210. For example, when encountering areas with more dirt, the pushing and pulling force can be increased appropriately to enhance the cleaning effect of the piston 310; while in areas with less dirt, the pushing and pulling speed can be slowed down to avoid unnecessary wear. This real-time control capability makes the cleaning process more flexible and efficient.

[0060] To further increase the sealing contact between the piston 310 and the inner wall of the transparent tube 210, such as Figure 4 As shown, in one embodiment, the piston 310 includes a support plate 311 and a rubber pad 312. The support plate 311 is fixedly connected to the push-pull rod 300, and the fixing method is, for example, welding, gluing, snap-fitting or integral molding.

[0061] The rubber pad 312 is fixed on the support plate 311 and slides and seals with the inner wall of the transparent tube 210. The fixing method is, for example, adhesive or snap-fit.

[0062] The rubber pad 312 is soft and elastic. When it comes into contact with the inner wall of the transparent tube 210, it can adaptively deform according to the shape and surface roughness of the inner wall, filling any tiny gaps that may exist between the support plate 311 and the inner wall. This greatly increases the sealing contact between the piston 310 and the inner wall of the transparent tube 210, which helps to more effectively scrape away stubborn stains such as dried paint and scale adhering to the inner wall, making the cleaning work more thorough, ensuring the cleanliness of the inside of the transparent tube 210, and thus improving the accuracy of liquid level observation.

[0063] A tighter seal prevents dirt from escaping or remaining in the gap between the piston 310 and the inner wall during cleaning. The rubber pad 312 concentrates dirt in front of the piston 310 and pushes it out of the transparent tube 210 as the piston 310 slides, reducing the possibility of dirt residue inside the tube after cleaning and reducing the workload of secondary cleaning.

[0064] The rubber pad 312 serves as a buffer and protector. During the sliding process of the piston 310, it comes into direct contact with the inner wall of the transparent tube 210, avoiding hard friction between the support plate 311 and the inner wall, thus reducing wear on the support plate 311 and scratches on the inner wall of the transparent tube 210. This not only extends the service life of the piston 310 but also protects the transparent tube 210, reducing the maintenance and replacement costs of the equipment.

[0065] like Figure 4 As shown, in another embodiment, the support plate 311 is threadedly connected to the push-pull rod 300, which facilitates the replacement of the support plate 311 or the push-pull rod 300.

[0066] To facilitate the operation of the push-pull lever 300, such as Figure 4 As shown, in one embodiment, the piston cleaning component further includes a pressing plate 320, which is fixedly disposed on the end of the push-pull rod 300 away from the piston 310. The fixing method is, for example, welding, snap-fitting, threaded connection or integral molding.

[0067] For example, the outer diameter of the pressing plate 320 is larger than the outer diameter of the push-pull rod 300.

[0068] Secondly, embodiments of this application also provide a spraying apparatus, including a paint container as described in any of the above embodiments.

[0069] In this embodiment, the container body 100 is also equipped with other auxiliary devices, which may include liquid level monitoring and control devices, material conveying and circulation devices, safety and environmental protection devices, stirring devices, and temperature control devices, etc., which are existing technologies.

[0070] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
