Description

Technical Field

[0001] This utility model relates to the technical fields of spray painting machine technology and inkjet marking industry, specifically an integrated spray painting machine. Background Technology

[0002] With the development of industrial manufacturing technology and the increasing demands of consumers for product appearance quality, surface treatment technology is playing an increasingly important role in the manufacturing industry. The rapid development of industries such as automobiles, in particular, has placed higher requirements on the appearance and marking of automotive parts. Currently, the entire marking industry cannot meet the online printing requirements for automotive rubber hoses and air conditioning pipes. Because these products require vulcanization, demolding, and cleaning processes, markings are only manually applied at the final stage of the production line, significantly increasing labor costs and slowing down production. Against this backdrop, we developed a spraying machine for the first time for use on rubber hoses, protecting the integrity of the markings during cleaning. A spraying machine is a mechanical device used to uniformly spray liquid or powdered materials (such as paint, coatings, and varnishes) onto the surface of an object. It atomizes the coating using different techniques and sprays it at high speed onto the surface to be treated, forming a uniform and smooth coating. Spraying machines are widely used in construction, automobile manufacturing, furniture production, and metal processing, effectively solving adhesion and surface protection issues.

[0003] Traditional spray painting machines are typically single-function and scattered, which brings many inconveniences to different application scenarios. In addition, during the use of spray painting machines, factors such as temperature changes, solvent evaporation, and the influence of additives can cause changes in the viscosity of the paint, thereby affecting the quality and efficiency of the spraying operation. At the same time, traditional spray painting machines cannot continuously stir the paint during use, resulting in paint sedimentation and making it difficult to ensure the uniformity of paint viscosity.

[0004] In response to the aforementioned problems, we have improved the internal circuitry and gas flow of the spraying machine by developing and adjusting its internal components. Based on the characteristics of rubber hoses, we have successfully debugged a spraying machine that can achieve both small-volume, micro-atomization and continuous, stable spraying, completely solving the long-standing challenge of labeling in the rubber products industry. This machine can be integrated into the entire production line, improving production efficiency and significantly reducing labor costs. Therefore, we propose a highly integrated spraying machine and its usage method. Utility Model Content

[0013] (1) In this solution, by adjusting the internal device of the spraying machine to improve the circuit and gas flow, and specifically according to the characteristics of the rubber hose, the spraying machine can be used to ensure that it can spray small amount of micro-atomized material and continuously and stably, which completely solves the long-standing problem of labeling in the rubber products industry. It is integrated into the entire production line device, which can improve production efficiency and reduce labor costs. By setting a stirring mechanism and a multi-stage pressure valve assembly in the spraying machine box, the problem of unstable flow caused by changes in paint viscosity in traditional spraying machines is effectively solved. Specifically, the spiral rod and stirring head driven by the stepper motor can continuously stir the paint in the feed cylinder to prevent sedimentation and ensure that the paint viscosity is uniform. At the same time, the design of the arc scraper and spiral cylinder not only further ensures the uniformity of the paint, but also automatically removes the adhering material on the inner wall to avoid blockage.

This design significantly improves the quality of the spraying operation, makes the coating more uniform and smooth, reduces defects caused by flow fluctuations, achieves micro-atomization and continuous stability of spraying, and provides a basis for the spraying machine to cooperate with the inkjet printer in the rubber products industry. After the inkjet printer marks the rubber products, the spraying machine successfully sprays the protective film to achieve complete and clear marking, realizing the first successful application of the spraying machine in the marking industry.

Figures 1 to 6 As will be clearly shown in the detailed description of the embodiments, all structural contents mentioned in the following embodiments are with reference to the accompanying drawings.

[0023] Example 1: This example provides an integrated spraying machine, such as... Figure 1 and Figure 3 As shown, the spraying machine includes a spraying machine housing 1 and a spray gun 8.

An observation window 5 is provided on the upper cover 11. An auxiliary handle 6 is fixedly connected to the upper surface of the upper cover 11. A door panel 2 is provided on the front side of the spraying machine housing 1. A lock 3 is provided on the door panel 2.

[0024] When using the spray painting machine, the integrated spray painting machine has a spray painting machine housing 1. The top of the spray painting machine housing 1 is equipped with a control panel 4 for operation settings. The top cover 11 is hinged to the housing, making it easy to open for inspection or maintenance of internal components. The handles 9 on both sides make it easy to move the machine. The left side has a switch button 7 and a charging interface 10 for power management and starting the equipment. The pressure regulating valve 14 on the rear side allows users to adjust the spraying pressure. At the same time, multiple heat dissipation holes 12 ensure that the machine can effectively dissipate heat during operation. The door panel 2 is located on the front side and has a lock 3 to protect the safety of the internal parts. The user turns on the equipment with the switch button 7 and uses the control panel 4 to set the spraying parameters. The pressure regulating valve 14 can be adjusted to a suitable spraying pressure as needed. The observation window 5 allows the user to check the internal condition without opening the top cover 11. When the machine is running, the heat dissipation holes 12 help maintain a suitable working temperature and prevent overheating. After the work is completed, the door panel 2 can be opened for cleaning and maintenance.

[0025] Example 2, based on Example 1, is improved in that, as follows: Figure 2 , Figure 3 and Figure 4 As shown, a feed cylinder 42 is installed inside the spraying machine housing 1. A sleeve 23 is installed on the outside of the feed cylinder 42. A stirring mechanism is installed inside the feed cylinder 42. A feeding mechanism is installed on the outside of the sleeve 23. A first pressure valve 43, a second pressure valve 26, and a third pressure valve 18 are installed on the top of the spraying machine housing 1. The first pressure valve 43, the second pressure valve 26, and the third pressure valve 18 are all fixedly installed in the upper part of the spraying machine housing 1. A first connecting pipe 19 is fixedly connected to the inner wall of the first pressure valve 43. One end of the first connecting pipe 19 is connected to... The pressure regulating valve 14 is fixedly connected. The other end of the first connecting pipe 19 is disposed in the feed cylinder 42 through the first through hole 25. The inner wall of the second pressure valve 26 is fixedly connected to the second connecting pipe 16. One end of the second connecting pipe 16 passes through the sleeve 23 and is disposed in the feed cylinder 42. The other end of the second connecting pipe 16 is fixedly connected to the spray gun 8 through the first through hole 25. One end of the third pressure valve 18 is fixedly connected to the third connecting pipe 15. The other end of the third connecting pipe 15 is fixedly connected to the spray gun 8 through the first through hole 25.

[0026] When using the spraying machine, three pressure valve assemblies are configured on the top, which are respectively used to connect the pressure regulating valve 14, the spray gun 8, and the feed cylinder 42 to control the pressure of different parts. The feed cylinder 42 stores the material to be sprayed, and the stirring mechanism ensures that the material is mixed evenly. The first pressure valve assembly 43 transmits the regulated pressure to the feed cylinder 42. The second pressure valve assembly 26 is responsible for pushing the material from the feed cylinder 42 to the spray gun 8. The third pressure valve assembly 18 may be used to assist in controlling the pressure at the spray gun 8. This design makes the spraying process more stable, improves the consistency and quality of the spraying effect, achieves micro-atomization and continuous stability of spraying, and provides a foundation for the spraying machine to be used in conjunction with the inkjet printer in the rubber products industry. After the inkjet printer marks the rubber products, the spraying machine successfully sprays a protective film to achieve complete and clear markings, realizing the first successful application of the spraying machine in the marking industry.

[0027] Example 3, based on Example 2, is improved in that, as follows: Figure 3 and Figure 5 As shown, the feeding mechanism includes a feeding pipe 22, a closed feeding hopper 21, and a quick connector 44. One end of the feeding pipe 22 passes through the sleeve 23 and communicates with the feeding cylinder 42. The other end of the feeding pipe 22 is fixedly connected to the closed feeding hopper 21. The bottom end of the quick connector 44 is fixedly connected to the top end of the closed feeding hopper 21. A liquid level sensor 24 is provided on the lower outer side of the feeding cylinder 42.

[0028] When using the spraying machine, the feed pipe 22, the closed feed hopper 21, and the quick connector 44 together form the path for the paint to enter the feed cylinder 42. The quick connector 44 allows the user to quickly connect or disconnect the closed feed hopper 21, thus simplifying the process of adding new paint. The closed feed hopper 21 ensures that the paint will not leak during the transfer process, keeping the working environment clean. The feed pipe 22 is directly connected to the feed cylinder 42, ensuring that the paint can flow smoothly. The liquid level sensor 24 can remind the user to add spray paint. By developing and adjusting the internal device of the spraying machine to improve the circuit and gas flow, and specifically based on the characteristics of the rubber hose, the spraying machine can ensure that it can spray small amounts of micro-atomized paint continuously and stably, and completely solve the long-standing problem of labeling in the rubber products industry. It can be integrated into the entire production line, which can improve production efficiency and significantly reduce labor costs.

[0029] Example 4, based on Example 3, is improved in that, as follows: Figure 5As shown, a housing 20 is fixedly connected to the upper surface of the sleeve 23. A stepper motor 27 is fixedly connected to the inner wall of the housing 20. Two sealed bearings 35 are fixedly connected to the inner wall of the sleeve 23. A drive shaft 34 and a spiral shaft 28 are fixedly connected to the inner rings of the two sealed bearings 35 respectively. The bottom end of the drive shaft 34 is fixedly connected to the top end of the spiral shaft 28. The output end of the stepper motor 27 is fixedly connected to the top end of the drive shaft 34. A spiral groove 30 is opened on the inner wall of the feed cylinder 42. Two limiting rings 31 and a stirring head 33 are fixedly connected to the outer surface of the spiral shaft 28 respectively. Four bottom scrapers 32 are fixedly connected to the outer surface of the stirring head 33.

[0030] When using the spraying machine, the stepper motor 27 drives the transmission shaft 34 to rotate stably inside one of the sealed bearings 35. The transmission shaft 34 drives the spiral shaft 28 to rotate stably inside the other sealed bearing 35. The spiral shaft 28 can directly drive the bottom stirring head 33 to rotate. The stirring head 33 can stir the paint inside the feed cylinder 42. The bottom scraper 32 set on the outside of the stirring head 33 can stir the paint at the bottom of the feed cylinder 42 and at the same time scrape off the paint adhering to the bottom, preventing the paint from adhering to the inner wall of the feed cylinder 42 and facilitating the spraying of the paint.

[0031] Example 5, based on Example 4, is improved in that, as follows: Figure 6 As shown, each bottom scraper 32 has four first flow ports 45 on its outer surface. The outer surface of the spiral shaft 28 is spirally connected to a spiral cylinder 29. Two connecting blocks 17 are fixedly connected to the outer surface of the spiral cylinder 29. Nitrile rubber plates 37 are fixedly connected to the two connecting blocks 17 on their respective sides away from each other. Arc-shaped scrapers 36 are fixedly connected to the two nitrile rubber plates 37 on their respective sides away from each other. Two baffle plates 39 and two scraping plates 40 are fixedly connected to the outer surface of each arc-shaped scraper 36. Four arc-shaped balls 41 are fixedly connected to the outer surface of each arc-shaped scraper 36. Five second flow ports 38 are opened on the outer surface of each arc-shaped ball 41. The outer surface of each arc-shaped ball 41 is slidably connected to the inside of the spiral groove 30.

[0032] When using the spraying machine, the rotation of the spiral shaft 28 also drives the spiral cylinder 29 to rotate. The connecting block 17 on the spiral cylinder 29 and its connected nitrile rubber plate 37 and arc-shaped scraper 36 also rotate accordingly. The arc-shaped ball 41 on the outer surface of the arc-shaped scraper 36 slides in the spiral groove 30 on the inner wall of the feed cylinder 42, so that the arc-shaped scraper 36 can closely fit the inner wall of the feed cylinder 42. The baffle plate 39 and scraper 40 fixed on its outer surface further scrape and clean the paint on the inner wall of the feed cylinder 42. The five second flow ports 38 also help the paint flow, ensuring that the paint is fully stirred and flows smoothly in the feed cylinder 42 and that the inner wall of the feed cylinder 42 is clean. This ensures that the entire equipment can work stably and efficiently, spraying the paint evenly to meet the usage requirements.

[0033] Working Principle: In use, the integrated spray painting machine has a spray painting machine housing 1. A control panel 4 is located on top of the housing 1 for operation settings. The top cover 11 is hinged to the housing for easy opening to inspect or maintain internal components. Handles 9 on both sides facilitate machine movement. A power switch 7 and charging port 10 are located on the left side for power management and equipment startup. A pressure regulating valve 14 at the rear allows users to adjust the spraying pressure. Multiple ventilation holes 12 ensure effective heat dissipation during operation. The door panel 2 is located on the front and is secured with a lock 3 to protect internal components. The user starts the equipment using the power switch 7 and sets the spraying parameters using the control panel 4. The pressure regulating valve 14 can be adjusted to the appropriate spraying pressure as needed. An observation window 5 allows the user to view the spraying process. The internal structure allows for easy access without opening the top cover 11. During machine operation, the ventilation holes 12 help maintain a suitable working temperature and prevent overheating. After work is completed, cleaning and maintenance can be performed by opening the door panel 2. The inner wall of the spraying machine housing 1 is equipped with three pressure valve assemblies, which are respectively connected to the pressure regulating valve 14, the spray gun 8, and the feed cylinder 42 to control the pressure of different parts. The feed cylinder 42 stores the material to be sprayed, and the stirring mechanism ensures uniform mixing of the material. The first pressure valve 43 transmits the regulated pressure to the feed cylinder 42, the second pressure valve 26 pushes the material from the feed cylinder 42 to the spray gun 8, and the third pressure valve 18 may be used to assist in controlling the pressure at the spray gun 8. This design makes the spraying process more stable and improves the consistency of the spraying effect. This system effectively solves the problems of unclear and insecure markings on automotive hoses and rubber products in the market. It also addresses the issue that factors such as temperature changes, solvent evaporation, and additives can cause variations in paint viscosity during spraying, thus affecting the quality and efficiency of the spraying operation. The feed pipe 22, closed feed hopper 21, and quick connector 44 together form the path for paint to enter the feed cylinder 42. The quick connector 44 allows users to quickly connect or disconnect the closed feed hopper 21, simplifying the process of adding new paint. The closed feed hopper 21 ensures that paint does not leak during transfer, maintaining a clean working environment. The feed pipe 22 connects directly to the feed cylinder 42, ensuring smooth paint flow. A liquid level sensor is also included. Device 24 can remind the user to add spray paint. When the stirring mechanism is working, the stepper motor 27 drives the transmission shaft 34 to rotate stably inside one of the sealed bearings 35. The transmission shaft 34 drives the screw shaft 28 to rotate stably inside the other sealed bearing 35. The screw shaft 28 can directly drive the bottom stirring head 33 to rotate. The stirring head 33 can fully stir the paint inside the feed cylinder 42 to ensure the uniformity of the paint. At the same time, the bottom scraper 32 on the outside of the stirring head 33 not only helps to stir the paint, but the four first flow ports 45 on its outer surface can also promote the flow of paint during the stirring process. In addition, the bottom scraper 32 can scrape off the paint adhering to the bottom of the feed cylinder 42, effectively preventing the paint from adhering to the inner wall of the feed cylinder 42.To ensure smooth coating flow from the feed cylinder 42, the rotation of the spiral shaft 28 also drives the spiral cylinder 29 to rotate. The connecting block 17 on the spiral cylinder 29, along with its connected nitrile rubber plate 37 and arc-shaped scraper 36, also rotate. The arc-shaped ball 41 on the outer surface of the arc-shaped scraper 36 slides within the spiral groove 30 on the inner wall of the feed cylinder 42, allowing the arc-shaped scraper 36 to closely adhere to the inner wall of the feed cylinder 42. The baffle plate 39 and scraper plate 40 fixed to its outer surface further scrape and clean the coating on the inner wall of the feed cylinder 42. The five secondary flow ports 38 also facilitate coating flow. Through this coordinated operation, the coating is fully stirred and flows smoothly within the feed cylinder 42, and the inner wall of the feed cylinder 42 remains clean, ensuring the entire equipment operates stably and efficiently. The material is sprayed evenly to meet usage requirements, effectively ensuring stable spraying of the coating through the spray gun 8. This further stabilizes the coating flow, achieving micro-atomization and continuous stability, laying the foundation for the spraying machine to work in conjunction with inkjet printers in the rubber products industry. After the inkjet printer marks the rubber products, the spraying machine successfully applies a protective film, achieving complete and clear markings. This marks the first successful application of the spraying machine in the marking industry. Furthermore, through research and development and adjustments to the internal components, the spraying machine's circuitry and gas flow have been improved. Specifically tailored to the characteristics of rubber hoses, this ensures that the spraying machine can achieve both small-volume, micro-atomization spraying and continuous stability, completely solving the long-standing challenge of marking in the rubber products industry. Integrated into the entire production line, it improves production efficiency and significantly reduces labor costs.
