Description

Technical Field

[0001] The utility model relates to the technical field of pressurized mixing barrels, and specifically relates to a paint pressurized mixing barrel. Background Technique

[0002] A paint pressure barrel is composed of a pneumatic motor, an air regulator, a safety valve, a deflation valve, a discharge port, an inner barrel and four movable wheels. The pneumatic motor of this pneumatic stirring type pressure barrel can stir by itself to keep the paint in the barrel uniform. During spraying operations, color differences will not occur due to paint precipitation. This product is not limited to paints only, and other spraying materials can also be used.

[0003] During the use of the paint pressure barrel, the pressurized mixing method is adopted for stirring, which can effectively avoid the color difference caused by precipitation. However, for some caked paints that have been placed for too long, they cannot be completely broken up, or a longer pressurized stirring time is required to ensure the crushing efficiency. If there is a caking situation, it is easy to cause blockage of the spray gun during the spraying process. Therefore, we propose a paint pressurized mixing barrel. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a paint pressurized mixing barrel, which solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A paint pressurized mixing barrel includes an outer shell and a driving mechanism. An inner pressure barrel is sleeved inside the outer shell. An air supply sleeve is fixedly sleeved outside the inner pressure barrel. A first support sleeve is fixedly installed above the air supply sleeve. A sealing ring is fixedly sleeved inside the cavity of the first support sleeve. A support spring is fixedly supported on the bottom surface of the air supply sleeve. The top end of the support spring is fixedly connected to a sealing piece. An air supply pipe is fixedly connected inside the air supply sleeve. A second support sleeve is fixedly sleeved inside the air supply pipe. A sealing ball is placed above the second support sleeve. A limiting piece is fixedly sleeved inside the air supply pipe.

[0006] Optionally, a limiting block is fixedly installed at the bottom end of the inner pressure barrel. A sealing cover is sealed on the top of the inner pressure barrel. A top cover is connected to the outside of the upper part of the outer shell through a spiral positioning structure.

[0007] Optionally, a pressure limiting valve is installed above the sealing cover. A filter element is arranged near the bottom end inside the cavity of the pressure limiting valve. The pressure limiting valve extends upward to the outside of the top cover.

[0008] Optionally, a stirring mechanism is movably sleeved inside the sealing cover. A driving mechanism is installed above the top cover. The bottom end of the driving structure extends into the inside of the stirring shaft.

[0009] Optionally, the top end of the support spring is located inside the first support sleeve, the top surface of the sealing piece is in contact with the bottom surface of the sealing ring, and the air supply pipe extends into the inner cavity of the inner pressure barrel.

[0010] Optionally, the diameter value of the sealing ball is greater than the inner diameter value of the second support sleeve. A ventilation port with a diameter value smaller than that of the sealing ball is provided inside the limiting piece. The limiting piece is located above the sealing ball, and the vertical cross-section of the air supply pipe is U-shaped.

[0011] The utility model provides a paint pressurized mixing barrel, which has the following beneficial effects:

[0012] 1. For this paint pressurized mixing barrel, through the setting of the limiting block at the bottom end of the inner pressure barrel, the stability of the connection between the inner pressure barrel and the outer casing can be ensured during use, and at the same time, the outer casing and the inner pressure barrel can be separated. The arrangement of the air supply sleeve near the bottom end outside the inner pressure barrel, by means of the cooperation of the support sleeve, the sealing ring, the sealing piece and the support spring, can limit the single-way flow of air. During the stirring process, through the cooperation of the air supply pipe, air is continuously supplied into the inner cavity of the inner pressure barrel, while ensuring the high pressure in the inner cavity of the inner pressure barrel.

[0013] 2. For this paint pressurized mixing barrel, by installing a pressure limiting valve above the sealing cover and setting a filter element at the bottom end of the pressure limiting valve, the pressure in the inner cavity of the inner pressure barrel can be ensured. The inverted U-shaped setting of the air supply pipe can prevent paint from entering the inner cavity of the air supply sleeve and affecting the elasticity of the support spring. At the same time, the cooperation of the support sleeve, the sealing ball and the limiting piece can further prevent paint from entering the inner cavity of the air supply sleeve after the pressure in the inner cavity of the outer casing is relieved.

[0020] Next, in conjunction with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a paint pressurized mixing barrel, including an outer casing 1 and a driving mechanism. An inner pressure barrel 2 is sleeved inside the outer casing 1. A gas supply sleeve 4 is fixedly sleeved outside the inner pressure barrel 2. A first support sleeve 5 is fixedly installed above the gas supply sleeve 4. The top end of the support spring 8 is located inside the first support sleeve 5. The top surface of the sealing piece 7 is in contact with the bottom surface of the sealing ring 6. The air supply pipe 9 extends into the inner cavity of the inner pressure barrel 2. The setting of the first support sleeve 5 can limit the air intake of the gas supply sleeve 4, and at the same time can block the inner cavity of the gas supply sleeve 4 and the inner cavity of the outer casing 1, enabling the air flow to be in a flowing state, effectively improving the mixing efficiency of the inner cavity of the inner pressure barrel 2. The setting of the support spring 8 mainly serves to support the sealing piece 7, and can prevent the separation of the sealing piece 7 and the sealing ring 6 during use. A sealing ring 6 is fixedly sleeved inside the inner cavity of the first support sleeve 5. The bottom surface of the gas supply sleeve 4 is fixedly supported by a support spring 8. The top end of the support spring 8 is fixedly connected to a sealing piece 7. An air supply pipe 9 is fixedly connected inside the gas supply sleeve 4. A second support sleeve 10 is fixedly sleeved inside the air supply pipe 9. A sealing ball 11 is placed above the second support sleeve 10. A limiting piece 12 is fixedly sleeved inside the air supply pipe 9. The setting of the air supply pipe 9 plays a role in preventing backflow. At the same time, the U-shaped setting can prevent the pushing material from entering the inner cavity of the gas supply sleeve 4 during use, affecting the normal rebound of the support spring 8, and can ensure the normal sealing of the sealing ring 6 and the sealing piece 7. The diameter value of the sealing ball 11 is greater than the inner diameter value of the second support sleeve 10. A ventilation port with a diameter value smaller than that of the sealing ball 11 is opened inside the limiting piece 12. The limiting piece 12 is located above the sealing ball 11. The vertical cross-section of the air supply pipe 9 is U-shaped. The inner cavity pressure of the inner pressure barrel 2 is limited by the pressure limiting valve above the sealing cover 14. Through the cooperation of the support spring 8 and the sealing piece 7 with the sealing ring 6, the inner cavity pressure of the outer casing 1 will be greater than the inner cavity pressure of the inner pressure barrel 2, ensuring the stable sealing of the sealing cover 14 and the inner pressure barrel 2. The continuous air flow can effectively improve the mixing efficiency.

[0022] A limiting block 3 is fixedly installed at the bottom end of the inner pressure barrel 2, and a sealing cover 14 is sealed on the upper part of the inner pressure barrel 2. The upper part outside the outer shell 1 is connected with a top cover 15 through a spiral positioning structure. The setting of the sealing cover 14 serves to separate the inner cavity of the outer shell 1 and the inner pressure barrel 2. At the same time, the settings of the first support sleeve 5, the plugging ring 6, the plugging piece 7 and the support spring 8 will cause a pressure difference between the inner cavity of the outer shell 1 and the inner cavity of the inner pressure barrel 2, which can ensure the sealing performance of the sealing cover 14 and the inner pressure barrel 2 and facilitate the use of the equipment. A pressure limiting valve is installed above the sealing cover 14. A filter element is arranged near the bottom end of the inner cavity of the pressure limiting valve. The pressure limiting valve extends upward to the outside of the top cover 15. The paint is sent into the inner cavity of the inner pressure barrel 2, and then the sealing cover 14 is plugged. At the same time, the top cover 15 is plugged. The driving device above the top cover 15 is controlled to drive the stirring shaft below the sealing cover 14 to stir the paint. At the same time, the air supply device is controlled to supply air from below the outer box top cover 15. A stirring mechanism is movably sleeved inside the sealing cover 14, and a driving mechanism is installed above the top cover 15. The bottom end of the driving structure extends into the inside of the stirring shaft.

[0023] In summary, when using this paint pressurizing and mixing barrel, first, the paint is sent into the inner cavity of the inner pressure barrel 2, and then the sealing cover 14 is plugged. At the same time, the top cover 15 is plugged. The driving device above the top cover 15 is controlled to drive the stirring shaft below the sealing cover 14 to stir the paint. At the same time, the air supply device is controlled to supply air from below the outer box top cover 15. After the air enters the inner cavity of the outer shell 1, it pushes the plugging piece 7 to move downward, compressing the support spring 8. Then it enters the inner cavity of the air supply sleeve 4. After the air is transported to the inner cavity of the air supply pipe 9, it will push the plugging ball 11 to move upward, and then continuously transport it into the inner cavity of the inner pressure barrel 2 through the air supply pipe 9, increasing the pressure in the inner cavity of the inner pressure barrel 2. The mixing is continuously carried out under high pressure. At the same time, the pressure in the inner cavity of the inner pressure barrel 2 is limited through the pressure limiting valve above the sealing cover 14. Through the cooperation of the support spring 8, the plugging piece 7 and the plugging ring 6, the pressure in the inner cavity of the outer shell 1 will be greater than the pressure in the inner cavity of the inner pressure barrel 2, ensuring the stable sealing of the sealing cover 14 and the inner pressure barrel 2. The continuous air flow can effectively improve the mixing efficiency, and that's it.
