Description

Technical Field

[0001] This application relates to the technical field of spraying equipment, and in particular to a release agent spraying mechanism. Background Technology

[0002] In the fabrication of concrete pipe piles, two hollow semi-cylindrical molds are typically joined together, and centrifugal molding technology is used to evenly distribute and solidify the concrete. After the pipe pile is formed, it needs to be easily removed from the mold. Therefore, before each pipe pile is fabricated, a release agent must be evenly applied to the inner surface of the mold. This is a crucial step to ensure that the pipe pile can be successfully demolded.

[0003] However, existing equipment for spraying release agents has significant drawbacks. The nozzle design of current spray guns is inadequate. Due to this nozzle construction, the release agent is sprayed in a watery state. This watery release agent is prone to splashing during spraying, failing to adhere effectively to the inner surface of the mold and resulting in significant waste, increasing production costs. Furthermore, the watery release agent is difficult to spray evenly, leading to uneven coverage in some areas and insufficient or no coverage in others. This results in inconsistent demolding performance for concrete pipe piles, with some areas experiencing difficulty in demolding and potentially damaging the pile surface, affecting pile quality and production efficiency. Therefore, developing a release agent spraying mechanism that improves spraying performance, reduces waste, and achieves uniform spraying is of significant practical importance. Utility Model Content

[0004] To improve the spraying effect of the spray gun, this application provides a mold release agent spraying mechanism.

[0005] The release agent spraying mechanism provided in this application adopts the following technical solution: A mold release agent spraying mechanism includes a spray gun body, the output end of which is fixed and connected to a connecting pipe, the output end of which is fitted with a nozzle connector, an atomizing nozzle being threaded onto the nozzle connector, and a fixing component for fixing and sealing the nozzle connector and the connecting pipe.

[0006] By adopting the above technical solution, the fixed connection design between the spray gun body and the connecting pipe ensures the stability of the release agent delivery. The sleeve fit between the connecting pipe and the nozzle connector facilitates the installation and replacement of the atomizing nozzle. The setting of the fixing component effectively enhances the fixing strength between the nozzle connector and the connecting pipe, while ensuring the sealing performance at the connection point, reducing release agent leakage. At the same time, by setting the atomizing nozzle, release agent waste can be reduced, the uniformity of release agent spraying can be improved, and the release effect can be enhanced.

[0007] Optionally, the fixing component includes a plurality of adhesive tapes, which are adhered to the connection between the nozzle connector and the connecting pipe and to the nozzle connector on the connecting pipe.

[0008] By adopting the above technical solution, this design can achieve rapid installation and disassembly, while utilizing the adhesive properties of the tape to effectively prevent leakage at the joints and ensure the stability of the spraying process.

[0009] Optionally, the fixing component includes a first sealing ring, which is fixedly connected to the inner wall of the nozzle connector. The nozzle connector is threaded with a plurality of fixing bolts, and the shank of the fixing bolts is threadedly connected to the connecting pipe.

[0010] By adopting the above technical solution, the connection between the nozzle connector and the connecting pipe is sealed by the first sealing ring, effectively preventing release agent leakage and improving the reliability of the spraying mechanism. Simultaneously, multiple fixing bolts secure the nozzle connector to the connecting pipe, ensuring the stability of the connection and reducing the risk of loosening due to vibration or pressure, thereby improving the overall structural stability and safety.

[0011] Optionally, a first annular groove is provided on the inner wall of the nozzle connector, and the first sealing ring is placed in the first annular groove.

[0012] By adopting the above technical solution, the sealing performance between the nozzle connector and the connecting pipe can be effectively improved, preventing the release agent from leaking from the connection point during high-pressure spraying. Simultaneously, the design of the first annular groove makes the installation of the first sealing ring more stable, reducing its displacement during use and thus ensuring a long-term stable sealing effect.

[0013] Optionally, the outer wall of the output end of the connecting pipe is threaded, the nozzle connector is threadedly connected to the connecting pipe, and the fixing assembly includes a receiving pipe fixedly connected to the connecting pipe. The receiving pipe is arranged around the outer wall of the connecting pipe, and the receiving pipe is provided with a locking member for restricting the rotation of the nozzle connector on the connecting pipe.

[0014] By adopting the above technical solution, the nozzle connector can be quickly installed and disassembled, improving operational efficiency. The receiving pipe is fixedly connected to the connecting pipe and set around its outer wall, further enhancing structural stability. The locking mechanism effectively restricts the rotation of the nozzle connector on the connecting pipe, ensuring the reliability and sealing of the connection and reducing leakage problems caused by loosening.

[0015] Optionally, the locking component is configured as a locking bolt, which passes through the outer wall of the receiving tube. A limiting hole is provided on the nozzle connector opposite to the shank of the locking bolt, and the shank of the locking bolt is placed in the limiting hole.

[0016] By adopting the above technical solution, a stable connection between the nozzle connector and the connecting pipe can be ensured. This design not only improves the reliability of the connection but also facilitates installation and disassembly.

[0017] Optionally, a second sealing ring is fixedly connected to the inner wall of the receiving tube.

[0018] By adopting the above technical solution, the sealing performance between the nozzle connector and the connecting pipe can be further improved, effectively preventing release agent leakage and ensuring the stability of the spraying process. This solution adds a second layer of sealing protection, based on the locking mechanism restricting nozzle connector rotation and the initial sealing provided by the first sealing ring, significantly enhancing the overall structural reliability.

[0019] Optionally, a second annular groove is formed on the inner wall of the receiving tube, and the second sealing ring is fixedly connected in the second annular groove.

[0020] By adopting the above technical solution, the sealing performance between the nozzle connector and the connecting pipe can be further improved, effectively preventing release agent leakage and ensuring the stability and reliability of the spraying process. This design uses a dedicated second annular groove on the inner wall of the receiving pipe to install the second sealing ring, making the sealing ring's position more precise and less prone to displacement or detachment, thereby improving the overall sealing effect and service life of the structure.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. It effectively enhances the fixing strength between the nozzle connector and the connecting pipe, while ensuring the sealing performance at the connection between the two, reducing the leakage of release agent. At the same time, by setting the atomizing nozzle, it can reduce the waste of release agent, improve the uniformity of release agent spraying and improve the release effect. 2. This design allows for quick installation and removal of the nozzle connector, improving operational efficiency. The receiving pipe is fixedly connected to the connecting pipe and surrounds its outer wall, further enhancing structural stability. The locking mechanism effectively restricts the rotation of the nozzle connector on the connecting pipe, ensuring reliable and airtight connections and reducing leakage problems caused by loosening. 3. By setting a special second annular groove on the inner wall of the receiving tube to install the second sealing ring, the position of the sealing ring is more accurate and less prone to displacement or falling off, thereby improving the sealing effect and service life of the overall structure.
