Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a quick-attachment device for profile spraying workpieces. Background Technology

[0002] In the production process of profile spraying, the surface needs to be fully treated. To improve spraying efficiency, electrostatic adsorption spraying is mainly used. To ensure uniform coating on the profile surface, a clamping and hanging structure is required to move the profile past the spray nozzle. Currently, the hanging methods are mainly divided into horizontal hanging and vertical hanging. Horizontal hanging refers to fixing the profile at both ends, while vertical hanging involves clamping and hanging one end of the profile. Because the profile is hollow, horizontal hanging only requires the hanging structure to be inserted into both ends, while vertical hanging requires opening hanging holes at the ends of the profile, adding an extra step.

[0003] Traditional horizontal hanging methods only involve mounting the profile at both ends. For ease of installation, one end of the profile is typically inserted into one end of the hanger and then pulled inward. The profile is then pushed back into the hanger at the other end, and finally positioned between the two hangers. Subsequently, the profile moves along a chain conveyor and is sprayed through a nozzle to achieve the desired coating process on its outer surface.

[0004] Current research has found that horizontal conveying often causes vibration during the movement of profiles. This vibration can cause the profiles to fall off the hangers, posing a safety hazard. It also affects the rotation efficiency of the profiles, thereby impacting overall production efficiency. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] See Figures 1-3 As shown, this utility model provides a quick-attachment device for profile spraying workpieces, including: The sliding cylinder 1 is horizontally positioned and used for insertion during profile installation. Its interior is a hollow cylindrical structure to facilitate the installation of the sliding rod 9. The sliding cylinder 1 contains a horizontally movable sliding rod 9, whose diameter is slightly smaller than that of the sliding cylinder 1. During installation, the rod can be inserted into the sliding cylinder 1 for smooth movement, preventing excessive size differences that could cause the rod to wobble inside the cylinder and affect the stability of subsequent profile positioning processes, thus reducing noise during production. One end of the sliding rod 9 can protrude from the sliding cylinder 1 for insertion into the profile end for positioning. By adjusting the relative position of the sliding rod 9 within the sliding cylinder 1, the insertion of the sliding rod 9 into the profile end can be controlled, thereby meeting the requirements of the profile installation process. The base 2 is located at one end of the sliding cylinder 1 and is used to install and fix it with the locking nut 4. The base 2 is fixedly connected to the sliding cylinder 1 and is used to provide support for the installation of the sliding cylinder 1. At present, the profile is usually moved synchronously by a motor combined with gears to drive the chain, thereby realizing the transfer of the profile. In the current method, a set of symmetrical synchronous chains is usually set at each end of the profile. A single motor combined with a reduction mechanism drives the two chains to move synchronously, so that the base 2 and the sliding cylinder 1 hanging on the chain can move synchronously. Since the base 2 is fixed to the chain conveyor belt by the locking nut 4, it can drive the profile to move synchronously during the movement of the chain, thus realizing the transfer requirements.

[0019] In another embodiment, a connecting protrusion 3 is provided on the side wall of the base 2. The outer surface of the connecting protrusion 3 is provided with a thread that mates with the locking nut 4. The size of the connecting protrusion 3 matches the size of the chain link that makes up the drive chain. By adding an opening on the chain link, the connecting protrusion 3 can be inserted into the chain link and tightened with the fixing nut 7, thereby realizing the connection between the chain link and the base 2. In this way, the base 2 and the sliding cylinder 1 can move synchronously during the movement of the motor-driven chain, thereby realizing the position adjustment of the hanging device to facilitate the spraying process of the profile surface.

[0020] In another embodiment, the base 2 is a rectangular plate or an ellipse. The rounded edges of the ellipse make it less likely to rub against the surface of the workpiece, which can improve product quality.

[0021] In another embodiment, the connecting protrusion 3 on the base 2 and the central axis of the sliding cylinder 1 are arranged in a centrally symmetrical manner. This centrally symmetrical arrangement ensures the versatility of the hanging device in production. As can be seen from the usage view in the figure, the hanging device set on the symmetrically arranged chain also has a symmetrical structure, but the sliding cylinders 1 on both sides are at different heights. This design is because, in traditional hanging devices, the support structures for both ends of the profile are horizontally arranged. When installing the hanging device, to ensure ease of installation, the distance between the support structures is usually smaller than the actual length of the hanging device. This is not affected when the hanging device moves smoothly, but as the moving distance increases, the number of vibrations increases, often causing the profile to move closer to one side of the hanging device, which can lead to the other end of the profile detaching from the hanging device, affecting… This can disrupt normal production and, in severe cases, cause equipment malfunctions and shutdowns. To address these issues, this solution employs a rectangular base 2 design, combined with a centrally symmetrically arranged sliding cylinder 1 and connecting protrusion 3. This design facilitates the flipping of the mounting brackets during installation, resulting in different heights of the sliding cylinders 1 at both ends of the profile. This causes the profile to tilt towards one side of the sliding cylinder 1 under gravity, reducing swaying during profile movement. The end of the sliding rod 9 is provided with an extension section 10, and a through hole is provided on the end face of the sliding cylinder 1 for the extension section 10 to pass through. The extension section 10, located inside the sliding rod 9, can pass through the sliding cylinder 1 and extend into the profile for positioning, preventing the profile from detaching from the sliding cylinder 1 and improving the stability of the profile during the process.

[0022] In another embodiment, a limiting ring 5 is formed on the side wall of the sliding rod 9, and a spring 6 that cooperates with the limiting ring 5 is fitted on the outer wall of the sliding rod 9. The design of the limiting ring 5 allows it to cooperate with the spring 6. Under normal working conditions, the spring 6 can push the limiting ring 5 to move outward, so that the extension section 10 always remains extended from the inside of the sliding cylinder 1, shortening the distance between the two hanging devices to be less than the length of the profile, thus preventing the profile from falling off during transportation and causing safety hazards.

[0023] In another embodiment, a detachable pull rod 8 is provided on the sliding rod 9, and a guide groove 11 for the pull rod 8 to move is provided on the outer wall of the sliding cylinder 1. When installing the pull rod 8, the sliding rod 9 can be inserted into the sliding cylinder 1 first, the pull rod 8 can be inserted into the guide groove 11 and then screwed into the sliding rod 9. The sliding rod 9 can be controlled to move inside the sliding cylinder 1 by the pull rod 8. Then, the section of the sliding cylinder 1 near the base 2 is sealed by the fixing nut 7 to prevent the spring 6 fitted on the outer wall of the sliding rod 9 from falling off. During installation, the worker adjusts the position of the sliding rod 9 inside the sliding cylinder 1 to facilitate the installation of the profile. In addition, in the daily working state, the spring 6 can cooperate with the limiting ring 5 to push the sliding rod 9 and the extension section 10 to move inside the sliding cylinder 1, thereby always keeping the extension section 10 extended into the profile, preventing the profile from falling off the hanging device during the hoisting and moving process, and ensuring the safety of the profile production process.

[0024] During installation, the operator symmetrically fixes the base 2 to the side wall of the chain. To ensure the stability of the profile during transportation, the sliding cylinders 1 at both ends of the profile need to be at different heights. In use, the operator places the profile to be hung horizontally, inserts one end of the profile into one of the sliding cylinders 1, ensuring it is flush against the end face of the profile, and then pulls back the lever 8 on the other end of the hanging device. This pull lever 8 moves the sliding rod 9, causing the extension section 10 to retract into the sliding cylinder 1. At this point, the other end of the profile can be aligned with the sliding cylinder 1 on the hanging device. After releasing the lever 8, the spring 6 inside the sliding cylinder 1 pushes the limiting ring 5, causing the sliding rod 9 to move, allowing the extension section 10 to be inserted into the profile, thus achieving the hanging of the profile and preventing the profile from slipping off the device during transportation. The profile is detached from the device to ensure safety during the profile production process. The profile then moves along the chain past the spray nozzle, where it undergoes electrostatic adsorption for surface coating. After baking and shaping, it is exported. To remove the profile, the operator simply holds one end and pushes it forward, causing the end face to abut against the base 2 of the other end's hanging device. Then, the operator pulls the lever 8 inward, causing its extension 10 to retract from the profile into the sliding cylinder 1. The profile is then moved downward to detach from the sliding cylinder 1. Finally, the profile is pulled backward to remove it from the other end's hanging device, completing the profile detachment process. The hanging device not only simplifies operation and increases installation efficiency but also allows for rapid profile mounting and positioning, ensuring safety during production.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
