Description

Technical Field

[0001] This utility model relates to the transportation of coiled wire, specifically to a spray lubrication and negative pressure demisting device for coiled wire. Background Technology

[0002] After the wire is coiled, it needs to be bundled before being delivered to the user. During bundling, the coils are subjected to pressure, which can cause defects such as crushing marks and surface abrasions. These surface problems directly affect the quality of the coils leaving the factory. To solve this problem, a protective coating of lubricant can be applied to the surface of the coils. However, using this method also requires addressing environmental and safety issues, such as preventing the lubricant from being released into the air. Utility Model Content

[0003] This utility model provides a steel wire coil spray lubrication and negative pressure demisting device. The steel wire coil is suspended on a C-shaped hanger. The steel wire coil spray lubrication and negative pressure demisting device includes a sliding sealing cover, a three-dimensional spray mechanism and a negative pressure demisting mechanism.

[0004] The sliding seal cover is slidably installed on the ground rail. The sliding seal cover slides on the ground rail along the axial direction of the wire coil. The top of the sliding seal cover is provided with strip-shaped openings distributed along the sliding direction. The sliding seal cover slides towards the C-shaped lifting device so that the wire coil enters the sliding seal cover. The end of the sliding seal cover away from the C-shaped lifting device is provided with a negative pressure connection port.

[0005] The three-dimensional spraying mechanism includes an inner ring spraying mechanism and an outer ring spraying mechanism. The inner ring spraying mechanism and the outer ring spraying mechanism are connected to the lubricating fluid supply system. The inner ring spraying mechanism is provided with a central tube that is axially fixed inside the sliding sealing cover. Multiple first spray nozzles are arranged around the central tube. The outer ring spraying mechanism is provided with multiple second spray nozzles that are circumferentially arranged on the inner wall of the sliding sealing cover. The first spray nozzles and the second spray nozzles are respectively facing the inner ring and the outer ring of the wire coil.

[0006] The sliding sealing cover is connected to a negative pressure demisting mechanism, which includes a corrugated expansion pipe, a steam-water separator, and a centrifugal fan. One end of the corrugated expansion pipe is connected to the negative pressure connection port, and the other end is connected to the centrifugal fan through the steam-water separator.

[0007] The sliding sealing cover slides horizontally, allowing the wire coil of the C-shaped lifting device to enter the sliding sealing cover. During the sliding process, a three-dimensional spraying mechanism sprays lubricant onto the inner and outer rings of the wire coil, and a negative pressure demisting mechanism creates negative pressure inside the sliding sealing cover to extract the floating atomized lubricant.

[0008] Furthermore, both the first and second spray nozzles are dual-flow nozzles.

[0009] Furthermore, the sliding sealing cover is arched, with an opening at one end near the C-shaped lifting device and a closed end at the other.

[0010] The sliding sealing cover has a drooping sealing plate and rollers on both sides of the bottom. The rollers are rolled on the ground rail, and the flexible drooping sealing plate is vertically fixed to the inner side of the sliding sealing cover. The drooping sealing plate separates the rollers and the ground rail from the internal space of the sliding sealing cover.

[0011] Furthermore, the negative pressure connection port is connected to the corrugated expansion pipe via an elbow flange.

[0012] Furthermore, the C-shaped spreader is slidably installed on the gantry, and a horizontal support arm for supporting the corrugated expansion tube is fixed on the side of the gantry near the corrugated expansion tube.

[0013] This utility model has the following main technical advantages:

[0014] 1. A three-dimensional spraying mechanism is adopted, which simultaneously sprays lubricant onto the inner and outer rings of the wire coil through the first spray nozzle on the central tube and the second spray nozzle on the inner wall of the sliding sealing cover, ensuring comprehensive and uniform lubrication coverage and improving the quality of the coil before it leaves the factory.

[0015] 2. An integrated negative pressure demisting mechanism is used to create negative pressure during the spraying process to extract the floating atomized lubricating fluid, preventing the lubricating fluid from being randomly dispersed into the air, thus significantly reducing environmental pollution and safety hazards.

[0016] 3. The sliding sealing cover has an arched design with a strip opening at the top for easy sliding in and a flexible, drooping sealing plate at the bottom to isolate the rollers and ground rail from the internal space, preventing the atomizing liquid from escaping through gaps or adhering to and contaminating the track, thus improving overall sealing and operational hygiene.

[0017] 4. The cover is slidably installed along the ground rail axis, and works smoothly with the C-shaped hanger; the negative pressure connection port is connected to the corrugated expansion pipe through the elbow flange, and the horizontal support arm on the gantry supports the expansion pipe to prevent stretching deformation or falling damage, ensuring long-term stable operation.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0024] Reference Figure 1-3 As shown, this utility model provides a wire coil spray lubrication and negative pressure demisting device. The wire coil 5 is suspended on a C-shaped hanger 3, and the C-shaped hanger 3 is slidably installed on a gantry frame 4 (sliding direction is facing the screen).

[0025] The wire coil 5 spray lubrication and negative pressure demisting device includes a sliding sealing cover 10, a three-dimensional spray mechanism 20, and a negative pressure demisting mechanism 30.

[0026] The sliding sealing cover 10 is slidably installed on the ground rail. The sliding sealing cover 10 slides on the ground rail along the axial direction of the wire coil 5. The top of the sliding sealing cover 10 is provided with strip-shaped openings 11 distributed along the sliding direction. The sliding sealing cover 10 slides towards the C-shaped lifting device 3 so that the wire coil 5 enters the sliding sealing cover 10. The end of the sliding sealing cover 10 away from the C-shaped lifting device 3 is provided with a negative pressure connection port 12.

[0027] The three-dimensional spray mechanism 20 includes an inner ring spray mechanism 21 and an outer ring spray mechanism 22. The inner ring spray mechanism 21 and the outer ring spray mechanism 22 are connected to the lubricating fluid supply system. The inner ring spray mechanism 21 is provided with a central tube 23 axially fixed inside the sliding sealing cover 10. Multiple first spray nozzles 24 are arranged around the central tube 23. The outer ring spray mechanism 22 is provided with multiple second spray nozzles arranged circumferentially on the inner wall of the sliding sealing cover 10. The first spray nozzles 24 and the second spray nozzles are respectively facing the inner ring and the outer ring of the wire coil 5.

[0028] The sliding sealing cover 10 is connected to a negative pressure demisting mechanism 30. The negative pressure demisting mechanism 30 includes a corrugated expansion pipe 31, a steam-water separator 32, and a centrifugal fan 33. One end of the corrugated expansion pipe 31 is connected to the negative pressure connection port 12, and the other end is connected to the centrifugal fan 33 through the steam-water separator 32.

[0029] The sliding sealing cover 10 slides horizontally, allowing the wire coil 5 of the C-shaped lifting device 3 to enter the sliding sealing cover. During the sliding process, the three-dimensional spraying mechanism 20 sprays lubricant onto the inner and outer rings of the wire coil 5 simultaneously, and the negative pressure demisting mechanism 30 creates negative pressure inside the sliding sealing cover 10 to extract the atomized lubricant floating inside the sliding sealing cover 10.

[0030] In an optional embodiment, both the first and second spray nozzles are dual-flow nozzles. The dual-flow nozzle design allows the lubricant to be sprayed in a more uniform and finer mist, further ensuring that every part of the inner and outer rings of the wire coil 5 receives sufficient lubrication coverage. This reduces surface defects that may result from uneven lubrication and improves the overall quality stability of the coil. Furthermore, the dual-flow structure helps control the amount and range of lubricant sprayed, avoiding excessive spraying that could lead to lubricant waste and subsequent cleaning difficulties. It also prevents excess lubricant from escaping into the surrounding environment due to an excessively large spray range, enhancing the environmental friendliness and economy of the device.

[0031] In an optional embodiment, such as Figure 3 As shown, the sliding sealing cover 10 is arched. One end of the sliding sealing cover 10 near the C-shaped hanger 3 has an opening, while the other end is closed. Drooping sealing plates 15 and rollers 16 are provided on both the inner and outer sides of the bottom of the sliding sealing cover 10. The rollers 16 are rolled on the ground rail, and the drooping sealing plates 15, made of flexible rubber, are vertically fixed to the inner side of the sliding sealing cover 10. The drooping sealing plates 15 separate the rollers 16 and the ground rail from the internal space of the sliding sealing cover 10, improving the sealing performance of the sliding sealing cover 10 and preventing floating atomized lubricating fluid from escaping through the bottom gaps and adhering to the rollers and ground rail.

[0032] In an optional embodiment, the negative pressure connection port 12 is connected to one horizontal end of the corrugated expansion tube 31 via an elbow flange 13, allowing the corrugated expansion tube 31 to extend and retract horizontally, which is consistent with the sliding direction of the sliding sealing cover 10. Furthermore, a horizontal support arm 41 for supporting the corrugated expansion tube 31 is fixed to the side of the gantry frame 4 near the corrugated expansion tube 31, preventing the corrugated expansion tube 31 from collapsing and being damaged due to lack of support at the bottom after being stretched.

[0033] In summary, this device achieves an organic combination of lubrication protection and mist control, and is suitable for wire coil transportation scenarios. It has the advantages of simple structure, high degree of automation, and low maintenance cost, significantly improving production efficiency and environmental compliance.
