Description

Technical Field

[0001] This utility model belongs to the field of bare stranded wire coating, and specifically relates to a bare stranded wire anti-corrosion coating device. Background Technology

[0002] There are two forms of anti-corrosion oil coating for bare stranded wires: hot coating and cold coating. Hot coating refers to heating the anti-corrosion grease in a heating box until it becomes liquid, and then immersing the bare stranded wire in the liquid grease. After the grease comes into contact with the cold bare stranded wire, it solidifies and adheres to the wire. However, some components of the grease will decompose during the heating process, which cannot guarantee the final coating performance of the bare stranded wire.

[0003] Therefore, the commonly used technology currently employs cold coating. Cold coating involves passing the bare stranded wire through solidified grease, causing the outer side of the wire to pick up and carry away the grease. The excess grease on the outer side of the wire is then scraped off. The grease used in cold coating is a non-dripping, butter-like material. After the bare stranded wire passes through the grease, without external force, voids will form within the grease where the wire passed. This means that subsequent stranded wires passing through the same area will not be properly coated. The current practice is to continuously stir the grease to avoid voids. However, using simple mechanical stirring equipment with a fixed stirring trajectory cannot completely prevent void formation. Manual stirring requires a huge amount of labor, and neither method effectively solves the aforementioned problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a bare stranded wire anti-corrosion coating device to solve the problem that grease will form voids where bare stranded wires pass through, so that the coating amount cannot be guaranteed when subsequent bare stranded wires pass through the same spot.

[0005] According to the embodiments of this utility model, the following technical solution is adopted: A bare stranded wire anti-corrosion coating device includes an oiling mechanism and an oil scraping mechanism. The oiling mechanism includes an oiling tank with at least one partition plate installed in the middle, dividing the oiling tank into multiple parallel chambers. Wire passage holes are provided on both side walls of the oiling tank and on the partition plate, and multiple wire passage holes are coaxially arranged to form a wire passage channel. Pressure plates are slidably connected vertically in each chamber, and counterweights are provided on the pressure plates. The oil scraping mechanism includes an oil scraping box and an oil scraping plate detachably connected in the oil scraping box. Through holes are provided on both side walls of the oil scraping box, and oil scraping holes are provided on the oil scraping plate for the coated bare stranded wire to pass through. The projection of the oil scraping hole along its axial direction is completely located within the through hole. An oil collection space is provided between the two sides of the oil scraping hole along its axial direction and the inner wall of the oil scraping box. The oil scraping hole is located at the end of the wire passage channel and is coaxial with the wire passage channel.

[0006] Compared with the prior art, the present invention has the following beneficial effects: 1. In this solution, through the design of multiple chambers, the bare stranded wire passes through multiple chambers in sequence for coating. Due to factors such as the fluidity of the grease or the speed of the bare stranded wire passing through the chambers, there may be local voids or uneven coating in the early chambers. However, after passing through multiple chambers, multiple coatings will be completed, filling the voids or thin areas that may have remained in the early stages, thereby forming a more uniform and complete grease coating.

[0007] Each chamber is equipped with a pressure plate, which, under the influence of the counterweight, presses the grease downwards. This allows for the rapid replenishment of any voids that appear in the grease, and continuous pressure reduces the probability of voids. While the pressure plates in the multiple chambers operate independently, they work together to ensure that the grease remains in constant contact with the surface of the bare stranded wire, further reducing the likelihood of voids forming.

[0008] In addition, a single chamber may require frequent adjustments or replenishment of grease due to grease consumption or cavity accumulation. However, when multiple chambers are used in series, even if one chamber is being replenished with grease, other chambers can continue to operate, avoiding interruptions due to insufficient grease and improving production efficiency.

[0009] 2. Remove excess grease from the outside of the bare stranded wire through the grease scraper hole. The design of the grease collection space reduces grease adhesion to the inner wall of the grease scraper box. Even if the grease flows downward, it will remain in the grease scraper box for easy subsequent processing.

[0010] Furthermore, guide ramps are provided on both sides of the bottom of the oiling tank, which are used to guide the grease to the bottom of the oiling tank.

[0011] Furthermore, a groove is provided on the inner wall of the oiling tank, with the upper end of the groove open. A slider is provided on the pressure plate, and the slider is slidably connected in the groove.

[0012] Furthermore, each pressure plate has a pressure rod fixed to its upper end, and the upper end of the partition plate extends out of the oiling tank and is equipped with a guide plate. The guide plate has a guide hole for the pressure rod to pass through.

[0013] Furthermore, the counterweights on the pressure plates in multiple chambers increase in weight sequentially along the axial direction of the wire passage.

[0014] Furthermore, the inner wall of the scraper box is provided with a slot for inserting the scraper blade.

[0015] Furthermore, the oil scraper hole is frustum-shaped, and the large-diameter end of the oil scraper hole is the inlet end for the bare stranded wire to enter.

[0016] Furthermore, the oil scraper comprises two parallel plates, each with a U-shaped groove. The openings of the U-shaped grooves on the two plates face opposite directions, and the two U-shaped grooves cooperate to form an oil scraping hole.

[0017] Furthermore, the inner wall of the U-shaped groove is provided with an elastic pad.

[0018] Furthermore, a limiting plate is installed on the top of the oil scraper box to limit the vertical movement of the plate. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given. like Figure 1 As shown, the bare stranded wire 3 anti-corrosion coating device includes an oiling mechanism and an oil scraping mechanism. The oiling mechanism includes an oiling tank 2, and at least one partition 5 is installed in the middle of the oiling tank 2. The partition 5 divides the oiling tank 2 into multiple parallel chambers 1, which are used to prevent the application of anti-corrosion grease. Wire-passing holes 4 are provided on both side walls of the oiling tank 2 and on the partition 5, and the multiple wire-passing holes 4 are coaxially arranged to form a wire-passing channel through which the bare stranded wire 3 passes. Figure 2 As shown, in order to guide the grease to gather and flow to the bare stranded wire 3, guide ramps 10 are provided on both sides of the bottom of the oiling tank 2. The guide ramps 10 are used to guide the grease to the bottom of the oiling tank 2.

[0025] Each chamber 1 is vertically connected with a pressure plate 9. In order to make the pressure plate 9 move vertically, a groove is provided on the inner wall of the oiling tank 2. A slider is provided on the pressure plate 9. The slider is slidably connected in the groove. The groove is used to limit the sliding path of the pressure plate 9. The upper end of the groove is open, so that the pressure plate 9 can slide upward out of the oiling tank 2, thereby allowing grease to be added in the oiling tank 2.

[0026] Each pressure plate 9 has a pressure rod 7 fixed to its upper end. The pressure rod 7 allows for manual control of the sliding of the pressure plate 9 when necessary. The upper end of the partition plate 5 extends out of the oiling tank 2 and is equipped with a guide plate 6. The guide plate 6 has a guide hole for the pressure rod 7 to pass through. The guide hole limits the pressure rod 7, further ensuring that all pressure plates 9 move vertically.

[0027] The pressure plate 9 is equipped with a counterweight 8. The counterweight 8 is designed to exert downward pressure on the pressure plate 9, and the pressure plate 9 can press the grease downward, so that when cavities appear in the grease, they can be quickly replenished by downward pressure. Continuous pressing of the grease reduces the probability of cavities.

[0028] The oil scraping mechanism is located after the oiling mechanism. The bare stranded wire 3 enters the oil scraping mechanism after being discharged from the wire passage. The oil scraping mechanism is used to scrape away excess and uneven grease from the bare stranded wire 3, forming a uniform oil film. In actual design, the oil scraping mechanism and the oiling box 2 can be placed together without connection, or they can be assembled and fixed together. Specifically, the oil scraping mechanism includes an oil scraping box 15 and an oil scraper 12 detachably connected inside the oil scraping box 15. To facilitate easy replacement of the oil scraper 12, the inner wall of the oil scraping box 15 has a slot for inserting the oil scraper 12. The end of the slot is open, allowing the oil scraper 12 to be completely pulled out of the slot. The slot limits the oil scraper 12, facilitating maintenance, cleaning, or replacement of oil scrapers 12 of different specifications.

[0029] Both sides of the oil scraper box 15 have through holes 11, and the oil scraper plate 12 has oil scraping holes 14 for the coated bare stranded wire 3 to pass through. The projection of the oil scraping hole 14 along its axial direction is completely located within the through hole 11 to avoid the through hole 11 from affecting the passage of the bare stranded wire 3. In this embodiment, the through hole 11 is U-shaped. During assembly, the oil scraping hole 14 is located at the tail end of the wire passage and is coaxial with the wire passage.

[0030] The oil scraper 12 has an oil collection space 13 between the two sides of the oil scraper hole 14 along the axial direction and the inner wall of the oil scraper box 15. After the bare stranded wire 3 passes through the oil scraper hole 14, some grease will remain on the inner wall of the oil scraper hole 14 or the side of the oil scraper 12. The design of the oil collection space 13 reduces the adhesion of grease to the inner wall of the oil scraper box 15. Even if the grease flows downward, it will remain in the oil scraper box 15 for easy subsequent processing.

[0031] Based on this embodiment, two design methods for the oil scraper hole 14 are given below: A. The scraper hole 14 is truncated cone-shaped, and the large-diameter end of the scraper hole 14 is the inlet end for the bare stranded wire 3 to enter. The truncated cone-shaped design makes it easy for the bare stranded wire 3 coated with grease to enter the scraper hole 14.

[0032] B. Combination Figure 3 , Figure 4As shown, the scraper 12 comprises two parallel plates 16, each with a U-shaped groove 17. The openings of the U-shaped grooves 17 on the two plates 16 face opposite directions, and the two U-shaped grooves 17 cooperate to form a scraping hole 14. The split design makes the installation, disassembly, and cleaning of the scraper 12 more convenient. When the worker inserts the bare twisted wire 3 into the scraping hole 14, there is no need to thread the wire from the end of the bare twisted wire 3. Simply close the two plates 16 together on the bare twisted wire 3 from the left and right or top and bottom, and then insert them into the scraper box 15. During maintenance, simply separating the two plates 16 is sufficient to thoroughly clean the residue in the U-shaped grooves 17.

[0033] The inner wall of the U-shaped groove 17 is provided with an elastic pad, which can be made of rubber material. The design of the elastic pad allows it to better fit the surface of the bare stranded wire 3. Even if the bare stranded wire 3 has slight diameter unevenness or wobbling, it can effectively scrape off the oil and reduce the wear on the surface of the bare stranded wire 3.

[0034] To ensure that the plate 16 will not be misaligned or float due to grease pressure during operation, a limiting plate 18 is installed on the top of the oil scraper box 15 to limit the vertical movement of the plate 16. The limiting plate 18 constrains the vertical movement of the plate 16 to ensure its stability after assembly, thereby ensuring that the shape and size of the oil scraper hole 14 remain unchanged. Specifically, the limiting plate 18 is bolted to the top of the oil scraper box 15.

[0035] In practical use, the bare stranded wire 3 passes through multiple chambers 1 sequentially via the wire passage for coating. Due to factors such as grease flowability or the speed at which the bare stranded wire 3 passes through chambers 1, local voids or uneven coating may appear in the early stages of chamber 1. However, after passing through multiple chambers 1, multiple coating processes are completed, filling any voids or thin areas that may have remained in the early stages, thus forming a more uniform and complete grease coating. During this process, the pressure plate 9 is constantly pressed downwards by the gravity of the counterweight 8, pressing down on the grease.

[0036] After exiting the wire passage, the bare stranded wire 3 enters the oil scraper box 15 and then the oil scraper hole 14. Based on the size setting of the oil scraper hole 14, the excess grease on the bare stranded wire 3 is scraped off, so that the grease on the outer layer of the bare stranded wire 3 forms a circle of regular size.

[0037] In another embodiment of this invention, to achieve a gradual coating effect on the bare stranded wire 3 from shallow to deep, the counterweights 8 on the pressure plates 9 in multiple chambers 1 increase in weight sequentially along the wire passage axis. When the bare stranded wire 3 enters the first chamber 1, the grease in the first chamber 1 experiences the lightest pressure from the pressure plate 9. At this time, the pressure plate 9 gently coats the surface of the bare stranded wire 3 with the grease. Due to the low pressure, the problem of the grease being violently squeezed apart due to excessive resistance, resulting in poor coating effect, can be avoided. Then, the bare stranded wire 3 enters the second chamber 1, where the weight of the pressure plate 9 increases, resulting in greater pressure on the grease. The greater pressure drives the grease to penetrate deeper into the surface of the bare stranded wire 3, squeezing out any tiny air bubbles that may exist in the previous coating, ensuring the density of the coating. If there are a third or fourth chamber 1 subsequently, the coating effect can be further improved. Through the gradual pressurization method in this embodiment, compared with the design of equal pressure in all chambers 1, the permeability and adhesion of the grease can be significantly improved, effectively preventing the formation of voids and obtaining a coating with a more uniform thickness.
