Description

Technical Field

[0001] This utility model relates to the technical field of enameled wire processing equipment, and in particular to a wire feeding roller frame and a cooling mechanism having the roller frame. Background Technology

[0002] Annealing is required during the production and processing of enameled wire. During annealing, impurities such as lubricant, oxide scale, or high-temperature carbides may remain on the copper wire surface, affecting the adhesion of subsequent coatings. Therefore, cooling and cleaning are necessary after annealing. After cleaning, the enameled wire needs further cooling via an air-cooling system to remove water stains. CN220771761U discloses a high-speed air-blowing structure, including: a square tube, which is hollow inside and has sealed openings at both ends. The square tube is fixedly installed at the rear of the flushing section; a partition plate divides the inside of the square tube into multiple chambers; wires pass through the square tube; connecting pipes are installed on the square tube, with one connecting pipe at each chamber so that one end of the connecting pipe is connected to the chamber; blowers are matched in number with the connecting pipes, and the other end of the connecting pipes is installed at the air outlet of the blowers; it also includes air nozzles on the square tube, the number of air nozzles is matched in number with the wires, the inner diameter of the air nozzles is connected to the chambers, and a wire is provided in the inner diameter of each air nozzle.

[0003] In the existing technology, the enameled wire is conveyed by a conveyor roller. During the conveying process, an external blower blows cold air onto the conveyed enameled wire. When the enameled wire is being dried and cooled, in order to reserve a sufficient cooling section on the enameled wire, the impact of the air force can easily cause the enameled wire to sway. This not only affects the conveying stability of the enameled wire, but also makes it easy for the enameled wire to come into contact with other external structures and reabsorb moisture.

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] In the existing technology, the enameled wire is conveyed by the conveying roller 210. During the conveying process, an external blower blows cold air onto the conveyed enameled wire. When the enameled wire is being air-dried and cooled, in order to reserve a sufficient cooling section on the enameled wire, the feed roller and the discharge roller are usually set to be far apart. When blowing air, the impact of the air force can easily cause the enameled wire to shake, which will affect the conveying stability of the enameled wire. At the same time, the shaking of the enameled wire can easily come into contact with the inner wall of the external square tube, absorbing the moisture condensed on the inner wall, which will affect the effect of removing water stains from the enameled wire.

[0028] This utility model provides a wire feeding roller frame, such as Figure 1 and Figure 2 As shown, in this embodiment, the wire feeding roller is mounted inside the air-cooling box 500. The wire feeding roller frame includes a first frame 100 and a second frame 200. The first frame 100 is located on the side of the second frame 200. A guide roller 110 is mounted on the first frame 100, and a conveying roller 210 is mounted on the second frame 200. The enameled wire is conveyed by the cooperation of multiple conveying rollers 210. When discharging, the enameled wire is guided and sent out by the guide roller 110. A wire groove is provided on the conveying roller 210 to ensure the stability of the conveying of the enameled wire.

[0029] An air supply box 300 is provided on one side of the second frame 200. A connector is provided on the air supply box 300, which connects to a blower, thereby enabling air supply to the air supply box 300 via the blower. Multiple evenly spaced conveyor rollers 210 are provided on the second frame 200. These rollers can be positioned at the same height or at different heights, allowing the enameled wire to be conveyed in a serpentine pattern through the rollers. Figure 3As shown, an air supply chamber is provided inside the conveying roller 210, and air supply holes 211 are evenly arranged around the periphery of the conveying roller 210. The air supply holes 211 are connected to the air supply chamber so that gas can be discharged from the air supply holes 211 and blown onto the enameled wire being conveyed. An air valve assembly 400 is provided between the air supply box 300 and the second frame 200. The air valve assembly 400 opens and closes the air inlet and controls and adjusts the flow rate and velocity of the gas entering the air supply chamber. There are multiple air valve assemblies 400, and their number is the same as the number of conveying rollers 210. Each air valve assembly 400 is connected to the air supply chamber in one conveying roller 210, and each air valve assembly 400 independently controls and adjusts the air intake in one conveying roller 210.

[0030] The wire feeding roller frame of this utility model can simultaneously install guide rollers 110 and multiple conveying rollers 210. The enameled wire on the conveying rollers 210 is cooled and dried by blowing air on them. Compared with the prior art, there is no need to reserve a cooling section. Multiple conveying rollers 210 can cooperate to transport the wire while it is being cooled. The air blowing operation of the conveying rollers 210 makes the transport of the enameled wire less likely to be deviated by the wind force, ensuring the stability of the transport. The wire will not shake due to the air blowing while it is being cooled.

[0031] In order to facilitate the drainage of water stains cleaned from the bottom of the conveyor roller 210 and avoid water accumulation, an inclined drainage plate 220 is provided at the bottom of the second frame 200. The drainage plate 220 is inclined downward on the side near the inlet 510 of the air-cooled box 500 to drain the water on the wire feed roller frame in time.

[0032] To adjust the angle of the lead-out line and improve overall flexibility, such as Figure 4 As shown, an adjusting cylinder 230 is installed on the side of the second frame 200 facing the first frame 100. The output end of the adjusting cylinder 230 is connected to the first frame 100. The adjusting cylinder 230 drives the first frame 100 to move closer to or away from the second frame 200. A limiting slide 120 is provided on the first frame 100. The limiting slide 120 is slidably connected to the bottom of the second frame 200 to limit the movement of the first frame 100 and ensure the stability during adjustment and movement.

[0033] like Figure 5 As shown, a first guide roller and a second guide roller are provided on the first frame 100, with the first guide roller located at the bottom of the second guide roller; a lifting cylinder 130 is provided on the first frame 100, and the lifting cylinder 130 is connected to the second guide roller to drive the second guide roller to lift.

[0034] This utility model also discloses a cooling mechanism, such as Figure 6As shown, the device includes an air-cooled box 500 and the wire feeding roller frame in the above embodiment, with the wire feeding roller frame installed inside the air-cooled box 500. A second frame 200 is fixed inside the air-cooled box 500, and a first frame 100 is slidably disposed inside the air-cooled box 500. The air-cooled box 500 has a wire inlet 510 and a wire outlet 520, with the first frame 100 located on the side near the wire outlet 520. The wire inlet 510 is located on the side of the air-cooled box 500, and the wire outlet 520 is located on the top of the air-cooled box 500. The side of the air-cooled box 500 is configured with a mesh structure to prevent external impurities from entering and to allow water vapor to escape.

[0035] To avoid cluttered external piping, an air supply pipe 530 is installed on the outside of the air-cooled box 500 and fixed to the air-cooled box 500. One end of the air supply pipe 530 extends downward to connect with the blower, and the other end enters the interior of the air-cooled box 500 and connects with the wire feeding roller frame. Air is supplied to the air supply box 300 through the air supply pipe 530.

[0036] In order to expel the moisture in the air-cooled box 500, a pusher fan 540 is installed inside the air-cooled box 500 on one side of the outlet 520. The pusher fan 540 blows air from the outlet 520 to the inlet 510, that is, blows air in the opposite direction of the enameled wire transport, and discharges the gas mixed with moisture inside the air-cooled box 500 from the outlet 520. This reduces the moisture in the air-cooled box 500, improves the effect of removing water stains, and prevents the moisture mixed in the gas from being re-absorbed onto the enameled wire. Moreover, the horizontal blowing method can further improve the effect of removing water stains from the enameled wire and quickly drive the water accumulated on the drain plate 220 out.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
