Abstract
Description
Technical Field
[0001] This utility model relates to a lubrication coating device, and more particularly to a lubricant coating device for enameled wire surfaces. Background Technology
[0002] Enamelled wire, also known as magnet wire, is a core basic material in the electrical engineering field. Essentially, it is a conductor formed by coating multiple layers of special insulating varnish onto the surface of a metal conductor. Lubrication of enamelled wire (magnet wire) is a crucial step in cable manufacturing and application, directly affecting winding efficiency, varnish life, and the performance of motors / transformers. Lubrication typically involves using sponges or felt arranged vertically to absorb lubricant and clamp the wire. During lubrication, the sponge is under constant pressure, which can cause deformation, reducing the effectiveness of lubricant extrusion and affecting the processing quality of the enamelled wire. Utility Model Content
[0003] The purpose of this invention is to provide a lubrication coating device for enameled wire. It facilitates adjustment of the spacing between the lubrication wheels, thereby altering the squeezing effect between the sponges, thus enabling effective application of lubricant to the enameled wire and improving the processing quality of the enameled wire.
[0004] The technical solution of this utility model is as follows: A lubrication coating device for enameled wire surface includes a machine body. The machine body is provided with a first lubrication wheel group and a second lubrication wheel group arranged front and rear. The first lubrication wheel group and the second lubrication wheel group are respectively provided with a first lubrication pool and a second lubrication pool on their lower sides. A cleaning roller is provided on the front side of the first lubrication wheel group, and a squeezing roller is provided on the rear side of the second lubrication wheel group. Both the first lubrication wheel group and the second lubrication wheel group include two sets of mounting shafts. A lubrication wheel is provided on the mounting shaft. A sponge sleeve is provided on the outer ring of the lubrication wheel. Mounting blocks are provided at both ends of the mounting shaft and are installed in the machine body and can move up and down. A drive mechanism for adjusting the position of the mounting block is provided on both sides of the mounting block.
[0005] In the aforementioned enameled wire surface lubrication coating device, the driving mechanism includes a bidirectional lead screw located on one side of the machine body, and the bidirectional lead screw is provided with a lead screw seat corresponding to the mounting block.
[0006] In the aforementioned enameled wire surface lubrication coating device, the frame is provided with a limiting guide groove corresponding to the mounting block.
[0007] In the aforementioned enameled wire surface lubrication coating device, the side walls of the first lubrication pool and the second lubrication pool are provided with drain ports, and screen covers are provided at the drain ports. The bottom of the first lubrication pool and the second lubrication pool are provided with slopes that are lower near the drain ports and higher away from the drain ports. A waste discharge port is provided at the bottom of one side of the slope.
[0008] Compared with the prior art, the present invention has the following advantages:
[0009] This application allows for alternating lubrication of the enameled wire by setting up a first lubrication wheel set and a second lubrication wheel set, reducing downtime for maintenance. Furthermore, to prevent the sponge from deforming during prolonged compression lubrication and thus reducing the amount of lubricating oil squeezed out, this application uses a bidirectional screw to adjust the distance between the lubrication wheels, thereby changing the sponge compression effect and ensuring that the enameled wire is effectively lubricated.

Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0014] Example. A lubrication coating device for enameled wire surface, configured as follows: Figure 1-2 As shown, the machine includes a body 1. Inside the body 1, there are a first lubrication wheel group 2 and a second lubrication wheel group 3 arranged front and rear. The first lubrication wheel group 2 and the second lubrication wheel group 3 are respectively provided with a first lubrication pool 4 and a second lubrication pool 5 on their lower sides. A cleaning roller 6 is provided on the front side of the first lubrication wheel group 2, and a squeezing roller 7 is provided on the rear side of the second lubrication wheel group 3. The first lubrication wheel group 2 and the second lubrication wheel group 3 each include two sets of mounting shafts 10. A lubrication wheel 11 is provided on the mounting shaft 10. A sponge sleeve 12 is provided on the outer ring of the lubrication wheel 11. Mounting blocks 8 are installed in the body 1 and can move up and down at both ends of the mounting shaft 10. A drive mechanism for adjusting the position of the mounting block 8 is provided on both sides of the mounting block 8.
[0015] The drive mechanism includes a bidirectional lead screw 14 located on one side of the machine body 1, and a lead screw seat 15 corresponding to the mounting block 8 is provided on the bidirectional lead screw 14.
[0016] The frame 1 is provided with a limiting guide groove 13 corresponding to the mounting block 8.
[0017] The first lubrication pool 4 and the second lubrication pool 5 are provided with drain outlets 9 on their side walls. A screen cover 16 is provided at the drain outlets 9. The bottom of the first lubrication pool 4 and the second lubrication pool 5 is provided with a slope 17 that is lower near the drain outlets 9 and higher away from the drain outlets 9. A waste outlet 18 is provided at the bottom of one side of the slope 17.
[0018] The principle of this utility model is as follows: In use, the wire first passes through a cleaning roller 6, which can be a cleaning roller with a brush on its surface. A blower nozzle is located on the rear side of the cleaning roller 6 to remove impurities from the surface of the enameled wire. The wire then enters either the first lubrication wheel set 2 or the second lubrication wheel set 3. Only one set lubricates the wire at a time; the reason for having two sets is to reduce downtime. Normally, impurities on the surface of the enameled wire contaminate the sponge and lubricant, requiring periodic shutdowns for replacement. Although this application uses a cleaning roller 6 to clean the enameled wire, actual production cannot achieve 100% removal of impurities, thus requiring shutdowns for replacement. During shutdowns for replacement, the sponge sleeve 12 on the surface of the lubrication wheel 11 needs to be replaced, which takes some time. This application uses two sets of lubrication wheels, a first lubrication wheel set 2 and a second lubrication wheel set 3, and controls the separation or contact between the lubrication wheel 11 and the sponge sleeve 12 and the enameled wire via a motor-driven bidirectional lead screw 14. This allows for the replacement of the sponge sleeve 12. Furthermore, when the sponge sleeve 12 is not in contact with the enameled wire, the lubricant in the first lubrication pool 4 or the second lubrication pool 5 can be replaced. A drain port 9 is provided on one side of the first lubrication pool 4 or the second lubrication pool 5 for discharging the lubricant. A screen cover 16 is provided outside the drain port 9 to block impurities, allowing the discharged lubricant to be reused. During the continuous discharge of lubricant, impurities accumulate at the bottom of the first lubrication pool 4 or the second lubrication pool 5 and can then be discharged through the waste discharge port 18, which is equipped with a gate. When the sponge sleeve 12 deforms, the bidirectional lead screw can drive the mounting shaft 10 to move in opposite directions, thereby improving the lubricant extrusion effect and enhancing the lubrication effect. After being coated with lubricant, the enameled wire passes through the extrusion roller 7 to remove excess lubricant from its surface.
