Description

Technical Field

[0001] This utility model relates to the field of enameled wire production technology, and in particular to an online surface lubricant coating device for enameled wire. Background Technology

[0002] Enamelled wire is a major type of winding wire, consisting of a conductor and an insulation layer. It has unique properties and a wide range of applications. The conductor of enamelled wire is usually made of high-purity, high-conductivity metals, such as copper or aluminum. The insulation layer is formed by coating with polymer insulating materials. Common insulating materials include acetal varnish, polyester varnish, and polyesterimide varnish. During the production of enamelled wire, a lubricant needs to be coated on the surface of the wire, thus requiring the use of an enamelled wire surface lubricant coating device.

[0003] However, existing technologies have some problems: existing coating devices are prone to dead zones in the coating of enameled wires, resulting in uneven coating and preventing the enameled wires from being fully coated in one process, which affects processing efficiency. At the same time, existing coating devices cannot collect the lubricant that is not coated on the surface of the enameled wire, resulting in waste of resources. Therefore, we propose an enameled wire surface lubricant coating device. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a device for coating the surface of enameled wire with lubricant, which adjusts the position of the spray pipe and the nozzle by a drive component, thereby making the surface of the enameled wire uniformly coated with lubricant.

[0005] This utility model is implemented as follows: a device for coating enameled wire with lubricant on the online surface includes a base, an unwinding frame fixedly connected to the base, an unwinding roller rotatably connected to the unwinding frame, a support frame fixedly connected to the base, a coating box fixedly connected to the support frame, a spraying pipe movably connected inside the coating box, a nozzle fixedly connected to the spraying pipe, a driving assembly provided on the coating box for driving the spraying pipe to move, a liquid supply assembly provided on the coating box, and a winding frame fixedly connected to the base, with a winding assembly provided on the winding frame.

[0007] Optionally, the drive assembly includes a movable plate, a guide post is fixedly connected to the coating box, the movable plate is slidably connected to the guide post, and the spray pipe is fixedly connected to the movable plate.

[0008] Optionally, the drive assembly further includes a first motor, which is fixedly connected to the coating box. The output end of the first motor is connected to a bidirectional lead screw via a coupling. The bidirectional lead screw is rotatably connected inside the coating box, and the movable plate is threadedly connected to the bidirectional lead screw.

[0009] Optionally, the liquid supply assembly includes a liquid storage tank, which is fixedly connected to a support frame, and an oil pump is fixedly connected to the coating box, the oil pump being connected to the liquid storage tank.

[0010] Optionally, the liquid supply assembly further includes a conduit, and the spraying pipe is provided in two sets, which are connected by the conduit, one of which is connected to the oil pump.

[0011] Optionally, the winding assembly includes a winding roller rotatably connected to a winding frame, a second motor fixedly connected to the base, a first gear keyed to the output end of the second motor, and a second gear fixedly connected to one end of the winding roller, wherein the first gear meshes with the second gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a drive assembly. The distance between the two sets of spray pipes is adjusted by the drive assembly so that the nozzle can adapt to enameled wires of different diameters and ensure that the surface of the enameled wire can be fully coated with lubricant. By starting the first motor, the bidirectional lead screw is driven to rotate. After the bidirectional lead screw rotates, it will drive the movable plate to slide on the guide post, thereby adjusting the distance between the two sets of movable plates, that is, adjusting the position of the spray pipe and the nozzle.

[0014] 2. Before the enameled wire is coated with lubricant, it is cleaned with a cleaning sponge to reduce dust and prevent lubricant from falling off. After cleaning, the enameled wire is moved between two sets of spray tubes for lubricant spraying. After spraying, the enameled wire is moved to the cleaning ring, where a brush applies lubricant to the surface of the wire, ensuring even application and removing excess lubricant. The collection tank at the bottom of the coating box collects the lubricant brushed off and any remaining lubricant for reuse. Attached Figure Description
