Description

Technical Field

[0001] This utility model belongs to the field of electric heating wire processing technology, and relates to an electric heating wire surface polishing device. Background Technology

[0002] As a key component for converting electrical energy into heat energy, heating wires are widely used in various fields such as household appliances (e.g., hair dryers, rice cookers, heaters), industrial furnaces, experimental equipment, and aerospace. During the production process, a layer of oxide scale, oil stains, scratches, and micro-burrs inevitably forms on their surface, directly affecting the efficiency, lifespan, and safety of heating devices. Due to the small diameter of the heating wire, traditional mechanical polishing pressure and abrasive wear are difficult to control precisely, easily leading to uneven polishing and even new scratches. Therefore, it is essential to design a surface polishing device for heating wires to better polish their surfaces. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device for polishing the surface of an electric heating wire.

[0004] The objective of this utility model can be achieved through the following technical solution: A surface polishing device for an electric heating wire, comprising a housing, characterized in that a feed inlet is provided at the top of the housing, and a polishing mechanism is installed at the feed inlet. The polishing mechanism includes a cylindrical body, which is vertically rotatably mounted at the feed inlet at the top of the housing. A toothed groove is provided on the outer ring of the cylindrical body, and a drive mechanism for controlling the rotation of the cylindrical body is connected through the toothed groove. The drive mechanism includes a mounting base, on which a drive motor is vertically mounted upwards. A drive gear is mounted on the output shaft of the drive motor. The cylinder is meshed with the toothed groove. A polishing cylinder is installed inside the cylinder. A grinding part is provided on the inner wall of the polishing cylinder. The upper end of the cylinder is the feed port and the lower end is the discharge port. The discharge port is connected to the inside of the box. A guide wheel is installed below the discharge port inside the box. Channel 1 and Channel 2 are provided on both sides of the guide wheel. A cleaning mechanism is installed at the top of the box. The cleaning mechanism includes a bellows. An air outlet 1 is provided in front of the bellows and the air outlet 2 is provided on both sides of the bellows through the extension pipe. The air outlet 2 is directly opposite to both sides of the heating wire conveying direction.

[0005] The working principle of this utility model is as follows: The heating wire is introduced into the cylinder through the feed port. During this process, the drive motor controls the drive gear to rotate, which in turn drives the cylinder to rotate. The surface of the heating wire entering the cylinder is polished by the polishing part on the inner wall of the polishing cylinder. After that, the heating wire enters the box through the discharge port and is guided to channel two by the guide wheel. During this process, the air box controls the air outlet one and air outlet two to clean the grinding debris and dust on the surface of the heating wire. The grinding debris and dust are then collected and discharged through channel one.

[0006] A rotating component is installed at the connection between the cylinder and the box.

[0007] With the above structure, the cylinder is rotated by a rotating component.

[0008] The polishing cylinder is provided with a protrusion corresponding to the cylinder body.

[0009] The above structure facilitates the positioning and fixation of the polishing cylinder after it is inserted into the cylinder body.

[0010] The inlet of the polishing cylinder is chamfered.

[0011] The above structure is used to assist in the introduction of the heating wire.
