Description

Technical Field

[0001] The utility model relates to the technical field of electric heating wire production, in particular to a fixing device for electric heating wire production. Background Art

[0002] The heating wire is a special resistor material with suitable resistivity, high melting point and good chemical stability. When current passes through the heating wire, due to the existence of resistance, the electrical energy is converted into thermal energy, thus making the heating wire heat up. By adjusting the size and time of the current, the heat generated by the heating wire can be precisely controlled, thereby achieving temperature control of the heating equipment.

[0003] The heating wire needs to be laid in the heating equipment to increase the heating area of ​​the equipment. Usually, the heating wire is laid on the corresponding equipment during the production process of the heating wire. For example, a heating wire laying device for special electric heating glass production with publication number CN217127291U includes a support frame, and the front and rear side walls and the left side wall of the base are all provided with support frames; the top of the support frame of the front and rear side walls and the left side wall of the shell base are all provided with a shell. The staff grasps the handle to drive the shell to move downward, and the baffle is rotated downward with the shaft as the center under the action of force.

[0004] This device places the designated heating wire in the slot for positioning. During the laying process of the heating wire, the heating wire is not pressed, so the heating wire may move in the vertical plane. The lack of pressure during the laying process of the heating wire causes the wire to loosen, resulting in uneven laying. Summary of the invention

[0005] The utility model aims to solve the problem that the heating wire of the background art may become loose in the vertical direction during the laying process due to lack of pressing and fixing, resulting in uneven laying, and proposes a fixing device for the production of heating wire.

[0010] As a further solution of the utility model: the shape of the fixing sleeve is adapted to the shape of the correspondingly arranged groove.

[0011] As a further solution of the utility model: the limiting columns on both sides are symmetrically arranged with respect to the central plane of the bottom plate, and the limiting columns on both sides are arranged along the vertical direction.

[0012] As a further solution of the utility model: the top ends of the limiting column and the sliding column extend above the cover plate and are respectively provided with a first sealing disk and a second sealing disk; the upward projections of the cross sections of the limiting column and the sliding column are respectively located inside the first sealing disk and the second sealing disk.
