Description

Technical Field

[0001] The utility model relates to the technical field of heating wire production, in particular to a winding device for a double-layer insulation heating wire. Background Art

[0002] The heating wire is a wire that generates heat by utilizing the thermal effect of electric current after being energized. There are many types of heating wires, which are called resistance wires or resistance wires in basic physics. According to the conductor, they are mainly divided into nickel-chromium alloy wire, constantan wire, carbon fiber, etc. According to the insulator, they are divided into silicone, PVC, Teflon, glass fiber, etc. The heating wire needs to be stored after production, usually wound on the outside of the winding roller for storage. During the winding process, local winding will occur, resulting in uneven winding density of the winding roller and poor winding effect. Utility Model Content

[0003] In order to solve the technical problems existing in the background technology, the utility model provides a winding device for a double-layer insulation heating wire.

[0004] The utility model proposes a winding device for a double-layer insulated heating wire, which comprises a winding roller, a guide rail and a reciprocating screw rod. The axes of the guide rail and the reciprocating screw rod are parallel to the axis of the winding roller. A slider is slidably connected to the guide rail. A moving part is connected to the slider through a connecting part. The moving part is threadedly connected to the reciprocating screw rod. A sleeve is connected to the outer wall of the moving part through a bearing sleeve, and the sleeve can rotate on the outer wall of the moving part.

[0005] Preferably, the length of the reciprocating screw rod is equal to the length of the winding roller.

[0006] Preferably, the outer rings at both ends of the sleeve are provided with side plates.

[0007] Preferably, the outer circles of the opposite surfaces of the two groups of side plates are both provided with arc-shaped protrusions.

[0008] Preferably, the moving member is cylindrical, the axis of the moving member coincides with the axis of the reciprocating screw, and the sleeve is slidably sleeved on the outer wall of the moving member.

[0009] Preferably, the connecting members are provided in two groups, which are respectively located at two ends of the moving member.

[0010] Preferably, outer walls at both ends of the winding roller are fixedly connected to limit plates.

[0011] In the utility model, a winding device for a double-layer insulated heating wire is proposed. Before the double-layer insulated heating wire is wound onto a winding roller, it first passes through a sleeve on a reciprocating screw rod. The guide rail limits the direction of the slider, and the motor drives the reciprocating screw rod to rotate, thereby driving the moving part to perform reciprocating motion on the reciprocating screw rod under the limit of the slider. The sleeve can rotate on the outer wall of the moving part. Before the double-layer insulated heating wire is wound on the winding roller, it first passes through the sleeve to guide it, so as to avoid local concentrated winding on the winding roller, resulting in uneven winding and poor winding effect. The rotation speed of the reciprocating screw rod can control the moving speed of the moving part, so as to ensure that the heating wire can be evenly wound on the winding roller.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
