Description

Technical Field

[0001] This utility model belongs to the field of electric heating wire production technology, and relates to a cooling device for an electric heating wire extrusion machine. Background Technology

[0002] A heating wire is a resistance wire that converts electrical energy into heat energy, typically made of a metal or alloy material with high resistivity. When an electric current passes through it, the heating wire heats up and is widely used in heating equipment. Heating wires used in household appliances (electric blankets, heating elements, etc.) usually require an insulation layer, which necessitates processing them using an extrusion machine. After extrusion, the heating wire material (such as a plastic or rubber coating) is in a high-temperature molten state. Cooling allows it to solidify quickly, maintaining the required shape and dimensional accuracy and preventing deformation or shrinkage. Traditional heating wire extrusion machines typically use a single water-cooling or air-cooling method, which generally has limited cooling efficiency. Therefore, designing a cooling device for heating wire extrusion machines is essential to improve cooling effect and efficiency. Summary of the Invention

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

The cooling box 2 is equipped with guide rollers 3 and 4. An atomizing device is installed at the bottom of the cooling box 2. A return air pipe 2 that cooperates with the atomizing device is installed at the top of the cooling box 2. The outlet of the cooling box 2 is connected to the cooling box 3 through a cable bundle 3.

[0005] The working principle of this utility model is as follows: The heating wire, after being extruded by the extruder, enters the cooling box 1 through the first wire bundle tube. The heating wire is initially air-cooled by the blowing fan and the return air pipe. The heating wire in the cooling box 1 passes through the first and second guide rollers and then enters the cooling box 2 through the second wire bundle tube. Water mist is sprayed out by the atomizing device and the heating wire is cooled again by the return air pipe 2. The heating wire in the cooling box 2 passes through the third and fourth guide rollers and then enters the cooling box 3 through the third wire bundle tube. The heating wire is water-cooled again by the water spraying device. Then, the heating wire is guided into the water cooling chamber by the fifth guide roller for final water cooling and is discharged from the water cooling chamber through the fourth wire bundle tube. After being stretched and extended by the stretching mechanism, it is discharged.

[0006] The stretching mechanism includes a stretching wheel one, a stretching wheel two, and a positioning wheel group one. The stretching wheel one is installed at the outlet of the cable bundle four, and the stretching wheel two and the positioning wheel group one are installed above the stretching wheel one in sequence.

[0007] Using the above structure, the heating wire is stretched and extended by stretching wheel one and stretching wheel two in sequence, and then positioned and led out by positioning wheel group one.

[0008] Inside the second cooling box, an air intake fan is installed at the inlet of the second return air duct.

[0009] Using the above structure, water mist is drawn in and discharged by an air intake fan.

[0010] The water-cooled chamber is connected to a water spray device via a connecting pipe. A water pump is installed at the inlet of the connecting pipe inside the water-cooled chamber.

[0011] Using the above structure, water is supplied to a pair of spray devices through a water pump and connecting pipe.

[0012] The water-cooled chamber is connected to the atomizing device via a connecting pipe.

[0013] Using the above structure, water is supplied to the atomizing device through the second connecting pipe.

[0014] Inside the water-cooled chamber, a positioning wheel set two is installed at the inlet of the cable bundle four.

[0015] Using the above structure, positioning is achieved through the auxiliary positioning wheel group two.

[0016] An air inlet is provided below the blower.
