Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a cable extruder which is convenient for heating. Background Art

[0002] The cable manufacturing process includes the steps of raw material preparation, conductor production, insulation coating, braided armor, bite and sheath. The insulation coating requires a layer of insulation material to be wrapped on the outer surface of the cable to protect the cable. The cable extruder makes the insulation material into a molten state and then wraps it on the surface of the conductor. This step requires accurate temperature adjustment. If the temperature is not appropriate, it will affect the performance of the cable. Some existing cable extruders, when processing the outer skin of the cable, lack the corresponding insulation structure, resulting in a faster heat dissipation of the mixing drum, which is not conducive to the melting of the material, resulting in poor performance of the produced cable. At the same time, the temperature of the outer wall of the mixing drum is too high, which is prone to danger. In order to solve the above technical problems, this application provides a cable extruder that is easy to heat, which is not only convenient for heating the mixing drum, but also can accurately adjust the temperature of the mixing drum.

The raw materials are put into the mixing drum 7 through the feeding funnel 4, and the materials are heated and melted. The feeding switch 5 is used to control the amount of material fed each time.

[0020] like Figure 1 As shown, the mixing drum 7 is provided with a low temperature drum 1 7-1, a high temperature drum 7-2, and a low temperature drum 2 7-3 in sequence, the low temperature drum 1 7-1 is provided on the side close to the driving motor 3, the diameter of the low temperature drum 2 7-3 is smaller than the diameter of the high temperature drum 7-2, and the diameter of the high temperature drum 7-2 is smaller than the diameter of the low temperature drum 1 7-1. The high temperature drum 7-2 is provided with two, so that the melting of the material is more thorough and its stability is improved.

The temperature inside the high temperature cylinder 7-2 is higher than that of the low temperature cylinder 1 7-1 and the low temperature cylinder 2 7-3. The material is preliminarily heated in the low temperature cylinder 1 7-1, and then enters the high temperature cylinder 7-2 for further heating, shearing and stirring, and finally enters the low temperature cylinder 2 7-3 to reduce a certain temperature so that the material has a moderate hardness when it is extruded so that it can be coated on the outer surface of the cable.

The volume of the material in the low-temperature drum 1 7-1 and the high-temperature drum 7-2 is larger than the volume in the low-temperature drum 2 7-3, so that the material is more convenient to heat and melt, and the volume of the material at the output end is small, which is convenient for the extrusion of the material, so that it can be coated on the outer surface of the cable, thereby improving the stability of the cable.

[0023] like Figure 3 As shown, the side wall of the mixing drum 7 is provided with a heating layer 13, a heat preservation layer 12, and a protective layer 11 from the inside to the outside, and an electric heating coil 14 for heating is provided inside the heating layer 13.
