Example Embodiment

[0016] Example 1 : see figure 1 , high-efficiency cable material extrusion coating head, the coating head includes a head body 3, a die 6 arranged at one end of the head body, a guide rod 2 is arranged inside the head body, and the guide rod 2. A core wire 1 is arranged in the middle, and a covering plastic part 7 is arranged on the outer side of the die. The covering die also includes a porous plate 8, and the porous plate 8 is arranged below the die body 3. The guide rod 2 is provided with a shunt sleeve 10 and a pressure equalizing ring 11, and the number of the shunt sleeve 10 and the pressure equalizing ring 11 is at least one. The dead angle of the accumulated plastic; the pressure equalizing ring eliminates the pressure fluctuation during plastic extrusion. The whole technical scheme is ingeniously designed and compact in structure, which ensures the reasonable plastic flow channel in the machine head, eliminates the dead angle of accumulated plastic, and ensures the...

Example Embodiment

[0017] Example 2 : see figure 1 , as an improvement of the present invention, the coating head further includes an electric heater, which is arranged above the head body to properly heat the head body to further ensure the quality of the product. The rest of the structure and advantages are exactly the same as in Embodiment 1.

Example Embodiment

[0018] Example 3 : see figure 1 , as an improvement of the present invention, the coating head further includes an adjusting screw, the adjusting screw is arranged on the die, and the adjusting screw is used to adjust the tension of the die, and at the same time ensure the tightness between the die and the die core. Concentricity. The rest of the structure and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to an efficient cable material squeezing wrapping machine head which is characterized in that the wrapping machine head comprises a machine head body and an opening die arranged at one end of the machine head body. A guiding rod is arranged in the machine head body. A core wire is arranged in the middle of the guiding rod. A wrapping plastic part is arranged on the outer side of the opening die. The wrapping machine head further comprises a perforated plate which is arranged below the machine head body. A flow-dividing sleeve and a grading ring are arranged in the guiding rod. The numbers of the flow-dividing sleeve and the grading ring are at least one. The whole technology scheme is ingenious in design, the structure is compact, through the arrangement of a pushing rod, an embedded pushing rod can be lengthened according to practical needs, practicability and convenience are achieved, a pushing plate guiding sleeve and a guiding column are matched for use, so that a pushing-out process is stable, pushed parts cannot be bent or blocked, and practicability, flexibility and quickness are achieved.

Description

technical field [0001] The invention relates to an extrusion device, in particular to a high-efficiency cable material extrusion coating head, which belongs to the technical field of plastic molding equipment. Background technique [0002] Plastics for wire and cable insulation and sheathing cable material , including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. Cable sheathing is based on extrusion, and it has two types, vertical and horizontal. Among them, the horizontal angular extrusion method is the most commonly used. The equipment required for the whole process of cable processing is composed of pay-off device, extruder, coating die,...
