Description

Technical Field

[0001] The utility model mainly relates to the technical field of extrusion equipment, in particular to a cable sheath material extrusion equipment. Background Art

[0002] Cables are usually rope-like cables formed by twisting several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation. At present, when cables are produced, it is necessary to put a cable sheath on the outside of the cable conductor to protect the cable conductor and avoid damage to the cable conductor, and it has an insulating effect. When producing the cable sheath, the raw material needs to be heated and melted and then introduced into the extrusion device for extrusion production.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] At present, there is a screw extrusion method, and the screw extrusion method is a fully enclosed mode, which is inconvenient to clean and maintain. Patent application number "202320047011.X" discloses a cable sheath material production extrusion device, which includes: an extrusion bin, the outer wall of the extrusion bin is fixedly installed with an annular heating bin, and one side of the inside of the extrusion bin is movably sleeved with a movable plate, and the movable plate is tightly fitted with the inner edge of the extrusion bin. The utility model can extract the screw mounted on the movable plate from the inside of the extrusion bin by placing a movable plate, a connecting plate, a mounting plate, and an electric push rod, so as to facilitate the cleaning of the inside of the extrusion bin and the surface of the screw. By setting an annular heating bin, a heating water tank, an air guide pipe and an air supply pipe, the water vapor generated by heating the water inside the heating water tank can be input into the bottom and both sides of the annular heating bin, and the water vapor is used to heat the extrusion bin, so that the extrusion bin is heated more evenly. At the same time, the cold water vapor condenses into water and flows back to the inside of the heating water tank to be repeatedly heated, avoiding the waste of water resources.

[0005] The above application is to remove the twin screws from the extrusion chamber to clean the screws. However, the production volume of cable sheaths is large and the screws need to be cleaned frequently. Frequent removal is inconvenient and easily causes damage to components.
