Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable production equipment, and in particular to a flame-retardant wire and cable sheath extrusion device. Background Technology

[0002] The sheath of a wire or cable is the outermost protective layer of the wire or cable. Its main function is to protect the internal structure of the cable from the influence of the external environment, while also enhancing the cable's wear resistance and service life. However, in the wire and cable production process, an extrusion device is required to process the material, which can improve the material's performance in use. The processed material is then transported through the extrusion device. For example, a Chinese patent discloses an extrusion device for producing protective sheaths for wires and cables, with application number 202021982738.X. This device uses a separating air ring to create a gap between the tube wall and the extrusion sleeve, and high-pressure water is introduced through a cleaning pipe to clean the engagement groove and the outer wall of the screw. This facilitates the subsequent entry of material and prevents residual material from affecting the extrusion pipe's performance. However, during material replenishment, internal heat is easily lost, resulting in insufficient internal temperature, requiring reheating, which can affect the processing and molding of the internal material.

Rotating the handle 17 causes the connecting shaft 15 to rotate, thereby blocking the upper outlet of the second box 11 with the upper clamping plate 14 and causing the lower clamping plate 16 to rotate, opening the lower inlet of the second box 11. This allows for material replenishment while reducing internal heat loss.

[0024] The end of screw 6 away from motor 3 passes through the interior of processing cylinder 2 and extends into the interior of processing cylinder 2.

[0026] The end of the connecting shaft 15 away from the upper clamping plate 14 passes through the interior of the processing cylinder 2 and is rotatably connected to the processing cylinder 2. The upper clamping plate 14 and the lower clamping plate 16 are centrally symmetrically distributed. The shape of the upper clamping plate 14 and the lower clamping plate 16 matches the interior of the second box 11. The end of the connecting shaft 15 away from the lower clamping plate 16 is fixedly connected to a handle 17 to adjust the rotation direction of the connecting shaft 15. The handle 17 is provided with an anti-slip part on its exterior.

[0027] Working principle: First, the material is fed into the processing cylinder 2 through the first box 8. The motor 3 is started, which drives gear 4 to rotate gear 5. Gear 4 drives screw 6 to rotate, and gear 5 drives screw 7 to rotate, thus pushing the material forward. The heating rod 13 is connected to an external power source, which heats the inside of the processing cylinder 2, melting the material inside. When it is necessary to replenish the material, material is added into the second box 11. The handle 17 is turned, which rotates the connecting shaft 15, causing the upper clamping plate 14 to block the upper outlet of the second box 11. The lower clamping plate 16 rotates, and then the lower inlet of the second box 11 is opened, thus achieving material replenishment while reducing the loss of internal heat.
