[0014] Compared with the prior art, the present application has the following advantages:

[0015] I. The T-shaped plate is fixed and supported on the mold, the transmission wheel and the feeding wheel are coaxially connected on the T-shaped plate, the formed optical cable sheath is placed in the sliding groove between the transmission wheel and the feeding wheel and is in contact, the transmission wheel is driven by the motor to rotate around the axis, the feeding wheel is synchronously driven by the transmission wheel to move in the C direction, and the optical cable sheath between the transmission wheel and the feeding wheel is pulled and transported.

[0016] II. The transmission wheel is driven to rotate around the axis, the pull rod pushes the U-shaped frame and the sleeve block to move horizontally along the T-shaped plate under the action of the transmission wheel, the gear plate drives the rectangular slide to move back and forth along the inner wall of the rectangular frame under the support of the track plate, the rectangular frame is placed obliquely, and when the rectangular slide moves back and forth along the inner wall of the rectangular frame, the rectangular slide pushes the gear plate to move up and down along the inner wall of the track plate under the action of the rectangular frame, when the rectangular slide moves towards the fixed cylinder, the piston plate moves to the end of the rectangular slide close to the liquid inlet pipe, the internal pressure of the cavity close to the liquid inlet pipe is positive, the internal pressure of the cavity away from the liquid inlet pipe is negative, at this time, the first liquid inlet valve and the second liquid outlet valve are closed, the first liquid outlet valve and the second liquid inlet valve are opened, the liquid outlet pipe can spray the water source in the cavity close to the liquid inlet pipe to the surface of the optical cable sheath through the nozzle for cooling treatment, and the first connecting pipe can quantitatively extract the water source in the water tank to the inside of the cavity away from the liquid inlet pipe.

[0017] When the rectangular slider moves away from the fixed cylinder, the movement direction is opposite to the above structure, so that the internal air pressure of the cavity close to the one end of the liquid inlet pipe is negative pressure, and the internal air pressure of the cavity away from the one end of the liquid inlet pipe is positive pressure. At this time, the first liquid inlet valve and the second liquid outlet valve are in the open state, and the first liquid outlet valve and the second liquid inlet valve are in the closed state, so that the second connecting pipe can spray the internal water source of the cavity away from the one end of the liquid inlet pipe to the surface of the cable sheath through the liquid outlet pipe and the spray head for cooling, thereby realizing continuous spraying of the water source on the surface of the formed sheath during the extrusion process of the cable sheath, avoiding the residual heat of the cable sheath after extrusion, and the soft texture of the cable sheath, which is easy to cause the cable sheath to deform

[0018] III. The toothed plate reciprocatingly moves up and down on the track plate, so that the track plate can drive the cylindrical pipe to reciprocatingly rotate on the U-shaped frame under the action of the toothed plate. The polishing plate is arranged on the cylindrical pipe, and the sponge sandpaper is arranged on the polishing plate, so that the sponge sandpaper on the polishing plate is attached to the surface of the cable sheath. With the reciprocating rotation of the cylindrical pipe, the polishing plate polishes the surface of the cable sheath under the action of the cylindrical pipe, so that burrs, bubbles and cracks on the surface of the cable sheath are removed, and the quality and appearance of the cable sheath are improved.

[0019] Through the cooperation of the above structure, the problem that the existing device is difficult to cool the cable sheath after processing is solved. In the actual use process, because the cable sheath still has residual heat after extrusion, the cable sheath is soft in texture, which is easy to cause the cable sheath to deform, and the thickness is uneven, which affects the later use performance of the cable, so it is difficult to cool the cable sheath after processing.
