[0038] Working principle: Before the extrusion of wires and cables begins, a waterproof carriage is placed above the water tank near the machine head. A traction rope connects to the wire and cable ends via sliding rollers on the waterproof carriage, raising the joint between the wire and cable ends and the traction rope to prevent the wire and cable ends from contacting the water in the tank. Then, the machine is started to extrude the wires and cables. The waterproof carriage slides above the surface track of the water tank wall, propelled by the traction rope. Figure 1 ), to the cable car separator at the end of the water tank ( Figure 2 The baffle automatically separates from the cable, thus achieving a waterproof effect on the cable end. The waterproof cart running on the water tank is shown in the image below. Figure 1 .
[0039] During operation, the central axle and two support rods of the waterproof trolley ensure its stability. The outer sides of the outer baffles of the four wheels of the waterproof trolley are positioned close to the inner surface of the water tank wall, allowing the outer surfaces of the four wheels to move smoothly along the water tank wall without falling or veering off course. When the outer diameter of the cable is small, the waterproof trolley is placed at the end of the water tank near the machine head, and the cable connector can be placed directly on the sliding rollers of the waterproof trolley, with the traction rope on the connector directly pulling the waterproof trolley forward. When the cable's outer diameter is large, the waterproof trolley is placed at the end of the water tank near the machine head, with the cable connector suspended in the air and the traction rope placed on the sliding rollers of the waterproof trolley. After the extrusion eccentricity is adjusted, the operator holds the waterproof trolley through the handle in the handle hole until the traction rope, under power traction, pulls the connector onto the waterproof trolley via the sliding rollers. Then, the operator releases the handle, and the traction rope drags the waterproof trolley forward until the traction rope on the connector pulls the waterproof trolley forward to the baffle of the cable car separator. The trolley falls, and the cable continues to move forward with the traction rope, continuing normal production. If the cable's outer diameter is very large, the waterproof trolley cannot be placed at the end of the water tank near the machine head. Instead, it should be moved back appropriately in the direction of cable take-up on the production line. The backward distance must ensure that when adjusting the eccentricity, the connector will not cause eccentricity due to passing through the waterproof trolley, and the connector must always be on the water surface. Then, the same operation can be performed as when the cable's outer diameter is large.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
