[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is in use, by providing a circular plate, an extrusion wheel, a spring and a hollow plate, before the cable core is inserted into the extrusion mold, the cable core needs to pass between multiple extrusion wheels on one side, so that the outer wall of the cable core pushes the multiple extrusion wheels respectively, and the extrusion wheels drive the corresponding movable rods to move, and the movable rods drive the clamping blocks to move while compressing the corresponding springs, and the multiple springs are used to apply elastic force to the corresponding extrusion wheels, so that the multiple extrusion wheels are respectively attached to the outer wall of the cable core, thereby achieving preliminary limitation of the movement trajectory of the cable core, effectively avoiding the deviation of the cable core, resulting in the problem of exposed core of the subsequently formed photovoltaic cable.

[0015] 2. When the present invention is in use, by providing a fixed block, a torsion spring, a movable plate and a limiting wheel, before the cable core enters the extrusion mold and after passing through multiple extrusion wheels, it will enter the inside of the limiting frame and push the multiple groups of limiting wheels inside the limiting frame, so that the multiple groups of limiting wheels respectively push the corresponding movable plates to deflect, the movable plate drives the circular shaft to rotate, and the circular shaft drives the corresponding two blocks to respectively compress the corresponding torsion springs, and the multiple groups of torsion springs are used to provide elastic force, which cooperates with the multiple groups of extrusion wheels on the outside to further realize the positioning of the cable core.

[0029] Working principle: When the present application is in use, firstly, an external traction device is used to feed the photovoltaic cable core into the extrusion mold 10 and pass through the extrusion mold 10. During this period, the photovoltaic cable core first passes through multiple groups of extrusion wheels 28 and multiple groups of limiting wheels 16 on one side. When passing through multiple groups of extrusion wheels 28, the outer wall of the photovoltaic cable core will push multiple extrusion wheels 28 respectively, so that the extrusion wheels 28 drive the corresponding movable rods 26 to move. The movable rods 26 drive the block 25 to move while compressing the corresponding springs 27. Multiple springs 27 are used to apply elastic force to the corresponding extrusion wheels 28, so that the multiple extrusion wheels 28 are respectively attached to the outer wall of the photovoltaic cable core, thereby realizing the preliminary limitation of the moving trajectory of the photovoltaic cable core, effectively avoiding the deviation of the cable core, resulting in subsequent formation. The photovoltaic cable of this type has the problem of exposed core. After the photovoltaic cable core passes through multiple sets of extrusion wheels 28, it will push the multiple sets of limiting wheels 16 inside the limiting frame 13 again, so that the multiple sets of limiting wheels 16 respectively push the corresponding movable plate 15 to deflect, and the movable plate 15 drives the round shaft 17 to rotate, and the round shaft 17 drives the corresponding two stoppers 18 to compress the corresponding torsion springs 19 respectively. The multiple sets of torsion springs 19 provide elastic force and cooperate with the multiple sets of extrusion wheels 28 on the outside to further realize the positioning of the cable core. Through the cooperation of the two sets of positioning components, a better positioning effect is achieved. Then, the feed hopper 3 is used to inject the processed raw materials into the empty shell 1, and then the motor 4 and the electric heater 2 are driven. The electric heater 2 is used to quickly heat the raw materials inside the empty shell 1. At the same time, the motor 4 drives The rotating rod 5 rotates, and the rotating rod 5 drives the spiral blade 6 to rotate. The rotation of the spiral blade 6 pushes the raw material entering the empty shell 1, so that the raw material is pushed and enters the extrusion mold 10 along the connecting pipe 7. At this time, a large amount of raw material enters the annular groove 11 and slowly fills the annular groove 11. Then, it is discharged through the annular extrusion groove 12 and coated on the outer surface of the photovoltaic cable core to form an insulating sleeve. At this time, two water pumps 32 and multiple groups of fans 21 can be driven, one of which is a group of water pumps 32. The ice water in the water tank 29 is extracted, and the ice water is sent into the corresponding circulation pipe 35 along the corresponding multiple groups of water pipes 33, so that the circulation pipe 35 is affected by the ice water to reduce its own temperature and the surrounding temperature of the circulation pipe 35. At the same time, the driving of the multiple groups of fans 21 will be directed to An air flow is blown toward the extrusion die 10, and the blown air flow cooperates with the low temperature generated by the circulation pipe 35 to achieve rapid cooling of the formed photovoltaic cable, and after the ice water enters the circulation pipe 35, it is quickly pumped by another water pump 32 and enters the water tank 29, and is cooled again by the internal components of the water tank 29, so as to achieve the recycling of ice water and ensure the cooling effect, thereby effectively avoiding the problem of bulging of the photovoltaic cable after molding. The cooled and formed photovoltaic cable is continuously moved by the traction of the external traction equipment, which will push the multiple extrusion wheels 28 on the other side to move, and the extrusion wheels 28 drive the corresponding movable rods 26 to move. The movable rods 26 drive the block 25 to move while compressing the corresponding springs 27, and the multiple springs 27 are used to apply elastic force to the corresponding extrusion wheels 28.The multiple extrusion wheels 28 are respectively attached to the outer surface of the formed photovoltaic cable. The extrusion of multiple groups of extrusion wheels 28 can make the formed outer insulation layer and the cable core more closely and closely attached, thereby improving product quality.
