The stirring mechanism stirs the raw materials in the melt box through rotating stirring blades to ensure uniform mixing of the raw materials during the melting process to avoid uneven distribution of temperature and composition. At the same time, the stirring of the stirring mechanism helps prevent the raw materials from forming lumps or coking during the heating process, thereby ensuring the quality of the raw materials. The uniform melting of the raw materials also helps to improve the quality of the final extruded cable.

[0017] The extrusion tube can ensure that the raw materials are evenly wrapped on the core of the cable to form a uniform and continuous protective layer, and the inner wall of the extrusion tube can realize the rapid wrapping of the core, improve the production efficiency and ensure the quality of the cable.

The rapid cooling can shorten the production cycle and improve the production efficiency of the extruded cable. At the same time, the airflow generated by the fan helps to evenly cool the cable, reducing the inconsistent thickness of the insulation layer or stress concentration caused by uneven temperature. The uniform and efficient cooling helps to improve the physical and electrical properties of the cable insulation layer. Fan cooling is more energy-efficient than traditional water cooling, reducing energy consumption during the cooling process.

[0020] The invention relates to an extrusion device for processing photovoltaic cables. The use of a third motor allows the rotation speed of a rotating shaft and a traction wheel to be precisely controlled, thereby precisely controlling the traction speed of the wire core and ensuring the stability and consistency of the extrusion process.

[0035] In this embodiment, Figure 2 and Figure 6As shown, the feeding mechanism 6 is composed of a second motor 601 and a screw conveying rod 602, wherein one side of the second motor 601 is screwed to the inner wall of one side of the feed box 5, and the output end of the second motor 601 is plugged with the screw conveying rod 602; it should be noted that after the melted raw material is evenly stirred by the stirring mechanism 3, the operator can open the solenoid valve to connect the discharge channel 4 with the melt box 2. At this time, the raw material will enter the feed box 5 along the discharge channel 4 under the action of gravity. At the same time, the operator can start the second motor 601 to drive the screw conveying rod 602 plugged therein. The screw conveying rod 602 starts to rotate and pushes the raw materials around it to move toward the discharge pipe 501 to complete the raw material conveying operation. During this period, the screw conveying rod 602 rotates continuously under the drive of the second motor 601, which can realize the continuous conveying of raw materials and improve production efficiency.

One end of the spiral conveying rod 602 is rotatably connected to the inner part of the support rotating frame 502. It should be noted that when the operator starts the second motor 601 to drive the spiral conveying rod 602 to start rotating, the tail end of the spiral conveying rod 602 will also rotate inside the support rotating frame 502, and the raw materials gathered around the spiral conveying rod 602 will be pushed by it to move toward the discharge pipe 501, and finally along the discharge pipe 50 1 enters into the extruded package tube 701 connected thereto to wrap the wire core, and during this period, the support rotating frame 502 can provide stable support for the spiral conveying rod 602, reduce the vibration and deviation during its rotation, and ensure the continuity and uniformity of the conveying process, while the discharge pipe 501 serves as a passage for the raw materials from the feed box 5 to the extruded package tube 701, ensuring smooth conveying of the raw materials. At the same time, the discharge pipe 501 and the extruded package tube 701 are directly plugged in, which can reduce the contamination and impurity mixing of the raw materials during the conveying process and ensure the purity of the raw materials.

[0037] In this embodiment, Figure 3As shown, an extrusion tube 701 is provided inside the box body of the extrusion box 7, and a discharge tube 501 is plugged into one side of the extrusion tube 701; it should be noted that when the raw materials in the feed box 5 are pushed and transported to the discharge tube 501 by the feeding mechanism 6, the raw materials will follow the pipeline of the discharge tube 501 and enter the extrusion tube 701 plugged therewith. Before that, the operator can use the traction mechanism 11 to pass one end of the wire core from the entrance end of the extrusion tube 701 to its outlet end, so that there is a section of wire core in the extrusion tube 701, and when the raw materials enter the extrusion tube 701, the wire core inside it will be fully wrapped. At the same time, it is driven by the traction mechanism 11 to complete the extrusion operation of the core. During this period, the extrusion tube 701 can ensure that the raw materials are evenly wrapped on the core of the cable to form a uniform and continuous protective layer. The inner wall of the extrusion tube 701 can realize the rapid wrapping of the core, improve the production efficiency, and ensure the quality of the cable. At the same time, the design of the extrusion tube 701 is also helpful to ensure the thickness and quality of the insulation layer or sheath layer of the cable, and ensure the electrical performance and mechanical strength of the cable. The design of the extrusion tube 701 simplifies the extrusion process of the core, reduces the complexity of operation, and reduces the labor intensity of operators.

[0038] In this embodiment, Figure 4As shown in the figure, the clamping mechanism 8 is composed of a clamping ring 801, a silicone cushion 802, a compression spring member 803 and a resisting ring 804, wherein the resisting ring 804 is arranged at both the entrance and exit ends of the extrusion tube 701, one end of the compression spring member 803 is welded to the inner wall of the resisting ring 804, and the other end is welded to the outer wall of the clamping ring 801, and the silicone cushion 802 is arranged on the opposite side of the clamping ring 801; it should be noted that before the operator performs the extrusion operation, it is necessary to first pass one end of the wire core from the entrance end of the extrusion tube 701 to its exit end, and finally fix it at the traction mechanism 11, and during this period, the outer wall of the wire core will first pass between the clamping rings 801 on the left and right sides and contact them, at this time, the wire core will push the clamping ring 801 to both sides at the same time, and squeeze the compression spring member 803 arranged between the resisting ring 804 and the clamping ring 801, so that the distance between the clamping rings 801 on both sides is expanded, so as to be able to accommodate The entire wire core is allowed to pass through it, and in this process, the compression spring member 803 will push the middle wire core in the opposite direction through its characteristics, so that the silicone pad 802 arranged on the opposite side of the clamp ring 801 can fit tightly against the outer wall of the wire core, thereby completing the position definition of the entire wire core. In actual use, the clamping mechanism 8 fits tightly against the outer wall of the wire core through the clamp ring 801 and the silicone pad 802, which can ensure that the wire core maintains the correct center position during the extrusion process to avoid deviation, thereby reducing the waste of raw materials caused by inaccurate wire core position, and the stable wire core position is helpful to improve the uniformity of the extruded layer and the overall quality of the cable, and the use of the silicone pad 802 in the clamping mechanism 8 can reduce the wear on the surface of the wire core and protect the wire core from damage, and the setting of the compression spring member 803 can automatically adjust the spacing of the clamp ring 801 according to the diameter of the wire core to adapt to wire cores of different diameters.

[0039] In this embodiment, Figure 3 As shown, a fan 901 is clamped in the middle of the top wall of the cooling box 9; it should be noted that after the wire core is wrapped by the raw material in the extruded tube 701, the operator can simultaneously start the traction mechanism 11 to drive the wrapped wire core to pass through the retaining ring 804 at the outlet end of the extruded tube 701 and enter the cooling box 9. At the same time, the operator can start the fan 901 to make its blades start to rotate and drive the surrounding cold air to blow downward to the wire core, thereby cooling the insulating layer wrapped on its surface and quickly cooling it into shape. During this period, the fan 901 accelerates the cooling process of the cable insulation layer by blowing cold air, so that the cable insulation layer quickly solidifies and forms, and rapid cooling can shorten the production cycle and improve the production efficiency of the extruded cable. At the same time, the airflow generated by the fan 901 helps to evenly cool the cable and reduce the inconsistent thickness of the insulation layer or stress concentration caused by uneven temperature. The uniform and efficient cooling helps to improve the physical and electrical properties of the cable insulation layer, and the fan 901 cooling is more energy-efficient than the traditional water cooling method, reducing the energy consumption during the cooling process.

[0040] In this embodiment, Figure 1 and Figure 5 As shown, the traction mechanism 11 is composed of a support frame 1101, a third motor 1102, a traction wheel 1103 and a rotating shaft 1104, wherein the bottom of the support frame 1101 is arranged on one side of the top of the base plate 10, the left and right ends of the rotating shaft 1104 are closed and rotatably connected to the left and right inner walls of the support frame 1101, the traction wheel 1103 is sleeved on the outer wall of the rotating shaft 1104, and the output end of the third motor 1102 is plugged into one end of the rotating shaft 1104; it should be noted that when the operator needs to extrude the wire core, the operator can first pass one end of the wire core through the clamping mechanism 8 at the entrance end of the extrusion tube 701, and then pull the wire core to fix its end on the surface of the traction wheel 1103 in the traction mechanism 11, and in the process of the extrusion operation, the operator can start the third motor 1102, through its output end with The rotating shaft 1104 connected thereto starts to rotate, and the traction wheel 1103 sleeved on the outer wall of the rotating shaft 1104 will be rotated together with it, so as to reel in the wire core on its surface, thereby driving the wire core to stably pass through the extrusion tube 701. During this period, the use of the third motor 1102 allows the rotation speed of the rotating shaft 1104 and the traction wheel 1103 to be accurately controlled, so as to accurately control the traction speed of the wire core and ensure the stability and consistency of the extrusion process. The traction wheel 1103 can stably pull the wire core and reduce cable quality problems caused by uneven traction, such as uneven thickness of the insulation layer or deformation of the cable. The entire traction mechanism 11 can continuously pull the wire core and improve the production efficiency of the extrusion operation. At the same time, the automated traction mechanism 11 reduces the labor intensity of the operator and improves the convenience and safety of the operation.

[0042] like Figures 1 to 7As shown, first, the operator needs to pass one end of the wire core from the entrance end of the extruded tube 701 to its exit end. During this period, the outer wall of the wire core will first pass through and contact the clamping rings 801 on the left and right sides. At this time, the wire core will push the clamping rings 801 and the compression spring member 803 provided between the abutting ring 804 and the clamping ring 801 to both sides at the same time, so that the distance between the clamping rings 801 on both sides is expanded, so as to accommodate the entire wire core passing therethrough. In this process, the compression spring member 803 will reversely push the wire core in the middle through its characteristics. The core is made of a rubber rubber material 802, which is arranged on the opposite side of the clamp ring 801, so that the silicone pad 802 arranged on the opposite side of the clamp ring 801 can fit closely to the outer wall of the wire core, and the position of the entire wire core is defined. Then, the wire core is pulled and its end is fixed on the surface of the traction wheel 1103 in the traction mechanism 11. At this time, the operator can pour the raw material from the feed hopper 1 into the melt box 2, and start the electric heating tube 201 and the stirring mechanism 3 at the same time, wherein the electric heating tube 201 heats the raw material to melt, and the first motor 301 drives the stirring shaft 302 and the stirring blade connected thereto. 303 rotates together, thereby stirring and mixing the raw materials in the melt box 2. After the melted raw materials are evenly stirred by the stirring mechanism 3, the operator can open the solenoid valve to allow the raw materials to enter the feed box 5 along the discharge channel 4. At this time, the second motor 601 is started to drive the spiral conveying rod 602 connected thereto to start rotating, and push the raw materials around it to move toward the discharge pipe 501, and finally enter the extrusion tube 701 connected thereto along the pipeline of the discharge pipe 501 to wrap the wire core. During this period, the operator can start the third motor 1102 to drive the rotating shaft 1104 and the traction wheel 1103 to start rotating. At this time, the traction wheel 1103 will reel in the wire core on its surface, thereby driving the wire core to stably pass through the extrusion tube 701, and the wrapped wire core is pulled into the cooling box 9. At the same time, the operator can start the fan 901 to make its blades start rotating and drive the surrounding cold air to blow downward to the wire core, thereby cooling the insulating layer wrapped on its surface, so that it can be quickly cooled and formed.
