[0021] In this embodiment, the outer periphery of the driving shaft 113 is rotatably connected to a driving bracket 117, the lower ends of the motor 116 and the driving bracket 117 are fixedly connected to the middle left portion of the upper end of the cooling bin 11, the upper left end of the cooling bin 11 is fixedly connected to a protective cover 2 119, the front and rear lower ends of the protective cover 2 119 are fixedly connected to a protective cover 1 18, and the side of the protective cover 1 18 close to the cooling bin 11 is fixedly connected to the front and rear sides of the cooling bin 11.

[0022] Specifically, after the cable wrapped in the upper sheath passes between the limiting rollers 121 on the right and enters the cooling chamber 11, it is sequentially wound around the upper end of the vibration wheel 129 and the lower end of the tensioning roller 110, thereby realizing step-by-step cooling. At the same time, the motor 116 is started, and the bevel gear 114 is driven to rotate through the bevel gear 115, and the front and rear pulleys 112 are driven to rotate through the driving shaft 113, thereby driving the left pulley 17 to rotate through the transmission belt 130, and then driving all the pulleys 17 on the right side to rotate through the transmission belt 18, and then driving the spring 15 and the knocking wheel 14 through the rotating shaft 14. The striking ball 16 rotates, and when the striking ball 16 rotates to the upper end and hits the vibration plate 13 at the upper part of the vibration tube 12, the vibration tube 12 vibrates, and the vibration is transmitted to the cable wrapped in the upper sheath through the vibration wheel 129, so that after the cable wrapped in the upper sheath comes out of the cooling water, the water film on the cable sheath can be broken and detached, thereby avoiding the water film hindering heat conduction, causing internal cooling lag, and affecting the consistency of crystallinity of the insulation layer. In addition, when the mechanical waves generated by the vibration propagate inside the material, the molecular kinetic energy is increased through phonon scattering, thereby accelerating the conduction of heat from the core to the surface, and further improving the cooling uniformity.

[0023] In this embodiment, tensioning rollers 110 are evenly distributed at the lower end of the cooling bin 11, and the lower ends of the six front and rear pulleys 17 on the right side are rotatably connected to the crank shaft 19 through a rotating shaft. The lower ends of the crank shaft 19 are rotatably connected to the front and rear ends of the tensioning roller 110, and the front and rear end peripheries of the tensioning roller 110 are fixedly connected to sealing plates 111. The side of the sealing plate 111 close to the cooling bin 11 is slidably connected to the lower end of the cooling bin 11, and the front and rear lower ends of the tensioning roller 110 are slidably connected in the front and rear side slide grooves of the lower end of the cooling bin 11.

[0024] In this embodiment, the upper ends of the left and right sides of the cooling bin 11 are fixedly connected to the limiting seat 120, and the upper and lower ends of the middle part of the side of the limiting seat 120 away from the cooling bin 11 are rotatably connected to the limiting roller 121, and the lower end of the cooling bin 11 is fixedly connected to the middle part of the upper end of the base 6.

[0025] Specifically, when the pulley 17 drives the rotating shaft 14 to rotate, it drives the tensioning roller 110 to slide up and down in the inclined groove at the lower end of the cooling chamber 11, so that the cable is in a loose state when vibrating, thereby ensuring the amplitude of the cable. In the process of the tensioning roller 110 sliding to the bottom in the inclined groove, the cable is gradually tightened to reduce the amplitude until it stops, thereby preventing the cable from being in a vibrating state all the time and causing deformation of the cable sheath.

[0026] In this embodiment, both inner sides of the cooling bin 11 are fixedly connected with refrigeration pipes 124, and the rear ends of the refrigeration pipes 124 are connected with the front end of the refrigeration device 5. A water pump 122 is fixedly connected with the lower right corner of the front end of the cooling bin 11, and the right water inlet end of the water pump 122 is connected with the lower right corner of the cooling bin 11. The left water outlet end of the water pump 122 is connected with a conduit 123, and the left end of the conduit 123 is connected with the lower left corner of the front side of the cooling bin 11.

[0027] In this embodiment, partition plates 125 are evenly distributed on the inner lower part of the cooling bin 11, and the right ends of the three partition plates 125 on the left are fixedly connected with water diversion grooves 126. Water outlet holes 127 are evenly distributed on the right upper end of the water diversion groove 126, and water outlet holes 128 are evenly distributed on the inner lower end of the water diversion groove 126.

[0028] Specifically, the refrigeration device 5 initially cools the hot water through the refrigeration pipe 124 on the right, and then sends the initially cooled clean water into the inner left side of the cooling bin 11 through the water pump 122 and the conduit 123 to cool it again through the refrigeration pipe 124 on the left, and the cooled water enters the water bin on the right side of the partition plate 125 through the water inlet trough 126. After a part of it is discharged from the water outlet hole 127, another part is discharged from the water outlet hole 2 128, and the remaining part is discharged through the right end of the water inlet trough 126 and mixed with the hot water at different positions inside the water bin between the two partition plates 125. Since the number of water outlet holes 127 decreases from top to bottom, the number of water outlet holes 128 decreases from left to right, and there are two bends at the lower end of the partition plate 125, the water pressure inside the water bin is different, so that different water outputs are achieved at different positions inside the same water bin. After mixing, the cooling water temperature inside the water bin decreases from right to left, further achieving gradual cooling of the cable sheath inside the same water bin.

[0029] In this embodiment, the collecting device 2 includes a collecting bracket 21, the upper end of the collecting bracket 21 is rotatably connected to the collecting shaft 22, the front end of the collecting shaft 22 is fixedly connected to a pulley three 24, the pulley three 24 is connected to a pulley four 26 through a transmission belt three 25, the middle of the pulley four 26 is fixedly connected to a motor two 27, the outer periphery of the collecting shaft 22 is evenly distributed with collecting rollers 23, the lower ends of the collecting brackets 21 are fixedly connected to both sides of the upper end of the base 6, and the lower ends of the motors two 27 are fixedly connected to the lower side of the front end of the collecting bracket 21.

[0030] Specifically, the motor 27 drives the transmission belt 3 25 to rotate through the pulley 4 26, and then drives the collecting roller 23 to rotate through the pulley 3 24 and the collecting shaft 22, thereby completing the unwinding of the cable core wire and the winding of the cable wrapped with the sheath.

[0031] In this embodiment, the cycloid device 3 includes a cycloid bracket 31 and a rack 34. The cycloid tube 32 is evenly distributed on the side of the upper end of the cycloid bracket 31 away from the cooling bin 11. The lower end periphery of the cycloid tube 32 is fixedly connected with a half gear 33. The half gears 33 are meshed with the rack 34. The rack 34 is fixedly connected with a cylinder 35 on the side close to the cooling bin 11. The lower end of the cylinder 35 is fixedly connected to the side of the upper end of the cycloid bracket 31 close to the cooling bin 11. The lower end of the cycloid bracket 31 is fixedly connected to both sides of the middle part of the upper end of the base 6.

[0032] Specifically, the cylinder 35 is started to drive the half gear 33 to reciprocate through the rack 34, and then the cable core wires and the cables wrapped with the sheath are evenly arranged inside the collecting roller 23 through the cycloidal tube 32.

[0033] In this embodiment, the extrusion device 4 includes an extrusion bracket 41, and the front and rear sides of the upper end of the extrusion bracket 41 are fixedly connected to the extrusion bin 42, and the inner sides of the extrusion bin 42 are rotatably connected to the extrusion rollers 43, and the side of the extrusion roller 43 away from the center of the base 6 is fixedly connected to the full gear 44, and the full gears 44 on both sides are meshed with each other. The middle part of the right full gear 44 is fixedly connected to the reduction motor 45, and the side of the extrusion bin 42 close to the center of the base 6 is connected to the extrusion mold 46, and the outer periphery of the extrusion bin 42 is fixedly connected to the heating bin 47.

[0034] In this embodiment, the lower ends of the heating chamber 47 , the extrusion die 46 and the reduction motor 45 are fixedly connected to the upper end of the extrusion bracket 41 , and the lower end of the extrusion bracket 41 is fixedly connected to the right side of the middle of the upper end of the base 6 .

[0035] Specifically, the cable core wire on the outer periphery of the right collecting roller 23 is passed through the extrusion hole of the extrusion die 46 and connected to the traction line of the left collecting roller 23, the raw material is added into the extrusion bin 42, the motor 27, the reduction motor 45 and the heating bin 47 are started, the raw material is heated and melted, extruded into the extrusion die 46, and wrapped around the outer periphery of the cable core wire to form a sheath.

[0036] Working principle: First, pass the cable core wire on the periphery of the right collecting roller 23 through the extrusion hole of the extrusion die 46, and connect it to the traction line of the left collecting roller 23, add the raw material to the inside of the extrusion chamber 42, start the motor 27, the reduction motor 45 and the heating chamber 47, heat and melt the raw material and extrude it into the extrusion die 46, wrap it around the periphery of the cable core wire to form a sheath, and the motor 27 drives the transmission belt 3 25 to rotate through the pulley 4 26, and then drives the collecting roller 23 to rotate through the pulley 3 24 and the collecting shaft 22, so as to complete the unwinding of the cable core wire and the winding of the cable wrapped in the sheath, and start the cylinder 35, drive the half gear 33 to rotate back and forth through the rack 34, and then evenly spread the cable core wire and the cable wrapped in the sheath through the cycloidal tube 32. The cables are arranged inside the collecting roller 23. After the cables wrapped with the upper sheath pass through the limiting rollers 121 on the right and enter the cooling chamber 11, they are wound around the upper end of the vibration wheel 129 and the lower end of the tensioning roller 110 in sequence, thereby realizing step-by-step cooling. At the same time, the motor 116 is started, and the bevel gear 114 is driven to rotate through the bevel gear 115, and the front and rear pulleys 112 are driven to rotate through the driving shaft 113, thereby driving the pulley 17 on the left side to rotate through the transmission belt 130, and then driving all the pulleys 17 on the right side to rotate through the transmission belt 18, and then driving the spring 15 and the knocking ball 16 to rotate through the rotating shaft 14. When the knocking ball 16 rotates to the upper end and hits the vibration plate 13 on the upper part of the vibration tube 12, the vibration tube 12 is produced. The vibration is generated and transmitted to the cable wrapped in the upper sheath through the vibration wheel 129, so that after the cable wrapped in the upper sheath comes out of the cooling water, the water film on the cable sheath can be broken and detached, thereby avoiding the water film hindering heat conduction, causing internal cooling lag, and affecting the consistency of crystallinity of the insulation layer. When the mechanical wave generated by the vibration propagates inside the material, the molecular kinetic energy is increased through phonon scattering, and the heat is accelerated to be conducted from the core to the surface, thereby further improving the cooling uniformity. When the pulley 17 drives the rotating shaft 14 to rotate, it drives the tensioning roller 110 to slide up and down in the inclined groove at the lower end of the cooling chamber 11, thereby realizing that the cable is in a loose state during vibration, thereby ensuring the amplitude of the cable, and the tensioning roller 110 gradually tightens the cable during the process of sliding to the bottom in the inclined groove. The cable is lowered and the amplitude is reduced until it stops, thereby preventing the cable from being in a vibrating state all the time and causing deformation of the cable sheath. At the same time, the refrigeration device 5 initially cools down the hot water through the refrigeration pipe 124 on the right, and then sends the initially cooled clean water to the inner left side of the cooling bin 11 through the water pump 122 and the conduit 123 to cool it again through the refrigeration pipe 124 on the left. The cooled water enters the water tank on the right side of the partition plate 125 through the water inlet trough 126, and a part is discharged from the water outlet hole 127, and then a part is discharged from the water outlet hole 2 128, and the remaining part is discharged through the right end of the water inlet trough 126, and mixed with the hot water at different positions inside the water tank between the two partition plates 125. In addition, since the number of water outlet holes 127 decreases from top to bottom, the number of water outlet holes 128 decreases from left to right.In addition, the lower end of the partition plate 125 has two bends, and the water pressure inside the water tank is different, so that the water output at different positions inside the same water tank is different. After mixing, the temperature of the cooling water inside the water tank decreases from right to left, further realizing the gradual cooling of the cable sheath inside the same water tank.
