Cooling mechanism of a cable sheath extruder

Abstract

The present invention relates to the technical field of cable extrusion, and proposes a cooling mechanism for a cable sheath extruder, including a cooling device and a refrigeration device. The lower end of the cooling device is fixedly connected to a base, and collection devices are fixedly connected to both sides of the upper end of the base. A cycloidal device is fixedly connected to one side of the upper end of the base close to the cooling device, and an extrusion device is arranged on the left side of the right cycloidal device. The vibration is conducted to the cable wrapped with the upper sheath through the vibration wheel, so that after the cable wrapped with the upper sheath comes out of the cooling water, the water film on the cable sheath can be shaken and broken off, avoiding the water film from hindering heat conduction, resulting in internal cooling lag and affecting the consistency of the crystallinity of the insulating layer. Moreover, when the mechanical wave generated by the vibration propagates inside the material, the molecular kinetic energy is increased through phonon scattering, accelerating the heat conduction from the core to the surface and further improving the cooling uniformity.

[0015] The beneficial effects of the cooling mechanism of the cable sheath extruder provided by the present invention are as follows:

[0016] 1. After the cable wrapped with the sheath enters the cooling bin through the right-side limiting rollers, it is wound around the upper end of the vibration wheel and the lower end of the tensioning roller in sequence, thereby achieving step-by-step cooling. At the same time, start Motor 1, drive the bevel gear 1 to rotate through the bevel gear 2, drive the belt pulleys 2 on the front and rear sides to rotate through the drive shaft, thereby drive the belt pulley 1 on the left side to rotate through the transmission belt 2, and then drive all the belt pulleys 1 on the right side to rotate through the transmission belt 1, and then drive the spring and the knocking ball to rotate through the rotating shaft. When the knocking ball rotates to the upper end and hits the vibrating piece inside the upper part of the vibrating tube, the vibrating tube generates vibration, and the vibration is conducted to the cable wrapped with the sheath through the vibration wheel, so that after the cable wrapped with the sheath comes out of the cooling water, the water film on the cable sheath can be shaken and broken off, avoiding the water film from hindering heat conduction, resulting in internal cooling lag and affecting the consistency of the crystallinity of the insulating layer. And when the mechanical wave generated by the vibration propagates inside the material, the molecular kinetic energy is increased through phonon scattering, accelerating the heat conduction from the core to the surface, and further improving the cooling uniformity.

[0017] 2. When the belt pulley 1 drives the rotating shaft to rotate, it drives the tensioning roller to slide up and down in the inclined groove at the lower end of the cooling bin, thereby achieving the state that the cable is loose during vibration, ensuring the amplitude of the cable. Moreover, during the process that the tensioning roller slides to the bottom in the inclined groove, the cable is gradually tightened, and the amplitude is reduced until it stops, achieving the purpose of avoiding the cable sheath from being deformed due to the cable being in a vibrating state all the time.

[0028] The following combines the description drawings and embodiments to further describe the specific embodiments of the present invention in detail. The following embodiments are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] As Figures 1-8 shown, this embodiment proposes a cooling mechanism for a cable sheath extruder, including a cooling device 1 and a refrigeration device 5. The lower end of the cooling device 1 is fixedly connected to a base 6. On both sides of the upper end of the base 6, a collection device 2 is fixedly connected. On one side of the upper end of the base 6 close to the cooling device 1, a cycloidal device 3 is fixedly connected. On the left side of the right cycloidal device 3, an extrusion device 4 is arranged;

[0030] The cooling device 1 includes a cooling bin 11 and a drive shaft 113. Vibration tubes 12 are evenly distributed in the upper inner part of the cooling bin 11. A vibration piece 13 is fixedly connected to the upper inner end of the vibration tube 12. A rotating shaft 14 is rotatably connected to the middle inner part of the vibration tube 12. Springs 15 are evenly distributed at the left end of the rotating shaft 14. The left ends of the springs 15 are fixedly connected with knocking balls 16. Vibration wheels 129 are evenly distributed on the outer periphery of the vibration tube 12. Belt pulleys one 17 are fixedly connected to the front and rear ends of the rotating shaft 14. Adjacent belt pulleys one 17 are connected by a first drive belt 18. The front and rear belt pulleys one 17 on the left are connected to a belt pulley two 112 through a second drive belt 130. The inner circumferences of the belt pulleys two 112 are fixedly connected to both ends of the drive shaft 113. A first bevel gear 114 is fixedly connected to the outer periphery of the middle part of the drive shaft 113. The first bevel gear 114 is meshed with a second bevel gear 115. A first motor 116 is fixedly connected to the middle part of the second bevel gear 115.

[0031] In this embodiment, a drive bracket 117 is rotatably connected to the outer periphery of the drive shaft 113. The lower ends of the first motor 116 and the drive bracket 117 are fixedly connected to the middle part of the upper left side of the cooling bin 11. A second protective cover 119 is fixedly connected to the upper left side of the cooling bin 11. The lower ends of the front and rear sides of the second protective cover 119 are fixedly connected with a first protective cover 118. The sides of the first protective cover 118 close to the cooling bin 11 are fixedly connected to the front and rear sides of the cooling bin 11.

[0032] Specifically, when the cable wrapped with a sheath enters the cooling bin 11 through the right side of the limiting rollers 121, it is sequentially wound around the upper end of the vibration wheel 129 and the lower end of the tensioning roller 110, thereby achieving step-by-step cooling. At the same time, the first motor 116 is started, the second bevel gear 115 drives the first bevel gear 114 to rotate, the drive shaft 113 drives the belt pulleys two 112 on the front and rear sides to rotate, thereby driving the belt pulley one 17 on the left through the second drive belt 130, and then driving all the belt pulleys one 17 on the right through the first drive belt 18. Furthermore, the springs 15 and the knocking balls 16 are driven to rotate by the rotating shaft 14. When the knocking ball 16 rotates to the upper end and impacts the vibration piece 13 in the upper inner part of the vibration tube 12, the vibration tube 12 generates vibration, and the vibration is transmitted to the cable wrapped with a sheath through the vibration wheel 129. After the cable wrapped with a sheath comes out of the cooling water, the water film on the cable sheath can be shaken and broken off, avoiding the water film from hindering heat conduction, resulting in internal cooling lag and affecting the consistency of the crystallinity of the insulating layer. Moreover, when the mechanical wave generated by the vibration propagates inside the material, the molecular kinetic energy is increased through phonon scattering, accelerating the heat conduction from the core to the surface and further improving the cooling uniformity.

[0033] In this embodiment, tension rollers 110 are evenly distributed at the lower end of the cooling bin 11. At the lower ends of the six front and rear belt pulleys one 17 on the right side, crank shafts 19 are rotatably connected through rotating shafts. The lower ends of the crank shafts 19 are rotatably connected to the front and rear ends of the tension rollers 110. Sealing plates 111 are fixedly connected to the outer peripheries of the front and rear ends of the tension rollers 110. The sides of the sealing plates 111 close to the cooling bin 11 are slidably connected to the lower end of the cooling bin 11. The lower ends of the front and rear sides of the tension rollers 110 are slidably connected to the front and rear side chutes at the lower end of the cooling bin 11.

[0034] In this embodiment, limit seats 120 are fixedly connected to the upper ends of the left and right sides of the cooling bin 11. Limit rollers 121 are rotatably connected to the upper and lower ends of the middle part of the side of the limit seats 120 away from the cooling bin 11. The lower end of the cooling bin 11 is fixedly connected to the middle part of the upper end of the base 6.

[0035] Specifically, when the belt pulley one 17 drives the rotating shaft 14 to rotate, by driving the tension roller 110 to slide up and down in the inclined groove at the lower end of the cooling bin 11, the cable is in a slack state during vibration, ensuring the amplitude of the cable. Moreover, during the process of the tension roller 110 sliding to the bottom in the inclined groove, the cable is gradually tightened, reducing the amplitude until it stops, thus avoiding the cable sheath from deforming due to the cable being in a vibrating state all the time.

[0036] In this embodiment, refrigeration pipes 124 are fixedly connected to both inner sides of the cooling bin 11. The rear ends of the refrigeration pipes 124 are communicated with the front end of the refrigeration device 5. A water pump 122 is fixedly connected to the lower right corner of the front end of the cooling bin 11. The right water inlet end of the water pump 122 is communicated with the lower right corner of the cooling bin 11. The left water outlet end of the water pump 122 is communicated with a conduit 123. The left end of the conduit 123 is communicated with the lower left corner of the front side of the cooling bin 11.

[0037] In this embodiment, partition plates 125 are evenly distributed in the lower inner part of the cooling bin 11. Drainage troughs 126 are fixedly connected to the right ends of the three partition plates 125 on the left side. Water outlet holes one 127 are evenly distributed at the upper right side of the drainage troughs 126. Water outlet holes two 128 are evenly distributed at the lower inner part of the drainage troughs 126.

[0038] Specifically, the refrigeration device 5 preliminarily cools the hot water through the refrigeration pipe 124 on the right side, and then sends the preliminarily cooled clear water into the left side inside the cooling bin 11 through the water pump 122 and the conduit 123 to be cooled again through the refrigeration pipe 124 on the left side. The cooled water enters the water bin on the right side of the partition plate 125 through the water guiding groove 126. After a part of the water is discharged through the first water outlet hole 127, another part is discharged through the second water outlet hole 128, and the remaining part is discharged from the right end of the water guiding groove 126 and mixed with the hot water at different positions inside the water bin between the two partition plates 125. Since the number of the first water outlet holes 127 arranged from top to bottom decreases, the number of the second water outlet holes 128 decreases successively 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 the water output at different positions inside the same water bin is different. The temperature of the cooling water inside the water bin decreases successively from right to left after mixing, and further realizes the gradual cooling of the cable sheath inside the same water bin.

[0039] In this embodiment, the collecting device 2 includes a collecting bracket 21. The upper ends of the collecting brackets 21 are rotatably connected with collecting shafts 22. The front ends of the collecting shafts 22 are fixedly connected with belt pulleys three 24. The belt pulleys three 24 are all connected with belt pulleys four 26 through transmission belts three 25. The middle parts of the belt pulleys four 26 are fixedly connected with motors two 27. The outer peripheries of the collecting shafts 22 are 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. The lower ends of the motors two 27 are fixedly connected to the lower sides of the fronts of the collecting brackets 21.

[0040] Specifically, the motor two 27 drives the transmission belt three 25 to rotate through the belt pulley four 26, and then drives the collecting roller 23 to rotate through the belt pulley three 24 and the collecting shaft 22, completing the wire release of the cable core wire and the winding of the cable wrapped with the sheath.

[0041] In this embodiment, the wire laying device 3 includes a wire laying bracket 31 and a rack 34. The wire laying brackets 31 are evenly distributed on one side of the upper end far away from the cooling bin 11. The outer peripheries of the lower ends of the wire laying pipes 32 are fixedly connected with semi-gears 33. The semi-gears 33 are all meshed with the rack 34. The sides of the racks 34 close to the cooling bin 11 are fixedly connected with cylinders 35. The lower ends of the cylinders 35 are fixedly connected to one side of the upper end of the wire laying bracket 31 close to the cooling bin 11. The lower ends of the wire laying brackets 31 are fixedly connected to both sides of the middle part of the upper end of the base 6.

[0042] Specifically, start the cylinder 35, drive the semi-gear 33 to rotate reciprocally through the rack 34, and then evenly arrange the cable core wire and the cable wrapped with the sheath into the inside of the collecting roller 23 through the wire laying pipe 32.

[0043] In this embodiment, the extrusion device 4 includes an extrusion bracket 41. Extrusion bins 42 are fixedly connected to both the front and rear sides of the upper end of the extrusion bracket 41. Extrusion rollers 43 are rotatably connected to both sides inside the extrusion bins 42. Full gears 44 are fixedly connected to the sides of the extrusion rollers 43 away from the center of the base 6. The two full gears 44 mesh with each other. Reduction motors 45 are fixedly connected to the middle parts of the right full gears 44. Extrusion dies 46 are communicated with one side of the extrusion bins 42 close to the center of the base 6. Heating bins 47 are fixedly connected to the outer peripheries of the extrusion bins 42.

[0044] In this embodiment, the lower ends of the heating bins 47, the extrusion dies 46, and the reduction motors 45 are all fixedly connected to the upper end of the extrusion bracket 41. The lower end of the extrusion bracket 41 is fixedly connected to the middle right side of the upper end of the base 6.

[0045] Specifically, the cable core wire on the outer periphery of the right collecting roller 23 is threaded into the extrusion holes of the extrusion die 46 and connected to the traction wire of the left collecting roller 23. Raw materials are added into the extrusion bin 42. Motors 27, reduction motors 45, and heating bins 47 are started. The raw materials are heated and melted and extruded into the extrusion die 46, wrapping around the outer periphery of the cable core wire to form a sheath.

[0046] Working principle: First, thread the cable core wire on the outer periphery of the right collecting roller 23 into the extrusion hole of the extrusion die 46 and connect it to the towing wire of the left collecting roller 23. Add the raw material into the inside of the extrusion bin 42, start the second motor 27, the reduction motor 45 and the heating bin 47, heat and melt the raw material and extrude it into the extrusion die 46 to form a sheath wrapped around the outer periphery of the cable core wire. The second motor 27 drives the transmission belt three 25 to rotate through the fourth pulley 26, and then drives the collecting roller 23 to rotate through the third pulley 24 and the collecting shaft 22, completing the wire release of the cable core wire and the winding of the cable with the sheath. Then start the cylinder 35, drive the semi-gear 33 to rotate reciprocally through the rack 34, and then evenly arrange the cable core wire and the cable with the sheath into the inside of the collecting roller 23 through the swing tube 32. When the cable with the sheath enters the cooling bin 11 through between the right limiting rollers 121, it is wound around the upper end of the vibrating wheel 129 and the lower end of the tensioning roller 110 in sequence, thereby realizing step-by-step cooling. At the same time, start the first motor 116, drive the first bevel gear 114 to rotate through the second bevel gear 115, drive the second pulleys 112 on the front and rear sides to rotate through the drive shaft 113, thereby drive the left first pulley 17 to rotate through the second transmission belt 130, and then drive all the first pulleys 17 on the right side to rotate through the first transmission belt 18, and then drive 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 vibrating piece 13 on the upper part inside the vibrating tube 12, the vibrating tube 12 generates vibration, and the vibration is transmitted to the cable with the sheath through the vibrating wheel 129, so that after the cable with the sheath comes out of the cooling water, the water film on the cable sheath can be shaken and broken off, avoiding the water film from hindering heat conduction, resulting in internal cooling lag and affecting the consistency of the insulation layer crystallinity. And when the mechanical wave generated by the vibration propagates inside the material, the molecular kinetic energy is increased through phonon scattering, accelerating the heat conduction from the core to the surface, further improving the cooling uniformity. When the first 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 bin 11, thereby realizing that the cable is in a slack state during vibration, ensuring the amplitude of the cable. Moreover, during the process of the tensioning roller 110 sliding to the bottom in the inclined groove, the cable is gradually tightened and the amplitude is reduced until it stops, realizing the avoidance of the cable sheath deformation caused by the cable being in a vibrating state all the time. At the same time, the refrigeration device 5 preliminarily cools the hot water through the right refrigeration pipe 124, and then sends the preliminarily cooled clean water into the left side inside the cooling bin 11 through the water pump 122 and the conduit 123 for secondary cooling through the left refrigeration pipe 124. The cooled water enters the water storage bin on the right side of the partition plate 125 through the water diversion trough 126, discharges a part through the first water outlet hole 127, and then discharges a part through the second water outlet hole 128, and the remaining part is discharged from the right end of the water diversion trough 126 and mixed with the hot water at different positions inside the water storage bin between the two partition plates 125. And because the number of the first water outlet holes 127 arranged from top to bottom decreases, and the number of the second water outlet holes 128 decreases from left to right in sequence,Moreover, there are two bends at the lower end of the partition plate 125. Due to the different water pressures inside the water tank, 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 successively from right to left, further realizing the gradual cooling of the cable sheath inside the same water tank.

[0047] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should all be covered within the scope of the claims of the present invention.
