[0002] In the prior art, for example, the invention with application number 202010575405.3 discloses a cable extrusion production line and process. In order to solve the problem that the insulating layer wrapped around the outside of the wire will emit harmful smoke, as the wire is wound and stored by the winding device, a large amount of harmful smoke will still be present in the workshop and cannot be eliminated in time, and there is also a hidden danger of endangering the health of the workers and increasing the risk of occupational diseases. By setting up branch pipes and smoke exhaust pipes, the smoke generated by the insulation layer can be discharged to the outside through the smoke exhaust pipe, thereby reducing the possibility of harmful smoke endangering the health of the workers in the workshop. By setting up a feeding device, an extruder, a smoke exhaust device, a cooling device and a wire storage assembly, the harm of the working environment in the workshop to the health of the workers is reduced, and a complete extrusion processing flow is formed for the cable, thereby improving the processing efficiency of the wire and accelerating the production speed of the cable.
[0003] Similar to the above application, there are still some shortcomings:
[0004] In the process of cooling the cable, although circulating water cooling and air cooling are used to cool the cable, the water source flows in a straight line along the direction of the cable inside the cooling water tank, resulting in uneven water temperature inside the water tank. At the same time, the water flow cannot be cooled during the cooling process, which reduces the cooling rate. In addition, during the use of the device, more electrical equipment is used and the energy consumption is relatively large.
[0005] Therefore, an efficient cooling cable production extrusion process is designed to optimize the above problems. Summary of the invention

At the same time, a rotatable mesh cylinder is arranged in the middle section of the cooling water trough, and the cable passes through the middle. Guide plates are evenly arranged on the inner wall of the mesh cylinder, which can apply thrust to the guide plates when the water source passes through the inside of the mesh cylinder, thereby providing assistance for the rotation of the mesh cylinder, and also increasing the flow rate of water inside the mesh cylinder to ensure uniform Uniform cooling, in addition, rectangular frame plates are evenly installed on the outer wall of the net cylinder, and leakage holes are opened on the rectangular frame plates. During the rotation of the net cylinder, the water source can be lifted to increase the contact area with the air, thereby effectively cooling the water source in the middle section, thereby improving the cooling rate during use. By installing a first bevel gear on the lower guide wheel, and then using the second bevel gear at the end of the net cylinder, the movement of the cable is used to provide rotational power to the lower guide wheel, and the gear transmission method is used to control the rotation of the net cylinder.

It can effectively remove odors, and in the process of purifying toxic gases, the impact force of the falling reflux water is used as kinetic energy to control the operation of the exhaust assembly, and the toxic gas is extracted and transported to the interior of the box for purification, thereby improving the functionality of the device and being more energy-saving. The dewatering mechanism is composed of a roller, an upper receiving groove, a water-absorbing sponge roller, an annular groove, a rotating roller, a transmission gear and an air-drying component.

[0017] The present invention also provides an extrusion process for producing a cable with high efficiency cooling, comprising the following steps:
[0018] Step 1: The cable core passes through the inside of the die, and the melted plastic particles are extruded into the inside of the die through the extruder. After being coated on the surface of the cable core, they move toward the inside of the cooling water tank with the cable core;
[0019] Step 2: The cable enters the interior of the cooling water tank and passes through the spiral blades and the interior of the net cylinder. The reflux water pump draws water from the interior of the reflux water tank and injects it into the cooling water tank from the end away from the machine head. The water flows toward the machine head. The water is drained by the spiral blades and rotates around the cable. At the same time, the cable is in a continuous pulling state. The contact between the cable and the surface of the lower guide roller drives the first bevel gear to rotate. The first bevel gear cooperates with the second bevel gear to drive the net cylinder to rotate counterclockwise. The guide plate inside the net cylinder will also provide a certain amount of assistance to the rotation of the net cylinder under the impact of the water flow, and accelerate the flow of water during the rotation of the net cylinder. In addition, the rectangular frame plate lifts the water flow upward and flows down from the leak hole to increase the contact area with the air. The water source is cooled during the water cooling process to increase the cable cooling rate.
[0020] Step 3: Cooling water flows downward from the end close to the machine head, falls on the water wheel and controls the shaft to rotate. The rotation of the shaft generates negative pressure inside the protective shell. The suction pipe extracts gas from the inside of the exhaust assembly, and then extracts the irritating gas at the end of the machine head, and then discharges it into the inside of the box, using activated carbon for deodorization and purification;
[0021] Step 4: After cooling, the cable adheres to the upper surface of the upper guide roller and enters the upper receiving groove. The cable controls the rotation of the upper guide roller. The upper guide roller can provide power for the rotation of the lower guide roller through the pulley mechanism between the upper guide roller and the lower guide roller to ensure the stable rotation of the net drum. After the cable enters the upper receiving groove, it is pressed into the annular groove outside the water-absorbing sponge roller, which not only drives the rotation of the water-absorbing sponge roller, but also absorbs water. As the water-absorbing sponge roller rotates, the rotating roller squeezes out the water inside the water-absorbing sponge roller, and finally the cable passes through the inside of the ring.
[0022] Step 5: The purified and deodorized gas inside the box enters the second air cavity through the exhaust pipe, and then is discharged from the exhaust hole. The exhaust hole is tilted to blow toward the inside of the upper receiving slot, effectively preventing water stains from being discharged to the outside of the equipment while drying.
[0023] The beneficial effects of the present invention are:
[0024] The present invention provides an extrusion process for cable production with high efficiency cooling. Spiral blades are arranged at both ends of the cooling water tank, and the spiral blades are used to guide the water sources at both ends to change the flow direction of the water, so that the temperature of the cable is more uniform when entering and discharging, thereby ensuring the quality of the cable. At the same time, a rotatable mesh cylinder is arranged in the middle section of the cooling water tank, and the cable passes through the middle. Guide plates are evenly arranged on the inner wall of the mesh cylinder, and thrust can be applied to the guide plates when the water source passes through the inside of the mesh cylinder, thereby providing assistance for the rotation of the mesh cylinder and increasing the flow rate of the water inside the mesh cylinder to ensure uniform cooling. In addition, rectangular frame plates are evenly installed on the outer wall of the mesh cylinder, and leakage holes are opened on the rectangular frame plates. During the rotation of the mesh cylinder, the water source can be lifted up to increase the contact area with the air, thereby effectively cooling the water source in the middle section, thereby improving the cooling rate during use.
[0025] By installing a first bevel gear on the lower guide wheel and using it in conjunction with a second bevel gear at the end of the net drum, the movement of the cable is used to provide rotational power to the lower guide wheel, and the net drum is controlled to rotate by gear transmission. In addition, the water flow will also impact on the guide plate to assist the rotation of the net drum, making the rotation of the net drum more convenient and more energy-saving.
[0026] By arranging a box at the bottom of the cooling water tank, and filling the inside of the box with activated carbon, and then using the exhaust assembly composed of the shaft rod, water wheel, protective shell, fan blade, air suction pipe, cone cover, first air cavity, and air inlet hole on the lower receiving tank, it can effectively remove odors, and in the process of purifying toxic gases, the impact force of the falling reflux water is used as kinetic energy to control the operation of the exhaust assembly, extract the toxic gas and transport it to the inside of the box for purification, thereby improving the functionality of the device and being more energy-saving;
[0027] The dewatering mechanism is composed of a pressure roller, an upper guide roller, an upper receiving groove, a water-absorbing sponge roller, an annular groove, a rotating roller, a transmission gear and an air-drying component. The traction force when the cable is wound is used to control the rotation of the water-absorbing sponge roller to absorb water, and then the transmission gear is used to control the rotating roller to squeeze out the water inside the water-absorbing sponge roller. In addition, the air-drying mechanism is composed of a sleeve ring, a second air cavity, an exhaust hole and an exhaust pipe. The exhaust pipe is connected to the box on the deodorization mechanism, and the exhaust gas during purification can be used to air-dry the cable. A multi-linkage control method is adopted to reduce the use of electrical components, and the structure is compact, which reduces the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0037] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.
[0038] like Figure 1-Figure 8 As shown, the present embodiment provides an extrusion process for cable production with high efficiency cooling, including an extrusion device for the extrusion process, the extrusion device including an extruder 1, a head 2 installed at the output end of the extruder 1, and a cooling water trough 3 located at the discharge end of the head 2, a reflux water trough 4 is provided at the bottom of the cooling water trough 3 along the length direction, ventilation pipes 19 are evenly installed between the two sides of the reflux water trough 4, a lower receiving trough 5 is provided at the end of the reflux water trough 4 close to the head 2, a reflux water pump 6 is installed at the end of the reflux water trough 4 away from the lower receiving trough 5, a dewatering mechanism 7 is provided at the end of the cooling water trough 3 away from the head 2, flow guide components 9 are provided at both ends of the cooling water trough 3, a stirring and cooling mechanism 8 is provided at the middle position of the cooling water trough 3, and a deodorization mechanism 10 is provided between the bottom and the end of the cooling water trough 3.
[0039] The general working principle is as follows: during extrusion, plastic particles are injected into the interior of the extruder 1, and after being melted, they are injected into the interior of the machine head 2. At the same time, the cable core passes through the interior of the machine head 2. The plastic is coated on the outside of the cable core and then passes out with the cable core. The cable coating is completed and then enters the interior of the cooling water tank 3. The reflux pump 6 draws the water source inside the reflux tank 4 from the end away from the machine head 2 and injects it into the interior of the cooling water tank 3. The water inside the reflux tank 4 can be near the reflux pump 6. The technical solution in the prior art can be used to cool down the cable with cold water. The heated water falls into the interior of the reflux tank 4 from the end close to the machine head 2, and the water flows counterclockwise. Ring, and during reflux, due to the setting of the vent pipe 19, the contact area between the gas and the heat source can be increased to accelerate the cooling of the reflux water, so as to reduce the temperature of the reflux water when it enters the chiller, thereby reducing the electric energy consumed by the chiller. In the process of the cooling water flowing inside the cooling water tank 3, the water source is drained through the guide component 9 to ensure the uniformity of the water temperature. When passing through the middle section of the cooling water tank 3, the stirring and cooling mechanism 8 can not only accelerate the flow rate of the water, but also cool the water to a certain extent, thereby increasing the cooling rate. In addition, during the production process of the equipment, a certain amount of irritating gas will be generated at the head 2, and the deodorization mechanism 10 is used to absorb and purify the gas.
[0040] In this embodiment, the guide assembly 9 includes a lower guide roller 11 and a spiral blade 12. The lower guide roller 11 is evenly rotated and installed between the two sides inside the cooling water trough 3. The spiral blade 12 is fixedly installed at both ends inside the cooling water trough 3. The inner ring diameter of the spiral blade 12 is larger than the diameter of the cable, and the bottom of the inner ring of the spiral blade 12 is located on the same horizontal plane as the top of the lower guide roller 11.
[0041] Local working principle: the cable passes through the center of the spiral blade 12, and the bottom is attached to the top of the lower guide roller 11. The setting of the spiral blade 12 changes the traditional way of linear water transportation, forming a spiral water flow channel, which can rotate and move the water flow around the cable to ensure uniform water temperature.
[0042] In this embodiment, the stirring and cooling mechanism 8 includes a mesh cylinder 13, a rectangular frame plate 16, a leakage hole 17, a guide plate 18 and a driving unit. The mesh cylinder 13 is rotatably installed along the length direction of the cooling water trough 3 at the middle position inside the cooling water trough 3. The end of the mesh cylinder 13 is provided with a driving unit. The guide plates 18 are evenly installed on the inner wall of the mesh cylinder 13. The outer side of the mesh cylinder 13 is evenly fixed with a rectangular frame plate 16 along the circumferential direction. The rectangular frame plate 16 is parallel to the length direction of the mesh cylinder 13, and the rectangular frame plate 16 is evenly provided with leakage holes 17.
[0043] Local working principle: when water flows to the middle of the cooling water tank 3, the driving part will drive the mesh cylinder 13 to rotate in the circumferential direction, and the cable passes through the inside of the mesh cylinder 13, so the water flow rate inside the mesh cylinder 13 will be faster. At the same time, during the rotation of the mesh cylinder 13, the rectangular frame plate 16 will carry the moving water and rotate with the mesh cylinder 13. At the same time, the water will flow down from the inside of the leakage hole 17, increasing the contact area with the air, so as to cool the cooling water in the middle and improve the cooling rate of the cable.
[0044] In this embodiment, the driving part includes a first bevel gear 14 and a second bevel gear 15. The first bevel gear 14 is fixed on the lower guide roller 11 at the end of the net cylinder 13. The second bevel gear 15 is fixed on the outer side of the end of the net cylinder 13. The first bevel gear 14 and the second bevel gear 15 are meshed.
[0045] Partial working principle: Since the bottom of the cable fits with the lower guide roller 11, the pulling of the cable will control the rotation of the lower guide roller 11, and the lower guide roller 11 drives the first bevel gear 14 to rotate. Under the transmission control of the gear, the net cylinder 13 also rotates accordingly.
[0046] In this embodiment, the deodorization mechanism 10 includes a box body 20, activated carbon 21 and an exhaust assembly 22. The box body 20 is installed in the middle position of the bottom of the cooling water tank 3. The interior of the box body 20 is filled with activated carbon 21. The top of the lower receiving tank 5 is provided with an exhaust assembly 22 for transporting the gas at the end of the head 2 to the interior of the box body 20.
[0047] Partial working principle: During the production process, the exhaust component 22 will extract the irritating gas generated at the head 2, and then discharge it into the interior of the box 20, and use the activated carbon 21 to purify and deodorize it.
[0048] In this embodiment, the vacuum assembly 22 includes a shaft 23, a water wheel 24, a protective shell 25, fan blades 26, an air suction pipe 27 and an air suction part. The shaft 23 is rotatably installed between the two sides of the lower receiving groove 5. A water wheel 24 is fixed at the middle position of the shaft 23. The water wheel 24 is located below the water outlet at the end of the cooling water tank 3. Protective shells 25 are installed on both sides of the lower receiving groove 5.

The air suction part is located at the extrusion end of the machine head 2, and the air suction pipe 27 is connected to the air suction part.
[0049] Local working principle: During the circulation of water flow, when cooling water flows out, it only flows down from the opening at the inlet of the end of the cooling water tank 3 and gathers into one stream. When the water flows out, it has a faster flow rate. The cooling water falls from the cooling water tank 3 and impacts the surface of the water wheel 24, converting the kinetic energy and potential energy of the water flow into the power for the rotation of the water wheel 24. The water wheel 24 controls the rotation of the blades 26 at both ends of the shaft 23, generating negative pressure inside the protective shell 25, and drawing gas from the suction part at the end of the suction pipe 27 to absorb the irritating gas, and then discharges it into the interior of the box body 20 through the conduit.
[0050] In this embodiment, the air suction part includes a conical cover 28, a first air cavity 29 and an air inlet 30. The conical cover 28 is fixed on the top of the machine head 2. The open end of the conical cover 28 is close to the machine head 2. The conical cover 28 is coaxial with the machine head 2. The interior of the conical cover 28 is circumferentially provided with a first air cavity 29. The interior of the conical cover 28 is evenly provided with air inlet 30 that is connected to the interior of the first air cavity 29. The top end of the air suction pipe 27 is connected to the interior of the first air cavity 29.
[0051] Local working principle: During the production process, the open end of the conical cover 28 covers the discharge end of the machine head 2, the cable passes through the inside of the conical cover 28, and the irritating gas enters the inside of the first air cavity 29 through multiple groups of air inlet holes 30, and then enters the inside of the protective shell 25 through the suction pipe 27.
[0052] In this embodiment, the water removal mechanism 7 includes a pressure roller 31, an upper guide roller 32, an upper receiving groove 33, a water-absorbing sponge roller 34, an annular groove 35, a rotating roller 36, a transmission gear 37 and an air-drying component 38. The pressure roller 31 is rotatably installed above the lower guide roller 11 at one end of the cooling water tank 3 away from the machine head 2, the upper guide roller 32 is rotatably installed near the pressure roller 31, and the upper guide roller 32 is higher than the horizontal plane of the pressure roller 31, and the upper receiving groove 33 is installed at one end of the cooling water tank 3 away from the machine head 2, and the upper receiving groove 33 It is connected to the interior of the cooling water tank 3, and a water-absorbing sponge roller 34 is rotatably installed between the two sides of the upper receiving tank 33. An annular groove 35 is circumferentially provided at the middle position of the water-absorbing sponge roller 34, and a rotating roller 36 is rotatably installed below the water-absorbing sponge roller 34 and between the two sides of the upper receiving tank 33. The outer side of the rotating roller 36 squeezes the outer side of the water-absorbing sponge roller 34, and the ends of the water-absorbing sponge roller 34 and the rotating roller 36 are both installed with mutually meshing transmission gears 37, and an air-drying component 38 is provided at the end of the upper receiving tank 33.
[0053] Local working principle: After the cable is cooled, it passes through the pressure roller 31 and the lower guide roller 11. At this time, the pressure roller 31 limits the cable. Then the cable passes from the surface of the upper guide roller 32 into the interior of the upper receiving groove 33, and passes through the annular groove 35 on the outside of the water-absorbing sponge roller 34. The cable will be in the annular groove 35 and squeeze the water-absorbing sponge roller 34, so the two sides of the annular groove 35 will squeeze the cable to ensure the coverage effect on the cable surface, absorb the moisture on the cable surface, and control the rotation of the water-absorbing sponge roller 34 during the movement of the cable. The water-absorbing sponge roller 34 rotates in the opposite direction to the rotating roller 36 when rotating. The rotating roller 36 squeezes the water-absorbing sponge roller 34 to squeeze out the moisture inside it to ensure the water absorption effect on the cable surface. After absorbing water on the cable surface, the surface of the cable is dried by the air-drying component 38.
[0054] In this embodiment, the air-drying component 38 includes a ring 39, a second air cavity 40, an exhaust hole 41 and an exhaust pipe 42. The ring 39 is fixed at the end of the upper receiving groove 33 and is connected to the interior of the upper receiving groove 33. The second air cavity 40 is circumferentially opened inside the ring 39. The exhaust hole 41 connected to the interior of the second air cavity 40 is opened on the inner side of the ring 39. An exhaust pipe 42 is provided between the second air cavity 40 and the box body 20.
[0055] Local working principle: After being purified and deodorized by the activated carbon 21 inside the box 20, the gas with irritating gas will enter the inside of the second air cavity 40 from the exhaust pipe 42, and then be discharged evenly along the circumference of the cable from the exhaust hole 41. The surface of the cable is air-dried to avoid water stains on the outside of the equipment, and the cable coating is completed.
[0056] like Figure 1-Figure 8 As shown, this embodiment provides an extrusion process for producing a cable with high efficiency cooling as follows:
[0057] Step 1: The cable core passes through the interior of the die head 2, and the plastic particles are melted and extruded into the interior of the die head 2 through the extruder 1, and then coated on the surface of the cable core, and then move toward the interior of the cooling water tank 3 along with the cable core;
[0058] Step 2: The cable enters the interior of the cooling water tank 3, and passes through the spiral blades 12 and the mesh tube 13, and the reflux water pump 6 extracts the water source in the reflux water tank 4 and injects it into the cooling water tank 3 from the end away from the machine head 2. The water source flows toward the machine head 2, and the water source is drained by the spiral blades 12 and rotates around the cable. At the same time, the cable is in a continuous pulling state. The cable contacts the surface of the lower guide roller 11 to drive the first bevel gear 14 to rotate. The first bevel gear 14 cooperates with the second bevel gear 15 to drive the mesh tube 13 to rotate counterclockwise. The guide plate 18 inside the mesh tube 13 will also provide a certain amount of assistance to the rotation of the mesh tube 13 under the impact of the water flow, and accelerate the flow of water during the rotation of the mesh tube 13. In addition, the rectangular frame plate 16 lifts the water flow upward and flows down from the leak hole 17 to increase the contact area with the air. The water source is cooled during the water cooling process to increase the cable cooling rate;
[0059] Step 3: Cooling water flows downward from the end close to the machine head 2, falls on the water wheel 24 and controls the shaft 23 to rotate. The rotation of the shaft 23 generates negative pressure inside the protective shell 25. The suction pipe 27 extracts gas from the inside of the exhaust assembly 22, and then extracts the irritating gas at the end of the machine head 2, and then discharges it into the inside of the box 20, and uses the activated carbon 21 to deodorize and purify it;
[0060] Step 4: The cable after cooling is attached to the upper surface of the upper guide roller 32 and enters the upper receiving groove 33. The cable controls the rotation of the upper guide roller 32. The upper guide roller 32 can provide power for the rotation of the lower guide roller 11 through the pulley mechanism between the upper guide roller 32 and the lower guide roller 11 to ensure the stable rotation of the net drum 13. After the cable enters the upper receiving groove 33, it is pressed into the annular groove 35 on the outside of the water-absorbing sponge roller 34, which not only drives the rotation of the water-absorbing sponge roller 34, but also absorbs water. As the water-absorbing sponge roller 34 rotates, the rotating roller 36 squeezes out the water inside the water-absorbing sponge roller 34. Finally, the cable passes through the inside of the ring 39.
[0061] Step 5: The purified and deodorized gas inside the box body 20 enters the second air cavity 40 through the exhaust pipe 42, and then is discharged from the exhaust hole 41. The exhaust hole 41 is tilted to blow toward the inside of the upper receiving groove 33, effectively preventing water stains from being discharged to the outside of the equipment while drying.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
