Description

Technical Field

[0001] The invention relates to the technical field of cable cooling, in particular to a cooling device for producing polyvinyl chloride cables. Background Art

[0002] PVC insulated cable and wire products are divided into unsheathed cables for fixed wiring, sheathed cables for fixed wiring, light unsheathed flexible cables, general purpose sheathed flexible cables, installation wires and shielded wires, special purpose sheathed flexible cables, PVC insulated flame retardant / fire-resistant cables and other products.

[0003] At present, the polyvinyl chloride insulation layer wrapped on the outside of the cable is mainly obtained by stretching the twisted cable outward from the hot-melt polyvinyl chloride material and shaping the hot-melt polyvinyl chloride through the end hole of the tube structure to achieve the standardization of the outer insulation layer of the twisted cable. However, as the cable is stretched outward after coating, the temperature of the insulation layer and its working environment will continue to rise. Once the coated cable is not cooled in time, the insulation layer on the outside of the cable will undergo secondary heat melting, which will seriously affect the quality of the cable. In addition, the cooling equipment used in the existing cable production process adopts air cooling and water cooling. The method of blowing on the tube structure will cause the internal temperature of the end hole of the tube structure to continue to decrease, which will cause the polyvinyl chloride to solidify. When the stretched cable is directly water-cooled, the high-temperature coating on the outside of the cable will undergo local shrinkage at the moment of entering the water, which will cause wrinkles in the coating on the outside of the cable.

[0004] When cooling cables coated with polyvinyl chloride, how to prevent the coating from shrinking during the cooling process of the cables that have been melted at high temperature and at the same time avoid shaping interference of traditional air cooling on the ports of the tube structure is a technical difficulty that needs to be solved by the present invention. Summary of the invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in the present invention is: A cooling device for polyvinyl chloride cable production, comprising a bearing air cooling mechanism, a secondary liquid cooling mechanism installed on the bearing air cooling mechanism, and a transmission mechanism installed on the secondary liquid cooling mechanism, wherein the bearing air cooling mechanism comprises a base and an air bin, the air bin is fixedly installed on a column on one side of the top of the base, a fan shaft movably installed in the air bin, a ring buckle fixed to the ends of two horizontal pipes outside the air bin by bolts, a plurality of groups of horizontal frames fixedly installed in the ring buckle and distributed in a circumference, two roller wheels movably installed between two adjacent horizontal frames, a bracket fixedly installed on the outer wall of the air bin, and a partition movably installed in the bracket, the secondary liquid cooling mechanism comprises two water tanks and a clamping plate filled with aqueous solution, two clamping rods located directly below the clamping plate, and a movably installed A linkage rod inside the two clamping rods, a boosting assembly installed between the two water tanks, two auxiliary wheels movably installed on the top of the inner cavity of the water tank, a main wheel movably installed at the bottom of the inner cavity of the water tank, a temperature-controlled exhaust pipe installed on the outside of the water tank and a coated cable running through the inner cavity of the water tank, the boosting assembly includes an end pipe for boosting water flow, two positioning members fixedly installed on the inner wall of the end pipe and a turbine shaft movably installed in the two positioning members, the transmission mechanism includes two sets of outer frames fixedly installed on the outer walls of the two water tanks, four auxiliary wheels movably installed in the two sets of outer frames, beams installed on two of the auxiliary wheels, a base fixed to a water tank with bolts, a motor fixed in the base and a crawler that transmits power to the motor and the beam.

[0007] In a preferred example, the present invention can be further configured as follows: a cylindrical pipe is installed in the middle of the wind bin, and a ventilation slot is opened at one end of the cylindrical pipe close to the fan blade shaft.

[0008] By adopting the above technical solution, a cylindrical pipe is installed in the middle of the wind bin. When the fan shaft is driven by the motor, the fan end inside the fan shaft will blow the external airflow toward the inside of the wind bin. At this time, the attracted airflow will be blown along the pipes on both sides of the wind bin. When the two coated cables pass through the two pipes on both sides of the wind bin, the directionally blown airflow inside the wind bin will initially shape the polyvinyl chloride on the outside of the two coated cables while performing pre-cooling treatment.

[0009] In a preferred example, the present invention can be further configured as follows: the blade shaft is composed of a gear plate, a blade end and an end rod, and the portion of the end rod close to the gear plate is a screw structure.

[0010] By adopting the above technical solution, the fan blade end in the fan blade shaft is passed through the warehouse pipe of the wind bin. When the two clamps position and clamp the end rod, as the motor starts and runs, the gear plate at the other end of the fan blade shaft will be driven, so that the air in the external environment can form a directional airflow to pre-cool the initially shaped coated cables. The two partitions on both sides of the wind bin will guide and blow the outwardly discharged airflow toward the surfaces of the two temperature-controlled exhaust pipes after being flipped over, so as to ensure that the heated aqueous solution on the inner wall of the water tank in the temperature-controlled exhaust pipe is cooled.

[0011] In a preferred example, the present invention can be further configured as follows: a waterproof pad is installed in the middle of the water tank, and holes are opened on both sides of the top of the water tank in a symmetrical manner to guide the delivery of the plated cables.

[0012] By adopting the above technical solution, a pad is installed in the middle of the inner cavity of the water tank. When the turbine shaft is driven and the aqueous solution in the inner cavity of the end tube is pressurized, the pressurized aqueous solution inside the end tube can circulate the aqueous solution inside the two water tanks. When the two water tanks and the two temperature-controlled exhaust pipes circulate the heated aqueous solution, the airflow guided by the two partitions will cool the two temperature-controlled exhaust pipes. At this time, it can ensure that the aqueous solution in the inner cavity of the two water tanks maintains a constant temperature at all times to cool the polyvinyl chloride on the coated cable.

[0013] In a preferred example, the present invention can be further configured as follows: a water inlet end pipe is opened in the middle of the outer side of the end pipe, and a sealing cover is installed on the outside of the water inlet end pipe.

[0014] By adopting the above technical solution and opening a water inlet end pipe on the end pipe, when the inner cavities of the two water tanks need to be refilled with aqueous solution, the operator can remove the sealing cover and connect the external water pipe to the water inlet end pipe until the aqueous solution flushes and fills the inner cavities of the two water tanks.

[0015] In a preferred example, the present invention can be further configured as follows: a pipe penetrating into the inner cavity of the water tank is installed at the bottom of the temperature-controlling drain pipe, and the outer end of the pipe at the bottom of the temperature-controlling drain pipe is connected to the outer end of the end pipe.

[0016] By adopting the above technical solution, using multiple thin tubes distributed in an array in the temperature-controlled drain pipe, when the aqueous solution in the water tank cavity is pressurized and cyclically drained along the thin tubes in the temperature-controlled drain pipe, the thin tubes are fully blown and cooled by the external airflow. At this time, the two temperature-controlled drain pipes can quickly cool the heated aqueous solutions in the inner cavities of the two water tanks to ensure that the subsequently stretched coated cables are cooled secondary.

[0017] In a preferred example, the present invention can be further configured as follows: a transmission end is installed on the external shaft of the motor, and a gear disc that transmits to the linkage rod is installed in the middle of the shaft.

[0018] By adopting the above technical solution, when the motor is started, the motor will drive the fan shaft, the linkage rod and the beam to rotate. At this time, the two auxiliary wheels fixed by the beam can reduce energy loss while rolling and transmitting the coated cable to improve the production operation of the coated cable coating shaping and cooling.

[0019] By adopting the above technical solution, the beneficial effects achieved by the present invention are: 1. The present invention installs a horizontal base on the outside of the port of the tube structure, installs a wind bin on the top of the base, and movably installs a horizontal fan blade shaft inside the wind bin, and simultaneously installs two ring buckles on the pipes at both ends of the wind bin. When multiple groups of cross frames are fixedly installed inside the ring buckles, multiple rollers movably clamped by the multiple groups of cross frames will pre-affect the secondary shaping constraints on the cable in a high-temperature state and its external coating. As the directional airflow generated in the inner cavity of the wind bin blows the polyvinyl chloride on the surface of the two coated cables inside it, the cable after the secondary shaping can be initially cooled. Finally, after the two coated cables enter the water tank, the cable after the secondary shaping will be cooled by continuous low-temperature water cooling, thereby effectively ensuring that the stretched cable is subjected to uniform specifications and precise shaping and cooling treatment, thereby avoiding the shrinkage of the polyvinyl chloride on the outside of the cable due to rapid cooling.

[0020] 2. The present invention installs two sets of symmetrically distributed external frames on the outside of two water tanks, and movably installs two symmetrically distributed auxiliary wheels in the two sets of external frames. When the motor is started and running, the external shaft of the motor will drive the track and the beam to rotate, and finally the two auxiliary wheels fixed at both ends of the beam will rotate along with it, and cooperate with the two adjacent sets of auxiliary wheels to roll the two coated cables. At this time, the device can control the delivery speed of the shaping and cooling of the two coated cables, thereby ensuring that the polyvinyl chloride on the outside of the two coated cables is accurately shaped.

[0026] Combination Figure 1-Figure 10 As shown, the present invention provides a cooling device for polyvinyl chloride cable production, comprising a load-bearing air cooling mechanism 100 , a secondary liquid cooling mechanism 200 installed on the load-bearing air cooling mechanism 100 , and a transmission mechanism 300 installed on the secondary liquid cooling mechanism 200 .

[0027] The air-cooling mechanism 100 includes a base 110, an air bin 120, a fan shaft 130, a bracket 140, a partition 150, a buckle 160, a cross frame 170 and a roller wheel 180. The secondary liquid cooling mechanism 200 includes a water tank 210, a clamping plate 220, a clamping rod 230, a linkage rod 240, a booster assembly 250, an auxiliary rotor 260, a main rotor 270, a temperature control exhaust pipe 280 and a coated cable 290.

The transmission mechanism 300 includes a base 310, a motor 320, an outer frame 330, an auxiliary wheel 340, a beam 350 and a crawler track 360.

[0028] Specifically, the wind bin 120 is fixedly mounted on a column on one side of the top of the base 110, the fan shaft 130 is movably mounted in the wind bin 120, the ring buckle 160 is fixed to the end heads of two horizontal tubes outside the wind bin 120 by bolts, a plurality of groups of horizontal frames 170 distributed in a circle are fixedly mounted in the ring buckle 160, two roller wheels 180 are movably mounted between two adjacent horizontal frames 170, the bracket 140 is fixedly mounted on the outer wall of the wind bin 120, the partition 150 is movably mounted in the bracket 140, the two clamping rods 230 are located directly below the clamping plate 220, the linkage rod 240 is movably mounted inside the two clamping rods 230, the booster assembly 250 is mounted between the two water tanks 210, and the two auxiliary wheels 260 are movably mounted on the bracket 140. The top of the inner cavity of the water tank 210, the main rotating wheel 270 is movably installed at the bottom of the inner cavity of the water tank 210, the temperature control exhaust pipe 280 is installed on the outside of the water tank 210, the coated cable 290 passes through the inner cavity of the water tank 210, the two positioning members 252 are fixedly installed on the inner wall of the end pipe 251, the turbine shaft 253 is movably installed in the two positioning members 252, the two groups of outer frames 330 are fixedly installed on the outer walls of the two water tanks 210, the four auxiliary wheels 340 are movably installed in the two groups of outer frames 330, the beam rod 350 is installed on two of the auxiliary wheels 340, the base 310 is fixed to a water tank 210 with bolts, the motor 320 is fixed in the base 310, and the crawler 360 is driven by the motor 320 and the beam rod 350.

[0029] By installing two ring buckles 160 on the pipes at both ends of the wind bin 120, when multiple sets of cross frames 170 are fixedly installed inside the ring buckles 160, multiple rollers 180 movably clamped by the multiple sets of cross frames 170 will pre-affect the secondary shaping constraints on the cables in a high-temperature state and their external coatings. As the directional airflow generated in the inner cavity of the wind bin 120 blows the polyvinyl chloride on the surface of the two coated cables 290 passing through it, the cables after the secondary shaping can be cooled for the first time. Finally, after the two coated cables 290 enter the water tank 210, the cables after the secondary shaping will be cooled by continuous low-temperature water cooling, thereby effectively ensuring To ensure that the stretched cables receive uniform and precise shaping and cooling treatment, thereby preventing the external polyvinyl chloride of the cables from shrinking due to rapid cooling, when the motor 320 is started and running, the external shaft of the motor 320 will drive the track 360 and the beam 350 to rotate, and finally the two auxiliary wheels 340 fixed at both ends of the beam 350 will rotate along with it, and cooperate with the two adjacent sets of auxiliary wheels 340 to roll the two coated cables 290. At this time, the device can control the delivery speed of the shaping and cooling of the two coated cables 290, thereby ensuring that the external polyvinyl chloride of the two coated cables 290 is accurately shaped. Embodiment 2:

[0030] Combination Figure 3 and Fig. 9 As shown, on the basis of Example 1, a cylindrical pipe is installed in the middle of the wind bin 120, and a ventilation slot is opened at one end of the cylindrical pipe close to the fan blade shaft 130. The fan blade shaft 130 is composed of a gear plate, a fan blade end and an end rod, and the part of the end rod close to the gear plate is a screw structure.

[0031] By installing a cylindrical pipe in the middle of the wind bin 120, when the fan shaft 130 is driven by the motor 320, the fan blade end inside the fan shaft 130 will blow the external airflow toward the inside of the wind bin 120, and the attracted airflow will be blown along the pipes on both sides of the wind bin 120. As the two coated cables 290 pass through the two pipes on both sides of the wind bin 120, the directional airflow inside the wind bin 120 will initially shape the polyvinyl chloride outside the two coated cables 290 and perform pre-cooling treatment at the same time. When the two clamps 220 position and clamp the end rod, as the motor 320 starts and runs, the gear plate at the other end of the fan shaft 130 will be driven. At this time, the directional airflow formed by the air in the external environment will pre-cool the initially shaped coated cable 290, and the two partitions 150 located on both sides of the wind bin 120 will guide and blow the outwardly discharged airflow toward the surface of the two temperature-controlled exhaust pipes 280 after flipping over, so as to ensure that the heated water solution on the inner wall of the water tank 210 in the temperature-controlled exhaust pipe 280 is cooled. Embodiment three:

[0032] Combination Fig. 9 and Fig.10 As shown, on the basis of embodiment one, a water-blocking pad is installed in the middle of the water tank 210, and holes are symmetrically distributed on both sides of the top of the water tank 210 to guide the delivery of the coated cables 290, a water inlet end pipe is opened in the middle of the outer side of the end pipe 251, and a sealing cover is installed on the outside of the water inlet end pipe, a pipe that passes through the inner cavity of the water tank 210 is installed at the bottom of the temperature control drain pipe 280, and the outer end of the bottom pipe of the temperature control drain pipe 280 is connected to the outer end of the end pipe 251.

[0033] By installing a pad in the middle of the inner cavity of the water tank 210, when the turbine shaft 253 is driven and pressurizes the aqueous solution in the inner cavity of the end pipe 251, the pressurized aqueous solution in the end pipe 251 can circulate the aqueous solution in the two water tanks 210. When the two water tanks 210 and the two temperature-controlled exhaust pipes 280 circulate the heated aqueous solution, the airflow guided by the two partitions 150 will cool the two temperature-controlled exhaust pipes 280. The aqueous solution in the inner cavity of the two water tanks 210 can always maintain a constant temperature to cool the polyvinyl chloride on the coated cable 290. When the inner cavity of the two water tanks 210 needs to be cooled, When refilling the aqueous solution in the tank 210, the operator can remove the sealing cover and connect the external water pipe to the water inlet pipe until the aqueous solution flushes and perfuses the inner cavities of the two water tanks 210, and finally makes the aqueous solution form a circulating flow state along the two water tanks 210 and the two temperature-controlled drain pipes 280. When the aqueous solution in the inner cavity of the water tank 210 is pressurized and cyclically drained along the capillary tubes in the temperature-controlled drain pipes 280, the capillary tubes are fully blown and cooled by the external airflow. At this time, the two temperature-controlled drain pipes 280 can quickly cool the heated aqueous solution in the inner cavities of the two water tanks 210 to ensure that the subsequently stretched coated cables 290 are cooled for the second time. Embodiment 4:

[0034] Combination Figure 7-10 As shown, on the basis of the first embodiment, a transmission end is installed on the external shaft of the motor 320, and a gear disc that transmits to the linkage rod 240 is installed in the middle of the shaft.

[0035] When the motor 320 is started, the motor 320 will drive the fan shaft 130, the linkage rod 240 and the beam 350 to rotate. At this time, the two auxiliary wheels 340 fixed by the beam 350 can roll and transmit the coated cable 290 while reducing energy loss to improve the production operation of the coated cable 290 that integrates coating shaping and cooling.

[0036] The working principle and use process of the present invention are as follows: two auxiliary wheels 260 are pre-movably installed on the top of the inner cavity of the water tank 210, and then the main wheel 270 is movably installed on the bottom of the inner cavity of the water tank 210, and then the temperature control exhaust pipe 280 is installed on the outer wall of the water tank 210, and the pipe at the bottom of the temperature control exhaust pipe 280 will penetrate into the interior of the water tank 210, and the outer end of the pipe at the bottom of the temperature control exhaust pipe 280 will be connected to the inner cavity of the end pipe 251, and the turbine shaft 253 is assembled in the interior of the end pipe 251 through two positioning members 252, and then the two clamping rods 230 are fixed between the two adjacent water tanks 210, and the linkage rod 240 is movably clamped by the two clamping rods 230, and the gear end at the bottom of the linkage rod 240 will penetrate into the inner cavity of the end pipe 251, and The gear at one end of the turbine shaft 253 is meshed for transmission, and then the two adjacent sets of auxiliary wheels 340 are movably assembled by using two sets of outer frames 330, and the end rods of the two auxiliary wheels 340 are welded to the two ends of the beam rod 350, and then the two assembled sets of outer frames 330 are respectively fixed on the outer walls of the two water tanks 210, and the holes on one side of the outer wall of the two adjacent auxiliary wheels 340 and the water tank 210 are horizontally symmetrical, and then the base 310 is fixedly assembled on the outside of a water tank 210 by bolts, and the motor 320 is fixed in the groove on the top of the base 310, and the crawler 360 drives the shaft rod outside the motor 320 with the linkage end in the middle of the beam rod 350, and then the two assembled water tanks 210 are fixed on the base by bolts. The top of the base 110 is then penetrated by the blade end of the blade shaft 130 into the interior of the wind bin 120, and the wind bin 120 is installed on the column on the top side of the base 110, and the multiple sets of cross frames 170 fixedly assembled by the buckles 160 will position and clamp the multiple roller wheels 180, and the multiple roller wheels 180 will be distributed in a circular state. When in use, the base 310 is started in advance. At this time, an airflow discharged outward will be generated inside the blade shaft 130, and when it is assisted by the multiple roller wheels 180 distributed in a circular state, the polyvinyl chloride coating on the outside of the coated cable 290 will be pre-cooled by air cooling under the action of the wide range of airflow. After the coated cable 290 enters the aqueous solution in the inner cavity of the water tank 210, it is driven by two auxiliary wheels 260 and the main wheel The coated cable 290 guided by the wheel 270 will be subjected to secondary liquid cooling by the aqueous solution flowing in the inner cavity of the water tank 210, and the linkage rod 240 driven by the motor 320 will pump the heated aqueous solution in the inner cavity of the end tube 251 toward the inside of a temperature-controlled drain pipe 280. With the cyclic filling of the heated aqueous solution in the inner cavities of the two water tanks 210 and the two temperature-controlled drain pipes 280, after the heated aqueous solution enters the temperature-controlled drain pipe 280 with a smaller diameter, the two inclined partitions 150 will guide the flowing airflow toward the two temperature-controlled drain pipes 280. At this time, the heated solution passing through the arrayed pipes in the temperature-controlled drain pipe 280 will be quickly cooled, thereby ensuring that the continuously delivered coated cables 290 can be subjected to low-temperature water cooling treatment after passing through the water tank 210.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
