TECHNICAL FIELD

[0001] The utility model relates to cable processing technical field relates to a kind of cooling device of cable extruder. BACKGROUND

[0002] Cable extruder is heated to the required temperature by heating system, so that raw materials such as plastic particles are melted and plasticized. The melted material is fed from the hopper into the extrusion chamber of the extruder through the rotation of the screw and the cylinder. Once the cable is extruded from the die, it is firmly pulled out by a pair of traction rollers or traction discs and cooled by a cooling device. The cable is cooled and shaped.

[0003] The cooling device of the cable extruder currently has a cooling chamber inside. Generally, cold water or cold air is injected into the cooling chamber to cool the cable inside. Cooling the outer wall of the cable with cold water will be completely wet. It takes a long time to dry the cable, so cold air is preferred for cooling the cable. However, the entire cooling chamber inside needs to be cooled down, which takes a long time and requires a large amount of cooling source. Therefore, there is an urgent need for a cooling device for cable extruder to solve the above problems. SUMMARY

[0026] Drying cavity 3 is equipped with drying assembly 9 for cable dehumidification.

[0027] As Figure 4As shown, the drying assembly 9 includes a pair of drying members symmetrically distributed along the cable, each of which includes an outer cover 91, a connecting rod 92, a heating pipe 93, an inner cover 94 and a water-absorbing sponge 95. The inner cover 94 is arranged inside the outer cover 91 and is in the shape of a semi-circular ring. The connecting rod 92 is provided with a plurality of rods and is uniformly fixed between the inner cover 94 and the outer cover 91. The heating pipe 93 is provided with at least one rod and is fixed to the inner wall of the outer cover 91. The water-absorbing sponge 95 is fixed to the inner wall of the inner cover 94. One of the outer covers 91 is fixed in the drying cavity 3 through a mounting rod, and the two outer covers 91 are detachably connected (inserted, clamped, etc.).

[0028] As shown in Figure 2 The drying cavity 3 is fixed with an electric cylinder 10 at the top. The output end of the electric cylinder 10 is fixed to the top of the outer cover 91.

[0029] The working principle of the cooling device is as follows:

[0030] The water inlet pipe 14 can be connected to a tap water pipe, and the water outlet pipe 13 can be inserted into a water storage bucket to collect the heated water. The tap water pipe and the water outlet pipe 13 are both provided with electromagnetic valves. The electromagnetic valves, the heating pipe 93, the electric cylinder 10 and the air pump 15 are electrically connected to the PLC controller 11. The PLC controller 11 can be used to preset the working interval time of the electromagnetic valves, the heating pipe 93 and the air pump 15, and to control the start and stop of the electric cylinder 10. The outer wall of the cold water tank 12 is provided with a cover plate 18 through an opening. The cover plate 18 can be opened regularly to add ice blocks to the cold water tank 12. When it is necessary to add water to the cold water tank 12, the electromagnetic valve on the tap water pipe is started by clicking the PLC controller 11. The water with a certain pressure in the tap water pipe will flow into the water inlet pipe 14 and then into the cold water tank 12. When the water in the cold water tank 12 reaches 70% (the water quantity can be set according to the actual situation), the electromagnetic valve on the tap water pipe will be closed. The cold water and the ice blocks are mixed together to reduce the temperature of the water. Of course, the cold water tank 12 can also be provided with a refrigeration system in the prior art to cool the water.

[0031] Before the device is used, the two drying pieces are in a separated state, the cable extruded by the cable extruder enters the three wire guide rings 6 in turn, the spiral cold air pipe 7 is sleeved outside the cable, then the air pump 15 is started, the air pump 15 will suck the external air into the air outlet pipe 16, the air is guided to the lower part inside the cold water tank 12 through the air outlet pipe 16, the air will be diffused in the cold water in the cold water tank 12, the air can be cooled, as the air pump 15 continuously sucks the air into the cold water tank 12, the cooled air (cold air) will flow into the two hoses 17, thus the cold air can be transported to the two ends of the spiral cold air pipe 7, as the cold air flow continues to flow, the cold air can flow from the two ends of the spiral cold air pipe 7 to the middle, and is uniformly sprayed on the cable through the plurality of air outlet holes 8, and in this process, the air pressure at the two ends of the spiral cold air pipe 7 is greater than the air pressure in the middle, achieving the purpose of strong cooling-weak cooling-strong cooling of the cable, which is beneficial to the rapid cooling and shaping of the cable, and makes the cable cooling and shaping effect better, since the spiral cold air pipe 7 is wrapped outside the cable, the surrounding of the cable will continuously maintain a relatively low temperature, without the need to cool the whole cooling cavity 2, which can save the cooling source;

[0032] When the cooled cable enters the drying cavity 3, the electric cylinder 10 is started to drive the lower drying piece to move downward, when the two drying pieces are attached together, the electric cylinder 10 is turned off, at this time, the outer net cover 91 is spliced with the outer net cover 91, the inner net cover 94 is spliced with the inner net cover 94, and the water absorption sponge 95 inside the inner net cover 94 is wrapped outside the cable (as shown in Figure 2 and 4 shown), the plurality of heating pipes 93 are powered on to heat the inside of the outer net cover 91, the heating pipes 93 are set by the PLC controller 11 to work for 5-7 minutes and then be intermittent for 3 minutes, so as to prevent the water absorption sponge 95 from being overheated and affecting its service life, the cooled cable outer wall will contain water, as the cable continuously moves, the water absorption sponge 95 will absorb the water on the cable, the heated water absorption sponge 95 has a certain temperature, which can make the water absorption sponge 95 and the water on the cable evaporate, thereby achieving the purpose of drying the cable, the evaporated water will be diffused to the inside of the drying cavity 3 through the water absorption sponge 95, the inner net cover 94 and the outer net cover 91, and finally diffused to the outside through the mesh plate 5. The setting of the connecting rod 92 not only fixes the outer net cover 91 and the inner net cover 94 together, but also makes the inside of the outer net cover 91 have a space for accommodating the heating pipes 93, under the use of the water absorption sponge 95 and the heating pipes 93, the water on the cable can be quickly removed.
