Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cooling device for cable production. Background Technique

[0002] The cooling water tank in the cable production process is an important device, which is mainly used to cool and solidify the insulating layer or sheath layer of the cable to ensure the quality and performance of the cable product. The heat dissipation and temperature reduction are mainly achieved through the contact heat exchange between water and the cable.

[0003] In the prior art, a Chinese patent with the publication number of CN220548671 U discloses a cable circulating cooling water tank, including a support frame, a liquid inlet pipe, a cooling tank and a liquid outlet pipe; the cooling tank is connected to the support frame, a box body is arranged on the support frame, and the liquid outlet pipe is connected to the cooling tank and the box body; the liquid inlet pipe is connected to the box body and the cooling tank, a heat dissipation component is arranged on the support frame, and pump bodies are arranged on both the liquid inlet pipe and the liquid outlet pipe; a plurality of limiting components are arranged on the cooling tank, and inclined guide plates are arranged at both ends of the cooling tank. In the utility model, there is coolant in the box body, the pump body on the liquid outlet pipe pumps the coolant into the cooling tank, the pump body on the liquid inlet pipe pumps the coolant into the box body, and a heat dissipation component is arranged outside the liquid inlet pipe to make the coolant circulate and be used; the cable enters the cooling tank from one end of the cooling tank, and a plurality of limiting components on the cooling tank fix the cable inside the cooling tank, so that the cable is cooled more uniformly, and the arc-shaped notch on the guide plate is convenient for the cable to enter and exit the cooling tank.

[0004] However, in the actual use process, there are still some deficiencies in the above scheme. The sizes of cables in the production process are large and small. When there are problems in the traction during the process of moving the cable, some cables will be exposed above the liquid level. However, under the action of the spring, the pressure roller presses against the top of the cable. After long-term use, the pressure roller will deform the sheath on the outer surface of the cable, resulting in quality problems in the produced cable. Moreover, when pressing the smaller-sized cable, it will break, causing cost losses. In addition, the spring is always in a stretched state, and after long-term use, it will deform and experience stress relaxation, causing inconvenience in use. And there is a lack of a device for cooling the coolant in the box body. If the cable production speed increases, the flow rate of the coolant in the tank also needs to increase to ensure effective cooling of the cable. Only by using a cooling fan to dissipate heat from the liquid inlet pipe, the temperature of the coolant entering the box body is still too high and not easy to dissipate. Therefore, a cooling device for cable production is proposed to solve the above problems. Content of the Utility Model

It solves the problems that the sizes of cables are large and small during the production process, and when problems occur during the traction of the moving cable, some cables will be exposed above the liquid level. However, under the action of the spring, the pressure roller presses against the top of the cable.

When pressing a cable with a small size, it will break, causing cost losses. Moreover, the spring is always in a stretched state, and after long-term use, it will deform and experience stress relaxation, causing inconvenience in use. In addition, there is a lack of a device for cooling the coolant in the box. If the cable production speed increases, the flow rate of the coolant in the tank also needs to increase to ensure effective cooling of the cable.
