Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable production, in particular to a cable cooling device. Background Technique
[0002] A cable is usually a rope-like cable formed by stranding several or several groups of wires. The wires in each group are insulated from each other and are often twisted around a central wire. The whole is wrapped with a highly insulating covering layer, with the characteristics of conducting electricity inside and being insulated outside. During the cable manufacturing process, cooling the cable is a key link, which plays a crucial role in ensuring the quality and performance of the cable. In the insulation extrusion and sheath extrusion processes, the coating layer of the cable needs to be quickly cooled to avoid performance degradation and dimensional instability caused by overheating.
[0003] The existing cooling method usually soaks the cable in a coolant to achieve rapid cooling. However, due to the high temperature of the cable covering layer, when it enters the water tank and contacts the coolant, it will cause the temperature of the coolant around the cable to rise. Relying only on the natural flow of the coolant for heat exchange is likely to result in a relatively high local temperature, thus causing insufficient cooling and unable to well meet the requirement of rapid cooling, reducing the production quality of the cable. In view of this, this application proposes a cable cooling device. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a cable cooling device.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A cable cooling device includes a tank body. Grooves for conveying the cable are respectively opened at both ends of the tank body. Overflow boxes are respectively arranged at both ends of the tank body, and the two overflow boxes are respectively located below the corresponding grooves. Circulation pipes penetrate through the side walls of the two overflow boxes respectively. A plurality of bearing seats are symmetrically installed on the side wall of the tank body. A transmission rod is installed between the corresponding two bearing seats. A first guide wheel is sleeved at the center of the transmission rod. A plurality of paddle blades are arranged between the first guide wheel and the inner wall of the tank body. A plurality of through grooves are respectively opened on the plurality of paddle blades. A plurality of brackets are fixedly connected to the upper end of the tank body, and the plurality of brackets are respectively arranged opposite to the first guide wheel. Limiting devices are respectively arranged on the plurality of brackets. The first guide wheel and the limiting devices cooperate to realize the conveyance of the cable.
[0007] As a further preferred of this technical solution, a water outlet pipe communicating with the inside of the tank body penetrates through the bottom of the tank body. The water outlet pipe is communicated with the two circulation pipes through a three-way joint.
[0008] As a further preference of the technical solution, a side plate is provided on one side of the first guide wheel, and the radian R1 of the side wall of the side plate close to the first guide wheel is equal to the radian R2 of the wire groove opened on the first guide wheel, that is, R1 = R2.
[0009] As a further preference of the technical solution, the plurality of blades are commonly connected with a shaft seat, and the shaft seat is sleeved on the transmission rod through a key.
[0010] As a further preference of the technical solution, the limiting device includes two symmetrically arranged springs. The upper ends of the two springs are connected to the side wall of the bracket, and the lower ends of the two springs are respectively connected with assembly blocks. A second guide wheel is installed between the two assembly blocks.
[0011] As a further preference of the technical solution, the second guide wheels are respectively arranged above the corresponding first guide wheels, and the width L1 of the second guide wheel is smaller than the width L2 of the first guide wheel, that is, L1 < L2.
[0012] As a further preference of the technical solution, water inlet pipes are respectively installed on the side wall of the tank body through a plurality of fixing frames, and the water inlet pipes are respectively arranged between two adjacent first guide wheels.
[0013] The utility model has the following beneficial effects:
[0014] 1. By arranging the bearing seat and the transmission rod, when the first guide wheel and the second guide wheel convey the cable, the blades will be driven to rotate, thereby changing the flow path and velocity distribution of the coolant in the tank body, reducing the coolant temperature gradient around the cable, keeping the overall temperature of the coolant uniform, avoiding incomplete cooling caused by the increase in the temperature of the coolant near the cable, improving the heat exchange speed between the coolant and the cable surface, and thus taking away the heat of the cable covering layer faster, improving the cooling efficiency.
[0015] 2. The utility model pushes the coolant in the tank body towards the cable through the blades. The impact force transmitted by the coolant can clean the impurities adhered to the cable surface, and at the same time reduce the bubbles attached to the cable surface when the cable enters the coolant from the air, making the cable surface cleaner and smoother. When the cable production speed is relatively fast, the blades and the second guide wheel rotate synchronously, thereby pushing the coolant to maintain a suitable speed and pressure, and achieving the best cooling effect, improving the production quality and performance of the cable.

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0022] The present utility model provides a technical solution: As Figures 1-4 shown, a cable cooling device includes a trough body 1. Grooves 2 for conveying cables are respectively opened at both ends of the trough body 1. Overflow tanks 3 are respectively arranged at both ends of the trough body 1, and the two overflow tanks 3 are respectively located below the corresponding grooves 2. Circulation pipes 4 penetrate through the side walls of the two overflow tanks 3 respectively. A water outlet pipe 5 penetrating through the bottom of the trough body 1 and communicating with its interior is provided. The water outlet pipe 5 is communicated with the two circulation pipes 4 through a three-way joint. Further, by providing the overflow tanks 3 on both sides, the coolant flowing out of the grooves 2 can be collected and conveyed into the water outlet pipe 5 through the circulation pipes 4, improving the utilization rate of the coolant and avoiding waste of resources.
[0023] Water inlet pipes 16 are respectively installed on the side walls of the trough body 1 through a plurality of fixing frames, and the water inlet pipes 16 are respectively arranged between two adjacent first guide wheels 8. It should be noted that the coolant flows out of the water inlet pipes 16 through an externally connected pump set. Since the ports of the water inlet pipes 16 are inclined with respect to the trough body 1, a local water flow field will be formed in the trough body 1. At this time, the speed and direction of the water flow will change, making the flow direction of the coolant in the upper layer consistent with the flow direction of the coolant pushed by the rotation of the paddle 10, reducing the resistance received by the paddle 10 during rotation and improving the rate of heat and cold convection of the coolant.
[0024] On the side walls of the tank body 1, a plurality of bearing seats 6 are symmetrically installed. A transmission rod 7 is installed between two corresponding bearing seats 6. A first guide wheel 8 is sleeved at the center of the transmission rod 7. A side plate 9 is arranged on one side of the first guide wheel 8. The arc R1 of the side wall of the side plate 9 close to the first guide wheel 8 is equal to the arc R2 of the wire groove opened on the first guide wheel 8, that is, R1 = R2. It should be noted that when the paddle 10 pushes the coolant to flow, the thrust transmitted by the coolant makes the cable contact the side plate 9, which can limit the movement of the cable and improve the stability of cable transmission. By setting the contact surfaces with equal arcs, the cable is prevented from deforming, ensuring the production quality of the cable.
[0025] A plurality of paddles 10 are arranged between the first guide wheel 8 and the inner wall of the tank body 1. A plurality of through grooves 11 are respectively opened on the plurality of paddles 10. The plurality of paddles 10 are jointly connected with a shaft seat, and the shaft seat is sleeved on the transmission rod 7 through a key. Further, by the plurality of through grooves 11 opened on the paddles 10, during the rotation of the paddles 10, the resistance received by the paddles 10 can be reduced to a certain extent.
[0026] A plurality of brackets 12 are fixedly connected to the upper end of the tank body 1, and the plurality of brackets 12 are respectively arranged opposite to the upper part of the first guide wheel 8. Limiting devices are respectively arranged on the plurality of brackets 12. The first guide wheel 8 cooperates with the limiting devices to realize the transmission of the cable. The limiting device includes two symmetrically arranged springs 13. The upper ends of the two springs 13 are connected to the side walls of the brackets 12. The lower ends of the two springs 13 are respectively connected with fitting blocks 14. A second guide wheel 15 is installed between the two fitting blocks 14. The second guide wheels 15 are respectively arranged above the corresponding first guide wheels 8, and the width L1 of the second guide wheel 15 is smaller than the width L2 of the first guide wheel 8, that is, L1 < L2. It should be noted that under the elastic force of the springs 13, the second guide wheels 15 are pushed to contact the cable, which can be applicable to cables of different thicknesses, limit the transmission of the cable between the second guide wheels 15 and the first guide wheels 8, increase the friction between the cable and the first guide wheels 8, and ensure the stable rotation of the first guide wheels 8 during the process of pulling the cable.
[0027] The utility model provides a cable cooling device, and the specific working principle is as follows: The water outlet pipe 5 and the end of the water inlet pipe 16 away from the tank body 1 are connected to an external pump set to realize the circulation of the cooling liquid in the tank body 1. The cable enters the tank body 1 from the opened groove 2, is immersed in the cooling liquid in the tank body 1, and passes through between a plurality of arranged first guide wheels 8 and corresponding second guide wheels 15, and finally passes out of the groove 2 on the other side of the tank body 1 and is connected to an external traction device. Under the elastic force of the spring 13, the second guide wheel 15 is pushed to contact the cable, increasing the friction force between the cable and the first guide wheel 8, ensuring that the cable drives the first guide wheel 8 to rotate during the traction process, and at the same time playing a limiting role on the cable to prevent the cable from swinging during the conveying process. The arranged transmission rod 7 drives the paddle 10 on one side to rotate, and the paddle 10 can change the flow path and rate of the cooling liquid in the tank body 1, avoiding the local cooling liquid contacting the cable for a long time, resulting in the temperature rise of the cooling liquid near the cable and causing insufficient cooling. Along with the rapid flow of the cooling liquid, the heat exchange rate between the cable and the cooling liquid is accelerated, and the heat transferred by the cable is taken away faster, improving the cooling efficiency.
[0028] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the utility model.
