UTILITY MODEL CONTENTS

[0004] The utility model provides a kind of cable sheath quick cooling machine to solve the problem that the cable can only be partially, locally cooled, leading to uneven cooling, ultimately affecting the performance and quality of the cable for the technical problems existing in the prior art.

[0005] The technical scheme for solving the above technical problems of the utility model is as follows: a kind of cable sheath quick cooling machine, comprising:

[0006] Cooling mode;

[0007] Through hole, the through hole is opened in the inside of cooling and is penetrated to the two sides of cooling mode;

[0008] Supporting shaft sleeve, the supporting shaft sleeve is arranged at one side of through hole;

[0009] Cooling channel, the cooling channel is arranged at the other side of through hole;

[0010] Liquid inlet hole, the liquid inlet hole is opened in the bottom of cooling mode, and is penetrated with through hole;

[0011] Liquid delivery pipe, one end of the liquid delivery pipe is arranged in liquid inlet hole, for pouring into cooling liquid in liquid inlet hole.

[0012] The utility model has the beneficial effects that:

[0013] 1) This device achieves a complete cooling process for cables by designing through holes in the cooling mold and setting support bushings and cooling channels on both sides of the holes. Coolant is injected into the inlet hole through the liquid delivery pipe, allowing the coolant to fill the entire cooling channel. This ensures that the cable is completely covered and immersed in the coolant in the cooling channel. With the continuous injection of coolant, the fluidity of the coolant is maintained. This not only effectively cools the cable but also cleans the surface of the cable. Moreover, the flowing coolant can avoid the weakening of the cooling effect caused by the gradual increase in temperature of the stagnant coolant. This ensures that the surface temperature of the cable drops rapidly, achieving a highly efficient and stable cooling effect. This effectively solves the shortcomings of traditional cooling methods and improves the quality and efficiency of cable production.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the cooling mold includes an upper mold and a lower mold that are detachably connected to each other, wherein the upper mold and the lower mold are distributed symmetrically in a mirror image about the central axis of the through hole.

[0016] The beneficial effects of adopting the above-mentioned further solution are that, since the upper and lower molds are detachably connected, operators can easily disassemble and assemble the molds, and can quickly replace the support bushings to adapt to the production of cables of different specifications and sizes, thereby improving the flexibility of the production equipment and reducing downtime caused by changes in specifications.

[0017] Furthermore, the other end of the liquid delivery pipe is connected to an external tap water pipe.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, by directly connecting to the external tap water pipe, cooling water can be supplied continuously, avoiding interruptions due to insufficient water storage capacity and maintaining the fluidity of the coolant.

[0019] Furthermore, the liquid inlet hole is located on the lower mold of the cooling mold.

[0020] Furthermore, a diversion sleeve is fixedly connected to one end of the support bushing near the cooling channel, wherein the central axis of the diversion sleeve is perpendicular to the central axis of the liquid delivery hole.

[0021] Furthermore, the drainage bushing is truncated cone-shaped, wherein the end of the drainage bushing with the smaller radial dimension extends into the cooling channel.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the truncated cone shape of the flow guide sleeve provides a natural ramp path, which guides the cooling water flowing out of the liquid delivery hole and into the cooling channel, allowing the cooling water to flow into the cooling channel accurately, reducing the possibility of water flow deviating from the target area and reducing unnecessary flow rate loss.

[0023] Further, the radial dimension of the inner side of the support sleeve is the same as the radial dimension of the cable. BRIEF DESCRIPTION OF DRAWINGS

[0028] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0029] In modern cable manufacturing processes, the cooling treatment of the cable sheath layer is one of the key steps to ensure product quality, and the traditional cooling method mainly adopts the passive cooling mode of cold water spraying and cold water pool.

[0030] However, in the cold water pool operation, in order to let the cable pass through, a notch is reserved in the pool wall, which causes the water level of the cold water to be lower than the notch position, and the cable cannot be completely covered, so that the cable can only be partially and locally cooled, resulting in uneven cooling, which ultimately affects the performance and quality of the cable. In addition, part of the equipment adopts guide equipment such as a supporting roller to maintain the immersion state of the cable in the cold water, and this method is easy to cause physical deformation of the cable, which further damages its quality. For this reason, the utility model person proposes a cable sheath layer rapid cooling machine to solve the above problems.

[0031] The utility model provides the following preferred embodiments

[0032] As shown in Figure 1 and Figure 2 , a cable sheath layer rapid cooling machine comprises:

[0033] A cooling mold;

[0034] A through hole is arranged in the interior of the cooling mold and penetrates both sides of the cooling mold;

[0035] A support sleeve is arranged on one side of the through hole;

[0036] A cooling channel is arranged on the other side of the through hole;

[0037] The liquid inlet hole is arranged at the bottom of the cooling mold and penetrates the through hole;

[0038] The liquid delivery pipe is arranged in the liquid inlet hole and used for pouring the cooling liquid into the liquid inlet hole.

[0039] The through hole is designed in the cooling mold, and the support sleeve and the cooling channel are arranged on both sides of the hole, realizing the complete cooling process of the cable. The cooling liquid is injected into the liquid inlet hole through the liquid delivery pipe, and the cooling liquid fills the entire cooling channel, so that the cable is completely covered and soaked by the cooling liquid in the cooling channel. With the continuous injection of the cooling liquid, the flowability of the cooling liquid is maintained, which not only effectively reduces the temperature but also cleans the outer surface of the cable. In addition, the flowing cooling liquid can avoid the phenomenon that the cooling effect is weakened due to the gradual increase of the temperature of the static cooling liquid, ensuring that the surface temperature of the cable is rapidly reduced and realizing the high-efficiency and stable cooling effect. The deficiencies of the traditional cooling method are effectively solved, and the quality and efficiency of the cable production are improved.

[0040] In this embodiment, as shown in Figure 1 and Figure 2 , the cooling mold includes an upper mold and a lower mold which are detachably connected to each other. The upper mold and the lower mold are arranged in a mirror image on the central axis of the through hole. Since the upper mold and the lower mold are detachably connected, the operator can easily disassemble and assemble the mold, and can quickly replace the support sleeve to adapt to the production of cables of different specifications and sizes, thereby improving the flexibility of the production equipment and reducing the downtime caused by specification changes.

[0041] In this embodiment, as shown in Figure 1 and Figure 2 , the other end of the liquid delivery pipe is in communication with an external tap water pipe. By directly connecting with the external tap water pipe, the cooling water can be continuously supplied, avoiding interruption caused by insufficient capacity of the water storage device and maintaining the flowability of the cooling liquid.

[0042] In this embodiment, as shown in Figure 1 and Figure 2 , the liquid inlet hole is arranged on the lower mold of the cooling mold.

[0043] In this embodiment, as shown in Figure 1 and Figure 2 , the support sleeve is fixedly connected with a drainage sleeve at the end close to the cooling channel. The central axis of the drainage sleeve is perpendicular to the central axis of the liquid delivery hole, and the drainage sleeve is in the shape of a truncated cone. The end of the drainage sleeve with a small radial dimension extends into the cooling channel. The truncated cone shape of the drainage sleeve provides a natural slope path, so that the cooling water flowing out of the liquid delivery hole is guided and flows into the cooling channel, reducing the possibility of water flow deviating from the target area and unnecessary flow rate loss.

[0044] In this embodiment, as shown in Figure 1 and Figure 2 The radial dimension of the inner side of the support shaft sleeve is the same as the radial dimension of the cable.

[0045] The specific working process of the utility model is as follows:

[0046] A through hole is designed in the cooling mold, and a support shaft sleeve and a cooling channel are arranged on both sides of the hole. After the cable extruder forms the cable, the cable is sequentially passed through the cooling channel and the support bearing. The liquid delivery pipe is used to inject cold water into the liquid hole. At the same time, the cold water fills the entire cooling channel, so that the cable is completely covered and soaked in the cold water in the cooling channel, so as to realize the cooling treatment of the cable jacket layer.

[0047] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
