Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable sheath extruder. Background Art

[0002] Extruder is a type of plastic machinery. According to the direction of the material flow in the die and the angle between the center line of the screw, the die head can be divided into right-angle die head and bevel die head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material and form it through the die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and the rare multi-screw extruders and screwless extruders.

[0003] At present, in the actual production process of cables, the cable surface needs to be coated and protected by a sheath extruder. Since the coating material itself has a very high temperature during the coating process, the cable needs to be cooled by a water tank after being output. However, the heat dissipation method of the water tank is mostly to cool the cable surface by dripping water through spraying water. It is found in the actual application process that this method of cooling cannot fully cool the cable, resulting in the bottom of the cable not being able to fully contact the water source for cooling, thereby affecting the overall cooling effect of the cable. Therefore, we make improvements to this and propose a cable sheath extruder. Utility Model Content

[0004] The utility model aims to provide a cable sheath extruder, which solves the problem that the existing cable sheath extruder cannot be fully cooled during use.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A cable sheath extruder comprises a wire-releasing mechanism, an extrusion mechanism and a cooling mechanism, wherein the wire-releasing mechanism, the extrusion mechanism and the cooling mechanism are all provided with a cable;

[0007] The cooling mechanism comprises a cooling water tank and a supporting roller;

[0008] The supporting roller has two portions which are respectively distributed on both sides of the cable and movably assembled with the inner side of the cooling water tank, and cooling elements are arranged on both sides of the supporting roller.

[0009] As a preferred technical solution of the present application, a guide space is formed between the two support rollers for supporting, guiding and cooling the cable.

[0010] As a preferred technical solution of the present application, the cooling element includes a supporting leg fixed in the cooling water tank and a cooling ring connected to the top of the supporting leg.

[0011] As a preferred technical solution of the present application, a guide ring is provided in an annular shape on the surface of the cooling ring, and a cooling nozzle is provided on the inner side of the cooling ring;

[0012] The plurality of cooling nozzles are distributed in an annular shape and are equidistantly arranged on the inner side of the cooling ring and are connected to the guide ring.

[0013] As a preferred technical solution of the present application, a joint is provided on the top of the guide ring, and a connecting pipe is connected to the joint.

[0014] As a preferred technical solution of the present application, the input ends of the connecting pipes in the plurality of cooling elements are commonly connected to a water pipe for connecting to an external water supply device.

[0015] The utility model realizes that when cooling the cable wrapped with the sheath, the cooling water source is transported to multiple cooling nozzles through the guide ring and sprayed out. Since multiple cooling nozzles are distributed along the circumferential direction of the cable, the cable can be fully contacted with the water source, which effectively improves the water spray cooling effect on the cable.

[0016] At the same time, with the setting of the guide space, the cable during transportation can be located at the center of the cooling ring, so that it can maintain a stable state during transportation, thereby improving the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the present invention to be protected, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 4 As shown, this embodiment provides a cable sheath extruder, comprising a wire-releasing mechanism 1, an extrusion mechanism 2 and a cooling mechanism 3, wherein the wire-releasing mechanism 1, the extrusion mechanism 2 and the cooling mechanism 3 are provided with a cable 4;

[0027] The cooling mechanism 3 includes a cooling water tank 31 and a support roller 32, wherein the support roller 32 has two cooling elements 5 respectively distributed on both sides of the cable 4 and movably assembled with the inner side of the cooling water tank 31, and cooling elements 5 are provided on both sides of the support roller 32;

[0028] A guide space 33 is formed between the two support rollers 32 for supporting, guiding and cooling the cable;

[0029] like Figure 4 As shown, two support rollers 32 are respectively arranged above and below the cable 4, so that the cable can be transported and guided at a fixed height under the support of the support rollers 32, thereby ensuring that the cable can be located at the center of the cooling element 5 during the actual transportation process, so that it can further fully contact with the water source, thereby achieving more comprehensive cooling;

[0030] By setting the cooling water tank 31, after the cooling element 5 cools the surface of the wrapped cable, the cooled water can be collected and then recycled for a second time after cooling.

[0031] As a further optimization of this embodiment: the cooling element 5 includes a support leg 51 fixed in the cooling water tank 31 and a cooling ring 52 connected to the top of the support leg 51;

[0032] A guide ring 53 is provided in an annular shape on the surface of the cooling ring 52, and a cooling nozzle 54 is provided on the inner side of the cooling ring 52;

[0033] A plurality of cooling nozzles 54 are distributed in an annular shape and at equal intervals on the inner side of the cooling ring 52 and are connected to the guide ring 53;

[0034] A joint 55 is provided on the top of the guide ring 53, and a connecting pipe 56 is connected to the joint 55;

[0035] In actual use, the connecting pipe 56 is connected to an external water source with a certain pressure, so that the water source with a certain pressure is input into the guide ring 53 through the connecting pipe 56 and the joint 55. Under the action of the guide ring 53, the multiple cooling nozzles 54 connected thereto are synchronously sprayed with water. The water is sprayed in different directions so that it can fully contact the surface of the cable 4, thereby ensuring the comprehensiveness of the surface temperature of the cable 4 and avoiding the situation of excessive local stability.

[0036] As a further optimization of this embodiment: the input ends of the connecting pipes 56 in the plurality of cooling elements 5 are commonly connected with a water delivery pipe 57 for connecting with an external water supply device;

[0038] The water pipe 57 is connected to an external water supply device (such as a water pump). By conveying a relatively low and stable external water source into the water pipe 57 and diverting it through a plurality of connecting pipes 56, the water is distributed in a plurality of guide rings 53 and sprayed out through a plurality of cooling nozzles 54, thereby achieving comprehensive and effective heat dissipation of the cable 4.
