AI Technical Summary
Traditional cooling devices used in the processing of thermoplastic flame-retardant polyethylene cable materials have a large temperature difference between the inside and outside during the cooling process, which causes tensile stress in the material, resulting in buckling, wrinkling or orange peel texture, affecting subsequent processing.
The system employs a multi-stage water tank design, with two sets of cooling water at different temperatures. First, high-temperature cooling water is used for initial cooling, followed by low-temperature cooling water for secondary cooling. Rubber pads prevent the materials from rubbing against the inner wall of the water-cooling tank, and absorbent cloths are used to clean water stains.
It effectively reduces the temperature difference between the inside and outside of the material, improves the cooling effect, prevents the outer skin of the material from cracking, and improves the processing quality.

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of wires; thermoplastic flame-retardant polyethylene cable is a type of cable that combines the flexibility and processability of polyethylene (PE) and flame-retardant performance, and is widely used in places with high fire safety requirements; the reasonable design and control of the cooling device is crucial to the material performance and production efficiency during the extrusion processing of thermoplastic flame-retardant polyethylene cable material.
[0003] The traditional cooling device for processing thermoplastic flame-retardant polyethylene cable material has the following disadvantages: in the use of the traditional cooling device for processing thermoplastic flame-retardant polyethylene cable material, the cable needs to be introduced into the water cooling tank for cooling.

When the stress exceeds the yield strength of the material, buckling wrinkles or orange peel-like textures are generated on the surface, affecting subsequent processing and use. Therefore, it needs to be improved. CONTENT OF THE UTILITY MODEL

[0030] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0031] As Figs. 1-6As shown, it shows a cooling device for thermoplastic flame-retardant polyethylene cable material processing in an embodiment of the present disclosure, comprising a water cooling tank 1, the right side of the water cooling tank 1 is provided with a table body 2 placed above the ground, the upper side of the table body 2 is provided with a steering mechanism 3, the inside of the water cooling tank 1 is welded with a partition plate 5, the inside of the water cooling tank 1 is provided with a positioning mechanism 4 located on both sides of the partition plate 5, the inside of both ends of the water cooling tank 1 is provided with a protection mechanism 6, the water temperature inside the front side of the partition plate 5 is higher than that inside the rear side of the partition plate 5, the positioning mechanism 4 comprises a rectangular plate 403 welded inside the bottom of the water cooling tank 1, the upper side of the rectangular plate 403 is uniformly bolted with a box body 404, the both ends of the upper side of the box body 404 is welded with a side plate 405, the inside of the side plate 405 is rotatably installed with a circular shaft 406, the outside of the circular shaft 406 is uniformly fixed with a positioning cylinder 407.
[0032] Wherein, the inside of both ends of the water cooling tank 1 is rotatably installed with two roller wheels two 401, the outside of the two roller wheels two 401 is fixedly sleeved with a positioning plate two 402, the gap is provided between the two roller wheels two 401;
[0033] In some examples, one end of the cable is passed through the protection mechanism 6 on the left front side of the water cooling tank 1, and then sequentially passes through the outside of the roller wheel two 401, the circular shaft 406, the protection mechanism 6 on the right front side and the roller wheel one 32, and then enters the protection mechanism 6 on the right rear side of the water cooling tank 1, and then sequentially passes through the protection mechanism 6 on the right rear side of the water cooling tank 1, the roller wheel two 401, the circular shaft 406 and the protection mechanism 6 on the left rear side, and then exits. Because the water temperature on the front side of the water cooling tank 1 is higher than that on the rear side of the water cooling tank 1, the water cooling tank 1 is first cooled by the cold water on the front side of the water cooling tank 1, and the material is limited by the positioning plate two 402 and the positioning cylinder 407, so that the material can move uniformly for cooling operation.
[0034] By setting two groups of cooling water with different temperatures to be injected into the inside of the water cooling tank 1, the material can first be cooled by the cooling water with a higher temperature, and then be cooled by the cooling water with a lower temperature. Compared with the traditional cooling device for thermoplastic flame-retardant polyethylene cable material processing, the cooling device for thermoplastic flame-retardant polyethylene cable material processing adopts a multi-section water tank to gradually reduce the water temperature, effectively improving the cooling effect of the material, and the rubber pad 62 can effectively prevent the material from being extruded and rubbed with the inner wall of the water cooling tank 1 to cause the outer skin to be broken, and the water stains on the surface of the water absorption cloth 64 can be cleaned, facilitating use.
[0035] As Figs. 1-4As shown, a cooling device for processing thermoplastic flame-retardant polyethylene cable material is illustrated in another embodiment of this disclosure. The protective mechanism 6 includes a triangular plate 61 bolted to the inner sides of both ends of the water cooling tank 1. A rubber pad 62 is glued to the top of the triangular plate 61. A round rod 63 threaded through the top of the triangular plate 61 extends to the outside of the rubber pad 62. An absorbent cloth 64 is movably sleeved on the outside of the round rod 63. A fixing plate 65 is welded to the top of the round rod 63. The radius of the fixing plate 65 is larger than the radius of the absorbent cloth 64 and it is located above the absorbent cloth 64.
[0036] In some examples, when the material passes between the inner sides of the absorbent cloth 64, the absorbent cloth 64 cleans water stains from the surface of the material, thus protecting the material.
[0037] like Figs. 1-6 As shown, a cooling device for processing thermoplastic flame-retardant polyethylene cable material is illustrated in another embodiment of this disclosure. The steering mechanism 3 includes a cover 31 welded above the platform 2. A roller 32 is rotatably mounted between the upper side of the platform 2 and the lower side of the cover 31. A positioning plate 33 is uniformly fixedly sleeved on the outer side of the roller 32. A mounting housing 34 is welded to the right side of the cover 31. A cross plate 36 is welded to the left side of the mounting housing 34. Air inlet slots 35 are uniformly opened on the right side of the mounting housing 34. A fan 37 is bolted to the left side of the mounting housing 34. There are two sets of fans 37. The two sets of fans 37 are respectively placed between the outer side of the cross plate 36 and the inner side of the mounting housing 34. Each set of fans 37 is located to the right of each roller 32.
[0038] In some examples, when the material passes through roller 32 for turning operations, fan 37 is activated to cool the material on the surface of roller 32. This not only cools the material but also dries the absorbent cloth 64 on the right side, thus effectively improving the cooling effect.
[0039] like Figs. 1-5 As shown, a cooling device for processing thermoplastic flame-retardant polyethylene cable material is illustrated in another embodiment of this disclosure. The number of positioning plates 402 is equal to the number of positioning cylinders 407, and the spacing between the positioning plates 402 is equal to the spacing between the positioning cylinders 407; the number of positioning plates 33 is equal to the number of positioning cylinders 407, and the spacing between the positioning plates 33 is equal to the spacing between the positioning cylinders 407; the number of round rods 63 is equal to the number of positioning cylinders 407, and the spacing between the round rods 63 is equal to the spacing between the positioning cylinders 407.
[0040] In some examples, the spacing and number of positioning plate 2 402, positioning cylinder 407, positioning plate 1 33 and round rod 63 are matched to enable simultaneous processing of multiple materials, improve the processing effect, and prevent materials from touching each other and affecting the molding effect.
[0041] The working principle and use process of the utility model:
[0042] One end of the cable is passed through the protection mechanism 6 on the left front side of the water cooling tank 1, and then sequentially passes through the outer side of the roller two 401, the circular shaft 406, the right front side protection mechanism 6 and the roller one 32, and then enters the protection mechanism 6 on the right rear side of the water cooling tank 1, and sequentially passes out of the protection mechanism 6 on the right rear side of the water cooling tank 1, the roller two 401, the circular shaft 406 and the protection mechanism 6 on the left rear side, because the water temperature on the front side of the water cooling tank 1 is higher than that on the rear side of the water cooling tank 1, so that the water cooling tank 1 is first cooled by the cold water on the front side of the water cooling tank 1, and the positioning plate two 402 and the positioning cylinder 407 limit the material, so that the material can be uniformly moved for cooling operation.
[0043] When the material passes between the inner sides of the water absorption cloth 64, the water absorption cloth 64 cleans the water stains on the surface of the material, and protects the material; when the material is turned by the roller one 32, the fan 37 is started at this time, so that the fan 37 air cools the material on the surface of the roller one 32, which not only cools the material, but also dries the water absorption cloth 64 on the right side, thereby effectively improving the cooling effect.
[0044] It should be noted that, in the present text, relational terms such as first and second and the like can only be used to distinguish one entity or action from another entity or action, without necessarily requiring or implying that there is any such actual relationship or order between these entities or actions. Moreover, the terms "comprises", "comprising", or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article, or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or inherent to such a process, method, article, or equipment.
