Description

TECHNICAL FIELD

[0001] The utility model relates to cable material production technical field, specifically point to a kind of granule cooling device for producing cable material. BACKGROUND

[0002] Cable material granule is a kind of prefabricated material for producing cable. When producing, polymer resin and additive are mixed well and then granulated by granulator. The granulator usually adopts hot cutting mode to extrude molten material into strip shape, and then cut into uniform size granules. The just-made granules are very high in temperature, and need to be cooled before packaging to prevent heat accumulation in the packaging bag from causing moisture and granule oxidation or even scrap.

[0003] The existing cable material granules are cooled by air cooling after production. The granulator directly feeds the produced granules into the cooling device with fan for cooling. Although the fan can accelerate the cooling of the granules, the cooling position is fixed, and the cooling efficiency is limited. Since the granules directly fall into the cooling device, they are prone to accumulate. During air cooling, only the surface layer of the granules can be cooled, and the cooling effect of the granules accumulated in the inner layer is not ideal, resulting in uneven cooling of the granules, which still cannot be directly packaged. SUMMARY

[0004] The utility model discloses to solve the above-mentioned various problems, propose a kind of granule cooling device for producing cable material with precooling structure, cooling efficiency is high, can automatically spread granule and realize uniform and sufficient cooling.

[0005] To solve the above technical problems, the technical scheme proposed by the utility model is: a kind of granule cooling device for producing cable material, including cooling frame, the cooling frame is rotationally connected with receiving tray, the receiving tray center lower part is equipped with discharge pipe, the receiving tray bottom surface is the center downward protruding conical net, the receiving tray is rotated by the rotation structure fixed on cooling frame and driven, receiving tray upper portion is equipped with drop hopper, the drop hopper lower portion is integrally formed with drop pipe, the drop pipe is close to receiving tray edge setting, the drop pipe outside is connected with cooling pipe, the cooling frame is connected with fan below receiving tray.

[0006] Further, the receiving tray upper portion edge is connected with protective ring, and the protective ring upper end is inclined to the center.

[0007] Based on the above features, the protective ring inclined at the upper end can effectively limit the cable material granules, prevent the granules from accidentally flying out of the receiving tray edge, ensure the cleanliness and safety of the production environment, and also avoid granule waste.

[0008] Further, the cooling frame comprises a bottom plate, a support leg is symmetrically connected above the bottom plate, a same fixing ring I is connected between the upper ends of the two support legs, and the receiving disc is rotationally connected in the fixing ring I.

[0009] Based on the above characteristics, the two symmetrically arranged support legs can provide stable support force for the fixing ring I, thereby ensuring the stability of the receiving disc.

[0010] Further, the rotating structure comprises a gear I connected to the outer wall of the discharging pipe, the gear I is meshed with a gear II on one side, and the gear II is driven by a motor fixed on the cooling frame.

[0011] Based on the above characteristics, the gear I cooperates with the gear II to ensure that the motor drives the receiving disc to rotate stably and continuously, thereby ensuring uniform paving of the granules.

[0012] Further, an L-shaped support is connected above the support leg near the discharging hopper, the other end of the L-shaped support is connected with a fixing ring II, and the discharging hopper is fixedly connected in the fixing ring II.

[0013] Based on the above characteristics, the L-shaped support and the fixing ring II provide firm support for the discharging hopper, so that the discharging hopper will not shake or shift due to the impact of the falling granules.

[0014] Further, the cooling pipe is spirally wrapped on the outer wall of the discharging pipe.

[0015] Based on the above characteristics, the spiral-shaped cooling pipe greatly increases the contact area with the discharging pipe, and can more fully absorb the heat of the granules during the falling process, thereby achieving efficient pre-cooling of the granules.

[0016] Further, the air outlet of the fan is located directly below the discharging pipe.

[0017] Based on the above characteristics, the air blown by the fan can directly act on the granules falling from the discharging pipe, which is conducive to improving the cooling effect.

[0018] Compared with the prior art, the advantages of this utility model are as follows: A spirally wrapped cooling pipe is connected to the outside of the discharge pipe. As the granules fall from the hopper through the discharge pipe, the cooling pipe pre-cools the granules, thereby improving the cooling efficiency. The bottom surface of the receiving tray is a cone-shaped mesh with a downward convex center, driven by a rotating structure. After the granules fall from the discharge pipe to the edge of the receiving tray, they automatically spread outwards as the tray rotates. This automatic spreading method ensures that the granules are evenly distributed on the receiving tray, achieving uniform cooling under the action of the fan. This avoids uneven cooling caused by granule accumulation. Furthermore, under the combined action of the inclined bottom surface of the receiving tray and the centrifugal force of rotation, the granules slowly enter the discharge pipe along the bottom surface of the receiving tray, effectively extending the cooling time and facilitating thorough cooling.
