Description
Technical Field
The utility model belongs to cable extruder field, especially a cable sheathing rapid cooling device.
Background
The plastic insulation and sheathing of the cable is carried out by continuous extrusion, the extrusion equipment generally being a single screw extruder. Before the plastic is extruded, whether the plastic is wet or has other impurities is checked in advance, and then the screw is preheated and then is added into a hopper. In the extrusion process, the plastic loaded in the hopper enters the machine barrel by virtue of gravity or a feeding screw, is continuously pushed forward under the thrust action of a rotating screw, and gradually moves from the preheating section to the homogenizing section; meanwhile, the plastic is stirred and extruded by the screw, and is converted into a viscous state under the action of external heat of the machine barrel and shearing friction between the plastic and equipment, so that a continuous and uniform material flow is formed in the screw groove. Under the action of temperature specified by the process, the plastic is changed into a plastic object in a molten state from a solid state, and then the completely plasticized plastic is pushed into a machine head by the pushing or stirring of a screw; the material flow reaching the machine head passes through the annular gap between the mold core and the mold sleeve, is extruded from the mold sleeve opening and is extruded around the conductor or the wire core to form a continuous and compact insulating layer or sheath layer, and then is cooled and solidified to prepare the cable product.
In the process of extruding the cable sheath, when the sheath just comes out of a machine head, the temperature of the plastic is very high, and the plastic has the weight and naturally sags before the sheath is cooled and attached, so that waste products or defective products are generated. The existing control method adopts cold water to spray and cool, and the following problems appear in the using process: 1. if the water temperature is not well controlled, the plastic is rapidly cooled, and the smoothness of the surface of the plastic is easily caused; 2. the cooling distance is not easy to master, insufficient cooling can be caused if the distance is too far away, and water can splash onto a high-temperature machine head if the distance is too close, so that the service life of the machine head is influenced; 3. a large amount of cold water is used and sometimes the water is spilled on the ground.
Disclosure of Invention
The utility model provides a cable sheath rapid cooling device solves the problem that current cooling mode leads to product quality poor.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a cable sheath rapid cooling device, includes mold core and the die sleeve on the cable extruder, and the mold core is installed in the die sleeve, its characterized in that: and a cooling device is arranged at the feed end of the mold core and is used for accelerating the air flow speed in the inner cavity of the mold core.
Further inject above-mentioned technical scheme, cooling device includes the connecting seat, the governing valve, the vacuum pump, the connecting seat can be connected with the feed end of mold core, the inner chamber of connecting seat is the internal thread chamber from feed end to discharge end in proper order, conical flow control chamber, the circumference distributes on the side of connecting seat has a plurality of inlet ports, inlet port and flow control chamber intercommunication, the head end conical surface and the flow control chamber wall shape of face of governing valve form annular clearance, the external screw thread portion on the governing valve pole portion is connected with the internal thread portion of connecting seat, it passes the hole to be equipped with the heart yearn in the governing valve, the end of bleeding of vacuum pump passes through. The advantages are that: simple structure, convenient adjustment, adjustable cooling speed and good universality.
Has the advantages that: the utility model discloses an accelerate the air flow speed in the mold core inner chamber, make crowded melting form plastics on around the sinle silk cool down rapidly, improved the adhesive force of plastics on the sinle silk, avoided the plastics that come out from the extruder because of the deformation problem that the dead weight caused, improved product quality.

Detailed Description
As shown in fig. 1, a cable sheath rapid cooling device comprises a mold core 1 and a mold sleeve 2 on a cable extruder, wherein the mold core is arranged in the mold sleeve, a cooling device is arranged at the feed end of the mold core, and the cooling device is used for accelerating the air flow speed in the inner cavity of the mold core;
as shown in fig. 1, cooling device includes connecting seat 3, governing valve 4, vacuum pump 5, the connecting seat passes through the welding or the screw thread mode is connected with the feed end of mold core, the inner chamber of connecting seat is interior screw thread chamber 301 from feed end to discharge end in proper order, conical flow control chamber 302, the circumference distributes on the side of connecting seat has two gas pockets 303, the inlet port communicates with the flow control chamber, the head end conical surface and the flow control chamber wall shape of face of diaphragm valve form annular clearance, the external screw thread portion on the governing valve pole portion is connected with the internal thread portion of connecting seat, it passes hole 401 to be equipped with the heart yearn in the governing valve, the end of bleeding of.
The working principle is as follows: as shown in fig. 1, when the regulating valve is rotated, the larger the annular gap between the conical surface of the head end of the regulating valve and the wall surface of the flow regulating cavity is, the faster the air flow speed is, and conversely, the smaller the air flow speed is; that is, the faster the air flow rate, the faster the cooling rate, and conversely, the cooling rate is slow. Because the sinle silk 6 that removes is clearance fit with the mold core inner chamber, the plastics 7 heat between mold core and mould cover can be taken away to the air that flows in the mold core intracavity, and the vacuum pump realizes the air rapid flow in the mold core intracavity, reaches rapid cooling's purpose promptly, guarantees that fashioned sheath 8 does not take place to deform on the sinle silk.
The details not described in the present specification are conventional in the art.
