Description
Technical Field
The utility model relates to a technical field of cable manufacture specifically is a preheating device who uses with extruder cooperation.
Background
The appearance of the multi-core sheath cable for the automobile is required to be uniform and round, the sheath is generally thin due to the thickness of the sheath, the conventional one-step forming extrusion sheath cannot cover strand marks formed by cabling and stranding of the multi-core cable, the surface of the cable is uneven, and the requirement of a client on the appearance of the cable cannot be met.
In order to meet the performance of the product, the sheath is produced by adopting a two-time layering extrusion process, and the phenomena of strand marks and unevenness on the surface of the cable can be effectively solved. The sheath is extruded in two times of layering, and the layering phenomenon is easy to occur, namely the sheaths extruded in two times are not easy to be bonded into a whole.
Disclosure of Invention
The utility model provides a preheating device matched with an extruder for use solves the problem that the sheath extruded twice is not adhesive.
In order to solve the technical problem, the technical scheme of the utility model is that: a preheating device used with an extruder comprises a bottom frame, and is characterized in that: the preheating device is characterized in that a preheating cylinder is arranged on the supporting surface of the bottom frame, the preheating cylinder can rotate around a cable through a rolling gear and a driving motor, an annular sliding contact line is arranged on the side surface of the preheating cylinder, the sliding contact line is connected with a heating part in the preheating cylinder, and the sliding contact line and the driving motor are connected with an electric cabinet in the bottom frame.
The technical scheme is further limited, and the preheating cylinder has the structure that: the heating device comprises a hollow barrel, wherein a heating barrel is arranged in the barrel, a heat insulation layer is arranged between the barrel and the heating barrel, gear rings are arranged at two ends of the barrel, the barrel is supported on rolling gears in a rolling mode through the gear rings, and a driving motor drives the gear rings to rotate through one of the rolling gears.
Has the advantages that: the rotary preheating device has the advantages of uniform heating, high heating speed and high universality, and solves the problem that the sheaths extruded twice are not bonded; the utility model discloses simple structure, convenient to use, improved the quality of product.

Detailed Description
As shown in fig. 1 and 2, a preheating device used in cooperation with an extruder comprises a bottom frame 1, a preheating cylinder 2 is arranged on a supporting surface of the bottom frame, the preheating cylinder can rotate around a cable through a rolling gear 3 and a driving motor 4, an annular sliding contact line 5 is arranged on the side surface of the preheating cylinder, the sliding contact line is connected with a heating part in the preheating cylinder, and the sliding contact line and the driving motor are connected with an electric cabinet 6 in the bottom frame.
The preheating cylinder has the structure that: the heating device comprises a hollow barrel body 201, wherein a heating barrel 202 is arranged in the barrel body, the heating barrel is a cylindrical ceramic heating body, a heat insulation layer 203 is arranged between the barrel body and the heating barrel, the heat insulation layer is formed by filling heat insulation cotton, gear rings 204 are arranged at two ends of the barrel body, the barrel body is supported on rolling gears 3 in a rolling mode through the gear rings, and a driving motor 4 is meshed with one of the rolling gears through a transmission gear; in order to avoid the axial displacement of the rotating cylinder, an axial limiting plate 7 can be arranged on the underframe.
Instructions for use: as shown in fig. 1, the preheating device is arranged in front of the extruder head, the control box controls the driving motor to drive the barrel to rotate, the electric power transmitted by the electric control box enters the heating element through the sliding contact line, and the heating element is a ceramic heating sheet; when carrying out the second layer sheath and extruding, let first layer sheath cable 8 pass in rotatory preheating section of thick bamboo, the piece that generates heat of circumference equipartition preheats in succession, and softening and little melting state can appear in first layer sheath surface, then extrude the second layer sheath in getting into the extruding machine aircraft nose, and the sheath of extruding twice can effectual bonding be in the same place, has solved the twice problem of extruding the layering of sheath.
The details not described in the present specification are conventional in the art.
