Technical Field
The utility model relates to a rubber-insulated-wire cable manufacturing installation specifically is steel wire hot melt adhesive coating device is strengthened to rubber-insulated-wire cable.
Background
Rubber-insulated fiber cables, also known as butterfly cables and 8-shaped cables, are widely used in access networks because of their characteristics of softness, lightness and the like. On the cross section of the rubber-insulated optical cable, the optical fiber is positioned at the center, two steel wires or FRP (fiber reinforced plastics) non-metal reinforcements (used for enhancing tensile strength) which are arranged in parallel are arranged at two sides of the optical fiber, and finally, the sheath is extruded outside. In the rubber-insulated-wire cable production process, the hot melt adhesive needs to be scribbled on the steel wire in advance when the unwrapping wire to the power of being stained with of enhancement line with prevent that the steel wire from rustting. The existing steel wire gluing and gluing equipment (such as CN 112415688) is relatively complex in structure and relatively high in manufacturing cost; there is a need for further improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a hot melt adhesive coating device which can quickly and automatically coat the hot melt adhesive on a steel wire in the production process; and the structure is simple, and the manufacturing cost is low.
The utility model adopts the technical proposal that: a rubber-insulated optical cable reinforced steel wire hot melt adhesive coating device comprises a support vertically fixed on the ground and a control box which is arranged on the support and is provided with an electromagnetic controller; the method is characterized in that: the device also comprises a hot melt adhesive hopper which is arranged on the support and is made of a steel plate, a mould which is arranged below the hot melt adhesive hopper, a steel wire passing hole which is horizontally arranged in the mould and is communicated with the hot melt adhesive hopper, a heating coil which is wound outside the hot melt adhesive hopper and is communicated with the electromagnetic controller, and a heat preservation layer which is coated outside the heating coil.
And a glass fiber layer for insulation is arranged between the hot melt adhesive hopper and the heating coil.
The outside of the mould is also coated with a glass fiber layer, a heating coil and a heat-insulating layer from inside to outside in sequence.

Detailed Description
The invention will be further described with reference to the following examples shown in the drawings.
The rubber-insulated-wire cable reinforcing steel wire hot melt adhesive coating device shown in fig. 1 comprises a support 1 vertically fixed on the ground and a control box 2 installed on the support; a power switch communicated with an external power supply and an electromagnetic controller connected with the power switch are arranged in the control box; the electromagnetic controller is used for rectifying, filtering and inverting the power frequency alternating current into high-frequency current (16-30 KHZ), and the hopper wound by the electromagnetic coil is used for heating.
The utility model provides an among the device, the top of support still sets up a hot melt adhesive hopper 8 of steel sheet preparation, hot melt adhesive hopper below installation (usually through the bolt fastening to make things convenient for the change of mould) a mould 3, seted up in the mould level arrange and around link up cross steel wire hole 4, the aperture ratio steel wire diameter of crossing the steel wire hole is slightly big (0.3-0.5 mm big usually), should cross the steel wire hole still with the inner chamber intercommunication of hot melt adhesive hopper in addition, so that molten state's hot melt adhesive can pour into in the steel wire hole. The thickness of the hot melt adhesive is controlled by the inner diameter of the steel wire hole, so that the thickness uniformity of the hot melt adhesive on the surface of the steel wire can be ensured, and the waste caused by excessive gluing can be reduced. A heating coil 6 is wound around the outside of the hot melt adhesive hopper (the heating coil is connected to the electromagnetic controller through a wire) and is used for heating the hot melt adhesive in the hot melt adhesive hopper. In order to ensure insulation, a glass fiber layer 7 (formed by winding a glass fiber belt) for insulation is arranged between the hot melt adhesive hopper and the heating coil. The heating coil is externally coated with a heat-insulating layer 5 (preferably heat-insulating cotton).
Furthermore, the outside of the die is also coated with a glass fiber layer, a heating coil and a heat insulation layer (the orifices of the wire passing holes at the left end and the right end of the die are required to be exposed so as to be beneficial to the passing in and out of steel wires). The insulating layer is also preferably insulating cotton.
The utility model discloses a theory of operation is: the heating coil is connected with high-frequency current emitted by an electromagnetic controller, the hot melt adhesive hopper generates countless small eddy currents immediately to enable the hot melt adhesive hopper to heat itself, and the hot melt adhesive in the hot melt adhesive hopper flows into the steel wire hole after being heated to a molten state; on the other hand, the steel wire 9 released from the steel wire coil passes through the steel wire hole from right to left, and after the periphery is fully coated with hot melt adhesive, the steel wire enters (the direction is shown as an arrow A in figure 2) a sheathing die of a machine head of an injection molding machine, is arranged together with the optical fiber and is sheathed by sheathing material; and finally, guiding out the sheath mold, cooling and shaping to obtain the rubber-insulated-wire cable.
The above is the detailed introduction of the hot melt adhesive coating device provided by the utility model; for general manufacturers in the field, according to the ideas and principles of the embodiments of the present invention, there are changes in the specific implementation and application range; accordingly, the contents of this specification should not be construed as limiting the invention.
