Description

A kind of optical cable is produced with contactless on-line heating device with composite steel-plastic belt

Technical field

This utility model is related to a kind of heater, specifically, is related to a kind of production of optical cable composite steel-plastic belt with non- Contact on-line heating device, belongs to composite steel-plastic belt complex technique field.

Background technology

In traditional composite steel-plastic belt production technology, steel band is heated frequently with fluorescent tube.This mode of heating is Open heating, heat scatters and disappears greatly, and energy conversion rate only has 30 ~ 40%, and energy waste is serious.Dispersed heat makes space temperature 3 ~ 5 DEG C are raised, deteriorates production environment.Because traditional heating effect it is poor, it is temperature required in order to reach technique, frequently with increase heating On the one hand number of times and the mode for extending heat time heating time, this scheme causes production line very long, increased equipment and workshop building is thrown Money；On the other hand, extending heat time heating time causes speed of production slower, and the movement velocity of steel band most can only achieve soon 55 m/min, Production efficiency is relatively low.Furthermore, traditional heating mode has that difficult control of temperature and heating are uneven, is easily caused steel modeling The peel strength of composite band is not up to standard.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of efficiency of heating surface height, the optical cable of homogeneous heating and is moulded with steel Composite band is produced with contactless on-line heating device.

To solve above-mentioned technical problem, the technical solution adopted in the utility model is：

A kind of optical cable composite steel-plastic belt contactless on-line heating device of production, including shell, some heater wires Circle and heat-insulation layer, some heating coils surround the coil windings in flat hollow structure, and the heat-insulation layer is arranged Outside coil windings, the heat-insulation layer and coil windings are arranged inside the shell, and the internal cavities of the coil windings are steel modeling The passage of composite band.

Temperature measurement on-line sensor is additionally provided with the exit of the passage of composite steel-plastic belt.

This utility model compared with existing mode of heating, with following obvious advantage：1. the thermal efficiency is high, due to being directly right Steel band is heated, steel band self-heating, and the process without conduction of heat also reduces the loss of heat.2. firing rate is fast, , by carrying out " vortex " that " cutting " alternating magnetic field is produced during coil windings, heat response is fast, reduces heat time heating time, less for steel band Needs are preheated；3. heats are good, are mainly reflected in temperature uniformly, and in process of production temperature change is little, this is because " sending out Hot body " is steel band itself, and coil winding arrangement is fixed, and stability is high, non-aging failure, and the variant position of steel band is heated one Cause.

Description of the drawings

This utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the top view of Fig. 1.

Wherein, 1. coil windings, 2. heat-insulation layer, 3. shell, the 4. passage of composite steel-plastic belt, 5. temperature measurement on-line sensor, 6. heating coil.

Specific embodiment：

As depicted in figs. 1 and 2, a kind of optical cable composite steel-plastic belt contactless on-line heating device of production, including it is outer Shell 3, some heating coils 6 and heat-insulation layer 2, some heating coils 6 surround the coil windings in flat hollow structure 1, heat-insulation layer 2 is arranged on outside coil windings 1, and heat-insulation layer 2 and coil windings 1 are arranged in shell 3, the inside of coil windings 1 Cavity is the passage 4 of composite steel-plastic belt, and in the exit of the passage 4 of composite steel-plastic belt temperature measurement on-line sensor 5 is additionally provided with.

With in composite steel-plastic belt production process, at the uniform velocity through the passage of composite steel-plastic belt, rectification circuit is by 50/ for steel band for optical cable The alternating voltage of 60Hz becomes DC voltage, then DC voltage is converted into the high frequency that frequency is 20 ~ 40KHz through control circuit Voltage, at a high speed the electric current of change passes through heating coil can produce the magnetic field of change at a high speed, when steel band is through the magnetic line of force in magnetic field When, equivalent to steel band " cutting " magnetic line of force, countless little vortex are produced, make steel band itself voluntarily generate heat at a high speed, reach heating Purpose.This kind of mode of heating temperature-responsive is fast, and heat insulation effect is good, and energy conservation and consumption reduction effects are notable, while heating belongs to internal heat type, Heat energy loss is reduced, heat utilization rate is high, can improve the competitiveness of product.

Because electromagnetic induction heating effect is good, steel band is heated evenly, and the peel strength of composite steel-plastic belt is carried by 4.6 N/cm Up to 6.2 N/cm, product quality is improved, and defective products rate is reduced.
