The ratio of whole L1/L2, and then adjust the magnification ratio of strengthening core protrusion, i.e., when L1/L2 is smaller, illustrate that magnification ratio is bigger, instead
It is then smaller.
In one embodiment, further include alarm module, alarm module is connect with detector.Wherein, alarm module can
Can also be the combination of buzzer or indicator light and buzzer to be indicator light.
When in use, strengthening core passes through detection device 3 out of detection pipe 31, and detector 321 is provided by force piece 324
Centripetal force is close to always with strengthening core, when on strengthening core have protrusion when, detector 321 pushes out, driving detection bar 322 around
Fulcrum 323 rotates, at this point, the other end of drive rod 322 is close to detection pipe 31, the position at the end is detected by sensing device 325
Distance is moved to illustrate that strengthening core product is unqualified when more than preset value, alarm by alarm module.In addition, reducing unwrapping wire
The unwrapping wire and take-up speed of device 4 and take-up 5 carry out the time of baking and curing to increase drying equipment 2 to glue, in turn
Ensure the bright and clean degree of reinforcement wicking surface.
This equipment is packed into actinobacillus device 4 in the strengthening core of the production present invention, by glass fibre, and glass fibre passes through coating
Device 1, glues fiberglass surfacing, is then heating and curing into drying unit 2 to surface glue, and then enters
Detection device 3 carries out finish detection to the glue after surface cure, when surface has protrusion, adjusts glass fibre movement speed
Degree increases glue in the drying time of drying unit 2, makes it when entering the second drying cavity 23, glue surface has been cured, no
It can be influenced by 23 hot wind of the second drying cavity, cause the damage on glue surface.
The advantageous effect that the present invention obtains：
(1) the glass fiber cable strengthening core prepared using above-mentioned preparation process and raw material proportioning has light weight, intensity
The advantages that height, stretch-proof.
(2) corollary equipment controls the speed of service by detection device, ensure that the quality of product, and makes glue coating more
Add uniformly.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
