Description
Technical field
The invention belongs to material adhesive tape conveying machine accessory technical field, more specifically, relate to one
Wire belt trouble-saving alarm device.
Background technology
In material adhesive tape conveying machine field, the Belt transport battle line of sealing-tape machine is long, feed arduous task.Every year
Adhesive tape consumption is huge, brings huge cost pressure to enterprise.And the wire belt in adhesive tape is because of its price
Costliness, the ratio of consumption is about 55%.Wire belt in addition to normal attrition, some improper damages
Consumption (taking out steel wire, torn edges damage etc.) also occupies the biggest ratio, and these additional waste are the most millions of every year
Unit.Therefore, how to reduce or prevent the loss of these improper pierce taps to become material adhesive tape conveying machine field
The serious problems faced.Sealing-tape machine adhesive tape of the prior art is lost huge reason mainly to be had: 1) due to thing
The abrasion of material, impact, pad thick stick etc., the Steel cord of wire belt can be made to expose, without discovery in time,
The Steel cord exposed is possible to cause steel wire to be drawn out of, and causes wire belt entirety to damage, or causes
Accident occurs；2) wire belt is time in running, sideslip is serious, can make tape edge friction, cause glue
Belt edge steel wire fracture, finds finally adhesive tape torn edges accident not in time；3) some wire belts connect
Head, due to long-play, easily causes surface glue and comes off the phenomenons such as tilting, as found not in time, joint
Steel wire easily rots to damage, and ultimately causes adhesive tape and breaks accident.Wire belt once takes out steel wire, torn edges
Or the accident such as break, on the one hand bring to production and have a strong impact on, on the one hand bring immense pressure to cost.
Summary of the invention
The technical problem to be solved is: for the deficiencies in the prior art, it is provided that Yi Zhongjie
Structure is simple, the belt carcass at wire belt exposes, wire belt sideslip time damage of edges or joint aging and occur
After exposing plush copper, it is possible to wire belt surface abnormalities effectively detected and send alarm signal, in order to operator
Member shuts down in time and removes a hidden danger, thus the effect wire belt trouble-saving alarm device that prevention has an accident.
Techniques discussed above problem to be solved, the technical scheme that the present invention takes is:
The present invention is a kind of wire belt trouble-saving alarm device, and wire belt is arranged on material transportation rubber belt
On machine, wire belt trouble-saving alarm device includes appliance stand, movable installation baffle plate on appliance stand,
