Description
Technical field
The present invention relates to a kind of conveying belt carcass, in particular to a kind of Weaving type pierce tap conveys belt carcass.
Background technique
Conveyer belt, with widely, facilitates article to convey, greatly reduces labour, while mitigating labour in every profession and trade
Intensity, the belt carcass of conveyer belt is having five layers of belt carcass at present, and five layers of belt carcass need superposition in layer, in process of production, right
It is all bigger in energy consumption and artificial demand.
Summary of the invention
The technical problem to be solved by the present invention is to：For the various defects of the prior art and deficiency, a kind of braiding fashioned iron is provided
Silk ribbon conveys belt carcass.
The specific technical solution of the present invention is：A kind of Weaving type steel cord conveyor belt core, including packet pulp layer are set in packet pulp layer
There is braid over braid, braid over braid is radially steel wire, and steel wire is that high-carbon plates copper wire, and braid over braid broadwise is rigid line, and rigid line is that polyester fiber is hard
Line or glass fibre rigid line or nylon rigid line, braid over braid two sides are equipped with lock seaming line, and lock seaming line carries out the rigid line of kernmantle broadwise
Lock seaming.
A kind of preparation method of Weaving type steel cord conveyor belt core includes the following steps：
1. by steel wire by between one group of rubber roller, then by driven guide wheel and active guide wheel, driven guide wheel with
Active guide wheel is equipped with tensioner, so that it is generated identical tension every steel wire force by tensioner, keeps every steel wire
Power is consistent, i.e., is pre-stretched according to the intensity of steel wire, is allowed to keep every steel wire tension the same, generate the steel wire of identical tension by
Braider tethered sliding, steel wire balance movement under the action of rubber roller；
It is woven 2. steel wire keeps identical tension to enter braider, radial is steel wire, and broadwise is rigid line, according to required volume
Length and even density distribution are knitted, braider carries out two sides lock seaming in the weaving process, winding work is carried out after the completion of braiding
Or steel wire keeps identical tension to enter in next step；
3. the braid over braid that braiding is completed is moved in high-temperature shaping baking oven, steel wire keeps identical tension and braid over braid is opened up completely
It opens, high-temperature shaping oven temperature is set as between the degree of 180 degree -230, and baking time is less than or equal to 2 minutes, so that rigid line becomes
It is soft, since steel wire and rigid line are tension-like, so that the rigid line with steel wire infall forms arch bridge shape, realize that steel wire will not be in latitude
It is mobile to direction, guarantee that the positioning of steel wire fixes；
4. moving to braid over braid in cooling and shaping case from chain roller in high-temperature shaping baking oven after the completion of baking, make to weave
Band, which enters in dustfree environment, to cool down, and braid over braid cools down while moving, and when it removes cooling and shaping case, braid over braid is down to often
Temperature, so that rigid line fixes shape；
5. braid over braid is restored to, room temperature rear chain roller is mobile to be immersed in the slurry that can be bonded with steel wire, fiber and rubber
It in liquid, is fully bonded on braid over braid to slurries, braid over braid is removed from slurries, then moves into the drying box of 80 degree of -100 degree
Middle mobile drying, winds stand-by after drying.
This preparation method is flow line production, can complete finished product with one-pass molding, can also be segmented completion production, braiding
It is complete can rolling and storage, wait need to fix soaking paste when complete following process again.
Braided steel wire shape conveyer belt, which improves current wirerope shape band, does not have the technique of broadwise rigid line, reinforces the jail of conveyer belt
Solidity, while one-step shaping solves the complicated technology that wirerope shape band needs to increase under particular process environment broadwise rigid line,
It saves production cost and substantially reduces technique required time simultaneously.
This steel wire is high-carbon high-tensile steel wires, and steel wire strength is the three times or so of conventional bulk steel wire strength.
The present invention has following advantages due to the technical solution more than using：1. one layer of belt carcass of need can meet existing
Needed for five layers of belt carcass having, production technology and artificial is greatly saved in process of production, while reducing material requested, reduces life
Produce cost.2. reducing the thickness of conveyer belt, more application and environments can be applied, its application value is improved.3. thickness
Reducing reduces small product size, and same dosage substantially reduces its storehouse and deposits space, reduces transportation cost.4. thickness is bigger than existing belt carcass
It is big to reduce, the weight with body is alleviated, energy consumption when operation is reduced.
