Description
Technical field
The present invention relates to a kind of rubber product, especially a kind of airtight tubular conveying belt of fabric core.
Background technology
Tubular conveyor belt has following advantage because of it, more and more becomes the development tendency of mass transport industry:
Sealing is carried, and prevents that material is unrestrained, the Protection environment;
The crooked conveying satisfied the working space of more complexity;
Can complete high spud angle carries;
Can complete reciprocal transportation, save cost;
Can realize the conveying of high speed and large conveying quantity.
Tubular conveyor belt must become tubulose could prevent effectively that material from dispersing, trickling down when transported material.And tube-forming requires to carry with suitable lateral rigidity value, and can the size of rigidity be the key that form pipe.Rigidity is too large, and difficult one-tenth pipe even become to manage the friction force that also can increase between belt body and carrying roller, causes belt body to cross quick-wearing, increases simultaneously operating cost; Rigidity is too little, and the pipe that easily collapses can not be completed the transported material purpose.
The lateral rigidity value size of tubular conveyor belt limit section also determines the tube-forming energy, and load-transfer device is in service overlap joint (as Fig. 5), if the overlapping part rigidity is too large, large to carrying roller pressure, friction force is large, thereby affects the load-transfer device whole service life, increase simultaneously energy consumption, increase operating cost; If rigidity is too little, just easily produced the pipe (Fig. 7) that collapses, cause material from leakage, the design application purpose of out of reach tubular conveyor belt.
The load-transfer device industry has at the tubular conveyor belt of producing at present, comprises steel cord core tubular conveyor belt and fabric core tubular conveyor belt.But steel cord core tubular conveyor belt (as Chinese patent ZL 200820076084.7) cost is high, is suitable for simultaneously the material transportation of large conveying quantity and long haul distance; The heat-resisting degree of domestic existing fabric core tubular conveyor belt (as Chinese patent ZL 99224974.0) is low, and the pipe that easily collapses in use procedure causes the leakage of material, increases traffic cost.
Summary of the invention
The objective of the invention is to have into for overcoming above-mentioned common fabric core tubular conveyor belt that pipe is bad, easy the collapse technical deficiency of pipe now, the airtight tubular conveying belt of fabric core that a kind of cost is low, have good tube-forming and rigidity is provided.
For achieving the above object, the present invention adopts following technical proposals:
A kind of airtight tubular conveying belt of fabric core, described tubular conveyor belt longitudinally section comprises inside cover glue-line, some layers of framework material layer and outboard cover glue-line from inside to outside successively, wherein, between inside cover glue-line and framework material layer, between some layers of framework material layer, all be provided as the sticking adhesive layer of cambic horizon between framework material layer and outboard cover glue-line, be connected to form a cavity by the limit glue-line between inside cover glue-line both sides and outboard cover glue-line both sides, some layers of framework material layer by layer and sticking adhesive layer are set in cavity.
Described some layers of framework material layer comprise EP industrial canvas layer and the flexible industrial canvas layer of some layers that one deck and inside cover glue-line are close to.
The whole fabric width of described framework material layer is 95～98% of tubular conveyor belt belt body width;
Base portion in the middle of described every layer of flexible industrial canvas layer broad ways longitudinally line of centers is symmetrical arranged, and it is whole wide by 71～77% that described base portion accounts for flexible industrial canvas layer; Described base portion both sides outwards respectively are provided with two zones to flexible industrial canvas layer edge, and the canvas that flexible industrial canvas layer outermost two zone respectively account for flexible industrial canvas layer is whole wide by 2.0～3.5%; The canvas that respectively accounts for flexible industrial canvas layer with two zones of base portion next-door neighbour is whole wide by 9.5～11.0%.
The main points of tubular conveyor belt are to have good cross bending rigidity, especially carry band edge section characteristic to determine the tube-forming energy of load-transfer device.Rigidity is too large, is difficult to into pipe; Rigidity is too little, and pipe easily collapses.
1, belt body orlop framework material of the present invention is selected conventional EP industrial canvas.
2, other layer framework material selected by flexible industrial canvas, and material selection EP(warp is low contraction terylene industry long filament, and parallel is nylon industry long filament～polyamide fibre 66).
Polyester industrial filament yarn is low shrinkage industrial polyester filament.
Polyamide fibre 66 industrial filaments that the nylon industry long filament selects refreshing horse nylon chemical industry Co., Ltd to produce.
Lid glue and rubberizing are rubber.Lower cover glue has good anti-ozone, UV resistant, crack resistance, has simultaneously pulling strengrth and wear resisting property preferably; Upper cover glue directly contacts with material because of it, has improved its wear resisting property on the performance basis of lower cover glue; Rubberizing is the cambic horizon that covers between glue and framework material and framework material, mainly considers its dynamic adhesive ability.
Limit of the present invention glue width, lid glue thickness, the isoparametric selection of rubberizing thickness are all pressed the parameter of common fabric core tubular conveyor belt and are selected.Lid glue type of the present invention can be selected the types such as coventional type, oil-resisting type, wear-resisting type, heat resistant type, cold resisting type, low-rolling-resistance type.Girdle structure of the present invention can be two layers, three layers, four layers, five layers or six layers, and the belt body width can carry out different designs according to the material transportation condition simultaneously.
The technical characterstic of framework material of the present invention (industrial canvas) is:
The structure of industrial canvas:
The canvas both sides
APart, width respectively account for 2.0～3.5% of canvas overall width; In the middle of canvas
BPartial width respectively accounts for 9.5～11.0% of canvas overall width; Base portion in the middle of canvas
CWidth accounts for canvas whole wide by 71～77%.
The A district and
