Description
Technical field
The present invention relates to aramid fiber conveying belt joint technique field, specially a kind of high-intensitive aramid fiber conveying belt joint process.
Background technique
In recent years, the fast development of national economy be catalyzed the manufacturing industry scale such as steel, cement it is continuous expand, production capacity
It is continuously improved, these are all that material conveyer belt industry brings bigger opportunities and challenges, and client wants belt intension specification
Continuous improvement is asked, but common plain weave canvas improves intensity by the way of lamination, with body in the process through roller of overdriving
In, the difference of each layer skeleton radius of curvature causes the difference of stress, and strength specification improves, and the number of plies is more, and dynamic flexing performance is got over
Difference, band body is also heavier, and with the development of present technology, user replaces plain weave canvas with aramid fiber, however traditional aramid fiber is defeated
The shear strength for sending the intensity of belt lacing to fully rely on sizing material bulk strength and adhesive interface absolutely not utilizes aramid fiber canvas bone
The advantage of frame material high-strength and high-modulus, however traditional aramid fiber conveying belt strength of joint is low, and it is disconnected that connector easily occurs when conveying material
It splits, causes casualties.
Summary of the invention

F, it cuts finger: the dash area of two heads being cut away with specific purpose tool, carries out cutting finger by Figures 5 and 6；
G, fixation: putting vulcanizer in order, spread isolated material on hot plate, is fixed conveyer belt with fixture；
H, it cleans: the burr trimming on finger being cleaned out, buffings, dust are wiped, then are cleaned up with 120# gasoline；
I, brush coating is starched: rubber cement brushing 3 times；
J, lower caldding layer is spread；
K, row refers to: brush coating is starched in lower caldding layer core rubber, is arranged and is referred in order after dry；
L, coating is spread；
M, it prepares in advance: putting isolated material, suitable baffle, molding, fixing bolt, preparation sulphur on the made-up belt of forming
Change；
N, cold pressing sizing: being first put into cold press molding band embryo and carry out cold pressing sizing, time 20-30min；
O, heat cure: then the band embryo after cold pressing sizing is put into vulcameter and carries out vulcanizing treatment；
P, depanning: user is taken out the band embryo that vulcanization is completed using fixture.
Preferably, conveyer belt is put finger-type above according to center line to good when being fixed in the G step, and refer to root with
Finger tip pulls open half span from carrying out by Fig. 7 to finger.
Preferably, one layer of high-tenacity sticking adhesive layer is respectively covered in conveyer belt top and bottom when fixing in the G step, in high-tenacity
Dedicated kiss-coating framework material is placed on sticking adhesive layer as enhancement layer, pastes upper and lower covering glue layer again on enhancement layer.
Preferably, first pass is brushed second time after parching when brush coating is starched in the I step, and with a thickness of 0.2mm, second time dry
Brushing third time after thoroughly, with a thickness of 0.3mm, third refers to all over the rear preparation row of rubber cement dry 80% or so.
Preferably, curing temperature is 135-165 °C, vulcanization time 25-45min when heat cure in the O step, vulcanization
Pressure is 7-12MPa.
Compared with prior art, beneficial effects of the present invention are as follows:
1, the present invention by setting-out, fixed length, take off glue, polishing, picture refer to, cut finger, fixation, cleaning, brush coating slurry, paving lower caldding layer, arrange
The operation for referring to, spreading coating, prepare in advance, being cold-pressed sizing, heat cure and depanning step, it is high using aramid fiber canvas framework material
The advantage of strong Gao Mo, enhances the intensity of aramid fiber conveying belt connector, solves the problems, such as that traditional aramid fiber conveying belt strength of joint is low, prevents
Connector is broken when only conveying material, is avoided casualties, is worth of widely use.
