Below in conjunction with accompanying drawing, introduce summary of the invention in detail.Structure of the present invention as shown in Figure 2.(1) is spraying one deck organic head roll among the figure, and spraying organic purpose is the friction force that increases between cylinder and the belt, with two synchronizer gears or utilize the fluid power shaft coupling to make two cylinders synchronous; (2) be flute profile turning cylinder, overcome the shortcoming that general arc turning resistance increases; (3) be the carrying band; (4) be pressure zone; (5) be the left and right spring-loaded idler that revolves; (6) be track adjusting wheel; (7) for tightening up stake, puts weight hammer type; (8) be vane type cleaning changed course cylinder certainly, can clear away the material on the adhesive tape automatically; Concrete structure as shown in Figure 6, (16) are the steel pipe crossbeam among the figure, (17) are steel plate circular cone tube, (18) are axle sleeve, (9) are carrying band aircraft tail cylinder; (10) be loading hopper; (15) be flute profile magnetic carrying roller.Specifically as shown in Figure 7.

This machine running state is good, has that noise is low, a not spreading, advantage such as sideslip not.On Fig. 1, when material when (10) are added in carrying band (3) and go up, material all concentrates in the band, when crossing the turning cylinder, pressure zone (4) becomes flute profile, carries with cover on material.Transport to when promoting section, two bands all become flute profile, owing to adopt the nylon core rubber tape, elastic deformation is big.But after two sidebands hold, produce the tensile stress to both sides, its power size is:

P＝2T/Bsinθ

T is the adhesive tape horizontal tensile stress in the formula; B is a bandwidth; θ is a groove angle, and it is with the different changes automatically of material.

This machine pressure zone limit can be iron powder rubber, and the carrying band edge is a magnetic, and two bands fit tightly, and flute profile carrying roller (15) is sintered into discoid by magnetic, and is outside with carrying carrying magnetic unanimity, owing to the same sex is repelled each other, thereby carrying band suspension operation.For preventing drift about adhesive tape contingency, also be provided with gear wheel.Spring-loaded idler is out of shape according to the material profile, remains certain back pressure.During turning cylinder (2), the carrying band is flute profile above material rises to, and pressure zone then covers material, cross the turning cylinder after, two bands separate gradually, material falls at carrying band (3) self-driven cylinder.Fig. 2 upper spring carrying roller is made up of a left-handed spring and spring of dextrorotation, fix with band spiral fluted short cylindrical in the centre for two, two ends then are enclosed within on separately the bearing box (11), stretching out the same universal-joint of a minor axis (12) in the bearing hole links to each other, the universal-joint other end is screw rod (12), in order to regulate initial tension, (12) are fixed on the channel-section steel frame (14).Install a pair ofly at a certain distance, its spacing is by calculating decision.Fig. 4 is the guiding pinch roller (6) that vertical section entrance and exit and interlude are installed, and it is fixed on the frame (14).Before two adhesive tapes are because of the suction adhesive, its guiding is aligned, prevent skew, be sealed in two interbands to guarantee material.

The magnetic holder belt vertical-lift machine model of making according to above-mentioned principle, the magnetic rubber band is a NdFeB magnetic powder, make by inventor's technology, because magnetic energy product and retentivity are all greater than common ferrite, so can be mixing with plastic, rubber, decide on the transported material kind wide about in the of 1/5 of adhesive tape overall width that accounts for of tape.Belt speed is optional from 1～3.15 meter per second, and freight volume is up to more than the kiloton, and 10～100 meters of height are optional, the thickest 3 layers of nylon rubber belt, and shown in Fig. 8-1, wherein (19) are the nylon core belts, and (20) are topped glue, and (21) are NdFeB magnetic powders; Among Fig. 8-2, (22) are NdFeB magnetic powders.The magnetic recording tape of two band edges can once vulcanize to be made, or pastes sticking making, and as can being stained with one deck magnetic sideband for old band, thereby the present invention's popularization is very easy.Spring-loaded idler adopts 60SiMn steel spring steel to make through heat treatment, and vertical direction is every 0.4 meter one group, and the guiding pinch roller is placed on the vertical section entrance and exit and respectively pacifies one group.Head roll spraying polyamine fat layer becomes little round bead shape, to increase friction force, has overcome the complex process and the wear-resisting not enough shortcoming of general casting rubber cylinder.The weight hammer type tightening devices of two bands can be with the payload automatic lifting, thereby has guaranteed that skidding does not take place again simultaneously unlikely being broken of adhesive tape.On the backhaul band of two bands swabbing pig is housed, with the cleaning residue.
