Abstract
A continuously feeding plastic packer with magnetically levitated scalding blade, instead of mechanical heat seal, driven by step motors is composed of principal motor, delivering-feeding mechanism, cutter, and crank-connecting rod mechanism for bidirectional feeding. The primary drive chain driven by principal motor, main chain wheel, cooling blade driving roller, heat seal blade driving roller, longitudinal sealing rubber roller, film supporting rollers, and left and right step motors constitute a closed loop. Its magnetically levitated scalding blade installed to drive chain is driven by left and right step motors for making it synchronous with the object to be sealed.
Description
Technical field:
The present invention relates to plastic wrapping machinery technical field, exactly it is that a kind of no batch (-type) that the boiling hot cutter of magnetic suspension is housed walks to expect plastic packer.
Background technology:
Plastic bag making machine is a kind of machinery commonly used in the plastic wrapping machinery, present widely used plastic bag making machine to walk to expect that mechanism is mainly step, it drags brace and connecting rod framework by motor makes boiling hot cutter, cooling knife, cutting knife do reciprocating action, walk to expect mechanism's intermitten, material film heat and, cooling finishes when static, used the many places dancer to solve away the material buffer problem in the mechanism.Produce about sheet stock and be offset owing to intermittently walking material, and the sheet stock longitudinal stretching causes reject rate very high, directly influenced the cost of product.PE (height binder) Bag Making Machine, boundless heat-sealing machine, thermal cut Bag Making Machine or the like have been produced respectively in order to reduce the cost of product people, scald cutter with mechanical pressure heat and, its temperature booster is the pyrocondensation tubular type, the efficiency of heating surface is low, the heating and cooling time is long, and temperature control difficulty produces the reject rate height, and complicated in mechanical structure, maintenance difficult, the weight height, the ground area of standing is big, noise exceeds standard, workman's operating difficulties.China Patent No. 98234478 discloses the utility model patent that a kind of name is called " a kind of hot sealing device of plastic film bag making machine ", it remains in the hot knife the inside heat element is set, control heating by coupling apparatus by temperature controller, can not fundamentally address the above problem.China Patent No. 98100697 discloses the patent of invention that a kind of name by Japan Precise Machine Co., Ltd's application is called " the film tuck device in the packing device ", and it is a kind of simple plastic sheeting crimping unit, is not above-mentioned Bag Making Machine.China Patent No. 00221366 discloses the utility model patent that a kind of name is called " the compound cylinder bag of plastic knitting unit move flanging structure ", and it is different fully with the present invention.
