Aluminium foil traction feed mechanism and hollow ventilation rubber roll thereof
Technical field
The utility model relates to a kind of trailer coupling of production facilities of extraction-type aluminium foil paper.
Background technology
Extract packing that aluminium foil paper is mainly used in the food and drink of large-scale hotel, aviation pantry food, refrigeration, fresh-keeping, heating etc.
The extraction-type aluminium foil paper generally adopts system controlled by computer high speed cutting off machine to produce.This machine keystone configuration is made up of frame, mechanical drive, discharge mechanism, traction feed mechanism, photoelectric detection mechanism, cutting mechanism, working plate and electric control box.The equipment of the type exists producing the aluminum foil thickness goods: during product between the 0.008mm-0.018mm, impression on finished product, occurs, to influence product appearance attractive in appearance; And the phenomenon of adhesion between product sheet and the sheet appears, influence product design.
Trace it to its cause, by the traction feed mechanism of equipment is caused.Equipment feed mechanism principle of work: form by a pair of rubber roll; And drive by dc speed-regulating motor; In the friction feeding process, the sheet stock that is stored in the floating compensation oscillating roller will constantly change the position of floating compensation oscillating roller, come the feedback compensation feeding speed through the displacement pickup that is installed in floating compensation oscillating roller location axle head; Make traction feeding rubber roll continual feed in a certain range of speed, to satisfy the requirement of stepping traction to feeding.When the aluminium foil material twisted in through this mechanism during production, the last lower rubber roller of trailer coupling passed through in order to make product smoothly, is provided with the groove of equidistance on the rubber roll surface, connected between the last lower rubber roller and by spring, drove the effect that material moves ahead to play friction.Material is when the gap through lower rubber roller on two, and passive being squeezed makes the groove trace of rubber roll and spring stay aluminium foil surface generation impression.If change no groove rubber roll, spring or reduce the production of rubber roll pressure; Particularity because of the aluminium foil material; When cutting off through rubber roll; Be prone to produce and be prone to produce sideslip when adhesion and material normally move or, can't guarantee product design and produce fluency because of tractive force less than two produces the stripping and slicing size differences with rubber roll.
Summary of the invention

Description of reference numerals: rigidity inner core 10; Intercommunicating pore 101; End plate 11,12; Via hole 121; Outer glue-line 20; Air extractor vent 201; Roll shaft 31,32; Keyway 311; Centre hole 321.
The specific embodiment
Focusing on of the utility model; To the drive roll of the trailer coupling of the production facilities (as: high speed cutting off machine) of extraction-type aluminium foil paper and driven voller wherein one transform; As, the driven voller structure is constant, can be steel rider, alloy roller or rubber roll; Drive roll then adopts following hollow ventilation rubber roll structure, and makes between drive roll and the driven voller to support with certain prestress elastic top and be connected.
As shown in Figure 1; Described hollow ventilation rubber roll; Has a rigidity inner core 10 (as: metallic materials such as steel cylinder or alloy material tube); Be coated with outer glue-line 20 (the about 3~15mm of these outer glue-line 20 single face thickness, the rubber hardness: Shao Shi 80-85 hardness of one deck polyurethane material or other elastomeric materials on these rigidity inner core 10 outer walls.
As shown in Figure 1; This rigidity inner core 10 is a hollow structure, and the two ends of rigidity inner core 10 are sealed with an end plate 11,12 respectively, and two end plate 11,12 outside sides respectively are connected with a roll shaft 31,32; 11 bonded assembly roll shafts 31 of one of them end plate are provided with keyway 311; Be used for carrying out power with traction power mechanisms such as motors and be connected, another end plate 12 is provided with the via hole 121 of perforation, with the centre hole 321 that then offers perforation on these another end plate 12 bonded assembly roll shafts 32; The inside of this rigidity inner core 10 is connected with compressed air source (like air pump, storage tank etc., all not giving diagram) through this via hole 121 and this centre hole 321.
As shown in Figure 1; Outside this, also be provided with on the glue-line 20 a plurality of perpendicular to outside the air extractor vent 201 on glue-line 20 surface; Be provided with intercommunicating pore 101 corresponding to 201 of each air extractor vents on this rigidity inner core 10, this intercommunicating pore 101 makes this air extractor vent 201 be connected with the inside of this rigidity inner core 10.
In addition; The outer end of this centre hole 321 also is connected with compressed air source; Make pressurized air get into these rigidity inner core 10 inside from this centre hole 321 and this via hole 121, the intercommunicating pore 101 through this rigidity inner core 10 and the air extractor vent 201 on should outer glue-line 20 blow to the outside of this outer glue-line 20 then.
Thus, in the time of between materials such as aluminium foil are through drive roll and driven voller, because this hollow ventilation rubber roll surface has air-flow to produce; Can produce supporting role to aluminium foil, its pressure that receives is reduced, thereby the surface can not produce the impression that stays because of extruding; And after between materials such as aluminium foil are through drive roll and driven voller; The air-flow on this hollow ventilation rubber roll surface can produce centrifugation to aluminium foil, avoids producing adhesion, therefore; The utility model has solved above-mentioned prior art not enough situation aborning, has ensured the fluency and the product design of producing.
More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from claim and limited and scope; Can make many modifications, variation or equivalence; As drive roll is not changed, driven voller is arranged to hollow ventilation rubber roll, also will fall within the protection domain of the utility model.
