Description

Carton-punching roll pairs conveinent for adjusting pitch of holes

The utility model relates to a kind of light industry apparatus that can punch continuously on paper products or sheet plastic.It is specially adapted to the carton punching.

Having needs punching (for example fruit package paper case) on many wrapping cartons, so that ventilative.Drilling method commonly used at present is to use; the punching of following punch die straight line; hole count and pitch-row mostly are fixing greatly on its template; can only the die change plate if want to change arbitrary parameter; not only time-consuming but also require great effort; and this drilling method belongs to intermittently independently working, is difficult for and the online use of other processing equipments, must take manpower and production site separately; not only efficient is low; crudy is poor, also wastes energy, because mould is very stiff and demanding up and down; and be easy to dislocation; the waste material of adding cutting-out stops up tool bore and former often, and die wear is more serious, even mold damage and cause the saturating phenomenon of punching often; have to shut down and repair, so production cost is higher.Recently find to have the people to adopt the method (91217571.0 " plywood belt perforators of for example introducing on the patent documentation " and 91103536.2 " porous film manufacturing apparatus ") of roller type spreading punching, can carry out continuous drilling operation, and be easy to and the online composition production line of other processing equipments, improved production efficiency, a large amount of manpowers and unproductive time have been saved, but still need take production site separately, still fail to solve the adjustment of hole count and pitch-row, mould dislocation and the waste material that downcuts stop up chaste tree hand problems such as tool bore and former up and down.

Task of the present utility model provides a kind of carton punching roller pair, the advantage that not only keeps above-mentioned spreading punching to work continuously, also can make hole count, pitch-row and the aperture of getting be convenient to adjust and change, obviously improve the durability of cutter and it directly can be loaded on other carton processing equipments, drilling process and other manufacturing procedures are carried out synchronously, realize the carton one-shot forming, thereby not only increase substantially production efficiency, stop the repetition and waste of manpower, place and the energy, significantly reduce production costs, also will improve product processing quality.

This task can be finished in the following way, design a kind of carton punching roller pair of being convenient to adjust pitch-row, it is characterized in that, bottom roller is made up of two semicircle wheel hubs respectively, and it is fastening in addition with bolt, wherein be shaped on circumference T shape groove on the wheel rim of upper roller, one group of arc tool rest is fixed on the wheel rim by tommyhead bolt, be shaped on radially tool bore of stairstepping on the tool rest, be fixed with the perforating cutting tool of thin-walled cover shape in the hole, attach the chopping block pad (also being two semicircles) that one deck is made with the soft material of high tenacity on the wheel rim of bottom roller, the radius size of bottom roller should be basic identical with the cutter head radius of gyration on the upper roller.

Because upper and lower roller is formed by two semicircle wheel hubs, be convenient to dismounting and axially adjust mobile, be not subjected to the place axle to fasten stopping of other mechanisms, and can in fastening two semicircle wheel hubs, roller be fixed on the axle, the quantity of roller pair and position are determined according to the columns and the pitch-row in hole on the carton.Owing to be shaped on T shape groove on the upper roller wheel rim circumference, the tool rest that cutter is housed can be adjusted arbitrarily and move along the roller circumference, and the quantity of tool rest and circumferential position determine that according to the line number and the pitch-row in hole on the carton tool dimension is determined according to the carton aperture.Owing to cancelled former on the bottom roller, substitute by the soft chopping block pad of high tenacity that attaches, so needn't worry mould dislocation up and down and impact to cause that mould damages and the heavy wear problem, thereby obviously improved tool life, as for requiring bottom roller radius size and upper roller cutter head radius of gyration basically identical, be synchronous, prevent that cutter head from by the bottom roller tractive, influencing cutter life and crudy for the tangential velocity that makes cutter head and bottom roller wheel rim.This roller pair can be installed on any punching with diaxon up and down mechanically, carry out continuous drilling operation, more be suitable for to be installed on other carton associating processing equipments, in the operations such as cutting plate, fluting, corner cut and printing of carton board, the hole got, to realize the one-time formed hope of carton.Its production efficiency height, easy to adjust saving time saved manpower, place and electric power, the tool life height, product pitch-row, aperture and dimensionally stable reach specification requirement, and production cost obviously reduces, and is particularly suitable for using in the high efficiency production line in enormous quantities.

Cut paper waste material obstruction tool bore causes tool damage or the not saturating problem of punching in the prior art in order to solve, the utility model also can be made further improvement, for example can in tool bore, add ejecting mechanism, its structure can design like this, cutter is positioned on the center line of upper roller wheel rim T shape groove, the stage clip of packing in the cutter endoporus, the respective aperture of passing on this stage clip and the tool rest with a bolt puts in T-slot, put in part at it and carry on the back mutually tightly with two nuts, the head of bolt should be concordant substantially with the cutter outer end.Waste material may be oppressed stage clip by bolt head and entered in the tool bore during punching, but when waiting cutter to contact with the bottom roller disengagement, the tension of stage clip promptly ejects waste material by bolt head, and this has further improved the durability and the reliability of the present utility model of cutter again.

Accompanying drawing has provided an embodiment of the present utility model.

The concrete structure that has shown embodiment among the figure, its upper and lower roller (2) and (10) are formed by two semicircle wheel hubs, and it is fastening in addition by bolt (1) and (11), faying face to two semicircles during making should be repaired processing a little, fastening bolt when then installing (1) and (11) except that two semicircle wheel hubs can being combined, also simultaneously with whole roller with (A) and (B) hole be basal plane be fixed on the axle fasten.Wheel has keyway in the hole, and the one, in order to adapt to a last original key, do not influence installation, the 2nd, also can it carry out circumferential registration and transferring power in case of necessity.The available steel plate punching press of arc tool rest (5) is made, and be fixed on the wheel rim with tommyhead bolt (4), the ladder tool bore is arranged on the tool rest, be fixed with thin-walled cover shape cutter (7) in the hole, fixing method is varied, for example use screw threads for fastening, interference fit is fastening, and thin blade is curled into the cylindric hole that places and utilizes its tension fastening and radially fastening in addition etc. with the screw (3) of tool rest side.Attach the chopping block pad (12) that one deck is made with obdurability soft material (for example polyurethane plate) on the wheel rim of bottom roller (10), the attaching way is quite a few, for example uses sticker, and the usefulness counter-sunk screw is fastening, and also available clip is along wheel rim both sides clamping etc.As for said ejecting mechanism in the scheme, demonstration is also arranged among the figure, form by stage clip (8), bolt (9) and two back tightening nuts (6).
