In above-mentioned metal foil splitting device, cutting-in governor motion includes worm gear and the worm screw being arranged on knife rest plate, blade Frame is fixed on the output shaft of worm gear;Described worm screw, which rotates, causes worm gear synchronous axial system, causes blade holder to turn around knife rest axis It is dynamic, realize that cutting-in is adjusted.
In above-mentioned metal foil splitting device, the output shaft of worm gear is the knife rest axis of square cross section, with blade holder tail end The square groove of setting matches.
In above-mentioned metal foil splitting device, the front end of worm screw is provided with handwheel.
In above-mentioned metal foil splitting device, metal foil is aluminium foil or copper foil.
In above-mentioned metal foil splitting device, the depth of groove about 3-4mm on cutter groove roller, blade puts in the inside 1- of groove 15 2mm。
In above-mentioned metal foil splitting device, motor and one turn per minute of eccentric wheel.
Advantageous effects of the present utility model are as follows:
First, the utility model realizes the uninterrupted reciprocal fortune of blade in a lateral direction using eccentric wheel connecting rod mechanism Dynamic, the time in the absence of dead point or dead point in metal foil cutting is very short, effectively reduces the static cutting abrasion of blade, really Cut quality is protected.
2nd, the utility model uses worm and gear as the cutting-in governor motion of core component, realizes blade in longitudinal side The position adjustments and compression in upward namely depth of cut direction, the blade of blade is fixed on cutter groove roller and metal foil is closed On suitable position, and it is spacing using the auto-lock function progress of worm and gear, it is ensured that cutting precision and quality.
3rd, blade holder of the present utility model is fixed on the square shaft of worm-wheel shaft by the square groove on support body, works as hand wheel rotating, Screw rod is caused to rotate so that worm gear synchronous axial system, cause the blade holder that the square shaft on worm-wheel shaft is rotated and is stuck on square shaft to rotate, The regulation of the distance between blade and metal foil has been conveniently realized, and has been had the function that reliable and stable.
4th, the utility model replaces common metal blade using blade made of ceramics, has wear-resisting, high temperature resistant, enters One step improves blade life.

Embodiment
As Figure 1-3, constant speed rotates cutter groove roller 2 under power drive, drives metal foil 20 from blowing wheel 10 Unreel.Blade 3 is overlayed inside the groove 15 of cutter groove roller 2, and metal foil 20 cuts into two parts by blade 3, is wound respectively On one winding wheel 1 and the second winding wheel 21.
Blade 3 is installed in blade holder 4, and square groove 30 is provided with blade holder 4, the square groove 30 just with the side on worm gear 5 Shape knife rest axis 23 matches.Worm screw 22 is fixed on knife rest plate 7, and the front end of worm screw 22 is handwheel 29, rotates handwheel 29 so that The concomitant rotation of worm screw 22, cause the synchronous axial system of worm gear 5, the output shaft of worm gear 5 is the also concomitant rotation of knife rest axis 23, then blade holder 4 rotate around knife rest axis 23, cause the distance between blade 3 and metal foil 20 to change, and play a part of adjusting depth of cut.Figure The cross section of 2 intermediate slide axis 23 is square axle structure, and the square groove 30 set with the tail end of blade holder 4 matches, and is had reliable and stable Effect.
Fluted 15 are set in Fig. 3 on cutter groove roller 2, its depth about 3-4mm, blade enters inside groove 15 when generally cutting 1-2mm.Due to the self-locking action of worm and wormwheel, the position of blade 3 can be kept constant in cutting.
Cause the easy erosion and wear of blade, this practicality to solve the problems, such as that traditional slitter blade cutting point is fixed It is new to employ reciprocating device so that uninterruptedly being moved back and forth along blade direction in blade cutting.
Motor 9 rotates in Fig. 1, and the band synchronous axial system of movable eccentric wheel 8, front end and the knife rest plate 7 of guide rod 27 are solidified as a whole, guide rod 27 rear end is close on the edge of eccentric wheel 8, and eccentric wheel 8, which rotates, promotes guide rod 27 to overcome the pressure of spring 28 to move back and forth, and Blade holder 4, worm gear 5, worm screw 22 and handwheel 29 are arranged at knife rest plate 7, realize blade 3 along the uninterrupted reciprocal of blade direction Motion.Producing this continual move back and forth using this eccentric wheel push rod structure causes blade that dead point is not present in cutting Or the time at dead point is very short, the heating and abrasion of blade are substantially reduced, extends the life-span, it is ensured that the quality of product.
In specific implementation, 9 per minute 1 turns of motor, make the horizontal direction of blade 3 back and forth movement per minute.Blade is cut When aluminium foil or copper foil, edge makes edge not generate heat, keeps sharp state, the aluminium of cutting because moving back and forth one minute once Paper tinsel or copper foil knife-edge are smooth without burning without shirt rim, solve domestic aluminum foil material factory and battery capacitor enterprise production at present In the pressing issues for being difficult to overcome.
Further, blade is made of ceramics, and the life-span than common metal blade improves more than 50 times, further improves The quality of wearability and cutting products.
