The said transmission mechanism 4 of present embodiment comprises first drive 41, second drive 42, the first speed change turriform drive 43, the second speed change turriform drive 44, first gear 45, second gear 46 and the 3rd gear 47; First drive 41 is arranged on 2 of the drive motors, and second drive 46 is coaxial with the first speed change turriform drive 43, and the second speed change turriform drive 44 is coaxial with first gear 45; First gear 45 and second gear 46 are engaged transmission or chain transmission; Second gear 46 is coaxial with the 3rd gear 47, and drive motors 2 drives first drive, 41, the first drives 41 and drives second drive 42; Second drive 42 drives the first speed change turriform drive 43; The first speed change turriform drive 43 drives the second speed change turriform drive, 44, the second speed change turriform drives 44 and drives first gear, 45, the first gears, 45 drives, second gear 46; Second gear 46 drives the 3rd gear 47; Second gear, 46 coaxial drive feeding eccentric wheels 35, feeding eccentric wheel 35 drive pay-off 3 work, and the 3rd gear 47 drives cutter 5 work.Through adjusting chain or belt in the position of the first speed change turriform drive 43 and the second speed change turriform drive 44, adjust gearratio, thus the speed of control cutter and pay-off.
The said cutter 5 of present embodiment comprises upper cutter 51, lower cutter 52, upper cutter guide rail 53, upper cutter knife rest 54, upper cutter connecting rod crank 55 and eccentric wheel 56; Said upper cutter 51 is fixed on the upper cutter knife rest 54; Said upper cutter guide rail 53 is two, and upper cutter knife rest 54 2 ends are arranged in two upper cutter guide rails 53 and along two upper cutter guide rails 53 and slide, and said upper cutter connecting rod crank 55 is two with eccentric wheel 56 quantity; Said upper cutter connecting rod crank 55 is arranged on the eccentric wheel 56; Two eccentric wheels 56 are arranged on the same turning cylinder, and said transmission mechanism 4 drives eccentric wheel 56 through turning cylinder and rotates, and eccentric wheel 56 drives upper cutter knife rest 54 through upper cutter connecting rod crank 55 and in upper cutter guide rail 53, slides up and down; Lower cutter 52 is fixedly installed on the frame 1, and upper cutter 51 is corresponding with lower cutter 52 positions.
Also be provided with the timing gear wheels between said feeding ratchet 39 of present embodiment and the feed length change gear 310; Said timing gear wheels comprise a gear wheel 312 and a pinion 313; Gear wheel 312 is coaxial with feeding ratchet 39; Pinion 313 is coaxial with feed length change gear 310, and gear wheel 312 is engaged transmission or chain transmission with pinion 313, and present embodiment is the chain transmission.
Tape-cutting machine feeding process of the present invention is: transmission mechanism 4 drives feeding eccentric wheel 35 and rotates; Feeding eccentric wheel 35 drives semicircular gear 38 through feeding connecting rod 37 and swings back and forth; Semicircular gear 38 send the feeding action that stops through feeding ratchet 39; Feeding ratchet 39 reaches the action of transferring power and adjustment feed length through timing gear wheels and feed length change gear 310; Feed length change gear 310 drives first drawing-inroller 31 and second drawing-inroller 32 rotates, thereby finally realizes the purpose of feeding and adjustment feed length.
The tape-cutting machine process of cutting of the present invention is: transmission mechanism 4 drives eccentric wheel 56 through power transmission shaft and rotates; Eccentric wheel 56 drives upper cutter knife rest 54 through upper cutter connecting rod crank 55; Upper cutter knife rest 54 slides up and down at upper cutter guide rail 53, and when upper cutter 51 rose, pay-off 3 started feeding; When upper cutter 51 drops to minimum point, cooperate lower cutter 52 to realize cutting.
Because pay-off of the present invention comprises three drawing-inrollers, first drawing-inroller and second drawing-inroller are arranged on the frame, and the 3rd drawing-inroller forms with first drawing-inroller and second drawing-inroller through extension spring and cooperates; After strip passes the gap between first drawing-inroller and the 3rd drawing-inroller, pass the gap between second drawing-inroller and the 3rd drawing-inroller again, strip is pressed between first drawing-inroller and second drawing-inroller; And second between drawing-inroller and the 3rd drawing-inroller, compares prior art, under square one; The present invention program's drawing-inroller doubles to the driving force of strip; Strip is difficult for skidding, so the feed length uniformity obtains strong guarantee, and because the 3rd drawing-inroller is pulled to first drawing-inroller and second drawing-inroller by extension spring; So need not to adjust the gap between the drawing-inroller, convenient reliable again.
First drawing-inroller described in the present embodiment and second drawing-inroller also can be for one of them be the active drawing-inroller, and one is passive drawing-inroller, and the 3rd drawing-inroller is passive drawing-inroller, can reach same beneficial effect; Said elastic component also can be stage clip, presses to the 3rd drawing-inroller in the middle of first drawing-inroller and second drawing-inroller, also can reach same beneficial effect.
In addition; Because upper cutter is arranged on the upper cutter knife rest; Two ends of upper cutter knife rest are connected with the upper cutter connecting rod crank respectively, thus the driving force that the present invention program's upper cutter knife rest moves up and down be in admirable proportion, can secundly; So upper cutter can be done very widely, cuts width and also is increased dramatically.
In addition, owing between feeding ratchet and feed length change gear, also increased the timing gear wheels, said timing gear wheels are the speed increasing gear group, and the timing gear wheels make the scope of feed length obtain enlarging, and cutoff length can reach several meters.
In the present embodiment, said drive motors also can adopt buncher, and transmission mechanism comprises the 3rd gear; The 3rd gear and feeding eccentric wheel are arranged on the same turning cylinder; Buncher drives said turning cylinder indirectly or directly, and turning cylinder drives the 3rd gear and feeding eccentric wheel, the work of the 3rd gear driven cutter; The feeding eccentric wheel drives pay-off work, can reach same transmission effect.
In the present embodiment, on the said upper cutter heater and temperature controller can also be set, thereby can realize fervent function.
In the present embodiment, said tape-cutting machine can also comprise brake apparatus, and brake apparatus comprises auto-counter and material inductor; Can set and cut band quantity; Reach when setting quantity, brake apparatus can be controlled tape-cutting machine and quit work, when the material inductor detects material and uses up; Also can control tape-cutting machine and quit work, thereby can realize full-automatic operation by brake apparatus.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure that utilizes specification of the present invention and accompanying drawing content to be done, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
