The specific embodiment
Do further to detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
Referring to Fig. 1, Fig. 2 and Fig. 3, the printer embodiment of the utility model roughly comprises: main body 1, upper cutter part 3 and lower cutter part 4.
Upper cutter part 3 comprises upper cutter 31 and driver element 32.Referring to Fig. 5; Driver element 32 is made up of motor 321, thumb wheel 322, worm screw 323 and cam mechanism 324; This thumb wheel 322 links into an integrated entity with worm screw 323; Can stir these thumb wheel 322 actions through manual work and drive worm screw 323, drive upper cutter 31 knee-actions mounted thereto thereby order about this cam mechanism 324.
Lower cutter part 4 comprises lower cutter 41, cutter paper unit 2, installing rack 44 and retraction mechanism.In the present embodiment, this installing rack 44 is shrouding assemblies.This retraction mechanism comprises:
Fixed head 42, in order to fixing this lower cutter 41, its lower end is provided with pivot 421 to be installed in pivotly on this installing rack 44, and the lower end of this installing rack 44 itself then is to be installed in pivotly on the main body 1;
The locking unit; With so that this installing rack 44 be in the lockup state that does not link to each other with this main body 1 pivotly or be in the open mode of the certain angle that can pivot forward; It comprises the slide plate 47 that is installed on this installing rack 44 and can receives external force effect action downwards, can make this slide plate 47 maintain/be returned to an elastomeric element 49 of top position and is installed in a block 11 that matches with this slide plate 47 on this main body 1 that this slide plate 47 is provided with a chute 474 and a bonding jumper 472; And
One actuation unit is installed on this installing rack 44 and is positioned at a side of this fixed head 42 and the combination of lower cutter 41, can receive the external force effect and divides two sections stroke ground to move downwards.Referring to Fig. 4 to Fig. 8, it is can act on this balancing unit so that the combination of this fixed head 42 and lower cutter 41 converts the withdrawing state into from normal condition at first section stroke.Referring to Fig. 9 to Figure 12, can act on this locking unit so that this installing rack 44 converts open mode into from lockup state at second section stroke.It comprises a location sensitive switch (scheming not shown) that is arranged on this first section stroke and second section stroke intersection; This location sensitive switch can be notified the processor in the printer; Let the motor 321 of this processor control upper cutter part 3 work, with the return of automatic realization upper cutter 31, usually; The time that this return realization process is spent is in 1S, and is rapid in the extreme.Actuation unit comprises a body 45 that can receive the external force effect and move downwards and can make this body maintain/be returned to an elastomeric element 48 of top position; This body 45 is provided with one handle 451, in order to one first mating part that cooperates this balancing unit and in order to cooperate one second mating part of this locking unit.This first mating part comprises a chute 452 and one first block 454 that is arranged on the vertical extension in these body 45 tops; The pivoting head 461 of cam 46 is replaced below first block 454, rotates so that cam 46 can move and drive camshaft 431 in this chute 452; This second mating part comprises one second block 453 that is arranged on these first block, 454 belows; This second block 453 can with bonding jumper 472 butts on the slide plate 47; And during second stroke, drive slide plate 47 to move downwards, no longer receive the restriction of block 11 until the upper end 471 of slide plate 47.
The printer of the utility model and the operation principle of retraction mechanism thereof roughly comprise:
When printer is in normal condition; Handle 451 is at the highest notch by the effect of extension spring 48; Slide plate 47 is at the highest notch by the effect of extension spring 49; Cam 46 is at the highest notch, and the cutting face of camshaft 431 and fixed head 42 contact angle a are 90 degree, and spring 432 applies power backward for fixed head 42 and lower cutter 41.
When the frictional force effect that runs into paper in the paper-cut process when the upper cutter 31 of printer can not be return; Just during paperboard; Motor 321 stops operating--and burn out for avoiding motor, can behind certain hour, cut off motor power by relevant detection switch notification processor motor is quit work.At this moment, the attendant can push handle 451 downwards, and handle 451 is walked the process of first stroke downwards; Can drive cam 46, cam 46 can drive camshaft 431 rotating certain angle, under the effect of spring 432; Fixed head 42 also can rotate a corresponding angle with lower cutter 41, finishes until first stroke, at this moment; Referring to Fig. 7 and Fig. 8, the cutting face of camshaft 431 and fixed head 42 contact angle a are 150 degree, upper cutter 31 and the certain at interval distance in lower cutter 41 meeting front and back; The location sensitive switch then can be resumed work by notification processor control motor 321, and motor 321 drives worm screw 323 and rotates, and worm screw 323 drives cam mechanism 324 actions and returns original position to drive upper cutter 31; Simultaneously, limited 21 at the rear of lower cutter 41 is blocked, and the upper end 471 of slide plate 47 receives block 11 restrictions to make lower cutter part 4 not open.Then, the attendant continues to push handle 451 downwards, and handle 451 is walked the process of second stroke downwards, and second block 453 cooperates with bonding jumper 472 butts on the slide plate 47; It is descending to drive slide plate 47, and simultaneously, camshaft 431 is rotated further-referring to Figure 10, but since limited 21 at the rear of lower cutter 41 block; Lower cutter 41 can not be rotated further itself, finishes until second stroke, at this moment; Block 11 can not block the upper end 471 of slide plate 47, and lower cutter part 4 just can outwards be opened, to carry out the maintenance work such as removing paper scrap; Finish until removing, make lower cutter part 4 get back to lockup state again, printer can be devoted oneself to work again.
Just in case; The location sensitive switch has been broken, and perhaps motor 321 is bad, and perhaps the drive circuit of motor 321 situation such as broken occurs; When causing above-mentioned first stroke to finish; Upper cutter 31 can not self-return, and then the attendant must rely on thumb wheel 322 manually after upper cutter 31 returns, could push handle 451 downwards and cover second stroke to implement corresponding maintenance work.
More than, be merely the preferred embodiment of the utility model, be intended to further specify the utility model, but not it is limited.All simple substitution of carrying out according to above-mentioned literal and the disclosed content of accompanying drawing are all at the row of the rights protection scope of this patent.
