The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 to Fig. 3, the auxilliary paper collecting table device of automatic die cutter of the present utility model comprises paper collecting table framework 1, auxilliary paper collecting table and synchronization chain transmission device, wherein,
Paper collecting table framework 1 is made of a pair of horizontal guide rail 11 and a pair of vertical guide rail 12, captives joint with the tail end of horizontal guide rail 11 by substrate 10 in the upper end of vertical guide rail 12;
Auxilliary paper collecting table 2 is made of belt 20 and the shifting bar 21 that is connected belt 20 front ends, and it can move along paper collecting table framework 1;
The synchronization chain transmission device can drive auxilliary paper collecting table 2 and move along paper collecting table framework 1, it comprises: a drive motor 30, a transmission shaft 31, a pair of drive sprocket 32, a pair of driven sprocket 33 and a pair of ring chain 34, wherein, drive motor 30 is a servomotor, one main gear 300 is installed on its output shaft, and it is installed in the outside, lower end of a vertical guide rail 12 of paper collecting table framework 1; Transmission shaft 31 is erected at the lower end of the vertical guide rail 12 of paper collecting table framework 1, and the one end is connected with the gear 300 of the output shaft of drive motor 30 by a switching mechanism 4; A pair of drive sprocket 32 is installed in the two ends of transmission shaft 31 respectively; A pair of driven sprocket 33 is installed in the head of the horizontal guide rail 11 of paper collecting table framework 1 respectively; A pair of ring chain 34 is looped around respectively on the driven sprocket 33 of 11 ones on the drive sprocket 32 at transmission shaft 31 two ends and horizontal guide rail head; The two ends of the shifting bar 21 on the auxilliary paper collecting table 2 are fixed on the ring chain 34, and this shifting bar 21 drives auxilliary paper collecting table belt 20 and moves with ring chain 34.
Switching mechanism 4 is a friction clutch, and it comprises that one is installed in that adapter sleeve 41, on the transmission shaft 31 is installed in pinion 42 on the adapter sleeve 41, two Friction disks 43 and that are installed in pinion 42 two ends respectively are installed on the transmission shaft 31 and is positioned at the nut 44 of adapter sleeve 41 outer ends.
The bottom of vertical guide rail 12 is also fixed one and is used to regulate the tension wheel 35 of ring chain 34 elasticities.
The principle of work of the auxilliary paper collecting table device of automatic die cutter of the present utility model is:
After 6 collections of main collection 5 are full, convert auxilliary paper collecting table 2 to and accept collection, adopt closed ring chain 34 transmissions owing to can drive auxilliary paper collecting table 2 along the synchronization chain transmission device that paper collecting table framework 1 moves.Drive sprocket 32 drives ring chain 34 and does circulatory motion, drives the shifting bar 21 that is fixed on the auxilliary paper collecting table 2 on the ring chain 34 and moves.Because the drive motor 30 that the synchronization chain transmission device adopts is programmable servomotor, improve auxilliary paper collecting table 2 serviceabilitys again, provide possibility for the running velocity that improves auxilliary paper collecting table 2 simultaneously.
Relatively drive with common electric machine, auxilliary paper collecting table belt 20 stretches out and regains more steadily, and need not to rely on the limit switch location, and auxilliary paper collecting table belt 20 each stop positions maintenances are accurate.Limit switch is that at both ends plays the security insurance effect.And auxilliary paper collecting table 2 can move under very high speed.
Between drive motor 30 and drive sprocket 32, friction clutch is installed again, overload protection is provided, guarantee the safe operation of synchronization chain transmission device.
Since improved the speed of auxilliary paper collecting table 2 operations, full when main paper collecting table 6 collections, need convert to when assisting paper collecting table 5 collections, machine generally need not reduce running velocity.Auxilliary paper collecting table belt 20 stretches out fast, converts auxilliary paper collecting table 2 collections automatically apace to.After auxilliary paper collecting table 2 collections are full, auxilliary paper collecting table belt 20 fast automatic returning, pile 5 is fallen on the main paper collecting table 6.Machine converts main paper collecting table 6 work again automatically to, has improved work efficiency.
Because machine is constant-speed operation all the time, guaranteed the conformability of machine cross cutting printing accuracy rate, under the situation of thermoprint operation, can guarantee that the thermoprint product design can not occur fluctuation because of the operation of auxilliary paper collecting table 2.On the other hand, owing to avoided the machine busy shift, also be favourable to the wearing and tearing that reduce machine.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
