Abstract
The utility model relates to an automatic feeder for a punch, in particular to a high-precision double-roller automatic rectification feeder. Main and auxiliary rollers and corresponding idlers are arranged on a feeding roller and a pressing roller, making the transmission speed more consistent and the component parts more compact; meanwhile a swing arm regulating mechanism is arranged at the upper part of the pressing roller, so that an auxiliary pressing roller can be flexibly raised during work to better coordinate the meshing between the idlers and the gears, thus solving the problem that linear velocity of the pressing roller is not the same with that of the feeding roller when the pressing roller is raised by material with certain thickness between the pressing roller and the feeding roller, which causes the problems of skidding and inaccurate feeding; therefore the automatic feeder makes feeding more accurate and improves punching quality.

Described nip rolls mechanism top is provided with the swing arm adjusting device, the upper end of its swing arm adjusting device is connected with secondary nip rolls, and this swing arm adjusting device is provided with rotating shaft at the idle pulley shaft core position of nip rolls mechanism, can be to lift secondary nip rolls in the rotation of basic point low-angle with this axle center.
Idle pulley in the described feeding roller mechanism is meshed with the idle pulley in the nip rolls mechanism.
The working surface of described secondary nip rolls is provided with one deck gelatinous layer.
The two roller automatic straightening feeders of a kind of high accuracy described in the utility model, it is provided with the master in feeding roller mechanism and nip rolls mechanism respectively, secondary roller and corresponding idle pulley, make that the speed of transmission is consistent more, outside each parts compactness, also the swing arm governor motion is set on nip rolls mechanism top, better coordinate the mesh degree between each idle pulley and the gear, when having solved between nip rolls and the feeding roller by certain thickness material, making to lift on the nip rolls causes the linear velocity of nip rolls and feeding roller inconsistent, cause the inaccurate problem of feeding of skidding, make feeding more accurately consistent, improved the quality of material binder.
Description of drawings:
Fig. 1 is an overall schematic of the present utility model;
Fig. 2 is the utility model cross-sectional view;
Fig. 3 is the utility model binder principle schematic.
The specific embodiment:
The utility model provides a kind of high accuracy two roller automatic straightening feeders, as shown in Figure 1, 2, the utility model comprises frame 100, feeds material assembly 200, transmission mechanism 300, binder pressure regulating mechanism 400, feeding roller mechanism 500 and nip rolls mechanism 600, nip rolls mechanism 600 is pressed on the top of feeding roller mechanism 500, feeding material assembly 200 is made up of feeding mechanism 210 and discharging mechanism 220, they lay respectively at the both sides of frame 100, and binder pressure regulating mechanism 400 is positioned at the top of frame 100 and is connected with nip rolls mechanism 600.In traditional feeder duty, between nip rolls and the feeding roller during by certain thickness material, because forcing on the nip rolls low-angle, lifts the thickness of material self, the gear that make to transmit can not compact being meshing with each other, cause the linear velocity of feeding roller and nip rolls inconsistent, cause that material skids and cause feeding inaccurate.And feeding roller described in the utility model mechanism 500 forms by main feeding roller 510, secondary feeding roller 520 and with an idle pulley 530 of main feeding roller engagement, and be respectively equipped with shaft transmission gear 511,521 on the major and minor feeding roller 510,520, this two travelling gear 511,521 all is meshed with the location idle pulley 540 that the bottom is provided with, and individual gears engaged degree is asynchronous can not to cause the inconsistent of feeding roller mechanism 500 linear velocities yet even have in the middle of like the mesh degree of so mutual compactness; Nip rolls mechanism 600 forms by main nip rolls 610, secondary nip rolls 620 and with another idle pulley 630 of main nip rolls 610 engagements, and the same shaft transmission gear 611 on the main nip rolls 610 is meshed with travelling gear 511 on the main feeding roller 510.The travelling gear 511 that constitutes so again on the main feeding roller 510 is meshed with travelling gear 611 on idle pulley 530 and the main nip rolls 610 respectively, and idle pulley 530 also is meshed with the idle pulley 630 on top, be synchronized with the movement down being meshing with each other of a plurality of gears like this, can control the whole synchronous operation of feeding roller mechanism 500 and nip rolls mechanism 600 accurately, reach good control feeding speed, the effect of accurate feeding.
In addition, described nip rolls mechanism 600 tops are provided with swing arm adjusting device 700, the upper end of its swing arm adjusting device 700 is connected with secondary nip rolls 620, and this swing arm adjusting device 700 is provided with rotating shaft 710 at idle pulley 630 shaft core positions of nip rolls mechanism 600, can be to lift secondary nip rolls 620 in the rotation of basic point low-angle with this axle center.As shown in Figure 3, swing arm adjusting device 700 turns over 0.96 °, and secondary nip rolls 620 is just upwards lifted on a little, then can send thickness and be 1.66 millimeters material, the extrusion stress excess load that has produced owing to uneven thickness when the having avoided feeding travelling gear that weares and teares.
During duty, the servomotor 310 of transmission mechanism 300 is controlled by electric cabinet, according to the pulse signal of setting, rotate a fixing angle at every turn, rotate synchronously thereby drive each gear by rotating with 320 travelling gears 511 that drive main feeding roller 510 synchronously.Idle pulley 530 in the described feeding roller mechanism 500 is meshed with the idle pulley 630 in the nip rolls mechanism 600, makes the feeding speed of main feeding roller 510 consistent with main nip rolls 610 speed.
