Description

A kind of office is with quick steel seal marking press

The utility model relates to a kind of office quick imprinter.

Traditional office is used hand lever formula structure mostly with the steel seal marking press, its shortcoming is that pressure is little, impression is light, and manual operation, labour intensity is big, efficient is low, more apparent heavy in file process in enormous quantities, in order to address these problems, existing electronic now steel seal marking press comes out, and its principle is utilized optoelectronic switch control circuit control motor to drive eccentric wheel by deceleration device exactly and rotated, and eccentric wheel promotes to be located at the slide block moving linearly in the frame upper hopper chute, cooperate the spring in the chute to make slide block finish linear reciprocating motion, thus by the last die that is connected with slide block be contained in frame at the bottom of on following die contact and finish moulding process.On its eccentric wheel, be provided with manual rocking handle, when power driven system breaks down, can realize manual impression.This automatic impression marking press that on the basis of traditional hand lever marking press, increases electric device, though it is big to have overcome manual operation labour intensity, inefficient problem, but it is little not solve its pressure, impression is light, cause the unsharp shortcoming of impression, and the fault rate height, service life is short.

The purpose of this utility model provides that a kind of pressure is big, and impression is clear, and the long office of efficient height and life-span is with quick steel seal marking press.

In order to achieve the above object; the utility model adopts following structure: comprise frame; motor; transmission mechanism; man-operated mechanism; on; the quick steel seal marking press of following printing mould structure and photoelectric control circuit; be characterized in: transmission mechanism adopts the eccentric bushing structure; the flange end of eccentric bushing is installed in the rolling bearing of upper rack; the flange end endoporus that eccentric main axis passes eccentric bushing is fixedlyed connected with the output shaft of decelerator; the motor of mechanical connection decelerator input is controlled automatically by the photoswitch circuit that has overload automatic reverse holding circuit; the crank end of eccentric bushing is connected with the upper holder block hinge; upper holder block is by the corresponding connection with lower lock block of spring; on; the corresponding flat end of lower lock block is the spill plane; last lower lock block all is placed in vertical chute on the frame; being fixed on baffle plate on the frame chute, will to go up lower lock block spacing in chute; lower lock block is connected with last die by regulating bolt; the holder of vertical installation steel seal also is provided with the secondary reinforcement and manually impresses mechanism on the last die on lower lock block.Be installed under the sphere on the support and cooperate the holder of mounting spherical seal in the die, the plane is gone up in the seal holder and steel seal holder plane adapts.

It is that hinge connects a depression bar on lower lock block that described reinforcement manually impresses mechanism, the one end hinge joint of the other end of depression bar and push rod is on the mandrel of frame, the other end of push rod links manual depression bar, manually the hinge joint of the other end of depression bar is equipped with the handle square groove on the external part of last item on the last item on the frame.

Described overload automatic reverse holding circuit by transformer B2, full-bridge, electricity through device RW, diode D6, triode V3, resistance R 10, R11, form amplifying circuit; the signal of telecommunication that amplifies enters the shaping on-off circuit of being made up of single-chip microcomputer IC2, diode D7 after diode V3 output, the negative-phase relay J2 that tends to act in the photoswitch circuit by diode D8, triode V4 moves.

Operation principle of the present utility model and feature are as follows, when use impresses function automatically, connect power supply by the power switch on the casing, light-operated head on photoswitch circuit and the support cooperates, the rotation of control motor, and by the rotation of decelerator drive eccentric shaft, coaxial hard-wired eccentric bushing crank end then drives the upper holder block and the lower lock block that pass through the spring connection that are installed in the frame chute and does straight reciprocating motion along runner wall on eccentric main axis, utilization be installed on the lower lock block last die be installed in support on sphere under die cooperate and contact, finish seal and move.On last lower lock block contact plane; the center that all is designed to is inwardly recessed; the spill plane that the edge can contact; when the stressed contact of last lower lock block; between last lower lock block contact-making surface, form a gap; utilize this gap to make lower lock block produce compressive deformation; the lower lock block longitudinal size is dwindled with the increase of pressure; the elastic deformation amount who produces has played the automatic compensating action of impression thickness; make the impression of being opened by platen of different-thickness can both be clear; the application of this structure simultaneously also can improve the power and the rotating speed of driving motor; and it is stressed excessive and damage that impression mechanism is produced; and be installed in the structure that cooperates the holder of mounting spherical seal under the sphere on the support in the die; then played the automatic leveling effect of sphere; also reduce the difficulty of die Installation and Debugging; under the effect of pressure; the holder of sphere seal can be slided with one heart along following die Internal Spherical Surface; unbalanced automatic leveling seal holder plane according to pressure; improve the impression quality; in automatic moulding process; in order to prevent that electromotor overload from damaging; this machine is provided with the automatic overload protection circuit; by transformer B2 current of electric is implemented monitoring at any time; when motor working current surpasses normal value; transformer B2 with current changing signal through bridge rectifier; potentiometer RW; diode D6 delivers to by resistance R 10; the amplifying circuit that R11 and triode V3 form; and the signal of telecommunication after will amplifying by amplifying circuit; deliver to by IC2; the shaping on-off circuit that diode D7 forms; through diode D8; tend to act negative-phase relay J2 action of triode V4; overload light is bright; relay J 1 is opened circuit in advance; J2 turn-on reversal circuit has been realized the auto-reverse of motor, and protection motor and whole machinery are not damaged.

When use manually impresses function, two utmost point reinforcements that utilization is provided with on lower lock block manually impress mechanism, man-operated mechanism is by the depression bar that is fixed on above the lower lock block, Jiao Jie push rod with it, connect to form with the manual depression bar and the manual last item of push rod hinge joint, manually can adorn handle on the last item, turning handle drives manual depression bar and rotates, promoting push rod slides to the depression bar direction, and formation gusseted, promoting depression bar moves to the lower lock block direction, and formation reinforcement angle promotion lower lock block moves downward, finish moulding process, because man-operated mechanism has formed two triangle reinforcements supports when impression, therefore can obtain reinforcement twice, make manual impression strength suitable, alleviate the pressure that imposes on handle with automatic impression strength.

Owing to adopted above-mentioned impression thickness automatic compensation structure; the automatic leveling structure of sphere seal holder; the feasible speed of imprint that the utlity model has is fast; high efficiency; impression is advantage clearly; and the impression of suitable different-thickness paper; and the manual force-increasing mechanism that is adopted; not only laborsaving, also can obtain the technique effect that is equal to the motor machine impression, in photoswitch circuit, increased automatic protection circuit; realize that overload protection then makes the utility model long service life; fault rate is low, and the utility model not only is suitable for file process in enormous quantities to be used, and also can be widely used in the file process of small lot.
