Description

Transverse punching type card automatic puncher

The present invention relates to a kind of pattern plate punching device, particularly dynamo-electric automatic punching device.

Existing automatic card-punching machine, Washdown type 16 pin automatic card-punching machines that provide as Chinese patent CN91107400.7, comprise support, the cardboard propulsive mechanism, the cardboard stepping mechanism, punching punch block and electromagnet help inhales mechanism, adopt 16 towards pin (not containing the favourable opposition pin), textile design as requested, provide energising or no power information by electronic computer to electromagnet coil, help suction mechanism that armature is close to iron core in advance, after a while if coil electricity, then accordingly towards the pin punching, if the coil no power its accordingly towards not punching of pin, be provided with to help and inhale mechanism and can reduce the coil power consumption significantly, help to improve the reliability of complete machine work simultaneously, reduce wrong flower rate effectively, the cardboard propulsive mechanism one by one flows to the cardboard stepping mechanism with cardboard.This scheme remains in following defective:

1. punching efficient is low, and punch block up and down reciprocatingly once can only dash 16 holes, is used to make nominal 1400 pin cards, per hour can only punching out 198;

2. a cardboard propulsive mechanism must be set, one by one carry cardboard, become cardboard, when being applied to weave, need again many pieces of card is connected in series use, cause waste thus for the punch block punching out to stepping mechanism;

3. owing to have the cardboard propulsive mechanism, machine volume is bigger, and weight is difficult to further alleviate;

4. the electromagnet of Cai Yonging is a discrete, and processing capacity is bigger, makes troubles to installation simultaneously.

The purpose of this invention is to provide a kind of high efficiency transverse punching type card automatic puncher, save the cardboard propulsive mechanism, be provided with towards pin 2 * 84 pins, machine volume is little in light weight.

Realize that the object of the invention adopts following technical measures:

1. adopt 2 groups of integral electromagnets, the yoke of each group and iron core are made with a block of material, and be easy to process, the precision height, and volume is little, and is easy for installation.Arrange 2 groups of eedles and towards pin, the punch block reciprocating motion once, the simultaneously horizontal 2 row's pits of going out improve operating efficiency.

2. adopt to help and inhale mechanism, eliminate the air gap of electromagnet core and armature residual gap, make the electric current of electromagnet coil power reduce to bottom line, improve the reliability of iron core, armature adhesive simultaneously.

3. punch block pumps and realizes that by the support spring that is arranged in cam on the main shaft and supporting plate bottom structure is light and handy, and reciprocating movement displacement small frequency height is beneficial to further and increases work efficiency.

4. for eedles back-moving spring is set and, is used to eliminate the misoperation that punching may occur for jumper bar is provided with limiting plate; Help the montant adjustable length of inhaling mechanism, guarantee to help to suck entirely effectively.
