Technical Field

The invention relates to an type stamping machine.

Background

For raise the efficiency and reduce intensity of labour, adopt electronic seal machine mostly, through driving motor and link mechanism's cooperation in order realizing that the seal subassembly reciprocates, long-time back of using, seal or link mechanism can wear and tear, can make the seal of adding the lid unclear, current seal machine life is shorter.

The existing stamping machine can only be used for stamping paper with thicknesses, if the paper with other thicknesses is replaced, the paper is easily crushed or the stamping is not clear, the control of stamping stroke can be realized by adjusting the rotating number or the angle of the output shaft of the driving motor, but the control precision is poor, and the stamping is still unclear.

Disclosure of Invention

The invention aims to provide stamping machines which have long service life and are convenient for stamping stroke adjustment.

types of stamping machines comprise a bottom plate, wherein a fixing frame is arranged on the bottom plate, a stamp assembly is arranged above the bottom plate and comprises a lifting nut and a stamp, the lifting nut is provided with an inner thread groove, a lead screw is matched in the inner thread groove, a bearing is fixed on the fixing frame, the lead screw is fixed with an inner ring of the bearing and is linked with a driving mechanism, and a guide structure which is matched with the lifting nut to limit the rotation of the lifting nut is arranged between the fixing frame and the lifting nut.

When the stamping machine is used, the driving mechanism drives the screw rod to rotate, so that the lifting nut is driven to move up and down, the stamping is pressed down and reset, the abrasion between the screw rod and the lifting nut is extremely small, and the service life of the stamping machine is longer. The invention adopts a screw rod transmission structure, can ensure that the control precision of the stamping stroke of the stamp is higher, and can ensure that the stamp machine can be used for stamping and stamping paper with different thicknesses only by changing the rotation times or the number of turns of the output shaft of the driving mechanism. The invention can also be used for stamping the steel seal, and the stamp is only required to be replaced by the upper steel seal die and the corresponding lower steel seal die is arranged on the bottom plate.

Preferably, the guide structure comprises a guide groove which is vertically arranged and a guide post which extends into the guide groove, a fixed plate is fixed on the fixed frame, the fixed plate is provided with the guide groove, and the guide post is fixed with the lifting nut. The lifting nut is limited by the arrangement so as to avoid rotation of the lifting nut.

Preferably, the fixing plates are provided on both opposite sides of the lifting nut, the lifting nut includes an upper lifting block having a fixing groove penetrating vertically and a nut socket fixed in the fixing groove and having the female screw groove. The above arrangement facilitates replacement of the lead screw and nut socket. The invention can be used in different types of seal machines except for the driving mechanism, the lead screw and the nut, so as to be convenient for production and manufacture.

Preferably, the outer edge of the vertical section of the part of the guide post located in the guide groove is circular. The arrangement reduces the contact area between the guide post and the groove wall of the guide groove, so as to ensure the stamping precision of the stamp.

Preferably, the bearing is fixed on a bearing seat, and the bearing seat is positioned between the two fixed plates and fixed with the fixed plates. The arrangement makes the assembly of the stamping machine more convenient.

Preferably, a lower lifting block is arranged on the lower side of the lifting nut, a plurality of connecting columns are fixedly connected between the lifting nut and the lower lifting block, the seal is fixed on the lower side of the lower lifting block, the lead screw is located above the lower lifting block, and the seal is located under the lead screw. The seal and the screw rod can be coaxially arranged by the arrangement, so that the stamping precision of the seal is ensured.

Preferably, the driving mechanism comprises a driving motor, an output shaft of the driving motor is vertically arranged and fixed with the driving wheel, a driven wheel is fixed on the screw rod, and a belt is sleeved on the driving wheel and the driven wheel.

The invention has the advantage of longer service life, and can be used for stamping on paper and plastics with different thicknesses.
