Stamper printing mechanism

Abstract

A stamping mechanism of a stamp machine, comprising a sliding frame, a stamping shaft part and a swing bar part, the sliding frame includes a sliding part, an upright part fixed on the upper side of the sliding part, fixed on the upright part horizontally and arranged at intervals A pair of guide posts; the stamping shaft part includes a stamping shaft, a connecting piece fixedly connected to the upper part of the stamping shaft and an elastic reset device; the swing link part includes a drive shaft, a swing link connected to the drive shaft and a swing link connected to the swing The rolling body on the upper part of the rod; the upper end of the swing rod cooperates with the inner side opposite to the guide column, and the sliding frame is moved back and forth between the imprinting position and the reprinting position; On the mating surface, when the stamping shaft is pressed down by the upper rolling body of the swing bar at the stamping position and the reprinting position, the upper end of the swing bar breaks away from the cooperation with the guide post. The invention improves the stamping accuracy of the stamping machine, realizes the pad printing action and stamping action driven by a single motor, simplifies the structure of the stamping machine, reduces the volume of the stamping machine, has simple structure and reliable action.

Description

technical field [0001] The invention relates to a stamp machine, more specifically, to a stamping mechanism of the stamp machine. Background technique [0002] The stamping shaft of the stamping machine is slidably connected to the frame, and its lower end is fixedly connected with a stamping head, and the stamping head realizes stamping by moving up and down of the stamping shaft. The stamping shaft of the existing seal machine is driven by a connecting rod with one end connected to the upper end of the stamping shaft and the other end connected to the cam. The rod moves, and the connecting rod drives the stamping shaft to move up and down. [0003] When the cam rotates to drive the connecting rod to move, the connecting point of the connecting rod and the cam moves in a circle with the cam, and the connecting rod not only moves up and down with the connecting point, but also swings around the connecting point at the upper end of the stamping shaft. Including the lateral ...

Problems solved by technology

However, this dual-axis structure does not fundamentally change the micro-movement of the stamping head, and at the same time, the structure is more complicated and prone to failure

[0005] In addition, in order to realize the pad printing action and the stamping action of the ink pad preset on the stamping head, the existing stamping machine uses two motors to drive separately, resulting in a large volume and complicated structure of the stamping machine
