A kind of binding machine and its driving mechanism

Abstract

The invention discloses a driving mechanism of a binding machine. The driving mechanism of the binding machine comprises a driving shaft subassembly and a connecting rod subassembly, wherein the driving shaft subassembly comprises a pull rod and a driving block; the driving block is arranged on a driving shaft; one end of the pull rod is hinged to the driving block; the other end of the pull rod is connected with a manipulator; the connecting rod subassembly comprises a driving rod, a pressing rod and a connecting rod; one end of the driving rod, one end of the pressing rod and one end of the connecting rod are hinged to one another; the other end of the connecting rod is hinged to a rack; the other end of the pressing rod is hinged to a viscous shearing mechanism; and the other end of the driving rod can be matched with the driving block. In a rotating process of the driving block, the driving rod drives the viscous shearing mechanism to respectively forwards move by a preset distance twice sequentially. When the driving shaft rotates clockwise, the driving block drives a manipulator through the pull rod, and the connecting rod subassembly drives the viscous shearing mechanism; and when the driving shaft rotates anticlockwise, the driving block sequentially drives the various components to reset, in a working period, the load of a power source is balanced, the driving efficiency is improved, the power of a motor is reduced, the mechanism is simplified, and the size of the mechanism is reduced. The invention also discloses a binding machine.

Description

technical field [0001] The invention relates to the technical field of financial machines and tools, in particular to a bar tie machine and a driving mechanism thereof. Background technique [0002] With the rapid development of the economy, the bank's cash processing business has increased significantly. In order to process business quickly, efficiently and accurately, financial instruments such as banknote counters and bar binding machines have emerged as the times require. [0003] The binding machine is usually used in conjunction with the banknote counting machine to bundle the banknotes counted by the banknote counting machine into handles. The binding machine includes a retracting mechanism, a sticking and cutting mechanism and a driving mechanism. The retracting mechanism is used in conjunction with the paper tape wheel and the paper tape frame to release the paper tape on the paper tape wheel and make the paper tape wrap around the banknotes at an appropriate length...

Problems solved by technology

The load of the motor in one cycle of the cam is unbalanced. During the lift, it not only needs to do work on the driven part, but also compresses the return spring to store energy for the driven part to return. During the return trip, there is no need to do work or even negative work, and the power of the motor is required. Larger, louder noise, lower working efficiency of the motor, and unbalanced load during the working process of the motor, which will affect the life of the motor, and then affect the reliability of the driving mechanism

[0008] During the working process of the cam mechanism, due to the characteristics of the cam mechanism, the stroke of the driven part is small. In order to meet the stroke requirements of the manipulator 5', the size of the first group of cam mechanisms is larger, which increases the volume of the tie-down machine

At the same time, the pull wire is a flexible mechanism that can only be driven in one direction, and it needs to be equipped with auxiliary tools such as pulleys and pull wire sleeves.
