Forward and reverse differential transmission mechanism and drug bottle delivery device

Abstract

The invention relates to a transmission device for a packaging machine, in particular to a forward and reverse differential transmission mechanism and a medicament bottle conveying device. The forward and reverse differential transmission mechanism and the medicament bottle conveying device aim to solve the problems that in the prior art, a ratchet of a ratchet wheel is not ingenious, unequal amplitude motion is difficult to achieve, and for a corresponding injection bottle conveying device, a motor burns due to forwards and reverse rotation and bottles are not stacked orderly when transported. According to the forward and reverse differential transmission mechanism, the direction in which a ratchet fixing assembly drives the ratchet wheel to rotate intermittently is opposite to the direction in which a main shaft is driven to rotate when an overrun clutch is locked in a unidirectional mode. The forward and reverse differential transmission mechanism and the medicament bottle conveying device have the advantages that the structure is ingenious and the application range is wide; the motor rotates forwards all the time to avoid motor burning caused by forward and backward rotation of the motor; the speed difference produced in the working process of a conveyor belt is adjusted through a ratchet wheel cover, and feeding and retreating are switched easily; the speed of the conveyor belt is adjustable; frequency and amplitude of an input system of the motor are adjustable, and the flexibility of the system is improved.

Description

technical field [0001] The invention relates to a transmission device for a packaging machine, in particular to a forward and reverse differential transmission mechanism and a medicine bottle delivery device. Background technique [0002] In variable speed transmission devices, most of the methods that can be used are differential gears, planetary gears or continuously variable speeds. These devices have high requirements on size and relatively high cost. Therefore, technicians in related industries have begun to study relatively low-cost equipment. The ratchet and ratchet transmission mechanism is used to complete the forward and reverse differential transmission. [0003] Ratchet and ratchet transmission are mostly used to complete the intermittent feed of the mechanism. It is a common transmission method in the mechanical field. It is also introduced in books and textbooks on various mechanical designs and mechanical principles. The existing ratchet and ratchet transmiss...

Problems solved by technology

[0007] In the application of the existing technology, the following deficiencies are found: 1. Manual adjustment is required, which is a waste of labor; 2. Although the forward and reverse motor can solve the problem of uneven stacking, it will damage the motor very much, which is what the industry says "Burning the motor" will result in higher cost of use and maintenance delays; 3. When the output speed of the motor is constant, it is difficult to adjust the speed and frequency of the driving roller, and it can only follow the speed of the motor; 4. At the end of the working process, when the conveyor belt is pushed out, if the existing technology is used to exit directly, the unpacked bottles conveyed will be dumped, and the consequences will be damaged if serious consequences are caused; If the single amplitude is not equal, it is necessary to use frequency conversion, electronic control and other devices to increase the cost
