Ticket card conveying mechanism of ticket selling machine

Abstract

The invention discloses a ticket card conveying mechanism of a ticket selling machine, which is characterized in that a stepping motor (27) is fixed on a vertical plate; a transmission assembly (4) is connected to the stepping motor (27) and drives three driving wheels (2-1), (2-2) and (2-3); the transmission assembly (4) is also connected with two driven wheels (5) and (10); the two driven wheels (5) and (10) respectively correspond to the former two driving wheels (2-1) and (2-2); two driven wheel shafts (6) and (11) are respectively fixed on two crank arms (7) and (9) through two bearings; the two crank arms (7) and (9) are connected to a middle supporting shaft (8) fixed on the vertical plate through the bearings, and are provided with a wobble wheel (14) corresponding to the third driving wheel (2-3) which is fixed on a wobble wheel shaft (13); and the wobble wheel shaft (13) is connected to a wobble wheel supporting shaft (12) fixed on the vertical plate through the bearings. In the ticket card conveying mechanism, a rolling wheel type conveying mode which has the advantages of good conveying effect, reliable effect, long service life and quick response time, and is convenient for maintenance is adopted, and a spring pretensioning device is provided to adjust the pressure among the driving wheels and the driven wheels by set screws on the upper end of a knob so as to guarantee good clamping state of a rolling wheel.

Description

Technical field: [0001] The invention relates to a ticketing system applied in rail transit, in particular to a ticketing ticket card transmission mechanism. Background technique: [0002] At present, the device for selling tickets and ticket cards is mainly composed of a ticket-card take-out mechanism, a ticket-card conveying mechanism, a ticket-card reading and writing device, and a ticket-card shunting device. In these links, the reliability and response time of the ticket card transmission mechanism directly affect the entire process of ticket sales. Most of the existing ticket card transmission mechanisms use conveyor belts to transport tickets, but the conveyor belts still have deficiencies in actual use. [0003] 1. The friction between the conveyor belt and the ticket is not uniform, which affects the positioning accuracy of the ticket. [0004] 2. The friction force is too small to send out the ticket normally. [0005] 3. Excessive friction will cause the ticket...

AI Technical Summary

Problems solved by technology

[0003] 1. The friction between the conveyor belt and the ticket is not uniform, which affects the positioning accuracy of the ticket

[0004] 2. The friction force is too small to send out the ticket normally

[0005] 3. Excessive friction will cause the ticket to bend and reduce the service life of the ticket

[0006] 4. The conveyor belt wears a lot during high-speed operation, and its service life is greatly shortened

[0007] 5. Due to the life of the belt, the maintenance cost of the equipment is relatively high
