Floating roller traction drive card collecting machine used for collecting cards of different thicknesses

Abstract

The invention discloses a floating roller traction drive card collecting machine used for collecting cards of different thicknesses. The card collecting machine comprises a casing, a card holder, a mounting substrate, traction devices, a card collecting device, a drive device and a control device. The mounting substrate is provided with a pair of traction bearing. Each traction device comprises a front channel roller, a front floating roller, a front floating plate and a torsion spring. The front channel rollers, the front floating rollers and the front floating plates are arranged on the traction bearings. The front channel rollers, the front floating rollers and the front floating plates are in meshed transmission through gear groups. The front floating plates are hinged on the traction bearings. Each traction bearing is provided with a gap. Each front floating roller is erected on a front floating plate, and is supported in a gap. The front floating rollers and the front floating plates are connected. A card-collecting channel is formed by a gap between each front floating roller and each front channel roller. The torsion springs are arranged on the traction bearings. Each front floating plate is pressed by the projecting end of a torsion spring. The card-collecting machine is capable of adjusting the gap of a card-collecting channel, and is suitable for the cards of different thicknesses.

Description

technical field [0001] The invention relates to a card machine, in particular to a floating roller traction-driven card machine for collecting cards with different thicknesses. Background technique [0002] With the rapid development of science and technology, a large number of card transceivers are used in the management of vehicle traffic in expressways and residential areas. Due to the large thickness span of the access cards on the market, ranging from 0.9mm to 6mm, the channels of card transceivers currently on the market are generally The design is simple, and the compatibility with the thickness of the card is poor, and some product channels are designed to be compatible with the thickness of the card as a one-way wheel drive channel to suck the card, which is prone to problems such as card slipping and jamming. At the same time, when swiping business cards or stored value cards, It is necessary to put the card into the channel, swipe the card and then spit it out, wh...

Problems solved by technology

[0004] But the traction device in the existing card collecting machine adopts upper and lower two rollers to pull and drive the card, and the rollers rotate to realize the traction of the card, and the gap between the upper and lower two rollers constitutes the card collection channel of the card, but The rollers can only rotate around the axis and cannot float up and down. Therefore, the gap between the two rollers is fixed and cannot be suitable for cards of different thicknesses.

[0005] At the same time, the existing traction device generally only has one set of rollers, and the bite force between the rollers and the card is relatively small, and the card is easy to slip, resulting in unstable card output

At the same time, when swiping stored-value cards and business cards, you need to put the card into the channel for reading, which greatly affects the work efficiency
