Description

A card scraping device and a card sending system using the card scraping device

technical field

The patent of the present invention relates to mechanical components of card sending and processing equipment, specifically a card scraping device.

Background technique

The traditional way of sending cards is mainly friction. A rubber wheel is used to rub the card out of the ticket box. The rubber wheel has a serrated rubber protrusion on one circle. When the rubber wheel is pressed on the card, the mechanism rotates the rubber wheel. The card is taken out of the ticket box by using different friction forces on the upper and lower sides of the card. The disadvantage of this sending method is that it is relatively easy to slip and scratch the surface of the card, resulting in a shortened service life of the card.

Detailed ways

Referring to Fig. 1, the card sending system of the present invention includes a card scraping device 100, a card storage box 200 and a main channel 300, wherein the card scraping device 100, as a transmission device, can be installed on the card storage box 200, and the card scraping device 100 can be installed on the card storage box 200. The feeding device 100 scrapes the card media built in the card storage box 200 and leads them out neatly through the main channel 300 .

Referring to FIGS. 2 to 4 , the card scraping device 100 includes a transmission gear 1 , a rotating shaft 2 , a motor 3 , two timing pulleys 4 , a timing belt 5 , a channel 6 and a card scraping block 7 . Among them, the transmission gear 1 is fixed in the inner chamber of the card scraping device 100 through a rotating shaft 2 passing through it; the motor 3 is built in the card scraping device, and a top arm protrudes from its end, and is supported by the top arm A synchronous pulley 4, in addition, one end of the rotating shaft 2 also supports another synchronous pulley 4, and the synchronous belt 5 that is wound and tensioned on it is mutually transmitted between the two synchronous pulleys 4, like this, wherein A synchronous pulley 4 rotates under the drive of the motor 3, and under the traction force of the synchronous belt 5 wound between the two synchronous pulleys 4, it drives the other synchronous pulley 4 to rotate, thereby driving the rotating shaft 2 and the Transmission gear 1 on it rotates synchronously. The channel 6 is located at the bottom of the card scraping device 1 , it is perpendicular to the transmission gear 1 , and its width is roughly adapted to the maximum width of the card medium. The card scraping block 7 is installed on the passage 6, and a stepped protrusion is attached on it. The protrusion of the card scraping block 7 is lower than the upper plane of the passage 6, and the height of the protrusion is less than the thickness of a card. When a card is sent out by the card storage box 200, the card scraping block 7 can scrape the tail end of a card that is pressed onto the upper plane of the passage 6, and will not scratch the next one, causing two cards to be scraped out together The phenomenon. When the card scraping block 7 is in the recovery position, the spring (not shown) in the card scraping block 7 can ensure that the card scraping block 7 is rotated upwards and lifted during the return trip, so that the surface of the card can not be damaged.

In one embodiment of the present invention, the card scraping device 100 also includes a card scraping rack 8, through which four bearings installed on it go back and forth to the passage 6, and are connected with the transmission gear 3 perpendicular to the passage 6 Mesh.

In another preferred embodiment of the present invention, the card scraping device 100 also includes sensors 9, which are arranged on the left and right sides of the scraping block 7 for judging the position of the scraping block 7. When the card moves away from the initial position, the motor 3 reversely pushes the card scraping rack 8 to send the card scraping block 7 back to the initial position to wait for the next card to be sent to ensure the continuous operation of card sending.

In yet another preferred embodiment of the present invention, the card scraping device 100 is further provided with channel height adjustment blocks 10, which are arranged on the bottom surface or both sides of the channel 6 for adjusting different channel heights to match cards of different thicknesses.

It can be understood that the card scraping device 100 of the present invention can also omit the timing belt 5, and the two timing pulleys 4 are gears meshing with each other, and the motor 3 drives the timing pulley 4 to drive the rotating shaft and the transmission gear 1 to rotate synchronously.

The working principle of the card scraping device of the present invention is briefly described below:

When the card is pressed onto the upper plane of the channel 6 from below, the motor 3 starts to rotate in the forward direction, driving the timing pulley 4 and the timing belt 5, thereby driving the transmission gear 1 to work, and the rotation of the transmission gear 1 is transformed into meshing with it The parallel movement of the card scraping rack 8 and the card scraping block 7 on it, at this time, since the card scraping block 7 is attached with a stepped protrusion, the protrusion scrapes the tail end of the card, and the card is close to the channel 6 The upper plane of the main channel 300 is brought out. And, the position of the card scraping block 7 is judged by the sensor 9 on the device. When the card scraping block 7 reaches the position, the motor 3 reverses and sends the card scraping block 7 back to the initial position, waiting for the next card send. In addition, the channel height adjustment block 10 can adjust different channel heights to match cards of different thicknesses, so that the scraping method using the tail end of the card as the focus point avoids damage to the card surface, thereby improving the service life of the card and increasing the success of sending the card Rate.

The above disclosure is only a preferred embodiment of the card scraping device of the present invention, and of course it cannot limit the scope of rights of the present invention. Therefore, the equivalent changes made according to the patent scope of the present invention are still covered by the present invention. scope.
