Description

One kind point card conveyer

Technical field

The utility model is related to a point card conveyer.

Background technology

Card labelling machine is that sheet is labelled.Its applicable industry includes the row such as electronics, hardware, plastic cement, chemical industry Industry, application example has cardboard, acrylic plate, big plastic parts and potsherd, and applicable label mainly includes adhesive label, do not done Glued membrane, electronic supervision code, bar code etc..

Chinese Patent Application No. be 201420535117.5 applyings date be 2014.9.17 patent document China disclose A kind of high-speed card labelling machine, including header, card separating mechanism, belt-type feed mechanism, receiving mechanism and electric cabinet.

The card separating mechanism includes feed well, set between the two side of feed well the first opposite thumb wheel of rotation direction and Second thumb wheel, the first thumb wheel and the second thumb wheel in the vertical direction are shifted to install, when multiple stacking cards be put into feed well, First thumb wheel rotate the card of bottommost is pushed on the conveyer belt, the second thumb wheel transfer by its in card reverse.This point Mechanism for card, only the first thumb wheel, which are realized, dials card motion, and the reliability for dialling card is not high, in order to avoid multiple cards are transferred to, and sets Second thumb wheel, but the first thumb wheel is located at the side of the second thumb wheel, and the card transferred to through the first thumb wheel is passed through into the second thumb wheel Reverse, then can be limited by the direction of rotation of the first thumb wheel and be difficult to reverse card.In addition, the width of feed well can not be adjusted, So, different size of card cannot be applied to.After card is positioned in feed well, card is difficult to enter the first thumb wheel Place, is transferred to card by the first thumb wheel, the axle center of the first thumb wheel and the second thumb wheel is all fixed, it is thus impossible to first Thumb wheel and the second thumb wheel are adjusted, it is impossible to transferred to suitable for the card of different-thickness.Described card separating mechanism is sent with belt-type Expect that mechanism is relatively-stationary, it is thus impossible to the position of integrated regulation card separating mechanism.
