Technical Field

The utility model belongs to the technical field of packaging machinery, and particularly relates to a staple label folding machine capable of continuously supplementing cards.

Background

The staple folding machine is a packaging machine and is commonly used for products such as towels, socks, gloves and the like. The basic action process is to take printed paper cards with certain thickness and hardness as packaging materials, fold the paper cards at set positions, fold the rectangular paper cards into U-shaped, then plug the articles to be packaged into the openings of the U-shaped cards, and then drive in glue needles by using glue needle guns to fix the two ends of the U-shaped cards and the packaged articles together. The automatic staple label folding machine mainly comprises a step of folding paper cards into U-shaped cards.

This step can also be broken down into two steps, firstly extracting a single card from a stack of cards, typically hundreds to thousands; the card is then folded into a U-shape.

CN214649625U discloses an automatic card feeding, folding and stapling machine, which comprises a frame, wherein an electric cabinet is arranged at the bottom of the frame, and a table top plate is arranged at the top of the frame; the left part of the table panel is provided with a paper card storage module, the right side of the table panel is provided with an opening area, and a translation sliding rail module is arranged at the lower side of the opening area; a paper card folding mechanism is arranged on the translation sliding rail module; the paper card sucking mechanism comprises a horizontal sliding rail module, a vertical cylinder is arranged on the horizontal sliding rail module, and is connected with a sucker fixing block and fixedly provided with a sucker; the marking mechanism is fixed on the portal frame above the opening area of the table panel. During operation, the paper card suction mechanism picks up the paper card through the sucker and sends the paper card to the top plate of the paper card folding mechanism through the horizontal sliding rail module. That is, in order to extract a single paper card, the prior art adsorbs one paper card at a time by means of suction by a suction cup.

CN216333304U discloses a card folding mechanism of a card sender for a packaging machine, which comprises a frame, a turntable structure and a card folding station, wherein the turntable structure and the card folding station are both arranged on the frame; the turntable structure is used for moving the card to be bent to the card folding station and removing the bent card from the card folding station, and a plurality of suction nozzle assemblies which are uniformly distributed in the circumferential direction and are used for sucking the card are arranged on the turntable structure; the folding station comprises a pressing structure and a folding structure, the pressing structure is used for pressing the card on a suction nozzle component located at the folding station, and the folding structure is used for bending the card located at the folding station. When the servo motor works, the servo motor can drive the input shaft of the cam divider to rotate, the output shaft of the cam divider can drive the rotary table to rotate, and when the rotary table rotates, the rotary table can drive the suction nozzle assemblies to rotate, so that the suction nozzle assemblies can move the card to be bent to the card folding station and can move the bent card away from the card folding station. It can be seen that, in order to extract a single paper card, the prior art also uses a suction cup to suck one paper card at a time.

The adsorption mode in the prior art can ensure that one paper card is extracted each time, but the paper card is required to be conveyed to a designated working position after adsorption, and the motion of the sucker is controlled by a motion mechanism; in short, the action process of generating negative pressure, moving the suction cup, eliminating the negative pressure and resetting the suction cup is needed, and the process takes a long time, so that the whole efficiency of the machine is slowed down. On the other hand, when the whole stack of paper cards is folded, a new stack of paper cards needs to be replenished to a storage position, and at this time, the machine needs to be stopped, a new paper card needs to be replenished, the position of the paper card is carefully corrected, and then the machine is restarted, and the machine efficiency is also affected in the process.

When the utility model works, the stacked paper cards are placed on the paper card storage unit formed by surrounding the two side walls, and are also on the conveyor belt; the screw rod sliding block mechanism is adjusted to enable the distance between the two side walls to be proper; the stack of cards is moved forward by the conveyor belt. Since the rear ends of the side walls form a flare, the card is not required to be precisely aligned when placed, and the card is automatically aligned to a set position during the forward movement. In the process of forward movement of the whole stack of paper cards, the pre-separating baffle is touched, most of the paper cards of the whole stack are blocked by the pre-separating baffle due to a certain gap between the pre-separating baffle and the worktable, and the bottommost paper cards can continue to travel along with the conveyor belt; through a plurality of pre-separating baffles and the adjustment of the heights of the pre-separating baffles, the gap between the final pre-separating baffle and the conveyor belt is 1-2 times of the thickness of the paper card, so that only one paper card can be output. The friction wheel is also adjusted in height to enable the gap between the friction wheel and the conveyor belt to be 1-2 times of the thickness of the paper card, and at the moment, the friction wheel rotates reversely, so that the fact that the penultimate paper card is pushed back into the paper card stack can be better ensured, and only the lowest paper card is output to the next link.

Therefore, the scheme of the utility model is that the lowest paper card is extracted one by one, so that the paper card is replenished from the upper part of the stack, and the card replenishing operation can be carried out at any time without waiting for the end of a stack of paper cards and stopping; meanwhile, alignment is not needed during card supplementing, and operation is more convenient.
