AI Technical Summary
The ears of existing bag packaging are opposite to the bag mouth of the bag, which leads to the bag mouth of the bag being opened passively when the bag is hung for a long time or with heavier weight, resulting in the problem of the packaging falling into the ground.
In the bag packaging production process, a new process step is designed: the upper and lower ends of the plastic film are folded outwards, the tongue is flipped upwards and fits the hanging ears, and the double-sided adhesive is pasted on the upper part of the folded outer end of the plastic film. The packaging bag is formed by transverse heat sealing and cutting. The tongue is connected to the side of the hanging ears and then interrupted, so that the tongue is restored to the free state and is adhered to the double-sided adhesive to seal.
The bag packaging with the same direction as the hanging ear is realized, avoiding the problem of passive opening of the packaging bag mouth and ensuring the safety and stability of the packaging during the hanging process.

[0001] The invention relates to a production process and equipment for bagging packaging. Background Art
[0002] At present, the hanging ears of the bag (used to be hung on the hanging rod of the cabinet for product display) of the bag on the market are opposite to the loading direction of red envelopes, cards, books and other materials from the bag mouth, that is, the hanging ears are set at the bottom of the bag, which is exactly opposite to the bag mouth direction of the bag; and the bag mouth of the bag packaging is usually sealed by using the tongue inside the bag mouth to be glued to the front side of the bag mouth with double-sided tape after the material is loaded. Therefore, when such bag packaging is hung in a store or a cabinet of a store for display or for sale, if it takes a long time and the weight of the package in the bag is heavy, the double-sided tape will weaken, and the bag mouth of the bag will be passively opened, and the package in the bag will fall to the ground.

[0015] The tongue-upturning mechanism 6 comprises an upward folding plug plate 61 installed along the plastic film conveying path, and the head of the upward folding plug plate 61 faces the root of the ear hook when in operation. The tongue-adhering ear hook mechanism 8 comprises a guide roller 82 and a pressing wheel 81, and the pressing wheel 81 is located above the guide roller 82, and the axis of the pressing wheel 81 is inclined to the guide roller 82, so when the pressing wheel 81 presses the tongue of the plastic film against the surface of the guide roller 82 for transmission, it will generate an upward pulling force on the tongue, so that the turned-up tongue can completely fit the ear hook. The breaking mechanism 13 includes a fixed support 27, on which a left knife 21 and a right knife 22 are arranged. The left knife 21 and the right knife 22 are pushed by a knife cylinder to perform an inward-outward cutting action. The left knife and the right knife are symmetrically arranged. The left knife and the right knife respectively have a blade portion and a handle portion 23. The blade portion and the handle portion are L-shaped. The connection position of the blade portion and the handle portion 23 can be swung on the fixed support 27 through a swing shaft 24. The knife cylinder is divided into a left knife cylinder 25 and a right knife cylinder 26.

[0016] Figure 1The bagging packaging shown is produced as follows: the unloading traction mechanism pulls and conveys the plastic film on the plastic film unloading mechanism (at this time, the upper and lower ends of the plastic film have been folded outwards respectively, the upper folded part covers the lower folded part, and the middle position of the upper folded part has a longitudinal indentation line, the part above the longitudinal indentation line is the ear hanging part, and the part below is the tongue part), the plastic film passes through the film material floating tensioning mechanism and the film material deviation correction and tracking mechanism, and the ear hanging part is punched by the punching mechanism to form a hanging hole; during the traction process, the plastic film will pass through the tongue flipping mechanism and the tongue close to the ear hanging mechanism, and at the tongue flipping mechanism, The upward folding plug makes the tongue part flip up, and when the tongue is close to the ear hanging mechanism, the pressure wheel presses the tongue part of the plastic film against the surface of the guide roller. As the pressure wheel and the guide roller rotate, the pressure wheel pulls the tongue part upward so that the flipped tongue part is completely attached to the surface of the ear hanging part. At the same time, the double-sided tape released by the double-sided tape feeding mechanism is pasted on the space left after the tongue part is flipped up, that is, the double-sided tape is pasted on the upper part of the outer fold of the lower end of the plastic film (the position was originally blocked by the tongue part); then, under the intermittent traction of the stepping traction mechanism, the plastic film is sent out at a fixed length and is sealed by the transverse heat sealing mechanism. It is heat-sealed and cut to form a single packaging bag and fall onto the packaging bag conveying platform. At this time, the tongue and the ear are connected at the sides due to transverse heat sealing, in order to keep the bag mouth open; on the packaging bag conveying platform, the packaging bag is intermittently conveyed and passes through the bagging packaging mechanism, the interrupting mechanism and the sealing mechanism in sequence. At the bagging packaging mechanism, red envelopes, cards, books and other materials are put into the packaging bag in a bagging packaging manner. At the interrupting mechanism, the pressure block first presses down to press the packaging bag in place, and then the upper and lower suction cups act, and the upper suction cup pulls the tongue upwards. , the lower suction cup pulls the ear hanging part downward to form an opening between the tongue part and the ear hanging part that were originally fitted, so that the left and right knives can enter. Then the left knife cylinder and the right knife cylinder are activated to push the left knife and the right knife into the above-mentioned opening and cut and interrupt the tongue part connected to the side of the ear hanging part from the inside to the outside, so that the tongue part recovers to a free state and tilts upward. At the sealing mechanism, the roller brush cylinder pushes the roller brush forward, and the roller brush pushes the tongue part toward the bag opening of the packaging bag, so that the tongue part adheres to the double-sided tape, and then the packaging bag is sealed, completing the automatic production of bagging with the bag opening and the ear hanging direction in the same direction.
