Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing equipment, and more specifically, in particular to a packaging bag fast printing and stripping integrated processing machine. Background Art

[0002] Packaging bags are used to hold and store all kinds of items. They are widely used in the production, circulation and sales of goods. Packaging bags come in a wide variety of specifications, and different goods can be matched with different types of packaging bags according to needs.

[0003] In food sales, since food has a high demand for sealing and ready-to-eat properties, quick-fold seal packaging bags are becoming more and more popular with merchants and consumers because they can be firmly sealed by simply folding when used and can be quickly opened when eaten. They are widely favored by merchants such as bakeries and snack shops. However, since the quick-fold seal parts of quick-fold seal packaging bags are all set on the back of the bag body, glue needs to be sprayed on the quick-fold seal parts in advance during production and then hot-sticking processing is performed. Hot-sticking processing requires heating and pressing the quick-fold seal parts, which leads to the problem of displacement and misalignment during laminating. During the heating and pressing process, the bag body will be damaged due to the difficulty in controlling the temperature, affecting the quality of the finished packaging bag. The existing equipment cannot adapt to the processing of packaging bags of different specifications, and different merchants have different requirements for the patterns of packaging bags. The patterns need to be printed separately, collected and stored, and then the quick-fold seal parts are separately laminating, resulting in low production efficiency and increased production costs.

[0039] During production, the large-sized packaging bags to be processed are placed on the large-sized conveyor belt 111, and the packaging bags are transported to the lifting platform 131 by the large-sized conveyor belt 111 in combination with the bag feeding guide plate 112, and stacked on the lifting platform 131. The lifting drive unit drives the lifting platform 131 to rise, allowing the conveying bag suction nozzle 132 to absorb the top layer of packaging bags, and the conveying drive unit controls the "L"-shaped conveying connecting rod 133 to convey the absorbed packaging bags to the straightening conveying printing mechanism 2. The packaging bag is fed into the straightening conveyor belt 21 through the conveying pressure wheel 24 and pressed under the straightening conveying bag pressing strip 23, and is transported to the bottom of the high-speed printing device 27 along the straightening guide plate 22, and is transported to the high-speed printing device 27 through the cooperation of the bag feeding pressure strip 26 and the printing conveyor belt 25.

[0040] After the positioning conveyor belt 55 transports the packaging bag to the strip pasting processing station, the strip suction driving unit drives the strip suction push rod 63 to push the strip pasting suction cup 62 to the strip taking port of the strip pasting storage tank 65, and the strip pasting suction cup 62 absorbs the strip from the strip taking port, and the strip pasting suction drum 61 rotates toward the reciprocating gluing device, and the absorbed strip pasting rotates to the bottom of the reciprocating gluing unit 66 and stops rotating, and the reciprocating gluing unit 66 applies the bonding agent on the bonding surface of the strip pasting through the gluing port, and the reciprocating gluing unit 66 is reset, and the strip pasting suction drum 61 continues to rotate until the strip pasting suction cup 62 vertically moves downward toward The packaging bag on the downward positioning conveyor belt 55 is driven by the strip pushing drive unit to drive the strip pushing rod 64 to push the strip suction cup 62 to move to the packaging bag bonding position, so that the strip with adhesive adsorbed by the strip suction cup 62 is attached to the back of the packaging bag, and the strip suction cup 62 releases the adsorption, and the positioning conveyor belt 55 continues to convey the packaging bag with the strip affixed to the strip pressing plate 67, and the strip pressing drive unit drives the strip pressing plate 67 to pressurize downward, and the strip is further firmly pressed and attached to the packaging bag with the cooperation of the strip gasket 68, thereby completing the strip bonding process.

[0041] The positioning conveyor belt 55 conveys the packaging bags that have completed the stripping from the bag outlet end to the stacking discharge conveyor belt 72, and they are neatly stacked and temporarily stored on the stacking discharge conveyor belt 72 through the stacking baffle plate 73. The cumulative number of packaging bags passing through the metering detector 71 is increased by one. When the cumulative number of stacked packaging bags reaches the preset stacking number, the stacking discharge conveyor belt 72 rotates and drives the stacked packaging bags to move to the next process through the stacking baffle plate 73 for processing in the next process.

[0042] Second embodiment:

[0043] This embodiment is similar to the first embodiment, and the difference lies in that, in this embodiment, when it is necessary to process small-sized packaging bags, the packaging bags are stacked and stored in the bag placing groove 122, and the packaging bags are pressed tightly in the bag placing groove 122 by the bag pressing plate 124, and then the lower bag rotating wheel 123 rotates to drive the packaging bags at the bottom layer to move toward the bag feeding outlet, and after being sent out from the bag feeding outlet, they are sent out between the bag feeding pressing wheel 125 and the bag feeding bottom plate 121 and fall onto the lifting platform 131, repeating the rapid processing of the printed strips in the first embodiment.
