[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a plastic packaging bag forming machine. Background Technology

[0002] Plastic packaging bags are widely used in people's daily lives, from fresh produce packaging in farmers' markets to snack packaging in supermarkets, from household goods storage to temporary protection of industrial products—they are almost ubiquitous. Their production process is a complex, interconnected, and precisely coordinated system engineering project, typically involving multiple stages such as raw material transportation, heating and shaping, cooling and setting, cutting, and material collection. Each stage has its unique technological requirements and equipment support.

[0003] Existing plastic packaging bag forming machines have poor cooling and shaping effects, resulting in wrinkles or deformation of the bags; incomplete drying after cooling leaves residual moisture on the surface, affecting subsequent processing; and poor coordination between the cooling and drying processes reduces production efficiency.

The fixed frame has a cavity at its bottom end, and the cooling and shaping assembly is fixedly connected to the inner wall of the cavity. The cooling and shaping assembly includes a cooling box fixedly connected to the inner wall of the cavity. Two conveying pipes are fixedly connected to the top two ends of the cooling box, and the two conveying pipes are merged together. A water pump is fixedly connected to the water outlet end of the conveying pipe. A water sprayer is fixedly connected to the bottom of the water pump. An atomizing nozzle is fixedly connected to the inner top wall of the water sprayer. A blower A is fixedly connected to the inner side wall of the fixed frame.

[0022] The specific settings and functions of its cooling and shaping component 3 will be discussed below.

[0023] In this embodiment: the cooling and shaping component 3 includes a cooling box 31 fixedly connected to the inner wall of the cavity 2. The two ends of the top of the cooling box 31 are fixedly connected to the conveying pipes 32. The two conveying pipes 32 are combined together. The water outlet end of the conveying pipe 32 is fixedly connected to the water pump 33. The bottom of the water pump 33 is fixedly connected to the sprayer 34. The inner top wall of the sprayer 34 is fixedly connected to the atomizing nozzle 35. The inner side wall of the fixing frame 1 is fixedly connected to the A fan 36.

[0025] Please see Figure 1 Specifically, the conveyor frame 4 is located at both ends of the bottom wall of the fixed frame 1, and the inner wall of the conveyor frame 4 is rotatably connected to two conveyor rods 5.

[0026] The effect achieved by the above components is as follows: by setting the conveyor frame 4 to provide installation support for the conveyor rod 5, the rotation of the conveyor rod 5 drives the plastic packaging bag to move, so that it passes through the cooling and drying stages in sequence.

[0027] Please see Figure 2-3 Specifically, a plastic packaging bag slides through the gap between the two conveyor rods 5, and a guide plate 6 is fixedly connected to the inner bottom wall of the fixed frame 1.

[0028] The effects achieved by the above components are as follows: by setting the gap between the conveyor rods 5, the position of the plastic packaging bag is restricted, ensuring its smooth conveying; the guide plate 6 guides the excess liquid after cooling to a designated direction, preventing the liquid from flowing randomly.

[0029] Please see Figure 3 Specifically, a water channel 7 is provided on the surface of the guide plate 6, and a water collection channel 8 is provided at the middle of the bottom wall of the fixing frame 1 and the top of the cooling box 31.

[0034] The effect achieved by the above components is as follows: by setting the limiting cavity 11, the card box 38 is positioned and fixed, preventing the B fan 39 and the heating plate 310 from shifting during operation, thus ensuring a stable drying effect.

[0035] Please see Figure 5 Specifically, the drying oven 37 has a heat insulation layer 12 fixedly connected to the interlayer of the oven wall, and the inner bottom wall of the outlet end of the drying oven 37 is also fixedly connected to a conveyor frame 4 and a conveyor rod 5.

[0036] The above components achieve the following effects: by setting the heat insulation layer 12, heat loss in the drying oven 37 is reduced, and energy utilization is improved; the conveyor frame 4 and conveyor rod 5 at the outlet end transport the dried plastic packaging bags to the next process.

[0037] Working principle: A cooling and shaping component 3 is installed. Coolant is stored in a cooling box 31 and transported via a water pump 33 to a sprayer 34 through a delivery pipe 32. The atomizing nozzle 35 atomizes the coolant, evenly covering the surface of the plastic packaging bag, achieving rapid and uniform cooling and shaping, reducing wrinkles and deformation. Fan A 36 accelerates the evaporation of moisture from the packaging bag surface. Combined with the hot air generated by fan B 39 and the heating wire 311 of the heating plate 310 within the drying chamber 37, the packaging bag is thoroughly dried, preventing residual moisture from affecting subsequent processing. A card box 38 secures fan B 39 and the heating plate 310, ensuring stable drying. The conveyor frame 4 and... The conveyor rod 5 smoothly carries the packaging bag through the cooling and drying stages, achieving efficient connection between the two stages and improving production efficiency. The water channel 7 of the guide plate 6 guides excess coolant into the water collection tank 8. The water collection tank 8 at the top of the cooling box 31 enables coolant to be recycled and reused, saving resources. The filter screen 9 prevents impurities from contaminating the packaging bag. The observation window 10 facilitates real-time monitoring of the processing status. The limiting cavity 11 fixes the card box 38. The heat insulation layer 12 reduces heat loss from the drying box 37. The conveyor frame 4 and the conveyor rod 5 at the outlet end transport the formed packaging bag to the next process.
