The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a packaging bag forming device. Figure 1-5 As shown, the packaging bag forming device includes: a base plate 1, on which a bracket 2 is fixedly mounted, and two material rollers 3 with plastic film wrapped thereon are provided on the bracket 2; a processing table 4 fixedly mounted on the top of the base plate 1, and a mounting frame 5 fixedly mounted on the top of the processing table 4; two U-shaped plates 6 fixedly mounted on the top of the base plate 1, and two rollers 7 are rotatably mounted on the two U-shaped plates 6; two motors 8 fixedly mounted on one of the U-shaped plates 6, and the output shafts of the two motors 8 are respectively fixedly connected to the rotating shafts of two of the rollers 7; a hot pressing mechanism for packaging bag forming installed on the mounting frame 5; and an alarm mechanism assembled on the bracket 2 for measuring the remaining amount of plastic film.

[0023] In this embodiment, the plastic film wound on the two material rollers 3 is a composite material, which is made of corresponding plastic materials and waterproof materials. The material ensures the waterproof performance and durability of the packaging bag. The plastic material itself has excellent corrosion resistance and can resist the erosion of various chemical substances, so that the packaging bag processed by the plastic film can maintain its stability in various environments. When the device is used to process the plastic film into a packaging bag, two motors 8 need to be started. The two motors 8 will drive the corresponding two rollers 7 to rotate at the same time. The rotation directions of the two rollers 7 need to be opposite, so that the plastic films on the two material rollers 3 can be pulled. Due to the clamping of multiple rollers 7, the two plastic films can be pulled. The films are tightly fitted together. Under the system setting of the device, the motor 8 will stop for a while at regular intervals. During this pause, the hot pressing mechanism will work once to perform heat-synthesize treatment on the two plastic films. These two heat-synthesized plastic films will become separate packaging bags after being cut in the subsequent process. During the forming process, the alarm mechanism will monitor the remaining amount of plastic film on the material roller 3. When the remaining amount of plastic film is low, the alarm mechanism will sound an alarm, so that the surrounding workers can come in time to replace the plastic film on the two material rollers 3. It is more convenient to use, and there will be no untimely replacement, which will not easily affect the processing efficiency of the packaging bags.

[0024] In a further preferred embodiment of the present invention, the hot pressing mechanism includes: a cylinder 9 fixedly mounted on the top inner wall of the mounting frame 5, a mounting plate 10 fixedly mounted on the output rod of the cylinder 9; a U-shaped heating plate 11 fixedly mounted on the bottom of the mounting plate 10; a plurality of support rods 12 welded to the top of the mounting plate 10; a plurality of connecting plates 13 respectively slidably mounted on the plurality of support rods 12, the tops of the plurality of connecting plates 13 are fixedly mounted with first springs 14, and the tops of the plurality of first springs 14 are respectively fixedly connected to the plurality of support rods 12; a plurality of pressure rods 15 slidably mounted on the mounting plate 10, the tops of the plurality of pressure rods 15 are respectively fixedly connected to the bottoms of the plurality of connecting plates 13, and the bottoms of the plurality of pressure rods 15 are rotatably mounted with rollers 16.

[0025] In this embodiment, the hot pressing mechanism is used for forming packaging bags. When working, the cylinder 9 is started, and the cylinder 9 will drive the mounting plate 10 to move downward. During the downward movement, the roller 16 will first contact the plastic film, and then as the mounting plate 10 continues to move downward, the roller 16 will push the pressure rod 15 to slide on the mounting plate 10, so that the connecting plate 13 fixed to the pressure rod 15 squeezes the first spring 14, thereby fixing the processing position of the plastic film, and then the U-shaped heating plate 11 at the bottom of the mounting plate 10 will perform thermal synthesis molding treatment on the two plastic films. After the treatment is completed, the cylinder 9 will drive the mounting plate 10 to reset. During the resetting process, the U-shaped heating plate 11 at the bottom of the mounting plate 10 will first separate from the plastic film, and then the roller 16 will leave the plastic film, so that the plastic film can be prevented from sticking to the bottom of the U-shaped heating plate 11, so that the molding work of the packaging bag can be carried out stably.

[0026] In a further preferred embodiment of the present utility model, the alarm mechanism includes: a plurality of slide bars 17 slidably mounted on the bracket 2, the bottom ends of the plurality of slide bars 17 are fixedly mounted with the same positioning plate 18, and a pressure roller is rotatably mounted on the positioning plate 18; a second spring 19 fixedly mounted on the top inner wall of the bracket 2, the bottom of the second spring 19 is fixedly connected to the top of the positioning plate 18; a top plate 20 welded to the top ends of the plurality of slide bars 17, an alarm is fixedly mounted on the top of the top plate 20; a first conductive copper sheet 21 fixedly mounted on the bottom of the top plate 20; a second conductive copper sheet 22 fixedly mounted on the top of the bracket 2, and the second conductive copper sheet 22 is located directly below the first conductive copper sheet 21.

[0027] In this embodiment, the alarm mechanism is used to measure the remaining amount of plastic film. During the measurement process, the plastic film on the material roller 3 will gradually decrease, so that the second spring 19 can elastically push the positioning plate 18 and the pressure roller downward, so that the pressure roller can continue to squeeze on the surface of the plastic film. The downward movement of the positioning plate 18 will drive the multiple slide bars 17 to move downward, and the multiple slide bars 17 will drive the top plate 20 to move downward. When the first conductive copper sheet 21 at the bottom of the top plate 20 contacts the second conductive copper sheet 22, the alarm will immediately sound an alarm, so that the surrounding workers can rush to replace the plastic film on the two material rollers 3 in time. It is more convenient to use and there will be no untimely replacement.

[0028] In a further preferred embodiment of the present invention, an electric telescopic rod 23 is fixedly mounted on one side of the bracket 2 , and a push block is fixedly mounted on the output rod of the electric telescopic rod 23 .

[0029] In this embodiment, the coordinated use of the electric telescopic rod 23 and the push block can facilitate manual work in pushing the top plate 20 to a suitable height when replacing the material roller 3. When in use, the electric telescopic rod 23 is started, and the electric telescopic rod 23 will drive the push block to push the top plate 20. The upward movement of the top plate 20 can make the pressure roller at the bottom of the positioning plate 18 separate from the material roller 3. After separation, the worker can replace the material roller 3. After the replacement is completed, the electric telescopic rod 23 is started to reset the push block, so that the pressure roller can be pressed on the material roller 3 again.

[0030] In a further preferred embodiment of the present invention, the plurality of support rods 12 are all configured to be U-shaped, and the plurality of the first springs 14 and the second springs 19 are all made of stainless steel.

[0031] In this embodiment, the plurality of first springs 14 and second springs 19 made of stainless steel have good corrosion resistance, are not easily corroded by moisture in the air, and have good durability.

[0032] In a further preferred embodiment of the present invention, the processing table 4 is configured to be rectangular, and an electric control box is fixedly installed on one side of the processing table 4.

[0033] In this embodiment, the electric control box can facilitate workers to set or operate the operation of the device.

[0034] In a further preferred embodiment of the present invention, a plurality of support blocks are fixedly mounted on the bottom of the base plate 1 , and anti-slip pads are fixedly mounted on the bottoms of the plurality of support blocks.

[0035] In this embodiment, the device can be stably placed on the ground for use by using multiple support blocks and multiple anti-slip pads.

[0036] To sum up, compared with the relevant technology, this solution can start two motors 8 to enable two rollers 7 to pull the plastic films on the two material rollers 3. Due to the clamping effect of multiple rollers 7, the two plastic films can be tightly fitted together. The two plastic films tightly fitted together can be heat-formed by the hot pressing mechanism, so that after the cutting process in the subsequent process, they can become individual packaging bags. The processed packaging bags are composite materials made of polymer materials and waterproof materials. The material ensures the waterproof performance and durability of the packaging bags. The polymer material itself has excellent corrosion resistance and can resist the erosion of various chemical substances, so that the packaging bags processed by the plastic film can maintain their stable performance in various environments. The alarm mechanism can automatically sound an alarm when the remaining amount of plastic film on the material roller 3 is low, so that surrounding workers can rush to replace the plastic films on the two material rollers 3 in time. It is more convenient to use, there will be no untimely replacement, and it is not easy to affect the processing efficiency of the packaging bags.
