[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, this utility model provides a technical solution: a flat-push automatic packaging machine, comprising: a U-shaped equipment frame 1; a guide plate 6 fixedly connected to the middle of the equipment frame 1, a belt conveyor 17 installed at one end of the guide plate 6, and a placement platform 3 fixedly installed at the end of the guide plate 6 away from the conveyor 17, with an air blowing section at the bottom of the placement platform 3 for blowing open the bag opening; a conveying section placed at one end of the guide plate 6, including a conveying roller 20 and a squeezing roller 21 for conveying and separating the packaging bags; a sealing section placed above the guide plate 6, including a sealing pressure plate 7 with lifting and lowering and an electric heating groove 9 opened at the top of the guide plate 6, with an electric heating plate installed inside the electric heating groove 9, and a heat-conducting aluminum plate installed on the top of the electric heating plate; and a printer 11 placed above the conveyor 17, with a labeling section at one end of the printer for placing the label on the outside of the packaging bag.
[0016] It should be noted that in this embodiment, a PLC controller and corresponding control switch are provided, and the servo motors are all equipped with encoders. The rolled packaging bag is placed in the middle of the equipment frame 1, and one end is passed around the conveyor roller in the middle of the equipment frame 1 in an S-shape. Then it is placed between the second conveyor roller 20 and the extrusion roller 21. The extrusion roller 21 is adjusted to squeeze the packaging bag between the extrusion roller 21 and the extrusion conveyor roller 20. The second conveyor roller 20 and the extrusion roller 21 drive the packaging bag to be conveyed upward. The air blowing unit blows air to make the packaging bag contact the conveyor 17. The conveyor 17 transports the product forward. When the opening of the packaging bag is on top of the placement platform 3, the placement platform 3 blows air into the inside of the packaging bag to lift the bag opening. Then, the product is placed inside the packaging bag. The conveyor 17 and the second conveyor roller 20 continue to transport the packaging bag and then stop. With the help of the encoder, the controller controls the sealing plate 7 to cooperate with the electric heating tank 9. During this period, the second conveyor roller 20 and the extrusion roller 21 drive the packaging bag to move in the opposite direction, thereby pulling and separating the connection of the packaging bag. The labeling unit affixes the express delivery slip printed by the printer 11 to the packaging bag containing the product. When the sealing plate 7 returns to its original position, the conveyor 17 transports it to one end.
[0017] In one embodiment, the air blowing unit includes a blower 23 and an air blowing box 4. The height of the placement platform 3 is higher than the height of the guide plate 6. The air blowing box 4 is a box with an opening at one end. The air blowing box 4 is fixed to the bottom of the placement platform 3. The blower 23 is fixed to the inside of one side of the equipment rack 1. The blower 23 is connected to the air blowing box 4 through an air duct.
[0018] It should be noted that, in this embodiment, when the conveyor roller 20 and the extrusion roller 21 convey the packaging bag upwards, the controller controls the fan 23 to blow air through the air duct and the air blowing box 4 towards the placement platform 3, so that the packaging bag can adhere to the top of the placement platform 3. The conveyor 17 conveys the packaging bag forward through friction. When the opening of the packaging bag corresponds to the air blowing box 4, the air blowing box 4 blows air to lift the bag opening. In one embodiment, the second conveyor roller 20 and the extrusion roller 21 rotate in the middle of the equipment frame 1, and a servo motor 22 for driving the second conveyor roller 20 is fixedly connected to one side of the equipment frame 1.
[0019] It should be noted that in this embodiment, a slider slidably mounted on the equipment frame 1 is rotatably connected to the extrusion roller 21. A threaded rod is installed inside the equipment frame 1 to adjust the position of the slider, thereby adjusting the distance between the conveyor roller 20 and the extrusion roller 21, allowing the conveyor roller 20 and the extrusion roller 21 to convey packaging bags of different thicknesses. The servo motor 22 drives the conveyor roller 20 to rotate via a synchronous pulley and synchronous belt. The forward and reverse rotation of the conveyor roller 20 conveys and pulls the packaging bags.
[0020] In one embodiment, the conveying unit further includes two conveying rollers 19 with their rotating shafts in the middle of the equipment frame 1. A servo motor 12 for driving one of the conveying rollers 19 is installed in the middle of the equipment frame 1. A lifting frame is vertically slidably connected in the middle of the equipment frame 1, and two tension rollers 18 are rotatably connected between the lifting frames.
[0021] It should be noted that in this embodiment, a support for placing packaging bag rolls is also installed in the middle of the equipment frame 1. The packaging bag roll is placed in the middle of the support, and then its bottom contacts the two conveyor rollers 19. The free end of the packaging bag is passed around the outside of the conveyor roller above the support, then around the outside of the tension roller 18, and then around the outside of the two conveyor rollers above the tension roller 18. Then it passes through the middle of the conveyor roller 20 and the extrusion roller 21. When the servo motor 22 drives the conveyor roller 20 to rotate, the conveyor roller 19 drives the packaging bag roll. The packaging bag is tightened by the gravity of the tension roller 18. When the conveyor roller 20 drives the packaging bag to move downward to pull and separate, the tension roller 18 tightens and straightens the packaging bag under the action of gravity.
[0022] In one embodiment, a support beam 2 is fixedly connected to the top of the equipment frame 1, and a cylinder 8 is fixedly installed inside the equipment frame 1 at the position corresponding to the support beam 2. The output end of the cylinder 8 is fixedly connected to a sealing pressure plate 7. A duct connected to a fan 23 is installed on the support beam 2, and a nozzle facing the placement platform 3 is installed on the outside of the duct.
[0023] It should be noted that in this embodiment, when the cylinder 8 drives the sealing plate 7 downward, the electromagnetic reversing valve at the end of the fan controls the bottom nozzle of the support beam 2 to blow air downward, thereby flattening the end of the beam that needs to be welded. The sealing plate 7 presses the packaging bag tightly inside the electric heating tank 9 for heating and sealing. The packaging bag is then pulled apart by the reverse rotation of the conveyor roller 20.
[0024] In one embodiment, a mounting bracket 10 is fixedly connected to the middle of the equipment rack 1, a mounting frame 24 is fixedly connected to the top of the mounting bracket 10, and a printer 11 is fixedly connected to the top of the mounting frame 24.
[0025] It should be noted that in this embodiment, a barcode scanner 5 and a computer system are installed on one side of the top of the support beam 2. During operation, product information is entered through the barcode scanner 5 and then sent to the computer system. The corresponding data from the computer system is sent to the printer 11, and the printer 11 prints the product.
[0026] In one embodiment, the labeling unit includes a sliding plate 25 slidably connected to one side of the mounting bracket 24. A servo motor 27 is fixedly connected to one side of the mounting bracket 24. The output end of the servo motor 27 is fixedly connected to the sliding plate 25 via a rack assembly 26 for driving the sliding plate 25 to move laterally. A servo motor 13 is fixedly connected to one side of the sliding plate 25. A rack assembly 14 is installed on one side of the sliding plate 25. The rack assembly 14 includes a rack that is vertically slidably installed on the side of the sliding plate 25. A gear is meshed with the outer side of the rack. The output end of the servo motor 13 is fixedly connected to the gear. A negative pressure box 15 is installed at the bottom of the rack assembly 14. A fan 16 for upward exhaust is installed inside the negative pressure box 15.
[0027] It should be noted that in this embodiment, the rack assembly 26 includes a gear 2 fixed to the rack 2 and meshing with the top of the rack 2. The gear 2 is fixed to the output end of the servo motor 4 27. The servo motor 4 27 drives the rack 2 to move through the gear 2. The rack 2 drives the slide plate 25 to move laterally, thereby realizing the lateral movement of the negative pressure box 15. The servo motor 2 13 drives the rack to move vertically on the outside of the slide plate 25 through the gear, thereby driving the negative pressure box 15 to rise and fall through the servo motor 2 13. The fan 16 inside the negative pressure box 15 generates negative pressure by exhausting air to adsorb and fix the printed form. With the drive of the servo motor 2 13 and the servo motor 4 27, the rising and falling and lateral movement are realized, thereby attaching the form to the product bag below.
