Description

Technical Field

[0001] This utility model relates to the field of packaging bag production equipment technology, and in particular to a packaging bag blown film device. Background Technology

[0002] A blown film machine heats and melts plastic particles and then blows them into a film. Using brand-new particles results in fresh material. Dry polyethylene particles are added to the hopper and enter the screw by their own weight. They are then gradually melted due to external heating of the barrel. The molten plastic is filtered through the die head to remove impurities and comes out of the die head. After being cooled by air circulation, inflated, and passed through the herringbone plate, traction rollers, and wound up, the finished film is rolled into a tube. After the packaging bag is finished, advertisements are printed on its surface.

[0003] However, existing packaging bag blow molding equipment requires printing advertisements after processing. When printing advertisements on the rolled film, the film is too tough to be clamped and fixed, which causes wrinkles to appear on the film during the printing process, resulting in the offset of the printed advertisement position and affecting the overall effect of the product. In view of this, a packaging bag blow molding device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing packaging bag blow molding devices. After the packaging bag is processed, advertisements need to be printed on it. However, when printing advertisements on the rolled film, the film is too tough to be clamped and fixed. This causes wrinkles to appear on the film during the printing process, resulting in the offset of the printed advertisement position and affecting the overall effect of the product. Therefore, this invention proposes a packaging bag blow molding device.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A blown film device for packaging bags includes a worktable and support legs, wherein smoothing components are provided on the upper surface of the worktable near both sides;

[0007] The smoothing component includes a support column, which is fixedly connected to the worktable. The support column has a lifting groove inside, and a sliding column is slidably connected inside the lifting groove. A pressing block is fixedly connected to the inner side of the sliding column. The pressing block has a rotating cavity inside, and a pulling groove is formed through the rotating cavity near the bottom of both ends. A first transmission belt is rotatably connected inside the pulling groove.

[0008] Preferably, a connecting column is rotatably provided inside the rotating cavity, and driven columns are fixedly connected to both ends of the first transmission belt. A rotating groove is provided on the outer wall of the driven column near the center of the drive motor. Two second transmission belts are rotatably connected to the outer wall of the connecting column, and the other end of the second transmission belt is rotatably connected inside the rotating groove.

[0009] Preferably, a drive motor is fixedly connected to the upper surface of the pressing block near the center, and a drive gear is fixedly connected to the output end of the drive motor through the pressing block. A wedge gear meshes with the outer edge of the drive gear near one side, and a connecting column is fixedly connected to one end of the wedge gear.

[0010] Preferably, a flat plate is fixedly connected to the bottom of the pressing block near the center, and the bottom of the flat plate is at the same level as the bottom of the first transmission belt.

[0011] Preferably, an elastic element is fixedly connected to the upper end of the inside of the lifting groove, and a pressing plate is fixedly connected to the other end of the elastic element, with the bottom of the pressing plate abutting against the sliding column.

[0012] Preferably, a take-up roller is rotatably connected to one side of the worktable near the edge, and a reverse roller is provided inside the worktable near the take-up roller. Multiple holes are opened on the outer wall of the reverse roller, and a heating column is fixedly connected inside the reverse roller.

[0014] Preferably, the workbench is provided with two symmetrical lifting devices on its side, and the lifting end of the lifting device is fixedly provided with a printing device.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The drive motor rotates, causing the drive gear to drive the second transmission belt to rotate. At the same time, the driven column rotates. The first transmission belt on the outer wall of the driven column pulls the film to both sides, keeping the film taut and ensuring the integrity of the advertisement printing. It also reduces damage to the molecular chains on the film surface and improves the overall effect of the product.

[0017] 2. The printing film is heated and dried by the heating column inside the reverse roller, which can quickly dry and cure the printing pigments or inks, allowing them to adhere better to the film and enhance the adhesion and wear resistance of the advertisement. Attached Figure Description
