Description

Technical Field

[0001] This utility model relates to the field of edge sealing structure technology, specifically to an edge sealing structure for a packaging bag making machine. Background Technology

[0002] Edge sealing makes packaging bags appear more upright and three-dimensional, with a sophisticated and high-end appearance. It can highlight the effect of graphic designs and trademarks, enhance the product's grade and quality, and thus strengthen consumers' aesthetic experience and trust in the brand. Edge sealing uses heat and pressure to tightly seal the opening of the packaging, preventing product leakage and contamination. Especially for industries such as food and pharmaceuticals that require high sealing and hygiene standards, edge sealing effectively ensures product quality and safety.

[0003] For example, the sealing structure of a packaging bag making machine disclosed in the authorization announcement number CN222495656U includes an operating table, a motor installed on one side of the top wall of the operating table, a positive and negative threaded screw installed at the output end of the motor, two movable plates threaded to one side of the surface wall of the positive and negative threaded screw, two support plates fastened to one side of the top wall of the operating table, a slide rod fastened to one side of the surface wall of the two support plates, the slide rod and the two movable plates being slidably connected, and the positive and negative threaded screw and the two support plates being rotatably connected.

[0004] Although it achieves the goal of preventing the film material from shifting during the sealing process, resulting in uneven sealing lines, leakage, and affecting the sealing performance and aesthetics of the packaging bag, thus increasing the production cost of the packaging bag, it drives the sealing knife to perform sealing operations. Through the action of springs and damping rods, it absorbs impact energy, protects the sealing knife from damage, and reduces the friction between the sealing knife and the machine.

[0005] However, this does not solve the problem that the existing sealing structure is generally not conducive to conveniently moving the position to seal packaging bags of different heights, nor is it convenient to heat-seal packaging bags of different thicknesses, thus affecting the convenience of the bag making machine's sealing structure in heat-sealing packaging bags of different thicknesses. Utility Model Content

[0006] The purpose of this utility model is to provide a sealing structure for a packaging bag making machine, so as to solve the problem mentioned in the background art that the sealing structure is not convenient to move to seal packaging bags of different heights, and is not convenient to heat seal packaging bags of different thicknesses, which affects the convenience of the sealing structure of the bag making machine to heat seal packaging bags of different thicknesses.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a packaging bag making machine, comprising a track and a moving plate. The moving plate is disposed outside the track, and a support frame is disposed outside the moving plate. L-shaped plates are symmetrically disposed outside the support frame. Slide rails are symmetrically installed on the sidewalls of the track, and a rack is installed on the sidewall of the track below a set of slide rails. A servo motor is installed at the top of the moving plate, and a rotating shaft is installed at the output end of the servo motor. The rotating shaft extends through the moving plate to its exterior, and a gear is installed at the end of the rotating shaft away from the servo motor. The rack meshes with the gear. The movable plate has four sets of sliders installed at its bottom, which are slidably connected to the slide rail. The side walls of the support frame are all provided with slide grooves. Stepper motors are symmetrically installed inside the support frame. Each stepper motor has a threaded rod installed at its output end. The threaded rods extend into the support frame and are movably connected to it. Threaded sleeves are fitted onto the surface of each threaded rod, and the threaded rods are threadedly connected to the threaded sleeves. Support plates are symmetrically installed on the side walls of each threaded sleeve, and the support plates are slidably connected to the slide grooves. A connecting plate is installed on the side of the threaded sleeve away from the support plate, and the threaded sleeves are all connected to the L-shaped plate through the connecting plate.

[0008] Preferably, guide plates are installed on the side walls of the L-shaped plate, and the guide plates extend to the outside of the L-shaped plate.

[0009] Preferably, each of the L-shaped plates has a guide wheel movably mounted on its top end, and a guide block is mounted on the side of the top end of each L-shaped plate near the guide wheel.

[0010] Preferably, a first limiting wheel is movably installed on the side of the top of the L-shaped plate away from the guide block, and a fixed heating plate is installed on the side of the top of one set of L-shaped plates away from the first limiting wheel, and a first cylinder is installed on the side of the top of the other set of L-shaped plates away from the first limiting wheel.

[0011] Preferably, each of the first cylinders is equipped with a movable heating plate at its output end, the first cylinder is fixedly connected to the movable heating plate, and the movable heating plate is in contact with the fixed heating plate.

[0012] Preferably, a fixed edge sealing knife is installed on the side of the top of the L-shaped plate away from the fixed heating plate, and a second cylinder is installed on the side of the top of the L-shaped plate away from the movable heating plate.

[0013] Preferably, a movable edge-sealing knife is installed at the output end of the second cylinder, and the second cylinder is fixedly connected to the movable edge-sealing knife.

[0014] Preferably, the movable edge-sealing knife is in contact with the fixed edge-sealing knife, and a second limiting wheel is movably installed on the top side wall of the L-shaped plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the sealing structure not only realizes the convenient movement of the sealing structure of the bag making machine to seal packaging bags of different heights, but also facilitates the heat sealing process of packaging bags of different thicknesses, thus improving the convenience of the sealing structure of the bag making machine to heat seal packaging bags of different thicknesses.

[0016] When in use, the sealing structure of the bag making machine places the bag on the surface of the moving plate. The servo motor drives the rotating shaft and gear to rotate. The gear drives the rotating shaft, servo motor, moving plate and bag to move left and right to the working area. The stepper motor drives the threaded rod to rotate. The threaded rod drives the threaded sleeve, connecting plate and L-shaped plate to move up and down to the upper surface of the bag for sealing. This facilitates convenient movement to seal bags of different heights, and improves the flexibility of the sealing structure of the bag making machine for sealing bags of different heights.

[0017] When sealing packaging bags of different thicknesses is required, the packaging bag is placed on the surface of the moving plate. The servo motor drives the rotating shaft and gears to rotate. The gears drive the rotating shaft, servo motor, moving plate, and packaging bag to move left and right between two sets of guide plates. Guided by the two sets of guide plates, the upper surface of the packaging bag enters the interior of the L-shaped plate through guide wheels and guide blocks. Under the limitation of the first limit wheel, it moves to the surface of the fixed heating plate. The first cylinder drives the moving heating plate to move, so that the moving heating plate pushes the packaging bag towards the fixed heating plate for sealing. When heated, the moving heating plate opens in the reverse direction, allowing the packaging to continue moving to the surface of the fixed sealing knife. The second cylinder drives the moving sealing knife to move, pushing the packaging bag towards the fixed sealing knife for sealing. The second cylinder then opens in the reverse direction, allowing the packaging bag to be discharged through the second limit wheel. This facilitates convenient heating and sealing of packaging bags of different thicknesses, improving the ease of use of the bag making machine's sealing structure for heating and sealing packaging bags of varying thicknesses.
