[0002] Packaging bags refer to bags used to package various supplies, making it convenient to transport and store goods during the production and circulation process. Packaging bag making machines are automated equipment used to produce various plastic packaging bags. This machine is able to process plastic film and transform it into packaging bags of customized size and shape through a series of steps such as heating, forming, edge sealing and cutting. Packaging bag making machines are widely used in many industries such as food, medicine, daily necessities, and electronic products to meet the packaging needs of different commodities. The edge sealing structure of the packaging bag making machine is a key part to ensure the sealing and strength of the packaging bag. The edge sealing process usually involves heating elements and pressure application to melt the edges of the plastic film, and then press them together during the cooling process to form a firm seal.

[0003] However, the edge sealing structure of the existing packaging bag making machine is prone to uneven sealing and insufficient strength when sealing the packaging bags. The reason is that during the process of sealing the packaging bags, the user lacks a device to limit the position. Relying on the user's naked eye judgment, the packaging bag cannot always be in the center position, which easily leads to uneven edge sealing, waste, and reduced production efficiency of the packaging bags. Therefore, it is necessary to propose a new edge sealing structure for the packaging bag making machine. Utility Model Content

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example 1

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a sealing edge structure of a packaging bag making machine, comprising an operating table 1, a motor 2 is installed on one side of the top wall of the operating table 1, a positive and negative threaded screw rod 6 is installed on the output end of the motor 2, two movable plates 4 are threadedly connected to one side of the surface wall of the positive and negative threaded screw rod 6, two support plates 3 are fastened to one side of the top wall of the operating table 1, a sliding rod 5 is fastened to one side of the surface wall of the two support plates 3, the sliding rod 5 and the two movable plates 4 are slidably connected, the positive and negative threaded screw rod 6 and the two support plates 3 are rotatably connected, a first sliding groove 8 is opened on one side of the top wall of the operating table 1, the first sliding groove 8 and the two movable plates 4 are slidably connected, an extension plate 7 is fastened to one side of the surface wall of the two movable plates 4, and a limiting plate 19 is fastened to one side of the top wall of the operating table 1.

[0023] In this embodiment, the user starts the motor 2 installed on the operating table 1. Under the action of the motor 2, the output end of the motor 2 rotates to drive the forward and reverse threaded screw 6 to rotate. The two support plates 3 support the forward and reverse threaded screw 6 and the slide bar 5. Under the action of the first slide groove 8, the forward and reverse threaded screw 6 rotates to drive the movable plate 4 to move on the first slide groove 8. The slide bar 5 balances the movable plate 4 and moves synchronously. By limiting the centering of the packaging bag that needs to be sealed under the action of the extension plate 7, the film material is prevented from shifting during the sealing process, resulting in uneven sealing lines and leaking, affecting the sealing performance and aesthetics of the packaging bag, and increasing the production cost of the packaging bag. At the same time, under the action of the limiting plate 19, the farthest sealing distance of the packaging bag is limited to avoid the sealing position being too forward, thereby reducing the available space of the packaging bag. Example 2

[0024] like Figure 1-Figure 4 As shown, one side of the top wall of the operating table 1 is fastened with an edge banding base 18, one side of the top wall of the operating table 1 is fastened with a bracket 9, one side of the top wall of the bracket 9 is installed with a cylinder 10, the output end of the cylinder 10 is fastened with a first slide 11, one side of the surface wall of the first slide 11 is installed with two damping rods 13, one side of the bottom wall of the two damping rods 13 is fastened with a second slide 20, one side of the surface wall of the two damping rods 13 is installed with a spring 12, two second slide grooves 14 are provided on the inner wall of the bracket 9, the two second slide grooves 14 are slidably connected to the first slide 11, the two second slide grooves 14 are slidably connected to the second slide 20, one side of the surface wall of the second slide 20 is installed with a photoelectric sensor 15, one side of the bottom wall of the second slide 20 is fastened with an edge banding knife 17, and one side of the surface wall of the edge banding knife 17 is installed with a heating plate 16.

[0025] In this embodiment, after the photoelectric sensor 15 detects that the packaging bag has reached the edge sealing position (the model of the photoelectric sensor is Optex D2SA-MPS-M8), the cylinder 10 installed on the bracket 9 is started through the control system. Under the action of the second slide groove 14, the output end of the cylinder 10 moves to drive the first slide 11 to move on the second slide groove 14. The movement of the first slide groove 11 drives the damping rod 13 to move. The movement of the damping rod 13 drives the second slide groove 14 to descend. Then, the heating plate 16 installed on one side of the edge banding knife 17 is started. The edge banding knife 17 is heated under the action of the heating plate 16, and the edge banding knife 17 is lowered to perform edge banding on the packaging bag. By providing a heat sealing platform under the action of the edge banding base 18, it is easy to maintain and clean. By absorbing impact energy under the action of the spring 12 and the damping rod 13, the edge banding knife 17 is protected from damage and the friction between the edge banding knife 17 and the machine is reduced.

[0026] The working principle of this embodiment is as follows: when in use, first connect the power supply, and the user starts the motor 2. The output end of the motor 2 rotates to drive the forward and reverse threaded screw 6 to rotate. The two support plates 3 support the forward and reverse threaded screw 6 and the slide bar 5. The forward and reverse threaded screw 6 rotates to drive the movable plate 4 to move on the first slide groove 8. The slide bar 5 balances and moves the movable plate 4 synchronously. The centering of the packaging bag that needs to be sealed is limited by the extension plate 7, thereby avoiding the film material from shifting during the sealing process. Then, under the action of the limit plate 19, the farthest sealing distance of the packaging bag is limited. Then, the photoelectric sensor 15 detects the bag. After the bagging reaches the edge sealing position, the cylinder 10 is started through the control system, and the output end of the cylinder 10 moves to drive the first slide 11 to move on the second slide 14. The movement of the first slide 11 drives the damping rod 13 to move, and the movement of the damping rod 13 drives the second slide 20 to descend on the second slide 14. Finally, the heating plate 16 is started, and the edge sealing knife 17 is heated under the action of the heating plate 16. The edge sealing knife 17 is lowered to seal the packaging bag. A heat sealing platform is provided under the action of the edge sealing base 18, and the impact energy is absorbed under the action of the spring 12 and the damping rod 13, thereby protecting the edge sealing knife 17 from damage and reducing the friction between the edge sealing knife 17 and the machine.
