[0017] 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.

[0018] Please see Figures 1-4 This utility model provides a woven bag sealing device, including a workbench 1 and a first bracket 4 fixedly connected to the top surface of the workbench 1 by bolts. An electric push rod 3 is installed on the surface of the first bracket 4. The output shaft of the electric push rod 3 is fixedly connected to a pressure plate 2. A heating wire is embedded inside the pressure plate 2. The heating wire is a resistance wire made of nickel-chromium alloy. A placement shell 5 is provided on the top surface of the workbench 1. Two positioning shells 8 are symmetrically fixedly connected to the bottom surface of the placement shell 5. A plurality of air pipes 7 are evenly arranged inside the placement shell 5, and the plurality of air pipes 7 are interconnected. A flexible hose 9 is fixedly connected to the surface of the air pipes 7. A dust collection box 10 is fixedly connected to the end of the flexible hose 9 away from the air pipe 7. An air suction pump 12 is installed on the surface of the dust collection box 10. The suction end of the air suction pump 12 is inserted into the dust collection box 10 through a connecting pipe. The top surface of the housing 5 is fixedly connected to a positioning plate 6 by bolts. The surface of the positioning plate 6 has several positioning holes, each corresponding to the suction port of the air pipe 7. Each positioning plate 6 has a filter screen inside, and the dust collection box 10 has a filter cloth 11 inside. The suction end of the suction pump 12 is located between the inner wall of the dust collection box 10 and the outer wall of the filter cloth 11. An activated carbon plate 13 is slidably connected inside the filter cloth 11. In order to prevent the woven bag from curling up before sealing, the woven bag is first placed on the surface of the positioning plate 6, and then the suction pump 12 is started to suck air into the dust collection box 10, thereby creating a negative pressure inside the dust collection box 10. Finally, the air pipe 7 will adsorb the woven bag onto the surface of the positioning plate 6 through the positioning holes, thus preventing the woven bag from curling up before sealing.

[0019] When the woven bag is heat-sealed, harmful fumes will be generated at the heat-sealing point. At this time, due to the continuous air intake of the air tube 7, the generated fumes will be drawn into the interior of the air tube 7 through the positioning hole, and finally enter the interior of the dust collection box 10 through the hose 9. Then, they will be adsorbed by the activated carbon plate 13, and the particles inside the fumes will be caught by the filter cloth 11. When cleaning is required, the filter cloth 11 can be pulled out from the interior of the dust collection box 10 to facilitate the centralized treatment of the particles inside the filter cloth 11.

[0020] In this embodiment, a motor 14 is installed on the bottom surface of the workbench 1. The output shaft of the motor 14 is fixedly connected to a lead screw 15 via a coupling. The end of the lead screw 15 away from the motor 14 is rotatably connected to the workbench 1 via a bearing. A connecting block 16 is threaded onto the surface of the lead screw 15. The connecting block 16 passes through the bottom surface of the workbench 1 and is fixedly connected to the placement shell 5. When the placement shell 5 needs to be moved, the motor 14 is connected to an external power source and started. The connecting block 16 will move the placement shell 5 on the top surface of the workbench 1 due to the rotation of the lead screw 15, thus moving the woven bag to the bottom of the pressure plate 2. Before sealing, the heating wire needs to be preheated by connecting to an external power source. Then, the electric push rod 3 is connected to an external power source and started. The pressure plate 2 will move downward, ultimately sealing the woven bag.

[0021] In this embodiment, a second support 17 is fixedly connected to the top surface of the workbench 1 by bolts. A slider 18 is slidably connected inside the second support 17. A pressure block 20 is fixedly connected to the bottom end of the slider 18. A screw 19 is threadedly connected inside the slider 18. The screw 19 is rotatably connected to the second support 17 via a bearing. A positioning frame 21 is slidably connected inside the second support 17. The positioning frame 21 and the slider 18 are fixedly connected. A linkage frame 22 is slidably connected inside the positioning frame 21. A pressure roller 23 is rotatably connected to the bottom end of the linkage frame 22. A spring 24 is wound around the surface of the linkage frame 22. The bottom end of the spring 24 is fixedly connected to the linkage frame 22, and the top end of the spring 24 is connected to... The positioning frames 21 fit together, and the bottom surface of the pressure roller 23 is lower than the bottom surface of the pressure block 20. When the woven bag is placed on the surface of the positioning plate 6, the screw 19 is rotated by turning the handwheel, and the slider 18 will drive the pressure block 20 to move downward. At the same time, the positioning frame 21 will move downward. Finally, while the pressure block 20 is squeezing the woven bag, the spring 24 will also be squeezed by the positioning frame 21, and the elastic potential energy will be used to make the pressure roller 23 stick tightly to the surface of the woven bag. Then, force is applied to the linkage frame 22, so that the linkage frame 22 slides inside the positioning frame 21, thereby driving the pressure roller 23 to roll on the surface of the woven bag, so as to roll the surface of the woven bag flat.

[0022] It should be noted that the electric push rod 3 and the air pump 12 are existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0023] The use of this utility model involves the following steps: S1: After the woven bag is placed on the surface of the positioning plate 6, the screw 19 is rotated by turning the handwheel. The slider 18 will drive the pressure block 20 to move downward. At the same time, the positioning frame 21 will move downward. Finally, while the pressure block 20 is squeezing the woven bag, the spring 24 will also be squeezed by the positioning frame 21. The spring 24 will use its elastic potential energy to make the pressure roller 23 stick to the surface of the woven bag. Then, force is applied to the linkage frame 22, causing the linkage frame 22 to slide inside the positioning frame 21, thereby driving the pressure roller 23 to roll on the surface of the woven bag, so as to roll the surface of the woven bag flat. S2: In order to prevent the woven bag from curling up before sealing, first place the woven bag on the surface of the positioning plate 6, then start the suction pump 12 to suck air into the dust collection box 10, thereby creating negative pressure inside the dust collection box 10. Finally, the air pipe 7 will adsorb the woven bag onto the surface of the positioning plate 6 through the positioning hole, thus preventing the woven bag from curling up before sealing. S3: When heat-sealing the woven bag, harmful fumes will be generated at the heat-sealing point. At this time, due to the continuous air intake of the air tube 7, the generated fumes will be drawn into the interior of the air tube 7 through the positioning hole, and finally enter the interior of the dust collection box 10 through the hose 9. Then, they will be adsorbed by the activated carbon plate 13, and the particles inside the fumes will be caught by the filter cloth 11. When cleaning is required, the filter cloth 11 can be pulled out from the interior of the dust collection box 10 to facilitate the centralized treatment of the particles inside the filter cloth 11. S4: When the placement shell 5 needs to be moved, connect the motor 14 to the external power supply and start it. The connecting block 16 will move the placement shell 5 on the top surface of the workbench 1 due to the rotation of the lead screw 15. This will move the woven bag to the bottom of the pressure plate 2. Before sealing, the heating wire needs to be preheated by connecting it to the external power supply. Then, connect the electric push rod 3 to the external power supply and start it. The pressure plate 2 will move downwards, finally sealing the woven bag.
