Technical Field
[0001] This utility model relates to the field of woven bag production technology, specifically to a woven bag sealing mechanism for processing. Background Technology
[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. They are typically made from polyethylene, polypropylene, and other chemical plastic raw materials. Widely used in maritime and transportation packaging of industrial and agricultural products, woven bags are also widely used in agricultural product packaging, including for aquatic products, poultry feed, and as covering materials for farms, as well as for shading, wind protection, and hail protection in crop cultivation. The market demand for woven bags has great potential, and its development prospects are very broad.
[0003] When plastic woven bags are being processed and conveyed, their unstable placement can cause them to shift, affecting subsequent edge sealing. Furthermore, after the edge sealing equipment used in the production and processing of plastic woven bags has sealed one side, it is often necessary to rearrange the bags and seal them again to achieve double-sided sealing, thus extending the production time.
[0004] Therefore, it is necessary to invent a woven bag sealing mechanism for processing to solve the above problems. Utility Model Content

A pressing motor is fixedly connected to both the support frame two and the side of the limiting plate away from the moving plate, and the output end of the pressing motor is fixedly connected to the roller. Starting the movable motor and the pressing motor drives the threaded rod and the roller to rotate.
[0009] Preferably, two sets of connecting rods are fixedly connected to the inner side wall of the workbench, a conveying mechanism is installed on the inner side wall of the workbench, and a wrinkle-removing roller is rotatably connected to the outer side wall of the connecting rod. The wrinkle-removing roller presses the woven bag to prevent wrinkles from forming.
[0010] Preferably, the de-wrinkling roller is provided with an inlet pipe and an outlet pipe inside. The inlet pipe and the outlet pipe are both fixedly connected to the right side of the workbench.

Roller rollers 207 are rotatably connected to both the limiting plate 208 and the inner sidewall of the support frame 205. The rotation of the threaded rod 204 moves the limiting plate 208, thus limiting the width of the woven bag while adjusting the distance between the two sets of roller rollers 207. The support frame 205 and the limiting plate 208... On opposite sides of 08, heating sleeves 206 are fixedly connected. The top of the roller 207 is located inside the heating sleeves 206. The heating sleeves 206 heat the roller 207 to achieve heat sealing. On the side of the support frame 205 away from the moving plate 202, a movable motor 3 is fixedly connected, and the output end of the movable motor 3 is fixedly connected to the threaded rod 204. On the sides of the support frame 205 and the limiting plate 208 away from the moving plate 202, pressing motors 4 are fixedly connected, and the output end of the pressing motor 4 is fixedly connected to the roller 207.

Through the cooperation of the worktable 1 and the double-sided sealing mechanism 2, the movable motor 3 is started to drive the threaded rod 204 to rotate. The threaded rod 204 drives the movable plate 202 and the limiting plate 208 to move, thereby limiting the woven bags of different widths. The distance between the two sets of heating sleeves 206 and the roller 207 is adjusted by the movement of the limiting plate 208, so that it can adapt to woven bags of different widths. The pressing motor 4 drives the roller 207 to rotate to achieve double-sided sealing, thereby improving work efficiency.
[0025] Refer to the instruction manual appendix Figure 1-5Two sets of connecting rods 11 are fixedly connected to the inner side wall of the workbench 1.

[0026] The working principle of this practical application is as follows:
[0027] Refer to the instruction manual appendix Figure 1-5 When sealing woven bags of different widths, the woven bags are first placed on the surface of the conveying mechanism 5, and then the movable motor 3 is started to drive the threaded rod 204 to rotate. The threaded rod 204 drives the movable plate 202 and the limiting plate 208 to move, thereby limiting the woven bags of different widths. The distance between the two sets of electric heating sleeves 206 and the roller 207 is adjusted by the movement of the limiting plate 208. The electric heating sleeves 206 heat the roller 207 so that it can heat seal the woven bags, thus adapting to woven bags of different widths. The pressing motor 4 drives the roller 207 to rotate to achieve double-sided sealing, thereby improving work efficiency. During rotation, the coolant inside the wrinkle-removing roller 10 is introduced and discharged through the cooperation of the water inlet pipe 7 and the water outlet pipe 8. The circulation pump 9 circulates the water inlet pipe 7 and the water outlet pipe 8, thereby using the wrinkle-removing roller 10 to cool the woven bags and prevent wrinkles from forming.
