[0001] This utility model relates to the field of bag making equipment technology, and in particular to a cutting and sewing bag making machine for environmentally friendly woven fabrics. Background Technology

[0002] With the increasing awareness of environmental protection, eco-friendly woven fabric, as a biodegradable and recyclable packaging material, has been widely used in various fields, such as shopping bags, logistics packaging, and agricultural coverings. The demand for eco-friendly woven fabric bags is also growing.

[0003] In traditional eco-friendly woven fabric bag making processes, cutting and sewing are usually two separate steps, resulting in long production cycles, low efficiency, and reliance on manual operation, leading to unstable production efficiency and affecting overall production efficiency. To solve these problems, this utility model provides an integrated cutting and sewing bag making machine for eco-friendly woven fabrics. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a one-stop bag-making machine for cutting and sewing environmentally friendly woven fabrics.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bag-making machine for cutting and sewing environmentally friendly woven fabrics includes a worktable. A mounting frame is fixedly connected to one side of the worktable. Two feed rollers are rotatably connected inside the mounting frame. Electric push rods are fixedly connected to both sides of the upper surface of the mounting frame. The telescopic ends of the two electric push rods are fixedly connected to the same hot cutting blade. A support frame is fixedly connected to one side of the upper surface of the worktable. A threaded screw is rotatably connected inside the support frame. A lifting platform is threaded onto the surface of the threaded screw. A discharge assembly is fixedly connected to one side of the lifting platform. A discharge plate is fixedly connected to the front of the worktable.

[0007] As a further improvement of this utility model, the discharge assembly includes a support rod fixedly connected to one side of the lifting platform. Mounting brackets are fixedly connected to both sides of the lower surface of the support rod. Discharge wheels are rotatably connected inside the two mounting brackets. A transmission rod is fixedly connected between the two discharge wheels. A small motor is fixedly connected to one side of one of the mounting brackets. The power end of the small motor is fixedly connected to the discharge wheel.

[0008] As a further improvement of this utility model, the lifting platform is provided with sliding grooves on both sides, and the support frame is fixedly connected with sliding rods that are compatible with the sliding grooves on both sides.

[0009] As a further improvement of this utility model, a lifting motor is fixedly connected to the upper end of the lifting platform, and the power end of the lifting motor is fixedly connected to a threaded screw.

[0010] As a further improvement of this utility model, a protective shell is fixedly connected to one side of the mounting frame, and a connecting gear is fixedly connected to one end of each of the two feeding rollers. The two connecting gears mesh, and both connecting gears are rotatably connected inside the protective shell.

[0011] As a further improvement of this utility model, a drive motor is fixedly connected to the other side of the mounting frame, the power end of the drive motor is fixedly connected to one of the feed rollers, and two support plates are fixedly connected to the lower surface of the worktable.

[0012] The beneficial effects of this utility model are:

[0013] By setting up feeding rollers, the two feeding rollers are driven by two meshing gears during use. During the conveying of the woven fabric, the two feeding rollers run in opposite directions, which can flatten the woven fabric and ensure the flatness and stability of the woven fabric during the cutting process. This avoids problems such as inaccurate cutting and weak sewing caused by wrinkles or unevenness of the woven fabric, thereby improving the quality of bag making.

[0014] By setting up a hot-cutting blade, during use, the electric push rod drives the hot-cutting blade to move downwards for cutting. The heat of the hot-cutting blade is uniform and stable. While cutting the woven fabric, the hot-cutting blade uses its own heat to sew the cut surfaces, resulting in a good sewing effect. This ensures the sealing and firmness of the bag, improves the overall quality of the product, and eliminates the two separate processes of cutting and sewing in traditional bag making, shortening production time, improving production efficiency, and enabling rapid and continuous production of environmentally friendly woven fabric bags.

[0015] By setting up the discharge component, when in use, the drive motor is started to drive the feed roller to convey the woven fabric, the electric push rod automatically controls the hot cutter to cut and sew, the lifting motor drives the lifting platform to move so that the discharge wheel contacts the woven fabric, and the small motor drives the discharge wheel to complete the discharge, reducing manual intervention, improving production efficiency and reducing labor costs. At the same time, the support frame has slide rods that are compatible with the slide groove fixedly connected to both sides, so that the lifting platform can maintain a stable movement trajectory during the lifting process.

[0016] In summary, this utility model has significant beneficial effects in terms of high-efficiency production, production quality, equipment stability and reliability, as well as ease of operation and safety, and can effectively meet the production needs of environmentally friendly woven fabric bags.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A bag-making machine for cutting and sewing environmentally friendly woven fabrics includes a workbench 1, a mounting frame 2 fixedly connected to one side of the workbench 1, two feed rollers 3 rotatably connected inside the mounting frame 2, electric push rods 4 fixedly connected to both sides of the upper surface of the mounting frame 2, the telescopic ends of the two electric push rods 4 fixedly connected to the same hot cutting blade 5, a support frame 6 fixedly connected to one side of the upper surface of the workbench 1, a threaded screw 7 rotatably connected inside the support frame 6, a lifting platform 8 threadedly sleeved on the surface of the threaded screw 7, a discharge assembly fixedly connected to one side of the lifting platform 8, and a discharge plate 9 fixedly connected to the front of the workbench 1.

[0023] In this utility model, the discharge assembly includes a support rod 10 fixedly connected to one side of the lifting platform 8. The support rod 10 serves to support and fix the mounting frame 11, ensuring that the mounting frame 11 can be stably installed on the lifting platform 8 and providing basic support for the installation of the discharge wheel 12. Mounting frames 11 are fixedly connected to both sides of the lower surface of the support rod 10. The two mounting frames 11 are symmetrically arranged, providing an installation position for the discharge wheel 12 and ensuring that the discharge wheel 12 can rotate stably. The discharge wheel 12 is rotatably connected inside both mounting frames 11. The surface of the discharge wheel 12 usually has a certain friction force, which can effectively drive the woven fabric to move and realize the discharge function. A transmission rod 13 is fixedly connected between the two discharge wheels 12. The function of the transmission rod 13 is to enable the two discharge wheels 12 to rotate synchronously, ensuring that the woven fabric is subjected to uniform force during the discharge process. A small motor 14 is fixedly connected to one side of one of the mounting frames 11. The power end of the small motor 14 is fixedly connected to the discharge wheel 12, and the small motor 14 provides power for the rotation of the discharge wheel 12.

[0024] Both sides of the lifting platform 8 are provided with sliding grooves. Both sides of the support frame 6 are fixedly connected with sliding rods 15 that are compatible with the sliding grooves. The sliding rods 15 guide and support the lifting platform 8 to prevent the lifting platform 8 from shaking or deviating during the lifting process. The upper end of the lifting platform 8 is fixedly connected with a lifting motor 16. The power end of the lifting motor 16 is fixedly connected to the threaded screw 7. The lifting motor 16 is the power source that drives the lifting platform 8 to lift. By controlling the operation of the lifting motor 16, the precise lifting of the lifting platform 8 can be achieved.

[0025] A protective shell 17 is fixedly connected to one side of the mounting frame 2. The protective shell 17 protects the internal connecting gears 18, preventing dust and debris from entering and affecting the gear transmission. It also prevents operators from contacting moving parts, improving safety. One end of each of the two feed rollers 3 is fixedly connected to a connecting gear 18. The two connecting gears 18 mesh, and the meshing transmission of the connecting gears 18 allows the two feed rollers 3 to rotate in opposite directions, thereby realizing the conveying and flattening of the woven fabric. Both connecting gears 18 are rotatably connected inside the protective shell 17. A drive motor 19 is fixedly connected to the other side of the mounting frame 2. The drive motor 19 provides power for the rotation of the feed rollers 3. By controlling the operation of the drive motor 19, the speed of the feed rollers 3 can be adjusted, thereby controlling the conveying speed of the woven fabric. The power end of the drive motor 19 is fixedly connected to one of the feed rollers 3. Two support plates 20 are fixedly connected to the lower surface of the worktable 1. The function of the support plates 20 is to support the entire worktable 1, so that it can be placed stably on the ground and ensure the normal operation of the equipment.

[0026] When using this invention, first align one end of the woven fabric on the raw material roller with the gap between the two feed rollers 3. Turn on the drive motor 19 and drive the two feed rollers 3 to rotate in opposite directions through two meshing connecting gears 18. Under the rotation of the feed rollers 3, the woven fabric is smoothly and orderly conveyed to the worktable 1. At the same time, the opposite rotation of the two feed rollers 3 can also have a good flattening effect on the woven fabric, ensuring that the woven fabric remains flat in the subsequent processing. After a suitable amount of woven fabric has accumulated on the worktable 1, turn off the drive motor 19 and start the electric push rod 4 to drive the hot cutter 5 to move slowly downward. The heat released by the hot cutter 5 can cut the woven fabric and sew the cut surface, realizing the integrated cutting and sewing operation.

[0027] Then, the lifting motor 16 is started to drive the threaded screw 7 to start rotating. The rotation of the threaded screw 7 drives the lifting platform 8 to move smoothly downward along the slide bar 15 until the two discharge wheels 12 below the support rod 10 just contact the cut woven fabric. The small motor 14 is turned on to transmit power to the two discharge wheels 12 through the transmission rod 13, so that the two discharge wheels 12 rotate synchronously. Under the joint action of the two discharge wheels 12, the woven fabric that has been cut on the worktable 1 is fed into the inclined discharge plate 9. Under the combined action of its own inertia and the tilt angle of the discharge plate 9, the woven fabric successfully completes the discharge process. Finally, the above operation is repeated to achieve efficient and continuous production of environmentally friendly woven fabric bags.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
