Description

Technical Field

[0001] This utility model relates to the field of plastic packaging bag technology, specifically a bag-making machine that avoids loosening of plastic raw materials. Background Technology

[0002] A bag-making machine is a mechanical device specifically designed for producing various types of plastic bags, paper bags, or composite material bags. It processes raw materials (such as plastic film, paper, etc.) into bags through a series of automated or semi-automated processes. When using a bag-making machine, thermosetting plastics are generally used. These plastics undergo a chemical reaction upon heating, forming a permanently hardened substance that cannot be reheated and molded, making bag making convenient.

[0003] Patent CN215283643U discloses a bag-making machine for food packaging bags, including a bag-making machine, a composite device, and a heat insulation plate. The front side of the composite device is fixedly connected to the rear side of the bag-making machine. Insertion slots are provided on both the front and rear sides of the top of the bag-making machine. The front and rear sides of the bottom of the heat insulation plate are inserted into the insertion slots. A cavity is provided on the front side of the bag-making machine's interior, and a positioning mechanism is fixedly installed inside the cavity. A circular through hole is provided on the front side of the bag-making machine. This utility model, through the coordinated use of the bag-making machine, composite device, heat insulation plate, insertion slot, cavity, positioning mechanism, rotating rod, torsion spring, traction rope, positioning block, circular through hole, groove, fixing mechanism, fixing block, connecting block, pushing block, fixing groove, square through hole, and mating hole, solves the problem of poor heat insulation in existing products. This bag-making machine for food packaging bags has the advantage of good heat insulation.

[0004] Based on existing solutions and actual use, current bag-making machines still have some problems, such as: the raw materials are prone to loosening during the production process, which leads to insecure heat sealing or cold sealing and bag leakage. Furthermore, the loosening makes it difficult to maintain the consistency and integrity of the bag shape during the forming process. At the same time, the raw materials may become uneven during processing, resulting in ripples, wrinkles and other problems, which affect the overall appearance and quality of the bag. Utility Model Content

[0005] The purpose of this invention is to provide a bag-making machine that avoids loosening of plastic raw materials, thereby solving the problems mentioned in the background art, which are prone to loosening during the current bag-making process, resulting in insecure heat sealing or cold sealing, leakage, and difficulty in maintaining the consistency and integrity of the bag shape during the forming process. In addition, during the bag-making process, unevenness of the raw material surface during processing may cause problems such as ripples and wrinkles, thus affecting the overall appearance and quality of the bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bag-making machine that avoids loosening of plastic raw materials, comprising:

[0007] The control panel has a first mounting bracket fixedly installed on its top, and the first mounting bracket is arranged in a U-shape.

[0008] Also includes:

[0009] A sliding block is slidably connected to the side wall of the first mounting frame and is symmetrically arranged about the vertical central axis of the first mounting frame. A guide rod is rotatably connected to the block. A first rotating rod is rotatably connected to both the front and rear ends of the interior of the first mounting frame. A first bevel gear is fixedly installed at the lower end of the first rotating rod. A second rotating rod is rotatably connected to the lower end of the interior of the first mounting frame. A second bevel gear is fixedly installed at both the front and rear ends of the second rotating rod and meshes with the first bevel gear. A second mounting frame is fixedly installed at the left end of the top of the operating table and is symmetrically arranged about the vertical central axis of the first mounting frame. The height of the second mounting frame is less than the height of the first mounting frame. A movable box is fixedly installed at the left end of the top of the operating table and is symmetrically arranged about the vertical central axis of the operating table. A connecting block is slidably connected inside the movable box.

[0010] Preferably, the upper end of the first rotating rod is threaded, and the first rotating rod and the inner wall of the sliding block are threaded together, and the first rotating rod drives the guide rod through the sliding block to form a lifting structure.

[0011] Preferably, pressure rollers are rotatably connected to both the upper and lower ends of the second mounting frame, and the upper pressure roller in the second mounting frame is in a sliding state. A spring is fixedly installed at the upper end of the interior of the second mounting frame, and the lower end of the spring is connected to the upper end of the pressure roller.

[0012] Preferably, one end of the connecting block extends through to the outside of the mobile box, and an installation frame is fixedly installed on the block body. The frame of the installation frame is arranged in a "U" shape, and a detachable scraper is installed inside the groove of the installation frame.

[0013] Preferably, a tension spring is fixedly installed at the left end inside the mobile box, and the right end of the tension spring is fixedly connected to the left end of the connecting block.

[0014] Preferably, a guide groove is rotatably connected to the right end of the top of the mobile box, and a take-up roller is rotatably connected to the left side of the guide groove. A motor is fixedly installed on the side wall of the mobile box, and the output end of the motor is connected to the shaft of the take-up roller.

[0015] Preferably, a pull rope is fixedly installed at the right end of the connecting block, and the pull rope passes through the guide groove and is wound together with the take-up roller.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the bag making machine that avoids the loosening of plastic raw materials can avoid the loosening of raw materials during the bag making process by forming a drop, thereby stabilizing the state of the raw materials and helping to produce bags with consistent shapes. Furthermore, by adjusting the height, the tension of the raw materials can be effectively adjusted, so as to effectively control the stretching state of the raw materials and avoid quality problems caused by raw material fluctuations, thereby improving the quality of the product. At the same time, by smoothing, wrinkles and ripples that occur in the raw materials during the production process can be effectively removed, ensuring that the surface of the raw materials is flat, thereby improving the appearance quality of the finished products.

[0017] 1. The device is equipped with a first mounting frame, a sliding block, a guide roller, a second mounting frame, pressure rollers, and springs. Pressure rollers are installed at both the upper and lower ends of the second mounting frame. The upper pressure roller of the second mounting frame is also set in a sliding state, allowing the raw material to pass through the middle of the pressure roller. Since the spring inside the second mounting frame is fixedly connected to the pressure roller, the elastic force of the spring drives the upper pressure roller of the second mounting frame to come into contact with the lower pressure roller of the second mounting frame. Then, the raw material is placed on the surface of the guide roller, and the raw material is passed through the pressure rollers on the other set of the second mounting frame. Since the height of the second mounting frame is less than the height of the first mounting frame, a drop difference is formed between the pressure roller and the guide roller. This drop difference prevents the raw material from loosening during the bag making process, thereby stabilizing the state of the raw material and helping to produce bags with a consistent shape, thus improving the external quality of the product.

[0018] 2. The device comprises a first mounting frame, a sliding block, a guide roller, a first rotating rod, a first bevel gear, a second rotating rod, and a second bevel gear. The second bevel gear on the second rotating rod meshes with the first bevel gear on the first rotating rod, causing the first rotating rod inside the first mounting frame to rotate synchronously. The upper end of the first rotating rod is threaded, and the first rotating rod is threaded to the inner wall of the sliding block. The rotation of the first rotating rod causes the sliding block to slide on the first mounting frame, and the rotation of the first rotating rod, through the sliding block, drives the guide roller to form a lifting structure, thereby adjusting the height of the guide roller and thus adjusting the drop between the pressure roller and the guide roller. Adjusting the height effectively regulates the tension of the raw material, allowing for effective control of the material's stretching state and preventing quality problems caused by material fluctuations, thereby improving product quality.

[0019] 3. The system includes a movable box, a connecting block, a mounting frame, a scraper, a tension spring, a guide groove, a take-up roller, a motor, and a pull rope. The motor's output end is connected to the shaft of the take-up roller, causing the motor to drive the take-up roller to rotate. The pull rope is fixedly installed on the right end of the connecting block, passing through the guide groove and winding around the take-up roller. The connecting block is slidably connected inside the movable box, and the mounting frame is fixedly installed on the connecting block. The scraper is fixedly installed on the groove of the mounting frame. When the motor runs, the pull rope causes the connecting block to slide inside the movable box, and the mounting frame synchronously moves the scraper. The tension spring inside the movable box is fixedly connected to the connecting block. When the connecting block slides, it simultaneously stretches the tension spring, which in turn smooths the raw material by moving the scraper. When the motor stops, the spring force causes the scraper to reset, allowing the scraper to smooth the raw material again. This smoothing effectively removes wrinkles and ripples from the raw material during production, ensuring a smooth surface and improving the appearance quality of the finished product.

[0030] 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.

[0031] Please see Figure 1-9 This utility model provides a technical solution: a bag making machine that avoids loosening of plastic raw materials, comprising: an operating table 1, a first mounting frame 2, a sliding block 3, a guide roller 4, a first rotating rod 5, a first bevel gear 6, a second rotating rod 7, a second bevel gear 8, a second mounting frame 9, a pressure roller 10, a spring 11, a moving box 12, a connecting block 13, a mounting frame 14, a scraper 15, a tension spring 16, a guide groove 17, a take-up roller 18, a motor 19, and a pull rope 20.

[0032] First, as attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 6As shown, when the raw materials are made into bags by the bag-making machine, a first mounting frame 2 is fixedly installed on the top of the operating table 1, and a second mounting frame 9 is fixedly installed on the top of the operating table 1. The second mounting frame 9 is arranged symmetrically about the vertical central axis of the first mounting frame 2. Pressure rollers 10 are rotatably connected to both the upper and lower ends of the second mounting frame 9. The upper pressure roller 10 of the second mounting frame 9 is in a sliding state, and a spring 11 is fixedly installed on the upper part of the body of the second mounting frame 9. The lower end of the spring 11 is also connected to the pressure roller 10. The upper ends are connected together. First, pull the upper pressure roller 10 of the second mounting frame 9 on the left side of the operating table 1, so that the upper pressure roller 10 slides on the frame of the second mounting frame 9. At the same time, when the pressure roller 10 slides, it synchronously drives the spring 11 to compress, so that a gap is formed between the upper pressure roller 10 and the lower pressure roller 10 in the second mounting frame 9. Then, the raw material is placed in the middle of the pressure roller 10, and then the fixing of the upper pressure roller 10 is loosened, so that the upper pressure roller 10 is reset by the elastic force of the spring 11. The upper pressure roller 10 and the lower pressure roller 10 are tightly fitted together, thereby fixing the raw material through the pressure roller 10. After the raw material passes through the second mounting frame 9 on the right side of the operating table 1, the raw material is pulled. Since the first mounting frame 2 is set in a "U" shape, and both the front and rear ends of the first mounting frame 2 are slidably connected to sliding blocks 3, and the guide rods 4 are rotatably connected to the blocks 3, the raw material is stretched and placed on the surface of the guide rods 4, and the raw material is tightly fitted to the surface of the guide rods 4. Then the raw material is pulled again, so that it passes between the pressure rollers 10 on the second mounting frame 9 on the left side of the operating table 1. The elastic force of the spring 11 makes the pressure rollers 10 tightly fitted together, thereby fixing the raw material. Then, since the height of the two sets of second mounting frames 9 is smaller than the height of the first mounting frame 2, a drop is formed between the pressure rollers 10 and the guide rods 4. By placing the raw material in the middle of the pressure rollers 10 and on the guide rollers 4, the raw material is kept in a taut state, avoiding loosening during the bag making process.

[0033] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, the material drop is created by the pressure roller 10 and the guide roller 4, allowing for adjustment based on the actual relaxation. The second rotating rod 7 is rotatably connected inside the first mounting frame 2, and the first rotating rod 5 is rotatably connected to both ends of the first mounting frame 2. Second bevel gears 8 are fixedly mounted on both ends of the second rotating rod 7, and a first bevel gear 6 is fixedly mounted on the lower end of the first rotating rod 5. The first bevel gear 6 meshes with the second bevel gear 8. Rotating the second rotating rod 7 causes the second bevel gear 8 to mesh with the first bevel gear 8. The meshing between the wheels 6 can drive the first rotating rods 5 at both ends of the first mounting frame 2 to rotate synchronously. Since the upper end of the first rotating rod 5 is threaded and is also connected to the first rotating rod 5 through the inner wall of the sliding block 3, the rotation of the first rotating rod 5 can drive the sliding block 3 to slide on the frame of the first mounting frame 2. The sliding of the sliding block 3 can drive the guide rod 4 to rise and fall, thereby adjusting the height of the guide rod 4. Since the raw material is placed on the surface of the guide rod 4, the tension of the raw material can be adjusted by adjusting the height of the guide rod 4, and the stretching state of the raw material can be effectively controlled.

[0034] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 7 Appendix Figure 8 and attached Figure 9As shown, after the raw material is placed, it is pulled to be placed above the operating table 1, and thus below the scraper 15. A movable box 12 is fixedly installed on the left side of the top of the operating table 1, and the movable box 12 is symmetrically arranged about the vertical central axis of the operating table 1. A motor 19 is fixedly installed on the side wall of the movable box 12, and the output end of the motor 19 is connected to the shaft of the take-up roller 18. The operation of the motor 19 drives the rotation of the take-up roller 18. A connecting block 13 is slidably connected inside the movable box 12, and the connecting block 13 extends through to the outside of the movable box 12. A mounting frame 14 is fixedly installed on the block of the connecting block 13. The mounting frame 14 has a "U"-shaped structure, and a detachable scraper 15 is installed inside the groove of the mounting frame 14. A tension spring 16 is fixedly installed on the left side of the inside of the movable box 12, and the right end of the tension spring 16 is connected to the left end of the connecting block 13. A pull rope 20 is fixedly installed at the right end. Since the pull rope 20 passes through the movable box 12 and is connected to the guide groove 17, and is wound around the take-up roller 18, the pull rope 20 can be wound around its surface by the rotation of the take-up roller 18. When the pull rope 20 is wound around the surface of the take-up roller 18, it can be guided by the guide groove 17, causing the pull rope 20 to drive the connecting block 13 to slide inside the movable box 12. When the connecting block 13 slides inside the movable box 12, it is guided by the guide groove 17. The frame 14 drives the scraper 15 to move. While the scraper 15 is moving, the connecting block 13 drives the tension spring 16 to stretch. Thus, the movement of the scraper 15 can smooth the raw material on the surface of the operating table 1. At the same time, the controller can stop the two sets of motors 19, and the tension spring 16 will drive the connecting block 13 to reset. Then, the reset of the connecting block 13 can drive the scraper 15 to smooth the raw material again, which can effectively remove the wrinkles and ripples of the raw material during the production process and ensure that the surface of the raw material is flat.
