Description

Technical Field

[0001] This utility model relates to the field of elastic inner bags, specifically a simple elastic inner bag making device. Background Technology

[0002] With its advantages of anti-expansion, strong load-bearing capacity, and easy stacking, the reinforced inner bag has become a core packaging carrier in many fields. It is widely used for titanium dioxide, paint powder, fertilizers and seeds, cement additives, flour and grains, etc. Its built-in PE / PP ribs (flat wires or mesh sheets) can effectively distribute the pressure of materials and solve the problems of ordinary plastic bags taking up a lot of space, easy to tip over when stacked, and easy to break under load. It is especially suitable for the industrial packaging needs of powder and granular materials. However, existing bag-making equipment suffers from three major drawbacks that restrict production: First, manual reinforcement placement and step-by-step heat melting result in low efficiency, making the finished product prone to cracking under load. Second, automated equipment is difficult to debug, struggles to adapt to different thicknesses of reinforcement strips, and is prone to breakage or detachment. Third, it has weak anti-deviation capabilities, relying solely on fixed guide rollers for positioning, which cannot guide and direct the bag film, leading to uneven weight distribution in the finished product. Fourth, it lacks flexibility in reinforcement placement, with fixed mechanism positions requiring mold changes for adjustments, making it impossible to achieve multi-position reinforcement placement on a single bag and failing to meet customized needs. Furthermore, current bag-making equipment cannot clean debris from the surface of the bag film, which can easily lead to issues with the cleanliness of the bag production process and the quality of the finished product. Therefore, it is necessary to design a simple rebar inner bag making device to solve the above problems. Utility Model Content

[0016] Example 1 Please refer to Figure 1-4 As shown, this utility model provides a simple bag-making device for reinforcing inner bags, including a frame 1 of the bag-making device. A support plate 2 for placing bag film and reinforcing strips is welded to one end of the frame 1. An inlet is installed on the top of the support plate 2. A fixing frame 3 is installed on the top of the frame 1. A cleaning component for cleaning debris from the surface of the bag film is installed on one side of the fixing frame 3. A hot-melt component for bag-making operation is installed between the fixing frame 3 and the frame 1. A conveyor belt 4 is installed on the other side of the frame 1.

[0017] In addition, the support plate 2 at one end of the frame 1 can pre-support the bag film and the reinforcing strip. The inlet component guides and conveys the bag film and the reinforcing strip. Then, the cleaning component can clean the debris on the surface of the bag film. Then, the hot-melt component heat-melts and presses the two layers of bag film and the middle reinforcing strip together and drives them to move. The conveyor belt 4 is used to transport the finished product after the hot-melt processing for subsequent processing operations. The guide roller 27 on the outside of the support rod 26 can press down and limit the finished product after processing to prevent deviation or tilting, thereby improving the efficiency and practicality of the equipment in producing and processing reinforcing inner bags.

[0018] Specifically, the guide component includes a fixed shaft 5 that passes through one end of the frame 1. A rotating roller 6 for limiting the installation of the reinforcing bar is fitted on the outside of the fixed shaft 5. A plurality of evenly arranged first grooves 7 are formed on the outer surface of the rotating roller 6. A rotating shaft 8 is installed on one side of the frame 1 and on the side of the rotating roller 6. A first motor 9 is installed on one side of the frame 1 and at one end of the rotating shaft 8. An guide roller 10 is installed on the outside of the rotating shaft 8. A plurality of evenly arranged second grooves 11 are formed on the outside of the guide roller 10.

[0019] The fixed shaft 5 supports the rotating roller 6. The first groove 7 on the outer side of the rotating roller 6 corresponds one-to-one with the second groove 11 on the outer side of the guide roller 10. Multiple first grooves 7 can accommodate various sizes of rib arrangement and placement. The first motor 9 drives the guide roller 10 to rotate through the rotating shaft 8. The guide roller 10 can press down and guide the bag film and ribs. The two layers of bag film deform under the pressure of the guide roller 10 to limit the ribs, and the guide roller 10 conducts and transports the bag film.

[0020] More specifically, the cleaning component includes a support frame 12 installed on one side of the fixed frame 3. A first cylinder 13 is installed on the top of the support frame 12. A sliding frame 15 is installed at the bottom of the first cylinder 13 via a first push rod 14. A cleaning brush 16 is installed at the bottom of the sliding frame 15. Fixed rods 24 are installed on the inner side of the fixed frame 3 and on both sides of the cleaning brush 16. Guide rollers 25 are fitted on the outer side of the fixed rods 24.

[0021] In addition, the support frame 12 can support the first cylinder 13, the first cylinder 13 can drive the sliding frame 15 to move up and down through the first push rod 14, the cleaning brush 16 installed at the bottom of the sliding frame 15 can sweep and clean the debris on the surface of the bag film, the fixing rods 24 on both sides of the cleaning brush 16 can support and fix the guide roller 25, and the guide roller 25 on the outside of the fixing rod 24 can press down and guide the bag film to prevent the bag film from tilting or shifting.

[0022] Furthermore, the hot melt component includes two second cylinders 17 mounted on the top of the fixed frame 3. The second cylinders 17 are fixedly mounted with a mounting frame 19 via a second push rod 18. Pressure rollers 21 are mounted on the inner side of the mounting frame 19 and the bottom of the fixed frame 3 via a support shaft 20. A second motor 22 is mounted on the bottom of the fixed frame 3 at one end of the support shaft 20. A heating grid plate 23 is mounted on the inner side of the fixed frame 3 via bolts. A guide rod 28 is fixedly mounted on the top of the mounting frame 19 via bolts. The guide rod 28 passes through the fixed frame 3 and is slidably connected to it.

[0023] Among them, the guide rod 28 can guide and limit the mounting frame 19 to prevent the mounting frame 19 from shifting or shaking. The pressure roller 21 at the bottom of the mounting frame 19 can move closer to or further away from another pressure roller 21. The heating mesh plate 23 in the fixed frame 3 can preheat the bag film and the ribs. The two pressure rollers 21 are close to the bag film and the ribs to squeeze and convey them, thereby improving the bag making speed.

[0024] Working principle: First, place the bag film under the rotating roller 6, then place the reinforcing strip in the first groove 7 under the rotating roller 6, and then place the upper bag film on the guide roller. Then start the first motor 9 and the second motor 22. The first motor 9 drives the guide roller 10 to rotate through the rotating shaft 8. The guide roller 10 can press down and guide the bag film and the reinforcing strip. The two layers of bag film are deformed by the pressure of the guide roller 10, which limits the reinforcing strip. The second motor 22 drives the pressure roller 21 to rotate through the support shaft 20. Then, the two second cylinders 17 drive the mounting frame 19 to move downward through the second push rod 18. At the same time, the heating mesh plate 23 preheats and heats the bag film and the reinforcing strip. The two pressure rollers 21 press the bag film and the reinforcing strip. Finally, the finished product is transported by the conveyor belt 4.
