Description

Technical Field

[0001] This utility model relates to the technical field of food packaging bag processing equipment, specifically a bag making machine for food packaging bags. Background Technology

[0002] Food packaging bag making machines are an important part of the packaging machinery industry, widely used in food, pharmaceuticals, daily chemicals and other fields. The development history of food packaging bag making machines reflects the progress of packaging technology and the changes in the demand for food packaging. From early semi-automatic equipment to modern fully intelligent high-speed production lines, bag making machines are constantly innovating to meet the food industry's demand for efficient, precise and environmentally friendly packaging.

[0003] Patent document CN115520613A discloses a food packaging bag sealing machine, relating to the field of food packaging bag production technology. It includes a sealing equipment platform, a conveyor platform, a sealing chamber, a control panel, and a sealing device. The sealing equipment platform has a conveyor platform on top, and a sealing chamber is fixedly installed at one end of the top of the conveyor platform. This allows a rotating gear to drive a rotating block, causing an extension baffle to fold and rotate at a 90-degree angle. This facilitates the transport of the packaging bag to the processing area for sealing, solving the problem of packaging bags moving too fast and missing parts at the adjustment mechanism, preventing the sealing device from sealing. It also allows for the addition of a limit and deceleration function, making it easier to adjust the packaging bag.

[0004] Currently available food packaging bag making machines often produce wrinkles on the surface of the bags before sealing, affecting the final quality. Furthermore, when the food packaging bag material tilts during movement, the machine usually needs to be stopped and the material manually corrected, resulting in poor performance. Additionally, the size of the bags varies depending on the production order, requiring manual adjustment of the sealing device's output position, which is very time-consuming. Therefore, a new food packaging bag making machine has been designed to solve these problems. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a bag-making machine for food packaging bags to solve the technical problem of low efficiency of traditional devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bag-making machine for food packaging bags, comprising a main body, wherein two sets of first guide shafts are rotatably connected inside the main body, and two sets of main shafts are rotatably connected inside the main body behind the first guide shafts, wherein several extension arms are connected to both ends of each main shaft, and a leveling shaft that cooperates with the corresponding first guide shaft is connected between every two opposing extension arms, wherein the middle diameter of the leveling shaft is larger than the diameters at both ends, and two sets of second guide shafts that cooperate with the leveling shaft are installed inside the main body.

[0007] By adopting the above technical solution, the two sets of first guide shafts in the main body play a preliminary guiding role for the food packaging bag material. The leveling shaft connected to the extension arms at both ends of the main shaft cooperates with the first guide shaft, and the diameter of the middle of the leveling shaft is larger than that at both ends. When the material passes through the leveling shaft, this special shape design can apply different pressures to the material, stretching the material to both sides, thereby effectively eliminating wrinkles on the surface of the material and improving the quality of the packaging bag. The two sets of second guide shafts cooperate with the leveling shaft to further guide and stabilize the material, ensuring the smooth progress of subsequent processes.

[0008] The present invention is further configured such that two sets of mutually cooperating integrated shafts are rotatably connected inside the main body behind the second guide shaft, a sealing device is installed inside the main body behind the integrated shaft, and an output shaft is rotatably connected inside the main body behind the sealing device.

[0009] By adopting the above technical solution, the integrated shafts work together to further integrate and align the leveled material, making the material more regular and preparing it for the subsequent sealing process. The sealing device is used to seal the material, turning it into a complete packaging bag. The output shaft is responsible for outputting the sealed packaging bag from the bag making machine. The entire bag making process forms a complete system, ensuring the continuity and efficiency of the bag making process.

[0010] The present invention is further configured such that two sets of interleaved rolling wheels are rotatably connected inside the main body between the integrating shaft and the sealing device.

[0011] By adopting the above technical solution, the staggered rollers roll the material between the integrating shaft and the sealing device, further compacting the material, making it flatter, reducing the voids and unevenness inside the material, improving the quality and effect of sealing, and also helping to eliminate any possible residual micro-wrinkles.

[0012] The present invention is further configured such that the upper and lower ends of the main body are rotatably connected to rotating shafts between the grinding wheel and the sealing device, and a telescopic shaft is slidably connected between every two opposing rotating shafts, and a limit wheel is provided at both ends of each telescopic shaft.

[0013] By adopting the above technical solution, the length of the telescopic shaft on the rotating shaft is adjusted according to the width of the material, so that the limiting wheels on both sides of the telescopic shaft contact the edge of the material. When the food packaging bag material tilts during movement, the limiting wheels can limit and correct the material, bringing it back to the correct position without stopping the machine for manual correction, thus improving the efficiency of the bag making machine.

[0014] The present invention is further configured such that multiple sets of heat sealing blocks are slidably connected inside the sealing device, and a diamond-shaped telescopic bracket is rotatably connected between the top ends of all the heat sealing blocks. Each heat sealing block cooperates with each other through the diamond-shaped telescopic bracket. An adjusting shaft is rotatably connected inside the main body, and the adjusting shaft threaded through the two sets of heat sealing blocks located at the outermost ends.

[0015] By adopting the above technical solution, multiple sets of heat-sealing blocks in the sealing device cooperate with each other through diamond-shaped telescopic brackets. When it is necessary to adjust the size of the packaging bag according to different production orders, the adjustment shaft is rotated to make the heat-sealing blocks on both sides drive the diamond-shaped telescopic brackets, thereby adjusting the position of all heat-sealing blocks simultaneously, realizing the rapid adjustment of the sealing position. There is no need to manually adjust each heat-sealing block individually, saving a lot of time.

[0016] The present invention is further configured such that a cooling device is installed inside the main body, and the output end of the cooling device is located between the sealing device and the output shaft.

[0017] By adopting the above technical solution, after the packaging bag is sealed, the cooling device can cool the sealed area in time, making the seal more secure and stable, and reducing the natural cooling time of the sealed area, thereby improving the overall sealing efficiency.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention utilizes a drum-shaped leveling shaft to laterally stretch the material during roller pressing, thereby eliminating initial wrinkles. Then, the length of the telescopic shaft is adjusted according to the material's width, ensuring that the limiting wheels on both sides of the shaft contact the material's edge. When the food packaging bag material tilts during movement, the limiting wheels can stop and correct the material, returning it to the correct position without requiring manual correction by stopping the machine. When the size of the packaging bag needs to be adjusted according to different production orders, the position of all heat-sealing blocks is simultaneously adjusted by manipulating the adjusting shaft, achieving rapid adjustment of the sealing position without the need for individual manual adjustment of each heat-sealing block, saving significant time.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A bag-making machine for food packaging bags, such as Figure 1-5 As shown, the device includes a main body 1. Two sets of first guide shafts 2 are rotatably connected inside the main body 1. Two sets of main shafts 3 are rotatably connected behind the first guide shafts 2 inside the main body 1. Each main shaft 3 has several extension arms connected to both ends. A leveling shaft 4, which cooperates with the corresponding first guide shaft 2, is connected between every two opposing extension arms. The middle diameter of the leveling shaft 4 is larger than the diameters at both ends. Two sets of second guide shafts 5, which cooperate with the leveling shafts 4, are installed inside the main body 1. The two sets of first guide shafts 2 inside the main body 1 provide initial guidance for the food packaging bag material. The leveling shafts 4 connected to the extension arms at both ends of the main shafts 3 cooperate with the first guide shafts 2, and the middle diameter of the leveling shafts 4 is larger than the diameters at both ends. When the material passes through the leveling shafts 4, this special shape design can apply different pressures to the material, stretching it to both sides, thereby effectively eliminating wrinkles on the material surface and improving the quality of the packaging bag. The two sets of second guide shafts 5, in cooperation with the leveling shafts 4, further guide and stabilize the material, ensuring the smooth progress of subsequent processes.

[0029] Inside the main body 1, two sets of cooperating integrated shafts 6 are rotatably connected behind the second guide shaft 5. A sealing device 11 is installed inside the main body 1 behind the integrated shafts 6, and an output shaft 16 is rotatably connected inside the main body 1 behind the sealing device 11. The integrated shafts 6 cooperate to further integrate and align the leveled material, making the material more regular and preparing it for the subsequent sealing process. The sealing device 11 is used to seal the material, turning it into a complete packaging bag. The output shaft 16 is responsible for outputting the sealed packaging bag from the bag making machine. The entire bag making process forms a complete system, ensuring the continuity and efficiency of the bag making process.

[0030] Inside the main body 1, between the integrating shaft 6 and the sealing device 11, there are two sets of staggered rolling wheels 10. The staggered rolling wheels 10 roll the material between the integrating shaft 6 and the sealing device 11, further compacting the material, making the material flatter, reducing the gaps and unevenness inside the material, improving the quality and effect of sealing, and also helping to eliminate any possible residual micro-wrinkles.

[0031] The main body 1 has rotating shafts 7 rotatably connected at both the upper and lower ends of the body, between the grinding wheel 10 and the sealing device 11. A telescopic shaft 9 is slidably connected between every two opposing rotating shafts 7. Each telescopic shaft 9 has a limit wheel 8 at both ends. The length of the telescopic shaft 9 on the rotating shaft 7 is adjusted according to the width of the material so that the limit wheels 8 on both sides of the telescopic shaft 9 contact the edge of the material. When the food packaging bag material tilts during movement, the limit wheels 8 can limit and correct the material, returning it to the correct position without stopping the machine for manual correction, thus improving the efficiency of the bag making machine.

[0032] The sealing device 11 has multiple sets of heat-sealing blocks 12 slidably connected inside, and the tops of all heat-sealing blocks 12 are rotatably connected to a diamond-shaped telescopic bracket 13. Each heat-sealing block 12 cooperates with each other through the diamond-shaped telescopic bracket 13. The main body 1 has an adjusting shaft 14 rotatably connected inside, and the adjusting shaft 14 is threaded through the two sets of heat-sealing blocks 12 located at the outermost end. The multiple sets of heat-sealing blocks 12 in the sealing device 11 cooperate with each other through the diamond-shaped telescopic bracket 13. When it is necessary to adjust the size of the packaging bag according to different production orders, the adjusting shaft 14 is rotated to make the heat-sealing blocks 12 on both sides drive the diamond-shaped telescopic bracket 13, so that the position of all heat-sealing blocks 12 can be adjusted simultaneously, realizing the rapid adjustment of the sealing position. There is no need to manually adjust each heat-sealing block 12 individually, saving a lot of time.

[0033] The main body 1 is equipped with a cooling device 15, and the output end of the cooling device 15 is located between the sealing device 11 and the output shaft 16. After the packaging bag is sealed, the cooling device 15 can cool the sealing part in time, making the seal more secure and stable, and reducing the natural cooling time of the sealing part, thereby improving the overall sealing efficiency.

[0034] Working Principle: The two sets of first guide shafts 2 within the main body 1 provide initial guidance for the food packaging bag material. The leveling shafts 4, connected to the extension arms at both ends of the main shaft 3, cooperate with the first guide shafts 2. The diameter of the leveling shaft 4 in the middle is larger than at both ends. This special shape design applies different pressures to the material as it passes through the leveling shaft 4, stretching it to both sides, effectively eliminating wrinkles on the material surface and improving the quality of the packaging bag. The two sets of second guide shafts 5 cooperate with the leveling shaft 4 to further guide and stabilize the material, ensuring the smooth progress of subsequent processes. Then, the integrating shafts 6 cooperate to further integrate and align the leveled material, making it more regular and preparing it for the subsequent sealing process. In addition, the staggered rollers 10 crush the material between the integrating shaft 6 and the sealing device 11, further compacting the material, making it flatter, reducing internal voids and unevenness, improving the quality and effect of the sealing, and also helping to eliminate any remaining micro-wrinkles. During this process, the length of the telescopic shaft 9 on the rotating shaft 7 is adjusted according to the width of the material, allowing the limiting wheels on both sides of the telescopic shaft 9 to... The limit wheel 8 contacts the edge of the material. When the food packaging bag material tilts during movement, the limit wheel 8 can limit and correct the material, returning it to the correct position without stopping the machine for manual correction, thus improving the efficiency of the bag making machine. The sealing device 11 is used to seal the material, turning it into a complete packaging bag. The output shaft 16 is responsible for outputting the sealed packaging bag from the bag making machine. The entire bag making process forms a complete system, ensuring the continuity and efficiency of the bag making process. Finally, the sealing device 11 seals the material, turning it into a complete packaging bag. During this process, when it is necessary to adjust the size of the packaging bag according to different production orders, the adjusting shaft 14 is rotated, causing the heat sealing blocks 12 on both sides to drive the diamond telescopic bracket 13, thereby synchronously adjusting the position of all heat sealing blocks 12 and realizing rapid adjustment of the sealing position. There is no need to manually adjust each heat sealing block 12 individually, saving a lot of time. After the packaging bag is sealed, the cooling device 15 can cool the sealed part in time. Finally, the sealed packaging bag is output through the output shaft 16.
