[0038] During the production of packaging bags, there's often a lack of effective transitions between one process and the next. This lack of smooth transitions leads to numerous intermediate steps in the production process, requiring manual intervention such as transferring bags and adjusting machine settings. This not only increases labor costs but also reduces production efficiency, making the entire manufacturing process less smooth.

[0039] The utility model provides a bag making machine.

[0040] See also Figure 1 and Figure 2 In one embodiment of the present invention, the bag making machine 100 includes:

[0041] Heat sealing machine 1, used for heat-pressing and sealing packaging bag 01;

[0042] The die-cutting machine 2 is provided on one side of the heat sealing machine 1 and is used to cut the packaging bag 01; and

[0043] The reversing mechanism 3 is disposed between the heat sealing machine 1 and the die-cutting machine 2 and is detachably connected to the heat sealing machine 1 . The reversing mechanism 3 is used to transport the packaging bag 01 from the heat sealing machine 1 to the die-cutting machine 2 .

[0044] In the technical solution of the present invention, the bag-making machine 100 achieves continuous automated operation from heat sealing to cutting by effectively combining a heat sealer 1, a die-cutter 2, and a reversing mechanism 3, significantly improving the production efficiency of the packaging bags 01 and ensuring the smoothness and consistency of the production process. The provision of the reversing mechanism 3 ensures that the packaging bags 01 are immediately transferred to the die-cutter 2 for cutting after being heat-sealed by the heat sealer 1, reducing the need for manual intervention in the intermediate links. Furthermore, the reversing mechanism 3 is detachably connected to the heat sealer 1, allowing it to be disassembled and installed in the desired location as needed, providing flexibility in equipment layout, facilitating adjustment of the production line layout according to production needs, and facilitating equipment maintenance and upgrades.

[0045] Specifically, there is no specific limitation on the structural structure of the reversing mechanism 3. For example, it can be a conveyor belt, and the two ends of the conveyor belt are respectively in contact with the working surface of the heat sealing machine 1 and the working surface of the die-cutting machine 2, so as to continuously transfer the packaging bags 01 and reduce the manual handling and transportation links. Of course, the reversing mechanism 3 can also use a robot gripper to transfer the packaging bags 01 between two adjacent processes to improve accuracy and processing efficiency. Optionally, position sensors can be installed at key positions on the heat sealing machine 1 and the die-cutting machine 2 to monitor the position and status of the packaging bags 01 and ensure a smooth transition. Furthermore, a visual inspection system, such as an industrial camera or other video equipment, can be provided between the heat sealing machine 1 and the die-cutting machine 2 to monitor the quality of the packaging bags 01 in real time, so as to automatically adjust the equipment to adapt to deviations.

[0046] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 , the reversing mechanism 3 includes:

[0047] A support assembly 31 is detachably connected to the heat sealing machine 1;

[0048] The first reversing roller 32 is provided on the side of the support assembly 31 away from the ground and abuts against the working surface of the heat sealing machine 1; and

[0049] The second reversing roller 33 is provided on the side of the support assembly 31 away from the ground and is spaced apart from the first reversing roller 32. The second reversing roller 33 is provided close to the die-cutting machine 2.

[0050] The packaging bag 01 is transferred from the heat sealing machine 1 to the working surface of the die-cutting machine 2 through the first reversing roller 32 and the second reversing roller 33 .

[0051] Specifically, by setting a first reversing roller 32 and a second reversing roller 33, the first reversing roller 32 is in contact with the working surface of the heat sealing machine 1, and the second reversing roller 33 is set close to the die-cutting machine 2, so that the heat-sealed packaging bag 01 can be smoothly transferred from the working surface of the heat sealing machine 1 to the working surface of the die-cutting machine 2, greatly reducing the conversion time and manual intervention between processes, and improving the continuity and efficiency of the production line. Through the guiding effect of the two reversing rollers, the packaging bag 01 can smoothly complete the transfer between different processes. It should be noted that the length of the two reversing rollers must be greater than the width of the packaging bag 01 to facilitate the support and fixation of the packaging bag 01. Since the support assembly 31 is detachably connected to the heat sealing machine 1, such as by threaded connection or clip connection, the reversing mechanism 3 can be disassembled and installed between other processes.

[0052] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The first and second reversing rollers 32, 33 are rotatably mounted on the support assembly 31. These rotatable reversing rollers better adapt to the movement of the packaging bag 01, reducing resistance to the transfer of the packaging bag 01 and preventing potential tearing or damage to the packaging bag 01 during transfer, thereby ensuring the integrity of the packaging bag 01. Furthermore, the rotating reversing rollers ensure smoother and more continuous transfer of the packaging bag 01 from one process step to another, reducing pauses and friction caused by material transfer and improving the fluidity of the production line.

[0053] In the embodiments of the present invention, please refer to Figures 1 to 3 , the support assembly 31 includes:

[0054] The bottom frame 311 is detachably connected to the frame of the heat sealing machine 1;

[0055] The first support rod 312 is fixedly connected to the base frame 311, and the first reversing roller 32 is provided on a side of the first support rod 312 away from the base frame 311; and

[0056] The second support rod 313 is spaced apart and disposed on one side of the first support rod 312 . One end of the second support rod 313 is disposed on the bottom frame 311 , and the other end of the second support rod 313 is provided with a second reversing roller 33 .

[0057] Specifically, the base frame 311 is detachably connected to the frame of the heat sealer 1, providing stable support for the entire reversing mechanism 3 and ensuring stable operation of the reversing rollers during the production process. The design of the first support rod 312 and the second support rod 313 increases the load-bearing capacity of the support assembly 31, enabling it to withstand greater loads and meet the needs of high-intensity continuous production. The first reversing roller 32 and the second reversing roller 33 are respectively fixed to specific positions on the first support rod 312 and the second support rod 313, which helps to accurately control the transfer path of the packaging bag 01 and improve the accuracy and consistency of material transfer. It should be noted that the length of the two support rods is not specifically limited in this embodiment. In actual needs, they can be adjusted according to the height of the work surface of the heat sealer 1 and the die-cutting machine 2. It can be understood that two first support rods 312 and two second support rods 313 are respectively arranged relative to each other, and the two first support rods 312 are used to support the two ends of the first reversing roller 32, and the two second support rods 313 are used to support the two ends of the second reversing roller 33.

[0058] In the embodiments of the present invention, please refer to Figure 4 The reversing mechanism 3 also includes a support roller 34, and the support assembly 31 also includes a third support rod 314. One end of the third support rod 314 is mounted on the base frame 311, and the other end of the third support rod 314 is mounted with the support roller 34. This allows the support roller 34 to accurately provide support at the desired location when the heat sealer 1 and the die-cutter 2 are located far apart. This optimizes the conveying path of the packaging bag 01 and ensures smooth material transfer from the heat sealer 1 to the die-cutter 2. Furthermore, the support roller 34 helps distribute pressure on the packaging bag 01 during conveyance, reducing wear between the material and the reversing roller, thereby extending the service life of the packaging bag 01. Optionally, the support roller 34 can be set at a height between the heights of the two reversing rollers, ensuring that the height of the packaging bag 01 continuously increases or decreases from the first reversing roller 32 to the support roller 34 to the second reversing roller 33, thereby improving the smoothness of the movement of the packaging bag 01.

[0059] In the embodiments of the present invention, please refer to Figure 4 The base frame 311 has a mounting portion 3111 extending toward the side away from the ground. The first support rod 312, the second support rod 313, and the third support rod 314 are all rotatably connected to the mounting portion 3111. In other words, the three support rods are gathered at the mounting portion 3111 and can rotate around the mounting portion 3111 within a certain angle range, allowing the positions of the two reversing rollers and the support roller 34 to be appropriately adjusted, thereby ensuring support for multiple parts of the packaging bag 01 and preventing the packaging bag 01 from bending or sag on the side facing the ground due to the large distance between the first reversing roller 32 and the second reversing roller 33.

[0060] In the embodiments of the present invention, please refer to Figure 4 The first support rod 312, the second support rod 313, and the third support rod 314 are all telescopic rods, each having a fixed section and a telescopic section. One end of the telescopic section telescopes within the fixed section. The ends of the telescopic sections of the three support rods, away from the fixed section, are respectively provided with a first reversing roller 32, a second reversing roller 33, and a support roller 34. Because the telescopic sections can be quickly extended and retracted into the fixed section, the overall length of the three support rods is adjustable, thereby changing the setting heights of the first reversing roller 32, the second reversing roller 33, and the support roller 34 to adjust the setting height of the packaging bag 01 according to the actual production process. For example, when the working surface height of the die-cutting machine 2 is lower than that of the heat sealing machine 1, the second support rod 313 can be set lower than the first support rod 312 to accommodate different bag-making machines 100.

[0061] In the embodiments of the present invention, please refer to Figure 4 The support roller 34 is rotatably mounted on the third support rod 314. The rotatable support roller 34 reduces resistance to the transfer of the packaging bag 01, allowing it to better conform to the movement of the packaging bag 01, reducing wear on the packaging bag 01 and extending the service life of the packaging bag 01. The rotatable support roller 34 helps precisely guide the packaging bag 01 along a predetermined path, improving the accuracy and guidance of material transportation.

[0062] In the embodiments of the present invention, please refer to Figure 1 The first reversing roller 32 and / or the second reversing roller 33 are provided with a stopper sleeve 30, which is slidably connected to the first reversing roller 32 or the second reversing roller 33. The stopper sleeve 30 accurately locates the position of the packaging bag 01 on the reversing roller, reducing production interruptions and quality issues caused by the shifting or tilting of the packaging bag 01, thereby improving production stability. Optionally, a stopper sleeve 30 is provided at each end of each reversing roller, for contacting the two sides of the packaging bag 01. Furthermore, the stopper sleeve 30 protrudes from the surface of the reversing roller to prevent the packaging bag 01 from shifting toward either end during transfer, causing pauses or delays in the conveying process.

[0063] In the embodiments of the present invention, please refer to Figure 3 and Figure 4The reversing mechanism 3 also includes a moving wheel 35, which is located on the side of the support assembly 31 facing the ground. The design of the moving wheel 35 allows the entire reversing mechanism 3 to be easily moved on the production line, thereby easily adjusting the layout of the production line. In addition, the moving wheel 35 is provided with a self-locking structure that can automatically lock after the device reaches the predetermined position, ensuring the stability and positioning accuracy of the reversing mechanism 3 during operation. It should be noted that in order to adapt to the design of the first support rod 312 and the second support rod 313, the base frame 311 is configured as a square, and four moving wheels 35 are provided, and multiple moving wheels 35 are respectively arranged at the four corners of the base frame 311.

[0064] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
