[0002] A bag making machine is a widely used device in the packaging industry, which is used to process film materials into various specifications of packaging bags. With the development of automation technology, modern bag making machines have the ability of high efficiency and continuous production, and can simultaneously process multiple rolls, that is, the unwinding device of the bag making machine is provided with multiple unwinding stations of different heights in the height direction, and multiple layers of film materials are simultaneously supplied to the main machine of the bag making machine to adapt to the needs of large-scale production. However, in actual operation, since the roll is usually heavy, manual carrying of the roll to the unwinding station of the bag making machine not only has high labor intensity, but also has low efficiency, especially in the production scene where the roll needs to be replaced to the unwinding station of different heights, and this problem is particularly prominent. In addition, manual operation may also have safety hazards, affecting the overall stability and safety of the production line. Therefore, it is necessary to solve the above technical problems.

[0029] Please refer to​​Figure 1 , Figure 2 and Figure 3 The automatic feeding mechanism for a bag-making machine provided in this application embodiment will now be described. This automatic feeding mechanism includes a frame 101, a linear guide 102, a sliding seat 103, a drive assembly, and a lifting arm 108. Wherein:

[0030] The linear guide 102 is vertically mounted on the frame 101; the sliding seat 103 is slidably connected to the linear guide 102; the drive assembly includes a servo motor 104 mounted on the frame 101 and a drive wheel 105 that is driven and horizontally connected to the servo motor 104; it also includes a driven wheel 106 that is rotatably mounted on the frame 101 and axially parallel to the drive wheel 105; and a synchronous belt 107 connected to the drive wheel 105 and the driven wheel 106. The drive wheel 105 and the driven wheel 106 are spaced apart along the extension direction of the linear guide 102. The sliding seat 103 is connected to the synchronous belt 107 and can be driven by the synchronous belt 107 to slide relative to the linear guide 102; the lifting arm 108 is connected to the sliding seat 103 and is used to support the target material roll.

[0031] According to the structure provided in this embodiment, the automatic feeding mechanism of the bag making machine provided in this embodiment is installed at the front end of the unwinding device of the bag making machine. In this way, the servo motor 104 can drive the synchronous belt 107 to rotate through the cooperation of the active wheel 105 and the passive wheel 106. Since the sliding seat 103 connected to the lifting arm 108 is connected to the synchronous belt 107 and slidably connected to the linear rail 102, and since the linear rail 102 is vertically installed on the frame 101, the synchronous belt 107 can also rotate forward or backward with the servo motor 104 during the forward and reverse rotation. In this way, the sliding seat 103 connected to the synchronous belt 107 can rise and fall along the linear rail 102 under the control of the servo motor 104 and automatically stop at the target position. When a material roll is placed on the lifting arm 108, the material roll can be automatically lifted to the predetermined position and aligned with the corresponding unwinding station. Then, the material roll can be easily pushed horizontally along the guide surface at the upper end of the lifting arm 108 to the corresponding unwinding station. The positioning is accurate and the feeding is easy and convenient. Therefore, the automatic feeding mechanism for the bag making machine provided in this embodiment can effectively improve the feeding efficiency of the bag making machine, which is far superior to the existing technology.

According to the above structure provided in the embodiment, the two groups of material feeding arms 108 can act on the same target material roll shaft by correspondingly arranging two groups of driving wheels 105, driven wheels 106, synchronous belts 107, sliding seats 103, wire rails 102 and material feeding arms 108, so that the feeding stability of the automatic feeding mechanism of the bag making machine in the embodiment can be effectively improved.

[0033] In another embodiment of the present application, please refer to Figure 1 、 Figure 2 and Figure 3 Each wire rail 102 comprises at least two wire rails 102 and is distributed on both sides of the sliding seat 103 in the horizontal direction.
