[0092] Embodiment three:

[0093] like Figure 1-Figure 41As shown, the feeding mechanism 3 of the present invention is intended to optimize the feeding process of cardboard, reduce manual handling, and improve production efficiency. The feeding mechanism 3 is composed of three main parts: a lifting mechanism 15, a flattening mechanism 16, and a paper feeding mechanism 17. The core of the lifting mechanism 15 is the elevator 18, which is composed of structures such as a reducer and a motor. These components work together and are driven by a chain 20 to connect the lifting auxiliary platform 19 to achieve the up and down movement of the lifting auxiliary platform 19. The function of the reducer is to reduce the high-speed operation of the motor to meet the requirements of the elevator 18 for low speed and high torque, and to ensure the smoothness and precision of the lifting process. The motor provides power and transmits the power to the lifting auxiliary platform 19 through the chain 20 to complete the lifting operation. This design allows the stacked cardboard to be mechanically lifted to the position of the flattening mechanism 16, greatly reducing the workers' handling work. The flattening mechanism 16 is provided with a supporting paper board 21, on which a paper pressing slide bar 22 is fixedly installed, on which a paper pressing adjusting seat 23 is movably installed, and the paper pressing adjusting seat 23 can be adjusted in position according to different lengths of paper skins.

Through the cooperation of the paper pressing adjusting seat 23 and the flattening paper pressing seat 25, the flattening paper pressing wheel 26 can be moved on two axes, and the position of the flattening paper pressing wheel 26 can be adjusted according to different sizes of paper skins to ensure that the flattening paper pressing wheel 26 is pressed on the paper skin. The function of the flattening paper pressing wheel 26 is to further ensure that the paper skin is flat after being separated, so as to prepare for subsequent processing steps. The paper feeding mechanism 17 includes a paper feeding base 27, a first driving device 28, a paper feeding roller shaft 29 and a paper feeding paper pressing shaft 30.

The function of this pressing wheel is to keep the paper skin flat during transportation and prevent the paper skin from curling or shifting during high-speed transportation. Through mechanical structure and automatic control, the whole process of paper skin from stacking to flattening and transportation is automated, which greatly improves the efficiency of paper skin processing. The design of the elevator 18 and the lifting auxiliary platform 19 of the lifting mechanism 15 makes the transportation of paper skin easy and efficient.

The second driving device 32 is a power source, which drives the first pressing shaft 34 to rotate. The first pressing shaft 34 is fixedly installed with a first pressing wheel 37 through a tension adjustment bolt 36. During production, according to the production of different types of paper bags, the position of the first pressing wheel 37 is adjusted by the tension adjustment bolt 36 to make the pre-folding line position accurate, which is convenient for the subsequent folding and forming of the paper skin. The rubber-coated wheel 35 fixedly installed on the paper wheel shaft 33 has excellent wear resistance, impact resistance and anti-skid properties, and can maintain stable operation in harsh working environments. The function of the rubber-coated wheel 35 is to drive the paper skin to be transported forward, ensure that the paper skin does not slip during high-speed transportation, prevent the position of the paper skin from shifting, and improve production accuracy. Through automated operation, manual intervention is reduced, production costs are reduced, and product consistency and reliability are improved.
