[0014] (3) Beneficial effects
[0015] The utility model provides a folding mechanism for producing paper bags, which has the following beneficial effects:
[0016] (1) Motor 1 starts, which drives the rotating rod to start rotating. The rotating rod 1 is connected to the folding plate through the connecting block, so that the folding plate starts to flip. The design of the soft pad ensures that the folded items are protected during the folding process to avoid damage or scratches. At the same time as the folding plate flips, motor 2 is also started. It is located on the mounting plate and drives the pressure bar to rotate through the rotating rod 2. The action of the pressure bar ensures that the folding plate and the pressure bar fit tightly together during the folding process to complete the accurate folding action. The function of the hydraulic rod is to adjust the position of the upper pressure plate. The pressure of the upper pressure plate stabilizes the position of the folded items and ensures the accuracy and stability of the folding. Through precise coordination and automated operation, the efficiency and accuracy of the folding operation are greatly improved. It is suitable for production environments that require a large number of folding operations and solves the problems of errors and low efficiency in manual operations.
[0017] (2) The paper bag is transported to the bottom of the bracket by the conveyor belt and then stops. The electric push rod 1 starts, which pushes the limit block to move along the positioning rod. The movement of the limit block is transmitted to the suction cup on the electric push rod 2 through the connecting plate. The suction cup is activated and starts to move downward and locates to the predetermined position of the paper bag. The air pump is started and the air pump extracts the air inside the suction cup through the exhaust pipe to form a vacuum suction. The suction cup uses this vacuum suction to firmly grasp the paper bag to ensure a stable grasping process. The electric push rod 1 continues to operate and drives the grasped material paper bag to the required position for subsequent processing or assembly. The action of the electric push rod 2 can adjust the height and position of the suction cup to ensure accurate grasping and placement. The entire system improves the efficiency and reliability of the production line through precise mechanical coordination and automated operation, and solves the problems of errors and inefficiency that may be introduced by manual operation.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0024] See also Figure 1-4 , the utility model provides a technical solution:
[0025] Embodiment 1: A folding mechanism for producing paper bags, comprising a workbench 1, a conveyor belt 2 being provided on the outside of the workbench 1, a pair of fixed plates 3 being fixedly connected to the top of the workbench 1, and a folding mechanism being provided on the top of the workbench 1, the folding mechanism comprising a folding plate 7, a pressure strip 14 and a hydraulic rod 25, an outer wall of the fixed plate 3 on one side being fixedly connected to a motor 1 4, an output end of the motor 1 4 being fixedly connected to a rotating rod 1 5, and an outer wall of the rotating rod 1 5 being fixedly connected to a pair of connecting blocks 6, a folding plate 7 being fixedly connected to the outer wall of the connecting block 6, and a soft pad 8 being provided on the outer wall of the folding plate 7, a motor 2 11 being fixedly connected to the top of the workbench 1, The output end of motor 2 11 is fixedly connected to rotating rod 2 13, and at the same time, a pair of mounting plates 12 are fixedly connected to the top of the workbench 1, and rotating rod 2 13 is rotatably connected in the mounting plate 12, and at the same time, the pressure strip 14 is fixedly connected to the outer wall of rotating rod 2 13, and the output end of the hydraulic rod 25 is fixedly connected to the upper pressure plate 26. An inner groove 10 is provided on the top of the workbench 1, the folding plate 7 is rotatably connected between the fixed plates 3 on both sides, and the pressure strip 14 is rotatably connected between the fixed plates 3 on both sides, a pair of positioning blocks 9 are fixedly connected to the top of the workbench 1, and the positioning blocks 9 are located on both sides of the pressure strip 14, and at the same time, the size of the upper pressure plate 26 is smaller than the distance between the pressure strips 14 on both sides.
[0026] Starting the hydraulic rod 25 causes the upper pressure plate 26 to move downward, firmly positioning the paper bag. Next, start the motor 2 11 on the outer wall of the mounting plate 12, which drives the rotating rod 2 13 to rotate. The movement of the rotating rod 2 13 drives the pressure strip 14 to rotate, thereby stabilizing the position of the paper bag. At the same time, the hydraulic rod 25 rises, releasing the pressure of the upper pressure plate 26. After starting the motor 14, the rotating rod 15 begins to rotate. The rotation of the rotating rod 15 pushes the connecting block 6, and the movement of the connecting block 6 drives the folding plate 7 to flip over. During the flipping process of the folding plate 7, the cushion 8 plays a role in protecting the paper bag. When the folding plate 7 is completely folded and fits with the pressure strip 14, it means that the folding of the paper bag is completed. This collaborative system greatly improves the efficiency and accuracy of the operation, ensuring that the paper bag can complete the folding task quickly and accurately in the production process.
[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the top of the workbench 1 is fixedly connected to a bracket 15, the top of the bracket 15 is fixedly connected to an electric push rod 16, and at the same time, the output end of the electric push rod 16 is fixedly connected to a limit block 17, and the limit block 17 is slidably connected in the bracket 15, the top of the bracket 15 is fixedly connected to a pair of fixed blocks 18, a pair of positioning rods 19 are fixedly connected between the fixed blocks 18 on both sides, and the limit block 17 is slidably connected to the outer wall of the positioning rod 19, the bottom of the limit block 17 is fixedly connected to a connecting plate 20, the bottom of the connecting plate 20 is fixedly connected to an electric push rod 21, the output end of the electric push rod 21 is fixedly connected to a suction cup 22, and the top of the suction cup 22 is fixedly connected to an air pump 23, the output end of the air pump 23 is fixedly connected to an air outlet pipe 24, and the air outlet pipe 24 passes through the air pump 23 and extends into the suction cup 22, and the hydraulic rod 25 is fixedly connected to the bottom of the connecting plate 20.
[0028] The paper bag is first transported by conveyor belt 2 to the bottom of bracket 15, where it then stops. At this point, electric push rod 16 activates, pushing stop block 17 along positioning rod 19 to ensure consistent movement. The movement of stop block 17 also drives connecting plate 20 forward. This movement activates suction cup 22 on electric push rod 21, causing it to descend to the position of the paper bag. Air pump 23 activates, extracting air from suction cup 22, creating a vacuum. Suction cup 22 uses this vacuum to lift the paper bag. Simultaneously, electric push rod 16 coordinates its movement, moving the paper bag to the position of fixed plate 3, ensuring it is securely held. Then, electric push rod 21 pushes the paper bag between positioning blocks 9 on either side of fixed plate 3. Once the paper bag is precisely positioned, air pump 23 is turned off, allowing suction cup 22 to return to normal operation, and the paper bag is precisely dropped from suction cup 22. This series of coordinated actions effectively realizes a fast loading process and significantly improves the working efficiency and production capacity of the production line.
[0029] Working principle: when the staff needs to fold the paper bag, the paper bag is first transported by the conveyor belt 2 and stops when it is transported to the bottom of the bracket 15. At this time, the electric push rod 16 is started to push the limit block 17 forward. At the same time, the limit block 17 is limited on the positioning rod 19 to ensure that the movement direction of the limit block 17 remains consistent. When the limit block 17 moves, the connecting plate 20 at the bottom is driven to move. The movement of the connecting plate 20 will drive the suction cup 22 on the electric push rod 21 to start. At this time, the electric push rod 21 is started to push the suction cup 22 down to the paper bag position. The air inside the suction cup 22 is discharged through the air outlet pipe 24 by starting the air pump 23 to make it vacuum. At this time, the paper bag is clamped and moved up by the suction cup 22. The paper bag is driven to the position of the fixed plate 3 by the start of the electric push rod 16, and pushed to between the positioning blocks 9 on both sides of the fixed plate 3 by the electric push rod 21. When the air pump 23 is turned off, the suction cup 22 is turned off. At this time, the air enters and the paper bag falls accurately. Through the cooperation between them, the effect of fast feeding is achieved, which improves work efficiency. At this time, the hydraulic rod 25 is started to drive the upper pressure plate 26 to move down and press the paper bag into position. At this time, the motor 21 on the outer wall of the mounting plate 12 is started. Under the action of the motor 21, the rotating rod 21 is driven to rotate. The rotation of the rotating rod 213 will drive the pressure strip 14 to rotate, thereby fixing the paper bag. At this time, the upper pressure plate 26 moves up through the hydraulic rod 25, and then the motor 14 is started. The start of the motor 14 will drive the rotating rod 15 to rotate. Under the rotation of the rotating rod 15, a pair of connecting blocks 6 are rotated. Under the rotation of the connecting block 6, the folding plate 7 is flipped, thereby folding the paper bag. At the same time, the soft pad 8 can protect the paper bag. When the folding plate 7 is completely folded and fits the pressure strip 14, the folding is completed. With the cooperation between them, the work efficiency is greatly improved.
