Driven by the cylinder module 43, the bag mouth of the woven bag 8 stretched on the workpiece platform 2 is folded, the first electromagnetic clutch 41 is connected to the third cylinder module 44, and when the first electromagnetic clutch 41 is driven by the third cylinder module 44 and the first preset distance from the built-in electromagnet 26 of the fixed wheel rod 21, the fixed wheel rod 21 rotates to drive the woven bag 8 to rotate, and the bag mouth of the woven bag 8 is completely folded under the action of the flanging mold 42; the third station 5 is an ultrasonic welding station, and the third station 5 includes an ultrasonic welding machine 51, a second electromagnetic clutch 52, a fourth cylinder module 53 and a fifth cylinder module 54, and the ultrasonic welding machine 51 is connected to the fourth cylinder module 53 The second electromagnetic clutch 52 is connected to the fifth cylinder module 54. When the second electromagnetic clutch 52 is driven by the fifth cylinder module 54 to a second preset distance from the built-in electromagnet 26 in the fixed wheel rod 21, the fixed wheel rod 21 rotates to drive the woven bag 8 to rotate. At the same time, the fourth cylinder module 53 drives the ultrasonic welding machine 51 to extend into the edge of the woven bag 8 to perform ultrasonic welding on the folded edge of the woven bag 8. The fourth station 6 is a woven bag unloading station. The fourth station 6 includes a cylinder flipping assembly 61. The first cylinder module 24 extends and pushes open the moving wheel rod 22 to loosen the woven bag 8. The cylinder flipping assembly 61 flips the woven bag 8 to detach from the workpiece platform 2.

[0023] In the above embodiment, preferably, the fully automatic woven bag folding welding machine also includes a photoelectric deceleration and stop component, which is respectively installed at the first station 3, the second station 4, the third station 5 and the fourth station 6; the photoelectric deceleration and stop component includes a deceleration photoelectric switch and a stop photoelectric switch, and the deceleration photoelectric switch is installed upstream of the conveying direction of the chain conveyor line 1 relative to the stop photoelectric switch. The workpiece platform 2 decelerates when passing through the deceleration photoelectric switch driven by the chain 13, and stops when passing through the stop photoelectric switch.

[0024] In this embodiment, specifically, in the chain conveyor line 1, the motor 11 drives the chain 13 to realize circular motion, and each station is respectively provided with a deceleration photoelectric switch and a stop photoelectric switch, and the deceleration photoelectric switch is arranged upstream of the conveying direction of the chain 13, and the stop photoelectric switch is arranged downstream of the conveying direction of the chain 13, that is, the workpiece platform 2 first triggers the deceleration photoelectric switch to realize deceleration, and then triggers the stop photoelectric switch to realize that the workpiece platform 2 stops at the current station, so as to realize the accurate positioning of each station. Driven by the chain 13, the workpiece platform 2 passes through the first station 3, the second station 4, the third station 5 and the fourth station 6 in sequence to complete a set of actions, and the cycle is repeated to realize the action of the entire assembly line. Among them, the chain conveyor line 1 is mainly composed of a servo motor 11, 8 sprocket wheels 12 and 2 sections of chain 13, and the servo motor 11 drives the chain conveyor line 1 to realize circular motion.

[0025] The workpiece platform 2 passes through the deceleration photoelectric switch and the stop photoelectric switch in sequence, and finally stops at the first station 3. At the first station 3, after the operator prepares the woven bag 8, he steps on the button pedal to control the first cylinder module 24 to drive the connecting rod 25 to push the spring 23 and move the moving rod, wherein the moving wheel rod 22 is connected to the spring 23. At this time, the woven bag 8 is put on the fixed wheel rod 21 and the moving wheel rod 22, and the button pedal is released. At this time, the first cylinder module 24 contracts, driving the connecting rod 25 to return to the original position, and the moving wheel rod 22 is pushed back to the original position by the spring 23, thereby tightening the bag mouth of the woven bag 8, that is, realizing the bagging tension of the woven bag 8.

[0026] Among them, after the action of the first station 3 is completed, the chain conveyor line 1 drives the workpiece platform 2 to continue conveying, passes through the deceleration photoelectric switch and the stop photoelectric switch in sequence, and stops at the second station 4. At the second station 4, the first electromagnetic clutch 41, the flanging mold 42, the second cylinder module 43 and the third cylinder module 44 are all installed on the frame of the chain conveyor line 1. When the woven bag 8 arrives at the second station 4, the second cylinder module 43 drives the flanging mold 42 to move upward, and a small section of the woven bag 8 is folded 90°; the third cylinder module 44 drives the first electromagnetic clutch 41 to move upward, and when a certain distance (preferably 3-10mm) is reached between the fixed wheel rod 21 and the built-in electromagnet 26, the fixed wheel rod 21 rotates itself, thereby driving the woven bag 8 to rotate, and at the same time, the flanging mold 42 passes through each section of the woven bag 8 stably, and finally the entire bag mouth of the woven bag 8 is folded.

[0027] Among them, after the action of the second station 4 is completed, the chain conveyor line 1 drives the workpiece platform 2 to continue conveying, passes through the deceleration photoelectric switch and the stop photoelectric switch in turn, and stops at the third station 5. At the third station 5, the ultrasonic welding machine 51, the second electromagnetic clutch 52, the fourth cylinder module 53 and the fifth cylinder module 54 are all installed on the frame of the chain conveyor line 1. When the woven bag 8 reaches the third station 5, the fifth cylinder module 54 drives the second electromagnetic clutch 52 to move upward. When it reaches a certain distance (preferably 3-10mm) from the built-in electromagnet 26 in the fixed wheel rod 21, the fixed wheel rod 21 rotates itself, thereby driving the woven bag 8 to rotate. At the same time, the fourth cylinder module 53 drives the ultrasonic welding machine 51 to the edge of the bag mouth of the woven bag 8, completing the ultrasonic welding action of the folded edge of the woven bag.

[0028] After the action of the third station 5 is completed, the chain conveyor line 1 drives the workpiece platform 2 to continue conveying, passes through the deceleration photoelectric switch and the stop photoelectric switch in sequence, and stops at the fourth station 6. At the fourth station 6, after the woven bag 8 reaches the fourth station 6, the first cylinder module 24 extends to push open the moving wheel rod 22, and the distance between the moving wheel rod 22 and the fixed wheel rod 21 becomes smaller, so that the woven bag 8 is loosened. At this time, the cylinder in the cylinder flip assembly 61 drives the flip plate 62 to make a circular motion, thereby knocking off the drooping woven bag 8.

[0029] In the above embodiment, preferably, the fully automatic woven bag folding welding machine also includes a finished product conveyor line 7, which is arranged at the end of the fourth workstation 6. The conveying direction of the finished product conveyor line 7 is along the flipping direction of the fourth workstation 6.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
