[0023] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 7 As shown, this embodiment provides a skin-friendly diaper automated production line, including a frame 1, a diaper shaping and pushing system 2, a diaper bag heat-sealing system 3, a bag body opening system 4, a bag body conveying system 5 and a bag body pushing back system 6 respectively installed on the frame 1. The pushing direction of the diaper shaping and pushing system 2 points to the bag body opening system 4, pushing the arranged diapers to the bag body opening system 4. The diaper bag heat-sealing system 3 is located between the diaper shaping and pushing system 2 and the bag body opening system 4. The bag body opening system 4 includes a bag body lifting device 41, a bag body pulling down device 42, an upper bag opening clamping device 43 and a lower bag opening clamping device. The bag body lifting device 41 It is arranged opposite to the bag body pulling-down device 42, the upper bag opening clamping device 43 is installed on the upper side of the bag body lifting device 41, and the lower bag opening clamping device is installed on the lower side of the bag body pulling-down device 42. When the diaper stack is pushed into the bag body, the bag body of the packaging bag 8 is prevented from detaching from the bag body lifting device 41 and the bag body pulling-down device 42. The bag body conveying system 5 is installed on the lower side of the bag body pushing back system 6, and the bag body opening system 4 is installed between the bag body conveying system 5 and the diaper bag heat sealing system 3 to open the bag body of the packaging bag 8. The pushing direction of the bag body pushing back system 6 points to the diaper bag heat sealing system 3, pushing the opening part of the bag body of the packaging bag 8 toward the diaper bag heat sealing system 3 to achieve heat sealing.

[0024] Specifically, the upper bag opening clamping device 43 includes an upper pneumatic extrusion device 431 and an upper eccentric clamping device 432, both of which are installed on the bag body lifting device 41, and the upper pneumatic extrusion device 431 is located on the upper side of the upper eccentric clamping device 432, and an upper bag seam is formed between the upper pneumatic extrusion device 431 and the upper eccentric clamping device 432, and an upper blowing port 4311 pointing to the upper bag seam is provided on the lower side of the upper pneumatic extrusion device 431. 4311 is connected to an air pump, and the upper eccentric clamping device 432 includes a plurality of upper clamping wheels 4321, each of which is rotatably mounted on the bag body lifting device 41 in an eccentric manner, and each of the upper clamping wheels 4321 is deflected toward the side close to the diaper shaping pushing system 2, and a torsion spring is provided between the upper clamping wheel 4321 and the bag body lifting device 41 to maintain the posture of the upper clamping wheel 4321. In order to prevent the upper clamping wheel 4321 from excessive rotation, a rotation limit position of the upper clamping wheel 4321 is limited on the bag body lifting device 41. The limit pin is provided. Before bagging, the packaging bag 8 is opened manually and the bag opening of the packaging bag 8 is put on the bag lifting device 41 and the bag pulling device 42. The bag lifting device 41 and the bag pulling device 42 are moved away from each other, thereby opening and fixing the bag opening of the packaging bag 8. After the whole pile of diapers is pushed in, the upper pneumatic squeezing device 431 presses the packaging bag 8 downward toward the upper eccentric clamping device 432, so that the packaging bag 8 is pressed against the upper eccentric clamping device 432. If the packaging bag 8 is moved away from the diaper shaping and pushing system 2, the packaging bag 8 will be pressed against the upper eccentric clamping device 432. When the upper clamping wheel 4321 is rotated, the packaging bag 8 drives the upper clamping wheel 4321 to rotate. Since the upper clamping wheel 4321 is deflected toward the side close to the diaper shaping and pushing system 2, the upper clamping wheel 4321 squeezes the packaging bag 8 toward the upper pneumatic squeezing device 431 when the upper clamping wheel 4321 rotates, thereby causing the upper pneumatic squeezing device 431 and the upper eccentric clamping device 432 to clamp the packaging bag 8. The more the packaging bag 8 moves, the greater the clamping force is, which prevents the packaging bag 8 from moving, so that the packaging bag 8 is firmly fixed when the diapers are bagged, ensuring smooth bagging.

[0025] The lower bag opening clamping device is opposite to the upper bag opening clamping device 43, and the lower bag opening clamping device includes a lower pneumatic extrusion device and a lower eccentric clamping device, both of which are installed on the lower side of the bag body pulling-down device 42, and the lower pneumatic extrusion device is located on the lower side of the lower eccentric clamping device, and a lower bag seam is formed between the lower pneumatic extrusion device and the lower eccentric clamping device. The upper side of the lower pneumatic extrusion device is provided with a lower blowing port pointing to the lower bag seam, and the lower blowing port is connected to an air pump, and the lower eccentric clamping device includes a plurality of lower clamping wheels, each of which is rotatably installed on the lower side of the bag body pulling-down device 42 in an eccentric manner, and each lower clamping wheel is deflected toward the side close to the diaper shaping pushing system 2, and a torsion spring is provided between the lower clamping wheel and the bag body pulling-down device 42 to maintain the posture of the lower clamping wheel. In order to prevent the lower clamping wheel from excessive rotation, a limit position for limiting the rotation of the lower clamping wheel is provided on the bag body pulling-down device 42. The bag is then opened and the bag opening is fixed on the upper and lower bag seams by the lower pneumatic extrusion device 41 and the lower pouch pulling device 42. The bag lifting device 41 and the bag pulling device 42 are moved away from each other, thereby opening and fixing the bag opening of the bag 8. After the whole pile of diapers is pushed in, the lower pneumatic extrusion device presses the bag 8 downward toward the lower eccentric clamping device, so that the bag 8 is pressed on the lower eccentric clamping device. If the bag 8 slides in the direction away from the diaper shaping and pushing system 2, the bag 8 drives the lower clamping wheel to rotate. Since the lower clamping wheel deflects toward the side close to the diaper shaping and pushing system 2, the lower clamping wheel squeezes toward the side of the lower pneumatic extrusion device of the bag 8 when the lower clamping wheel rotates, thereby causing the lower pneumatic extrusion device and the lower eccentric clamping device to clamp the bag 8 to prevent the bag 8 from moving. The bag 8 is firmly fixed when the diapers are bagged, ensuring smooth bagging.

[0026] Specifically, the diaper shaping and pushing system 2 includes two diaper shaping clamping devices 21 arranged opposite to each other and a shaping pushing device 22 sliding between the two diaper shaping clamping devices 21. The diaper shaping clamping devices 21 and the shaping pushing device 22 are both installed on the frame 1.

The retreat avoidance device 62 is installed on the bag pushing back device 61. The retreat avoidance device 62 has a telescopic end pointing to the bag conveying system 5, and the telescopic end is composed of a cylinder. The pushing direction of the bag pushing back device 61 points to the diaper bag heat sealing system 3, pushing the bagged diapers to the diaper bag heat sealing system 3 for heat sealing.

[0030] Specifically, the bag lifting device 41 includes a lifting cylinder 411 and a lifting plate 412. The lifting cylinder 411 is installed on the frame 1, the lifting plate 412 is installed at the output end of the lifting cylinder 411, and the upper bag mouth clamping device 43 is installed on the lifting plate 412 to assist in fixing the upper side of the bag body of the packaging bag 8.
