The bag suction mechanism 30 includes a first adsorption component 31. The first adsorption component 31 is used to adsorb the packaging bags 90 on the bag supplying station 22. An opening station 44 is provided at the end of the bag delivery mechanism 40. The bag delivery mechanism 40 is used to deliver the packaging bags 90 adsorbed by the first adsorption component 31 to the opening station 44. The opening mechanism 50 includes an upper adsorption component 51 and a lower adsorption component 52. The upper adsorption component 51 and the lower adsorption component 52 are used to open the packaging bags 90 at the opening station 44.

[0025] The bag feeding mechanism 20 includes a bag feeding conveying channel 21, which is used to convey the stacked packaging bags 90. The bag supply station 22 is arranged at the end of the bag feeding conveying channel 21. A baffle plate 23 is arranged at the end of the bag supply station 22, and baffle bars 24 are arranged on both sides of the bag supply station 22. The bag feeding conveying channel 21 conveys a stack of packaging bags 90 to the bag supply station 22 at intervals, and the baffle plate 23 and the baffle bar 24 limit the position of the packaging bags 90 at the bag supply station 22.

The first lifting seat 32 can be lifted and lowered by a cylinder or the like, and the first lifting seat 32 drives the first suction member 31 to move up and down. When the first suction member 31 moves down, it suctions the packaging bag 90 on the bag supply station 22, and when the first suction member 31 moves up, it drives the packaging bag 90 to move up to the front end position of the bag feeding mechanism 40.

[0027] The bag feeding mechanism 40 includes a first conveyor belt 41, a second conveyor belt 42 and a transition plate 43. The first conveyor belt 41 is arranged at one side of the bag suction mechanism 30, the second conveyor belt 42 is arranged directly below the first conveyor belt 41, the transition plate 43 is fixed at the rear end of the bag feeding station 22 and arranged at the front end of the second conveyor belt 42, specifically, the transition plate 43 is fixed on the baffle 23, and the opening station 44 is arranged at the ends of the first conveyor belt 41 and the second conveyor belt 42. The first suction member 31 feeds the packaging bag 90 under the first conveyor belt 41, and the packaging bag 90 first transitions through the transition plate 43, then enters between the first conveyor belt 41 and the second conveyor belt 42 and is transported to the opening station 44 by the first conveyor belt 41 and the second conveyor belt 42.

[0028] A bag bin adsorption mechanism 80 is provided above the bag supply station 22, and the bag bin adsorption mechanism 80 includes a bag bin adsorption component, which is provided at the front end of the bag delivery mechanism 40, and is used for adsorbing the packaging bag 90 on the bag suction mechanism 30 and delivering the packaging bag 90 to the bag delivery mechanism 40; the vacuum generating mechanism 10 includes a third air delivery pipe 110, one end of the third air delivery pipe 110 is connected to the filter element 13, and the other end is connected to the bag bin adsorption component, and a third solenoid valve 111 is provided on the third air delivery pipe 110.

[0029] Specifically, the bag bin suction piece is arranged at a position above the front end of the first conveyor belt 41, and an air hole is opened on the first conveyor belt 41. When the first suction piece 31 delivers the packaging bag 90 to the bottom of the first conveyor belt 41, the first suction piece 31 stops suction, and the bag bin suction piece starts suction. The packaging bag 90 is adsorbed by the bag bin suction piece under the first conveyor belt 41 and conveyed by the first conveyor belt 41. Due to the effect of the bag bin suction piece, the packaging bag 90 will not fall during the conveying process until the packaging bag 90 passes through the transition plate 43 and enters between the first conveyor belt 41 and the second conveyor belt 42. At this time, the packaging bag 90 loses the suction of the bag bin suction piece. With the cooperation of the bag bin suction piece, the first conveyor belt 41, the second conveyor belt 42 and the transition plate 43, the packaging bag 90 is smoothly delivered to the opening station 44.

[0030] The opening mechanism 50 includes a linear moving module 53, a moving plate 54, a first movable frame 55, a second movable frame 56 and an adjusting assembly 57. The linear moving module 53 is fixed at the rear end of the bag feeding mechanism 40. The moving plate 54 moves on the linear moving module 53. The first movable frame 55 and the second movable frame 56 are both connected to the moving plate 54. The upper adsorption component 51 is fixed on the first movable frame 55. The lower adsorption component 52 is fixed on the second movable frame 56. The adjusting assembly 57 is used to adjust the distance between the upper adsorption component 51 and the lower adsorption component 52.

[0031] There are two groups of adjustment components 57, which respectively adjust the upper adsorption component 51 to move upward and adjust the lower adsorption component 52 to move downward. The adjustment component 57 includes an adjustment cylinder, one end of which is hinged on the movable plate 54, and the other end is hinged on the first movable frame 55 or the second movable frame 56. The first movable frame 55 and the second movable frame 56 are both rotatably arranged on the movable plate 54. By adjusting the extension and contraction of the adjustment cylinder, the distance between the upper adsorption component 51, the lower adsorption component 52 and the movable plate 54 is adjusted, so that the upper adsorption component 51 and the lower adsorption component 52 rotate upward or downward relative to the movable plate 54, thereby realizing the adjustment of the distance between the upper adsorption component 51 and the lower adsorption component 52.

[0032] The upper adsorption member 51 and the lower adsorption member 52 adsorb the upper and lower surfaces of the packaging bag 90 respectively. When the distance between the upper adsorption member 51 and the lower adsorption member 52 increases, the opening of the packaging bag 90 is opened, and at the same time, the linear moving module 53 drives the packaging bag 90 to move to the bag supporting mechanism 60.

[0033] The packaging device includes a bag-supporting mechanism 60, a pushing mechanism 70 and a sealing mechanism. The opening mechanism 50 is used to deliver the opened packaging bag 90 to the bag-supporting mechanism 60. The pushing mechanism 70 pushes the stacked sanitary napkins into the opened packaging bag 90 on the bag-supporting mechanism 60 and then pushes them to the sealing mechanism. The sealing mechanism is used to seal the opened packaging bag 90.

[0034] The bag supporting mechanism 60 includes a rotating mechanism 61, a rotating frame 62 and two bag supporting members 63 symmetrically fixed on the rotating frame 62. The rotating mechanism 61 is used to drive the rotating frame 62 to rotate. The front end of the bag supporting member 63 can be opened and contracted. When the front end of the bag supporting member 63 is opened, a feeding channel 64 is formed inside the bag supporting member 63. A through hole is opened on the rotating frame 62 for the pushing mechanism 70 to pass through, and the through hole is connected to the feed channel 64.

[0035] The linear moving module 53 drives the upper adsorption component 51 and the lower adsorption component 52 to adsorb the opened packaging bag 90 and move to the position of a bag supporting component 63. At this time, the front end of the bag supporting component 63 shrinks, and the packaging bag 90 is put on the bag supporting component 63. Then the front end of the bag supporting component 63 opens, and the packaging bag 90 is firmly put on the bag supporting component 63. The feeding channel 64 opens, and the rotating mechanism 61 drives the rotating frame 62 to rotate 180°, and the bag supporting component 63 with the packaging bag 90 also rotates 180°. The other bag supporting component 63 rotates to the position where the upper adsorption component 51 and the lower adsorption component 52 send the packaging bag 90 into the bag supporting mechanism 60 for re-bagging.

[0036] The pushing mechanism 70 includes a pushing cylinder 71, a feed conveyor belt 72 and a lifting transition frame. The pushing cylinder 71 is fixed at the rear end of the bag supporting mechanism 60, and the feed conveyor belt 72 is fixed below the pushing cylinder 71. The lifting transition frame includes a second lifting seat 73 and a transition frame 74. The transition frame 74 is fixed on the second lifting seat 73 and is arranged at the end of the feed conveyor belt 72. The transition frame 74 is at the same height as the feed conveyor belt 72 when in the starting position, and is at the same height as the pushing end of the pushing cylinder 71 when in the rising position.

[0037] Working principle: The vacuum generator 11 works, and the adsorption of each adsorbent is adjusted through multiple solenoid valves. Specifically, the bag feeding conveying channel 21 conveys a stack of packaging bags 90 to the bag supply station 22 at intervals. The baffle 23 and the baffle rod 24 limit the position of the packaging bag 90 at the bag supply station 22. The first lifting seat 32 descends, and the first adsorbent 31 adsorbs the packaging bag 90 on the bag supply station 22 when it moves down. The first lifting seat 32 moves up, and the first adsorbent 31 drives the packaging bag 90 to move up to the bottom of the first conveyor belt 41 when it moves up. The bag bin adsorbent starts to adsorb, and the first adsorbent 31 stops adsorbing. The packaging bag 90 is adsorbed by the bag bin adsorbent at the first The packaging bag 90 is moved downwards by the conveyor belt 41 and conveyed by the first conveyor belt 41 until the packaging bag 90 passes through the transition plate 43 and enters between the first conveyor belt 41 and the second conveyor belt 42. The packaging bag 90 loses the adsorption of the bag bin adsorbent. The packaging bag 90 is then conveyed to the opening station 44 by the first conveyor belt 41 and the second conveyor belt 42. The upper adsorbent 51 and the lower adsorbent 52 simultaneously adsorb the packaging bag 90 at the opening station 44. When the upper adsorbent 51 and the lower adsorbent 52 move outwards with the movable plate 54, the adjusting component 57 respectively adjusts the upper adsorbent 51 to move upwards and adjusts the lower adsorbent 52 to move downwards. The upper adsorbent 51 and the lower adsorbent 52 respectively adsorb the upper and lower surfaces of the packaging bag 90. When the distance between the adsorbent 51 and the lower adsorbent 52 increases, the opening of the packaging bag 90 is opened. When the packaging bag 90 moves to the position of the bag-supporting member 63, the front end of the bag-supporting member 63 contracts, and the packaging bag 90 is sleeved on the bag-supporting member 63. Then the front end of the bag-supporting member 63 opens, and the packaging bag 90 is firmly sleeved on the bag-supporting member 63. The feeding channel 64 is opened, and the rotating mechanism 61 drives the rotating frame 62 to rotate 180°, and the bag-supporting member 63 with the packaging bag 90 also rotates 180°. The other bag-supporting member 63 rotates to the position where the upper adsorbent 51 and the lower adsorbent 52 send the packaging bag 90 into the bag-supporting mechanism 60, and the bag is re-baged. The bag-supporting member 63 that has been bagged rotates To the lower position; the sanitary napkins to be bagged are sorted by the sheet sorting machine and then enter the feed conveyor belt 72, and are sent to the position of the lifting transition frame by the feed conveyor belt 72 and smoothly enter the transition frame 74. The second lifting seat 73 drives the transition frame 74 to move up to a position at the same height as the pushing end of the pushing cylinder 71. The pushing cylinder 71 extends out to push the sanitary napkins on the transition frame 74, and the sanitary napkins pass through the through holes on the rotating frame 62 and enter the feed channel 64 in the bag supporting member 63. Then the pushing cylinder 71 continues to push the sanitary napkins, and the sanitary napkins drive the packaging bag 90 mounted on the bag supporting member 63 to move together until it moves to the sealing mechanism and is sealed by the sealing mechanism.

[0038] The utility model adopts a vacuum generator 11 in cooperation with a plurality of electromagnetic valves to realize the adsorption work of a plurality of adsorption parts on the packaging device, which not only reduces environmental noise but also saves more energy.
