[0020] like Figures 1 to 6 As shown, a bag pushing assembly includes a housing 1, the housing 1 includes a top plate 100, a rear end plate 101 is arranged on the left side of the top plate 100, rear side plates 102 are arranged on both sides of the rear end plate 101, and a lining plate 103 is arranged between the two rear side plates 102 and close to the top plate 100. A rear mounting plate 104 is arranged on the lower side between the two rear side plates 102.

[0021] A front end plate 105 is disposed at the right end portion of the housing 1 , front side plates 106 are disposed on both sides of the front end plate 105 , and a connecting plate 107 is disposed at the lower side between the two rear side plates 106 .

[0022] Two supports 108 are arranged in the middle of the connecting plate 107. The supports are inclined to the lower left, and the upper right end of the supports is fixed on the connecting plate. The left end of the supports 108 is provided with holes, and the holes of the two supports 108 are concentric.

[0023] The transmission shaft 202 of the bag pressing mechanism 2 is installed in the concentric holes of the two supports 108, and a connector 200 is installed at one end of the transmission shaft 202. The connector 200 is connected to the fisheye joint 207 installed at the end of the guide rod of the bag pressing cylinder 204 by a pin 201. A cross transmission member 205 is arranged in the middle of the bag pressing cylinder 204, and the rotating shafts on both sides of the cross transmission member 205 are respectively connected to the mounting seats 206 on both sides. The mounting seats 206 are installed on the top plate 100 of the housing 1.

[0024] A pressing plate 203 is arranged on both sides of the middle of the transmission shaft 202, and the pressing plate 203 is in an "L" shape. When the bag needs to be blocked during operation, the lower part of the "L" shape is parallel to the material bag. The distance between the two "L" shaped pressing plates is greater than the width of the buckle.

[0025] like Figures 1 to 6 As described above, a rodless cylinder 311 is installed between the rear mounting plate 104 and the connecting plate 107 of the housing 1. The rodless cylinder 311 is located on the upper side of the rear mounting plate 104 and the connecting plate 107.

[0026] The sliding seat 312 of the rodless cylinder 311 is provided with a bag pushing mechanism 3 on the sliding seat 312. The bottom plate 303 of the bag pushing mechanism 3 is connected to the sliding seat 312 of the rodless cylinder 311. A vertical plate 300 connected thereto is provided in the middle position of the bottom plate 303, and a reinforcing plate 302 is provided on the right side of the vertical plate 300. A support ear 301 is provided on the upper left end of the vertical plate 300. A flip cylinder 304 is installed on the support ear 301 with a rotating pin 1 309. The flip cylinder 304 passes through the hole of the top plate 100 of the shell 1, and a joint 310 is installed on the guide rod end, and the joint 310 is connected to the middle protruding position of the swing arm 306 with a rotating pin 2 313. A push plate 305 is provided at the lower right end of the swing arm 306. The side of the push plate 305 is parallel to the material bag.

[0027] The upper end of the swing arm 306 is connected to the rotating shaft 307, and the rotating shaft 307 is installed on the rotating seat 308 and connected to the swing arm on the other side. The rotating seat 308 is connected to the bottom of the vertical board 300.

[0028] like Figure 7 , 8 As shown, when working, the slide seat 312 of the rodless cylinder 311 is initially on the rightmost side of the cylinder. The guide rod of the bag pressing cylinder 204 of the bag pressing mechanism 2 contracts and drives the connecting piece 200 to rotate counterclockwise, driving the transmission shaft 202 and the pressing plate 203 to flip upward. At this time, the material bag 5 with the buckle hand is manually inserted into the bag hanging rod 4 using the opposite perforation of the buckle hand. After hanging, the pressing plate 203 extends from the guide rod of the bag pressing cylinder 204, and the guide rod drives the connecting piece 200 to rotate clockwise, driving the transmission shaft 202 and the pressing plate 203 to flip downward until the pressing plate 203 blocks the material bag 5.

[0029] The bag taking device 6 continuously takes away the material bag 5 at the front end of the bag stack. When the bag taking device 6 cannot detect any material bag in the bag stack, it means that there is no material bag in the bag stack. At this time, the guide rod of the turning cylinder 304 on the bag pushing mechanism 3 contracts, driving the swing arm 306 to rotate clockwise around the rotating shaft 307, driving the push plate 305 to turn, and at this time, the slide seat 312 of the rodless cylinder 311 moves from right to left to the leftmost end of the rodless cylinder.

[0030] The various structures mentioned in the present invention are not the only ways to implement the bag pushing method. With the help of the present invention, ordinary persons in the technical field can make appropriate changes to implement the bag pushing function, which all fall within the protection scope of the present invention.
