The frame 101 is installed on one side of the winding machine. A set table 200 is provided on one side of the frame 101. The set table 200 is used to package the ground film roll.

[0019] An entrance for introducing the ground film roll is provided on one side of the frame 101, and a first baffle 103 is provided on the side opposite to the entrance. A second baffle 104 and a third baffle 105 are provided at both ends of the first baffle 103 respectively. The second baffle 104 and the third baffle 105 are located at both ends of the roller 102. The first baffle 103, the second baffle 104 and the third baffle 105 cooperate to limit the ground film roll to prevent the ground film roll from rolling to the outside of the frame 101.

[0020] A first electric push rod 106 is provided on the outer side of the second baffle 104, and a push plate 107 is provided on the inner side. The telescopic end of the first electric push rod 106 passes through the second baffle 104 and is connected to the push plate 107; a rotating shaft 112 is passed through the bottom of the third baffle 105, and both ends of the rotating shaft 112 are rotatably connected to the frame 101. One end of the rotating shaft 112 passes through the frame 101 and a gear 113 is provided at its end. A second electric push rod 109 is arranged in the horizontal direction on the outer side of the first baffle 103, and a rack 110 is provided at the end of the second electric push rod 109. The rack 110 is meshed with the gear 113. The second electric push rod 109 is telescopically driven to drive the rack 110 to move, and the third baffle 105 is driven to rotate through the gear 113 and the rotating shaft 112. After weighing, the top of the third baffle 105 rotates to the top surface of the set table 200, and the first electric push rod 106 pushes the ground film roll to the set table 200 through the push plate 107.

[0021] In one embodiment, an auxiliary support rod 108 is provided through the second baffle plate 104 . The auxiliary support rod 108 passes through the second baffle plate 104 , and an end portion thereof is connected to the push plate 107 . The auxiliary support rod 108 is used to auxiliary support the push plate 107 .

[0022] In one embodiment, the table top 201 on the top of the assembly table 200 is tilted, and the table top 201 is tilted toward the side away from the weighing mechanism 100, so as to facilitate the rolling of the ground film roll to the side close to the edge of the assembly table 200, and facilitate the operation of the staff. A fourth baffle 202 is provided on the edge of the table top 201, and the fourth baffle 202 is used to block the ground film roll to prevent the ground film roll from rolling off the table top 201 of the assembly table 200.

[0025] When the automatic weighing device for ground film roll is in use, the finished ground film roll is introduced into the weighing mechanism 100 and weighed by the pressure sensor 114. The first baffle 103, the second baffle 104 and the third baffle 105 can block the ground film roll to prevent it from rolling to the outside of the frame 101. After the weighing is completed, the second electric push rod 109 drives the rack 110 to move, and the rack 110 drives the gear 113 to rotate a certain angle, and drives the top of the third baffle 105 to rotate to the sleeve through the rotating shaft 112. The table top 201 of the mounting platform 200 and the third baffle 105 are in an inclined state. The first electric push rod 106 pushes the ground film roll through the push plate 107, and the ground film roll rolls to the table top 201 through the third baffle 105. Since the table top 201 is inclined, the ground film roll rolls to the side of the fourth baffle 202, and the cushion layer 203 cushions the impact of the ground film roll. The staff bags the ground film roll, and the weighing and transfer processes can be automated through PLC, without manual pushing, which is beneficial to improving the efficiency of ground film production.
