[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-8 As shown, a compaction and drying device for cardboard production includes a stand 101 and a pressure plate 102. The stand 101 is provided with a compaction groove 1011, and the pressure plate 102 is located inside the compaction groove 1011. Heating resistors are respectively provided on the pressure plate 102 and the stand 101 to enable the pressure plate 102 and the stand 101 to heat up. The stand 101 and the pressure plate 102 are placed vertically, so that the compaction groove 1011 is in a vertical state. When the pressure plate 102 is disengaged from the bottom of the compaction groove 1011, the top side wall of the compaction groove 1011 is in an open state. The groove opening of the compaction groove 1011 is set at the top position, and the pressure plate 102 is set at the side wall position to avoid collision between the driving components on the pressure plate 102 and the cardboard being transported by the robot or the crane, which facilitates the loading and unloading of the cardboard and protects the drying equipment.

[0037] Furthermore, the side wall of the compaction groove 1011 is provided with an opening 1013, and a baffle 103 is provided inside the opening 1013. The width of the baffle 103 is smaller than the width of the opening 1013. A slide rod 1031 is provided on the baffle 103, and a protrusion 117 is provided on the side wall of the stand 101. The protrusion 117 is provided with a first sliding groove for the slide rod 1031 to move. A first spring 118 is provided on the slide rod 1031, and a first push plate 104 is provided on the pressure plate 102. By utilizing the design of the opening 1013, the height of the robot or the crane can be reduced. After the robot or the crane clamps the cardboard, it can push the cardboard... The cardboard is placed into the compaction groove 1011 through the opening 1013. The compaction groove 1011 has an opening 1013 on only one side. After the cardboard enters the compaction groove 1011 through the opening 1013, it abuts against the other side wall of the compaction groove 1011 to position the cardboard, making it easier to put the cardboard into the compaction groove 1011 for drying. When the pressure plate 102 compacts the cardboard, the first push plate 104 pushes the baffle 103 to move, causing the baffle 103 to move towards the inner wall of the compaction groove 1011, reducing heat loss in the compaction groove 1011 and making the cardboard dry quickly.

[0038] Furthermore, the bottom of the stand 101 is provided with a second push plate 106, the bottom side wall of the compaction groove 1011 is provided with a receiving groove 1012 corresponding to the second push plate 106, and the stand 101 is also provided with an electric push rod 105 that drives the second push plate 106 to move to the top of the stand 101.

[0039] The stand 101 is provided with a first cavity, a first movable groove is provided on one side wall of the first cavity, and a second movable groove is provided on the other side wall. The first movable groove communicates with the compaction groove 1011. A first movable rod 113 is provided in the first cavity. The first movable rod 113 is connected to the second push plate 106. An extension rod 111 is provided on the first movable rod 113. A third push plate 109 is provided on the extension rod 111. The third push plate 109 extends out from the second movable groove.

[0040] A movable plate 107 is provided in the first cavity, and a support plate 108 is provided on the movable plate 107. The cross section of the support plate 108 corresponds to the cross section of the first movable groove. The support plate 108 fills the first movable groove to prevent the cardboard from deforming and entering the first movable groove when it is squeezed by the pressure plate 102, thus preventing damage to the cardboard. A second cavity is provided on the movable plate 107, and a first through groove is provided on the side wall of the second cavity. A first connecting rod 112 passes through the first through groove. The support plate 108 is connected to the first connecting rod 112. The first connecting rod 112 can move within the first through groove. The first through groove limits the movement trajectory of the first connecting rod 112, so that the support plate 108 can only move closer to or away from the movable plate 107.

[0041] A second through groove is provided on the side wall of the second cavity, and a second movable rod 119 is provided in the second through groove. A second connecting rod 114 is provided on the second movable rod 119. One end of the second connecting rod 114 is hinged to the second movable rod 119, and the other end is hinged to the first connecting rod 112.

[0042] A third movable rod is provided in the first cavity. A push block 1191 is provided on the third movable rod. A connecting block is provided on the third movable rod. The connecting block extends out of the first cavity. A first connecting plate 110 is provided on the connecting block. The first connecting plate 110 is located below the third push plate 109. The third push plate 109 is provided with a through hole through which the piston rod of the electric push rod 105 passes. The piston rod of the electric push rod 105 is fixedly connected to the first connecting plate 110.

[0043] The push block 1191 is provided with a third movable groove, and a third connecting rod 120 is provided in the third movable groove. The third connecting rod 120 is provided with a second spring 121 and a movable block 116. The movable plate 107 is provided with a first guide groove 1071 corresponding to the movable block 116. The movable plate 107 is also provided with a groove, one end of the second movable rod 119 is located in the groove, one end of the second movable rod 119 is provided with a second connecting plate 115, and the side wall of the groove is provided with a second guide groove 1072 corresponding to the movable block 116.

[0044] The second connecting plate 115 is provided with a fourth connecting rod 122, the fourth connecting rod 122 is provided with a slider 123, the inner wall of the first cavity is provided with a second sliding groove for the slider 123 to move, the slider 123 is provided with a third spring 124, and the third spring 124 abuts against the inner wall of the second sliding groove.

[0045] After the cardboard is dried, the pressure plate 102 moves back to its original position. The electric push rod 105 drives the first connecting plate 110 to move, and the third movable rod drives the push block 1191 to move. The movable block 116, which is abutting against the second connecting plate 115, moves to abut against the second guide groove 1072, causing the third connecting rod 120 to move into the third movable groove. The movable block 116 moves above the movable plate 107, and the third spring 124 pushes the slider 123 to move in the second slide groove. The second movable rod 119 moves relative to the movable plate 107 first. The support plate 108 moves towards the movable plate 107 and enters the first cavity. Then, the second connecting plate 115 drives the movable plate 107 to move together, so that the movable plate 107 moves to one side of the first movable groove. At this time, the first connecting plate 110 abuts against the bottom of the third push plate 109. The first connecting plate 110 drives the third push plate 109 to move. The second push plate 106 pushes the cardboard in the compaction groove 1011 upward, pushing the dried cardboard out of the compaction groove 1011 for easy picking by the robot or crane.

[0046] After the cardboard is removed from the compaction groove 1011, the electric actuator 105 drives the first connecting plate 110 to descend, and the third push plate 109 descends along with the first connecting plate 110. The second push plate 106 falls back into the receiving groove 1012. After the third push plate 109 moves to the bottom of the second movable groove, the electric actuator 105 continues to push the first connecting plate 110 to descend. The movable block 116 abuts against the first guide groove 1071 and pushes the movable plate 107 to move. The movable plate 107 moves to a position opposite to the first movable groove and abuts against the first cavity. Once the inner wall is immobilized, the movable block 116 continues to move and presses against the second connecting plate 115. The second spring 121 pushes the third connecting rod 120 to extend out of the third movable groove. The movable block 116 pushes the second connecting plate 115 to move. The second movable rod 119 moves into the second cavity, causing the second connecting rod 114 to rotate. The second connecting rod 114 pushes the first connecting rod 112 to move out of the second cavity. The support plate 108 moves into the first movable groove to fill the first movable groove, so that the inner wall of the compaction groove 1011 forms a complete plane.
