[0002] In the process of sealing the packaging box with a sealing machine, it is necessary to seal the lid of the plastic box with tape, and in this process, it is necessary to use a positioning clamping device to clamp the packaging box and perform rotation adjustment to assist in sealing. Although the positioning clamping device of the existing sealing machine can meet the basic needs of clamping and rotating the packaging box, the placement structure for placing the packaging box is often directly connected to the rotating shaft, and there is no support between the bottom side end of the placement structure and the workbench, so that the placement structure cannot be firmly supported, and it is easy to cause the placement structure to tilt to one side after a long period of work, thereby affecting the stability of the device and the clamping effect of the packaging box.

[0003] For example, the utility model with announcement number CN 216862014 U discloses a clamping mechanism of a food packaging box sealing machine. In the technical solution of this patent, a turntable for placing the packaging box is directly connected to the upper end of the rotating shaft, and there is no rotating support structure between the bottom side end of the turntable and the workbench. Therefore, there is a defect that the stability of the turntable is easily affected by the side of the turntable being suspended in the air, thereby affecting the clamping effect of the packaging box, which will bring great inconvenience to people's use.

[0025] like Figure 1 As shown, a bearing 112 is disposed on the top of the processing table 101 , and the connecting shaft 103 is connected to the inner ring of the bearing 112 .

[0026] The user can adjust the threaded connecting rod 110 by twisting it according to the distance between the bottom of the placement plate 104 and the top of the processing table 101, thereby adjusting the expansion and contraction amount of the threaded connecting rod 110 in the threaded connecting cylinder 109, so that the ball 111 can contact the bottom of the processing table 101. After that, the packaging box can be placed on the placement plate 104, and then the output shaft of the telescopic push rod 106 can be extended downward by a certain length, so that the pressing plate 108 can press the top of the packaging box, and then the driving motor 107 can be started to make the pressing plate 108, the packaging box, the placement plate 104, and the connecting shaft 103 rotate synchronously, so that the user can easily seal a circle of the connection between the box body and the box cover of the packaging box; during the rotation of the placement plate 104, the threaded connecting tube 109, the threaded connecting rod 110 and the ball 111 can cooperate to provide auxiliary support for the rotation of the placement plate 104, so as to prevent the placement plate 104 from tilting to one side, so that the placement plate 104 can run smoothly, thereby avoiding affecting the clamping effect of the packaging box.

[0027] After the sealing process of the packaging box is completed, the output axis of the telescopic push rod 106 can be shortened by a certain length, so that the pressing plate 108 moves upward, releasing the pressing and rotating drive of the packaging box, and then the packaging box can be taken away from the placement tray 104.

[0028] According to another embodiment of the present invention, Figure 3As shown, the top of the placement plate 104 is provided with a first connection sleeve 201, the top of the first connection sleeve 201 is provided with a first anti-skid pattern 202, the side end of the first connection sleeve 201 is also provided with a first connection bolt 203 for screwing and fixing the placement plate 104, and the placement plate 104 is provided with a first threaded connection hole adapted to the first connection bolt 203. It is only necessary to make the first connection sleeve 201 and the placement plate 104 clamped and fixed, and then make the first connection bolt 203 pass through the side wall of the first connection sleeve 201 and be screwed and fixed with the first threaded connection hole, so that the first anti-skid pattern 202 and the placement plate 104 can be flexibly fixed; after that, it is only necessary to separate the first connection bolt 203 from the first threaded connection hole, and then the first connection sleeve 201 and the first anti-skid pattern 202 can be removed and replaced together. The first connection bolt 203 is a hand-tightened bolt, and the user can easily turn and adjust the first connection bolt 203.

It is only necessary to clamp and fix the second connecting sleeve 204 with the pressing plate 108, and then pass the second connecting bolt 206 through the side wall of the second connecting sleeve 204 and screw and fix it with the second threaded connection hole, so that the second anti-skid pattern 205 and the pressing plate 108 can be flexibly fixed; after that, it is only necessary to separate the second connecting bolt 206 from the second threaded connection hole, and then the second connecting sleeve 204 and the second anti-skid pattern 205 can be removed and replaced together. The second connecting bolt 206 is a hand-tightening bolt. The user can conveniently turn and adjust the second connecting bolt 206 by hand.

[0030] According to another embodiment of the present invention, Figure 2 As shown, a plurality of threaded connecting rods 110 are also provided with a screw handle 113. Through the screw handle 113, the threaded connecting rod 110 can be conveniently screwed and adjusted.
