[0031] The folding plate 20 is arranged on the front side of the fixed plate 10, and the folding plate 20 is connected with the moving plate 33, so that when folding different sizes of box bodies, the rotating rod 32 can be driven to rotate by the power piece 31, to drive the moving plate 33 to move up and down, so that the folding plate 20 is driven to move along the vertical direction, until the folding is adjusted to the required position, the power piece stops driving, so as to realize the automatic adjustment of the folding plate 20, without manual adjustment, which is helpful to reduce labor intensity, and can quickly adjust the position of the folding plate according to the size of different box bodies, shorten the adjustment time, and is helpful to provide folding efficiency.

The above is only an example, but is not limited thereto, and can also be a mechanism that can realize the up-and-down movement of the moving plate 33 in the prior art.

[0033] Please refer to Figure 4In an embodiment, the lower folding sealing mechanism of the packaging machine further comprises a position sensor 100 arranged on the back of the fixed plate 10, a through hole 33a is arranged on the moving plate 33, the position sensor 100 is fixed in the through hole, and the detection end of the position sensor 100 is directed to the back of the fixed plate 10 through the through hole 33a. An initial piece 200 is arranged on the back of the fixed plate as an initial point.

In addition, the through hole 10a is arranged in a strip shape, so that the movement of the connecting block is not limited when the moving plate 33 moves in the vertical direction, thereby ensuring that the folding sealing plate 20 can move back and forth smoothly.

[0037] In a possible implementation, two slide rails 40 are symmetrically arranged on the back surface of the fixed plate 10, and a sliding block 50 is slidably connected to the slide rails 40, and the sliding block 50 is connected to the surface of the moving block facing the fixed plate 10. In this way, the moving plate 33 can be ensured to move back and forth in a predetermined direction (i.e., a vertical direction), so as to avoid deviation of the position during the movement and affect the sealing effect of the sealing plate 20 on the lower edge of the packaging film.

[0038] In a possible implementation, the sliding block 50 is provided with a first fixing hole, and the moving plate 33 is provided with a second fixing hole matched with the first fixing hole. That is, the moving plate 33 is placed on the surface of the sliding block 50, and at this time, the second fixing hole is aligned with the first fixing hole, and then a fastener (e.g., a bolt) is sequentially inserted through the second fixing hole and the first fixing hole, so as to fixedly connect the moving plate 33 and the sliding block 50. The structure is simple, and the moving plate 33 is convenient to disassemble and assemble, so as to be convenient for subsequent replacement or maintenance.

[0039] In a possible implementation, the first mounting seat 70 and the second mounting seat 60 are arranged on the back surface of the fixed plate 10 in a spaced manner, and the first mounting seat 70 is located below the second mounting seat.

The two ends of the rotating rod 32 are respectively inserted into the first mounting hole and the second mounting hole, so that the rotating rod 32 is rotatably connected to the fixed plate 10.

[0040] In actual application, bearings are arranged at the first mounting hole and the second mounting hole, and then the two ends of the rotating rod 32 are respectively inserted into the first mounting hole and the second mounting hole, so that the two ends of the rotating rod 32 are rotatably connected to the first mounting hole and the second mounting hole, respectively. Thus, the rotating of the rotating rod 32 can be used to drive the moving plate 33 to move up and down.

[0041] In a possible implementation, the first mounting seat 70 has a protruding portion, and a connecting plate 34 is detachably connected to the protruding portion, and the power member 31 is mounted on the connecting plate 34.

[0042] In a possible implementation, the connecting plate 34 is provided with a first connecting hole, and the protruding portion is provided with a second connecting hole matched with the first connecting hole. That is, when the power member 31 is fixedly mounted, the power member 31 is first fixed on the connecting plate 34, and then the connecting plate 34 is brought into contact with the protruding portion, so that the first connecting hole and the second connecting hole are aligned, and then a fastener is sequentially inserted through the first connecting hole and the second connecting hole, so as to fixedly mount the power member 31. The structure is simple, and the power member 31 is convenient to disassemble and assemble, so as to be convenient for subsequent maintenance or replacement of the power member 31.

[0043] The working principle of the adjusting mechanism of the lower folding sealing mechanism of the packaging machine is as follows:

[0044] When folding and sealing box bodies of different specifications, the folding and sealing plates of the lower folding and sealing mechanism need to be adjusted to be suitable for folding and sealing box bodies of different specifications, for example, after folding and sealing the previous batch of box bodies with a thickness of 8 cm, the next batch of box bodies with a thickness of 12 cm need to be folded and sealed, and then the folding and sealing plates 20 in the upper folding and sealing mechanism and the lower folding and sealing mechanism need to be adjusted to ensure that the box bodies can pass smoothly and avoid the situation of jamming. For this purpose, the power member 31 drives the rotating rod 32 to rotate, since the moving plate 33 is in sliding connection with the rotating rod 32, and the folding and sealing plate 20 is connected with the moving plate 33, so that the rotating rod 32 rotates, and at the same time, the moving plate 33 is driven to move, and then drives the folding and sealing plate 20 to move to the required position, and then the power member stops driving, so as to complete the automatic adjustment of the folding and sealing plate 20, without manual adjustment, which is beneficial to reduce the labor intensity.

[0045] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principle of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection range of the present application.
