Description

Technical Field

[0002] In the prior art, carton sealing machines can generally only seal boxes of one size or specification. When boxes of different sizes or specifications need to be sealed, the carton sealing machine needs to be replaced, which not only makes the sealing efficiency low, but also increases the equipment cost. For some carton sealing machines that can adjust the sealing size, although they have a wider range of practicality and improve the sealing efficiency to a certain extent, since they are all manually operated to adjust the sealing size of the carton sealing machine, not only the efficiency is low, but also the adjustment accuracy is not high enough, and the box packaging is often unqualified due to size errors. In addition, manually adjusting the sealing size of the carton sealing machine will cause the carton sealing machine to interrupt operation, and then cause the interruption of the assembly line, which will also greatly reduce the sealing efficiency.

[0021] The present invention is further described in conjunction with the following examples.

[0022] The present invention provides a variable amplitude switching high-efficiency carton sealing machine, such as Figure 1 and Figure 2 As shown, its structure includes a frame 1 and a conveying mechanism 12 installed on the frame 1 for conveying a box 13, and the conveying mechanism 12 is a conveyor belt composed of rollers. A clamping device for clamping the box 13 conveyed in place is installed on the frame 1, and the clamping device is electrically connected to the main controller. The clamping device includes a clamping block 2 for clamping the outer wall of the box 13 and a first driver for driving the clamping block 2 to move. The first driver includes a slide bar 3 and a first drive motor, and the first drive motor drives the corresponding clamping block 2 to move along the slide bar 3 so that the clamping block 2 clamps the box 13 or releases the box 13. The clamping blocks 2 are located on both sides of the conveying direction of the box 13, and the clamping blocks 2 located on both sides of the box 13 move relatively at the same time to clamp the box 13 and then clamp the box body. When it is necessary to package the splicing board located at the top opening or the bottom opening of the box 13, the clamping blocks 2 located on both sides of the box 13 need to move relatively at the same time to clamp the box 13, so that the box 13 can be fixed, which is convenient for packaging operations. The clamping block 2 is provided with a side sensor that can sense the distance between the clamping block 2 and the outer wall of the box 13 in real time. The side sensor feeds data back to the main controller, and then the main controller can adjust the moving distance of the clamping block 2 according to boxes 13 of different widths, and then the clamping block 2 can hold boxes 13 of different widths, so that boxes 13 of different sizes can be packaged.

[0023] like Figure 1As shown, a packaging mechanism for packaging the splicing plate located at the top opening of the box 13 is installed on the frame 1, and the packaging mechanism is electrically connected to the main control. The packaging mechanism includes a folding device for pushing the splicing plate to fold and splice and a sealing device for sealing the joints between the splicing plates; the packaging mechanism includes a packaging frame 4 and a second driver driving the packaging frame 4 to move vertically, the second driver includes a gear 5, a second driving motor driving the gear 5 to rotate, and a rack 6 meshing with the gear 5, the rack 6 is fixed to the frame 1, the second driving motor is fixed to the packaging frame 4, the gear 5 rotates to make it move along the rack 6, thereby driving the packaging frame 4 to move up and down along the rack 6. The folding device and the sealing device are both installed on the packaging frame 4, and the folding device and the sealing device both move up and down along the rack 6 with the packaging frame 4. The frame 1 is provided with a guide sleeve 8, and the packaging frame 4 is provided with a guide column 7, the guide column 7 is inserted into the guide sleeve 8 and can slide therein, so that the vertical movement of the packaging frame 4 is more stable.

[0024] like Figure 1 As shown, the folding device includes a push plate 10 for pushing the splicing board to fold and a driving cylinder 9 that can drive the push plate 10 to rotate and then push the splicing board to fold. The push plate 10 is provided with a first top sensor that can sense the distance between the push plate 10 and the top of the box 13 in real time. In this way, for boxes 13 of different heights, the first top sensor feeds back the measured data to the main controller, and then the main controller adjusts the position of the packaging rack 4 for boxes 13 of different heights, that is, adjusts the position of the push plate 10, so that the push plate 10 is located at a suitable position, and then drives the cylinder 9 to drive the push plate 10 to rotate and then push the splicing board to fold, thereby realizing the folding and splicing of the splicing boards of boxes 13 of different heights.

[0025] There are four folding devices, which are located around the box body, so as to realize the folding of the splicing panels on the left, right, front and back of the box. The two folding devices located on the left and right sides of the box body work simultaneously, and the two folding devices located on the front and back sides of the box body work simultaneously.

[0026] like Figure 1As shown, the sealing device includes a rotatable sealing rubber wheel 11 for sealing, and the sealing rubber wheel 11 is installed with a tape for sealing the joint of the splicing board. The sealing rubber wheel 11 is provided with a second top sensor that can sense the distance between the sealing rubber wheel 11 and the top of the box 13 in real time. After the splicing board is folded and spliced, the distance between the sealing rubber wheel 11 and the top of the box 13 is sensed in real time by the second top sensor, and then the data is fed back to the main controller, so that the main controller can adjust the position of the packaging frame 4, that is, adjust the position of the sealing rubber wheel 11, so that the sealing rubber wheel 11 reaches a suitable position, and then the clamping device releases the box 13. Since the folding device and the sealing device are arranged in sequence along the conveying direction of the conveying mechanism 12, the box 13 will move forward with the conveying mechanism 12, and the sealing rubber wheel 11 is close to the joint of the splicing board, and then as the box 13 moves, the tape is attached to the splicing line. From the above, it can be seen that the carton sealing machine of the present invention can perform real-time automatic adjustments for boxes 13 of different sizes, so that the carton sealing machine can meet the packaging needs of boxes 13 of various sizes and can switch freely between boxes 13 of various sizes. It is not only highly applicable and flexible, but also has high sealing efficiency.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
