[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] In the relevant technology, paper packaging is the most widely used type of packaging industrial products. Cartons are the most important form of transportation packaging, and paper boxes are widely used as sales packaging for various products such as food, medicine, and electronics.

[0031] Cartons are generally made by folding cardboard, which is provided with creases. The cardboard is folded along the creases to form a carton. Since the creases on the cardboard are prone to cracking when the cardboard is folded, tape is usually applied to the position corresponding to the crease when the cardboard is conveyed. However, when applying the tape, the tape application device tends to lift the cardboard, resulting in an unstable tape application and easily causing the cardboard to shift, resulting in an inaccurate tape application position. To this end, the utility model proposes a cardboard pressing device that can press down the cardboard from above, thereby positioning the cardboard to prevent the cardboard from shifting, which is conducive to improving the accuracy of the tape application position, thereby improving the quality of the carton.

[0032] The first aspect of the present invention provides a cardboard pressing device, such as Figure 1 and Figure 2 As shown, the cardboard pressing device includes a support member 100 and a pressing assembly 200. The pressing assembly 200 includes a pressing member 210 and a connecting member 220. The connecting member 220 is provided with a first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 is connected to the support member 100, and the pressing member 210 is connected to the second connecting portion 222. The connecting member 220 can drive the pressing member 210 to move upward or downward, and the pressing member 210 is suitable for pressing the cardboard 400.

[0033] It should be noted that the connecting member 220 can drive the pressing member 210 to move upward or downward, so that the pressing member 210 can press the cardboard 400, thereby preventing the cardboard 400 from being lifted up by the tape applying device and deflected.

[0034] like Figure 1 As shown, the cardboard 400 is transported by a conveyor 500. The conveyor 500 includes a bracket 520 and a conveyor belt 510. The conveyor belt 510 is installed on the bracket 520 and is suitable for transporting the cardboard 400. Along the conveying direction of the conveyor belt 510, a taping device is provided on the lower side of one end of the conveyor belt 510. After the conveyor belt 510 transports the cardboard 400 to the edge position, the taping device can apply tape to the lower surface of the cardboard 400. When applying tape, the taping device may lift the cardboard 400, causing the cardboard 400 to deviate and the tape application to be unstable. By providing a cardboard pressing device at the edge of the conveyor belt 510 near the taping device, the pressing member 210 is located above the conveyor belt 510, which can press the cardboard 400 from above the cardboard 400, thereby preventing the cardboard 400 from deviating upward.

[0035] It should also be noted that two conveyor devices 500 may be provided, spaced apart along the conveying direction of the conveyor belt 510, and the cardboard 400 can be conveyed from one conveyor device 500 to the other conveyor device 500. The tape applying device is located between the two conveyor devices 500, and when the cardboard 400 is conveyed from one conveyor device 500 to the other conveyor device 500, the tape applying device can apply tape to the lower surface of the cardboard 400.

[0036] It should also be noted that the connecting member 220 can drive the pressing member 210 to move upward or downward, thereby adjusting the pressure applied by the pressing member 210 on the cardboard 400, so that the pressing member 210 can both stably press the cardboard 400 and simultaneously allow the cardboard 400 to be smoothly conveyed by the conveyor belt 510. Furthermore, the connecting member 220 can adjust the upward or downward movement of the pressing member 210, thereby adjusting the gap between the pressing member 210 and the conveyor belt 510 to accommodate cardboards 400 of varying thicknesses, thereby improving the adaptability of the cardboard pressing device.

[0037] The cardboard 400 of the present application may be a cardboard that can be processed into a carton.

[0038] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first connection portion 221 is rotatably connected to the support member 100 , and the second connection portion 222 can rotate around the first connection portion 221 to drive the pressing member 210 to move upward or downward.

[0039] like Figure 2 As shown, it should be noted that the first connecting portion 221 is rotatably connected to the support member 100. The connecting member 220 can be rotated through the first connecting portion 221. The pressing member 210 is connected to the second connecting portion 222, thereby driving the pressing member 210 to rotate, and thus adjusting the height of the pressing member 210, that is, driving the pressing member 210 to move upward or downward.

[0040] For example, the first connection portion 221 is located at one end of the connection member 220 , and the second connection portion 222 may be located at the other opposite end of the connection member 220 .

[0041] It should also be noted that the first connecting portion 221 and the support member 100 can be rotatably connected via components such as a rotating bearing to improve the smoothness of the rotation of the connecting member 220. For example, the connecting member 220 can be a connecting plate, and the support member 100 can be a support plate. A rotating shaft is sequentially provided through the support plate and the connecting plate, thereby rotatably connecting the connecting plate to the support plate. Of course, the specific structure and connection structure of the connecting member 220 and the support member 100 can be determined by those skilled in the art based on actual circumstances and are not specifically limited here.

[0042] It should also be noted that the connecting member 220 can also be slidably connected to the supporting member 100 , and the connecting member 220 can slide upward or downward to adjust the height of the pressing member 210 .

[0043] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the cardboard pressing device further includes a driving member 300 , and the driving member 300 is transmission-connected to the connecting member 220 to drive the connecting member 220 to move upward or downward.

[0044] It should be noted that the cardboard pressing device further includes a driving member 300, which can drive the connecting member 220 to adjust the height of the pressing member 210. By providing the driving member 300, the degree of automation of the cardboard pressing device can be improved.

[0045] For example, when the connecting member 220 is rotatably connected to the supporting member 100 , the driving member 300 can drive the connecting member 220 to rotate. Or when the connecting member 220 is slidably connected to the supporting member 100 , the driving member 300 can drive the connecting member 220 to slide along the supporting member 100 .

[0046] According to some embodiments of the present invention, Figure 2 As shown, the connecting member 220 is further provided with a third connecting portion 223 , and the cardboard pressing device further includes a driving member 300 , the output end of the driving member 300 is rotatably connected to the third connecting portion 223 , and the driving member 300 can push the connecting member 220 to rotate.

The first connection portion 221 is rotatably connected to the support member 100, and the output end of the driving member 300 is rotatably connected to the third connection portion 223, so that the driving member 300 can drive the connecting member 220 to rotate.

[0048] According to some embodiments of the present invention, Figure 2 As shown, the driving member 300 is rotatably connected to the supporting member 100 at a side away from the output end.

[0049] like Figure 2As shown, it should be noted that the driving member 300 can be a cylinder, and the output end of the cylinder is a piston rod, which is rotatably connected to the third connecting portion 223. The outer shell of the cylinder body is rotatably connected to the support member 100. When the piston rod extends, it can push the second connecting portion 222 to rotate upward, and when the piston rod shortens, it can pull the second connecting portion 222 to rotate downward.

[0050] It should also be noted that the driving member 300 may also be a linear motor or other device. Those skilled in the art may determine it according to actual conditions, and no specific limitation is made here.

[0051] According to some embodiments of the present invention, the pressing member 210 is rotatably connected to the second connecting portion 222 .

[0052] It should be noted that the pressing member 210 is rotatably connected to the second connecting portion 222.

[0054] like Figure 1 and Figure 2 As shown, it should be noted that the lower pressing member 210 includes a rotating shaft 211 and a rotating wheel 212. The rotating wheel 212 is rotatably connected to the rotating shaft 211. The rotating shaft 211 is connected to the second connecting portion 222 along its axial end. The radial sidewall of the rotating wheel 212 can contact the surface of the cardboard 400 to press the cardboard 400. By providing the rotating wheel 212 to press the cardboard 400, the horizontal friction between the cardboard 400 and the lower pressing member 210 is reduced, facilitating smooth movement of the cardboard 400.

[0055] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, there are multiple rotating wheels 212 , and the multiple rotating wheels 212 are sleeved on the rotating shaft 211 at intervals along the axial direction of the rotating shaft 211 .
