TECHNICAL FIELD

[0001] The utility model belongs to the field of packing and sealing box, especially a kind of automatic sealing box device. BACKGROUND

[0002] In the process of folding and sealing the cover plate of the box body, the four cover plates need to be folded first, and in the folding process, two opposite cover plates need to be folded first, then the other two cover plates are folded, and the first folded cover plate is pressed below the second folded cover plate, and after folding, the edge needs to be sealed by adhesive tape, and the cover plate needs to be pressed before sealing, but in the actual folding process, it is inconvenient to adjust the pressing member, and when the thickness of the cover plate is thin, it is easy to cause insufficient pressing degree of the folded cover plate. SUMMARY

[0003] Therefore, the utility model aims at providing an automatic sealing box device to solve the technical problem of inconvenient adjustment of the pressing member in the actual folding process, and easy to cause insufficient pressing degree of the folded cover plate when the thickness of the cover plate is thin.

[0004] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0005] An automatic sealing box device comprises a supporting frame and two symmetrical belt conveying assemblies, the supporting frame is rotatably connected with a plurality of supporting rollers, further comprising: a mounting frame, the mounting frame comprises a positioning seat and a mounting cavity, the positioning seat is fixedly connected to the surface of the supporting frame, and the mounting cavity is fixedly connected to the end of the positioning seat; a turnover claw is rotatably connected inside the mounting cavity, and a surface is rotatably connected with a cylinder, one end of the cylinder away from the turnover claw is rotatably connected to the inner side wall of the mounting cavity; a guide plate is arranged on the bottom surface of the mounting cavity, and the end of the guide plate has an arc-shaped guide surface; two guide rods are arranged below the positioning seat, and the two guide rods each comprise a horizontal pressing rod and a guide inclined rod, and the two guide inclined rods are distributed in an eight-character shape; a threaded adjusting assembly is arranged between the two guide rods and the positioning seat, and the threaded adjusting assembly is used to adjust the height of the two guide rods.

[0006] Specifically, the top of the supporting frame has a mounting channel, and a plurality of supporting rollers are rotatably connected in the mounting channel.

[0007] It should be understood that during the box sealing process, the two belt conveyor assemblies will synchronously convey the box body placed on the supporting rollers, and the arc-shaped guiding surface of the guide plate will first press one of the two cover plates in the first direction of the box body, and then the cylinder will pull the flip claw to flip the flip claw to push and fold the other cover plate in the first direction, so that the cover plates in the first direction of the box body that continues to move can all be squeezed by the guiding inclined surface of the guide plate, and the cover plates in the first direction are folded and maintained. When the box body continues to move, the guide plate continues to press and maintain, and in the process of the guide plate maintaining the folded state of the cover plates in the first direction, the guide rod will further push and fold the two cover plates in the second direction, and the cover plates in the second direction will block the two folded cover plates in the first direction until the two cover plates in the second direction move to the bottom of the horizontal pressure bar and are pressed, thus preparing for the subsequent tape sealing;

[0008] It should be further explained that when the pressure on the cover is insufficient, the two guide rods are adjusted downward through the threaded adjustment assembly to lower the height, thereby tightening the folding cover on the top of the box that is moved below the horizontal pressure rod, providing favorable conditions for subsequent tape sealing.

[0009] Furthermore, the guide oblique rod includes a first end and a second end, and the guide oblique rod gradually decreases in height from the first end to the second end. It should be understood that by providing two guide rods, the cover plate moving in the second direction can be squeezed, and the cover plate in the second direction can be squeezed, flipped and folded.

[0010] Furthermore, the tops of the two horizontal pressure rods are fixedly connected with support bases, which are plugged into the bottoms of the positioning bases. By providing the support bases, the two guide rods are supported.

[0011] Furthermore, the surface of the positioning seat is provided with a plug-in slot, into which a plug-in plate is inserted, and the plug-in plate is fixedly connected to the top of the support seat. It should be understood that the plug-in plate is plugged into the plug-in slot to provide sliding support for the support seat and the guide rod as a whole, restricting the guide rod to vertical movement only at the bottom of the positioning seat.

[0012] Furthermore, the thread adjustment assembly includes:

[0013] Threaded rod, the bottom end of the threaded rod is rotationally connected with a gas spring, the bottom end of the gas spring is rotationally connected on the support base, a moving screw sleeve is fixedly connected on the surface of the positioning base, and the threaded rod is threadedly connected with the moving screw sleeve.

[0014] It should be understood that when the compression degree needs to be adjusted, the threaded rod is rotated, the threaded rod moves under the action of the thread, the support base and the guide rod as a whole are adjusted in height, the height of the guide rod is lowered, and the compression degree of the folded state of the cover plate can be improved, and the height of the guide rod is increased, and the compression degree of the folded state of the cover plate can be reduced.

[0015] Compared with the prior art, the automatic box sealing device has the following beneficial effects:

[0016] (1) The automatic box sealing device maintains the state of the cover plate folded in the first direction, and the guide rod further pushes and folds the two cover plates in the second direction, the cover plates in the second direction shield the two cover plates in the first direction, until the two cover plates in the second direction move below the horizontal pressing rod, the two cover plates in the second direction are pressed, and the preparation for the later tape sealing is made, and the two guide rods are adjusted downward by the threaded adjusting assembly, the height is lowered, the folded cover plates on the top of the box body below the horizontal pressing rod are tightly pressed, and favorable conditions are provided for the later tape sealing.

[0017] (2) The automatic box sealing device is provided with a gas spring, so that the guide inclined rod can compress and be tightly squeezed when the guide inclined rod compresses the cover plate in the second direction, on the one hand, the folded cover plate can have a moving allowance, and on the other hand, the folded state of the cover plate can be maintained.
