Description

Technical Field

[0001] The present application relates to the technical field of packaging cartons, and in particular to a seam pressing device for packaging cartons. Background Art

[0002] In the process of carton manufacturing and packaging, the role of the seam pressing device is crucial. Although the existing seam pressing devices have achieved the pressing of carton seams to a certain extent, there are still some obvious drawbacks. First of all, most of the existing seam pressing devices use mechanical pressing, and the cartons usually need to be fixed on the workbench in cooperation with the clamping mechanism for seam pressing, resulting in the limitation of their working efficiency. Especially when dealing with a large number of cartons, it is necessary to repeatedly clamp and fix them, and the operation is cumbersome, and the problem of low production efficiency is particularly prominent; and during the pressing process, due to the local clamping and positioning of the carton board, if the pressure distribution is uneven or the pressure is too large, it often causes local deformation of the carton board, which in turn affects the quality of the seam pressing.

[0003] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0006] A seam pressing device for packaging cartons includes a workbench, support columns are arranged on both sides of the top of the workbench, a seam pressing table is installed between the two support columns, a guide rail is arranged on the top of one of the support columns, a seam pressing frame is movably arranged in the guide rail, a cylinder is installed on the seam pressing frame, and the output end of the cylinder is connected with a connecting frame, and a seam pressing roller is rotatably installed inside the connecting frame.

[0007] Preferably, a rotary handle is rotatably installed at the top end of one of the support columns, one end of the rotary handle extends into the support column and is fixed with a threaded rod, and a slider adapted to the threaded rod is arranged outside the threaded rod.

[0008] Preferably, positioning frames are rotatably installed in the middle of both sides of the seam pressing table, one of the positioning frames is fixed to the outer wall of the slider, and the other positioning frame extends into the support column and is slidably connected with the support column.

[0009] Preferably, a servo motor is provided on one side of the seam pressing table. The output end of the servo motor penetrates through the inner wall of the positioning frame and is in transmission connection with the seam pressing table. The bottom end of the inner wall of the seam pressing table is integrally welded with a bottom plate.

Detailed Embodiment

[0018] The following further Figures 1 - 3 describes the present application in detail with reference to the

[0019] The embodiment of the present application discloses a seam pressing device for packaging cardboard boxes. Refer to Figures 1 - 2, including a workbench 1, with support columns 2 provided on both sides of the top of the workbench 1. A seam pressing table 4 is installed between the two support columns 2. A rotating handle 6 is rotatably installed at the top end of one of the support columns 2. One end of the rotating handle 6 extends into the support column 2 and is fixed with a threaded rod 5. A slider 16 is provided outside the threaded rod 5. Operating the rotating handle 6 can drive the threaded rod 5 to rotate within the support column 2. Since positioning brackets 17 are rotatably installed in the middle of both sides of the seam pressing table 4, one of the positioning brackets 17 is fixed to the outer wall of the slider 16, and the other positioning bracket 17 extends into the support column 2 and is slidably connected to the support column 2. Therefore, the seam pressing table 4 can be driven to perform lifting adjustment between the two support columns 2.

[0020] Combined Figure 3 As shown, a servo motor 18 is provided on one side of the seam pressing table 4. The output end of the servo motor 18 penetrates the inner wall of the positioning bracket 17 and is in transmission with the seam pressing table 4. The bottom end of the inner wall of the seam pressing table 4 is integrally welded with a bottom plate 15. Therefore, the seam pressing table 4 can be driven to tilt between the two support columns 2, thus facilitating the unloading of the inner cardboard. Since the bottom plate 15 is composed of multiple pieces, and there are gaps between every two pieces, it is convenient to push the cardboard for unloading through the gaps.

[0021] Furthermore, a guide rail 7 is provided at the top of one of the support columns 2. A reinforcing rod 3 for support is connected between the support column 2 and the guide rail 7. A motor 9 is installed on the outer wall of the guide rail 7. The output end of the motor 9 extends into the guide rail 7 and is in transmission connection with a lead screw 8. A sliding block 10 is slidably provided outside the lead screw 8. The outer wall of the sliding block 10 is connected with a seam pressing frame 11 by screws. Therefore, the seam pressing frame 11 can be driven to perform a linear reciprocating motion, and a cylinder 12 is installed on the seam pressing frame 11. The output end of the cylinder 12 is connected with a connecting frame 13. A seam pressing roller 14 is rotatably installed inside the connecting frame 13. This pneumatic driving method can not only greatly improve the seam pressing efficiency, but also ensure the uniformity of pressure distribution as the seam pressing roller 14 rolls on the surface of the cardboard.

[0022] The implementation principle of a seam pressing device for packaging cartons in an embodiment of this application is as follows: During use, first stack the packaging cardboard neatly and place it into the seam pressing table 4. Then, operate the rotating handle 6 to drive the threaded rod 5 to rotate. Immediately, the slider 16 and the positioning bracket 17 cooperate to slide within the support column 2 to drive the seam pressing table 4 to adjust the seam pressing height. Then, start the cylinder 12 to work and push the connecting frame 13 downward, immediately driving the seam pressing roller 14 to closely adhere to the surface of the cardboard. Then, drive the lead screw 8 to rotate through the motor 9, and push the seam pressing frame 11 to perform a linear reciprocating motion on the surface of the seam pressing table 4 through the sliding block 10, so as to drive the seam pressing roller 14 to roll and press the surface of the cardboard, which can ensure the uniformity of pressure distribution. After the seam pressing is completed, the seam pressing table 4 can also be driven to rotate and turn over by the servo motor 18, which is convenient for unloading the internally pressed cardboard.
