Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box processing technology, and in particular to a secondary creasing and folding mechanism for corrugated cardboard boxes. Background Technology

[0002] Corrugated box creases are created on corrugated cardboard during the production process, using a crease-pressing technique to allow for subsequent folding into boxes. Creases are a crucial step in box forming, directly affecting the box's strength and appearance. Secondary creases involve re-crease the cardboard after the first crease during production to further optimize the precision and strength of the creases.

[0003] Different corrugated boxes require different finishing processes, so the distance between the upper and lower creasing rollers needs to be adjusted during creasing. Otherwise, creasing problems may occur. Also, after the first creasing, a second creasing is performed, and the crease spacing in the horizontal direction needs to be adjusted. Otherwise, the second creasing work cannot be completed. Utility Model Content

[0004] The problem solved by this utility model is to provide a secondary creasing and folding mechanism for corrugated cardboard boxes. This mechanism addresses the issue that different corrugated cardboard boxes require different post-processing methods, necessitating adjustments to the spacing between the upper and lower creasing rollers during creasing to prevent creasing problems. Additionally, it addresses the technical problem of adjusting the horizontal crease spacing after the first creasing step to ensure the completion of the secondary creasing process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A secondary creasing and folding mechanism for corrugated cardboard boxes includes a base with two rod seats symmetrically and slidably mounted on the base. A first rotating shaft is rotatably mounted on the inner side of each of the two rod seats, and a bottom creasing wheel is mounted on the first rotating shaft. A first polygonal rotating shaft is slidably mounted between the two first rotating shafts. A sliding groove is provided on each of the two rod seats, and an adjusting block is slidably mounted within the sliding groove. A second rotating shaft is rotatably mounted on the inner side of each of the two adjusting blocks, and a top creasing wheel is mounted on the second rotating shaft. A second polygonal rotating shaft is slidably mounted between each top creasing wheel.

[0007] Preferably, guide rails are symmetrically installed on the top side of the base, and the slide moves along the guide rails.

[0008] Preferably, a rod seat is installed at both ends of the base, and a first motor is installed on one of the rod seats. A threaded rod is installed at the output end of the first motor between the two rod seats. The threads at both ends of the threaded rod are in opposite directions, and the two threaded rods are respectively threadedly connected to two slides.

[0009] Preferably, a second motor is mounted on the slide, and the output end of the second motor is connected to one of the first rotating shafts.

[0010] Preferably, each of the two ends of the first rotating shaft is provided with a first polygonal groove, and the ends of the first polygonal rotating shafts are located within the first polygonal grooves.

[0011] Preferably, a threaded handle is threaded through the top of the slide block, and the bottom of the threaded handle is connected to the adjusting block via a bearing. A slide rail is provided inside the slide groove.

[0012] Preferably, each of the two ends of the second rotating shaft is provided with a second polygonal groove, and the ends of the second polygonal rotating shafts are located within the second polygonal grooves.

[0013] The beneficial effects of this utility model are: the first motor drives the threaded rod to rotate, which in turn drives the threaded sliding block to move along the guide rail, adjusting the distance between the two sliding blocks, that is, adjusting the distance between the two bottom pressure rollers and the two top pressure rollers, which is convenient to flexibly adjust according to the specific pressure line distance of the corrugated carton.

[0014] Rotating the threaded throttle causes the adjusting block to rise and fall within the chute, adjusting the distance between the bottom and top pressure rollers to facilitate the pressure work on corrugated boxes of different thicknesses. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figure 1 and Figure 2 A secondary creasing and folding mechanism for corrugated cardboard boxes includes a base 1, on which two rod seats 2 are symmetrically and slidably mounted. A first rotating shaft 7 is rotatably mounted on the inner side of each rod seat 2. A bottom creasing wheel 8 is mounted on the first rotating shaft 7. A first polygonal rotating shaft 10 is slidably mounted between the two first rotating shafts 7. A sliding groove 12 is provided on each of the two rod seats 2. An adjusting block 13 is slidably mounted in the sliding groove 12. A second rotating shaft 15 is rotatably mounted on the inner side of each of the two adjusting blocks 13. A top creasing wheel 16 is mounted on the second rotating shaft 15, and a second polygonal rotating shaft 18 is slidably mounted between each top creasing wheel 16.

[0022] The base 1 is symmetrically equipped with guide rails 4 on its top side, and the slide 6 moves along the guide rails 4. Both ends of the base 1 are equipped with rod seats 2. One rod seat 2 is equipped with a first motor 5. The output end of the first motor 5 is located between the two rod seats 2 and a threaded rod 3 is installed. The two ends of the threaded rod 3 have opposite thread directions, and the two threaded rods 3 are respectively threadedly connected to the two slides 6. The first motor 5 drives the threaded rod 3 to rotate, which in turn drives the threaded slide 6 to move along the guide rails 4, adjusting the distance between the two slides 6.

[0023] A second motor 11 is installed on the slide 6, and the output end of the second motor 11 is connected to one of the first rotating shafts 7. The second motor 11 drives the first rotating shaft 7 and the bottom pressure roller 8 to rotate, and performs the pressure operation on the corrugated carton passing between the bottom pressure roller 8 and the top pressure roller 16.

[0024] Both first rotating shafts 7 have first polygonal grooves 9 at their ends, and the end of the first polygonal rotating shaft 10 is located in the first polygonal groove 9. A threaded handle 14 is threaded through the top of the slide block 6, and the bottom end of the threaded handle 14 is connected to the adjusting block 13 through a bearing. A slide rail is provided in the slide groove 12. Both second rotating shafts 15 have second polygonal grooves 17 at their ends, and the end of the second polygonal rotating shaft 18 is located in the second polygonal groove 17. During the movement of the slide block 6, the first rotating shaft 7 moves along the first polygonal rotating shaft 10, bringing the first polygonal rotating shaft 10 into the first polygonal groove 9, and the second rotating shaft 15 moves along the second polygonal rotating shaft 18, bringing the second polygonal rotating shaft 18 into the second polygonal groove 17. At the same time, by rotating the threaded handle 14, the adjusting block 13 is driven to rise and fall in the slide groove 12, adjusting the distance between the bottom pressure roller 8 and the top pressure roller 16.

[0025] The first motor 5 drives the threaded rod 3 to rotate, which in turn drives the threaded sliding block 6 to move along the guide rail 4. Adjusting the distance between the two sliding blocks 6, that is, adjusting the distance between the two bottom pressure rollers 8 and the two top pressure rollers 16, makes it easy to flexibly adjust according to the specific pressure spacing of the corrugated carton.

[0026] Rotating the threaded throttle 14 causes the adjusting block 13 to rise and fall within the slide groove 12, adjusting the distance between the bottom pressure roller 8 and the top pressure roller 16 to facilitate the pressure work of corrugated boxes of different thicknesses.
