Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing equipment, and more specifically, relates to a carton cross-cutting structure and a carton machine. Background Art

[0002] During the carton processing, the cardboard is mostly cross-cut by a cross-cutting mechanism.

[0026] Please refer to Figures 1 to 5 , and now the carton cross-cutting structure and the carton machine provided by the present invention will be described. The carton cross-cutting structure includes a frame 1, a sliding tool holder 2, a synchronous belt 3, and a cross-cut bottom knife 4. The frame 1 has a horizontally extending cross beam 11. The sliding tool holder 2 is slidably connected to the front side of the cross beam 11. The synchronous belt 3 is rotatably connected to the frame 1 and is used to drive the sliding tool holder 2 to move horizontally along the cross beam 11. The cross-cut bottom knife 4 is connected to the lower part of the frame 1. An upwardly open cavity 41 is provided on the cross-cut bottom knife 4. A cross-cut cutter disc 22 that can extend into the cavity 41 is rotatably connected to the sliding tool holder 2 through a rotating shaft 21. An intermediate pulley 23 that can mesh with the synchronous belt 3 is provided on the outer periphery of the rotating shaft 21. The intermediate pulley 23 can drive the cross-cut cutter disc 22 to rotate circumferentially under the action of the synchronous belt 3 to cut the cardboard.

[0027] Compared with the prior art, the carton cross-cutting structure provided in this embodiment uses the synchronous belt 3 to drive the sliding tool holder 2 to move horizontally along the cross beam 11. At the same time, through the meshing action of the synchronous belt 3 and the intermediate pulley 23, the synchronous belt 3 realizes the rotational drive of the cross-cut cutter disc 22, eliminating the cumbersome need to separately provide a drive mechanism for the cross-cut cutter disc 22. It not only simplifies the structural layout but also reduces the equipment cost, ensures the cross-cutting function of the cross-cut cutter disc 22, and has a good use effect.

[0028] In a possible implementation manner, please refer to Figures 1 to 5 , a horizontally extending sliding guide rail 12 is provided on the cross beam 11. The sliding tool holder 2 is slidably connected to the sliding guide rail 12. The sliding guide rail 12 provided on the cross beam 11 can be slidably matched with the sliding tool holder 2 to effectively guide the sliding direction of the sliding tool holder 2, thereby driving the cross-cut blade to move horizontally and achieving the cutting effect on the cardboard.

[0029] In a possible implementation, please refer to Figures 1 to 5 , two forward and reverse motors 5 are symmetrically arranged on both sides of the frame 1. Driving pulleys 51 are respectively arranged at the output ends of the forward and reverse motors 5. Both ends of the synchronous belt 3 are respectively sleeved on the outer circumferences of the two driving pulleys 51. The synchronous belt 3 can drive the cross-cutting cutter head 22 to rotate and drive the sliding tool holder 2 to move horizontally under the action of the driving pulleys 51.

[0030] In this embodiment, the forward and reverse motors 5 arranged on both sides of the frame 1 are used to synchronously drive the synchronous belt 3 to rotate clockwise or counterclockwise, thereby driving the sliding tool holder 2 and the cross-cutting cutter head 22 to translate synchronously, and simultaneously realizing the rotational movement of the cross-cutting cutter head 22. The arrangement of the forward and reverse motors 5 realizes the dual actions of translation and rotation, simplifies the structural arrangement, and reduces the equipment cost.

[0031] In some embodiments, please refer to Figures 1 to 5 , the rotating shaft 21 is rotatably connected to the rear side of the sliding tool holder 2. The intermediate pulley 23 is located between the cross-cutting cutter head 22 and the sliding tool holder 2. The intermediate pulley 23 protrudes downward from the driving pulley 51. The synchronous belt 3 is a double-sided belt, and the lower layer belt 32 of the synchronous belt 3 is wound around the upper outer circumference of the intermediate pulley 23.

[0032] In this embodiment, the rotating shaft 21 is rotatably connected to the rear side of the transverse moving tool holder. The transverse moving tool holder can block the front sides of the rotating shaft 21 and the cross-cutting cutter head 22, which can not only prevent the cross-cutting cutter head 22 from interfering with other components in position, but also improve the external aesthetics of the structure.

[0033] Further, the synchronous belt 3 is a double-sided belt. The lower layer belt 32 of the synchronous belt 3 is sleeved on the upper outer circumference of the intermediate pulley 23. Both ends of the synchronous belt 3 are respectively sleeved on the outer circumferences of the two driving pulleys 51 in one-to-one correspondence. Under the synchronous driving action of the two driving pulleys 51, the translation driving requirement of the sliding tool holder 2 and the rotational driving action of the cross-cutting cutter head 22 are satisfied. At the same time, the lower layer belt 32 of the synchronous belt 3 can be engaged with the upper outer circumference of the intermediate pulley 23. Both the inner and outer circumferential surfaces of the synchronous belt 3 have tooth shapes, which can meet the driving requirements of the above two actions.

[0034] The intermediate pulley 23 protrudes downward from the driving pulley 51, which can realize the tensioning effect on the synchronous belt 3, enable the synchronous belt 3 to be effectively engaged with the intermediate pulley 23, ensure the driving effect of the synchronous belt 3 on the intermediate pulley 23, and realize the effective cross-cutting of the cardboard.

[0035] In a possible implementation, please refer to Figures 1 to 5 , two pressing wheels 24 are rotatably connected to the sliding tool holder 2.

The pressing wheels 24 are used to press the lower layer belt 32 of the synchronous belt 3 so that the lower layer belt 32 of the synchronous belt 3 is engaged with the intermediate pulley 23.

[0036] In this embodiment, the two downward pressing wheels 24 on the sliding tool holder 2 can press down on the parts of the synchronous belt 3 on both sides of the middle pulley 23, so that the synchronous belt 3 is effectively engaged with the middle pulley 23, meeting the rotational driving effect of the synchronous belt 3 on the transverse cutting tool disc 22. The middle pulley 23 is located at the rear side of the sliding tool holder 2, and the transverse cutting tool disc 22 is located at the rear side of the middle pulley 23. The transverse moving tool disc can drive the transverse cutting tool disc 22 to rotate under the driving action of the synchronous belt 3 to realize the transverse cutting of the cardboard.

[0037] In some embodiments, please refer to Figures 1 to 5 , a horizontally extending toothed bar 25 is provided at the rear side of the sliding tool holder 2. The toothed bar 25 is located above the synchronous belt 3 and meshes with the upper belt 31 of the synchronous belt 3. The sliding tool holder 2 is also provided with a toothed bar 25. The toothed bar 25 is located above the rotating shaft 21 and can be effectively engaged with the upper belt 31 of the synchronous belt 3 to ensure the stability of the moving speed of the synchronous belt 3.

[0038] In a possible implementation manner, please refer to Figures 1 to 5 , the cardboard transverse cutting structure further includes a paper pressing assembly 6. The paper pressing assembly 6 includes a rubber shaft 61 rotatably connected to the machine frame 1 and a plurality of sun gears 62 rotatably connected to the cross beam 11. The rubber shaft 61 is located at the rear side of the transverse cutting bottom knife 4, and the sun gears 62 are located above the rubber shaft 61. A gap for the cardboard to pass through is formed between the rubber shaft 61 and the sun gears 62. The plurality of sun gears 62 are arranged at intervals along the circumferential direction of the rubber shaft 61.

[0039] In this embodiment, the pressing assembly uses the sun gears 62 and the rubber shaft 61 to cooperate with each other to effectively press the cardboard, ensuring the stability of the placement state of the cardboard and meeting the cutting effect of the subsequent rotating tool disc on the cardboard. The transverse cutting bottom knife 4 is located below the transverse cutting tool disc 22, and the transverse cutting tool disc 22 can extend into the cavity 41 of the transverse cutting bottom knife 4 to effectively cut the cardboard, ensuring the effective cutting and separation of the cardboard.

[0040] In some embodiments, please refer to Figures 1 to 5 , a telescopic driving member 7 extending downward is further provided on the cross beam 11. The lower end of the telescopic driving member 7 is connected with a mounting seat 71, and the two sides of the same mounting seat 71 are respectively rotatably connected with sun gears 62.

At the same time, it can also meet the setting requirements of different pressure values, expanding the use range of the equipment.
