[0002] For example, Chinese patent CN221641915U discloses a cardboard box creasing device for cardboard box production. Two fixed blocks move outside two threaded rods to move two support plates away from each other, which is convenient to adjust according to the required size of different cardboard boxes. By rotating the fastening bolt, the limiting plate is lowered to limit and fix the cardboard box to prevent displacement during creasing. The electric telescopic rod extends to lower the pressure plate and fits it with the top edge of the support plate to creasing the cardboard box.

[0003] The carton creasing device in the above application limits and fixes the carton from the side by a support plate, and then creasing the carton by a pressure plate. Its operation is cumbersome and the creasing efficiency is low. Moreover, when dealing with cartons of different thicknesses, the pressure plate is driven down by an electric telescopic rod to creasing, which makes the position and pressure of the pressure plate not stable enough, thus making it difficult to maintain the same depth and clarity of the creasing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic creasing and forming device for carton production, which solves the technical problems of cumbersome operation, low creasing efficiency, and difficulty in maintaining consistent creasing depth and clarity in existing technologies, thereby achieving the goal of improving creasing efficiency and creasing consistency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic creasing and forming device for carton production, including an operating table installed on a creasing machine, the creasing machine being provided with a creasing mechanism for uniformly applying pressure to the carton, and the operating table being provided with an automatic feeding mechanism for conveying the carton.

[0006] The indentation mechanism includes a rotating shaft rotatably connected to a rotating hole in the indentation machine, and multiple indentation rollers are arrayed on the rotating shaft. A material support roller is rotatably connected to the rotating hole in the indentation machine, and a drive motor for driving the rotating shaft to rotate is installed on the indentation machine. The indentation machine is equipped with an adjustment component for adjusting the height of the rotating shaft.

[0007] Preferably, the material support roller is located directly below the rotating shaft and is flush with the operating table. The indentation roller is sleeved on the rotating shaft, and a locking slider that slides left and right on the rotating shaft is installed on the side of the indentation roller. Locking bolts are threaded into the threaded holes on the upper and lower sides of the locking slider.

[0008] Preferably, the adjusting component includes a strip groove formed on the indentation machine, and an electric lifting rod is installed on the top wall of the strip groove. A bearing seat is installed at the bottom free end of the electric lifting rod, the rotating shaft is rotatably connected to the bearing seat, and the drive motor is installed on the bearing seat.

[0009] Preferably, the feeding mechanism includes feeding rollers rotatably connected to a rotating hole on the creasing machine and located in a slot on the operating table, with rubber sleeves fitted on both feeding rollers. Each feeding roller has a pulley installed at its right end, and a transmission belt connects the two pulleys. The creasing machine is equipped with a feeding motor that drives the pulleys to rotate, and the operating table is provided with a limiting component for limiting and fixing cartons of different sizes.

[0010] Preferably, the limiting component includes a bidirectional motor installed at the center of the bottom of the operating table, and the output ends of the bidirectional motor are connected to lead screws.

[0012] By means of the above technical solution, this utility model provides an automatic creasing and forming device for carton production, which has at least the following beneficial effects:

[0013] 1. This utility model uses a drive motor to rotate a rotating shaft, which in turn rotates the creasing rollers on the rotating shaft, thereby uniformly creasing the cartons passing through the support rollers. Since the distance between the creasing rollers and the support rollers remains constant, the consistency of the creasing is ensured.

[0014] 2. This utility model involves unscrewing the locking bolt, then pulling the locking slider to move the creasing roller on the rotating shaft to the desired position, and then screwing the locking bolt back into the locking slider until it abuts the rotating shaft, thereby completing the position fixation. This adapts to creasing work on cartons of different sizes and improves the versatility of the device.

[0015] 3. This utility model uses an electric lifting rod to pull the bearing seat up and down in the strip groove, thereby driving the rotating shaft inside the bearing seat to move up and down, which in turn drives the spacing between the creasing roller and the material support roller to adjust the distance between the rollers to accommodate cartons of different thicknesses, thus improving the applicability of the device.

[0016] 4. This utility model uses a bidirectional motor to drive the lead screw to rotate, which in turn drives the threaded slider on the lead screw to slide along the inner wall of the guide groove, thereby causing the two limiting plates to move relative to each other and limit the carton from both sides, preventing the carton from tilting during transportation and affecting the indentation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Addressing the issues of cumbersome operation, low creasing efficiency, and inconsistent creasing depth and clarity in existing technologies, this embodiment provides an automatic creasing and forming device for carton production. Please refer to... Figures 1-6 This embodiment provides an automatic creasing and forming device for carton production, which can improve creasing efficiency and creasing consistency. The automatic creasing and forming device for carton production includes an operating table 2 mounted on a creasing machine 1. The creasing machine 1 is equipped with a creasing mechanism 3 that applies uniform pressure to the carton. The operating table 2 is equipped with an automatic feeding mechanism 4 for conveying the carton. The feeding mechanism 4 automatically feeds the carton into the creasing mechanism 3 for rapid creasing processing, while maintaining creasing consistency for cartons of the same thickness and specifications.

[0035] Because existing technologies are cumbersome to operate, have low creasing efficiency, and struggle to maintain consistent creasing depth and clarity, this device is equipped with a creasing mechanism 3. The creasing mechanism 3 includes a rotating shaft 31 rotatably connected to a rotating hole in the creasing machine 1, with multiple creasing rollers 32 arrayed on the rotating shaft 31. A material support roller 33 is rotatably connected to the rotating hole in the creasing machine 1, and a drive motor 34 is installed on the creasing machine 1 to drive the rotating shaft 31 to rotate. The creasing machine 1 is equipped with a height adjustment component 35 to adjust the height of the rotating shaft 31. Starting the drive motor 34 drives the rotating shaft 31 to rotate, which in turn drives the creasing rollers 32 on the rotating shaft 31 to rotate, thereby uniformly creasing the cartons passing through the material support roller 33. Because the distance between the creasing rollers 32 and the material support roller 33 remains constant, consistent creasing is ensured.

[0036] Since creasing of cartons of different sizes is required during production, the material support roller 33 in this device is located directly below the rotating shaft 31 and is flush with the operating table 2. The creasing roller 32 is sleeved on the rotating shaft 31, and a locking slider 36 that slides left and right on the rotating shaft 31 is installed on the side of the creasing roller 32. The threaded holes on the upper and lower sides of the locking slider 36 are threaded with locking bolts 37. When the position of the creasing roller 32 needs to be adjusted, the locking bolts 37 are unscrewed, and then the locking slider 36 is pulled to move the creasing roller 32 on the rotating shaft 31 to the desired position. Then the locking bolts 37 are screwed into the locking slider 36 again until they abut against the rotating shaft 31, thereby completing the position fixation. This adapts to the creasing of cartons of different sizes and improves the versatility of the device.

[0037] Since creasing of cartons of different thicknesses is required during production, the device is also equipped with a spacing adjustment component 35. The spacing adjustment component 35 includes a strip groove 351 formed on the creasing machine 1, and an electric lifting rod 352 is installed on the top wall of the strip groove 351. A bearing seat 353 is installed at the free end of the bottom of the electric lifting rod 352. The rotating shaft 31 is rotatably connected to the bearing seat 353, and the drive motor 34 is installed on the bearing seat 353. When the electric lifting rod 352 is activated, it pulls the bearing seat 353 to slide up and down in the strip groove 351, thereby driving the rotating shaft 31 in the bearing seat 353 to move up and down, which in turn drives the spacing between the creasing roller 32 and the material support roller 33 to adjust to accommodate cartons of different thicknesses, thereby improving the applicability of the device.

[0038] Because manual feeding is inefficient and poses certain safety hazards, the device also includes a feeding mechanism 4. The feeding mechanism 4 includes feeding rollers 41 rotatably connected to a rotating hole in the embossing machine 1 and located in a slot in the operating table 2. Each feeding roller 41 is fitted with a rubber sleeve 42. A pulley 43 is mounted on the right end of each feeding roller 41, and a drive belt 44 connects the two pulleys 43. The embossing machine 1 is equipped with a mechanism to drive the pulleys 43 to rotate. The feeding motor 45 and the operating table 2 are equipped with a limiting component 46 for limiting and fixing cartons of different sizes. When the feeding motor 45 is started, the pulley 43 rotates, which in turn drives the two feeding rollers 41 to rotate through the transmission belt 44. At this time, the cartons are placed flat on the feeding rollers 41 and the cartons are automatically fed into the space between the support roller 33 and the creasing roller 32 for creasing. The rubber sleeve 42 increases the friction with the cartons and prevents the feeding rollers 41 from spinning idly and failing to feed the cartons.

[0039] The control panel 2 is equipped with a controller 5. The indentation mechanism 3 and the feeding mechanism 4 are both electrically connected to the controller 5, and the operation of the device is controlled by the controller 5.

[0040] Example 2

[0041] Because the carton may become skewed during transport, affecting the creasing trajectory, therefore, based on Example 1, as follows... Figures 1-6 As shown, the device is also equipped with a limiting component 46. The limiting component 46 includes a bidirectional motor 461 installed at the center of the bottom of the operating table 2. The output ends of the bidirectional motor 461 are connected to lead screws 462. The lead screws 462 are threadedly connected to threaded sliders 463 that slide left and right on the inner wall of the guide groove opened on the operating table 2. The top of the threaded sliders 463 is equipped with limiting plates 464. When the bidirectional motor 461 is started, it drives the lead screws 462 to rotate, which in turn drives the threaded sliders 463 on the lead screws 462 to slide along the inner wall of the guide groove. This causes the two limiting plates 464 to move relative to each other, thereby limiting the carton from both sides and preventing the carton from tilting during transportation, which would affect the creasing.
