Technical Field

[0001] This utility model belongs to the field of creasing device technology, and specifically relates to a creasing device for carton manufacturing. Background Technology

[0002] Corrugated cardboard boxes are cartons made from corrugated cardboard through processes such as die-cutting, creasing, stapling, or gluing. They are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. For over half a century, corrugated cardboard boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. The creasing device in cardboard box manufacturing is used to create predetermined fold lines on the cardboard (including corrugated cardboard), making the positioning more stable and the forming more standardized during subsequent slotting, folding, and box assembly processes. However, in existing technologies, the creasing operation of corrugated cardboard relies heavily on manual feeding, requiring operators to manually align each sheet of corrugated cardboard with the pressure roller before feeding it in, increasing the workload of the operators. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a cardboard box manufacturing creasing device that uses an automatic feeding device for stable automatic feeding. The operator only needs to refill the feeding hopper after all the cardboard has been fed out. Compared with the manual feeding method of feeding cardboard one by one, this effectively reduces the workload of the operator.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cardboard box manufacturing creasing device, comprising a creasing conveying channel, wherein a creasing roller, a first conveying roller, and a second conveying roller are rotatably mounted on the inner side of the creasing conveying channel; a roller gap adjustment mechanism is provided on both side walls of the creasing conveying channel; the creasing roller, the first conveying roller, and the second conveying roller are rotatably mounted on the inner side of the roller gap adjustment mechanism; a first transmission mechanism is provided on the side of the creasing conveying channel and at one end of the creasing roller, the first conveying roller, and the second conveying roller connected to the creasing conveying channel; the creasing conveying channel... The feed end is connected to an automatic feeding device, which includes a feeding hopper fixed to the feed end of the indentation conveying channel. One end of the feeding hopper is provided with a feeding groove, and one end of the feeding hopper is provided with a feeding groove adjustment mechanism. A roller mounting roller is installed through and rotatably on the bottom plate of the feeding hopper. A roller is sleeved on the outer side of the roller mounting roller. A second transmission mechanism is installed on one end of the roller mounting roller and the side of the feeding hopper. A slide rail is embedded in the inner side of the feeding hopper. A gravity pressing frame is slidably installed on the inner side of the slide rail. A handle is installed on the side of the gravity pressing frame.

[0005] The beneficial effects of this utility model are as follows: This device can achieve stable automatic feeding, improve the automation level of the cardboard creasing device, and the operator only needs to refill after all the cardboard in the feeding hopper has been fed out. Compared with the manual feeding method of feeding cardboard one by one, it effectively reduces the workload of the operator.

[0006] To adjust the roller gap:

[0007] As a further improvement to the above technical solution: the roller gap adjustment mechanism includes roller gap adjustment grooves that pass through the side walls on both sides of the indentation conveying channel. A roller gap adjustment slider is slidably installed on the inner side of the roller gap adjustment groove. One side of the roller gap adjustment slider is rotatably connected to a first screw. The first screw passes through the outer side of the indentation conveying channel and is threadedly connected to the indentation conveying channel.

[0008] The beneficial effect of this improvement is that by rotating the first screw through the knob at one end of the first screw, the roller gap adjustment slider can be driven to slide along the roller gap adjustment groove through the transmission between the first screw and the indentation conveying channel, thereby achieving the function of adjusting the roller gap.

[0009] To adjust the height of the feed trough opening through which the cardboard can pass:

[0010] As a further improvement to the above technical solution: the feeding trough adjustment mechanism includes an adjustment trough disposed at the connection between the feeding hopper and the indentation conveying channel. A trough height adjustment plate is slidably installed inside the adjustment trough. One end of the adjustment trough passes through and is threadedly connected to a second screw. One end of the second screw is rotatably connected to the trough height adjustment plate.

[0011] The beneficial effects of this improvement are as follows: by rotating the second screw through the knob at one end of the second screw, the groove height adjustment plate can be slid along the adjustment groove through the transmission between the second screw and the adjustment groove, thereby adjusting the groove height of the feeding groove that allows the cardboard to pass through.

[0012] To facilitate the rotation of the first and second screws:

[0013] As a further improvement to the above technical solution: a knob is connected to one end of the first screw and one end of the second screw.

[0014] The beneficial effect of this improvement is that the knob setting allows the operator to rotate the first and second screws without the aid of tools.

[0015] To quickly confirm the adjustment distance:

[0016] As a further improvement to the above technical solution: scale lines are provided on the side of the indentation conveying channel and the side of the groove height adjustment plate.

[0017] The beneficial effects of this improvement are: the scale lines provide a direct reading reference for setting the roller gap and adjusting the groove height; the operator can quickly adjust the paperboard quota parameters by directly aligning the scale with the scale.

[0018] To improve feed reliability:

[0019] As a further improvement to the above technical solution: the roller is made of rubber.

[0020] The beneficial effects of this improvement are: the rubber roller, driven by the roller mounting roller, forms a high-friction, low-damage driving interface with the cardboard, which can provide stable traction without scratching the surface, improve feeding reliability, and reduce noise and vibration.

[0021] To ensure stable gear meshing during fine adjustments to the roll gap or load fluctuations:

[0022] As a further improvement to the above technical solution: the gear is a long-tooth gear.

[0023] The beneficial effects of this improvement are: the gears are long-toothed gears, which can maintain stable meshing even when the roller gap is finely adjusted or the load fluctuates, ensuring stable synchronous rotation between the two sets of indentation rollers, between the two sets of first conveying rollers, and between the two sets of second conveying rollers.

[0024] To drive the indentation roller, the first conveyor roller, and the second conveyor roller to rotate:

[0025] As a further improvement to the above technical solution: the first transmission mechanism includes a first motor installed on the side of the indentation conveying channel. The output end of the first motor, the indentation roller connected to the indentation conveying channel, the first conveying roller, and the second conveying roller are all connected to a first pulley. The indentation roller connected to the indentation conveying channel and the first conveying roller, the first conveying roller and the second conveying roller, and the second conveying roller and the output end of the first motor are all connected to the first pulley by a first belt for transmission. Gears are sleeved on the outer sides of the two indentation rollers, the first conveying roller, and the second conveying roller. The gears on the two indentation rollers, the gears on the two first conveying rollers, and the gears on the two second conveying rollers are all meshed.

[0026] The beneficial effects of this improvement are as follows: the first motor drives the first pulley connected to its output end to rotate, and the transmission between the first pulley and the first belt drives the embossing roller, the first conveying roller, and the second conveying roller connected to the embossing conveying channel to rotate synchronously. At the same time, it drives the gear located outside the embossing roller, the first conveying roller, and the second conveying roller to rotate. Through the meshing transmission of the gear, the embossing roller, the first conveying roller, and the second conveying roller located on the roller gap adjustment slider rotate in opposite directions.

[0027] To feed the cardboard into the feed trough:

[0028] As a further improvement to the above technical solution: the second transmission mechanism includes a second pulley connected to one end of the roller mounting roller, a second motor is mounted on the side of the feeding hopper, and the output end of the second motor is also connected to a second pulley. The two adjacent roller mounting rollers and the roller mounting roller closest to the second motor and the output end of the second motor are all connected to the second pulley by the second belt for transmission.

[0029] The beneficial effects of this improvement are as follows: The second motor drives the second pulley connected to it to rotate, and through the transmission of the second pulley and the second belt, it drives each roller mounting roller to rotate synchronously, thereby driving the rollers to rotate. The rollers outside each roller mounting roller rotate at the same speed. Under the downward pressure of the gravity press, the bottom layer of cardboard can form a tight contact with the rollers, thereby forming a stable friction force. At the same time, it avoids the cardboard from arching and being unable to pass smoothly through the feeding trough. The rotating rollers generate high friction and low damage multi-point active traction on the bottom layer of cardboard, feeding the cardboard into the feeding trough in a stable posture.

[0030] To secure the gravity-operated pressure frame:

[0031] As a further improvement to the above technical solution: the side of the slide rail has a through groove, and the side of the gravity pressure frame is provided with a screw hole and a locking bolt is threadedly connected thereto, the locking bolt passing through the through groove.

[0032] The beneficial effects of this improvement are as follows: before filling the feeding hopper with cardboard, after pushing the gravity pressing frame upward to a certain height, it can be locked by tightening the locking bolts, and then the cardboard can be easily filled into the space below the gravity pressing frame.

[0033] In summary, the beneficial effects of this case are as follows:

[0034] 1. This device is equipped with a roller gap adjustment mechanism and a feed trough adjustment mechanism. By rotating the first screw with a knob at one end, the roller gap adjustment slider is driven to slide along the roller gap adjustment groove through the transmission between the first screw and the creasing conveying channel. The adjustment of the roller gap adjustment slider is controlled by the scale lines on the side of the creasing conveying channel, thus confirming the adjusted roller gap. By rotating the second screw with a knob at one end, the groove height adjustment plate is driven to slide along the adjustment groove through the transmission between the second screw and the adjustment groove. The adjustment of the groove height adjustment plate is controlled by the scale lines on the side of the adjustment groove, thus confirming the adjusted groove height of the feed trough. By quickly and accurately adjusting the roller gap and the groove height of the feed trough, it can be applied to creasing work on paperboard of different thicknesses.

[0035] 2. This device is equipped with an automatic feeding system. After a stack of cardboard is filled into the feeding hopper, the bottom layer of cardboard, under the downward pressure of the gravity pressing frame, forms a tight contact with the rollers, creating stable friction. This prevents the cardboard from arching and hindering its smooth passage through the feeding trough. The rotating rollers, driven by a second transmission mechanism, generate high-friction, low-damage multi-point active traction on the bottom layer of cardboard, feeding it into the feeding trough in a stable posture and then into the creasing conveying channel for creasing. Due to the restriction of the trough height adjustment plate, all cardboard except the bottom layer cannot move. After a cardboard sheet is fed into the creasing conveyor channel from inside the feeding hopper, the cardboard above it automatically falls and contacts the rollers. Driven by the rollers, it continues to be fed into the creasing conveyor channel for creasing. As the cardboard is continuously output, the gravity pressing frame automatically slides down the slide rail under the action of gravity, maintaining downward pressure on the cardboard and helping the bottom cardboard to maintain close contact with the rollers, achieving stable automatic feeding. The operator only needs to refill the feeding hopper after all the cardboard has been fed out. Compared with the manual feeding method of one cardboard sheet after another, it effectively reduces the workload of the operator.

[0036] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0045] like Figure 1-6 As shown, a cardboard box manufacturing creasing device includes a creasing conveying channel 1. A creasing roller 21, a first conveying roller 22, and a second conveying roller 23 are rotatably mounted on the inner side of the creasing conveying channel 1. A roller gap adjustment mechanism is provided on both side walls of the creasing conveying channel 1. The creasing roller 21, the first conveying roller 22, and the second conveying roller 23 are rotatably mounted on the inner side of the roller gap adjustment mechanism. A first transmission mechanism is installed on the side of the creasing conveying channel 1 and at one end of the creasing roller 21, the first conveying roller 22, and the second conveying roller 23 connected to the creasing conveying channel 1. An automatic feeding device is connected to the feed end of the creasing conveying channel 1. The device includes a feeding hopper 311 fixed to the feed end of the indentation conveying channel 1. One end of the feeding hopper 311 is provided with a feeding groove 312. One end of the feeding hopper 311 is provided with a feeding groove adjustment mechanism. A roller mounting roller 331 is mounted through and rotatably on the bottom plate of the feeding hopper 311. A roller 332 is sleeved on the outer side of the roller mounting roller 331. A second transmission mechanism is mounted on one end of the roller mounting roller 331 and the side of the feeding hopper 311. A slide rail 341 is embedded in the inner side of the feeding hopper 311. A gravity pressing frame 342 is slidably mounted on the inner side of the slide rail 341. A handle 343 is mounted on the side of the gravity pressing frame 342.

[0046] This device can achieve stable automatic feeding, improve the automation level of the cardboard creasing device. The operator only needs to refill after all the cardboard in the feeding hopper 311 has been fed out. Compared with the manual feeding method of feeding cardboard one by one, it effectively reduces the workload of the operator.

[0047] The roller gap adjustment mechanism includes roller gap adjustment grooves 28 that pass through the side walls of both sides of the indentation conveying channel 1. A roller gap adjustment slider 29 is slidably installed on the inner side of the roller gap adjustment grooves 28. One side of the roller gap adjustment slider 29 is rotatably connected to a first screw 210. The first screw 210 passes through the outer side of the indentation conveying channel 1 and is threadedly connected to the indentation conveying channel 1.

[0048] Rotating the first screw 210 by turning the knob 41 at one end of the first screw 210 will drive the roller gap adjusting slider 29 to slide along the roller gap adjusting groove 28 through the transmission between the first screw 210 and the indentation conveying channel 1, thereby adjusting the roller gap.

[0049] The feeding trough adjustment mechanism includes an adjustment trough 321 located at the connection between the feeding hopper 311 and the indentation conveying channel 1. A trough height adjustment plate 322 is slidably installed inside the adjustment trough 321. One end of the adjustment trough 321 passes through and is threadedly connected to a second screw 323. One end of the second screw 323 is rotatably connected to the trough height adjustment plate 322.

[0050] The second screw 323 is rotated by the knob 41 at one end of the second screw 323. The transmission between the second screw 323 and the adjusting groove 321 drives the groove height adjusting plate 322 to slide along the adjusting groove 321, thereby adjusting the groove height of the feeding groove 312 that allows the cardboard to pass through.

[0051] A knob 41 is connected to one end of the first screw 210 and one end of the second screw 323.

[0052] The knob 41 allows the operator to rotate the first screw 210 and the second screw 323 without the aid of tools.

[0053] Both the side of the indentation conveying channel 1 and the side of the slot height adjustment plate 322 are provided with scale lines 42.

[0054] The scale line 42 provides a direct reading reference for setting the roller gap and adjusting the groove height of the groove 321: the operator can quickly adjust the paperboard quota parameters by directly aligning the scale with the scale.

[0055] The roller 332 is a rubber wheel.

[0056] The rubber roller 332, driven by the roller mounting roller 331, contacts the cardboard to form a high-friction, low-damage driving interface, which can provide stable traction without scratching the surface, improve feeding reliability, and reduce noise and vibration.

[0057] The gear 27 is a long-tooth gear.

[0058] The gear 27 is a long-toothed gear, which can maintain stable meshing even when the roller gap is finely adjusted or the load fluctuates, ensuring stable synchronous rotation between the two sets of indentation rollers 21, between the two sets of first conveying rollers 22, and between the two sets of second conveying rollers 23.

[0059] The first transmission mechanism includes a first motor 26 installed on the side of the indentation conveying channel 1. The output end of the first motor 26, one end of the indentation roller 21 connected to the indentation conveying channel 1, the first conveying roller 22 and the second conveying roller 23 are all connected to a first pulley 24. The indentation roller 21 and the first conveying roller 22 connected to the indentation conveying channel 1, the first conveying roller 22 and the second conveying roller 23, and the second conveying roller 23 and the output end of the first motor 26 are all connected to the first pulley 24 by a first belt 25 for transmission. Gears 27 are sleeved on the outer sides of the two indentation rollers 21, the first conveying roller 22 and the second conveying roller 23. The gears 27 on the two indentation rollers 21, the two first conveying rollers 22 and the two second conveying rollers 23 are all meshed.

[0060] The first motor 26 drives the first pulley 24 connected to its output end to rotate. Through the transmission between the first pulley 24 and the first belt 25, the first conveyor roller 21, the first conveyor roller 22, and the second conveyor roller 23 connected to the indentation conveying channel 1 are driven to rotate synchronously. At the same time, the gear 27 located outside the indentation roller 21, the first conveyor roller 22, and the second conveyor roller 23 are driven to rotate. Through the meshing transmission of the gear 27, the indentation roller 21, the first conveyor roller 22, and the second conveyor roller 23 located on the roller gap adjusting slider 29 are driven to rotate in opposite directions.

[0061] The second transmission mechanism includes a second pulley 333 connected to one end of the roller mounting roller 331. A second motor 335 is mounted on the side of the feeding hopper 311. The output end of the second motor 335 is also connected to a second pulley 333. The two adjacent roller mounting rollers 331 and the roller mounting roller 331 closest to the second motor 335 and the output end of the second motor 335 are all connected to the second pulley 333 by a second belt 334 for transmission.

[0062] The second motor 335 drives the second pulley 333 connected to it to rotate. Through the transmission between the second pulley 333 and the second belt 334, the roller mounting rollers 331 are driven to rotate synchronously, thereby driving the rollers 332 to rotate. The rollers 332 outside each roller mounting roller 331 rotate at the same speed. Under the downward pressure of the gravity press frame 342, the bottom layer of cardboard can form a tight contact with the rollers 332, thereby forming a stable friction force. At the same time, it avoids the cardboard from arching and being unable to pass smoothly through the feeding trough 312. The rotating rollers 332 generate high friction and low damage multi-point active traction on the bottom layer of cardboard, feeding the cardboard into the feeding trough 312 in a stable posture.

[0063] The slide rail 341 has a through groove on its side, and the gravity pressure bracket 342 has a screw hole on its side and a locking bolt 5 is threadedly connected to it. The locking bolt 5 passes through the through groove.

[0064] Before filling the feeding hopper 311 with cardboard, push the gravity pressing frame 342 upward to a certain height, and then lock it by tightening the locking bolt 5. After that, the cardboard can be easily filled into the space below the gravity pressing frame 342.

[0065] The working principle and usage process of this utility model: When using this device, the roller distance between the two sets of creasing rollers 21, the two sets of first conveying rollers 22, and the two sets of second conveying rollers 23, as well as the groove height of the feeding groove 312, are adjusted according to the required thickness of the creasing support plate. During adjustment, the first screw 210 is rotated by the knob 41 at one end of the first screw 210. This drives the roller distance adjusting slider 29 to slide along the roller distance adjusting groove 28 through the transmission between the first screw 210 and the creasing conveying channel 1. The roller distance is adjusted by the engraving on the side of the creasing conveying channel 1. The scale line 42 controls the adjustment of the roller gap adjustment slider 29 to confirm the adjusted roller gap. The second screw 323 is rotated by the knob 41 at one end of the second screw 323. The transmission between the second screw 323 and the adjustment groove 321 drives the groove height adjustment plate 322 to slide along the adjustment groove 321. The groove height adjustment plate 322 is adjusted by the scale line 42 on the side of the adjustment groove 321 to confirm the adjusted groove height of the feeding groove 312. Through the above adjustment work, this device can be applied to the creasing work of paperboard of different thicknesses.

[0066] After completing the aforementioned adjustments, use the handle 343 to push the gravity pressing frame 342 up a certain height along the slide rail 341, and lock the gravity pressing frame 342 by tightening the locking bolt 5. Then, stack the cardboard with the indentation inside the feed hopper 311, and loosen the locking bolt 5 to lower the gravity pressing frame 342. Gravity generates a constant downward pressure on the stacked cardboard. Then, the device can be started. Turn on the first motor 26 and the second motor 335. The first motor 26 drives the first pulley 24 connected to its output end to rotate. Through the transmission between the first pulley 24 and the first belt 25, the indentation roller 21, the first conveyor roller 22, and the second conveyor roller 23 connected to the indentation conveying channel 1 are driven synchronously. The rotation of the rollers simultaneously drives the gears 27 located outside the creasing roller 21, the first conveyor roller 22, and the second conveyor roller 23 to rotate. Through the meshing transmission of the gears 27, the creasing roller 21, the first conveyor roller 22, and the second conveyor roller 23 located on the roller gap adjustment slider 29 rotate in opposite directions. At the same time, the second motor 335 drives the second pulley 333 connected to it to rotate. Through the transmission between the second pulley 333 and the second belt 334, the roller mounting rollers 331 rotate synchronously, thereby driving the rollers 332 to rotate. The rollers 332 outside the roller mounting rollers 331 rotate at the same speed. Under the downward pressure of the pressure frame 342 under gravity, the bottom layer of cardboard can form a tight contact with the rollers 332. This creates stable friction, preventing the cardboard from arching and hindering its smooth passage through the feeding trough 312. The rotating rollers 332 generate high-friction, low-damage multi-point active traction on the bottom layer of cardboard, feeding it into the feeding trough 312 in a stable posture. Under the restriction of the trough height adjustment plate 322, all cardboard except the bottom layer cannot move. The cardboard enters the creasing conveying channel 1 through the feeding trough 312, is pulled and conveyed towards the creasing rollers 21 by two creasing rollers 21 rotating in opposite directions, and after entering between the creasing rollers 21, the two rollers 21 complete the creasing process. Subsequently, driven by two second conveying rollers 23 rotating in opposite directions, it moves from the creasing conveying channel 1... The bottom output completes the creasing of a piece of cardboard. When a piece of cardboard is fed into the inner side of the creasing conveying channel 1 from inside the feeding hopper 311, the cardboard above it automatically falls and contacts the roller 332. Driven by the roller 332, it continues to be fed into the creasing conveying channel 1 for creasing. As the cardboard is continuously output, the gravity pressing frame 342 automatically slides down the slide rail 341 under the action of gravity, maintaining downward pressure on the cardboard and helping the bottom cardboard to maintain close contact with the roller 332, achieving stable automatic feeding. The operator only needs to refill the feeding hopper 311 after all the cardboard has been fed out. Compared with the manual feeding method of one piece of cardboard after another, it effectively reduces the workload of the operator.
