Description

Technical Field

[0001] This invention relates to the field of cardboard processing technology, and more specifically to a transverse creasing and embossing device for a carton printing and forming machine. Background Technology

[0002] A creasing machine is a machine used to cut various sheet materials, such as cardboard, corrugated cardboard, plastics and leather. It is widely used in the printing, packaging, decoration and plastics industries. It is divided into manual creasing machines and automatic creasing machines. For corrugated cardboard, a creasing device with a smaller output force can generally be selected to produce creasing.

[0003] In existing technology, after printing on cardboard, ordinary machines can only create vertical creases by pressing with crease rollers. For many cartons that require horizontal creases, the horizontal creases can only be achieved through secondary processing or by using a vertically moving creasing mechanism available on the market. Currently, the commonly available vertically moving creasing machines have poor precision, short lifespan, and slow speed. In actual production and processing, frequent equipment replacements require time and money, and the slow speed reduces production efficiency and cannot bring higher benefits. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: A transverse creasing and pressing device for a carton printing and forming machine includes a machine housing. A motor is fixedly connected to the inner wall of the machine housing. A creasing device is provided at the output end of the motor. A storage device is provided outside the creasing device. A pushing device is provided on the outer surface of the storage device. The creasing device includes a driving gear. A driven gear is meshed with the outer surface of the driving gear. An upper creasing roller is fixedly connected to the inner surface of the driven gear. A lower creasing roller is provided below the upper creasing roller. Synchronizing gears are provided on both sides of the lower creasing roller. A first driven gear is meshed with the outer surface of the synchronous gear. A second driven gear is meshed with the outer surface of the first driven gear. The outer surface of the second passive gear is meshed with a rotating gear. An adjustment component is located below the rotating gear, and a bellows gear is located above the adjustment component. The upper roller, driven by the main drive gear, drives the lower roller to rotate to the area where creasing is needed. Under the combined action of the gravure die fixed on the upper roller and the relief die fixed on the lower roller, the paperboard is plastically deformed by extrusion, achieving the purpose of transverse creasing. The entire machine uses gear transmission to ensure consistent linear speed and independent phase adjustment, thereby controlling the creasing position. By adjusting the size of the upper and lower rollers and the gear size, this mechanism can adapt to the creasing of different machine models. Due to the adoption of a rotary structure, the traditional vertical relative motion is transformed into reciprocating circular motion, greatly improving the creasing speed and accuracy.

[0005] Preferably, the storage device includes a support plate, a first rotating rod rotatably connected to the inner surface of the support plate, a support device provided on the outer surface of the first rotating rod, a second rotating rod provided above the support device, a movable rod provided above the second rotating rod, a fixed platform slidably connected to the outer surface of the movable rod, a sliding block slidably connected to the outer surface of the fixed platform, a connecting block fixedly connected to the outer surface of the sliding block, and a limit block rotatably connected to the outer surface of the connecting block. The feature is that the outer surface of the second rotating rod is slidably connected to the outer surface of the chassis, the outer surface of the chassis is fixedly connected to the outer surface of the fixed platform, and the outer surface of the limit block is slidably connected to the inner surface of the fixed platform. Due to its storage function and the upward sliding of the sliding block and the limit block on the fixed platform, all components on the support plate are stored close to the chassis, saving space. When not in use, the storage of the support plate prevents some external dust from entering the chassis.

[0006] Preferably, the pushing device includes an adjusting rod, a rotating shaft rotatably connected to the inner surface of the adjusting rod, a push plate fixedly connected to the outer surface of the rotating shaft, a lifting plate above the push plate, a transmission belt below the lifting plate, a connecting wheel rotatably connected to the inner surface of the transmission belt, a rotating plate fixedly connected to the upper surface of the connecting wheel, a rotating handle below the rotating plate, a fixed connection between the outer surface of the lifting plate and the outer surface of the rotating shaft, a rotatable connection between the outer surface of the rotating shaft and the inner surface of the transmission belt, a slidably connected support plate to the outer surface of the rotating plate, and a fixed connection between the lower surface of the rotating shaft and the upper surface of the rotating handle. When multiple cardboards are accumulated, they can be pushed into the creasing device separately, so that the cardboard is not creasing only on one side due to the multiple cardboards being placed in. The adjusting rod can adjust the distance between the rotating shafts, and the position of the connecting wheel can be adjusted by rotating the rotating plate, thereby accommodating cardboards of different sizes and pushing them into the creasing device.

[0007] The support device includes a connecting column, an extension rod rotatably connected to the inner surface of the connecting column, a pressing column inside the extension rod, a compression spring fixedly connected to the outer surface of the pressing column, a limit groove around the compression spring, a connecting strip outside the limit groove, a ratchet groove on the outer surface of the connecting strip, a pawl inside the ratchet groove, one end of the connecting strip fixedly connected to the outer surface of the pressing column, and the other end of the connecting strip fixedly connected to the outer surface of the pawl. The outer surface of the pressing column is slidably connected to the outer surface of the limit groove. A first rotating rod is rotatably connected to the connecting column. When storage is required, pressing the pressing column will compress the pressing spring. The limit groove ensures that the pressing column rotates slightly upon insertion. The connecting strip fixed to the pressing column will then pull the pawl, depriving it of its fixing effect. At this point, the extension rod can be rotated to retract.

[0008] Preferably, the outer surface of the compression spring is fixedly connected to the inner surface of the extension rod, the inner surface of the extension rod is fixedly connected to a ratchet groove, the output end of the motor is fixedly connected to the inner surface of the drive gear, and the outer surface of the drive gear is rotatably connected to the inner wall of the housing to prevent dust accumulation from partially affecting the wire pressing device.

[0009] The beneficial effects of this invention are as follows: 1. This invention, through the setting of a creasing device, when the cardboard is driven from front to back, the upper roller, driven by the main drive gear, simultaneously rotates the lower roller to the area requiring creasing. The gravure die fixed to the upper roller and the relief die fixed to the lower roller work together to cause plastic deformation of the cardboard through compression, achieving the purpose of transverse creasing. The entire machine uses gear transmission to ensure consistent linear speed and independent phase adjustment, achieving control of the creasing position. By adjusting the size of the upper and lower rollers and the gear size, this mechanism can adapt to the creasing of different machine models. The use of a rotary structure transforms the traditional vertical relative motion into reciprocating circular motion, greatly improving creasing speed and accuracy. Furthermore, the gear transmission structure further reduces manufacturing costs and can accommodate more... After printing on cardboard, ordinary machines can only create vertical creases by pressing with crease rollers. However, for many cartons that require horizontal creases, secondary processing or the use of commercially available up-and-down moving crease-pressing mechanisms are necessary to achieve the horizontal crease effect. Currently, the commonly available up-and-down reciprocating moving crease-pressing machines have poor precision, short lifespan, and slow speed. The new rotary structure transforms the up-and-down reciprocating motion into axial circular motion. This structure can precisely control the crease position, reduce metal fatigue, increase service life, and significantly improve processing speed while reducing labor costs. Mechanical transmission further reduces manufacturing costs. Without using a servo motor, gear transmission allows for easier connection with upstream and downstream units and ensures consistent linear speed.

[0010] 2. This invention uses a storage device to rotate the support plate by moving the first and second rotating rods. Simultaneously, due to its storage function and the sliding block and limiting block sliding upward on the fixed platform, all components on the support plate are stored near the chassis, saving space. When not in use, the storage of the support plate will prevent some external dust from entering the chassis, preventing dust accumulation from affecting the wire pressing device.

[0011] 3. This invention features a pushing device with an arc-shaped pusher plate on the rotating shaft to prevent damage to the carton and cardboard. A lifting plate, slightly higher than the pusher plate and with an inclined surface, allows the lifting plate to enter between the two layers of cardboard. During rotation, the lifting plate raises the upper cardboard to a higher position, allowing the pusher plate to more smoothly push the lower cardboard. When multiple cardboards accumulate, they can be pushed individually into the creasing device, preventing single-sided creasing during creasing. An adjusting rod adjusts the distance between the rotating shafts, and rotating the rotating plate adjusts the position of the connecting wheels, thus accommodating cardboard of different sizes and pushing it into the creasing device.

[0012] 4. By setting up a support device, when the storage device is fully unfolded, the internal rotating connection is changed to a ratchet structure. Therefore, when unfolded, it supports the rotating rod so that it cannot return to its original position due to gravity. When storage is needed, the pressing column is pressed, which will squeeze the pressing spring. By setting a limiting groove, the pressing column will rotate to a certain extent when it enters. The connecting strip fixed on the pressing column will pull the pawl, so that it no longer has a fixing effect. At this time, the extension rod can be rotated to retract. When released, the support effect is restored due to the elasticity of the compressed spring that pushes out part of the pressing column. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0015] Example 1: Please refer to Figure 1 - Figure 5This invention provides a technical solution: a transverse creasing and pressing device for a carton printing and forming machine, comprising a machine housing 1, a motor 3 fixedly connected to the inner wall of the machine housing 1, a creasing device 2 provided at the output end of the motor 3, a storage device 4 provided outside the creasing device 2, a pushing device 5 provided on the outer surface of the storage device 4, the creasing device 2 including a driving gear 21, a driven gear 22 meshing with the outer surface of the driving gear 21, an upper creasing roller 23 fixedly connected to the inner surface of the driven gear 22, a lower creasing roller 24 provided below the upper creasing roller 23, and synchronous gears 25 provided on both sides of the lower creasing roller 24, the outer surface of the synchronous gears 25 meshing with a first A first passive gear 26 is connected to a second passive gear 27 on its outer surface. The outer surface of the second passive gear 27 is connected to a rotating gear 28. An adjustment component 29 is located below the rotating gear 28, and a bellows gear 210 is located above the adjustment component 29. The lower roller gap is adjusted by fixing the adjustment gear and adjustment shaft to the wall plate through a keyless bushing, preventing them from moving back and forth and allowing only circular motion. This drives the eccentric sleeve to rotate to achieve the purpose of adjusting the pressure. The unique double eccentric structure allows the lower roller to move up and down in a straight line when adjusting the pressure, thereby ensuring the phase accuracy of the upper and lower rollers. The linear mold is connected to the upper and lower rollers by bolts.

[0016] Example 2: Please refer to Figure 6 - Figure 9The present invention provides a technical solution: Based on embodiment one, the storage device 4 includes a support plate 41, a first rotating rod 42 rotatably connected to the inner surface of the support plate 41, a support device 43 provided on the outer surface of the first rotating rod 42, a second rotating rod 44 provided above the support device 43, a movable rod 45 provided above the second rotating rod 44, a fixed platform 46 slidably connected to the outer surface of the movable rod 45, a sliding block 47 slidably connected to the outer surface of the fixed platform 46, a connecting block 48 fixedly connected to the outer surface of the sliding block 47, and a limiting block 49 rotatably connected to the outer surface of the connecting block 48. The feature is that the outer surface of the second rotating rod 44 is slidably connected to the outer surface of the housing 1, the outer surface of the housing 1 is fixedly connected to the outer surface of the fixed platform 46, and the outer surface of the limiting block 49 is slidably connected to the inner surface of the fixed platform 46. The support plate 41 is rotated by moving the first rotating rod 42 and the second rotating rod 44. Two first rotating rods 42 are provided. There are two second rotating rods 44. The two ends of the upper moving first rotating rod 42 are rotatably connected to two second rotating rods 44. The upper second rotating rod 44 is rotatably connected to the movable rod 45, and the lower second rotating rod 44 is slidably connected to the chassis 1. The lower first rotating rod 42 is rotatably connected to the sliding block 47. Since the sliding block 47 is fixedly connected to the connecting block 48, the connecting block 48 slides on the fixed platform 46. The movable rod 45 is fixedly connected to the limiting block 49, and the movable rod 45 is slidably connected to the fixed platform 46. When stored, the lower first rotating rod 42 rotates clockwise when viewed from the right view, the upper first rotating rod 42 rotates counterclockwise, the lower second rotating rod 44 rotates counterclockwise with the connection point of the chassis 1 as the center, and the upper second rotating rod 44 moves the movable rod 45 in a circular counterclockwise rotation. At the same time, due to its storage function and the upward sliding of the sliding block 47 and the limiting block 49 on the fixed platform 46, all components on the overall support plate 41 are stored in a position close to the chassis 1.

[0017] The pushing device 5 includes an adjusting rod 51, with a rotating shaft 52 rotatably connected to the inner surface of the adjusting rod 51. A push plate 53 is fixedly connected to the outer surface of the rotating shaft 52. A lifting plate 54 is disposed above the push plate 53, and a transmission belt 55 is disposed below the lifting plate 54. A connecting wheel 56 is rotatably connected to the inner surface of the transmission belt 55, and a rotating plate 57 is fixedly connected to the upper surface of the connecting wheel 56. A rotating handle 58 is disposed below the rotating plate 57. The outer surface of the lifting plate 54 is fixedly connected to the outer surface of the rotating shaft 52, and the outer surface of the rotating shaft 52 is rotatably connected to the inner surface of the transmission belt 55. A support plate 41 is slidably connected to the outer surface of the rotating plate 57, and the lower surface of the rotating shaft 52 is slidably connected to the inner surface of the rotating handle 58. The upper surface of 8 is fixedly connected. When the handle 58 rotates the shaft 52, the motion is transmitted to the connecting wheel 56 through the transmission belt 55. Since the upper end of the connecting wheel 56 is a cylinder and the lower end is a gear, the two connecting wheels 56 are connected by meshing and transmission, so that the two shafts 52 can rotate synchronously and in opposite directions through another transmission belt 55. There is a push plate 53 with an arc shape on the shaft 52 so that the carton and cardboard will not be damaged. A lifting plate 54 is set above it, which is slightly higher than the push plate 53 and has an inclined surface so that the lifting plate 54 can enter the middle of the two layers of cardboard. When rotating, the upper cardboard is lifted by the lifting plate 54, and the push plate 53 can push the lower cardboard more smoothly.

[0018] The support device 43 includes a connecting post 431, an extension rod 432 rotatably connected to the inner surface of the connecting post 431, a pressing post 433 disposed inside the extension rod 432, a compression spring 434 fixedly connected to the outer surface of the pressing post 433, a limit groove 435 disposed around the compression spring 434, a connecting strip 436 disposed outside the limit groove 435, a ratchet groove 437 disposed on the outer surface of the connecting strip 436, a ratchet pawl 438 disposed inside the ratchet groove 437, and one end of the connecting strip 436 being connected to the outer surface of the pressing post 433. The two extension rods 432 are fixedly connected to each other. The other end of the connecting bar 436 is fixedly connected to the outer surface of the pawl 438. The outer surface of the pressing post 433 is slidably connected to the outer surface of the limiting groove 435. The connecting post 431 is rotatably connected to the first rotating rod 42. The connecting post 431 rotatably connected to the first rotating rod 42 drives the extension rod 432 to rotate. Since the internal structure of the two extension rods 432 rotatably connected is changed to a ratchet structure by setting a ratchet groove 437 and a pawl 438, it will support the rotating rod when it is folded up so that it cannot return to its original position due to gravity.

[0019] The outer surface of the compression spring 434 is fixedly connected to the inner surface of the extension rod 432. The inner surface of the extension rod 432 is fixedly connected to a ratchet groove 437. The output end of the motor 3 is fixedly connected to the inner surface of the drive gear 21. The outer surface of the drive gear 21 is rotatably connected to the inner wall of the housing 1. When the extension rod 432 is rotated to retract, the support effect is restored by the spring force of the compression spring popping out a portion of the pressing column 433.

[0020] Working principle: In use, the creasing device 2 creates transverse indentations on the cardboard. The transmission process involves the motor 3 driving the drive gear 21, which in turn drives the driven gear 22. Simultaneously, the upper creasing roller 23 rotates. Since the rotating gear 28 and the upper creasing roller 23 are coaxial and fixedly connected, they drive the second driven gear 27 to rotate the first driven gear 26, thus causing the synchronous gear 25 to rotate. Because the synchronous gear 25 and the rotating gear 28 have the same number of teeth, and the two gears that drive the transmission have the same tooth module, the upper creasing roller 23 and the lower creasing roller 24 can achieve synchronized linear speeds. Simultaneously, through other gear transmissions, the bellows gear 210 moves, making the cardboard move more smoothly inside. The motion, specifically the pressing device 2, is equipped with a wall plate support section (one-stage pressing operation side wall plate, one-stage pressing non-operation side wall plate, two-stage pressing operation side wall plate, two-stage pressing non-operation side wall plate, channel steel support on the wall plate, and pipe support below the wall plate), a pressing upper roller section (pressing upper roller, upper bushing, bearing, pressing upper die, pressing upper roller non-operation side gear, keyless connecting sleeve, snap ring, oil seal), a main drive gear section (pressing roller gear, inner gear core, outer gear core, planetary carrier, spacer, keyless connecting sleeve, star wheel shaft, star wheel, snap ring), a main drive intermediate wheel (intermediate wheel seat, bearing, main drive intermediate wheel, snap ring), a pressing lower roller section (pressing lower roller, pressing lower die, snap ring, inner eccentric sleeve, outer eccentric sleeve, oil seal, bearing), and a secondary drive section (secondary drive gear, keyless connecting sleeve, etc.). The components include: connecting sleeve, fixed seat, slider connecting seat, rubber toothed umbilicus, pressure cover, copper plate, cross slider, bearing, connecting seat pressure cover, one-way clutch, adjusting assembly 29 (lower roller gap adjustment part, adjusting shaft, adjusting gear A, adjusting gear B, keyless connecting sleeve), and paper feeding air box (air box, air box base, air box gear 210, air box connecting sleeve, bearing, keyless connecting sleeve). Their interconnection method is as follows: upper and lower braces connect the wall panels together with bolts; the contact roller is connected to the wall panel via an upper shaft sleeve, which is then fixed to the wall panel with bolts; the main drive gear is fixed to the contact roller via bearings and a keyless connecting sleeve; the main drive intermediate wheel is fixed to the intermediate wheel seat via bearings and a retaining spring, and then the intermediate wheel seat is fixed to the contact wall panel with bolts; the auxiliary drive intermediate wheel... Similar to the connection method of the main drive intermediate wheel, the upper roller gear of the auxiliary drive part is connected and fixed to the upper roller through a keyless bushing, while the lower roller gear is fixed to the bearing seat through a bearing. The bearing is fixed by a cover, and the cross slider ensures that the center distance of the gears always remains in the appropriate position no matter how the lower roller is adjusted. The slider connecting seat is connected to the lower roller under the fixation of the one-way clutch and the connecting seat cover. The connecting seat cover is fixed to the slider connecting seat and the one-way clutch by bolts. The shaft end of the bellows extending out of the wall plate is fixed to the wall plate through the bellows connecting sleeve and bearing. The bellows gear 210 is fixed to the shaft end with a keyless connecting sleeve. The gear drives the negative pressure bellows to feed paper through the power transmitted by the synchronous pulley part of the bellows. The lower roller that touches the wall plate is fixed in the hole in the wall plate through the inner and outer eccentric sleeves and bearings.The lower roller gap adjustment is achieved by fixing the adjusting gear and adjusting shaft to the wall plate via a keyless bushing, preventing back-and-forth movement and allowing only circular motion. This drives the eccentric sleeve to rotate, thus adjusting the pressure. The unique double eccentric structure allows the lower roller to move linearly up and down during pressure adjustment, ensuring the phase accuracy of the upper and lower rollers. The linear mold is connected to the upper and lower rollers via bolts.

[0021] In use, the storage device 4 drives the support plate 41 to rotate via the movable first rotating rod 42 and the second rotating rod 44. Two first rotating rods 42 and two second rotating rods 44 are provided. The two ends of the upper movable first rotating rod 42 are rotatably connected to two second rotating rods 44. The upper second rotating rod 44 is rotatably connected to the movable rod 45, and the lower second rotating rod 44 is slidably connected to the housing 1. The lower first rotating rod 42 is rotatably connected to the sliding block 47. Since the sliding block 47 is fixedly connected to the connecting block 48, the connecting block 48 slides on the fixed platform 46. The movable rod 45 is fixedly connected to the limiting block 49, and the movable rod 45 is connected to the fixed platform 46. 6. Sliding connection. When stored, the lower first rotating rod 42 rotates clockwise when viewed from the right view, the upper first rotating rod 42 rotates counterclockwise, the lower second rotating rod 44 rotates counterclockwise around the connection point of the chassis 1, and the upper second rotating rod 44 moves the movable rod 45 in a circular counterclockwise direction. At the same time, due to its storage function and the sliding block 47 and the limiting block 49 sliding upward on the fixed platform 46, all components on the overall support plate 41 are stored in a position close to the chassis 1, saving space. When not in use, the support plate 41, being stored, will block some external dust from entering the interior of the chassis 1, preventing the accumulation of dust from affecting the wire pressing device 2.

[0022] In use, by setting up the pushing device 5, when the handle 58 is turned, the rotating shaft 52 is rotated, and the motion is transmitted to the connecting wheel 56 through the transmission belt 55. Since the upper end of the connecting wheel 56 is cylindrical and the lower end is a gear, the two connecting wheels 56 are connected by meshing, so that the two rotating shafts 52 can rotate synchronously and in opposite directions through another transmission belt 55. There is a push plate 53 on the rotating shaft 52 with an arc shape to prevent damage to the carton and cardboard. A lifting plate 54 is set above it, slightly higher than the push plate 53 and with an inclined surface, so that the lifting plate 54 can be raised. When the cardboard is inserted between two layers of cardboard, the upper cardboard is raised by the lifting plate 54 during rotation. The push plate 53 can then push the lower cardboard more smoothly. When multiple cardboards are stacked, they can be pushed into the creasing device 2 separately so that the cardboard is not creasing only on one side due to the multiple layers of cardboard. The adjusting rod 51 can adjust the distance between the rotating shafts 52. By rotating the rotating plate 57, the position of the connecting wheel 56 can be adjusted to accommodate cardboards of different sizes and push them into the creasing device 2.

[0023] In use, by setting the support device 43, when the storage device 4 is fully unfolded, the connecting column 431 connected to the first rotating rod 42 drives the extension rod 432 to rotate. Since the internal structure of the two extension rods 432 is changed to a ratchet structure by setting a ratchet groove 437 and a pawl 438, the rotating rod is supported when unfolded so that it cannot return to its original position due to gravity. When it needs to be stored, press the pressing column 433. The pressing column 433 will squeeze the pressing spring 434. By setting the limiting groove 435, the pressing column 433 will rotate a certain amount when it enters. The connecting strip 436 fixed on the pressing column 433 will pull the pawl 438, so that it no longer has a fixing effect. At this time, the extension rod 432 can be rotated to retract. When released, the support effect is restored by the elastic force of the compressed spring popping out part of the pressing column 433.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
