[0033] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0034] Example 1

[0035] The carton processing machine of the embodiment of the present application can be applied to continuous folding cardboard and ordinary cardboard, and continuous folding cardboard is used more often. Figure 1A As shown, the carton processing machine includes a paperboard magazine 1, a paper changer 2 and a carton making machine 3, and the paper changer 2 and the carton making machine 3 are arranged at intervals;

[0036] Among them, Figure 3A As shown, the paper changer 2 is used to clamp cardboard 41 of various widths in vertical layers, and is also used to drive the cardboard 41 to move up and down in the vertical direction, and after the selected cardboard moves to a preset height, it drives the selected cardboard into the box making machine 3; the box making machine 3 is used to process the cardboard to form cartons, and the processing includes cutting, horizontal grooving, horizontal pressing, vertical pressing and vertical slitting.

[0037] In existing carton processing machines, the cardboard used as raw material is only a relatively large width of cardboard. Thus, when processing smaller cartons, a larger portion needs to be cut off, resulting in a large waste of cardboard.

[0038] In the carton processing machine of the embodiment of the present application, a paper changer clamps cardboard of various widths in a layered manner in the vertical direction. The paper changer can drive all the cardboards up and down in the vertical direction, so that the selected cardboard is moved to a preset height. In this way, the cardboard with the highest utilization rate can be selected from the various cardboard widths according to the size of the carton, and the selected cardboard is selected, so that the portion of the selected cardboard that is cut off is smaller, thereby reducing cardboard waste. The paper changer then drives the selected cardboard into the carton making machine, which cuts, slots, crimps, and slits the cardboard into cartons.

[0039] The selected cardboard enters the carton making machine from the front end, and is fed from front to back in the carton making machine, and is processed into a carton by horizontal cutting, horizontal slotting and creasing, and vertical slitting and creasing. The carton is fed with paper to be discharged, and the carton 42 is formed. Figure 1B and Figure 1C As shown, the horizontal cutting line 425, the horizontal slot 421, the horizontal pressing line 422, the longitudinal pressing line 424, and the longitudinal cutting line 423. Figure 2A 、 Figure 2B 、 Figure 2C and Figure 2D As shown, the box making machine 3 includes a longitudinal slitting and creasing module 30 for performing longitudinal creasing and longitudinal slitting. The longitudinal slitting and creasing module 30 includes a longitudinal cutter 31 , which is a cutter that integrates longitudinal slitting and creasing.

[0040] The structure of the longitudinal cutter of the longitudinal slitting and crimping module is described below.

[0041] In implementation, such as Figure 2E 、 Figure 2F 、 Figure 2G and Figure 2H As shown, the longitudinal cutter 31 includes:

[0042] Longitudinal tool mounting seat 311-1;

[0043] The longitudinal creasing wheel 312-1 and the cutter mounting arm 313-11 are installed at the bottom of the longitudinal cutter mounting seat 311-1 at intervals in front and back; wherein the longitudinal creasing wheel 312-1 is used to creasing the cardboard to form a longitudinal creasing line 424;

[0044] A cutter transmission assembly 314 is connected to the lower portion of the cutter mounting arm 313 - 11 , and the cutter transmission assembly 314 is arranged to be tilted backward and downward from the lower portion of the cutter mounting arm 313 - 11 ;

[0045] A longitudinal slitting knife 315-11 is connected to the lower end of the slitting knife transmission assembly 314 and is used to longitudinally slit the cardboard to form a longitudinal slitting line 423;

[0046] The bottom surface of the cutter transmission assembly 314 is a lower guide bottom surface 314-1 that is tilted downward from front to back. The lower guide bottom surface 314-1 is used to guide the cardboard with the curled head after the pressing line to move along the lower guide bottom surface 314-1 to under the longitudinal slitting knife 315-11.

[0047] The lower guide bottom surface 314-1 is tilted downward from front to back, that is, the paper feeding side is higher and the paper outlet side is lower. When the cardboard comes over, it can prevent the cardboard from getting stuck due to bending or warping, and can also guide the warped cardboard to pass along the lower guide bottom surface 314-1. The longitudinal pressing wheel 312-1, the cutter mounting arm 313-11, and the longitudinal slitting knife 315-11 are connected in sequence from front to back under the longitudinal tool mounting seat. During the movement of the cardboard from front to back, the longitudinal pressing wheel 312-1 presses the cardboard. After the cardboard is pressed, Figure 2C The right end of the middle cardboard will warp, hitting the lower guide bottom surface 314-1. Because the lower guide bottom surface of the cutter drive assembly tilts downward from front to back, the warped cardboard is pressed downward from front to back, moving it under the longitudinal slitting blade 315-11 for longitudinal slitting. This greatly reduces paper jams between the longitudinal creasing wheel and the longitudinal slitting blade.

[0048] In implementation, such as Figure 2C As shown, the rotation direction of the longitudinal slitting knife 315 - 11 makes the conveying direction of the lower edge of the longitudinal slitting knife consistent with the conveying direction of the cardboard 41 to guide the cardboard 41 to move under the longitudinal slitting knife 315 - 11.

[0049] The longitudinal slitting knife can achieve longitudinal slitting of the cardboard whether it rotates clockwise or counterclockwise. However, when the cardboard just contacts the longitudinal slitting knife, if the conveying direction of the lower edge of the longitudinal slitting knife is consistent with the conveying direction of the cardboard from front to back, the longitudinal slitting knife can not only play the role of longitudinal slitting, but also guide the movement of the cardboard. Figure 2C As shown, the longitudinal slitting knife 315 - 11 rotates counterclockwise in this viewing angle, which can also prevent the cardboard 41 from getting stuck and ensure that the cardboard passes smoothly.

[0050] Specifically, such as Figure 2C As shown, when the longitudinal slitting knife 315-11 is in the longitudinal slitting working position, the downward inclination angle of the lower guide bottom surface from front to back ranges from greater than or equal to 5 degrees to less than or equal to 25 degrees.

[0051] The longitudinal slitting knife has an initial position and a longitudinal slitting working position. When the longitudinal slitting knife is in the initial position, the longitudinal slitting knife is in a raised state and does not longitudinally slit the cardboard. When the longitudinal slitting knife is in the longitudinal slitting working position, the longitudinal slitting knife is in a depressed state and can longitudinally slit the cardboard.

[0052] In implementation, such as Figure 2B and Figure 2C As shown, the carton making machine also includes a second paper feeding module 322, and the longitudinal slitting knife 315-11 and the sun gear 323-13 of the second paper feeding module 322 are arranged at intervals; wherein, the sun gear of the second paper feeding module is used to feed the cardboard after the longitudinal slitting and pressing line to discharge the paper.

[0053] Specifically, such as Figure 2B and Figure 2C As shown, the gap between the longitudinal slitting knife 315-11 and the sun gear 323-13 of the second paper feeding module 322 is less than or equal to 20 cm; or the gap between the longitudinal slitting knife 315-11 and the sun gear 323-13 of the second paper feeding module 322 is greater than or equal to 1 mm and less than or equal to 200 mm.

[0054] like Figure 2C As shown, the gap between the longitudinal slitting knife 315-11 and the sun wheel 323-13 of the second paper feeding module 322 is smaller than the gap 315-13 after the longitudinal slitting knife. When the cardboard 41 passes through the longitudinal slitting knife 315-11 and its head is slightly tilted, it is pressed by the sun wheel 323-13 of the second paper feeding module 322, so that it cannot continue to tilt upward, thereby reducing the probability of paper jam between the longitudinal slitting knife and the sun wheel of the second paper feeding module.

[0055] In implementation, such as Figure 2E and Figure 2G As shown, the longitudinal cutter also includes:

[0056] The longitudinal pressing wheel cylinder 312-2 is fixed to the bottom of the longitudinal tool mounting seat 311-1;

[0057] The wire pressing cylinder connecting plate 312-3 is fixed to the end of the piston rod of the longitudinal wire pressing wheel cylinder 312-2;

[0058] The crimping wheel mounting seat 312-41 is fixed to the bottom of the crimping cylinder connecting plate 312-3, and the longitudinal crimping wheel 312-1 is rotatably connected to the crimping wheel mounting seat 312-41.

[0059] The crimping cylinder connecting plate and the crimping wheel mounting base are fixedly integrated. The longitudinal crimping wheel 312-1 is rotatably connected to the crimping wheel mounting base 312-41. The crimping cylinder connecting plate is fixed to the end of the piston rod of the longitudinal crimping wheel cylinder 312-2. This allows the piston rod of the longitudinal crimping wheel cylinder 312-2 to extend downward and reposition relative to the longitudinal tool mounting base. When the longitudinal crimping wheel is required to perform longitudinal crimping on the cardboard, it extends downward to perform the longitudinal crimping. When longitudinal crimping is not required, the longitudinal crimping wheel repositions downward. In this way, the downward extension and repositioning of the longitudinal crimping wheel are achieved through a simple structure.

[0060] In implementation, such as Figure 2G As shown, the cutter transmission assembly includes a cutter mounting shaft 314-33, and a longitudinal cutter transmission gear 314-21, a longitudinal cutter transition gear 314-22, and a longitudinal cutter driven gear 314-23 that are meshed in sequence; the longitudinal cutter transmission gear 314-21 is connected to the lower part of the cutter mounting arm 313-11, and the cutter mounting shaft 314-33 and the longitudinal cutter driven gear 314-23 are fixed;

[0061] The longitudinal slitting knife 315 - 11 is detachably connected to the slitting knife mounting shaft 314 - 33 .

[0062] The longitudinal slitter drive gear 314-21, the longitudinal slitter transition gear 314-22, and the longitudinal slitter driven gear 314-23 form a three-gear meshing transmission structure. The longitudinal slitter drive gear serves as the power input gear, while the longitudinal slitter driven gear serves as the power output gear. Driven by the driven gear and the slitter mounting shaft, the longitudinal slitter rotates. The longitudinal slitter drive gear, in turn, drives the slitter mounting shaft and the longitudinal slitter 315-11. This three-gear meshing transmission structure is compact and offers excellent synchronization, enabling the longitudinal slitter to rotate autonomously. This autonomously rotating longitudinal slitter boasts a high rotational speed, with the linear velocity of the slitter blade far exceeding the speed of the cardboard's advance. Below the longitudinal slitter is a cooperating slitter comb, between which the cardboard passes. This comb, like a comb, features evenly spaced teeth with arc-shaped upper edges made of a resilient material. When the cardboard needs to be cut longitudinally, the longitudinal slitting knife falls, and the blade of the longitudinal slitting knife falls into the gap between the teeth of the longitudinal slitting knife comb, completely cutting through the cardboard. The teeth of the longitudinal slitting knife comb provide good support for the cardboard, so that the cardboard will not be deformed when subjected to cutting force.

[0063] In implementation, such as Figure 2E and Figure 2GAs shown, the cutter transmission assembly further includes a cutter gear box 314-41 and a cutter gear box cover 314-42, wherein the cutter gear box and the cutter gear box cover form a cutter gear mounting box;

[0064] The longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 are arranged in the gear mounting box from the lower part of the cutter mounting arm 313-11 and tilted downward from front to rear;

[0065] The bottom surface of the cutter gear box cover is a lower guide bottom surface 314 - 1 that is inclined downward from front to rear.

[0066] In this way, the longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 are arranged in the gear mounting box.

[0067] The three gears are arranged in a gear mounting box, so that the debris that may be generated when the cardboard is processed is isolated outside the gear mounting box, reducing the impact on the gears; at the same time, the gears can also be effectively lubricated.

[0068] In implementation, the housing has three through holes and a cutter gear box ball bearing is fixed in each through hole, and the cutter gear box cover has a through hole and a cutter gear box cover ball bearing is fixed in each through hole;

[0069] like Figure 2G As shown, the cutter transmission assembly also includes:

[0070] The transmission gear positioning shaft 314-31 is fixed to the shaft hole of the longitudinal cutter transmission gear 314-21;

[0071] The transition gear mounting shaft 314-32 is fixed to the shaft hole of the longitudinal cutter transition gear 314-22;

[0072] The transmission gear positioning shaft 314-31, the transition gear mounting shaft 314-32 and the cutter mounting shaft 314-33 are respectively fixed to the inner rings of the cutter gear box ball bearing and the cutter gear box cover ball bearing.

[0073] The transmission gear positioning shaft 314-31 and the longitudinal cutter transmission gear 314-21 are fixed together. The transmission gear positioning shaft 314-31 is connected to the cutter gear box housing's ball bearings and the cutter gear box cover's ball bearings, allowing the transmission gear positioning shaft 314-31 and the longitudinal cutter transmission gear 314-21 to rotate within the gear mounting box. Similarly, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 can also rotate within the gear mounting box.

[0074] The cutter gear mounting box and the cutter mounting arm 313-11 formed by the cutter gear box 314-41 and the cutter gear box cover 314-42 are installed through bearings and the transmission gear positioning shaft 314-31, that is, the cutter transmission assembly as a whole can rotate around the transmission gear positioning shaft 314-31.

[0075] In implementation, such as Figure 2A 、 Figure 2D 、 Figure 2E and Figure 2G As shown, the longitudinal slitting and crimping module also includes:

[0076] The longitudinal tool transmission shaft 316-11 is fixedly connected to the through-hole shaft hole reserved in the center of the transmission gear positioning shaft 314-31;

[0077] The longitudinal tool driven gear 316 - 12 and the longitudinal tool driving gear 316 - 13 are externally meshed, so that the longitudinal tool driven gear and the longitudinal tool driving gear 316 - 13 rotate in opposite directions;

[0078] The longitudinal cutter driven gear 316-12 is fixed to the end of the longitudinal cutter transmission shaft 316-11, and the longitudinal cutter driving gear 316-13 is connected to the second paper feeding driving gear through a second driving synchronous belt mechanism;

[0079] The box making machine has a second paper feeding motor located below the cardboard position, and the output shaft of the second paper feeding motor is cooperatively connected with the second driving synchronous belt mechanism.

[0080] The longitudinal cutter driven gear 316-12, the longitudinal cutter drive shaft 316-11, and the longitudinal cutter drive gear 314-21 rotate in the same direction; the longitudinal cutter drive gear 314-21 and the longitudinal cutter driven gear 314-23 rotate in the same direction. The longitudinal cutter driven gear 314-23 and the longitudinal cutter driving gear 316-13 rotate in opposite directions, meaning that the longitudinal cutter driven gear 314-23 and the output shaft of the second paper feed motor rotate in opposite directions. The longitudinal cutter driven gear 314-23 rotates above the paperboard, while the second paper feed motor rotates below the paperboard to feed the paper. This ensures that the longitudinal cutter driven gear 314-23 and the second paper feed motor rotate in opposite directions, but the conveying direction of the lower edge of the longitudinal slitter is consistent with the conveying direction of the paperboard by the second paper feed motor.

[0081] Specifically, the longitudinal cutter drive shaft 316-11 is designed as a hexagonal shaft, and the central through-hole reserved for the transmission gear positioning shaft 314-31 is a hexagonal hole. This allows the longitudinal cutter drive shaft 316-11 to be fixedly connected to the central through-hole reserved for the transmission gear positioning shaft 314-31. Therefore, power is transmitted from the second paper feed motor to the longitudinal cutter drive shaft 316-11, and then to the longitudinal slitting blade 315-11, providing power to the longitudinal slitting blade 315-11.

[0082] In implementation, such as Figure 2F 、 Figure 2G and Figure 2H As shown, the cutter mounting shaft 314-33 of the cutter transmission assembly passes through the housing composed of the cutter gear box and the cutter gear box cover, and symmetrically extends out of both sides of the housing composed of the cutter gear box and the cutter gear box cover;

[0083] The longitudinal slitting knife 315 - 11 can be detachably mounted on both ends of the slitting knife mounting shaft 314 - 33 .

[0084] In this way, the longitudinal slitting knife 315-11 can be installed alone at either end of the slitting knife mounting shaft 314-33, or two longitudinal slitting knives 315-11 can be installed at both ends of the slitting knife mounting shaft 314-33, so that the installation of the longitudinal slitting knife 315-11 is possible in many ways and can be applied to more scenarios.

[0085] In implementation, such as Figure 2F 、 Figure 2G and Figure 2H As shown, the cutter transmission assembly is a symmetrical structure with the center line of the cutter mounting shaft 314-33 as the symmetry axis; the longitudinal cutter also includes a creasing wheel mounting shaft 312-42, which passes through the creasing wheel mounting seat and extends symmetrically, and the longitudinal creasing wheel 312-1 can be detachably mounted on either end and / or both ends of the creasing wheel mounting shaft 312-42;

[0086] There are at least two longitudinal cutters, each of which is coaxially mounted on the longitudinal cutter transmission shaft. The longitudinal slitting knives of two adjacent longitudinal cutters can be mounted on opposite sides so that the two longitudinal slitting knives are arranged adjacent to each other. The longitudinal pressing wheels of two adjacent longitudinal cutters can be mounted on opposite sides so that the two longitudinal pressing wheels are arranged adjacent to each other.

[0087] The longitudinal cutter structure is symmetrical, and longitudinal creasing wheels and longitudinal slitting knives can be installed on both sides, selectively installed according to processing requirements. This design enables the machine to process ultra-thin cartons. That is, when the longitudinal creasing wheels and longitudinal slitting knives are installed in opposite directions, the longitudinal creasing wheels of two adjacent longitudinal cutters can be close together, and the longitudinal slitting knives of two adjacent longitudinal cutters can be close together.

[0088] When there are multiple longitudinal cutters, the longitudinal slitting knives of each longitudinal cutter can be installed on the same side of the cutter transmission assembly. In this case, the minimum distance between the longitudinal slitting knives is the thickness of the cutter transmission assembly. Alternatively, the longitudinal slitting knives of two adjacent longitudinal cutters can be installed on opposite sides so that the two longitudinal slitting knives are arranged adjacent to each other. In this case, the distance between the two longitudinal slitting knives exceeds the thickness of the cutter transmission assembly. Therefore, the longitudinal slitting knives 315-11 can be detachably mounted on both ends of the cutter mounting shaft 314-33, which increases the possibility of varying the spacing between the longitudinal cuts of the carton processing machine and makes the carton processing machine more versatile.

[0089] like Figure 1B and Figure 1C As shown, there are transverse cutting lines 425, transverse slots 421, transverse pressing lines 422, longitudinal pressing lines 424, and longitudinal slitting lines 423. The thickness of the carton is determined by the distance between the two longitudinal slitting lines 423, which is determined by the distance between the longitudinal slitting blades 315-11 of two adjacent longitudinal cutters. The adjacent arrangement of the longitudinal slitting blades 315-11 of two adjacent longitudinal cutters allows for processing not only thicker cartons but also very thin cartons. The minimum carton thickness is the distance between the longitudinal slitting blades of two adjacent, closely spaced longitudinal cutters.

[0090] In implementation, such as Figure 2F As shown, the longitudinal cutter also includes:

[0091] The wire pressing wheel ball bearing, the longitudinal wire pressing wheel 312-1 is reserved with a through hole and the wire pressing wheel ball bearing is fixed in the through hole, the wire pressing wheel mounting shaft 312-42 is detachably fixed to the inner ring of the wire pressing wheel ball bearing, so that the longitudinal wire pressing wheel 312-1 can rotate around the wire pressing wheel mounting shaft 312-42.

[0092] During implementation, the longitudinal creasing wheel and the longitudinal slitting knife installed on the same side of the longitudinal knife are located in the same straight line.

[0093] In this way, the cardboard is firstly longitudinally pressed by the longitudinal pressing wheel, and then longitudinally cut at the longitudinal pressing position.

[0094] In implementation, such as Figure 2E 、 Figure 2F and Figure 2G As shown, the longitudinal cutter also includes:

[0095] The longitudinal slitting knife cylinder 315-12, the slitting knife mounting arm 313-11 and the longitudinal slitting knife cylinder 315-12 are fixed to the bottom of the longitudinal tool mounting base 311-1 with a front-to-back spacing. The piston rod of the longitudinal slitting knife cylinder 315-12 is fixed to the slitting knife transmission assembly 314 to drive the longitudinal slitting knife 315-11 to move downward and reset upward;

[0096] Among them, the longitudinal tool mounting seat 311-1 is located between the cutter mounting arm 313-11 and the longitudinal slitting knife cylinder 315-12 and has a longitudinal tool mounting seat wire hole 311-21 running through it from top to bottom, and the air inlet pipe and the air outlet pipe of the longitudinal slitting knife cylinder 315-12 pass through the longitudinal tool mounting seat wire hole 311-21.

[0097] Since the cutter transmission assembly as a whole can rotate around the transmission gear positioning shaft 314-31, the longitudinal slitting knife cylinder 315-12 controls the rotation of the cutter transmission assembly, thereby controlling the rise and fall of the longitudinal slitting knife to complete the longitudinal cutting action of the cardboard.

[0098] The longitudinal cutter mounting base 311-1 has a longitudinal cutter mounting base wire hole 311-21, allowing the air inlet and outlet pipes of the longitudinal slitting blade cylinder 315-12 to be conveniently connected to an external air source through the longitudinal cutter mounting base wire hole 311-21. This fully utilizes the space in the longitudinal cutter mounting base 311-1, making the overall routing of the longitudinal cutter's air inlet and outlet pipes relatively simple.

[0099] In implementation, such as Figure 2E 、 Figure 2F and Figure 2G As shown, the longitudinal creasing wheel cylinder 312-2 is fixed to the bottom of the longitudinal tool mounting seat 311-1 and is located in front of the cutter mounting arm 313-11;

[0100] Among them, the cutter mounting arm 313-11 has a cutter mounting arm wire hole 313-12 that passes through the front and back, and the air inlet pipe and the air outlet pipe of the longitudinal wire pressing wheel cylinder 312-2 pass through the cutter mounting arm wire hole 313-12 and the longitudinal tool mounting seat wire hole 311-21 in turn.

[0101] The air inlet pipe and the air outlet pipe of the longitudinal crimping wheel cylinder 312-2 pass through the cutter mounting arm wire hole 313-12 and the longitudinal tool mounting seat wire hole 311-21 in turn and are connected to the external air source. The air inlet pipe and the air outlet pipe of the longitudinal crimping wheel cylinder 312-2 share the longitudinal tool mounting seat wire hole 311-21 with the air inlet pipe and the air outlet pipe of the longitudinal slitting knife cylinder 315-12, making the overall routing of the air inlet pipe and the air outlet pipe relatively simple.

[0102] The longitudinal creasing wheel is controlled up and down by the longitudinal creasing wheel cylinder 312-2. When the cardboard needs to be longitudinally creasing, the longitudinal creasing wheel cylinder controls the longitudinal creasing wheel to drop and press the cardboard. The longitudinal creasing wheel cooperates with the longitudinal creasing roller directly below to complete the longitudinal creasing on the cardboard.

[0103] In implementation, such as Figure 2E 、 Figure 2F and Figure 2G As shown, the longitudinal cutter also includes:

[0104] A longitudinal tool motor mounting member is fixed to the top of the longitudinal tool mounting seat 311-1. The longitudinal tool motor mounting member has a longitudinal tool motor mounting member wire passing space that passes through the longitudinal tool motor mounting member, and the longitudinal tool motor mounting member wire passing space and the longitudinal tool mounting seat wire passing hole 313-12 are arranged vertically;

[0105] Among them, the air inlet pipe and the air outlet pipe of the longitudinal wire pressing wheel cylinder and the air inlet pipe and the air outlet pipe of the longitudinal slitting knife cylinder passing through the wire hole of the longitudinal tool mounting seat pass through the wire space of the longitudinal tool motor mounting piece from bottom to top.

[0106] In this way, the longitudinal cutter motor mounting member realizes the installation of the longitudinal cutter motor on the one hand, and realizes the passage of the air inlet pipe and the air outlet pipe on the other hand.

[0107] In implementation, such as Figure 2E 、 Figure 2F and Figure 2G As shown, the longitudinal tool motor mount consists of:

[0108] Two flange support plates 317 - 11 , the two flange support plates 317 - 11 are fixed in parallel on the top of the longitudinal tool mounting seat 311 - 1 ;

[0109] The motor flange seat 317-12 has a motor flange seat shaft hole and a motor flange seat wire hole 317-13 arranged in front and back. The space between the two flange support plates 317-11 and the motor flange seat wire hole 317-13 are connected to form a longitudinal tool motor mounting part wire passing space;

[0110] The longitudinal tool further includes a longitudinal tool motor 317 - 2 , which is fixed on the motor flange seat 317 - 12 , and the output shaft of the longitudinal tool motor 317 - 2 extends downward from the shaft hole of the motor flange seat.

[0111] The longitudinal cutter motor mounting component composed of two flange support plates 317 - 11 and a motor flange seat 317 - 12 has a simple structure and not only realizes the installation of the longitudinal cutter motor but also realizes the passage of the air inlet pipe and the air outlet pipe.

[0112] Several cable holes are designed inside the longitudinal cutter: cable holes 311-21 in the longitudinal cutter mounting base, cable holes 313-12 in the cutter mounting arm, and cable holes 317-13 in the motor flange. These holes are used to pass the longitudinal cutter's air pipes and motor cables. This helps maintain the longitudinal cutter's volume and keeps the spacing between adjacent longitudinal cutters unaffected by air pipe routing. This design also keeps wiring neat and facilitates securing air pipes and motor cables.

[0113] The other structures of the longitudinal slitting and crimping module are described below.

[0114] In implementation, such as Figure 2D and Figure 2E As shown, the longitudinal slitting and crimping module also includes:

[0115] a longitudinal tool mounting beam 318 - 11 , wherein the longitudinal tool mounting beam 318 - 11 is fixed to the inner side of the box making machine frame 32 ;

[0116] A meshing longitudinal tool rack 318-12 and a longitudinal tool gear 318-13, wherein the longitudinal tool gear 318-13 is fixed to the outer peripheral surface of the output shaft of the longitudinal tool motor, and the longitudinal tool rack 318-12 is fixed to the side surface of the longitudinal tool mounting beam 318-11 along the length direction of the longitudinal tool mounting beam;

[0117] The longitudinal tool motor 317 - 2 drives the longitudinal tool gear 318 - 13 to rotate, and the rotation of the longitudinal tool gear 318 - 13 drives the longitudinal tool to move along the length direction of the longitudinal tool mounting beam 318 - 11 ;

[0118] Wherein, the longitudinal tool gear is a helical gear.

[0119] The longitudinal cutter motor, longitudinal cutter gear, longitudinal cutter rack, and longitudinal cutter mounting beam work together to enable the longitudinal cutter motor to drive the longitudinal cutter to move along the length of the longitudinal cutter mounting beam. This allows the longitudinal cutter to move along the length of the longitudinal cutter mounting beam, allowing the longitudinal cutter's creasing wheel to move up and down to creasing the cardboard longitudinally, and the longitudinal cutter's longitudinal slitting blade to move up and down to longitudinally slit a portion of the cardboard at the creasing position.

[0120] In implementation, such as Figure 2E and Figure 2G As shown, the longitudinal slitting and crimping module also includes:

[0121] The longitudinal tool slider 318-21 and the longitudinal tool slide rail are slidably matched, and the longitudinal tool slider 318-21 is fixed on the top of the longitudinal tool mounting seat 311-1 and is located above the longitudinal line pressing wheel cylinder 312-2; the longitudinal tool slide rail is fixed to the bottom of the longitudinal tool mounting beam 318-11 along the length direction of the longitudinal tool mounting beam 318-11, that is, the longitudinal tool is slidably connected to the longitudinal tool mounting beam 318-11 through the longitudinal tool slide rail and the longitudinal tool slider 318-21.

[0122] As the longitudinal tool motor drives the longitudinal tool along the length of the longitudinal tool mounting beam, the longitudinal tool slider and longitudinal tool rail slide in unison to guide the direction of movement. The longitudinal tool rack and longitudinal tool gear, in conjunction with the longitudinal tool slider and longitudinal tool rail, ensure balanced force and smooth movement along the length of the longitudinal tool mounting beam.

[0123] Specifically, a longitudinal tool slider positioning plate is fixed between the two longitudinal tool sliders to position the longitudinal tool sliders and keep the relative distance between the two longitudinal tool sliders consistent, so that each longitudinal tool can move smoothly on the longitudinal tool slide rail.

[0124] The other structures of the box making machine are described below.

[0125] In implementation, such as Figure 2A 、 Figure 2B and Figure 2C As shown, the box making machine also includes:

[0126] The box making machine frame 32, the front and rear parts of the box making machine frame 32 are the paper feeding side and the paper discharging side respectively;

[0127] A first paper feeding module 321 provided on the paper feeding side;

[0128] A second paper feeding module 322 and a second transverse cutting module 332 are arranged on the paper discharge side in front and back, and the second transverse cutting module 332 can move up and down and can move in the transverse direction to perform transverse cutting; the transverse direction is perpendicular to the front-to-back direction and the vertical direction;

[0129] The carton processing machine further includes a control unit, which processes the cardboard between the first paper feeding module and the second paper feeding module:

[0130] When the preset length of the processed carton is less than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, and when the actual length of the processed carton after passing through the second transverse cutting module 332 has reached the preset length of the processed carton, the first paper feeding module 321 and the second paper feeding module 322 are controlled to stop feeding paper, and the second transverse cutting module 332 is controlled to move downward and the cardboard is transversely cut in the transverse direction to form a transverse cutting line 425.

[0131] When the preset length of the processed carton is less than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the front end of the cardboard is first conveyed by the first paper feeding module 321. When the actual length of the cardboard after passing through the second transverse cutting module 332 reaches the preset length of the processed carton and reaches the second paper feeding module 322, the first and second paper feeding modules 321 and 322 stop feeding the cardboard, and the second transverse cutting module 332 is controlled to move downward and cut the cardboard in the transverse direction. At this time, the length of the cut cardboard is the preset length of the processed carton. In other words, when the preset length of the processed carton is less than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the second transverse cutting module 332 is controlled to perform transverse cutting at an appropriate time. After being transversely cut, the cut cardboard is continued to be conveyed by the second paper feeding module 332 for paper discharge, and the first paper feeding module 331 no longer contacts it.

[0132] In implementation, such as Figure 2A 、 Figure 2B and Figure 2C As shown, the box making machine also includes:

[0133] A first transverse cutting module 331, wherein the first paper feeding module 321 and the first transverse cutting module 331 are arranged front and back on the paper feeding side, and the first transverse cutting module 331 can move up and down and can move in the transverse direction to perform transverse cutting;

[0134] The control unit is also used to: when the preset length of the processed carton is greater than the distance between the first paper feeding module 321 and the second paper feeding module 322, when the actual length of the processed carton after passing through the first transverse cutting module 331 has reached the preset length of the processed carton and the processed carton has reached the second paper feeding module 322, control the first paper feeding module 321 and the second paper feeding module 322 to stop feeding paper, and control the first transverse cutting module 321 to move downward and move in the transverse direction to cut the cardboard transversely.

[0135] When the pre-set length of the processed carton is greater than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the front end of the cardboard is first conveyed by the first paper feeding module 321. When the actual length of the cardboard after passing through the first transverse cutting module 321 reaches the pre-set length of the processed cardboard and the cardboard reaches the second paper feeding module 322, the first and second paper feeding modules 321 and 322 stop feeding the cardboard, and the first transverse cutting module 321 is controlled to move downward and cut the cardboard in the transverse direction. At this time, the length of the cut cardboard is the pre-set length of the processed cardboard. In other words, when the pre-set length of the processed carton is greater than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the first transverse cutting module 321 is controlled to perform transverse cutting at an appropriate time. After transverse cutting, the cut cardboard is further conveyed by the second paper feeding module 332 for discharge, and the first paper feeding module 331 no longer contacts it.

[0136] In implementation, such as Figure 2B and Figure 2I As shown, the box making machine also includes:

[0137] A transverse slotting and creasing module 34 is disposed between the first transverse cutting module 331 and the second paper feeding module 322. The transverse slotting and creasing module 34 comprises two slotting blades 341 spaced apart in the transverse direction. The two slotting blades 341 are capable of moving up and down and can move toward and away from each other in the transverse direction. The two slotting blades 341 maintain a spacing when they are at their closest distance toward each other.

[0138] The control unit is further configured to control the two slotting knives 341 to move toward or away from each other first, and then move downward to perform slotting in the width direction of the cardboard, forming a transverse slot 421 , when the preset transverse slotting depth D is less than or equal to the length of the slotting knife 341 .

[0139] The two slotting knives can move toward and away from each other in the transverse direction, adapting to various cardboard widths. When the cardboard width is small, the two slotting knives can move toward each other, aligning their outer edges with the widthwise edge of the cardboard. When the cardboard width is small, the two slotting knives can move away from each other, aligning their outer edges with the widthwise edge of the cardboard. This allows cartons to be processed using cardboard of varying widths.

[0140] When the carton requires transverse slotting to a preset depth D greater than the length of the slotting blade 341, the control unit coordinates with the first transverse cutting module and the second transverse cutting module to complete the processing. The control unit is also configured to control the first transverse cutting module and the second transverse cutting module to perform cutting at the transverse slotting position, and the cutting length is the preset transverse slotting depth D, when the preset transverse slotting depth D is greater than the length of the slotting blade.

[0141] Specifically, such as Figure 2B and Figure 2J As shown, the slotting knife 341 has a larger outer end and a smaller inner end. The box making machine also includes two lower slotting knives located below the cardboard, with a gap between the two lower slotting knives. When the slotting knives are slotting, the slotting knife 341 moves downward, forming a shearing fit with the two lower slotting knives to slot the cardboard.

[0142] In this way, when the cardboard is slotted horizontally, it is a linear cutting action, and the slotting resistance is small.

[0143] Specifically, such as Figure 2J As shown, the slotting knife 341 has a certain thickness, and there are two slotting blades 341-1. There is a groove between the two slotting blades 341-1. When slotting, a long strip of paper scraps will be cut off from the cardboard, forming a gap with a certain width on the cardboard (illustrating the carton slots on the carton), which facilitates the molding of the carton.

[0144] Specifically, such as Figure 2J As shown, the outer end of the slotting knife has a slotting knife guide angle 341-2, which guides the slotting knife to fall smoothly into the gap between the two lower slotting knives; the inner end of the slotting knife has a slotting knife cutting edge 341-3, which cuts off the long strips of paper scraps on the cardboard and separates them from the cardboard.

[0145] When the slotting knife is slotting, the slotting knife moves downward, and the outer end of the slotting knife is slotted first.

[0146] Specific examples Figure 2B As shown, the transverse slotting and crimping module further comprises a long crimping knife 342, and the crimping knife 342 and the slotting knife are arranged vertically;

[0147] The crimping knife 342 and the slotting knife can move up and down as a whole, so that when the crimping knife moves downward to press the cardboard horizontally to form a horizontal crimping line 422, the slotting knife moves downward and moves toward each other to slot the cardboard.

[0148] The cardboard passes from the first paper feeding module and passes between the slotting blade 341 and the two lower slotting blades. The transverse slotting and creasing module completes the carton transverse slotting and creasing process. This allows the transverse slotting and creasing module to complete both transverse creasing and slotting in a single downward movement, resulting in high efficiency. In the prior art, transverse slotting and creasing are accomplished by each component pressing downward once.

[0149] The structure of the paper changer will be described below.

[0150] In implementation, such as Figure 3A As shown, the paper changer includes:

[0151] Paper changer frame 21;

[0152] A paper changer channel module is vertically slidably connected to the paper changer frame 21. The paper changer channel module has a plurality of paper changer channels 221 installed at intervals in layers. Each paper changer channel 221 is used to clamp paperboard of a certain width.

[0153] The paper changer channel advance and retreat mechanism is used to move the selected paper changer channel 221 forward after it moves to a preset height to carry out subsequent cardboard processing steps; it is also used to reset the selected paper changer channel 221 forward after the cardboard processing is completed.

[0154] Each paper changer channel clamps a cardboard of one width, so the paper changer channel module can clamp cardboards of multiple widths in a layered manner in the vertical direction. The paper changer channel module is vertically slidably connected to the paper changer frame, so that the paper changer channel module can move up and down in the vertical direction as a whole, thereby realizing the vertical movement of all cardboards, and then moving the selected cardboard to a preset height. The paper changer channel advance and retreat mechanism realizes that after the selected paper changer channel moves to the preset height, the selected paper changer channel moves backward, that is, drives the selected cardboard into the carton making machine for processing; it can also realize that after the cardboard processing is completed, the remaining selected cardboard is withdrawn from the carton making machine. The existence of the paper changer allows the selected cardboard to enter the carton making machine for processing, and the withdrawal of the remaining selected cardboard is achieved through the paper changer and the corresponding control, which is faster, more convenient, and highly automated.

[0155] In implementation, such as Figure 3A and Figure 3B As shown, the paper changer channel 221 of each layer is centrally arranged in the transverse direction;

[0156] The transverse direction is the width direction of the paperboard clamped by the paper changer channel 221 .

[0157] The paper changer channel is arranged in the center in the horizontal direction to facilitate the subsequent processing of the cardboard by the box making machine.

[0158] In implementation, such as Figure 3B As shown, each of the paper changer channels 221 includes:

[0159] A channel clamp mounting beam 221 - 1 , with raised channel limiting shafts 221 - 11 provided at both ends of the channel clamp mounting beam 221 - 1 ;

[0160] Two cardboard channel clips 221 - 2 are fixed symmetrically to the cardboard channel clip mounting beam 221 - 1 ;

[0161] The pressing cylinder 221 - 3 corresponds to the cardboard channel clamp 221 - 2 one by one and is fixed on the corresponding cardboard channel clamp 221 - 3 to press the cardboard on the cardboard channel clamp 221 - 2.

[0162] In implementation, such as Figure 3A and Figure 3B As shown, the paper changer channel module includes:

[0163] The paper changer channel 221;

[0164] Two paper changer channel module side panels 222, each of which has a plurality of paper changer channel slideways 223 arranged in intervals and layers and passing through the paper changer channel module side panels, and a channel limiting shaft 221-11 passes through the paper changer channel slideways 223 and protrudes from the paper changer channel module side panels 222;

[0165] The channel limiting shaft 221 - 11 can move forward and backward along the paper changer channel slide 223 .

[0166] The channel limiting shaft moves forward and backward along the paper changer channel slide 223, so that the paper changer channel can move forward and backward. The paper changer channel slide 223 plays a role of guiding and limiting.

[0167] Specifically, the length direction of the paper changer channel slide 223 is the front-to-back direction.

[0168] The channel limiting shaft and the paper changer channel slide cooperate to enable the paper changer channels on each layer to move forward and backward, with a simple structure.

[0169] In implementation, such as Figure 3C As shown, the paper changer further includes a paper changer channel advance and retreat mechanism, and the paper changer channel advance and retreat mechanism includes:

[0170] Two sections of paper changer channel limit slots 231, the guide direction of the paper changer channel limit slots 231 is vertical; wherein the paper changer channel limit slots 231 are fixed on the inner side of the paper changer frame; that is, the function of the paper changer frame includes installing the paper changer channel advance and retreat mechanism;

[0171] The paper changer advance and retreat cylinder 234 is fixed to the paper changer frame;

[0172] A movable limiting groove 232 is fixed on the cylinder body of the paper changer advance and retreat cylinder. The guiding direction of the movable limiting groove 232 is vertical. The movable limiting groove 232 is arranged between the two sections of the paper changer channel limiting grooves 231 so that the two sections of the paper changer channel limiting grooves 231 and the paper changer channel limiting groove 232 are connected to form an up and down motion channel. The channel limiting shaft 221-11 can move along the up and down motion channel.

[0173] The paper changer advance and retreat cylinder is a rodless cylinder, and the cylinder body of the paper changer advance and retreat cylinder can reciprocate in the front and rear directions on the cylinder shaft.

[0174] When the channel limiting shaft 221-11 is located in the paper changer channel limiting groove 231, the position of the paper changer channel is locked and cannot move forward or backward, that is, the front and rear positions of the paper changer channel are maintained.

[0175] When the channel limiting shaft 221-11 of any layer of the paper changer channel is located in the movable limiting groove 232, the paper changer channel of that layer has the ability to move forward and backward. As long as the movable limiting groove 232 starts to move forward and backward, the paper changer channel of that layer can be driven to move forward and backward.

[0176] When a certain paper changer channel needs to be sent into the carton making machine of the carton processing machine, the paper changer channel lifting mechanism moves the channel limit shaft of the selected paper changer channel into the movable limit slot, and the cylinder body of the paper changer advance and retreat cylinder moves backward, driving the movable limit slot and the selected paper changer channel to move backward, and sending the cardboard of the selected paper changer channel into the carton machine.

[0177] In implementation, such as Figure 3A and Figure 3C As shown, the paper changer further includes a paper changer channel lifting mechanism, and the paper changer channel lifting mechanism includes:

[0178] The paper changer channel lift rails 241 and slide blocks 242 slide vertically together. The rails 241 are located inside the paper changer frame 21, while the slide blocks 242 are fixed to the outside of the paper changer channel module side panels 222. In other words, another function of the paper changer frame is to mount the paper changer channel lift mechanism.

[0179] The paper changer channel lifting rail and the paper changer channel lifting slider cooperate with each other, so that the paper changer channel module as a whole has the ability to rise and fall. Specifically, the lifting of the paper changer channel module is achieved by the paper changer channel module lifting motor.

[0180] In this way, the paper changer frame is used to fix the paper changer channel lifting mechanism and the paper changer channel advancing and retreating mechanism.

[0181] In implementation, such as Figure 3A and Figure 3C As shown, the paper changer channel lifting mechanism also includes:

[0182] Channel entry detection sensor 251 and channel exit detection sensor 252;

[0183] A rodless cylinder mounting base, wherein the channel entry detection sensor 251 is provided at the front end of the rodless cylinder mounting base, and the channel exit detection sensor 252 is provided at the rear end to detect the slide of the paper changer in and out of the cylinder;

[0184] The control unit is further configured to determine whether the paper changer channel has reached a position by detecting whether the slide has reached a preset position:

[0185] The channel entry detection sensor 251 detects the slide of the paper changer advance and retreat cylinder, and determines that the paper changer channel has reached the preset position;

[0186] After the carton processing is completed, the paper changer channel retracts. After the channel exit detection sensor 252 detects the slide of the paper changer advance and retreat cylinder, it is determined that the paper changer channel has returned to its initial position and the paper changer channel can be raised and lowered.

[0187] In this way, when the paper changer channel reaches the preset position, the control unit determines that the paperboard has been correctly fed and can start the next step of the program. When the paper changer channel returns to the initial position, the control unit determines that the paper changer channel is reset and can be raised or lowered.

[0188] The channel entry detection sensor, channel exit detection sensor and control unit cooperate to realize the judgment of whether paper feeding is completed, and whether the paper changer channel is reset and can be raised or lowered after paper feeding is completed. The degree of automation is high, which reduces the workload of staff.

[0189] Specifically, such as Figure 3A As shown, casters 261 for movement are installed at the bottom of the paper changer.

[0190] The casters make it easy to move the paper changer during installation and maintenance.

[0191] Specifically, the paper changer channel lifting mechanism also includes a paper changer channel lifting motor 243-1, a paper changer transmission synchronous wheel 243-2, a paper changer transmission synchronous belt 243-3, a paper changer transmission shaft 243-4 and a paper changer lifting synchronous belt 243-5; the paper changer channel lifting motor 243-1 drives the paper changer transmission synchronous wheel 243-2 and the paper changer transmission synchronous belt 243-3 to rotate, and transmits the rotation to the paper changer lifting synchronous belt 243-5 through the paper changer transmission shaft 243-4, and the paper changer lifting synchronous belt 243-5 drives the paper changer channel lifting slider 242 to rise and fall, thereby realizing the lifting and lowering of the entire paper changer channel module.

[0192] In practice, the first paper feeding module 321 and the second paper feeding module 322 have the same structure. Figure 4A As shown, the first paper feeding module and the second paper feeding module each include:

[0193] Multiple sun gear modules 323-1;

[0194] The paper feed roller 323-2 is provided with a vertical interval between the sun gear module 323-1 and the paper feed roller 323-2. The interval between the sun gear module 323-1 and the paper feed roller 323-2 is used for paperboard to pass through. Each of the sun gear modules 323-1 can move up and down to leave and press the paperboard on the paper feed roller 323-2.

[0195] A paper feeding synchronous belt 323 - 3 and a paper feeding motor 323 - 4 , wherein the paper feeding synchronous belt 323 - 3 synchronously connects the output shaft of the paper feeding motor 324 - 4 and the paper feeding roller 323 - 2 ;

[0196] The control unit is further configured to select the number and position of the sun gear modules to be moved downward according to the width of the selected cardboard.

[0197] The carton processing machine can accommodate a variety of cardboard widths. When the selected cardboard is the largest width, all sun gear modules in the first paper feed module are selected, and all of them move downward to press against the cardboard. When the selected cardboard is smaller, some of the sun gear modules in the first paper feed module are selected, and only the selected sun gear modules move downward to press against the cardboard. This structure of the first and second paper feed modules, in conjunction with the control unit, is highly energy-efficient, minimizing unnecessary energy loss.

[0198] The first paper feeding module is used to feed the cardboard from the paper changer into the carton making machine for processing. The second paper feeding module is used to feed the processed cardboard out of the carton making machine.

[0199] The specific process is as follows: After the cardboard reaches the first paper feed module, the sun gear of the sun gear module drops and presses the cardboard. Then, the first paper feed module's paper feed motor drives the first paper feed roller via the synchronous pulley and the first synchronous belt mechanism. The cooperation between the first paper feed module's sun gear module and the paper feed motor ensures that the cardboard is accurately delivered to the desired position.

[0200] In implementation, such as Figure 4B 、 Figure 4C 、 Figure 4D and Figure 4E As shown, the sun gear module 323 - 1 includes:

[0201] An inverted U-shaped sun gear mounting frame 323 - 11 , wherein the vertical arm end of the sun gear mounting frame 323 - 11 has a downward-facing mounting opening 323 - 12 ;

[0202] A plurality of sun gears 323 - 13 and a sun gear mounting shaft 323 - 14 , wherein each of the sun gears 323 - 13 is evenly mounted on the sun gear mounting shaft 323 - 14 ;

[0203] A sun gear baffle 323 - 15 , wherein the sun gear baffle 323 - 15 has a sun gear baffle mounting hole;

[0204] Among them, the end of the sun gear mounting shaft 323-14 enters the mounting opening 323-12 from bottom to top, and then the sun gear baffle mounting hole passes through the end of the sun gear mounting shaft 323-14 and the sun gear baffle 323-15 is fixed to the outer side of the vertical arm of the sun gear mounting frame 323-11.

[0205] In this way, the cooperation of the sun gear mounting shaft 323-14, the mounting opening 323-12 at the end of the vertical arm of the sun gear mounting frame 323-11, and the sun gear baffle 323-15 enables quick installation and disassembly of the sun gear mounting shaft and the sun gear thereon, facilitating the subsequent replacement of a damaged sun gear.

[0206] Specifically, such as Figure 4B and Figure 4C As shown, the sun gear module 323 - 1 also includes:

[0207] The sun gear cylinder 323 - 16 is fixed to the outer top surface of the transverse arm of the sun gear mounting frame 323 - 11 to drive the sun gear mounting frame 323 - 11 to move up and down.

[0208] Each sun gear module has a separate sun gear cylinder, which enables the sun gear of each sun gear module to move up and down as a whole.

[0209] The structure of the cardboard silo is described below. Figure 5 As shown, the cardboard silo 1 includes multiple silos 11, a silo bracket 12, a residual material warning sensor 13, a sensor bracket 14, a cardboard guide belt 15, and a cardboard guide belt support shaft 16. The residual material warning sensor 13 is mounted below the silo bracket 12 via the sensor bracket 14. The silo is used to store entire stacks of continuously folded cardboard. The cardboard guide belt 15 and the cardboard guide belt support shaft 16 cooperate to achieve layered arrangement of cardboards of various widths.

[0210] The main advantage of the cardboard silo is that it has a cardboard residual early warning function. When the remaining cardboard level is lower than the residual early warning sensor 13, an alarm will be issued to remind the staff to replenish the cardboard.

[0211] The other structures of the box making machine are described below.

[0212] Specifically, the box making machine also includes a shell, an operation screen module, a paper pressing sheet metal module, a slotting and creasing module, and a paper discharge module.

[0213] The process of cardboard being processed into carton by carton making machine is as follows:

[0214] After the cardboard is fed into the box making machine by the paper changer, Figure 2B As shown, the first paper feeding module 321 continues to feed the cardboard forward, and the cardboard passes through the first transverse cutting module 331, the transverse slotting and creasing module 34, the longitudinal slitting and creasing module 30, the second paper feeding module 322, and the second transverse cutting module 332 in sequence.

[0215] When the preset length of the processed cardboard is greater than the distance between the first paper feeding module 321 and the second paper feeding module 322: when the cardboard entering the carton making machine is sufficient to complete a carton, the first transverse cutting module 331 cuts the cardboard. At this time, the first paper feeding module 321 no longer feeds paper, and the second paper feeding module 322 behind it mainly feeds paper.

[0216] After passing through the transverse slotting and creasing module, the cardboard reaches the longitudinal slitting and creasing module. This module also includes longitudinal creasing rollers spaced between the longitudinal creasing wheels, through which the cardboard passes. In the longitudinal slitting and creasing module, the cardboard undergoes longitudinal creasing, width trimming, and carton tongue processing.

[0217] The carton processing machine of this application has the following features in processing cartons:

[0218] 1. Processing flow: The carton making machine obtains the data information of the cartons to be processed. The PLC controls the carton making machine to adjust the tool position according to the data and controls the paper changer to select the most suitable cardboard. The cardboard passes from the cardboard hopper through the paper changer and enters the carton making machine. After the carton making machine goes through the processes of slotting, slitting, creasing, cutting and other processes, the carton production is completed.

[0219] 2. This carton processing machine is the first to integrate a cardboard hopper, a paper changer, and a carton making machine with slotting, creasing, and slitting functions.

[0220] 3. The advantages of this equipment are as follows:

[0221] (1) Save cardboard materials and select the cardboard with the highest utilization rate from a variety of specifications to avoid the waste of a single specification cardboard;
