Description

Technical Field

[0001] This utility model relates to the field of carton machine technology, and in particular to a transverse grooving and creasing device and processing components for a carton machine. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard box forming requires multiple processing steps, leading to the development of cardboard box forming machines on the market. These machines can complete a series of processes such as grooving, slitting, creasing, and punching in one go. However, most grooving mechanisms on the market currently use a lead screw drive, where the grooving blade moves linearly along the crossbeam under the drive of the lead screw. This not only results in unstable movement but also fails to meet production requirements in terms of precision. Furthermore, because the grooving blades are arranged horizontally side by side, the grooving length between two grooving blades cannot be minimized due to the size limitations of the blades themselves. Additionally, most sliding mechanisms on the market typically have multiple sliding blades sliding on a crossbeam, allowing for adjustable spacing between adjacent blades to adjust the sliding position. However, due to the size limitations of the blades themselves, the sliding distance between two adjacent blades cannot be minimized. Therefore, there is an urgent need for a device that can automatically perform transverse creasing, grooving, and sliding sequentially while minimizing the sliding distance. Utility Model Content

[0003] The purpose of this utility model is to design a transverse grooving and creasing device and processing components for a carton machine to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model provides a transverse grooving and creasing device for a carton machine, including a vertically movable crossbeam, a grooving knife connected to the crossbeam for grooving the cardboard to be processed, a drive mechanism for driving the grooving knife to slide, and a creasing knife connected to the crossbeam for creasing the cardboard to be processed. The drive mechanism includes a support member, a transmission structure located between the support member and the crossbeam, and a drive member mounted on the support member for driving the transmission structure. The grooving knife is connected to the support member and slides along the extension direction of the crossbeam under the drive of the drive mechanism. The creasing knife moves up and down under the drive of the crossbeam.

[0005] Preferably, the transmission structure includes a gear mounted on a support member and a gear mechanism arranged along the extension direction of the crossbeam and meshing with the gear member. The driving member is a servo motor, and the driving member is connected to the gear member to drive the gear member to rotate.

[0006] Further optimization involves adopting helical gear and helical rack structures for the gear components and tooth conditions.

[0007] Further optimization involves providing a guide rail structure parallel to the toothed surface on the crossbeam, a slider on the support member that slides in cooperation with the guide rail structure, and a grooving cutter connected to the slider.

[0008] In a further optimization, the indentation tool is connected to the crossbeam and located on top of the grooving tool, and the top of the grooving tool is provided with a clearance groove to avoid interfering with the sliding of the grooving tool.

[0009] Further optimization involves having at least two grooving cutters, which are grouped into at least one cutter group in pairs. Each grooving cutter is provided with two sliders, which are located at both ends of the grooving cutter, with one slider connected to a support member.

[0010] Further optimization involves installing individual drive components and gear components on each support, enabling each set of grooving cutters to operate independently.

[0011] In a further optimization, a connecting member is provided between the grooving cutter and the slider, with one end of the connecting member connected to the grooving cutter and the other end connected to the slider.

[0012] In a further optimization, the support component includes a base and a bottom plate. The bottom plate is vertically arranged, the connector is connected to the bottom plate, the base is connected to the top of the bottom plate, the drive component is mounted on the base, and the gear component is connected to the drive component.

[0013] Further optimization involves the cutting edge at the bottom of the grooving cutter being set at an angle from one end to the other.

[0014] Further optimization involves using four grooving cutters: a first grooving cutter, a second grooving cutter, a third grooving cutter, and a fourth grooving cutter arranged side-by-side along the crossbeam.

[0015] When two pieces of cardboard are conveyed side by side to the bottom of the crossbeam, the first and second grooving knives groove the two sides of one of the cardboard pieces, and the third and fourth grooving knives groove the two sides of the other cardboard piece.

[0016] When a piece of cardboard is conveyed to the bottom of the crossbeam, any two adjacent grooving blades will groove both sides of the cardboard.

[0017] When a piece of cardboard is conveyed to the underside of the crossbeam, the second and third grooving knives approach each other to combine into a single grooving knife to groove the center of the cardboard, while the first and fourth grooving knives groove the cardboard from both sides.

[0018] Further optimization involves using three grooving cutters, specifically any three of the following: a first grooving cutter, a second grooving cutter, a third grooving cutter, and a fourth grooving cutter arranged side-by-side along the crossbeam.

[0019] When a piece of cardboard is conveyed to the bottom of the crossbeam, the grooving knife in the middle grooves the center of the cardboard, while the two grooving knives on the sides groove the sides of the cardboard respectively.

[0020] This utility model also provides a processing assembly, including a frame, on which:

[0021] The paper feeding assembly includes a first baffle, a second baffle, a third baffle, and a fourth baffle that are arranged horizontally side by side and can reciprocate along the horizontal direction;

[0022] The aforementioned carton machine uses a transverse slotting and creasing device to creasing and slot the cardboard.

[0023] Preferably, when two cardboard sheets are conveyed side by side, the first and second baffles limit the sides of one cardboard sheet, and the third and fourth baffles limit the sides of the other cardboard sheet; or the first and second baffles limit the sides of one cardboard sheet, and the second and third baffles limit the sides of the other cardboard sheet; or the second and third baffles limit the sides of one cardboard sheet, and the third and fourth baffles limit the sides of the other cardboard sheet, so that the two cardboard sheets are conveyed side by side to below the corresponding slotting knife;

[0024] When a piece of cardboard is conveyed, any two adjacent baffles limit the two sides of the cardboard so that the cardboard is conveyed to the bottom of the corresponding slotting knife.

[0025] Preferably, the frame is also provided with a longitudinal cutting assembly, which includes at least two longitudinal cutting mechanisms distributed in a front-to-back manner. Each longitudinal cutting mechanism includes at least two bases that can move laterally back and forth and longitudinal cutting blades correspondingly mounted on the bases.

[0026] Further optimization involves using a circular blade type longitudinal cutter and / or a vibrating longitudinal cutter.

[0027] Further optimization involves conveying the cardboard along the feeding assembly, the transverse slotting and creasing device of the carton machine, and the longitudinal cutting assembly to feed, transversely creasing and slotting, and longitudinally cutting the cardboard.

[0028] The technical advantage of this utility model is that the grooving cutter is mounted on the crossbeam through a drive mechanism, enabling the grooving cutter to reciprocate along the extension direction of the crossbeam to achieve the grooving cutter's operation. In this utility model, the transmission structure of the drive mechanism preferentially adopts a servo motor driving a helical gear and helical rack structure. The rotational motion of the gear is converted into the linear motion of the grooving cutter through the helical gear and helical rack structure. The servo motor can accurately control the movement accuracy of the grooving cutter, while the helical gear and helical rack structure makes the movement of the grooving cutter more stable, thereby improving the grooving efficiency and reducing the defect rate.

[0029] Multiple grooving cutters are arranged in parallel on the crossbeam. Since the height of the grooving cutters is high at one end and low at the other, the higher end of two adjacent grooving cutters can be set opposite each other or far apart. This allows the higher end of the grooving cutter 2 to be moved to the outermost side, which widens the distance between two adjacent grooves and meets the requirement of maximizing the horizontal groove spacing.

[0030] The longitudinal cutting assembly includes at least two longitudinal cutting mechanisms distributed front to back, that is, the two longitudinal cutting blades are staggered and not on the same straight line. In this way, the distance between the two cutting points of the two longitudinal cutting blades can be adjusted. Compared with the cutting of two longitudinal cutting blades distributed side by side in the conventional direction, the lower limit of the distance between the two longitudinal cutting blades in the same direction cannot be reached due to the width of the longitudinal cutting blades themselves. That is, it is limited by the size of the longitudinal cutting blades themselves. However, the longitudinal cutting blades distributed front to back can achieve a distance smaller than the size of the longitudinal cutting blades themselves. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0048] This utility model includes a crossbeam 1, a grooving knife 2, a drive mechanism, a guide mechanism, and a creasing knife 3. The grooving knife 2 is slidably connected to the crossbeam 1 through the combined action of the drive mechanism and the guide mechanism. The crossbeam 1 can move up and down relative to the carton machine body. The creasing knife 3 is installed on the crossbeam 1 and moves up and down with the crossbeam 1. When the grooving knife 2 moves up and down with the crossbeam 1, it also slides laterally to achieve lateral grooving.

[0049] The driving mechanism includes a support member 4, a transmission structure, and a driving member 5. In this embodiment, the transmission structure is a gear and rack structure, which includes a gear member 6 and a gear condition 7. The gear member 6 is mounted on the support member 4, and the gear condition 7 is arranged along the extension direction of the crossbeam 1 and meshes with the gear member 6 to achieve transmission. The driving member 5 is mounted on the support member 4 and its output end is connected to the gear member 6 to drive the gear member 6 to rotate, thereby enabling the support member 4 to achieve transmission through the gear and rack structure. The guiding mechanism includes a guide rail structure 8 and a slider 9. The guide rail structure 8 is arranged along the extension direction of the crossbeam 1 and fixed on the crossbeam 1. In this embodiment, the guide rail structure 8 and the gear condition 7 are arranged parallel to each other on the crossbeam 1, and the slider 9 is slidably engaged with the guide rail structure 8, so that the support member 4 can reciprocate along the extension direction of the crossbeam 1 under the joint cooperation of the driving structure and the guiding mechanism.

[0050] In addition, the transmission structure can also adopt other mechanical transmission structures such as belts, chains, lead screw pairs or worm gears.

[0051] Furthermore, the drive component 5 adopts a servo motor, and the gear component 6 and gear condition 7 adopt a helical gear structure and a helical rack structure. Compared with other transmission structures, the servo motor drives the helical gear rack structure to transmit torque after amplifying the torque through its own reducer, so that the rotational motion of the servo motor is converted into the linear motion of the cross-cutting blade. This can ensure the accuracy of the support component 4 when moving linearly, and at the same time ensure the stability of the movement.

[0052] The grooving knife 2 is connected to the support member 4 via the slider 9. That is, the grooving knife 2 is connected to the slider 9, and the slider 9 is connected to the support member 4. The drive mechanism drives the support member 4 to move, and the support member 4 drives the grooving knife 2 to slide along the extension direction of the crossbeam 1 to groove and creasing the cardboard.

[0053] In this embodiment, the grooving knife 2 is connected to the slider 9 and distributed along the extension direction of the crossbeam 1. The top of the grooving knife 2 is provided with a relief groove 22, which is set along the extension direction of the grooving knife 2. The indentation knife 3 is fixed on the crossbeam 1 and extends into the relief groove 22. When the grooving knife 2 moves back and forth along the indentation knife 3 under the drive of the support member 4, the grooving knife 2 slides along the crossbeam 1 to perform grooving, while the indentation knife 3 moves up and down through the crossbeam 1 to perform indentation. In this embodiment, when the indentation knife 3 extends into the relief groove 22, it does not contact the inner wall of the relief groove 22. The relief groove 22 only plays a relief role. Of course, the indentation knife 3 can contact the inner wall of the relief groove 22, and the grooving knife 2 can slide along the relief groove 22, as long as it does not interfere with the sliding of the grooving knife 2.

[0054] The number of grooving blades 2 is at least two. The grooving blades 2 are divided into at least one group of blades in pairs. Multiple groups of grooving blades 2 can be arranged in a square along the extension of the crossbeam 1 to achieve batch grooving. In this embodiment, there are two groups of grooving blades 2, which are symmetrically arranged along the extension direction of the crossbeam 1 and respectively grooving the two sides of the cardboard to be processed. Each grooving blade 2 is provided with two sliders 9. The two sliders 9 are located at both ends of the grooving blade 2 and connected to the grooving blade 2. One slider 9 is connected to a support member 4, so that the grooving blade 2 can move stably by being driven by the support member 4. Each support member 4 is provided with a separate drive member 5 and gear structure, so that each group of grooving blades 2 can work independently. Therefore, each group of grooving blades 2 does not interfere with each other and has better flexibility.

[0055] Furthermore, such as Figure 6 and 7 As shown, there are four grooving cutters 2, namely the first grooving cutter 26, the second grooving cutter 27, the third grooving cutter 28, and the fourth grooving cutter 29. The four grooving cutters 2 are arranged side by side along the crossbeam 1 and can slide back and forth laterally. In this embodiment, the four grooving cutters have the following cooperation processing methods:

[0056] In the first case, when two cardboard sheets are processed at the same time, the two cardboard sheets are conveyed side by side to the bottom of the crossbeam. The first grooving knife 26 and the second grooving knife 27 grooves the two sides of one cardboard sheet, and the third grooving knife 28 and the fourth grooving knife 29 grooves the two sides of the other cardboard sheet. That is, the four grooving knives groove the two sides of the corresponding cardboard sheets in pairs.

[0057] The second method is to process only one piece of cardboard. The cardboard is conveyed to the bottom of the crossbeam 1, and any two adjacent grooving knives 2 groove both sides of the cardboard. That is, only one piece of cardboard needs to be grooved. Any two adjacent grooving knives 2, namely the first grooving knife 26 and the second grooving knife 27, the second grooving knife 27 and the third grooving knife 28, or the third grooving knife 28 and the fourth grooving knife 29, directly groove both sides of the cardboard.

[0058] The third method involves processing only one sheet of cardboard. The cardboard is conveyed below the crossbeam 1, and the second grooving blade 27 and the third grooving blade 28 approach each other, their opposite ends fitting together to form a single grooving blade 2. This blade, when joined together, creates a single grooving blade 2, grooving the middle of the cardboard and forming a complete groove. The first grooving blade 26 and the fourth grooving blade 29 then groove the cardboard from both sides. The cardboard continues to be conveyed to the longitudinal cutting mechanism, which longitudinally cuts the cardboard between the two parallel grooves, dividing it into two identical pieces.

[0059] Furthermore, the above is a processing example with four grooving blades 2. Of course, the number of grooving blades 2 can also be three, that is, three grooving blades 2. The grooving work is similar to the third case above. When processing only one piece of cardboard, the cardboard is conveyed to the bottom of the crossbeam 1. The grooving blade 2 located in the center grooves the center of the cardboard, so that a groove is formed in the center. The grooving position of the grooving blade 2 is quite diverse. For example, it can be grooved in the exact center of the cardboard, or it can be offset to both sides. At the same time, the length of the grooving can be adjusted by adjusting the lateral position of the grooving blade 2. That is, the grooving blade 2 moves to the preset starting position and then presses down, then rises and moves laterally to the preset ending position and presses down, and then grooves between the two positions, which is the length of the groove. In short, the design of three grooving blades 2 is very flexible and can meet the requirements of different groove positions. The grooving blades 2 located on both sides groove the two sides of the cardboard. Then the cardboard continues to be conveyed to the longitudinal cutting mechanism. The longitudinal cutting mechanism longitudinally cuts the cardboard between the two parallel grooves, cutting the cardboard into two identical cardboards.

[0060] Furthermore, the grooving cutter 2 includes a cutter body 23, the length direction of the cutter body 23 is along the left-right direction and the thickness direction is along the front-back direction. A grooving blade is provided on the lower side of the cutter body 23. Specifically, the grooving blade is inclined from the lower right to the upper left.

[0061] The tool body 23 has a starting cutter head 24 on the lower right side, that is, the starting cutter head 24 is located at the inclined lower end of the grooving edge. The starting cutter head 24 extends downward and a starting cutting edge 241 is formed at the bottom of the starting cutter head 24, which is downward and narrows along the thickness direction of the tool body 23.

[0062] The tool body 23 has an end cutter head 25 on the lower left side, that is, the end cutter head 25 is located at the inclined upper end of the grooving edge. The end cutter head 25 extends downward and an end cutting edge 251 is formed at the bottom of the end cutter head 25.

[0063] When two adjacent grooving knives 2 approach and fit together, in this embodiment, the two adjacent grooving knives 2 are the second grooving knife 27 and the third grooving knife 28. Since the bottom of the starting blade 24 has a starting blade 241, when the starting blades 24 of the two grooving knives fit together, the starting blades 241 of the two adjacent knives fit together accordingly to form a spliced ​​starting blade 241, so that the two grooving knives can move down synchronously to perform grooving work. That is, when the second grooving knife 27 and the third grooving knife 28 fit together, they can be used as a grooving knife 2 to perform grooving. In this embodiment, since the second grooving knife 27 and the third grooving knife 28 are located in the central position, they move down to perform grooving work after fitting together. The groove is a closed groove in the center of the cardboard. Therefore, the grooving knife 2 in this utility model is very flexible and can make closed or open grooves.

[0064] It should be noted that commercially available transmission structures use lead screws. When a set of grooving cutters 2 are arranged side by side on the crossbeam 1, two lead screws need to be set in parallel to control the reciprocating sliding of the corresponding grooving cutter. However, due to the limited installation position of the two parallel lead screws, when the two grooving cutters 2 move along the extension direction of the crossbeam 1, the grooving cutter 2 cannot cross the midpoint between the two grooving cutters 2 and slide to the other half. This utility model is different. The transmission structure uses a rack and pinion, which is set along the entire extension direction of the crossbeam 1. Each grooving cutter 2 is equipped with a driving component 5. When one grooving cutter 2 moves to one end of the crossbeam 1, the other grooving cutter can directly cross the midpoint and move to the other half of the crossbeam 1. In other words, when using a gear and rack transmission structure, the movement of two or more grooving cutters 2 is more flexible.

[0065] Furthermore, a connector 10 is provided between the grooving cutter 2 and the slider 9. The connector 10 is a bent block structure. One end of the connector is detachably connected to the grooving cutter 2 by a fastener, and the other end is detachably connected to the slider 9 by a fastener, so that they can be detached from each other, making it easy to load and unload the grooving cutter 2 and the slider 9. One of the sliders 9 is provided with a support 4, so that the entire grooving cutter 2 can be driven by the support 4.

[0066] Furthermore, the support member 4 includes a base 41 and a bottom plate 42. The bottom plate 42 is vertically arranged. The slider 9 is connected to one side of the bottom plate 42 by fasteners. The base 41 is connected to the top of the bottom plate 42. The drive member 5 is installed on the base 41. The gear member 6 is rotatably connected to the bottom of the base 41 and connected to the output end of the drive member 5.

[0067] It should be noted that the cutting edge 21 at the bottom of the grooving cutter 2 is inclined from one end to the other. When the grooving cutter 2 slides laterally along the crossbeam 1, the crossbeam 1 moves downward at the same time, so that the grooving cutter 2 grooves laterally from one end to the other.

[0068] The crossbeam 1 is installed on the carton machine body through a vertical moving mechanism, which enables the crossbeam 1 to move up and down.

[0069] This utility model also provides a processing assembly, which includes: a paper feeding assembly 11, including a leading edge paper feeder 111 for supporting and conveying paperboard and a feeding group 112 located above the paper feeder, the feeding group 112 being used to limit the paperboard stacked on the leading edge paper feeder 111 and allowing only a single sheet of paperboard to advance; the aforementioned transverse grooving and creasing device for carton machines for creasing and grooving the paperboard; and a longitudinal cutting assembly 12, including at least two longitudinal cutting mechanisms distributed front to back, the longitudinal cutting mechanism including at least two bases 121 capable of transverse reciprocating movement and longitudinal cutting blades correspondingly mounted on the bases 121.

[0070] The leading edge feeder 111 includes a support platform 1111 located in front of the crossbeam 1. The support platform 1111 has multiple ventilation holes 1113 evenly distributed on it. A drive roller 1112 is located in front of the ventilation holes 1113 on the support platform 1111. The drive roller 1112 is arranged laterally, and the paperboard is placed directly above the ventilation holes 1113. The drive roller 1112, located at the bottom front of the paperboard, allows air to pass through... The cardboard is conveyed by rotation; in addition, the support platform 1111 is provided with air extraction holes 1114, which are also evenly distributed on the support platform 1111. In this embodiment, a number of air extraction holes 1114 are evenly distributed at the edge of the support platform 1111. The air extraction holes 1114 are connected to an external vacuum device. The vacuum device evacuates the air extraction holes 1114 to form a negative pressure, which forms a certain adsorption on the cardboard during the cardboard conveying process, so that the cardboard can move forward smoothly.

[0071] The feeding assembly 112 includes an installation beam 1121 arranged in the same direction as the crossbeam 1. A limiting plate 1122 is provided on the installation beam 1121. The limiting plate 1122 faces the direction of the front edge feeder 111 and is vertically arranged relative to the support platform 1111. The limiting plate 1122 can be adjusted up and down along the height direction of the installation beam 1121, and can also move back and forth along the length direction of the installation beam 1121, thereby achieving lateral position adjustment. The lateral movement and up and down movement of the limiting plate 1122 are both achieved through a screw drive structure, so that there is a gap between the bottom end of the limiting plate 1122 and the surface of the support platform that allows only a single sheet of paperboard to pass through, so that the paperboard is conveyed forward in an orderly manner under the transmission of the front edge feeder 111.

[0072] The mounting beam 1121 has baffles 1123 on both sides of the limiting plate 1122. Each baffle 1123 has a slider structure, and the mounting beam 1121 has a slide rail structure that slides in conjunction with the slider structure. This allows the baffles 1123 to slide back and forth along the transverse line of the mounting beam 1121, ultimately achieving adjustable spacing between the two baffles 1123. This accommodates cardboard of different lengths. When multiple cardboard sheets are stacked, the baffles 1123 shield the stacked cardboard sheets from both sides, ensuring that the stacked cardboard sheets are aligned. Then, the limiting plate 1122 controls the movement of each cardboard sheet, allowing them to pass through and be conveyed to the next assembly individually. It should be noted that the limiting plate 1122 is typically located in the center between the two baffles 1123. The two baffles 1123 limit the lateral movement of the stacked cardboard sheets on both sides, preventing lateral displacement, while the limiting plate 1122 further limits movement from the center, ensuring stable transmission of the cardboard sheets.

[0073] In this embodiment, there are four baffles 1123. When two cardboard sheets are conveyed side by side, the first baffle 11231 and the second baffle 11232 limit the two sides of one cardboard sheet, and the third baffle 11233 and the fourth baffle 11234 limit the two sides of the other cardboard sheet; or the first baffle 11231 and the second baffle 11232 limit the two sides of one cardboard sheet, and the second baffle 11232 and the third baffle 11233 limit the two sides of the other cardboard sheet; or the second baffle 11232 and the third baffle 11233 limit the two sides of one cardboard sheet, and the third baffle 11233 and the fourth baffle 11234 limit the two sides of the other cardboard sheet, so that the two cardboard sheets are conveyed side by side to the bottom of the corresponding grooving knife;

[0074] When a piece of cardboard is conveyed, any two adjacent baffles 1123 limit the two sides of the cardboard to ensure that the cardboard is conveyed below the corresponding slotting knife.

[0075] Furthermore, the first baffle 11231 and the fourth baffle 11234 are typically set to automatically adjust and slide, while the second baffle 11232 and the third baffle 11233 are set to manually adjust and slide, so that the spacing between the four baffles 1123 can be flexibly adjusted to adapt to different cardboard conveying.

[0076] In this embodiment, the longitudinal cutter is a circular cutter 122 and / or a vibrating longitudinal cutter 1211.

[0077] When the longitudinal cutter uses a circular cutter type 122, the longitudinal cutting mechanism includes a base 121 that is laterally slidably connected to the frame. A cutter holder 123 is mounted on the base 121 and rotatably connected to the base 121. The cutter holder 123 is a plate-like structure vertically fixed to the bottom of the base 121. A transmission wheel assembly is mounted on the cutter holder 123. The transmission wheel assembly includes a driven wheel 125 and a driving wheel 126 located at the front and rear of one side of the cutter holder 123. That is, the driven wheel 125 and the driving wheel 126 move along... The base 121 is horizontally distributed front and back, and the central axes of the driven wheel 125 and the driving wheel 126 are staggered at different heights. In this embodiment, the driving wheel 126 is fixedly positioned higher than the driven wheel 125. The driving wheel 126 is connected to the driven wheel 125 via a belt and drives the driven wheel 125 to rotate. The belt is located on one side of the driving wheel 126 and the driven wheel 125. The driving wheel 126 is rotatably connected to the tool holder 123 via a key shaft. The driven wheel 125 is provided with a disc-shaped longitudinal cutting blade on its outer periphery.

[0078] The frame is provided with a first guide rail that extends laterally and is horizontally arranged. The base 121 is provided with a first slider 128 that slides and engages with the first guide rail. The frame is provided with a first rack structure 129 that is in the same direction as the first guide rail. The base 121 is provided with a first gear structure 1210 that engages with the first rack structure 129. The base 121 is also provided with a first driving member that drives the first gear structure 1210 to rotate. The first driving member drives the first gear structure 1210 to move along the first rack structure 129. The guiding effect of the cooperation between the first guide rail and the first slider 128 makes the translational stability of the base 121 stable.

[0079] A telescopic rod 124 is provided between the blade holder 123 and the base 121. In this embodiment, the rod 124 includes a driving component, which is a telescopic motor or a telescopic cylinder. Its fixed end is hinged to the base 121, and its telescopic end is hinged to the blade holder 123. Since the blade holder 123 is rotatably connected to the base 121, the rod 124 extends and retracts, causing the blade holder 123 to swing back and forth, thereby driving the driven wheel 125 to move up and down, thus realizing the up and down movement of the longitudinal cutter to control the operation of the longitudinal cutter and adjust the cutting depth of the longitudinal cutter.

[0080] When the longitudinal cutter uses a vibrating longitudinal cutter 1211, the structure of the base 121 is the same as that of the circular cutter 122 described above, except that the longitudinal cutting blade uses a vibrating blade. The specific structure and working principle will not be described in detail here.

[0081] In this embodiment, the longitudinal cutting component 12 includes at least two longitudinal cutting mechanisms arranged in a front-to-back configuration. Each longitudinal cutting mechanism has at least two longitudinal cutting blades along the transverse direction, allowing the spacing between adjacent longitudinal cuts to be adjusted in the same transverse direction. The front-to-back arrangement of the longitudinal cutting mechanisms means that the two longitudinal cutting blades are staggered, i.e., not on the same straight line. This allows the spacing between the two points cut by the two longitudinal cutting blades to be adjustable. Compared to the conventional cutting of two longitudinal cutting blades arranged side by side in the transverse direction, the lower limit of the spacing between the two longitudinal cutting blades in the same transverse direction cannot be reached due to the width of the longitudinal cutting blades themselves, i.e., it is limited by the size of the longitudinal cutting blades themselves. However, the front-to-back arrangement of longitudinal cutting blades can achieve a spacing smaller than the size of the longitudinal cutting blades themselves.

[0082] Furthermore, the longitudinal cutter is either a circular cutter 122 or a vibrating longitudinal cutter 1211. Therefore, the longitudinal cutters of the two longitudinal cutting mechanisms can be arranged in a combination of circular cutter 122 and vibrating longitudinal cutter 1211. In this embodiment, the longitudinal cutter on one longitudinal cutting mechanism is a circular cutter 122, and the longitudinal cutter on the other longitudinal cutting mechanism is a vibrating longitudinal cutter 1211; or both circular cutter 122 and vibrating longitudinal cutter 1211 can be simultaneously provided on the same longitudinal cutting mechanism. In this embodiment, for example... Figure 8 and 9As shown, four longitudinal cutting blades are arranged on the same longitudinal cutting mechanism. The four longitudinal cutting blades include two circular longitudinal cutting blades 122 and two vibrating longitudinal cutting blades 1211. The two vibrating longitudinal cutting blades 1211 are located between the two circular longitudinal cutting blades 122. That is, an adjacent vibrating longitudinal cutting blade 1211 and a circular longitudinal cutting blade 122 form a longitudinal cutting group. Thus, two longitudinal cutting groups are formed on each longitudinal cutting mechanism to meet different longitudinal cutting requirements.

[0083] It should be noted that the cardboard is conveyed along the paper feeding assembly 11, the transverse slotting and creasing device of the carton machine and the longitudinal cutting assembly 12 to feed the cardboard, perform transverse creasing and slotting and longitudinal cutting, that is, to process it in sequence.

[0084] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
