Description

[0002] The carton machine is a device capable of automatically producing cartons, which generally comprises a paper feeding support, a slotting cutter, a line hitting beam, a longitudinal pressing wheel, a longitudinal cutting cutter, a transverse cutting cutter (with a gluing unit), a handle hole module and other components, and can complete the processes of paper feeding, slotting, cutting, line pressing, edge trimming, printing, gluing and punching at one time.

[0003] Taking a common cuboid carton as an example, after a single paperboard is processed by the carton machine, a transverse slot, a transverse score line, a longitudinal score line and a handle hole can be processed on the paperboard, a tongue part for bonding can be cut, and adhesive can be applied to the tongue part, and after folding and box bonding, the carton can be put into use.

DETAILED DESCRIPTION

[0097] In order to make the person skilled in the art better understand the present application scheme, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0098] As Figure 1 shown, Figure 1 is a structural schematic diagram of the carton machine in the present embodiment.

[0099] The carton machine in the embodiment mainly comprises a paper feeding mechanism 100, a slotting mechanism 200, a line pressing wheel mechanism 300, a longitudinal cutter mechanism 400 and a transverse cutter mechanism 500 arranged in sequence along the longitudinal direction, and the paperboard to be processed into a carton can be fed into the carton machine by the paper feeding mechanism 100, be slotted by the slotting mechanism 200 first, be pressed by the line pressing wheel mechanism 300, and then be trimmed in the longitudinal direction and the transverse direction by the longitudinal cutter mechanism 400 and the transverse cutter mechanism 500 respectively, and the longitudinal direction and the transverse direction are perpendicular to each other, and finally the paperboard is formed with a notch and a press line, and then a required three-dimensional carton structure can be formed through folding and bonding operations.

[0100] As shown in Figures 2-4 The paper feeding mechanism comprises a paper feeding beam 101, an adjusting part 103 and four guide plates 102, wherein two ends of the paper feeding beam 101 are respectively provided with two support seats for supporting the paper feeding beam, and the beam 101 is further provided with a slide rail 111 along the length direction, the four guide plates 102 are arranged in parallel along the length direction of the slide rail 111, and each guide plate 102 can slide along the length direction of the slide rail 111, and the adjacent two guide plates 102 can enclose a paper feeding channel 104, and the length direction of the slide rail 111 is perpendicular to the feeding direction of the paperboard 01 along the paper feeding channel 104.

[0101] The paper feeding mechanism further comprises a workbench, the support seat is arranged on the workbench, and a blocking piece 105 is arranged in the paper feeding channel 104, the blocking piece 105 is used for limiting the thickness of the paperboard 01 passing through the paper feeding channel 104, the adjusting part 103 is used for adjusting the height of the blocking piece 105, so that the spacing between the blocking piece 105 and the upper surface of the workbench is adapted to the thickness of the single paperboard 01 of different specifications, and then the single paperboard 01 is sequentially released to enter the carton machine from the paper feeding channel 104. The blocking piece 105 can also slide along the length direction of the slide rail 111 to avoid hindering the sliding of the guide plate 102.

[0102] The bottom of the guide plate 102 is provided with a matching structure matched with the workbench, and when the guide plate 102 slides along the slide rail 111, it can stably adhere to the table surface of the workbench to provide better guiding effect for the paperboard 01. Specifically, the matching structure at the bottom of the guide plate 102 is not limited, and can be set according to the specific structure of the workbench.

[0103] Each guide plate 102 can slide along the slide rail 111, so that different paper feeding modes can be formed, as shown in Figure 3 One paper feeding mode is to use only two adjacent guide plates 102 to form a paper feeding channel 104, and this paper feeding mode is suitable for processing paperboards 01 of the same specification.

[0104] As shown in Figure 2As shown, the four guide plates 102 can be divided into two groups respectively, and one paper feeding channel 104 is formed between the two guide plates 102 of each group, so that a double-channel paper feeding mode can be formed, and this mode can realize the simultaneous processing of two groups of paper boards 01.

[0105] By adjusting the sliding of each guide plate 102 along the slide rail 111, when the widths of the two paper feeding channels 104 are the same (here, the width of the paper feeding channel 104 refers to the size in the length direction of the slide rail 111), the same specification of paper boards 01 can be fed along the two channels 104 respectively, effectively improving the processing efficiency of the paper boards 01, and further improving the forming efficiency of the carton.

[0106] When the widths of the two paper feeding channels 104 are different, the two paper feeding channels 104 can be used for feeding paper boards 01 of different specifications respectively, which is efficient and can effectively improve the processing flexibility of the carton machine.

[0107] That is, through the paper feeding mechanism provided in the embodiment, single-channel paper feeding, double-channel paper feeding of the same specification of paper boards 01, and simultaneous paper feeding of two different specifications of paper boards 01 can be realized. This makes the processing flexibility of the carton machine better, and can effectively improve the forming efficiency of the carton.

[0108] In the embodiment, three paper feeding channels 104 can also be formed between the four guide plates 102, and the widths of the three paper feeding channels 104 can be completely the same, partially the same, or completely different.

[0109] In other embodiments, the number of guide plates 102 can also be three, five or more, which is not specifically limited here. Each guide plate 102 can slide in the length direction of the slide rail 111 and have the ability to realize double-channel or multi-channel paper feeding at the same time. For convenience of description, the number of guide plates 102 is taken as four in the description.

[0110] It is not difficult to understand that the paper feeding mechanism is only the entrance of the paper boards 01 of the carton machine, and the arrangement of the paper feeding channels 104 of the paper feeding mechanism needs to correspond to the setting of the subsequent processing mechanism of the carton machine.

[0111] That is, the paper feeding mechanism provided in the embodiment can realize single-channel paper feeding, double-channel or multi-channel paper feeding, and when double-channel or multi-channel paper feeding is performed, the same specification of paper boards 01 can be fed, or different specifications of paper boards 01 can be fed, which is flexible and has high carton forming efficiency.

[0112] In the embodiment, part of the guide plates 102 are electric guide plates 121, and part of the guide plates 102 are manual guide plates 122. The paper feeding mechanism further comprises a driving part 106 for driving the electric guide plates 121 to slide along the slide rails 111. Specifically, the driving part 106 comprises a motor 161 and a screw rod 162. The motor 161 is arranged on the support seat, and the screw rod 162 is arranged in parallel with the slide rails 111. The electric guide plates 121 are provided with a nut 163 matched with the screw rod 162.

[0113] The manual guide plates 122 are manually driven by the operator, so that the manual guide plates 122 slide along the slide rails 111, and as shown in Figure 4 and Figure 5 The manual guide plates 122 are further provided with a sliding block 123 and a fixing part 1221. The sliding block 123 can slide along the slide rails 111, and the fixing part 1221 can fix the relative position of the sliding block 123 and the slide rails 111. When the manual guide plates 122 need to slide along the slide rails 111, the fixing part 1221 is manually operated, so that the sliding block 123 can slide along the slide rails 111. When the manual guide plates 122 are moved to the required position along the slide rails 111, the fixing part 1221 can be manually operated, so that the position of the sliding block 123 and the slide rails 111 is relatively fixed.

[0114] In the embodiment, the specific structure of the fixing part 1221 is not limited, which can be a manual clamp, a fixed clamp, etc.

[0115] Of course, in the embodiment, all the guide plates 102 can be electric guide plates 121, or all the guide plates 102 can be manual guide plates 122. When part of the guide plates 102 are electric guide plates 121 and part of the guide plates 102 are manual guide plates 122, the position adjustment operation of the guide plates 102 can be simplified, and the width of the paper feeding channel 104 can be finely adjusted by the manual guide plates 122. When there is a width error in the paperboard 01, the distance between the guide plates 102 can be quickly adjusted by manual operation, so as to adapt to the actual width of the paperboard 01.

[0116] Specifically, in the embodiment, the number of the electric guide plates 121 and the manual guide plates 122 is not limited, as shown in Figure 2 and Figure 3 The number of the electric guide plates 121 is set to two, and the number of the driving parts 106 is also two. The screw rods 162 of the two driving parts 106 are arranged in parallel or coaxially. The paper feeding cross beam 101 is further provided with a bearing seat 112, which is installed with two bearings. One end of each screw rod 162 is in transmission connection with the motor 161, and the other end of the screw rod 162 is connected with one bearing, so as to ensure the driving stability.

[0117] That is to say, each electric guide plate 121 can move within the length range of the lead screw 162. Two motors 161 are respectively located at the two ends of the paper feeding beam 101, and the specific motor 161 can be fixed with the paper feeding beam 101 or fixed with the support seat. Such arrangement makes the overall structure more compact.

[0118] The two side ends of the paper feeding beam 101 are also respectively provided with a connecting seat 113, the connecting seat 113 is also provided with a bearing, and the side of the lead screw 162 towards the motor 161 is connected with the connecting seat 113 through a bearing, further ensuring the stability of the rotation of the lead screw 162.

[0119] The number of manual guide plates 122 is also two, and the two electric guide plates 121 are located between the two manual guide plates 122. Specifically, in use, it can be adjacent to one group of electric guide plates 121 and manual guide plates 122, and the electric guide plates 121 are controlled to move by the motor 161 and cooperate with the positions of the manual guide plates 122 to form a paper feeding channel 104, realize the double-channel paper feeding mode as shown in Figure 1 , or it can form a paper feeding channel 104 between the two electric guide plates 121 to realize the single-channel paper feeding mode as shown in Figure 3 , or it can form a paper feeding channel 104 between the electric guide plates 121 and the manual guide plates 122 and between the two electric guide plates 121 respectively to realize a three-channel paper feeding mode.

[0120] At least part of the electric guide plates 121 is a guide plate 102 that can realize quick disassembly. Specifically, the rear end of this part of the electric guide plate 121 is connected with a sliding plate 1211 through a bolt, the sliding plate 1211 is fixed with the above-mentioned nut 163, and the sliding plate 1211 is also provided with a sliding block 123 that can slide along the sliding rail 111. In this paper, "front" and "rear" are set according to the paperboard 01 feeding direction, and the paperboard 01 can enter the carton machine from the front to the rear from the paper feeding channel 104.

[0121] The sliding plate 1211 and the electric guide plate 121 are connected through a bolt, which facilitates the disassembly and assembly operation of the electric guide plate 121. When the paperboard 01 is large in size and the required paper feeding channel 104 is large in width, part of the guide plate 102 can be disassembled, as shown in Figure 3 , at this time, the sliding plate 1211 is not disassembled, and the baffle 107 is also disassembled with the electric guide plate 121, which reduces the space occupied by the electric guide plate 121 on the sliding rail 111, and facilitates the formation of a paper feeding channel 104 with a larger width, which is good in flexibility.

[0122] In the embodiment, some of the electric guide plates 121 can be capable of quick release, some of the electric guide plates 121 can not be capable of quick release, or all of the electric guide plates 121 can be capable of quick release. The electric guide plates 121 that are not capable of quick release and the slide plate 1211 can be provided in an integrated structure.

[0123] In the embodiment, the number of the slide rails 111 can be one or two. Two slide rails 111 are arranged in parallel along the height direction. The slide plate 1211 is provided with two sliding blocks 123 that can correspond to the two slide rails 111 respectively. The arrangement of the two slide rails 111 can improve the stability of the sliding of the guide plate 102.

[0124] As shown in Figure 6 , the adjusting part 103 further comprises a baffle 107. The baffle 107 is connected with the guide plate 102 and can move up or down along the height direction relative to the guide plate 102. The baffle 107 can also slide along the slide rail 111 under the driving of the guide plate 102. The baffle 107 extends out of the side wall of the guide plate 102 and forms the above-mentioned stop piece 105. That is, in the embodiment, the stop piece 105 is connected with the guide plate 102 and slides along the slide rail 111 with the guide plate 102. In this way, compared with the scheme that the stop piece 105 and the guide plate 102 slide along the slide rail 111 respectively, the overall structure can be simplified.

[0125] As shown in Figure 6 , the side surface of the baffle 107 and the side surface of the guide plate 102 are perpendicular to each other. The side edge of the baffle 107 can extend out of the side wall of the guide plate 102 and form the stop piece 105. In this way, the structure of the stop piece 105 can be simplified.

[0126] Further, the baffle 107 and the guide plate 102 are connected in the height direction by insertion connection. After the insertion connection, the baffle 107 can also move up and down relative to the guide plate 102. Of course, in the embodiment, the connection mode between the baffle 107 and the guide plate 102 is not limited. For example, the guide plate 102 can be provided with a strip-shaped hole arranged in the height direction. The baffle 107 can be connected with the strip-shaped hole by a connecting bolt. The insertion connection mode can simplify the overall structure and processing technology and is convenient for disassembly and assembly.

[0127] Further, as shown in Figure 4 and Figure 5 , the adjusting part 103 comprises an adjusting shaft 131 and an eccentric cam 132. The adjusting shaft 131 is parallel to the slide rail 111. The eccentric cam 132 can slide along the axial direction of the adjusting shaft 131 and can rotate coaxially with the adjusting shaft 131. The baffle 107 is provided with a matching groove 171. Specifically, as shown in Figure 6As shown, the baffle 107 is fixed with a connecting piece 172, which is provided with a matching groove 171, and the eccentric cam 132 is located in the matching groove 171, and the rotation of the adjusting shaft 131 can drive the cam to rotate in the matching groove 171, and drive the baffle 107 to move upward or downward along the height direction.

[0128] Of course, the adjusting shaft 131 can also be arranged as an eccentric shaft, and the outer wall of the adjusting shaft 131 can be matched with the matching groove 171, so that the rotation of the adjusting shaft 131 can drive the baffle 107 to move upward or downward. By arranging the eccentric cam 132 outside the adjusting shaft 131, the overall structure can be simplified and the machining process can be simplified.

[0129] The eccentric cam 132 is provided with a through hole, and the adjusting shaft 131 passes through the through hole. The eccentric cam 132 can move axially relative to the adjusting shaft 131. Specifically, the inner wall of the through hole can be provided with a protrusion, and the outer wall of the adjusting shaft 131 can be provided with a sliding groove in the axial direction. The protrusion can slide along the sliding groove and limit the relative rotation between the eccentric cam 132 and the adjusting shaft 131. Alternatively, the inner wall of the through hole can be provided with a sliding groove, and the outer wall of the adjusting shaft 131 can be provided with a protrusion in the axial direction.

[0130] The adjusting shaft 131 and the bearing seat 112 are also connected with a bearing to support the adjusting shaft 131 from the middle position and ensure the stability of the rotation of the adjusting shaft 131.

[0131] As shown, Figure 8 The outer wall of the adjusting shaft 131 is also provided with a scale disc 134, and the support seat is provided with a pointer corresponding to the scale disc 134. The angle of rotation of the adjusting shaft 131 can be observed by the pointer and the scale disc 134, and the height of the baffle 107 can be obtained according to the angle, which is convenient for observation.

[0132] The adjusting part 103 also includes a hand wheel 133 and a transmission component 135. The hand wheel 133 is in transmission connection with the adjusting shaft 131 through the transmission component 135 and is used to drive the adjusting shaft 131 to rotate. Since the rotation angle of the adjusting shaft 131 is not large, the hand wheel 133 is used to drive the adjusting shaft 131 to rotate, which is more convenient for accurate adjustment of the height of the baffle 107 compared with the scheme of driving the adjusting shaft 131 to rotate by arranging a motor.

[0133] Specifically, the specific structure of the transmission component 135 is not limited, which can be arranged as a worm gear assembly or a bevel gear assembly, which can achieve speed reduction and make the axial direction of the hand wheel 133 parallel to the paper feeding direction, facilitating the rotation of the hand wheel 133 by the operator.

[0134] The upper surface of the workbench is also provided with a driving wheel. Specifically, after the paperboard 01 is placed on the upper surface of the workbench, the driving wheel can drive the paperboard 01 to move along the paper feeding direction. The driving wheel can provide power for the movement of the paperboard 01 along the paper feeding channel 104.

[0135] A vacuum generator is also arranged below the workbench. The upper surface of the workbench is also provided with a vacuum suction port. The vacuum generator is in communication with the vacuum suction port. By providing suction at the vacuum suction port, the paperboard 01 passing through the vacuum suction port can slide along the surface of the workbench to feed the paper, avoiding the paperboard 01 from being warped during the feeding process, and ensuring the stability of the feeding.

[0136] Specifically, the vacuum generator includes a plurality of vacuum generating units. The upper surface of the workbench is uniformly provided with a plurality of groups of vacuum suction ports along the length direction of the sliding rail 111. Specifically, a plurality of vacuum suction ports can form a group. Each group of vacuum suction ports is in communication with a vacuum generating unit, and each vacuum generating unit is respectively provided with a control valve for opening and closing. In actual operation, after the guide plate 102 slides to the appropriate position along the sliding rail 111, the position of the paper feeding channel 104 is determined. At this time, only the vacuum generating unit corresponding to the vacuum suction port located in the paper feeding channel 104 can be opened. That is, the operator can open the corresponding vacuum generating unit through the control valve according to the specific position of the paper feeding channel 104, without the need to open all the vacuum generating units, which can effectively reduce the cost.

[0137] As shown in FIG. 1, Figure 7 The side of the paper feeding beam 101 away from the sliding rail 111, i.e. the rear side of the paper feeding beam 101, is also provided with a sun gear 108 and a paper pressing plate 109 along the length direction. When the paperboard 01 is attached to the surface of the workbench and fed along the paper feeding channel 104, power is provided by the driving wheel on the upper surface of the workbench. When the paperboard 01 enters the cartoning machine, power is provided by the sun gear 108 to enter the subsequent processing mechanism. The paper pressing plate 109 can press the paperboard 01 to prevent the paperboard 01 from being lifted during the subsequent processing process, which has good stability.

[0138] As shown in FIG. 1, Figure 9 The support assembly includes a slotted beam 211 extending in a horizontal direction, a first support seat 212 and a second support seat 213. The first support seat 212 and the second support seat 213 are arranged at both ends of the slotted beam 211 to support the slotted beam 211.

[0139] The slotted knives are slidingly connected to the slotted beam 211. The driving assembly is in transmission connection with the slotted knives to provide driving force for the slotted knives. Adjacent two slotted knives are used to process on both sides of a paperboard 01. The slotted knives can slide along the extension direction of the slotted beam 211 under the driving of the driving assembly to adapt to the size of the paperboard 01 to be processed.

[0140] When there are three grooving blades, the three grooving blades are arranged sequentially along the extension direction of the grooving beam 211. The grooving blade in the middle cooperates with the grooving blades on both sides of it so that two pieces of cardboard 01 can be processed at the same time.

[0141] In a specific embodiment, such as Figure 9 As shown, the grooving mechanism includes four grooving cutters. The grooving cutters are divided into at least a first cutter group 202 and a second cutter group 203, in pairs. The two grooving cutters in the first cutter group 202 are a first grooving cutter 221 and a second grooving cutter 222, and the two grooving cutters in the second cutter group 203 are a third grooving cutter 231 and a fourth grooving cutter 232.

[0142] A guide rail 215 is constructed on the slotted beam 211, extending along the length of the slotted beam 211. The first cutter group 202 and the second cutter group 203 are slidably connected to the guide rail 215. Multiple slotting cutters are arranged sequentially along the guide rail 215.

[0143] Each grooving knife is connected to a slider 282. The grooving knife slides along the guide rail 215 via the slider 282, thereby adjusting the distance between the grooving knives so as to adapt to the size of the cardboard 01.

[0144] In the actual processing, such as Figure 9 As shown, Figure 9 The first processing state of the grooving mechanism is shown. Figure 9 In the process, two adjacent grooving blades are used to process the cardboard 01 on both sides. When two blade sets are provided, the four grooving blades can work in pairs to process two cardboard 01 at the same time, so that the grooving mechanism can process multiple cardboard 01 at the same time.

[0145] Of course, the slotting mechanism can also process only one sheet of cardboard 01. For example... Figure 10 The processing state shown illustrates that when processing a piece of cardboard 01, the two grooving blades of the first blade group 202 are used to process the cardboard 01. Therefore, the grooving mechanism is configured with multiple processing states to meet the needs of a single cardboard 01 processing station.

[0146] In some embodiments, see continue to see Figure 9 and Figure 10 The drive assembly includes a first motor 241 and a second motor 242. The two motors drive a first cutter group 202 and a second cutter group 203, respectively. The output terminal of the first motor 241 is connected to a first lead screw 251, and the output terminal of the second motor 242 is connected to a second lead screw 252. The first motor 241 is connected to the first cutter group 202 via the first lead screw 251, and the second motor 242 is connected to the second cutter group 203 via the second lead screw 252.

[0147] Specifically, as shown in Figure 10 , the first screw rod 251 and the second screw rod 252 are respectively provided with two screw nuts. The first slotting cutter 221 is fixedly connected with one screw nut through the first connecting piece 291. The second slotting cutter 222 is connected with the other screw nut through the second connecting piece 292.

[0148] Similarly, the third slotting cutter 231 is fixedly connected with one screw nut provided on the second screw rod 252 through the third connecting piece 293, and the fourth slotting cutter 232 is fixedly connected with the other screw nut provided on the second screw rod 252 through the fourth connecting piece 294.

[0149] In actual use, the first motor 241 and the second motor 242 can drive the first screw rod 251 and the second screw rod 252 to move linearly to drive the slotting cutters connected with the screw nuts to move synchronously through the rotation of the screw rods.

[0150] In an example, as shown in Figure 10 , the first motor 241 is fixedly arranged on the first support base 212, and the second motor 242 is fixedly arranged on the second support base 213. The first screw rod 251 and the second screw rod 252 are located between the first support base 212 and the second support base 213.

[0151] For details, please refer to Figure 11 , the first support base 212 includes a third bearing seat plate 212b connected with the slotting beam 211 and arranged perpendicularly on the slotting beam 211, and a motor flange 212c parallel to the third bearing seat plate 212b. The first motor 241 is fixed to the side of the motor flange 212c away from the third bearing seat plate 212b, and the first screw rod 251 is arranged on the side of the third bearing seat plate 212b away from the motor flange 212c. The end of the first screw rod 251 penetrates through the third bearing seat plate 212b and is connected with the output end of the first motor 241.

[0152] Similarly, the second motor 242 is fixed to the second support base 213 in the same way. Therefore, by fixing the first motor 241 and the second motor 242 to the first support base 212 and the second support base 213 respectively, the problem of occupying more space in the height direction of the driving assembly caused by fixing the two motors on the same side can be avoided.

[0153] Optionally, continuing to refer to Figure 10 , the first screw rod 251, the second screw rod 252 and the guide rail 215 are parallel, and are sequentially arranged in the vertical direction with the first screw rod 251 closer to the guide rail 215. Therefore, the size of the slotting mechanism in the width direction can be reduced.

[0154] In one specific embodiment, as shown in Figure 9 and Figure 10 , the two slotting knives of the first knife set 202 are located between the two slotting knives of the second knife set 203. That is, the first slotting knife 221 and the second slotting knife 222 are located between the third slotting knife 231 and the fourth slotting knife 232. Among them, the first slotting knife 221 is closer to the third slotting knife 231, and the second slotting knife 222 is closer to the fourth slotting knife 232.

[0155] The two slotting knives of the first knife set 202 are arranged symmetrically about the center, and the two slotting knives of the second knife set 203 are arranged symmetrically about the center. The symmetric center of the first knife set 202 coincides with the symmetric center of the second knife set 203. Thus, the feeding direction of the slotting mechanism is located at the center.

[0156] Of course, the two slotting knives of the first knife set 202 and the second knife set 203 can also be arranged in a staggered manner. That is, the first slotting knife 221 is arranged between the third slotting knife 231 and the fourth slotting knife 232, and the second slotting knife 222 is arranged on the side of the fourth slotting knife 232 away from the first slotting knife 221. However, with such an arrangement, the feeding position of the paperboard 01 will be offset, resulting in a more complex control logic of the slotting mechanism.

[0157] In one specific embodiment, the first slotting knife 221 and the second slotting knife 222 can be synchronously moved towards the direction close to or away from the symmetric center, and the third slotting knife 231 and the fourth slotting knife 232 can also be synchronously moved towards the direction close to or away from the symmetric center.

[0158] Specifically, as shown in Figure 9 , Figure 10 and Figure 12 , the first lead screw 251 and the second lead screw 252 each include a first rod portion and a second rod portion. The first rod portion is used to be in driving connection with one slotting knife, and the second rod portion is used to be in driving connection with another slotting knife. The first rod portion and the second rod portion are coaxially arranged, and the helical directions of the first rod portion and the second rod portion are opposite, that is, the outer surfaces of the first rod portion and the second rod portion are each configured with a helical structure, and the extension directions of the helical structures of the first rod portion and the second rod portion are opposite.

[0159] As shown in Figure 12As shown, taking the first screw rod 251 as an example, one of the first rod part 251a or the second rod part 251b of the first screw rod 251 is connected with the output end of the corresponding first motor 241. The first rod part 251a and the second rod part 251b are connected through the shaft coupling 283. The first rod part 251a and the second rod part 251b rotate synchronously under the action of the shaft coupling 283, and since the screw directions of the first rod part 251a and the second rod part 251b are opposite, the first slotting cutter 221 connected with the first rod part 251a and the second slotting cutter 222 connected with the second rod part 251b can move synchronously in the direction of approaching or moving away from each other.

[0160] Similarly, the third slotting cutter 231 and the fourth slotting cutter 232 are connected with the first rod part 252a and the second rod part 252b of the second screw rod 252 respectively, and the first rod part 252a and the second rod part 252b are connected through the shaft coupling 283 and rotate reversely to enable the third slotting cutter 231 and the fourth slotting cutter 232 to move in the direction of approaching or moving away from each other.

[0161] In the actual processing process, as shown in a first processing state, Figure 9 the distance between the first slotting cutter 221 and the third slotting cutter 231 is adjusted respectively, so that the first slotting cutter 221 and the third slotting cutter 231 jointly process a paperboard 01. At the same time, the distance between the second slotting cutter 222 and the fourth slotting cutter 232 is adjusted, so that the second slotting cutter 222 and the fourth slotting cutter 232 can also process a paperboard 01. Or, as shown in a processing state, Figure 10 the distance between the first slotting cutter 221 and the second slotting cutter 222 is adjusted to process a paperboard 01. In the present application, the number of slotting cutters is not specifically limited, and more slotting cutters can be provided to process more paperboards 01 at the same time.

[0162] Of course, the first screw rod 251 and the second screw rod 252 can also be an integral structure, so that the first slotting cutter 221 and the second slotting cutter 222 can move in the same direction, and the third slotting cutter 231 and the fourth slotting cutter 232 can move in the same direction. However, when the first screw rod 251 and the second screw rod 252 are an integral structure, the adjustable range of the distance between the four slotting cutters is narrow.

[0163] Further, as shown, Figure 12 in order to increase the connection strength of the first rod part and the second rod part, a third support seat 214 is arranged on the slotting beam 211. The third support seat 214 includes a first bearing seat plate 214a and a second bearing seat plate 214b arranged in parallel, and the shaft coupling 283 is arranged between the first bearing seat plate 214a and the second bearing seat plate 214b.

[0164] The first rod part and the second rod part are arranged on both sides of the third support base 214, and the ends of the first rod part and the second rod part connected with each other pass through the corresponding first bearing seat plate 214a and the second bearing seat plate 214b respectively to be connected with the two ends of the shaft coupling 83.

[0165] In some embodiments, referring to Figures 13-15 , the slotting knives can be sequentially spliced in pairs in the extension direction of the cross beam.

[0166] In a specific embodiment, as shown in Figure 13 , the first slotting knife 221 and the third slotting knife 231 can be sequentially spliced, and the second slotting knife 222 and the fourth slotting knife 232 can be sequentially spliced, so that the size of the slotting on the paperboard 01 can be increased.

[0167] Optionally, as shown in Figure 14 , the slotting knife comprises a knife body 261 and a knife edge part 262, one of the two spliced slotting knives is configured with a avoiding part 263 arranged on the knife body 261. The end of the other slotting knife extends into the avoiding part 263.

[0168] Continuing to refer to Figure 14 , taking the second slotting knife 222 and the fourth slotting knife 232 as an example, the end surface of the second slotting knife 222 and the fourth slotting knife 232 spliced with each other is recessed in the direction away from the fourth slotting knife 232 to form the avoiding part 263, so that the end of the fourth slotting knife 232 can extend into the avoiding part 263.

[0169] Optionally, the knife body 261 is in a slope shape, that is, the size of one end of the knife body 261 in the vertical direction is greater than the size of the other end of the knife body 261 in the vertical direction. The avoiding part 263 is arranged at the larger end of the second slotting knife 222, and the smaller end of the fourth slotting knife 232 extends into the avoiding part 263, so that the structure Figure 15 , Figure 15 is Figure 14 a bottom view. As can be seen from Figure 15 , the projection range of the spliced slotting knives in the horizontal plane is a continuous rectangle. The continuous rectangle means that the projection range of the knife edge 262 of the spliced slotting knives continuously extends without interruption. In this way, the length of the slotting on the paperboard 01 can be increased, and a continuous and uninterrupted slot can also be formed on the paperboard 01.

[0170] Of course, the avoiding part 263 can not be arranged, and the end surfaces of the fourth slotting knife 232 and the second slotting knife 222 spliced with each other abut. In this way, the processing mode of the slotting knife is relatively simple, but when the slotting on the paperboard 01 is processed in this splicing mode, burrs are easily formed.

[0171] In some embodiments of the present application, the slotting mechanism further comprises a sensing assembly for sensing the position of each slotting knife.

[0172] The sensing assembly comprises a first sensing part and a second sensing part, and a sensor detection piece capable of forming an inductive cooperation with the first sensing part and the second sensing part respectively. The first sensing part is used to monitor the position of at least one slotting knife of the first knife group 202, and the second sensing part is used to monitor the position of at least one slotting knife of the second knife group 203. The first sensing part is closer to the third support seat 214, and the second sensing part is closer to the first support seat 212 or closer to the second support seat 213.

[0173] Specifically, referring to Figure 16 For example, the fourth slotting knife 232 is taken as an example for description. The slider 282 connected with the fourth slotting knife 232 is provided with a sensor detection piece 271. The sensor detection piece 271 is used to form an induction with the second sensing part.

[0174] In actual use, after the slotting mechanism is started, the second sensing part detects the position of the fourth slotting knife 232. Since the third slotting knife 231 and the fourth slotting knife 232 are symmetrically arranged at the center and move synchronously, the position of the third slotting knife 231 can be determined through the position of the fourth slotting knife 232, and the position initialization of the slotting knife after the slotting mechanism is started is completed, thereby facilitating subsequent operations.

[0175] Among them, the sensing assembly is, for example, a proximity sensor, etc., which can detect the position of the slotting knife.

[0176] Please refer to Figure 17 、 Figure 18 、 Figure 19 In a specific embodiment, the line pressing wheel mechanism provided by the present application is provided with two parallel cross beams, i.e., a first cross beam 311 and a second cross beam 312. Eight line pressing wheel units 320 are spaced apart and installed in the transverse direction on the first cross beam 311. Each line pressing wheel unit 320 is integrated with a front rolling unit 330 and a longitudinal cutter unit 440. Each longitudinal cutter unit 440 is installed on the second cross beam 312. In this way, on the first cross beam 311 and the second cross beam 312, there are a total of eight line pressing wheel units 320, front rolling units 330 and longitudinal cutter units 440.

[0177] Specifically, each line pressing wheel unit 320 is provided with a transverse driving component 321 for driving the line pressing wheel unit 320 to move transversely along a first guide rail 323, and a first longitudinal driving component 322 for driving the line pressing wheel 324 to move up and down, and each line pressing wheel unit 320 is provided with a first intermediate carrier 325, the left and right sides of the first intermediate carrier 325 are respectively formed with a left mounting position and a right mounting position, and the line pressing wheel 324 of the line pressing wheel unit 320 can be selectively mounted in the left mounting position or the right mounting position.

[0179] In the embodiment, the front roller of the front rolling unit 330 is a pre-pressing wheel 332, which is used to pre-press the paperboard before pressing the line, and after the paperboard is pressed by the pre-pressing wheel 332, the line pressing wheel 324 is used to press the required longitudinal line.

[0180] Each front rolling unit 330 is provided with a second longitudinal driving component 333 for driving the pre-pressing wheel 332 to move up and down, and each front rolling unit 330 is provided with a second intermediate carrier 334, the left and right sides of the second intermediate carrier 334 are respectively formed with a left mounting position and a right mounting position, and the pre-pressing wheel 332 can be selectively mounted in the left mounting position or the right mounting position.

[0181] More specifically, the transverse driving component 321 mainly consists of a gear 3211, a rack 3212 and a motor 3213, the rack 3212 is installed on the rear side of the first cross beam 311 in the transverse direction, and the motor 3213 is installed on the bracket and is in meshing transmission with the rack 3212 through the gear 3211. When the motor 3213 operates, the line pressing wheel unit 320 and the front rolling unit 330 can be driven to move left and right on the first cross beam 311 through the meshing relationship between the gear 3211 and the rack 3212, so as to adjust the position.

[0182] The front rolling unit 330 and the corresponding line pressing wheel unit 320 are installed on the first cross beam 311 through the same bracket, the second guide rail 331 of the front rolling unit 330 is located on the front side of the first cross beam 311, and the first guide rail 323 of the line pressing wheel unit 320 is located on the rear side of the first cross beam 311.

[0183] The first longitudinal driving component 322 is a first air cylinder, and the second longitudinal driving component 333 is a second air cylinder, and the first air cylinder and the second air cylinder are arranged longitudinally, and the downwardly extending piston rods of the first air cylinder and the second air cylinder are connected with the first intermediate carrier 325 and the second intermediate carrier 334 respectively.

[0184] The longitudinal section of the first intermediate carrier 325 and the second intermediate carrier 334 is T-shaped, respectively having a transverse connecting plate and a vertical mounting plate, the vertical mounting plate being located at the middle position below the transverse connecting plate, and the left and right sides of the vertical mounting plate respectively forming a left mounting position and a right mounting position.

[0185] Eight longitudinal cutting knife units 440 are installed on the second cross beam 312 through the third guide rail 441, each longitudinal cutting knife unit 440 is respectively corresponding to and connected with the eight creasing wheel units 320, and can move transversely along the third guide rail 441 following the creasing wheel units 320; each longitudinal cutting knife unit 440 is respectively provided with a third intermediate carrier 442, the left and right sides of the third intermediate carrier 442 respectively form a left mounting position and a right mounting position, and the blade 443 of the longitudinal cutting knife unit 440 can be selectively mounted on the left mounting position or the right mounting position.

[0186] In addition, each longitudinal cutting knife unit 440 is respectively provided with a fourth intermediate carrier 444, the left and right sides of the fourth intermediate carrier 444 respectively form a left mounting position and a right mounting position, and the knife sharpening unit 445 of the longitudinal cutting knife unit 440 can be selectively mounted on the left mounting position or the right mounting position.

[0187] Since there are a total of eight groups of creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 340, various working modes can be formed by selection and combination. Some typical working modes are listed as follows:

[0188] For example, in the first mode, the carton machine feeds paper from the middle passage, and the four groups of creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 340 located in the middle are in working state, and the remaining creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 340 do not participate in processing and can be in the avoiding position.

[0189] In the second mode, the carton machine feeds paper from the left passage, and the four groups of creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 440 located on the left side are in working state, and the remaining creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 440 do not participate in processing and can be in the avoiding position.

[0190] In the third mode, the carton machine feeds paper from the right passage, and the four groups of creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 440 located on the right side are in working state, and the remaining creasing wheel units 320, front rolling units 330 and longitudinal cutting knife units 440 do not participate in processing and can be in the avoiding position.

[0191] In the fourth mode, the carton machine simultaneously feeds paper from the left channel and the right channel, and the four groups of creasing wheel units 320, the front rolling unit 330 and the slitting knife unit 440 on the left side and the four groups of creasing wheel units 320, the front rolling unit 330 and the slitting knife unit 440 on the right side are simultaneously in working condition. In this mode, one carton machine can simultaneously process two cartons, and the specifications of the two cartons can be the same or different.

[0192] It can be understood that in other embodiments, the four groups of creasing wheel units 320, the front rolling unit 330 and the slitting knife unit 440 on the left side or the right side are not necessarily in working condition, and it is possible that the two outermost groups work together, for example, for a particularly wide size, or the nearest group works when moving in the transverse direction, and the like. Due to the strong editability, there are many working modes that can be formed in actual use, which will not be illustrated one by one here.

[0193] The creasing wheel 324, the pre-creaser 332, the blade 443 and the knife grinding unit 445 in the same group are generally simultaneously installed on the left mounting position or the right mounting position, that is, when the creasing wheel 324 is replaced from the left mounting position to the right mounting position, the pre-creaser 332, the blade 443 and the knife grinding unit 445 are also replaced from the left mounting position to the right mounting position.

[0194] Please refer to Figure 21 , Figure 22 In actual use, the front roller of the front rolling unit 330 can be replaced with different rollers according to the use requirements, so as to realize different functions.

[0195] For example, the pre-creaser 332 is replaced with the offset creasing wheel 335, and the creasing protrusion 3351 of the offset creasing wheel 335 is in an offset position and is transversely offset from the creasing protrusion 3241 of the corresponding creasing wheel 324.

[0196] The longitudinal creasing lines processed by the creasing wheel 324 and the offset creasing wheel 335 are not located on the same straight line, the creasing wheel 324 is used to process the creasing line with a low position, and the offset creasing wheel 335 is used to process the creasing line with a high position, so as to form high-low creasing lines.

[0197] This creasing method fully considers the influence of the thickness of the paperboard on folding. After improvement, because the different segments of the longitudinal creasing lines are offset by a certain distance, when the four flaps at the top and bottom of the carton are folded inward, the flaps at the top can be strictly folded according to the offset longitudinal creasing lines. In this way, deformation at the root is avoided, which is beneficial to folding operation and can ensure the tightness and appearance of the carton.

[0198] In other embodiments, the front rollers of the front rolling unit 330 can be replaced by paper pressing wheels 336. If the front rollers are replaced by the paper pressing wheels 336, the minimum paper feeding length can be effectively shortened, so as to better adapt to the processing requirements of some box types.

[0199] Please continue to refer to Figure 23 , each slitting knife unit 440 is provided with a fixed arm 446, a cantilever arm and a cylinder 447, wherein the cantilever arm constitutes a third intermediate carrier 442, the blade 443 is mounted on the fixed arm 446 through the cantilever arm, and the cylinder 447 is used to drive the cantilever arm to swing relative to the fixed arm 446, so as to drive the blade 443 to move up and down, so as to approach or move away from the paperboard.

[0200] The hinge position of the fixed arm 446 and the cantilever arm is provided with a transverse driving shaft 448. In this embodiment, the driving shaft 448 is a hexagonal shaft. The hexagonal shaft transmits power to the blade 443 through a transmission component (such as a gear train, not shown in the figure) to drive the blade to rotate and perform the paper cutting action.

[0201] Since the line pressing wheel 324, the pre-pressing wheel 332, the blade 443 and the knife grinding unit 445 can be selectively mounted on the left mounting position or the right mounting position, the left and right positions of the line pressing wheel can be replaced according to the width of the minimum size to be processed, as shown in Figure 20 The dashed line shows the state of the line pressing wheel 324 in the left mounting position, and the solid line shows the state of the line pressing wheel 324 in the right mounting position.

[0202] When processing ultra-thin cartons, the two line pressing wheel units 320 for pressing longitudinal score lines can be mounted in the right mounting position and the left mounting position respectively, so that the distance between the two line pressing wheels 324 is further reduced, and a longitudinal score line with a narrower distance can be pressed, so as to process a thinner carton. When processing a carton of a conventional size, the line pressing wheels 324 can be mounted in the right mounting position or the left mounting position. When processing a carton of an ultra-high size, the line pressing wheels 324 can be mounted in the left mounting position and the right mounting position respectively, so that the distance between the two line pressing wheels 324 is further increased, and a longitudinal score line with a wider distance can be pressed, so as to process a carton of a higher size.

[0203] That is, because of the design of the left mounting position and the right mounting position, the position of the line pressing wheel 324 can be flexibly adjusted according to actual needs during use, so as to produce more types and specifications of cartons.

[0204] As shown in Figures 24-28 , the cross-cut knife mechanism 500 in this embodiment includes a blade 56, which can be, for example Figure 27 , 28The disc-shaped structure shown can be modified, but the blade 56, as the cutting actuator, can also be other shapes, as long as it can cut the cardboard. The cross-cutting mechanism 500 also includes a first drive unit 53 for driving the blade 56 to move laterally, and a second drive unit 55 for driving the blade 56 to move up and down. The first drive unit 53... Figure 25 It includes a motor, and the second drive unit 55 in this embodiment is as follows: Figure 27 , 28 As shown, the first drive cylinder can include a pneumatic cylinder, or other drive structures such as a hydraulic cylinder. The first drive cylinder can provide driving force quickly and reliably.

[0205] In addition, the cross-cutting mechanism 500 also includes a transmission assembly 54, such as... Figure 27 As shown, the transmission assembly 54 includes a driving gear 542, a driven gear 544, a swing unit 543, and a rack 545 extending laterally. The driven gear 544 is connected to the blade 56. In this embodiment, the blade 56 has a disc-shaped structure. The driven gear 544 and the blade 56 can be fixed coaxially at this time, and the two rotate synchronously.

[0206] Can continue to combine Figures 29-31 In this embodiment, the swing unit 543 of the transmission assembly 54 includes a first swing arm 5432, a second swing arm 5434, and a first transmission gear 5431 and a second transmission gear 5433 that mesh with each other. Thus, the transmission assembly 54 actually includes four gears: a driving gear 542, a first transmission gear 5431, a second transmission gear 5433, and a driven gear 544, arranged sequentially from top to bottom. The first transmission gear 5431 also meshes with the driving gear 542, meaning the first transmission gear 5431 meshes with both the driving gear 542 and the second transmission gear 5433. Conversely, the second transmission gear 5433 also meshes with the driven gear 544, meaning the second transmission gear 5433 meshes with both the driven gear 544 and the first transmission gear 5431. In other words, in this embodiment, the driving gear 542 and the driven gear 544 do not mesh directly, but are indirectly connected through the first transmission gear 5431 and the second transmission gear 5433, enabling the driving gear 542 to drive the driven gear 544.

[0207] In addition, the first swing arm 5432 and the second swing arm 5434 of the swing unit 543 each has two ends, and the two ends of the two are defined as the first end and the second end in the embodiment, wherein the first end of the first swing arm 5432 is hinged with the first transmission gear 5431, and the hinging axis is coaxial with the first transmission gear 5431; the second end of the first swing arm 5432 is hinged with the first end of the second swing arm 5434, and the hinging axis is coaxial with the second transmission gear 5433; and the second end of the second swing arm 5434 is hinged with the driven gear 544, and the hinging axis is coaxial with the driven gear 544. The coaxial mentioned herein refers to the coaxial with the rotation axis of the corresponding gear, so that the swing of the swing arm and the rotation of the gear do not interfere.

[0208] In combination Figure 30 It is understood that when the second driving part 55 pulls the blade 56 to lift, the driven gear 544 lifts synchronously with the blade 56, and the driven gear 544 and the blade 56 are equivalent to be suspended on the second driving part 55, when the driven gear 544 and the blade 56 lift, the first swing arm 5432 and the second swing arm 5434 act as a connecting rod mechanism and will swing accordingly, and the second transmission gear 5433 is connected with the two swing arms, so that the position of the second transmission gear 5433 changes, but due to the connection mode of the second transmission gear 5433 with the two swing arms, the position change of the second transmission gear 5433 does not affect the engagement of the second transmission gear 5433 with the first transmission gear 5431 and the driven gear 544. Figure 30 From the perspective, when the blade 56 moves up, the included angle between the first swing arm 5432 and the second swing arm 5434 decreases, and the second transmission gear 5433 moves left and up, when the blade 56 moves down, the included angle between the first swing arm 5432 and the second swing arm 5434 increases, and the second transmission gear 5433 moves right and down, but it always keeps engagement with the first transmission gear 5431 and the driven gear 544, when the blade 56 moves down to the cutting height, the power of the first driving part 53 can be transmitted to the blade 56 through the transmission assembly 54 to perform cutting operation.

[0209] Again looking at Figure 26The transmission assembly 54 in the embodiment further comprises a transversely extending rack 545, the driving gear 542 can engage with the rack 545, the rack 545 is kept stationary relative to the carton machine, when the driving gear 542 moves transversely relative to the rack 545, the driving gear 542 is also engaged with the rack 545 and rotates relative to the rack 545, so that the driving gear 542 drives the first transmission gear 5431 to rotate, the first transmission gear 5431 drives the second transmission gear 5433 to rotate, the second transmission gear 5433 drives the driven gear 544 to rotate, and the driven gear 544 drives the blade 56 to rotate, that is, the driving gear 542 can finally drive the driven gear 544 to rotate and move transversely, and correspondingly drive the blade 56 to rotate and move transversely, the blade 56 moves transversely, that is, the blade 56 can perform trimming operation on the paperboard along the transverse direction, and the synchronous rotation of the blade 56 during transverse movement facilitates smooth cutting.

[0210] Therefore, the transverse cutter mechanism 500 in the embodiment sets the second driving part 55 to drive the blade 56 to lift and lower, when cutting the paperboard along the transverse direction, at a position where cutting is not needed, the second driving part 55 can be controlled to lift the blade 56 to move away from the paperboard, and at a position where cutting is needed, the second driving part 55 can be controlled to lower the blade 56 to perform cutting operation, so that the transverse cutter mechanism 500 can perform whole trimming operation along the transverse direction of the paperboard, or can perform partial trimming according to needs, such as cutting only a notch, thereby improving the flexibility of transverse trimming and adapting to the production needs of multiple types of cartons.

[0211] In addition, the transmission assembly 54 of the transverse cutter mechanism 500 in the above embodiment is provided with the swing unit 543, which can not affect the transmission of the driving gear 542 and the driven gear 544 in the transmission assembly 54 when the blade 56 is lifted and lowered, and the driven gear 544 still remains in transmission connection after being lifted or lowered with the blade 56, which is simple in structure and stable and reliable.

[0212] However, it can be understood that the transmission assembly 54 is not limited to comprising the swing unit 543, for example, the second driving part 55 can drive the whole transmission assembly 54 to lift and lower, and then drive the blade 56 to lift and lower, but compared with the above-mentioned manner of setting the swing unit 543, the swing unit 543 allows the driven gear 544 in the transmission assembly 54 to lift and lower, while other transmission components in the transmission assembly 54 do not need to be lifted and lowered, the whole structure is more stable, the force required for the second driving part 55 to lift and lower is smaller, and the structure is more compact.

[0213] Please continue to combine Figure 32 , 33It is understood that the cross-cutting knife mechanism 500 in the embodiment also includes a base plate 514, the driving gear 542 is mounted on the base plate 514, and the first transmission gear 5431 of the swing unit 543 can also be mounted on the base plate 514, that is, the relative positions of the driving gear 542 and the first transmission gear 5431 are unchanged, and the two only mesh with each other and rotate relative to each other to drive. The second driving part 55 is specifically a first driving cylinder, which includes a piston rod and a cylinder body, one of which is connected with the blade 56, and the other is connected with the base plate 514. In this way, the first driving cylinder can drive the blade 56 and the driven gear 544 to rise and fall relative to the base plate 514. In the embodiment, the piston rod of the first driving cylinder is connected with the blade 56, and the cylinder body and the base plate 514 are fixed. It can be seen that the driving gear 542 and the first transmission gear 5431 can also be mounted on the cylinder body of the second driving part 55.

[0214] As shown in Figure 33 , the first driving part 55 is mounted on the base plate 514, and the first driving part 55 is mounted on one side of the base plate 514 in the longitudinal direction, and the driving gear 542 and the first transmission gear 5431 are located on the other side of the base plate 514 in the longitudinal direction, which facilitates installation and compact structure.

[0215] In more detail, the cross-cutting knife mechanism 500 also includes a base 513, and the driven gear 544 and the blade 56 are both mounted on the base 513. The base 513 is connected with the base plate 514 through the second driving part 55, that is, the second driving part 55 drives the base 513 to rise and fall, thereby driving the blade 56 and the driven gear 544 to rise and fall. The base 513 can provide a mounting position for the driven gear 544 and the blade 56, so that they can be reliably mounted and connected.

[0216] Please continue to refer to Figure 24 , 32 , combined with Figure 33It is understood that in the embodiment, the cross-cutting knife mechanism 500 further comprises a cross-cutting beam 51 serving as a main frame of the cross-cutting knife mechanism 500, and the cross-cutting beam 51 is provided with a slide rail 515 extending in the transverse direction, which can be arranged at the bottom of the cross-cutting beam 51, and the base plate 514 is in sliding fit with the slide rail 515. For example, the base plate 514 can be provided with a sliding block 5141 in sliding fit with the slide rail 515, which can be separately mounted to the base plate 514 or integrally formed with the base plate 514, and the embodiment is not limited in particular. As described above, when the first driving part 53 drives the driving gear 542 to rotate, it is in mesh with the rack 545, so that the driving gear 542 will be synchronously moved in the transverse direction along the rack 545, and the base plate 514 and the cross-cutting beam 51 are in sliding fit, so that the driving gear 542 will drive the base plate 514 to move along the cross-cutting beam 51 when it moves in the transverse direction. In this way, the base plate 514 provides reliable support and guidance for the driving gear 542 and does not affect its transverse movement, and the sliding fit between the base plate 514 and the cross-cutting beam 51 can also improve the stability of the transverse movement of the driving gear 542 along the rack 545.

[0217] Further, the cross-cutting knife mechanism 500 can further comprise a transmission assembly 54, and the first driving part 53 is in driving connection with the transmission assembly 54. Figures 24-28 The first driving part 53 in the embodiment comprises a motor, and the transmission assembly 54 further comprises a belt 541, which can be driven by the motor to rotate. The motor can drive the belt 541 to rotate through the shaft coupling 512, and the belt 541 can in turn drive the driving gear 542 to move along the rack 545. The plane where the annular formed by the belt 541 is located is the plane where the transverse and longitudinal directions are located. The driving gear 542 is driven to move in the transverse direction by the belt 541, and the driving is stable. It can be known that the first driving part 53 is not limited to driving the driving gear 542 to rotate through the belt 541. For example, the motor can directly drive the driving gear 542 to rotate, which can be synchronously moved in the transverse direction relative to the rack 545, but the motor also needs to be synchronously moved in the transverse direction. Here, the belt 541 is arranged for transmission, and the motor can be in a relatively stable position, and the transmission is more reliable and stable.

[0218] As shown in Figure 28 The belt 541 of the transmission assembly 54 in the embodiment is provided with a clamping plate 511 fixed with the belt 541, for example, clamped with the belt 541 to achieve fixation, or fixed with the belt 541 through fasteners, etc. When the belt 541 rotates, it can drive the clamping plate 511 and the driving gear 542 to drive the driving gear 542 to move along the rack 545.

[0219] As shown in Figure 34As shown, the embodiment also provides a pulley mounting seat 57, and the transmission assembly 54 includes two synchronous pulleys 58 for rotating the belt 541, one synchronous pulley 58 is located on one side of the transverse direction of the transverse beam 51, and the other synchronous pulley 58 is located on the other side of the transverse direction of the transverse beam 51, the pulley mounting seat 57 is used to mount the synchronous pulley 58, and the pulley mounting seat 57 can be fixed with the transverse beam 51, or the pulley mounting seat 57 can be fixed with the entire base frame of the carton machine. The length of one side of the belt 541 is substantially the same as the length of the transverse beam 51, or the length of one side of the belt 541 can be greater than the length of the transverse beam 51 to provide a stroke for the driving gear 542 to move in the transverse direction. Similarly, the length of the rack 545 can be equal to or greater than the length of the transverse beam 51 to meet the stroke requirement of the driving gear 542.

[0220] In addition, as Figure 26 shown, the transverse cutting knife mechanism 500 in the embodiment also includes a carton tongue pressing unit 59, which is located on one side of the transverse direction of the blade 56. The carton tongue pressing unit 59 includes a carton tongue pressing plate 591 and a second driving cylinder 593 for driving the carton tongue pressing plate 591 to rise and fall. The carton tongue pressing unit 59 can also include a carton tongue pressing plate mounting seat 592, and the carton tongue pressing plate 591 is specifically mounted on the carton tongue pressing plate mounting seat 592. The second driving cylinder 593 drives the carton tongue pressing plate mounting seat 592, and then drives the carton tongue pressing plate 591 to rise and fall. The carton tongue pressing unit 59 can also be mounted on the base plate 514. For example, the second driving cylinder 593 can be mounted on the base plate 514, Figure 33 In the embodiment, the second driving cylinder 593 and the cylinder body of the first driving part 55 can be integrally arranged. The second driving cylinder 593 can be a pneumatic cylinder or a hydraulic cylinder, etc. When the carton tongue pressing plate 591 is lowered, the corresponding position of the paperboard can be pressed to be thin, so as to facilitate subsequent folding, splicing and other operations. The lower limit position of the carton tongue pressing plate 591 can be lower than the lower limit position of the blade 56, so that the blade 56 can avoid cutting when the carton tongue pressing plate 591 is pressed to be thin.

[0221] As Figure 26 shown, the transverse cutting knife mechanism 500 in the embodiment also includes a glue applying unit 510, which is located on the other side of the transverse direction of the blade 56. The glue applying unit 510 includes a glue applying nozzle 5101, which can apply glue to the corresponding position on the paperboard, so that the part of the processed paperboard can be subjected to bonding operation. The glue applying unit 510 can also be fixed on the base plate 514, as Figure 33 shown, the glue applying unit 510 is provided with a connecting plate 5102, which can be fixed on the side wall of the transverse direction of the base plate 514, or the glue applying unit 510 can be directly connected with the transverse beam 51.

[0222] As Figure 27As shown, the cross-cutting knife mechanism 500 further comprises a paper outlet unit 52, which comprises a plurality of rollers distributed along the transverse direction, and the plurality of rollers can be divided into a plurality of roller groups 521 distributed along the transverse direction, which can be evenly distributed along the transverse direction, and each roller group 521 comprises at least two rollers, which can be pressed on the paperboard and in contact with the paperboard, and when the plurality of roller groups 521 are rolled, the paperboard can be moved out of the cross-cutting knife mechanism 500 along the longitudinal direction so as to move to the next process, such as a carton machine which can further comprise a punching die group to continue the punching operation, or the paper outlet unit 52 can also directly move the paperboard out of the carton machine. Specifically, the paper outlet unit 52 can be arranged on the cross-cutting beam 51, which serves as the framework of the cross-cutting knife mechanism 500, facilitating the installation of the plurality of roller groups 521 and the arrangement of the roller groups 521 along the transverse direction, so as to relatively uniformly push the paperboard out of the cross-cutting knife mechanism 500.

[0223] The paper outlet unit 52 can further comprise a third driving cylinder 522, which can be installed on the cross-cutting beam 51, as shown.
