[0036] In order to make the technical solutions and advantages of the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0037] Embodiment One

[0038] The carton processing machine of the embodiments of the present application can be applied to continuous folding paperboard and ordinary paperboard, and is more used in the case of continuous folding paperboard. As shown in Figure 1A The carton processing machine includes a paperboard stock bin 1, a paper changer 2 and a carton maker 3, and the paper changer 2 and the carton maker 3 are arranged at intervals.

[0039] As shown in Figure 3A The paper changer 2 is used to clamp paperboards 41 of multiple widths in vertical layers and also used to drive the paperboards 41 to move up and down in the vertical direction, and after the selected paperboard moves to a preset height, the selected paperboard is driven to enter the carton maker 3; the carton maker 3 is used to process the paperboard to form a carton, and the processing includes cutting, transverse slotting, transverse creasing, longitudinal creasing and longitudinal slitting.

[0040] The paper changer holds the paperboards of different widths in a layered manner in the vertical direction, and can drive all the paperboards to move up and down in the vertical direction so that the selected paperboard moves to a preset height. In this way, the paperboard with the highest utilization rate can be selected from the paperboards of different widths according to the size of the carton, i.e., as the selected paperboard, so that the selected paperboard has a smaller cut part and less paperboard waste. Then, the paper changer drives the selected paperboard into the carton making machine; the carton making machine cuts, transversely slots, transversely lines, longitudinally lines and longitudinally cuts the paperboard to form the carton.

[0041] The selected paperboard enters the carton making machine from the front end of the carton making machine, is fed from front to back in the carton making machine, and is processed by transverse cutting, transverse slotting and lining, longitudinal cutting and lining to form the carton. The carton is fed to be discharged, and the carton 42 is obtained. As shown in Figure 1B and Figure 1C , the transverse cutting line 425, the transverse slot 421, the transverse line 422, the longitudinal line 424 and the longitudinal cutting line 423 are shown. As shown in Figure 2A 、 Figure 2B 、 Figure 2C and Figure 2D , the carton making machine 3 includes a longitudinal cutting and lining module 30 for longitudinal cutting and lining, and the longitudinal cutting and lining module 30 includes a longitudinal cutter 31 which is a cutter integrated with longitudinal cutting and lining.

[0042] The structure of the carton making machine will be described below.

[0043] In the implementation, as shown in Figure 2A 、 Figure 2B and Figure 2C , the carton making machine includes:

[0044] The carton making machine frame 32 has a front part and a rear part, which are the paper feeding side and the paper discharging side in sequence;

[0045] The first paper feeding module 321 is arranged on the paper feeding side;

[0046] The second paper feeding module 322 and the second transverse cutting module 332 are arranged on the paper discharging side in front and back, respectively, and the second transverse cutting module 332 can move up and down and move in the transverse direction to cut transversely; the transverse direction is perpendicular to the front and back direction and the vertical direction;

[0047] The carton processing machine further includes a control unit, which processes the paperboard between the first paper feeding module and the second paper feeding module:

[0048] In the case that the preset length of the processed carton is less than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, when the actual length of the processed carton passing through the second transverse cutting module 332 has reached the preset length of the processed carton, the first paper feeding module 321 and the second paper feeding module 322 are controlled to stop feeding paper, the second transverse cutting module 332 is controlled to move downward and cut the paperboard in the transverse direction to form a transverse cutting line 425.

[0049] In the case that the preset length of the processed carton is less than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the front end of the paperboard is first conveyed by the first paper feeding module 321, when the actual length of the paperboard passing through the second transverse cutting module 332 has reached the preset length of the processed carton and has reached the second paper feeding module 322, the first paper feeding module 321 and the second paper feeding module 322 are controlled to stop feeding paper, the second transverse cutting module 332 is controlled to move downward and cut the paperboard in the transverse direction, at this time, the length of the cut paperboard is the preset length of the processed carton. That is, in the case that the preset length of the processed carton is less than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the second transverse cutting module 332 is controlled to cut in the transverse direction at the appropriate time.

[0050] In the implementation, as shown in Figure 2A 、 Figure 2B and Figure 2C , the carton making machine further comprises:

[0051] a first transverse cutting module 331, the first paper feeding module 321 and the first transverse cutting module 331 are arranged in front of and behind the paper feeding side, the first transverse cutting module 331 can move up and down and can move in the transverse direction to cut in the transverse direction;

[0052] In the case that the preset length of the processed carton is greater than the distance between the first paper feeding module 321 and the second paper feeding module 322, when the actual length of the processed carton passing through the first transverse cutting module 331 has reached the preset length of the processed carton and the processed carton has reached the second paper feeding module 322, the first paper feeding module 321 and the second paper feeding module 322 are controlled to stop feeding paper, the first transverse cutting module 331 is controlled to move downward and move in the transverse direction to cut the paperboard in the transverse direction.

[0053] In the case that the preset length of the paper box to be processed is greater than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the front end of the paperboard is first conveyed by the first paper feeding module 321, and when the actual length of the first transverse cutting module 331 has reached the preset length of the processed paperboard and the paperboard has reached the second paper feeding module 322, the first paper feeding module 321 and the second paper feeding module 322 stop feeding paper, the first transverse cutting module 331 is controlled to move downward and cut the paperboard in the transverse direction, and at this time, the length of the cut paperboard is the preset length of the processed paperboard. That is, in the case that the preset length of the paper box to be processed is greater than or equal to the distance between the first paper feeding module 321 and the second paper feeding module 322, the first transverse cutting module 331 is controlled to cut in the transverse direction at the appropriate time. After being cut in the transverse direction, the cut paperboard is continuously conveyed by the second paper feeding module 322 for paper output, and the first paper feeding module 321 no longer contacts the cut paperboard.

[0054] Specifically, the distance between the first transverse cutting module and the second transverse cutting module is equal to the distance between the first paper feeding module and the second paper feeding module.

[0055] In implementation, as shown in Figure 2B and Figure 2I the box making machine further comprises:

[0056] A transverse slotting and creasing module 34 is arranged between the first transverse cutting module 331 and the second paper feeding module 322. The transverse slotting and creasing module 34 has two slotting knives 341 arranged in the transverse direction. The two slotting knives 341 can move up and down and move towards and away from each other in the transverse direction. The two slotting knives 341 are kept apart when the closest distance of the two slotting knives 341 moving towards each other.

[0057] The control unit is further configured to: when the preset transverse slotting depth D is less than or equal to the length of the slotting knife 341, control the two slotting knives 341 to first move towards or away from each other, and then move downward to slot in the width direction of the paperboard to form a transverse slot 421.

[0058] The two slotting knives can move towards and away from each other in the transverse direction, and cooperate with various widths of the paperboard. When the width of the paperboard is small, the two slotting knives can move towards each other, so that the outer edges of the two slotting knives are consistent with the edges of the paperboard in the width direction. When the width of the paperboard is small, the two slotting knives can move away from each other, so that the outer edges of the two slotting knives are consistent with the edges of the paperboard in the width direction. In this way, paper boxes are processed using paperboards of different widths.

[0059] When the preset depth D of the transverse slotting of the carton is greater than the length of the slotting cutter 341, the control unit is used in combination with the first transverse cutting module and the second transverse cutting module to complete the processing. The control unit is also used to control the first transverse cutting module and the second transverse cutting module to cut at the transverse slotting position and the cutting length is the preset depth D of the slotting when the preset depth D of the transverse slotting is greater than the length of the slotting cutter.

[0060] Specifically, as shown in Figure 2B and Figure 2J The outer end of the slotting cutter 341 is large and the inner end is small, and the carton making machine further comprises two lower slotting cutters below the position of the paperboard, and the two lower slotting cutters have a gap therebetween. When the slotting cutter is slotting, the slotting cutter 341 moves downward, and a shearing fit is formed between the slotting cutter and the two lower slotting cutters to slot the paperboard.

[0061] In this way, the transverse slotting of the paperboard is a linear cutting surface action, and the slotting resistance is small.

[0062] Specifically, as shown in Figure 2J The slotting cutter 341 has a certain thickness, and the slotting edge 341-1 has two, and a groove is formed between the two slotting edges 341-1. When slotting, a long strip of paper scraps is cut off on the paperboard to form a gap with a certain width on the paperboard (illustrating the slotting of the carton on the carton), facilitating the forming of the carton.

[0063] Specifically, as shown in Figure 2J The outer end of the slotting cutter has a slotting cutter guide angle 341-2 to guide the smooth falling of the slotting cutter into the gap between the two lower slotting cutters; and the inner end of the slotting cutter has a slotting cutter cutting edge 341-3 to cut off the long strip of paper scraps on the paperboard and separate the long strip of paper scraps from the paperboard.

[0064] When the slotting cutter is slotting, the slotting cutter moves downward, and the outer end of the slotting cutter first performs slotting,

[0065] Specifically as shown in Figure 2B The transverse slotting creasing module further has a long strip-shaped creasing cutter 342, and the creasing cutter 342 and the slotting cutter are arranged above and below;

[0066] The creasing cutter 342 and the slotting cutter can move up and down as a whole, so that when the creasing cutter moves downward to form a transverse crease 422 on the paperboard, the slotting cutter moves downward and moves towards the paperboard to slot the paperboard.

[0067] The paperboard from the first paper feeding module passes between the slotting knife 341 and the two lower slotting knives. The transverse slotting and creasing module completes the transverse slotting and transverse creasing of the carton. In this way, the transverse slotting and creasing are realized by one downward movement of the transverse slotting and creasing module, which is more efficient. In the prior art, the transverse slotting and the transverse creasing are realized by one downward movement of each of the two components.

[0068] The structure of the paper changer will be described below.

[0069] In implementation, as shown in Figure 3A , the paper changer comprises:

[0070] a paper changer frame 21;

[0071] a paper changer channel module vertically slidingly connected in the paper changer frame 21, the paper changer channel module having a plurality of paper changer channels 221 installed in layers and at intervals, each of the paper changer channels 221 being used to clamp paperboard of a width;

[0072] a paper changer channel advancing and retreating mechanism used to move the selected paper changer channel 221 to a preset height and then move the selected paper changer channel 221 forward for subsequent paperboard processing procedures, and used to reset the selected paper changer channel 221 forward after the paperboard processing is completed.

[0073] Each paper changer channel clamps paperboard of a width, and the paper changer channel module realizes clamping of paperboard of multiple widths in layers in the vertical direction. The paper changer channel module is vertically slidingly connected in the paper changer frame, so that the paper changer channel module as a whole can move up and down in the vertical direction, thereby moving all the paperboard up and down in the vertical direction, and then moving the selected paperboard to a preset height. The paper changer channel advancing and retreating mechanism realizes moving the selected paper changer channel to a preset height and then moving the selected paper changer channel backward, i.e. driving the selected paperboard into the carton making machine for processing, and also realizes withdrawing the remaining selected paperboard out of the carton making machine after the paperboard processing is completed. The existence of the paper changer makes the selected paperboard enter the carton making machine for processing, and the withdrawal of the remaining selected paperboard out of the carton making machine through the paper changer and corresponding control is more efficient, convenient and highly automated.

[0074] In implementation, as shown in Figure 3A and Figure 3B , each of the paper changer channels 221 in each layer is arranged centrally in the transverse direction;

[0075] The transverse direction is the width direction of the paperboard clamped by the paper changer channel 221.

[0076] The paper changer channel is centrally arranged in the transverse direction, facilitating subsequent processing of the paperboard by the box making machine.

[0077] In an embodiment, as shown in Figure 3B Each of the paper changer channels 221 comprises:

[0078] A channel clamp mounting beam 221-1, two ends of the channel clamp mounting beam 221-1 are respectively provided with protruding channel limiting shafts 221-11;

[0079] Two paperboard channel clamps 221-2, which are fixed at the paperboard channel clamp mounting beam 221-1 and are symmetrical left and right;

[0080] A pressing cylinder 221-3, which corresponds to the paperboard channel clamp 221-2 and is fixed on the corresponding paperboard channel clamp 221-3, presses the paperboard above the paperboard channel clamp 221-2.

[0081] In an embodiment, as shown in Figure 3A And Figure 3B The paper changer channel module comprises:

[0082] The paper changer channel 221;

[0083] Two paper changer channel module side plates 222, each of which has a plurality of paper changer channel slides 223 arranged in layers and penetrating the paper changer channel module side plate, and the channel limiting shafts 221-11 protrude from the paper changer channel module side plate 222 through the paper changer channel slides 223;

[0084] The channel limiting shafts 221-11 can move back and forth along the paper changer channel slides 223.

[0085] The channel limiting shafts move back and forth along the paper changer channel slides 223, so that the paper changer channels can move back and forth, and the paper changer channel slides 223 play a guiding and limiting role.

[0086] Specifically, the length direction of the paper changer channel slide 223 is the front and back direction.

[0087] The channel limiting shafts and the paper changer channel slides cooperate, so that each layer of the paper changer channels has the ability to move back and forth, and the structure is simple.

[0088] In an embodiment, as shown in Figure 3C The paper changer further comprises a paper changer channel advancing and retreating mechanism, which comprises:

[0089] Two-section paper changer channel limiting groove 231, the guide direction of the paper changer channel limiting groove 231 is vertical; wherein the paper changer channel limiting groove 231 is fixed on the inner side of the paper changer rack; that is, the function of the paper changer rack includes installing the paper changer channel advancing and retreating mechanism;

[0090] Paper changer advancing and retreating air cylinder 234, fixed on the paper changer rack;

[0091] Movable limiting groove 232 fixed on the paper changer advancing and retreating air cylinder cylinder body, the guide direction of the movable limiting groove 232 is vertical, and the movable limiting groove 232 is arranged between the two-section paper changer channel limiting groove 231 so that the two-section paper changer channel limiting groove 231 and the movable limiting groove 232 are connected to form an up-down movement channel, and the channel limiting shaft 221-11 can move along the up-down movement channel;

[0092] Among them, the paper changer advancing and retreating air cylinder is a rodless air cylinder, and the cylinder body of the paper changer advancing and retreating air cylinder can reciprocate on the air cylinder shaft in the front-back direction.

[0093] When the channel limiting shaft 221-11 of the paper changer channel is located in the paper changer channel limiting groove 231, the position of the paper changer channel is locked and cannot move forward and backward. That is, the front-back position of the paper changer channel is kept.

[0094] No matter which layer of the paper changer channel has the channel limiting shaft 221-11 located in the movable limiting groove 232, the paper changer channel of this layer has the ability to move forward and backward. As long as the movable limiting groove 232 starts to move forward and backward, it can drive the paper changer channel of this layer to move forward and backward.

[0095] When it is necessary to send a certain paper changer channel to the box making machine of the carton processing machine, the paper changer channel lifting mechanism moves the channel limiting shaft of the selected paper changer channel into the movable limiting groove, the cylinder body of the paper changer advancing and retreating air cylinder moves backward to drive the movable limiting groove and the selected paper changer channel to move backward, and the paperboard of the selected paper changer channel is sent to the box making machine.

[0096] In implementation, as shown in Figure 3A and Figure 3C The paper changer further comprises a paper changer channel lifting mechanism, and the paper changer channel lifting mechanism comprises:

[0097] Vertically slidingly matched paper changer channel lifting slide rail 241 and paper changer channel lifting slide block 242, the paper changer channel lifting slide rail 241 is arranged on the inner side of the paper changer rack 21, and the paper changer channel lifting slide block 242 is fixed on the outer side of the paper changer channel module side plate 222. That is, another function of the paper changer rack is to install the paper changer channel lifting mechanism.

[0098] The paper changer passage lifting slide rail and the paper changer passage lifting slide block cooperate with each other, so that the paper changer passage module has the lifting capability as a whole. Specifically, the lifting of the paper changer passage module is realized by the paper changer passage module lifting motor.

[0099] In this way, the paper changer rack is used to fix the paper changer passage lifting mechanism and the paper changer passage advancing and retreating mechanism.

[0100] In the implementation, as shown in Figure 3A and Figure 3C , the paper changer passage lifting mechanism further comprises:

[0101] a passage entering detection sensor 251 and a passage exiting detection sensor 252;

[0102] a rodless air cylinder mounting seat, a front end of the rodless air cylinder mounting seat is provided with the passage entering detection sensor 251, and a rear end of the rodless air cylinder mounting seat is provided with the passage exiting detection sensor 252, so as to detect the slide block of the paper changer advancing and retreating air cylinder;

[0103] The control unit is further used to judge whether the paper changer passage reaches the position by detecting whether the slide block reaches the preset position:

[0104] When the passage entering detection sensor 251 detects the slide block of the paper changer advancing and retreating air cylinder, it is judged that the paper changer passage reaches the preset position;

[0105] After the carton processing is completed, when the passage exiting detection sensor 252 detects the slide block of the paper changer advancing and retreating air cylinder, it is judged that the paper changer passage retreats to the initial position, and the paper changer passage lifting action can be performed.

[0106] In this way, when the paper changer passage reaches the preset position, the control unit judges that the paper board realizes the correct paper feeding of the paper board, and the next step can be started. When the paper changer passage retreats to the initial position, the control unit judges that the paper changer passage is reset, and the lifting can be performed.

[0107] The passage entering detection sensor and the passage exiting detection sensor cooperate with the control unit to realize the judgment of whether the paper feeding is correct, realize the judgment of whether the paper changer passage is reset after the paper feeding is completed and whether the lifting can be performed, and the degree of automation is high, and the workload of the staff is reduced.

[0108] Specifically, as shown in Figure 3A , the bottom of the paper changer is provided with a mobile foot wheel 261.

[0109] The foot wheel enables the paper changer to be conveniently moved when the carton processing machine is installed and maintained.

[0110] Specifically, the paper changer channel lifting mechanism further comprises a paper changer channel lifting motor 243-1, a paper changer transmission synchronous wheel 243-2, a paper changer transmission synchronous belt 243-3, a paper changer transmission shaft 243-4, and a paper changer lifting synchronous belt 243-5; the paper changer channel lifting motor 243-1 drives the paper changer transmission synchronous wheel 243-2 and the paper changer transmission synchronous belt 243-3 to rotate, and the rotation is transmitted to the paper changer lifting synchronous belt 243-5 through the paper changer transmission shaft 243-4, so that the paper changer channel lifting slider 242 is lifted, thereby achieving the lifting of the whole paper changer channel module.

[0111] In the implementation, the first paper feeding module 321 and the second paper feeding module 322 have the same structure, as shown in Figure 4A The first paper feeding module and the second paper feeding module each comprise:

[0112] a plurality of sun wheel modules 323-1;

[0113] a paper feeding roller 323-2, the sun wheel modules 323-1 and the paper feeding roller 323-2 are arranged in an up-down manner, and the interval between the sun wheel modules 323-1 and the paper feeding roller 323-2 is used for the passage of paperboard; each of the sun wheel modules 323-1 can be moved up and down to move away from and press the paperboard above the paper feeding roller 323-2;

[0114] a paper feeding synchronous belt 323-3 and a paper feeding motor 323-4, the paper feeding synchronous belt 323-3 is synchronously connected to the output shaft of the paper feeding motor 324-4 and the paper feeding roller 323-2;

[0115] The control unit is further configured to select the number and position of the sun wheel modules to be moved downward according to the width of the selected paperboard.

[0116] The carton processing machine has paperboards of various widths to choose from. Correspondingly, when the width of the selected paperboard is the largest, all the sun wheel modules of the first paper feeding module are selected, and all the sun wheel modules are moved downward to press on the paperboard. When the width of the selected paperboard is smaller, part of the sun wheel modules of the first paper feeding module are selected, and only the selected sun wheel modules are moved downward to press on the paperboard. The first paper feeding module and the second paper feeding module with such a structure, in cooperation with the control unit, are more energy-saving and have less unnecessary energy loss.

[0117] The first paper feeding module is used to feed the paperboard from the paper changer into the inside of the carton making machine for processing. The second paper feeding module is used to feed the processed paperboard out of the carton making machine.

[0118] Specific process: after the paperboard reaches the first paper feeding module, the sun gear of the sun gear module falls and presses the paperboard, then the paper feeding motor of the first paper feeding module drives the first paper feeding roller to rotate through the synchronous wheel and the first synchronous belt mechanism. Under the cooperation of the sun gear module of the first paper feeding module and the paper feeding motor, the paperboard is accurately fed to the position.

[0119] In the implementation, as shown in Figure 4B 、 Figure 4C 、 Figure 4D and Figure 4E , the sun gear module 323-1 includes:

[0120] a U-shaped sun gear mounting frame 323-11, the vertical arm end of the sun gear mounting frame 323-11 has a downward mounting opening 323-12;

[0121] a plurality of sun gears 323-13 and a sun gear mounting shaft 323-14, each of the sun gears 323-13 is uniformly mounted on the sun gear mounting shaft 323-14;

[0122] a sun gear baffle 323-15, the sun gear baffle 323-15 has a sun gear baffle mounting hole;

[0123] wherein, the end of the sun gear mounting shaft 323-14 enters the mounting opening 323-12 from bottom to top, then the sun gear baffle mounting hole passes through the end of the sun gear mounting shaft 323-14 and the sun gear baffle 323-15 is fixed with the outside of the vertical arm of the sun gear mounting frame 323-11.

[0124] In this way, the cooperation of the sun gear mounting shaft 323-14, the mounting opening 323-12 of the vertical arm end of the sun gear mounting frame 323-11 and the sun gear baffle 323-15 realizes the quick installation and disassembly of the sun gear mounting shaft and the sun gears thereon, which is convenient for subsequent replacement of damaged sun gears.

[0125] Specifically, as shown in Figure 4B and Figure 4C , the sun gear module 323-1 further includes:

[0126] a sun gear cylinder 323-16 fixed on the outer top surface of the horizontal arm of the sun gear mounting frame 323-11 to drive the sun gear mounting frame 323-11 to move up and down.

[0127] Each sun gear module has a separate sun gear cylinder, so that the sun gears of each sun gear module can move up and down as a whole.

[0128] The structure of the longitudinal cutter of the longitudinal slitting and creasing module will be described below.

[0129] During implementation, such as Figure 2E , Figure 2F , Figure 2G and Figure 2H As shown, the longitudinal cutter 31 includes:

[0130] Longitudinal tool mount 311-1;

[0131] The longitudinal creasing roller 312-1 and the cutter mounting arm 313-11 are installed at a distance from front to back at the bottom of the longitudinal cutter mounting seat 311-1; wherein, the longitudinal creasing roller 312-1 is used to creasing the paperboard to form longitudinal creasing 424;

[0132] A cutter drive assembly 314 is connected to the lower part of the cutter mounting arm 313-11, and the cutter drive assembly 314 is inclined backward and downward from the lower part of the cutter mounting arm 313-11.

[0133] The longitudinal slitting blade 315-11 is connected to the lower end of the cutter drive assembly 314. The longitudinal slitting blade is used to longitudinally slit the cardboard to form a longitudinal slitting line 423.

[0134] The bottom surface of the cutter drive assembly 314 is a lower guide bottom surface 314-1 that slopes downward from front to back. The lower guide bottom surface 314-1 is used to guide the moving cardboard with the curled-up end after the crease along the lower guide bottom surface 314-1 to move under the longitudinal slitting blade 315-11.

[0135] The lower guide surface 314-1 slopes downwards from front to back, meaning the paper feed side is higher than the paper side. This prevents the cardboard from getting stuck due to warping or other reasons when it arrives; it also guides any warped cardboard along the lower guide surface 314-1. The longitudinal creasing roller 312-1, cutter mounting arm 313-11, and longitudinal slitting blade 315-11 are connected sequentially from front to back below the longitudinal cutter mounting seat. During the cardboard's forward-to-back movement, the longitudinal creasing roller 312-1 crimps the cardboard, and after the cardboard is crimped, the... Figure 2C The right end of the cardboard will curl up, with the curled-up end positioned at the lower guide surface 314-1. Because the lower guide surface of the cutter drive assembly slopes downwards from front to back, the curled-up end of the cardboard is pressed down from front to back, moving under the longitudinal slitting blade 315-11 for longitudinal slitting. This significantly reduces paper jams between the longitudinal pressure rollers and the longitudinal slitting blade.

[0136] During implementation, such as Figure 2C As shown, the rotation direction of the longitudinal slitting blade 315-11 is such that the conveying direction of the lower edge of the longitudinal slitting blade is consistent with the conveying direction of the cardboard 41, so as to guide the cardboard 41 to move under the longitudinal slitting blade 315-11.

[0137] The rotation direction of the longitudinal slitting cutter can be clockwise or counterclockwise to achieve the longitudinal slitting of the paperboard. However, when the paperboard just contacts the longitudinal slitting cutter, if the conveying direction of the lower edge of the longitudinal slitting cutter is consistent with the conveying direction of the paperboard from front to back, the longitudinal slitting cutter can guide the movement of the paperboard while playing a role in longitudinal slitting. That is, as shown in Figure 2C , the longitudinal slitting cutter 315-11 rotates counterclockwise in this view, which can also prevent the paperboard 41 from being stuck and ensure smooth passage of the paperboard.

[0138] Specifically, as shown in Figure 2C , when the longitudinal slitting cutter 315-11 is in the longitudinal slitting working position, the downward inclination angle of the lower guide bottom surface from front to back is greater than or equal to 5 degrees and less than or equal to 25 degrees.

[0139] The longitudinal slitting cutter has an initial position and a longitudinal slitting working position. When the longitudinal slitting cutter is in the initial position, the longitudinal slitting cutter is in a raised state, and the longitudinal slitting cutter does not perform longitudinal slitting on the paperboard. When the longitudinal slitting cutter is in the longitudinal slitting working position, the longitudinal slitting cutter is in a depressed state, and the longitudinal slitting cutter can perform longitudinal slitting on the paperboard.

[0140] In implementation, as shown in Figure 2B and Figure 2C , the longitudinal slitting cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 are spaced apart; wherein the sun gear of the second paper feeding module is used to feed the paperboard after longitudinal slitting and line pressing to output the paperboard.

[0141] Specifically, as shown in Figure 2B and Figure 2C , the gap between the longitudinal slitting cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 is less than or equal to 20 centimeters; or the gap between the longitudinal slitting cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 is greater than or equal to 1 millimeter and less than or equal to 200 millimeters.

[0142] As shown in Figure 2C , the gap between the longitudinal slitting cutter 315-11 and the sun gear 323-13 of the second paper feeding module 322 is the smaller gap 315-13 behind the longitudinal slitting cutter, and the paperboard 41 is pressed by the sun gear 323-13 of the second paper feeding module 322 after passing through the longitudinal slitting cutter 315-11, so that the paperboard cannot continue to be raised, thereby reducing the probability of paper jam between the longitudinal slitting cutter and the sun gear of the second paper feeding module.

[0143] In implementation, as shown in Figure 2E and Figure 2G , the longitudinal cutter further comprises:

[0144] The longitudinal pressing wheel cylinder 312-2 is fixed to the bottom of the longitudinal cutter mounting seat 311-1;

[0145] The pressing cylinder connecting plate 312-3 is fixed to the end of the piston rod of the longitudinal pressing wheel cylinder 312-2;

[0146] The pressure roller mounting base 312-41 is fixed to the bottom of the pressure cylinder connecting plate 312-3, and the longitudinal pressure roller 312-1 is rotatably connected to the pressure roller mounting base 312-41.

[0147] The creasing cylinder connecting plate and the creasing wheel mounting base are fixed as one unit. The longitudinal creasing wheel 312-1 is rotatably connected to the creasing wheel mounting base 312-41, and the creasing cylinder connecting plate is fixed to the end of the piston rod of the longitudinal creasing wheel cylinder 312-2. In this way, the piston rod of the longitudinal creasing wheel cylinder 312-2 can extend downwards and return to its original position relative to the longitudinal cutter mounting base. When the longitudinal creasing wheel needs to creasing the paperboard longitudinally, it extends downwards to creasing the paperboard. When longitudinal creasing is not needed, the longitudinal creasing wheel returns to its original position. Thus, with a simple structure, the downward extension and return of the longitudinal creasing wheel are achieved.

[0148] During implementation, such as Figure 2G As shown, the cutter drive assembly includes a cutter mounting shaft 314-33, and a longitudinal cutter drive gear 314-21, a longitudinal cutter transition gear 314-22, and a longitudinal cutter driven gear 314-23 that mesh sequentially; the longitudinal cutter drive gear 314-21 is connected to the lower part of the cutter mounting arm 313-11, and the cutter mounting shaft 314-33 and the longitudinal cutter driven gear 314-23 are fixed;

[0149] The longitudinal slitting blade 315-11 is detachably connected to the blade mounting shaft 314-33.

[0150] The longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 are in meshing transmission. The longitudinal cutter transmission gear is a power input gear, the longitudinal cutter driven gear is a power output gear, and the longitudinal cutter rotates under the drive of the cutter driven gear and the cutter mounting shaft, so that the longitudinal cutter transmission gear drives the rotation of the cutter mounting shaft and the longitudinal cutter 315-11. The three gears are in meshing transmission, which is compact and has good synchronism, so that the longitudinal cutter can rotate autonomously. The longitudinal cutter can rotate autonomously, the longitudinal cutter rotates at high speed, and the linear speed of the blade of the longitudinal cutter is much greater than the speed of the paperboard advancing. Below the longitudinal cutter is a longitudinal cutter comb that cooperates with the longitudinal cutter. The paperboard passes between the longitudinal cutter comb and the longitudinal cutter. The longitudinal cutter comb has uniformly distributed comb teeth like a comb. The upper edge of the comb tooth is arc-shaped, and the comb tooth is made of a material with elasticity. When the paperboard needs to be cut longitudinally, the longitudinal cutter falls, the blade of the longitudinal cutter falls into the comb tooth gap of the longitudinal cutter comb, completely cuts through the paperboard, and the comb teeth of the longitudinal cutter comb provide good support for the paperboard, so that the paperboard does not deform when subjected to cutting force.

[0151] In the implementation, as shown in Figure 2E and Figure 2G The cutter transmission assembly further includes a cutter gear box 314-41 and a cutter gear box cover 314-42. The cutter gear box and the cutter gear box cover form a cutter gear mounting box.

[0152] The longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 are inclined downward from front to back at the lower part of the cutter mounting arm 313-11 and arranged in the gear mounting box.

[0153] The bottom surface of the cutter gear box cover is a downwardly inclined guide bottom surface 314-1 from front to back.

[0154] In this way, the longitudinal cutter transmission gear 314-21, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 are arranged in the gear mounting box.

[0155] The three gears are arranged in the gear mounting box, so that the debris generated when the paperboard is processed is isolated outside the gear mounting box, reducing the impact on the gears; at the same time, the gears can be effectively lubricated.

[0156] In the implementation, the housing has three through holes, and a cutter gear box ball bearing is fixed in each through hole. The cutter gear box cover has a through hole, and a cutter gear box cover ball bearing is fixed in each through hole.

[0157] As shown in Figure 2GAs shown, the cutter transmission assembly further comprises:

[0158] The transmission gear positioning shaft 314-31 is fixed with the shaft hole of the longitudinal cutter transmission gear 314-21;

[0159] The transition gear mounting shaft 314-32 is fixed with the shaft hole of the longitudinal cutter transition gear 314-22;

[0160] The transmission gear positioning shaft 314-31, the transition gear mounting shaft 314-32 and the cutter mounting shaft 314-33 are respectively fixed in the inner rings of the cutter gear box ball bearing and the cutter gear box cover ball bearing.

[0161] The transmission gear positioning shaft 314-31 and the longitudinal cutter transmission gear 314-21 are fixed as a whole, and the transmission gear positioning shaft 314-31 is connected with the cutter gear box ball bearing and the cutter gear box cover ball bearing of the cutter gear box shell, so that the transmission gear positioning shaft 314-31 and the longitudinal cutter transmission gear 314-21 can rotate in the gear mounting box. Similarly, the longitudinal cutter transition gear 314-22 and the longitudinal cutter driven gear 314-23 can rotate in the gear mounting box.

[0162] The cutter gear box 314-41 and the cutter gear box cover 314-42 form a cutter gear mounting box, and the cutter mounting arm 313-11 is installed through the bearing and the transmission gear positioning shaft 314-31, that is, the cutter transmission assembly as a whole can rotate around the transmission gear positioning shaft 314-31.

[0163] In the implementation, as shown in Figure 2A 、 Figure 2D 、 Figure 2E and Figure 2G The longitudinal slitting and line pressing module further comprises:

[0164] The longitudinal cutter transmission shaft 316-11 is fixedly connected with the through hole shaft hole reserved at the center of the transmission gear positioning shaft 314-31;

[0165] The externally meshed longitudinal cutter driven gear 316-12 and the longitudinal cutter driving gear 316-13 are opposite in rotation direction;

[0166] The longitudinal cutter driven gear 316-12 is fixed at the end of the longitudinal cutter transmission shaft 316-11, and the longitudinal cutter driving gear 316-13 and the second paper feeding driving gear are connected through the second driving synchronous belt mechanism.

[0167] The box making machine has a second paper feeding motor below the position of the paperboard, and the output shaft of the second paper feeding motor is connected with the second driving synchronous belt mechanism.

[0168] The rotation direction of the longitudinal cutter driven gear 316-12, the longitudinal cutter transmission shaft 316-11 and the longitudinal cutter driven gear 314-21 is the same; the rotation direction of the longitudinal cutter driven gear 314-21 and the longitudinal cutter driven gear 314-23 is the same. The rotation direction of the longitudinal cutter driven gear 314-23 and the longitudinal cutter driving gear 316-13 is opposite, that is, the rotation direction of the longitudinal cutter driven gear 314-23 and the output shaft of the second paper feeding motor is opposite. The longitudinal cutter driven gear 314-23 rotates above the paperboard, and the second paper feeding motor rotates below the paperboard to feed the paperboard, so that the rotation direction of the longitudinal cutter driven gear 314-23 and the second paper feeding motor is opposite, but the conveying direction of the lower edge of the longitudinal cutter is consistent with the conveying direction of the second paper feeding motor to the paperboard.

[0169] Specifically, the longitudinal cutter transmission shaft 316-11 is designed as a hexagonal shaft, and the through hole in the center of the transmission gear positioning shaft 314-31 is a hexagonal hole, so that the longitudinal cutter transmission shaft 316-11 and the through hole in the center of the transmission gear positioning shaft 314-31 are fixedly connected. Therefore, power is transmitted from the second paper feeding motor to the longitudinal cutter transmission shaft 316-11, and then to the longitudinal cutter 315-11, so that the longitudinal cutter 315-11 is driven.

[0170] In the implementation, as shown in Figure 2F , Figure 2G and Figure 2H , the cutter mounting shaft 314-33 of the cutter transmission assembly penetrates the housing composed of the cutter gear box and the cutter gear box cover, and symmetrically extends out of the two sides of the housing composed of the cutter gear box and the cutter gear box cover.

[0171] The longitudinal cutter 315-11 can be detachably mounted at the two ends of the cutter mounting shaft 314-33.

[0172] In this way, the longitudinal cutter 315-11 can be individually mounted at either end of the cutter mounting shaft 314-33, and two longitudinal cutters 315-11 can also be mounted at the two ends of the cutter mounting shaft 314-33. This makes the longitudinal cutter 315-11 have multiple mounting possibilities and can be applied in more scenarios.

[0173] In the implementation, as shown in Figure 2F , Figure 2G and Figure 2HAs shown, the cutter transmission assembly is a symmetrical structure with the center line of the cutter mounting shaft 314-33 as the symmetry axis; the longitudinal cutter further comprises a line pressing wheel mounting shaft 312-42, which penetrates the line pressing wheel mounting seat and symmetrically extends out, and the longitudinal line pressing wheel 312-1 can be detachably mounted at either end and / or both ends of the line pressing wheel mounting shaft 312-42;

[0174] The longitudinal cutter is at least two, each longitudinal cutter is coaxially mounted on the longitudinal cutter transmission shaft, and the longitudinal slitting knives of two adjacent longitudinal cutters can be mounted on opposite sides so that the two longitudinal slitting knives are arranged adjacent to each other, and the longitudinal line pressing wheels of two adjacent longitudinal cutters can be mounted on opposite sides so that the two longitudinal line pressing wheels are arranged adjacent to each other.

[0175] The longitudinal cutter structure is symmetrical, and longitudinal line pressing wheels and longitudinal slitting knives can be installed on both sides for selective installation according to the needs of processing. This design enables the device to process ultra-thin cartons, i.e., when the longitudinal line pressing wheels and the longitudinal slitting knives are installed in opposite directions, the longitudinal line pressing wheels of two adjacent longitudinal cutters can be placed together, and the longitudinal slitting knives of two adjacent longitudinal cutters can be placed together.

[0176] When there are multiple longitudinal cutters, the longitudinal slitting knives of each longitudinal cutter can be installed on the same side of the cutter transmission assembly, in which case the distance between the longitudinal slitting knives is at least the thickness of the cutter transmission assembly. Alternatively, the longitudinal slitting knives of two adjacent longitudinal cutters can be installed on opposite sides so that the two longitudinal slitting knives are arranged adjacent to each other, in which case the distance between the two longitudinal slitting knives exceeds the thickness of the cutter transmission assembly. Therefore, the detachable installation of the longitudinal slitting knives 315-11 at both ends of the cutter mounting shaft 314-33 provides more possibilities for the distance between the longitudinal slitting of the carton processing machine and makes the carton processing machine more versatile.

[0177] As shown in Figure 1B and Figure 1C the transverse cutting line 425, the transverse slotting 421, the transverse line pressing 422, the longitudinal line pressing 424, and the longitudinal slitting line 423. The thickness of the carton is determined by the distance between the two longitudinal slitting lines 423, and the distance between the two longitudinal slitting lines 423 is determined by the distance between the two longitudinal slitting knives 315-11 of two adjacent longitudinal cutters. The arrangement of the two longitudinal slitting knives 315-11 of two adjacent longitudinal cutters adjacent to each other not only enables the processing of cartons with a larger thickness, but also enables the processing of cartons with a very small thickness. The minimum thickness of the carton is the distance between the two longitudinal slitting knives of two adjacent longitudinal cutters.

[0178] In implementation, as shown in Figure 2F the longitudinal cutter further comprises:

[0179] The longitudinal creasing wheel 312-1 is provided with a through hole, and a ball bearing is fixed in the through hole. A creasing wheel mounting shaft 312-42 is detachably fixed to the inner ring of the ball bearing, so that the longitudinal creasing wheel 312-1 can rotate around the creasing wheel mounting shaft 312-42 as the center.

[0180] In an embodiment, the longitudinal creasing wheel and the longitudinal slitting cutter mounted on the same side of the longitudinal cutter are located on the same straight line.

[0181] In this way, the paperboard is first longitudinally creased by the longitudinal creasing wheel, and then longitudinally slitted at the position of the longitudinal creasing.

[0182] In an embodiment, as shown in Figure 2E 、 Figure 2F and Figure 2G , the longitudinal cutter further comprises:

[0183] A longitudinal slitting cutter cylinder 315-12 is fixed to the bottom of the longitudinal cutter mounting seat 311-1 in front of and behind the cutter mounting arm 313-11. The piston rod of the longitudinal slitting cutter cylinder 315-12 is fixed to the cutter transmission assembly 314 to drive the longitudinal slitting cutter 315-11 to move downward and reset upward.

[0184] The longitudinal cutter mounting seat 311-1 is provided with a longitudinal cutter mounting seat through hole 311-21 at the position between the cutter mounting arm 313-11 and the longitudinal slitting cutter cylinder 315-12. The inlet pipe and outlet pipe of the longitudinal slitting cutter cylinder 315-12 pass through the longitudinal cutter mounting seat through hole 311-21.

[0185] Since the cutter transmission assembly can rotate around the transmission gear positioning shaft 314-31 as a whole, the longitudinal slitting cutter cylinder 315-12 controls the rotation of the cutter transmission assembly, thereby controlling the lifting of the longitudinal slitting cutter and completing the cutting action on the paperboard in the longitudinal direction.

[0186] The longitudinal cutter mounting seat 311-1 is provided with a longitudinal cutter mounting seat through hole 311-21, so that the inlet pipe and outlet pipe of the longitudinal slitting cutter cylinder 315-12 can be conveniently connected to the external air source through the longitudinal cutter mounting seat through hole 311-21. In this way, the space of the longitudinal cutter mounting seat 311-1 is fully utilized, and the overall wiring of the inlet pipe and outlet pipe of the longitudinal cutter is relatively simple.

[0187] In an embodiment, as shown in Figure 2E 、 Figure 2F and Figure 2GAs shown, the longitudinal creasing wheel cylinder 312-2 is fixed at the bottom of the longitudinal cutter mounting seat 311-1 and in front of the cutter mounting arm 313-11.

[0188] As shown, the cutter mounting arm 313-11 has a cutter mounting arm through hole 313-12 extending through front and back, and the air inlet pipe and air outlet pipe of the longitudinal creasing wheel cylinder 312-2 pass through the cutter mounting arm through hole 313-12 and the longitudinal cutter mounting seat through hole 311-21 in sequence.

[0189] The air inlet pipe and air outlet pipe of the longitudinal creasing wheel cylinder 312-2 are connected with the external air source through the cutter mounting arm through hole 313-12 and the longitudinal cutter mounting seat through hole 311-21, and the air inlet pipe and air outlet pipe of the longitudinal creasing wheel cylinder 312-2 and the air inlet pipe and air outlet pipe of the longitudinal slitting cutter cylinder 315-12 share the longitudinal cutter mounting seat through hole 311-21, so that the air inlet pipe and air outlet pipe are relatively simple as a whole.

[0190] The longitudinal creasing wheel is controlled up and down by the longitudinal creasing wheel cylinder 312-2. When it is necessary to crease the paperboard longitudinally, the longitudinal creasing wheel cylinder controls the longitudinal creasing wheel to fall and press the paperboard, and the longitudinal creasing wheel cooperates with the longitudinal creasing roller directly below to complete the longitudinal creasing on the paperboard.

[0191] In the implementation, as shown in Figure 2E , Figure 2F and Figure 2G , the longitudinal cutter further comprises:

[0192] A longitudinal cutter motor mounting member is fixed at the top of the longitudinal cutter mounting seat 311-1, and the longitudinal cutter motor mounting member has a longitudinal cutter motor mounting member through space extending through up and down, and the longitudinal cutter motor mounting member through space and the longitudinal cutter mounting seat through hole 313-12 are arranged up and down.

[0193] As shown, the air inlet pipe and air outlet pipe of the longitudinal creasing wheel cylinder and the air inlet pipe and air outlet pipe of the longitudinal slitting cutter cylinder passing through the longitudinal cutter mounting seat through hole pass through the longitudinal cutter motor mounting member through space from bottom to top.

[0194] In this way, the longitudinal cutter motor mounting member realizes the installation of the longitudinal cutter motor on one hand, and realizes the passing of the air inlet pipe and air outlet pipe on the other hand.

[0195] In the implementation, as shown in Figure 2E , Figure 2F and Figure 2G , the longitudinal cutter motor mounting member comprises:

[0196] Two flange support plates 317-11 are fixed in parallel on the top of the longitudinal cutter mounting seat 311-1;

[0197] A motor flange seat 317-12 is provided with a motor flange seat shaft hole and a motor flange seat wire passing hole 317-13 arranged in front and back, and the space between the two flange support plates 317-11 and the motor flange seat wire passing hole 317-13 are communicated to form a longitudinal cutter motor mounting wire passing space;

[0198] The longitudinal cutter further comprises a longitudinal cutter motor 317-2 fixed on the motor flange seat 317-12, and the output shaft of the longitudinal cutter motor 317-2 extends downward from the motor flange seat shaft hole.

[0199] The longitudinal cutter motor mounting composed of the two flange support plates 317-11 and the motor flange seat 317-12 has a simple structure, and not only realizes the installation of the longitudinal cutter motor, but also realizes the passing of the air inlet pipe and the air outlet pipe.

[0200] A plurality of wire passing holes are designed in the longitudinal cutter, including the longitudinal cutter mounting seat wire passing hole 311-21, the cutter mounting arm wire passing hole 313-12, and the motor flange seat wire passing hole 317-13, which are used to pass the air pipe and the motor wire of the longitudinal cutter, so as to facilitate the maintenance of the volume of the longitudinal cutter, and the spacing between adjacent longitudinal cutters is not affected by the air pipe and the wire. Moreover, such design makes the wire neat and facilitates the fixation of the air pipe and the motor wire.

[0201] The other structures of the longitudinal slitting and pressing module will be described below.

[0202] In the implementation, as shown in Figure 2D and Figure 2E The longitudinal slitting and pressing module further comprises:

[0203] A longitudinal cutter mounting beam 318-11 is fixed on the inner side of the box making machine frame 32.

[0204] A longitudinally longitudinally cutter gear 318-13 and a longitudinally longitudinally cutter gear 318-13 are engaged and matched, the longitudinally longitudinally cutter gear 318-13 is fixed on the outer circumferential surface of the output shaft of the longitudinally longitudinally cutter motor, and the longitudinally longitudinally cutter gear 318-12 is fixed on the side of the longitudinally longitudinally cutter mounting beam along the length direction of the longitudinally longitudinally cutter mounting beam 318-11.

[0205] The longitudinally longitudinally cutter motor 317-2 drives the longitudinally longitudinally cutter gear 318-13 to rotate, and the longitudinally longitudinally cutter gear 318-13 drives the longitudinally longitudinally cutter to move along the length direction of the longitudinally longitudinally cutter mounting beam 318-11.

[0206] The longitudinal cutter gear is a helical gear.

[0207] The longitudinal cutter motor, the longitudinal cutter gear, the longitudinal cutter rack and the longitudinal cutter mounting beam cooperate to realize the movement of the longitudinal cutter along the length direction of the longitudinal cutter mounting beam driven by the longitudinal cutter motor. In this way, the longitudinal cutter can move along the length direction of the longitudinal cutter mounting beam, the longitudinal creasing wheel of the longitudinal cutter can move up and down to realize the longitudinal creasing of the paperboard, and the longitudinal slitting cutter of the longitudinal cutter can move up and down to realize the longitudinal slitting of a part of the longitudinal creasing position.

[0208] In the implementation, as shown in Figure 2E and Figure 2G The longitudinal slitting and creasing module further comprises:

[0209] The slidingly fitted longitudinal cutter sliding block 318-21 is fixed on the top of the longitudinal cutter mounting seat 311-1 and above the longitudinal creasing wheel cylinder 312-2, and the longitudinal cutter sliding rail is fixed on the bottom of the longitudinal cutter mounting beam 318-11 along the length direction of the longitudinal cutter mounting beam 318-11, that is, the longitudinal cutter is slidingly connected to the longitudinal cutter mounting beam 318-11 through the longitudinal cutter sliding rail and the longitudinal cutter sliding block 318-21.

[0210] During the movement of the longitudinal cutter along the length direction of the longitudinal cutter mounting beam driven by the longitudinal cutter motor, the longitudinal cutter sliding block and the longitudinal cutter sliding rail slidingly cooperate to guide the direction of movement. The longitudinal cutter rack and the longitudinal cutter gear, and the longitudinal cutter sliding block and the longitudinal cutter sliding rail jointly act in such a way that the force balance during the movement of the longitudinal cutter along the length direction of the longitudinal cutter mounting beam is achieved, and the movement is smooth.

[0211] Specifically, the longitudinal cutter sliding block positioning plate is fixed between the two longitudinal cutter sliding blocks to position the longitudinal cutter sliding blocks and keep the relative distance between the two longitudinal cutter sliding blocks consistent, so that each longitudinal cutter can move smoothly on the longitudinal cutter sliding rail.

[0212] The structure of the paperboard stock bin will be described below. As shown in Figure 5 The paperboard stock bin 1 comprises a plurality of stock bins 11, a stock bin support 12, a surplus material warning sensor 13, a sensor support 14, a paperboard guide belt 15 and a paperboard guide belt support shaft 16. The surplus material warning sensor 13 is installed on the lower position of the stock bin support 12 through the sensor support 14, the stock bin is used to place a whole pile of continuous folded paperboard, and the paperboard guide belt 15 and the paperboard guide belt support shaft 16 cooperate to realize the layered arrangement of paperboards of various widths.

[0213] The main advantage of the paperboard bin is that it has a paperboard remaining warning function. When the remaining paperboard height is lower than the remaining warning sensor 13, a warning is issued to remind the staff to replenish the paperboard.

[0214] The other structures of the box making machine are described below.

[0215] Specifically, the box making machine further comprises a shell, an operation screen module, a paper pressing metal plate module, a slotting and line pressing module, and a paper discharging module.

[0216] The process of paperboard in the box making machine is as follows:
