[0055] In order to enable those in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0056] In this text, terms such as "upper, lower, inner, outer" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they should not be understood as absolute limitations on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0057] Please refer to Figure 1 , Figure 1 which is the schematic internal structure diagram of the carton forming machine provided by the embodiment of the present utility model.

[0058] As shown in the figure, in a specific embodiment, the carton forming machine provided by the present utility model is mainly divided into two major parts: the front-end equipment and the rear-end equipment, which are used in docking; among them, the front-end equipment is provided with a leading-edge paper feeding module 10, a rotary creasing module 20, and a rotary slotting module 30. The leading-edge paper feeding module 10 is used to convey cardboard to the subsequent modules, and the rotary creasing module 20 and the rotary slotting module 30 are used to crease and slot the cardboard; the rear-end equipment is provided with a mother-daughter creasing module 40, a longitudinal cutting module 50, a cutting module 60, and a vibrating knife module 70. The mother-daughter creasing module 40 is used to longitudinally crease the cardboard, the longitudinal cutting module 50 is used to longitudinally cut and trim the cardboard, the cutting module 60 is used to transversely cut and trim the cardboard (flatten and spray glue), and the vibrating knife module 70 is used to process special-shaped patterns on the cardboard. If the vibrating knife module 70 is replaced with a punching module or a punching module is added, the punching function can be achieved.

[0059] Please refer to Figures 2 to 6 , Figure 2 is Figure 1 the front view of the rotary creasing module and the rotary slotting module shown in Figure 3 is Figure 2 the rear view of the rotary creasing module and the rotary slotting module shown in Figure 4 is Figure 2 the axonometric view of the rotary creasing module and the rotary slotting module shown in the front-side perspective; Figure 5 is Figure 2 the axonometric view of the rotary creasing module and the rotary slotting module shown in the rear-side perspective; Figure 6 is Figure 2 the left view of the rotary creasing module and the rotary slotting module shown in

[0060] As shown in the figure, in a specific embodiment, the slotting and touching line mechanism of the carton forming machine provided by the utility model is provided with a rotary line touching line module 20 and a rotary slotting module 30. In the front and rear directions of cardboard conveying, the rotary line touching line module 20 and the rotary slotting module 30 are arranged side by side, the rotary line touching line module 20 is located on the front side, and the rotary slotting module 30 is located on the rear side.

[0061] The rotary line-touching module 20 is provided with a line-touching rubber roller 21, a line-touching knife roller 22 and a line-touching driving mechanism 23. A gap is formed between the line-touching rubber roller 21 and the line-touching knife roller 22 to pass through the cardboard. The outer surface of the line-touching knife roller 22 is provided with line-touching knives 221 distributed along the circumferential direction. The line-touching driving mechanism 23 is connected to the line-touching knife roller 22 through a chain and a sprocket transmission to drive the line-touching knife roller 22 to rotate. The line-touching knife roller 22 is driven by an independent motor, and different rotation speeds can be adjusted according to different sizes to achieve line-touching at different positions of the cardboard.

[0062] In this embodiment, the outer surface of the touch line knife roller 22 is provided with four touch line knives 221, and the four touch line knives 221 are evenly distributed in the circumferential direction. In this way, the touch line knife roller 22 can press a carton on the paperboard every time it rotates one circle (see Figure 13 ) The four horizontal crease lines A required on the paper.

[0063] Of course, in other embodiments, the outer surface of the touch line knife roller 22 may also be provided with one, two, three or more touch line knives 221. If only one touch line knife 221 is provided, a carton is pressed out on the paperboard (see Figure 13 ) when the four required transverse crease lines A are formed, the contact line knife roller 22 needs to rotate four times, and so on.

[0064] The rotary slotting module 30 is provided with a knife pad roller 31, a slotting knife roller 32, and a slotting drive mechanism 33. There are two slotting knife rollers 32, which are symmetrically installed on the slotting knife roller shaft 34. The outer surface of the slotting knife roller shaft 34 is provided with a slide rail 341 distributed along the circumferential direction. The slide rail 341 extends along the axial direction of the slotting knife roller shaft 34. The slotting knife roller 32 is a hollow structure, and its inner wall is provided with a slider 322 that slides with the slide rail. The two slotting knife rollers 32 are respectively matched with the slide rail 341 of the slotting knife roller shaft 34 through the slider 322, and can move laterally along the slotting knife roller shaft 34 and can rotate with the slotting knife roller shaft 34.

[0065] In other embodiments, the slotting cutter roller shaft 34 may also be designed as a transmission shaft such as a hexagonal shaft or a spline shaft, which can also realize the functions of axial movement and circumferential rotation of the slotting cutter roller 32 .

[0066] A gap is formed between the knife pad roller 31 and the slotting knife roller 32 to pass through the paperboard. The outer surface of the slotting knife roller 32 is provided with four slotting knives 321 distributed along the circumferential direction. The slotting drive mechanism 33 is connected to the slotting knife roller shaft 34 through a chain and a sprocket transmission to drive the slotting knife roller 32 to rotate. The slotting knife roller 32 is driven by an independent motor, and different speeds can be adjusted according to different sizes to achieve slotting at different positions of the paperboard.

[0067] Each slotting knife 321 has a first knife wall and a second knife wall which are parallel to each other. In the length direction, the outer end thereof is open and the inner end thereof is closed in a U shape, so as to be able to cut a narrow strip of cardboard material from both sides of the cardboard to form a transverse cutting groove B.

[0068] In this embodiment, the outer surface of the slotting knife roller 32 is provided with four slotting knives 321, and the four slotting knives 321 are evenly distributed in the circumferential direction. In this way, the slotting knife roller 32 can cut a carton on the cardboard every time it rotates one circle (see Figure 13 ) The four horizontal cutting grooves B required on the surface.

[0069] Of course, in other embodiments, the outer surface of the slotting knife roller 32 may also be provided with one, two, three or more slotting knives 321. If only one slotting knife 321 is provided, a carton is cut out of the paperboard (see Figure 13 ) when the four required transverse cutting grooves B are formed, the grooving knife roller 32 needs to rotate four times, and so on.

[0070] In actual production, some cartons need to be processed with bevels at both ends of the tongue edge (see Figure 13 ), in this regard, one of the four slotting knives 321 can be replaced with a corner cutting knife, or one of the four slotting knives 321 can be designed to have a shape with a corner cutting knife, such as an L shape, etc.

[0071] Moreover, the slotting knife 321 is detachably mounted on the outer surface of the slotting knife roller 32, and the corresponding slotting mold can be replaced according to different processing shapes.

[0072] In addition, in this embodiment, a laterally extending brush 35 is provided at the rear lower position of the slotting knife roller 32. By adding the brush 35, paper scraps on the slotting knife 321 can be cleaned to avoid affecting the next slotting and preventing waste from being brought into the equipment and causing accumulation.

[0073] Please refer to Figure 7 , Figure 7 This is a partial enlarged view of the swinging knife mechanism of the slotting module.

[0074] As shown in the figure, in order to process cardboard with different widths, the rotary grooving module 30 is provided with a swing knife mechanism. Through the swing knife mechanism, the symmetrically arranged grooving knife rollers 32 can be automatically swung according to the processing dimensions of different cardboard, realizing automated processing.

[0075] Specifically, the swing knife mechanism is provided with a swing knife motor 361, a swing knife lead screw 362, a swing knife nut 363 and a swing knife block 364. The swing knife lead screw 362 is located below the grooving knife roller shaft 32. The swing knife motor 361 is located at one end of the swing knife lead screw 362 and is connected to the swing knife lead screw 362 to drive the swing knife lead screw 362 to rotate. The swing knife nut 363 is installed on the swing knife lead screw 362 and is matched with the swing knife slide rail 366 through a swing knife slider 365. The swing knife block 364 is installed on the swing knife nut 363 by means of a transition connecting plate. One end of the grooving knife roller 32 is provided with an annular swing knife groove 323 corresponding to the swing knife block 364. The swing knife block 364 extends into the swing knife groove 323 for a certain distance. The swing knife block 364 can not only drive the grooving knife roller 32 to move horizontally together, but also will not interfere with the grooving knife roller 32 in the rotation direction and does not affect the normal rotation of the grooving knife roller 32.

[0076] Of course, in other embodiments, the swing knife motor 361 can also drive the swing knife block 364 to move through other means such as gears and racks, and then adjust the position of the grooving knife roller 32 to achieve rapid swing of the knife.

[0077] Please continue to refer to Figures 8 to 12 , Figure 8 is a side view of the grooving knife roller of the grooving module installed at the eccentric position of the driven wheel; Figure 9 is a partial enlarged view of one end of the grooving knife roller connected to the driving wheel and the cross coupling; Figure 10 is an axonometric view of the driving bearing part, the driving wheel and the cross coupling; Figure 11 is for Figure 10 side view; Figure 12 is for Figure 11 sectional view.

[0078] As shown in the figure, the creasing rubber roller 21 and the knife pad roller 31 are respectively provided with height adjusting mechanisms. By using the height adjusting mechanisms, the gaps between the creasing rubber roller 21 and the creasing knife roller 22 and between the knife pad roller 31 and the grooving knife roller 32 can be adjusted according to different cardboard materials or thicknesses.

[0079] Since the height adjusting mechanisms of the creasing rubber roller 21 and the knife pad roller 31 are substantially the same, only the knife pad roller 31 will be taken as an example below to illustrate the height adjusting mechanism.

[0080] Specifically, the height adjustment mechanism of the tool pad roller 31 is provided with an adjustment drive motor 371, a second driven gear 372 and a first driven gear 373. The number of the second driven gears 372 and the first driven gears 373 is two, respectively located at both ends of the tool pad roller 31. Both ends of the tool pad roller 31 are respectively installed on the first driven gear 373 through bearings 374 and are in the eccentric position of the first driven gear 373. The second driven gears 372 at both ends are coaxially connected through a transverse shaft 375. The adjustment drive motor 371 is arranged vertically, and the driving gear 376 at the output end of its reducer is meshed with the second driven gear 372 at one end for transmission. The second driven gear 372 is meshed with the first driven gear 373 for transmission. The diameters of the driving gear 376, the second driven gear 372 and the first driven gear 373 increase in sequence.

[0081] In this way, when the adjustment drive motor 371 rotates, it can drive the first driven gear 373 to rotate. Since the tool pad roller 31 is in the eccentric position of the first driven gear 373, its height relative to the grooving tool roller 32 will change. At the same time, it will shift to a certain extent in the front-back direction, but this shift will not affect the mutual cooperation relationship between the tool pad roller 31 and the grooving tool roller 32.

[0082] In this embodiment, although both ends of the tool pad roller 31 are directly installed on the eccentric position of the first driven gear 373 through bearings 374. However, in other embodiments, the tool pad roller 31 can also be indirectly installed on the eccentric position of the first driven gear 373. For example, a rotating body coaxially fixed with the first driven gear 373 can be set, and then both ends of the tool pad roller 31 are installed on the rotating body through bearings 374, and so on.

[0083] Since the height of the tool pad roller 31 is adjusted in an eccentric rotation manner, the problem of how to drive the tool pad roller 31 to rotate needs to be solved.

[0084] For this purpose, a driving wheel 38 and a cross coupling 39 can be configured for the cutter pad roller 31. The driving wheel 38 is a toothed sprocket wheel rotatably mounted on a driving bearing portion 381 at one end of the cutter pad roller 31. The cross coupling 39 has a first hub 391, a cross sliding disc 393 in the middle, and a second hub 392. A chute is provided on one side of the first hub 391 facing the cross sliding disc 393, a slider is provided on one side of the cross sliding disc 393 facing the first hub 391, a chute is provided on one side of the second hub 392 facing the cross sliding disc 393, and a slider is also provided on one side of the cross sliding disc 393 facing the second hub 392. The sliders on both sides of the cross sliding disc 393 are in a cross shape. The driving bearing portion 381, the driving wheel 38, the first hub 391, the cross sliding disc 393, and the second hub 392 are all hollow structures. The driving wheel 38 is connected to the first hub 391, and one end of the cutter pad roller 31 passes through the driving bearing portion 381, the driving wheel 38, the first hub 391, the cross sliding disc 393 and is connected to the second hub 392.

[0085] Of course, as a feasible implementation manner, the driving wheel 38 and the first hub 391 can also be of an integral structure and are integrally processed.

[0086] By providing the cross coupling 39, centering can be performed when the cutter pad roller 31 and the driving wheel 38 are not coaxial, so that the cutter pad roller 31 rotates concentrically under eccentric conditions.

[0087] To drive the driving wheel 38 of the line-touching rubber roller 21 and the cutter pad roller 31 to rotate, an upper roller driving motor 382 is provided in this embodiment (the installation components are not shown in the figure to avoid occlusion). It can drive the driving wheels 38 of the line-touching rubber roller 21 and the cutter pad roller 31 to rotate simultaneously through a chain (see the dotted line in the shape of a triangle in Figure 6 ).

[0088] Please refer to Figure 14 、 Figure 15 , Figure 14 For Figure 1 the isometric view of the mother-daughter wire pressing module shown in Figure 15 For Figure 1 the front view of the mother-daughter wire pressing module shown in

[0089] As shown in the figure, the mother-daughter wire pressing module 40 has four groups of upper and lower corresponding upper press wheel modules 41 and lower press wheel modules 42. Among them, the upper press wheel module 41 is provided with an upper frame 411 and an upper press wheel 412, and the lower press wheel module 42 is provided with a lower frame 421 and a lower press wheel 422. The upper press wheel 412 is installed on the upper press wheel beam 43 through the upper frame 411 and can slide horizontally along the upper press wheel beam 43. The lower press wheel 422 is installed on the lower press wheel beam 44 through the lower frame 421 and can slide horizontally along the lower press wheel beam 44.

[0090] The transmission shaft 45 is a hexagonal shaft with a hexagonal cross-section. A pulley 451 is provided at one end. The transmission shaft 45 passes through four lower pressing wheels 422 in the transverse direction. The lower pressing wheels 422 are provided with hexagonal shaft holes that can be sleeved on the transmission shaft 45. The lower pressing wheels 422 can move transversely along the transmission shaft 45 and can rotate together with the transmission shaft 45 when the transmission shaft 45 rotates.

[0091] The upper pressing wheel beam 43 is provided with an upper rack 46 extending along its length direction. Each upper pressing wheel module 41 is respectively provided with an upper driving motor 413 that drives it to move along the upper rack 46. The upper driving motor 413 is installed on the upper frame 411 and is provided with an upper gear 414 that meshes with the upper rack 46.

[0092] The lower pressing wheel beam 44 is provided with a lower rack 47 extending along its length direction. Each lower pressing wheel module 42 is respectively provided with a lower driving motor 423 that drives it to move along the lower rack 47. The lower driving motor 423 is installed on the lower frame 421 and is provided with a lower gear 424 that meshes with the lower rack 47.

[0093] Each upper pressing wheel module 41 is respectively provided with a cylinder 48. One end of the cylinder 48 is connected to the upper frame 411, and the other end of the cylinder 48 is connected to the upper pressing wheel mounting seat 415. When the cylinder 48 makes a telescopic movement, it can drive the upper pressing wheel 412 to act independently.

[0094] The two outermost groups of upper pressing wheel modules 41 are respectively provided with auxiliary paper pressing wheels 49 arranged coaxially with the upper pressing wheels 412. Similarly, the two outermost groups of lower pressing wheel modules 42 are respectively provided with auxiliary paper pressing wheels 49 arranged coaxially with the lower pressing wheels 422 (see Figure 19 ). By installing the auxiliary paper pressing wheels 49, the problem of partial warping of the cardboard can be effectively solved, and the phenomenon that the cardboard is scratched when it hits the slitting knife due to the edge warping during the processing can be avoided.

[0095] Please refer to Figure 16 、 Figure 17 , Figure 16 for Figure 2 the left view of the mother-daughter wheel wire pressing mechanism shown; Figure 17 is a schematic diagram of the lower pressing wheel of the lower pressing wheel module being a split and spliced structure.

[0096] As shown in the figure, the upper frame 411 is installed on the upper pressing wheel 43 beam through the first upper slide rail 416 and the second upper slide rail 417. The first upper slide rail 416 is located on the front side of the upper pressing wheel beam 43, and the second upper slide rail 417 is located at the bottom of the upper pressing wheel beam 43; the lower frame 421 is installed on the lower pressing wheel beam 44 through the first lower slide rail 426 and the second lower slide rail 427. Both the first lower slide rail 426 and the second lower slide rail 427 are located on the top of the lower pressing wheel beam 44.

[0097] The upper frame 411 and the lower frame 421 are respectively slidably engaged with the upper pressure wheel beam 43 and the lower pressure wheel beam 44 by double guide rails, which can ensure the structural stability of the upper pressure wheel module 41 and the lower pressure wheel module 42.

[0098] Specifically, the upper frame 411 is a U-shaped frame with an opening facing the rear side. It has a first horizontal connecting plate 4111, an upper vertical connecting plate 4112, and a second horizontal connecting plate 4113. A part of the upper pressure wheel beam 43 is located in the opening of the upper frame 411; the upper rack 46 is installed on the top of the upper pressure wheel beam 43 through an upper L-shaped bracket, and its tooth surface faces the front side; the upper driving motor 413 is vertically installed above the first horizontal connecting plate 4111, and its rotating shaft passes through the first horizontal connecting plate 4111 and is connected to the upper gear 414. The upper gear 414 is located below the first horizontal connecting plate 4111 so as to mesh with the upper rack 46.

[0099] A first upper slider 418 is provided inside the upper vertical connecting plate 4112 to slidably cooperate with the first upper slide rail 416 through the first upper slider 418. A second upper slider 419 is provided above the second horizontal connecting plate 4113 to slidably cooperate with the second upper slide rail 417 through the second upper slider 419. The upper pressure wheel 412 is located below the second horizontal connecting plate 4113.

[0100] The lower frame 421 is a U-shaped frame with an opening facing the rear side. It has a third horizontal connecting plate 4211, a lower vertical connecting plate 4212, and a fourth horizontal connecting plate 4213. A part of the lower pressure wheel beam 44 is located in the opening of the lower frame 421; the lower rack 47 is installed on the bottom of the lower pressure wheel beam 44 through a lower L-shaped bracket, and its tooth surface faces the front side; the lower pressure wheel 422 is located above the third horizontal connecting plate 4211. A first lower slider 428 and a second lower slider 429 are provided below the third horizontal connecting plate 4211 to slidably cooperate with the first lower slide rail 426 and the second lower slide rail 427 through the first lower slider 428 and the second lower slider 429. The lower driving motor 423 is vertically installed below the fourth horizontal connecting plate 4213, and its rotating shaft passes through the fourth horizontal connecting plate 4213 and is connected to the lower gear 422. The lower gear 422 is located above the fourth horizontal connecting plate 4213 so as to mesh with the lower rack 47.

[0101] Since the sliding installation methods of the upper frame 411 and the lower frame 421 are not exactly the same, the upper pressure wheel beam 43 and the lower pressure wheel beam 44 can be staggered by a certain distance in the front-rear direction to meet the alignment requirements of the upper pressure wheel 412 and the lower pressure wheel 422. At the same time, the upper rack 46 and the lower rack 47 are helical racks, and the upper gear 414 and the lower gear 424 are helical gears.

[0102] The lower pressing wheel 422 is of a split and spliced structure, which has a first lower pressing wheel half body 4221, a second lower pressing wheel half body 4222 and a hub 4223; the hub 4223 is rotatably installed on the lower pressing wheel mounting seat 4224, and the inner hole of the hub 4223 is a hexagonal hole so as to be slidably matched with the transmission shaft 45 and driven to rotate by the transmission shaft 45. The first lower pressing wheel half body 4221 and the second lower pressing wheel half body 4222 can be respectively fixed to the end face of the hub 4223 by screws, so as to be spliced into a complete circle. The inner hole after the two are spliced can be a round hole for passing through the transmission shaft 45. When it is necessary to remove the lower pressing wheel 422, loosening the screws can remove the first lower pressing wheel half body 4221 and the second lower pressing wheel half body 4222 from the hub 4223.

[0103] Since the lower pressing wheel 422 is mounted on the relatively long transmission shaft 45, it is very cumbersome to replace the traditional lower pressing wheel 422, and the whole mechanism needs to be disassembled to replace the lower pressing wheel. After the lower pressing wheel 422 in this embodiment is designed as a spliced structure, when replacing the lower pressing wheel 422, the hub 4223 does not need to be replaced, but only the first lower pressing wheel half body 4221 and the second lower pressing wheel half body 4222 on one side of the hub 4223 need to be replaced, which can realize the quick disassembly and installation of the lower pressing wheel 422.

[0104] Please continue to refer to Figure 18 、 Figure 19 , Figure 18 is Figure 17 the partial enlarged view of part I in Figure 19 is the schematic structural view of the outermost upper pressing wheel and lower pressing wheel provided with auxiliary paper pressing wheels.

[0105] As shown in the figure, the upper pressing wheel 412 and the lower pressing wheel 422 press the cardboard in the form of a parent and child wheel. When the cardboard passes between the upper pressing wheel 412 and the lower pressing wheel 422, the upper pressing wheel 412 is used to press the front side of the cardboard, and the lower pressing wheel 422 is used to press the back side of the cardboard to form the creases required when the cardboard is folded into a carton.

[0106] The surface of the upper pressing wheel 412 is provided with two first annular protrusions a distributed at intervals, and the surface of the lower pressing wheel 422 is provided with a second annular protrusion b. The second annular protrusion b is axially located between the two first annular protrusions a. A third annular protrusion c spaced from it is respectively provided on both sides of the second annular protrusion b. The height and width of the third annular protrusion c are both smaller than those of the second annular protrusion b.

[0107] Through the cooperation of the first annular protrusion a, the second annular protrusion b and the third annular protrusion c, a crease with a single line below and a double line above can be pressed out, and a more ideal pressing line effect can be obtained.

[0108] Since the upper pressure wheel module 41 and the lower pressure wheel module 42 respectively use independent motors to drive the upper pressure wheel 412 and the lower pressure wheel 422, each of the upper pressure wheel 412 and the lower pressure wheel 422 can move independently, greatly improving the swing speed and swing accuracy when the upper pressure wheel 412 and the lower pressure wheel 422 move horizontally. Quick adjustment can be achieved, so that when processing cartons, adjustment can be carried out quickly, reducing the time required for adjustment and further improving production efficiency.

[0109] Please refer to Figure 20 、 Figure 21 、 Figure 22 , Figure 20 is an axonometric view of the vibrating knife module; Figure 21 is Figure 20 the side view of the vibrating knife module shown; Figure 22 is Figure 20 the front view of the vibrating knife module shown.

[0110] As shown in the figure, the vibrating knife module 70 is mainly composed of a vibrating knife bracket 72, a vibrating knife 73, a knife die 74, etc. The entire vibrating knife module 70 is installed on the cross beam 71 and can move horizontally along the cross beam 71.

[0111] Specifically, a vertical X-axis motor 75 is installed at the upper end of the vibrating knife bracket 72. A gear is installed at the power output end of the X-axis motor 75 and is meshed with a rack on the cross beam 71 through the gear, thereby driving the vibrating knife module 70 to move horizontally along the X-axis direction.

[0112] The vibrating knife bracket 72 is installed on the first slide rail and the second slide rail on the cross beam 71 through the first slider 761 and the second slider 762, and the structure is more stable. The vibrating knife 73 is installed on one side of the vibrating knife bracket 72 through a lifting mechanism and can move up and down relative to the vibrating knife bracket 72.

[0113] Specifically, the vibrating knife 73 has components such as a rotating seat, a protective cover, and a pressing paper board. A vertical Z-axis motor 77 is installed at the upper end of the vibrating knife bracket 72. The vibrating knife 73 is installed on the lifting seat 78, and the Z-axis motor 77 can drive the vibrating knife 73 to move up and down along the lifting seat 78 through a screw-nut mechanism.

[0114] The knife die 74 is installed on the other side of the vibrating knife bracket 72. The air cylinder 79 is used to drive the knife die 74 to move up and down. The knife die 74 is installed on the knife die fixing plate through the knife die mounting seat, and the knife die fixing plate is installed at the lower end of the piston rod of the air cylinder 79.

[0115] The knife die 74 can have various different shapes. After the knife die 74 is selected, under the drive of the air cylinder 79, the required shape can be directly cut out or pressed out on the cardboard to assist the vibrating knife 73 to complete some special graphics. Moreover, the processing speed of the stamping of the air cylinder 79 is faster than that of the vibrating knife 73.

[0116] The above embodiments are only the preferred solutions of the present utility model, and are not specifically limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation manners. For example, the up-and-down positions of the line-touching rubber roller 21 and the line-touching cutter roller 22, the up-and-down positions and the sequence of the cutter pad roller 31 and the grooving cutter roller 32 can be interchanged. Or, the line-touching cutter 221 and the grooving cutter 321 are non-uniformly distributed in the circumferential direction. Or, the driving wheel 38 adopts a synchronous belt wheel, and so on. Since there are many possible implementation manners, they will not be exemplified one by one here.

[0117] The processing principle and process of the present utility model are as follows:

[0118] Place the cardboard on the platform of the leading-edge paper feeding module 10, and send a single piece of cardboard into the equipment by means of negative pressure adsorption;

[0119] When the cardboard passes through the rotary line-touching module 20, when the line-touching cutter 221 rotates to be tangent to the upper line-touching rubber roller 21, a horizontal line will be pressed at the specified position;

[0120] When the cardboard passes through the rotary grooving die 30 group, when the grooving cutter 321 rotates to be tangent to the upper cutter pad roller 31, a cutting groove is punched at the corresponding horizontal position (in most cases, the grooving position is collinear with the line-touching position, and in special cases, only line-touching or only grooving is performed);

[0121] When the cardboard passes through the mother-and-son wheel module 40, longitudinal creases are pressed on the cardboard by the upper pressing wheel 412 and the lower pressing wheel 422;

[0122] When the cardboard passes through the longitudinal cutting module 50, the longitudinal cutting knife is controlled by a cylinder to lift and lower. After descending, it cooperates with the lower knife comb to complete the cutting action. When the cardboard moves below the longitudinal cutting knife, the control system controls the corresponding slitting knife to fall and lift to achieve cutting;

[0123] When the cardboard passes through the cutting module 60, the motor of the cutting module 60 drives the cutting knife to move horizontally through a synchronous belt. When the cardboard reaches the specified position, cutting is achieved. The cutting knife module 60 can be equipped with a flattening wheel and a cold glue gun to achieve the functions of flattening and spraying glue on the cardboard;

[0124] When the cardboard moves below the vibrating knife 73 of the vibrating knife module 70, the vibrating knife module 70 cooperates with the rotating roller to achieve cutting of any shape. The vibrating knife module 70 can be replaced or equipped with a punching module to achieve various functions.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
