[0040] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0041] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.
[0042] Please refer to Figures 1 to 5 , Figure 1 A front view of a slotting and contacting mechanism of a carton forming machine provided in the first embodiment of the utility model; Figure 2 for Figure 1 The rear view of the slotting and contacting mechanism of the carton forming machine shown; Figure 3 for Figure 1 The axonometric view of the slotting and contacting mechanism of the carton forming machine shown is taken from the front side perspective; Figure 4 for Figure 1 The axonometric view of the slotting and contacting mechanism of the carton forming machine shown is taken from the rear side perspective; Figure 5 for Figure 1 The left view of the slotting and touching mechanism of the carton forming machine is shown.
[0043] As shown in the figure, in a specific embodiment, the carton forming machine slotting and touching line mechanism provided by the utility model is provided with a touching line module 20 and a slotting module 30. In the front and rear directions of cardboard conveying, the touching line module 20 and the slotting module 30 are arranged side by side, the touching line module 20 is located on the front side, and the slotting module 30 is located on the rear side.
[0044] The 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 paperboard. 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 paperboard.
[0045] 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 12) The four horizontal crease lines A required on the paper.
[0046] 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 12 ) when the four required transverse crease lines A are formed, the contact line knife roller 22 needs to rotate four times, and so on.
[0047] The 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.
[0048] 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 .
[0049] 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.
[0050] 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.
[0051] 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 12 ) The four horizontal cutting grooves B required on the surface.
[0052] 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 12When making the four required transverse cutting grooves B, the grooving cutter roller 32 needs to rotate four times, and so on.
[0053] In actual production, some cartons need to have cut corners processed at both ends of the tongue edge (see Figure 12 ). For this, one of the four grooving cutters 321 can be replaced with a corner cutter, or one of the four grooving cutters 321 can be designed in the shape of a corner cutter, such as an L shape, etc.
[0054] Moreover, the grooving cutter 321 is detachably installed on the outer surface of the grooving cutter roller 32, and the corresponding grooving die can be replaced according to different processing shapes.
[0055] In addition, in this embodiment, a laterally extending brush 35 is provided at the lower rear position of the grooving cutter roller 32. By adding the brush 35, the paper scraps on the grooving cutter 321 can be cleaned, avoiding affecting the next grooving and preventing waste accumulation by being carried into the equipment interior.
[0056] Please refer to Figure 6 , Figure 6 which is a partial enlarged view of the swing cutter mechanism of the grooving module.
[0057] As shown in the figure, in order to be able to process cardboard of different widths, the grooving module 30 is provided with a swing cutter mechanism. Through the swing cutter mechanism, the symmetrically arranged grooving cutter rollers 32 can perform automatic swing cutting according to different cardboard processing dimensions, realizing automated processing.
[0058] Specifically, the swing cutter mechanism is provided with a swing cutter motor 361, a swing cutter lead screw 362, a swing cutter nut 363 and a swing cutter block 364. The swing cutter lead screw 362 is located below the grooving cutter roller shaft 32. The swing cutter motor 361 is located at one end of the swing cutter lead screw 362 and is connected to the swing cutter lead screw 362 to drive the swing cutter lead screw 362 to rotate. The swing cutter nut 363 is installed on the swing cutter lead screw 362 and is matched with the swing cutter slide rail 366 through a swing cutter slider 365. The swing cutter block 364 is installed on the swing cutter nut 363 by means of a transition connecting plate. A circular swing cutter groove 323 corresponding to the swing cutter block 364 is provided at one end of the grooving cutter roller 32. The swing cutter block 364 extends into the swing cutter groove 323 for a certain distance. The swing cutter block 364 can not only drive the grooving cutter roller 32 to move horizontally therewith, but also will not interfere with the grooving cutter roller 32 in the rotation direction and does not affect the normal rotation of the grooving cutter roller 32.
[0059] Of course, in other embodiments, the swing cutter motor 361 can also drive the swing cutter block 364 to move through other means such as gears and racks, and then adjust the position of the grooving cutter roller 32 to achieve rapid swing cutting.
[0060] Please continue to refer to Figures 7 to 11 , Figure 7Side view of the grooving cutter roller of the grooving module installed at the eccentric position of the driven wheel; Figure 8 Partial enlarged view of one end of the grooving cutter roller connected to the driving wheel and the cross coupling; Figure 9 Axonometric view of the driving bearing part, the driving wheel and the cross coupling; Figure 10 For Figure 9 Side view; Figure 11 For Figure 10 Cross-sectional view.
[0061] 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 cutter roller 22 and between the knife pad roller 31 and the grooving cutter roller 32 can be adjusted according to different cardboard materials or thicknesses.
[0062] Since the height adjusting mechanisms of the creasing rubber roller 21 and the knife pad roller 31 are substantially the same, only the height adjusting mechanism of the knife pad roller 31 will be described below.
[0063] Specifically, the height adjusting mechanism of the knife pad roller 31 is provided with an adjusting drive motor 371, a second driven gear 372 and a first driven gear 373. The number of the second driven gear 372 and the first driven gear 373 is two each, and they are respectively located at both ends of the knife pad roller 31. Both ends of the knife 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 by a transverse shaft 375. The adjusting drive motor 371 is arranged vertically, and the driving gear 376 at the output end of its reducer meshes with the second driven gear 372 at one end for transmission. The second driven gear 372 meshes 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.
[0064] In this way, when the adjusting drive motor 371 rotates, it can drive the first driven gear 373 to rotate. Since the knife pad roller 31 is in the eccentric position of the first driven gear 373, its height relative to the grooving cutter 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 knife pad roller 31 and the grooving cutter roller 32.
[0065] In this embodiment, although both ends of the knife pad roller 31 are directly installed on the eccentric position of the first driven gear 373 through bearings 374. However, in other embodiments, the knife 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 knife pad roller 31 are installed on the rotating body through bearings 374, and so on.
[0066] Since the cutter pad roller 31 adjusts its height in an eccentric rotation manner, it is necessary to solve the problem of how to drive the cutter pad roller 31 to rotate.
[0067] For this, 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 and is rotatably installed 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 disk 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 disk 393, a slider is provided on one side of the cross sliding disk 393 facing the first hub 391, a chute is provided on one side of the second hub 392 facing the cross sliding disk 393, and a slider is also provided on one side of the cross sliding disk 393 facing the second hub 392. The sliders on both sides of the cross sliding disk 393 are in a cross shape. The driving bearing portion 381, the driving wheel 38, the first hub 391, the cross sliding disk 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 disk 393 and is connected to the second hub 392.
[0068] Of course, as a feasible implementation manner, the driving wheel 38 and the first hub 391 can also be of an integral structure, and the two are integrally processed.
[0069] By setting 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 the condition of eccentricity.
[0070] In order 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), and 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.
[0071] 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 cutters 221 and the grooving cutters 321 are non-uniformly distributed in the circumferential direction, or, the driving wheel 38 adopts a synchronous pulley, and so on. Since there are many possible implementation manners, they will not be exemplified one by one here.
[0072] When processing cardboard, the cardboard first passes through the creasing module 20. The creasing driving mechanism 23 provides power to the creasing cutter roller 22. When the creasing cutter 221 rotates to be tangent to the upper creasing rubber roller 21, the creasing cutter 221 and the creasing rubber roller 21 squeeze the corresponding position of the cardboard, and a horizontal line A will be pressed at the corresponding position to achieve the creasing function. Similarly, when the cardboard passes through the slotting module 30, the slotting driving mechanism 33 provides power to the slotting cutter roller 32. When the slotting cutter 321 rotates to be tangent to the upper tool pad roller 31, a cutting groove B is punched at the corresponding horizontal position to achieve the slotting function.
[0073] It should be noted here that in most cases, the slotting position is collinear with the creasing position. In special cases, only creasing or only slotting is performed.
[0074] The slotting and creasing mechanism of the carton forming machine provided by the present utility model has been introduced in detail above. 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 pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still 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.
