Description

A transverse slotting and indentation assembly and transverse slotting and indentation module Technical Field

[0001] This utility model relates to the field of carton machine technology, and in particular to a transverse slotting and creasing assembly and a transverse slotting and creasing module. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, typically used as wrapping materials for goods or as protective outer layers for items. During production, cardboard boxes are formed by bending cardboard. To ensure a completely sealed box, several grooves are cut at both ends of the cardboard to facilitate folding and sealing. The structure used for transverse grooving and creasing is called a transverse grooving and creasing assembly. The grooving portion of this assembly typically consists of a cutter shaft and rollers, or two cutter shafts with grooving blades that groove the cardboard through rolling. The creasing portion is usually formed by creasing blades mounted on the cutter shafts. However, different models and sizes of cardboard boxes currently on the market require different lengths of grooving or creasing, necessitating the replacement of upper cutter shafts of varying lengths, which is inconvenient and inefficient. Furthermore, when cardboard thickness varies, the spacing between the upper and lower creasing blades needs to be adjusted to accommodate different thicknesses. This requires assembling and disassembling the creasing blades along with the cutter shaft, which is time-consuming, labor-intensive, and lacks precision. Summary of the Invention

[0003] The purpose of this utility model is to design a horizontal slotting and indentation component and a horizontal slotting and indentation module to overcome the shortcomings of the above-mentioned technologies.

[0004] This utility model designs a transverse grooving and indentation assembly, comprising: a bracket; a roller connected to the bracket; a rotating shaft arranged parallel to the roller; at least one cutter shaft sequentially axially connected to the rotating shaft and rotating with the rotating shaft, each cutter shaft being capable of reciprocating axial movement along the rotating shaft; a grooving cutter disposed on the outer periphery of the cutter shaft and arranged axially along the cutter shaft; and an indentation cutter mounted on the rotating shaft, the indentation cutter performing indentation relative to the roller as the rotating shaft rotates.

[0005] In a further optimization, the transverse grooving assembly also includes a slide rail coaxial with the roller and mounted on a bracket, with a slider slidably connected to the slide rail and the slider being connected to the cutter shaft.

[0006] In a further optimization, the bracket is also provided with a lead screw pair, in which the lead screw is arranged along the slide rail, and the nut in the lead screw pair is connected to the slider, so that the slider reciprocates along the slide rail under the drive of the lead screw pair, and the cutter shaft reciprocates with the slider.

[0007] Further optimization involves a fixing hole in the center of the cutter shaft, through which the cutter shaft is fitted onto the rotating shaft.

[0008] Further optimization involves providing an axial mounting groove on the outer wall of the cutter shaft, a mounting hole on the slotted cutter, a fastener inside the mounting hole, and the top of the fastener passing through the mounting groove and fixed to the bottom surface of the mounting groove, thereby connecting the slotted cutter to the cutter shaft.

[0009] Further optimization involves providing multiple parallel mounting grooves on the outer wall of the cutter shaft, and multiple slotted cutters spaced apart along the circumference of the cutter shaft. Each slotted cutter includes a base and a blade located on the base. The base is connected to the mounting groove by fasteners, and the bottom surface shape of the base is adapted to the shape of the outer wall of the cutter shaft. The clearance groove is located in the center of the linear blade and penetrates the base.

[0010] Further optimization involves a long, narrow blade that is integrally fixed to the base, with evenly distributed buffer blocks on both sides of the blade.

[0011] Further optimization involves adjusting the position of the roller and the rotating shaft relative to the support, thereby making the relative distance between the roller and the rotating shaft adjustable.

[0012] Further optimization involves adjusting the position of the grooving cutter or indentation cutter relative to the corresponding rotating shaft, thereby adjusting the relative distance between the roller and the grooving cutter or indentation cutter.

[0013] Preferably, the cutter shaft and / or the grooving cutter are provided with a clearance groove for avoiding the indentation cutter, and the top of the indentation cutter is lower than the top of the grooving cutter.

[0014] Preferably, when the number of the grooving cutters (5) is two or more, the relative distance between the grooving cutters (5) and the grooving cutters (5) is adjustable.

[0015] Preferably, when there are two or more indentation tools (10), the relative distance between the indentation tools (10) can be adjusted.

[0016] Preferably, the combination of roller, shaft, cutter shaft and grooving cutter can form a horizontal grooving group; the combination of roller, shaft and indentation cutter can form a horizontal indentation group. The horizontal grooving group and the horizontal indentation group can be freely combined to achieve different arrangements and combinations of grooving and indentation processes.

[0017] This utility model designs a transverse slotting and creasing module, including two rotating shafts in the above-mentioned transverse slotting and creasing assembly. Each of the two rotating shafts is equipped with a creasing knife, and a creasing space is formed between the creasing knives of the two rotating shafts to creasing the paperboard that passes through.

[0018] Preferably, the two rotating shafts are provided with a driving mechanism, the driving mechanism including a transmission structure connected to the end of the rotating shaft, the transmission structure being connected to a first driving member, the first driving member driving the rotating shaft to rotate through the transmission structure.

[0019] In a further optimization, the drive mechanism also includes a lifting structure mounted on a bracket. The lifting structure is located at both ends of the rotating shaft, and the two lifting structures are connected by a synchronous rod to achieve radial linear movement of the rotating shaft, thereby making the radial distance between the two rotating shafts adjustable.

[0020] The technical advantage of this utility model is that it includes a roller and a rotating shaft parallel to and coaxial with the roller. A cutter shaft is mounted on the rotating shaft, and a grooving cutter is mounted on the cutter shaft. Grooving is achieved by the relative rotation of the cutter shaft and the roller between them. The rotating shaft also has a creasing cutter, which corresponds one-to-one with the grooving cutter. The grooving cutter has a clearance groove to avoid the creasing cutter, ensuring that grooving and creasing are completed simultaneously when the rotating shaft rotates, following the sequence of grooving followed by creasing. Simultaneously, the cutter shaft can move axially along the rotating shaft. When there are two cutter shafts, they are respectively fitted at the two ends of the rotating shaft. The two cutter shafts are slidably connected to a bracket via a transmission method combining guide rails and lead screws, allowing the two cutter shafts to reciprocate relative to each other along the rotating shaft. The spacing between the individual blade shafts is adjustable, thus meeting the slotting requirements at different positions without needing to stop the machine to adjust the cardboard, improving slotting efficiency. The design of the rotating shaft makes the blade shaft more stable during movement, and one rotating shaft can simultaneously drive two or more blade shafts to rotate, resulting in a more compact structure. When there are three or more blade shafts on the same rotating shaft, each blade shaft can move independently along the rotating shaft, realizing the adjustment of the spacing between adjacent blade shafts. In addition, one roller corresponds to one rotating shaft, and one rotating shaft can be fitted with one or more blade shafts. There can be two or more rollers, and each roller is equipped with a corresponding rotating shaft. Each rotating shaft can be equipped with a creasing knife or a blade shaft as needed, so that creasing and slotting can be performed separately and independently, which is very convenient.

[0021] When there are two rotating shafts, they can be grouped together. Each rotating shaft is individually controlled by a drive mechanism, allowing the two shafts to rotate relative to each other, thus achieving the creasing action. The drive mechanism can also control the rotating shafts to move radially back and forth, making the distance between the two rotating shafts adjustable, thereby enabling creasing of paperboards of different thicknesses. The overall structure is simple, easy to implement, reliable, and stable. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0032] Example 1

[0033] This utility model provides a transverse slotting and indentation assembly, which includes a bracket 1. The bracket 1 is rotatably connected to a roller 2. In this embodiment, there are two rollers 2. The rollers are driven to rotate by a driving component such as a motor. The bracket 1 is also rotatably connected to a rotating shaft 3. The rotating shaft 3 is parallel to and coaxially arranged with the roller 2. There are also two rotating shafts 3, which are arranged corresponding to the roller 2. The two rotating shafts 3 are also parallel to each other.

[0034] One of the rotating shafts 3 is provided with at least one cutter shaft 4. The cutter shaft 4 has a fixing hole in the center. The cutter shaft 4 is sleeved on the rotating shaft 3 through the fixing hole. When there are multiple cutter shafts 4, they are sleeved on the same rotating shaft 3 in sequence along the axial direction, so that multiple cutter shafts 4 can rotate with the rotating shaft 3 at the same time.

[0035] The transverse grooving assembly also includes a slide rail 6 coaxial with the roller 2 and mounted on the bracket 1. A slider 7 is slidably fitted on the slide rail 6, and the slider 7 is connected to the cutter shaft 4, so that the cutter shaft 4 can not only rotate with the rotating shaft 3, but also reciprocate along the rotating shaft 3 under the drive of the slider 7. The bracket 1 is also provided with a lead screw pair 8, in which the lead screw is set along the slide rail 6 and is driven to rotate by a drive mechanism. The nut in the lead screw pair 8 is connected to the slider 7, so that the slider 7 reciprocates along the slide rail 6 under the drive of the lead screw pair 8. The cutter shaft 4 is rotatably connected to the slider 7 and reciprocates along the slider 7, so that the cutter shaft 4 can reciprocate relative to the rotating shaft 3 or the slide rail 6. There is one slide rail 6 and one lead screw pair 8, corresponding to one cutter shaft 4. When there are two cutter shafts 4, the lead screws in the two lead screw pairs 8 are left and right rotating lead screws, so that the two cutter shafts 4 can move relative to or in opposite directions with the corresponding sliders 7. When there are three or more cutter shafts 4, they are sequentially mounted on the rotating shaft 3. Each cutter shaft 4 is provided with a slider 7 and a lead screw pair 8, so that each cutter shaft 4 can move independently.

[0036] In this embodiment, there are two cutter shafts 4, which are located at the two ends of the rotating shaft 3, and the rotating shaft 3 is equivalent to connecting the two cutter shafts 4.

[0037] The outer circumference of the cutter shaft 4 is provided with a grooved knife 5 along the axial direction. The paperboard is driven between the cutter shaft 4 and the roller 2. The grooved knife 5 grooves the paperboard as the cutter shaft 4 rotates. Multiple cutter shafts 4 can be synchronously rotated through a rotating shaft 3, and the structure is very compact and simple.

[0038] The outer wall of roller 2 is made of elastic material, such as soft rubber pad, so that the slotting knife 5 of the cutter shaft 4 will not cut the surface of roller 2 when slotting, and will not damage the slotting knife 5 itself, and can also stably convey the paperboard, or roller 2 is a rubber roller.

[0039] In this embodiment, the roller 2 is a long roller with a relatively long length, while the cutter shaft 4 is an axial roller 2 with a smaller length dimension. The length ratio of the cutter shaft 4 to the roller 2 is 1:4, and multiple cutter shafts 4 can be added as needed.

[0040] There can be two slide rails 6, and correspondingly, there are also two sliders 7 and two lead screw pairs 8, each corresponding to one of the two cutter shafts 4. The two slide rails 6 are arranged coaxially side by side on the bracket 1, and the lead screws in the lead screw pairs 8 are also arranged coaxially side by side. Since there are two lead screw pairs 8, each slider 7 individually corresponds to and engages with the lead screw pair 8. Therefore, the lead screw in the lead screw pair 8 can be a common single-start lead screw, allowing each slider 7 to be individually controlled through the corresponding slide rail 6 and lead screw pair 8. This enables the two cutter shafts 4 to move simultaneously or independently, providing great flexibility. In addition, the drive devices 9 that drive the lead screws, cutter shafts 4, and rollers 2 are all conventional belt and gear transmission structures, which will not be described in detail here.

[0041] In addition to the lead screw pair 8, the reciprocating movement of the cutter shaft 4 can also be achieved through mechanical transmission structures such as gears.

[0042] The cutter shaft 4 has an axial mounting groove 41 on its surface. The slotted cutter 5 includes a base 51 and a blade 52 located on the base 51. The base 51 is a plate-shaped structure with one side having an inwardly concave arc surface that conforms to the arc circumference of the cutter shaft 4. The blade 52 is mounted on the other side of the base 51. The base 51 is connected to the mounting groove 41 by fasteners such as bolts. That is, the fasteners pass through the mounting hole 53 and the mounting groove 41 in sequence and are fixed to the bottom of the mounting groove 41, so that the base 51 can be detachably fixed to the surface of the cutter shaft 4. The bottom shape of the base 51 is adapted to the outer wall shape of the cutter shaft 4, making the installation of the base 51 more stable.

[0043] Each cutter shaft 4 has multiple mounting slots 41, which are parallel to each other and circumferentially distributed on the outer peripheral wall of the cutter shaft 4. The number of slotted cutters 5 can be set one-to-one with the mounting slots 41, or one slotted cutter 5 can be fixed to two adjacent mounting slots 41. In short, there can be multiple slotted cutters 5, which are evenly distributed on the circumferential surface of the cutter shaft 4. When the cutter shaft 4 rolls, evenly spaced slots can be opened on the cardboard.

[0044] The blade 52 has a long strip structure and is integrally fixed to the base 51, meaning that the blade 52 can be installed and removed together with the base 51. The blade 52 has evenly distributed buffer blocks, such as sponges or rubber blocks, on both sides to press down on the cardboard after the blade 52 is raised after grooving, so as to prevent the cardboard from sticking to the blade 52.

[0045] The blade 322 has a long strip structure, and its cutting path can be a U-shape with one end open, a rectangle with one end open, or a straight strip, etc.

[0046] Another rotating shaft 3 is provided with an indentation knife 10. The indentation knife 10 is arranged along the axial direction of the rotating shaft 3. The indentation knife 10 can be detached or fixedly connected to the rotating shaft 3. That is, one rotating shaft 3 is respectively configured on each of the two rollers 2, and an indentation knife 10 is provided on one of the rotating shafts 3, so that the combination of rollers, rotating shafts and indentation knife can form a horizontal indentation group 13.

[0047] Another rotating shaft 3 is equipped with a cutter shaft 4 but without an indentation cutter 10. The roller 2, rotating shaft 3, cutter shaft 4 and grooving cutter 5 can be combined to form a horizontal grooving group 12. The horizontal indentation group 13 and the horizontal grooving group 12 can be arranged in parallel and freely combined, so that indentation and grooving can be performed separately and in front of each other as required.

[0048] Of course, the roller 2, rotating shaft 3, cutter shaft 4, indentation knife 10 and grooving knife 5 are combined to form a horizontal grooving and indentation group that performs horizontal indentation and horizontal grooving simultaneously. That is, the horizontal indentation group 13, the horizontal grooving group 12 and the horizontal grooving and indentation group can be freely combined in parallel to achieve flexible grooving and indentation.

[0049] It should be noted that since roller 2 and rotating shaft 3 are connected to the support 1 in parallel rotation, the positions of roller 2 and rotating shaft 3 on the support 1 can be adjusted independently, so that the relative axial distance between roller 2 and rotating shaft 3 can be adjusted, thereby realizing the adjustable distance between the grooving knife 5 and the creasing knife 10 relative to the corresponding roller 2, which is suitable for paper of different thicknesses.

[0050] Similarly, the grooving knife 5 or the indentation knife 10 can be adjusted relative to the corresponding rotating shaft 3. That is, when the grooving knife 5 is installed on the rotating shaft 3, it can be away from or close to the axis of the rotating shaft 3. The same applies to the indentation knife 10. This makes the distance between the grooving knife 5 and the roller 2, and the distance between the indentation knife 10 and the roller 2 adjustable. This is equivalent to fine-tuning the distance between the roller 2 and the rotating shaft 3.

[0051] When there are two or more indentation tools 10 on the rotating shaft 3, the indentation tools 10 can be distributed at equal intervals or at unequal intervals along the outer circumference of the rotating shaft 3; at the same time, adjacent two indentation tools 10 can also be staggered relative to each other along the axial direction of the rotating shaft 3, so that the relative distance between the indentation tools 10 can be adjusted.

[0052] When there are two or more slotted cutters 5 on the cutter shaft 4, the slotted cutters 5 can be distributed at equal intervals or at unequal intervals along the outer circumference of the cutter shaft 4; at the same time, adjacent slotted cutters 5 can also be staggered relative to each other along the axial direction of the cutter shaft 4, so that the relative distance between the slotted cutters 5 can be adjusted.

[0053] It should be noted that, due to the presence of the clearance groove 11, the cutter shaft 4 can reciprocate along the axis of the rotating shaft 3.

[0054] In addition, besides being made of elastic material, the outer wall of roller 2 can also be equipped with a lower knife holder to cooperate with the downward pressing of the groove knife 5 and the indentation knife 10.

[0055] The specific structures of the embossing tool 10 and the grooving tool 5 are conventional technologies available on the market and will not be described in detail here.

[0056] Each rotating shaft 3 is connected to a drive device 9 at one end. The drive device 9 is a motor or other drive component. The drive device 9 drives the rotating shaft 3 to rotate, which in turn drives all the cutter shafts 4 to rotate synchronously. There is no need for a transmission structure between the cutter shafts 4, and the structure is very compact and simple.

[0057] Furthermore, the bracket 1, as a structure for supporting or fixing the entire assembly, is not limited to the structure shown in Figure 1 for fixing the slide rail 6.

[0058] Example 2

[0059] The basic content is the same as in Embodiment 1, except that there can be one roller 2 and one corresponding rotating shaft 3. The rotating shaft 3 is equipped with a cutting shaft 4 and a creasing knife 10, that is, the cutting shaft 4 and the creasing knife 10 are integrated and installed on the same rotating shaft 3. When there are two cutting shafts 4, the two cutting shafts 4 are located at the two ends of the rotating shaft 3 respectively. Each cutting shaft 4 is equipped with a grooving knife 5. The grooving knife 5 has a clearance groove 11. The clearance groove 11 is located in the center of the blade 52. The clearance groove 11 passes through both the blade 52 and the base 51. The creasing knife 10 passes through the clearance groove 11 and is connected to the rotating shaft 3. The top of the creasing knife 10 is lower than the blade 52, that is, the cutting edge of the creasing knife 10 is hidden in the clearance groove 11. The creasing knife 10 is usually set one-to-one with the blade 52, so that when creasing and grooving are performed simultaneously, the grooving is performed first and then the creasing.

[0060] Regarding the two embodiments described above, the rotating shaft 3 that can simultaneously mount the tool shaft 4 and the indentation tool 10 is defined as rotating shaft one, the rotating shaft that can only mount the tool shaft 4 is defined as rotating shaft two, and the rotating shaft that can only mount the indentation tool 10 is defined as rotating shaft three. Structurally, they can be divided into two cases:

[0061] 1. Rotary shaft 1, rotary shaft 2 and rotary shaft 3 are all rotary shafts with the same structure. Rotary shaft 3 is provided with a mounting structure for mounting the tool shaft and the indentation tool, so that the rotary shaft 3 can be used to mount the tool shaft or the indentation tool alone, or to mount the tool shaft 4 and the indentation tool 10 at the same time. That is, the rotary shaft 3 is a universal type.

[0062] 2. Rotary shaft 1, rotary shaft 2 and rotary shaft 3 are rotary shafts 3 with different structures. Rotary shaft 1 is equipped with a mounting structure that can simultaneously install the tool shaft 4 and the indentation tool 10. Rotary shaft 2 is equipped with a mounting structure that can only install the tool shaft 4. Rotary shaft 3 is equipped with a mounting structure that can only install the indentation tool 10. That is, rotary shaft 3 is divided into three different structures.

[0063] The rotating shaft 3 in both of the above situations falls within the protection scope of this utility model.

[0064] The bracket serves as the support structure for the entire assembly. Rollers 2, rotating shafts 3, slide rails 6, and lead screw pairs 8 are all directly connected to the bracket, while the cutter shaft 2 is indirectly connected to the bracket through a transmission structure. The specific form will not be described in detail here.

[0065] Example 3

[0066] This utility model also provides a transverse slotting and creasing module, including the aforementioned transverse slotting and creasing assembly. Its basic content is the same as in Embodiments 1 and 2. The difference in this embodiment is that when two rotating shafts 3 are used, and each rotating shaft 3 is equipped with a creasing knife 10, the cardboard passes between the two rotating shafts 3. The two rotating shafts 3 rotate to cause the creasing knife 10 to creasing both sides of the cardboard. Each of the two rotating shafts 3 is equipped with a drive mechanism, which controls the corresponding rotating shaft 3 to rotate and lift. The cardboard passes between the two rotating shafts 3, and the two rotating shafts 3 rotate to cause the creasing knife on them to creasing both sides of the cardboard. Simultaneously, the lifting action of the rotating shafts 3 allows the two rotating shafts 3 to reciprocate radially, thereby adjusting the radial distance between the two rotating shafts 3. Ultimately, this enables the two rotating shafts 3 to creasing cardboard of different thicknesses.

[0067] In this embodiment, the drive mechanism includes a transmission structure 14 and a lifting structure 16.

[0068] In this embodiment, the transmission structure 14 is a gear set structure. One end of the rotating shaft 3 is connected to the driven wheel, and the output end of the first driving member 15 is connected to the driving wheel. The first driving member 15 drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate, thereby driving the rotating shaft 3 to rotate, so that the rotating shaft 3 can achieve indentation through rotation. Of course, the transmission structure 14 can also be a conventional structure such as a worm gear, a lead screw pair, etc., which will not be described in detail here.

[0069] In this embodiment, the lifting structure 16 includes a lead screw assembly 8 located on the support 1. The lifting end of the lead screw assembly is connected to the end of the rotating shaft 3, and the rotating end of the lead screw assembly 8 is connected to the second drive member 17 through a worm gear, so that the lead screw assembly 8 rotates and drives the rotating shaft 3 to move up and down. Lifting structures 16 are provided at both ends of the same rotating shaft 3, and the two lifting structures 16 work synchronously through a synchronizing rod 18, thereby realizing the synchronous lifting and lowering of the rotating shaft 3. In this way, the two rotating shafts 3 can rotate while moving relatively closer and further apart, which not only realizes the creasing work, but also can be applied to cardboard of different thicknesses.

[0070] It should be noted that a support plate 19 is provided between the end of the rotating shaft 3 and the first driving member 15, that is, the end of the rotating shaft 3 and the first driving member 15 are both fixed on the support plate 19. The lifting end of the lifting structure 16 is connected to the support plate 19, so that the support plate 19 is lifted and lowered through the lifting end, thereby driving the first driving member 15 and the rotating shaft 3 to lift and lower simultaneously.

[0071] The lifting structure 16 can also adopt conventional structures such as gear and rack, belt drive, or worm gear, which will not be described in detail here.

[0072] Finally, several points should be noted: First, in the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation," "fixing," and "connection" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change. This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
