[0002] With the continuous improvement of consumers' requirements for product appearance experience, creative product packaging plays an increasingly important role in market competition. Especially in the fields of gifts, cultural creativity and high-end consumer goods, creative product packaging not only needs to have basic protection and transportation functions, but also can emphasize its unique shape, exquisite patterns and personalized structural design. Such creative packaging puts forward higher requirements on the cutting precision, edge quality and processing flexibility of packaging materials such as paperboard.

[0003] In the prior art, a digital cutting device with model Cricut Maker 3 is widely used in DIY, education, small-scale cultural creativity product development and other fields. The device has the advantages of simple operation, perfect software ecology, support for multiple materials and quick replacement of knife heads, etc. The product mainly cooperates with intelligent pressure adjustment and high-precision numerical control cutting, can complete the creative packaging of complex graphics, is especially suitable for small batch, personalized design and prototype manufacturing, and has high practical value in the field of creative product packaging design.

[0004] Although the above-mentioned product can cut various materials, it needs to rely on an adhesive cutting pad to fix the materials, lacks a positive pressing mechanism for the materials, and has insufficient processing stability for thick or easily warped paperboard, and has no real-time pressure feedback and mechanical linkage control, so it is difficult to meet the needs of high-precision and repetitive production. Therefore, it is necessary to propose a cutting device for creative product packaging design that can improve accuracy and adaptability. SUMMARY

[0005] To solve the above problems, the present application provides a cutting device for creative product packaging design, which is used to drive the knife head to reciprocate by the vertical sliding plate, and the transmission mechanism pushes the pressing plate to fix the material, improving the accuracy of material cutting. The buffer mechanism at the bottom of the pressing plate is combined with the supply of the telescopic mechanism to output flexible downward pressure, adapt to different materials, and improve the diversification of packaging design.

[0006] In order to achieve the above purpose, the technical scheme of the present application is as follows: a cutting device for creative product packaging design, comprising a rack, a driving shaft is rotatably connected to the inner wall of the rack, and a driving mechanism for driving the driving shaft to rotate is arranged on the rack; a vertical sliding plate is slidably connected to the inner wall of the rack, and a plurality of knife heads are detachably connected to the bottom of the vertical sliding plate; a vertical sliding mechanism for driving the vertical sliding plate to reciprocate is arranged on the rack; the driving mechanism is used to drive the vertical sliding mechanism to run synchronously, so as to drive the knife head to cut.

[0007] The vertical sliding plate is provided with a pressing plate, a driving shaft is provided with a transmission mechanism for driving the pressing plate to press down, the transmission mechanism is provided with an extension mechanism for driving the pressing plate to press down again, the vertical sliding mechanism is used for driving the extension mechanism to operate synchronously to form a pressing force on the pressing plate, the bottom of the pressing plate is provided with a buffer mechanism for providing a flexible pressing force, the extension mechanism is used for providing a power source for the buffer mechanism, and the vertical sliding plate is further provided with a quick replacement mechanism for replacing the tool bit.

[0008] The technical principle of the above scheme is as follows:

[0009] After the driving mechanism is started, the driving shaft drives the vertical sliding plate to reciprocate through the vertical sliding mechanism, so that the tool bit completes the cutting operation, and the transmission mechanism pushes the pressing plate to press down the fixed material. At the same time, the vertical sliding mechanism drives the extension mechanism to press the pressing plate again, and the extension mechanism provides power for the buffer mechanism to output a flexible pressing force of the pressing plate. The quick replacement mechanism supports quick replacement of the tool bit to adapt to the cutting demand of different creative packaging, and the whole machine realizes the cooperative operation of cutting, pressing and tool replacement through the mechanical linkage of multiple mechanisms, so as to improve the cutting efficiency.

[0010] The above scheme has the following beneficial effects:

[0011] 1. According to the scheme, the vertical sliding plate drives the tool bit to reciprocate, the transmission mechanism pushes the pressing plate to fix the material, and the vertical sliding mechanism drives the extension mechanism to press the pressing plate again, so as to ensure that the material remains stable during the cutting process. The synchronous design can reduce the material displacement problem caused by the separate control of cutting and pressing in the traditional device, improve the cutting precision of the material, and adapt to the cutting demand of the creative packaging material precision. At the same time, the linkage of multiple mechanisms driven by a single power source simplifies the operation process, and the time sequence of cutting and pressing does not need to be adjusted frequently by manual operation, so as to reduce the operation complexity and make the batch production of creative packaging more efficient.

[0012] 2. According to the scheme, the buffer mechanism at the bottom of the pressing plate combines with the supply of the extension mechanism to output a flexible pressing force.

[0039] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The following detailed description illustrates the specific implementation method:

[0041] The basic implementation examples are as follows: Figures 1-5 As shown: A cutting device for creative product packaging design includes a frame 1, with a drive shaft 2 rotatably fitted on the inner wall of the frame 1. In this embodiment, the frame 1 includes a base plate and two fixed plates, both of which are symmetrically and integrally formed on the top of the base plate. The frame 1 is provided with a drive mechanism for driving the drive shaft 2 to rotate. A vertical slide plate 3 is slidably fitted on the inner wall of the frame 1. In this embodiment, the sliding fit between the vertical slide plate 3 and the fixed plates can provide guidance for it, so that the vertical slide plate 3 maintains a stable moving trajectory. Several cutter heads 4 are detachably connected to the bottom of the vertical slide plate 3. The frame 1 is provided with a vertical sliding mechanism for driving the vertical slide plate 3 to reciprocate. The drive mechanism is used to drive the vertical sliding mechanism to run synchronously, so as to drive the cutter heads 4 to cut.

[0042] The drive mechanism includes a controller and a drive component 5. In this embodiment, the controller is a PLC controller and the drive component 5 is a motor. The controller and the drive component 5 are electrically connected, and the drive component 5 is bolted to the outer wall of the frame 1. The output shaft of the drive component 5 passes through the frame 1, and the output shaft of the drive component 5 is coaxial with the drive shaft 2 and fixedly connected by a coupling.

[0043] The vertical sliding mechanism includes cams 6 keyed to both ends of the drive shaft 2, and push rods 8 screwed to both sides of the top of the vertical slide plate 3. The top of each push rod 8 contacts the outer wall of the cam 6. Tension springs 9 are screwed to the outer wall of each push rod 8, and the end of each tension spring 9 away from the push rod 8 is screwed to the inner wall of the frame 1.

[0044] Specifically, when the driving shaft 2 rotates under the drive of the driving part 5, the cam 6 fixed to both ends thereof rotates with the shaft, the top rod 8 is pushed downward by the cam 6 contour to drive the vertical sliding plate 3 and the cutter head 4 mounted at the bottom thereof to complete the downward cutting action, at this time, the tension spring 9 is stretched to store energy. When the cam 6 passes through the highest point and enters the return phase, the stretched tension spring 9 releases energy to drive the vertical sliding plate 3 and the cutter head 4 to quickly return to the initial position, completing a cutting cycle; through the synchronous operation of the driving part 5 and the vertical sliding cam 6, the above-mentioned action is cyclically repeated to realize continuous cutting.

[0045] In combination Figure 2 As shown, the embodiment further comprises a pressing plate 7, the driving shaft 2 is provided with a transmission mechanism for driving the pressing plate 7 to press downward; the transmission mechanism is provided with a telescopic mechanism for driving the pressing plate 7 to press downward again; the vertical sliding mechanism is used to drive the telescopic mechanism to operate synchronously to form a pressing force on the pressing plate 7; the bottom of the pressing plate 7 is provided with a buffer mechanism for providing a flexible pressing force; the telescopic mechanism is used to provide a power source for the buffer mechanism; the vertical sliding plate 3 is further provided with a quick-change mechanism for replacing the cutter head 4.

[0046] The transmission mechanism comprises two eccentric wheels 12 connected to the driving shaft 2, the two eccentric wheels 12 are symmetrically arranged on both sides of the driving shaft 2, and the outer walls of the eccentric wheels 12 are both provided with rotating rings 10; the connecting pieces at the bottom of the rotating rings 10 are all screw-fixedly connected with the pressing plate 7. In some preferred embodiments, a limiting rod can be installed on the outer wall of the eccentric wheel 12 to ensure that the rotating ring 10 is always located on the outer wall of the eccentric wheel 12; the pressing plate 7 is slidably connected with the inner wall of the rack 1 to make the pressing plate 7 keep a linear motion track and keep stable during the movement; the eccentric wheel 12 can be integrated on a transmission shaft with a separate power component to make the pressing action and the cutting synchronous and step-by-step.

[0047] In combination Figure 4 As shown, the connecting piece comprises a plurality of connecting plates 14, a plurality of cavities 11 and a plurality of output rods 13, the connecting plates 14 are all screw-fixedly connected with the outer wall of the rotating ring 10; the cavities 11 are all screw-fixedly connected with the bottom of the connecting plate 14, and the inner side walls of the cavities 11 are all slidably matched with the piston plates 15; the output rods 13 are all fixedly bonded with the bottom of the piston plate 15, and the bottom ends of the output rods 13 are all screw-fixedly connected with the pressing plate 7; the telescopic mechanism is used to transmit gas inside the cavity 11.

[0048] In combination Figure 5As shown, the telescopic mechanism includes transmission cylinders 16 fixedly connected to the inner wall of the frame 1 by screws, and transmission rods 17 fixedly connected to the outer wall of the top rod 8 by screws; the ends of the transmission rods 17 away from the top rod 8 are fixedly bonded with movable plates 18, and the movable plates 18 are in sliding fit with the inner side wall of the transmission cylinder 16. The bottom of each transmission cylinder 16 is communicated with an input pipe and an output pipe, and the connection between the input pipe and the output pipe and the transmission cylinder 16 is provided with a one-way valve; in this embodiment, the one-way valve is used to make the external gas flow into the input pipe and then flow out through the output pipe; the input pipe is in communication with the outside of the transmission cylinder 16, and the end of the output pipe away from the transmission cylinder 16 is in communication with the inside of the cavity 11.

[0049] Specifically, after the controller starts the driving member 5, the driving shaft 2 synchronously drives the cam 6 to rotate; the cam 6 pushes the top rod 8 downward, drives the vertical slide plate 3 and the bottom cutter head 4 to slide downward along the frame 1 to complete the cutting action; at the same time, the eccentric wheel 12 on the driving shaft 2 rotates synchronously, and the eccentric distance of the eccentric wheel 12 changes constantly when it rotates, so that the external rotating ring 10 drives the connecting member as a whole to move downward, and the pressing plate 7 first contacts the material surface to realize the initial pressing. With the downward movement of the vertical slide plate 3, the transmission rod 17 fixed to the top rod 8 pushes the movable plate 18 to move downward in the transmission cylinder 16, compresses the gas in the transmission cylinder 16 and inputs it into the cavity 11 through the output pipe, pushes the piston plate 15 to generate additional downward pressure, and makes the pressing plate 7 realize secondary pressing, so that the pressing action occurs before the cutting action.

[0050] When the vertical slide plate 3 rises, the transmission rod 17 rises with it, the movable plate 18 generates negative pressure in the transmission cylinder 16, and the gas is sucked in through the input pipe to prepare for the next pressing, and the gas in the cavity 11 maintains the continuous pressing state of the pressing plate 7 through the slow-release mechanism until the eccentric wheel 12 rotates to the lifting section to drive the pressing plate 7 to rise as a whole. During the whole movement process, the cutting action and the pressing action are mechanically synchronized through the same driving shaft 2, the downward pressure of the pressing plate 7 is proportional to the cutting action, and the stable pressing state of the material during the cutting process is ensured.

[0051] The buffer mechanism includes a plurality of air bags 19 fixedly bonded to the bottom of the pressing plate 7, the air bags 19 are in communication with each other, and the communication part between adjacent air bags 19 is provided with a first electromagnetic valve; the top of the cavity 11 is communicated with a delivery pipe, the end of the delivery pipe away from the cavity 11 is communicated with the air bags 19, and the delivery pipe is further provided with a second electromagnetic valve on the communication path with the cavity 11; the first electromagnetic valve and the second electromagnetic valve are electrically connected with the controller. In this embodiment, a part of gas is preferentially filled in the air bags 19, and the inside remains sealed during the downward pressing process of the connecting plate 14 and the cavity 11, so that the connecting plate 14 can stably drive the cavity 11 to press downward.

[0052] The quick-change mechanism includes an electromagnetic block 20 fixedly connected to the bottom of the vertical sliding plate 3 by a screw, and the electromagnetic block 20 is electrically connected to the controller; the top of each cutter head 4 is fixedly connected with a magnetic block by a screw, and the magnetic blocks are magnetically matched with the electromagnetic block 20.

[0053] Specifically, when the driving shaft 2 rotates, the vertical sliding plate 3 and the cutter head 4 are driven by the cam 6 to perform a cutting action, and the pressing plate 7 is driven downward by the eccentric wheel 12. During the downward pressing process, the synchronous transmission in the transmission cylinder 16 is transmitted to the inside of the air bag 19; each air bag 19 controls the opening and closing of the first electromagnetic valve or the second electromagnetic valve according to the material profile or material characteristics, so as to produce self-adaptive deformation and form uniform flexible pressing force. In this embodiment, the first electromagnetic valve is adjusted according to the preset parameters to ensure the pressure balance between the connected air bags 19; at the same time, the second electromagnetic valve is controlled to adjust the gas transmission from the cavity 11 to the air bag 19, so as to realize self-adaptive control of the pressing force.

[0054] When it is necessary to replace the cutter head 4, the controller controls the electromagnetic block 20 to be powered off and demagnetized, so as to release the adsorption relationship with the magnetic block of the current cutter head 4; when the new cutter head 4 is replaced, the electromagnetic block 20 is powered on to generate a magnetic force, and the magnetic block of the new cutter head 4 is firmly connected. The whole working process realizes the cooperation of multiple actions under the drive of a single power source, and realizes the quick and safe tool replacement, which embodies the advantages of mechatronic control.

[0055] In this embodiment, the functions of cutting and pressing are cleverly linked by a single driving shaft 2. While the cam 6 drives the vertical sliding plate 3 to complete precise cutting, the eccentric wheel 12 drives the pressing mechanism to realize primary pressing, and the transmission rod 17 moving synchronously with the vertical sliding plate 3 further provides secondary downward pressure for the pressing plate 7 through the gas transmission of the transmission cylinder 16; in combination with the intelligent pressure regulating design of the bottom interconnected air bags 19, the self-adaptive pressing effect of rigidity and flexibility is realized, and the electromagnetic quick-change cutter head 4 mechanism is used together to form a complete working process of high-efficiency cooperation and intelligent regulation and control, which guarantees the cutting precision and improves the production efficiency and product quality stability.

[0056] In another embodiment, the bottom of each air bag 19 is fixedly bonded with a pressure sensor (not shown in the figure), and the air bag 19 is also communicated with an exhaust valve; the controller is used to acquire the pressure information sent by the pressure sensor, and to control the operation of the first electromagnetic valve, the second electromagnetic valve and the exhaust valve based on the pressure information.

[0057] The specific implementation process is as follows: when the driving shaft 2 drives the cam 6 mechanism to operate, the vertical sliding plate 3 and the cutter head 4 perform the cutting action, and the pressing plate 7 is in contact with the material surface under the driving of the transmission mechanism. At this time, the pressure sensor at the bottom of the air bag 19 monitors the pressing force in real time, and transmits the pressure information to the controller. The controller dynamically adjusts the opening and closing of the first electromagnetic valve, the second electromagnetic valve and the exhaust valve according to the comparison between the preset pressure range and the real-time pressure information. When the pressure is insufficient, the controller opens the second electromagnetic valve to supplement the air bag 19 with gas; when the pressure is too high, the exhaust valve is opened to release part of the gas.

[0058] During the whole movement process, the cutting action and the adaptive pressing action are mechanically synchronized through the same driving shaft 2, and the air pressure regulation is accurately closed-loop controlled according to the real-time feedback of the pressing force, which not only ensures the stable pressing of the material during the cutting process, but also avoids the damage of the material caused by excessive pressure, and realizes the intelligent pressing effect of the combination of rigidity and flexibility.

[0059] In still another embodiment, the device is combined with a cutting device, and the cutting device is arranged on the pressing plate. Figure 5 As shown, the top rod 8 and the connection part of the vertical sliding plate 3 are both provided with gas springs 21, the gas springs 21 are screw-fixedly connected to the bottom of the top rod 8, and the output ends of the gas springs 21 are screw-fixedly connected with the vertical sliding plate 3; the controller is used for controlling the operation of the gas springs 21 based on the pressure information.

[0060] The specific implementation process is as follows: when the device starts to operate, the driving shaft 2 drives the cam 6 to rotate and push the top rod 8 to press down, at this time, the gas spring 21 descends synchronously with the top rod 8. During the cutting process, the controller obtains the pressure data detected by the pressure sensor in real time, and dynamically adjusts the supporting force of the corresponding position gas spring 21 when it is identified that the uneven thickness of the material or the irregular curved surface causes the local pressure to be abnormal. If the pressure is insufficient, the rigidity of the gas spring 21 is increased to increase the local pressing force, and if the pressure is too large, the pressure of the gas spring 21 is reduced to form a buffer protection. Through this dynamic adjustment, the vertical sliding plate 3 can adapt to the ups and downs of different material surfaces while completing accurate cutting, and the uniformity of the cutting depth is maintained.

[0061] Obviously, the above embodiments are only examples for clearly illustrating, and not limit the implementation. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
