[0002] In the production and transmission of sheet materials, it is necessary to die-cut non-compliant parts in the sheet materials. For example, the joint parts that bond adjacent sheet units are cut and removed.

[0003] Among them, the existing die-cutting is carried out in an unfixed manner, which will produce defective products in the overlapping parts of multiple layers of materials, resulting in cost waste. Summary of the Utility Model

[0004] In view of the above problems, the present application provides a die-cutting device and a conveying device, which can solve the problems.

[0005] To solve the above technical problems, a technical solution adopted by the present application is to provide a die-cutting device, which includes: a cutting mechanism arranged corresponding to a transmission device of a sheet material; wherein, the sheet material includes at least two sheet units, and an adhesive material is provided at the adjacent position of each adjacent two of the sheet units; a detection sensor connected to the cutting mechanism and arranged facing the sheet material transmitted by the transmission device, and the detection sensor is configured to detect the adhesive material to generate a trigger signal; wherein, the cutting mechanism is configured to receive the trigger signal sent by the detection sensor to cut and remove the adhesive material on the adjacent two sheet units.

[0006] As described above, according to the different characteristics of the adhesive material and each sheet unit, a detection sensor capable of identifying the difference between the adhesive material and each sheet unit is selected to detect and identify the adhesive material, so as to trigger the cutting mechanism to cut and remove the adhesive material on the adjacent two sheet units. By integrating the detection and cutting functions, the die-cutting device can automatically and accurately perform positioning and cutting operations on the sheet material containing the adhesive material, thereby realizing an efficient and high-precision automated production process and ensuring the yield and consistency of each sheet unit after cutting.

[0007] In a possible implementation, the cutting mechanism includes a first cutting component and a second cutting component. The first cutting component and the second cutting component are sequentially arranged at intervals in a set direction corresponding to the conveying device. The detection sensor is connected to a side of the first cutting component facing away from the second cutting component. Wherein, the set direction is the conveying direction of the sheet material. The first cutting component is configured to receive a first trigger signal sent by the detection sensor to cut one of two adjacent sheet units. The second cutting component is configured to receive a second trigger signal sent by the detection sensor to cut the other of two adjacent sheet units.

[0008] As described above, by arranging the corresponding first cutting component and the second cutting component at intervals, it is ensured that two adjacent sheet units can be accurately cut and separated, so as to realize a double cutting operation during the continuous conveying process of the sheet material, thereby effectively removing the adhesive material.

[0009] In a possible implementation, the detection sensor includes a first sensor and a second sensor. The first sensor is connected to a side of the first cutting component facing away from the second cutting component. The first sensor is configured to detect the adhesive material to generate the first trigger signal. The second sensor is connected to a side of the second cutting component facing the first cutting component. The second sensor is configured to detect the adhesive material to generate the second trigger signal.

[0010] As described above, through the first sensor and the second sensor respectively arranged corresponding to the first cutting component and the second cutting component, it is convenient to perform precise and synchronous double cutting operations on the adhesive material on the sheet material during the continuous conveying process of the sheet material.

[0011] In a possible implementation, the first cutting component includes a first conveying roller and a first original knife. The first sensor and the first original knife are sequentially connected to the first conveying roller at intervals in the set direction. The second cutting component includes a second conveying roller and a second original knife. The second sensor and the second original knife are sequentially connected to the second conveying roller at intervals in the set direction.

[0012] As described above, the first conveying roller and the second conveying roller cooperate with the conveying device to realize the continuous conveying of the sheet material, and the first sensor and the second sensor are used to timely identify the adhesive material during the conveying process, so as to trigger the first original knife and the second original knife to perform corresponding cutting operations immediately. Through the precise cooperation of two sensors and two sets of cutting mechanisms, accurate and synchronous double-sided cutting of the continuous material with the adhesive material part is ensured.

[0013] In a possible implementation, the first cutting assembly further includes a first base and a first linkage roller. The first linkage roller is connected to the first base and is disposed on opposite sides of the sheet material conveyed by the conveying device corresponding to the first conveying roller; the second cutting assembly further includes a second base and a second linkage roller. The second linkage roller is connected to the second base and is disposed on opposite sides of the sheet material conveyed by the conveying device corresponding to the second conveying roller.

[0014] As described above, when the sheet material conveyed by the conveying device passes through the first conveying roller and the second conveying roller, it can be effectively supported and guided from the other side by the acting force of the first linkage roller and the second linkage roller, thereby ensuring the stable conveyance of the material during the cutting process and reducing the possibility of deviation or deformation.

[0015] In a possible implementation, the cutting mechanism further includes an extraction assembly. The extraction assembly is disposed in the set direction of the second cutting assembly corresponding to the conveying device. The extraction assembly is configured to receive the third trigger signal sent by the detection sensor to drive the adhesive material removed from two adjacent sheet units away from the sheet units.

[0016] As described above, when the detection sensor sends the third trigger signal, the extraction assembly can quickly respond and perform an action, accurately remove the adhesive material successfully cut from between two adjacent sheet units, and effectively transfer it away from the sheet units, ensuring the cleanliness of the processing area after cutting and the smooth progress of subsequent processes.

[0017] In a possible implementation, the extraction assembly includes an extraction roller, a first auxiliary roller, and a second auxiliary roller. The first auxiliary roller, the extraction roller, and the second auxiliary roller are sequentially arranged at intervals in the set direction corresponding to the conveying device; wherein, the first auxiliary roller, the extraction roller, and the second auxiliary roller are configured to tension and convey an adhesive tape, and the extraction roller is configured to receive the third trigger signal sent by the detection sensor to adhere the adhesive material removed from two adjacent sheet units and drive the adhesive material to move close to the second auxiliary roller.

[0018] As described above, the first auxiliary roller, the extraction roller, and the second auxiliary roller work together to tension and convey the adhesive tape. During this process, they ensure the stable operation of the tape. When the detection sensor sends the third trigger signal, the extraction roller is configured to be able to respond immediately, effectively adhere the adhesive material cut from two adjacent sheet units using the adhesive tape, and drive the peeled adhesive material to move towards the second auxiliary roller through its own rotational power, thereby realizing the effective collection and cleaning of the adhesive material after cutting.

[0019] In a possible implementation, the extraction assembly further includes a third base and a third linkage roller, wherein the third linkage roller is connected to the third base and is disposed on opposite sides of the sheet material transmitted by the transmission device corresponding to the extraction roller.

[0020] As mentioned above, in the process of the adhesive material being cut from two adjacent sheet units and being adhered and transferred through the extraction roller, the third linkage roller can provide necessary auxiliary support and guiding functions to ensure the stability and accuracy of the entire extraction process, and effectively prevent the material from being offset or wrinkled during movement, thereby optimizing the working efficiency and effect of the entire die-cutting device.

[0021] In a possible implementation, the detection sensor is a color mark sensor, and the grayscale of the adhesive material is different from the grayscale of the sheet unit.

[0022] As mentioned above, according to the different grayscales of the adhesive material and each sheet unit, a color sensor with grayscale recognition function is selected, so that when the continuous sheet material passes through the transmission device, the color sensor will monitor and capture the grayscale changes of the adhesive material position in real time, so as to accurately guide the cutting mechanism to cut at the position of the adhesive material, ensuring that the two adjacent sheet units are effectively separated, while avoiding the situation of miscutting the normal sheet unit. In addition, with the asynchronous die-cutting waste discharge function, it can further realize the efficient removal and collection of adhesive material waste generated after cutting, ensuring that the entire die-cutting process is smooth and efficient and the product quality is stable.

[0023] In a possible embodiment, the cutting mechanism includes a cutting component and a driving component, wherein the driving component is connected to the cutting component and is communicatively connected to the detection sensor, and the driving component is configured to receive the trigger signal sent by the detection sensor to drive the cutting component to cut and remove the adhesive material on two adjacent sheet units.

[0024] As mentioned above, the cutting component is responsible for performing the physical cutting action and separating the adhesive material precisely at the location where the sheet unit meets the adhesive material. The drive component plays the role of the control center. It is not only directly connected to the cutting component to provide the necessary power and precise motion control, but also linked with the color mark sensor through the communication line.

[0025] In a possible embodiment, the cutting mechanism also includes a controller, which is communicatively connected to the detection sensor and the drive assembly and is used to communicate with the transmission device. The controller is configured to receive the trigger signal sent by the detection sensor to adjust the working state of the drive assembly and the transmission device.

[0026] As mentioned above, by setting up a controller, the working state of the driving component can be accurately adjusted according to the received trigger signal, such as starting, stopping or adjusting its running speed and cutting position, to ensure that the cutting component accurately separates the adhesive material between two adjacent sheet units. At the same time, the controller can also control the running state of the transmission device in a linked manner, such as pausing or resuming the transmission process in a timely manner to facilitate the smooth progress of the cutting action, thereby achieving highly automated and precise operations in the entire die-cutting process.

[0027] In order to solve the above-mentioned technical problems, another technical solution adopted in the present application is to provide a conveying device, which includes a conveying device and a die-cutting device, the die-cutting device includes a cutting mechanism and a detection sensor, the conveying device is used to convey sheet materials, and the cutting mechanism is arranged corresponding to the conveying device; wherein, the die-cutting device is a die-cutting device as described in any one of the above items.

[0028] As mentioned above, by arranging the unloading roller and the receiving roller on opposite sides of the die-cutting device, a complete material input and output system is formed, which can realize automated assembly line operation from unloading to cutting and then to receiving, and significantly improve production efficiency and product quality.

[0029] In a possible embodiment, the transmission device also includes a feed roller and a receiving roller, and the feed roller and the receiving roller are arranged on opposite sides of the die-cutting device, the feed roller is configured to transmit the rolled sheet material in sheet form toward the die-cutting device, and the receiving roller is configured to transmit the sheet unit obtained by cutting the sheet material by the die-cutting device.

[0030] As mentioned above, the entire process from unloading to cutting and then to collecting has realized automated assembly line operation, which has significantly improved production efficiency and product quality.

[0031] In a possible implementation, the transmission device further includes a third transmission roller, which is disposed between the unwinding roller and the receiving roller and is spaced apart from the die-cutting device, and is configured to transmit the sheet material.

[0032] As mentioned above, the sheet material released and initially flattened by the discharge roller will first pass through the third transmission roller for secondary positioning and tension transmission, ensuring that the material has an ideal flatness and a stable speed before entering the die-cutting device, thereby improving the cutting accuracy and efficiency.

[0033] In a possible implementation, the transmission device further includes a conveyor belt, the conveyor belt is connected to the die-cutting device, and the conveyor belt is configured to transmit through the die-cutting device and carry the sheet material transmitted in sheet form.

[0034] As described above, by setting the conveyor belt to carry the sheet material transmitted in the form of a sheet, the sheet material is kept flat and orderly on the conveyor belt, ensuring accurate alignment with the cutting position when entering the die-cutting area. After cutting is completed, the sheets that have been separated into independent units will continue to be smoothly carried away from the die-cutting device by the conveyor belt and finally sent to the receiving roller for collection and sorting, thus forming an efficient and continuous automated production process.

[0047] Currently, in the production and transmission of sheet materials, in order to ensure product quality and production efficiency, it is necessary to accurately perform die-cutting on non-standard parts therein. For example, the joint parts connected by adhesive materials between adjacent sheet units are removed.

[0048] Traditional die-cutting refers to a cutting process in the post-processing of printed products. The die-cutting process can cut printed products or other paper products into die-cutting plates according to pre-designed graphics, so that the shape of the printed products is no longer limited to straight edges and right angles. In traditional die-cutting production, die-cutting knives are combined into a die-cutting plate according to the patterns required by product design. Under the action of pressure, the printed products or other plate-shaped blanks are rolled and cut into the required shapes or cut marks.

[0049] However, when the traditional die-cutting method adopts an unfixed cutting mode, it is often difficult to accurately judge the joint position. Especially in the area where multiple layers of materials are stacked, it is easy to cause mis-cutting or incomplete cutting, resulting in defective products and wasting costs.

[0050] Based on the above considerations, in order to solve the technical problems in the prior art that the die-cutting device is prone to mis-cutting or incomplete cutting, resulting in defective products and wasting costs, the present application proposes a die-cutting device. The die-cutting device can select a detection sensor with the ability to identify the difference between the adhesive material and each sheet unit according to the different characteristics of the adhesive material and each sheet unit, accurately identify and locate the adhesive material, so as to trigger the cutting mechanism to cut and remove the adhesive material between two adjacent sheet units. By integrating the detection and cutting functions, the die-cutting device is further controlled to achieve precise positioning cutting, avoid cost waste caused by mis-cutting, and thus realize an efficient and high-precision automated production process, and ensure the yield and consistency of each sheet unit after cutting.

[0051] For example, as Figure 1Schematic structural diagram of a die-cutting device according to some embodiments. In some embodiments, the die-cutting device 1 includes a cutting mechanism 10 and a detection sensor 20. The cutting mechanism 10 is arranged corresponding to a conveying device 100 of a sheet material 201. The sheet material 201 includes at least two sheet units, and an adhesive material (not shown in the figure) is provided at the adjacent position of every two adjacent sheet units. The detection sensor 20 is connected to the cutting mechanism 10, is arranged facing the sheet material 201 conveyed by the conveying device 100, and the detection sensor 20 is configured to detect the adhesive material to generate a trigger signal. Among them, the cutting mechanism 10 is configured to receive the trigger signal sent by the detection sensor 20 to cut and remove the adhesive material on two adjacent sheet units.

[0052] In some embodiments, the cutting mechanism 10 can be a mechanical component with a cutting function. It can be a mechanical component provided with a cutting knife, a die-cutting original knife, or other reasonable cutting knives. The mechanical structure of the cutting mechanism 10 can be set according to actual needs. The detection sensor 20 is a detection device with the ability to identify different characteristics between the adhesive material and each sheet unit. It can be a color mark sensor, a photosensitive sensor, an infrared sensor, or other reasonable sensors, and can be adjusted according to requirements. Among them, the cutting mechanism 10 is a key component that performs the actual cutting operation, and it is arranged at the corresponding position of the sheet material 201 transmission device 100. To facilitate cutting during the transmission process of the sheet material 201, the cutting mechanism 10 can be a conveying roller provided with a cutting knife or a die-cutting original knife, which is configured with the transmission device 100 to convey the sheet material 201 and perform positioning cutting during the transmission process. The transmission device 100 is used to carry and move the sheet material 201, and can have one or more of any reasonable mechanical mechanisms with a material conveying function such as conveying rollers, tension rollers, conveyor belts, etc., to ensure that the material passes through the working area where the cutting mechanism 10 is located smoothly and accurately according to the preset path. The sheet material 201 is a PET (Polyethyleneterephthalate) protective film or release paper, or other reasonable sheet materials 201. The sheet material 201 can be specifically placed in a roll shape and transmitted in a sheet form via the transmission device 100. The adhesive material is a masking paper or other adhesive sheet such as an adhesive layer, etc. The adhesive material is located between every two adjacent sheet units and plays a role of connection or temporary fixation, and may need to be removed in subsequent processes. The detection sensor 20 is connected to the cutting mechanism 10 and is arranged facing the sheet material 201 conveyed by the transmission device 100. The sensor has the ability to identify and locate the adhesive material. When the adhesive material is detected, it can generate a trigger signal. After the detection sensor 20 detects the adhesive material and generates a trigger signal, the signal will be sent to the cutting mechanism 10, so that the cutting mechanism 10 can accurately control its actions according to the received trigger signal, thereby cutting off the adhesive material between two adjacent sheet units.

[0053] Through the above method, according to the different characteristics of the adhesive material and each sheet unit, a detection sensor 20 with the ability to identify the difference between the adhesive material and each sheet unit is selected to detect and identify the adhesive material, so as to trigger the cutting mechanism 10 to cut off the adhesive material on two adjacent sheet units. By integrating the detection and cutting functions, the die-cutting device 1 can automatically and accurately perform positioning and cutting operations on the sheet material 201 containing the adhesive material, thereby realizing an efficient and high-precision automated production process and ensuring the yield and consistency of each sheet unit after cutting.

[0054] In some embodiments, the cutting mechanism 10 includes a first cutting component 11 and a second cutting component 12. The first cutting component 11 and the second cutting component 12 are sequentially arranged at intervals in a set direction corresponding to the conveying device 100. The detection sensor 20 is connected to the side of the first cutting component 11 facing away from the second cutting component 12. Wherein, the set direction is the conveying direction of the sheet material 201. The first cutting component 11 is configured to receive a first trigger signal sent by the detection sensor 20 to cut one of two adjacent sheet units, and the second cutting component 12 is configured to receive a second trigger signal sent by the detection sensor 20 to cut the other of two adjacent sheet units.

[0055] Wherein, the cutting mechanism 10 is composed of a first cutting component 11 and a second cutting component 12, and the two are arranged at intervals in sequence along the conveying device 100 in the direction of the transmission path of the set sheet material 201. In some embodiments, the number of detection sensors 20 is one, and the detection sensor 20 is installed on the side of the first cutting component 11 away from the second cutting component 12 and is connected thereto; in this set direction, when the sheet material 201 passes through, the detection sensor 20 responds to detecting the adhesive material and first sends a first trigger signal to the first cutting component 11 to cut one of two adjacent sheet units; subsequently, and specifically after a preset interval time, a second trigger signal is sent to the second cutting component 12 to cut the other unit of the same pair of adjacent sheet units; the preset interval time can be reasonably set according to the actual conveying speed of the sheet material 201 and the action response speeds of the detection sensor 20, the first cutting component 11, and the second cutting component 12. In some other embodiments, the number of detection sensors 20 can also be two, and the two detection sensors 20 are respectively installed on the first cutting component 11 and the second cutting component 12; in the set direction, when the sheet material 201 passes through, one of the detection sensors 20 responds to detecting the adhesive material and sends a first trigger signal to the first cutting component 11 to cut one of two adjacent sheet units; the other detection sensor 20 responds to detecting the adhesive material and sends a second trigger signal to the second cutting component 12 to cut the other unit of the same pair of adjacent sheet units.

[0056] In the above manner, it is ensured that two adjacent sheet units can be accurately cut and separated, so as to realize a double cutting operation during the continuous conveying process of the sheet material 201, thereby effectively removing the adhesive material.

[0057] In some embodiments, the detection sensor 20 includes a first sensor 21 and a second sensor 22. The first sensor 21 is connected to a side of the first cutting assembly 11 facing away from the second cutting assembly 12, and the first sensor 21 is configured to detect an adhesive material to generate a first trigger signal. The second sensor 22 is connected to a side of the second cutting assembly 12 facing the first cutting assembly 11, and the second sensor 22 is configured to detect an adhesive material to generate a second trigger signal.

[0058] Specifically, the detection sensor 20 actually consists of two independent sensor elements: the first sensor 21 and the second sensor 22. The first sensor 21 is installed on the side of the first cutting assembly 11 away from the second cutting assembly 12. Its main function is to detect the presence of the adhesive material on the sheet material 201 during transmission. Once the adhesive material is detected, the first sensor 21 generates and sends a first trigger signal to trigger the first cutting assembly 11 to perform cutting at an appropriate position. On the other hand, the second sensor 22 is arranged on the side of the second cutting assembly 12 facing the first cutting assembly 11. Its role is also to detect the position of the specific adhesive material on the passing sheet material 201. When the second sensor 22 detects the adhesive material, a second trigger signal is generated, which will guide the second cutting assembly 12 to perform cutting at the corresponding point, ensuring that two adjacent sheet units can be accurately separated to cut off the adhesive material.

[0059] In the above manner, it is convenient to perform precise and synchronous dual cutting operations on the adhesive material on the sheet material 201 during the continuous transmission of the sheet material 201.

[0060] In some embodiments, the first cutting assembly 11 includes a first transmission roller 111 and a first original knife 112. The first sensor 21 and the first original knife 112 are sequentially and spacedly connected to the first transmission roller 111 in a set direction; the second cutting assembly 12 includes a second transmission roller 121 and a second original knife 122. The second sensor 22 and the second original knife 122 are sequentially and spacedly connected to the second transmission roller 121 in a set direction.

[0061] Among them, the first cutting component 11 consists of a first transmission roller 111 and a first original knife 112. In some embodiments, the first transmission roller 111 is a cylindrical, elliptical cylindrical, or other reasonable-shaped rotatable cylindrical roller on the machine, which can be adjusted according to requirements. In some embodiments, the first original knife 112 is a cutting knife, a die-cutting original knife, or other reasonable cutting knives, which can be adjusted according to requirements. In the set direction, that is, the transmission direction of the sheet material 201, the first sensor 21 and the first original knife 112 are designed and installed on the first transmission roller 111, and the first original knife 112 is spaced in the set direction of the first sensor 21. Such a layout enables the first sensor 21 to detect the adhesive material before the first original knife 112 when the material to be cut passes through the first transmission roller 111, and issue the first trigger signal in a timely manner to precisely control the cutting action of the first original knife 112, ensuring that one of the adjacent sheet units is cut before the adhesive material is transported to the cutting position of the first original knife 112, so as to avoid part of the adhesive material remaining on the sheet unit due to cutting on the adhesive material. The distance between the first sensor 21 and the first original knife 112 and the response time of the first sensor 21 to issue the first trigger signal can be set according to the actual transmission speed of the sheet material 201 and the action response speed of the first original knife 112, and can be adjusted according to requirements. Similarly, the second cutting component 12 also has a similar configuration: including a second transmission roller 121 and a second original knife 122. In some embodiments, the second transmission roller 121 is a cylindrical, elliptical cylindrical, or other reasonable-shaped rotatable cylindrical roller on the machine, which can be adjusted according to requirements. The second transmission roller 121 can be the same as or different from the first transmission roller 111, which can be adjusted according to requirements. In some embodiments, the second original knife 122 is a cutting knife, a die-cutting original knife, or other reasonable cutting knives, which can be adjusted according to requirements. The second original knife 122 can be the same as or different from the first original knife 112, which can be adjusted according to requirements. The second sensor 22 and the second original knife 122 are orderly spaced and connected to the second transmission roller 121 in the set direction according to the same principle. In this way, during the process of the sheet material 201 flowing from the first cutting component 11 to the second cutting component 12, the second sensor 22 can timely identify the adhesive material and generate the second trigger signal, thereby triggering the second original knife 122 to perform the corresponding cutting operation, ensuring that after the adhesive material is all transported to the cutting position of the second original knife 122, the other of the adjacent sheet units is cut, so as to avoid part of the adhesive material remaining on the sheet unit due to cutting on the adhesive material. The distance between the second sensor 22 and the second original knife 122 and the response time of the second sensor 22 to issue the second trigger signal can be set according to the actual transmission speed of the sheet material 201 and the action response speed of the second original knife 122, and can be adjusted according to requirements.

[0062] In the above manner, the first transfer roller 111 and the second transfer roller 121 are used in cooperation with the transfer device 100 to realize the continuous transfer of the sheet material 201, and the first sensor 21 and the second sensor 22 are used to timely identify the adhesive material during the transfer process, so as to trigger the first original knife 112 and the second original knife 122 to perform corresponding cutting operations immediately. Through the precise cooperation of the two sensors and the two sets of cutting mechanisms 10, accurate and synchronous double-sided cutting of the continuous material with the adhesive material part is ensured.

[0063] In some embodiments, the first cutting assembly 11 further includes a first base 113 and a first linkage roller 114. The first linkage roller 114 is connected to the first base 113 and is disposed on opposite sides of the sheet material 201 corresponding to the first transfer roller 111 and transmitted through the transfer device 100; the second cutting assembly 12 further includes a second base 123 and a second linkage roller 124. The second linkage roller 124 is connected to the second base 123 and is disposed on opposite sides of the sheet material 201 corresponding to the second transfer roller 121 and transmitted through the transfer device 100.

[0064] Among them, in the first cutting assembly 11, in addition to the first transfer roller 111 and the first original knife 112, there are also a first base 113 and a first linkage roller 114. The first linkage roller 114 is firmly installed on the first base 113, and its position corresponds to both sides of the sheet material 201 corresponding to the first transfer roller 111. In some embodiments, the first linkage roller 114 is a cylindrical, ellipsoidal, or other reasonable-shaped rotatable cylindrical roller on the machine, which can be adjusted according to requirements. In some embodiments, the first base 113 is a rectangular mounting frame, a cylindrical bracket, or other reasonable mounting mechanical components, which can be adjusted according to requirements. The purpose of such a design is to ensure that the sheet material 201 conveyed by the conveying device 100 can be effectively supported and guided from the other side by the action of the first linkage roller 114 while passing through the first transfer roller 111, so as to ensure the stable conveyance of the material during the cutting process and reduce the possibility of deviation or deformation. Similarly, the second cutting assembly 12 also includes a second base 123 and a second linkage roller 124. The second linkage roller 124 is installed on the second base 123 and is in the same working plane as the second transfer roller 121, and also corresponds to both opposite sides of the sheet material 201 conveyed by the conveying device 100. In some embodiments, the second linkage roller 124 is a cylindrical, ellipsoidal, or other reasonable-shaped rotatable cylindrical roller on the machine, which can be adjusted according to requirements. The second linkage roller 124 can be the same as or different from the first linkage roller 114, and can be adjusted according to requirements. In some embodiments, the second base 123 is a rectangular mounting frame, a cylindrical bracket, or other reasonable mounting mechanical components, which can be adjusted according to requirements. The second base 123 can be the same as or different from the first base 113, and can be adjusted according to requirements. In this way, when the sheet material 201 transitions from the first cutting assembly 11 to the second cutting assembly 12, the second linkage roller 124 can also provide necessary auxiliary support and guidance for the material, enabling the entire continuous double-sided cutting process to proceed precisely and smoothly.

[0065] In the above manner, while the sheet material 201 passes through the first transfer roller 111 and the second transfer roller 121, it can be effectively supported and guided from the other side by the action of the first linkage roller 114 and the second linkage roller 124, so as to ensure the stable conveyance of the material during the cutting process and reduce the possibility of deviation or deformation.

[0066] In some embodiments, the cutting mechanism 10 further includes an extraction assembly 13. The extraction assembly 13 is disposed in the set direction of the second cutting assembly 12 corresponding to the conveying device 100. The extraction assembly 13 is configured to receive the third trigger signal sent by the detection sensor 20 to drive the adhesive material removed from two adjacent sheet units to move away from the sheet units.

[0067] Among them, the die-cutting device 1 is further equipped with an extraction component 13, which is installed in a set direction, that is, the conveying direction of the sheet material 201, according to the relative position relationship with the conveying device 100 and the second cutting component 12. In some embodiments, the extraction component 13 includes at least two conveying rollers that tension and convey the adhesive tape 202. The conveying rollers are cylindrical, elliptical, or other reasonable-shaped rotatable cylindrical rollers on the machine and can be adjusted according to requirements. In some other embodiments, the extraction component 13 includes a robotic arm, a grasping device, or other reasonable components and can be adjusted according to requirements. The main function of the extraction component 13 is that when the detection sensor 20 issues a third trigger signal, the extraction component 13 can quickly respond and perform an action to accurately remove the adhesive material successfully cut from between two adjacent sheet units and effectively transfer it away from the sheet unit, ensuring the cleanliness of the processed area after cutting and the smooth progress of subsequent processes.

[0068] In the above manner, the cleanliness of the processed area after cutting and the smooth progress of subsequent processes are ensured.

[0069] In some embodiments, the extraction component 13 includes an extraction roller 131, a first auxiliary roller 132, and a second auxiliary roller 133. The first auxiliary roller 132, the extraction roller 131, and the second auxiliary roller 133 are sequentially arranged at intervals in the set direction corresponding to the conveying device 100. Among them, the first auxiliary roller 132, the extraction roller 131, and the second auxiliary roller 133 are configured to tension and convey the adhesive tape 202, and the extraction roller 131 is configured to receive the third trigger signal sent by the detection sensor 20 to adhere to the adhesive material removed from two adjacent sheet units and drive the adhesive material to move close to the second auxiliary roller 133.

[0070] Among them, the extraction component 13 in the die-cutting device 1 is composed of an extraction roller 131, a first auxiliary roller 132, and a second auxiliary roller 133. These three rollers are arranged at intervals corresponding to the conveying device 100 in a preset direction sequence. In some embodiments, the extraction roller 131, the first auxiliary roller 132, and the second auxiliary roller 133 are cylindrical, elliptical, or other reasonably shaped rotatable cylindrical rollers on the machine, which can be adjusted according to requirements. The extraction roller 131, the first auxiliary roller 132, and the second auxiliary roller 133 can be different from each other, partially the same, or all the same, and can be adjusted according to requirements. Specifically, the first auxiliary roller 132, the extraction roller 131, and the second auxiliary roller 133 work together to tension and convey the adhesive tape 202. During this process, they ensure the stable operation of the tape. It is particularly worth mentioning the functional design of the extraction roller 131: when the detection sensor 20 issues a third trigger signal, the extraction roller 131 is configured to be able to respond immediately, effectively adhere the adhesive material cut from two adjacent sheet units to the adhesive tape 202, and drive these peeled adhesive materials to move in the direction of the second auxiliary roller 133 through its own rotational power, so as to move away from two adjacent sheet units.

[0071] Through the above method, the effective collection and cleaning of the cut adhesive material are realized.

[0072] In some embodiments, the extraction component 13 further includes a third base 134 and a third linkage roller 135. The third linkage roller 135 is connected to the third base 134 and is arranged on the opposite sides of the sheet material 201 corresponding to the extraction roller 131 and transmitted through the conveying device 100.

[0073] Among them, the extraction component 13 of the die-cutting device 1 is further improved, and a third base 134 and a third linkage roller 135 are added. The third linkage roller 135 is firmly installed on the third base 134 and maintains a corresponding relationship with the extraction roller 131. Its position is designed adjacent to both sides of the sheet material 201 conveyed through the conveying device 100. In some embodiments, the third linkage roller 135 is a cylindrical, elliptical, or other reasonably shaped rotatable cylindrical roller on the machine, which can be adjusted according to requirements. In some embodiments, the third base 134 is a rectangular mounting frame, a cylindrical bracket, or other reasonable mounting mechanical components, which can be adjusted according to requirements.

[0074] Through the above method, during the process of the adhesive material being cut from two adjacent sheet units and adhered and transferred by the extraction roller 131, the third linkage roller 135 can provide necessary auxiliary support and guiding functions, ensure the stability and accuracy of the entire extraction process, effectively prevent problems such as offset or wrinkles of the material during movement, and thus optimize the working efficiency and effect of the entire die-cutting device 1.

[0075] In some embodiments, the detection sensor 20 is a color mark sensor, and the gray scale of the bonding material is different from that of the sheet unit.

[0076] Among them, in the automated die-cutting system, the detection sensor 20 adopts color mark sensor technology. This kind of sensor can accurately identify and locate specific areas on the sheet material 201 according to the color or gray scale difference of the material. For this scenario, there is a significant difference in the gray scale between the bonding material and the sheet unit, which enables the color mark sensor to effectively distinguish between the two. When the continuous sheet material 201 passes through the transmission device 100, the color mark sensor will monitor the material surface in real time and identify the unique gray scale of the bonding material. Once the position of the bonding material is detected, the sensor will generate a corresponding trigger signal, which will be transmitted to the controller or the directly connected drive assembly, so as to command the cutting mechanism 10 to perform cutting at the accurate position, ensuring that the bonding material between adjacent sheet units is accurately removed. In some embodiments, in the images obtained under the same optical conditions, the gray scale value of the bonding material is greater than the gray scale values of each sheet unit. In some other embodiments, the gray scale value of the bonding material is 40 - 200 greater than the gray scale values of each sheet unit. In some other embodiments, the color of the bonding material is any reasonable color such as black, purple or dark green, and the color of each sheet unit is any reasonable color such as white, yellow or gray.

[0077] Through the above method, the product quality is improved, the generation of defective products and cost waste caused by mis-cutting are avoided, and the efficient automation of the production process is realized, improving the operation efficiency of the overall production line. In addition, in cooperation with the asynchronous die-cutting and waste discharging function, the efficient removal and collection of the bonding material waste generated after cutting can be further realized, ensuring the smooth, efficient and stable product quality of the whole die-cutting process.

[0078] In some embodiments, the cutting mechanism 10 includes a cutting component (not shown in the figure) and a drive component (not shown in the figure). The drive component is connected to the cutting component and communicatively connected to the detection sensor 20. The drive component is configured to receive the trigger signal sent by the detection sensor 20 to drive the cutting component to cut and remove the bonding material on adjacent two sheet units.

[0079] Among them, the cutting mechanism 10 is a precision system composed of two core components: a cutting component and a driving component. The cutting component is specifically responsible for performing the physical cutting action and precisely separating the bonding material at the position where it meets the sheet unit. The driving component, on the other hand, acts as the control center. It not only directly connects to the cutting component to provide the necessary power and precise motion control but also is linked with the color mark sensor through a communication line. In some embodiments, the driving component is a motor with an execution mechanical structure, a hydraulic press, or other reasonable mechanical components with driving force, which can be adjusted according to requirements. When the detection sensor 20 identifies the gray-scale difference between the bonding material and the sheet unit and sends out a trigger signal, the driving component will immediately respond to this signal instruction, accurately adjust the action parameters of the cutting component, such as speed, position, etc., and then start or adjust the cutting process to ensure that the bonding material between two adjacent sheet units is precisely cut and removed, thus ensuring the continuity of the production process and the consistency of product quality.

[0080] In the above manner, the cutting component is specifically responsible for performing the physical cutting action and precisely separating the bonding material at the position where it meets the sheet unit. The driving component, on the other hand, acts as the control center. It not only directly connects to the cutting component to provide the necessary power and precise motion control but also is linked with the color mark sensor through a communication line.

[0081] In some embodiments, the cutting mechanism 10 further includes a controller (not shown in the figure). The controller is communicatively connected to the detection sensor 20 and the driving component and is configured to be communicatively connected to the transmission device 100. The controller is configured to receive the trigger signal sent by the detection sensor 20 to adjust the working states of the driving component and the transmission device 100.

[0082] Among them, the cutting mechanism 10 further integrates a key component, the controller. The controller not only realizes communication connection with the detection sensor 20 and the driving component but also is responsible for the docking control with the transmission device 100. In some embodiments, the controller may include a signal processing chip, an MCU (Micro Control Unit) circuit, a CPU (Central Processing Unit), a single-chip microcomputer, a PLC (Programmable Logic Controller), a field programmable gate array, or other reasonable electronic devices with program and signal processing functions, which can be adjusted according to requirements. The color mark sensor generates a trigger signal based on the gray-scale difference between the bonding material and the sheet unit and makes judgments and responses accordingly.

[0083] In the above manner, the controller can accurately adjust the working state of the driving component according to the received trigger signal, such as starting, stopping or adjusting its running speed and cutting position, to ensure that the cutting component accurately separates the adhesive material between two adjacent sheet units. At the same time, the controller can also control the running state of the transmission device 100, such as pausing or resuming the transmission process in time to facilitate the smooth progress of the cutting action, thereby achieving highly automated and precise operation in the entire die-cutting process.

[0084] Finally, in a specific application scenario, for the existing die-cutting method, it is difficult to accurately determine the joint positions of each sheet unit. Especially in the area where multiple layers of materials are stacked, it is easy to cause mis-cutting or incomplete cutting, resulting in defective products and cost waste. The die-cutting device 1 of the present application includes a cutting mechanism 10 and a detection sensor 20. The cutting mechanism 10 includes a first cutting assembly 11, a second cutting assembly 12, an extraction assembly 13, a driving assembly, and a controller. The first cutting assembly 11 includes a first transfer roller 111, a first original knife 112, a first base 113, and a first linkage roller 114; the second cutting assembly 12 includes a second transfer roller 121, a second original knife 122, a second base 123, and a second linkage roller 124; the extraction assembly 13 includes an extraction roller 131, a first auxiliary roller 132, a second auxiliary roller 133, a third base 134, and a third linkage roller 135. The detection sensor 20 is a color mark sensor, and the gray scale of the adhesive material is different from that of the sheet unit. The detection sensor 20 includes a first sensor 21 and a second sensor 22. The first sensor 21 and the first original knife 112 are sequentially and spacedly connected to the first transfer roller 111 in a set direction; the second sensor 22 and the second original knife 122 are sequentially and spacedly connected to the second transfer roller 121 in a set direction; the first linkage roller 114 is connected to the first base 113 and is disposed on opposite sides of the sheet material 201 corresponding to the first transfer roller 111 and transmitted through the transmission device 100; the second linkage roller 124 is connected to the second base 123 and is disposed on opposite sides of the sheet material 201 corresponding to the second transfer roller 121 and transmitted through the transmission device 100; the first auxiliary roller 132, the extraction roller 131, and the second auxiliary roller 133 are sequentially and spacedly disposed corresponding to the transmission device 100 in a set direction; the third linkage roller 135 is connected to the third base 134 and is disposed on opposite sides of the sheet material 201 corresponding to the extraction roller 131 and transmitted through the transmission device 100. The driving assembly is connected to the first transfer roller 111, the first original knife 112, the first linkage roller 114, the second transfer roller 121, the second original knife 122, the second base 123, the second linkage roller 124, the extraction roller 131, the first auxiliary roller 132, the second auxiliary roller 133, and the third linkage roller 135, and is communicatively connected to the first sensor 21, the second sensor 22, and the controller.When the transmission device 100 conveys the sheet material 201 in a sheet form towards the die-cutting device 1, the first sensor 21 and the second sensor 22 detect the adhesive material on every two adjacent sheet units in the sheet material 201 in real time, so as to send a first trigger signal and a first trigger signal to the controller respectively when the adhesive material is detected, and send a third trigger signal to the controller via the first sensor 21 or the second sensor 22, so as to control the driving assembly to drive the first transmission roller 111 and the first linkage roller 114 to continuously convey the sheet material 201 by using the first trigger signal, and during the conveying process, drive the first original knife 112 to cut one of the two adjacent sheet units; control the driving assembly to drive the second transmission roller 121 and the second linkage roller 124 to continuously convey the sheet material 201 by using the second trigger signal, and during the conveying process, drive the second original knife 122 to cut the other of the two adjacent sheet units; control the driving assembly to drive the second transmission roller 121 and the second linkage roller 124 to continuously convey the sheet material 201 by using the second trigger signal, and during the conveying process, drive the second original knife 122 to cut the other of the two adjacent sheet units; control the driving assembly to drive the first auxiliary roller 132, the second auxiliary roller 133 and the third linkage roller 135 to tension and convey the adhesive tape 202 by using the third trigger signal, and drive the extraction roller 131 to drive the adhesive tape 202 to bond the adhesive material removed from the two adjacent sheet units, and drive the adhesive material to move close to the second auxiliary roller 133 for removal.

[0085] By the above method, according to the different characteristics of the adhesive material and each sheet unit, the first sensor 21 and the second sensor 22 capable of identifying the difference between the adhesive material and each sheet unit are selected to detect and identify the adhesive material, so as to trigger the first cutting assembly 11 and the second cutting assembly 12 respectively to accurately cut and separate two adjacent sheet units, so as to realize accurate and synchronous double cutting operations during the continuous conveying process of the sheet material 201, thereby effectively removing the adhesive material. By accurately removing the adhesive material successfully cut from between two adjacent sheet units and effectively transferring it away from the sheet units, the cleanliness of the processed area after cutting and the smooth progress of subsequent processes are ensured, ensuring the smoothness, high efficiency and stable product quality of the entire die-cutting process. And the stability and accuracy of the entire extraction process are ensured, effectively preventing problems such as offset or wrinkles of the material during the moving process, thereby optimizing the working efficiency and effect of the entire die-cutting device 1. In addition, highly automated and precise operations are realized during the entire die-cutting process, effectively ensuring the yield rate and consistency of each sheet unit after cutting.

[0086] This application also provides a conveying device, please refer to Figure 2 , Figure 2Schematic structural diagram of a conveying device according to some embodiments. In some embodiments, the conveying device 30 includes a transmission device 31 and a die-cutting device 32. The die-cutting device 32 includes a cutting mechanism 321 and a detection sensor 322. The transmission device 31 is used to convey a sheet material 301, and the cutting mechanism 321 is arranged corresponding to the transmission device 31.

[0087] Among them, the conveying device mainly consists of two major parts, namely the transmission device 31 and the die-cutting device 32. The transmission device 31 is mainly used to continuously and orderly and accurately convey a sheet material 301, such as paper, film, label, etc. to a predetermined position. The die-cutting device 32 is responsible for performing a shaping cutting operation on the conveyed sheet material 301. The die-cutting device 32 internally includes two key components, a cutting mechanism 321 and a detection sensor 322. The cutting mechanism 321 is exquisitely designed, corresponding to and closely combined with the transmission device 31 to ensure accurate and efficient cutting when the material reaches the preset cutting point. The detection sensor 322 is usually used to detect parameters such as the position, color change, thickness of the sheet material, and transmit this information to the controller in real time. Through this linkage mechanism, when the detection sensor 322 captures a specific mark on the sheet material or reaches a preset condition, it will send a trigger signal to the controller, and then control the cutting mechanism 321 to perform precise cutting operations.

[0088] Through the above method, the entire system can realize an automated assembly line operation from material transmission to die-cutting and forming, improving production efficiency and product quality consistency.

[0089] It should be noted that the die-cutting device 32 in this embodiment is the die-cutting device 1 described in the above embodiment. For details, please refer to Figure 1 and the relevant text content, which will not be elaborated here one by one.

[0090] In some embodiments, the transmission device 31 further includes a feeding roller 311 and a receiving roller 312. The feeding roller 311 and the receiving roller 312 are arranged on opposite sides corresponding to the die-cutting device 32. The feeding roller 311 is configured to convey the coiled sheet material 301 in a sheet form towards the die-cutting device 32, and the receiving roller 312 is configured to convey the sheet units obtained by cutting the sheet material 301 by the die-cutting device 32.

[0091] Among them, the feeding roller 311 and the material receiving roller 312 are respectively arranged on opposite sides of the die-cutting device 32 to form a complete material input and output system. The specific working process is as follows: The feeding roller 311 is set to carry and release the sheet material 301 in a roll form, and through precise control, it is transmitted towards the die-cutting device 32 in a continuous sheet form to ensure a stable and orderly supply of the sheet before cutting. The material receiving roller 312 undertakes the task of receiving the sheet units that have been successfully cut by the die-cutting device 32, and collects and winds these cut independent units in a preset manner for subsequent sorting, packaging, or further processing.

[0092] Through the above method, the entire process from feeding to cutting and then to material receiving realizes an automated assembly line operation, significantly improving production efficiency and product quality.

[0093] In some embodiments, the transmission device 31 further includes a third transmission roller 313. The third transmission roller 313 is arranged between the feeding roller 311 and the material receiving roller 312 and is spaced from the die-cutting device 32. The third transmission roller 313 is configured to transmit the sheet material 301.

[0094] Among them, the transmission device 31 further includes a third transmission roller 313 located between the feeding roller 311 and the material receiving roller 312. The third transmission roller 313 is kept at a certain interval from the die-cutting device 32. Its main function is to provide additional conveying support during the process of assisting the sheet material 301 to smoothly transition from the feeding roller 311 to the material receiving roller 312. The third transmission roller 313 is one or more and is spaced between the feeding roller 311 and the material receiving roller 312 according to actual needs. Specifically, the sheet material 301 released by the feeding roller 311 and initially flattened will first pass through the third transmission roller 313 for secondary positioning and tensioning transmission to ensure that the material has an ideal flatness and a stable speed before entering the die-cutting device 32, thereby improving the cutting accuracy and efficiency. After die-cutting, these sheet materials that have been cut into independent units will be accurately transmitted to the material receiving roller 312 for collection under the action of the third transmission roller 313.

[0095] Through the above method, the smoothness and automation degree of the entire production process are ensured.

[0096] In some embodiments, the transmission device 31 further includes a conveyor belt (not shown in the figure). The conveyor belt is connected to the die-cutting device 32 and is configured to be transmitted through the die-cutting device 32 and carry the sheet material 301 transmitted in a sheet form.

[0097] Among them, the conveyor belt is connected to the die-cutting device 32. Its main function is to carry the sheet material 301 released from the unwinding roller 311 and conveyed through the third transfer roller 313, and continue to convey it to the die-cutting device 32 in a stable sheet form for precise cutting. In some embodiments, the conveyor belt can be tensioned and conveyed through the die-cutting device 32 and at least part of the third transfer roller 313. In some other embodiments, the conveyor belt can also be tensioned and conveyed through the unwinding roller 311, the winding roller 312 and all the devices between them. During specific operation, the sheet material 301 moves flat and orderly on the conveyor belt to ensure accurate alignment with the cutting position when entering the die-cutting area.

[0098] In the above manner, after the sheet material 301 is cut, the sheets that have been separated into independent units can continue to be smoothly carried away from the die-cutting device 32 by the conveyor belt and finally sent to the winding roller 312 for collection and sorting, thus forming an efficient and continuous automated production process.
