Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laminated label preparation equipment, in particular to a compound die-cutting machine. BACKGROUND

[0002] As an important information storage and transmission carrier, the preparation technology of laminated electronic labels has evolved with the development of radio frequency identification (RFID), flexible electronics and functional composite materials. Early electronic labels mostly used single-layer or simple double-layer structures. With the increasing requirements of application scenarios on label performance, durability and integration, multi-layer composite structures have gradually become the mainstream. Currently, laminated electronic labels have developed from the initial single-layer or double-layer basic laminates to a multi-layer composite system including substrate layers, functional layers (such as metal antennas, chip embedding layers), adhesive layers and protective layers, etc. to meet the requirements of electrical performance, mechanical strength and packaging reliability in different environments.

[0003] Currently, laminated electronic labels are mostly prepared by laminating and die-cutting processes, which realize the integration of multi-layer materials through layer-by-layer alignment, pressing and curing. Typical preparation equipment includes unwinding devices, guide mechanisms, alignment systems, pressing units and winding modules, etc. Existing equipment is usually optimized for one or a few fixed layer number structures, such as common three-layer (such as substrate-adhesive layer-protection film) or four-layer (such as PET substrate-aluminum foil-adhesive layer-protection film) electronic label preparation systems.

[0004] However, the existing laminated electronic label preparation technology still has significant limitations, especially in the aspects of layer number restriction and equipment adaptability. The current compound die-cutting equipment can only be used for compound die-cutting of labels with four layers or less, and cannot be adapted to five-layer laminated labels, forcing enterprises to rely on high-priced custom equipment. Moreover, a single compound die-cutting equipment usually only supports the preparation of labels with fixed layer numbers, and it is difficult to realize the quick switching and production of labels with different layer numbers on a single equipment.

[0016] The technical solution of the present invention adopts a frame-integrated unwinding component, a roll-feeding component, a die-cutting component and four groups of independently controllable composite components, so that the unwinding component and the roll-feeding component are used to make the bottom paper tape pass through four composite positions in sequence along the first path, and the roll-feeding component can independently transmit the corresponding material tape to each composite position according to the preparation requirements of the number of layers of the finished label, so as to use the four groups of composite components to complete the precise hot pressing composite of the bottom paper tape and the bottom liner paper tape, label tape, surface liner paper tape and surface paper tape in sequence, and finally form a finished label after die-cutting processing by the die-cutting component. In the layer-by-layer composite mode, since the roll-feeding component can independently transport each material tape, and each group of composite components can be independently controlled to start and stop, the bottom paper tape is transported along the first path. When only the label tape and the face paper tape are conveyed to the corresponding composite position, and only the composite components corresponding to the second composite position and the fourth composite position are enabled, a three-layer label including a bottom paper layer, a label layer and a face paper layer can be prepared; when only the bottom liner tape, the label tape and the face paper tape are conveyed to the corresponding composite position, and the composite components corresponding to the first composite position, the second composite position and the fourth composite position are enabled, a three-layer label including a bottom paper layer, a label layer and a face paper layer can be prepared. A four-layer label comprising a base paper layer, a bottom liner layer, a label layer, and a face paper layer; when only the label tape, the face liner tape, and the face paper tape are conveyed to the corresponding composite positions, and the composite components corresponding to the second, third, and fourth composite positions are enabled, a four-layer label comprising a base paper layer, a label layer, a face liner layer, and a face paper layer can be prepared; when each material tape is conveyed to the corresponding composite position, and the composite components corresponding to all four composite positions are enabled, a five-layer label comprising a base paper layer, a bottom liner layer, a label layer, a face liner layer, and a face paper layer can be prepared. In this way, the composite die-cutting machine can realize the rapid switching production of labels with different numbers of layers by a single device without the need to replace hardware and re-debug, and can adapt to the preparation of five-layer labels, solving the problem that existing composite die-cutting equipment cannot adapt to the preparation of five-layer labels and that a single device is difficult to switch to produce labels with different numbers of layers.

[0017] In addition, a multi-layer joint lamination mode can also be used, that is, a roll-feeding assembly is used to transport the base paper strip along the first path, and the remaining multiple material strips required for preparing the finished label are conveyed to the corresponding lamination positions, but only the lamination assembly corresponding to the fourth lamination position is activated (that is, only one set of lamination assemblies is activated), so that the hot pressing lamination of multiple material strips is completed at the fourth lamination position at one time. Compared with the layer-by-layer lamination mode, the multi-layer joint lamination mode only performs lamination once in the entire process, so the corresponding lamination control method of the multi-layer joint lamination mode is simpler, and the overall lamination die-cutting process is more fluid, which is suitable for lamination die-cutting operations with low precision requirements. The layer-by-layer lamination mode can lamination each material strip immediately after it is transported to the corresponding lamination position. Therefore, during the transportation and die-cutting processes after lamination, relative displacement between the laminated layers of material strips is less likely to occur, and the relative positioning accuracy is higher. It is suitable for lamination die-cutting operations with high precision requirements, so as to produce high-precision finished labels.

[0018] In addition, this composite die-cutting machine integrates the unwinding component, the feeding component, the compound component and the die-cutting component, so that the material belt can complete the entire process of unwinding, transportation, compounding and die-cutting within the frame, reducing the number of transfers and path lengths required for traditional multi-device series connection, reducing energy consumption and site occupancy, and improving production efficiency and equipment adaptability.

[0026] As an important information storage and transmission medium, the manufacturing technology of layered electronic tags has continued to evolve with the development of radio frequency identification (RFID), flexible electronics, and functional composite materials. Early electronic tags mostly used single-layer or simple double-layer structures. As application scenarios have increased the requirements for tag performance, durability, and integration, multi-layer composite structures have gradually become mainstream. Currently, layered electronic tags have evolved from the initial single-layer or double-layer basic stack to a multi-layer composite system that includes a substrate layer, functional layers (such as metal antennas and chip embedding layers), adhesive layers, and protective layers to meet the electrical performance, mechanical strength, and packaging reliability requirements in different environments.

[0027] Currently, layered electronic tags are mostly manufactured using lamination and die-cutting processes, integrating multiple layers through layer-by-layer alignment, lamination, and curing. Typical manufacturing equipment includes an unwinder, guide mechanism, alignment system, lamination unit, and rewinding module. Existing equipment is typically optimized for one or more fixed-layer structures, such as the common three-layer (e.g., substrate-adhesive layer-protective film) or four-layer (e.g., PET substrate-aluminum foil-adhesive layer-protective film) electronic tag manufacturing systems.

[0028] However, existing technologies for producing layered electronic labels still have significant limitations, particularly regarding the number of layers and equipment adaptability. Current composite die-cutting equipment can only handle labels with fewer than four layers and is incapable of adapting to five-layer labels, forcing companies to rely on expensive custom equipment. Furthermore, a single composite die-cutting machine typically only supports the production of labels with a fixed number of layers, making it difficult to quickly switch between and produce labels with different layer counts on a single machine.

[0029] In order to solve the above problems, the present invention provides a compound die-cutting machine.

[0030] See also Figure 1In one embodiment of the present invention, the compound die-cutting machine is used to prepare layered labels. The compound die-cutting machine includes a frame 1200, a roll-feeding assembly 1000, a die-cutting assembly 2000, multiple unwinding assemblies 3000, and four compounding assemblies 4000. The multiple unwinding assemblies 3000 are all arranged on the frame, and different material belts are wound around the periphery of different unwinding assemblies 3000; the material belts include a bottom paper belt, a bottom liner paper belt, a label belt, a surface liner paper belt, and a face paper belt; the roll-feeding assembly 1000 is arranged on the frame, and the material belt passes through the roll-feeding assembly 1000, and the roll-feeding assembly 1000 is used to transport the bottom paper belt along a first path; wherein the first path is provided with four compounding positions in sequence from upstream to downstream; the roll-feeding assembly 1000 is also used to independently transport the remaining material belts to deliver the bottom liner paper belt to the first compounding The laminating position 5100, and / or the label tape is conveyed to the second laminating position 5200, and / or the surface lining paper tape is conveyed to the third laminating position 5300, and / or the surface paper tape is conveyed to the fourth laminating position 5400; four groups of laminating components 4000 are correspondingly arranged on the four laminating positions, and each group of laminating components 4000 is independently controlled to start and stop; the laminating components 4000 are used to hot-press and laminate different material tapes on the corresponding laminating positions; wherein, 1 to 4 groups of the four laminating components 4000 are activated according to the number of preparation layers of the finished label; the die-cutting component 2000 is arranged downstream of the fourth laminating position 5400, and the die-cutting component 2000 is used to die-cut the laminated tape to be die-cut to obtain a finished label; wherein, the finished label at least includes a base paper layer, a label layer and a surface paper layer laminated in sequence from bottom to top.

[0031] The technical solution of the present invention adopts a frame-integrated unwinding component 3000, a roll-feeding component 1000, a die-cutting component 2000 and four groups of independently controllable composite components 4000, so that the unwinding component 3000 and the roll-feeding component 1000 are used to make the bottom paper tape pass through four composite positions in sequence along the first path, and the roll-feeding component 1000 can independently transmit the corresponding material tape to each composite position according to the preparation requirements of the number of layers of the finished label, so that the four groups of composite components 4000 are used to complete the precise hot pressing composite of the bottom paper tape and the bottom liner paper tape, label tape, surface liner paper tape and surface paper tape layer by layer in sequence, and finally form a finished label after die-cutting processing by the die-cutting component 2000. In the layer-by-layer composite mode, since the roll-feeding assembly 1000 can independently transport each material tape, and each group of composite assemblies 4000 can be independently controlled to start and stop, the bottom paper tape is transported along the first path. When only the label tape and the face paper tape are delivered to the corresponding composite positions, and only the composite assemblies 4000 corresponding to the second composite position 5200 and the fourth composite position 5400 are enabled (e.g. Figure 2 As shown), a three-layer label including a base paper layer, a label layer and a face paper layer can be prepared; when only the bottom liner tape, the label tape and the face paper tape are transferred to the corresponding composite positions, and the composite components 4000 corresponding to the first composite position 5100, the second composite position 5200 and the fourth composite position 5400 are enabled (as shown), Figure 3 As shown), a four-layer label including a base paper layer, a bottom liner layer, a label layer and a face paper layer can be prepared; when only the label tape, the face liner tape and the face paper tape are transferred to the corresponding composite positions, and the composite components 4000 corresponding to the second composite position 5200, the third composite position 5300 and the fourth composite position 5400 are enabled (as shown), Figure 4 As shown), a four-layer label including a bottom paper layer, a label layer, a surface liner layer and a surface paper layer can be prepared; when each material belt is conveyed to the corresponding composite position, and the composite components 4000 corresponding to the four composite positions are all enabled (as shown Figure 1 As shown in the figure, it can produce five-layer labels consisting of a base paper layer, a bottom liner layer, a label layer, a top liner layer, and a top paper layer. This allows a single machine to quickly switch between producing labels with different numbers of layers without having to replace hardware or re-commission. Furthermore, it can accommodate the production of five-layer labels, resolving the issues with existing composite die-cutting equipment being unable to adapt to five-layer label production and the difficulty of switching between production of labels with different numbers of layers on a single machine.

[0032] Alternatively, a multi-layer joint lamination mode can be employed, whereby the roll feed assembly 1000 transports the base paper web along the first path and delivers the remaining multiple material webs required for the finished label to the corresponding lamination stations. However, only the lamination assembly corresponding to the fourth lamination station 5400 is activated (i.e., only one set of lamination assemblies is activated), thereby completing the hot-press lamination of multiple material webs at once at the fourth lamination station 5400. Compared to the layer-by-layer lamination mode, the multi-layer joint lamination mode only laminates once throughout the entire process, resulting in simpler lamination control and a smoother overall lamination die-cutting process. This makes it suitable for lamination die-cutting operations with lower precision requirements. In contrast, the layer-by-layer lamination mode allows for lamination of each material web immediately after it arrives at the corresponding lamination station. Therefore, relative displacement between the laminated layers is less likely to occur during transportation and die-cutting, resulting in higher relative positioning accuracy. This makes it suitable for lamination die-cutting operations with higher precision requirements, enabling the production of high-precision finished labels.

[0033] In addition, this composite die-cutting machine uses an integrated layout of the unwinding component 3000, the feeding component 1000, the compounding component 4000 and the die-cutting component 2000, so that the material belt can complete the entire process of unwinding, transportation, compounding and die-cutting within the frame, reducing the number of transfers and path lengths required for traditional multi-device series connection, reducing energy consumption and site occupancy, and improving production efficiency and equipment adaptability.

[0034] In addition, the unwinding assembly 3000 may include basic driving devices, unwinding shafts and other components. The driving device may be configured as a driving component such as a servo motor. The driving device is connected to the unwinding shaft by transmission, so that the driving device drives the unwinding shaft to rotate, thereby unwinding the material belt wound on the unwinding shaft.

[0035] In addition, the feeding assembly 1000 can include multiple sets of feeding mechanisms, each set of feeding mechanisms corresponding to transporting one material tape, so that the base paper tape is transported along the first path by one set of feeding mechanisms, and the remaining four material tapes are independently transported by the corresponding sets of feeding mechanisms from the corresponding unwinding assemblies 3000 to the corresponding composite positions. For example, when a three-layer finished label needs to be prepared, one set of feeding mechanisms transports the base paper tape along the first path, another set of feeding mechanisms can transport the label tape to the second composite position, and another set of feeding mechanisms can transport the face paper tape to the fourth composite position, and the remaining sets of feeding mechanisms can be stopped. The feeding assembly 1000 can include guide rollers, driving devices, and the like, so that the driving device drives the guide rollers to move the material tape on the surface of the guide rollers along a specific path.

[0036] The composite assembly 4000 can have a hot press roller and a pressure plate / pressure roller and the like pressure support components matched with the hot press roller. The driving device of the composite assembly 4000 applies pressure to the hot press roller, so that the hot press roller applies pressure to the support component, so that the material tape passing between the hot press roller and the support component is hot-pressed and compounded. The driving device of the composite assembly 4000 can be one of various driving components such as a motor, an air cylinder, an oil cylinder, and the like, which will not be described one by one here.

[0037] The die-cutting assembly 2000 can adopt a scheme in which a driving device and a die-cutting knife are matched with each other. The driving device is in transmission connection with the die-cutting knife, so that the driving device drives the die-cuting knife to die-cut the material tape to be cut. The die-cutting assembly 2000 can also adopt a scheme in which a moving device and a laser generator are matched with each other. The laser generator emits laser to cut the material tape to be cut. The moving device moves the laser generator, so that the material tape to be cut is cut into a desired shape, and a finished label is obtained. Of course, other die-cutting methods can also be adopted, which will not be described one by one here.

[0038] In addition, as an optional embodiment, the composite die-cutting machine can also include a control module. The control module can be an electronic device such as a computer, a microcontroller unit (MCU), a programmable logic controller (PLC), and the like. The control module can be in communication connection with the feeding assembly 1000, the die-cutting assembly 2000, the multiple sets of unwinding assemblies 3000, and the four sets of composite assemblies 4000, respectively. The control module can be used to control the start and stop of each component and related operating parameters, such as adjusting the feeding speed of the feeding assembly 1000, adjusting the temperature and applied pressure during the hot-pressing and compounding process of the composite assembly 4000, and the like. Thus, the control module can be used to uniformly control each assembly.

[0039] Please refer to Figure 1 and Figure 5In an embodiment of the present invention, the types of label tapes include dry inlay tapes and wet inlay tapes. The dry inlay tape has multiple chip labels, and the wet inlay tape includes at least two adhesive layers and multiple label sheets located between the two adhesive layers. The compound die-cutting machine also includes a breaking and transferring component 6000 and a traction mechanism 7000. The breaking and transferring component 6000 is arranged along the first path between the first compound position 5100 and the second compound position 5200. The traction mechanism 7000 is arranged along the first path between the breaking and transferring component 6000 and the second compound position 5200. When When the label tape is a dry inlay tape, the roll-feeding assembly 1000 is also used to convey the dry inlay tape to the breaking and transferring assembly 6000, which is used to break the dry inlay tape into individual chip labels and transfer the chip labels to the bottom paper tape or the bottom liner tape, so that the label sheet can be conveyed to the second composite position 5200 for composite; when the label tape is a wet inlay tape, the roll-feeding assembly 1000 is also used to convey the wet inlay tape to the traction mechanism 7000, which is used to pull the wet inlay tape to the second composite position 5200.

[0040] It should be noted that the inlay in this embodiment refers to what is commonly known as Inlay in the industry. The electronic tag Inlay is a pre-laminated product composed of multiple layers of plastic sheets, chips and coils, usually composed of two or three layers. It can also be understood as a semi-finished product that is not packaged with an RFID tag. Inlay can be used to make different types of electronic tags through different forms of packaging. Inlay is divided into two types: dry inlay (Dry Inlay) and wet inlay (Wet Inlay), which correspond to the dry inlay tape and wet inlay tape in this embodiment respectively. Dry inlay (dry inlay tape) generally uses a polyester substrate, while wet inlay (wet inlay tape) usually uses a release paper substrate, and wet inlay is usually coated with an adhesive layer on the surface of the chip layer where the chip and antenna are located and attached to the release paper. The adhesive layer usually uses hot melt adhesive. Because the wet inlay has its own adhesive layer, after the release paper is peeled off, the wet inlay, consisting solely of the adhesive layer and the chip layer, is transported to the lamination station. Heat pressing can then be used to melt the adhesive layer, allowing the wet inlay to adhere to the corresponding material tape. This eliminates the need for applying adhesive to the corresponding material tape or wet inlay before lamination. The wet inlay tape in this embodiment has already had its release film removed before being transported to the traction mechanism 7000. Therefore, the wet inlay tape can consist solely of two adhesive layers and multiple label sheets positioned between them.

[0041] In this embodiment, by adding a breaking and transferring component 6000 and a traction mechanism 7000 to the frame, and using the breaking and transferring component 6000 and the traction mechanism 7000 to process dry inlay tape and wet inlay tape respectively, the compound die-cutting machine can adapt to different types of label tapes; when the label tape is a dry inlay tape (such as Figure 1As shown), the roll-feeding component 1000 delivers the dry inlay tape to the breaking and transferring component 6000, which first accurately breaks the continuous tape into individual chip labels, and then transfers the chip labels to the bottom paper tape or the bottom liner tape, and then the roll-feeding component 1000 continues to transport it to the second laminating position 5200, thereby ensuring the accurate positioning of the chip label with the bottom paper layer or the bottom liner layer in the subsequent laminating process, avoiding chip spacing errors and inter-layer mis-sticking caused by the continuous transportation of the entire roll of dry inlay tape; when the label tape is a wet inlay tape (such as Figure 5 As shown, the roll-feeding assembly 1000 delivers the wet inlay tape to the traction mechanism 7000. The traction mechanism 7000 directly pulls the wet inlay tape, containing two adhesive layers and multiple label sheets, to the second laminating station 5200, achieving continuous lamination without interruption. This effectively utilizes the wet inlay tape's inherent adhesive layer to heat-press the base paper layer or the bottom liner layer in a single process, eliminating the need for additional gluing steps and reducing adhesive quantity fluctuations. This composite die-cutting machine enables a single composite die-cutting machine to laminate and die-cut both dry and wet inlay label tapes. Furthermore, through precise control of the interruption transfer assembly 6000 and the traction mechanism 7000, the positioning accuracy and interlayer bonding strength of different label types at the laminating station are guaranteed, further improving the yield rate and performance consistency of the finished labels.

[0042] The operator can adjust the roll-feeding assembly 1000 so that the roll-feeding assembly 1000 can transport the label tape to the breaking and transferring assembly 6000 or the traction mechanism 7000. For example, the roll-feeding assembly 1000 can include multiple guide rollers, and the label tape passes through the multiple guide rollers. The operator can adjust the direction of the label tape around the guide rollers. For example, if the breaking and transferring assembly 6000 and the traction mechanism 7000 are respectively located on the left and right sides of the first guide roller, then by adjusting the winding direction of the label tape, when the unrolled label tape is a dry inlay tape, the operator allows the dry inlay tape wound around the first guide roller to be transported to the left, so that the breaking and transferring assembly 6000 can receive the dry inlay tape; when the unrolled label tape is a wet inlay tape, the operator allows the wet inlay tape wound around the first guide roller to be transported to the right, so that the traction mechanism 7000 can receive the wet inlay tape. In this way, the composite die-cutting machine can be adapted to dry inlay tapes and wet inlay tapes, that is, the switching between dry inlay mode and wet inlay mode can be achieved.

[0043] In addition, by combining the start and stop control of the above-mentioned roll feeding component 1000 and the four-group composite component 4000, and the corresponding activation of the interruption transfer component 6000 and the traction mechanism 7000 in this embodiment, it is possible to achieve the switching of the number of layers of finished label preparation and the dry inlay and wet inlay. Taking the conversion of the preparation of three-layer finished labels of dry inlay tape to the preparation of five-layer finished labels of wet inlay tape as an example, it is explained: when it is necessary to prepare a three-layer finished label, and the label tape is a dry inlay tape (dry inlay) (such as Figure 2As shown), the roll-feeding assembly 1000 can be used to transport the base paper tape along the first path, and the roll-feeding assembly 1000 can be used to transfer the dry inlay tape to the breaking and transferring assembly 6000, so that the dry inlay tape is broken and transferred to the base paper tape and transported to the second composite position; the roll-feeding assembly 1000 can also be used to transfer the surface paper tape to the fourth composite position; the composite assemblies 4000 corresponding to the second composite position 5200 and the fourth composite position 5400 are activated, so that the dry inlay tape and the base paper tape are composited at the second composite position, and the composited dry inlay layer and the base paper layer are composited with the surface paper tape at the fourth composite position. When it is necessary to convert the five-layer finished label of wet inlay tape (wet inlay) into a finished label (such as Figure 5 As shown, the operator can replace the dry inlay tape in the unwind assembly 3000 corresponding to the label tape with a wet inlay tape to unwind the wet inlay tape. The operator also needs to adjust the direction of the wet inlay tape around the guide roller in the feed assembly 1000 (for example, the label tape passing around the first guide roller is now transported to the right instead of the original left), so that the traction mechanism 7000 receives the wet inlay tape. The operator then activates all unwind assemblies 3000, the feed assembly 1000, and the traction mechanism 7000 to transport the base paper tape along the first path and the remaining material tapes to the corresponding laminating positions. The wet inlay tape passes through the feed assembly 1000 and the traction mechanism 7000 in sequence and is transported to the second laminating position. Simultaneously, all four laminating assemblies are activated, achieving layer-by-layer lamination at each laminating position. This allows the adjustment of the number of layers in the finished label and the switching between dry and wet inlay modes.

[0044] In other cases, refer to the above operation method, and Figures 1 to 8 The corresponding roll-feeding assembly 1000, four-group composite assembly 4000, breaking and transferring assembly 6000, and traction mechanism 7000 are activated. When it is necessary to prepare a five-layer finished label and the label tape is a dry inlay tape, you can refer to Figure 1 When you need to prepare a four-layer finished label with a bottom liner layer, and the label tape is a dry inlay tape, you can refer to Figure 3 When you need to prepare a four-layer finished label with a surface backing paper layer, and the label tape is a dry inlay tape, you can refer to Figure 4 When you need to prepare a three-layer finished label and the label tape is a wet inlay tape, you can refer to Figure 6 When you need to prepare a four-layer finished label with a bottom liner layer and the label tape is a wet inlay tape, you can refer to Figure 7 When you need to prepare a four-layer finished label with a surface backing paper layer and the label tape is a wet inlay tape, you can refer to Figure 8 .

[0045] The compound die-cutting machine may also include a stripping mechanism, located adjacent to the roll-feeding assembly 1000. After the roll-feeding assembly 1000 releases the material web, a stripping blade on the stripping mechanism is used to peel away protective layers such as release film, polyester film, or release paper from the web, leaving the desired material for transport. A waste roll collection mechanism may also be located adjacent to the stripping mechanism to recycle the protective film. The structure of the waste roll collection mechanism is similar to that of the unwinding assembly 3000 and will not be further described here.

[0046] See also Figure 1 In an embodiment of the present invention, the interruption and transfer assembly 6000 includes an interruption structure (not shown in the figure), a transfer hub (not shown in the figure) and a first driving component (not shown in the figure). The first driving component is rotatably connected to the interruption structure and the transfer hub respectively. The interruption structure includes a rotating shaft and a blade. The blade is set on the rotating shaft and rotates with the rotating shaft; the transfer hub is located below the interruption structure, and the rotation direction of the transfer hub is opposite to the rotation direction of the rotating shaft; one of the left and right sides of the transfer hub is a negative pressure wheel part, and the left side of the transfer hub is a negative pressure wheel part. The other side portion in the right side portion is the positive pressure wheel portion, the upper dividing point between the negative pressure wheel portion and the positive pressure wheel portion is the breaking area, and the lower dividing point between the negative pressure wheel portion and the positive pressure wheel portion is the transfer area; when the label tape is a dry inlay tape, the roll feeding assembly 1000 is used to transport the dry inlay tape to the breaking area, so that the dry inlay tape is broken into a single chip label by the blade, and the chip label is adsorbed on the surface of the transfer hub; the transfer hub is used to rotate the chip label to the transfer area and separate the chip label, so that the chip label is attached to the base paper tape or the bottom liner paper tape.

[0047] In this embodiment, the interruption and transfer assembly 6000 is configured to include an interruption structure, a transfer hub and a first driving component, and the rotating shaft of the interruption structure carries the blade to rotate, and the transfer hub rotates in opposite directions, and the left and right sides of the transfer hub respectively form a negative pressure wheel part and a positive pressure wheel part, the upper dividing point of the negative pressure wheel part and the positive pressure wheel part constitute the interruption area, and the lower dividing point constitutes the transfer area, so that when the dry inlay tape enters the interruption area, the rotating blade will accurately cut the continuous dry inlay tape into a single chip label, and the vacuum adsorption force generated by the negative pressure wheel part at the moment of cutting will immediately and stably adsorb the chip label on the surface of the transfer hub. The positive pressure wheel releases positive pressure airflow, so that the chip label is pushed away from the transfer hub surface while the vacuum adsorption is released, and is precisely attached to the bottom paper tape or the bottom liner tape; since the blade and the transfer hub rotate in opposite directions, the cutting action and the adsorption action are completed instantaneously in the interruption area, which not only improves the interruption efficiency but also reduces the tensile deformation of the dry inlay tape. At the same time, the continuous switching of negative pressure and positive pressure realizes the lossless transfer of the chip label, avoiding the chip damage or adhesive layer contamination caused by traditional mechanical grasping.

[0048] Among them, the outer periphery of the transfer hub is provided with multiple ventilation holes, and the interior of the transfer hub can be provided with two left and right chambers, the two chambers are isolated from each other, and the ventilation holes are connected to the corresponding chambers on the side where they are located. One of the chambers can be connected to the air outlet device, and the other chamber can be connected to the suction device, thereby forming a positive pressure air outlet effect for the ventilation holes corresponding to one of the chambers, and forming a negative pressure adsorption effect for the ventilation holes corresponding to the other chamber.

[0049] In an embodiment of the present invention, the traction mechanism 7000 includes a transmission roller (not shown in the figure), a first pressure roller (not shown in the figure), and a third driving component (not shown in the figure). The third driving component is connected to the transmission roller, and the transmission roller and the first pressure roller jointly press the upper and lower sides of the wet inlay tape. The third driving component is used to drive the transmission roller to rotate so that the wet inlay tape is transferred to the second composite position 5200.

[0050] In this embodiment, the traction mechanism 7000 includes a transmission roller, a first pressure roller and a third driving component, and the third driving component directly drives the transmission roller to rotate, so that the transmission roller and the first pressure roller jointly perform synchronous rolling pressure on the upper and lower sides of the wet inlay tape, thereby applying a stable and continuous forward traction force to the wet inlay tape before it enters the second composite position 5200; since the wet inlay tape does not need to be interrupted and transferred, it is directly transported to the second composite position 5200 through the rolling and traction of the traction mechanism 7000, thereby shortening the process path, reducing energy consumption and improving overall production efficiency.

[0051] See also Figure 1 In the embodiment of the present invention, the roll-feeding assembly 1000 includes multiple roll-feeding mechanisms, each roll-feeding mechanism includes a second driving component (not shown in the figure) and a guide roller group, the second driving component is connected to the guide roller group, and each roll-feeding mechanism is independently controlled to start and stop; the bottom paper belt passes through the guide roller group of the first roll-feeding mechanism 1010, and the first roll-feeding mechanism 1010 is used to transport the bottom paper belt along the first path; the bottom liner paper belt passes through the guide roller group of the second roll-feeding mechanism 1020, and the second roll-feeding mechanism 1020 is used to transport the bottom liner paper belt along the first path; The tape is transported to the first composite position 5100; the label tape passes through the guide roller group of the third group of roll feeding mechanism 1030, and the third group of roll feeding mechanism 1030 is used to transport the label tape to the second composite position 5200; the surface lining paper tape passes through the guide roller group of the fourth group of roll feeding mechanism 1040, and the fourth group of roll feeding mechanism 1040 is used to transport the surface lining paper tape to the third composite position 5300; the surface paper tape passes through the guide roller group of the fifth group of roll feeding mechanism 1050, and the fifth group of roll feeding mechanism 1050 is used to transport the surface paper tape to the fourth composite position 5400.

[0052] In the present embodiment, the winding assembly 1000 is set to contain five groups of independently started and stopped second driving components and guide roller groups, and the base paper tape, the bottom liner tape, the label tape, the top liner tape and the face paper tape are respectively driven and guided by the first group of winding mechanisms 1010, the second group of winding mechanisms 1020, the third group of winding mechanisms 1030, the fourth group of winding mechanisms 1040 and the fifth group of winding mechanisms 1050, so as to realize independent closed-loop control of tension, speed and position before each material tape enters the corresponding composite position, thereby avoiding the misregistration, wrinkles or tensile deformation between layers caused by speed difference or uneven tension when multiple layers are unwound at the same time. When preparing a three-layer label, only the first group of winding mechanisms 1010, the third group of winding mechanisms 1030 and the fifth group of winding mechanisms 1050 need to be started, and the bottom liner tape and the top liner tape remain stationary, thereby reducing invalid material running and material waste; when preparing a four-layer label, the second group of winding mechanisms 1020 or the fourth group of winding mechanisms 1040 is additionally started, so as to quickly insert the bottom liner layer between the base paper layer and the label layer, or insert the top liner layer between the label layer and the face paper layer; when preparing a five-layer label, all the five groups of winding mechanisms are started, and each guide roller group is driven by the independent second driving component to run at a preset speed, thereby ensuring that the five layers of materials are accurately overlaid in sequence at the four composite positions. Since each group of winding mechanisms can be independently started and stopped and the path of the guide roller group is fixed, the operator only needs to switch the start and stop state of the corresponding winding mechanism to complete the changeover of labels with different numbers of layers, without the need to re-adjust the mechanical structure, thereby significantly shortening the changeover time and reducing the operation complexity, while ensuring the tension stability and alignment accuracy of each layer of material under high-speed operation, improving the yield rate of finished labels and production flexibility.

[0053] Among them, as an optional embodiment, the compound die-cutting machine can also include multiple sets of visual detection components. The above-mentioned control module is respectively connected to the multiple sets of visual detection components and the multiple sets of coiling mechanisms. The multiple sets of visual detection components can be arranged around the guide rollers of the coiling mechanism. The visual detection components are used to detect the tightness of the material belt, thereby determining the tension of the material belt; the control module can adjust the speed and other parameters of the coiling mechanism at the corresponding position according to the tension detection of the material belt, thereby preventing the material belt from breaking due to excessive tension. This embodiment achieves adaptive adjustment of operating parameters such as the speed of the coiling mechanism by coordinating the control module with the visual feedback of the visual detection component, thereby effectively improving the degree of automation of the compound die-cutting machine and reducing the degree of manual intervention and the errors that may be caused by manual operation. In addition, a portion of the visual inspection components can also be set at each compounding position and die-cutting component 2000. This portion of the visual inspection components can be used to detect the compound die-cutting conditions of each material strip and provide feedback to the control module. The control module can identify whether the compound die-cutting conditions of the material strip are qualified based on the pre-stored detection algorithm. If unqualified, a warning message can be issued to prompt the operator to intervene, thereby timely intervening in the compound die-cutting process of unqualified products. Among them, the detection algorithm can be a defect detection algorithm, which can be based on a neural network model such as YOLO and CNN, and is obtained by training and testing the model through defect data sets collected from the relevant compounding and die-cutting processes; of course, other detection methods can also be used, which will not be described one by one here.

[0054] See also Figure 1 and Figure 2 In an embodiment of the present invention, the guide roller group of the first group of roll feeding mechanism 1010 includes a first sub-roller group 1011, a second sub-roller group 1012 and a third sub-roller group 1013. The first sub-roller group 1011 is arranged beside the unwinding component 3000 for unwinding the base paper tape; the second sub-roller group 1012 is arranged beside the first composite position 5100; the multiple guide rollers in the third sub-roller group 1013 are respectively arranged at the breaking and transferring component 6000, the traction mechanism 7000, the second composite position 5200, the third composite position 5300, the fourth composite position 5400 and the die-cutting component 20 00; when the composite assembly 4000 located at the first composite position 5100 is started, the bottom paper tape is used to pass through the first sub-roller group 1011, the second sub-roller group 1012 and the third sub-roller group 1013 in sequence, so that the bottom paper tape is transported along the first path; when the composite assembly 4000 located at the first composite position 5100 is closed, the bottom paper tape is used to pass through the first sub-roller group 1011 and the third sub-roller group 1013 in sequence, so that the bottom paper tape is transported along the second path; the second path passes through the second composite position 5200, the third composite position 5300 and the fourth composite position 5400 in sequence.

[0055] In this embodiment, the first sub-roller group 1011, the second sub-roller group 1012 and the third sub-roller group 1013 are arranged in the guide roller group of the first group of winding mechanism 1010, and the first sub-roller group 1011 is adjacent to the unwinding component 3000 corresponding to the bottom paper tape, the second sub-roller group 1012 is adjacent to the first compounding position 5100, and the third sub-roller group 1013 is arranged across the breaking and transferring component 6000, the traction mechanism 7000, the second compounding position 5200, the third compounding position 5300, the fourth compounding position 5400 and the die-cutting component 2000. Therefore, when the bottom liner tape and the bottom paper tape need to be compounded (that is, when the compounding component 4000 of the first compounding position 5100 is started), the bottom paper tape can pass through the first sub-roller group 1011, the second sub-roller group 1012, the third sub-roller group 1013 in sequence and move according to the first path, so that the bottom paper tape can be compounded with the bottom liner tape and then participate in the compounding of the subsequent material tape. This situation is as shown in FIG. Figure 1 As shown; when the bottom liner tape and the bottom paper tape do not need to be composited (i.e., when the composite assembly 4000 of the first composite position 5100 is closed), the bottom paper tape directly passes through the second path formed by the first sub-roller group 1011 and the third sub-roller group 1013, avoiding the first composite position 5100 and directly entering the second composite position 5200, thereby shortening the conveying path of the bottom paper tape and improving production efficiency. Figure 2 shown.

[0056] The switching of the bottom paper tape moving along the first path or the second path can be completed by the operator. The operator can change the bottom paper tape transmission path by winding the bottom paper tape around different sub-roller groups.

[0057] See also Figure 1 In an embodiment of the present invention, the compound die-cutting machine also includes four groups of gluing components, which are correspondingly arranged at the upstream of the four compound positions along the first path, and each group of gluing components is independently controlled to start and stop; the roll feeding component 1000 is used to transport the bottom paper tape along the first path and pass through the four groups of gluing components in sequence; the first group of gluing components 8100 is used to glue the bottom paper tape to make the bottom paper tape bonded to the bottom liner paper tape / label tape; the second group of gluing components 8200 is used to glue the bottom liner paper tape to make the bottom liner paper tape bonded to the label tape; the third group of gluing components 8300 is used to glue the label tape to make the label tape bonded to the surface liner paper tape / face paper tape; the fourth group of gluing components 8400 is used to glue the surface liner paper tape to make the surface liner paper tape bonded to the face paper tape.

[0058] In this embodiment, four groups of independently started and stopped gluing components are respectively arranged upstream of the four compounding positions along the first path, and the roll feeding component 1000 drives the bottom paper tape to pass through the four groups of gluing components in sequence along the first path, so that the corresponding gluing components can be selectively activated according to the number of label layers required and whether each material tape is pre-coated with composite glue: when any material tape is pre-coated with composite glue, the gluing component corresponding to the material tape does not need to be opened, and the composite glue pre-coated on the material tape can be directly used for compounding. For the remaining material tapes that are not compounded with the material tape and are not pre-coated with glue, the gluing components corresponding to the remaining material tapes can be activated to perform gluing on the remaining material tapes; when none of the material tapes are pre-coated with composite glue, when preparing a three-layer label, only the first group of gluing components 8100 and the third group of gluing components 8300 need to be activated. The bottom paper tape completes the application of composite glue between the bottom paper layer and the label layer at the first group of gluing components 8100, and the label tape completes the application of composite glue between the bottom paper layer and the label layer at the third group of gluing components. The composite glue application of the label layer and the surface paper layer is completed at 8300. The bottom lining paper tape and the surface lining paper tape have no glue output because the corresponding gluing components are closed, avoiding glue waste and subsequent cleaning. When preparing four-layer labels, the first group of gluing components 8100, the second group of gluing components 8200 and the third group of gluing components 8300 are activated, or the first group of gluing components 8100, the third group of gluing components 8300 and the fourth group of gluing components 8400 are activated, so that the bottom paper tape and the bottom lining paper tape are The tape and label tape obtain composite glue respectively to complete the bonding of the bottom paper layer-bottom lining paper layer-label layer-surface paper layer, or the bottom paper tape, label tape and surface lining paper tape obtain composite glue respectively to complete the bonding of the bottom paper layer-label layer-surface lining paper layer-surface paper layer; when preparing five-layer labels, all four groups of gluing components are started, and the bottom paper tape, bottom lining paper tape, label tape and surface lining paper tape obtain composite glue in turn to achieve complete bonding of the bottom paper layer-bottom lining paper layer-label layer-surface lining paper layer-surface paper layer.

[0059] The gluing assembly can include a driving component, a storage container, a push rod, and a moving device. The storage container is internally provided with a cavity, and the cavity is in communication with the outside through a nozzle. The moving device is in driving connection with the storage container to drive the storage container to move. The push rod is arranged in the storage container and is used to push the composite glue in the storage container to move out. The driving component is in driving connection with the push rod to push the push rod. In this way, the gluing function of the gluing assembly on each material belt can be realized. When gluing is needed, the moving device can drive the storage container to move, so that the nozzle of the storage container abuts against the corresponding material belt or the distance between the nozzle of the storage container and the material belt is shortened to a preset gluing distance. The driving component pushes the push rod, so that the composite glue in the storage container flows out along the nozzle and adheres to the material belt. When the gluing is finished, the moving device can drive the storage container to move reversely, so that the nozzle of the storage container is prevented from contacting the material belt. The moving device can be a single-axis moving platform, which is guided through a guide rail and moves by using a screw nut transmission mode. The specific structure can refer to the existing single-axis moving platform. The driving component can be a gas cylinder or a motor, which will not be described herein.

[0060] Please refer to Figure 1 In the embodiment of the present application, the composite die-cutting machine further comprises a winding assembly 9000 arranged along the first path downstream of the die-cutting assembly 2000, the winding assembly 9000 being used for winding the finished labels; and / or the composite assembly 4000 comprises a hot pressing roller, a second pressing roller, a fourth driving component (not shown in the figure), and a temperature sensor (not shown in the figure). The fourth driving component is in driving connection with the hot pressing roller. The hot pressing roller is internally provided with a passage for the external high-temperature gas or the external high-temperature liquid to pass in. The fourth driving component is used to drive the hot pressing roller to press against the second pressing roller, so that the hot pressing roller and the second pressing roller jointly perform hot pressing and compounding on the multi-layer material belt. The temperature sensor is used to monitor the temperature of the material belt; and / or the composite die-cutting machine further comprises a plurality of deviation correctors 1100 arranged correspondingly downstream of the plurality of unwinding assemblies 3000. The deviation corrector 1100 is used to correspondingly adjust the deviation degree of different material belts from the conveying direction.

[0061] In this embodiment, by arranging a winding component 9000 along the first path downstream of the die-cutting component 2000, the finished label can be continuously wound after die-cutting, avoiding creases and contamination caused by manual handling and reducing the cost of manual winding; by designing the composite component 4000 as an integrated structure of a hot pressing roller, a second pressing roller, a fourth driving component and a temperature sensor, and providing a channel for the circulation of high-temperature gas or high-temperature liquid inside the hot pressing roller, when the fourth driving component drives the hot pressing roller to pressurize the second pressing roller, the heat is quickly and evenly transferred to the multi-layer material belt through the roller surface, achieving instantaneous heating and constant temperature maintenance, and the temperature sensor can feedback the temperature of the material belt so as to adjust the temperature of the gas or liquid introduced according to the temperature of the material belt, thereby ensuring that the material belt can reach the expected composite temperature; by arranging the correctors 1100 downstream of multiple groups of unwinding components 3000, each corrector 1100 independently detects and corrects the offset of the corresponding material belt relative to the transmission direction in real time, thereby improving the inter-layer alignment accuracy.

[0062] The deflection corrector 1100, also known as a deflection controller, is an automated device used in industries such as printing and packaging, papermaking, and film. It is primarily used to correct material deviation during roll production. Currently, various deflection correctors 1100 are available on the market, including the Fife, D-ARISE, and SG series. You can select and purchase a deflection corrector 1100 based on your specific needs. The specific structure of deflection corrector 1100 will not be described here.

[0063] See also Figure 1 In an embodiment of the present invention, the die-cutting assembly 2000 includes a first die-cutting mechanism 2100 and a second die-cutting mechanism 2200. The first die-cutting mechanism 2100 is arranged downstream of the fourth laminating position 5400, and the second die-cutting mechanism 2200 is arranged downstream of the first die-cutting mechanism 2100. The first die-cutting mechanism 2100 and the second die-cutting mechanism 2200 are independently controlled to start and stop; the first die-cutting mechanism 2100 is used to die-cut the laminated tape to be die-cut, so as to cut off the laminated layer located above the base paper layer to obtain a finished tape containing finished labels; the second die-cutting mechanism 2200 is used to die-cut the laminated tape to be die-cut, so as to cut off all the laminated layers and obtain independent finished labels.

[0064] In this embodiment, by sequentially arranging independently activated and deactivated first and second die-cutting mechanisms 2100 and 2200 along the first path downstream of the fourth laminating station 5400, the laminated web to be die-cut can undergo both partial and full die-cutting within the same machine frame. When only the base paper layer is required as the carrier substrate (i.e., partial cut), activating the first die-cutting mechanism 2100 severs the entire composite layer above the base paper layer, leaving the base paper intact, forming a continuous finished web containing finished labels, facilitating subsequent roll packaging or secondary slitting. When individual finished labels are required (i.e., full cut), deactivating the first die-cutting mechanism 2100 and activating the second die-cutting mechanism 2200 sever all composite layers simultaneously, directly producing independent finished labels without waste edges or connection points, eliminating the need for an offline secondary die-cutting process. Operators can quickly switch between partial and full cut modes without stopping the machine by activating and deactivating the first and second die-cutting mechanisms 2100 and 2200, improving switching convenience.

[0065] As an optional embodiment, the first die-cutting mechanism 2100 includes a fifth drive component, a first mounting structure, and a flat blade. The flat blade is detachably mounted on the first mounting structure, and the fifth drive component is in transmission connection with the first mounting structure. The second die-cutting mechanism 2200 includes a sixth drive component, a second mounting structure, and an arc-shaped blade. The circular blade is detachably mounted on the second mounting structure, and the sixth drive component is in transmission connection with the second mounting structure. The flat blade can be understood as a flat plate with a die mounted on it. The flat blade moves vertically downward, impacting the underlying die-cutting tape, thereby severing all composite layers and producing an independent finished label. The circular blade can be understood as a knife roller equipped with an arc-shaped die that is rolled against a smooth anvil roller. The material is sheared as it passes between the two rollers.

[0066] In addition, as an optional embodiment, the label tape has chip labels arranged in an array, and the arrangement direction of the multiple rows of chip labels is perpendicular to the first path. The compound die-cutting machine also includes a striping mechanism, which is arranged along the first path between the fourth compounding position 5400 and the first die-cutting mechanism 2100. The striping mechanism is used to divide the multiple rows of chip labels on the compounded tape to be die-cut into single rows of chip labels.

[0067] In an embodiment of the present invention, the finished label also includes a bottom lining paper layer, and the bottom paper layer, the bottom lining paper layer, the label layer and the surface paper layer are compounded in sequence from bottom to top; and / or, the finished label also includes a surface lining paper layer, and the bottom paper layer, the label layer, the surface lining paper layer and the surface paper layer are compounded in sequence from bottom to top; and / or, the finished label also includes a bottom lining paper layer and a surface lining paper layer, and the bottom paper layer, the bottom lining paper layer, the label layer, the surface lining paper layer and the surface paper layer are compounded in sequence from bottom to top.

[0068] In this embodiment, the finished label can be a four-layer structure and / or a five-layer structure. In the four-layer structure, the finished label is composed of a base paper layer, a bottom lining paper layer, a label layer and a surface paper layer, which are compounded in sequence from bottom to top, or a base paper layer, a label layer, a surface lining paper layer and a surface paper layer, which are compounded in sequence from bottom to top; in the five-layer structure, the finished label is composed of a base paper layer, a bottom lining paper layer, a label layer, a surface lining paper layer and a surface paper layer, which are compounded in sequence from bottom to top.

[0069] It should be noted that the provision of a bottom liner layer can enhance the mechanical properties of the finished label's bottom layer, thereby achieving tensile and puncture resistance. The provision of a bottom liner layer can also enhance the protective effect of the finished label's surface layer. Furthermore, the liner in both the bottom and surface liner layers can be made of a variety of materials, such as polyester, metal foil, and absorbing materials, thereby providing the finished label with additional functionality such as anti-metal interference, high-temperature resistance, and electromagnetic shielding.

[0070] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
