Description

Technical Field

[0001] This invention relates to the field of layered label preparation equipment, and particularly to a composite die-cutting machine. Background Technology

[0002] As an important information storage and transmission carrier, layered electronic tags have seen their manufacturing technology continuously evolve with the development of radio frequency identification (RFID), flexible electronics, and functional composite materials. Early electronic tags mostly adopted single-layer or simple double-layer structures. However, as application scenarios have placed increasing demands on 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 stacking to multi-layer composite systems including substrate layers, 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 under different environments.

[0003] Currently, layered electronic tags are mostly manufactured using lamination and die-cutting processes, integrating multiple layers of materials through layer-by-layer alignment, pressing, and curing. Typical manufacturing equipment includes an unwinding device, guiding mechanism, alignment system, pressing unit, and rewinding module. Existing equipment is usually optimized for one or more fixed-layer structures, such as 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.

[0004] However, existing layered electronic tag manufacturing technologies still have significant limitations, particularly in terms of the number of layers that can be produced and equipment adaptability. Current composite die-cutting equipment can only perform composite die-cutting on labels with four or fewer layers, and cannot adapt to five-layer labels, forcing companies to rely on expensive customized equipment; furthermore, a single composite die-cutting machine can usually only support the production of labels with a fixed number of layers, making it difficult to achieve rapid switching and production of labels with different numbers of layers on a single machine. Summary of the Invention

[0005] The main objective of this invention is to propose a composite die-cutting machine that aims to solve the problems that current composite die-cutting equipment cannot adapt to the preparation of five-layer labels and that a single machine is difficult to switch to produce labels with different numbers of layers.

[0006] To achieve the above objectives, the composite die-cutting machine proposed in this invention is applied to the preparation of layered labels. The composite die-cutting machine includes a frame, a winding assembly, a die-cutting assembly, multiple unwinding assemblies, and four composite assemblies. The multiple unwinding assemblies are all mounted on the frame, and different material strips are wound around the outer periphery of different unwinding assemblies. The material strips include a base paper strip, a bottom backing paper strip, a label strip, a top backing paper strip, and a face paper strip. The winding assembly is mounted on the frame, and the material strips pass through it. The winding assembly is used to transport the base paper strip along a first path. The first path has four composite positions sequentially arranged from upstream to downstream. The winding assembly is also used to independently transport the remaining material strips to convey the bottom backing paper strip to the first... The system includes a lamination station, and / or a label tape conveyed to a second lamination station, and / or a face paper tape conveyed to a third lamination station, and / or a face paper tape conveyed to a fourth lamination station; four lamination components are correspondingly set on the four lamination stations, and each lamination component is independently controlled to start and stop; the lamination components are used to thermally press different material tapes on the corresponding lamination station; wherein, according to the number of layers prepared in the finished label, one to four of the four lamination components are activated; the die-cutting component is set downstream of the fourth lamination station, and the die-cutting component is used to die-cut the laminated tape to obtain the finished label; wherein, the finished label includes at least a base paper layer, a label layer and a face paper layer laminated sequentially from bottom to top.

[0007] In one embodiment, the label tape includes dry inlay tape and wet inlay tape. The dry inlay tape has multiple chip labels, and the wet inlay tape includes at least two adhesive layers and multiple label pieces located between the two adhesive layers. The laminating die-cutting machine further includes a breaking and transferring assembly and a traction mechanism. The breaking and transferring assembly is disposed along a first path between a first laminating position and a second laminating position, and the traction mechanism is disposed along the first path between the breaking and transferring assembly and the second laminating position. When the label tape is a dry inlay tape, the winding assembly is further used to convey the dry inlay tape to the breaking and transferring assembly, which breaks the dry inlay tape into individual chip labels and transfers the chip labels onto the backing tape or the bottom liner tape, so that the label pieces are conveyed to the second laminating position for lamination. When the label tape is a wet inlay tape, the winding assembly is further used to convey the wet inlay tape to the traction mechanism, which traction the wet inlay tape to the second laminating position.

[0008] In one embodiment, the breaking and transferring assembly includes a breaking structure, a transferring hub, and a first driving component. The first driving component is rotatably connected to the breaking structure and the transferring hub. The breaking structure includes a rotating shaft and a blade, with the blade mounted on the rotating shaft and rotating with it. The transferring hub is located below the breaking structure, and its rotation direction is opposite to that of the rotating shaft. One of the left and right sides of the transferring hub is a negative pressure roller, and the other side is a positive pressure roller. The upper boundary between the negative pressure roller and the positive pressure roller is the breaking area, and the lower boundary between them is the transferring area. When the label tape is a dry insert tape, the winding assembly is used to convey the dry insert tape to the breaking area so that the dry insert tape is broken into individual chip labels by the blade and the chip labels are adsorbed onto the surface of the transferring hub. The transferring hub is used to rotate the chip labels to the transferring area and separate them so that the chip labels are adhered to the base paper tape or the bottom backing paper tape.

[0009] In one embodiment, the traction mechanism includes a drive roller, a first pressure roller, and a third drive component. The third drive component is connected to the drive roller in a driving manner. The drive roller and the first pressure roller jointly roll and press the upper and lower sides of the wet insert belt. The third drive component is used to drive the drive roller to rotate so that the wet insert belt is conveyed to the second composite position.

[0010] In one embodiment, the winding assembly includes multiple winding mechanisms, each including a second drive component and a guide roller group. The second drive component is drively connected to the guide roller group, and each winding mechanism is independently controlled to start and stop. The bottom paper tape passes through the guide roller group of the first winding mechanism, which transports the bottom paper tape along a first path. The bottom liner tape passes through the guide roller group of the second winding mechanism, which transports the bottom liner tape to the first bonding position. The label tape passes through the guide roller group of the third winding mechanism, which transports the label tape to the second bonding position. The top liner tape passes through the guide roller group of the fourth winding mechanism, which transports the top liner tape to the third bonding position. The top paper tape passes through the guide roller group of the fifth winding mechanism, which transports the top paper tape to the fourth bonding position.

[0011] In one embodiment, the guide roller group of the first group of feeding mechanisms includes a first sub-roller group, a second sub-roller group, and a third sub-roller group. The first sub-roller group is disposed beside the unwinding assembly for unwinding the bottom paper tape. The second sub-roller group is disposed beside the first composite position. A plurality of guide rollers in the third sub-roller group are respectively disposed beside the breaking and transferring assembly, the traction mechanism, the second composite position, the third composite position, the fourth composite position, and the die-cutting assembly. When the composite assembly at the first composite position is activated, the bottom paper tape passes through the first sub-roller group, the second sub-roller group, and the third sub-roller group in sequence to transport the bottom paper tape along a first path. When the composite assembly at the first composite position is closed, the bottom paper tape passes through the first sub-roller group and the third sub-roller group in sequence to transport the bottom paper tape along a second path. The second path passes through the second composite position, the third composite position, and the fourth composite position in sequence.

[0012] In one embodiment, the composite die-cutting machine further includes four sets of gluing components, which are correspondingly arranged upstream of the four composite positions along the first path. Each set of gluing components is independently controlled to start and stop. The winding assembly is used to transport the bottom paper tape along the first path and sequentially through the four sets of gluing components. The first set of gluing components is used to apply glue to the bottom paper tape to bond it to the bottom backing paper tape / label tape. The second set of gluing components is used to apply glue to the bottom backing paper tape to bond it to the label tape. The third set of gluing components is used to apply glue to the label tape to bond it to the top backing paper tape / face paper tape. The fourth set of gluing components is used to apply glue to the top backing paper tape to bond it to the face paper tape.

[0013] In one embodiment, the composite die-cutting machine further includes a winding assembly disposed downstream of the die-cutting assembly along a first path, the winding assembly being used to wind up the finished label; and / or, the composite assembly includes a hot pressure roller, a second pressure roller, a fourth drive component, and a temperature sensor, the fourth drive component being drively connected to the hot pressure roller, the hot pressure roller having an internal channel for allowing external high-temperature gas or external high-temperature liquid to pass through; the fourth drive component being used to drive the hot pressure roller to apply pressure to the second pressure roller, so that the hot pressure roller and the second pressure roller together perform hot-pressing composite of multiple layers of material strips; the temperature sensor being used to monitor the temperature of the material strip; and / or, the composite die-cutting machine further includes multiple sets of guide rails disposed downstream of multiple sets of unwinding assemblies, the guide rails being used to adjust the degree of deviation between different material strips and the transmission direction.

[0014] In one embodiment, the die-cutting assembly includes a first die-cutting mechanism and a second die-cutting mechanism. The first die-cutting mechanism is located downstream of the fourth composite position, and the second die-cutting mechanism is located downstream of the first die-cutting mechanism. The first and second die-cutting mechanisms are independently controlled to start and stop. The first die-cutting mechanism is used to die-cut the composite strip to be die-cut, so as to cut off the composite layer above the base paper layer, to obtain a finished strip containing a finished label. The second die-cutting mechanism is used to die-cut the composite strip to be die-cut, so as to cut off all composite layers and obtain an independent finished label.

[0015] In one embodiment, the finished label further includes a bottom backing paper layer, and the bottom paper layer, bottom backing paper layer, label layer, and face paper layer are laminated sequentially from bottom to top; and / or, the finished label further includes a face paper layer, and the bottom paper layer, label layer, face paper layer, and face paper layer are laminated sequentially from bottom to top; and / or, the finished label further includes a bottom backing paper layer and a face paper layer, and the bottom paper layer, bottom backing paper layer, label layer, face paper layer, and face paper layer are laminated sequentially from bottom to top.

[0016] The technical solution of this invention adopts a frame-integrated unwinding assembly, a winding assembly, a die-cutting assembly, and four sets of independently controllable composite assemblies. The unwinding and winding assemblies allow the bottom paper tape to pass through four composite positions sequentially along the first path. The winding assembly can independently transmit the corresponding material tape to each composite position according to the number of layers required for the finished label. Thus, the four sets of composite assemblies sequentially and accurately heat-press the bottom paper tape, the bottom backing paper tape, the label tape, the top backing paper tape, and the top paper tape. After die-cutting by the die-cutting assembly, the finished label is finally formed. In the layer-by-layer lamination mode, because the feeding assembly can independently transport each material strip and each lamination assembly can independently control its start and stop, the bottom paper strip is transported along the first path. When only the label strip and face paper strip are conveyed to the corresponding lamination position, and only the lamination assemblies corresponding to the second and fourth lamination positions are activated, a three-layer label containing a bottom paper layer, a label layer, and a face paper layer can be prepared. When only the bottom backing paper strip, label strip, and face paper strip are conveyed to the corresponding lamination position, and the lamination assemblies corresponding to the first, second, and fourth lamination positions are activated, a three-layer label containing a bottom paper layer, a label layer, and a face paper layer can be prepared. This machine produces four-layer labels, consisting of a base paper layer, a bottom backing paper layer, a label layer, and a face paper layer. When only the label tape, face backing paper tape, and face paper tape are conveyed to the corresponding lamination positions, and the lamination components corresponding to the second, third, and fourth lamination positions are activated, a four-layer label consisting of a base paper layer, a label layer, a face backing paper layer, and a face paper layer can be produced. When all material tapes are conveyed to their corresponding lamination positions, and the lamination components corresponding to all four lamination positions are activated, a five-layer label consisting of a base paper layer, a bottom backing paper layer, a label layer, a face backing paper layer, and a face paper layer can be produced. Thus, this lamination die-cutting machine can quickly switch between production of labels with different numbers of layers on a single machine without replacing hardware or re-adjusting, and it can adapt to the production of five-layer labels, solving the problems of existing lamination die-cutting equipment being unable to adapt to the production of five-layer labels and the difficulty of switching between production of labels with different numbers of layers on a single machine.

[0017] Alternatively, a multi-layer co-composite mode can be adopted. This involves using a feeding assembly to transport the base paper strip along the first path and conveying the remaining material strips required for producing the finished label to their corresponding composite positions. However, only the composite component corresponding to the fourth composite position is activated (i.e., only one set of composite components is used), thus completing the hot-pressing composite of multiple material strips at the fourth composite position in one go. Compared to the layer-by-layer composite mode, the multi-layer co-composite mode, because the composite is performed only once throughout the entire process, has a simpler composite control method and a smoother overall composite die-cutting process, making it suitable for composite die-cutting operations with low precision requirements. In contrast, the layer-by-layer composite mode, because it can perform composite immediately after each material strip is transported to its corresponding composite position, is less prone to relative displacement between the composited layers during transport and die-cutting after composite, resulting in higher relative positioning accuracy. This is suitable for composite die-cutting operations with high precision requirements, producing high-precision finished labels.

[0018] Furthermore, this composite die-cutting machine integrates the unwinding assembly, the feeding assembly, the laminating assembly, and the die-cutting assembly, enabling the material strip to complete the entire process of unwinding, transporting, laminating, and die-cutting within the machine frame. This reduces the number of transfers and path lengths required by traditional multi-equipment series connection, lowers energy consumption and space occupation, and improves production efficiency and equipment adaptability.

[0044] As an important information storage and transmission carrier, layered electronic tags have seen their manufacturing technology continuously evolve with the development of radio frequency identification (RFID), flexible electronics, and functional composite materials. Early electronic tags mostly adopted single-layer or simple double-layer structures. However, as application scenarios have placed increasing demands on 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 stacking to multi-layer composite systems including substrate layers, 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 under different environments.

[0045] Currently, layered electronic tags are mostly manufactured using lamination and die-cutting processes, integrating multiple layers of materials through layer-by-layer alignment, pressing, and curing. Typical manufacturing equipment includes an unwinding device, guiding mechanism, alignment system, pressing unit, and rewinding module. Existing equipment is usually optimized for one or more fixed-layer structures, such as 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.

[0046] However, existing layered electronic tag manufacturing technologies still have significant limitations, particularly in terms of the number of layers that can be produced and equipment adaptability. Current composite die-cutting equipment can only perform composite die-cutting on labels with four or fewer layers, and cannot adapt to five-layer labels, forcing companies to rely on expensive customized equipment; furthermore, a single composite die-cutting machine can usually only support the production of labels with a fixed number of layers, making it difficult to achieve rapid switching and production of labels with different numbers of layers on a single machine.

[0047] To address the above problems, this invention proposes a composite die-cutting machine.

[0048] Please see Figure 1In one embodiment of the present invention, the composite die-cutting machine is used to prepare layered labels. The composite die-cutting machine includes a frame 1200, a winding assembly 1000, a die-cutting assembly 2000, multiple unwinding assemblies 3000, and four composite assemblies 4000. The multiple unwinding assemblies 3000 are all mounted on the frame, and different material strips are wound around the outer periphery of different unwinding assemblies 3000. The material strips include a base paper strip, a bottom backing paper strip, a label strip, a top backing paper strip, and a face paper strip. The winding assembly 1000 is mounted on the frame, and the material strips pass through it. The winding assembly 1000 is used to transport the base paper strip along a first path. The first path has four composite positions sequentially arranged from upstream to downstream. The winding assembly 1000 is also used to independently transport the remaining material strips to convey the bottom backing paper strip to the first composite position. The system includes four composite units 4000, each set of which is independently controlled to start and stop. The composite unit 4000 is used to thermally press different material strips on the corresponding composite units. The number of composite units 4000 is determined by the number of layers required for the finished label. A die-cutting unit 2000 is located downstream of the fourth composite unit 5400. The die-cutting unit 2000 is used to die-cut the laminated strips to obtain the finished label. The finished label includes at least a base paper layer, a label layer, and a face paper layer laminated sequentially from bottom to top.

[0049] The technical solution of this invention employs a frame-integrated unwinding assembly 3000, a winding assembly 1000, a die-cutting assembly 2000, and four independently controllable composite assemblies 4000. The unwinding assembly 3000 and the winding assembly 1000 allow the base paper tape to sequentially pass through four composite positions along a first path. The winding assembly 1000 can independently transmit the corresponding material tape to each composite position according to the layer requirements of the finished label. Thus, the four composite assemblies 4000 sequentially and precisely heat-press the base paper tape with the bottom backing paper tape, the label tape, the top backing paper tape, and the top paper tape. After die-cutting by the die-cutting assembly 2000, the final product label is formed. In the layered lamination mode, since the roll feeding assembly 1000 can independently transport each material strip, and each lamination assembly 4000 can be independently controlled to start and stop, the bottom paper strip is transported along the first path. When only the label strip and the face paper strip are conveyed to the corresponding lamination position, and only the lamination assembly 4000 corresponding to the second lamination position 5200 and the fourth lamination position 5400 is activated (e.g. Figure 2 As shown), a three-layer label comprising a backing paper layer, a label layer, and a face paper layer can be prepared; when only the bottom backing paper tape, label tape, and face paper tape are conveyed 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 activated (as shown) Figure 3 As shown), a four-layer label comprising a base paper layer, a bottom backing paper layer, a label layer, and a face paper layer can be prepared; when only the label tape, face backing paper tape, and face paper tape are conveyed 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 activated (as shown) Figure 4 As shown), a four-layer label consisting of a base paper layer, a label layer, a top liner paper layer, and a face paper layer can be prepared; when each material strip is conveyed to the corresponding lamination position, and all four lamination positions are activated with the corresponding lamination components 4000 (as shown), Figure 1 As shown, this composite die-cutting machine can produce five-layer labels, including a base paper layer, a bottom backing paper layer, a label layer, a top backing paper layer, and a face paper layer. Thus, this machine can quickly switch between producing labels with different numbers of layers on a single unit without replacing hardware or re-adjusting, and it can adapt to the production of five-layer labels, solving the problems of existing composite die-cutting equipment being unable to adapt to the production of five-layer labels and the difficulty of switching between producing labels with different numbers of layers on a single unit.

[0050] Alternatively, a multi-layer co-composite mode can be adopted. This involves using the feeding assembly 1000 to transport the base paper strip along the first path and conveying the remaining material strips required for preparing the finished label to the corresponding composite positions. However, only the composite component corresponding to the fourth composite position 5400 is activated (i.e., only one set of composite components is used), thus completing the hot-pressing composite of multiple material strips at the fourth composite position 5400 in one go. Compared to the layer-by-layer composite mode, the multi-layer co-composite mode, because the composite is performed only once throughout the entire process, has a simpler composite control method and a smoother overall composite die-cutting process, making it suitable for composite die-cutting operations with low precision requirements. In contrast, the layer-by-layer composite mode, because it can perform composite immediately after each material strip is transported to the corresponding composite position, is less prone to relative displacement between the composited material strips during post-composite transport and die-cutting processes, resulting in higher relative positioning accuracy. This is suitable for composite die-cutting operations with high precision requirements, producing high-precision finished labels.

[0051] Furthermore, this composite die-cutting machine integrates the unwinding assembly 3000, the feeding assembly 1000, the composite assembly 4000, and the die-cutting assembly 2000, enabling the material strip to complete the entire process of unwinding, transporting, composite, and die-cutting within the machine frame. This reduces the number of transfers and path lengths required by traditional multi-equipment series connection, lowers energy consumption and space occupation, and improves production efficiency and equipment adaptability.

[0052] In addition, the unwinding assembly 3000 may include basic drive devices, unwinding shafts and other components. The drive device may be configured as a servo motor or other drive components. The drive device is connected to the unwinding shaft for transmission, so that the unwinding shaft is driven to rotate by the drive device, thereby unwinding the material belt wound on the unwinding shaft.

[0053] Furthermore, the winding assembly 1000 may include multiple winding mechanisms, each corresponding to transport a type of material strip. One winding mechanism transports the base paper strip along a first path, while the other winding mechanisms independently transport the remaining four material strips from their respective unwinding assemblies 3000 to their corresponding lamination positions. For example, when preparing a three-layer finished label, one winding mechanism transports the base paper strip along the first path, another winding mechanism conveys the label strip to the second lamination position, and yet another winding mechanism conveys the face paper strip to the fourth lamination position. The remaining winding mechanisms can be shut down. The winding assembly 1000 may include components such as guide rollers and a drive device, thereby using the drive device to drive the guide rollers, causing the material strips passing over the surface of the guide rollers to move along a specific path.

[0054] The composite component 4000 may have a hot press roller and pressure-bearing support components such as a pressure plate / pressure roller that cooperate with the hot press roller. The drive device of the composite component 4000 applies pressure to the hot press roller, causing the hot press roller to press against the support components, thereby hot-pressing and bonding the material strip passing between the hot press roller and the support components. The drive device of the composite component 4000 may be one of various drive components such as a motor, cylinder, or hydraulic cylinder, which will not be described in detail here.

[0055] The die-cutting assembly 2000 can employ a scheme where a drive unit and a die-cutting blade work together. The drive unit is connected to the die-cutting blade via a transmission connection, thereby driving the die-cutting blade to die-cut the strip to be die-cut. Alternatively, the die-cutting assembly 2000 can employ a scheme where a moving device works in conjunction with a laser generator. The laser generator emits a laser beam to cut the strip to be die-cut, and the moving device moves the laser generator, thereby cutting the strip to be die-cut into the desired shape and obtaining the finished label. Of course, other die-cutting methods can also be used, which will not be elaborated here.

[0056] Alternatively, as an optional implementation, the composite die-cutting machine may also include a control module. The control module may be an electronic device such as a computer, microcontroller unit (MCU), or programmable logic controller (PLC). The control module may be communicatively connected to the winding feeding assembly 1000, the die-cutting assembly 2000, multiple unwinding assemblies 3000, and four composite assemblies 4000, thereby controlling the start and stop of each component and related operating parameters, such as adjusting the winding feeding speed of the winding feeding assembly 1000, adjusting the temperature of the composite assembly 4000 during the hot-pressing composite process, applying pressure, etc., so as to uniformly regulate each component on the control module.

[0057] Please see Figure 1 and Figure 5In embodiments of the present invention, the label tape types include dry inlay tape and wet inlay tape. The dry inlay tape has multiple chip labels, and the wet inlay tape includes at least two adhesive layers and multiple label pieces located between the two adhesive layers. The composite die-cutting machine further includes a breaking and transferring assembly 6000 and a traction mechanism 7000. The breaking and transferring assembly 6000 is disposed along a first path between the first composite position 5100 and the second composite position 5200, and the traction mechanism 7000 is disposed along the first path between the breaking and transferring assembly 6000 and the second composite position 5200. When When the label tape is a dry inlay tape, the winding assembly 1000 is also used to convey the dry inlay tape to the breaking and transferring assembly 6000, which breaks the dry inlay tape into individual chip labels and transfers the chip labels onto the backing tape or bottom liner tape, so that the label sheet is conveyed to the second composite position 5200 for composite; when the label tape is a wet inlay tape, the winding assembly 1000 is also used to convey the wet inlay tape to the traction mechanism 7000, which traction mechanism 7000 is used to traction the wet inlay tape onto the second composite position 5200.

[0058] It should be noted that the inlay in this embodiment refers to what is commonly known in the industry as an Inlay. An electronic tag Inlay is a pre-laminated product consisting of multiple layers of plastic sheets, chips, and coil layers, typically composed of two or three layers. It can also be understood as an unencapsulated semi-finished product of an RFID tag. Different types of electronic tags can be made from Inlays through different encapsulation methods. Inlays are divided into two types: dry Inlay and wet Inlay, corresponding to the dry inlay tape and wet inlay tape in this embodiment, respectively. Dry Inlays generally use polyester substrates, while wet Inlays typically use release paper substrates. Wet Inlays usually have an adhesive layer coated on the surface of the chip layer containing the chip and antenna, which is then attached to the release paper. This adhesive layer is usually made of hot melt adhesive. Since the wet insert has its own adhesive layer, after the release paper is peeled off the wet insert, the wet insert, containing only the adhesive layer and the chip layer, is transported to the lamination position and the adhesive layer can be melted by hot pressing, thus allowing the wet insert to adhere to the corresponding material strip. Therefore, the operation of applying adhesive to the corresponding material strip or wet insert before lamination can be eliminated. In this embodiment, the release film has been peeled off before the wet insert is transported to the traction mechanism 7000, so the wet insert can consist of only two adhesive layers and multiple label pieces located between the two adhesive layers.

[0059] In this embodiment, by adding a cutting and transferring assembly 6000 and a traction mechanism 7000 to the frame, and having the cutting and transferring assembly 6000 and the traction mechanism 7000 respectively process dry insert tape and wet insert tape, the composite die-cutting machine can adapt to different label tape types; when the label tape is a dry insert tape (e.g. Figure 1As shown), the roll feeding assembly 1000 feeds the dry insert tape to the breaking and transferring assembly 6000. The breaking and transferring assembly 6000 first precisely breaks the continuous tape into individual chip labels, and then transfers the chip label onto the base paper tape or bottom backing paper tape. Subsequently, the roll feeding assembly 1000 continues to transport it to the second lamination station 5200, thereby ensuring the accurate positioning of the chip label with the base paper layer or bottom backing paper layer in subsequent lamination processes, avoiding chip spacing errors and interlayer misalignment caused by continuous transport of the entire roll of dry insert tape; when the label tape is a wet insert tape (such as... Figure 5 As shown, the feeding assembly 1000 delivers the wet insert tape to the traction mechanism 7000. The traction mechanism 7000 directly pulls the wet insert tape, which contains two adhesive layers and multiple label sheets, to the second lamination position 5200. Continuous lamination can be achieved without interruption, effectively utilizing the adhesive layer of the wet insert tape to heat-press the backing paper layer or bottom liner paper layer in one step, reducing additional gluing processes and minimizing adhesive volume fluctuations. This lamination die-cutting machine can achieve lamination and die-cutting of both dry and wet insert label tapes on a single machine. At the same time, through the 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 lamination position are ensured, further improving the yield and performance consistency of the finished labels.

[0060] The operator can adjust the feeding assembly 1000 to transport the label tape to either the breaking and transferring assembly 6000 or the traction mechanism 7000. For example, the feeding assembly 1000 may include multiple guide rollers through which the label tape passes. The operator can adjust the direction of the label tape around the guide rollers. For instance, if the breaking and transferring assembly 6000 and the traction mechanism 7000 are located to the left and right of the first guide roller, respectively, by adjusting the winding direction of the label tape, when the unwound label tape is a dry insert tape, the operator can transport the dry insert tape around the first guide roller to the left, so that the breaking and transferring assembly 6000 can receive the dry insert tape; when the unwound label tape is a wet insert tape, the operator can transport the wet insert tape around the first guide roller to the right, so that the traction mechanism 7000 can receive the wet insert tape. In this way, the composite die-cutting machine can be adapted to dry insert tape and wet insert tape, that is, to switch between dry insert and wet insert modes.

[0061] Furthermore, by combining the start-stop control of the aforementioned winding assembly 1000 and the four sets of composite assemblies 4000, and the corresponding activation of the interruption transfer assembly 6000 and the traction mechanism 7000 in this embodiment, the number of layers in the finished label preparation and the switching between dry and wet inlays can be achieved. Taking the conversion from preparing a three-layer finished label with a dry inlay tape to preparing a five-layer finished label with a wet inlay tape as an example, the following explanation is provided: When it is necessary to prepare a three-layer finished label, and the label tape is a dry inlay tape (dry inlay) (e.g.) Figure 2As shown), the backing paper tape can be transported along the first path using the winding assembly 1000, and the dry insert tape can be transferred to the breaking and transferring assembly 6000 using the winding assembly 1000, so that the dry insert tape is broken and transferred onto the backing paper tape and then transferred to the second composite position; the face paper tape is also transferred to the fourth composite position using the winding assembly 1000; the composite assembly 4000 corresponding to the second composite position 5200 and the fourth composite position 5400 is activated, so that the dry insert tape and the backing paper tape are composited at the second composite position, and the composited dry insert layer and the backing paper layer are composited with the face paper tape at the fourth composite position. When it is necessary to convert to the preparation of a five-layer finished label with a wet insert tape (wet inlay) (such as... Figure 5 As shown, the operator can replace the dry insert tape in the unwinding assembly 3000 corresponding to the label tape with a wet insert tape to unwind the wet insert tape. The operator also needs to adjust the direction of the wet insert tape around the guide roller in the feeding assembly 1000 (as mentioned above, the label tape passing around the first guide roller changes from being transported to being transported to the right), so that the traction mechanism 7000 receives the wet insert tape. Then, all unwinding assemblies 3000, feeding assemblies 1000, and traction mechanisms 7000 can be started, so that the bottom paper tape is transported along the first path, and the remaining material tapes are transported to the corresponding lamination positions. Among them, the wet insert tape passes through the feeding assembly 1000 and the traction mechanism 7000 in sequence and is transported to the second lamination position. At the same time, all four lamination assemblies are also started, so as to achieve layer-by-layer lamination at each lamination position. In this way, the adjustment of the number of layers of the finished label preparation and the switching between dry and wet inlay modes can be completed.

[0062] In other cases, the above operating procedures can be referred to, and Figures 1 to 8 The diagram illustrates the activation of the corresponding winding assembly 1000, four composite assemblies 4000, cutting and transferring assembly 6000, and traction mechanism 7000. When preparing five-layer finished labels, and the label tape is a dry inlay tape, refer to... Figure 1 When preparing a four-layer finished label including a bottom backing paper layer, and the label tape is a dry inlay tape, please refer to the following: Figure 3 When preparing a four-layer finished label including a face layer and a backing paper layer, and the label tape is a dry inlay tape, please refer to the following: Figure 4 When a three-layer finished label needs to be prepared, and the label tape is a wet inlay tape, please refer to the following: Figure 6 When preparing a four-layer finished label including a bottom backing paper layer, and the label tape is a wet-embedded tape, refer to the following: Figure 7 When preparing a four-layer finished label including a face layer and a backing paper layer, and the label tape is a wet-embedded tape, refer to the following: Figure 8 .

[0063] In addition, the composite die-cutting machine may also include a stripping mechanism, which is located next to the feeding assembly 1000. After the feeding assembly 1000 releases the material belt, the peeling blade on the stripping mechanism is used to peel off the protective layers such as release film, polyester film, and release paper from the material belt, leaving behind and transporting the required material. A waste roll collection mechanism may also be provided next to the stripping mechanism. The waste roll collection mechanism is used to collect the aforementioned protective film. The structure of the waste roll collection mechanism can refer to that of the unwinding assembly 3000, and will not be described in detail here.

[0064] Please see Figure 1 In an embodiment of the present invention, the breaking and transferring assembly 6000 includes a breaking structure (not shown in the figure), a transferring 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 breaking structure and the transferring hub. The breaking structure includes a rotating shaft and a blade. The blade is disposed on the rotating shaft and rotates with the rotating shaft. The transferring hub is located below the breaking structure, and the rotation direction of the transferring hub is opposite to the rotation direction of the rotating shaft. One of the left and right sides of the transferring hub is a negative pressure wheel. The other side of the right side is the positive pressure roller section. The upper boundary between the negative pressure roller section and the positive pressure roller section is the breaking area, and the lower boundary between the negative pressure roller section and the positive pressure roller section is the transfer area. When the label tape is a dry insert tape, the winding assembly 1000 is used to convey the dry insert tape to the breaking area so that the dry insert tape is broken into individual chip labels by the blade and the chip labels are adsorbed onto the surface of the transfer hub. The transfer hub is used to rotate the chip labels to the transfer area and separate the chip labels so that the chip labels are adhered to the backing paper tape or the bottom backing paper tape.

[0065] In this embodiment, the cutting and transferring assembly 6000 is configured to include a cutting structure, a transfer hub, and a first driving component. The cutting structure's rotating shaft rotates with a blade, while the transfer hub rotates in the opposite direction. The left and right sides of the transfer hub form a negative pressure wheel and a positive pressure wheel, respectively. The upper boundary between the negative and positive pressure wheels constitutes the cutting area, and the lower boundary constitutes the transfer area. Thus, when the dry inlay tape enters the cutting area, the rotating blade precisely cuts the continuous dry inlay tape into individual chip labels. The vacuum suction force generated by the negative pressure wheel at the moment of cutting immediately and stably adsorbs the chip labels onto the surface of the transfer hub. This design avoids secondary displacement or scattering of the chip label after cutting. As the chip label continues to rotate with the transfer hub to the transfer area, the positive pressure roller releases positive pressure airflow, pushing the chip label away from the transfer hub surface while the vacuum adsorption is released, and precisely adhering it to the bottom paper tape or the bottom backing paper tape. Since the blade and the transfer hub rotate in opposite directions, the cutting and adsorption actions are completed instantaneously in the cutting area, which improves the cutting efficiency and reduces the stretching deformation of the dry inlay tape. At the same time, the continuous switching between negative and positive pressure enables the non-destructive transfer of the chip label, avoiding chip damage or adhesive layer contamination caused by traditional mechanical gripping.

[0066] The transfer hub has multiple ventilation holes on its outer periphery and two chambers on the left and right sides inside. The two chambers are isolated from each other, and the ventilation holes are connected to the corresponding chambers on their respective sides. One chamber can be connected to the air outlet device, and the other chamber can be connected to the suction device, thereby creating a positive pressure air outlet effect for the ventilation hole corresponding to one chamber and a negative pressure suction effect for the ventilation hole corresponding to the other chamber.

[0067] 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 drive component (not shown in the figure). The third drive component is connected to the transmission roller in a transmission manner. The transmission roller and the first pressure roller jointly roll and press the upper and lower sides of the wet insert belt. The third drive component is used to drive the transmission roller to rotate so that the wet insert belt is conveyed to the second composite position 5200.

[0068] In this embodiment, the traction mechanism 7000 includes a transmission roller, a first pressure roller, and a third drive component. The third drive component directly drives the transmission roller to rotate, so that the transmission roller and the first pressure roller together synchronously roll the wet insert tape on both sides. This applies a stable and continuous forward traction force before the wet insert tape enters the second composite position 5200. Since the wet insert tape does not need to be broken and transferred, it can be 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.

[0069] Please see Figure 1 In an embodiment of the present invention, the winding assembly 1000 includes multiple winding mechanisms, each of which includes a second driving component (not shown in the figure) and a guide roller group. The second driving component is drively connected to the guide roller group, and each winding mechanism is independently controlled to start and stop. The bottom paper tape passes through the guide roller group of the first winding mechanism 1010, which is used to transport the bottom paper tape along a first path. The bottom liner paper tape passes through the guide roller group of the second winding mechanism 1020, which is used to transport the bottom liner paper. The label tape is transported to the first composite position 5100; the label tape passes through the guide roller group of the third winding mechanism 1030, which is used to transport the label tape to the second composite position 5200; the face sheet tape passes through the guide roller group of the fourth winding mechanism 1040, which is used to transport the face sheet tape to the third composite position 5300; the face paper tape passes through the guide roller group of the fifth winding mechanism 1050, which is used to transport the face paper tape to the fourth composite position 5400.

[0070] In this embodiment, by setting the winding assembly 1000 as a winding mechanism including a second drive component and a guide roller group with five independently start-stop units, and by independently driving and guiding the bottom paper tape, bottom liner tape, label tape, top liner tape, and top paper tape by the first winding mechanism 1010, the second winding mechanism 1020, the third winding mechanism 1030, the fourth winding mechanism 1040, and the fifth winding mechanism 1050, respectively, individual closed-loop control of tension, speed, and position is achieved before each material tape enters the corresponding composite position, avoiding interlayer misalignment, wrinkles, or tensile deformation caused by speed difference or uneven tension when multiple layers are unwound simultaneously. 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 activated. The bottom liner paper tape and the top liner paper tape remain stationary, reducing ineffective material feeding and material waste. When preparing a four-layer label, the second group of winding mechanisms 1020 or the fourth group of winding mechanisms 1040 are activated to quickly insert the bottom liner paper layer between the bottom paper layer and the label layer, or to insert the top liner paper layer between the label layer and the top paper layer. When preparing a five-layer label, all five groups of winding mechanisms are activated. Each guide roller group operates synchronously at a preset speed under the drive of an independent second drive component, ensuring that the five layers of material are accurately stacked sequentially at the four composite positions. Since each group of feeding mechanisms can be started and stopped independently and the path of the guide roller group is fixed, operators only need to switch the start and stop states of the corresponding feeding mechanism to complete the change of labels with different layers. There is no need to readjust the mechanical structure, which significantly shortens the changeover time and reduces the complexity of operation. At the same time, it ensures the tension stability and alignment accuracy of each layer of material under high-speed operation, and improves the yield rate and production flexibility of finished labels.

[0071] In one optional implementation, the composite die-cutting machine may further include multiple sets of vision inspection components. The control module is communicatively connected to these vision inspection components and multiple winding mechanisms. The vision inspection components can be positioned around the guide rollers of the winding mechanisms. These components detect the tension of the material strip, thereby determining the tension it experiences. The control module adjusts parameters such as the rotation speed of the winding mechanism at the corresponding position based on the detected tension, thus preventing the material strip from breaking due to excessive tension. This implementation, through the cooperation of the control module and the visual feedback from the vision inspection components, achieves adaptive adjustment of operating parameters such as the rotation speed of the winding mechanism, effectively improving the automation level of the composite die-cutting machine and reducing the degree of manual intervention and errors that may arise from manual operation. In addition, some visual inspection components can be installed at each of the compositing and die-cutting components 2000. These components can detect the compositing and die-cutting status of each material strip and feed the results back to the control module. The control module can then use a pre-stored detection algorithm to determine whether the compositing and die-cutting status of the material strip is acceptable. If it is unacceptable, a warning message can be issued to prompt the operator to intervene, thus allowing for timely intervention on non-conforming products during the compositing and die-cutting process. The detection algorithm can be a defect detection algorithm, which can be based on neural network models such as YOLO and CNN, and trained and tested using defect datasets collected during the compositing and die-cutting processes. Other detection methods can also be used, which will not be elaborated upon here.

[0072] Please see Figure 1 and Figure 2 In an embodiment of the present invention, the guide roller group of the first group of winding 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 disposed beside the unwinding assembly 3000 for unwinding the bottom paper tape; the second sub-roller group 1012 is disposed beside the first composite position 5100; and a plurality of guide rollers in the third sub-roller group 1013 are respectively disposed in the breaking and transferring assembly 6000, the traction mechanism 7000, the second composite position 5200, the third composite position 5300, the fourth composite position 5400, and the die-cutting assembly 20. On the side of 00; when the composite assembly 4000 located at the first composite position 5100 is activated, the bottom paper tape is used to pass sequentially through the first sub-roller group 1011, the second sub-roller group 1012 and the third sub-roller group 1013 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 sequentially through the first sub-roller group 1011 and the third sub-roller group 1013 so that the bottom paper tape is transported along the second path; the second path passes sequentially through the second composite position 5200, the third composite position 5300 and the fourth composite position 5400.

[0073] In this embodiment, by arranging a first sub-roller group 1011, a second sub-roller group 1012, and a third sub-roller group 1013 within the guide roller group of the first winding mechanism 1010, and positioning the first sub-roller group 1011 adjacent to the unwinding assembly 3000 corresponding to the bottom paper tape, the second sub-roller group 1012 adjacent to the first composite position 5100, and the third sub-roller group 1013 spanning across the break-and-adhesion assembly 6000, the traction mechanism 7000, the second composite position 5200, the third composite position 5300, the fourth composite position 5400, and the die-cutting assembly 2000, when it is necessary to composite the bottom backing paper tape and the bottom paper tape (i.e., when the composite assembly 4000 of the first composite position 5100 is activated), the bottom paper tape can sequentially pass through the first sub-roller group 1011, the second sub-roller group 1012, and the third sub-roller group 1013, and move along the first path, so that the bottom paper tape can be composited with the bottom backing paper tape and then participate in the composite of subsequent material tapes. This situation is as follows. Figure 1 As shown; when the composite bottom liner tape and bottom paper tape are not required (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, bypassing 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. This situation is as follows: Figure 2 As shown.

[0074] The switching between moving the bottom paper tape along the first path and moving it along the second path can be done by the operator. The operator can change the conveying path of the bottom paper tape by winding the bottom paper tape around different sub-roller groups accordingly.

[0075] Please see Figure 1 In an embodiment of the present invention, the composite die-cutting machine further includes four sets of gluing components, which are correspondingly arranged upstream of the four composite positions along the first path. Each set of gluing components is independently controlled to start and stop. The winding assembly 1000 is used to transport the bottom paper tape along the first path and sequentially pass through the four sets of gluing components. The first set of gluing components 8100 is used to apply glue to the bottom paper tape to bond it to the bottom backing paper tape / label tape. The second set of gluing components 8200 is used to apply glue to the bottom backing paper tape to bond it to the label tape. The third set of gluing components 8300 is used to apply glue to the label tape to bond it to the top backing paper tape / face paper tape. The fourth set of gluing components 8400 is used to apply glue to the top backing paper tape to bond it to the face paper tape.

[0076] In this embodiment, four independently startable and stopable glue coating components are respectively set upstream of the four composite positions along the first path, and the feeding component 1000 drives the bottom paper tape to pass through the four glue coating components sequentially along the first path. This allows for selective activation of the corresponding glue coating components based on the label layer requirements and whether each material tape has pre-applied composite adhesive. When any material tape has pre-applied composite adhesive, the corresponding glue coating component does not need to be activated, and the pre-applied composite adhesive can be used directly for lamination. For other material tapes that are not lamination-compatible with the material tape and have not been pre-applied adhesive, the corresponding glue coating components can be activated to apply adhesive to the remaining material tapes. When none of the material tapes have pre-applied composite adhesive, only the first glue coating component 8100 and the third glue coating component 8300 need to be activated when preparing a three-layer label. The bottom paper tape completes the application of composite adhesive between the bottom paper layer and the label layer at the first glue coating component 8100, and the label tape completes the application at the third glue coating component. At position 8300, the adhesive is applied to the label layer and the face paper layer. The bottom and top backing paper tapes do not output adhesive because their corresponding adhesive application components are closed, avoiding adhesive waste and subsequent cleaning. When preparing a four-layer label, the first adhesive application component 8100, the second adhesive application component 8200, and the third adhesive application component 8300 are activated, or the first adhesive application component 8100, the third adhesive application component 8300, and the fourth adhesive application component 8400 are activated, thereby applying adhesive to the bottom paper tape and the bottom backing paper. The tape and label tape are coated with composite adhesive to complete the bonding of the base paper layer, the bottom liner paper layer, the label layer, and the face paper layer. Alternatively, the base paper tape, label tape, and face liner paper tape are coated with composite adhesive to complete the bonding of the base paper layer, the label layer, the face liner paper layer, and the face paper layer. When preparing a five-layer label, all four sets of adhesive application components are activated, and the base paper tape, the bottom liner paper tape, the label tape, and the face liner paper tape are coated with composite adhesive in sequence to achieve a complete composite of the base paper layer, the bottom liner paper layer, the label layer, the face liner paper layer, and the face paper layer.

[0077] The adhesive application assembly may include a drive component, a storage container, a push rod, and a moving device. The storage container has a cavity connected to the outside via a nozzle. The moving device is driven by the storage container to move it. The push rod is located inside the storage container and is used to push the composite adhesive inside the container outwards. The drive component is driven by the push rod to push it. This allows the adhesive application assembly to apply adhesive to various material strips. When adhesive application is needed, the moving device moves the storage container, causing the nozzle of the storage container to contact the corresponding material strip, or shortening the distance between the nozzle and the material strip to a preset adhesive application distance. The drive component pushes the push rod, causing the composite adhesive inside the storage container to flow out along the nozzle and adhere to the material strip. After adhesive application, the moving device moves the storage container in the opposite direction to avoid contact between the nozzle and the material strip. The moving device may be a single-axis moving platform, guided by guide rails and moved using a screw and nut transmission method; the specific structure can refer to existing single-axis moving platforms. The drive component may be a cylinder, motor, etc., which will not be described in detail here.

[0078] Please see Figure 1 In an embodiment of the present invention, the composite die-cutting machine further includes a winding assembly 9000, which is disposed downstream of the die-cutting assembly 2000 along a first path. The winding assembly 9000 is used to wind up the finished label. And / or, the composite assembly 4000 includes a hot press roller, a second pressure roller, a fourth drive component (not shown in the figure), and a temperature sensor (not shown in the figure). The fourth drive component is connected to the hot press roller in a driving connection. The hot press roller has a channel inside for allowing external high-temperature gas or external high-temperature liquid to pass through. The fourth drive component is used to drive the hot press roller to apply pressure to the second pressure roller, so that the hot press roller and the second pressure roller together perform hot pressing composite on the multi-layer material strip. The temperature sensor is used to monitor the temperature of the material strip. And / or, the composite die-cutting machine further includes multiple sets of guide rails 1100, which are correspondingly disposed downstream of multiple sets of unwinding assemblies 3000. The guide rails 1100 are used to adjust the degree of deviation between different material strips and the transmission direction.

[0079] In this embodiment, by setting a winding assembly 9000 downstream of the die-cutting assembly 2000 along the first path, the finished label can be continuously wound up after die-cutting, avoiding creases and contamination caused by manual handling and reducing manual winding costs. By designing the composite assembly 4000 as an integrated structure of a hot press roller, a second press roller, a fourth drive component, and a temperature sensor, and by setting a channel inside the hot press roller for the flow of high-temperature gas or liquid, when the fourth drive component drives the hot press roller to press against the second press roller, heat is quickly and evenly transferred to the multi-layer material strip through the roller surface, achieving instantaneous heating and constant temperature maintenance. The temperature sensor can provide feedback on the temperature of the material strip, so as to adjust the temperature of the gas or liquid introduced according to the temperature of the material strip, thereby ensuring that the material strip can reach the expected composite temperature. By arranging guide rails 1100 downstream of multiple sets of unwinding assemblies 3000, each guide rail 1100 independently detects and corrects the offset of the corresponding material strip relative to the transmission direction in real time, thereby improving the interlayer alignment accuracy.

[0080] The web guide 1100, also known as a web guiding controller, is an automated device used in industries such as printing and packaging, papermaking, and film production. It is primarily used to correct material misalignment during roll material production. Various models of the web guide 1100 are currently available on the market, such as the Fife, D-ARISE, and SG series. The appropriate model and purchase can be selected based on actual needs. The specific structure of the web guide 1100 will not be elaborated upon here.

[0081] Please see 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 located downstream of the fourth composite position 5400, and the second die-cutting mechanism 2200 is located 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 composite strip to be die-cut to cut off the composite layer above the base paper layer to obtain a finished strip containing a finished label. The second die-cutting mechanism 2200 is used to die-cut the composite strip to be die-cut to cut off all composite layers and obtain an independent finished label.

[0082] In this embodiment, by sequentially arranging the first die-cutting mechanism 2100 and the second die-cutting mechanism 2200, which can be started and stopped independently, along the first path downstream of the fourth composite position 5400, the composite strip to be die-cut can complete both half-cut and full-cut die-cutting requirements within the same frame: when only the base paper layer needs to be retained as the substrate (i.e., half-cut), starting the first die-cutting mechanism 2100 can cut off all composite layers above the base paper layer while keeping the base paper intact, forming a continuous finished strip containing the finished label, which is convenient for subsequent roll shipment or secondary slitting; when an independent single finished label is required (i.e., full-cut), the first die-cutting mechanism 2100 is turned off and the second die-cutting mechanism 2200 is started, which can cut off all composite layers at once, directly outputting an independent finished label without waste edges or connecting points, eliminating the offline secondary die-cutting process. Operators can quickly switch between half-cut and full-cut modes without stopping the machine by correspondingly starting and stopping the first die-cutting mechanism 2100 and the second die-cutting mechanism 2200, improving the convenience of switching.

[0083] In one optional implementation, the first die-cutting mechanism 2100 includes a fifth driving component, a first mounting structure, and a flat blade. The flat blade is detachably mounted on the first mounting structure, and the fifth driving component is drive-connected to the first mounting structure. The second die-cutting mechanism 2200 includes a sixth driving component, a second mounting structure, and an arc-shaped cutting edge. A circular blade is detachably mounted on the second mounting structure, and the sixth driving component is drive-connected to the second mounting structure. The flat blade can be understood as a flat plate with a die-cutting mold mounted on it. The flat blade moves vertically downwards, impacting the strip to be die-cut below, thereby cutting all composite layers and obtaining individual finished labels. The circular blade can be understood as a cutting roller with an arc-shaped die-cutting mold rolling against a smooth anvil roller, where the material is rolled and sheared as it passes between the two rollers.
