Description

Technical Field

[0001] This invention relates to the field of transfer film technology, and in particular to a composite transfer film forming system and method. Background Technology

[0002] In short, transfer film is a special thin film pre-loaded with patterns or functional coatings. It is not the final product itself, but rather a means to transfer the coating completely and firmly to the surface of objects of various shapes and materials. This allows for efficient and high-quality decoration on industrial products, thereby upgrading their appearance and performance from ordinary to exquisite and from single to multifunctional. Transfer film technology is an indispensable surface treatment process in modern manufacturing, closely linking two-dimensional design with three-dimensional finished products and decorative aesthetics with practical functions. It greatly enhances the added value and market competitiveness of products and continues to expand with the advancement of materials.

[0003] Patent document CN222713176U discloses a wear-resistant heat transfer lettering film, belonging to the field of thin film technology. It sequentially includes a release film layer, a light-transmitting connecting layer, an adhesive layer, a support layer, a hot melt adhesive layer, and a second release film layer. A printing layer is disposed on the side of the light-transmitting connecting layer facing the adhesive layer. The support layer forms several air channels perpendicular to the thickness direction of the lettering film and several ventilation openings aligned with the thickness direction of the lettering film. The ventilation openings communicate with the air channels, and the hot melt adhesive layer is disposed along the edges of the ventilation openings. This wear-resistant heat transfer lettering film allows for air absorption through clothing when surrounding air flows, thus accelerating breathability and reducing the airtightness of areas covered by the lettering film, ensuring comfort.

[0004] However, in actual production and use, the inventors found that the existing transfer film has the following defects: the structural design of the support layer, air vent, and hot melt adhesive layer is unreasonable, the positioning between the three is difficult, it is only suitable for small-scale integrated molding production, it has strict requirements for molds and processing equipment, it is not suitable for automatic film bonding production between the various layers, and the production efficiency is low; in addition, although the support layer forms multiple air channels, the overall support effect of the transfer film is not good, and folding is easy to occur. Moreover, the support edge of the support layer is easy to cause wear to the transfer film, resulting in a short product life. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a film-forming mechanism in conjunction with a wiring mechanism to achieve automated continuous production. This seamlessly connects multiple processes such as film forming, wiring, and perforation, enabling automated production and significantly improving production efficiency and product consistency. Through precise timing control and spatial alignment, positioning is simple, ensuring the regularity of the grid structure on the breathable layer and the accuracy of the air vent positions. The grid structure avoids folding and guarantees the breathability of the air vents. The rational structure reduces wear and extends service life. This solves the problems of existing transfer films, such as unreasonable structure, easy folding, short lifespan, difficult positioning during production, difficulty in automation, and low production efficiency.

[0006] To address the above technical problems, the following technical solution is adopted: A composite transfer film forming system, comprising: A film-forming mechanism and a wiring mechanism disposed behind the film-forming mechanism along the film-forming direction, wherein the wiring mechanism includes a plurality of conveyor rollers spaced apart behind the film-forming mechanism, a transverse wiring assembly and a longitudinal wiring assembly disposed sequentially behind the film-forming mechanism and respectively corresponding to the conveyor rollers. The composite transfer film includes a breathable layer composed of multiple layers of film structure, multiple transverse reinforcing lines and longitudinal reinforcing lines that are equally spaced on one side of the breathable layer and form multiple grid structures with each other, and multiple breathable holes that penetrate the breathable layer and are located in the middle of each grid structure. When the conveying roller conveys the composite transfer film, the film bonding mechanism applies adhesive to multiple film structures to bond the breathable layer, and after the transverse wiring assembly and the longitudinal wiring assembly position and attach the transverse reinforcing line and the longitudinal reinforcing line on one side of the breathable layer, the film bonding mechanism positions and punches breathable holes on the breathable layer in the middle of the grid structure.

[0007] Preferably, the transverse wiring assembly includes a wiring roller rotatably disposed on the outside of the corresponding conveying roller, a plurality of wiring grooves equally spaced on the outer wall of the wiring roller, a plurality of negative pressure ports disposed in the wiring grooves, and a wire laying machine disposed on the outside of the wiring roller. The wiring roller rotates and, through the negative pressure port, attracts the transverse reinforcing wires in the wire laying machine into each of the wiring slots, thereby laying multiple transverse reinforcing wires at equal intervals onto the breathable layer.

[0008] Preferably, the longitudinal wiring assembly includes a pressure roller rotatably disposed on the outside of the corresponding conveying roller and rotating synchronously with the wiring roller, a plurality of equally spaced dividing grooves and pressure grooves formed on the outer wall of the pressure roller, and a wiring machine disposed on the outside of the pressure roller. The wiring machine, in conjunction with multiple branching grooves, lays multiple longitudinal reinforcing lines at equal intervals onto the breathable layer. At the same time, the pressure roller, in conjunction with the pressure grooves, presses the longitudinal reinforcing lines to adhere to the outside of the transverse reinforcing lines.

[0009] Preferably, the film-forming mechanism includes a coating machine, a grooving assembly, a film-forming roller, and a punching machine, which are sequentially arranged behind the coating machine and respectively corresponding to the conveying roller, and the grooving assembly and the transverse wiring assembly rotate synchronously. The composite transfer film also includes a plurality of clearance ring grooves formed on the side of the breathable layer away from the transverse reinforcing line and located on the outside of each of the breathable holes. The coating machine supports multiple membrane structures to apply adhesive, and in conjunction with the grooving assembly, after cutting the relief ring groove in one of the membrane structures, the film-forming roller combines the multiple membrane structures into the breathable layer with the relief ring groove, and then the punching machine positions and punches the breathable holes in the breathable layer.

[0010] Preferably, the grooving assembly includes a grooving roller rotatably disposed on the outside of the corresponding conveying roller and rotating synchronously with the transverse wiring assembly, a plurality of grooving blades spaced apart on the outer surface of the grooving roller, and a scraper movably disposed on the outside of the grooving roller and abutting against the corresponding conveying roller. After the grooving roller and the grooving knife are positioned on the membrane structure to cut the clearance groove, the cut waste material is attached to the conveying roller by the adhesive until it is scraped off by the scraper.

[0011] This application also provides a method for forming a transfer film, based on the above-mentioned composite transfer film forming system, including the following steps: Step 1: Wiring process. When the film-forming mechanism supports multiple film structures to apply adhesive and cooperates with the conveyor roller to form the breathable layer, the wiring mechanism positions and pastes the transverse reinforcing line and the longitudinal reinforcing line on one side of the breathable layer, forming the grid structure on one side of the breathable layer. Step 2: Drilling process. The film-forming mechanism positions and cuts one of the film structures away from the transverse reinforcing line, and then positions and forms a relief ring groove on the other side of the breathable layer of the film-forming mechanism. The film-forming mechanism then positions and drills the breathable hole on the breathable layer by positioning the mesh structure and / or the relief ring groove.

[0012] Preferably, a transfer film forming method further includes the following steps: Step 3: Glue application process. After the glue application mechanism forms a hot melt adhesive layer with multiple notches, the glue application mechanism, in conjunction with the conveying roller, positions and applies the hot melt adhesive layer onto the breathable layer, so that the notches are positioned on the outside of the corresponding clearance ring groove. Step 4: Forming process. The forming mechanism applies the film coating layer to both sides of the composite transfer film and forms an air guiding channel between the film coating layer and the longitudinal reinforcing line and the transverse reinforcing line. Then, the forming mechanism, together with the conveying roller, forms an easy-tear line on the composite transfer film at the location corresponding to the longitudinal reinforcing line.

[0013] Preferably, the glue application mechanism includes a forming roller that is rotatably disposed above the corresponding conveying roller and rotates synchronously with the transverse wiring assembly, a plurality of forming grooves that are spaced apart on the forming roller and interconnected with each other, a glue delivery assembly disposed above the forming roller, and a cooling assembly disposed outside the hot melt adhesive layer. The cooling component cools the forming roller, causing the liquid hot melt adhesive delivered by the adhesive conveying component to the forming tank to initially take shape. After the hot melt adhesive is adhered to the breathable layer by the forming roller, the cooling component further cools the hot melt adhesive to form the hot melt adhesive layer with the notch.

[0014] Preferably, the cooling assembly includes a baffle disposed on the glue supply assembly, a circulation channel formed in the forming roller, and a cooling chamber disposed on the outside of the breathable layer; The baffle prevents the hot melt adhesive from detaching from the molding tank until the circulating channel cools the hot melt adhesive and initially sets it. Then, the hot melt adhesive is adhered to the breathable layer and enters the cooling chamber for complete cooling.

[0015] Preferably, the forming mechanism includes a laminating machine arranged sequentially behind the coating mechanism, a cutting roller rotatably arranged behind the laminating machine and located outside the corresponding conveying roller, and cutting blades spaced apart on the cutting roller at the corresponding longitudinal reinforcing lines. After the laminating machine laminates the film, it uses the cutting blade and the cutting roller to position and cut out the easy-tear line.

[0016] The beneficial effects of this invention are: (1) In this invention, automatic continuous production is achieved by setting up a film bonding mechanism in conjunction with a wiring mechanism, seamlessly connecting multiple processes such as film bonding, wiring and perforation, realizing automated production, and simultaneously completing composite, reinforcement and functional processing in an integrated process, greatly improving production efficiency and product consistency. Through precise timing control and spatial alignment, positioning during production is simple, ensuring the regularity of the grid structure formed between the transverse reinforcement lines and the longitudinal reinforcement lines, while improving the accuracy of the vent hole position, thereby giving the composite transfer film excellent mechanical strength, dimensional stability and controllable breathability. (2) In this invention, by setting the synchronous rotation design of the grooving component and the transverse wiring component, a relief ring groove is pre-formed on a membrane structure before the film is closed, which facilitates the production and molding. After the film is closed, the formed relief ring groove is precisely positioned between the transverse reinforcing line and the longitudinal reinforcing line. At the same time, the perforation machine is used to drill holes in coordination, so that the ventilation hole can be accurately positioned in the center area of ​​the relief ring groove, ensuring the relief uniformity of the relief ring groove, improving the interlayer bonding quality and the rationality of the product structure, and finally realizing the integrated high-quality manufacturing of breathability, relief uniformity and consistent appearance. (3) In this invention, by setting the synchronous rotation of the forming roller and the transverse wiring assembly, the connected forming groove design on the forming roller, combined with the two-stage temperature control of the cooling assembly, allows the liquid hot melt adhesive to be initially shaped in the groove and pre-formed with a notch, thus realizing the precise pre-forming of the hot melt adhesive. This allows the hot melt adhesive to be accurately transferred and pasted onto the surface of the composite breathable layer, and then timely final curing to form a hot melt adhesive layer with a regular structure and strong adhesion, ensuring the consistency of the structure. In summary, this system offers advantages such as simple positioning during production, automated production, high production efficiency, and a reasonable structure in the produced transfer film, making it less prone to folding and with a long lifespan. It is particularly suitable for the field of transfer film production. Attached Figure Description

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1 like Figures 1-3 as well as Figures 6-7 As shown, a composite transfer film forming system includes: The film-forming mechanism 2 and the wiring mechanism 3 arranged behind the film-forming mechanism 2 along the film-forming direction, wherein the wiring mechanism 3 includes a plurality of conveying rollers 33 spaced apart behind the film-forming mechanism 2, a transverse wiring assembly 31 and a longitudinal wiring assembly 32 arranged sequentially behind the film-forming mechanism 2 and corresponding to the conveying rollers 33 respectively. When the conveyor roller 33 conveys the composite transfer film, the film bonding mechanism 2 applies adhesive to multiple film structures 111 to bond the film into a breathable layer 11. After the transverse wiring assembly 31 and the longitudinal wiring assembly 32 position and attach the transverse reinforcing line 121 and the longitudinal reinforcing line 122 on one side of the breathable layer 11, the film bonding mechanism 2 positions and punches a breathable hole 112 on the breathable layer 11 in the middle of the grid structure 12.

[0037] In this embodiment, by setting up a film bonding mechanism 2 in conjunction with a wiring mechanism 3, automated continuous production is achieved. Multiple processes, including bonding multiple film structures 111 into a breathable layer 11, wiring the transverse reinforcing lines 121 and longitudinal reinforcing lines 122, and punching the breathable holes 112, are seamlessly connected. Composite, reinforcement, and functional processing are completed simultaneously in an integrated process, which greatly improves production efficiency and product consistency. Through precise timing control and spatial alignment, the regularity of the grid structure 12 formed between the transverse reinforcing lines 121 and longitudinal reinforcing lines 122 is ensured, while improving the accuracy of the breathable hole 112 position. This gives the composite transfer film excellent mechanical strength, dimensional stability, and controllable breathability.

[0038] It should be noted that the transverse reinforcing line 121 and the longitudinal reinforcing line 122 are preferably elongated strip structures, which increases the connection area between the two and the breathable layer 11, improves the connection stability, and increases the area of ​​the support point 123 formed at the connection between the two, thereby improving the support effect.

[0039] Furthermore, such as Figures 7-8 As shown, the transverse wiring assembly 31 includes a wiring roller 311 rotatably disposed outside the corresponding conveying roller 33, a plurality of wiring grooves 312 equally spaced on the outer wall of the wiring roller 311, a plurality of negative pressure ports 313 disposed in the wiring grooves 312, and a filament laying machine disposed outside the wiring roller 311. The wiring roller 311 rotates and draws the transverse reinforcing wires 121 in the filament laying machine into each wiring groove 312 through the negative pressure port 313, thereby laying multiple transverse reinforcing wires 121 at equal intervals onto the breathable layer 11.

[0040] In this embodiment, the transverse reinforcing wires 121 from the filament layer are actively gripped and fixed in the filament tray 312 by the wiring roller 311 with negative pressure port 313. This ensures that multiple transverse reinforcing wires 121 maintain a preset equal spacing and stable tension during the conveying process, thereby forming a uniform, flat and firmly adhered transverse reinforcing grid on the breathable layer 11. This design not only greatly improves the speed and consistency of wiring and increases production efficiency, but also lays a key foundation for the overall mechanical properties and product reliability of the composite transfer film.

[0041] It should be noted that the filament placement machine itself and its installation method are existing technologies and are not shown in the attached drawings, so they will not be described in detail here.

[0042] Furthermore, such as Figure 7 as well as Figure 9 As shown, the longitudinal wiring assembly 32 includes a pressure roller 321 that is rotatably disposed on the outside of the corresponding conveying roller 33 and rotates synchronously with the wiring roller 311, a plurality of equally spaced wire dividing grooves 322 and pressure grooves 323 formed on the outer wall of the pressure roller 321, and a wiring machine disposed on the outside of the pressure roller 321. The wiring machine, in conjunction with multiple branching grooves 322, lays multiple longitudinal reinforcing lines 122 at equal intervals onto the breathable layer 11. At the same time, the pressure roller 321, in conjunction with the pressure groove 323, squeezes the longitudinal reinforcing lines 122 to adhere to the outside of the transverse reinforcing lines 121.

[0043] In this embodiment, by setting the synchronous rotation design of the pressure roller 321 and the wiring roller 311, the precise spatial overlap of the transverse reinforcing line 121 and the longitudinal reinforcing line 122 is achieved. The dividing groove 322 on the pressure roller 321 is responsible for accurately guiding and arranging the longitudinal reinforcing line 122 at equal intervals, thereby forming a uniform, flat and firmly adhered longitudinal reinforcing grid on the breathable layer 11. During the rotation process, the pressure groove 323 on it actively presses the longitudinal reinforcing line 122 and adheres it to the laid transverse reinforcing line 121, forming a precise mechanical interlock between the two, improving the stability of the connection, and forming a stable and raised support point 123, ensuring the stable and firm physical combination of the grid structure 12 in the transverse and longitudinal directions, and enhancing the overall shear resistance and deformation resistance.

[0044] It should be noted that the wire pressing groove 323 includes a positioning section 324 for positioning and pressing the transverse reinforcing line 121 and a pressing section 325 for pressing the longitudinal reinforcing line 122 to fit against the outside of the transverse reinforcing line 121. The two work together to achieve the pressing effect in the positioning state, avoiding interference during the pressing process and preventing misalignment. In addition, the wiring machine itself and the installation method are existing technologies and are not shown in the attached drawings, so they will not be described in detail here.

[0045] Furthermore, such as Figure 10 As shown, the film-forming mechanism 2 includes a coating machine 21, a grooving assembly 22, a film-forming roller 23, and a punching machine, which are sequentially arranged behind the coating machine 21 and respectively corresponding to the conveyor roller 33. The grooving assembly 22 and the transverse wiring assembly 31 rotate synchronously. The coating machine 21 supports multiple membrane structures 111 to apply adhesive, and after the grooving assembly 22 cuts a relief ring groove 113 in one membrane structure 111, the film-forming roller 23 combines the multiple membrane structures 111 into a breathable layer 11 with a relief ring groove 113, and then the punching machine positions and punches breathable holes 112 on the breathable layer 11.

[0046] In this embodiment, by setting the synchronous rotation design of the grooving assembly 22 and the wiring roller 311, the formed relief groove 113 is precisely positioned with the transverse reinforcing line 121 and the longitudinal reinforcing line 122. Before film closure, the relief groove 113 is pre-formed on a film structure 111 to facilitate production. After film closure, the coating machine 21 works in conjunction with the film closing roller 23 to punch holes, so that the ventilation hole 112 can be accurately positioned in the center area of ​​the relief groove 113, ensuring the relief uniformity of the relief groove 113 and guaranteeing the air permeability. The whole process seamlessly connects multi-layer composite, structural reservation and functional processing, significantly improving the interlayer bonding quality and product structure rationality, and finally achieving integrated high-quality manufacturing with air permeability, uniform relief and consistent appearance.

[0047] It should be noted that the coating machine 21 and the drilling machine themselves and their installation methods are all existing technologies. The drilling machine is not shown in the attached drawing and uses laser drilling technology for drilling, which will not be described in detail here.

[0048] Furthermore, such as Figures 10-11 As shown, the grooving assembly 22 includes a grooving roller 221 that is rotatably disposed on the outside of the corresponding conveying roller 33 and rotates synchronously with the transverse wiring assembly 31, a plurality of grooving blades 222 that are spaced apart on the outer surface of the grooving roller 221, and a scraper 223 that is movably disposed on the outside of the grooving roller 221 and abuts against the corresponding conveying roller 33. After the grooving roller 221 and the grooving knife 222 are positioned on the membrane structure 111 to cut out the clearance ring groove 113, the cut waste material is attached to the conveying roller 33 by the adhesive until it is scraped off by the scraper 223.

[0049] In this embodiment, by setting the synchronous rotation design of the grooving roller 221 and the wiring roller 311 and cooperating with the grooving blade 222, the seamless coordination of the pre-processing of the clearance ring groove 113 and the installation of the functional components of the transverse reinforcing line 121 is achieved. Moreover, the waste generated after grooving can be temporarily fixed on the surface of the conveying roller 33 with the help of adhesive until it is collected and removed by the movable scraper 223. This design not only ensures the continuous and stable cutting process and avoids the waste from flying or sticking and affecting the film surface quality, but also significantly improves the cleanliness and efficiency of production through synchronous movement and instant cleaning mechanism, providing a precise and clean substrate surface for subsequent production.

[0050] It should be noted that an auxiliary blade 224 is also movably disposed on the outer side of the grooving roller 221, which abuts against one side of the scraper 223. The auxiliary blade 224 can scrape off the waste material on the scraper 223, making it easy to clean. At the same time, the two can be used alternately, making it easy to replace the blade and avoid downtime.

[0051] Furthermore, such as Figure 6 as well as Figures 12-14As shown, the composite transfer film forming system also includes an adhesive coating mechanism 4 located behind the wiring mechanism 3. The adhesive coating mechanism 4 includes a forming roller 41 that is rotatably positioned above the corresponding conveying roller 33 and rotates synchronously with the transverse wiring assembly 31, a plurality of forming grooves 42 that are spaced apart on the forming roller 41 and interconnected with each other, an adhesive conveying assembly 43 located above the forming roller 41, and a cooling assembly 44 located outside the hot melt adhesive layer 13. The cooling component 44 cools the forming roller 41, so that the liquid hot melt adhesive conveyed by the glue conveying component 43 to the forming tank 42 is initially shaped. After the hot melt adhesive is pasted onto the breathable layer 11 by the forming roller 41, the cooling component 44 further cools the hot melt adhesive to form a hot melt adhesive layer 13 with notches 131.

[0052] In this embodiment, by setting the synchronous rotation of the forming roller 41 and the transverse wiring assembly 31, and the design of the connected forming groove 42 on the forming roller 41 in conjunction with the two-stage temperature control of the cooling assembly 44, the liquid hot melt adhesive is first initially shaped in the groove and a notch 131 is pre-formed, thus realizing the precise pre-forming of the hot melt adhesive. This allows the hot melt adhesive to be accurately transferred and pasted onto the surface of the composite breathable layer 11, and then timely final curing is performed to form a hot melt adhesive layer 13 with a regular structure and strong adhesion, achieving efficient transfer and bonding, ensuring structural consistency, and guaranteeing the positioning between the pre-formed notch 131 and the clearance ring groove 113.

[0053] It should be noted that the glue conveying assembly 43 keeps the hot melt glue in a liquid state by heating it at high temperature, and facilitates its flow and delivery to the forming groove 42 of the forming roller 41 under the action of gravity. Both the assembly itself and the installation method are existing technologies and will not be described in detail here. The structure that enables the synchronous rotation of the wire winding roller 311, the wire pressing roller 321, the grooving roller 221 and the forming roller 41 is a chain drive or belt drive, etc. Both the assembly itself and the installation method are existing technologies and are not shown in the attached drawings, so they will not be described in detail here.

[0054] Furthermore, such as Figures 12-14 As shown, the cooling assembly 44 includes a baffle 441 disposed on the glue conveying assembly 43, a circulation channel 442 formed in the forming roller 41, and a cooling chamber 443 disposed on the outside of the breathable layer 11. The baffle 441 prevents the hot melt adhesive from leaving the molding tank 42. After the hot melt adhesive is initially cooled and shaped by the circulation channel 442, it can be adhered to the breathable layer 11 and enter the cooling chamber 443 for complete cooling.

[0055] In this embodiment, by setting baffle 441 to block the cooling of the circulation channel 442, the liquid hot melt adhesive is ensured to be fully constrained in the molding tank 42 and uniformly pre-cooled to achieve initial shaping, ensuring the shape accuracy and consistency of the hot melt adhesive layer 13, especially at the notch 131. Subsequently, the cooling chamber 443 provides an enhanced final cooling environment, which enables the hot melt adhesive layer 13 to be quickly cured and firmly bonded, improving production efficiency and composite reliability, and achieving high-quality functional adhesive coating.

[0056] In detail, during molding, the glue delivery assembly 43 injects liquid hot melt adhesive into the molding groove 42 above one side of the molding roller 41. At this time, the baffle 441 prevents the hot melt adhesive from overflowing, and the internal circulation channel 442 of the molding roller 41 performs preliminary cooling and shaping, so that a solidified shell is formed on the outside of the hot melt adhesive. Then, the pre-shaped hot melt adhesive with the notch 131 leaves the baffle 441 as the roller rotates. The outside of the hot melt adhesive flows outward under the action of gravity until the hot melt adhesive rotates to the bottom of the other side of the molding roller 41. The hot melt adhesive flows back under the action of gravity, ensuring the shape accuracy and consistency when the hot melt adhesive is pressed onto the surface of the breathable layer 11. Finally, the hot melt adhesive enters the external cooling chamber 443 along with the breathable layer 11, and completes the final curing in a controlled low temperature environment, thereby efficiently forming a regular and firmly bonded hot melt adhesive layer 13.

[0057] It should be noted that the circulation channel 442 has a spiral structure and there are multiple channels to improve the heat transfer effect. By introducing cooling air or liquid, the uniformity and stability of the cold cutting are improved. In addition, there are two cooling chambers 443, which are respectively set on the front and rear sides of the forming roller 41, so as to cool the adhesive and hot melt glue respectively, so as to cool and fix them in time, improve the stability of the structure, and avoid misalignment during subsequent production.

[0058] Furthermore, such as Figures 1-6 as well as Figures 15-16 As shown, the composite transfer film forming system also includes a forming mechanism 5 located behind the coating mechanism 4. The forming mechanism 5 includes a laminating machine 51 located behind the coating mechanism 4, a cutting roller 52 rotatably located behind the laminating machine 51 and outside the corresponding conveying roller 33, and a cutting blade 53 spaced at intervals on the cutting roller 52 at the corresponding longitudinal reinforcing line 122. After the laminating machine 51 laminates the film layer 14, it uses the cutting blade 53 and the cutting roller 52 to position and cut out the easy-tear line 15.

[0059] In this embodiment, by setting the cutting roller 52 and the cutting blade 53 in conjunction with the conveying roller 33, the composite transfer film formed by the film coating layer 14 of the laminating machine 51 can be cut precisely to form an easy-tear line 15 that is precisely positioned and runs through the longitudinal reinforcing line 122, thus ensuring the easy-tear function of the composite transfer film, facilitating the use of the product, and making the production of the easy-tear line 15 efficient and consistent.

[0060] It should be noted that the cutting blade 53 includes a cutting segment 531 corresponding to the longitudinal reinforcing line 122 and an extension segment 532 located at both ends of the cutting segment 531 and extending obliquely to both sides for cutting. When the cutting segment 531 just cuts the transverse reinforcing line 121, the extension segment 532 can completely cut the transverse reinforcing line 121. At the same time, the extension segment 532 causes the end of the easy-tear line 15 to extend obliquely outward to form two easy-tear points 151, which are convenient for tearing and use. The cutting roller 52 is provided with trimming blades 314 at both ends to trim the composite transfer film, ensuring the neatness of the edge, preventing the transverse reinforcing line 121 from protruding, and ensuring the complete coverage of the transverse reinforcing line 121. In addition, the laminating machine 51 itself and its installation method are existing technologies and will not be described in detail here.

[0061] Example 2 like Figures 1-5 As shown, a composite transfer film is produced by forming a composite transfer film forming system as described in Example 1, comprising: The breathable layer 11 is formed by laminating a multilayer membrane structure 111; a plurality of transverse reinforcing lines 121 and longitudinal reinforcing lines 122 are equally spaced on one side of the breathable layer 11 and form a plurality of grid structures 12 between each other; a plurality of breathable holes 112 are formed through the breathable layer 11 and located in the middle of each grid structure 12; a plurality of clearance annular grooves 113 are formed on the other side of the breathable layer 11 and are respectively located outside each breathable hole 112; a hot melt adhesive layer 13 is set on the side of the breathable layer 11 with clearance annular grooves 113 and has a notch 131 formed at the clearance annular grooves 113; two coating layers 14 are respectively set outside the longitudinal reinforcing lines 122 and the hot melt adhesive layer 13; an air guiding channel 141 is formed between the coating layer 14 and the longitudinal reinforcing lines 122 and the transverse reinforcing lines 121; and an easy-tear line 15 penetrates the coating layer 14, the longitudinal reinforcing lines 122 and the breathable layer 11.

[0062] In this embodiment, the grid structure 12 formed by the transverse reinforcing lines 121 and the longitudinal reinforcing lines 122 significantly improves the overall mechanical strength and dimensional stability. The clearance ring groove 113 and the hot melt adhesive layer 13 with notches 131 work together to improve the stability of the connection after the hot melt adhesive layer 13 is transferred, while avoiding clogging of the vent holes 112. In addition, the vent holes 112 and the air guide channels 141 located at the center of the grid structure 12 optimize the air circulation efficiency, ensuring efficient and uniform air permeability. The surface coating layer 14 provides protection and decoration, while the easy-tear line 15 that precisely runs through the longitudinal reinforcing lines 122 makes the product both convenient to use and reliable overall. Thus, this composite transfer film design has multiple advantages such as high strength, excellent air permeability, easy processing and peeling, and durability.

[0063] Example 3 like Figures 1-6 as well as Figures 17-18 As shown, a transfer film forming method, based on a composite transfer film forming system in Example 1, includes the following steps: Step 1: Wiring process. When the film-forming mechanism 2 supports multiple film structures 111, applies adhesive, and cooperates with the conveyor roller 33 to form the breathable layer 11, the wiring mechanism 3 positions and pastes the transverse reinforcing line 121 and the longitudinal reinforcing line 122 on one side of the breathable layer 11, forming a grid structure 12 on one side of the breathable layer 11. Step 2: Drilling process. The membrane assembly mechanism 2 positions and cuts a membrane structure 111 away from the transverse reinforcing line 121. Then, after positioning and forming a relief groove 113 on the other side of the breathable layer 11 of the membrane assembly, the membrane assembly mechanism 2 positions and drills a breathable hole 112 on the breathable layer 11 through the positioning grid structure 12 and / or relief groove 113. Step 3: Glue application process. After the hot melt adhesive layer 13 with multiple notches 131 is formed by the glue application mechanism 4, the glue application mechanism 4, together with the conveying roller 33, positions and applies the hot melt adhesive layer 13 onto the breathable layer 11, so that the notches 131 are positioned on the outside of the corresponding relief ring groove 113. Step 4: Forming process. The forming mechanism 5 applies the film coating layer 14 to both sides of the composite transfer film and forms an air guiding channel 141 between the film coating layer 14 and the longitudinal reinforcing line 122 and the transverse reinforcing line 121. Then, the forming mechanism 5, together with the conveying roller 33, forms an easy-tear line 15 through the longitudinal reinforcing line 122 on the composite transfer film.

[0064] In this embodiment, a mesh structure 12 is first constructed as a structural reference by setting up a wiring process. Then, the perforation process relies on the mesh structure 12 and the pre-cut clearance groove 113 to accurately position the ventilation holes 112, ensuring the alignment accuracy of function and structure. At the same time, the adhesive application process is used to fit the hot melt adhesive layer 13 with notches 131 into the clearance groove 113, achieving a firm bond while retaining the ventilation channel. Finally, the protective and usability functions are perfected by the forming of the film and the precise easy-tear line 15. This transfer film forming method realizes the efficient integrated production of composite transfer film through the precise timing arrangement of the process and the interlocking design of the structure. Moreover, the semi-finished structure output from each step provides a positioning reference or functional reservation for subsequent processes, thereby ensuring the mechanical strength, air permeability uniformity, adhesion reliability and ease of use of the product in continuous production.

[0065] It should be noted that the formed composite transfer film is wound onto the support roll 16 by a winding machine to form a transfer film roll, which is convenient for collection, storage and transportation. The winding machine itself and the installation method are existing technologies and are not shown in the attached drawings, so they will not be described in detail here.
