Description

Technical Field

[0001] This application relates to the technical field of conveyor line equipment, and more particularly to a touch film conveying device. Background Technology

[0002] In the production process of touch screen film, roller conveyor lines are commonly used to automate the flow of products between various processes. There is a fixed gap between the rollers in the conveyor line. When the touch screen film being conveyed has the characteristics of large size, large thickness, and heavy weight, as the film moves on the conveyor line, when its front edge is exactly aligned with the gap between the rollers, the front edge of the film will bend downward under its own weight because there is no roller support in the gap area. The continuous operation of the conveyor line will cause the bent edge to continue to move forward, and then make a hard impact with the normally rotating roller in front. This will eventually lead to problems such as creases, cracks, gaps, or damage to the surface functional layer of the film edge, resulting in defective products. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a touch film conveying device that can solve the problem that the touch film is prone to collision with the roller in front due to bending when conveying the touch film in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution: A touch film delivery device is provided, comprising: The conveyor roller array includes multiple rollers arranged parallel to each other along the conveying direction. The rotation of the rollers pushes the touch film on them to move along the conveying direction. A support belt is disposed on the conveying roller row along the conveying direction and covers multiple rollers. At least two support belts are spaced apart in a direction perpendicular to the conveying direction. The support belt supports a local area of ​​the touch film and prevents the edge of the touch film from bending and hitting the rollers.

[0005] In the touch film conveying equipment provided in this embodiment, the multi-point support of the support belt effectively avoids surface scratches, indentations, and internal structural damage caused by the downward bending of the touch film edge impacting the roller shaft. This significantly reduces the generation of defective products, improves the overall product quality, and reduces production cost waste caused by product defects. The slender strip or filament structure of the support belt and the reasonable multi-point support setting provide stable support while generating almost no additional resistance to the movement of the touch film. The conveying roller shaft row can smoothly push the touch film to move, ensuring the smoothness and efficiency of the conveying process, and the production rhythm will not be affected by the setting of the support device. In addition, compared with some solutions that solve the problem of downward bending of the touch film edge by adding complex auxiliary support structures, the conveying equipment structure of this application is more streamlined, achieving this only by adding a support belt, reducing unnecessary parts, reducing the manufacturing difficulty and cost of the equipment, and also making the equipment more compact and saving production space.

[0006] In one embodiment, the system further includes a fixing frame located below the conveyor roller shaft row, and the support belt includes a first support belt, the main body of which is laid on the upper surface of the conveyor roller shaft row, and both ends extending downward from the gap of the conveyor roller shaft row and fixed to the fixing frame.

[0007] In this embodiment, the first support belt is fixed at both ends to a mounting bracket below the conveyor roller shaft row. This fixing method greatly enhances the stability of the support belt. During the touch film conveying process, even under the influence of factors such as the friction of the touch film, its own weight, and equipment vibration, the support belt will not easily shift or loosen, and can always maintain the correct position to provide stable support for the touch film, ensuring the reliability of the support effect. Furthermore, the design of the mounting bracket makes the installation of the first support belt relatively simple. During equipment assembly, it is only necessary to accurately fix both ends of the first support belt in the corresponding positions on the mounting bracket, without the need for complex adjustments and calibrations, thus improving the installation efficiency of the equipment. When maintenance or replacement of the first support belt is required, since its two ends are fixed to the mounting bracket, operators can easily disassemble and install it. Large-scale disassembly of the entire conveyor roller shaft row is not required, reducing maintenance time and difficulty, and lowering maintenance costs.

[0008] In one embodiment, one or more sets of the first support belts are arranged in a direction parallel to the conveying direction, and the main body of the first support belts covers all the rollers.

[0009] In this embodiment, one or more sets of first support belts fully cover the upper surface of all rollers. This means that the touch film can be directly supported by the first support belts throughout the entire conveying path. No matter where the touch film is located, the first support belts below it provide stable support, effectively preventing the touch film from being deformed due to its own weight or external factors.

[0010] In one embodiment, the fixing frame includes a fixing beam and fasteners mounted on the fixing beam. The fixing beam extends in a direction parallel to the roller shaft. The mounting position of the fasteners on the fixing beam is adjustable along the extension direction of the fixing beam. The end of the first support belt is fixed to the fasteners.

[0011] In this embodiment, the first support belt can be positioned appropriately by simply adjusting the fasteners, without requiring large-scale modifications or component replacements, thus greatly improving the equipment's versatility and adaptability. Furthermore, adjusting the fasteners to position the first support belt ensures precise support of the touch film, guaranteeing that it covers the critical stress areas of the touch film and provides uniform and stable support. This effectively avoids issues of excessive or insufficient localized stress on the touch film caused by improper support positioning, reducing deformation and damage during transport and improving product quality stability.

[0012] In one embodiment, the fixed beam is provided with a mounting groove extending along its own length, and the fastener adjusts its installation position by sliding along the mounting groove.

[0013] The mounting groove allows for continuous sliding of the fasteners, enabling operators to more precisely adjust the first support strip to the desired position. This allows for more detailed matching of touch screen membranes of different widths, making it particularly suitable for production scenarios with high requirements for support position accuracy. It effectively reduces touch screen membrane deformation caused by support position deviations. During production, if frequent changes to touch screen membranes of different widths are required, operators can quickly push the fasteners along the groove to rapidly adjust the position of the first support strip, significantly reducing equipment adjustment time and improving production efficiency.

[0014] In one embodiment, a plurality of mounting holes are provided at intervals along the length of the fixed beam, and the fastener is adjusted in position by cooperating with different mounting holes.

[0015] The structure with mounting holes on the fixed beam is relatively simple, eliminating the need for complex grooving processes, thus reducing the manufacturing difficulty and cost of the fixed beam. Each mounting hole corresponds to a specific position, allowing operators to more accurately position the first support band to the required location when installing fasteners. For production scenarios where the accuracy of support position is not particularly high but stable support is required, the mounting hole solution can provide reliable positioning results.

[0016] In one embodiment, the fastener includes a bolt and a nut, and the end of the first support band is fixed to the bolt; the bolt includes a rod and a nut connected to one end of the rod, and the nut is threadedly connected to the rod, so that the nut and the nut cooperate to clamp onto the fixed beam by tightening the nut.

[0017] In this embodiment, the design of using a nut and bolt to clamp the fixed beam generates a strong and stable clamping force. During equipment operation, even under external forces such as tension during touch film transport and equipment vibration, the bolts remain firmly fixed to the fixed beam, preventing displacement of the first support belt. This provides continuous and stable support for the touch film, effectively avoiding problems such as touch film deformation and unstable transport caused by loose support belts. Loosening and tightening the nuts is relatively simple, requiring no complex tools or professional skills. Operators can quickly and easily adjust the position of the first support belt, significantly shortening equipment adjustment time and improving production efficiency. Especially in production scenarios requiring frequent changes to touch films of different widths, this convenient adjustment method significantly enhances production flexibility and response speed.

[0018] In one embodiment, the first support strip is a cylindrical wire with a diameter of no more than 2 mm.

[0019] In this embodiment, a first support belt made of fine filaments is used. This line-contact support significantly reduces the contact area between the first support belt and the touch film surface, thus lowering the friction between them. The lower resistance and better support stability allow the equipment to transport the touch film at a higher speed, improving production efficiency while ensuring the quality of the touch film and meeting the needs of large-scale production. Because the cylindrical filaments offer little resistance to the roller movement, the equipment does not require excessive energy to overcome the friction between the support components and the roller during operation. This not only reduces energy consumption and operating costs but also aligns with the current trend of energy conservation and environmental protection.

[0020] In one embodiment, the conveying roller array includes an outer frame in which the rollers are mounted; the outer frame includes a horizontal frame parallel to the rollers; the support belt includes a second support belt, one end of which is fixed to the horizontal frame and the other end of which extends toward the rollers, such that the main body of the second support belt can rest on the rollers.

[0021] In this embodiment, one end of the second support belt is fixed to the horizontal frame to ensure that it covers the gap between the horizontal frame and the edge rollers, guaranteeing a smooth transition of the touch film between the rollers and the horizontal frame. When the touch film moves from the roller area to near the horizontal frame, the second support belt provides additional support to prevent the touch film from lifting or wrinkling at the edges due to loss of support, ensuring that the touch film can pass smoothly through the entire conveying area.

[0022] In one embodiment, the second support strip is a flat strip with a width of no more than 5 cm and a thickness of no more than 2 mm.

[0023] In this embodiment, since the second support belt is fixed to the horizontal frame at only one end and not at the other, the use of a flat belt provides good stability and ensures stable support. The second support belt rests on the roller, and its flat shape and flexibility allow it to adapt to the roller's rotational movement. When the roller rotates, relative sliding occurs between the second support belt and the roller surface, but due to its flat and thin structure, this sliding friction is small and does not significantly hinder the roller's rotation. Simultaneously, the free end of the second support belt can adaptively adjust according to the rotation of the roller and the movement of the touch film, ensuring a consistently stable transition support for the touch film.

[0024] In one embodiment, the support strip is made of polycarbonate, polymethyl methacrylate, or polytetrafluoroethylene.

[0025] All of the above materials have the advantages of smooth surface, low coefficient of friction, and good wear resistance. When the touch film slides on these surfaces, the resistance is small, which is conducive to the smooth transport of the touch film and reduces static electricity and wear caused by friction. At the same time, the above materials have sufficient strength and rigidity to provide stable and reliable support, ensuring that the touch film will not sag or deform due to insufficient support during transport.

[0029] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] Currently, touch technology has formed three main technical routes: metal mesh, nano-silver, and ITO. Among them, ITO (indium tin oxide) is an N-type oxide semiconductor, with its main performance indicators being resistivity and light transmittance. ITO thin films, or indium tin oxide semiconductor transparent conductive films, are mainly used as transparent electrodes in display devices such as LCDs and OLEDs, ensuring that the device can both transmit light to display images and conduct electrical signals. Furthermore, capacitive and resistive touchscreens use ITO as an electrode material; its transparency and conductivity determine the sensitivity and visual effect of the touch device.

[0033] In the ultra-large size field, the full-lamination solution mainly involves bonding the touch panel (TP) and octane sensor (OC) together using OCR adhesive. This process is lengthy and complex, resulting in higher costs. The zero-lamination solution, on the other hand, directly bonds the TP and OC together using foam adhesive around the edges. This process is simpler, shorter, and less expensive. However, the zero-lamination solution requires a thicker substrate, making the touch film heavier.

[0034] In the production process of touch screen film, roller conveyor lines are commonly used to automate the flow of products between various processes. There is a fixed gap between the rollers in the conveyor line. When the touch screen film being conveyed has the characteristics of large size, large thickness, and heavy weight, as the film moves on the conveyor line, when its front edge is exactly aligned with the gap between the rollers, the front edge of the film will bend downward under its own weight because there is no roller support in the gap area. The continuous operation of the conveyor line will cause the bent edge to continue to move forward, and then make a hard impact with the normally rotating roller in front. This will eventually lead to problems such as creases, cracks, gaps, or damage to the surface functional layer of the film edge, resulting in defective products.

[0035] Currently, the industry has attempted some improvements to address this issue, but all have certain limitations. For example, some companies reduce the gap between rollers to decrease the likelihood of the film edge bending downwards; however, this increases the manufacturing difficulty and cost of the rollers, while also reducing the flexibility of the conveyor line and its adaptability to products of different sizes. Other companies use auxiliary support devices at the roller gaps, but these devices are often complex in structure, inconvenient to install and maintain, and may cause secondary damage to the surface of the touch film.

[0036] To overcome the above technical problems, refer to Figures 1-2 This application provides a touch film conveying device, comprising: The conveyor roller row 1 includes multiple rollers 11 arranged parallel to each other along the conveying direction. The rotation of the rollers 11 pushes the touch film on them to move along the conveying direction. A support belt is disposed on the conveying roller row 1 along the conveying direction and covers multiple rollers 11. At least two support belts are spaced apart in a direction perpendicular to the conveying direction. The support belts support a local area of ​​the touch film and prevent the edge of the touch film from bending and hitting the rollers 11.

[0037] The conveyor roller row 1 comprises multiple rollers 11, all arranged parallel to each other along the conveying direction of the touch film. The rollers 11 are typically linked by a transmission mechanism (such as a chain or gear) to ensure synchronous rotation. The rollers 11 provide the core power for the movement of the touch film through their own rotation, and simultaneously, due to their large contact area with the film, they undertake the main support task, ensuring conveying stability. During conveying, the contact area between the rollers 11 and the touch film is sufficiently large to effectively transmit rotational thrust and provide reliable support for the film in the main conveying area.

[0038] The touch film conveying equipment of this embodiment typically also includes a frame (not shown), and the conveying roller shaft row 1 is mounted on the frame so that it can be maintained at a sufficient height to connect the front and rear work positions.

[0039] The support strips typically employ a thin, elongated strip or filament structure. Their contact area with the touch film is much smaller than that of the roller 11, serving only as a line-contact auxiliary support and not affecting the power transmission of the roller 11. Two or more support strips are spaced laterally to ensure coverage of critical areas where the touch film is prone to bending (such as the two edges in the width direction). This ensures that the film can cover the gaps in the roller 11 through multi-point support whenever it moves in any position, preventing localized suspension.

[0040] In terms of specific layout, an appropriate number of support strips can be set according to the width of the touch film. Generally speaking, the larger the width of the touch film, the more support strips can be added to increase the number of line supports and prevent the touch film from bending too much locally due to gravity.

[0041] In this embodiment, during operation of the touch film conveying device, the frictional force generated by the rotation of the roller 11 acts on the bottom surface of the touch film, driving the film to move forward along the conveying direction, and relative sliding occurs between the film and the fixed support belt. When the leading edge of the film moves into the gap of the roller 11, the fixed support belt precisely supports the edge of the film from below, forming an upward supporting force that counteracts the downward bending moment generated by the weight of the film itself, preventing the edge from being suspended in the air. Because the support belt is fixed and has a small contact area, when the film slides on its surface, it will not hinder the conveying due to excessive friction, nor will it cause scratches on the surface of the film due to sliding.

[0042] In summary, the touch film conveying equipment provided in this embodiment effectively avoids surface scratches, indentations, and internal structural damage caused by the downward bending of the touch film edge against the roller shaft 11 through multi-point support of the support belt. This significantly reduces the generation of defective products, improves the overall product quality, and reduces production cost waste caused by product defects. The slender strip or filament structure of the support belt and the reasonable multi-point support setting provide stable support while generating almost no additional resistance to the movement of the touch film. The conveying roller shaft row 1 can smoothly push the touch film to move, ensuring the smoothness and efficiency of the conveying process, and the production rhythm will not be affected by the setting of the support device. In addition, compared with some solutions that solve the problem of downward bending of the touch film edge by adding complex auxiliary support structures, the conveying equipment structure of this application is more streamlined, achieving this only by adding a support belt, reducing unnecessary parts, reducing the manufacturing difficulty and cost of the equipment, and making the equipment more compact, saving production space.

[0043] In one embodiment, a fixing frame 4 is also included below the conveyor roller shaft row 1. The support belt includes a first support belt 31. The main body of the first support belt 31 is laid on the upper surface of the conveyor roller shaft row 1, and both ends extend downward from the gap of the conveyor roller shaft row 1 and are fixed to the fixing frame 4.

[0044] The fixing frame 4 is located directly below the conveyor roller shaft row 1, which plays the role of stabilizing the first support belt 31. The main body of the first support belt 31 is laid on the upper surface of the conveyor roller shaft row 1, and directly contacts the touch film to provide support. Its two ends extend downward from the gap between adjacent roller shafts 11 in the conveyor roller shaft row 1, and are finally fixed on the fixing frame 4, forming a stable support structure system.

[0045] Since the first support belt 31 is fixed at both ends to the fixed frame 4 below the conveyor roller shaft row 1, during the movement of the touch film, especially when the front edge of the touch film is in the gap area of ​​the roller shaft 11, the first support belt 31 can provide an upward support force to the edge of the touch film through its tension and fixed structure, preventing the edge of the touch film from bending downward due to its own weight. This combination of upper main body support and lower fixed tension forms a stable support force field, effectively preventing the edge of the touch film from hitting the front roller shaft 11.

[0046] In this embodiment, the first support belt 31 is fixed at both ends to the fixing frame 4 below the conveyor roller shaft row 1. This fixing method greatly enhances the stability of the support belt. During the touch film conveying process, even under the influence of factors such as the friction of the touch film, its own weight, and equipment vibration, the support belt will not easily shift or loosen, and can always maintain the correct position to provide stable support for the touch film, ensuring the reliability of the support effect. Furthermore, the design of the fixing frame 4 makes the installation of the first support belt 31 relatively simple. During equipment assembly, it is only necessary to accurately fix both ends of the first support belt 31 to the corresponding positions on the fixing frame 4, without the need for complex adjustment and calibration processes, thus improving the installation efficiency of the equipment. When maintenance or replacement of the first support belt 31 is required, since its two ends are fixed to the fixing frame 4, operators can easily disassemble and install it. Large-scale disassembly of the entire conveyor roller shaft row 1 is not required, reducing the time and difficulty of maintenance work and lowering maintenance costs.

[0047] Among them, the fixing frame 4 can be the frame of the touch film conveying equipment, that is, no additional components are needed; or it can be an additional structural component to meet more functional requirements.

[0048] In one embodiment, one or more sets of the first support belts 31 are arranged in a direction parallel to the conveying direction, and the main body of the first support belts 31 covers all the rollers 11.

[0049] Specifically, when one set of first support belts 31 is provided along the conveying direction, the first support belts 31 need to cover all rollers 11; when multiple sets of first support belts 31 are provided along the conveying direction, each first support belt 31 can cover a portion of the rollers 11, as long as all the first support belts 31 can eventually cover all the rollers 11. In this embodiment, one or more sets of first support belts 31 fully cover the upper surface of all rollers 11. This means that the first support belts 31 can provide direct support throughout the entire conveying path of the touch film. No matter where the touch film is located, the first support belts 31 below it provide stable support, effectively preventing the touch film from being deformed due to its own weight or external factors.

[0050] In one embodiment, the fixing frame 4 includes a fixing beam 41 and a fastener 42 mounted on the fixing beam 41. The fixing beam 41 extends in a direction parallel to the roller shaft 11. The mounting position of the fastener 42 on the fixing beam 41 can be adjusted along the extension direction of the fixing beam 41. The end of the first support belt 31 is fixed to the fastener 42.

[0051] When conveying touch films of different widths, the operator can adjust the mounting position of the fastener 42 on the fixed beam 41 according to the actual width of the touch film. Since the end of the first support belt 31 is fixed to the fastener 42, changing the position of the fastener 42 will cause a corresponding adjustment in the position of the first support belt 31. In this way, the first support belt 31 can accurately cover the effective support area of ​​the touch film, providing appropriate and effective support for touch films of different widths, and preventing the touch film from deforming or bending at the edges due to insufficient support during conveying.

[0052] In this embodiment, the first support belt 31 can be positioned appropriately by simply adjusting the position of the fastener 42, without requiring large-scale modifications or component replacements, thus greatly improving the equipment's versatility and adaptability. Furthermore, adjusting the position of the first support belt 31 by adjusting the fastener 42 ensures precise support of the touch film, guaranteeing that the first support belt 31 covers the critical stress areas of the touch film, providing uniform and stable support. This effectively avoids problems of excessive or insufficient localized stress on the touch film due to improper support positioning, reducing deformation and damage to the touch film during transport, and improving product quality stability.

[0053] In one embodiment, reference is made to Figure 3 The fixed beam 41 is provided with an installation groove 411 extending along its own length direction, and the fastener 42 adjusts its installation position by sliding along the installation groove 411.

[0054] When it is necessary to accommodate touch films of different widths, the operator loosens the fastener 42 and pushes it to slide within the mounting groove 411. Since the end of the first support band 31 is fixed to the fastener 42, the change in the position of the fastener 42 will cause the position of the first support band 31 to change accordingly. In this way, the first support band 31 can accurately cover the effective support area of ​​the touch film, providing appropriate support for touch films of different widths and preventing problems such as deformation and edge bending of the touch film due to insufficient support during transportation.

[0055] The mounting groove 411 allows the fastener 42 to slide continuously, enabling operators to more precisely adjust the first support strip 31 to the required position. This allows for more detailed matching of touch films of different widths, making it particularly suitable for production scenarios with high requirements for support position accuracy. It effectively reduces touch film deformation caused by support position deviations. During production, if frequent changes to touch films of different widths are required, operators can quickly push the fastener 42 to slide within the groove, rapidly adjusting the position of the first support strip 31, significantly shortening equipment adjustment time and improving production efficiency.

[0056] In another embodiment, the fixed beam 41 is provided with a plurality of mounting holes spaced apart along its own length direction, and the fastener 42 adjusts the installation position by cooperating with different mounting holes.

[0057] When faced with touch screen films of different widths, the operator selects the appropriate mounting hole on the fixing beam 41 according to the size of the touch screen film and installs the fastener 42 in the hole. Because the end of the first support band 31 is fixed to the fastener 42, changing the installation position of the fastener 42 will adjust the position of the first support band 31 accordingly, so that the first support band 31 can accurately cover the required support area of ​​the touch screen film, achieving effective support for touch screen films of different widths.

[0058] The structure with mounting holes on the fixed beam 41 is relatively simple, eliminating the need for complex grooving processes, thus reducing the manufacturing difficulty and cost of the fixed beam 41. Each mounting hole corresponds to a specific position, allowing operators to more accurately position the first support band 31 to the required location when installing the fastener 42. For some production scenarios where the accuracy of the support position is not particularly high but stable support is required, the mounting hole solution can provide a reliable positioning effect.

[0059] In one embodiment, reference is made to Figure 4 The fastener 42 includes a bolt 421 and a nut 422. The end of the first support band 31 is fixed to the bolt 421. The bolt 421 includes a rod 4211 and a nut 4212 connected to one end of the rod 4211. The nut 422 is threaded to the rod 4211. By tightening the nut 422, the nut 422 and the nut 4212 are clamped onto the fixed beam 41.

[0060] When the position of the first support band 31 needs to be adjusted to accommodate touch films of different widths, the operator first loosens the nut 422 to release the clamping force between the nut 422 and the screw 4212 on the fixed beam 41, allowing the bolt 421 (along with the end of the first support band 31 fixed thereto) to move on the fixed beam 41 (if the fixed beam 41 has a mounting groove 411, it slides along the groove; if it has a mounting hole, it moves to the appropriate mounting hole position). After the first support band 31 is adjusted to the appropriate position, the nut 422 is tightened. As the nut 422 screws into the bolt 421, the distance between the nut 422 and the screw 4212 gradually decreases, generating a clamping force on the fixed beam 41, firmly fixing the bolt 421 to the fixed beam 41, thereby determining the position of the first support band 31 and providing effective support for the touch film.

[0061] In this embodiment, the design of using nut 422 and bolt 4212 to clamp the fixing beam 41 generates a strong and stable clamping force. During equipment operation, even under external forces such as tension during touch film conveying and equipment vibration, the bolt 421 remains firmly fixed to the fixing beam 41, preventing the first support belt 31 from shifting position. This provides continuous and stable support for the touch film, effectively avoiding problems such as touch film deformation and unstable conveying caused by loose support belts. Loosening and tightening the nut 422 is relatively simple, requiring no complex tools or professional skills. Operators can quickly and easily adjust the position of the first support belt 31, greatly shortening equipment adjustment time and improving production efficiency. Especially in production scenarios where different width touch films need to be frequently changed, this convenient adjustment method can significantly improve production flexibility and response speed.

[0062] In one embodiment, reference is made to Figure 3 The fixed beam 41 is provided with an upward-opening mounting groove 411 extending along its own length. The two side walls of the mounting groove 411 are provided with opposing and pre-dated retaining edges 412. The nut 4212 of the fastener 42 is located in the mounting groove 411 and is restricted below the retaining edge 412. The rod 4211 extends upward and is connected to the nut 422. When the nut 422 is loosened, the fastener 42 can slide along the mounting groove 411. When the nut 422 is tightened, the nut 422 and the nut 4212 clamp the retaining edge 412 to fix the fastener 42.

[0063] The design of the nut 422 and the screw cap 4212 clamping the retaining edge 412 generates a strong and stable clamping force. During equipment operation, even under external forces such as tension during touch film conveying and equipment vibration, the fastener 42 remains firmly fixed within the mounting groove 411, preventing displacement of the first support belt 31. This provides continuous and stable support for the touch film, effectively avoiding problems such as touch film deformation and unstable conveying caused by loose support belts, thus ensuring product quality.

[0064] In one embodiment, the first support band 31 is a cylindrical wire with a diameter of no more than 2 mm.

[0065] Because of the small diameter of the cylindrical filaments, their contact with the touch film can be approximated as line contact. During the touch film transport process, this line contact method reduces large-area friction on the touch film surface. Compared with surface contact support, line contact can reduce the heat generated by friction, reduce wear on the touch film surface, and thus better protect the surface quality of the touch film, avoiding defects such as scratches and indentations. When the touch film is placed on the cylindrical filaments, the filaments can evenly transfer the weight of the touch film to the conveyor roller shaft row 1 below. Although the diameter of the cylindrical filaments is small, through reasonable layout and quantity setting, it can be ensured that the touch film receives relatively uniform support force throughout the width direction, ensuring that the touch film remains flat during transport and does not sag or deform locally.

[0066] In this embodiment, the use of a first support belt 31 made of fine filaments significantly reduces the contact area between the first support belt 31 and the surface of the touch film through line contact support, thereby reducing the friction between them. The lower resistance and better support stability allow the equipment to transport the touch film at a higher speed, improving production efficiency while ensuring the quality of the touch film and meeting the needs of large-scale production. Because the cylindrical filaments offer little resistance to the movement of the roller shaft 11, the equipment does not require excessive energy to overcome the friction between the support components and the roller shaft 11 during operation. This not only reduces the equipment's energy consumption and operating costs but also aligns with the current trend of energy conservation and environmental protection.

[0067] In one embodiment, reference is made to Figure 1 The conveying roller shaft row 1 includes an outer frame, and the roller shaft 11 is installed in the outer frame; the outer frame includes a horizontal frame 2 arranged parallel to the roller shaft 11; the support belt includes a second support belt 32, one end of the second support belt 32 is fixed to the horizontal frame 2, and the other end extends toward the side where the roller shaft 11 is located, so that the main body of the second support belt 32 can rest on the roller shaft 11.

[0068] In this embodiment, one end of the second support belt 32 is fixed to the horizontal frame 2, ensuring that it can cover the gap between the horizontal frame 2 and the edge roller 11, thus guaranteeing a smooth transition of the touch film between the roller 11 and the horizontal frame 2. When the touch film moves from the roller 11 area to the vicinity of the horizontal frame 2, the second support belt 32 can provide additional support to prevent the touch film from lifting or wrinkling at the edge due to loss of support, ensuring that the touch film can pass smoothly through the entire conveying area.

[0069] In a specific implementation, in one example, the first support belt 31 and the second support belt 32 are combined. The first support belt 31 covers all the rollers 11 to provide support in the gap between the rollers 11. The second support belt 32 covers at least the gap between the horizontal frame 2 and the edge rollers 11 to ensure a smooth transition of the touch film between the rollers 11 and the horizontal frame 2.

[0070] In this design, the first support belt 31 is fixed at both ends by the lower fixing frame 4. The high tension allows it to fit tightly against the roller 11. This tight fit prevents the first support belt 31 from lifting the touch film too high, ensuring effective contact between the touch film and the roller 11. If the touch film is lifted too high, the contact area between the touch film and the roller 11 will decrease, resulting in insufficient friction and affecting the conveying function. This structural design of the first support belt 31 can effectively solve this problem and ensure the stability and reliability of the touch film conveying.

[0071] The first support belt 31 provides support in the gap between the roller 11 and the second support belt 32 provides support in the gap between the roller 11 and the horizontal frame 2. The combination of the two ensures that the touch film can be evenly and stably supported throughout the entire conveying process.

[0072] In one example, only the second support belt 32 is provided, which covers the gaps between all the rollers 11 and the gap between the edge rollers 11 and the horizontal frame 2.

[0073] In one embodiment, the second support strip 32 is a flat strip with a width of no more than 5cm and a thickness of no more than 2mm.

[0074] In this embodiment, since the second support belt 32 is fixed to the horizontal frame 2 at only one end and not at the other, its flat shape provides good stability and ensures stable support. The second support belt 32 rests on the roller 11, and its flat shape and flexibility allow it to adapt to the rotational movement of the roller 11. When the roller 11 rotates, relative sliding occurs between the second support belt 32 and the surface of the roller 11. However, due to its flat and thin structure, this sliding friction is small and does not significantly hinder the rotation of the roller 11. Simultaneously, the free end of the second support belt 32 can adaptively adjust according to the rotation of the roller 11 and the movement of the touch film, ensuring stable transition support for the touch film at all times.

[0075] In one embodiment, the support strip is made of polycarbonate, polymethyl methacrylate, or polytetrafluoroethylene.

[0076] All of the above materials have the advantages of smooth surface, low coefficient of friction, and good wear resistance. When the touch film slides on these surfaces, the resistance is small, which is conducive to the smooth transport of the touch film and reduces static electricity and wear caused by friction. At the same time, the above materials have sufficient strength and rigidity to provide stable and reliable support, ensuring that the touch film will not sag or deform due to insufficient support during transport.
