[0030] like Figures 1-5 As shown, this embodiment provides a mask fabric cutting device, including: a machine base 1, a feeding platform 2, a discharging platform 3, a cutting mechanism 4, and two protective components 5; the machine base 1 is provided with a conveyor belt for conveying the mask fabric, the feeding platform 2 is provided at the initial end of the conveyor belt, the discharging platform 3 is provided at the end of the conveyor belt, and the cutting mechanism 4 is movably provided on the feeding platform 2;

[0031] The cutting mechanism 4 includes a gantry frame 401, a drive assembly, a slider 402, a lifting assembly 403, and a cutting component 404. The gantry frame 401 is movably mounted on the feeding table 2. The gantry frame 401 is provided with a metal slide rail 405 located directly above the conveyor belt. The slider 402 is slidably mounted on the metal slide rail 405. The drive assembly is mounted on the gantry frame 401, and its drive end is connected to the slider 402. The lifting assembly 403 is mounted on the lower side of the slider 402. The cutting component 404 is connected to the lifting end of the lifting assembly 403.

[0032] Two protective components 5 are respectively disposed on both sides of the slider 402 along the sliding direction of the slider 402. Each protective component 5 includes an acrylic bracket 501, an elastic protective element 502, and a buckle 503. The acrylic bracket 501 is detachably installed on the slider 402, and the buckle 503 is disposed on the gantry frame 401. One end of the elastic protective element 502 is connected to the acrylic bracket 501, and the other end is snapped into the buckle 503. The elastic protective element 502 covers the underside of the metal slide rail 405 and is used to receive metal materials that fall off during the movement and friction between the slider 402 and the metal slide rail 405. The elastic protective element 502 has a contracted state and an extended state, and the elastic protective element 502 repeatedly switches between the contracted state and the extended state during the movement of the slider 402.

[0033] Based on the above scheme, the main body of the device includes a machine base 1, a feeding platform 2, a discharging platform 3, a cutting mechanism 4, and two key protective components 5. The machine base 1 is equipped with a conveyor belt responsible for transporting the mask fabric from the feeding platform 2 to the discharging platform 3. The cutting mechanism 4 is cleverly designed on the feeding platform 2, possessing mobility to adapt to different cutting needs. This mechanism consists of a gantry frame 401, a drive assembly, a slider 402, a lifting assembly 403, and a cutting component 404. The gantry frame 401 is movably mounted on the feeding platform 2 and has a metal slide rail 405. The slider 402 slides along this slide rail 405 and is driven by the drive assembly. The lifting assembly 403 is installed below the slider 402 and connected to the cutting component 404. When the slider 402 moves to a predetermined position, the lifting assembly 403 drives the cutting component 404 to descend and perform the cutting task. Most importantly, this device innovatively introduces protective components 5 to prevent metal substances from falling off during the cutting process and contaminating the mask fabric. Two protective components 5 are respectively disposed on both sides of the slider 402, arranged along its sliding direction. Each protective component 5 includes an acrylic bracket 501, an elastic protective element 502, and a buckle 503. The acrylic bracket 501 is detachably fixed to the slider 402, and the buckle 503 is disposed on the gantry frame 401. One end of the elastic protective element 502 is connected to the acrylic bracket 501, and the other end is snapped into the buckle 503, forming a complete coverage of the area under the metal slide rail 405. When the slider 402 slides on the metal slide rail 405, the elastic protective element 502 can flexibly switch between a contracted state and an extended state, effectively catching any metal particles that may fall off during the friction between the slider 402 and the metal slide rail 405, thereby preventing these particles from falling onto the mask cloth and ensuring the cleanliness and safety of the mask cloth.

[0034] Furthermore, the design of the protective component 5 not only enhances the durability of the equipment and reduces direct friction between the slider 402 and the metal guide rail 405, extending the equipment's service life, but also improves production efficiency and flexibility. The mobility of the cutting mechanism 4 allows for precise cutting of the mask fabric at different positions, while the adaptability and convenience of the elastic protective component 502 ensures effective protection during various cutting processes. In summary, this mask fabric cutting device, through the innovative design of the protective component 5, effectively solves the problem of metal contamination during the mask fabric cutting process, improves production efficiency and product quality, and represents a significant advancement in the mask fabric production field.

[0035] Furthermore, the elastic protective component 502 is provided with a ring 504 that engages with the buckle 503. The ring 504, as part of the elastic protective component 502, is cleverly designed to naturally fit the buckle 503. When the elastic protective component 502 on the acrylic bracket 501 is stretched and engaged with the buckle 503 on the gantry 401, the ring 504 tightly wraps around the buckle 503, forming a stable connection point. This design not only ensures the stability of the elastic protective component 502 during the cutting process, preventing it from falling off due to vibration or force generated by the movement of the slider 402, but also makes the installation and disassembly process more convenient. The material of the ring 504 is consistent with that of the elastic protective component 502, ensuring that it maintains sufficient strength while also possessing good elasticity and wear resistance. Thus, even after prolonged use and repeated stretching and shrinking, the ring 504 can maintain its good shape and performance, thereby ensuring the continued effectiveness of the protective component 5. The design of the engagement between the ring 504 and the clip 503 also takes into account the need for easy disassembly. When it is necessary to replace or maintain the elastic protective component 502, the operator can easily remove the elastic protective component 502 from the acrylic bracket 501 by disengaging the connection between the ring 504 and the clip 503, without the need for additional tools or equipment. This design not only improves work efficiency but also reduces the difficulty of operation, making the entire cutting device easier to maintain and manage.

[0036] Furthermore, the acrylic bracket 501 has a first locking hole 505, and the slider 402 has a second locking hole 4022 corresponding to the position of the first locking hole 505. Fasteners 506 pass through the first locking hole 505 and the second locking hole 4022 sequentially to fix the acrylic bracket 501 to the side of the slider 402. The first locking holes 505 are formed on the acrylic bracket 501, and their position and number are carefully designed according to the shape and size of the slider 402 to ensure that the acrylic bracket 501 can be stably fixed to the side of the slider 402. Correspondingly, the second locking holes 4022 on the slider 402 correspond one-to-one with the positions of the first locking holes 505, providing a channel for the fasteners 506 to pass through and lock. In actual installation, the operator can place the acrylic bracket 501 on the side of the slider 402, aligning the first locking holes 505 and the second locking holes 4022. Then, by selecting appropriate fasteners 506 (such as bolts, nuts, etc.), passing them sequentially through the first locking hole 505 and the second locking hole 4022, and tightening the fasteners 506, the acrylic bracket 501 is firmly fixed to the slider 402. This fixing method not only ensures the stability of the acrylic bracket 501 during the movement of the slider 402, but also prevents loosening or falling off due to vibration or external force. In addition, this design also provides convenience for disassembling the acrylic bracket 501 from the slider 402. When maintenance or replacement of the elastic protective part 502 is required, the operator only needs to loosen the fasteners 506 to easily remove the acrylic bracket 501 from the slider 402 without damaging any parts, which not only improves work efficiency but also reduces maintenance costs.

[0037] In some embodiments, both sides of the slide rail 405 are provided with arc-shaped guide portions 4051, and both inner walls of the slider 402 are provided with arc-shaped guide grooves 4021 that cooperate with and guide the arc-shaped guide portions 4051. During the cutting process, the slider 402 needs to slide smoothly and precisely on the slide rail 405 to ensure that the cut piece 404 can be accurately positioned at the predetermined position on the mask fabric. However, due to minor errors in the manufacturing and assembly process, as well as wear after long-term use, the fit between the slider 402 and the slide rail 405 may deviate, thus affecting the cutting accuracy. To solve this problem, this embodiment designs arc-shaped guide portions 4051 on both sides of the slide rail 405. These arc-shaped guide portions 4051 not only provide a smoother sliding surface for the slider 402, but also guide the slider 402 to maintain the correct direction during movement through their unique shape design. Correspondingly, the two inner walls of the slider 402 are provided with arc-shaped guide grooves 4021 that match the arc-shaped guide part 4051. These guide grooves can fit tightly against the arc-shaped guide part 4051 to ensure the stability and accuracy of the slider 402 when it moves on the slide rail 405.

[0038] Furthermore, the design of the arc-shaped guide portion 4051 and the arc-shaped guide groove 4021 also takes into account the dynamic balance of the slider 402 during movement. Because the arc-shaped guide portion 4051 has a certain curvature, it can provide additional support force when the slider 402 moves, helping the slider 402 maintain a stable posture. This not only improves the operational stability of the slider 402 but also extends the service life of the slide rail 405 and the slider 402.

[0039] In further optimized design of the mask fabric cutting device, to enhance the stability and flexibility of the cutting mechanism 4, two movable components are optionally introduced, forming a sliding connection with two symmetrically arranged guide rails 101 on the machine base 1. This design allows the gantry 401 to move more smoothly and accurately along the guide rails 101, thereby ensuring that the cutting piece 404 can be accurately positioned at the predetermined position on the mask fabric. Specifically, each movable component is designed with a sliding structure that matches the guide rail 101 to ensure that the sliding connection between it and the guide rail 101 is both smooth and reliable. When the cutting mechanism 4 needs to move, the two movable components slide simultaneously along their respective guide rails 101, thereby driving the gantry 401 and the cutting piece 404 on it to move together. The guide rails 101 are symmetrically arranged on the machine base 1, providing stable support and guidance for the movable components. This symmetrical design not only helps maintain the balance of the cutting mechanism 4, but also reduces vibration and deviation during movement, thereby improving cutting accuracy. The two ends of the gantry 401 are respectively connected to two moving components, which ensures the stability and rigidity of the gantry 401 during movement. When the moving components slide along the guide rail 101, the gantry 401 will move accordingly, while maintaining the stability and accuracy of its overall structure.

[0040] Specifically, the moving component includes a moving block 6, a motor mover mounted on the moving block 6, and a motor stator mounted on the guide rail 101. The motor stator and the motor mover cooperate to drive the moving block 6 to move along the guide rail 101. The moving block 6 is connected to the gantry frame 401. The motor stator, as the drive source, is fixedly mounted on the guide rail 101 to provide power to the moving block 6. The motor mover is mounted on the moving block 6 and cooperates with the motor stator. When the motor stator is energized, it generates a magnetic field that attracts or repels the motor mover, thereby driving the moving block 6 to move along the guide rail 101. The guide rail 101 serves as the sliding track for the moving block 6, and its design must ensure that the moving block 6 can move smoothly and accurately along it. The guide rail 101 can adopt a linear guide, a V-shaped guide, or a ball bearing guide to improve sliding performance and accuracy. As a key component connecting the motor mover and the gantry 401, the movable block 6 must be designed with sufficient strength and rigidity to withstand the load and vibration during the cutting process. Simultaneously, the movable block 6 must also achieve a reliable connection with the gantry 401 to ensure the stability and accuracy of the gantry 401 during movement.

[0041] In practical applications, when the cutting mechanism 4 needs to be moved, the motor stator is energized to generate a magnetic field, which drives the motor mover to move the moving block 6 along the guide rail 101. Because the motor drive has high precision and controllability, the position of the moving block 6 can be precisely controlled, thereby ensuring that the cutting part 404 can be accurately positioned on the predetermined position on the mask cloth.

[0042] To further optimize the movement performance of the moving block 6 and reduce friction, multiple air-float components are cleverly designed into the inner wall surface of the moving block 6. These air-float components generate a thin air film during operation, enabling non-contact support and sliding between the moving block 6 and the guide rail 101, thereby greatly reducing frictional resistance and wear. Specifically, the air-float components typically utilize compressed gas (such as air) injected through tiny channels onto the contact surface between the moving block 6 and the guide rail 101, forming a stable air film. This air film not only effectively isolates the moving block 6 from direct contact with the guide rail 101, reducing friction and wear, but also provides stable support, ensuring the smooth movement of the moving block 6 on the guide rail 101. The design of the air-float components needs to consider multiple factors, including the gas injection pressure, flow rate, channel size, and distribution, to ensure that the formed air film is both stable and uniform. Simultaneously, to maintain the stability of the air film, appropriate gas sealing structures are usually required on the moving block 6 or the guide rail 101 to prevent gas leakage.

[0043] Meanwhile, an air storage chamber is formed inside the movable block 6, and an air inlet connector 7 and multiple air outlet connectors 8 are provided on the outer wall of the movable block 6. One end of the air inlet connector 7 is connected to the air supply equipment, and the other end is connected to the air storage chamber. One end of the air outlet connector 8 is connected to the air storage chamber, and the other end is connected to the air flotation component. The air storage chamber is located inside the movable block 6 to store compressed gas supplied by the air supply equipment. This design not only ensures that the air flotation component can obtain a stable and continuous gas supply when needed, but also improves the gas utilization efficiency and reduces energy waste. The air inlet connector 7 acts as a bridge connecting the internal air storage chamber of the movable block 6 and the external air supply equipment. Its design must ensure that the gas can enter the air storage chamber smoothly and efficiently. In practical applications, one end of the air inlet connector 7 is usually connected to the output end of the air supply equipment, and the other end is connected to the air storage chamber through a channel inside the movable block 6. The air outlet connectors 8 are responsible for delivering the gas in the air storage chamber to each air flotation component. To ensure uniform and stable gas distribution to each air flotation component, multiple gas outlet connectors 8 are cleverly arranged on the outer wall of the moving block 6. Each gas outlet connector 8 forms an independent gas supply channel between the gas storage chamber and the air flotation component. This design not only ensures a sufficient and stable gas supply to the air flotation component but also improves the reliability and durability of the entire air flotation system. In practical applications, when the gas supply equipment is started, compressed gas enters the gas storage chamber through the gas inlet connector 7 and is stored there. When the moving block 6 needs to be moved, the gas in the gas storage chamber is delivered to each air flotation component through the gas outlet connectors 8, forming a stable gas film that provides support and sliding for the moving block 6.

[0044] As an optional specific implementation, the guide rail 101 has a limiting groove 102 on its side, and the moving block 6 has a limiting part 601 protruding from it, which cooperates with the limiting groove 102 for limiting. The limiting groove 102 is usually designed to be elongated, extending along the length of the guide rail 101. This design not only provides a clear movement path for the moving block 6, but also restricts the movement of the moving block 6 in the lateral and vertical directions, thereby ensuring the stability of the moving block 6 on the guide rail 101. The limiting part 601 on the moving block 6 forms a tight fit with the limiting groove 102. The limiting part 601 is usually designed as a protruding structure that matches the shape of the limiting groove 102. When the moving block 6 moves along the guide rail 101, the limiting part 601 will be tightly embedded in the limiting groove 102, contacting the side wall of the limiting groove 102, thereby restricting the movement of the moving block 6 in the lateral and vertical directions. This limiting design not only improves the stability of the moving block 6 on the guide rail 101, but also ensures the accuracy of the moving block 6 during movement. Due to the tight fit between the limiting groove 102 and the limiting part 601, the moving block 6 is not prone to deviation or shaking during movement, thereby ensuring the precise positioning of the cutting mechanism 4 on the mask fabric.

[0045] In the design of the mask fabric cutting device, the design of the machine 1 and the feeding table 2 have been carefully considered in order to improve the flatness and stability of the mask fabric before cutting and to ensure that the mask fabric can smoothly enter the cutting area.

[0046] First, at least two flattening rollers 10 are installed on machine 1. These two flattening rollers 10 are typically installed at appropriate positions along the mask fabric's transport path. As the mask fabric passes through, they apply pressure to it, flattening it. This design not only helps eliminate wrinkles and unevenness that may occur during transport but also improves the stability and precision of the mask fabric during cutting. The material and hardness of the flattening rollers 10 are usually selected based on the material and thickness of the mask fabric to ensure that appropriate pressure is applied without damaging its surface. Simultaneously, the arrangement and spacing of the flattening rollers 10 also need to be adjusted according to the width and transport speed of the mask fabric to ensure a uniform flattening effect across the entire mask fabric.

[0047] Secondly, a feed roller 9 is installed on the feeding table 2. The main function of the feed roller 9 is to guide the mask fabric smoothly into the cutting area. When the mask fabric is placed on the feeding table 2, the feed roller 9 rolls it forward, gradually guiding it into the working range of the cutting mechanism 4. This design not only helps reduce the resistance and friction of the mask fabric during transmission but also improves the accuracy and stability of the mask fabric entering the cutting area. The rotational speed and direction of the feed roller 9 usually need to be adjusted according to the transmission speed of the mask fabric and the working rhythm of the cutting mechanism 4 to ensure that the mask fabric can enter the cutting area smoothly and stably. At the same time, the surface of the feed roller 9 also needs to be kept smooth and flat to avoid damaging the mask fabric or affecting its flatness.
