[0002] With people becoming more health-conscious, face masks have become an essential item in daily life, and the market demand for face masks has increased dramatically.
[0003] However, most masks made by existing equipment are flat and require users to bend them themselves before wearing them. Manually bent masks are not good at protecting people. Furthermore, existing equipment often pinches and pinches the nose bridge strip to create folds during mechanical shaping, which is also difficult to ensure that it fits the facial features of most people. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an intelligent flat mask machine that solves the problems mentioned in the background section.

The sliding plate is slidably connected to the upper surface of the workbench, and the receiving plate is slidably connected to the upper surface of the sliding plate. There are two sets of receiving plates, which are slidably connected to the left and right ends of the sliding plate, respectively. One end of the clamping spring is fixedly connected to the side wall of the sliding plate. When the receiving plate slides on the upper surface of the sliding plate, it compresses the clamping spring.

The push block is slidably connected to the side wall of the fixed box, the cylinder is fixedly connected to the upper surface of the support plate, and a piston rod is connected to the bottom of the cylinder.
[0008] According to the above technical solution, the piston rod passes through the support plate and is slidably connected at the point of penetration. The fixing plate is fixedly connected to the end of the piston rod away from the cylinder. The infrared emitter is fixedly connected to the bottom surface of the fixing plate.

[0010] According to the above technical solution, a feeding device to prevent masks from accumulating is provided above the workbench. The feeding device includes a trapezoidal plate, a push rod, a tightening spring, a guide rod, a sliding block, a reset spring, a striking rod, and a squeezing block. The trapezoidal plate is fixedly connected to the side wall of the fixed plate, and the push rod is slidably connected to the upper surface of the workbench. When the trapezoidal plate moves downward, it pushes the push rod to slide.
[0011] According to the above technical solution, a protrusion is fixed on the upper surface of the worktable, one end of the tension spring is fixedly connected to the side wall of the protrusion on the upper surface of the worktable, the other end of the tension spring is fixedly connected to the side wall of the push rod, the guide rod is fixedly connected to the side wall of the push rod, the guide rod passes through the sliding block and is slidably connected at the point of penetration, and the push rod slides to drive the guide rod to move.

When the sliding block slides to the pressing block, it is pushed by the pressing block and slides away from the pressing block, and stretches the return spring.
[0013] This invention provides an intelligent flat mask machine. It has the following beneficial effects: 1. This invention includes a conveying device that, during the shaping of the finished mask, supports the mask in conjunction with a fixed box, extrusion plate, support spring, and support column. This allows for greater flexibility in the support structure below the mask during shaping. When used with the mold, it automatically lifts the nose bridge strip, solving the problem that existing shaping molds cannot directly create a mask shape suitable for facial curves. After the main parts of the mask are cut and pressed, a sliding plate, receiving plate, and clamping spring convey the mask to the top of the shaping device. This prevents the conveyor belt from directly conveying the mask above the support column, which would otherwise cause it to jam and prevent it from reaching the designated shaping position. It also avoids manual contact with the mask by workers, ensuring hygiene during the shaping process and solving the problem of the mask being difficult to move directly above multiple sets of dense point supports.
[0014] 2. This invention includes a positioning device. When the mask is transported to the designated position, a sliding plate pushes a pusher block upwards, causing the mask to fall onto the support column at an angle and slide down the slope. This corrects the mask's position, preventing it from tilting when placed in the designated position, which could lead to misalignment during mask shaping and reduced mask production quality. This invention solves the problem that masks with large overall force-bearing area and small mass may tilt due to air resistance when falling directly. During mask transport, a fixing plate, infrared emitter, laser sensor, and controller work together to automatically push the shaping mold downwards with a cylinder, shaping the mask and improving the efficiency of mask shaping. This solves the problem of low efficiency when workers manually control the shaping mold.
[0015] 3. This invention includes a feeding device. Before shaping the mask, a trapezoidal plate and a tension spring push the push rod to the other side of the fixed box. After shaping, the spring's restoring force causes the push rod to slide, sweeping away the shaped mask. This prevents the mask from accumulating on top of the support column, affecting the shaping effect, and solves the problem of needing staff to remove the mask after shaping. When correcting and positioning the mask, a guide rod, sliding block, return spring, striking rod, and squeezing block strike the fixed box, causing it to shake. This shaking causes the mask on the support column to bounce slightly, facilitating the positioning device to correct the mask's position. This prevents the mask's corners from getting stuck in the gaps between the support columns, making adjustment difficult and solving the problem of mask corners easily getting stuck in the gaps between the support columns.

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-7One embodiment of the present invention is as follows: an intelligent flat mask machine includes a worktable 1, a support leg 2 fixed to the bottom surface of the worktable 1, a conveyor belt 3 fixed to the upper surface of the worktable 1, a folding and pressing mechanism 4 fixed to the upper surface of the worktable 1, the folding and pressing mechanism 4 being disposed above the conveyor belt 3, and an unwinding device 5 fixed to the upper surface of the worktable 1. Mask fabric rolls, nose bridge strips, and ear loops are respectively wound onto different winding rollers of the unwinding device 5 and wound up. The unwound ends of the mask fabric rolls, nose bridge strips, and ear loops are respectively passed through the folding and pressing machine. The side wall of the structure 4 is pulled to the bottom of the folding and pressing mechanism 4. When the equipment is started, the unwinding device 5 intermittently feeds the mask fabric roll, nose bridge strip and mask ear loops. The upper surface of the workbench 1 is fixed with a support plate 6. A transmission device is set above the workbench 1 to prevent workers from touching the mask. The fed mask fabric roll, nose bridge strip and mask ear loops are above the conveyor belt 3. The folding and pressing mechanism 4 cuts and presses the mask fabric roll, nose bridge strip and mask ear loops above the conveyor belt 3 respectively. The conveyor belt 3 conveys the cut and pressed mask to the top of the transmission device.
[0020] The conveying device includes a sliding plate 71, a receiving plate 72, a clamping spring 73, a fixing box 74, a pressing plate 75, a support spring 76, and a support column 77. The sliding plate 71 is slidably connected to the upper surface of the workbench 1, and the receiving plate 72 is slidably connected to the upper surface of the sliding plate 71. When the mask falls completely onto the receiving plate 72, the sliding plate 71 is manually pushed, and it slides on the upper surface of the workbench 1. Two sets of receiving plates 72 are provided, slidably connected to the left and right ends of the sliding plate 71 respectively. When the cover is cut and pressed, as it is conveyed by the conveyor belt 3 to the top of the receiving plate 72, the sliding plate 71 slides, causing the receiving plate 72 to move as well. One end of the clamping spring 73 is fixedly connected to the side wall of the sliding plate 71, and the other end of the clamping spring 73 is fixedly connected to the side wall of the receiving plate 72. When the receiving plates 72 move away from each other, the receiving plate 72 slides towards the side wall of the sliding plate 71, compressing the clamping spring 73. The fixing box 74 is fixedly connected to the upper surface of the workbench 1. When the sliding plate 71 slides to the position of the fixing box... When the side walls of the fixed box 74 are in contact, the two sets of receiving plates 72 move away from each other until they slide out of the area above the fixed box 74. The extrusion plate 75 is fixedly connected to the side wall of the fixed box 74. When the receiving plate 72 moves with the sliding plate 71 to the extrusion plate 75, the extrusion plate 75 pushes the receiving plate 72 to slide away from the extrusion plate 75. The support spring 76 is fixedly connected to the bottom surface of the inner wall of the fixed box 74. The support column 77 is fixedly connected to the end of the support spring 76 away from the fixed box 74. When the sliding plate 71 slides to the side wall of the fixed box 74, the two sets of receiving plates 72 move away from each other until they slide out of the area above the fixed box 74. When the sidewalls of 74 are attached, the two sets of receiving plates 72 move away from each other until they slide out of the area above the fixed box 74. When the conveying device shapes the finished mask, it works with the fixed box 74, the extrusion plate 75, the support spring 76 and the support column 77 to support the mask, so that the support under the mask can be more flexible when shaping. When it works with the mold to shape the mask, it can automatically lift the nose bridge strip, which solves the problem that the existing shaping mold 87 is difficult to directly shape into a mask shape that fits the facial curve. After the main parts of the mask are cut and pressed, the sliding plate 71, receiving plate 72 and clamping spring 73 work together to transport the mask to the top of the shaping device. This avoids the conveyor belt 3 from directly transporting the mask to the top of the support column 77 and getting stuck, which would make it difficult for the mask to reach the designated position for shaping. It also avoids workers from manually touching the mask, which further ensures hygiene during the mask shaping process and solves the problem that the mask is difficult to move directly above multiple sets of dense point supports.
[0021] In this embodiment, the mask fabric roll, nose bridge strip, and ear loops are wound onto different take-up rollers of the unwinding device 5 and wound up. The unwound ends of the mask fabric roll, nose bridge strip, and ear loops are pulled below the folding and pressing mechanism 4 through the side wall. When the equipment is started, the unwinding device 5 intermittently releases the mask fabric roll, nose bridge strip, and ear loops. The released mask fabric roll, nose bridge strip, and ear loops are above the conveyor belt 3. The folding and pressing mechanism 4 cuts and presses the mask fabric roll, nose bridge strip, and ear loops above the conveyor belt 3. The conveyor belt 3 transports the cut and pressed masks to the top of the transmission device.
[0022] When the mask is cut and pressed, it is conveyed by conveyor belt 3 to the receiving plate 72. The mask falls completely onto the receiving plate 72. The sliding plate 71 is manually pushed, and it slides on the upper surface of the workbench 1. The sliding plate 71 moves the receiving plate 72. When the receiving plate 72 moves to the pressing plate 75, the pressing plate 75 pushes the receiving plate 72 away from the pressing plate 75. As the two sets of receiving plates 72 slide away from the pressing plate 75, they move away from each other. When the receiving plates 72 move away from each other, they slide against the side wall of the sliding plate 71, compressing the clamping spring 73. When the sliding plate 71 slides to be in contact with the side wall of the fixing box 74, the two sets of receiving plates 72 move away from each other until they slide out of the area above the fixing box 74. The mask, due to inertia, does not move with the receiving plate 72. When the receiving plate 72 is pulled out from under the mask, the mask falls due to gravity and lands above the support column 77. During the shaping of the mask, pressure is applied from top to bottom. Different parts of the support column 77 are subjected to different pressures, which also applies pressure to the support spring 76, pushing the support spring 76 to compress. The elastic force of the support spring 76 when compressed applies a pushing force to the support column 77. The support column 77, under the pushing force, applies pressure to the mask, making the mask fit more tightly to the mold above it. When the mask shaping is completed, the sliding plate 71 is pushed to reset the sliding plate 71. When the sliding plate 71 slides away from the fixed box 74, the receiving plate 72 is no longer pushed by the extrusion plate 75, but is simultaneously pushed by the restoring force of the clamping spring 73. It also slides on the upper surface of the sliding plate 71 to reset, receiving and clamping the next mask to prevent it from falling.
[0023] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a positioning device for convenient correction is provided above the workbench 1. The positioning device includes a push block 81, a cylinder 82, a fixing plate 83, an infrared emitter 84, a laser sensor 85, a controller 86, and a molding die 87. The push block 81 is slidably connected to the side wall of the fixing box 74. When the sliding plate 71 slides to the push block 81, the sliding plate 71 pushes the push block 81 upward. When the push block 81 slides to the uppermost position under the pushing force of the sliding plate 71, it may... The tilted front end of the mask is pushed upwards, lifting one end of the mask and correcting its position. Cylinder 82 is fixedly connected to the upper surface of support plate 6. A piston rod is connected to the bottom of cylinder 82, passing through support plate 6 and slidably connected at the point of penetration. Fixing plate 83 is fixedly connected to the end of the piston rod away from cylinder 82. Infrared emitter 84 is fixedly connected to the bottom surface of fixing plate 83. Laser sensor 85 is fixedly connected to the upper surface of worktable 1. Controller 86 is fixedly connected to the side wall of worktable 1. Sensor 85 is electrically connected to controller 86. When the mask falls from conveyor belt 3 onto receiving plate 72, it is blocked between infrared emitter 84 and laser sensor 85. Laser sensor 85 cannot receive the infrared light emitted by infrared emitter 84 and sends an electrical signal to controller 86. Controller 86 is electrically connected to cylinder 82. Controller 86 sends different commands to cylinder 82 according to the sequence of received signals, causing cylinder 82 to start or reset, pushing shaping mold 87 to shape the mask. Shaping mold 87 is fixedly connected to the bottom surface of fixed plate 83. When the positioning device transports the mask to the designated position, it works with sliding plate 71 to push push block 81 to slide upward, so that the mask is tilted when it falls onto support column 77 and slides down the slope, correcting the position of the mask. This prevents the mask from being crooked when placed in the designated position, which would cause the mask shaping position to shift and reduce the quality of mask production. This solves the problem that the mask has a large overall force-bearing area and a small mass, and may be crooked due to air resistance when falling directly. When conveying masks, the cylinder 82 automatically pushes the shaping mold 87 downward to shape the mask in conjunction with the fixing plate 83, infrared emitter 84, laser sensor 85 and controller 86, thereby improving the efficiency of mask shaping and solving the problem of low efficiency in shaping masks by manual control of the shaping mold 87.
[0024] A material feeding device to prevent mask accumulation is installed above the workbench 1. The material feeding device includes a trapezoidal plate 91, a push rod 92, a tensioning spring 93, a guide rod 94, a sliding block 95, a return spring 96, a striking rod 97, and a pressing block 98. The trapezoidal plate 91 is fixedly connected to the side wall of the fixed plate 83. When the fixed plate 83 moves downward, it also drives the trapezoidal plate 91 to move downward. The push rod 92 is slidably connected to the upper surface of the workbench 1. When the trapezoidal plate 91 moves to the push rod 92, the trapezoidal plate 91 pushes the push rod 92 to slide towards the support plate 6. A protrusion is fixed on the upper surface of the workbench 1, and one end of the tensioning spring 93 is fixedly connected to the protrusion on the upper surface of the workbench 1. The other end of the tension spring 93 is fixedly connected to the side wall of the push rod 92. When the push rod 92 slides towards the support plate 6, it stretches the tension spring 93. When the mask is shaped and the cylinder 82 drives the fixed plate 83 to move upward and reset, the push rod 92 is no longer pushed by the trapezoidal plate 91, but is reset by the restoring tension of the tension spring 93. When the push rod 92 resets, it sweeps away the shaped mask on the support column 77. The guide rod 94 is fixedly connected to the side wall of the push rod 92. When the push rod 92 slides, it drives the guide rod 94 to move. The guide rod 94 passes through the sliding block 95 and is slidably connected at the point of penetration. The movement of the guide rod 94 drives the sliding block 95 to move. The sliding block 95 is slidably connected to the upper surface of the worktable 1. One end of the return spring 96 is fixedly connected to the side wall of the push rod 92, and the other end of the return spring 96 is fixedly connected to the side wall of the sliding block 95. The striking rod 97 is fixedly connected to the side wall of the sliding block 95 near the return spring 96. The pressing block 98 is fixedly connected to the upper surface of the worktable 1. When the sliding block 95 slides to the pressing block 98, the pressing block 98 pushes the sliding block 95 to slide away from the push rod 92, while stretching the return spring 96. The push rod 92 drives the sliding block 95 to continue sliding. When the sliding block 95 slides to the point where it is disengaged from the pressing block 98, the sliding block 95 is no longer compressed. The pushing force of block 98, simultaneously subjected to the restoring tension of return spring 96, slides towards push rod 92. Sliding block 95 drives striking rod 97 towards fixed box 74, impacting fixed box 74 and causing it to shake. Before shaping the mask, the feeding device, in conjunction with trapezoidal plate 91 and tension spring 93, pushes push rod 92 to the other side of fixed box 74. After shaping, the restoring elasticity of tension spring 93 causes push rod 92 to slide, sweeping away the shaped mask. This prevents the mask from accumulating above support column 77, affecting the shaping effect, and solves the problem of needing staff to remove the mask after shaping. When the mask is being corrected and positioned, the guide rod 94, sliding block 95, return spring 96, tapping rod 97, and squeezing block 98 are used to tap the fixing box 74, causing the fixing box 74 to vibrate. The vibration of the fixing box 74 causes the mask on the support column 77 to bounce slightly, which makes it easier for the positioning device to correct the position of the mask. This avoids the corners of the mask getting stuck in the gaps of the support column 77, making it difficult to adjust, and solves the problem that the corners of the mask are easy to get stuck in the gaps of the support column 77.
[0025] In this embodiment, during operation: the sliding plate 71 slides towards the fixed box 74. When the sliding plate 71 slides to the push block 81, the side of the sliding plate 71 slides against the inclined surface of the push block 81, pushing the push block 81 upwards. When the sliding plate 71 slides to fit against the side wall of the fixed box 74, the push block 81 slides to its uppermost position under the pushing force of the sliding plate 71, pushing the potentially misaligned front end of the mask upwards, lifting one end of the mask, and correcting its position. When the mask falls from the conveyor belt 3 onto the receiving plate 72, it blocks the infrared emitter 84 and the laser sensor 85. The laser sensor 85 cannot receive the infrared rays emitted by the infrared emitter 84 and sends the first wave of electrical signal to the controller 86. When the controller 86 receives the first wave of electrical signal, it controls the cylinder 82 to prepare. When the receiving plate 72 slides with the mask into the fixed box... Above 74, when the mask is lowered, the laser sensor 85 receives the infrared light emitted by the infrared emitter 84 again and sends a second electrical signal to the controller 86. After receiving the second electrical signal, the controller 86 controls the cylinder 82 to start. The cylinder 82 pushes the fixed plate 83 downward through the piston rod. The fixed plate 83 drives the shaping mold 87 downward to shape the mask above the support column 77. When the mask is shaped and the sliding plate 71 is reset, the push block 81 is no longer pushed by the sliding plate 71 and slides downward under its own gravity. During the reset process, the sliding plate 71 briefly blocks the infrared light emitted by the infrared emitter 84. When the laser sensor 85 can no longer receive the infrared light, it sends a third electrical signal to the controller 86. After receiving the third electrical signal, the controller 86 controls the cylinder 82 to retract the piston rod.
[0026] When the fixed plate 83 moves downward, it also drives the trapezoidal plate 91 downward. When the trapezoidal plate 91 moves to the push rod 92, the inclined surface of the trapezoidal plate 91 slides against the side of the push rod 92, pushing the push rod 92 to slide towards the support plate 6. When the push rod 92 slides towards the support plate 6, it stretches the tension spring 93. As the push rod 92 slides, it drives the guide rod 94 to move. The movement of the guide rod 94 drives the sliding block 95 to slide. When the sliding block 95 slides to the pressing block 98, the side of the sliding block 95 slides against the inclined surface of the pressing block 98. The pressing block 98 pushes the sliding block 95 to slide away from the push rod 92, while stretching the return spring 96. The push rod 92 drives the sliding block 95 to continue moving forward. As the sliding block 95 slides to the point where it is disengaged from the pressing block 98, it is no longer pushed by the pressing block 98 and is simultaneously pulled by the restoring spring 96. It slides towards the push rod 92. The sliding block 95 drives the striking rod 97 to move towards the fixed box 74, impacting the fixed box 74 and causing it to shake. The shaking of the fixed box 74 causes the mask on the support column 77 to bounce slightly, facilitating the positioning device to correct the position of the mask. When the mask is shaped, the cylinder 82 drives the fixed plate 83 to move upward and reset. The push rod 92 is no longer pushed by the trapezoidal plate 91 and is simultaneously reset by the restoring spring 93. When the push rod 92 resets, it sweeps away the shaped mask on the support column 77.
