[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Please refer to the attached document. Figures 1-5 This application provides a cup-shaped mask production equipment 100 for producing cup-shaped masks.

[0026] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the cup-shaped mask equipment 100 includes a first frame 10, a first cutting component 20, a first fabric device 30, a second fabric device 40, a welding module 50, and a finished product cutting module 60; the first frame 10 extends in the front-rear direction, the first cutting component 20 is disposed at the rear end of the first frame 10, the first cutting component 20 is connected to the first frame 10, and the first cutting component 20 is used to cut the rolled mask fabric into the first mask fabric, the first mask fabric is in sheet form, so as to facilitate the adjustment of the rolled mask fabric into sheet form.

[0027] The first fabric device 30 includes a first conveying component 31, a hot pressing module 32, and a meltblown fabric module 33. The first conveying component 31 is located in front of the first cutting component 20 and sequentially passes the first mask fabric output from the first cutting component 20 through the hot pressing module 32 and the meltblown fabric module 33. The hot pressing module 32 is used to hot press the first mask fabric into shape. The meltblown fabric module 33 is used to stack meltblown fabric on the first mask fabric to form a second mask fabric, so that the first fabric device 30 integrates the conveying function, the hot pressing function, and the meltblown fabric stacking function.

[0028] The second fabric device 40 includes a second frame 41, a second conveying component 42, and a lifting module 43. The second frame 41 extends in the left-right direction and is located on the right side of the first frame 10. The second conveying component 42 is connected to the second frame 41 and is used to convey a third fabric, which is in sheet form. The third fabric conveyed by the second conveying component 42 is lifted upward by the lifting module 43 and stacked onto the second mask fabric in the up-down direction to form a fourth fabric. The fourth fabric is further conveyed by the first conveying component 31, realizing the vertical spatial convergence of multiple fabrics on the conveyor line. The three-dimensional layout effectively reduces the floor space and avoids the offset, wrinkles, or contamination of the fabric during long-distance horizontal conveying or manual transfer, ensuring the accuracy of fabric stacking.

[0029] The welding module 50 is located in front of the lifting module 43 and performs ultrasonic welding on the fourth fabric conveyed by the first conveying component 31 to form the fifth fabric. The finished product cutting module 60 is located in front of the welding module 50 and performs final cutting on the fifth fabric conveyed by the first conveying component 31 to form the corresponding cup-shaped mask. This ensures that the multiple layers of fabric are in a relatively fixed position after being stacked, and will not be displaced due to long-term conveying, thereby effectively improving the welding strength and the dimensional accuracy and product yield of the cup-shaped mask.

[0030] At this point, by highly integrating the first fabric device 30 (composed of the first cutting component 20, the hot pressing module 32, and the meltblown fabric module 33), the second fabric device 40 (composed of the second conveying component 42 and the lifting module 43), the welding module 50, and the finished product cutting module 60 into the same equipment, a fully automated production line is formed. From the cutting, hot pressing, and meltblown fabric stacking of rolls of fabric, to the automatic lifting and stacking, ultrasonic welding, and final product cutting of sheet fabrics, the entire process is completed automatically and continuously. This avoids the need for manual intervention to transfer semi-finished products when each process is independently arranged, eliminates the time spent on manual transfer and waiting, reduces labor costs, and improves the production efficiency of the cup-shaped mask equipment for 100 pairs of cup-shaped masks. Please refer to the attached document. Figures 1-5In this embodiment, the lifting module 43 is housed in the first frame 10; the hot pressing module 32, the meltblown fabric module 33, the lifting module 43, the welding module 50, and the finished product cutting module 60 are arranged sequentially along the forward direction of the first conveying component 31, forming a linear sequential arrangement, so that once the first mask fabric enters the first conveying component 31, it will be conveyed forward according to the process sequence without changing the conveying path or leaving the production line, forming a highly continuous production flow.

[0031] The second conveying component 42 is located outside the first conveying component 31. The second conveying component 42 is arranged perpendicular to the extension direction of the first conveying component 31, which facilitates the feeding and buffering of the sheet-like third fabric and avoids interference with the main logistics line.

[0032] Please refer to the attached document. Figures 1-3 In this embodiment, the first cutting assembly 20 includes a first cutting module 21 and a first transfer module 22. The first transfer module 22 includes a first linear movement module 221 and a first transfer arm 222. The first linear movement module 221 is connected to the first frame 10 and drives the first transfer arm 222 to move in the front-back direction. The first transfer arm 222 clamps the rolled-up mask fabric and moves it forward to the first cutting module 21 to adjust the length of the cut mask fabric. At this time, the operator can quickly adjust the cutting length according to the specifications of different mask lengths by adjusting the displacement of the first transfer arm 222, without changing the cutter or adjusting complex mechanical stops, thus improving the adaptability of the first cutting assembly 20 to different product specifications. Optionally, the first linear movement module 221 is a synchronous belt linear movement module.

[0033] The first cutting module 21 includes a first cutting section 211 and a second linear motion module 212. The second linear motion module 212 is connected to the first frame 10 and moves in the left-right direction. The first cutting section 211 is connected to the moving end of the second linear motion module 212 and, driven by the moving end of the second linear motion module 212, cuts the mask fabric held by the first transfer arm 222, so that the rolled mask fabric forms the corresponding first mask fabric, so that the first cutting section 211 can move automatically in the left-right direction under the action of the second linear motion module 212. Optionally, the second linear motion module 212 is a synchronous belt linear motion module.

[0034] Please refer to the attached document. Figures 1-3 In this embodiment, the first cutting part 211 moves back and forth under the drive of the second linear moving module 212, and cuts the rolled mask fabric once during each movement, realizing a highly efficient operation mode of single movement and single cutting, avoiding the need to reset before cutting again, and improving cutting efficiency.

[0035] Please refer to the attached document. Figures 1-2 In this embodiment of the application, the first conveying component 31 includes two sets of fabric clamping modules 311. The two sets of fabric clamping modules 311 are arranged opposite each other in the left-right direction so as to form a conveying channel in the middle for the first mask fabric to pass through. The two sets of fabric clamping modules 311 jointly clamp the first mask fabric output by the first cutting component 20, so that the first mask fabric is stretched and flattened in the clamped state, preventing wrinkles from being generated in the subsequent hot pressing and stacking processes.

[0036] Each fabric clamping module 311 includes a first movable seat, a first adjusting seat, and multiple first fabric clamping members; the first adjusting seat is adjustablely connected to the first frame 10 and can be adjusted in the left-right direction; the first movable seat is movably connected to the first adjusting seat and moves in the front-back direction; the multiple first fabric clamping members are arranged along the length direction of the first movable seat and move with the movement of the first movable seat; in the two fabric clamping modules 311, the two opposing first fabric clamping members are used to clamp the two ends of the first mask fabric.

[0037] At this time, when the first adjusting seat is adjusted in the left and right direction relative to the first frame 10, the relative distance between the two first fabric clamping parts in the two sets of fabric clamping modules 311 can be adjusted; by the first adjusting seat driving the relative distance between the two first fabric clamping parts in the two sets of fabric clamping modules 311 to adjust, it can adapt to first mask fabrics of different width specifications, avoid the limitation of only being applicable to a single size of first mask fabric, and improve the versatility and adaptability of the fabric clamping module 311.

[0038] Please refer to the attached document. Figures 1-2 In this embodiment, the first conveying component 31 further includes a power device 312. The power device 312 is located on the outside of the first movable seat and drives the first movable seat to move back and forth in the front-back direction, so that the first mask fabric held by the first fabric clamping member passes through the hot pressing module 32, the meltblown fabric module 33, the lifting module 43, the welding module 50 and the finished product cutting module 60 in sequence, so that the first movable seat can achieve automated reciprocating movement under the action of the power device 312.

[0039] The power unit 312 includes a second connecting seat, a first motor, a first synchronous belt drive module, and a connecting block. The second connecting seat is connected to the first frame 10 so that the entire power unit 312 can be connected to the first frame 10 through the second connecting seat. The first motor is arranged vertically, and the connecting end of the first motor is connected to the second connecting seat. The first synchronous belt drive module is arranged in the front-back direction, and one end of the first synchronous belt drive module is connected to the output end of the first motor. The synchronous belt of the first synchronous belt drive module is connected to the first movable seat through the connecting block. The first movable seat moves back and forth in the front-back direction as the synchronous belt of the first synchronous belt drive module and the connecting block move, so as to achieve the movement effect of the first movable seat.

[0040] Please refer to the attached document. Figures 1-2 In this embodiment, each first fabric clamping component includes a first cylinder, a first clamping arm, and a second clamping arm. The first cylinder has a swingable first output end and a second output end, both of which swing in the up-down direction and can move closer to each other or further away from each other. The first clamping arm is connected to the first output end of the first cylinder, and the second clamping arm is connected to the second output end of the first cylinder. The first and second clamping arms move closer together under the drive of the first cylinder and can clamp the first mask fabric. The first mask fabric is clamped by each of the first fabric clamping components in sequence. By using the first cylinder to drive the first and second clamping arms to swing, the clamping and releasing actions can be switched quickly, improving the clamping efficiency of the first fabric clamping components.

[0041] Both the first and second clamping arms are long plates, and are arranged along the front-to-back direction, so that the clamping force is evenly distributed along a straight line, reducing the pressure per unit area, ensuring that the first mask fabric is not damaged, providing sufficient total friction, and achieving a stable grip.

[0042] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the lifting module 43 includes a first connecting seat and a first lifting plate; the first connecting seat is connected to the first frame 10, and the first lifting plate is vertically connected to the first connecting seat. During the lifting process, the third fabric output by the second conveying component 42 is superimposed on the second mask fabric in the upward direction to form the fourth fabric. The first lifting plate is lifted and lowered relative to the first connecting seat by a second cylinder, a servo electric cylinder or a cam lifting mechanism.

[0043] During the upward movement, the first lifting plate carries the third fabric through the gap of the first conveying component 31 and directly reaches the bottom of the second mask fabric. Then it continues to rise, pushing the third fabric upward so that it fits tightly and overlaps with the bottom surface of the second mask fabric, thereby completing the vertical composite of multiple layers of fabric to form the fourth fabric. After the overlap is completed, the first lifting plate descends and resets, ready to receive the next piece of the third fabric.

[0044] Please refer to the attached document. Figures 1-5 In this embodiment, the second conveying assembly 42 includes a first conveying roller module 421, a punching module 422, a rolling cutting module 423, a vacuum conveying module 424, a positioning module 425, and a second transfer module 426. The first conveying roller module 421 is disposed on the right side of the second frame 41 and connected to the second frame 41. The first conveying roller module 421 is used to convey rolls of mask fabric. The punching module 422, the rolling cutting module 423, the vacuum conveying module 424, the positioning module 425, and the second transfer module 426 sequentially convey the mask fabric through the first conveying roller module 421. The mask fabric conveyed by the roller module 421 is punched, cut, conveyed, positioned, and transferred to form a third fabric. Through the coordinated operation of the first conveying roller module 421, the punching module 422, the cutting module 423, the vacuum conveying module 424, the positioning module 425, and the second transfer module 426, an automated production line is formed. This line can automatically unwind and punch the roll of mask fabric, and automatically cut the continuous roll of fabric into sheet-like third fabric, and complete the subsequent positioning and transfer. This reduces labor costs and improves the production efficiency of the second conveying component 42.

[0045] The third fabric has a positioning notch, which is used for positioning by the positioning module 425. After positioning, the third fabric is conveyed to the lifting module 43 by the second transfer module 426. When the positioning module 425 is inserted into the positioning notch, it can restrict the degree of freedom of the third fabric on the horizontal plane, prevent the third fabric from shifting or rotating in subsequent processes, and ensure that the positioning position of each piece of the third fabric is consistent.

[0046] The punching module 422 includes a third connecting seat, a punching plate and a booster cylinder. The third connecting seat is connected to the second frame 41 and serves as the mounting base for the punching module 422. The punching module 422 is fixedly connected to the upper part of the second frame 41 through the third connecting seat.

[0047] The booster cylinder is located on the upper side of the third connecting seat. The booster cylinder is arranged vertically and serves as a power source to provide downward punching pressure. The fixed end of the booster cylinder is connected to the third connecting seat, and the output end of the booster cylinder is connected to the punching plate, which drives the punching plate to move in the up and down direction. During the downward movement of the punching plate, the punching plate punches the mask fabric downward, so that the roll of mask fabric can be automatically punched when different positions pass through the punching plate in sequence.

[0048] The rolling cutting module 423 also includes a fourth connecting seat, which is connected to the second frame 41. The first rolling cutting roller and the second rolling cutting roller are both connected to the fourth connecting seat. The first rolling cutting roller and the second rolling cutting roller are arranged in the vertical direction, with the first rolling cutting roller located below and the second rolling cutting roller located above. A cutting gap is formed between the first rolling cutting roller and the second rolling cutting roller for the mask fabric to pass through. The first rolling cutting roller and the second rolling cutting roller have a second cutting section and a third cutting section.

[0049] The second cutting section consists of an annular blade on one of the cutting rollers and an annular groove on the other cutting roller that corresponds to the blade. The function of the second cutting section is to perform transverse cutting along the width of the mask fabric, cutting the continuous, rolled, perforated fabric to form a third fabric. Simultaneously, the third cutting section consists of a raised forming blade on one of the cutting rollers, the shape of which matches a positioning notch, and a corresponding clearance groove on the other cutting roller. The third cutting section is located beside the second cutting section.

[0050] The second cutting section is used to cut the mask fabric to form the third fabric; the third cutting section is used to cut the third fabric to form a positioning notch. When the punched roll of mask fabric is conveyed between the first and second rollers, the first and second rollers rotate synchronously in opposite directions. The mask fabric moves forward under the action of friction. During the rotation, the second cutting section cuts into the mask fabric and cuts it laterally to form the third fabric; the third cutting section located at the edge punches the edge of the third fabric to form a positioning notch, and the first mask fabric with the positioning notch on the edge is output into the vacuum conveying module 424.

[0051] The third cutting section is V-shaped, and the positioning notch is also V-shaped, so that the positioning notch punched by the third cutting section on the third fabric is V-shaped. The positioning notch is set on the front edge of the third fabric, so that when the third fabric is conveyed to the positioning module 425, the positioning plate of the positioning module 425 can contact and insert into the positioning notch first, and perform positioning as the third fabric continues to be conveyed forward.

[0052] The first and second cutting rollers are respectively connected to a first gear and a second gear. The second gear meshes with the first gear. The cutting module 423 also includes a second motor and a second synchronous belt drive module. The connection end of the second motor is connected to the second frame 41. The two ends of the second synchronous belt drive module are respectively connected to the output end of the second motor and the first cutting roller, so that the power output by the second motor can be transmitted to the first cutting roller through the second synchronous belt drive module, thereby facilitating the automatic rotation of the first cutting roller. The second cutting roller rotates in the opposite direction as the first cutting roller rotates.

[0053] The vacuum conveying module 424 includes a fifth connecting seat and a vacuum conveyor belt; the fifth connecting seat is connected to the second frame 41 so that the vacuum conveying module 424 can be connected to the second frame 41 through the fifth connecting seat.

[0054] The vacuum conveyor belt is rotatably connected to the fifth connecting seat and rotates in a circular cycle. Specifically, the fifth connecting seat has a driving roller and a driven roller at its two ends, and the vacuum conveyor belt wraps around the driving roller and the driven roller. The driving roller is connected to a third motor. When the third motor is driven, the vacuum conveyor belt can rotate in a circular cycle around the driving roller and the driven roller.

[0055] The vacuum conveyor belt is equipped with multiple vacuum negative pressure holes. Under the action of negative pressure, each vacuum negative pressure hole adsorbs the third fabric, so that the third fabric can be tightly attached to the vacuum conveyor belt, preventing the third fabric from slipping, floating or wrinkling due to inertia during the conveying process. The vacuum conveyor belt transports the adsorbed and fixed third fabric to the positioning module 425 as it rotates.

[0056] The second transfer module 426 is equipped with a transfer head, which is located on one side of the positioning plate of the positioning module 425. This avoids the transfer head interfering with the lifting and lowering action of the positioning plate of the positioning module 425. After the positioning plate of the positioning module 425 positions the third fabric, the positioning plate of the positioning module 425 descends downwards, the transfer head clamps the positioned third fabric, and drives the third fabric forward, ensuring that the third fabric can be transported by the transfer head after positioning.

[0057] The positioning module 425 also includes a third cylinder and a positioning plate. The connecting end of the third cylinder is connected to the second frame 41, and the output end of the third cylinder is connected to the positioning plate. The third cylinder is arranged in the vertical direction. The positioning plate moves up and down in the vertical direction under the drive of the third cylinder. When the positioning plate rises to the first position, the positioning plate is directly opposite the positioning notch of the third fabric. By using the cooperation between the outer wall of the positioning plate and the inner wall of the positioning notch, the third fabric is precisely limited and corrected in the horizontal direction. When the positioning plate descends to the second position, it is lower than the third fabric, so that the positioning plate can detach from the third fabric and avoid the space above the third fabric. The transfer head drives the third fabric forward, avoiding interference between the transfer head and the positioning plate and ensuring the smooth transfer of the third fabric.

[0058] The second transfer module 426 includes a sixth connecting seat and a second movable seat. The sixth connecting seat is connected to the second frame 41 so that the second transfer module 426 can be connected to the second frame 41 through the sixth connecting seat. The second movable seat is movably connected to the sixth connecting seat and moves in the front-back direction so as to adjust the front-back position of the second movable seat relative to the sixth connecting seat. The second movable seat supports the transfer head and drives the transfer head to move in the front-back direction. Specifically, the second movable seat is connected to the sixth connecting seat through a guide rail. The second movable seat moves back and forth on the sixth connecting seat in the front-back direction under the drive of the fourth motor and the lead screw module so as to realize the automated movement of the transfer head.

[0059] The second fabric device 40 also includes a waste stripping roller module 44, which is connected to the second frame 41. The waste stripping roller module 44 is used to strip the film from the roll of mask fabric output by the first conveying roller module 421.

Figures 1-3 In this embodiment, the hot pressing module 32 is used to hot press the mask fabric conveyed by the first conveying component 31, so that the first mask fabric is hot-pressed and formed. The hot pressing module 32 includes an upper hot pressing mold and a lower hot pressing mold. The upper hot pressing mold is connected to a cylinder and has a built-in heating tube and temperature sensor. The lower hot pressing mold is fixed on the first frame 10. The lower hot pressing mold has a built-in heating element. The surface of the lower hot pressing mold is engraved with a curved groove that matches the outer surface of the cup-shaped mask. When the first conveying component 31 conveys the first mask fabric to the area directly below the hot pressing module 32, the upper hot pressing mold is lowered by the cylinder and closes with the lower hot pressing mold. Under the action of high temperature and pressure, the first mask fabric undergoes plastic deformation and is pressed into a semi-finished product with a cup-shaped three-dimensional curved surface contour.

[0061] The meltblown fabric module 33 is used to apply meltblown fabric to the first mask fabric that has been hot-pressed by the hot-pressing module 32. The meltblown fabric and the first mask fabric are stacked and conveyed forward under the drive of the first conveying component 31. At this time, the meltblown fabric module 33 is located in front of the hot-pressing module 32. The meltblown fabric module 33 includes a meltblown fabric unwinding mechanism, a guide roller group, and a flexible pressing mechanism. When the hot-pressed first mask fabric is moved forward by the first conveying component 31 to the meltblown fabric module 33, the meltblown fabric module 33 simultaneously outputs the cut or pre-formed meltblown fabric. The meltblown fabric is directly covered on the corresponding layer of the hot-pressed first mask fabric. The two are stacked one on top of the other to form the second mask fabric.
