However, traditional mask production lines are mostly for flat masks, and the overall production capacity of cup-shaped masks is much lower.

[0013] The working principle of an automated cup-shaped mask cutting, sealing, and collection machine: Step 1: The worktable rotates, and one of the workstation fixtures moves to the feeding device. The suction cup of the feeding device picks up the mask fabric and then moves the mask fabric onto the workpiece fixture. Step 2: The worktable rotates again, moving the workstation fixture from Step 1 under the cutting device. The pressing cylinder A presses down, and the cutting mold applies pressure to the mask fabric to achieve initial cutting. Then, the pressing cylinder A resets. Step 3: The workbench rotates again, moving the workstation fixture from Step 1 to the edge sealing device. The edge sealing device's pressing cylinder B is guided by the slide rail slider, driving the ultrasonic welding head to press down vertically. The ultrasonic welding head vibrates to weld the edge of the mask fabric, and then the pressing cylinder B resets. Step 4: Due to the welding process, the mask will not easily detach from the cup-shaped mold. The finished mask moves away from the sealing device and enters the collection device via the rotating worktable. The cup-shaped mold of the station fixture, which is fixed on the turntable, rotates 180°. During the rotation of the cup-shaped mold, the arc-shaped slider at the outer end of the push rod gradually contacts and squeezes the trapezoidal block. The arc-shaped slider gradually presses down on the push rod. At this time, the push plate at the inner end of the push rod pushes the workpiece out of the mold and into the collection bucket. Then, the motor drives the cup-shaped mold to rotate again, the arc-shaped slider separates from the trapezoidal slider, and the push rod resets under the action of the spring. At this time, the cup-shaped mold enters the loading state, and one round of operation of this workpiece fixture is completed.

[0014] Step 5: There are a total of six workpiece positions on the worktable. Perform steps 1 to 4 above in sequence to automatically process and collect cup-shaped masks. When the collection bucket is almost full, the machine can be paused, the full collection bucket can be removed from the frame and replaced with an empty collection bucket.

[0015] Compared with the prior art, the present invention has the following advantages: it is reasonably designed and has feeding, cutting, sealing and collecting functions, which can realize the automated production of cup-shaped masks. The use of cam divider and turntable working structure effectively reduces the overall size and floor space of the machine. The feeding device, cutting device and sealing device are all pneumatically driven, clean and reliable. The collecting device adopts mechanical extrusion, which is simple in structure, low in cost and easy to maintain. Attached Figure Description

[0039] The working principle of an automated cup-shaped mask cutting, sealing, and collection machine: Step 1: The worktable rotates, and one of the workstation fixtures moves to the feeding device. The suction cup of the feeding device picks up the mask fabric and then moves the mask fabric onto the workpiece fixture. Step 2: The worktable rotates again, moving the workstation fixture from Step 1 under the cutting device. The pressing cylinder A presses down, and the cutting mold applies pressure to the mask fabric to achieve initial cutting. Then, the pressing cylinder A resets. Step 3: The workbench rotates again, moving the workstation fixture from Step 1 to the edge sealing device. The edge sealing device's pressing cylinder B is guided by the slide rail slider, driving the ultrasonic welding head to press down vertically. The ultrasonic welding head vibrates to weld the edge of the mask fabric, and then the pressing cylinder B resets. Step 4: Due to the welding process, the mask will not easily detach from the cup-shaped mold. The finished mask moves away from the sealing device and enters the collection device via the rotating worktable. The cup-shaped mold of the station fixture, which is fixed on the turntable, rotates 180°. During the rotation of the cup-shaped mold, the arc-shaped slider at the outer end of the push rod gradually contacts and squeezes the trapezoidal block. The arc-shaped slider gradually presses down on the push rod. At this time, the push plate at the inner end of the push rod pushes the workpiece out of the mold and into the collection bucket. Then, the motor drives the cup-shaped mold to rotate again, the arc-shaped slider separates from the trapezoidal slider, and the push rod resets under the action of the spring. At this time, the cup-shaped mold enters the loading state, and one round of operation of this workpiece fixture is completed.

[0040] Step 5: There are a total of six workpiece positions on the worktable. Perform steps 1 to 4 above in sequence to automatically process and collect cup-shaped masks. When the collection bucket is almost full, the machine can be paused, the full collection bucket can be removed from the frame and replaced with an empty collection bucket.

Of course, a fixed connection can also be replaced by an integral structure (e.g., manufactured by casting) (except where it is obviously impossible to use an integral molding process).
