Abstract:
1. A face mask manufacturing machine comprising a mask fusion apparatus, the mask fusion apparatus comprising: a platform; a first-side edge fusion module arranged on the platform, comprising a frame, at least one first pneumatic cylinder, a first fusion die, a first ultrasonic heating device, and a first die cushion, the frame being arranged on and extending from a top surface of the platform, the first pneumatic cylinder being mounted to the frame and having a vertically movable linear shaft, the first fusion module being mounted to a lower end of the linear shaft to press onto a multilayer cloth to form a first-side edge contour of the mask, the first ultrasonic heating device being mounted to the frame and coupled to the first fusion die in order to induce ultrasonic vibration on and thus heating the first fusion die to increase temperature of the first fusion die for heat-fusion of the first-side edge contour of the multilayer cloth, the first die cushion being arranged in the platform in a vertically movable manner at a location below the first fusion die; a second-side edge fusion module arranged on the platform and adjacent to the first-side edge fusion module in a forward direction, comprising a frame, at least one second pneumatic cylinder, a second fusion die, a second ultrasonic heating device, and a second die cushion, the frame being arranged on and extending from the top surface of the platform, the second pneumatic cylinder being mounted to the frame and having a vertically movable linear shaft, the second fusion module being mounted to a lower end of the linear shaft to press onto the multilayer cloth to form a second-side edge contour of the mask, the second ultrasonic heating device being mounted to the frame and coupled to the second fusion die in order to induce ultrasonic vibration on and thus heating the second fusion die to increase temperature of the second fusion die for heat-fusion of the second-side edge contour of the multilayer cloth, the second die cushion being arranged in the platform in a vertically movable manner at a location below the second fusion die; a folding device arranged on the platform and adjacent to the second-side edge fusion module in the forward direction, comprising a guide board assembly and a guide roller set, the guide board assembly being arranged on the platform and comprising a guide board, which has a forward end portion forming a conic shape and an expanded rearward end portion opposing the second-side edge fusion module for guiding the multilayer cloth toward the forward end portion thereof for folding the multilayer cloth, the guide roller set being arranged on the top surface of the platform and adjacent to the forward end portion of the guide board, the guide roller set comprising two guide rollers that are horizontally adjacent to each other for driving the folded multilayer cloth through therebetween; and a center line fusion module arranged on the top surface of the platform and adjacent to the folding device, the center line fusion module comprising a frame, at least one third pneumatic cylinder, a third fusion die, a third ultrasonic heating device, and a third die cushion, the frame being arranged on and extending from the top surface of the platform, the third pneumatic cylinder being mounted to the frame and having a vertically movable linear shaft, the third fusion module being mounted to a lower end of the linear shaft to press onto the multilayer cloth to form a center line contour of the mask, the third ultrasonic heating device being mounted on the frame and coupled to the third fusion die in order to induce ultrasonic vibration on and thus heating the third fusion die to increase temperature of the third fusion die for heat-fusion of the center line contour of the multilayer cloth, the third die cushion being arranged in the platform in a vertically movable manner at a location below the third fusion die.
