Description

Technical Field

[0002] Masks are a type of sanitary product, generally worn on the nose and mouth to filter the air entering the nose and mouth, so as to prevent harmful gases, odors, and droplets from entering and exiting the wearer's nose and mouth. Masks on the market have a certain filtering effect on the air entering the lungs. Wearing a mask is very effective when respiratory infectious diseases are prevalent or when working in an environment with pollutants such as dust.

[0040] See also Figure 2 , Figure 8 and Fig. 9As shown, in this embodiment, the packaging station 4 includes a shell 48, and the shell 48 is provided with a feeding component 49 for supplying mask packaging film and a conveyor belt 50 for conveying masks and mask packaging film. The conveyor belt 50 is provided with an edge trimming component 51 for trimming and forming the mask packaging film from the inlet to the outlet, a middle sealing hot melt component 52 for hot-melt edge sealing of the mask packaging film, a pressing component 53 for pressing the edge of the mask packaging film after edge sealing, and an end sealing component 54 for fusing and independently packaging the mask packaging film. The conveyor belt 50 is provided with an induction sensor 55 for detecting whether there is a mask at the feeding port of the conveyor belt 50; the shell 48 is also provided with an ambient temperature sensor, a hot melt temperature sensor and a central control panel 67, the ambient temperature sensor is arranged outside the shell 48, and the hot melt temperature sensor is respectively arranged on the middle seal hot melt component 52 and the end seal fuse component 54; the conveyor belt 50, the middle seal hot melt component 52, the end seal fuse component 54, the induction sensor 55, the ambient temperature sensor and the hot melt temperature sensor are all electrically connected to the central control panel 67.

[0041] During actual use, the mask packaging film roll is placed on the feeding component 49, the mask packaging film is stretched out and passes through the feeding port of the conveyor belt 50, the edge trimming component 51, the middle sealing hot melt component 52, the edge pressing component 53 and the end sealing fuse component 54 in sequence.

[0042] Specifically, first, when the mask with the ear strap line processed is sent to the feeding port of the conveyor belt 50 through the second transfer belt 6 and is located above the mask packaging film, the induction sensor 55 senses the mask and outputs a trigger signal to the central control panel 67. The central control panel 67 controls the conveyor belt 50 to start driving according to the trigger signal. The conveyor belt 50 drives the mask and the mask packaging film to move from the feeding port of the conveyor belt 50. When the mask and the mask packaging film are moved to the edge trimming component 51, the two side edges of the mask packaging film are wrapped around the mask towards each other through the edge trimming component 51, and the edges of the two side edges are pressed by the edge trimming component 51 to form the initial edge sealing.

[0043] Next, when the mask covered by the mask packaging film is moved to the middle sealing hot melt assembly 52, the middle sealing hot melt assembly 52 performs hot melting and fixing of the sealing edge to prevent the two sides of the mask packaging film from being separated, thereby forming a packaging heat seal for the mask.

[0044] Next, when the mask after the first step of packaging and heat sealing moves to the edge pressing assembly 53, the edge pressing assembly 53 performs a pressure operation on the edge sealing to form a secondary edge sealing, further ensuring the stability of the packaging.

[0045] Next, when the packaged mask is moved to the end seal fuse assembly 54, the mask packaging films at both ends of the mask are packaged and melted by the end seal fuse assembly 54, thereby forming an independent packaging effect for the mask.

[0046] In the above process, the ambient temperature sensor is used to detect the air temperature of the working environment, and the hot melt temperature sensor is used to detect the working temperature of the middle seal hot melt component 52 and the working temperature of the end seal fuse component 54, and the air temperature value of the working environment, the working temperature value of the middle seal hot melt component 52 and the working temperature value of the end seal fuse component 54 are displayed through the central control panel 67. When the staff finds that the air temperature value of the working environment is too different from the working temperature value, the staff can adjust the working temperature of the middle seal hot melt component 52 and / or the working temperature of the end seal fuse component 54 through the central control panel 67 to ensure the packaging heat sealing effect and the fusing independent packaging effect.

[0047] Specifically, the central control panel 67 may be an existing PLC, a computer or an embedded processing controller.

[0048] The inductive sensor 55 may be an infrared inductive sensor 55. The mask of the conveyor belt can be detected by infrared rays, thereby triggering the driving of the conveyor belt 50, thereby improving the degree of automation and the accuracy of detection.

[0049] See also Figure 2 , Figure 8 and Fig. 9 As shown, in this embodiment, the packaging station 4 further includes a feeding belt 65 for conveying the masks output from the second conveying belt 6 to the feeding port of the conveying belt 50. The degree of automation is improved.

[0051] In actual use, the two sides of the mask packaging film move between the first hot melt sheet 56 and the second hot melt sheet 57, and the first driving member 59 drives the second hot melt sheet 57 to move to abut against the first hot melt sheet 56, thereby performing the function of heat-sealing the two sides of the mask packaging film. Specifically, a return spring is provided between the first hot melt sheet 56 and the second hot melt sheet 57, one end of the return spring is connected to the first hot melt sheet 56, and the other end of the return spring is connected to the second hot melt sheet 57.
