As shown in Fig.2, the system for nose clip insertion in a face mask production includes a nose clip forming device 10 for forming nose clips from a raw material; a nose clip dispenser unit 20 for loading formed nose clips one above another in a vertical nose clip stack; a pushing device 30 for pushing out a bottom nose clip from the vertical nose clip stack; a coating device 40 for coating the bottom nose clip with wet adhesive; and a pressing device 50 for pressing the bottom nose clip coating with wet adhesive on to a face mask base.

Fig.3 shows a part of the system for nose clip insertion in a face mask production. Fig.4 is a structure diagram showing the nose clip dispenser unit. Fig.5A-5D are diagrams showing the pushing and coating process of the nose clip. Fig 6 is diagram showing the pressing process of the nose clip.

Now the specific embodiment of the present application is described with reference of Figs. 3-7.

In the present embodiment, as shown in Fig 3, the nose clip forming device 10 includes a forming machine 12 and a continuous roll 11 with multiple flaps or folds formed at a longitudinal center along its length on the forming machine 12. The forming machine 12 can be a commonly used forming machine in the plastic film/paper industry that can do seal & cut, bag making or other similar function with a cut-out section of the web as shown in Fig.3. One skilled in the art can find any forming machine 12 for implementing the present application.

Along the edge of the continuous roll 11, the nose clip dispenser unit 20 is fabricated in such a way that vertical stack of pre-cut nose clips are loaded in the dispenser as shown in Fig.3. As shown in Fig.4, the nose clip dispenser unit 20 includes two vertical walls 21 arranged in parallel for loading the nose clips one above another in a vertical nose clip stack 60 between the two vertical walls, such that forming a neatly arranged column of ready-to-dispense nose clips. As shown in Fig.5A-5B, the pushing device 30 is a horizontal bar arranged next to a bottom of one vertical wall 21 of the nose clip dispenser 20.

In a preferable embodiment of the present application, an interval is arranged between the lower end of the two vertical walls 21 of the nose clip dispenser 20 and the upper surface of the continuous roll 11 for transporting the nose clip. The horizontal bar can be arranged next to at least one of the two vertical walls 21, or along the transporting direction of the nose clip. In such a way, when the horizontal bar is moved towards to the nose clip dispenser, such as by a horizontal movement which is activated or transmitted by up-down and left-right movement of a machine stroke on the horizontal bar located when the horizontal bar is arranged next to the nose clip dispenser 20; or by a forward movement along the transporting direction of the nose clip when the horizontal bar is arranged on the continuous roll 11; the horizontal bar pushes bottom nose clip 61 from the vertical nose clip stack 60 through the interval 62 as shown in Fig.5A. Then the pushed out bottom nose clip 61 is then moved passed through a hanging curtain 41 coated with wet adhesive to allow it partially coated and finally fall by its gravitational force into the U-shape cavity 51 receiving the bottom nose clip 61 coated with wet adhesive. As shown in Fig.5A, the hanging curtain 41 is connected with a container 42 full with wet adhesive for supply the wet adhesive to the hanging curtain 41. One skilled in the art knows that, as the horizontal bar can be arranged at the left vertical wall 21, the right vertical wall 21, or along the transporting direction of the nose clip, the nose clip would be pushed out in different directions, and the location of the following structure of the system for nose clip insertion in a face mask production should be adjusted accordingly. Based on the teaching of the present application, one skilled in the art can make such modification and obtain different embodiments of system for nose clip insertion in a face mask production according to the present application.

As shown in Fig. 6, the partially adhesive coated nose clip stays well within the U-shape cavity 51 until it is being pressed on and securely trapped inside the folded edge by a pressing roller 52 on to a face mask base as shown in Fig.6. One skilled in the art should know that the face mask base can be any shape and any size and made any material.

Fig.5C has shown a different embodiment of the coating device 40, in which the hanging curtain 41 coated with wet adhesive can be replaced by a small adhesive roller 44 partially immersed in a small rectangle container 43. As the nose clip 61 passes over the slightly protruded free-turning roller 44, the nose clip 61 will be partially coated.

Fig.5D has shown a different embodiment of the coating device 40, in which a flexible rod 45 is hanged vertically in the air with its tip ends immersed in the liquid adhesive of a small rectangle container 43. One skilled in the art should know that the flexible rod 45 can be hanged vertically in different ways, such as fixed on a horizon arranged bar, plate and so on.

When the nose clip 61 hits the flexible rod 45, it will cause the flexible rod 45 to bend. The bending of the flexible rod 45 causes the liquid adhesive in the small rectangle container 43 coated the tip end to gradually rise upwards until the adhesive coated tip end touches the nose clip 61 and transferring some adhesive onto the nose clip 61. The nose clip 61 continued to be pushed by the horizontal bar until it drops into the U-shape cavity structure of the paper edge. In that way, the nose clip 61 will be coated with adhesive in a more reliable, simple and easy way in a real-life practical process. One skill in the art will know that putting more coated spots by having more flexible rods will provide more options for the amount of adhesive to be coated onto the nose clip in real-life application.

Optionally, a bottom plate can be arranged for supporting the nose clip dispenser unit 20, and such bottom plate can be tiled at an angle of 10degree to 80 degree to facilitate easier pushing of the pushing device to provide more option in real-life application based on the site set-up and conditions, etc.

In a typical downwards knife cutting bag making or pouching machine, the location and position of the system for nose clip insertion in the present application can be adjusted based on required length of the face mask to be cut so that it synchronizes the specific placement location of the nose clip to be inserted .

The method and system for nose clip insertion in a face mask production are practical, reliable, feasible, economical as well as simple and easy to implement with a low set up cost. The method and system for nose clip insertion in a face mask production can be quickly and easily implemented and simple to maintain with low cost without the use of expensive ultrasonic sealing equipment and cylindrical rotation die.

The foregoing is a further detailed description of the present application in connection with specific preferred embodiments, and cannot be considered as that the specific implementation of the present application is limited to these illustrations. It will be apparent to those skilled in the art that any various modifications or substitutions may be made to the present application without departing from the spirit of the invention, and such modifications or substitutions should be considered as falling within the scope of the present application.
