[0027] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0028] Please see Figures 1 to 7 The preferred embodiment of this utility model is a mask folding and forming pressing device, which includes a frame 16, an upper pressing belt driven wheel 1, a lower pressing belt driven wheel 2, a belt guide wheel group 1 3, a belt guide wheel group 2 4, an upper pressing belt driving wheel 13, a lower pressing belt driving wheel 12, a belt pulley group motor 11, an upper pressing belt 14, a lower pressing belt 15, an upper pressing elastic movable wheel group 1 5, a lower pressing idler wheel group 6, an upper pressing elastic movable wheel group 2 7, and a lower pressing follower wheel group 8.

[0029] The frame 16 includes a lower horizontal section, an inclined section and an upper horizontal section connected in sequence.

[0030] The driven pulley 1 of the upper pressure belt and the driven pulley 2 of the lower pressure belt are arranged one above the other at the inlet end of the lower horizontal part of the frame 16; the belt guide pulley group 1 3 is arranged at the connection between the lower horizontal part and the inclined part of the frame 16, and the belt guide pulley group 2 4 is arranged at the connection between the inclined part and the upper horizontal part of the frame 16; the belt guide pulley group 1 3 and the belt guide pulley group 2 4 are used to adjust the transmission direction of the upper pressure belt 14 and the lower pressure belt 15.

[0031] The upper pressure belt drive pulley 13 and the lower pressure belt drive pulley 12 are mounted on the upper horizontal part of the frame 16, and gears are respectively provided at the ends of the upper pressure belt drive pulley 13 and the lower pressure belt drive pulley 12. The end gear 131 of the upper pressure belt drive pulley 13 and the end gear 121 of the lower pressure belt drive pulley 12 mesh with each other; the pulley group motor 11 is connected to the upper pressure belt drive pulley 13.

[0032] The upper pressure belt 14 is disposed between the upper pressure belt drive pulley 13 and the upper pressure belt driven pulley 1, and passes through the belt guide pulley group 3 and the belt guide pulley group 4; the lower pressure belt 15 is disposed between the lower pressure belt drive pulley 12 and the lower pressure belt driven pulley 2, and passes through the belt guide pulley group 3 and the belt guide pulley group 4.

[0033] The pulley motor 11 drives the upper pressure belt drive pulley 13 to rotate, providing power for the transmission of the upper pressure belt 14. When the upper pressure belt drive pulley 13 rotates, the end gear 131 of the upper pressure belt drive pulley 13 and the end gear 121 of the lower pressure belt drive pulley 12 mesh with each other, driving the lower pressure belt drive pulley 12 to rotate in the opposite direction, providing power for the transmission of the lower pressure belt 15. In this way, the pulley motor 11 can drive the upper pressure belt 14 and the lower pressure belt 15 to transmit power simultaneously.

[0034] The upper pressure elastic movable wheel group 5 and the lower pressure idler wheel group 6 are arranged one above the other on the inclined part of the frame 16, and are located in the upper pressure belt 14 and the lower pressure belt 15 respectively. A sprocket group 9 is installed on one side of the upper pressure elastic movable wheel group 5. The sprockets of the sprocket group 9 are connected in series by a chain, and the sprocket group 9 is driven to rotate by the sprocket group motor 10. Specifically, the sprocket group motor 10 is mounted on the inclined part of the frame 16 through a motor mounting base, and the output end of the sprocket group motor 10 is connected to one of the sprockets in the sprocket group 9 through a chain. When the sprocket group motor 10 rotates, it drives each sprocket in the sprocket group 9 to rotate. The upper pressure elastic movable wheel group 5 includes a number of pressure rollers arranged sequentially along the mask moving direction. Each pressure roller is mounted on a pressure roller bearing seat. Each pressure roller bearing seat has guide grooves on both sides, and a pressure spring is installed at the upper end of each pressure roller bearing seat. When the mask is transported by the upper pressure belt 14 and the lower pressure belt 15 to the upper pressure elastic movable wheel group 5 and the lower pressure idler wheel group 6, the lower pressure idler wheel group 6 only rotates in response. The pressure roller of the upper pressure elastic movable wheel group 5 is affected by the thickness of the mask and is pushed up along the guide groove to the side where the spring is installed. The mask is therefore subjected to the pressure of the upper pressure elastic movable wheel group 5 and passes through each pressure roller in turn, pressing the folded mask into shape.

[0035] The upper pressure elastic movable wheel set 7 and the lower pressure follower wheel set 8 are located on the upper horizontal part of the frame 16, one above the other, and are located at the output ends of the upper pressure belt 14 and the lower pressure belt 15 respectively. The upper pressure elastic movable wheel set 7 and the lower pressure follower wheel set 8 are driven by gears. Specifically, a transmission gear set 17 is provided on one side of the upper pressure elastic movable wheel set 7 and the lower pressure follower wheel set 8. The adjacent gears of the transmission gear set 17 mesh with each other. One of the gears of the transmission gear set 17 is connected to the end gear 121 of the lower pressure belt drive pulley 12 by a belt. When the lower pressure belt drive pulley 12 rotates, it provides power to the transmission gear set 17, thereby driving the upper pressure elastic movable wheel set 7 and the lower pressure follower wheel set 8 to rotate. The pressure rollers of the upper pressure elastic movable roller group 7 and the lower pressure follower roller group 8 will simultaneously apply pressure to the mask. However, among the upper pressure elastic movable roller group 5 and the lower pressure idler roller group 6, only the pressure roller of the upper pressure elastic movable roller group 5 applies pressure to the mask, while the lower pressure idler roller group 6 only generates follower rotation.

[0036] The structure of the upper pressure elastic movable wheel group 2 7 is the same as that of the upper pressure elastic movable wheel group 1 5. It also includes several pressure rollers arranged sequentially along the direction of mask movement. Each pressure roller is mounted on a pressure roller bearing seat. Guide grooves are provided on both sides of each pressure roller bearing seat, and a pressure spring is installed at the upper end of each pressure roller bearing seat. When the mask is transported between the upper pressure elastic movable wheel group 2 7 and the lower pressure follower wheel group 8 by the upper pressure belt 14 and the lower pressure belt 15, the pressure rollers of the upper pressure elastic movable wheel group 2 7 are pushed up along the guide grooves on the side where the pressure springs are installed due to the thickness of the mask. The mask is thus subjected to the pressure of the upper pressure elastic movable wheel group 2 7. As it passes through each pressure roller in sequence, the folded mask is further compressed and shaped.

[0037] The mask folding and forming pressing device of this utility model is located between the folding machine and the mask filling machine. In use, the mask cloth folded by the folding machine is conveyed by the folding machine to the positions of the upper pressure belt driven pulley 1 and the lower pressure belt driven pulley 2 and then into the upper pressure belt 14 and the lower pressure belt 15. The belt pulley group motor 11 provides power for the transmission of the upper pressure belt 14 and the lower pressure belt 15. The belt guide pulley group 1 3 and the belt guide pulley group 2 4 can adjust the transmission direction of the upper pressure belt 14 and the lower pressure belt 15. After the face mask enters the upper pressure belt 14 and the lower pressure belt 15, it is transported to the lower pressure idler wheel group 6 and the upper pressure elastic movable wheel group 5. When the sprocket group motor 10 rotates, it drives each sprocket in the sprocket group 9 to rotate, which in turn drives each pressure wheel in the upper pressure elastic movable wheel group 5 to rotate. When the face mask is transported to the upper pressure elastic movable wheel group 5 and the lower pressure idler wheel group 5 by the upper pressure belt 14 and the lower pressure belt 15, the lower pressure idler wheel group 5 only rotates in a follow-up manner. The pressure wheel of the upper pressure elastic movable wheel group 5 is affected by the thickness of the face mask and is pushed up along the guide groove to the side where the spring is installed. The face mask is therefore subjected to the pressure of the upper pressure elastic movable wheel group 5. It passes through each pressure wheel in turn, and the folded face mask is compacted and shaped. The rolled face mask is transported out through the upper pressure belt drive wheel 13 and the lower pressure belt drive wheel 12. After being rolled by the upper pressure elastic movable wheel group 2 7 and the lower pressure follower wheel group 8, it is transported to the feeding station of the face mask filling machine.

[0038] In summary, the mask folding and forming pressing device of this utility model is located between the folding machine and the mask filling machine. It can further shape and roll the folded mask. The rolled mask will not spring back and will be conveyed from the outlet position to the feeding station of the mask filling machine.

Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
