[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4 The utility model provides a technical solution: an automatic ear folding device for mask packaging, comprising two vertical plates 1, two pulleys 1 rotatably connected between the two vertical plates 1, and a conveyor belt 101 wound around the two pulleys 1; workers place masks on the surface of the conveyor belt 101, and the conveyor belt 101 is driven to be transported by the rotation of the pulley 1, thereby moving the masks on the surface of the conveyor belt 101.

[0028] The tops of the two vertical plates 1 are connected to a triangular plate 2; the masks are laid flat on the surface of the conveyor belt 101 one by one, and the ear straps on both sides of the mask hang down on the vertical plate 1. The mask is driven by the conveyor belt 101 to move, so that the ear straps move along the top inclined surface of the triangular plate 2 until the ear straps are in contact with the side walls of the triangular plate 2. Then, they hang down on the surface of the mask due to gravity, thereby completing the automatic retraction of the ear straps.

[0029] The tops of the two vertical plates 1 are commonly connected to a shelf 201, and a hot pressing plate 202 is slidably connected inside the shelf 201. The top of the hot pressing plate 202 is connected to a spring 205, and the other end of the spring 205 is connected to the inner wall of the shelf 201. The outer wall of the shelf 201 is provided with a driving member 1 for driving the hot pressing plate 202 to lift; the hot pressing plate 202 is lifted by the driving member 1 until the mask with the ear straps folded moves to the lower end of the hot pressing plate 202, and the driving member 1 is reset, so that the hot pressing plate 202 moves downward under the elastic action of the spring 205, so that the hot pressing plate 202 moves back and forth inside the shelf 201, thereby heat-pressing the mask, and then shaping the ear straps fitted to the surface of the mask, which is convenient for subsequent packaging.

[0030] An intermittently rotating driving member 2 is provided on the outside of any pulley 1. The driving member 2 drives the pulley 1 to rotate intermittently, so that the conveyor belt 101 drives the masks on its surface to move intermittently, and cooperates with the reciprocating movement of the hot pressing plate 202 to heat press each mask under the hot pressing plate 202, and the masks after heat pressing are conveyed through the conveyor belt 101.

[0031] The top of the hot press plate 202 is connected to a vertical rod 204, and the vertical rod 204 is slidably connected to the inside of the rack 201. The top of the vertical rod 204 is connected to a connecting plate 206, and the bottom end of the connecting plate 206 is attached to the top of the rack 201. When the hot press plate 202 moves, the vertical rod 204 is driven to slide inside the rack 201. Under the action of the connecting plate 206, the hot press plate 202 can be limited to prevent the hot press plate 202 from moving downward excessively and squeezing the conveyor belt 101.

[0032] Driving member 1 includes rotating rod 1 3, rotating rod 2 301, cam 302 and belt 303;

[0033] Any vertical plate 1 is rotatably connected to a rotating rod 1 3 inside, and any vertical plate 1 side wall is connected to a motor, and the output end of the motor is sleeved with the end of the rotating rod 1 3, and the side wall of the shelf 201 is rotatably connected to a rotating rod 2 301, and the outer wall of the rotating rod 2 301 is sleeved with a cam 302, and the outer walls of the rotating rod 1 3 and the rotating rod 2 301 are both sleeved with pulley 2, and the outer walls of the two pulleys 2 are both wrapped with belts 303. By starting the motor, the output end of the motor drives the rotating rod 1 3 and the pulley 2 on the rotating rod 1 3 to rotate. Under the transmission action of the belt 303, the other pulley 2 on the outer wall of the rotating rod 2 301 is rotated, thereby driving the rotating rod 2 301 to rotate on the outer wall of the shelf 201, so that the cam 302 rotates, and the raised end of the cam 302 lifts the connecting plate 206, so that the connecting plate 206 drives the hot pressing plate 202 connected to the vertical rod 204 to rise and fall, thereby hot pressing the mask.

[0034] A support plate 203 is commonly connected between the two vertical plates 1. The top of the support plate 203 is in contact with the inner wall of the conveyor belt 101. When the hot pressing plate 202 moves downward and squeezes the mask, the support plate 203 can lift the conveyor belt 101 under the hot pressing plate 202 to prevent the conveyor belt 101 from moving downward and causing deformation.

[0035] There are two T-shaped slots inside the rack 201, and T-shaped sliders adapted to the T-shaped slots are slidably connected inside the two T-shaped slots. The two T-shaped sliders are connected to the side walls of the hot press plate 202. The hot press plate 202 drives the T-shaped sliders to slide in the T-shaped slots during the lifting process, thereby improving the stability of the hot press plate 202 during the movement process and maintaining the balance of the hot press plate 202.

[0036] Driving member 2 includes gear 1 4, gear 2 401 and rotating rod 3 402;

[0037] The outer wall of the rotating rod 3 is sleeved with a gear 4, and the outer wall of the gear 4 is meshed with a gear 2 401. The inner wall of the gear 2 401 is connected to the rotating rod 3 402. The rotating rod 3 402 is rotatably connected to the inner wall of the vertical plate 1. The rotating rod 3 402 is sleeved with one end of any pulley. When the rotating rod 3 is driven by the motor to rotate, the gear 4 is driven to rotate synchronously. Through the meshing of the gear 14 and the gear 2 401, the gear 2 401 drives the rotating rod 3 402 to rotate on the vertical plate 1, and the rotating rod 3 402 drives a pulley 1 connected to it to rotate, thereby moving the conveyor belt 101, and then driving the other pulley 1 to rotate intermittently, so that the mask on the surface of the conveyor belt 101 can be intermittently moved.

[0038] The inner wall of the rack 201 is equidistantly connected to a plurality of rollers 5 for rotation. The masks after hot pressing will be at the lower end of the plurality of rollers 5. As the masks move on the surface of the conveyor belt 101, the rollers 5 can further squeeze the masks after hot pressing, thereby enhancing the hot pressing effect of the hot pressing plate 202.

[0039] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
