Description

Technical Field

[0001] The present application relates to the field of mask production and processing equipment, and in particular to an ear strap conveying device for a fully automatic mask machine. Background Art

[0002] At present, masks are more important personal protective equipment for people's daily travel. The existing mask production process mainly includes the production of the mask body and the welding of ear straps. The production of the mask body mainly uses meltblown non-woven fabrics to cut as the protective part of the mask. Meltblown non-woven fabrics are mainly made of polypropylene as the main raw material. The fiber diameter is very small, there are many gaps between the fibers, the structure is fluffy, and the wrinkle resistance is good. The ultrafine structure of the ultrafine fiber with a unique capillary structure increases the number and surface area of ​​fibers per unit area, so that the mask has good filtering and shielding properties. The welding of the ear straps is to weld the ear straps to the two ends of the mask body through a welder.

[0003] In the related art, a Chinese patent application numbered CN202120371934.1 proposes an ear strap spot welding device for a mask machine, which relates to the field of mask production and processing equipment. The device comprises an output rack, a lifting rod, and a lifting plate arranged at the output end of the lifting rod. A conveyor chain is provided at one end of the output rack, and a plurality of mask body positioning boxes for conveying masks are fixed to the conveyor chain. The device is characterized in that the output rack comprises a top plate and two bottom plates, the two bottom plates are parallel to each other, the top plate is detachably arranged at the upper ends of the two bottom plates, a lifting cylinder is fixed at one end of the top plate away from the bottom plate, the output end of the lifting cylinder is fixedly connected to the lifting rod, a transfer conveyor belt is rotatably arranged between the two bottom plates, and a placement plate is respectively lifted and lowered at the opposite ends of the two bottom plates, and an abutment block is fixed at one end of the placement plate. In the above technical solution, while transmitting the masks, the deviation generated during the placement of multiple masks is reduced, which facilitates the packaging of the masks and increases work efficiency.

[0004] Regarding the above-mentioned related technologies, the storage box is placed directly on the conveyor belt, and the lifting plate squeezes the mask into the storage box. Since there is no mechanism on the conveyor belt to fix the storage box, the storage box is very likely to shift in position. At this time, the mask cannot fall directly into the mask, affecting the normal mask transportation work. Utility Model Content

[0018] The following is combined with Figure 1 This application is described in further detail.

[0019] The embodiment of the present application discloses an ear strap conveying device for a fully automatic mask machine. Figure 1 An ear band conveying device of a fully automatic mask machine includes an output rack 1 and a lifting plate 2 lifted and lowered on the output rack 1. In this embodiment, the lifting drive can be a reciprocating mechanism. The output rack 1 is provided with a conveyor rack 3 below the lifting plate 2. The conveyor rack 3 is connected to a conveyor belt 4. The conveyor belt 4 is also driven by a motor and two conveyor rollers. A plurality of placement boxes 5 are placed on the conveyor belt 4. The placement box 5 is located directly below the lifting plate 2. When the lifting plate 2 pushes the mask out of the output rack 1, the mask falls onto the placement box 5.

[0020] In order to achieve the effect of fixing the placement box 5, the conveying frame 3 is slidably connected with a bracket 6 on both sides of the placement box 5, and the bracket 6 is slidingly provided with a slide rod 7. The slide rod 7 is fixedly connected to one end of the slide rod 7 close to the placement box 5, and the splint 8 is used to clamp the two side walls of the placement box 5. A reset component is provided between the slide rod 7 and the bracket 6. The reset component includes a handle 9 and an elastic member. The handle 9 is fixedly connected to the end of the slide rod 7 away from the splint 8. The length direction of the handle 9 is set perpendicular to the length direction of the slide rod 7. The elastic member is used to realize the reset of the slide rod 7. The reset member is set as a spring 10. The two ends of the spring 10 are respectively fixedly connected to the handle 9 and the side wall of the bracket 6.

[0021] The conveyor frame 3 is provided with a driving mechanism for driving the two splints 8 away from each other. The driving mechanism includes two L-shaped driving blocks 11 and a power assembly for separating the two driving blocks 11. The driving block 11 is fixedly connected to the handle 9. The power assembly includes a triangular block 12 and a reciprocating member for realizing the reciprocating motion of the triangular block 12. The triangular block 12 is slidably connected to the conveyor frame 3. The vertical section of the driving block 11 is fixedly connected to the handle 9. The horizontal sections of the two driving blocks 11 are respectively in contact with the two side surfaces of the triangular block 12. The triangular block 12 moves in the vertical direction. The reciprocating member is set as a cylinder 13. The cylinder 13 is fixedly connected to the conveyor frame 3. The output of the cylinder 13 The ends are fixedly connected to the side walls of the triangular block 12, and the connection position between the cylinder 13 and the triangular block 12 is not the two side edges where the two driving blocks 11 and the triangular block 12 abut; when the cylinder 13 drives the triangular block 12 to move upward, the triangular block 12 moves the two driving blocks 11 in the direction away from each other, and at this time the splint 8 and the slide bar 7 both move in the direction away from the placement box 5. When the placement box 5 is moved to the position between the two splints 8, the cylinder 13 drives the triangular block 12 to move downward, and under the elastic force of the spring 10 to restore its original shape, the two splints 8 both move toward the placement box 5, achieving the effect of the two splints 8 clamping the placement box 5.

[0022] The side wall where the clamping plate 8 abuts the placement box 5 is fixedly connected with a rubber pad, and the rubber pad is bonded to the clamping plate 8 by a glue layer. The rubber pad is used to reduce the squeezing impact force of the clamping plate 8 on the placement box 5 to ensure the stability of the placement box 5.

[0023] The implementation principle of the ear band conveying device of a fully automatic mask machine in an embodiment of the present application is as follows: when the cylinder 13 drives the triangular block 12 to move upward, the triangular block 12 moves the two driving blocks 11 in a direction away from each other, and at this time the splint 8 and the slide bar 7 both move in a direction away from the placement box 5. When the placement box 5 is moved to a position between the two splints 8, the cylinder 13 drives the triangular block 12 to move downward. Under the elastic force of the spring 10 to restore its original shape, the two splints 8 both move toward the placement box 5, and the rubber pad is squeezed and deformed, thereby achieving the effect of clamping and fixing the placement box 5.
