Description

Technical Field

[0001] This application relates to the technical field of medical device production equipment, and particularly to a mask processing device. Background Art

[0002] Masks are medical supplies that are frequently used in people's daily lives and often need to be carried around. To ensure the portability and usability of such medical supplies, they are often packaged in a single-piece independent packaging method. At the same time, this packaging method also ensures that such medical supplies are cleaner and more hygienic during storage, transportation, and carrying. On the other hand, the widespread use of independent packaging generates a large amount of waste packaging materials, and the large generation of these waste packaging materials leads to waste of resources and environmental damage.

[0003] To reduce the generation of waste packaging materials, taking advantage of the characteristics that dressings such as wound dressings and antipyretic patches, as well as masks, are in a sheet form, they can be first folded to reduce their volume and then independently packaged, which can reduce the amount of packaging materials used and also improve the portability after reducing the volume. For example, the Chinese invention patent with the authorization announcement number CN114084513B discloses an environmentally friendly and hygienic portable mask. By folding the mask before packaging, the size of the packaging bag is reduced, the amount of packaging materials used is reduced, the impact on the environment caused by packaging waste is reduced, and the portability is improved.

[0004] However, most of the related production equipment on the market currently does not have the function of folding masks. If folded manually, there are problems such as consuming manpower, low efficiency, uneven quality, and being easily contaminated. Summary of the Utility Model

The lower end of the pressing top plate 421 faces the folding opening 412. The upper end of the pressing top is connected to the pressing transmission mechanism. The pressing transmission mechanism can drive the pressing top plate 421 to insert downward into the folding opening 412 or drive the pressing top plate 421 to withdraw upward from the folding opening 412.

[0161] Working process: The raw material of the ear strap 50 is set in a roll. The head end of the ear strap 50 passes through the fixed gripper 224, and the part of the ear strap 50 near the head end is clamped by the fixed gripper 224 to prevent the head end of the ear strap 50 from falling. When the equipment runs, the sliding mechanism drives the movable gripper 223 to approach the fixed gripper 224, and the movable gripper 223 clamps the head end of the ear strap 50. Then, the fixed gripper 224 releases. After the sliding mechanism drives the movable gripper 223 to move away from the fixed gripper 224 by a certain distance, the fixed gripper 224 clamps the ear strap 50. At this time, a section of the ear strap 50 is grasped between the fixed gripper 224 and the movable gripper 223. The scissors 232 are started to cut the side of the ear strap 50 near the fixed gripper 224, forming an ear strap 50 with a certain length. At the same time, the lifting bracket 241 drives the two clamping tweezers 243 to quickly move downward and clamp near both ends of the ear strap 50. Then the movable gripper 223 also releases, and the turning mechanism 242 drives the clamping tweezers 243 to turn towards the conveying mechanism 12, so as to fold both ends of the ear strap 50 above the mask 60 placed on the conveying mechanism 12. Then, the lifting mechanism 252 drives the welding head 253 to press downward, making both ends of the ear strap 50 closely attached to the mask 60 and starting welding, so as to weld the ear strap 50 on the mask 60. Then, each part resets, and the conveying mechanism 12 conveys the welded mask 60 to the mask folding device 30.

[0162] After the ear straps 50 of the mask 60 are welded, the mask 60 is conveyed by the conveying mechanism 12 to the top surface of the bottom pushing head 321. At this time, the horizontal belt pushing motors 3124 of the two horizontal belt pushing mechanisms 312 are started, driving the gears 3126 to rotate. When the gears 3126 rotate, the racks 3125 are driven to extend, thereby driving the horizontal push plates 3121 of the two horizontal belt pushing mechanisms 312 to extend simultaneously towards the top surface of the bottom pushing head 321 and the side where the surface of the conveying mechanism 12 is located. The two horizontal push plates 3121 approach each other, thereby pushing the ear straps 50 on both sides of the mask 60 towards the middle of the mask 60 at the same time, so as to realize the folding of the ear straps 50 of the mask 60 towards the middle of the mask 60. Then, the horizontal belt pushing motor 3124 is started again and drives the gear 3126 to rotate in the reverse direction, driving the rack 3125 to retract, and conveying the mask 60 with the ear straps 50 already folded to the mask folding device 40 through the conveying mechanism 12.

[0163] The mask 60 with the ear straps 50 already folded is transported to the placement surface of the two guide plates 411 through the conveying mechanism 12, and then the downward pressing transmission mechanism is started. The downward pressing transmission mechanism drives the downward pressing top plate 421 to move downward. When the downward pressing top plate 421 moves downward to a certain extent, it will press on the mask 60 and bend the mask 60 downward. At this time, affected by the guiding inclined surface 3112, the mask 60 has a tendency to be bent into a V shape. As the downward pressing top plate 421 continues to move downward, the mask 60 will be pressed into the folding opening 412. At this time, affected by the guiding vertical surface, both sides of the mask 60 will stand up upward with the downward pressing top as the center. At this time, the downward pressing transmission mechanism drives the downward pressing top plate 421 to move upward away from the mask 60, thus completing the folding of the mask 60.

[0164] The mask processing equipment provided by the embodiment of the present application can realize the automation of mask welding, ear strap folding and mask folding. It eliminates operations such as manual cutting and placing of ear straps during the welding process, can improve the welding efficiency of mask ear straps, and has a good folding effect. It can avoid the problem of mask contamination caused by manual touch and also makes the mask welding process safer.

The conveying motor 124 transmits power to the conveying roller 122 through the belt pulley mechanism, so that the conveying roller 122 rotates. The conveying roller 122 drives the conveyor belt 121 to move through rotation, thereby driving the mask 60 placed on the mask 60 placement position to move.

[0169] See Figure 11 As shown in the figure, specifically, two guiding inclined plates 3111 are provided on the gantry frame 311. The two guiding inclined plates 3111 are symmetrically distributed on the opposite sides of the conveying mechanism 12. The guiding inclined plate 3111 includes a guiding inclined surface.

[0170] When the mask 60 is placed on the mask placement position of the conveying mechanism 12, both sides of the mask 60 extend beyond the conveyor belt 121 of the conveying mechanism 12. During the conveying process of the mask 60 by the conveying mechanism 12 after the previous process is completed, both sides of the mask 60 will contact the guiding inclined surface and move upward along the guiding inclined surface 3112, and then move to the guiding plane 3113, and then through the guiding plane 3113, move to the top surface of the bottom pushing head 321 and stay. At this time, after the horizontal pushing belt mechanism 312 performs an operation, the ear straps 50 of the mask 60 are folded towards the middle of the mask 60. Then, the vertical pressing belt cylinder 3134 is started to press down the vertical pressing belt supporting plate 3131, and the vertical pressing belt supporting plate 3131 drives the indentation pressing head 3135 to press down. The four indentation pressing heads 3135 on the two indentation components are exactly aligned with the four folding positions of the ear straps 50, so as to press out creases on the ear straps 50. During this process, when starting the vertical pressing belt cylinder 3134, the bottom pushing cylinder 322 can also be started to make the bottom pushing head 321 move upward, so as to press out creases on the ear straps 50.
