[0002] Masks are a type of sanitary product, generally worn on the nose and mouth to filter the air entering the nose and mouth to block harmful gases, odors, droplets, viruses and other substances. Masks are generally composed of non-woven fabrics, filter paper, nose bridge ribs and ear straps. Masks and ear straps need to be welded by a mask welding machine. The mask welding machine mainly uses ultrasonic high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the mask and ear strap surfaces rub against each other to form a fusion between the molecular layers.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5 The non-woven mask ear strap welding device shown in the figure comprises a base plate 1, and the four corners of the bottom of the base plate 1 are provided with support components, and the support components are used to support the base plate 1 in a horizontal state, and a reserved groove 2 is opened on the upper surface of the base plate 1, and a guide rod 3 is fixed between the relative inner walls of the reserved groove 2, and a support plate 4 is slidably sleeved on the outside of the guide rod 3, and a fixed block 5 is fixed on the upper surface of the support plate 4, and an electric push rod 6 is arranged on the fixed block 5, and a carrier block 7 is fixedly installed on the output end of the electric push rod 6, and a rack 8 is fixed on one side of the carrier block 7. The rack 8 is arranged parallel to the electric push rod 6. The upper surface of the support plate 4 is rotatably connected to the pillar 9 through a bearing. The outer part of the pillar 9 is fixedly sleeved with a gear 10. The rack 8 and the gear 10 are meshed with each other. A placement plate 11 is fixed to the top of the pillar 9. A mask groove 12 and two ear strap grooves 13 are opened on the placement plate 11. The mask groove 12 and the two ear strap grooves 13 are connected to each other. A mask welding machine body 18 is arranged on the bottom plate 1. Two clamping assemblies are arranged on the placement plate 11. The clamping assemblies are used to position the ear straps on the mask.

[0024] The electric push rod 6 is used to push the rack 8 to move. With the help of the mutual engagement of the rack 8 and the gear 10, the gear 10 can be driven to pull the pillar 9 to rotate, so that the pillar 9 drives the placement plate 11 to adjust the angle, thereby completing the conversion of the two ends of the mask placed in the mask groove 12, making the welding operation of the mask and the ear strap more convenient and labor-saving, saving the physical energy of the workers and improving the production efficiency.

[0025] A handle 14 is fixed on the upper surface of the support plate 4 , and two rollers 15 are arranged on the left and right sides of the support plate 4 .

[0026] The handle 14 and the four rollers 15 are used to push the support plate 4 to pull the placement plate 11 to move, so that the placement plate 11 can be away from the mask welding machine body 18 to facilitate workers to replace masks and ear straps.

[0027] Among them, a first magnet 16 is arranged on one side of the support plate 4 close to the main body 18 of the mask welding machine, and a second magnet 17 is fixed to the inner wall of the reserved groove 2, and the first magnet 16 and the second magnet 17 are magnetically connected.

[0028] With the cooperation of the first magnet 16 and the second magnet 17, it can be ensured that the placement plate 11 is accurately moved to the specified position below the mask welding machine body 18, ensuring the accuracy of welding the mask and the ear strap.

[0029] Among them, the clamping assembly includes a U-shaped seat 19, which is fixedly installed on the placement plate 11. The relative inner walls of the U-shaped seat 19 are rotatably connected to a rotating rod 20 through a bearing. A pressure rod 21 is fixed between the two rotating rods 20, and the pressure rod 21 is a "U"-shaped rod body structure.

[0030] The pressing rod 21 is rotated so that the pressing rod 21 can press the ear strap placed on the mask, so that the ear strap cannot be offset during the welding process, thereby ensuring the accuracy of welding the mask and the ear strap.

[0031] The support assembly includes a fixing tube 22 , which is fixedly mounted at the bottom of the base plate 1 , a stud 23 is inserted at the bottom of the fixing tube 22 , the fixing tube 22 is threadedly connected to the stud 23 , and a foot pad 24 is fixed at the bottom end of the stud 23 .

[0032] The studs 23 are screwed to adjust the overall length of the support assembly so that the base plate 1 can be placed horizontally with the help of the four support assemblies for better use.

[0033] How this utility works:

[0034] When in use, according to the shape of the bottom plate 1 placed on the desktop, the four studs 23 are screwed in sequence to adjust the lengths of the four supporting components, so that the bottom plate 1 can be kept in a horizontal state when parked on the desktop with the help of the four supporting components. The worker pulls the support plate 4 away from the mask welding machine body 18 with the help of the handle 14 and the four rollers 15. The worker places the mask inside the mask slot 12 and places the two ear straps at designated positions on the mask respectively. The worker rotates the two pressure rods 21 by hand so that the two pressure rods 21 press the ear straps on the mask to prevent the ear straps from shifting;

[0035] The worker manually pushes the support plate 4 to move toward the mask welding machine body 18. When the first magnet 16 and the second magnet 17 are attracted to each other, the movement of the support plate 4 is stopped. The mask welding machine body 18 can be manipulated to weld the mask to one of the ear straps. The electric push rod 6 is manipulated to push the rack 8 to move. With the help of the mutual engagement of the rack 8 and the gear 10, the gear 10 can be driven to pull the support 9 to rotate, so that the support 9 drives the placement plate 11 to adjust the angle, thereby completing the conversion of the two ends of the mask placed in the mask slot 12. The mask and the other ear strap are welded again with the help of the mask welding machine body 18. After that, the support plate 4 is pulled away from the rack 8, and the two pressure rods 21 are reversed to remove the mask after welding.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
