Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0041] In one embodiment of the present invention, such as Figures 1-3 and Figure 5 As shown, a folding mask adjustment buckle threading mechanism is provided, including a mounting frame 10, an ear loop pulling device 20, an ear loop pushing device 30, a cutting device 40, and an upper buckle device 50. The mounting frame 10 is a frame structure. The ear loop pulling device 20 and the ear loop pushing device 30 are located on the same side, which facilitates the ear loop pushing device 30 to push and deform the ear loop pulled out from the ear loop pulling device 20, so that the ear loop is close to the side of the ear loop pin 5311. The cutting device 40 is located above the end of the ear loop pulling device 20, at the input end of the ear loop, and cuts and separates the ear loop after it has been pulled to a certain length. The ear loop pulling device 20, the ear loop pushing device 30, the cutting device 40, and the upper buckle device 50 are all fixedly installed in the mounting frame 10. The ear loop pulling device 20 and the ear loop pushing device 30 are arranged opposite to the upper buckle device 50, and the ear loop pulling device 20 and the ear loop pushing device 30 are arranged opposite to the upper buckle device 50. The working height is located at the bottom of the upper buckle device 50, used to push the ear loop to the side of the ear loop pin 5311, ensuring that the upward movement of the ear loop pin 5311 can hook the ear loop. The ear loop pushing device 30 is located below the ear loop pulling device 20. The ear loop pulling device 20 consists of a sliding seat, a movable gripper, and a positioning clamp. The sliding seat is fixedly installed in the mounting frame 10. The movable gripper and the positioning clamp are both slidably installed on the sliding seat. The positioning clamp is set at one end near the sliding seat. The movable gripper moves repeatedly, and the ear loop passes through the positioning clamp. The movable gripper grabs the end of the ear loop and moves to pull out a fixed length of ear loop. After the fixed length of ear loop is pulled out, the positioning clamp is fixed and limited. The horizontal height is located below the bottom plane of the sliding seat long plate of the ear loop pulling device 20. The ear loop is pushed to be close to the ear loop pin 5311 by the ear loop pushing device 30 located below the sliding seat long plate.

[0042] The ear loop pin 5311 hooks the ear loop and moves it upward, causing the ear loop to pass through the adjusting buckle located in the positioning device 51, completing the ear loop fastening installation. Then, in conjunction with the ear loop welding device, the two ends of the pulled ear loop are clamped. The cutting device 40 then cuts the ear loop to obtain an ear loop with a sleeve. The ear loop welding device assembles the ear loop onto the mask body. The upper buckle device 50 disengages, releasing the ear loop, completing the assembly of the ear loop with the adjusting buckle. The upper buckle device 50 has a positioning device 51 at its bottom, which receives and fixes the adjusting buckle. Working in conjunction with the ear loop pin 5311 of the upper buckle device 50, the ear loop adjusting buckle is assembled. The positioning device 51 is connected to the ear loop pulling device 20. The ear loop pusher 30 and the positioning device 51 are positioned opposite each other. The positioning device 51 is located above the moving path of the ear loop pusher 30, so that the downward-moving ear loop pin 5311 can overlap with the moving path of the ear loop pusher 30. The ear loop pin 5311 of the upper buckle device 50 moves up and down through the positioning device 51. The side of the ear loop pin 5311 near the pin tip has an inclined slot that gradually slopes downward from the outside to the inside, which is used to hook the ear loop upward through the adjustment buckle located in the positioning device 51. The ear loop pin 5311 moves up and down to hook the ear loop pushed by the ear loop pusher 30 through the adjustment buckle, thus completing the adjustment buckle assembly.

[0043] The folding mask adjustment buckle threading mechanism of this invention is assembled from a mounting frame 10, an ear loop pulling device 20, an ear loop pushing device 30, a cutting device 40, and an upper buckle device 50. The ear loop pulling device 20 is used to stretch the conveyed ear loops to a fixed length. The ear loop pushing device 30 is used to push the ear loops to deform their shape. The cutting device 40 is used to cut ear loop segments of equal length. The upper buckle device 50 is used to receive the adjustment buckle and pass the ear loop through it. Therefore, the ear loops stretched by the ear loop pulling device 20 are cut by the cutting device 40. The ear loop pulling device 20 is also equipped with a clamp to hold the remaining ear loop ends, preventing the ear loops from falling off after cutting and affecting assembly. The ear loop pushing device 30 pushes the ear loops of a fixed length pulled by the ear loop pulling device 20 towards the barb on the ear loop pin 5311 after it falls. The front end of the push plate 31 of the ear loop pushing device 30 is provided with two upwardly bent baffles. The top of the device bends and extends to form a limiting plate parallel to the push plate 31. The limiting plate and the push plate 31 are located on opposite sides of the baffle, and the end of the limiting plate is bent upward. The two baffles are located at both ends of the edge of the push rod. The ear loop pushing device 30 pushes the push plate 31 to move, and the two baffles block the ear loop. The two limiting plates prevent the ear loop from moving upward and falling off. At the same time, the gap between the two baffles forms a clearance to avoid the falling ear loop needle 5311. The ear loop is pressed onto the ear loop needle 5311. The ear loop needle 5311 moves upward, hooks the ear loop, and drives the ear loop to pass through the positioning device 51 in the buckling device 50. At the same time, it passes through the adjustment buckle located in the positioning device 51, completing the ear loop buckling action. The positioning device 51 continuously receives the adjustment buckle, realizing the automation of ear loop buckling. Through the combination and installation of the above components, the automatic cyclic buckling of the mask ear loop is realized, thereby improving the assembly efficiency of the adjustment buckle.

[0044] In another embodiment of the invention, such as Figure 1 As shown in Figure 5, the upper buckle device 50 also includes a mounting plate 52 and a pull-out device 53. The mounting plate 52 is placed vertically, and the pull-out device 53 is used to hook the ear loop to complete the adjustment buckle assembly. The mounting plate 52 is fixedly installed in the mounting frame 10, the pull-out device 53 is fixedly installed on the side of the mounting plate 52, and the positioning device 51 is fixedly installed below the mounting plate 52. The pull-out device 53 is located above the positioning device 51. The moving end of the pull-out device 53 moves up and down to drive the ear loop pin 5311 to pass through the positioning device 51 and move up and down to drive the ear loop to complete the adjustment buckle assembly. The ear loop pin 5311 can be moved to disengage from the positioning device 51, so that the unhooking device 532 on the pull-out device 53 can rotate to disengage the ear loop after buckling.

[0045] In another embodiment of the invention, such as Figure 2 ~ 3 and Figure 5As shown, the pull-out device 53 also includes a pull-out cylinder 531 and a release device 532. The pull-out cylinder 531 is used to pull the ear loop pin 5311 up and down to complete the hooking and fastening of the ear loop. The release device 532 is used to separate the ear loop from the ear loop pin 5311 after fastening. Both the pull-out cylinder 531 and the release device 532 are fixedly installed on the side of the mounting plate 52. The mounting surfaces of the pull-out cylinder 531 and the release device 532 are adjacent to each other, and the moving end of the pull-out cylinder 531 faces downward. The top of the ear loop pin 5311 is fixed to the moving end of the pull-out cylinder 531. The fixed connection enables the up-and-down movement of the ear loop pin 5311 to complete the ear loop hooking and fastening. The bottom of the ear loop pin 5311 can move upward to above the rotating end of the loosening device 532. When the rotating end of the loosening device 532 rotates and is in close contact with the mounting plate 52, it makes way for the movement of the ear loop pin 5311. After the ear loop pin 5311 completes the ear loop hooking and fastening, the loosening device 532 rotates, pushing the ear loop hanging on the pin head of the ear loop pin 5311 upward and detaching it from the ear loop pin 5311. Then, the positioning device 51 releases the fixing of the adjusting buckle, and the adjusting buckle is released, resulting in an ear loop equipped with the adjusting buckle.

[0046] In another embodiment of the invention, such as Figures 2-5As shown, the release device 532 includes a release cylinder 5321 and a U-shaped ring 5322. The two ends of the U-shaped ring 5322 are rotatably connected to the two sides of the mounting plate 52, respectively, for rotating upwards to release the ear loop on the ear loop pin 5311. The U-shaped ring 5322 includes a first support rod, a second support rod, and a crossbar. Both the first and second support rods are bent and mirror-symmetrically arranged, with the first and second support rods respectively connected to the two ends of the crossbar. The other ends of the first and second support rods are rotatably connected to the two sides of the mounting plate 52. A rotatable connection hole is provided in the middle area of ​​the first and second support rods for rotatably connecting with the moving end of the release cylinder 5321. The release cylinder 5321 pulls this point, causing the first and second support rods to rotate around the rotatable connection point with the mounting plate 52. Since the crossbar is located at the other end of the first and second support rods, when the first and second support rods rotate... The crossbar rotates, allowing it to switch between its position against the side of the mounting plate 52 and the ear loop. The smooth, rounded side of the crossbar facilitates changes in the contact surface between it and the ear loop. The release cylinder 5321 is fixedly mounted on the side of the mounting plate 52, with a fixing plate at its end. The fixing plate is fixedly connected to the side of the mounting plate 52, while the body end of the release cylinder is rotatably connected to the fixing plate. When the moving end of the release cylinder 5321 extends or retracts, it can simultaneously change its angle with the U-shaped ring 5322, preventing it from getting stuck due to angle issues. The moving end of the release cylinder 5321 is rotatably connected to the side of the U-shaped ring 5322, and the rotation connection point of the moving end of the release cylinder 5321 is close to the end of the U-shaped ring 5322. This adjacent arrangement of the two rotation connection points effectively shortens the extension / retraction path of the moving end of the release cylinder 5321.

[0047] In another embodiment of the invention, such as Figures 2-4 and Figure 5 As shown, a moving device 521 is provided on the side of the mounting plate 52. The guide rail of the moving device 521 is fixedly installed on the side of the mounting plate 52, and the guide rail is vertically arranged. The moving device 521 is located between the mounting plate 52 and the ear loop pin 5311. The top of the moving block of the moving device 521 is fixedly connected to the moving end of the cable pull cylinder 531, and the bottom of the moving block of the moving device 521 is fixedly connected to the top of the ear loop pin 5311. The moving end of the cable pull cylinder 531 drives the ear loop pin 5311 to move up and down by pushing the position of the moving block. The moving device 521 is used to guide the up and down movement of the ear loop pin 5311 and prevent deviation.

[0048] In another embodiment of the invention, such as Figure 2 and Figure 5As shown, a sensor 522 is provided on the side of the mounting plate 52, and a sensor plate 523 is fixedly installed on the moving block of the moving device 521 to sense the downward position of the moving device 521. When the moving block of the moving device 521 moves downward to the preset position, the sensor 522 senses the sensor plate 523 and transmits the signal to the cable pull cylinder 531. The cable pull cylinder 531 stops moving and waits for the ear loop pusher 30 to push the ear loop to be close to the side of the ear loop pin 5311. The cable pull cylinder 531 then moves upward, driving the ear loop pin 5311 to move upward. Through the slot on the inclined ear loop pin 5311, the ear loop moves slowly and gradually into the slot under the action of the contraction force, completing the ear loop selection. The selected ear loop passes through the adjustment buckle located in the positioning device 51 to complete the ear loop fastening.

[0049] In another embodiment of the invention, such as Figures 2-3 and Figure 5 As shown, the positioning device 51 includes a positioning block 511, a first positioning plate 512, a second positioning plate 513, a U-shaped plate 514, and two positioning cylinders 515. The positioning block 511 cooperates with the first positioning plate 512 and the second positioning plate 513 to limit the position of the input adjustment buckle, preventing it from moving up or down during the ear loop insertion process. The U-shaped plate 514 is fixedly installed on the bottom of the mounting plate 52. The positioning block 511 has an input hole 5111 and a threading hole 5112. The adjustment buckle is input through the input hole 5111, and the ear loop pin 5311 passes through the threading hole 5112 to complete the ear loop selection. The buckle is inserted through the vertically positioned positioning block 511, and the central axis of the buckle 5112 coincides with the moving path of the ear loop pin 5311. The vertical setting allows the buckle 5112 to perfectly match the moving path of the ear loop pin 5311. The input hole 5111 is inclined, gradually tilting downwards from the outside to the inside, and the bottom end of the input hole 5111 is connected to the buckle 5112, thereby ensuring that the input adjustment buckle can fall into the buckle 5112. The buckle 5112 is provided with a ring-shaped limiting protrusion. When the ear loop pin 5311 drives the ear loop to pass through the adjustment buckle from bottom to top.

[0050] The top of the adjusting buckle abuts against the limiting protrusion, thereby restricting the movement of the adjusting buckle and completing the ear loop fastening action. The first positioning plate 512 and the second positioning plate 513 are respectively rotatably mounted on the two sides of the positioning block 511, and the bottom ends of the first positioning plate 512 and the second positioning plate 513 are combined to form a positioning groove. The positioning groove communicates with the thread hole 5112, and the bottom of the positioning groove is provided with a through hole for the ear loop pin 5311 to pass through. Through the rotational connection of the first positioning plate 512 and the second positioning plate 513, the positioning groove appears and separates as the first positioning plate 512 and the second positioning plate 513 rotate, coordinating with the feeding and unloading action of the adjusting buckle. When the first positioning plate 512 and the second positioning plate 513 are combined together, the positioning groove is used to receive the adjusting buckle that falls out of the thread hole 5112. A through hole is provided for the ear loop pin 5311 to pass through, which on the one hand restricts the adjustment buckle that has fallen into the positioning groove from falling further, and on the other hand forms a clearance on the moving path of the ear loop pin 5311 to avoid affecting the ear loop hooking action of the ear loop pin 5311. Two positioning cylinders 515 are respectively fixedly installed on the two side plates of the U-shaped plate 514, and the moving ends of the two positioning cylinders 515 are respectively set through the side plates of the U-shaped plate 514. The moving ends of the two positioning cylinders 515 are respectively connected to the top side of the first positioning plate 512 and the second positioning plate 513. Through the setting of the U-shaped plate 514, the two positioning cylinders 515 are set opposite to each other, and the first positioning plate 512 and the second positioning plate 513 are rotated respectively, thereby realizing the combination and separation of the first positioning plate 512 and the second positioning plate 513, that is, the combination and separation of the positioning groove, completing the feeding and unloading of the adjustment buckle.

[0051] In another embodiment of the invention, such as Figure 2 and Figure 5 As shown, the positioning block 511 has two opposing mounting side plates 5113 on both sides. The first positioning plate 512 and the second positioning plate 513 are rotatably mounted between the two sets of mounting side plates 5113. By setting two sets of mounting side plates 5113, mounting positions are provided for the first positioning plate 512 and the second positioning plate 513. The rotation points of the first positioning plate 512 and the second positioning plate 513 can be moved as far away from the positioning block 511 as possible. This allows for control of the gap between the bottom ends of the first positioning plate 512 and the second positioning plate 513 when they rotate apart. This prevents the adjustment buckle from getting stuck between the first positioning plate 512 and the second positioning plate 513 when the material is unloaded due to insufficient separation gap between the bottom ends of the first positioning plate 512 and the second positioning plate 513.

[0052] In another embodiment of the invention, such as Figure 6As shown, the folding mask adjustment buckle threading mechanism also includes a vibrating discharge device 60. The vibrating discharge device 60 is used to adjust the direction and sort the adjustment buckles stacked together. The vibrating discharge device 60 is equipped with a vibrating plate 61 and a conveying device 62. The vibrating plate 61 vibrates and sorts the adjustment buckles. The conveying device 62 receives the adjustment buckles after they have been sorted and adjusted by the vibrating plate 61, and then outputs them one by one to the input hole 5111 for ear loop threading. The conveying device 62 is connected to the vibrating plate 61 and the positioning device 51 by pipes. The adjustment buckles are transferred through the pipes, which can prevent the orientation of the adjustment buckles from changing during the transfer and conveying process, thereby ensuring the yield rate.

[0053] In another embodiment of the invention, such as Figures 7-8 As shown, the conveying device 62 includes a mounting box 621, a protective cover 622, a conveying block 623, and a moving cylinder 624. The protective cover 622 is used to shield the discharge part of the conveying device 62, preventing the discharge part from being affected by external factors and preventing the adjusting buckle from jumping out during conveying. The conveying block 623 is used to receive the moving adjusting buckle. The moving cylinder 624 provides the moving power for the conveying block 623. The mounting box 621 is fixedly mounted on the vibrating discharge device 60, and the mounting box 621 is provided with a moving groove. The moving groove is used to orient the moving path of the conveying block 623. The protective cover 622 covers the top of the moving groove to shield the movement of the conveying block 623. The conveying block 623 is placed in the moving groove and moves back and forth in an orderly manner in the moving groove, thereby completing the repetitive actions of receiving and conveying the adjusting buckle. The cross-section of the conveying block 623 is convex, and a sliding groove is also provided at the bottom. The convex shape is matched with the corresponding shape on the mounting box 621 for movement. The groove can effectively prevent the conveyor block 623 from detaching from the moving groove during movement. The chute setting can provide a certain directional raised track at the bottom of the moving groove to further guide the movement path of the conveyor block 623. The moving cylinder 624 is fixedly installed at one end of the mounting box 621, and the moving end of the moving cylinder 624 passes through the mounting box 621 and is fixedly connected to the conveyor block 623. The moving cylinder 624 pushes the conveyor block 623 to move along the path of the moving groove. The conveyor block 623 is provided with a groove for placing the adjusting buckle. The mounting box 621 has an air inlet and a discharge outlet on opposite sides, and the two ends of the groove can be moved to coincide with and connect with the air inlet and the discharge outlet, respectively. When the conveyor block 623 moves to the point where the groove is the same as the air inlet and the discharge outlet, the air inlet and the discharge outlet are connected. One end of the air inlet is connected to an air pipe. The air pipe pushes the adjusting buckle placed in the groove into the pipe connected to the discharge outlet and transfers it to the input hole 5111 for buckling the ear loop.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
