Description

Technical Field

[0001] The invention relates to the technical field of mask ear strap welding, in particular to a mask ear strap welding machine. Background Art

[0002] Masks are sanitary protective products typically worn over the nose and mouth to filter air entering the mouth and nose, blocking out droplets, dust, pollen, and other airborne particles. Masks typically use ear straps that hook onto the ears, ensuring the mask fits snugly over the nose and mouth. Therefore, one of the steps in the mask production process is to bend the ear straps into a semicircular shape and then weld their ends to the mask body.

[0003] In the prior art, mask ear strap welding machines all use an integrated structure, in which the wiring mechanism, welding device, and shearing device are all integrated into a relatively small area. The wiring mechanism includes several rotating parts and a wire pressing part. One end of the wire is wrapped around the outer wall of the rotating part. During each welding process, the steps are as follows: first, the rotating part rotates half a circle to pull out a section of wire; then the wire pressing part presses a certain position of the wire against the rotating part; then the welding device works to weld the pulled section of wire to the earmuff body located below the welding part and the wire; after welding is completed, the shearing device cuts the excess wire and the welding part returns to its initial position; then the rotating part continues to rotate half a circle, repeating the above working process. In such a welding device, the steps of pulling the wire, pressing the wire, welding, and cutting the wire must be performed sequentially. The connection between steps wastes a lot of time, making it difficult to further improve work efficiency. Summary of the Invention

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0036] Reference Figures 1 to 11The embodiment of the present invention proposes a mask ear loop welding machine, comprising a workbench 1, on which a welding device 2 is provided. The workbench 1 is provided with: a mask body conveyor line 31, an ear loop conveyor line bracket 300, a wiring mechanism 4 and a shearing mechanism 5. When the mask body conveyor line 31 is working, it conveys the mask bodies 100 one by one to the working area of the welding device 2; an ear loop conveyor line bracket 300 is provided with an ear loop conveyor line 32, and one side of the ear loop conveyor line 32 is provided with a plurality of clamping mechanisms 6 that move with it, each clamping mechanism 6 includes two clamping devices, and the two clamping devices are arranged at intervals so that the two can clamp the wire 200 at different positions respectively, and the other side of the ear loop conveyor line 32 is provided with a plurality of winding poles 3 that move with it. 21; The wiring mechanism 4 is located on one side of the ear band conveyor line 32. The wiring mechanism 4 includes a cycloid arm 41 and a cycloid driver 42 capable of driving the cycloid arm 41 to perform reciprocating motion. The cycloid arm 41 is provided with a wire tube located above the ear band conveyor line 32. The inner hole of the wire tube forms a wire groove 411. When the cycloid arm 41 performs reciprocating motion, it cooperates with the movement of the ear band conveyor line 32 to arrange the wire 200 output from the wire groove 411 in a serpentine shape between the winding column 321 and the wire clamping mechanism 6; the shearing mechanism 5 is located on one side of the ear band conveyor line 32 and is used to cut the wire 200 between the two wire clamping devices of the wire clamping mechanism 6 so that an ear band is formed between every two adjacent wire clamping mechanisms. The cut ear band is transported to the working area of the welding device 2 by the ear band conveyor line 32.

[0037] The mask body conveyor line 31 and the ear strap conveyor line 32 can be equipped with chain conveyors, belt conveyors, or other devices. They are arranged one above the other, rotating in opposite directions. For example, the ear strap conveyor line 32 can be placed above the mask body conveyor line 31, with the mask body conveyor line 31 rotating counterclockwise and the ear strap conveyor line 32 rotating clockwise. To position the mask body 100, multiple trays 311 are spaced apart on the mask body conveyor line 31. Positioning posts 312 are located at the edges of the trays 311 to help position the mask body 100.

[0038] Reference Figures 4 to 6 The wire clamping mechanism 6 includes a winding seat 60, and two wire clamping rods 61 are movably connected to the winding seat 60. Each wire clamping rod 61 and the side wall of one side of the winding seat 60 form a wire clamping device. The winding seat 60 is also provided with a power component that can drive the two wire clamping rods 61 to switch between the clamping and release positions.

[0039] Preferably, the two wire clamping rods 61 are respectively hinged to the left and right sides of the winding seat 60, and a notch 601 is provided on the front side wall of the winding seat 60. The power component includes an active part 62 which is movably arranged on the winding seat 60 up and down. A transmission mechanism is provided between the active part 62 and the wire clamping rod 61, which can drive the wire clamping rod 61 to rotate when the active part 62 moves up and down. A locking device is provided between the winding seat 60 and the active part 62, which can lock the active part 62 when the wire clamping rod 61 is in a clamped state and an unfolded state.

[0040] In a preferred embodiment of the present invention, the transmission mechanism includes an inclined groove 611 provided on the wire clamping rod 61, and a first push shaft 63 provided on the active member 62, and the first push shaft 63 is inserted into the inclined groove 611. The first push shaft 63 can be a fixed shaft or a rotating shaft that can rotate relative to the active member 62. The locking device includes a first bayonet 621 provided on the active member 62, a second bayonet 622 provided on the active member 62, and a spring positioning bead 64 provided on the winding seat. When the wire clamping rod 61 is in a clamped state, the spring positioning bead 64 is engaged with the first bayonet 621, and when the wire clamping rod 61 is in an open state, the spring positioning bead 64 is engaged with the second bayonet 622.

[0041] In certain embodiments of the present invention, the locking device may also adopt other structural forms. For example, the active member 62 may also be movable up and down, and the spring positioning bead 64 may be provided on the active member 62, and two corresponding bayonets may be provided on the winding seat. The wire clamping mechanism 6 may also adopt other structural forms. For example, the active member 62 may be provided as a gear that can rotate on the winding seat, and the gear and the wire clamping rod 61 may be meshed with gears, and the wire clamping rod 61 may be driven to rotate during the rotation of the active member 62; or the active member 62 may be a rack that can move up and down, and one end of the wire clamping rod 61 may be provided with a gear that meshes with the rack.

[0042] Reference Figure 3 The structure for driving the active member 62 to move up and down is as follows: the ear band conveyor line bracket 300 or the workbench 1 is provided with a first pushing member 11 and a second pushing member 12 located on the travel path of the clamping mechanism 6. The first pushing member 11 is provided with a first pushing inclined surface 111. When the clamping mechanism 6 moves to the position where the first pushing member 11 is located, the first pushing inclined surface 111 presses the active member 62 to drive the clamping rod 61 to clamp. The second pushing member 12 is provided with a second pushing inclined surface 121. When the clamping mechanism 6 moves to the position where the second pushing member 12 is located, the second pushing inclined surface 121 presses the active member 62 to drive the clamping rod 61 to loosen. In order to reduce friction, the lower end of the active member 62 is pivotally connected to a roller 65. When the roller 65 rolls along the first pushing inclined surface 111, it drives the active member 62 to move downward, so that the clamping rod 61 is clamped.

[0043] Reference Figure 7The wiring mechanism 4 further includes a wiring rack 43, a cycloid driver 42 that is a reversible motor, and a cycloid arm 41 that is swingably mounted on the wiring rack 43. The wiring rack 43 is provided with a traction device capable of pulling the wire 200, and a temporary storage device for temporarily storing the wire 200 is provided between the traction device and the cycloid arm 41. In certain embodiments of the present invention, the cycloid arm 41 can also be configured to reciprocate above the ear strap conveyor line.

[0044] Preferably, the traction device includes two traction wheels 44 and a traction motor 45 capable of driving the two traction wheels 44 to rotate in opposite directions. The outer side walls of the two traction wheels 44 are close to each other so that the wire 200 can be clamped and pulled therebetween.

[0045] Preferably, the temporary storage device includes a counterweight wheel 46 that can be driven by its own weight to move downward relative to the wiring rack 43. The outer wall of the counterweight wheel 46 is provided with a wire groove 461 that can be wound around the wire 200. When the two traction wheels 44 rotate together, the wire 200 is pulled out from the external wire 200 coil and into the temporary storage device. During the process of pulling the wire 200, the counterweight wheel 46 gradually descends, temporarily storing the pulled wire 200. Then, the cycloidal arm 41 swings, outputting the temporarily stored wire 200, which is wound between the wire clamping mechanism 6 and the winding post 321 for use in the production of ear straps.

[0046] In order to prevent the counterweight wheel 46 from detaching from the wiring rack 43 and falling during operation, a circumferential limiting groove 462 is provided on the outer wall of the counterweight wheel 46, and two vertical guide rods 47 are provided on the wiring rack 43. The two guide rods 47 are respectively embedded in the limiting groove 462 from both sides to limit the counterweight wheel 46 from detaching from the wiring rack 43.

[0047] Reference Figure 8 and Figure 9The shearing mechanism 5 includes a scissor seat 51 fixedly arranged on the workbench 1, and a first movable seat 52 that can move up and down relative to the scissor seat 51. A limit device that can limit the maximum stroke of the first movable seat 52 moving downward is provided between the scissor seat 51 and the first movable seat 52. The shearing mechanism 5 also includes a second movable seat 53 and a shearing driver 54 that can drive the second movable seat 53 to move up and down relative to the scissor seat 51. The first movable seat 52 and the second movable seat 53 are connected by a compressible elastic member 55 so that the second movable seat 53 can drive the first movable seat 52 to move up and down together. A shearing knife group is provided on the first movable seat 52. The second movable seat 53 and the shearing knife group are connected by a transmission device so that when the second movable seat 53 moves up and down relative to the first movable seat 52, it can drive the shearing knife group to perform a shearing action. The shearing driver 54 is preferably a cylinder, and the elastic member 55 is preferably a spring. The advantage of such a design is that a single driver can be used to first move the shearing knife group to the position of the wire 200 to be sheared within a one-way stroke cycle, and then perform a shearing action to cut the wire 200 after it is in place. When the wire clamping mechanism 6 with the wire 200 clamped therein moves to the working area of the shearing mechanism 5, the shearing driver 54 drives the second movable seat 53 to move downward, driving the first movable seat 52 to move downward together. After the first movable seat 52 moves into place, it is limited by the limiting device, and then the second movable seat 53 continues to move downward, compressing the elastic member 55. At this time, the power of the second movable seat 53 is transmitted to the shearing knife group through the transmission device, driving the shearing knife group to perform the shearing action.

[0048] In a preferred embodiment of the present invention, a guide sleeve 511 is provided on the scissor seat 51, a guide post 521 that cooperates with the guide sleeve 511 is provided on the first movable seat 52, and a limiting device is a protrusion 522 provided on the upper portion of the guide post 521. When the first movable seat 52 moves downward, the protrusion 522 abuts against the end surface of the guide sleeve 511 to limit the first movable seat 52. The shearing knife assembly includes a fixed blade 56 fixed to the first movable seat 52 and a movable blade 57 hinged on the first movable seat 52. The transmission device includes a knife groove 571 provided on the movable blade 57 and a push rod 58 connected to the second movable seat 53. The push rod 58 is provided with a second push shaft 581 at one end. The second push shaft 581 is inserted into the knife groove 571 so that the second push shaft 582 can drive the movable blade 57 to rotate relative to the fixed blade 56 when the second push shaft 582 moves up and down relative to the fixed blade 56.

[0049] In certain embodiments of the present invention, the shearing knife group and the transmission device may also adopt the following structural form. For example, the shearing knife group adopts two blades hinged on the first movable seat 52, and both blades are provided with a knife groove 571. The transmission device includes a push rod 58 arranged on the second movable seat 53, and the push rod 58 is connected to two second push shafts 581. The two second push shafts 581 are respectively inserted into the knife groove 571 of one blade.

[0050] In order to weld two ear straps on the mask body 100 at the same time, the ear strap conveying line 32, the wiring mechanism 4 and the cutting mechanism 5 can be set into two groups, wherein the two ear strap conveying lines 32 are parallel to each other.

[0051] Reference Figure 1 、 Figure 3 and Figure 11 The working principle of the present invention is as follows: first, the wiring mechanism 4 arranges the wire 200 in a serpentine shape between the winding column 321 and the clamping mechanism 6; then the clamping mechanism 6 is transported forward along with the ear band conveying line 32, and under the action of the first pushing member 11, the two clamping rods 61 of each clamping mechanism 6 clamp the wire 200; then the clamping mechanism 6 is transported to the working area of the shearing mechanism 5, and the shearing knife group of the shearing mechanism 5 extends into the notch 601 of the winding seat 60, and cuts a section of the wire 200 between the two clamping rods 61, so that a section of the wire 200 can be cut between every two adjacent clamping mechanisms 6. A section of ear strap is formed, and both ends of the cut ear strap are exposed outside the winding seat 60 of the clamping mechanism 6; finally, this section of ear strap is transported to the working area of the welding device 2 together with the corresponding clamping mechanism 6 and the winding column 321; the mask body conveying line 31 and the ear strap conveying line 32 run synchronously and in opposite directions, and their linear speeds are equal. When the ear strap is transported to the working area of the welding device 2, the corresponding mask body 100 is also transported to the working area of the welding device 2, and then the welding device 2 welds the mask body 100 and the free end of the ear strap together. After welding is completed, under the action of the second push-up seat, the two clamping rods 61 of the clamping mechanism 6 are opened, so that the ear strap and the clamping mechanism 6 are loosened, and the welded ear strap and mask body 100 can be moved to the next station along the mask body conveying line 31.

[0052] Reference Figure 10 The welding device 2 includes a welding frame 21 fixedly mounted on the workbench 1. The welding frame 21 is provided with a welding piece 22 and a welding driver 23 capable of driving the welding piece 22 up and down. The welding driver 23 is preferably a cylinder. Two welding heads 221 are spaced apart at the lower end of the welding piece 22. The two welding heads 221 correspond to the positions of the free ends of the two ear straps clamped by the same clamping mechanism 6. Each time the welding piece 22 is pressed down, it aligns with the free ends of the two ear straps and welds the free ends of the two ear straps to the two mask bodies 100.

[0053] Compared with the prior art, the mask ear strap welding machine of the present invention separates the process of producing ear straps, and performs the production of ear straps while welding, which saves the connection time between multiple steps and is conducive to further improving work efficiency.

[0054] The above are only preferred implementation methods of the present invention. As long as the technical solutions of the present invention are achieved by basically the same means, they all fall within the protection scope of the present invention.
