[0002] Combat boots play a vital role in military operations. The tongue of combat boots not only needs to provide good protection, but also needs to be comfortable to wear. In the manufacturing process of combat boots, the hemming of the tongue is a key link, which is mainly to wrap the edge of the tongue with an hemming strip and then sew it with a sewing machine to complete the hemming.

[0003] However, the angle of the exit of the existing hemming device is fixed. When hemming the tongues of combat boots of different sizes or thicknesses, the thickness of the hemming strips required is also different. However, since the angle of the existing hemming device is fixed and cannot be adjusted according to the thickness of the hemming strip, this may cause the hemming strip to be unable to fit closely to the edge of the tongue during the hemming process, thereby affecting the quality of the hemming and causing uneven hemming.

[0033] 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 of 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.

[0034] like Figure 1 - Figure 6 As shown, the utility model provides: a combat boot tongue hemming device, comprising a sewing machine body 10, the sewing machine body 10 is a prior art, and a needle seat 11 and a machine needle 12 used in conjunction with the sewing machine body 10, after the edge of the combat boot tongue is wrapped by the hemming strip, the combat boot tongue is sewn together with the hemming strip by the needle seat 11 and the machine needle 12, thereby completing the hemming of the combat boot tongue, and the sewing machine body 10 is equipped with an hemming mechanism 20 capable of guiding the hemming strip;

[0035] The hemming mechanism 20 includes a frame 21 placed on the sewing machine body 10, a lower guide frame 22 is fixedly installed on one side of the frame 21, an upper guide frame 23 is placed on the top of the lower guide frame 22, and limit rods are arranged inside the lower guide frame 22 and the upper guide frame 23 so that the upper guide frame 23 does not rotate when rising, a placement frame 24 is fixedly installed on one side of the lower guide frame 22, and the placement frame 24 is used to place the tongue of combat boots, a mounting assembly 25 is installed on one side of the frame 21, and a lifting assembly 26 for adjusting the position of the upper guide frame 23 is also installed on the lower guide frame 22, and a conveying assembly 27 for conveying the hemming strip is also installed on the frame 21.

[0036] like Figure 4 As shown, the mounting assembly 25 includes a mounting frame 251 placed on the sewing machine body 10, the mounting frame 251 and the sewing machine body 10 are fixed by screws, a moving frame 252 is installed on the top of the mounting frame 251 by screws, and a connecting frame 253 is fixedly installed between the moving frame 252, the frame 21 and the lower guide frame 22;

[0037] When in use, first install the hemming mechanism 20, install the mounting frame 251 on the sewing machine body 10 by screws, then place the movable frame 252 on the mounting frame 251, and adjust the positions of the frame 21, the lower guide frame 22 and the upper guide frame 23 by moving the movable frame 252, so that the lower guide frame 22 and the upper guide frame 23 correspond to the edge of the needle seat 11, and then fix the movable frame 252 and the mounting frame 251 together by screws.

[0038] like Figure 5 As shown, the lifting assembly 26 includes a rotating rod 261 rotatably mounted on the top of the connecting frame 253, and a ratchet 262 is mounted on the rotating rod 261 through a bearing. The ratchet 262 is a prior art. When the rotating rod 261 rotates clockwise, the tooth claw inside the ratchet 262 is driven to rotate clockwise through the bearing, and the tooth claw will engage with the teeth of the inner ring of the ratchet 262 in the clockwise direction, thereby driving the ratchet 262 to rotate as a whole;

[0039] When the rotating rod 261 rotates counterclockwise, the toothed claw inside the ratchet 262 is driven to rotate counterclockwise through the bearing, and the toothed claw is disengaged from the teeth of the inner ring of the ratchet 262, so that the ratchet 262 will not be driven to rotate as a whole;

[0040] One side of the lower guide frame 22 is rotatably connected to a plurality of connecting rods 263, on which a gear 264 is fixedly mounted, a synchronous belt 265 is meshed between the ratchet 262 and the plurality of gears 264, and the ratchet 262 and the plurality of gears 264 are driven by the synchronous belt 265 so as to synchronously rotate, and a reciprocating thread groove 266 is provided on the surface of the connecting rod 263.

[0041] In further detail, the upper guide frame 23 is threadedly mounted on the reciprocating thread groove 266 , and the reciprocating thread groove 266 enables the upper guide frame 23 to reciprocate up and down, and the height of the connecting rod 263 is smaller than the rotating rod 261 .

[0042] In further detail, one end opening of the lower guide frame 22 and the upper guide frame 23 is set as an inclined plane, and an angle is formed between the two inclined planes. When the edge strip passes through the angle, the two ends will gradually get closer, so that the edge strip forms a U shape. At this time, when the tongue of the combat boot is placed on the placement frame 24, the edge of the tongue of the combat boot is located inside the edge strip.

[0043] When it is necessary to use hemming strips of different thicknesses to hem the tongue of combat boots, the distance between the required angles needs to be changed. By rotating the rotating rod 261 clockwise, the bearing drives the ratchet 262 to rotate as a whole. At this time, through the meshing and the transmission of the synchronous belt 265, the two gears 264 will also rotate synchronously with the ratchet 262. The connecting rod 263 will also rotate through the gear 264, so that the upper guide frame 23 rises through the reciprocating thread groove 266, thereby changing the angle distance between the upper guide frame 23 and the lower guide frame 22;

[0044] Through the continuous rotation of the connecting rod 263, the upper guide frame 23 will descend after rising to the top through the reciprocating thread groove 266, thereby realizing reciprocating motion.

[0045] There is a gap between the frame 21 and the lower guide frame 22 and the upper guide frame 23. After the edging strip is transported by the conveying assembly 27, one end of the edging strip will be located in the gap. At this time, the edging strip is manually pulled and passes through the angle between the lower guide frame 22 and the upper guide frame 23.

[0046] like Figure 6 As shown, the conveying assembly 27 includes a plurality of rotating shafts 271 rotatably mounted on the frame 21, and a belt 272 is connected between two rotating shafts 271, and the belt 272 can rotate through the transmission of the rotating shaft 271, and a vertical plate 273 is fixedly mounted on one side of the belt 272, and the belt 272 will also drive the vertical plate 273 to move when moving, and a ring 274 is rotatably connected to one side of the vertical plate 273, and one end of the edge strip is passed through the ring 274, and the edge strip is conveyed by the rotation of the belt 272, and a plurality of arc blocks 275 are fixedly mounted inside the frame 21, and the surface of the edge strip is smoothed by the arc blocks 275 so that the edge strip will not be wrinkled, and a support frame 276 is fixedly mounted on one side of the frame 21;

[0047] When in use, the edging strip is passed through the support frame 276, which serves as a guide and makes the edging strip flat. Then, one end of the edging strip is passed through the ring 274, and the rotating rod 261 is rotated counterclockwise to allow the belt 272 to rotate through the transmission of the rotating shaft 271, thereby transporting the ring 274 to the inside of the frame 21 through the vertical plate 273;

[0048] When the rotating rod 261 rotates clockwise, the belt 272 will also rotate, but the ring 274 will start to move from the other side of the belt 272 and will not move into the frame 21. Since the length of the belt 272 is greater than the connecting rod 263, it will not have any effect.

[0049] Since the edge strips are made of cloth and are soft in texture, they will accumulate when entering the frame 21 . The conveying component 27 can prevent the edge strips from accumulating inside the frame 21 .

[0050] In further detail, one of the rotating shafts 271 is fixedly mounted on the rotating rod 261, and a groove is provided on the side of the frame 21 close to the belt 272. The arc block 275 is made of rubber, and several arc blocks 275 are equidistantly arranged. At this time, the vertical plate 273 will move to the inside of the frame 21 and start to move in the groove, thereby conveying the edging strip. The ring 274 will also be blocked by the arc block 275 when moving, and the ring 274 will rotate at this time, so there will be no impact.

[0051] Working principle: When in use, first install the hemming mechanism 20, install the mounting frame 251 on the sewing machine body 10 by screws, then place the moving frame 252 on the mounting frame 251, and adjust the positions of the frame 21, the lower guide frame 22 and the upper guide frame 23 by moving the moving frame 252, so that the lower guide frame 22 and the upper guide frame 23 correspond to the edge of the needle seat 11, and then fix the moving frame 252 and the mounting frame 251 together by screws;

[0052] By passing the edging strip through the support frame 276, the support frame 276 plays a guiding role and makes the edging strip flat. At this time, one end of the edging strip is passed through the ring 274, and the rotating rod 261 is rotated counterclockwise to make the belt 272 rotate through the transmission of the rotating shaft 271, and then the ring 274 is transported to the inside of the frame 21 through the vertical plate 273. At this time, the vertical plate 273 will move to the inside of the frame 21 and start to move in the groove, so that the edging strip is transported to the gap. At this time, the edging strip is manually pulled and passed through the angle between the lower guide frame 22 and the upper guide frame 23, and the ring 274 is moved out from the inside of the frame 21;

[0053] At this time, the combat boot tongue is placed on the placement rack 24 so that the edge of the combat boot tongue is located in the hemming strip, and the combat boot tongue is sewn together with the hemming strip by the needle seat 11 and the machine needle 12, thereby completing the hemming of the combat boot tongue;

[0054] When it is necessary to use hemming strips of different thicknesses to hem the tongue of combat boots, the distance between the required angles needs to be changed. By rotating the rotating rod 261 clockwise, the bearing drives the ratchet 262 to rotate as a whole. At this time, through meshing and the transmission of the synchronous belt 265, the two gears 264 will also rotate synchronously with the ratchet 262. The connecting rod 263 will also rotate through the gear 264, so that the upper guide frame 23 rises through the reciprocating thread groove 266, thereby changing the angle distance between the upper guide frame 23 and the lower guide frame 22;

[0055] Through the continuous rotation of the connecting rod 263, the upper guide frame 23 will descend after rising to the top through the reciprocating thread groove 266, realizing reciprocating motion to change the angular distance.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
