[0016] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0017] Figures 1 to 4 is a schematic diagram of the structure of the embodiment of the present application.

[0018] The figure marks are as follows: first roller 1, spiral feeding guide groove 11, roller mounting seat 12, first motor 13, seam inductor 15, seam inductor 16, second roller 2, upper clamp plate 31, lower clamp plate 32, trademark position inductor 41, inductor mounting seat 42, trademark position sensor 43, feeding guide rail 51, poking rod 52, pulling device 53, pulling cylinder 531, clamping device 54, conveying poking piece 55, folding plate 6, folding driving cylinder 61, mounting bracket 7, grabbing arm 71, grabbing cylinder 72, grabbing clamp 73, first synchronous wheel 74, feeding motor 75, second synchronous wheel 76, synchronous belt 77.

[0019] The collar sewing machine has a sewing head fixedly installed on a frame, and generally adopts a collar sewing head. A rotary feeding device is arranged in front of the sewing head, and a shirt and a collar are arranged on the rotary feeding device. The rotary feeding device drives the shirt and the collar to rotate, and sends a sewing path to the sewing position of the collar sewing head. A collar trademark feeding device is also arranged on the frame, and a cut and folded collar trademark is sent to the sewing path between the shirt layer and the collar layer, so that the collar trademark is sewn and fixed during the sewing of the shirt and the collar.

[0020] The rotary feeding device comprises a first roller 1 and a second roller 2 for feeding. A blowing pipe for blowing is arranged between the first roller 1 and the second roller 2, which can assist the rotary feeding of the shirt layer and the collar layer.

[0021] A deviation rectifying mechanism is arranged between the first roller 1 and the second roller 2. The deviation rectifying mechanism comprises an upper clamp plate 31 and a lower clamp plate 32 for clamping the material. The clamping surfaces of the upper clamp plate 31 and the lower clamp plate 32 are respectively provided with rotatable conveying belts. In order to control the edge alignment of the shirt layer and the collar layer and accurately sew along the sewing path, the upper clamp plate 31 and the lower clamp plate 32 of the deviation rectifying mechanism clamp the sewing material, and control the movement of the sewing material through the rotation of the conveying belts, so as to keep the sewing path of the sewing material.

[0022] The first roller 1 has a conical body, and a convex spiral feeding guide groove 11 is arranged on the conical body. The spiral feeding guide groove 11 is directed towards the direction of the sewing needle. In the rotary feeding process of the sewing material, the blowing airflow will apply an outward pushing force to the sewing material due to the assistance of the blowing pipe, which will cause large deviation rectifying resistance of the deviation rectifying mechanism and unsensitive deviation rectifying reaction. The convex spiral feeding guide groove 11 arranged on the first roller 1 can reduce the contact area between the sewing material and the first roller 1, thereby reducing the friction, and can balance the pushing force applied by the airflow through the feeding guide groove 11, so that the deviation rectifying mechanism can better rectify the sewing path and improve the sewing quality.

[0023] The first roller 1 is rotatably installed on a roller mounting base 12, and a first motor 13 is fixed to the rear of the roller mounting base 12, and the driving shaft of the first motor 13 is connected with the first roller 1.

[0024] A seam sensing piece 15 is arranged below the first roller 1, and the seam sensing piece 15 is rotatably installed on the roller mounting base 12, and one end of the seam sensing piece 15 is in contact with the material sleeved on the first roller 1 and the second roller 2, and the other end is coupled with a seam sensor 16.

[0025] The collar trademark feeding device comprises a collar trademark feeding mechanism, a collar trademark cutting mechanism and a collar trademark folding mechanism, and a movable trademark grabbing mechanism is arranged between the output port of the collar trademark folding mechanism and the collar trademark feeding position.

[0026] In the prior art, the identification of the collar trademark insertion position is a technical difficulty, because the collar trademark insertion position is a specific position fixed between the collar layer and the shirt layer, and the collar and the shirt are soft cloth and cannot be positioned.

[0027] The trademark position sensor of the present application comprises a trademark position sensing rod 41 located between the collar layer and the shirt layer, and the trademark position sensing rod 41 is rotatably installed on a sensor mounting base 42, and the tail end of the trademark position sensing rod 41 is coupled with a trademark position sensor 43 on the sensor mounting base 42. The trademark position sensing rod 41 is located in front of the needle sewing, and does not interfere with the sewing of the collar layer and the shirt layer. When the collar layer and the shirt layer are sewn close to one turn, the trademark position sensing rod 41 will be actuated because the sewing position of the collar layer and the shirt layer has been sewn together, thereby triggering the position recognition sensing.

[0028] The collar trademark feeding mechanism comprises a feeding guide rail 51, and the feeding guide rail 51 has multiple sections, and a material pushing rod 52 capable of moving up and down is arranged on the conveying path of the feeding guide rail 51. The collar trademark material is a rolled strip-shaped fabric material, and the strip-shaped material is conveyed along the feeding guide rail 51, and the strip-shaped material on the feeding guide rail 51 is pulled by the material pushing rod 52, so that the strip-shaped material leaves a surplus for subsequent pulling and folding.

[0029] The feeding guide rail 51 is provided with a conveying pushing piece 55, which can convey the strip-shaped material along the feeding guide rail 51 and prevent it from retreating.

[0030] The output end of the feeding guide rail 51 is provided with a pulling device 53 capable of moving linearly, and the output end is provided with a clamping device 54 capable of clamping the output material.

[0031] The pulling device 53 comprises a pulling clamp 532 for clamping the neckband label, and a pulling cylinder 531 for driving the pulling clamp 532 to move. The pulling clamp 532 clamps the front part of the belt-shaped material, and the pulling cylinder 531 drives the pulling clamp 532 to move downward so that the front end of the belt-shaped material moves to the clamping device 54. After the clamping device 54 clamps and fixes the front end of the belt-shaped material, the pulling cylinder 531 drives the pulling clamp 532 to retreat.

[0032] The pulling clamp 532 can be a one-way pawl arranged on the feeding channel of the pulling device 53. When the pulling clamp 532 retreats under the driving of the pulling cylinder 531, the belt-shaped material is pulled out of the pulling clamp 532.

[0033] The neckband label folding mechanism comprises a folding plate 6 moving linearly between the pulling device 53 and the clamping device 54, and a folding driving cylinder 61 for driving the folding plate 6 to move. In the embodiment, the folding plate 6 can move linearly horizontally against the pulled belt-shaped material to fold the belt-shaped material. The neckband label cutting mechanism comprises a cutting knife arranged above the folding plate 6, and a cutting cylinder for driving the cutting knife to move. The cutting cylinder can drive the cutting knife to cut the output belt-shaped material.

[0034] The clamping device 54 comprises a clamping cylinder and a clamping clamp driven by the clamping cylinder. After the clamping device 54 clamps and fixes the front end of the belt-shaped material, the belt-shaped material is pulled out for a certain length, then the folding driving cylinder 61 drives the folding plate 6 to move linearly horizontally, the folding plate 6 presses against the pulled belt-shaped material to fold it and clamps it by the label grabbing mechanism. Subsequently, the neckband label cutting mechanism cuts the belt-shaped material outside the pulling device 53, and the label grabbing mechanism sends the clamped label material to the position between the shirt layer and the round neck layer after detecting the insertion position by the label position sensor.

[0035] The label grabbing mechanism comprises a mounting bracket 7, one end of the mounting bracket 7 is provided with a rotatable grabbing arm 71, the movable end of the grabbing arm 71 is provided with a grabbing cylinder 72 and a grabbing clamp 73. The grabbing cylinder 72 can control the opening and closing of the grabbing clamp 73. The rotating end of the grabbing arm 71 is rotatably connected with the mounting bracket 7 and is connected with a first synchronous wheel 74. The other end of the mounting bracket 7 is provided with a feeding motor 75 and a second synchronous wheel 76, and the first synchronous wheel 74 and the second synchronous wheel 76 are connected by a synchronous belt 77. After the insertion position of the neckband label is recognized, the feeding motor 75 drives the first synchronous wheel 74 to rotate through the synchronous belt 77, the first synchronous wheel 74 drives the grabbing arm 71 to rotate, and the grabbing clamp 73 clamped neckband label moves to the upper label position between the shirt layer and the round neck layer.

[0036] The best embodiment of the present application has been illustrated, and various changes or modifications made by those skilled in the art will not deviate from the scope of the present application.
