[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The semi-automatic folding and sewing single-piece hem machine is provided with an air blowing round tube to move the cloth to the sensing point of the induction electric eye. The cloth passes through the lower part of the feeding plate and then passes through the gap between the air blowing baffle and the feeding plate to the upper wall of the feeding plate. The control system of the sewing machine controls the air to be pressed into the inside of the air blowing round tube and then blown out from the air blowing hole. At this time, the air blowing hole is located at the rear side of the cloth. After the air is blown out from the air blowing hole, the cloth is automatically folded on the upper wall of the feeding plate, thereby achieving an automatic folding effect.

[0013] (2) The semi-automatic folding single-piece hem machine is provided with a roller. When the cloth moves to the sensing point of the induction electric eye, the induction electric eye is delayed to press on the cloth to fix the cloth, and then the tug switch is turned on. The tug switch starts the tug, and the motor inside the tug starts to drive the rotating shaft. The motor shaft drives the synchronous wheel to rotate. The synchronous wheel drives the roller to rotate through the synchronous belt. At this time, the tug telescopic rod moves downward and the synchronous belt protective cover moves downward. The synchronous belt protective cover drives the roller to move downward synchronously. When the outer cylinder of the roller is pressed on the cloth, the rotating roller drives the cloth to move horizontally to the left, thereby avoiding the situation that the cloth is manually pulled by the sewing machine and the cloth is sewn non-parallel.

[0014] (3) The semi-automatic folding single-piece hem machine is provided with a roller. When the cloth moves to the sensing point of the induction electric eye, the induction electric eye is delayed to press on the cloth to fix the cloth, and then the tug switch is turned on. The tug switch starts the tug, and the motor inside the tug starts to drive the rotating shaft. The motor shaft drives the synchronous wheel to rotate. The synchronous wheel drives the roller to rotate through the synchronous belt. At this time, the tug telescopic rod moves downward and the synchronous belt protective cover moves downward. The synchronous belt protective cover drives the roller to move downward synchronously. When the outer cylinder of the roller presses on the cloth, the rotating roller drives the cloth to move horizontally to the left. The roller automatically pulls the cloth to move, thereby realizing automated industrial production and improving production efficiency.

[0015] (4) The semi-automatic creased single-piece hem machine is provided with a pressing block. The cloth is placed on the top of the cover plate and the pressing block is pulled upward. The pressing block moves upward along the inclined surface in the inclined through hole of the front bracket ear. After the textile worker releases his hand, the pressing block automatically moves downward due to its own gravity. The pressing block moves downward in the inclined hole of the front bracket ear through the step screw and presses on the cloth, fixing the cloth above the cover plate. At this time, the presser foot fixes the cloth on the feeding flat workbench. The textile worker's arm touching the cloth on the cover plate will not cause the cloth to move, thereby avoiding the situation where the cloth is distorted and causes sewing to be tilted.

[0016] (5) The semi-automatic folding single-piece hem machine is provided with a slide, and the slide plate slides left and right in the groove of the slide. When the presser foot automatically presses the cloth, sewing is started through the control of the sewing machine system. When the tug wheel rotates at the same time to drive the cloth to move to the left, the cloth drives the pressing block to move to the left, the pressing block drives the cover plate to move to the left, the cover plate drives the sliding support plate to move to the left, and the sliding support plate drives the slide plate to move to the left in the groove of the slide. The cloth is moved synchronously on both sides, thereby avoiding the occurrence of uneven cloth when the cloth is sewn.

[0017] (6) The semi-automatic folding single-piece hem machine is provided with a blanking plate. The inclined plate of the blanking plate is gradually inclined from top to bottom and from right to left in the electric control box. When the tail end of the cloth is cut off, the cloth will slide directly to the bottom of the supporting table along the inclined plate of the blanking plate due to its own gravity, thereby avoiding the situation where the finished cloth on the left side is blocked after the cloth is automatically cut.

[0018] (7) The semi-automatic folding single-piece hem machine is provided with an induction electric eye. When the left side of the fabric is sewn and cut, the induction electric eye detects that there is still unprocessed fabric on the feeding plate. The induction electric eye sends a signal to the system, and the system controls the pressing block to reset to the starting position. The second piece of fabric is sewn repeatedly without manual grasping of the fabric. The sewing worker can operate both sides of the machine at the same time, which saves operating time and greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the air blowing hole 13 is located on the rear side of the cloth. After the air is blown out from the air blowing hole 13, the cloth is automatically folded on the upper wall of the feeding plate 8.

[0037] By providing the roller 20, when the cloth moves to the sensing point of the induction electric eye 30, the induction electric eye 30 delays and presses on the cloth to fix the cloth, and then the tug switch 16 is turned on, the tug switch 16 starts the tug 15, the motor inside the tug 15 starts to drive the rotating shaft, the motor rotating shaft drives the synchronous wheel 19 to rotate, the synchronous wheel 19 drives the roller 20 to rotate through the synchronous belt 21, at this time the tug telescopic rod 17 moves downward with the synchronous belt protective cover 22 to move downward, the synchronous belt protective cover 22 drives the roller 20 to move downward synchronously, when the outer cylinder of the roller 20 is pressed on the cloth, the rotating roller 20 drives the cloth to move horizontally to the left, avoiding the situation that the cloth is manually pulled by the sewing machine and the cloth is not sewn parallel.

[0038] By providing the roller 20, when the cloth moves to the sensing point of the induction electric eye 30, the induction electric eye 30 delays and presses on the cloth to fix the cloth, and then the tug switch 16 is turned on, the tug switch 16 starts the tug 15, the motor inside the tug 15 starts to drive the rotating shaft, the motor rotating shaft drives the synchronous wheel 19 to rotate, the synchronous wheel 19 drives the roller 20 to rotate through the synchronous belt 21, at this time the tug telescopic rod 17 moves downward with the synchronous belt protective cover 22 to move downward, the synchronous belt protective cover 22 drives the roller 20 to move downward synchronously, when the outer cylinder of the roller 20 presses on the cloth, the rotating roller 20 drives the cloth to move horizontally to the left, the roller 20 automatically pulls the cloth to move, realizes automated industrial production, and improves production efficiency.

[0039] By providing a pressing block 40, the cloth is placed above the cover plate 39, and the pressing block 40 is pulled to move upward. The pressing block 40 moves upward along the inclined surface in the inclined through hole of the front bracket ear 41. After the textile worker releases his hand, the pressing block 40 automatically moves downward due to its own gravity. The pressing block 40 moves downward in the inclined hole of the front bracket ear 41 through the step screw 42 and presses on the cloth, fixing the cloth above the cover plate 39. At this time, the presser foot 31 fixes the cloth on the feeding plate 8 workbench 7. The textile worker's arm touching the cloth on the cover plate 39 will not drive the cloth to move, thereby avoiding the situation where the cloth is distorted and causes sewing to be tilted.

[0040] By providing a slide 36, the slide plate 37 slides left and right in the groove of the slide 36. When the presser foot 31 automatically presses the cloth, sewing is started through the sewing machine system control. When the tug 15 rotates at the same time to drive the cloth to move to the left, the cloth drives the pressing block 40 to move to the left, the pressing block 40 drives the cover plate 39 to move to the left, the cover plate 39 drives the sliding support plate 38 to move to the left, and the sliding support plate 38 drives the slide plate 37 to move to the left in the groove of the slide 36. The cloth is moved synchronously on both sides, thereby avoiding the occurrence of uneven cloth when sewing cloth.

[0041] By providing a blanking plate 33, the inclined plate of the blanking plate 33 of the electric control box 3 is gradually inclined from top to bottom and from right to left. When the tail end of the cloth is cut off, the cloth will slide directly to the bottom of the support table 1 along the inclined plate of the blanking plate 33 due to its own gravity, avoiding the situation where the finished cloth on the left side is blocked after automatic cutting of the cloth.

[0042] By providing the induction electric eye 30, when the left side of the cloth is cut after being sewn, the induction electric eye 30 detects that there is still unprocessed cloth on the feeding plate 8, and the induction electric eye 30 sends a signal to the system, and the system controls the pressing block 40 to reset to the starting position, and the second piece of cloth is repeatedly sewn without manual grasping of the cloth. The sewing worker can operate the machines on both sides at the same time, which saves the operating time and greatly improves the work efficiency.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
