DETAILED DESCRIPTION​​​​

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0031] With reference to Figures 1-6 A single needle sewing machine feed direction correction device, including clothing processing table 1, clothing processing table 1 bottom fixedly installed with supporting leg 2, clothing processing table 1 top fixedly installed with machine base 3, machine base 3 top installed with single needle sewing machine 4, single needle sewing machine 4 outside provided with feed direction correction mechanism 6;Feed direction correction mechanism 6 includes installation bottom plate 61, installation bottom plate 61 side screw joint installation has bending side plate 62, installation bottom plate 61 and bending side plate 62 top are sequentially installed with first guide wheel 65, second guide wheel 66 and third guide wheel 67, installation bottom plate 61 top side is provided with installation slot 610, installation slot 610 inner side center position fixedly installed with fixed column 612, fixed column 612 top side is provided with sliding slot 616, sliding slot 616 bottom fixedly installed with electromagnetic coil 617, sliding slot 616 inner side slidingly installed with sliding column 618, sliding column 618 bottom fixedly installed with permanent magnet 619, permanent magnet 619 and electromagnetic coil 617 between installation has plastic spring 620, plastic spring 620 bottom is not connected with electromagnetic coil 617, sliding column 618 top fixedly installed with abutting top cover 621, installation slot 610 inner side fixedly installed with backing plate 611, single needle sewing machine 4 side wall top fixedly installed with controller 5.

[0032] Through the above structure, the bottom of the plastic spring 620 is not connected with the electromagnetic coil 617, and then the sliding column 618, the permanent magnet 619 and the plastic spring 620 below are driven out of the sliding slot 616 by holding the abutting top cover 621, so that the thread drum 68 is placed from the top of the fixed column 612 to the outside of the fixed column 612. The main function of the plastic spring 620 here is to overcome the self-weight effect of the abutting top cover 621, the sliding column 618 and the permanent magnet 619, to lift the abutting top cover 621, so that the abutting top cover 621 does not abut the upper end of the thread drum 68 below.

[0033] In this embodiment, the fixed column 612 is provided with a thread drum 68 outside, the thread drum 68 is wound with a knitting thread 69, and the knitting thread is sequentially wound through the first guide wheel 65, the second guide wheel 66 and the third guide wheel 67.

[0034] Through the above structure, the first guide wheel 65, the second guide wheel 66 and the third guide wheel 67 are provided, which provides the function of direction correction of the incoming thread for the knitting thread 69 entering the output end of the single needle sewing machine 4, preventing the incoming thread from winding.

[0035] In this embodiment, the mounting bottom plate 61 and the bent side plate 62 are screwed and mounted on the outer side wall of the single needle sewing machine 4.

[0036] Through the above structure, the mounting bottom plate 61 and the bent side plate 62 are screwed and mounted on the outer side wall of the single needle sewing machine 4, which facilitates the disassembly and maintenance work in the later period.

[0037] In this embodiment, the bent side plate 62 is provided with a hole groove 63 at the bottom, and the output end of the single needle sewing machine 4 passes through to the lower side of the hole groove 63. In this embodiment, the bent side plate 62 is provided with assembly screws 64 at the side edges.

[0038] Through the above structure, the bent side plate 62 is screwed and mounted on the side edge of the mounting bottom plate 61 through the assembly screws 64. First, the bent side plate 62 is detached from the side edge of the mounting bottom plate 61, the screw positioning of the bent side plate 62 and the outer wall of the single needle sewing machine 4 is released, and then the bent side plate 62 is pulled out from the lower side of the single needle sewing machine 4.

[0039] In this embodiment, a limiting strip is fixedly connected to the side wall of the slide column 618, and a limiting groove matched with the limiting strip is formed in the inner side of the sliding groove 616.

[0040] Through the above structure, the limiting strip and the limiting groove are arranged to limit the rotational freedom of the slide column 618 in the inner side of the sliding groove 616, so that the abutting top cover 621 and the fixed column 612 do not have rotational freedom, and when the abutting top cover 621 abuts on the upper end of the stranding drum 68, the rotation of the stranding drum 68 can be limited by the friction between the abutting top cover 621 and the upper end of the stranding drum 68.

[0041] In this embodiment, a plurality of telescopic cylinders 613 are fixedly installed on the outer wall of the fixed column 612, a roller 614 is rotatably installed at the outer side end of the telescopic cylinder 613, a spring 615 is installed in the inner side of the telescopic cylinder 613, and the outer side of the roller 614 abuts against the inner wall of the stranding drum 68. The spring 615 is a compressed durable spring.

[0042] Through the above structure, the roller 614 abuts against the inner wall of the stranding drum 68, and the rotational freedom of the roller 614 allows the stranding drum 68 to rotate flexibly outside the fixed column 612. In addition, the distance between the roller 614 and the fixed column 612 utilizes the deformation freedom of the spring 615, so that the distance between the roller 614 and the fixed column 612 has a certain variable driving, which can be applied to different specifications of the stranding drum 68 rotating and being sleeved outside the fixed column 612, thereby improving the application range.

[0043] The utility model discloses a single needle sewing machine 4 drives knitting thread 69 to carry out sewing work on the output end when working, and at the same time, generates downward pulling force to knitting thread 69, makes the twisting drum 68 self-rotates and releases knitting thread 69, and knitting thread 69 is sequentially conveyed to the output end of single needle sewing machine 4 through first guide wheel 65, second guide wheel 66 and third guide wheel 67, when single needle sewing machine 4 stops working, the controller 5 controls the energization of the electromagnetic coil 617 at this time, and the magnetic attraction between the electromagnetic coil 617 and the permanent magnet 619 presses the contact top cover 621 on the upper end of the twisting drum 68, and the friction between the contact top cover 621 and the twisting drum 68 can make the twisting drum 68 stop self-rotation immediately due to inertia, and further make the twisting drum 68 stop immediately when single needle sewing machine 4 stops working, prevent loosening in the threading line, and further avoid the disadvantages of winding.
