DETAILED DESCRIPTION
[0032] The application will be further described in detail below with reference to the accompanying drawings.
[0033] The embodiment of the application discloses a zipper sewing guide used for a sewing machine presser foot, referring to Figure 1 and Figure 2 , comprising a base plate 1, an axle seat 2 and a pressing wheel 3, the axle seat 2 is fixed on the base plate 1, the pressing wheel 3 is rotationally connected on the axle seat 2, the base plate 1 is detachably connected on the sewing machine and located at one side of a sewing needle, when a user needs to sew a zipper on a cloth, the user pastes the zipper on the cloth and lays the zipper and the cloth on a workbench of the sewing machine, so that the length direction of the zipper is perpendicular to the length direction of a rotating shaft of the pressing wheel 3, the pressing wheel 3 is pressed on the zipper, at this time, the user moves the cloth and the zipper along a straight line, so that the sewing machine can sew the cloth and the zipper, the zipper can be kept at a predetermined position and sewn on the cloth during the sewing process, thereby reducing the probability that the zipper is skewed and sewn on the cloth, and thereby improving the working quality of the zipper sewing.
[0034] Referring to Figure 1 and Figure 2 , the mounting plate 11 is arranged on the base plate 1, the mounting groove 111 is arranged on the mounting plate 11, and the user sets a bolt in the mounting groove 111, so that the mounting plate 11 is detachably connected on the sewing machine.
[0035] Referring to Figure 1 and Figure 2 , a plurality of grooves 31 are arranged on the surface of the pressing wheel 3, the grooves 31 are equidistantly and spaced apart along the circumferential direction of the pressing wheel 3, the surface of the pressing wheel 3 is roughened by arranging the grooves 31, and thereby the surface friction between the pressing wheel 3 and the zipper is improved, so that the zipper can be kept flat and pass below the pressing wheel 3.
[0036] Referring to Figure 1 , Figure 2 and Figure 3The substrate 1 is provided with a pressing assembly 4, the pressing assembly 4 comprises a pressing plate 41, a mounting bolt 42 and a rotating shaft 43, the rotating shaft 43 penetrates the shaft seat 2 and the pressing wheel 3, the middle part of the pressing plate 41 is rotationally connected to the rotating shaft 43, one end of the pressing plate 41 is used for pressing on the zipper and the cloth, and the other end is connected to the mounting bolt 42. The pressing plate 41 is provided with a tension spring 5, one end of the tension spring 5 is mounted on the mounting bolt 42, and the other end is mounted on the substrate 1. The tension spring 5 is tensioned on one end of the pressing plate 41, so that the other end of the pressing plate 41 can always press on the zipper, thereby reducing the probability of position skewing of the zipper during the sewing process.
[0037] With reference to Figure 3 and Figure 4 The pressing plate 41 comprises two side plates 411 and a connecting plate 412, the two side plates 411 are respectively arranged on the two sides of the pressing wheel 3, the connecting plate 412 is connected to the end parts of the two side plates 411, and the mounting bolt 42 is mounted on the connecting plate 412. The two ends of the tension spring 5 are respectively fixedly connected with a hanging ring 51, the substrate 1 is provided with a hook 12, one end of the tension spring 5 is hung on the mounting bolt 42, and the other end is hung on the hook 12. The substrate 1 is provided with an adjusting bolt 6, the adjusting bolt 6 penetrates the substrate 1 and is threadedly connected with the substrate 1, and the adjusting bolt 6 is perpendicular to the substrate 1. The lower end of the adjusting bolt 6 is used for abutting against the pressing plate 41. In a natural state, the tension spring 5 is tensioned on one end of the pressing plate 41, so that the end part of the pressing plate 41 connected with the tension spring 5 abuts against the adjusting bolt 6. A user can move the adjusting bolt 6 by screwing the adjusting bolt 6, thereby controlling the position of the end part of the pressing plate 41 away from the tension spring 5. When the thickness of the cloth and the zipper pressed by the pressing plate 41 changes, the pressing plate 41 can always press on the cloth and the zipper.
[0038] With reference to Figure 3 and Figure 4 One end part of one side plate 411 is provided with a bottom plate 413, and the other end part of the other side plate 411 is provided with a cover plate 414. The bottom plate 413 and the cover plate 414 are arranged on the side of the side plate 411 away from the connecting plate 412. The cover plate 414 is arranged higher than the bottom plate 413. By inserting the zipper between the bottom plate 413 and the cover plate 414, the limiting effect on the zipper can be further improved. When the pressing plate 41 presses on the workbench of the sewing machine, the bottom plate 413 presses on the cloth, and the zipper is located between the bottom plate 413 and the cover plate 414.
[0039] With reference to Figure 3 and Figure 4 The lower part of the cover plate 414 is provided with a side baffle 415, the side baffle 415 is parallel to the side plate 411, and the side baffle 415 is used for clamping the side part of the zipper. When the zipper is arranged between the cover plate 414 and the bottom plate 413, the cover plate 414, the bottom plate 413, the side baffle 415 and the side plate 411 connected with the bottom plate 413 form a frame structure and frame the zipper, so that the probability of horizontal movement of the zipper can be reduced, and the positioning effect on the zipper can be improved.
[0040] Referring to Figure 4 The bottom of the side plate 411 on the left and right sides of the pressing wheel 3 is not flush, and the bottom of the side plate 411 connected with the cover plate 414 is higher than the bottom of the side plate 411 connected with the bottom plate 413. When the width of the zipper sewn on the cloth is greater than the distance between the two side plates 411, the side plate 411 connected with the cover plate 414 can be pressed on the zipper, so that the zipper with a larger size is arranged in the space between the side plate 411 and the side baffle 415, facilitating use.
[0041] Referring to Figure 4 The side of the pressing plate 41 abutting against the cloth is provided with a circular arc surface 416, which is used to eliminate the edges and corners of the bottom surface of the pressing plate 41, thereby reducing the probability of the pressing plate 41 scratching the cloth.
[0042] Referring to Figure 3 In other embodiments, the side plate 411 and the cover plate 414 are detachably connected, the cover plate 414 is provided with a plurality of bolts, the bolts penetrate through the cover plate 414 and are connected with the side plate 411, and a user can install cover plates 414 with different shapes on the side plate 411, so as to adjust the distance between the side baffle 415 and the side plate 411, and enable zippers with different widths to be installed at the end of the pressing plate 41.
[0043] The implementation principle of the embodiment of the application is that the pressing wheel 3 is rotatably connected on the base plate 1, so that the pressing wheel 3 can be pressed on the zipper, and then when the zipper is sewn, the zipper and the cloth can be kept in a flat state passing under the sewing needle, thereby improving the sewing quality. The pressing plate 41 is rotatably connected on the base plate 1, so that the pressing plate 41 is provided with pre-tightening force by the tension spring 5, and then the end of the pressing plate 41 away from the tension spring 5 can be pressed on the cloth, further reducing the probability of the cloth and the zipper slipping.
[0044] The above are preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made on the basis of the structure, shape, principle of the application should be covered within the protection scope of the application.
