[0035] The features and performance of the folding guide with steering function of the application are further described in detail below in conjunction with the embodiments.

[0036] As Figure 2 , Figure 3 andFigure 4 As shown in the drawings, the embodiment of the present application provides a folding guide with a turning function, which comprises an L-shaped guide support 100, a cylindrical guide body 200 and a retaining ring 300; one end of the guide support 100 is provided with a guide hole 110 penetrating through both sides thereof, and the other end is connected to a sewing machine table through two bolts 120 penetrating through the top and bottom thereof; the guide body 200 is rotatably penetrated through the guide hole 110; the end surface of the guide body 200 is provided with a folding groove 210 penetrating through both ends thereof, and the cross section of the folding groove 210 is C-shaped for the pulling belt 400 to penetrate through.

[0037] In the embodiment, the two sides of both ends of the guide body 200 are recessed to form clamping flat heads 240; the outer wall of one end of the guide body 200 near the corresponding clamping flat head 240 is protruded to form an annular flange 220; the flange 220 is used to abut against the side wall of the guide support 100 to limit the axial movement of the guide body 200 when the guide body 200 penetrates through the guide hole 110; the other end of the guide body 200 near the corresponding clamping flat head 240 is recessed to form a clamping groove 230; the retaining ring 300 is provided with an opening 310 for being sleeved in the clamping groove 230 of the outer wall of the guide body 200; the inner wall of the opening 310 of the retaining ring 300 is recessed to form two grooves 320; when the retaining ring 300 is clamped in the clamping groove 230, the flange 220 is matched to limit the axial movement of the guide body 200 out of the guide hole 110.

[0038] When the folding guide with a turning function provided by the embodiment of the present application is installed on a sewing machine, first, two bolts 120 are used to connect one end of the guide support 100 to one side of the sewing machine presser foot 600 on the sewing machine table for feeding the cloth, and one end of the guide body 200 is penetrated through the guide hole 110 of the other end of the guide support 100; then, the retaining ring 300 is clamped in the clamping groove 230 of one end of the guide body 200 through the opening 310, so that the retaining ring 300 and the flange 220 protruded from the outer wall of the other end of the guide body 200 abut against the two sides of the guide support 100 respectively to limit the axial position of the guide body 200, so that the guide body 200 is rotatably penetrated through the guide hole 110 while being connected to the guide support 100 and not out of the guide hole 110.

[0039] When the folding guide with a turning function provided by the embodiment of the present application is used, as shown in the drawings, the cloth 500 to be sewn is placed below the sewing machine presser foot 600 on the sewing machine table, and the pulling belt 400 is folded and then penetrated through the folding groove 210 of the guide body 200 to be folded and stacked on the cloth 500, so that the folded pulling belt 400 and the cloth 500 can be sewn together; when one side of the cloth 500 and the folded pulling belt 400 are sewn together, as shown in the drawings, Figure 5 Figure 6 and Figure 7 ​As shown, the cloth 500 and the folded pull tape 400 are synchronously rotated, and the guide body 200 is rotated by 180 degrees, so that the other side of the cloth 500 is parallel to the feeding direction of the pull tape 400, the folded pull tape 400 is folded to be aligned with the other side of the cloth 500, and the pull tape 400 is sewn with the other side of the cloth 500 according to the previous sewing method. Similarly, the pull tape 400 is folded and sewn on each side of the cloth 500 by turning and sewing at the turning position.

[0040] The two ends of the guide body 200 are recessed to form clamping flat heads 240, which can be conveniently held by a user to rotate or fix the clamping flat heads 240, so as to facilitate the user to assemble or disassemble the guide body 200 or adjust the angle of the guide body 200. The inner wall of the opening 310 of the retainer ring 300 is recessed to form two grooves 320, which can improve the deformation performance of the retainer ring 300, and facilitate the user to connect or disassemble the retainer ring 300 in the clamping groove 230 of the outer wall of the guide body 200 through the opening 310.

[0041] The flange 220 protruding from the outer wall of one end of the guide body 200 can abut against one side wall of the guide support 100 to limit the position when the guide body 200 passes through the guide hole 110. When the retainer ring 300 is connected in the clamping groove 230 of the other end of the guide body 200 through the opening 310, the retainer ring 300 abuts against the other side wall of the guide support 100 to limit the position, so that the guide body 200 is axially limited and rotatably connected in the guide hole 110 of the guide support 100 through the flange 220 and the retainer ring 300. At this time, the guide body 200 is rotatably arranged in the guide hole 110. When it is necessary to disassemble the guide body 200, the guide body 200 can be moved axially to disengage from the guide hole 110 of the guide support 100 by separating the retainer ring 300 from the guide body 200.

[0042] The folding guide with the turning function provided by the embodiment can automatically fold the pull tape 400 through the guide body 200, so that the operation step of manually folding the pull tape 400 is saved, the folding standard of the pull tape 400 is improved, the complexity and difficulty of the operation of the worker are reduced, the sewing quality of the product is improved, the qualified rate of the product is improved by 59%, the production efficiency is directly doubled, and the economic benefit is effectively improved.

[0043] In other optional embodiments, the guide support 100 can be connected to the sewing machine table through one or more than three bolts 120.

[0044] In other optional embodiments, the guide support 100 can be detachably connected to the sewing machine table through buckles, adhesives or other connection structures.

[0045] In other optional embodiments, the number of grooves 320 formed by the inward recess of the inner wall of the opening 310 of the check ring 300 can also be one or more than three.

[0046] The embodiment of the present application also provides a sewing machine, which comprises a sewing machine table and the folding guide with the turning function.

[0047] The above-described embodiments are part of the embodiments of the present application, rather than all the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
