[0025] The following further describes the present utility model in detail in conjunction with embodiments, but the protection scope of the present utility model is not limited thereto.

[0026] The present utility model relates to a sewing machine assembly for installing a decorative strip at one time. The assembly includes a passing space 2 for fitting the decorative strip 1; the assembly is detachably cooperated with the presser foot 3 of the sewing machine.

[0027] In the present utility model, in fact, a channel for shaping is provided at the bottom of the small bottom 31 of the high and low presser feet 3 of the sewing machine, so that the decorative strip 1 can be limited within a certain passing space 2, especially for limiting both sides of the decorative strip 1, so that during the working process of the sewing machine, the relative position between the decorative strip 1 and the cloth surface it matches remains unchanged, and thus the operations of curling the edge and installing the decorative strip 1 can be realized.

[0028] In the present utility model, the shaping channel is the aforementioned passing space 2 for the decorative strip. In order to make this assembly match more application requirements, this passing space 2 needs to be adjustable. Further, the assembly and the presser foot 3 of the sewing machine are detachable.

[0029] It should be noted that in the present utility model, the names of the small bottom 31 of the presser foot and the presser foot edge 32 come from the Chinese patent "A Computer Tangent Flat Sewing Machine Anti-Nest Device" with the publication number CN204185662U. In the actual working environment, some technicians also call them high feet and low feet. The parts of the presser foot 3 corresponding to the two names are the same, which are easily understood by those skilled in the art.

[0030] The assembly includes a lower piece 4 and an adjusting piece 5 connected in sequence. The adjusting piece 5 includes an adjustable upper piece 51 and an adjustable lower piece 52. The lower piece 4 and the adjustable lower piece 52 are correspondingly arranged below the two end parts of the adjustable upper piece 51. A passing space 2 is provided between the lower piece 4 and the adjustable lower piece 52 and the adjustable upper piece 51.

[0031] The length of the adjustable upper piece 51 is greater than or equal to the width of the decorative strip 1.

[0032] An opening 6 is provided between the lower piece 4 and the adjustable lower piece 52.

[0033] The connection part of the lower piece 4 and the adjustable upper piece 51 is fixed and arranged towards the presser foot edge 32 of the presser foot 3 of the sewing machine.

[0034] In the present utility model, to be precise, the component is a slender metal sheet, which has a certain plasticity and avoids burrs that may damage the fabric. The components are successively a lower sheet 4, an adjustable upper sheet 51, and an adjustable lower sheet 52. The adjustable upper sheet 51 and the adjustable lower sheet 52 are collectively referred to as an adjusting sheet 5. The lengths of the adjustable upper sheet 51 and the adjustable lower sheet 52 are not unique, but the sum of their lengths is unique. Specifically, in the working state, the adjustable upper sheet 51 is located above the decorative strip 1, and the lower sheet 4 and the adjustable lower sheet 52 are located below the decorative strip 1. The distances between the adjustable upper sheet 51 and the lower sheet 4 and between the adjustable upper sheet 51 and the adjustable lower sheet 52 are not zero, forming a passing space 2.

[0035] In the present utility model, the significance of the adjusting sheet 5 is that by adjusting the lengths of the adjustable upper sheet 51 and the adjustable lower sheet 52, the length of the adjustable upper sheet 51 can be made greater than or equal to the width of the decorative strip 1, and as long as the diameter of the opening 6 between the lower sheet 4 and the adjustable lower sheet 52 is not greater than the width of the decorative strip 1, normal sewing operations can be ensured.

[0036] In the present utility model, for anti-fooling, it can be specified that the connection between the lower sheet 4 and the adjustable upper sheet 51 is fixed and is arranged towards the presser foot edge 32 of the presser foot 3 of the sewing machine. That is to say, defining the width of the lower sheet 4 as d1 and the total length of the adjustable upper sheet 51 and the adjustable lower sheet 52 as D, when the width of the decorative strip 1 is d2, the length of the adjustable lower sheet 52 is less than or equal to D - d2. If the diameter of the opening 6 after adjustment is greater than d2, other suitable components need to be replaced.

[0037] The component is connected to the presser foot bottom 31 of the presser foot 3 of the sewing machine through a connecting piece.

[0038] In the present utility model, the component needs to be detachably connected to the presser foot bottom 31 of the presser foot 3 of the sewing machine through a connecting piece. To increase the universality of the connecting piece, the position of the connecting piece is arranged close to the connection between the lower sheet 4 and the adjustable upper sheet 51. There are at least two implementation manners here.

[0039] Implementation manner 1

[0040] The connecting piece is a connecting piece 7 with one end arranged on the top surface of the adjustable upper sheet 51. The other end of the connecting piece 7 is arranged on the top of the presser foot bottom 31, and the top surface of the adjustable upper sheet 51 is arranged at the bottom of the presser foot bottom 31.

[0041] In this implementation manner, considering that the thickness of the component should not be too large, otherwise it will affect the actual operation, the connecting piece is in the form of the connecting piece 7. One end of it is connected to the top surface of the adjustable upper sheet 51. During the process, the top surface of the adjustable upper sheet 51 is attached to the bottom of the presser foot bottom 31, and then the other end of the connecting piece 7 is connected to the top of the presser foot bottom 31. It is equivalent to setting a foldable elastic sheet on the top of the component, which can be buckled at the presser foot bottom 31 of the presser foot 3 based on the certain strength and elasticity of the metal itself.

[0042] In this embodiment, in order to ensure the connection of the connecting member, the folded end of this connecting member is arranged towards the small bottom 31 side of the presser foot 3, and generally, the setting direction of the connecting piece is the same as the conveying direction of the decorative strip 1, that is, during the process of feeding the decorative strip 1 into the assembly for sewing, the adjustable upper piece 51 and the small bottom 31 of the presser foot are always fitted by the connecting member, and there is no risk of falling; if there is still uncertainty, this connecting piece 7 can be attached to the presser foot 3 through a detachable adhesive, such as dotting glue, tape, etc.

[0043] Embodiment 2

[0044] The connecting member is a connecting ring 8 provided on the top surface of the adjustable upper piece 51, and the connecting ring 8 is sleeved outside the small bottom 31 of the presser foot.

[0045] In this embodiment, a connecting ring 8 is directly provided on the top of the connecting member and sleeved outside the small bottom 31 of the presser foot 3. Generally, the small bottom 31 of the presser foot 3 is not of equal width, so the inner diameter of the connecting ring 8 can be set to make it stuck at a certain position of the small bottom 31 of the presser foot 3. Similarly, after reaching this position, during the process of feeding the decorative strip 1 into the assembly for sewing, the connecting ring 3 always holds this position, and then the adjustable upper piece 51 and the small bottom 31 of the presser foot cooperate, and there is no risk of falling.

[0046] The width of the assembly is less than 1 cm.

[0047] The thickness of the assembly is less than 0.05 cm.

[0048] In the present utility model, the existence of the assembly should not affect the actual sewing operation, so the thickness should be small, and the width should not be so large as to affect the entry and exit of the decorative strip 1, but its width should at least be able to play a role in restricting the position of the decorative strip 1; generally, the thickness of the assembly is 0.02 cm and the width is 0.5 - 0.8 cm.

[0049] In the present utility model, the projection of the assembly on the vertical plane can also be set with a horizontal part, a transition part and a slope part, that is, the slope part faces the direction in which the decorative strip 1 is fed, which is convenient for the input of the decorative strip 1. After passing through the transition part, it is flattened by the horizontal part to realize the sewing connection with the bottom fabric.

[0050] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
