Description

Technical Field

[0001] This invention relates to the field of textile machinery and equipment technology, and in particular to a sewing machine, its sewing presser foot, and sewing method. Background Technology

[0002] In the process of sewing the sleeves of a shirt, when the fabric is wrinkle-free or thin, the sewn sleeve rings are prone to wrinkling, affecting product quality. Summary of the Invention

[0003] Therefore, it is necessary to provide a sewing device, its sewing presser foot, and its sewing method to solve the problem of wrinkling during sewing.

[0004] A sewing presser foot for use on sewing equipment includes a mounting mechanism, a pressing mechanism, and a rolling wheel;

[0005] The mounting mechanism is connected to the pressing mechanism. The mounting mechanism is used to connect to the sewing machine head of the sewing equipment. The pressing mechanism is used to press down the workpiece to be sewn. The pressing mechanism has a first side and a second side opposite to the first side. The second side is provided with a rib groove. The extending direction of the rib groove is the same as the feeding direction of the presser foot mechanism. The pressing mechanism is provided with a feeding clearance hole. The feeding clearance hole extends from the first side to the rib groove. The rolling wheel is disposed on the pressing mechanism. The rolling wheel is embedded in the feeding clearance hole and the wheel surface extends into the rib groove.

[0006] The inventors of this invention discovered that, due to the relatively thick rib area, the bottom of the presser foot of the flat presser foot experiences significant friction with the fabric, causing the sewn gusset to wrinkle easily. However, insufficient friction can affect fabric feeding. The aforementioned sewing presser foot features a rib groove on the second side of the pressing mechanism, the side used to press down the fabric. This groove secures the rib of the workpiece to be sewn while reducing friction with the fabric. A rolling wheel is embedded in the feed clearance hole, with its surface extending into the rib groove. During sewing, the rolling wheel propels the fabric forward across the fabric surface, reducing the pressure on the presser foot while maintaining fabric feeding, preventing fabric from accumulating and hindering further movement, and reducing wrinkling.

[0007] In one embodiment, the feed end of the pressing mechanism is curved upward to form a guide portion, and the sewing presser foot also includes a side-mounting mechanism. The side-mounting mechanism is disposed on the pressing mechanism and protrudes from the second side of the guide portion. The side-mounting mechanism is located on one side of the bone groove, and one side surface of the side-mounting mechanism is flush with one side wall of the bone groove.

[0008] The sewing presser foot in the above embodiment has a side-positioning mechanism on the pressing mechanism. The side-positioning mechanism is located on one side of the rib groove, and one side surface of the side-positioning mechanism is flush with one side wall of the rib groove. This can restrict the rib position of the fabric edge during feeding, reduce the difficulty of rib alignment, and avoid sewing misalignment.

[0009] In one embodiment, the side of the adjacent mechanism away from the guide portion is a convex arc surface.

[0010] In the above embodiment, the side of the guide portion of the sewing presser foot away from the pressing mechanism is set as a convex arc surface, which can guide the workpiece to be sewn, so that the workpiece to be sewn can smoothly enter the lower part of the pressing plate and improve the smoothness of the feeding of the workpiece to be sewn.

[0011] In one embodiment, the adjacent mechanism is detachably connected to the pressing mechanism, and the adjacent mechanism can be installed or removed as needed.

[0016] In one embodiment, the pressing mechanism is further provided with a needle relief hole, which extends from the first side to the bone groove.

[0017] In one embodiment, the needle relief hole is located between the feed end of the pressing mechanism and the feeding relief hole.

[0018] In one embodiment, the surface of the rolling wheel is provided with an anti-slip structure. The anti-slip structure may be anti-slip teeth, anti-slip protrusions, etc.

The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] This invention provides a sewing presser foot for use on sewing equipment. Using this sewing presser foot can reduce wrinkling of the sewing ring.

[0032] Please refer to Figure 1 and Figure 2 As shown, a sewing presser foot 100 according to an embodiment of the present invention includes an installation mechanism 110, a material pressing mechanism 120, and a rolling wheel 130.

[0033] The mounting mechanism 110 is connected to the pressing mechanism 120. The mounting mechanism 110 is used to connect to the sewing machine head of the sewing equipment.

[0034] The pressing mechanism 120 is used to press down the workpiece to be sewn. The pressing mechanism 120 has a first side 121 and a second side 122 opposite to the first side 121. The second side 122 is provided with a guide groove 123, the extension direction of which is the same as the feeding direction of the presser foot mechanism. The pressing mechanism 120 is provided with a feeding clearance hole, which extends from the first side 121 to the guide groove 123. The pressing mechanism 120 has a feeding end and a discharging end opposite to the feeding end, and the guide groove 123 extends from the feeding end to the discharging end.

[0035] Roller 130 is mounted on the pressing mechanism 120. Roller 130 is embedded in the feed clearance hole and its surface extends into the rib groove 123. The axial direction of roller 130 is perpendicular to the extension direction of rib groove 123. During sewing, roller 130 drives the fabric forward on the fabric surface, which reduces the pressure of presser foot 100 while maintaining the forward feed of fabric.

[0036] The inventors of this invention discovered that, due to the relatively thick rib area, the bottom of the presser foot of the flat presser foot experiences significant friction with the fabric, causing the sewn gusset to wrinkle easily. However, insufficient friction can affect fabric feeding. The aforementioned sewing presser foot 100 has a rib groove 123 on its second side 122 of the pressing mechanism 120, which is the side used to press down the fabric. The rib groove 123 is used to hold the rib of the workpiece to be sewn, while simultaneously reducing friction with the fabric. A rolling wheel 130 is embedded in the feed clearance hole, and its surface extends into the rib groove 123. During sewing, the rolling wheel 130 propels the fabric forward on the fabric surface, reducing the pressure on the sewing presser foot 100 while maintaining fabric feeding, preventing fabric from piling up and hindering progress, and reducing wrinkling.

[0037] like Figure 1 As shown, in one example, the feed end of the pressing mechanism 120 curves upward to form a guide portion 125. More specifically, in Figure 1 In the specific example shown, the pressing mechanism 120 includes a pressing plate portion 124 and a guide portion 125. The pressing plate portion 124 is generally flat and is used to press down the workpiece to be sewn. The guide portion 125 is at a certain angle to the pressing plate portion 124. The included angle between the guide portion 125 and the pressing plate portion 124 is an obtuse angle, which is used to guide the workpiece to be sewn so that the workpiece to be sewn can smoothly enter under the pressing plate portion 124.

[0038] In one example, the second side 122 of the pressure mechanism 120 is an arc surface at the connection between the pressure plate portion 124 and the guide portion 125.

[0039] In the example above, the second side 122 of the pressing foot 100 and the material pressing mechanism 120 is set as an arc surface at the connection between the pressing plate part 124 and the guide part 125, which can improve the smoothness of feeding of the workpiece to be sewn.

[0040] like Figure 1 As shown, in one example, the sewing presser foot 100 also includes a side mechanism 140, which is disposed on the pressing mechanism 120 and protrudes from the second side 122 of the guide portion 125. The side mechanism 140 is located on one side of the bone groove 123, and one side surface of the side mechanism 140 is flush with one side wall of the bone groove 123.

[0041] In the example above, the sewing presser foot 100 has a side-mounting mechanism 140 on the pressing mechanism 120. The side-mounting mechanism 140 is located on one side of the rib groove 123, and one side surface of the side-mounting mechanism 140 is flush with one side wall of the rib groove 123. This can restrict the rib position of the fabric edge during feeding, reduce the difficulty of rib alignment, and avoid sewing misalignment.

[0044] In one example, the adjacent mechanism 140 is detachably connected to the pressing mechanism 120, and the adjacent mechanism 140 can be installed or removed as needed. It is understood that in other examples, the adjacent mechanism 140 may also be non-detachably connected to the pressing mechanism 120, such as the adjacent mechanism 140 and the pressing mechanism 120 being integrally formed.

[0047] More specifically, the mounting part 126 includes a first mounting block 1261, a second mounting block 1262, and a third mounting block 1263 respectively connected to the first side 121 of the pressing mechanism 120. Each of the first mounting block 1261, the second mounting block 1262, and the third mounting block 1263 has a first mounting hole. The adjacent mechanism 140 has a second mounting hole. The mounting groove 111 of the mounting mechanism 110 has third mounting holes on both sides of its groove wall.

Between the second mounting block 1262 and the third mounting block 1263, the mounting shaft 150 sequentially passes through the third mounting hole on one side of the mounting groove 111, the first mounting hole of the first mounting block 1261, the axle hole of the rolling wheel 130, the first mounting hole of the second mounting block 1262, the second mounting hole of the adjacent mechanism 140, the first mounting hole of the third mounting block 1263, and the third mounting hole on the other side of the mounting groove 111, to connect and install the mounting mechanism 110, the pressing mechanism 120, the rolling wheel 130, and the adjacent mechanism 140. Further explanation: the first mounting block 1261, the second mounting block 1262, and the third mounting block 1263 can be separately installed or directly connected to form an integrated structure.

More specifically, the needle relief hole 127 is provided in the pressing plate portion 124 and extends from the first side 121 to the rib groove 123. The sewing needle of the sewing equipment can pass through the needle relief hole 127 to sew the fabric below the pressing mechanism 120.
