Description

Technical Field

[0001] The utility model belongs to the technical field of sewing equipment and relates to a material fixing sheet and a material pressing device. Background Art

[0002] During the sewing process of the pocket fabric, the pocket fabric needs to be positioned, and a fixing sheet or a pressing mechanism is needed at this time. For the working principle of the fixing sheet and the pressing mechanism, you can refer to a pressing device disclosed in application number 202123037412.7.

[0003] In the prior art, the fixing sheet is usually a thin piece. Because it is relatively thin, it will be deformed after being used for a long time, especially the middle part will sag downward, and this part will be concave, resulting in the middle of the fixing sheet being able to press the fabric, but its two ends cannot press the fabric. In order to solve this problem, a gasket is usually added for support. The fixing sheet presses the pocket fabric, and the pocket fabric is pressed on the platform. The gasket is located between the pocket fabric and the platform, which increases the distance from the pocket fabric to the platform, making the gap larger. During the sewing process, the machine needle is prone to skipping stitches, affecting the quality of the sewing seams. Summary of the invention

[0004] The utility model aims at the above problems existing in the prior art and provides a fixing piece. The technical problem to be solved by the utility model is: how to prevent the fixing piece from being deformed.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A fixing sheet comprises a main board body, wherein one side of the main board body has a convex edge extending outwards, and the thickness of the main board body is greater than the thickness of the convex edge.

[0007] In the fixing sheet, the main plate body is relatively thick and is used for connecting and fixing with other parts, and the convex edge is relatively thin and is used for pressing the pocket fabric.

[0008] The main body of the fixing sheet is thicker, the overall strength of the fixing sheet is greater, and it is not easy to deform. No additional gasket is required when pressing the material. When in use, the convex edge of the fixing sheet can directly press the pocket fabric onto the platform, which not only solves the problem of easy deformation of the fixing sheet, but also solves the problem of gap between the pocket fabric and the platform. The convex edge of the fixing sheet directly presses the pocket fabric onto the platform, and the pocket fabric is directly fitted to the platform, which can prevent skipped stitches and make the sewn stitches more beautiful.

[0009] In the above-mentioned fixed material sheet, the width of the main board body is greater than the width of the protruding edge.

[0010] The width of the main board body is larger than the width of the convex edge, and the area of ​​the main board body is also larger than the area of ​​the convex edge. The main board body occupies more than half of the area. In the entire fixed material sheet, the thicker part (main board body) accounts for more than half. The fixed material sheet of this structure is stronger.

[0011] In the above-mentioned fixed material sheet, the width of the main board body is 2-5 times the width of the convex edge.

[0012] The width of the main board body can be 2-5 times the width of the convex edge. The larger the proportion of the main board body, the higher the strength of the fixed material sheet.

[0013] In the above-mentioned fixed material sheet, the bottom of the main body and the bottom of the convex edge are both flat and flush with each other.

[0014] The bottom is a flat convex edge, which can press the pocket fabric more tightly against the platform. The bottom is a flat main board body, which is better positioned during installation and more stable after installation.

[0015] In the above-mentioned fixed material sheet, the main board body is square, the convex edge extends along the length direction of the main board body, and the convex edge extends from one end of the main board body to the other end.

[0016] The main board body is generally square in shape (not excluding the possibility of grooves at the edges of the main board body), and the convex edge is arranged in the length direction of the main board body. The convex edge of this structure is longer. After installation, the contact area between the convex edge and the pocket fabric is larger, and the convex edge can better press the material.

[0017] In the above-mentioned fixed material sheet, the main board body and the flange are an integrated structure.

[0018] The main board body and the convex edge are an integrally formed structure, and the fixed material piece of this structure is easy to process, has higher strength, and is better able to prevent deformation.

[0019] The utility model also provides a material pressing device, which comprises any one of the above-mentioned fixed material sheets.

[0020] Compared with the prior art, the advantages of the utility model are as follows:

[0021] 1. The overall strength of this set sheet is greater and it is not easy to deform. No additional gasket is needed when pressing the material. The convex edge of the set sheet can directly press the pocket fabric onto the platform. The pocket fabric is directly attached to the platform, which can prevent the skipped stitch phenomenon and make the sewing seams more beautiful.

[0022] 2. The main body of the fixed material sheet accounts for more than half of the area of ​​the entire fixed material sheet, and the thicker part accounts for more than half, so the strength of the fixed material sheet is greater. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The main board body 2 is generally square in shape (it is not excluded that a groove is provided at the edge of the main board body 2), and the convex edge 3 is arranged in the length direction of the main board body 2. The convex edge 3 of this structure is longer. After installation, the contact surface between the convex edge 3 and the pocket fabric is larger, and the convex edge 3 can better press the material.

[0038] As an embodiment, the main board body 2 and the flange 3 are an integrated structure. The main board body 2 and the flange 3 are an integrated structure, and the fixed sheet 1 of this structure is easy to process, has higher strength, and better prevents deformation.
