Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fabric processing, in particular to a special-shaped presser foot of edge skiving machine and edge skiving machine. BACKGROUND

[0002] In the production of luggage products, the edges of materials such as leather or EVA fabric usually need to be skived. This is to avoid the edges of the two layers of fabric protruding when they are sewn together, so as to ensure that the fabric is relatively flat. At present, edge skiving machines are generally used to process fabric, such as the leather edge skiving machine disclosed in Chinese patent CN 218521277 U.

[0003] However, some fabrics need to be treated by turning the edges inward and then sewing them. In this case, the fabric needs to be skived first using an edge skiving machine, and then manually folded and sent to a sewing machine for edge sewing. Manual folding is inefficient and has poor accuracy, so there is an urgent need for improvement. SUMMARY

[0004] The utility model aims to provide a special-shaped presser foot of edge skiving machine and edge skiving machine, which has the advantages of improving production efficiency and facilitating edge folding.

[0005] To achieve the above-mentioned purpose, the solution of the utility model is as follows:

[0006] A special-shaped presser foot of edge skiving machine includes a presser foot body, one side of the presser foot body is a connecting part, the connecting part has a connecting shaft hole for connecting and fixing with the edge skiving machine, and the other side of the presser foot body is a pressing part for pressing the fabric. The outer end bottom of the pressing part away from the connecting part is provided with a protruding rib protruding from the bottom of the pressing part.

[0007] Further, the protruding rib is arc-shaped.

[0008] Further, the presser foot body is shaped, the connecting part is a cylinder, and the pressing part is a rectangular body extending horizontally from one side of the cylindrical connecting part.

[0009] Further, the bottom of the pressing part protrudes a pressing protrusion, the pressing protrusion has a pressing inclined surface, the pressing inclined surface extends obliquely from the top of the front side of the pressing protrusion to the bottom of the rear side, and an acute angle is formed between the pressing inclined surface and the rear side of the pressing protrusion. The protruding rib protrudes from the pressing inclined surface, and the bottom of the protruding rib is a protruding rib sharp corner corresponding to the acute angle.

[0010] Further, the protruding rib is formed by welding a rib on the surface of the pressing part.

[0011] The embodiment also provides an edge skiving machine comprising the special-shaped presser foot.

[0012] With the above technical solution, the irregularly shaped presser foot can be fixedly installed in the edge trimming machine, providing a clamping function when trimming fabrics such as EVA. Simultaneously, the raised rib can be used to create indentations while trimming, thus forming the trimming and indentation together. This allows the fabric to be quickly and accurately folded along the indentation, saving significant time compared to manual, laborious folding, while ensuring precise and neat folds. By making simple improvements to existing equipment, production efficiency can be greatly improved. Attached Figure Description

[0018] Labeling explanation: Presser foot body 1, connecting part 11, connecting shaft hole 111, pressing part 12, pressing protrusion 121, pressing bevel 1211, rear side 1212, rib 13, rib tip 131, fabric 2, indentation 21. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] like Figures 1 to 4 As shown, an irregularly shaped presser foot for a beveling machine in this embodiment includes a presser foot body 1. One side of the presser foot body 1 is a connecting part 11, which has a connecting shaft hole 111 for connecting and fixing to a beveling machine (not shown). The other side of the presser foot body 1 is a pressing part 12 for pressing the fabric. The bottom of the outer end of the pressing part 12 away from the connecting part 11 is provided with a protruding rib 13 protruding from the bottom of the pressing part 12.

[0021] Therefore, the special-shaped presser foot can be fixedly installed in the trimming machine, and can provide a pressing function when the EVA fabric is trimmed by the trimming machine, and can also realize synchronous manufacturing of the indentation by the protruding rib 13 at the same time. Specifically, referring to Figure 5 When trimming, the protruding rib 13 can cooperate with the conveying wheel (not shown in the figure) of the trimming machine, and press an indentation 21 at a predetermined position inside the edge of the fabric 2, so that the trimming and the indentation are formed together, so that the fabric can be quickly and accurately folded along the indentation 21. By fully utilizing the existing equipment for simple improvement, the production efficiency can be greatly improved.

[0022] In this embodiment, the protruding rib 13 can be arc-shaped, and the height of the protrusion can be adjusted as needed, thereby controlling the depth of the indentation to facilitate the folding operation.

[0023] Specifically, the presser foot body 1 is special-shaped, the connecting part 11 is a cylindrical body, and the pressing part 12 is a rectangular body extending horizontally from one side of the cylindrical connecting part 11.

[0024] The bottom of the pressing part 12 can protrude a pressing protrusion 121 to adapt to the shape of the cutter of the corresponding trimming machine. The pressing protrusion 121 has a pressing inclined surface 1211, which extends obliquely from the top of the front side of the pressing protrusion 121 to the bottom of the rear side, so as to facilitate guiding the fabric. An acute angle is formed between the pressing inclined surface 1211 and the rear side 1212 of the pressing protrusion 121. The protruding rib 13 protrudes from the pressing inclined surface 1211, and the bottom of the protruding rib 13 is a protruding rib sharp corner 131 corresponding to the acute angle. The protruding rib sharp corner 131 can ensure the depth and effect of the indentation.

[0025] In this embodiment, the protruding rib 13 can be formed by welding a rib on the surface of the pressing part 12, so as to facilitate the modification of the existing product.

[0026] The embodiment also provides a trimming machine comprising the special-shaped presser foot, which can be used for fabric trimming and indentation pressing of the fabric, and has rich functions.
