[0056] An embodiment of the present application further provides a sewing device, which includes a sewing machine table (not shown in the drawings), a sewing machine head (not shown in the drawings), and the above-mentioned replaceable cam sewing pressure plate device 1.

[0057] Among them, the sewing machine head and the replaceable cam sewing pressure plate device 1 are both installed on the sewing machine table. The sewing pressure plate 70 of the replaceable cam sewing pressure plate device 1 is located under the sewing needle of the sewing machine head, and the sewing needle can sew through the sewing channel 71 of the sewing pressure plate 70 of the replaceable cam sewing pressure plate device 1.

[0058] The sewing equipment provided in the present application can be used for sewing irregular pieces to be processed, for example, it can be used for sewing pieces to be processed that require arc-shaped stitches.

[0060] In some embodiments, the material receiving mechanism includes a material receiving arm, a material receiving moving component, and a material receiving box. The material receiving moving component drives the material receiving arm to collect the sewn pieces into the material receiving box.

[0061] It is understandable that in the present application, manual collection can also be used to collect the cut pieces after sewing. Without violating the inventive concept of the present application, no special limitation is made on the material collection method.

[0062] In some embodiments, the sewing device further includes a control mechanism (not shown in the figure), and the control mechanism is electrically connected to the moving mechanism 60, the rotating mechanism 80, the sewing machine head and the material receiving mechanism.

[0065] When the replaceable cam sewing press plate device 1 provided in the present application is actually used, the specific process is as follows:

[0066] When the sewing pressing plate 70 presses the piece to be processed into the designated position, the cam concave plate 40 is installed on the base 10, and the cam concave plate 40 and the cam rotor 30 provided on the cam substrate 20 are located in the same horizontal plane and keep the position fixed. The moving mechanism 60 first drives the cam rotor 30 to move along the X-axis direction, so that the cam rotor 30 abuts against the first side 41 on the cam concave plate 40, and then drives the cam rotor 30 to move along the X-axis and Y-axis directions at the same time. Due to the limiting effect of the first side 41, the sewing pressing plate 70 with the same shape of the sewing channel 71 moves along the X-axis and Y-axis directions at the same time, and then cooperates with the reciprocating movement of the sewing needle in the Z-axis direction, so that the linear or non-linear sewing stitches of the piece to be processed can be sewn.

[0067] It should be noted that the sewing channel 71 can be a linear channel. When the first side 41 and the sewing channel 71 are both linear, the moving mechanism 60 first drives the cam rotor 30 to move along the X-axis direction, so that the cam rotor 30 abuts against the first side 41 on the cam concave plate 40; then drives the cam rotor 30 to move along the Y-axis direction. The sewing channel 71 can be non-linear, such as an arc shape. When the first side 41 and the sewing channel 71 are both arc-shaped, the moving mechanism 60 first drives the cam rotor 30 to move along the X-axis direction, so that the cam rotor 30 abuts against the first side 41 on the cam concave plate 40; then drives the cam rotor 30 to move along the X-axis and Y-axis directions at the same time.

[0068] The replaceable cam sewing press plate device 1 provided in the present application has the following beneficial effects:

[0069] The replaceable cam sewing pressure plate device 1 provided in the present application can use a flat sewing machine to sew arc-shaped stitches. When arc-shaped stitches of different shapes need to be sewn, only the cam concave plate 40 and the sewing pressure plate 70 of different shapes need to be replaced. There is no need to replace the sewing pattern head, which saves the cost of using the pattern head and reduces the production cost. The sewn product quality consistency is high, the processing efficiency is high, the operation is simple, and the manual participation is greatly reduced, saving time and effort.

[0070] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0071] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
