[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] Example 1: Figure 1-7As shown, an automatic feeding sewing machine includes a computer sewing machine 1, which adopts a two-synchronous four-automatic computer sewing machine or a three-synchronous four-automatic computer sewing machine on the market; it also includes a feeding device 2 arranged on one side of the computer sewing machine 1; the computer sewing machine 1 is provided with a thread breakage detector (not shown); the feeding device 2 includes a bottom plate 21 and a material rack 22 and a pushing device 23 mounted on the bottom plate 21; the material rack 22 includes a base frame 221, a plurality of limiting members 222 and an adjusting member 223; the limiting member 222 is used to limit the position of the placed product, and is designed according to the shape of the product, and can be made of iron wire winding or plate-shaped material. This design provides a structure for sewing hexagonal products. Therefore, in this embodiment, the limiting member 222 adopts a limiting plate and is provided with six pieces. The six limiting members 222 are designed to be distributed around and can be installed on the base frame 221 by adjusting the position at least up and down through the adjusting member 223 to adjust the height to adapt to products of different thicknesses. In addition, this design also provides a method for adjusting the internal and external positions to adapt to products of different sizes; the bottom of the limiting member 222 is reserved with a feed port 201; the pushing device 23 includes a pushing drive device 231 and a pushing block 232. The pushing drive device 231 can be driven by a cylinder, a motor, a hydraulic cylinder, etc. In this design, a cylinder drive is adopted, and the pushing surface of the pushing block 232 cooperates with the product to form a V-shaped structure; the pushing block 2 32 is arranged on one side of the feeding port 201; the pushing drive device 231 is fixed on the bottom plate 21 and the power output end is connected to the pushing block 232 to drive the pushing block 232 to move toward the side of the workbench of the computer sewing machine 1. This design is used to sew one end surface of the ball product material. The six limiting members 222 form a feeding trough, and the lower end of the feeding trough has a feeding port 201. Before use, the position of the limiting member 222 is manually adjusted according to the thickness, width and length of the product. The feeding port 201 reserves a height of the thickness of two pieces of product. The six limiting members 222 just form a space for the product to be placed in, and the product is limited. After the adjustment is completed, the product is placed on the feeding trough from the top of the feeding trough manually. The computer sewing machine 1 is provided with a thread break detector which can automatically detect whether the thread is broken or in a straightened state. When there is no bottom thread, no upper thread or the upper thread is broken in the middle of sewing, the machine will automatically stop working to prevent the machine from continuing to work without thread and damaging the material, thereby ensuring the normal use of the machine. The automatic loading structural design allows one staff member to manage multiple sewing machines at the same time, saving a lot of labor, improving work efficiency and having high safety performance.

[0026] The feeding device 2 is located on the right side of the computer sewing machine 1; the base frame 221 includes two vertical plates 2211 and several hexagonal ring frames 2212. In this design, two hexagonal ring frames 2212 are designed; the vertical plates 2211 are symmetrically distributed and installed on the bottom plate 21 in the front and back; the two hexagonal ring frames 2212 are designed to be distributed up and down and fixed between the two vertical plates 2211; each of the limit members 222 is connected to a side surface of the inner side of the hexagonal ring frame 2212 through an adjusting member 223, and the upper end of each side surface of the hexagonal ring frame 2212 is provided with two "U"-shaped openings 2212-1; the vertical plate 2211 is provided with a strip hole 2211-1 corresponding to the "U"-shaped openings 2212-1 on the front and back sides; the adjusting member 223 includes an adjusting rod 2231 and two adjusting nuts 2 232; one end of the adjusting rod 2231 is fixedly connected to the limit member 222, and the adjusting rod 2231 can be fixed to the limit member 222 by welding or threaded connection, and the other end passes through the "U"-shaped opening 2212-1, and the adjusting rods 2231 on the front and rear sides are also passed through the bar hole 2211-1; the adjusting nut 2232 is threadedly connected to the adjusting rod 2231; the two adjusting nuts 2232 on the adjusting members 223 on the front and rear sides respectively touch the outer side of the vertical plate 2211 and the inner side of the hexagonal ring frame 2212, and the two adjusting nuts 2232 on the adjusting members 223 at other positions respectively touch the inner and outer sides of the "U"-shaped opening 2212-1. When the position of the limit member 222 needs to be adjusted, loosen the corresponding nut, move the limit member 222 to the specified position, and then lock it.

[0027] The loading device 2 also includes a guide plate 24; the guide plate 24 is installed on the base plate 21; a guide groove is provided in the guide plate 24; the right end of the guide groove is connected to the feed port 201, and the left end is close to the processing part of the workbench of the computer sewing machine 1; the material rack 22 is arranged vertically; when the material driving device pushes the pushing block 232 to move to the right, the product escapes from the bottom of the material rack 22 and enters the guide groove of the guide plate 24, moves along the guide groove and is sent out from the left end of the guide groove to the processing part of the computer sewing machine 1.

[0028] The right end of the guide plate 24 is V-shaped to match the shape of the product and improve the stability of the docking.

[0029] The working principle of this embodiment is as follows:

[0030] The six limiting members 222 form a discharge trough, and the lower end of the discharge trough has a feeding port 201. Before use, the position of the limiting member 222 is manually adjusted according to the thickness, width and length of the product. The feeding port 201 reserves a height of the thickness of two products. The six limiting members 222 just form a space for the product to be placed in, and the product is limited. After the adjustment is completed, the product is manually placed in the discharge trough from the top of the discharge trough, and then a counterweight block is placed above the product. During use, the pushing device 23 pushes the two products at the bottom of the discharge trough out and pushes them to the processing position of the workbench of the computer sewing machine 1, and then the computer sewing machine 1 automatically performs sewing processing. The computer sewing machine 1 is provided with a thread break detector that can automatically detect whether the thread is broken or whether it is in a straightened state to ensure the normal use of the machine.

[0031] Embodiment 2: The material rack 22 is designed to be inclined; the upper end of the material rack 22 is located at the upper right side of the computer sewing machine 1, and the lower end is close to the processing part of the workbench of the computer sewing machine 1. This design does not require the use of a guide plate 24, and the material outlet 201 of the material rack 22 is designed to be close to the processing part, so that the product only needs to be pushed out of the material rack 22 to reach the processing area, and the sewing machine can sew the product.

[0032] The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
