DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Reference Figure 1A sinking structure for an industrial sewing machine comprises a body 1, a transmission element 2 is arranged on the body 1, the transmission element 2 comprises a feeding assembly 3, a first slide rail 4 and a first cylinder 5, the feeding assembly 3 slides left and right on the first slide rail 4 through the first cylinder 5, the feeding assembly 3 comprises a second slide rail 6, a first feeding part 7 and a second feeding part 8, a second cylinder 9 is arranged on the second slide rail 6, a tray 10 is arranged on the first feeding part 7 and the second feeding part 8, a sewing plate 11 is arranged on the upper end of the tray 10 on the first feeding part 7, a sinking part 12 is opened on the body 1, the sinking part 12 is located at the front end of the sewing plate 11, two parallel sliding grooves 14 are arranged on the body 1, and a lifting cylinder 15 is arranged on the two parallel sliding grooves 14, a connecting plate 16 is arranged in the middle of the two lifting cylinders 15 for connection, a lifting shaft 17 is arranged at the front end of the lifting cylinder 15, and a lifting hole 18 adapted to the lifting shaft 17 at the front end of the lifting cylinder 15 is arranged on the tray 10.

[0022] First, place the cloth on the tray 10 on the first feeding part 7 for sewing operation. The feeding assembly 3 realizes the feeding operation by sliding left and right on the first slide rail 4 through the first cylinder 5. When the feeding assembly 3 slides to the top of the lifting cylinder 15 on the left side of the fuselage 1, the lifting cylinder 15 pushes the lifting shaft 17 into the lifting hole 18 on the tray 10, and the second cylinder 9 pushes the second feeding part 8 forward on the second slide rail 6 to feed the tray 10 to the rear end of the sinking part 12. At this time, put the cloth Place it on the tray 10. Because the sinking part 12 is provided with a sinking plate 13, the sinking plate 13 is inclined from right to left, and a downward groove appears. Therefore, the lower end of the cloth will vertically enter the edge of the sinking part 12. The tray 10 on the first feeding part 7 is pushed backward by the second cylinder 9, and the cloth on the tray 10 on the first feeding part 7 is transferred to the tray 10 on the second feeding part 8, and is fixed by pressing with the sewing plate 11, so as to avoid wrinkles during sewing.

[0023] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.
