Description

Technical Field

[0001] The utility model relates to the technical field of button sewing machines, and particularly relates to a feeding device of a button sewing machine. Background Art

[0002] A button sewing machine is a dedicated automatic sewing machine type that completes the sewing of regularly shaped buttons and operations with "sewing and dripping" sewing processes, such as sewing trademarks, labels, caps, etc. The most commonly used is the sewing of disc-shaped two-hole or four-hole (also known as flat buttons) buttons. By replacing various special button sewing machine accessories, a button sewing machine can sew various types of buttons such as shank buttons, metal buttons, mother-and-son buttons, wrapped-foot buttons, and windbreaker buttons.

[0003] When the existing button sewing machine is in use, it usually requires workers to manually assist in pulling the fabric to move. Manual operation may cause the movement trajectory of the fabric to be easily deviated, thus affecting the button sewing position. With a large amount of fabric, the working intensity is relatively high. Therefore, a feeding device for a button sewing machine is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a feeding device for a button sewing machine, which has the effects of keeping the traction direction unchanged, avoiding deviation during fabric feeding, and reducing the working intensity.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A feeding device for a button sewing machine includes a button sewing machine body. A button sewing groove is opened at the bottom of the inner wall of the button sewing machine body. A feeding groove is opened at the bottom of the inner wall of the button sewing machine body. A first conveying roller is arranged on the inner wall of the feeding groove. A support plate is fixedly connected to the inner wall of the button sewing machine body. A cylinder is fixedly connected to the top of the support plate. The output end of the cylinder is fixedly connected to a first telescopic rod. The bottom of the first telescopic rod is fixedly connected to an adapter frame. A second conveying roller is arranged at one end of the adapter frame. A discharge rack is fixedly connected to one end of the button sewing machine body. A conveyor belt is drivingly connected to the inner wall of the discharge rack.

[0006] By adopting the above technical solutions, when in use, the fabric is placed on the top of the first conveying roller. The first conveying rollers are distributed on both sides of the button sewing groove. During button sewing, the first conveying rollers do not convey. The cylinder is started, and the first telescopic rod drives the adapter frame to descend, so that the second conveying roller descends. The second conveying roller presses the top of the fabric to fix the fabric, making the button sewing more stable. After button sewing, the second conveying roller is lifted by an appropriate distance. In cooperation with the first conveying roller, the fabric is conveyed from the gap between the first conveying roller and the second conveying roller, facilitating the feeding of the fabric. The button-sewn fabric falls on the conveyor belt and is continuously conveyed, increasing the traction force on the fabric, keeping the traction direction unchanged, avoiding deviation during fabric feeding, and reducing the working intensity.

[0007] A further setting of the present utility model is that one end of the discharge rack is provided with a connecting seat, and a bolt is threadedly connected inside the connecting seat.

[0008] By adopting the above technical solution, the connecting seats are corresponding to both sides of the discharge rack and are fixed by bolts.

[0009] A further setting of the present utility model is that threaded holes are formed on the outer surface of the discharge rack, and the bolts extend into the threaded holes.

[0011] A further setting of the present utility model is that a second cylinder is fixedly connected to the top of the connecting seat, and a second telescopic rod is fixedly connected to the output end of the second cylinder.

[0012] By adopting the above technical solution, when in use, the second cylinder can be started, and the second cylinder drives the second telescopic rod to expand and contract.

[0013] A further setting of the present utility model is that an adjusting plate is fixedly connected to the top of the second telescopic rod, and a rotating frame is fixedly connected to one end of the adjusting plate.

[0014] By adopting the above technical solution, the adjusting plate moves up and down, thereby adjusting the height of the rotating frame.

[0015] A further setting of the present utility model is that a pressure roller is rotatably connected to the inner wall of the rotating frame, and the number of the threaded holes is three groups.

[0016] By adopting the above technical solution, the pressure roller guides the cloth after button nailing, and the discharging is stable.

[0017] A further setting of the present utility model is that an anti-static layer is fixedly connected to the outer surface of the second conveying roller, and anti-slip strips are fixedly connected to the outer surface of the anti-static layer.

[0018] By adopting the above technical solution, the anti-static layer avoids generating static electricity by rubbing with the cloth, and the anti-slip strips increase the resistance and facilitate the movement of the cloth.

[0019] A further setting of the present utility model is that a workbench is fixedly connected to the bottom of the button nailing machine body, and mounting bolts are threadedly connected inside the workbench.
