[0002] On sewing production lines in industries such as apparel and home textiles, after the fabric is sewn by the sewing machine, it needs to be removed from the sewing station and moved away in a timely and efficient manner (i.e., unloading) to allow for subsequent processes or to make room for the next piece of fabric. Traditional manual unloading methods are inefficient, labor-intensive, and difficult to match the pace of automated production lines. Utility Model Content

[0014] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 and Figure 2As shown, a fabric feeding device 100 is mounted on a base 11 and is used to remove and feed the fabric from the sewing station after the sewing machine 12 has sewn the fabric. The fabric feeding device 100 includes a support part 2, a feeding execution part 3, and a swing execution part 4.

[0015] One end of the support part 2 is fixed to the base 11, and the unloading execution part 3 and the swing execution part 4 are disposed at the other end of the support part 2. At least a portion of the unloading execution part 3 is rotatable about an axis parallel to the plane of the base 11, and the tangential direction of the rotating portion of the unloading execution part 3 near the upper surface of the base 11 is set as the unloading direction. The swing execution part 4 connects the support part 2 and the unloading execution part 3. The movement of the swing execution part 4 causes the unloading execution part 3 to have an unloading station that is in contact with the fabric on the base 11 and a standby station that is suspended above the base 11. When the unloading execution part 3 is in the unloading station, its unloading end will be in contact with the base 11, thereby pulling the fabric on the base 11 toward the unloading direction. When the unloading execution part 3 is in the standby station, its unloading end will be lifted.

[0016] Specifically, in combination Figure 3 and Figure 4 As shown, one end of the unloading execution unit 3 is rotatably connected to the support unit 2. The unloading execution unit 3 includes at least two drive wheels 31 and a drive belt 32 sleeved on the drive wheels 31. Multiple drive wheels 31 are connected by a connecting plate 34 to make them have a constant spacing. At least one drive wheel 31 is connected to a driver 33. The driver 33 drives the drive wheel 31 to rotate and the rotation is transmitted to another drive wheel 31 through the drive belt 32.

[0017] In some embodiments of this application, the transmission belt 32 near the outer wall of the base 11 is configured as a feeding end for contacting the fabric on the base 11. That is, by the transmission belt 32 contacting the fabric, the fabric is slid along the feeding direction to achieve the feeding of the fabric.

[0018] In a preferred embodiment of this application, a feed wheel is coaxially fixed to the side of the transmission wheel 31 away from the support portion 2. The feed wheel has a diameter larger than the outer wall of the transmission wheel 31 connected to it and the cooperating transmission belt 32. The end of the feed wheel near the base 11 is configured as a feed end for contacting the fabric on the base 11. Furthermore, the outer edge of the feed wheel is made of rubber material to obtain greater friction with the fabric, facilitating the feeding of the fabric.

[0019] In some embodiments of this application, the oscillating actuator 4 is a motor and is disposed at the rotatable connection between the unloading actuator 3 and the support 2. It includes a first part and a second part capable of relative rotation, the first part and the second part being respectively constructed as the output shaft and body of the motor. The first part and the second part are fixed to the unloading actuator 3 and the support 2, respectively.

[0020] In a preferred embodiment of this application, the swing actuator 4 is a cylinder, including a first part and a second part capable of telescopic movement. The first part and the second part are respectively configured as the drive end and the body of the cylinder. The first part is hinged to the support part 2, and the second part is hinged to the middle of the unloading actuator 3 or the end of the unloading actuator 3 away from the support part 2.

[0021] In addition, the support part 2 includes a bracket 21 fixed to the base 11. The bracket 21 is configured as an L-shaped structure, with one end fixed to the base 11 and a mounting plate 22 arranged vertically at the end away from the base 11. The feeding execution part 3, the swing execution part 4, and the driver 33 are all connected to the mounting plate 22.

[0022] The feeding execution unit 3 also includes a tensioning wheel 35, the rim of which abuts against the outer wall of the transmission belt 32. A slotted hole 36 is provided on the connecting plate 34, and the tensioning wheel 35 is disposed in the slotted hole 36, allowing it to slide along the length of the slotted hole 36 to adjust the tension on the transmission belt 32. A locking structure, such as a nut, is also provided, allowing the tensioning wheel 35 to be locked in a specific position within the slotted hole 36.
