[0030] Embodiment 1

[0031] A hemming machine for making fans, such as Figure 1 As shown, the fan 40 includes a fan frame 41 and a fan surface 42, and the fan surface 42 is pre-fixed on the fan frame 41 by means of glue bonding or the like; the fan frame 41 can be but not limited to a metal fan frame 41, a wooden fan frame 41, a bamboo fan frame 41 or a plastic fan frame 41, and the fan surface 42 can be but not limited to a cloth fan surface 42, a paper fan surface 42 or a plastic fan surface 42, and the like; the fan frame 41 is roughly annular in shape, and a connection portion 43 is provided at its annular interface for subsequent fixed connection with a fan handle; the edge of the fan surface 42 is pre-fixed on the fan frame 41 by means of glue bonding or the like, and the needle thread for hemming the fan frame 41 is also sewn on the edge of the fan surface 42 at the same time, so as to further fix the fan surface 42 on the fan frame 41.

[0032] like Figure 2 As shown, the hemming machine includes a rotating device 10, a pressing wheel device 20 and an hemming sewing device 30, wherein the pressing wheel device 20 and the hemming sewing device 30 are arranged on one side of the rotating device 10, wherein

[0033] The rotating device 10 is used to drive the fan 40 to rotate around the axial direction, so as to sequentially send the fan frame 41 of the fan 40 to the hemming sewing device 30;

[0034] The pressing wheel device 20 is used to press the fan frame 41 of the fan 40 onto the hemming sewing device 30;

[0035] The hemming sewing device 30 is used to perform hemming sewing on the fan frame 41 of the fan 40 using needle and thread.

[0036] When the hemming machine of the utility model is working, the rotating device 10 is first used to drive the fan 40 to rotate. When the fan 40 rotates, the fan frame 41 on the edge of the fan 40 will arrive at the hemming sewing device 30 in sequence, and then the pressing wheel device 20 is used to press the fan frame 41 of the fan 40 onto the hemming sewing device 30 to prevent the fan frame 41 from positional displacement. Then, the hemming sewing device 30 is used to hem and sew the fan frame 41 of the fan 40 to automatically complete the hemming process of the fan 40, thereby improving the hemming efficiency of the fan 40.

[0037] like Figure 3 As shown, the rotating device 10 includes a rotating tray 11, a rotating pressure plate 12 and a rotating drive mechanism. The rotating pressure plate 12 is axially detachably arranged on the rotating tray 11. When the rotating pressure plate 12 is arranged on the rotating tray 11, the fan surface 42 of the fan 40 is pressed against the rotating tray 11. When the rotating pressure plate 12 is separated from the rotating tray 11, the fan surface 42 of the fan 40 is released from the rotating tray 11. The rotating drive mechanism is connected to drive the rotating tray 11 to rotate axially, thereby driving the fan 40 to rotate axially.

[0038] The diameters of the rotating tray 11 and the rotating pressure plate 12 are both smaller than the inner diameter of the fan frame 41, so that the fan frame 41 and the edge of the fan surface 42 pre-fixed outside the fan frame 41 are exposed outside the rotating tray 11 and the rotating pressure plate 12 for the hemming sewing device 30 to perform hemming sewing.

[0039] Preferably, the diameter of the rotating tray 11 is larger than the diameter of the rotating pressure plate 12 so as to increase the supporting area for the fan 40 .

[0040] A handle 13 is provided on the side of the rotating pressure plate 12 facing away from the rotating tray 11 , so that the fan maker can easily lift the rotating pressure plate 12 from the rotating tray 11 through the handle 13 .

[0041] The rotary drive mechanism includes a rotary motor 14, a driving wheel 15, a driven wheel 16, a transmission belt 17 and a rotary shaft 18. The driving wheel 15 is coaxially arranged on the output shaft of the rotary motor 14, the driven wheel 16 is coaxially arranged on the rotary shaft 18, and the transmission belt 17 is transmission-connected between the driving wheel 15 and the driven wheel 16; the rotary tray 11 is vertically arranged on the rotary shaft 18.

[0042] The driving force of the rotating motor 14 is transmitted to the rotating shaft 18 through the driving wheel 15, the transmission belt 17 and the driven wheel 16 in sequence, and drives the rotating tray 11 to rotate axially through the rotating shaft 18. The fan 40 rotates together with the rotating tray 11 due to the friction between the fan surface 42 and the rotating tray 11, and the rotating pressure plate 12 also rotates together with the fan 40 due to the friction between the fan surface 42 of the fan 40.

[0043] The rotating device 10 also includes a chassis 19 and a base plate 110. The rotating tray 11 and the rotating pressure plate 12 are arranged above the chassis 19, and the rotating drive mechanism and the base plate 110 are arranged inside the chassis 19; the rotating shaft 18 passes through the chassis 19 and the base plate 110, and is rotatably connected to the chassis 19 and the base plate 110 through a rotating shaft flange 111.

[0044] like Figure 4 and 5 As shown, the pressing wheel device 20 includes a pressing frame wheel 21 and a pressing wheel moving mechanism, and the pressing wheel moving mechanism is connected to drive the pressing frame wheel 21 to move relative to the fan frame 41 of the fan 40. When the pressing frame wheel 21 is close to the fan frame 41 of the fan 40, the fan frame 41 of the fan 40 is pressed against the hemming sewing device 30, and when the pressing frame wheel 21 is away from the fan frame 41 of the fan 40, the fan frame 41 of the fan 40 is released from the hemming sewing device 30.

[0045] The hemming sewing device 30 includes a sewing head 31 and a feed dog mechanism 32 which are arranged opposite to each other in an upper and lower direction. The pressing wheel device 20 is arranged next to the sewing head 31. When the pressing frame wheel 21 is close to the fan frame 41 of the fan 40, it is located above the feed dog mechanism 32 and presses the fan frame 41 of the fan 40 against the feed dog mechanism 32.

[0046] The feed dog mechanism 32 drives the fan frame 41 from one side to move to the bottom of the sewing machine head 31 for hemming sewing through reciprocating motion. The reciprocating motion direction of the feed dog mechanism 32 is tangent to the fan frame 41, and the reciprocating motion of the feed dog mechanism 32 is synchronized with the rotational motion of the rotating device 10, that is, the movement speed of the feed dog is the same as the linear speed of the fan frame 41.

[0047] The pressure wheel moving mechanism includes a pressure wheel connecting swing arm 22, an L-shaped arm 23, a horizontal rotating shaft 24, a connecting rod connecting swing arm 25 and an elastic tension spring 26. The first arm portion of the L-shaped arm 23 is rotatably connected to one end of the pressure wheel connecting swing arm 22 around the vertical axis, and the second arm portion of the L-shaped arm 23 is coaxially arranged with one end of the horizontal rotating shaft 24 along the horizontal axis; the elastic tension spring 26 is connected to the other end of the horizontal rotating shaft 24 through the connecting rod connecting swing arm 25; the pressure frame wheel 21 is rotatably arranged on the other end of the pressure wheel connecting arm.

[0048] In this embodiment, the elastic tension spring 26 is electrically driven through the connecting rod connected to the swing arm 25 to drive the horizontal rotating shaft 24 to rotate. When rotating, the horizontal rotating shaft 24 drives the L-shaped arm 23 to rotate together, thereby causing the pressure frame wheel 21 on the pressure wheel connected to the swing arm 22 to press or loosen the fan frame 41 of the fan 40; the pressure wheel connected to the swing arm 22 is manually rotated around the vertical axis relative to the L-shaped arm 23, so that the pressure frame wheel 21 moves to the top of the feed dog mechanism 32 or leaves the top of the feed dog mechanism 32.

[0049] In this embodiment, the sewing machine head 31 is a double-needle hemming machine head.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
