One side of the lifting plate 15 contacts the surface of the folding plate 21. The rotating assembly is installed between the folding plate 21 and the mounting seat 11. The rotating assembly is used to drive the folding plate 21 to rotate. When the folding plate 21 can be rotated from a vertical state to a horizontal state, the folding position of the cloth can be folded above the thin plate 16, thereby realizing automatic folding of the cloth. The conveying component includes a driving assembly and two transmission rollers 32. The two transmission rollers 32 are arranged up and down and are rotatably arranged on the top of the mounting seat 11. The driving assembly is located between the mounting seat 11 and the two transmission rollers 32. The folded fabric enters between the two transmission rollers 32, and the driving assembly can drive two more transmission rollers 32 to rotate, so that the transmission rollers 32 can drive the folded fabric to be transported, and the folded fabric is transported to the sewing area for sewing at the folded edge, without manual feeding; The pressing component includes a pressing platform 37, a transmission component, a telescopic component and two pressing plates 38. The pressing platform 37 is fixed to the top of the mounting seat 11 and close to the side of the mounting hole 52.

When the lifting plate 15 needs to be moved downward, the controller controls the electric push rod 14 to work, and the electric push rod 14 can drive the lifting plate 15 to move downward. The lifting plate 15 drives the limiting rod 13 to slide on the limiting cylinder 12 to realize the downward movement of the lifting plate 15. At the same time, when the lifting plate 15 moves, due to the setting of the limiting cylinder 12, it can limit the lifting plate 15.

[0032] like Figure 1-Figure 9 As shown, the pressing assembly includes a mounting frame 17, a screw rod 18, a rotating wheel 19 and two guide rods 20.

When the lifting plate 15 moves downward to the top of the limiting cylinder 12, the thin plate 16 moves downward with the lifting plate 15, so that the lifting plate 15 and the thin plate 16 are not in contact with the folding plate 21. At this time, under the action of the spring 31, the rack 29 can be driven to move upward. When the rack 29 moves, it drives the first gear 28 to rotate, and the first gear 28 drives the driven wheel 25 to rotate. Under the action of the transmission belt 26, when the driven wheel 25 rotates, it can drive the driving wheel 24 to rotate, so that the folding plate 21 can be rotated through the rotating rod 22, so that the folding plate 21 can be rotated from a vertical state to a horizontal state, so that the folding position of the cloth can be folded above the thin plate 16, realizing automatic folding of the cloth.

The guide is located between the L-shaped frame 39 and the two clamping plates 38. It should be noted here that a heating plate for heating is provided inside the pressing plate 38, which can heat-press the folded fabric; When one swing rod 42 swings, the rotating shaft 41 is used to make the two swing rods 42 swing, so that the two clamping plates 38 can be alternately lifted and lowered through the four first hinged rods 43. The two clamping plates 38 can be used to alternately perform hot pressing on the folded edges of the fabric, and further flatten the folded fabric, which can effectively prevent the folded edge from warping up due to the toughness of the fabric itself, and is beneficial to improving the effect of the folding sewing.

[0037] like Figure 1-Figure 9 As shown, the guide member includes two strip grooves 46 and two guide blocks 47. The two strip grooves 46 are symmetrically opened on one side of the L-shaped frame 39. Each guide block 47 is slidably arranged inside a strip groove 46. One end of each guide block 47 is connected to a clamping plate 38. By utilizing the sliding connection between the guide block 47 and the strip groove 46 , the pressing plate 38 can be guided so that the pressing plate 38 can move along the length direction of the strip groove 46 .

[0038] like Figure 1-Figure 9As shown, the transmission assembly includes a rotating disk 44, a second hinged rod 45, a first sprocket 48, a second sprocket 49 and a chain 50.

[0039] like Figure 1-Figure 9 As shown, a material guide plate 51 is provided at one end of the lifting plate 15 away from the driving roller 32. The material guide plate 51 is fixedly connected to the lifting plate 15. The material guide plate 51 is inclined. The material guide plate 51 is used to guide the cloth.

[0040] The specific working process of the present invention is as follows: First, the mounting base 11 can be fixed to one side of the sewing machine through the mounting hole 52 and the bolts matched with the mounting hole 52, so that the folded fabric can be directly put into the sewing machine for sewing; The cloth to be folded is placed above the lifting plate 15, and the position to be folded is made to fit on one side of the folding plate 21, and the rotating wheel 19 is turned. The rotating wheel 19 can drive the screw rod 18 to rotate. Due to the threaded fit between the screw rod 18 and the mounting frame 17, when the screw rod 18 rotates, it can drive the thin plate 16 to move downward. At this time, the guide rod 20 slides on the mounting frame 17 to guide the movement of the thin plate 16. The controller controls the electric push rod 14 to work, and the electric push rod 14 can drive the lifting plate 15 to move downward. The lifting plate 15 drives the limiting rod 13 to slide on the limiting cylinder 12 to realize the downward movement of the lifting plate 15. At the same time, when the lifting plate 15 moves, due to the setting of the limiting cylinder 12, the lifting plate 15 plays a role of limiting. When the lifting plate 15 moves downward to the top of the limiting cylinder 12, the thin plate 16 moves downward with the lifting plate 15, so that the lifting plate 15 and the thin plate 16 are not in contact with the folding plate 21. At this time, the rack 29 can be driven to move upward under the action of the spring 31. When the rack 29 moves, it drives the first gear 28 to rotate. The first gear 28 drives the driven wheel 25 to rotate. Under the action of the transmission belt 26, when the driven wheel 25 rotates, it can drive the driving wheel 24 to rotate, so that the folding plate 21 can be rotated through the rotating rod 22, so that the folding plate 21 can be rotated from a vertical state to a horizontal state, so that the folding position of the cloth can be folded above the thin plate 16, and the automatic folding of the cloth can be realized; Then, the folded fabric enters between the two transmission rollers 32, and the controller controls the motor 34 to work. The motor 34 can drive the transmission roller 32 connected thereto to rotate, and the second gear 35 and the third gear 36 can drive another transmission roller 32 to rotate, so that the two rotating transmission rollers 32 can realize the transmission of the fabric, without manual loading; The cloth is first conveyed to the top of the pressing table 37 through the two driving rollers 32. When the driving roller 32 rotates, it can drive the first sprocket 48 to rotate. Under the action of the chain 50, the first sprocket 48 can drive the second sprocket 49 to rotate. The second sprocket 49 drives the turntable 44 coaxially fixed thereto to rotate. Under the action of the second hinged rod 45, when the turntable 44 rotates, it can drive the swing rod 42 to swing around the axis of the rotating shaft 41. When one swing rod 42 swings, the rotating shaft 41 is used to make the two swing rods 42 swing, so that the two pressing plates 38 can be alternately lifted and lowered through the four first hinged rods 43. The two pressing plates 38 can be used to alternately perform hot pressing on the folded edges of the cloth, and further flatten the folded cloth, which can effectively prevent the folded edge from warping due to the toughness of the cloth itself, which is beneficial to improving the effect of folding sewing. With the continued conveyance of the driving roller 32, the heat-pressed fabric can be conveyed to the folded edge of the sewing area for sewing.
