Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] A curtain edge-sealing sewing machine includes a front frame 1, a conveyor plate 2 connected to the rear of the front frame 1, and a rear frame 3 located behind the conveyor plate 2. The front frame 1 has a first sewing section and a second sewing section, the conveyor plate 2 has a turning and ironing section, and the rear frame 3 has a finishing sewing section.

[0026] The front frame 1 includes two interconnected support frames 500. A crossbar is located at the frontmost end of the front support frame 500, and a selvage fabric conveying wheel 102 is rotatably mounted on the crossbar. A guide mechanism 600 is provided on this support frame 500. The guide mechanism 600 includes two parallel guide rods 601, each with two sliding rings 602. A fixing screw 604 is mounted on each sliding ring 602, and the fixing screw 604 is screwed inwards to abut against the guide rod 601, thereby fixing the sliding ring 602. A connecting rod 603 is fixedly mounted between the sliding rings 602, and two sliding rings 602 are also slidably mounted on the connecting rod 603. The fixing screw 604 is used to keep the sliding rings 602 fixed. The selvage fabric is pulled out by the selvage fabric conveying wheel 102 and passes through the guide mechanism 600.

[0027] The support frame 500 is provided with a first mold 101 located behind the guide mechanism 600. A decorative bud thread conveying wheel 103 is provided on the side of the support frame 500. A limiting plate 900 is provided between the decorative bud thread conveying wheel 103 and the first mold 101. The limiting plate 900 is provided with several vertical grooves 901. After the decorative bud thread is pulled out from the decorative bud thread conveying wheel 103, it passes through the vertical grooves 901 of the limiting plate 900 and enters the first mold 101.

[0028] The first mold 101 includes a base plate 1011 bolted to a support frame 500 located at the front. A limiting plate 1012 is bolted to one side of the base plate 1011. The outer fabric with the fixed edge travels rearward between the base plate 1011 and the limiting plate 1012 after passing through a guide mechanism 600. A lifting plate 1013 is provided on the other side of the base plate 1011 to raise the height. An extension plate 1014 is provided on the lifting plate 1013. A folding mold 1015 is provided at the free end of the extension plate 1014 facing the limiting plate 1012. The decorative bud line is folded after passing through the folding mold 1015. A serpentine hanger 1016 is provided at the front end and back of the folding mold 1015.

The serpentine hanger 1016 can increase the stability of the decorative bud line during its movement. The decorative bud thread, after being folded and sewn, has a 3mm misalignment with the outer edge of the bottom. This 3mm misalignment technique allows sufficient space for subsequent turning and sewing, thereby increasing the aesthetic appeal.

[0029] A first sewing machine 100 is mounted on the support frame 500 behind the first mold 101. The first sewing machine 100 sews the edge-fixed outer fabric and the folded decorative gusset. A guide roller 700 is located at the rear end of the first sewing machine 100. This guide roller 700 is driven by a motor and has an annular groove of a certain width. The depth of the annular groove is equal to the thickness of the sewn fabric strip, which serves to convey, guide, and position the fabric strip, preventing it from deviating from its intended path.

[0030] A roll box is located at the rear of the mop roller 700. The cloth strip enters the roll box from the front, curls inward, and is then sent out from the rear. This can further maintain the stability of the cloth strip in its direction of travel and avoid problems such as deviation.

[0031] A horizontal bar is installed above or below the front side of a support frame 500 located at the rear. A sewing machine with a fixed edge backing fabric is mounted on this horizontal bar. A guide mechanism 600 is also installed on this horizontal bar. Behind the guide mechanism 600 is a second mold 201, behind which is a second sewing machine 200, and behind the second sewing machine 200 is a dragging roller 700. The fixed edge backing fabric is pulled out from the sewing machine with the fixed edge backing fabric and enters the second mold 201 through the guide mechanism 600. After passing through the second mold 201, it continues to move backward via the second sewing machine 200 and the dragging roller 700.

[0032] The second mold 201 includes a base plate 2011, on which a bottom layer partition plate 2012 and a top layer partition plate 2013 are disposed. The fabric with the bottom and decorative gusset sewn together enters the second sewing machine 200 through the space between the bottom layer and the base plate 2011, while the sewn-up backing fabric enters the second sewing machine 200 through the space between the top layer partition plate 2013 and the bottom layer partition plate 2012. After the second sewing machine 200 sews the two together, the fabric continues to be transported to the position of the conveyor plate 2 via the drag roller 700.

[0033] The conveyor plate 2 is equipped with a flipping group 304, which includes a clamping frame 3041. The clamping frame 3041 is equipped with two clamping wheels, one above the other. A vertical frame 3042 is provided behind the clamping frame 3041, and a horizontal frame 3043 is provided behind the vertical frame 3042. The fabric strip is flipped for the first time after passing through the clamping frame 3041, the vertical frame 3042 and the horizontal frame 3043.

[0034] A third mold 302 is located on the conveyor plate 2 behind the tilting frame. Behind the third mold 302 is an iron 300, and behind the iron 300 are a mopping roller 700 and a drive winding roller 303. The mopping roller 700 is equipped with an adjustment panel 701, which connects to all the mopping rollers 700 and is used to adjust their rotation speed. A mounting frame 800 is provided on the conveyor plate 2, and a cylinder 801 is mounted on the mounting frame 800. The iron 300 is located at the lower end of the telescopic rod of the cylinder 801.

The flattening section 3021 includes a support 30211, on which a shuttle-shaped ring 30212 is provided. One side of the shuttle-shaped ring 30212 is provided with an outwardly protruding folded edge 30213. When the fabric strip passes through, the overlapping part due to sewing passes through the folded edge 30213, stretching and expanding the fabric strip as a whole, so that it unfolds to a certain extent. The flipping section 3022 includes an outer open inner shrinking tube 30221. The inner shrinking tube 30221 is a two-layer structure. One side of the inner shrinking tube 30221 is provided with an inwardly protruding inner strip 30222. The tail of the inner shrinking tube 30221 is provided with a strip-shaped outlet 30223. When the fabric strip passes through, the overlapping part due to sewing passes through the inner strip 30222. The two sides of the fabric strip are flipped a second time along the two layers of the inner shrinking tube 30221, and finally enter the iron 300 from the strip-shaped outlet 30223 for ironing.

[0036] The strips of cloth that have passed through the iron 300 and mop roller 700 are wound up by the active winding roller 303.

[0037] The rear frame 3 includes a support frame 500. A fourth mold 401 is located at the front end of the support frame 500, and a fabric strip conveyor wheel 402 is located on the side. A third sewing machine 400 is located behind the fourth mold 401, and a fabric dragging wheel 700 is located behind the third sewing machine 400. After the fabric strip is pulled out from the fabric strip conveyor wheel 402, it passes through the fourth mold 401 and enters the third sewing machine 400, where it is sewn to form the finished product.

[0038] An L-shaped fixing frame 403 is provided between the fabric conveying wheel 402 and the fourth mold 401. The fixing frame is provided with several positioning rods 404. Preferably, there are two positioning rods 404. Two sets of upper and lower screws are horizontally inserted between the positioning rods 404. Positioning is achieved by clamping the screws and the two positioning rods 404.

[0039] The fourth mold 401 includes a double-layered folding tube 4011 with a U-shaped expanding cross-section, mounted on the rear frame 3. The inner front end of the double-layered folding tube 4011 has an outwardly protruding arc-shaped portion 4012. A lateral extension tube 4013 with an expanding structure is located on the back of the arc-shaped portion 4012. A shaping tube 4014 is fixedly mounted on one side of the lateral extension tube 4013. A strip-shaped outlet 4015 is located at the rear end of the double-layered folding tube 4011. A strip of fabric enters the double-layered folding tube 4011 between the lateral extension tube 4013 and the shaping tube, and then enters the third sewing machine 400 through the strip-shaped outlet 4015. The curtain body enters the third sewing machine 400 between the inner layers of the double-layered folding tube 4011. Upon entering the third sewing machine 400, the fabric strip covers the curtain body, and the third sewing machine 400 sews the fabric strip and the curtain body together.
