Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, and in particular to a device for interlocking and sewing of layered fabrics used in curtain production. Background Technology

[0002] Curtains are made of materials such as cloth, linen, and gauze, and serve to block sunlight, insulate against heat, and regulate indoor light. The edges of the curtains need to be sewn shut, and the top of the curtains needs to be perforated and threaded onto the curtain rod. Because the fabric is soft, the top of the curtain needs sufficient support to prevent it from being too soft and unable to move smoothly. This area requires reinforcement for both aesthetics and practicality. Typically, Oxford cloth is interwoven at the top of the curtains.

[0003] The production process of curtains requires automated equipment, including production lines and folding machines. Because the top of the curtain needs to be liningd, Oxford cloth needs to be sewn to the top of the curtain. However, the existing folding machine production line cannot fold the wide top fabric of the curtain and insert the lining at the same time, which requires manual processing and has a low degree of automation. Summary of the Invention

[0004] Therefore, it is necessary to provide a top interlayer fabric stitching device for curtain production, addressing the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sandwich fabric interlocking sewing device, comprising a fabric conveyor belt, wherein the tail end of the fabric conveyor belt is provided with a stretching machine and a motor-driven take-up roller.

A pressing belt driven to rotate by a drive guide wheel and a pressing guide wheel is provided at the lower end of the guide rod. The pressing belt and the guide rod are arranged to cross each other and form an intersection point.

[0007] When the fabric passes the support plate, the edge that needs to be folded hangs down through the guide rod, and the pressing belt presses the hanging fabric edge into the bottom of the fabric at the intersection point.

[0008] A lining mechanism is provided on one side of the fabric conveyor belt and at the station before the flanging mechanism. The lining mechanism includes a material tray with a material belt wound around it, an upper feeding roller and a lower feeding roller for feeding the material belt, and a cutter for cutting the material belt.

[0010] By setting the lining mechanism and the flanging mechanism, the fabric can be automatically folded and inserted into the lining, and then sewn by the tautener.

[0011] In one of the embodiments, the guide rod is provided with a bending part at the feeding end of the guide rod for guiding the end of the material belt, facilitating the entry of the material belt and playing a guiding role.

[0012] In one of the embodiments, the driving guide wheel and the edge pressing guide wheel are provided with two edge pressing belts, and the edge pressing guide wheel is provided outside the guide rod through a support, for folding the edge of the fabric.

[0013] In one of the embodiments, the lining mechanism further comprises a support, a first upper pressing plate and a first lower pressing plate fixed on the support and clamping the material belt, and the upper feeding roller and the lower feeding roller and the cutter are arranged at the rear end of the first upper pressing plate and the first lower pressing plate, the upper feeding roller is driven to rotate by the first driving motor, and when the feeding is completed, the cutter cuts off to complete the lining feeding of a single product.

[0014] In one of the embodiments, the upper feeding roller and the lower feeding roller are arranged at the upper end of the first upper pressing plate and the lower end of the first lower pressing plate respectively, the curved surface of the upper feeding roller and the lower feeding roller is provided with a uniform annular groove, the end surface of the first upper pressing plate and the first lower pressing plate is provided with a strip-shaped groove matched with the protrusions on both sides of the annular groove, and the protrusions of the upper feeding roller and the lower feeding roller are in contact with the upper and lower end surfaces of the material belt through the strip-shaped groove, so that the feeding of the material belt is stable.

[0015] In one of the embodiments, the tail end of the first upper pressing plate is fixedly provided with a cutter seat matched with the cutter, and the cutter is connected to the cutter seat by a cutter cylinder to cut off the material belt, so that the cutting effect is good.

[0016] In one of the embodiments, the rear end positions of the first upper pressing plate and the first lower pressing plate are further provided with a second upper pressing plate and a second lower pressing plate parallel thereto, the second lower pressing plate is provided with a pressing roller for conveying the material belt, for assisting feeding and preventing the tail of the material belt from hanging down after being cut off by the cutter, so that the end of the subsequent material belt cannot be sent to the next station.

[0017] In one of the embodiments, the pressing roller is arranged in a lifting manner through a lifting cylinder.

[0018] In one of the embodiments, the feeding ports of the first upper pressing plate and the first lower pressing plate, the second upper pressing plate and the second lower pressing plate are outwardly bent to form outwardly open ports, facilitating the entry of the material belt.

[0019] Compared with the prior art, the interlayer fabric interweaving and sewing equipment has the following advantages:

[0020] By arranging the flanging mechanism and the lining mechanism at the front work station of the tuck stitch machine, the flanging mechanism folds the edge of the fabric through the edge pressing belt, and at the same time, the lining mechanism synchronously conveys the material belt to the folded part of the fabric for interweaving, and is sewn by the tuck stitch machine, so that the problem of lining the top edge in the existing curtain production is solved, manual processing is not needed, complete automation is arranged, and the work efficiency is improved.
