[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] Reference Figures 1 to 10 An embodiment of the present invention provides a manufacturing device for a sutured pocket spring, comprising a support assembly 100, a spring conveying mechanism 200, a first sewing mechanism 300, and a second sewing mechanism 400, wherein the support assembly 100 is used to support a folded cloth 10; the first sewing mechanism 300 is used to sew a side opening formed by the folded cloth 10 to close the side opening, and the first sewing mechanism 300 sews a first stitch 510, and the first stitch 510 is parallel to the conveying direction (i.e., the longitudinal direction) of the cloth 10; the spring conveying mechanism 200 is used to convey the spring 20 into the interior of the folded cloth 10; the second sewing mechanism 400 is used to sew the cloth 10 to form a plurality of spaced cloth pockets 30 for accommodating the spring 20, and the second sewing mechanism 400 sews a plurality of second stitches 520 spaced apart and distributed along the longitudinal direction, and each second stitch 520 is arranged transversely on the cloth 10.

[0044] It can be understood that the structure of the sewing mechanism is common knowledge for technicians in the textile field. The specific structure of the first sewing mechanism 300 and the second sewing mechanism 400 will not be repeated here. The first sewing mechanism 300 and the second sewing mechanism 400 of this embodiment have an automatic thread breaking function, and the sutures can be cut by a cutter or scissors.

[0045] The manufacturing apparatus for sutured pocket springs of this embodiment folds a fabric 10 in half and supports it on a support assembly 100. A spring conveying mechanism 200 conveys a spring 20 into the folded fabric 10. The fabric 10 is then sewn by a sewing mechanism. A first sewing mechanism 300 seals the side opening formed by the folded fabric 10, forming a first stitch 510 at the edge. A second sewing mechanism 400 sews the fabric 10 to form a second stitch 520, forming a plurality of spaced pockets 30 each containing a spring 20. Each pocket 30 contains a spring 20, forming a sutured pocket spring. Multiple connected sutured pocket springs form a pocket spring string. Compared to traditional sutured pocket spring production methods that require manual sewing, this apparatus improves sewing efficiency, thereby increasing the production efficiency of sutured pocket springs.

[0046] In this embodiment, the manufacturing apparatus for stitched pocket springs includes a first drive mechanism 600, which is used to clamp and pull the fabric 10 for transport. The first drive mechanism 600 uses a clamping method to drive the fabric 10 for transport. Specifically, the first drive mechanism 600 may include two clamping plates 610 disposed above and below. The two clamping plates 610 can move toward each other to clamp the fabric 10 and then pull the fabric 10 forward.

[0047] In some embodiments, the support assembly 100 specifically includes two positioning plates 110 spaced apart and arranged relative to each other and capable of relative movement and adjustment. The positioning plates 110 extend along the conveying direction of the fabric 10. The folded fabric 10 is wrapped around the two positioning plates 110. The positioning plates 110 are convex outwardly and can shape the two sides of the folded fabric 10 to facilitate sewing by the first sewing mechanism 300. The relative movement of the two positioning plates 110 can adjust the lateral width of the folded fabric 10.

[0048] In some embodiments, there is at least one second sewing mechanism 400 , and the second seam 520 formed by each second sewing mechanism 400 spans the folded fabric 10 .

[0049] It is understandable that, as required, the second sewing mechanism 400 is set as one, referring to Figure 3 When sewing, the second sewing mechanism 400 moves across the folded cloth 10, so that the single second stitching line 520 formed spans the entire folded cloth 10, completing one stitching; for the next stitching, the cloth 10 moves forward by the distance of a single cloth bag 30, and the second sewing mechanism 400 can move across the folded cloth 10 in the opposite direction to perform reverse stitching, or first move in the opposite direction to reset to the initial position, and then move forward across the folded cloth 10 to perform forward stitching; after multiple stitching, a pocket spring string is finally formed, refer to Figure 6 .

[0050] As required, the second sewing mechanism 400 is provided in plurality, referring to Figure 4 , multiple second sewing mechanisms 400 are arranged on the same side, and multiple equidistant second sewing mechanisms 400 are continuously arranged at a distance of each stitching pocket spring, or multiple equidistant second sewing mechanisms 400 are arranged at a distance of multiple stitching pocket springs. The multiple second sewing mechanisms 400 can act simultaneously, and multiple second stitches 520 can be formed by one sewing. Each time the cloth 10 moves forward, it moves the distance of a corresponding number of cloth bags 30, thereby greatly improving production efficiency.

[0051] In some other embodiments, there are at least two second sewing mechanisms 400, and each second sewing mechanism 400 is staggeredly arranged on the left and right sides of the folded cloth 10. Figure 1 and Figure 5 The second stitches 520 formed by the second sewing mechanisms 400 half span the folded fabric 10, referring to Figure 7 , the two half-span second stitches 520 in the same straight line direction are used to space the cloth bag 30. In this way, each time a second stitch 520 is sewn to form a second stitch 520, a reciprocating movement from the outer side to the middle of the folded cloth 10 is required. Specifically, refer to Figure 7 The second suture 520 is V-shaped or Y-shaped, and the second sewing mechanism 400 is reset to the initial position after each sewing action.

[0052] It is understandable that the width of the half span is not necessarily half of the transverse width of the folded fabric 10, and may be slightly smaller than half of the width, that is, there may be a certain gap between the two half-span second seams 520 in the same straight direction.

[0053] It can be understood that, as needed, the second sewing mechanisms 400 are set to an even number greater than two, and the second sewing mechanisms 400 are staggered. Multiple second sewing mechanisms 400 can operate simultaneously, and multiple second sutures 520 can be formed in one sewing operation, thereby greatly improving production efficiency.

[0054] In some embodiments, the manufacturing equipment of the sutured pocket spring includes a second driving mechanism, which is used to drive the second sewing mechanism 400 to move back and forth along the conveying direction of the fabric 10, so that the second sewing mechanism 400 can move and sew as the fabric 10 is conveyed forward during the sewing process. In this way, the fabric 10 can be continuously moved and conveyed, reducing the stop time and improving production efficiency.

[0055] In some embodiments, the folded cloth 10 is wrapped around two positioning plates 110, and an inner space 40 is formed between the two positioning plates 110 and the folded cloth 10. Figure 9 and Figure 10The upstream end (rear end) of the folded fabric 10 is turned toward the inner space 40 so that the inner surface and the outer surface of the fabric 10 are exchanged, and the fabric 10 is turned over. After turning over, the edge sealing of the fabric 10 at the first seam 510 is hidden inside, so that the position of the outer edge sealing of the fabric 10 is more flat and beautiful. Figure 8 The turned cloth 10 is pulled forward by the first driving mechanism 600 .

[0056] It is understandable that a turning mechanism may be provided to turn the cloth 10 over.

[0057] In some embodiments, the spring conveying mechanism 200 is arranged upstream of the folded cloth 10. The spring conveying mechanism 200 includes two conveyor belts 210 arranged opposite to each other up and down. The spring 20 is vertically placed between the two conveyor belts 210. The two conveyor belts 210 clamp and compress the spring 20 and drive the spring 20 to be conveyed.

[0058] In some embodiments, the manufacturing equipment of the sutured pocket spring includes a spring shaping assembly 800, which is arranged downstream of the support assembly 100. The spring shaping assembly 800 includes two support members 810 arranged opposite to each other up and down, so that the cloth 10 wraps the compressed spring 20 and passes through the gap between the two support members 810 to maintain the vertical compression state of the spring 20. The spring 20 moves forward as the cloth 10 is conveyed forward.

[0059] In existing bagged spring manufacturing equipment, the springs are placed and transported horizontally; in this embodiment, the spring shaping component 800 is used to keep the spring 20 in a vertically compressed state to prevent the spring 20 from stretching, so that the fabric 10 can be kept flat, thereby facilitating the sewing action of the first sewing mechanism 300 and the second sewing mechanism 400.

[0060] In some embodiments, there are multiple spring shaping assemblies 800, and the multiple spring shaping assemblies 800 are arranged at intervals along the conveying direction of the fabric 10. The second sewing mechanism 400 is arranged between two adjacent spring shaping assemblies 800, and there is a gap between the two adjacent spring shaping assemblies 800 to provide space for the second sewing mechanism 400 to sew and form the second seam 520.

[0061] Specifically, the upstream end (i.e., rear end) of the support member 810 is tilted, and the upstream ends (i.e., rear ends) of the upper and lower support members 810 are formed into a shape with a gradually decreasing opening size, i.e., a bell-mouth shape, so that the spring 20 is gradually compressed and inserted between the two support members 810. Furthermore, the front end of the support member 810 is also tilted, and the front end of the upper and lower support members 810 is formed into a shape with a gradually increasing opening size, so that the installation of the support member 810 is facilitated, and it can be placed and installed in the forward and reverse directions.

[0062] In some embodiments, the manufacturing equipment of the sutured pocket spring includes a shift block 900 arranged downstream of the spring shaping assembly 800. The shift block 900 can move back and forth in the left and right directions to shift the spring 20 in the cloth bag 30, so that the vertically compressed spring 20 stretches laterally to fill the cloth bag 30. After the spring 20 stretches laterally, the cloth bag 30 is stretched outward and expanded, changing from a flat structure to a roughly cylindrical shape.

[0063] The first driving mechanism 600 is arranged at the downstream position of the shifting block 900, and the two clamping plates 610 clamp the second seam 520 between the two adjacent cloth bags 30 after the spring 20 is stretched. In this way, the clamping can be made firmer and the clamping plates 610 can be prevented from slipping.

[0064] An embodiment of the present invention further provides a method for manufacturing a suture pocket spring, wherein the suture pocket spring is manufactured using the above-mentioned suture pocket spring manufacturing equipment, and the method comprises the following steps:

[0065] Fold the cloth 10 in half and wrap it around the two positioning plates 110 to position the cloth 10;

[0066] The first sewing mechanism 300 sews the side opening of the fabric 10 to form a first stitch 510 to seal the side opening;

[0067] The folded cloth 10 is turned inward so that the inner and outer surfaces of the cloth 10 are swapped. The first stitching thread 510 is hidden inside the cloth 10. The turned cloth 10 passes between the upper and lower support members 810 of the spring shaping assembly 800. The first driving mechanism 600 clamps the cloth 10 and transports it forward.

[0068] The spring conveying mechanism 200 compresses and conveys the spring 20 into the folded cloth 10. Under the action of the multiple spring shaping components 800, the spring 20 remains in a vertically compressed state and is conveyed along with the cloth 10.

[0069] The second sewing mechanism 400 sews the cloth 10 to form a plurality of spaced cloth pockets 30 for accommodating the springs 20;

[0070] The shifting block 900 shifts the spring 20 in the cloth bag 30 , causing the vertically compressed spring 20 to extend laterally to fill the cloth bag 30 .

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
