Description

Technical Field

[0001] This invention relates to the field of sewing auxiliary equipment technology, and in particular to a multifunctional control cord-embedding device. Background Technology

[0002] The sewing of bed sheets and pillowcases is a field that requires a high level of craftsmanship and technical skill. Among them, sewing on the trim is a key process that plays an important role in enhancing the three-dimensionality and aesthetics of bed sheets and pillowcases.

[0003] In the process of sewing bed sheets and pillowcases, sewing the trim is an important step. To enhance the three-dimensionality and aesthetics of the edges, a cotton rope is usually inserted inside the trim to make it full and textured. During the sewing process, the worker first folds the trim in half and wraps it around the cotton rope. Then, they sew along the direction of the rope, embedding it into the trim. After the rope is embedded, the trim needs to be sewn onto the fabric. In this process, the worker folds the edge of the fabric in half and places it over the trim while sewing, ensuring that both the fabric edges and the trim containing the rope are taut.

[0004] The inventors discovered that the above-mentioned prior art has at least the following drawbacks: because during the sewing process, workers need to sew the trim and cotton rope together before sewing the trim onto the fabric, there is a problem of low production efficiency. Summary of the Invention

[0005] This application provides a multifunctional control rope-embedding device, which solves the technical problem of low production efficiency in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multifunctional control cord embedding device, including a base that can be fixed on the sewing machine table, one side of the base can fold the edge of the fabric in half, and a pull tube assembly is connected to the upper part of the other side of the base. The pull tube assembly is fixed to the upper part of the base through a connecting structure. The pull tube assembly includes a cord guide channel for folding the cord and a cotton cord guide tube connected to one side of the cord guide channel.

[0007] When using this device, fix the base and pull tube assembly in the appropriate position, and thread the strip and cotton rope through the strip assembly. At the same time, pass the edge of the fabric under the pull tube assembly and fold it twice, keeping one edge of the folded fabric above the edge of the strip. Then start the sewing machine to sew. In this way, the strip and the edge of the fabric are sewn together at the same time as the cotton rope is embedded in the strip, improving production efficiency.

[0008] Furthermore, the base includes a lower base plate and an upper base plate located above the lower base plate. One side of the lower base plate has an upwardly curved edge. One side of the upper base plate is a connecting end, which is connected to the upper edge of the lower base plate. The other side of the upper base plate is a free end, which is connected to the pull tube assembly through a connecting structure.

[0009] Furthermore, a folding plate is connected to the free end of the upper base plate, and the folding plate is located between the upper base plate and the lower base plate; one side of the folding plate is connected to the free end of the upper base plate, and the other side of the folding plate is folded back towards the free end of the upper base plate.

[0010] Furthermore, the connection structure includes a connecting seat fixed above the upper base plate and a connecting piece fixed to one side of the pull tube assembly. Both the connecting seat and the connecting piece are provided with strip grooves, and the strip grooves of the connecting seat and the connecting piece are connected and fixed by clamping bolts. Thus, when the pull tube assembly is relatively fixed to the upper base plate, there can be a gap between the bottom of the pull tube assembly and the surface of the lower base plate for the fabric to pass through. At the same time, the relative position of the pull tube assembly above the base can be adjusted by adjusting the positional relationship between the connecting seat and the connecting piece.

[0011] Furthermore, the base is connected to a fixed bracket, which includes a first bracket connected to the base and a second bracket connected to the first bracket. The second bracket is provided with a strip groove and is fixed to the sewing machine table through the strip groove and a clamping bolt. Thus, the position of the base can be adjusted for easy use.

[0012] Furthermore, the multifunctional cord-embedding device also includes a moving component, which includes a connecting part and a pressing edge part formed by two folds of a sheet metal. The pressing edge part is located between the upper and lower base plates of the base, and the opening of the pressing edge part after folding faces the side of the pull tube assembly. After the fabric is folded twice, its innermost edge will be located in the opening of the pressing edge part, thereby better maintaining the size of the fabric edge after folding.

[0013] Furthermore, it is provided with a strip groove extending along its length; correspondingly, the first bracket is also provided with a strip groove, and the strip groove of the connecting part is fixedly connected to the strip groove of the first bracket by a clamping bolt; the connecting part and the first bracket can be both relatively fixed and relatively movable; thus, the size of the fabric edge fold can be adjusted by adjusting the relatively fixed position of the connecting part and the first bracket.

[0014] Furthermore, a strip guide frame is fixed at the entrance end of the strip guide channel; in use, the strip is first inserted into the strip guide frame, which facilitates the advancement of the strip in the strip guide channel, so as to maintain the synchronization between the strip and the fabric.

[0015] As can be seen from the above technical solutions, the present invention has at least the following technical effects or advantages:

[0016] When using this device, fix the base and pull tube assembly in the appropriate position, and thread the strip and cotton rope through the strip assembly. At the same time, pass the edge of the fabric under the pull tube assembly and fold it twice, keeping one edge of the folded fabric above the edge of the strip. Then start the sewing machine to sew. In this way, the strip and the edge of the fabric are sewn together at the same time as the cotton rope is embedded in the strip, improving production efficiency. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0023] This invention discloses a multifunctional control cord-embedding device, which includes a base that can be fixed to a sewing machine table. One side of the base is used to fold the edge of the fabric in half, preparing the fabric. A pull tube assembly 1 is connected to the upper part of the other side of the base, and the pull tube assembly 1 is fixed to the upper part of the base by a connecting structure. The pull tube assembly 1 includes a cord guide channel 2 for folding the cord strip in half, and a cotton cord guide tube communicating with one side of the cord guide channel 2.

[0024] When using this device, first, the base and pull tube assembly 1 need to be fixed in a suitable position to ensure stability. Then, the strip and cotton rope are passed through the corresponding channels of the pull tube assembly 1. Next, the edge of the fabric is passed under the pull tube assembly 1 and folded twice, ensuring that one edge of the folded fabric is above the edge of the strip. Finally, the sewing machine is started to sew. With this device, the strip can be folded according to the contour of the channel inside the pull tube assembly 1, and the cotton rope is kept embedded in the folded strip. Since the strip is located below the folded edge of the fabric, starting the sewing machine allows for simultaneous sewing of the cotton rope and strip, and the strip and fabric edge, improving production efficiency.

[0025] like Figure 2 As shown, the base includes a lower base plate 4, which can be fixed to the sewing machine table. During use, the fabric is positioned above the lower base plate 4. One side of the lower base plate 4 is designed with an upward-curving edge, allowing for easy folding of the fabric edge. The base also includes an upper base plate 5, with one side serving as a connecting end that connects to the upward-curving upper edge of the lower base plate 4. The other side of the upper base plate 5 is a free end, which is connected to the pull tube assembly 1 via a connecting structure.

[0026] Specifically, in this embodiment, as shown in the figure, the free end of the upper base plate 5 is connected to the folding plate 6. The folding plate 6 is a component designed between the upper base plate 5 and the lower base plate 4. One side of the folding plate 6 is connected to the free end of the upper base plate 5 and folds back towards the connecting end of the upper base plate 5, while the other side of the folding plate 6 folds back towards the free end of the upper base plate 5. This allows the fabric edge to fold back twice when using this device, making it easier for the sewer to control the sewing speed and pressure. At the same time, it effectively prevents the fabric from slipping during sewing, improving the accuracy and quality of the sewing.

[0027] Furthermore, the connecting structure includes a connecting seat 7 located on the upper base plate 5 and a connecting piece 8 fixed to one side of the pull tube assembly 1. The connecting seat 7 and the connecting piece 8 are connected in a movable manner. Figure 2 As shown, the connecting seat 7 has a through hole for accommodating the connecting piece 8. The connecting piece 8 is L-shaped, with one end welded to one side of the pull tube assembly 1 and the other end inserted into the connecting seat 7. To allow the position of the pull tube assembly 1 to be adjusted, both the connecting seat 7 and the connecting piece 8 have slots, which are connected and fixed by clamping bolts. Thus, when the pull tube assembly 1 is fixed relative to the upper base plate 5, a gap exists between the bottom of the pull tube assembly 1 and the surface of the lower base plate 4 for the fabric to pass through. Furthermore, by adjusting the positional relationship between the connecting seat 7 and the connecting piece 8, the relative position of the pull tube assembly 1 above the base can be adjusted.

[0028] In this embodiment, the base is connected to a fixed bracket, which includes a first bracket 9 and a second bracket 10. One end of the first bracket 9 is connected to the base, and the other end is connected to the second bracket 10. The second bracket 10 can be fixed to the sewing machine table. The second bracket 10 also has a slot and is fixed to the sewing machine table via the slot and a clamping bolt. Therefore, the position of the base can be adjusted by loosening the clamping bolt of the second bracket 10 for convenient use.

[0029] In this embodiment, the multifunctional cord-embedding device further includes a moving component. For example... Figure 3 As shown, the moving assembly includes a connecting part 11 and a pressing edge part 12. The connecting part 11 connects the moving assembly to the fixed bracket, and the pressing edge part 12 serves to press the edge. When the moving assembly is engaged with the base, the pressing edge part 12 is located between the upper base plate 5 and the lower base plate 4 of the base, with the opening of the pressing edge part 12 after folding facing the pull tube assembly 1. In this way, after the fabric is folded twice, its innermost edge is located within the opening of the pressing edge part 12, better maintaining the dimensions of the fabric after the edge is folded back.

[0030] The connecting part 11 is a strip plate with a groove extending along its length; correspondingly, the first support 9 also has a groove, and the groove of the connecting part 11 and the groove of the first support 9 are fixedly connected by clamping bolts. The connecting part 11 and the first support 9 can be both fixed and movable relative to each other; thus, the size of the fabric edge fold can be adjusted by adjusting the relative fixed position of the connecting part 11 and the first support 9. It should be understood that a scale can also be installed above the upper base plate 5.

[0031] In this embodiment, the pull tube assembly 1 includes a strip guide channel 2 and a cotton rope guide channel 3, with the cotton rope guide channel 3 communicating with the strip guide channel 2. This allows the cotton rope to be wrapped within the strip while it is folded in half. Furthermore, a strip traction frame 13 is fixed to the entrance end of the strip traction channel. During use, the strip is first inserted into the strip traction frame 13, which facilitates the advancement of the strip within the strip guide channel 2, maintaining synchronization between the strip and the fabric.
