Description

Technical Field

[0001] This application belongs to the field of edge binding equipment technology, and in particular relates to an edge binding device for combining lace and woven fabric. Background Technology

[0002] In garment processing, the edges of fabric are typically bound using a binding strip. To improve binding quality, existing binding equipment often uses a binding head to assist in the binding process. For example, Chinese patent number 201821135033.7 discloses an adjustable binding head to assist operators in binding and sewing. It includes a base, a binding tube, and a guide rod. A pressing adjustment component is located at the end of the binding tube away from the guide rod. The outlet of the binding tube faces the pressing adjustment component. The pressing adjustment component includes an upper pressing component that can move up and down and a lower pressing component fixed to the base. An adjusting screw is fixedly connected to the base, passing through the upper pressing component. A compression spring for supporting the upper pressing component is sleeved on the adjusting screw. An adjusting knob is also threaded onto the adjusting screw, located above the upper pressing component and abutting against its upper surface. In this solution, by adding a pressing adjustment component at the outlet of the binding tube, the binding fabric can be made to fit snugly against the fabric as it enters the sewing opening.

[0003] The above-disclosed solution is only applicable to assisting in the binding of a single fabric. When binding multiple fabrics together (e.g., binding lace and woven fabric together), the lack of a structure to press each fabric and the different elasticity of each fabric lead to length variation errors in the binding of multiple fabrics (e.g., binding lace and woven fabric together), which reduces the aesthetics and processing quality, thus limiting its applicability. Utility Model Content

[0004] In view of this, the main objective of this application is to provide an edge binding device that can ensure that there will be no error due to length changes when lace and woven fabric are joined together for edge binding.

[0023] To make the objectives, technical solutions, design methods, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings, provides specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0024] It should be noted that this application is mainly applicable to the binding of lace and woven fabrics. This application mainly addresses the defects of the existing lint-head device and proposes a binding device with a lint-head structure for binding lace and woven fabrics. The specific implementation method is as follows:

[0025] This application relates to a binding device for combining lace and woven fabrics, see reference. Figures 1-3 As shown, the system includes a sewing machine body 10, a mounting platform 11, an edging unit 12, and a pulling unit 16. The edging unit 12 is mounted on the mounting platform 11 and positioned in the sewing direction of the sewing machine body 10. The edging unit 12 includes a vertical plate 13, the width of which gradually decreases from the pulling unit towards the sewing machine body 10. A first fabric pressing assembly 14, a second fabric pressing assembly 15, and an edging structure are mounted on the vertical plate 13. The first fabric pressing component 14 is used to convey and press the woven fabric, and the second fabric pressing component 15 is used to convey and press the lace fabric. The binding structure is used to bind the edges of the fabrics conveyed by the first fabric pressing component 14 and the second fabric pressing component 15. The pulling unit 16 is installed on the mounting table and set in the sewing direction of the sewing machine body 10. The pulling unit 16 is used to pull the lace fabric and the woven fabric, and then the sewing machine body 10 is used to sew and bind the edges.

[0026] In the above, the pulling unit includes a pulling rail 32 and a pulling member 33, the pulling member 33 being slidably connected to the pulling rail 32; the pulling member 33 includes an upper clamping block 34 and a lower clamping block 35, one end of the upper clamping block 34 being hinged to the lower clamping block 35, the other end of the upper clamping block 34 being provided with a fastening bolt 36, and the other end of the upper clamping block 34 being threadedly connected to the lower clamping block 35 through the fastening bolt 36.

[0027] In the above, the woven fabric and the lace fabric are pressed simultaneously by the first fabric pressing component 14 and the second fabric pressing component 15 to ensure that the woven fabric and the lace fabric do not deviate during the binding process, and to avoid errors caused by length changes due to different elasticity of the fabric, thereby improving the binding quality; at the same time, before binding the lace and woven fabric together, one end of the two fabrics needs to be pressed by the two fabric pressing components, and the other end of the two fabrics is pulled by the tensioning unit.

[0028] This application relates to a binding device for combining lace and woven fabrics, see reference. Figures 1-3As shown, the first fabric pressing assembly 14 includes a first guide plate 17 and a first pressing plate 18 mounted on the vertical plate 13. The first guide plate 17 is used to guide the woven fabric, and the first pressing plate 18 is located above the first guide plate 17 and presses the woven fabric. The second fabric pressing assembly 15 includes a second guide plate 19 and a second pressing plate 22. The top of the vertical plate 13 is provided with a flange 20 along the length of the vertical plate 13 on the side of the second guide plate 19. The flange 20 cooperates with the second guide plate 19 to form a guide channel 21 for the lace fabric to pass through. The second pressing plate 22 is mounted on the output end of the second guide plate 19 and presses both the lace fabric and the woven fabric simultaneously.

[0029] This application relates to a binding device for combining lace and woven fabrics, see reference. Figures 1-3 As shown, the second guide plate 19 is provided with a downwardly inclined arc surface 23 at the end near the second pressing plate 22. Correspondingly, the second pressing plate 22 is provided with a first arc portion 24a that cooperates with the arc surface 23 at the end near the second guide plate 19. The first arc portion 24a is inclined in the same direction as the arc surface 23.

[0030] Below the second pressing plate 22, there is a third guide plate 24 located on the output direction side of the first guide plate 17. A second arc portion 25 is provided between the third guide plate 24 and the first guide plate 17. The second arc portion 25 is set with the same specifications as the first arc portion 24a. The two ends of the second arc portion 25 are respectively transitionally fitted with the first guide plate 17 and the third guide plate 24.

[0031] In the above process, the lace fabric is placed in the guide channel 21. Since the output end of the second guide plate 19 and the input end of the second pressing plate 22 both have curved surfaces and form a height difference, the lightweight lace fabric can be tightened. The tightened lace fabric adheres to the woven fabric. Furthermore, since the first guide plate 17 and the third guide plate 24 are connected by the second arc 25, a height difference is formed between the first guide plate 17 and the third guide plate 24. Through the pressing of the second pressing plate 22, the woven fabric can be tightened and pressed. During the above process, the lace fabric and the woven fabric are tightened and pressed. When they are joined together for edge binding, there will be no positional movement, which effectively improves the edge binding quality.

[0032] Meanwhile, in the above, the first pressing plate 18 and the vertical plate 13 can be configured to be adjustable up and down to adjust the pressing gap between the first pressing plate 18 and the first guide plate 17.

[0033] This application relates to a binding device for combining lace and woven fabrics, see reference. Figures 1-3As shown, an adjusting rod 26 is connected to the top surface of the second pressing plate 22. The adjusting rod 26 extends upward and pierces the flange 20. An adjusting nut 27 is threadedly connected to the end of the adjusting rod 26 that pierces the flange 20. An elastic element 28 is sleeved on the outside of the adjusting rod 26. One end of the elastic element 28 abuts against the adjusting nut 27, and the other end of the elastic element 28 abuts against the top surface of the flange 20. The extension and retraction distance of the adjusting rod 26 can be controlled by the adjusting nut 27, so that the distance between the second pressing plate 22 and the third guide plate 24 can be adjusted to achieve the pressing degree of lace and woven fabric.

[0034] This application relates to a binding device for combining lace and woven fabrics, see reference. Figures 1-3 As shown, the binding structure includes a guide frame 29 connected to the vertical plate 13, and a binding feed channel 30 for binding is provided in the vertical plate 13; a U-shaped guide groove 31 is provided at the end of the vertical plate 13 near the sewing machine body 10, and the U-shaped guide groove 31 communicates with the binding feed channel 30; wherein, the guide frame 29 is S-shaped; the U-shaped guide groove makes the binding material concave inward, making the binding operation smoother.

[0035] In the above, the height of the vertical plate 13 gradually decreases to ensure that the fabric at the output end of the two fabric pressing components can be pressed by the second pressing plate 22 and the third guide plate 24, pressing the two fabrics at the same time to ensure that the pressed fabrics will not be of different lengths due to different materials, so that the two fabrics can be fitted together, making it convenient for the binding structure to perform binding operations on lace and woven fabrics.

[0036] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technological improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
