Description

Technical Field

[0001] This application relates to the technical field of garment production, and in particular to a high-precision sleeve attaching machine. Background Technology

[0002] In the current garment manufacturing industry, cuff sewing is one of the key processes in garment production, and its precision directly affects the appearance quality and wearing comfort of the clothing. As consumers' demands for garment quality increase, they have higher requirements for precision and efficiency in garment production. In recent years, automated cuff sewing equipment has gradually become more widespread, but there is still significant room for improvement in its precision and stability.

[0003] Currently, when sewing the cuffs, the cuff edge needs to be overlapped with the corresponding edge of the garment body and placed together. The overlapping part is then placed on the sewing machine, and the two are moved together while being sewn to complete the sleeve-attaching operation.

[0004] Regarding the aforementioned technologies, the inventors believe that during the sleeve-attaching process, the width of the sewn edge is affected by the operator's manual operation, and sometimes the sewing thread may shift, affecting the sewing accuracy and flatness of the cuff. Utility Model Content

[0005] To improve the sewing accuracy of the sleeve attaching process, this application provides a high-precision sleeve attaching machine.

[0006] The high-precision sleeve-fitting machine provided in this application adopts the following technical solution:

[0007] A high-precision sleeve attaching machine includes a worktable, a sewing machine, and a limiting assembly. The sewing machine is mounted on the top surface of the worktable, and an upper sleeve needle is vertically mounted on the sewing machine. An upper sleeve hole corresponding vertically to the upper sleeve needle is formed on the worktable. The limiting assembly includes a limiting plate, which includes a vertically mounted vertical plate and a horizontal plate mounted on the top edge of the vertical plate. Two limiting plates are provided on the top surface of the worktable, and the two limiting plates are respectively positioned on opposite sides of the upper sleeve hole. The vertical plates of the two limiting plates are coplanar, and the plane of the vertical plate is located on one side of the upper sleeve hole.

[0008] By adopting the above technical solution, when sewing the cuff and the garment body, the seam edges of the two are overlapped and aligned and placed between the horizontal plate and the worktable, so that the seam edge abuts against one side of the vertical plate. The limiting plate limits the width of the seam edge, and the width of the seam edge is equal to the distance between the upper armhole and the plane of the vertical plate. The fabric is moved while sewing, achieving precise sewing of the fabric. Through the cooperation of the worktable, sewing machine, and limiting components, the consistency of the seam edge width is controlled, which improves the sewing accuracy of the sleeve attachment process.

[0009] Optionally, two parallel sliding grooves are formed on the worktable. The length direction of the sliding grooves is perpendicular to the vertical plane where the vertical plate is located. The two sliding grooves correspond one-to-one with the two limiting plates. A slider is slidably disposed in the sliding groove. The two sliders correspond one-to-one with the two limiting plates. The limiting plates are disposed on the top surface of the sliders. A first adjusting member for adjusting the position of the sliders in the sliding grooves is provided on the worktable.

[0010] By adopting the above technical solution, the position of the slider in the groove can be adjusted to meet the needs of different widths of sewing edges, thereby adjusting the distance between the plane of the vertical plate and the upper sleeve hole and expanding the applicability of the device.

[0011] Optionally, a linkage plate is connected between the two sliders, and the first adjusting member is disposed on the linkage plate.

[0012] By adopting the above technical solution, the linkage plate enables synchronous adjustment of the positions of the two sliders in the slide groove, ensuring the consistency of the two limiting plates in the width of the limiting edge.

[0013] Optionally, the top surface of the slider is vertically provided with an insertion slot, the vertical plate is slidably inserted into the corresponding insertion slot, and the slider is provided with a second adjusting member for driving the vertical plate to move in the vertical direction.

[0014] By adopting the above technical solution, the length of the vertical plate extending from the slider can be adjusted using the second adjusting component for fabrics of different thicknesses, thereby adjusting the distance between the horizontal plate and the top surface of the slider and expanding the application range of the device.

[0015] Optionally, the vertical plate is provided with thickness scale lines along the vertical direction, and the worktable is provided with width scale lines along the direction parallel to the length direction of the slide.

[0016] By adopting the above technical solution, the setting of thickness and width scale lines facilitates operators to accurately adjust the width of the limit edge and the distance between the horizontal plate and the slider.

[0017] Optionally, a guide ramp is connected to the side of the horizontal plate away from the vertical plate, and the distance between the guide ramp and the top surface of the workbench increases in the direction away from the horizontal plate.

[0018] By adopting the above technical solution, the guide plate is set at the edge of the horizontal plate, making it easier for the fabric to be inserted between the horizontal plate and the worktable.

[0019] Optionally, a clamping plate is horizontally arranged between the horizontal plate and the slider, and a clamping spring is arranged between the top surface of the clamping plate and the bottom surface of the horizontal plate.

[0020] By adopting the above technical solution, the pressing plate and the fabric are pressed together, reducing the possibility of the fabric coming out of the limiting plate.

[0021] Optionally, the horizontal plate is provided with a contact roller, and the rotation axis of the contact roller is arranged parallel to the slide groove.

[0022] By adopting the above technical solution, the contact rollers come into contact with the stacked fabric, making it easier for the user to push the fabric between the limiting plate and the worktable during sewing.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By cooperating with the worktable, sewing machine and limiting components, the consistency of the seam edge width is controlled, which improves the sewing accuracy of the sleeve attaching process;

[0025] 2. To accommodate different widths of sewing edges, the position of the slider in the groove can be adjusted to regulate the distance between the plane of the vertical plate and the upper armhole, thus expanding the applicability of the device;

[0026] 3. The contact rollers abut against the stacked fabric, making it easier for the user to move the fabric between the limit plate and the worktable while sewing. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be further described in detail below. Embodiments of this application provide a high-precision sleeve attaching machine, which improves the sewing accuracy of the sleeve attaching process.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 A high-precision sleeve attaching machine includes a worktable 1, a sewing machine 2, and a limiting component 3. The sewing machine 2 is disposed on the top surface of the worktable 1, and an upper sleeve needle 21 for sewing the cuff is vertically disposed on the sewing machine 2. The worktable 1 is provided with an upper sleeve hole 102 corresponding to the upper sleeve needle 21 in the vertical direction.

[0035] Reference Figure 1 and Figure 2 Two parallel sliding grooves 101 are arranged on the top surface of the worktable 1, and the two sliding grooves 101 are respectively arranged on opposite sides of the upper sleeve hole 102. A slider 4 is slidably arranged in each sliding groove 101. A limiting component 3 is arranged on the worktable 1, and the limiting component 3 includes a limiting plate 31 and a guide inclined plate 32. A vertical plate 311 is provided on each slider 4, and the top surface of the slider 4 has a vertical insertion groove 41. The vertical plane of the insertion groove 41 is perpendicular to the length direction of the sliding groove 101, and the bottom end of the vertical plate 311 is slidably inserted into the corresponding insertion groove 41. A horizontal plate 312 is horizontally connected to one side of the top edge of the vertical plate 311. The side of the horizontal plate 312 away from the vertical plate 311 is connected to the guide inclined plate 32. The distance between the guide inclined plate 32 and the top surface of the slider 4 gradually increases along the direction away from the horizontal plate 312. The two vertical plates 311 are arranged in the same plane, and the vertical plane containing the two vertical plates 311 is located on one side of the upper armhole 102.

[0036] Reference Figure 2A connecting plate 5 is horizontally connected to the side of the vertical plate 311 away from the horizontal plate 312. A first adjusting screw 6 is vertically rotatably mounted on the top surface of the slider 4, and the first adjusting screw 6 is threadedly connected to the connecting plate 5. Thickness scale lines 313 are set along the vertical direction on the side of the vertical plate 311 away from the horizontal plate 312. A linkage plate 7 is connected between the top surfaces of the two sliders 4. The bottom surface of the linkage plate 7 is slidably attached to the top surface of the worktable 1. An adjusting plate 8 is vertically connected to the top surface of the linkage plate 7. A second adjusting screw 9 is horizontally threadedly connected to the adjusting plate 8. The second adjusting screw 9 is threadedly connected to the adjusting plate 8. The setting direction of the second adjusting screw 9 is parallel to the length direction of the slide groove 101. A mounting plate 10 is rotatably mounted at both ends of the second adjusting screw 9. The mounting plate 10 is fixedly connected to the top surface of the worktable 1. Width scale lines 103 are set along the length direction of the slide groove 101 on the top surface of the worktable 1. A pressing plate 11 is horizontally arranged between the slider 4 and the horizontal plate 312, and a pressing spring 12 is connected between the pressing plate 11 and the horizontal plate 312.

[0037] Reference Figure 1 and Figure 2 When sewing the sleeve, the edge of the sleeve is aligned with the corresponding edge of the garment body and overlapped. The overlapping fabric is inserted between the pressure plate 11 and the slider 4, with the edge of the fabric abutting against one side of the vertical plate 311. The guide slant 32 facilitates the operator's insertion of the fabric. The pressure plate 11, under the action of the pressure spring 12, presses the fabric firmly against the surface of the worktable 1, reducing the possibility of the fabric slipping out between the slider 4 and the horizontal plate 312 during sewing. The distance between the plane of the vertical plate 311 and the upper sleeve hole 102 is equal to the width of the sewing edge. The operator pushes the fabric while sewing against the vertical plate 311, thus limiting the width of the sewing edge and helping to improve the accuracy of the sleeve-attaching process and the flatness of the garment production.

[0038] Reference Figure 2 For fabrics of different thicknesses, turning the first adjusting screw 6 causes the horizontal plate 312 to move vertically under the limiting action of the insertion slot 41 and the driving action of the first adjusting screw 6, thereby adjusting the distance between the horizontal plate 312 and the slider 4. For different sewing edge width requirements, turning the second adjusting screw 9 causes the slider 4 to move within the slide groove 101 under the driving action of the second adjusting screw 9 and the limiting action of the slide groove 101, thereby adjusting the sewing edge width and expanding the applicability of the device. The width scale line 103 and the thickness scale line 313 facilitate precise adjustments by the operator according to actual needs.

[0039] The implementation principle of a high-precision sleeve attaching machine in Embodiment 1 of this application is as follows: When sewing the sleeve, the edge of the sleeve is aligned with the corresponding edge of the garment body and overlapped. The overlapped fabric is inserted between the pressing plate 11 and the slider 4, and the edge of the fabric abuts against one side of the vertical plate 311. The vertical plate 311 limits the width of the sewing edge, which helps to improve the accuracy of the sleeve attaching process.

[0040] For fabrics of different thicknesses, turning the first adjusting screw 6 adjusts the distance between the horizontal plate 312 and the slider 4. For different sewing edge width requirements, turning the second adjusting screw 9 adjusts the sewing edge width, expanding the applicability of the device.

[0041] Example 2

[0042] Reference Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 is that a contact roller 13 is rotatably provided on the horizontal plate 312, and the rotation axis of the contact roller 13 is parallel to the length direction of the slide groove 101.

[0043] Reference Figure 3 and Figure 4 During sewing, the contact roller 13 abuts against the overlapping fabric, making it easier for the operator to push the fabric to sew.

[0044] The implementation principle of a high-precision sleeve sewing machine in Embodiment 2 of this application is as follows: the setting of the contact roller 13 facilitates the operator to push the fabric for sewing.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
