Description

Technical Field

[0001] This invention belongs to the field of keyhole device technology, and relates to a keyhole device for a polo shirt. Background Technology

[0002] Traditional polo shirts have three to four buttonholes, and the buttonholes at the collar are usually angled or at a 90-degree angle to the buttonholes below. In existing technology, buttonholes are typically manually positioned and then sewn using a buttonhole machine. For buttonholes with different orientations, manual rotation is required, which places higher demands on workers and is still prone to errors, leading to higher scrap rates and difficulty in reducing processing costs. To address this issue, Chinese patent number "202320199795.8" discloses a buttonhole device for clothing. It includes a buttonhole machine, a garment with multiple buttonholes in different orientations, a worktable, a tray, a fixing mechanism, a moving mechanism, a rotating mechanism, a detection mechanism, and a control mechanism. The garment is fixed to the tray, and the buttonhole machine sews the buttonholes. When the orientation of one buttonhole changes, the control mechanism controls the rotating mechanism to rotate the tray, and then controls the moving mechanism to move the tray, thus moving the next buttonhole to the accurate sewing position. If the orientation of the next buttonhole remains unchanged, the control mechanism controls the moving mechanism to move the tray, thereby automatically positioning the buttonholes of the garment in the correct position. The above structure takes into account buttonholes in different directions. However, there are differences between men's and women's buttonholes on polo shirts. Men's polo shirts have buttonholes on the right side and buttons on the left side, while women's polo shirts have buttonholes on the left side and buttons on the right side. The buttonhole designs of men's and women's polo shirts are mirror images of each other. The above structure cannot meet the production needs of both men's and women's polo shirts at the same time, and its applicability is limited. If it is necessary to produce both men's and women's polo shirts at the same time, two sets of equipment are required, which increases the production cost. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a buttonhole device for polo shirts that simultaneously meets the buttonhole sewing requirements of both men's and women's polo shirts.

[0004] The objective of this invention can be achieved through the following technical solution: A buttonhole device for a polo shirt, comprising a buttonhole machine, wherein the garment has multiple buttonholes in different directions, and further comprising a worktable, a tray, a fixing mechanism, a first moving mechanism, a second moving mechanism, and a rotating mechanism.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-3As shown, this polo shirt buttonhole device includes a buttonhole machine 1, a garment with multiple buttonholes facing different directions, a worktable 2, a tray 3, a fixing mechanism 4, a first moving mechanism 5, a second moving mechanism 6, and a rotating mechanism 7. The tray 3 is positioned above the worktable 2 to hold the garment, and the fixing mechanism 4 is positioned on the tray 3 to secure the garment. The first moving mechanism 5 is located at the bottom of the tray 3 and above the worktable 2, and it drives the tray 3 to move laterally relative to the worktable 2. The tray 3 is connected to the rotating mechanism 7 via the first moving mechanism 5, and the rotating mechanism 7 is connected to the second moving mechanism 6. The rotating mechanism 7 causes the tray 3 and the first moving mechanism 5 to rotate, and the second moving mechanism 6 causes the rotating mechanism 7, the tray 3, and the first moving mechanism 5 to move back and forth. The buttonhole machine 1 is positioned on the worktable to sew the buttonholes of the garment. The sewing process of the buttonhole machine 1 is existing technology. Figure 1 The image only shows the casing of the buttonhole machine 1, and is only used to illustrate the installation position of the buttonhole machine 1.

[0020] In the above technical solution: the two sides of the tray 3 are inclined relative to each other to form two guide slopes 31. The guide slopes 31 play a guiding role in the process of putting the clothes on the tray 3, which is convenient for putting on women's polo shirts with small necklines. The tray 3 has a sewing hole 32 in the middle. The sewing holes 32 are arranged symmetrically on the left and right. The sewing holes 32 include a right oblique sewing hole, a left oblique sewing hole, and a straight sewing hole located between the right oblique sewing hole and the left oblique sewing hole.

[0021] In the above technical solution: the first moving mechanism 5 includes a first moving cylinder 51, and the support plate 3 is fixed to the piston rod of the first moving cylinder 51. The piston rod of the first moving cylinder 51 drives the support plate 3 to move laterally. The bottom of the first moving cylinder 51 is provided with a cylinder fixing seat 52, and the bottom of the cylinder fixing seat 52 is provided with a connecting block 53. A roller 54 is fixed to the bottom of the connecting block 53. The bottom of the cylinder fixing seat 52 is provided with an elongated mounting hole 55, through which screws pass and are fixed to the connecting block 53. The roller 54 contacts the surface of the worktable 2, guiding the movement of the first moving mechanism 5 and the support plate 3 relative to the worktable 2. The elongated mounting hole 55 facilitates the adjustment of the mounting positions of the connecting block 53 and the roller 54, ensuring that the roller 54 always contacts the surface of the worktable 2.

[0022] In the above technical solution: a frame 8 is provided below the workbench 2, and the workbench 2 is fixed to the top of the frame 8. The second moving mechanism 6 includes a moving motor 61, a moving housing 62, a lead screw 63, and a moving plate 65. The moving housing 62 is fixed to the frame 8, and the moving motor 61 is fixed to the end of the moving housing 62. The output end of the moving motor 61 is connected to the lead screw 63, and a moving nut 64 is fitted on the lead screw 63. A moving slide rail 66 is also fixed on the frame 8, and a moving slider 67 slides on the moving slide rail 66. The two ends of the bottom of the moving plate 65 are respectively fixed to the top of the moving nut 64 and the moving slider 67. The moving motor 61 drives the lead screw 63 to rotate, and the moving nut 64 converts the rotational motion of the lead screw 63 into the back-and-forth movement of the moving plate 65. The moving slider 67 and the moving slide rail 66 guide the movement of the moving plate 65 and also support the moving plate 65, distributing the force on the moving plate 65.

[0023] In the above technical solution: the rotating mechanism 7 includes a rotating motor 71, which is fixed to the bottom of the moving plate 65, connecting the rotating mechanism 7 to the second moving mechanism 6. The output axis of the rotating motor 71 passes through the moving plate 65 and is fixed with a rotating connecting seat 72. The top of the rotating connecting seat 72 extends upward and is fixed to the cylinder fixing seat 52. The worktable 2 has a moving opening 21 for the rotating connecting seat 72 to pass through and move relative to the worktable 2. This connects the first moving mechanism 5 to the rotating mechanism 7. The rotating connecting seat 72 and the roller 54 are located at opposite ends of the cylinder fixing seat 52, ensuring the balance of the first moving mechanism 5 and the support plate 3 during movement.

[0024] In the above technical solution: the fixing mechanism 4 includes two sets of first fixing components and a second fixing component located between the two sets of first fixing components. The two sets of first fixing components are located on the sides of the right oblique sewing hole and the left oblique sewing hole, respectively, and the second fixing component is located on the side of the straight sewing hole. The first fixing components fix the garment to the support plate 3, and the second fixing components support the garment located above the sewing through hole 32. The first fixing component includes a fixing base plate 41, a first fixing cylinder 42, a hinge block 43, and a pressure plate 44. The fixing base plate 41 is fixed to the support plate 3, the first fixing cylinder 42 is fixed to the fixing base plate 41, the hinge block 43 is hinged to the end of the fixing base plate 41, and a hinge connecting rod 45 is fixed to the piston rod of the first fixing cylinder 42. The hinge connecting rod 45 is hinged to the hinge block 43. The pressure plate 44 is fixed to the hinge block 43, and a serrated contact surface is formed on the pressure plate 44. The piston rod of the first fixed cylinder 42 extends or shortens, causing the hinge block 43 and the pressure plate 44 to rotate, so that the pressure plate 44 presses down to fix the clothes or lifts up to loosen the clothes. The contact surface of the pressure plate 44 is in close contact with the clothes, and the serrated contact surface increases the friction between the pressure plate 44 and the clothes.

[0025] In the above technical solution: the second fixing component includes a second fixing cylinder 46 and a support plate 47. The second fixing cylinder 46 is fixed on the support plate 3. A movable connecting plate 48 is fixed on the piston rod of the second fixing cylinder 46. The support plate 47 has several elongated pressure plate fixing holes 49. Screws pass through the pressure plate fixing holes 49 and are fixed on the movable connecting plate 48. The end of the support plate 47 is bent downward in a Z-shape to form a support platform 410. The neckline of the garment is spread out above the sewing through hole 32, and the middle of the neckline of the garment rests on the support platform 410, providing support for the garment, making the garment flatter, ensuring the neatness and aesthetics of the sewn buttonholes, and preventing the garment from sagging excessively due to gravity during sewing, which would affect the sewing process.

[0026] The working process of this invention is as follows: Figure 1 As shown, the sewing needle of the buttonhole machine 1 is positioned above the right-angled sewing hole. At this point, the sewn buttonhole is on the right side, for men's polo shirt buttonholes: First, the buttonhole at the collar is sewn. Simultaneously, the second moving mechanism 6 drives the support plate 3 to move intermittently, shaping the buttonhole at the collar. Then, the rotating mechanism 7 drives the support plate 2 to rotate 90° or 105° to the right rear (defined). Figure 1 (The front of this application is shown. The rotation angle can be flexibly adjusted according to the tilt of the buttonhole at the collar.) The second moving mechanism 6 drives the support plate to move backward so that other buttonholes can be moved to the correct preset position and sewn by the buttonhole machine, so that other buttonholes are formed in sequence.

[0027] When it is necessary to sew buttonholes on a women's polo shirt, the first moving mechanism 5 moves the support plate 3 to the right so that the sewing needle of the buttonhole machine 1 is above the left-slanted sewing hole. After the buttonhole at the collar is sewn, the rotating mechanism 7 moves the support plate 3 to the right and rear by 90° or 105°. The second moving mechanism 6 moves the support plate 3 forward so that the other buttonholes are moved to the correct preset position, thus completing the sewing of the buttonholes on the women's polo shirt.

[0028] This polo shirt buttonhole device uses a first moving mechanism 5 to drive the support plate 3 to move laterally, simultaneously meeting the buttonhole sewing needs of both men's and women's polo shirts. Its ingenious and reliable structure has a wide range of applications. Rollers 54 guide the movement of the first moving mechanism 5 and the support plate 3 relative to the worktable 2. The rollers 54 and the rotating connecting seat 72 are located at opposite ends of the cylinder fixing seat 52, ensuring balance during movement. The center of the garment's neckline rests on the support platform 410 of the second fixing component, providing support and ensuring a smoother garment. This guarantees the neatness and aesthetics of the sewn buttonholes and prevents the garment from excessively sagging due to gravity during sewing, which would affect the sewing process.
