[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1:

[0019] like Figures 1-6As shown, this utility model discloses a button-attaching device for wool sweater processing, including a base plate 1 and a column 2 disposed on the base plate 1. A positioning plate 3 is disposed in the middle of the column 2, and a positioning hole 15 is disposed on the positioning plate 3. The positioning hole 15 is used to position the button. A top plate 4 is disposed on the top of the column 2, and a vertically downward first cylinder 5 is disposed on the top plate 4. A push rod 8 is disposed at the telescopic end of the first cylinder 5. The push rod 8 is located directly above the positioning hole 15 and cooperates with the positioning hole 15. A vertically upward second cylinder 6 is disposed on the base, and a positioning mold 7 is disposed at the telescopic end of the second cylinder 6. The positioning mold 7 is used to position the button and is located directly below the positioning hole 15.

[0020] The base plate 1 is fixed to the ground, and the column 2 extends upward. A positioning plate 3 is installed in the middle of the column 2. The positioning plate 3 is horizontally positioned, and a positioning hole 15 is provided in the middle of the positioning plate 3. The positioning hole 15 is designed according to the size of the upper button, and the button can be positioned within the positioning hole 15. A vertically upward second cylinder 6 is installed on the base plate 1. A positioning mold 7 is installed at the telescopic end of the second cylinder 6. The positioning mold 7 has a cavity for positioning the lower button, which can be provided according to actual needs. Since the positioning mold 7 is located directly below the positioning hole 15, the positioning and pressing of the two can be ensured to be stable and reliable in actual use. By setting the positioning mold 7 at the telescopic end of the second cylinder 6, the height of the positioning mold 7 can be adjusted during actual use. Under normal circumstances, the second cylinder 6 is in the retracted state. At this time, the positioning mold 7 and the positioning plate 3 are disengaged, with a large gap, which makes it easy to place the lower part of the button into the cavity of the positioning mold 7. Then, the corresponding position of the sweater is placed on the positioning mold 7. At this time, the button and the buttoning position of the sweater are accurately matched. The second cylinder 6 is activated, and the second cylinder 6 drives the positioning mold 7 to rise and fit against the positioning plate 3, so that the sweater and the lower part of the button are clamped between the positioning mold 7 and the positioning plate 3. The upper part of the button is placed in the positioning hole 15, and the first cylinder 5 is activated. The first cylinder 5 extends, and the push rod 8 at its end extends into the positioning hole 15, pressing the upper part of the button down until it is pressed against the lower part of the button on the sweater, realizing the buttoning work of the sweater. The operation is simple and convenient, and it can realize the positioning and buttoning of the sweater, greatly improving efficiency and improving the processing quality of the sweater.

[0021] Four recessed holes 16 are radially spaced on the inner wall of the positioning hole 15. The recessed holes 16 extend into the positioning plate 3. The recessed holes 16 are stepped holes. The recessed holes 16 near the positioning hole 15 are rectangular, and the recessed holes 16 away from the positioning hole 15 are circular. The diameter of the circular recessed hole 16 is larger than the side length of the rectangular recessed hole 16. A limiting post 17 is provided in the recessed hole 16. The portion of the limiting post 17 in the rectangular recessed hole 16 is cuboid, and the portion in the circular recessed hole 16 is cylindrical. A compression spring 18 is provided in the circular recessed hole 16 away from the positioning hole 15. The end of the compression spring 18 abuts against the cylindrical end of the limiting post 17. In the natural state, the end of the limiting post 17 is located in the positioning hole 15 to prevent the button from falling out of the positioning hole 15.

[0022] The recesses 16 on the inner wall of the positioning hole 15 are evenly distributed circumferentially. In their natural state, the ends of the limiting posts 17 within the recesses 16 are located within the positioning hole 15. Of course, only a small number of these limiting posts 17 are present in the positioning hole 15, used to support the button and keep it stable. The recesses 16 used are stepped holes formed by the joining of rectangular and circular holes; that is, a rectangular hole has a rectangular cross-section, and a circular hole has a circular cross-section. The diameter of the circular hole is larger than the side length of the rectangular hole, so the limiting posts 17 installed within the recesses 16 are composed of a combination of cuboids and cylinders. In its natural state, the compression spring 18 pushes the limiting post 17 into the positioning hole 15, thus keeping the end of the limiting post 17 within the positioning hole 15. The cylindrical size of the limiting post 17 matches the size of the circular hole, so when the cylinder contacts the end of the rectangular hole, the limiting post 17 is restricted from moving into the positioning hole 15. Therefore, by selecting the length of the cuboid of the limiting post 17 according to actual needs, the length of the end of the limiting post 17 entering the positioning post can be effectively controlled. This ensures support for the button while pushing the limiting post 17 into the recessed hole 16 when the button is under pressure, ensuring that the button passes stably through the positioning hole 15.

[0023] The end of the limiting post 17 located within the positioning hole 15 is provided with an upwardly inclined surface. In its natural state, the uppermost end of the inclined surface of the limiting post 17 is located within the recessed hole 16. Because of the inclined surface at the end of the limiting post 17, and the uppermost end of the inclined surface being located within the recessed hole 16, when the button enters the positioning hole 15, the edge of the button contacts the inclined surface on the limiting post 17. When the button is subjected to downward pressure, the limiting post 17 can be pushed into the recessed hole 16, reducing the pushing force required for the button, making the equipment operate more smoothly and reliably, and less likely to damage the button.

[0024] The end of the limiting post 17 located within the positioning hole 15 is provided with a vertically oriented arc-shaped groove, the radius of which is the same as the radius of the positioning hole 15. By providing an arc-shaped groove at the end of the limiting post 17, and ensuring that the radius of this groove matches that of the positioning hole 15, when the button is pressed down and pushed into the recess 16 of the limiting post 17, the end face of the limiting post 17 simultaneously retracts into the inner wall of the positioning hole 15. This allows the entire button to move down stably and naturally, preventing localized interference that could cause instability and flipping of the button, thus greatly improving the reliability of the equipment operation.

[0025] A slide rail 9 is provided on the base plate 1, and a slider 10 is slidably connected to the slide rail 9. The second cylinder 6 is fixed on the slider 10. A horizontal screw 11 is fixed on the slider 10. The screw 11 is aligned with the slide rail 9 and passes through the column 2. A bushing 12 is rotatably connected to the column 2. The bushing 12 is sleeved on the outside of the screw 11 and has an internal thread. The internal thread of the bushing 12 engages with the screw 11 for transmission. Teeth are provided on the outside of the bushing 12. A power motor 13 is provided on the base plate 1 on the side of the bushing 12. A gear 14 is provided on the output shaft of the power motor 13 and meshes with the teeth of the bushing 12.

[0026] Because the second cylinder 6 or positioning mold 7 in the prior art is located below the positioning plate 3, when covering the sweater with the positioning mold 7 after assembling the lower part of the buttons, it is necessary to position the sweater. This results in the view being blocked by the positioning plate 3, making positioning difficult and easily causing the buttons to be inaccurately positioned on the sweater, affecting the quality of the sweater. In this embodiment, a slide rail 9 is provided on the base plate 1 to fix the second cylinder 6 on the slider 10. In this way, when placing the buttons and covering the sweater, the slider 10, the second cylinder 6, and the positioning mold 7 can be moved to the outside of the positioning plate 3. This makes positioning when covering the sweater with the positioning mold 7 much more convenient and greatly improves the operating efficiency. After positioning, the bushing 12 can be rotated by the power motor 13, thereby driving the slider 10 to move on the slide rail 9 through the axial displacement of the lead screw, moving the positioning mold 7 directly below the positioning hole 15. The second cylinder 6 extends to press the sweater between the positioning plate 3 and the positioning mold 7. The operation is convenient. The power motor 13 can be a servo motor with high movement accuracy, ensuring the buttoning accuracy.
