Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, specifically to a button-fastening device for sweaters. Background Technology

[0002] Sweaters not only provide warmth and comfort, but also offer a variety of styles through different combinations, making them suitable for various occasions. Sweater fashion trends and popular elements are constantly evolving. During sweater production, buttons are attached. To improve installation efficiency, button-attaching devices are used. Existing devices typically use a pressure head to squeeze the button, forcing its lower end to pierce the sweater. Then, the lower end of the button expands and tightens a gasket to secure it. This method offers good installation convenience. However, to facilitate the opening of the lower end of the button, it is generally tubular. This lack of guidance during the insertion of the button through the sweater can easily cut the sweater's yarn, resulting in loose threads that affect the sweater's production quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a button-attaching device for sweaters. During the installation of the button, a conical head pierces the sweater and opens the installation hole. Then, the extended guide strip can guide the lower end of the button through the sweater, which can avoid the breakage of the yarn caused by directly piercing the sweater with the button, thereby ensuring the production quality of the sweater and effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a button-attaching device for sweaters, comprising a frame, a worktable in the middle of the frame, a pressure seat slidably connected to the upper end of the frame, and a conical pressure head slidably connected to the lower end of the frame, the conical pressure head corresponding vertically to the pressure seat, a uniformly distributed and retractable guide strip slidably connected to the lower end of the conical pressure head, a movable column slidably connected to the lower end of the conical pressure head, the lower ends of multiple guide strips being rotatably connected to the lower ends of the movable column, and a long sliding hole being opened in the middle of each guide strip. A uniformly distributed sliding column is provided in the upper end of the conical pressure head, and each sliding column is slidably connected to a vertically corresponding long sliding hole. During the button-attaching process, the conical head pierces the sweater, opening the installation hole, and then the extended guide strip guides the lower end of the button through the sweater for expansion and fixation. This avoids directly piercing the sweater with the button, which could cause the yarn to break, thus ensuring the production quality of the sweater.

[0005] Furthermore, the long sliding hole is inclined from bottom to top away from the axis of the conical pressure head, and its upper end will open as the four guide bars extend.

[0006] Furthermore, the front end of the workbench is equipped with a controller, the input of which is electrically connected to an external power source for convenient automatic control of electrical appliances.

[0007] Furthermore, a guide plate is slidably connected to the middle of the conical pressure head, the guide plate passes through the moving column, and a second long sliding hole is opened in the middle of the guide plate. A second sliding column is provided in the middle of the moving column, and the second sliding column is slidably connected to the second long sliding hole. The second long sliding hole is opened at an upward angle from left to right. A push-pull electromagnet is provided in the middle of the conical pressure head through a support base. The telescopic end of the push-pull electromagnet is fixedly connected to the right end of the guide plate. The input end of the push-pull electromagnet is electrically connected to the output end of the controller to facilitate the control of the movement of the moving column.

[0008] Furthermore, a flared hole is provided in the middle of the lower surface of the pressure seat, and a positioning groove is provided in the middle of the upper surface of the worktable to facilitate the positioning of the fastener.

[0010] Furthermore, the lower end of the frame is provided with an electric cylinder, the telescopic end of which is fixedly connected to the lower end of the conical pressure head. A support plate is slidably connected to the middle of the frame, and the front end of the support plate is fixedly connected to the conical pressure head. The input end of the electric cylinder is electrically connected to the output end of the controller to facilitate the control of the movement of the conical pressure head.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This sweater button sewing device has the following advantages:

[0012] During the installation of the fastener, a conical head pierces the sweater to open the installation hole.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This embodiment provides a technical solution: a button-attaching device for sweaters, including a frame 1, which provides support for other components. A worktable 2 is located in the middle of the frame 1, on which the sweater is placed. A pressure seat 3 is slidably connected to the upper end of the frame 1, and a conical pressure head 4 is slidably connected to the lower end of the frame 1. The conical pressure head 4 corresponds vertically to the pressure seat 3. The pressure seat 3 positions the button, and the conical pressure head 4 presses the lower end of the button, causing it to deform and expand. The lower end of the button will then be larger than the through hole of the pad, thus completing the button installation. Four evenly distributed and retractable guide strips 5 are slidably connected inside the lower end of the conical pressure head 4. A movable column 6 is slidably connected inside the lower end of the conical pressure head 4. The lower ends of each guide bar 5 are rotatably connected to the lower ends of the moving column 6. Each guide bar 5 has a long sliding hole 8 in its middle. The upper end of the conical pressure head 4 has evenly distributed sliding columns 7, each sliding column 7 slidably connected to the vertically corresponding long sliding hole 8. The long sliding hole 8 is inclined from bottom to top away from the axis of the conical pressure head 4. A controller 19 is located at the front end of the worktable 2. The input end of the controller 19 is electrically connected to an external power source. A guide plate 9 is slidably connected to the middle of the conical pressure head 4, passing through the moving column 6. A second long sliding hole 11 is opened in the middle of the guide plate 9. A second sliding column 10 is located in the middle of the moving column 6, slidably connected to the second long sliding hole 11. The second long sliding hole 11 is inclined upwards from left to right. The middle of the conical pressure head 4... A push-pull electromagnet 12 is installed on the support base. The telescopic end of the push-pull electromagnet 12 is fixedly connected to the right end of the guide plate 9. The input end of the push-pull electromagnet 12 is electrically connected to the output end of the controller 19. The telescopic end of the push-pull electromagnet 12 drives the guide plate 9 to move to the left. The second long sliding hole 11 slides relative to the second sliding column 10, and drives the moving column 6 to move upward. The moving column 6 pushes the guide strip 5 upward. The upper end of the guide strip 5 extends out from the inside of the conical pressure head 4. The first long sliding hole 8 on the guide strip 5 slides relative to the first sliding column 7. The first long sliding hole 8 is set at an angle. As the four guide strips 5 move upward, their upper ends will open. The upper ends of the guide strips 5 will pass through the sweater and place the button on the upper end of the conical pressure head 4. The four guide strips 5 press the button. The support is in place, and then the pressure seat 3 and the conical pressure head 4 move downwards, causing the fastener to move downwards synchronously with the conical pressure head 4. The lower end of the fastener will pass through the sweater and the pad. A flared hole 18 is provided in the middle of the lower surface of the pressure seat 3. The flared hole 18 facilitates the positioning of the fastener and provides clearance for the guide strip 5. A positioning groove 15 is provided in the middle of the upper surface of the workbench 2. The pad of the fastener is placed inside the positioning groove 15. An electric cylinder 16 is provided at the upper end of the frame 1. The telescopic end of the electric cylinder 16 is fixedly connected to the upper surface of the pressure seat 3. The electric cylinder 16 drives the pressure seat 3 to move downwards to press the sweater tightly. Two guide shafts 17 are slidably connected to the upper end of the frame 1. The lower ends of the guide shafts 17 are fixedly connected to the upper surface of the pressure seat 3. The guide shafts 17 provide guidance for the pressure seat 3.The input terminal of electric cylinder 16 is electrically connected to the output terminal of controller 19. Electric cylinder 13 is located at the lower end of the frame 1. The telescopic end of electric cylinder 13 is fixedly connected to the lower end of the conical pressure head 4. The extension of the telescopic end of electric cylinder 13 causes the conical pressure head 4 to move upwards and pierce the sweater. A support plate 14 is slidably connected to the middle of the frame 1. The front end of the support plate 14 is fixedly connected to the conical pressure head 4, providing support for the movement of the conical pressure head 4. The input terminal of electric cylinder 13 is electrically connected to the output terminal of controller 19.

[0019] The working principle of the button-attaching device for sweaters provided by this utility model is as follows: In use, the button pad is placed inside the positioning groove 15, and then the sweater is placed on the upper surface of the workbench 2. The controller 19 is then activated, and the electric cylinder 16 drives the pressure seat 3 downwards to press the sweater firmly. Then, the telescopic end of the electric cylinder 13 extends, driving the conical pressure head 4 upwards to pierce the sweater. Then, the telescopic end of the push-pull electromagnet 12 drives the guide plate 9 to move to the left, causing the long sliding hole 11 to slide relative to the sliding column 10, and driving the moving column 6 upwards. The moving column 6 pushes the guide strip 5 upwards, and the upper end of the guide strip 5 extends from inside the conical pressure head 4. The long sliding hole 8 on the guide strip 5 slides relative to the sliding column 7. The long sliding hole 8 is tilted, allowing the needle to pass through. As the four guide bars 5 move upward, their upper ends open, and the upper ends of the guide bars 5 pass through the sweater. Then, the pressure seat 3 moves upward and separates from the sweater. The fastener is then placed on the upper end of the conical pressure head 4, and the four guide bars 5 support the fastener. Then, the pressure seat 3 and the conical pressure head 4 move downward, causing the fastener to move downward synchronously with the conical pressure head 4. The lower end of the fastener will pass through the sweater and the pad. Then, the push-pull electromagnet 12 is de-energized, and its telescopic end moves the guide plate 9 to the right under the action of its own spring. Then, the guide bars 5 retract into the inside of the conical pressure head 4. Then, the pressure seat 3 positions the fastener, and the conical pressure head 4 squeezes the lower end of the fastener, causing the lower end of the fastener to deform and expand. The lower end of the fastener will be larger than the through hole of the pad, thus completing the installation of the fastener.

[0020] It is worth noting that the push-pull electromagnet 12, electric cylinder one 13, electric cylinder two 16 and controller 19 disclosed in the above embodiments can be freely configured according to the actual application scenario. The push-pull electromagnet 12 can be a push-pull electromagnet of model ZYE1-1564Z. Both electric cylinder one 13 and electric cylinder two 16 can be direct-drive servo electric cylinders of model SFA80. The core chip of the controller 19 can be a single-chip microcomputer of model STM32H743. The controller 19 controls the operation of the push-pull electromagnet 12, electric cylinder one 13 and electric cylinder two 16 using methods commonly used in the prior art.
