Description

Technical Field

[0001] This utility model relates to the field of sewing technology, and in particular to a button attaching machine. Background Technology

[0002] A button sewing machine is a sewing tool used to sew buttons. Buttons are generally designed with four or two holes. When sewing, the button is held by the clamping mechanism of the button sewing machine. By moving the clamping mechanism, the needle passes through different holes to sew the button.

[0003] The current common design of button sewing machines involves a motor driving two cams, which in turn control the feeding of the clamping mechanism in the X and Y directions via a transmission mechanism, thus enabling the switching of buttonholes. However, buttons come in various types, and the spacing between the holes varies. Operators need to adjust the mechanical positions of the cams or transmission mechanism to adapt the machine to the different button sizes actually used, making the adjustment relatively cumbersome.

[0004] Therefore, how to improve the problem of the cumbersome movement and adjustment of the clamping mechanism in the horizontal plane is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a button-attaching machine that can improve the problem of the cumbersome adjustment of the movement range of the clamping mechanism in the horizontal plane.

The first connecting part is hinged to the strip hole, and the second connecting rod is used to drive the large connecting rod to rotate relative to the base.

[0024] The lifting and pressing link is hinged at one end to the second connecting part and at the other end to the lifting and pressing mechanism. The lifting and pressing link is used to drive the lifting and pressing mechanism to move up or down when the second connecting part rotates.

[0025] In one possible implementation, a base is provided between the connecting rod and the base, and the base has a connecting hole for hinged connection with the connecting rod.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] The purpose of this invention is to provide a button-attaching machine that can improve the problem of the cumbersome adjustment of the movement range of the clamping mechanism in the horizontal plane.

[0040] Please see Figures 1 to 4 To achieve the above objectives, this utility model provides a button-attaching machine, including a base, a limiting member 7, a sliding plate 6, a first power assembly, and a second power assembly. The base includes a lower section 1 and an upper section of the housing. The limiting member 7 is rotatably connected to the base via a first connecting member. The limiting member 7 can rotate relative to the base about the axis of the first connecting member. The first connecting member can be, but is not limited to, a bolt or a pin. The sliding plate 6 has a slot that slides with the limiting member 7. A portion of the outer wall of the limiting member 7 is fitted with the inner wall of the slot for relative sliding along the length of the slot. The front end of the sliding plate 6 is used for connecting... The clamping mechanism includes a first power component consisting of a first power source 3 connected to the base and a first transmission component connected to the output end of the first power source 3 and the slide plate 6. The first power source 3 is specifically connected to the right side of the lower section 1 of the housing and is used to drive the slide plate 6 to swing left and right around the axis of the first connector. The second power component consists of a second power source 15 connected to the base and a second transmission component connected to the output end of the second power source 15 and the slide plate 6. The first power source 3 is specifically connected to the upper section of the housing and the second power source 15 is used to drive the slide plate 6 to slide relative to the limiting member 7 in the length direction of the slot.

[0041] It should be noted that the first power source 3 and the second power source 15 can be, but are not limited to, motors. The motors can rotate to transmit power to the slide plate 6, which can then move the slide plate 6 left and right and back and forth. This allows the clamping mechanism to move the button to the target position, enabling the sewing needle to pass through different holes to sew the button. The first power source 3 can be fixed to the lower section 1 of the housing through the first motor bracket, and the second power source 15 can be fixed to the upper section of the housing through the second motor bracket. Connecting the first power source 3 and the second power source 15 to different positions or areas of the base allows for the rational use of space.

[0042] The limiting member 7 is rotatably connected to the base via the first connecting member. The slide plate 6 has a slot that slides with the limiting member 7, and the front end of the slide plate 6 is used to connect the clamping mechanism. The output end of the first power source 3 is connected to the slide plate 6 via the first transmission assembly, and is used to drive the slide plate 6 to swing left and right around the axis of the first connecting member. The output end of the second power source 15 is connected to the slide plate 6 via the second transmission assembly, and is used to drive the slide plate 6 to slide relative to the limiting member 7 in the length direction of the slot. The first power source 3 and the second power source 15 enable the clamping mechanism to move in the horizontal plane to achieve the switching of buttonholes. Adjusting the rotation angle of the output ends of the first power source 3 and the second power source 15 can adjust the movement of the clamping mechanism in the horizontal plane, which can improve the problem of the cumbersome adjustment of the movement range of the clamping mechanism in the horizontal plane. This effectively improves the accuracy and stability of the button-attaching machine.

[0043] In one possible implementation, the first transmission assembly includes a crank 4 and a connecting rod 5. One end of the crank 4 is fixedly connected to the output end of the first power source 3, and the other end of the crank 4 is hinged to one end of the connecting rod 5. The other end of the connecting rod 5 is hinged to the rear end of the slide plate 6. Specifically, one end of the crank 4 is sleeved on and fixed to the output end of the first power source 3. The output end of the first power source 3 can rotate clockwise or counterclockwise by a certain angle according to the command, thereby driving the crank 4 to rotate and causing the slide plate 6 to rotate to the right or left around the limiting member 7, thus realizing the feeding control in the X direction.

[0044] In one possible implementation, the second transmission assembly includes a cam 14, a bracket 12, a slide rod 9, and a first connecting rod 8. The cam 14 is connected to the output end of the second power source 15. The bracket 12 is movably connected to the cam 14. The slide rod 9 is movably connected to the lower section 1 of the base housing and fixedly connected to the bracket 12. The cam 14 is used to drive the bracket 12 and the slide rod 9 to move synchronously relative to the base in the front-rear direction. One end of the first connecting rod 8 is hinged to the front end of the slide rod 9, and the other end is hinged to the rear of the slide plate 6.

[0045] The cam 14 has a sliding groove, which is an arc-shaped groove extending from the center of the cam 14 to its edge. The bracket 12 has a roller 13 that slides with the sliding groove. Under the control of the electronic control system, after receiving a command, the output end of the second power source 15 can rotate clockwise or counterclockwise by a certain angle. When the output end of the second power source 15 rotates clockwise, the cam 14 also rotates clockwise, the roller 13 moves with the sliding groove, driving the bracket 12 to move, driving the slide rod 9 to move, driving the slide plate 6 to move, and further driving the clamping mechanism to move. When the output end of the second power source 15 rotates counterclockwise, the cam 14 also rotates counterclockwise, the roller 13 moves with the sliding groove, driving the bracket 12 to move, driving the slide rod 9 to move, driving the slide plate 6 to move, and further driving the clamping mechanism. This realizes feeding control in the Y direction, which is an angle between the Y direction and the X direction mentioned above in the horizontal plane.

[0046] Furthermore, to ensure the accurate movement of the slide rod 9, a guide rail bracket 11 is provided between the slide rod 9 and the base. There are two guide rail brackets 11, which are spaced apart in the extension direction of the slide rod 9. A linear bearing 10 is provided inside the guide rail bracket 11 and sleeved on the outer periphery of the slide rod 9. The linear bearing 10 is used for the slide rod 9 to slide relative to the guide rail bracket 11. Specifically, the slide rod 9 can slide freely within the linear bearing 10, effectively reducing the wear and misalignment of the slide rod 9. Alternatively, a bushing can be used to replace the linear bearing 10, as long as the above purpose is achieved, no specific limitation is made here.

[0047] It should be noted that the top of the slide rod 9 has a flat structure, which is located between the two guide rail brackets 11. The bottom of the bracket 12 is fixedly connected to the flat structure. A first mounting hole can be made in the flat structure, and a second mounting hole corresponding to the first mounting hole can be made in the bracket 12. The corresponding first and second mounting holes are connected by a fastener to achieve a fixed connection between the slide rod 9 and the bracket 12. The first and second mounting holes can be, but are not limited to, threaded holes, and the fastener can be, but is not limited to, screws, to facilitate the installation and disassembly of the slide rod 9 and the bracket 12.

[0048] In one possible implementation, the button-attaching machine further includes a third transmission assembly, which includes a second connecting rod 16, a main connecting rod 17, and a lifting and pressing connecting rod 18. One end of the second connecting rod 16 is hinged to the cam 14, and the second connecting rod 16 has a slotted hole. The main connecting rod 17 is rotatably connected to the base, and the main connecting rod 17 has a first connecting part and a second connecting part. The first connecting part is hinged to the slotted hole, and the second connecting rod 16 is used to drive the main connecting rod 17 to rotate relative to the base. One end of the lifting and pressing connecting rod 18 is hinged to the second connecting part, and the other end is used to connect to the lifting and pressing mechanism. The lifting and pressing connecting rod 18 is used to drive the lifting and pressing mechanism to move up or down when the second connecting part rotates. A base 19 is provided between the main connecting rod 17 and the base. The base 19 has a connecting hole for hinged connection with the main connecting rod 17. The axis of the connecting hole is parallel to the rotation axis of the cam 14, so that the cam 14 drives the main connecting rod 17 to rotate around the axis of the connecting hole.

[0049] Under the control of the electronic control system, after receiving an instruction, the output end of the second power source 15 can rotate clockwise or counterclockwise by a certain angle. When the output end of the second power source 15 rotates clockwise, the cam 14 also rotates clockwise, driving the second connecting rod 16 to move, causing the connection between the main connecting rod 17 and the second connecting rod 16 to move to the end of the slot, pushing the main connecting rod 17, driving the lifting and pressing connecting rod 18 to press down the pressure foot of the lifting and pressing mechanism, and at the same time opening the scissor mechanism. When the output end of the second power source 15 rotates counterclockwise, the cam 14 also rotates counterclockwise, driving the second connecting rod 16 to move, causing the connection between the main connecting rod 17 and the second connecting rod 16 to move to the other end of the slot, pushing the main connecting rod 17, driving the lifting and pressing connecting rod 18 to lift away the pressure foot of the lifting and pressing mechanism, and at the same time driving the scissor mechanism to cut the wire. The second power source 15 can both drive the slide plate 6 to move and drive the lifting and pressing mechanism to move.

[0050] In one possible implementation, the limiting member 7 has a limiting portion extending above the slide plate 6 to restrict the slide plate 6 from disengaging from the limiting member 7 in the height direction. The base has multiple mounting positions for mounting the limiting member 7, and the limiting member 7 is detachably connected to any one of the mounting positions to adjust the position of the limiting member 7 as needed.

[0051] In summary, the button-attaching machine provided in this application has a simpler structure and is easier to manufacture compared to existing structures. It eliminates the need for complex mechanical adjustments and allows for digital adjustment via the electronic control system's display screen, thus requiring less skill from the operator. The use of two power sources to move the clamping mechanism in the horizontal plane provides a wider and more precise adjustment range compared to existing structures, effectively improving the machine's accuracy and stability.
