Description

Technical Field

[0001] This utility model belongs to the technical field of button attaching machines, and relates to a button attaching machine. Background Technology

[0002] A button attaching machine is a specialized piece of machinery used to fasten buttons onto clothing or other textiles. Widely used in the garment manufacturing industry, this machine can quickly and efficiently install buttons, significantly improving production efficiency.

[0003] Existing button attaching machines, such as the one disclosed in Chinese patent literature, include a button attaching clamp moving mechanism [Patent No.: 202411263572.9; Application Publication No.: CN118910817A]. This button attaching machine includes a housing, a lower shaft, and a button attaching clamp. A button holder is located above the lower shaft on the housing. The rear end of the button attaching clamp is connected to the rear end of the button holder. The driving mechanism includes a rocker arm, which is rotatably connected to the housing via a rotating shaft. A clearance connector is provided at the front end of the rocker arm. The lower shaft passes through the clearance connector, and the upper end of the clearance connector is movably connected to the front end of the button holder.

[0004] This type of button-attaching machine uses a Y-axis drive motor to move the button clamp along the Y-axis and an X-axis drive motor to move the button clamp along the X-axis. This allows for forward and backward movement and left and right movement of the button clamp on a horizontal plane, aligning the button hole with the sewing needle for button attachment. However, this type of machine also requires a third drive motor to raise and lower the button clamp, increasing manufacturing costs. Furthermore, the third drive motor occupies installation space, making the arrangement of other components inconvenient and increasing the overall size of the machine. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a button-attaching machine. The technical problem solved is how to achieve the forward and backward movement, as well as the lifting and lowering of the clamping structure, through a drive motor.

[0006] The objective of this utility model can be achieved through the following technical solution: A button-attaching machine includes a base and a second drive motor and a clamping structure mounted on the base. The button-attaching machine further includes a second transmission structure connected to the clamping structure and a third transmission structure connected to the clamping structure, both mounted on the base. A cam disk is fixedly connected to the output shaft of the second drive motor. One side of the cam disk has a recessed, annular cam groove. The cam groove includes an outwardly convex, arc-shaped convex section, an inwardly concave, arc-shaped concave section, and a pair of arc-shaped, symmetrically arranged cross sections located between the convex and concave sections. The transition section includes a second transmission structure comprising a second roller embedded in the cam groove, and a third transmission structure comprising a third roller embedded in the cam groove. Initially, the second and third rollers are located in a pair of transition sections. A second drive motor drives the cam disk to rotate in both directions, causing the second roller to enter and leave the concave section, which in turn moves the second transmission structure and the clamping structure back and forth. Conversely, the second drive motor drives the cam disk to rotate in opposite directions, causing the third roller to enter and leave the concave section, which in turn moves the third transmission structure and the clamping structure to lift and lower.

[0007] The convex section is arc-shaped, as are the concave section and the transition section. When the second and third rollers move relative to the cam disc along the convex section, their positions remain unchanged. Their positions only change when they enter and leave the concave section. During operation, the second drive motor rotates forward, causing the second roller to move from the transition section into the concave section via the cam groove wall, changing its position and thus driving the second transmission structure to move, causing the clamping structure to move backward. Subsequently, the second drive motor rotates in reverse, causing the second roller to leave the concave section and return to the transition section via the cam groove wall, again changing its position and driving the second transmission structure to move in the opposite direction, causing the clamping structure to move forward, thus achieving the forward and backward movement of the clamping structure. During this process, the third roller moves along the convex section without changing its position; that is, the third transmission structure remains stationary. The second drive motor reverses direction, causing the third roller to move from the transition section into the concave section via the cam groove wall. This changes the position of the third roller, thereby moving the third transmission structure and lifting the clamping structure. Subsequently, the second drive motor rotates forward, causing the third roller to leave the concave section and return to the transition section via the cam groove wall, again changing its position and moving the third transmission structure to lower the clamping structure. During this process, the second roller moves along the convex section without changing its position; that is, the second transmission structure remains stationary. This button-attaching machine, through the cooperation of the cam groove, the second roller, and the third roller, allows the second drive motor to drive the second and third transmission structures independently, eliminating interference between their movements. This button-attaching machine uses a single drive motor to achieve the forward and backward movement, lifting, and lowering of the clamping structure, reducing the need for a separate drive motor, lowering costs, saving installation space, and allowing for a more rational arrangement of other components.

[0008] In the aforementioned button-attaching machine, the center of the convex section overlaps with the central axis of the output shaft of the second drive motor, and the line connecting the highest point of the convex section and the lowest point of the concave section passes through the central axis of the output shaft of the second drive motor. This structure makes the structure of the cam disc and cam groove more symmetrical and reasonable, improving the movement accuracy of the cam disc driving the second and third rollers.

[0009] In the aforementioned button-attaching machine, the machine further includes a first drive motor and a first transmission structure mounted on the machine base. The first drive motor is connected to the clamping structure via the first transmission structure, and the first drive motor can drive the clamping structure to move left and right through the first transmission structure. When the first drive motor rotates forward, it drives the clamping structure to move to the right via the first transmission structure; when the first drive motor rotates in reverse, it drives the clamping structure to move to the left via the first transmission structure, thus realizing the left-right movement of the clamping structure.

[0010] In the aforementioned button-attaching machine, the bottom of the machine base has a mounting cavity, in which both the first drive motor and the second drive motor are located. The first transmission structure and the second transmission structure are both located at the tail end of the machine base, and both are directly above the mounting cavity. This structure makes efficient use of space, resulting in a compact button-attaching machine.

[0011] In the aforementioned button-attaching machine, the clamping structure includes a pressing member, a clamping seat, and a button clip. The front end of the clamping seat is movably pressed against the machine base by the pressing member. The tail end of the button clip is hinged to the middle of the clamping seat. The first transmission structure and the second transmission structure are both connected to the clamping seat, and the third transmission structure is connected to the front end of the button clip. The pressing member presses the clamping seat against the machine base but does not lock it. When sufficient external force pushes the clamping seat, the clamping seat can move relative to the machine base.

[0012] In the aforementioned button-attaching machine, the first transmission structure includes a first connecting rod, a second connecting rod, and a third connecting rod. The output shaft of the first drive motor is fixedly connected to the first connecting rod, and the third connecting rod is fixedly connected to the tail end of the clamping seat. One end of the second connecting rod is hinged to the first connecting rod, and the other end is hinged to the tail end of the third connecting rod. The second connecting rod is located above the first and third connecting rods. The first drive motor drives the first connecting rod to rotate, and the second connecting rod can deflect the third connecting rod, thereby allowing the clamping seat to move left and right around the pressing member. The arrangement of the third connecting rod makes the second connecting rod more reasonable and does not require changing the structure of the clamping seat.

[0013] In another scenario, in one of the button-attaching machines described above, the first transmission structure includes a first connecting rod and a second connecting rod. The output shaft of the first drive motor is fixedly connected to the first connecting rod, and one end of the second connecting rod is hinged to the first connecting rod, while the other end is hinged to the tail end of the clip seat. This structure requires an integrally formed protrusion at the tail end of the clip seat, allowing the first drive motor to be directly connected to the clip seat via the first and second connecting rods.

[0014] In the aforementioned button-attaching machine, the second transmission structure includes a fourth link, a fifth link, a sixth link, and a seventh link. One end of the fourth link is hinged to the second roller, and the other end is hinged to the machine base. One end of the fifth link is hinged to the middle of the fourth link, and the other end is hinged to one end of both the sixth and seventh links. The other end of the sixth link is hinged to the clamping seat, and the other end of the seventh link is hinged to the machine base. The hinge points of the fifth, sixth, and seventh links form a triangle, which can absorb the deformation caused by the change in position of the second roller in the cam disc, preventing the second transmission structure from jamming and allowing it to drive the clamping structure to move back and forth. The fourth link provides greater force when the cam disc rotates, reducing the power consumption of the second drive motor.

[0015] In another embodiment of the button-attaching machine described above, the second transmission structure includes a fifth link, a sixth link, and a seventh link. One end of the fifth link is hinged to the second roller, and the other end is hinged to one end of both the sixth and seventh links. The other end of the sixth link is hinged to the button clamp, and the other end of the seventh link is hinged to the machine base. This structure simplifies the design of the second transmission structure.

[0016] In the aforementioned button-attaching machine, the button-attaching machine includes a cutting structure located in the machine base. The third transmission structure includes an eighth link, a universal link with fisheye joints at both ends, a Z-shaped ninth link, a tenth link, an eleventh link, and a lifting hook. One end of the eighth link is hinged to the third roller, and the other end is hinged to the machine base. One end of the universal link is hinged to the middle of the eighth link, and the other end is hinged to the middle of the ninth link. The turning point above the ninth link is hinged to the machine base, and the turning point below the ninth link is connected to the cutting structure. The top end of the ninth link is hinged to the bottom end of the tenth link, and the top end of the tenth link is hinged to the tail end of the eleventh link. The middle part of the eleventh link is hinged to the machine base, and the front end of the eleventh link is connected to the front end of the button clamp via the lifting hook. This structure allows the third transmission structure to drive the clamping structure to lift and lower, while simultaneously driving the cutting structure to cut lines. The cutting structure is existing technology, and its specific structure will not be described in detail.

[0017] In another embodiment, in the aforementioned button-attaching machine, the third transmission structure includes an eighth link, a universal link with fisheye joints at both ends, an L-shaped ninth link, a tenth link, an eleventh link, and a lifting hook. One end of the eighth link is hinged to the third roller, and the other end is hinged to the machine base. One end of the universal link is hinged to the middle of the eighth link, and the other end is hinged to one end of the ninth link. The middle of the ninth link is hinged to the machine base, and the other end of the ninth link is hinged to the bottom end of the tenth link. The top end of the tenth link is hinged to the tail end of the eleventh link, and the middle of the eleventh link is hinged to the machine base. The front end of the eleventh link is connected to the front end of the button clamp via the lifting hook. The spherical joints at both ends of the universal joint can absorb the deformation caused by the change in position of the third roller in the cam plate, so that the third transmission structure will not jam, thus allowing the third transmission structure to drive the clamping structure to lift and lower; the eighth link allows the cam plate to have greater force when rotating, which can reduce the power of the second drive motor.

[0018] Compared with the prior art, the button-attaching machine provided by this utility model has the following advantages:

[0019] 1. This button attaching machine can realize the forward and backward movement, left and right movement, and lifting and lowering of the clamping structure through two drive motors. This can reduce one drive motor, reduce costs, save installation space, and make the arrangement of other parts of the button attaching machine more convenient.

[0020] 2. This button-attaching machine uses a cam groove in the cam plate to ensure that the position of the second roller changes while the position of the third roller does not, and vice versa. This eliminates interference between the second and third transmission structures, allowing the second drive motor to move the clamping structure forward and backward, as well as lift and lower it.

[0029] 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.

[0030] Example 1

[0031] like Figure 1 As shown, this button-attaching machine includes a base 1, a first drive motor 2, a second drive motor 3, a first transmission structure 4, a clamping structure 5, a second transmission structure 6, a third transmission structure 7, and a cam disc 8.

[0032] The bottom of the tail end of the base 1 has a mounting cavity 10. The first drive motor 2 and the second drive motor 3 are both located in the mounting cavity 10. The first transmission structure 4 and the second transmission structure 6 are both located at the tail end of the base 1, and both the first transmission structure 4 and the second transmission structure 6 are located directly above the mounting cavity 10. The third transmission structure 7 is partially located at the tail end of the base 1, and the rest is located at the top of the base 1. The clamping structure 5 includes a clamping member 51, a clamping seat 52, and a snap fastener 53. The front end of the clamping seat 52 is movably clamped onto the base 1 by the clamping member 51, and the tail end of the snap fastener 53 is hinged to the middle of the clamping seat 52.

[0033] The first drive motor 2 can drive the clamping structure 5 to move left and right through the first transmission structure 4. Specifically, for example...

The output shaft of the first drive motor 2 is fixedly connected to the first connecting rod 41. The third connecting rod 43 is fixedly connected to the tail end of the clamp seat 52. One end of the second connecting rod 42 is hinged to the first connecting rod 41 and the other end is hinged to the tail end of the third connecting rod 43. The second connecting rod 42 is located above the first connecting rod 41 and the third connecting rod 43.

[0034] A cam disk 8 is fixedly connected to the output shaft of the second drive motor 3, such as Figure 5 As shown, one side of the cam disk 8 has a recessed and annular cam groove 9. The cam groove 9 includes an outwardly convex and arc-shaped convex section 91, an inwardly concave and arc-shaped concave section 92, and a pair of arc-shaped and symmetrically arranged transition sections 93 located between the outwardly convex section 91 and the concave section 92. The center of the outwardly convex section 91 overlaps with the central axis of the output shaft of the second drive motor 3. The line connecting the highest point of the outwardly convex section 91 and the lowest point of the concave section 92 passes through the central axis of the output shaft of the second drive motor 3.

[0035] The second drive motor 3 can drive the clamping structure 5 to move back and forth through the cam disk 8 and the second transmission structure 6. Specifically, as follows: Figure 3 As shown, the second transmission structure 6 includes a second roller 61, a fourth connecting rod 62, a fifth connecting rod 63, a sixth connecting rod 64, and a seventh connecting rod 65. One end of the fourth connecting rod 62 is hinged to the second roller 61, and the other end is hinged to the machine base 1. One end of the fifth connecting rod 63 is hinged to the middle of the fourth connecting rod, and the other end is hinged to one end of both the sixth connecting rod 64 and the seventh connecting rod 65. The other end of the sixth connecting rod 64 is hinged to the clamp seat 52, and the other end of the seventh connecting rod 65 is hinged to the machine base 1.

[0036] The second drive motor 3 can drive the clamping structure 5 to lift and lower via the cam disc 8 and the third transmission structure 7. Specifically, as follows: Figure 4As shown, the button-attaching machine includes a cutter structure located in the base 1. The cutter structure is not shown in the diagram and is existing technology, so it will not be described in detail. The third transmission structure 7 includes an eighth link 72, a universal link 73 with fisheye joints 731 at both ends, a Z-shaped ninth link 74, tenth link 75, eleventh link 76, and a lifting hook 77. One end of the eighth link 72 is hinged to the third roller 71, and the other end is hinged to the base 1. One end of the universal link 73 is connected to the eighth link 74... The middle part of 2 is hinged, and the other end is hinged to the middle part of the ninth link 74. The turning point above the ninth link 74 is hinged to the machine base 1. The turning point below the ninth link 74 is connected to the cutting structure. The top end of the ninth link 74 is hinged to the bottom end of the tenth link 75. The top end of the tenth link 75 is hinged to the tail end of the eleventh link 76. The middle part of the eleventh link 76 is hinged to the machine base 1. The front end of the eleventh link 76 is connected to the front end of the nail clip 53 through the lifting hook 77.

[0037] During operation, the first drive motor 2 rotates forward, driving the clamping structure 5 to move to the right via the first transmission structure 4. Conversely, the first drive motor 2 rotates in reverse, driving the clamping structure 5 to move to the left via the first transmission structure 4, thus achieving the left-right movement of the clamping structure 5. Figure 5 As shown, the second roller 61 and the third roller 71 are initially located in a pair of transition sections 93, as... Figure 6 As shown, the second drive motor 3 rotates forward, causing the second roller 61 to move from the transition section 93 to the concave section 92. At this time, the third roller 71 moves from the transition section 93 to the convex section 91. The position of the second roller 61 in the cam disk 8 changes, while the position of the third roller 71 remains unchanged. The second roller 61 moves the second transmission structure 6, thereby driving the clamping structure 5 to move backward. Subsequently, the second drive motor 3 reverses, causing the second roller 61 to move from the concave section 92 to the transition section 93. At this time, the third roller 71 moves from the convex section 91 to the transition section 93. The position of the second roller 61 in the cam disk 8 changes again, while the position of the third roller 71 remains unchanged. The second roller 61 moves the second transmission structure 6, thereby driving the clamping structure 5 to move forward, thus realizing the forward and backward movement of the clamping structure 5. Figure 7As shown, the second drive motor 3 reverses, causing the third roller 71 to move from the transition section 93 to the concave section 92. At this time, the second roller 61 moves from the transition section 93 to the convex section 91. The position of the third roller 71 in the cam disk 8 changes, while the position of the second roller 61 remains unchanged. The third transmission structure 7 moves through the third roller 71, thus lifting the clamping structure 5. Subsequently, the second drive motor 3 rotates forward, causing the third roller 71 to move from the concave section 92 to the transition section 93. At this time, the second roller 61 moves from the convex section 91 to the transition section 93. The position of the third roller 71 in the cam disk 8 changes again, while the position of the second roller 61 remains unchanged. The third transmission structure 7 moves through the third roller 71, thus lowering the clamping structure 5. This achieves the lifting and lowering of the clamping structure 5.
