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 drive structure for a button-attaching machine clamping device [Patent No.: 202322246525.0; Application Publication No.: CN220767345U]. This structure includes a frame, on which a clamping device is slidably mounted in all directions. A drive motor 1 for controlling the forward and backward movement of the clamping device is located at the rear end of the frame. A drive motor 2 for controlling the left and right movement of the clamping device is located on one side of the rear end of the frame. A swing rod is mounted on the motor shaft of the drive motor 2. One end of the swing rod is movably connected to a connecting rod, which is movably connected to the clamping device. The drive motor 2 drives the swing rod to swing, and the swing rod drives the clamping device to move left and right through the connecting rod.

[0004] In this type of button-attaching machine, both drive motor one and drive motor two are fixed outside the frame, occupying a large amount of external space and making the machine's structure loose. Furthermore, the rotating disc and drive plate are also located outside the frame, increasing the risk of them colliding with other objects during rotation and causing malfunctions. Moreover, drive motors one and two can only enable the clamping device to slide forward, backward, left, and right; however, the clamping device also needs to be lifted and lowered during operation, requiring an additional drive motor, further increasing the space occupied by this type of button-attaching machine. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a button sewing machine. The technical problem solved is how to prevent the first and second drive motors from being exposed and how to enable the clamping structure to be lifted and lowered.

[0006] The objective of this utility model can be achieved through the following technical solution: A button attaching machine includes a base, a first drive motor, a first transmission structure, a second drive motor, a second transmission structure, and a clamping structure disposed on the base. The first drive motor can drive the clamping structure to move left and right through the first transmission structure, and the second drive motor can drive the clamping structure to move back and forth through the second transmission structure. The button attaching machine further includes a third drive motor and a third transmission structure. The first drive motor and the second drive motor are both located in the mounting cavity at the bottom of the tail end of the base. The first transmission structure and the second transmission structure are both located inside the tail end of the base and above the first drive motor and the second drive motor. The third drive motor is fixedly connected to the top of the tail end of the base, and the third transmission structure is located inside the top of the base. The third drive motor can drive the clamping structure to lift and lower through the third transmission structure.

[0007] The first and second drive motors of this button-attaching machine are both located in the mounting cavity at the bottom of the tail end of the machine base. The first and second transmission structures are also located within the tail end of the machine base, meaning that the first drive motor, first transmission structure, second drive motor, and second transmission structure are not exposed and will not come into contact with external objects, reducing the failure rate. The first and second transmission structures are located above the first and second drive motors, making full use of the vertical space of the machine base and reducing the horizontal width of the tail end, thus minimizing the horizontal space occupied by the tail end. This button-attaching machine uses a third drive motor and a third transmission structure to raise and lower the clamping structure, enabling it to move forward and backward, left and right, and to raise and lower. Simultaneously, the third drive motor is fixed to the top of the tail end of the machine base. Since there are fewer components in the top of the tail end of the machine base, the third drive motor can be partially retracted into the top of the tail end of the machine base, making full use of the vertical space of the machine base and reducing the horizontal space occupied by the button-attaching machine.

[0008] 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, and 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.

[0009] In the aforementioned button sewing 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 clip seat. One end of the second connecting rod is hinged to one end of 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 connecting rod and the third connecting rod. 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 clip seat to move left and right around the clamping member. The arrangement of the third connecting rod makes the second connecting rod more reasonable and does not require changing the structure of the clip seat.

[0010] In the aforementioned button sewing machine, the second transmission structure includes a cam disk and a first roller. The output shaft of the second drive motor is fixedly connected to the cam disk. One side of the cam disk has a recessed cam groove, which includes an outwardly convex, arc-shaped convex section, an inwardly concave, arc-shaped concave section, and a pair of arc-shaped, symmetrically arranged transition sections located between the convex and concave sections. Initially, the first roller is located in one of the transition sections. The second drive motor drives the cam disk to rotate, causing the first roller to enter or leave the concave section, thus moving the second transmission structure and driving the snap-fit ​​structure to move back and forth. The convex section is arc-shaped, and both the concave and transition sections are arc-shaped. When the cam disk rotates, as the first roller crosses the transition section and enters or leaves the concave section, its position in the cam disk changes, thereby moving the second transmission structure and realizing the snap-fit ​​structure's back-and-forth movement. When the first roller moves along the convex section, its position in the cam disk does not change, and the second transmission structure does not move.

[0011] In the aforementioned button sewing 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 improves the accuracy of the cam disc drive.

[0012] In the aforementioned button sewing machine, the second transmission structure further includes a fourth link, a fifth link, a sixth link, and a seventh link. One end of the fourth link is hinged to the first 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 clip 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 first roller in the cam disc, preventing the second transmission structure from jamming and allowing it to drive the clip 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.

[0013] In the aforementioned button-attaching machine, the machine further includes a cutting structure located in the machine base, an eighth connecting rod located in the tail end of the machine base, a universal connecting rod with fisheye joints at both ends, and a ninth connecting rod. A second roller is provided in the cam groove. The first and second rollers are initially symmetrically arranged in a pair of transition sections. One end of the eighth connecting rod is hinged to the second roller, and the other end is hinged to the machine base. One end of the universal connecting rod is hinged to the middle of the eighth connecting rod, and the other end is hinged to the middle of the ninth connecting rod. The top of the ninth connecting rod is hinged to the machine base, and the bottom of the ninth connecting rod is connected to the cutting structure. The fisheye joints at both ends of the universal connecting rod can absorb the deformation caused by the change in position of the second roller in the cam disc, preventing the cutting structure from jamming. The eighth connecting rod allows the cam disc to have greater force when rotating, reducing the power of the second drive motor.

[0014] In the aforementioned button sewing machine, the third transmission structure includes a tenth link, an eleventh link, a twelfth link, and a lifting hook. The output shaft of the third drive motor is fixedly connected to the tenth link. One end of the eleventh link is hinged to one end of the tenth link, and the other end is hinged to the tail end of the twelfth link. The middle part of the twelfth link is hinged to the machine base, and the front end of the twelfth link is connected to the front end of the button clamp via the lifting hook. The inclusion of the eleventh link allows the cam disc to generate greater force during rotation, thus reducing the power consumption of the third drive motor.

[0015] Compared with the prior art, the button sewing machine provided by this utility model has the following advantages:

[0016] 1. This button attaching machine uses a first drive motor and a second drive motor to realize the forward and backward movement and left and right movement of the clamping structure, as well as the cutting action of the cutting blade structure. This is equivalent to reducing one drive motor for the cutting blade structure, thus reducing the cost of the button attaching machine.

[0017] 2. The first drive motor, the first transmission structure, the second drive motor, and the second transmission structure of this button attaching machine are all located inside the machine base and are not exposed. The first transmission structure and the second transmission structure are both located above the first drive motor and the second drive motor. By making full use of the vertical space of the machine base, the horizontal width of the tail of the machine base can be reduced, and the horizontal space occupied by the tail of the machine base can be reduced.

Figure 3 As shown, the second transmission structure 5 includes a cam disk 51, a first roller 52, a fourth connecting rod 54, a fifth connecting rod 55, a sixth connecting rod 56, and a seventh connecting rod 57. The output shaft of the second drive motor 4 is fixedly connected to the cam disk 51. One side of the cam disk 51 has a recessed cam groove 53. The cam groove 53 includes an outwardly convex and arc-shaped convex section 531, an inwardly concave and arc-shaped concave section 532, and a pair of arc-shaped and symmetrically arranged transition sections 533 located between the outwardly convex section 531 and the concave section 532. The center of the outwardly convex section 531 overlaps with the central axis of the output shaft of the second drive motor 4. The line connecting the highest point of the outwardly convex section 531 and the lowest point of the concave section 532 passes through the central axis of the output shaft of the second drive motor 4. One end of the fourth link 54 is hinged to the first roller 52, and the other end is hinged to the machine base 1. One end of the fifth link 55 is hinged to the middle of the four links, and the other end is hinged to one end of the sixth link 56 and the seventh link 57. The other end of the sixth link 56 is hinged to the clamp seat 62, and the other end of the seventh link 57 is hinged to the machine base 1.

At this time, the second roller 14 moves from the transition section 533 to the convex section 531. The position of the first roller 52 in the cam disk 51 changes, while the position of the second roller 14 remains unchanged. The first roller 52 causes the second transmission structure 5 to move, thereby driving the clamping structure 6 to move backward. Subsequently, the second drive motor 4 rotates in reverse, causing the first roller 52 to move from the concave section 532 to the transition section 533. At this time, the second roller 14 moves from the convex section 531 to the transition section 533. The position of the first roller 52 in the cam disk 51 changes again, while the position of the second roller 14 remains unchanged. The first roller 52 causes the second transmission structure 5 to move, thereby driving the clamping structure 6 to move forward, thus realizing the forward and backward movement of the clamping structure 6. Figure 7 As shown, the second drive motor 4 reverses, causing the second roller 14 to move from the transition section 533 to the concave section 532. At this time, the first roller 52 moves from the transition section 533 to the convex section 531. The position of the second roller 14 in the cam disk 51 changes, while the position of the first roller 52 remains unchanged. The second roller 14 drives the cutting structure 10 to cut the wire. Subsequently, the second drive motor 4 rotates forward, causing the second roller 14 to move from the concave section 532 to the transition section 533. At this time, the first roller 52 moves from the convex section 531 to the transition section 533. The position of the second roller 14 in the cam disk 51 changes again, while the position of the first roller 52 remains unchanged. The second roller 14 drives the cutting structure 10 to reset. The third drive motor 7 rotates forward, lifting the clamping structure 6. The third drive motor 7 rotates in reverse, lowering the clamping structure 6.
