Description

Technical Field

[0001] This utility model relates to the field of button attaching machine technology, and specifically to a three-step drive structure for a button attaching machine and the button attaching machine itself. Background Technology

[0002] A button sewing machine is a sewing tool used to sew buttons. Buttons are generally set with four or two holes. The spacing between the holes is different for different buttons. When sewing, the button is held by the button clamp of the button sewing machine. By moving the button clamp, the needle passes through different holes to sew the button.

[0003] For example, Chinese Utility Model Patent No. CN202321669856.9 discloses a button-attaching machine, which includes a feeding motor assembly, a drive rod assembly, a feeding plate, a slider, and a button clip. The feeding plate is provided with a sliding groove, and the slider is located in the sliding groove. One end of the drive rod assembly is hinged to the feeding motor assembly, and the other end is hinged to one end of the feeding plate. The other end of the feeding plate is connected to the button clip. The feeding plate rotates around the slider or moves relative to the slider under the driving action of the feeding motor assembly and the drive rod assembly.

[0004] When the first motor and the second motor rotate simultaneously in one direction, the feed plate can be rotated under the action of the first crankshaft, the first connecting rod, the second crankshaft, and the second connecting rod; when the first motor and the second motor rotate in opposite directions, the feed plate can be moved.

[0005] Therefore, whether controlling the feed plate to move forward and backward or rotate left and right, two motors need to run simultaneously to achieve the above actions. The structure is complex and the control is cumbersome, so further improvements to the structure are needed. Utility Model Content

[0006] The purpose of this invention is to provide a three-step drive structure for a button-attaching machine, which uses two motors to control the forward and backward and left and right movements of the feeding plate, thereby solving the problems of complex structure and cumbersome control in existing systems.

[0007] The purpose of this utility model is achieved as follows: a three-step drive structure for a button-attaching machine, including a feeding slide plate, a clamping assembly installed at one end of the feeding slide plate, and a stepper motor one and a stepper motor two respectively installed at the other end of the feeding slide plate;

[0008] An output wheel is mounted on the output shaft of a stepper motor, and a slider is provided at the eccentric part of the output wheel. A connecting part is formed at the other end of the feeding slide plate, and a groove is provided in the connecting part for the slider to slide, so as to realize the feeding action of the feeding slide plate in the Y-axis direction.

[0009] The output shaft of the second stepper motor is equipped with an output wheel, and a feeding link is hinged to the eccentric part of the output wheel. The other end of the feeding link is hinged to the mounting seat in the middle of the feeding slide to realize the feeding action of the feeding slide in the X-axis direction.

[0010] Preferably, one end of the feeding slide plate is provided with a strip-shaped guide hole, a second slider is provided in the strip-shaped guide hole, a limit piece is provided on the upper end surface of the second slider, and a fixing component is installed in the second slider to fix it to the machine body.

[0011] Preferably, it also includes a wire cutting assembly, a pressure foot lifting assembly, and a stepper motor for driving the wire cutting assembly and the pressure foot lifting assembly to perform actions.

[0012] Preferably, a drive wheel is mounted on the output shaft of the stepper motor three, and the drive wheel is respectively formed with a wire-cutting cam and a pressure foot lifting cam.

[0013] Preferably, a wire-cutting drive rod is provided on one side of the wire-cutting cam, a wire-cutting connecting rod is connected to the other end of the wire-cutting drive rod, a wire-cutting push rod is connected to the other end of the wire-cutting connecting rod, and a wire-cutting assembly is provided at the other end of the wire-cutting push rod.

[0014] Preferably, a lifting drive rod is provided on one side of the lifting foot cam portion, the other end of the lifting drive rod is connected to a lifting connecting rod, the other end of the lifting connecting rod is connected to a lifting lever, and the other end of the lifting lever is provided with a lifting foot assembly.

[0015] A button-attaching machine includes a three-step drive structure as described in any of the preceding claims.

[0016] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, a three-step drive structure for a button-attaching machine includes a feeding slide plate 1, a clamping assembly 2 installed at one end of the feeding slide plate 1, and a stepper motor 3 and a stepper motor 4 respectively installed at the other end of the feeding slide plate 1.

[0025] An output wheel 5 is mounted on the output shaft of the stepper motor 3. A slider 6 is set at the eccentric part of the output wheel 5. A connecting part 7 is formed at the other end of the feeding slide plate 1. A groove 8 is opened in the connecting part 7 for the slider 6 to slide, so as to realize the feeding action of the feeding slide plate 1 in the Y-axis direction, that is, to control the left and right swing of the feeding slide plate.

[0026] The output shaft of the stepper motor 24 is equipped with an output wheel 2 9. The eccentric part of the output wheel 2 9 is hinged to a feeding link 10. The other end of the feeding link 10 is hinged to the mounting seat 11 in the middle of the feeding slide plate 1, so as to realize the feeding action of the feeding slide plate 1 in the X-axis direction, that is, to control the forward and backward movement of the feeding slide plate.

[0027] This utility model, through the design of dual stepper motors, can control the forward and backward and left and right movements of the feeding plate separately. Compared with the prior art, which requires two motors to run simultaneously, the control is more flexible. Stepper motor 3 can run independently to control the feeding action of the feeding slide 1 in the Y-axis direction, and stepper motor 2 can run independently to control the feeding action of the feeding slide 1 in the X-axis direction, making the structure more streamlined.

[0028] Combination Figure 2 and Figure 3The feeding slide plate 1 has a strip-shaped guide hole 12 at one end, and a slider 2 13 is arranged in the strip-shaped guide hole 12. A limit piece 14 is arranged on the upper end surface of the slider 2 13. A fixing member 15 is installed in the slider 2 13. The lower end of the fixing member 15 is fixedly connected to the machine body. A bushing is arranged between the fixing member 15 and the slider 2 13. When the stepper motor 3 drives the feeding slide plate 1 to move through the slider 1 6, the other end of the feeding slide plate 1 is sleeved on the outer periphery of the bushing through the slider 2 13, so the feeding slide plate 11 can realize the feeding action in the Y-axis direction. When the stepper motor 4 drives the feeding slide plate 1 to move through the feeding connecting rod 10, the other end of the feeding slide plate 1 is sleeved on the outer periphery of the slider 2 13 through the strip-shaped guide hole 12, and the other end of the feeding slide plate 1 is sleeved on the outer periphery of the slider 1 6 through the slide groove 1 8, so the feeding slide plate 1 can realize the feeding action in the X-axis direction.

[0029] Combination Figure 1 and Figure 4 It also includes a wire cutting assembly 16, a pressure foot lifting assembly, and a stepper motor 17 for driving the wire cutting assembly 16 and the pressure foot lifting assembly to perform actions.

[0030] See details Figure 4 The output shaft of the stepper motor 17 is equipped with a drive wheel 18. The drive wheel 18 is respectively formed with a wire-cutting cam 19 and a pressure foot lifting cam 20. The wire-cutting cam 19 is used to drive the wire-cutting assembly 16 to perform the wire-cutting action, and the pressure foot lifting cam 20 is used to drive the pressure foot lifting assembly to perform the lifting and pressing action.

[0031] See details Figure 4 A wire-cutting drive rod 21 is provided on one side of the wire-cutting cam part 19. The other end of the wire-cutting drive rod 21 is connected to a wire-cutting connecting rod 22. The other end of the wire-cutting connecting rod 22 is connected to a wire-cutting push rod 23. The other end of the wire-cutting push rod 23 is provided with a wire-cutting assembly 16.
