[0019] The embodiments of the present application are described in detail below, but the present application can be implemented in many different ways as limited and covered by the claims.

[0020] As an aspect of the present application, a buffering mechanism for a buttoning machine to prevent plastic button burst is provided, comprising: a lifting driving part, a buffering sliding block 1, a connecting rod 2 and a buffering spring 3, the connecting rod 2 is provided with a buffering sliding groove 4, the buffering sliding block 1 is slidably arranged in the buffering sliding groove 4, the lifting driving part is connected with the buffering sliding block 1 and drives the connecting rod 2 to move up and down through the buffering sliding block 1, the lower end of the connecting rod 2 is provided with an upper die assembly, the lower end of the upper die assembly is provided with a punch pin 5, one side of the buffering sliding block 1 is provided with a buffering rod 6, the buffering spring 3 is sleeved on the buffering rod 6, and one end of the buffering spring 3 abuts against the connecting rod 2.

[0021] Please refer to Figure 3 and Figure 4 In one embodiment, the buttoning machine with the buffering mechanism of the buttoning machine in the present application comprises a base 28, and the buffering mechanism of the buttoning machine is arranged above the base 28. A lower button feeding mechanism 24 and an upper button feeding mechanism 25 are arranged on both sides of the buffering mechanism of the buttoning machine, which belong to conventional mechanisms in the prior art and will not be described again. One side of the base 28 is provided with a maintenance plate 29 for maintenance, and the maintenance plate 29 can be opened to facilitate maintenance; a tool box 30 is further arranged at the upper end of the base 28, and some general sundries and tools can be placed in the tool box 30 after the door of the tool box 30 is opened; a heat dissipation port 32 for heat dissipation is further arranged at the rear side of the base 28. For example, a material cleaning part 31 can be arranged at the material bin of the lower button feeding mechanism 24 and the upper button feeding mechanism 25 to take out the material in the material bin which is not used up or has defects.

[0022] The lower button feeding mechanism 24 and the upper button feeding mechanism 25 are powered by a driving motor 34 with double output shafts, and the lower button feeding mechanism 24 and the upper button feeding mechanism 25 are synchronously driven by belt transmission to work, so that the lower button output by the lower button feeding mechanism 24 is conveyed to the lower die assembly 20 through the lower button feeding slide 26, and the upper button output by the upper button feeding mechanism 25 is conveyed to the upper die assembly through the upper button feeding slide 27. Then, under the action of the push arm 21 with a U-shaped notch, the material pushing part 19 is pushed forward, so that the material pushing part 19 positions the upper button and the lower button to the predetermined positions respectively to realize the alignment of the two.

[0023] The pushing arm 21 can be pressed down by the driving rod connected with the connecting rod 2, so that the pushing arm 21 rotates around its rotation axis, and the U-shaped notch on the pushing arm 21 pushes the pushing part 19 forward. In addition, a handle 23 matched with the pushing arm 21 can be arranged, so that the pushing part can be positioned manually through the handle 23. When the positioning is completed, the pushing arm 21 is pulled back to the initial position under the action of the reset spring 22, and the reset is realized.

[0024] In the process of stamping, please refer to Figure 1 and Figure 2 The lifting driving part drives the buffer sliding block 1 to move downward. Since the buffer sliding block 1 is provided with the buffer rod 6, and the buffer rod 6 is provided with the buffer spring 3, the lower end of the buffer spring 3 abuts against the connecting rod 2. Therefore, the connecting rod 2, the upper die assembly and the punch 5 can move downward under the action of the buffer spring 3. When the upward pressing force applied by the punch 5 exceeds the buffer force provided by the buffer spring 3, the buffer spring 3 is compressed, and the buffer sliding block 1 can still move downward along the buffer sliding groove 4 on the connecting rod 2 under the action of the lifting driving part, so that the purposes of buffering and pressure relief are achieved, so as to minimize the pressure applied to the upper buckle and avoid the explosion of the upper buckle due to excessive stamping force.

[0025] Preferably, the buffer rod 6 is movably arranged in the through hole of the connecting rod 2, and the end of the buffer rod 6 away from the connecting rod 2 is provided with a spring positioning member 7, and the other end of the buffer spring 3 abuts against the spring positioning member 7. The spring positioning member 7 can be a nut or the like, so that the size of the buffer force can be adjusted through the spring positioning member 7 to adapt to different specifications of the upper buckle.

[0026] Preferably, the lifting driving part includes an eccentric driving mechanism 8 and a motor 9, and the motor 9 drives the buffer sliding block 1 to move upward and downward through the eccentric driving mechanism 8. For example, the motor 9 can drive the buffer sliding block 1 to move upward and downward through the reducer 17 connected with the eccentric driving mechanism 8. The eccentric driving mechanism 8 can adopt a mechanism known in the art, which will not be described here.

[0027] Preferably, the upper die assembly comprises an upper die slider 10 and an upper buckle clamp 11, the upper die slider 10 is connected with the connecting rod 2, one side of the upper die slider 10 is provided with an upper buckle clamp fixing rod 12, the upper buckle clamp 11 is provided with a hand pressing prevention sliding groove 13 for the upper buckle clamp fixing rod 12 to pass through, the upper buckle clamp fixing rod 12 is installed with a hand pressing prevention spring 14, and the upper buckle clamp 11 is in abutment with the upper die slider 10 through the hand pressing prevention spring 14. In this embodiment, if the hand of the operator is accidentally located below the upper buckle clamp 11 during the stamping process, when the upper buckle clamp 11 moves downward and contacts the hand, a resistance is generated to the upper buckle clamp 11. Since the upper buckle clamp 11 is installed on the upper die slider 10 through the upper buckle clamp fixing rod 12 arranged in the hand pressing prevention sliding groove 13, under the action of the resistance, the soft connection structure formed by the hand pressing prevention spring 14 plays a soft connection role, so that the upper buckle clamp 11 no longer moves downward synchronously with the upper die slider 10, thereby avoiding hand pressing.

[0028] For example, two upper buckle supporting parts 18 are arranged at the position corresponding to the upper buckle of the upper buckle clamp 11, and the two upper buckle supporting parts 18 are connected with the upper buckle clamp 11 through spring elements and the like, so as to realize an openable and closable upper buckle supporting structure. When the upper buckle is conveyed to the upper buckle clamp 11 through the upper buckle feeding slide 27, the upper buckle supporting structure is in a closed state to support the upper buckle. During stamping, under the action of the pressure, the upper buckle supporting structure changes from the closed state to an open state, so that the upper buckle moves downward to the cloth and is sleeved on the rivet column of the upper buckle.

[0029] Preferably, the upper die slider 10 is provided with a sensor 15 for detecting the upper buckle clamp 11. Preferably, the sensor 15 is a proximity switch. In this embodiment, when the upper buckle clamp 11 contacts the hand, the upper die slider 10 continues to move downward, so that the upper end of the upper buckle clamp 11 is deviated from the sensor 15, so that the sensor 15 can detect whether the hand pressing phenomenon occurs.

[0030] Preferably, the controller receives a first signal for controlling the lifting driving part to stop moving when the sensor 15 detects that the position of the upper buckle clamp 11 relative to the upper die slider 10 deviates from the predetermined position. For example, if the controller receives the first signal, it means that the hand pressing phenomenon occurs, and the lifting driving part can be stopped.

[0031] Preferably, one side of the upper die slider 10 is provided with a positioning lamp 16. The positioning lamp 16 can emit a light spot such as a red light spot, and the light spot irradiates on the cloth to indicate the approximate position of the buckle to the operator.

[0032] The utility model also provides a kind of to knock the machine for preventing plastic button burst, and the knock machine buffer mechanism of the utility model.

[0033] The above only for the preferred embodiment of the utility model, and is not used to limit the utility model, for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
