Description

Technical Field

[0001] This utility model relates to the field of button machine technology, and in particular to a punch rod buffer for a button machine. Background Technology

[0002] A button-making machine is a device used to fasten buttons onto clothing. It is commonly used in the garment processing industry because it can quickly attach buttons to clothing, greatly improving garment production efficiency, and is therefore widely used.

[0003] Existing button-making machines first punch holes in the corresponding positions of the garment using a punching assembly, and then press the buttons onto the garment using a snap-fit ​​assembly. During the installation process, a stamping component is usually placed above the punching assembly and the snap-fit ​​assembly. The stamping component presses downwards, causing the punching rod in the punching assembly or the snap-fit ​​rod in the snap-fit ​​assembly to move quickly toward the garment (generally, the garment is located directly below the punching assembly) to punch holes or snap buttons onto the garment.

[0004] In existing button machines, the stamping part typically comes into direct contact with the punching rod or pressing rod during punching or pressing operations. Since the stamping part, punching rod, and pressing rod are all made of metal, they are prone to producing a harsh noise when they collide. At the same time, because the stamping part needs to collide with the punching rod and pressing rod frequently during operation, after repeated collisions, the stamping part and the punching rod and pressing rod will experience significant impact wear, causing the stamping part to be dented or the punching rod or pressing rod to be twisted and deformed. Therefore, improvements are needed. Utility Model Content

[0005] The main purpose of this utility model is to provide a punch rod buffer for a button machine, which aims to provide a buffer for cushioning between the punching part and the punching rod or snap button rod.

[0006] To achieve the above objectives, this utility model proposes a punching rod buffer for a button machine, comprising a buffer body, the buffer body including a connecting part and a buffer part, the connecting part and the buffer part being integrally formed, a buffer groove being provided in the middle of the buffer body, an elastic body being provided in the buffer groove, the elastic body extending outside the buffer groove, and the top of the elastic body being higher than or flush with the upper surface of the buffer part.

[0007] Specifically, the connecting part is cylindrical, the buffer part is hexagonal, and the height of the connecting part is greater than the height of the buffer part.

[0008] Specifically, the buffer groove is circular in shape and extends through the entire buffer section and the end of the connecting section that connects to the buffer section. The radius of the circular surface of the portion of the buffer groove located at the connecting section is smaller than the radius of the circular surface of the portion located at the buffer section.

[0009] Specifically, the outer surface of the connecting part is provided with external threads to achieve screwing with the internal threads provided at the external punching rod or snap rod.

[0010] Specifically, the buffer body is made of plastic material.

[0011] Specifically, the corners of the buffer section are provided with downward-sloping arc-shaped anti-scratch surfaces.

[0012] Specifically, the elastomer is cylindrical and is fitted into the buffer groove, with its top end located outside the buffer groove and above the upper surface of the buffer section.

[0013] Specifically, the buffer is made of plastic.

[0014] This utility model's technical solution uses a connecting part to connect with an external punching rod or snap rod, allowing the buffer body to be installed at the end where the external punching rod or snap rod collides with the stamping part. By setting an elastic body in the buffer groove, the elastic body contacts the external stamping part to reduce the impact force. Furthermore, by contacting the stamping part with the buffer body, the impact force of the stamping part on the punching rod or snap rod is buffered, while simultaneously reducing noise generation.

[0025] like Figures 1 to 6As shown, a button machine punching rod buffer includes a buffer body 10. The buffer body 10 includes a connecting part 11 and a buffer part 12, which are integrally formed. A buffer groove 13 is provided in the middle of the buffer body 10. An elastic body 14 is provided in the buffer groove 13. The elastic body 14 extends outside the buffer groove 13, and the top of the elastic body 14 is higher than or flush with the upper surface of the buffer part 12. When punching and snapping buttons are applied to garments, a buffer body 10 is first installed at the end of the punching rod 20 or snapping rod 30 that contacts the stamping part. The buffer body 10 is connected to the end of the punching rod 20 or snapping rod 30 via a connecting part 11. The buffer part 12 contacts the stamping part. A buffer groove 13 is provided in the buffer body 10, and an elastic element extending above the upper surface of the buffer part 12 is provided within the buffer groove 13. When the stamping part impacts the punching rod 20 or snapping rod, the stamping part first contacts the elastic element, which provides initial buffering to reduce the impact force. As the stamping part continues to move, it eventually contacts the buffer part 12. The impact force is driven to the punching rod 20 or the snap-on rod 30 by the buffer part 12. At the same time, it moves downward with the punching rod 20 or the snap-on rod 30, thereby playing a buffering role, avoiding direct contact between the stamped part and the punching rod 20 or the snap-on rod 30, reducing the collision and wear between the stamped part and the punching rod 20 and the snap-on rod 30, and providing buffer protection for the stamped part, the punching rod 20 and the snap-on rod 30, thereby improving the service life of the stamped part, the punching rod 20 and the snap-on rod 30, and reducing the daily maintenance cost of the button machine. In daily use, the buffer part body 10 greatly reduces the noise generated when the stamped part impacts the punching rod 20 or the snap-on rod 30, reducing the physical harm to the operator caused by noise.

[0026] The connecting part 11 is cylindrical, and the buffer part 12 is hexagonal. The height of the connecting part 11 is greater than the height of the buffer part 12. By making the connecting part 11 cylindrical to facilitate connection with the punching rod 20 or the snap rod 30, and by making the buffer part 12 hexagonal, the force-bearing area of ​​the buffer part 12 is increased, thereby improving the buffering effect and providing better protection for the stamped part or the punching rod 20 and snap rod 30.

[0027] The buffer groove 13 is circular in shape and extends through the entire buffer portion 12 and the end of the connecting portion 11 that connects to the buffer portion 12. The radius of the circular surface of the portion of the buffer groove 13 located at the connecting portion 11 is smaller than the radius of the circular surface of the portion located at the buffer portion 12. When installing the elastic element, the lower end of the elastic element is inserted into the buffer groove 13 and abuts against the connecting portion 11. Since the radius of the circular surface of the buffer groove 13 located at the connecting portion 11 is smaller than the radius of the circular surface at the buffer portion 12, the buffer groove 13 forms a deformation space 15 between the connecting portion 11 and the buffer portion 12, which can accommodate the deformation of the elastic element. When the elastic element expands under pressure, the corresponding expansion portion can be contained within the deformation space 15, thereby preventing the elastic element from bursting or popping out of the buffer groove 13 under stress, thus improving the stability of the elastic element within the buffer groove 13.

[0028] The outer surface of the connecting part 11 is provided with external threads to achieve screwing connection with the internal threads provided at the external punching rod 20 or the snap rod 30. By providing external threads on the outer surface of the connecting part 11, a connecting port 40 with internal threads is provided at the end of the punching rod 20 or the snap rod 30. The external and internal threads are engaged to facilitate the installation or removal of the buffer body 10.

[0029] The buffer body 10 is made of plastic material. In this embodiment, the buffer is made of hard plastic to reduce noise when it collides with the stamped part. Alternatively, it can be made of metal, such as copper, iron, or an alloy of other metals, to increase the hardness of the buffer body 10. However, an insulating material needs to be coated on the outer layer of the buffer body 10 to reduce noise during the collision.

[0030] The corners of the buffer section 12 are provided with downward-sloping arc-shaped anti-scratch surfaces 16. By providing anti-scratch surfaces 16, the sharpness of the corners of the buffer section 12 is reduced, avoiding unnecessary damage to the stamped parts or unnecessary injury to the operators.

[0031] The elastic element is cylindrical and is fitted into the buffer groove 13. The top of the elastic element is located outside the buffer groove 13 and higher than the upper surface of the buffer part 12. The buffer element is made of plastic. In this embodiment, a rubber strip is used to support the elastic element to better buffer and protect the stamped part. In addition, other elastic materials can be selected according to requirements.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
