Technical Field

[0001] This application relates to the technical field of button attaching machines, and in particular to a fabric-covering button attaching machine. Background Technology

[0002] A fabric-covered button is a button with fabric covering its outer side. It consists of an upper button, a lower button, and fabric. The fabric covers the end face of the upper button, and the lower button presses the edge of the fabric against the back of the upper button. During production, the lower button is riveted to the back of the upper button using a stamping process.

[0003] Currently, Chinese patent application number 202010051628X discloses a fabric fastener machine, including a frame and a worktable mounted on the frame. A stamping die that can move up and down is provided on the frame above the worktable. An upper fastener die, a lower fastener die, and a pressing fastener die are provided on the worktable. A driving component is installed on the frame. The driving end of the driving component is connected to the worktable and drives the worktable to swing back and forth. The upper fastener die, lower fastener die, and pressing fastener die can all be moved to directly below the stamping die by the swinging of the worktable.

[0004] When making the fabric-covered button, the upper button is first placed in the upper button mold and the lower button is placed in the pressing button mold. Then, the fabric is covered on the upper button end face of the upper button mold. As the stamping action of the stamping die and the drive component drives the worktable to swing, the stamping die first stamps the upper button mold, covering the fabric with the upper button. Then the stamping die stamps the lower button mold, pressing the edge of the fabric tightly against the back of the upper button.

[0005] When the aforementioned fabric button machine is working, the worktable swings back and forth to move directly below the stamping die. Therefore, there is a possibility of misoperation by the operator during the placement of the upper and lower buttons and the fabric, which could cause safety hazards. Thus, there is room for improvement. Utility Model Content

A driving component 5 is mounted on the frame 1 to drive the rotating shaft 4 to rotate. In one embodiment, the driving component 5 is a drive motor, the body of which is fixed to the frame 1 by a bracket, and the output shaft of the drive motor is connected to the rotating shaft 4 via a coupling. The drive motor drives the rotating shaft 4 to rotate, thereby realizing the rotation of the worktable 2 on the frame 1.

[0028] The stamping die 3 is positioned above the worktable 2 and can move up and down. At least two sets of fastening modules 6 are provided on the worktable 2. In one embodiment, two sets of fastening modules 6 are provided, and the two sets of fastening modules 6 are arranged along the circumferential direction of the worktable 2.

[0029] Reference Figure 2 and Figure 3 As shown, the fastening module 6 includes an upper fastening mold 7, a lower fastening mold 8, and a lower fastening mold 9. The upper fastening mold 7, the lower fastening mold 8, and the lower fastening mold 9 are distributed at intervals along the circumferential direction with the worktable 2 as the center. The worktable 2 moves the upper fastening mold 7, the lower fastening mold 8, and the lower fastening mold 9 to below the stamping mold 3 in sequence by rotating.

[0030] In this application, the workbench 2 is equipped with two sets of button-attaching modules 6. By placing the upper button in the upper button-attaching mold 7 and the lower button in the lower button-attaching mold 8, and placing the fabric in the upper button-attaching mold 7 and covering the upper button, the workbench 2 rotates to sequentially send the upper button-attaching mold 7, the lower button-attaching mold 8 and the lower button-attaching mold 9 into the lower part of the stamping mold 3 to complete the production of the fabric-covered button. Thus, when one set of button-attaching modules 6 is working, the worker can place the upper button, the lower button and the fabric in the other set of button-attaching modules 6, so that the worker can avoid the upper and lower stamping range of the stamping mold 3, thereby reducing the possibility of misoperation and reducing safety hazards.

In one embodiment, the stamping anti-detachment part includes an anti-detachment groove 35 on the stamping sleeve 31 and a stamping anti-detachment screw 36 threaded into the anti-detachment groove 35. The side wall of the stamping die post 32 has a stamping anti-detachment groove 37 along its axial direction, and the end of the stamping anti-detachment screw 36 extends into the stamping anti-detachment groove 37. By providing the stamping anti-detachment part, the stamping sleeve 31 can be prevented from detaching from the stamping die post 32 when it moves up and down along the stamping die post 32.

[0032] The frame 1 is equipped with a stamping drive 5 above the worktable 2. The stamping die 32 is fixed to the stamping drive 5 by screws. The stamping drive 5 can be a cylinder, a hydraulic cylinder or an electric push rod. The stamping drive 5 is used to realize the up and down movement of the stamping die 3.

[0033] Reference Figure 5 As shown, the upper buckle mold 7 includes an upper buckle base 71, an upper buckle top post 72, an upper buckle mold base 73, and an upper buckle spring 74. The upper buckle base 71 is fixedly mounted on the workbench 2. The upper buckle top post 72 is fixed vertically in the upper buckle base 71. An upper buckle mounting port 75 is provided through the middle of the upper buckle mold base 73. The upper buckle mold base 73 is slidably sleeved on the upper buckle top post 72 through the mounting port. The upper end of the upper buckle top post 72 is flush with the surface of the upper buckle mold base 73. An upper buckle receiving groove 76 is formed between the side wall of the upper buckle top post 72 and the upper buckle mold base 73. The upper buckle spring 74 is installed between the upper buckle base 71 and the upper buckle mold base 73. The elastic force of the upper buckle spring 74 is less than the elastic force of the stamping spring 34.

[0034] It is worth noting that the side wall of the upper buckle top column 72 is provided with an upper buckle anti-detachment groove 77 along its axial direction, and an upper buckle anti-detachment screw 78 is threaded in the upper buckle mold base 73. The end of the upper buckle anti-detachment screw 78 extends into the upper buckle anti-detachment groove 77, so as to achieve the function of preventing the upper buckle mold base 73 from detaching during the up and down lifting.

[0035] Reference Figure 6As shown, the buckle mold 8 includes a buckle base 81, a buckle top post 82, a buckle mold base 83, and a buckle spring 84. The buckle base 81 is fixedly mounted on the workbench 2. The buckle top post 82 is fixedly mounted vertically in the buckle base 81. A buckle mounting port 85 is provided through the middle of the buckle mold base 83. The buckle mold base 83 is slidably sleeved on the buckle top post 82. The upper end of the buckle top post 82 is lower than the surface height of the buckle mold base 83. A buckle receiving groove 86 is formed between the upper end of the buckle top post 82 and the buckle mold base 83. The buckle spring 84 is installed between the buckle base 81 and the buckle mold base 83. The elastic force of the buckle spring 84 is greater than the elastic force of the stamping spring 34.

[0036] The top surface of the lower buckle top post 82 is provided with an arc-shaped surface 87, which is used to fit the lower buckle and improve the placement stability of the lower buckle. The lower buckle top post 82 has a through hole 88 extending along its axial direction. When the lower buckle is placed on the top of the lower buckle top post 82, the through hole 88 can prevent the lower buckle from being attracted to the top of the lower buckle top post 82.

[0037] It is worth noting that the side wall of the lower buckle top column 82 is provided with a lower buckle anti-detachment groove 89 along its axial direction, and a lower buckle anti-detachment screw 90 is threaded in the lower buckle mold base 83. The end of the lower buckle anti-detachment screw 90 extends into the lower buckle anti-detachment groove 89, so as to achieve the function of preventing the lower buckle mold base 83 from detaching during up and down lifting.

[0038] Reference Figure 2 As shown, the snap-down die 9 includes a snap-down base 91 and a snap-down sleeve 92. The snap-down base 91 is fixedly mounted on the worktable 2, and the snap-down sleeve 92 is fixed vertically on the snap-down base 91. A snap-down opening 93 is provided through the snap-down sleeve 92, the snap-down base 91, and the worktable 2. A snap-down channel 94 is provided on the frame 1, directly opposite the stamping die column 32.

[0039] Reference Figure 7 and Figure 8 As shown, by placing the upper buckle in the upper buckle mold 7, the upper buckle is fitted onto the upper end of the upper buckle top post 72 and housed in the upper buckle receiving groove 76.

[0040] The lower buckle is placed in the lower buckle mold 8 and is housed in the lower buckle receiving groove 86.

[0041] The fabric is placed in the upper buckle mold 7 and covered on the upper buckle.

[0042] The worktable 2 rotates to first send the upper buckle mold 7 into the lower part of the stamping mold 3. The stamping mold 3 moves down and the stamping sleeve 31 abuts against the upper buckle mold base 73. Since the elastic force of the upper buckle spring 74 is less than that of the stamping spring 34, the upper buckle spring 74 contracts. The upper buckle is pushed into the stamping port 33 of the stamping sleeve 31 by the upper buckle top post 72 along with the fabric. The fabric will partially cover the upper buckle.

[0043] Subsequently, the worktable 2 rotates to send the lower buckle mold 8 under the stamping mold 3. The stamping mold 3 moves down, and the stamping sleeve 31 abuts against the lower buckle mold base 83. Since the elastic force of the lower buckle spring 84 is greater than the elastic force of the stamping spring 34, the stamping spring 34 contracts. The upper buckle, along with the fabric, is pushed out by the stamping mold column 32 and pushed into the lower buckle receiving groove 86. The lower buckle presses the edge of the fabric against the back of the upper buckle. The lower buckle, the fabric, and the upper buckle form a fabric-covered buckle that is received in the lower buckle receiving groove 86.

[0044] As the stamping die 3 continues to press down, the stamping sleeve 31 reaches its maximum downward stroke. At this time, the lower buckle spring 84 will retract, and the lower buckle top post 82 will push out the fabric buckle and receive it into the stamping port 33.

[0045] Subsequently, the workbench 2 rotates to send the buckle-down mold 9 under the stamping mold 3. The buckle-down opening 93 and the buckle-down channel 94 are opposite each other. The stamping mold 3 moves down, the stamping sleeve 31 abuts against the buckle-down sleeve 92, the stamping spring 34 contracts, and the stamping mold column 32 pushes the fabric buckle out of the stamping opening 33 and drops it into the buckle-down channel 94, where it is collected.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
