Description

Technical Field

[0001] The utility model relates to the technical field of button processing, in particular to a feeding device for button processing. Background Art

[0002] In ancient Rome, buttons were originally used as decorations, while brooches were used to fasten clothes. In the 13th century, buttons played the same role as they do today. At that time, people knew how to make buttonholes on clothes, which greatly improved the practical value of buttons. In the 16th century, buttons became popular. With the rise of fast fashion, buttons have changed from functional to creative; they have begun to become clothing decorations. Button stamping is one of the steps in producing buttons.

[0003] Patent document CN212949308U discloses a feeding device for button punching equipment, which is used to solve the technical problem that the length of the material released during the punching process is not suitable, resulting in an unsatisfactory punching effect. It includes a bracket, a coiling device, the coiling device is installed on the bracket, the feeding device also includes a buffer device, the buffer device is installed on the bracket, the buffer device includes a bottom plate, a symmetrically arranged first guide device and a second guide device, and a pressing device for caching a section of material strip, the pressing device and the guide device are both fixed on the bottom plate, the bottom plate is fixed on the coiling device, and the pressing device is arranged in the middle of the guide device; the material strip is wound on the coiling device and passes through the first guide device, the pressing device and the second guide device in turn. Under the action of the buffer device, the length of the material strip released is moderate and will not fall to the ground, thereby ensuring the punching effect. The utility model is easy to operate and is mainly used for the production of buttons.

[0004] In the above scheme, the size of the empty space in the center of the material belt is greatly restricted. The size of the empty space in the center of the material belt needs to be consistent with the size of the wheel of the device. Otherwise, when the motor rotates, the material belt cannot rotate synchronously with the wheel due to its vertical placement under its own gravity, resulting in unstable output rate of the material belt, which will affect the stamping effect. If the material belt is wrapped around the impeller, the workload is large and the efficiency is low. In addition, the buffer device has repeated functions and is relatively complex and occupies space. Therefore, it is necessary to provide a feeding device for button processing to solve the shortcomings of the prior art. Utility Model Content

[0038] Embodiment 1:

[0039] In this embodiment, if Figure 1-3 As shown, the utility model proposes a feeding device for button processing, including a frame 1, one side of the frame is respectively provided with a first connecting rod 11, a second connecting rod 12 and a third connecting rod 13 from top to bottom, and also includes a winding unit, a cache unit and a guide unit, the winding unit is connected to the frame through the third connecting rod, the winding unit has a material belt installation space and a limiting function; the cache unit is connected to the frame through the second connecting rod, and the cache unit is used to cache a feeding stroke of a material belt; the guide unit is connected to the frame through the first connecting rod, and the guide unit is used for traction and guidance of material belt feeding.

[0040] In this embodiment, it is further configured that the coil unit includes a chassis 21, a rotating shaft 22, a turntable 23, a motor 24, a connecting portion 25 and a pressure cover component 26. The bottom surface of the chassis is connected to the end of the third connecting rod, and the chassis plays a supporting role; the rotating shaft is arranged at the center of the chassis, and the rotating shaft passes through the center of the chassis; the turntable is arranged above the chassis, and the turntable is sleeved on the rotating shaft, and the turntable rotates synchronously with the rotating shaft; the motor is fixedly arranged below the chassis, and the output end of the motor is connected to the rotating shaft, and the motor is used to drive the rotating shaft to rotate; the bottom of the connecting portion is connected to the top of the rotating shaft; the bottom of the pressure cover component is connected to the top of the connecting portion, and the pressure cover component is used to limit the material belt.

[0041] In this embodiment, it is further configured that an outer limit groove 231 and an inner limit groove 232 are symmetrically provided on the surface of the turntable, a spring 233 is connected to the outer limit groove on the side close to the center of the turntable, an outer limit block 234 is provided on the side of the spring away from the center of the turntable, a sponge pad 235 is adhered to the top of the outer limit block toward the center of the turntable, the sponge pad can be used for buffering, and can also wipe off dust and oil stains on the surface of the material belt; the inner limit groove is provided with a sliding rod 236, an inner limit block 237 is sleeved on the sliding rod, a buffer pad 238 is adhered to the top of the inner limit block away from the center of the turntable, the bottom of the inner limit block is rough, the friction resistance with the inner limit groove is large, and it is not easy to move, thereby preventing the inner limit block from retreating inward during the conveying process of the material belt.

[0042] In this embodiment, it is further configured that an external thread is provided on the top of the connecting part, an internal thread matching the external thread on the top of the connecting part is provided on the bottom of the pressure cover component, the connecting part is threadedly connected to the pressure cover component, and downward hooks 261 are provided at intervals of 60° on the top of the pressure cover component. The hooks can not only prevent the material belt from loosening upwards, but also prevent the material belt from loosening outwards.

[0043] In this embodiment, the cache unit includes a cache bracket 31 and a cache roller 32. The bottom of the cache bracket is connected to the second connecting rod. The middle of the cache bracket is hollow and passed through by the material belt. The cache roller is arranged on the vertical rods on both sides of the cache bracket. The cache roller is covered with a sponge pad, which can be used for buffering and can also wipe dust and oil stains on the surface of the material belt.

[0044] In this example, the second connecting rod is a metal round rod, which is thinner and has a certain elasticity. When the traction coil is shorter during the conveying process of the material belt, the coil will exert a pulling force on the buffer bracket and the second connecting rod.

The sensing unit is not only used to sense whether the material belt passes through, but can also cooperate with the guide roller to make the material belt more stable when passing through the guide roller and the sensing unit, with less up and down shaking, and can also allow the dust or oil stains on the bottom surface of the material belt to be wiped off by the sponge pad on the guide roller.

[0047] Embodiment 2:

[0048] In this embodiment, if Figure 4 As shown, the difference from Example 1 is that the cover component is a cover plate, which is used to prevent the material belt from loosening upwards. Compared with a plurality of hooks, the cover plate is relatively bulky, and it is impossible to see whether the material belt is loosening outwards, and it is also unable to further prevent the material belt from loosening outwards.

[0049] The working principle of the feeding device for button processing is to install the material belt on the turntable, and pull the two symmetrical outer limit blocks and the sponge pads thereon to fit the outer side of the material belt, move the two symmetrical inner limit blocks and the buffer pads thereon to fit the inner side of the material belt, thread the cover component and the connecting part, pull the material belt coil through the middle of the buffer bracket, and fold the material belt coil from vertical to horizontal to pass through the cavity formed between the guide roller and the guide component, and then pass through the chuck on the frame to reach the bottom of the punching machine, start the motor to drive the turntable, so that the material belt can be transported in the direction of product production.
