Description

Technical Field

[0001] This utility model belongs to the field of laser engraving technology, specifically an auxiliary device for laser engraving of leather. Background Technology

[0002] Leather laser engraving machines (usually CO2 laser engraving machines) use a high-energy laser beam as the processing medium. Through a numerical control system, the intensity and position of the laser beam on the surface of the leather material are precisely controlled, causing the leather material to undergo physical or chemical changes such as melting, vaporization, or combustion under the action of the laser beam, forming the desired engraved pattern or text, thereby achieving a fine and accurate engraving effect.

[0003] In the existing technology, the leather laser engraving process first fixes the leather in the processing area, and the laser head moves on the leather surface according to a predetermined trajectory and speed. The oil and dust adsorbed on the leather surface can easily generate a lot of smoke during engraving, which is harmful to the health of personnel. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the existing technology by providing an auxiliary device for laser engraving of leather. The invention uses a material-retrieving mechanism to remove cleaning pads from the storage bin, a clamping mechanism to hold both ends of the cleaning pads, and a moving frame to move the cleaning pads across the leather for wiping and cleaning. This effectively removes grease and absorbed dust, reduces fumes generated during engraving, and protects the health of personnel.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an auxiliary device for leather laser engraving, including a movable frame located on a workbench, a storage box and a material picking mechanism on the movable frame, multiple cleaning cotton pads stacked inside the storage box, and a material discharge port at the bottom of the storage box; the material picking mechanism includes a rotating cylinder located below the material discharge port, the rotating cylinder having a groove aligned with the cleaning cotton pads, and clamping mechanisms at both ends of the rotating cylinder.

[0006] Preferably, the groove includes a vertical plane on one side and an arc surface at the bottom, the arc surface being smoothly connected to the outer surface of the rotating cylinder.

[0007] Preferably, the rotating drum is provided with arc-shaped baffles on both sides.

[0008] Preferably, the length of the rotating drum is less than the length of the cleaning cotton pad.

[0009] Preferably, the clamping mechanism includes an upper clamping block and a lower clamping block, the lower clamping block being located at the lower part of the lower side of the rotating cylinder, and the upper clamping block being located at the upper part of the lower side of the rotating cylinder.

[0010] Preferably, the clamping mechanism further includes a connecting plate and a push cylinder, the lower clamping block is fixedly connected to the movable frame, the upper clamping block is connected to the connecting plate, and the connecting plate is connected to one end of the push cylinder.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] (1) The cleaning cotton pad is taken out from the storage box by the material picking mechanism, the clamping mechanism clamps the two ends of the cleaning cotton pad, and the moving frame moves the cleaning cotton pad on the leather to wipe and clean it, removing grease and adsorbed dust, reducing the smoke generated during carving, and protecting the health of personnel.

[0013] (2) The groove includes a vertical plane on one side and an arc surface at the bottom. The vertical plane blocks the cleaning cotton pads that fall into the groove. When the drum rotates, it causes the cleaning cotton pads to rotate downwards. Arc-shaped baffles are provided on both sides of the drum to prevent the cleaning cotton pads from falling.

[0014] (3) The length of the rotating drum is less than the length of the cleaning cotton pad. When it rotates to the lower side, the clamping mechanism can clamp the two ends of the cleaning cotton pad. At this time, the rotating drum reverses and the arc surface gradually presses on the cleaning cotton pad, so that the cleaning cotton pad adheres to the leather and is easy to wipe and clean.
