Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a laser marking clamp used for bottles. Background Art

[0002] Before the bottles filled with products are packed, they need to be marked with laser coding equipment to mark the production date and expiration date and to prevent counterfeiting. Bottles are usually divided into bottle caps and bottle bodies. Since the positions of laser coding equipment on different bottles are different, laser coding equipment often needs to use a fixture to position the bottle and print the required icons at the appropriate position.

[0003] At present, the laser marking fixture used for bottles in the prior art is shown in the Chinese invention application "Online laser inner engraving and marking anti-counterfeiting equipment for the inner surface of a transparent wine bottle with a clamp" with patent number CN201010297823.7 (application publication number CN101982317A). The equipment includes a first bracket provided with a transparent wine bottle transmission device and a first bracket provided with a laser. A transverse clamp and a limit clamp are provided on both sides of the transparent wine bottle transmission device. The clamping block of the transverse clamp can clamp the bottle body, and the clamping block of the limit clamp can clamp the bottleneck. Under the action of the clamping block of the transverse clamp and the clamping block of the limit clamp, the clamped transparent wine bottle is tilted and placed on the bracket next to the transparent wine bottle transmission device, thereby completing the marking.

[0004] Although the clamp in the above-mentioned marking device can clamp the bottle, in practice, the sizes of bottles of different models are different. The clamp block of the transverse clamp in the above-mentioned marking device can only clamp bottles of the same size, and the transverse clamp cannot adjust the clamping position according to bottles of different sizes, that is, the laser marking clamp cannot be adjusted to a suitable clamping position in the horizontal and vertical directions, resulting in the bottle being unable to be clamped in the laser marking clamp, and thus making it impossible to mark the bottle; and the clamp in the above-mentioned marking device cannot adjust the clamping degree. If the clamp clamps a bottle of smaller size, the bottle will be unstable in the clamp when the bottle is laser marked, resulting in the position of the bottle marking being offset or the bottle being unable to be marked. For this reason, further improvements need to be made to the laser marking clamp applied to bottles. Summary of the invention
