Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, and in particular to a laser engraving device for wine bottles. Background Technology

[0002] Laser engraving technology is widely used for surface processing of various materials due to its advantages such as high precision, high efficiency, and non-contact processing, including engraving patterns, text, or logos on glass bottles.

[0003] Utility model disclosure CN222725770U discloses a bottle neck engraving machine, including an upper body, a lower body, an engraving mechanism, a positioning and clamping mechanism, a conveying mechanism, and multiple mounting mechanisms. The upper body is fixedly connected to the lower body. The engraving mechanism is located inside the upper body and includes a laser pointer. The engraving mechanism drives the laser pointer to emit laser light and to move the laser pointer horizontally. The mounting mechanism includes a support component, a first mounting mold, and a second mounting mold. The support component supports the first mounting mold, the second mounting mold, and the bottle. The positioning and clamping mechanism is located on the upper body and is used to clamp the first mounting mold, the second mounting mold, the bottle, and the bottle. The positioning and clamping mechanism is also used to drive the bottle to rotate. The conveying mechanism is located on the lower body and includes a conveyor belt with multiple positioning rods on it. The positioning rods are used to fix the mounting mechanisms.

[0004] After searching, it was found that the existing technology has certain defects. Its positioning and clamping mechanism requires two sets of chuck structures to clamp the special installation molds at both ends of the bottle. The installation and positioning process is relatively complicated and cumbersome. Each clamping requires adjustment of the mold and chuck, which takes up a lot of production time and seriously affects the overall engraving efficiency. Therefore, a bottle laser engraving equipment is needed to meet people's needs. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 A laser engraving device for wine bottles includes a body 1, a transverse moving mechanism 2 inside the body 1, a laser engraving device 3 connected to the transverse moving mechanism 2, a first servo motor 4 inside the body 1, a bidirectional screw 5 connected to the output shaft of the first servo motor 4, a first moving frame 6 and a second moving frame 7 connected to the bidirectional screw 5, the first moving frame 6 and the second moving frame 7 being arranged symmetrically and parallel to each other, and a rotating roller 8 rotatably connected to both the first moving frame 6 and the second moving frame 7, the rotating roller 8 on the first moving frame 6 being driven and connected by a second servo motor 9.

[0016] Specifically, in this embodiment, the first movable frame 6 is provided with a positive thread hole that matches the positive thread section of the bidirectional screw 5, and the second movable frame 7 is provided with a negative thread hole that matches the negative thread section of the bidirectional screw 5, so as to ensure that when the bidirectional screw 5 rotates, it can reliably drive the first movable frame 6 and the second movable frame 7 to move synchronously towards or away from each other.

[0017] Specifically, in this embodiment, each of the two rotating rollers 8 is provided with a number of equally spaced first rubber wheels 10. The first rubber wheels 10 increase the friction with the bottle body, ensuring that the bottle can rotate stably with the rotating rollers 8 without slipping, and to a certain extent restricting the axial position of the bottle. At the same time, the rubber material is relatively soft, which can effectively avoid causing hard scratches to the surface of the glass bottle.

[0018] Specifically, in this embodiment, the machine body 1 is provided with two ear plates 11, which are respectively arranged on the opposite sides of the first movable frame 6 and the second movable frame 7. A guide rod 12 is provided between the two ear plates 11. The guide rod 12 is arranged parallel to the bidirectional screw 5. The first movable frame 6 and the second movable frame 7 are slidably connected to the guide rod 12. The guide rod 12 provides reliable guidance and support for the first movable frame 6 and the second movable frame 7, preventing them from deflecting or jamming during movement, and ensuring the stability and accuracy of the clamping movement.

[0019] Specifically, in this embodiment, accordion sleeves 13 are provided between the two ear plates 11 and the side adjacent to the first movable frame 6 and the second movable frame 7, as well as between the side adjacent to each other of the first movable frame 6 and the second movable frame 7. The accordion sleeves 13 can enclose the bidirectional screw 5, effectively preventing dust and debris generated by laser engraving from entering the transmission system and extending the service life of the equipment.

[0020] Specifically, in this embodiment, a support plate 14 is provided on the side wall inside the machine body 1, a cylinder 15 is provided on the top of the support plate 14, a pressure plate 16 is connected to the bottom of the telescopic shaft of the cylinder 15, and two connecting rods 17 are provided on the side of the pressure plate 16. The two connecting rods 17 are arranged at an angle and their ends are rotatably connected to a second rubber wheel 18. The second rubber wheel 18 is arranged at the symmetrical center of the first moving frame 6 and the second moving frame 7. After the wine bottle is placed on the rotating rollers 8 on both sides, it is driven down by the cylinder 15 to make the two second rubber wheels 18 contact the bottle body from the top sides of the wine bottle, further ensuring the stability of the wine bottle during the engraving process and preventing axial movement. This is suitable for processing slender wine bottles.

[0021] During operation, the operator places the bottle horizontally into the machine body 1, positioning it between two rotating rollers 8. If the gap between the two rotating rollers 8 is insufficient to support the bottle, the first servo motor 4 is activated to drive the bidirectional screw 5 to rotate, causing the first moving frame 6 and the second moving frame 7 to move towards each other until the first rubber wheels 10 on both sides slightly lift the bottle. Subsequently, the cylinder 15 is activated to drive the pressure plate 16 to move downwards, and the two second rubber wheels 18 press the bottle body from both sides above the bottle via the connecting rod 17, achieving auxiliary positioning. During engraving, the second servo motor 9 is activated to drive the rotating rollers 8 at the first moving frame 6 to rotate, thereby causing the clamped bottle to rotate uniformly around its own axis. At the same time, the horizontal moving mechanism 2 drives the laser engraving device 3 to move along the bottle axis. The two work together to engrave the predetermined pattern or text on the surface of the bottle.

[0022] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
