Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically to an ultraviolet laser marking machine for use in flexible packaging machines. Background Technology

[0002] Flexible packaging machines are equipment used to automatically process flexible packaging materials (such as plastic film, composite film, aluminum foil, etc.) through bag making, filling, and sealing. They are widely used in packaging production in the food and pharmaceutical industries. They use ultraviolet lasers to generate beams and etch markings on the material surface through a galvanometer system. They are suitable for coding flexible materials and other substrates that are easily damaged by heat. Ultraviolet laser coding machines are usually installed at the conveyor station of the flexible packaging machine (such as after packaging is formed and before sealing).

[0003] Most current UV laser marking machines use conveyor belts to transport packaging bags before marking them. However, wrinkles easily appear at the sealed area of ​​the packaging bags due to uneven material tension and friction during transport. Since marking requires precise alignment with a flat surface, wrinkles prevent the laser beam from fully engaging the target area, resulting in incomplete, blurry, or misaligned markings that affect readability. To address this, we propose a UV laser marking machine specifically designed for flexible packaging machines. Utility Model Content

[0004] The purpose of this invention is to provide a UV laser marking machine specifically for flexible packaging machines, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a UV laser marking machine for flexible packaging machines, comprising a U-shaped mounting frame, wherein an upper support plate and a lower support plate are fixedly connected to the inner top and bottom ends of the mounting frame near the outer side, and the marking machine body is mounted in the middle of the top of the mounting frame;

[0006] Both sides of the upper and lower support plates are rotatably connected to rotating rods. Each rotating rod has a synchronous pulley fixedly connected to one side of its rod wall. A synchronous belt meshes between the two synchronous pulleys. An elastic clamping belt is embedded at the outer end of each synchronous belt. Rubber pressure rollers and metal pressure rollers are fixedly connected to the upper and lower sides of the rotating rod near the synchronous pulleys, respectively. A packaging limiting groove is opened in the middle of the inner side wall of the mounting frame. Several rollers are rotatably connected to the inner wall of the packaging limiting groove. A drive motor is fixedly connected to the upper and lower ends of the outer side wall of the mounting frame, and the output end of each drive motor is fixedly connected to one of the rotating rods.

[0007] Preferably, the coding end of the inkjet printer body is located between the synchronous belt and the inner wall of the mounting frame.

[0008] Preferably, a timing belt limiting disc is fixedly connected to both sides of the timing pulley.

[0009] Preferably, the elastic clamping band is made of either rubber or silicone.

[0010] Preferably, the diameter of the rubber pressure roller and the metal pressure roller is larger than the vertical clamping width between the elastic clamping strip.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the synchronous belt is driven by the synchronous pulley to convey the packaging bag, the elastic clamping belt (rubber or silicone material) flexibly clamps the edge of the packaging bag, and the packaging limiting groove and roller limit and guide the packaging bag to ensure accurate coding position and avoid excessive shaking affecting coding. Then, the diameter of the rubber pressure roller and the metal pressure roller is larger than the vertical clamping width, which can fully crush the sealing of the packaging bag, eliminate wrinkles, and solve the problem of incomplete coding.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: A UV laser marking machine for flexible packaging machines includes a U-shaped mounting frame 1. An upper support plate 11 and a lower support plate 12 are fixedly connected to the top and bottom of the mounting frame 1 near the outer side, respectively. The marking machine body 13 is mounted in the middle of the top of the mounting frame 1. The marking end of the marking machine body 13 is located between the synchronous belt 23 and the inner wall of the mounting frame 1.

[0020] In use, the ultraviolet laser marking machine is fixed to the corresponding station of the flexible packaging machine via the mounting frame 1. After the equipment is started, the packaging bags conveyed by the flexible packaging machine are transported along the inside of the mounting frame 1. When the packaging bag passes below the marking end of the marking machine body 13 (located between the synchronous belt 23 and the inner wall of the mounting frame 1), the marking machine body 13 starts and completes the marking operation on the surface of the packaging bag. Subsequent packaging bags continue to be conveyed to the next process.

[0021] Example 2: The technical solution of this example, which differs from that of Example 1, includes: rotating rods 2 are rotatably connected to both sides of the upper support plate 11 and the lower support plate 12; synchronous pulleys 21 are fixedly connected to one side of the rod wall of each rotating rod 2; synchronous belts 23 are meshed between the two synchronous pulleys 21; elastic clamping belts 24 are embedded at the outer ends of the synchronous belts 23; rubber pressure rollers 25 and metal pressure rollers 26 are fixedly connected to the upper and lower ends of the rotating rod 2 near the synchronous pulleys 21, respectively; a packaging limiting groove 101 is opened in the middle of the inner wall of the mounting frame 1; and several... The roller 14 and the synchronous belt pulley 21 are fixedly connected to the synchronous belt limit plate 22 on both sides. The elastic clamping belt 24 is made of rubber or silicone. The diameter of the rubber pressure roller 25 and the metal pressure roller 26 is larger than the vertical clamping width between the elastic clamping belt 24. The larger diameter of the rubber pressure roller 25 and the metal pressure roller 26 than the vertical clamping width between the elastic clamping belt 24 can ensure that the sealing of the packaging bag is fully crushed. The upper and lower ends of the outer wall of one side of the mounting frame 1 are fixedly connected to the drive motor 210, and the output end of the drive motor 210 is fixedly connected to one of the rotating rods 2.

[0022] In use, first install the equipment on the flexible packaging machine, start the drive motor 210 to drive the rotating rod 2 to rotate, the rotating rod 2 drives the synchronous pulley 21 to rotate, and the synchronous belt 23 runs with the synchronous pulley 21. The synchronous belt limit discs 22 on both sides prevent the synchronous belt 23 from deviating. Feed the packaging bag in from the inlet, and the edge of the packaging bag enters between the elastic clamping belts 24 (rubber or silicone material) of the upper and lower synchronous belts 23, where it is flexibly clamped and conveyed forward.

[0023] During the conveying process, the upper and lower rubber rollers 25 and metal rollers 26 first flatten the sealed area of ​​the packaging bag; then the packaging bag enters the packaging limiting groove 101, and the inner wall rollers 14 assist in guiding the conveying, finally completing the printing at the printing end of the inkjet printer body 13, avoiding incomplete printing due to wrinkles.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
