Description

Technical Field

[0001] This utility model belongs to the field of laser marking devices, specifically relating to a laser marking device for the surface of a packaging box. Background Technology

[0002] In the production process of packaging boxes, in order to give the packaging boxes more information display functions, such as product name, specifications, production date, anti-counterfeiting marks, etc., it is often necessary to mark them on the surface. Traditional marking methods, such as ink printing, have problems such as easy fading, low clarity, and poor environmental protection. However, laser marking technology has gradually become the mainstream technology for marking the surface of packaging boxes due to its advantages such as clear and durable marking, no pollution, high precision, and strong flexibility.

[0003] Most laser marking equipment for packaging boxes on the market can only mark a single surface of the packaging box. If multiple surfaces need to be marked, manual flipping is required, which is not only inefficient, but also prone to inaccurate marking position due to human error. To solve the above problems, a laser marking device for the surface of packaging boxes is proposed. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-3 This utility model provides a laser marking device for the surface of a packaging box, including two conveyors 1 and a frame 2 disposed between the two conveyors 1;

[0026] Rotating component 3 is mounted on frame 2;

[0027] Power mechanism 4 is located on the side of frame 2 and connected to rotating component 3; power mechanism 4 is used to provide power to rotating component 3.

[0028] The second power mechanism 5 is mounted on the rotating component 3;

[0029] Two telescopic components 6 are mounted on the power mechanism 2 5;

[0030] The second power mechanism 5 is used to drive the two telescopic parts 6 to clamp the packaging box through the telescopic parts 6;

[0031] Rotating component 3 is used to drive power mechanism 2 5, telescopic component 6 and packaging box to flip over;

[0032] Two laser marking machines 7 are respectively installed on two conveyors 1;

[0033] Infrared sensor 8 is installed on the right conveyor 1 and is used to detect the passing packaging boxes.

[0034] In this embodiment, before use, the equipment is connected to the power and air supply, and the parameters of the laser marking machine 7 are set, such as laser power, marking speed, and pattern content. The packaging box to be marked is placed on the right conveyor 1. The conveyor 1 is started, which drives the packaging box to the left and performs the marking operation through the laser marking machine 7 on the right. When the packaging box passes the infrared sensor 8 on the right conveyor 1, the infrared sensor 8 detects the packaging box and transmits the signal to the control system of the equipment. After receiving the detection signal, the control system clamps and fixes the packaging box through the cooperation between the second power mechanism 5 and the telescopic component 6. The first power mechanism 4 and the rotating component 3 will drive the packaging box to flip over. After the flipping is completed, the second power mechanism 5 is activated again, causing the clamping plate 63 to release the packaging box and transport it through the left conveyor 1 so that the laser marking machine 7 on the left can perform the laser marking operation on the packaging box. Through the above steps, the packaging box can be automatically flipped over and marked on both sides. Compared with the manual flipping method, it is more efficient and the marking position is more accurate.

[0035] Specifically, refer to Figure 2 The rotating assembly 3 includes two upright plates 31 respectively mounted on the frame 2; a rotating rod 32 rotatably passing through the upright plates 31 at both ends; a gear 33 mounted at one end of the rotating rod 32; a gear 34 rotatably mounted on the outer wall of one of the upright plates 31, the two gears 33 meshing with each other; and a fixing frame 35 sleeved on the outer wall of the rotating rod 32.

[0036] Specifically, refer to Figure 2 The power mechanism 4 includes a pneumatic push rod 42 hinged to the outer wall of the frame 2 via a rotating shaft 41; and a hinge rod 43 hinged to the push shaft of the pneumatic push rod 42, which is connected to the gear 34.

[0037] In this embodiment, after the packaging box is clamped and fixed, the pneumatic push rod 42 in the power mechanism 4 is activated. The pneumatic push rod 42 drives the gear 34 to rotate through the hinge rod 43. Since the two gears 33 mesh with each other and the gears 33 are connected to the rotating rod 32, and the rotating rod 32 is fitted with a fixing frame 35, the power mechanism 5, the telescopic component 6 and the packaging box are connected to the fixing frame 35, the rotating rod 32 will drive the entire assembly to rotate, thereby turning the packaging box over.

[0038] Specifically, refer to Figure 3The second power mechanism 5 includes a clamping frame 51 disposed on the outer wall of the fixed frame 35; a transmission rod 52 and two threaded rods 53 rotatably disposed inside the clamping frame 51; bevel gears 54 disposed at both ends of the transmission rod 52 and one end of the threaded rod 53, with adjacent bevel gears 54 meshing with each other; two moving blocks 55 respectively threadedly sleeved on the outer wall of the threaded rod 53; a hinge seat 56 disposed on the moving block 55; and a servo motor 57 disposed on the outer wall of the clamping frame 51 and whose output end is connected to the other end of one of the threaded rods 53.

[0039] Specifically, refer to Figure 3 The telescopic component 6 includes two connecting rods 61 that are respectively hinged to two opposite hinge seats 56; a second hinge seat 62 that is hinged to the other end of the connecting rods 61; and a clamping plate 63 disposed on the two second hinge seats 62.

[0040] In this embodiment, after the control system receives the detection signal, it starts the servo motor 57 in the second power mechanism 5. The servo motor 57 rotates and drives the threaded rod 53 connected to it to rotate. Since the adjacent bevel gears 54 mesh with each other, the transmission rod 52 and the other threaded rod 53 will also rotate. When the two threaded rods 53 rotate, the moving block 55 sleeved on its outer wall will move towards or away from each other under the action of the thread. The hinge seat 56 on the moving block 55 drives the hinge seat 62 and the clamping plate 63 to move through the connecting rod 61, thereby realizing the clamping and fixing of the packaging box by the two clamping plates 63.

[0041] 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.
