Description

Technical Field

[0001] This utility model belongs to the field of medical packaging processing technology, specifically relating to a laser coding machine for whole bundles of boxes. Background Technology

[0002] In the food, pharmaceutical, and daily necessities manufacturing industries, product packaging box marking and traceability are key links in ensuring quality and safety and realizing supply chain management. For mass-produced products, individual packaging boxes usually need to be bundled together for warehousing and transportation. Therefore, marking the surface of the bundled boxes (such as production date, batch number, traceability QR code, etc.) has become an indispensable process. Laser marking technology has gradually replaced traditional inkjet marking due to its advantages such as clear marking, wear resistance, no consumables, and high efficiency, and has become the mainstream method for marking bundled boxes. Therefore, it is necessary to design a laser marking machine for bundled boxes.

[0003] The existing production process is quite complex. Bundling and coding are mostly done independently. After the products are bundled into a whole bundle by the bundling machine, the whole bundle needs to be manually moved to the laser coding machine station. After coding, it is then manually transferred to the collection drive. This operation method involves many manual interventions, resulting in high labor costs. During the transfer process, the whole bundle is prone to scattering or tilting, affecting the stability of subsequent coding and delaying the production rhythm. At the same time, the coding accuracy is poor and the labeling quality is unstable. When manually placing the whole bundle, it is difficult to ensure that the positioning is consistent each time. Problems such as coding position deviation and tilting often occur, resulting in QR codes that cannot be recognized and text that is incomplete. In addition, there is a lack of limit guide design. The whole bundle is prone to lateral or longitudinal displacement due to vibration and friction during the transmission process, which further aggravates the coding deviation. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed laser marking machine for whole bundles of boxes in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A laser marking machine for whole bundles includes a main body of the bundling machine. The output end of the main body of the bundling machine is equipped with a conveying component that works with it. A limiting and pushing component that works with it is fixedly installed on the top side of the conveying component near the main body of the bundling machine. The main body of the laser marking machine is placed on top of the conveying component on the back side away from the main body of the bundling machine.

[0007] As a further optimization of this utility model, the conveying assembly includes a fixed frame placed at the output end of the strapping machine body and below the bottom of the laser marking machine body. Both sides inside the fixed frame are rotatably mounted with transmission rollers. The two transmission rollers are fitted together with a transmission belt that cooperates with them. A discharge chute is fixedly installed on the side of the fixed frame away from the strapping machine body, which is located below the transmission belt and fixedly connected to the fixed frame.

[0008] As a further optimization of this utility model, side plates that are fixedly connected to the fixing frame are added to both ends of the top of the conveyor belt. A drive motor is fixedly installed on one side of the back of the fixing frame near the main body of the strapping machine, and the output end of the drive motor is fixedly connected to a conveyor roller.

[0009] As a further optimization of this utility model, the limiting and pushing assembly includes two guardrails fixedly installed on the two side plates, one end of which is close to the side of the strapping machine body, and a blocking rod is rotatably connected to the side of the two guardrails away from the strapping machine body.

[0010] As a further optimization of this utility model, the main body of the strapping machine includes a frame, a transmission mechanism, a feeding mechanism, a heat sealing mechanism, a core control unit, a photoelectric sensor, and a hydraulic system. The bottom of the frame is fixedly installed with a transmission mechanism that cooperates with the conveyor belt. One end of the transmission mechanism is fixedly installed with a feeding mechanism that is fixedly installed at the top of the frame. One end of the back of the feeding mechanism is fixedly installed with a heat sealing mechanism that is fixedly connected to the top of the frame and placed above the transmission mechanism. The core control unit, the photoelectric sensor, and the hydraulic system are fixedly installed on one side of the frame.

[0011] As a further optimization of this utility model, the main body of the laser marking machine includes an equipment mounting shell, a laser, a galvanometer scanning system, a control system, and a power supply system. The laser is placed on the side above the top of the conveyor belt away from the main body of the strapping machine. The equipment mounting shell is fixedly installed on the side of the laser away from the main body of the strapping machine. The galvanometer scanning system, the control system, and the power supply system that cooperate with the laser are fixedly installed inside the equipment mounting shell.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problems of printing three anti-counterfeiting product numbers on each box, temporary storage in separate boxes, and error correction in previous production processes. It reduces the process flow and improves production efficiency. When combined with the main body of the bundling machine, the transportation components and the main body of the laser marking machine, it can realize the full-process automation integration and reduce manual intervention.

[0014] 2. This utility model, through the structural design of the limiting and pushing component, can effectively solve the problem of the orientation of the printed surface after wrapping. It is simple and effective, enabling the laser marking machine to simultaneously perform marking functions on multiple medicine boxes, ensuring marking accuracy in the later stages, simplifying the production process, and improving production efficiency in the later stages.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 , Figure 2 As shown, the laser marking machine for bundled medicine boxes includes a main body 1 and a pre-bundling unit. The main body 1 is the initial processing unit of the equipment, including a frame, a transmission mechanism, a feeding mechanism, a heat sealing mechanism, a core control unit, photoelectric sensors, and a hydraulic system. The frame is a steel structure frame, serving as the mounting base for all components. A transmission mechanism (such as a belt conveyor assembly) is fixedly installed at the bottom inside the frame for transporting the bundled medicine boxes. A feeding mechanism (such as a pusher cylinder and hopper assembly) is fixedly installed at one end above the transmission mechanism for pushing individual small medicine boxes after they have been properly arranged. The material is fed to the conveying mechanism, forming a stack of boxes to be bundled. A heat sealing mechanism (including heating elements and pressing components) is fixedly installed on one end of the back of the feeding mechanism. The heat sealing mechanism is fixed by a bracket at the top of the frame and is positioned directly above the conveying mechanism. It is used to heat seal and fix the strapping of the stack of boxes. A core control unit, photoelectric sensors, and a hydraulic system are integrated on one side of the frame. The core control unit (including a PLC controller) is used to coordinate the actions of each mechanism. The photoelectric sensors detect the material position in real time and trigger the bundling action. The hydraulic system provides power to the heat sealing mechanism and the feeding mechanism to ensure stable bundling pressure.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a fixed frame 302 is installed at one end of the main body 1 of the bundling machine. The fixed frame 302 is a welded steel frame, horizontally placed at one end of the transmission structure of the main body 1 and connected to it. The fixed frame 302 is the mounting carrier of the transmission structure. Two transmission rollers 305 are rotatably installed on both sides of the inside of the fixed frame 302 through bearings. The two transmission rollers 305 are together fitted with the transmission belt 300. The surface of the transmission belt 300 is made of anti-slip rubber material to prevent slippage when conveying the bundled boxes. A discharge chute 303 is fixedly installed on the side of the fixed frame 302 away from the main body 1 of the bundling machine by bolts. The discharge chute 303 is inclined downward (inclination angle 30°) and placed below the transmission belt 300 to receive the bundled boxes after coding and guide them. The conveyor belt 300 is guided to the collection area. Side plates 301 (15-20cm high) are vertically fixed at both ends of the top of the conveyor belt 300. The side plates 301 are welded and fixed to the fixing frame 302 to limit the lateral displacement of the bundled boxes and prevent them from deviating from the track during the conveying process. The back of the fixing frame 302 is near the side of the main body 1 of the bundling machine, and a drive motor 304 is fixedly installed on it through a motor mount. The output end of the drive motor 304 is fixedly connected to the shaft of a transmission roller 305 through a coupling. During operation, the transmission roller 305 is driven to rotate, which drives the conveyor belt 300 to run in a cycle. Later, the bundled medicine boxes can be transferred to the top of the conveyor belt 300 for transfer work through the structural design of the internal transmission mechanism of the main body 1 of the bundling machine.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, guardrails 200 are fixedly installed on one side of the two side plates 301, which are close to each other. The two guardrails 200 are symmetrically fixed in front of the output end of the strapping machine body 1. The height of the guardrails 200 is adapted to the height of the bundled box, and is used to guide the bundled box to enter the conveyor belt 300 accurately. The side of the two guardrails 200 away from the strapping machine body 1 is rotatably connected to a blocking rod 201 (the length is adapted to the spacing between the side plates). The blocking rod 201 can push down the medicine box after it has been transported and strapped on the surface of the conveyor belt 300, so that the medicine box after strapping can be placed horizontally on top of the conveyor belt 300, which facilitates the coding operation of multiple medicine boxes at the same time later.

[0026] like Figure 1 , Figure 2As shown, the laser marking machine body 4 is installed at the marking station at the top end of the conveyor belt 300. It is used to print traceability codes, production dates, and other information on the surface of the bundled boxes. It includes an equipment mounting shell, a laser, a galvanometer scanning system, a control system, and a power supply system. The laser (such as a CO2 laser with a power of 30W) is fixedly installed on the side of the top of the conveyor belt 300 away from the main body 1 of the bundling machine via a bracket. The laser head is vertically downward and aligned with the surface of the conveyor belt 300. The marking area corresponds to the running trajectory of the conveyor belt 300. The equipment mounting shell (metal protective shell) is fixedly installed on the side of the laser away from the main body 1 of the bundling machine. The galvanometer scanning system, control system, and power supply system are fixedly installed inside the equipment mounting shell via a partition. The galvanometer scanning system (including X / Y axis galvanometer motors) receives signals from the control system and controls the laser beam to deflect rapidly to achieve accurate marking. The control system (including a touch screen and marking software) is used to set parameters such as marking content and speed. The power supply system provides stable power to the laser, galvanometer, etc.

[0027] It should be noted that, during use, the operator can directly move the device to the designated location and connect the power supply. Then, the individual medicine boxes are stacked by the feeding mechanism of the main body 1 of the bundling machine. The transmission mechanism transports the stack of boxes to the area below the heat-sealing mechanism. The hydraulic system drives the heat-sealing mechanism to press down, completing the heat-sealing fixation with the strapping tape, forming a bundle. The bundled boxes are then pushed onto the conveyor belt 300 of the conveyor assembly 3 by the transmission mechanism of the main body 1. The guardrail 200 guides and corrects the posture, and the blocking bar 201 can push over the vertically placed stack of medicine boxes, facilitating the subsequent individual coding of each box in the stack. In operation, the drive motor 304 drives the conveyor belt 300 to run. The medicine boxes stacked by the blocking rod 201 to form a horizontally placed box are transported to the laser of the laser marking machine body 4. After the photoelectric sensor detects the material, it triggers the laser to work. The galvanometer scanning system controls the laser beam to complete the marking on the surface of the whole box. The marked whole box continues to run with the conveyor belt 300 and finally falls into the unloading trough 303. It slides through the inclined trough to the collection area, completing one marking cycle. This embodiment realizes the fully automated operation of the whole box from bundling to marking through the precise cooperation of each component, which greatly improves the production efficiency and marking accuracy, and is suitable for large-scale batch production scenarios.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
