[0001] The utility model relates to the technical field of packaging marking, and particularly relates to an automatic filling laser coding and marking machine. Background Art

[0002] In the existing production process of goods packaging, there are significant problems with insufficient automation in traditional bagging operations. Operators need to participate in multiple process steps such as bag support and positioning, material filling, bag mouth sealing, and marking throughout the process. This labor-intensive operation mode leads to three technical defects: First, excessive manual intervention significantly reduces production efficiency and is difficult to meet the high-speed continuous operation requirements of modern production lines; Second, manual operation inevitably generates quality risks such as bagging positioning deviation, loose sealing, and marking misalignment; Finally, there is a lack of coordinated control mechanism between processes. For example, material discharging operations may be accidentally triggered when the packaging bag is not fully opened, resulting in material spillage. Existing equipment generally has the problem of fragmented functional modules. The filling mechanism, bag support device, and marking system often operate independently, lacking overall linkage control. This not only increases the complexity of the equipment but also causes time delays in process connection. Especially in scenarios with high-precision marking requirements, traditional mechanical marking mechanisms are difficult to achieve precise synchronization with the filling process, affecting the standardization and consistency of product markings.

[0003] In view of the above problems, there is an urgent need for improvement in the existing technology. Content of the Utility Model

Detailed Implementation

[0058] 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.

[0059] Example 1:

[0060] like Figures 1 to 6 As shown, this embodiment provides an automatic filling laser coding and marking machine, including a frame 1, a hopper 2 arranged on the frame 1, a feeding mechanism arranged at the discharge port of the hopper 2 for controlling the discharge, a bag-supporting mechanism arranged at the bottom of the hopper 2 for opening the packaging bag, an automatic receiving mechanism for placing the packaging bag, and a marking mechanism arranged on one side of the automatic receiving mechanism for marking the packaging bag.

[0061] The bag-supporting mechanism and the material-discharging mechanism are connected by a control mechanism. The material-discharging mechanism is controlled to discharge material only after the bag-supporting mechanism extends and supports the bag. The control mechanism is an interlocking control system built by sensors and controllers. Specifically, a pressure sensing device can be used to detect the extension state of the bag-supporting mechanism. When the bag is detected to be in place, a signal is sent to the controller, which then drives the material-discharging mechanism to open.

[0062] Specifically, the feeding mechanism includes a feeding plate 3 that is rotatably installed at the discharge port of the hopper 2 and a servo motor 4 that drives the feeding plate 3 to rotate. When the feeding plate 3 is in a horizontal position, it can completely block the discharge port.

[0063] When the discharge plate is in a horizontal position, it can completely block the discharge port.

[0064] The discharge plate is a flat plate component that controls the opening and closing of the hopper outlet through rotation. It can be made of sheet metal, and its rotating shaft is hinged to the edge of the hopper outlet. When in a horizontal position, it completely fits against the edge of the outlet to form a seal. This structure allows for adjustment of material flow rate by rotating the plate while achieving a reliable seal.

[0065] The servo motor refers to the power unit that drives the feeding plate to rotate. Specifically, it can be a servo motor with a reducer, and the rotation angle is precisely controlled through encoder feedback. The output shaft of the servo motor is rigidly connected to the rotating shaft of the feeding plate through a coupling to ensure stable torque transmission. This device uses closed-loop control to ensure that the material flow is completely blocked when the feeding plate is in a horizontal position.

[0066] Specifically, the feeding plate initially remains horizontal, closing the hopper outlet. When feeding is required, a servo motor drives the feeding plate to rotate downwards around its axis according to a control signal, allowing material to flow out of the outlet. The rotation angle of the feeding plate can be adjusted according to preset parameters; for example, rotating to 30 degrees creates a semi-open state to control the flow rate. After filling is complete, the servo motor rotates in the opposite direction, returning the feeding plate to its horizontal position. At this point, the edge of the feeding plate is in close contact with the inner wall of the outlet, effectively preventing material leakage. Through precise position control of the servo motor, this mechanism enables automated execution of the feeding action and flow rate regulation.

[0067] Through the above technical solution, this application achieves automated and precise control of material flow during the filling process, avoiding material leakage or overfilling caused by improper manual operation. The linkage design between the feeding plate and the servo motor allows the feeding action to be seamlessly integrated into the automated production process, significantly reducing the need for manual intervention while improving the consistency and stability of the filling process.

[0068] Example 2:

[0069] Based on Embodiment 1, in order to achieve no material leakage without opening the bag, the bag supporting mechanism includes a three-claw or four-claw structure supporting frame 5, a drive disk 6 arranged above the supporting frame 5, and a drive assembly arranged on the drive disk 6 for driving the drive disk 6 to rotate. The top of the supporting frame 5 is engaged with the bottom of the drive disk 6.

[0070] The identification mechanism includes a mounting groove 7 arranged on the support frame 5, a trigger rod 8 slidably arranged in the mounting groove 7, and an identification ring 9 arranged on the inner wall of the mounting groove 7 and movably connected to the trigger rod 8. A spring 701 is arranged in the mounting groove 7 and is sleeved on the trigger rod 8 to reset the trigger rod 8. The identification ring 9 is a pressure sensor that transmits pressure signals to the control mechanism and controls the feeding mechanism to feed the material.

[0071] After the packaging bag is placed into the automatic receiving mechanism by the robotic arm, the three- or four-claw structure of the bag-opening mechanism extends outward under the action of the drive component, fully opening the bag opening. Once the pressure sensor in the control mechanism detects that the claws are in position, the controller activates the discharging mechanism to open the hopper outlet. After the material is filled to the preset weight, the packaging machine immediately heat-seals the bag opening. The sealed packaging bag is then conveyed to the marking mechanism via a conveyor belt, where a laser marking machine adds the identification information. The entire process requires no manual intervention in the start / stop control of any step.

[0072] Compared with existing technologies, traditional packaging equipment requires manual confirmation of the bag opening status before manually opening the discharge valve. This solution achieves automated process connection through a linkage mechanism, eliminating the time delay and risk of misoperation caused by manual operation.

[0073] Through the above technical solution, this application realizes automated assembly line operation of bag opening, filling, sealing, and labeling processes, effectively solving the problems of low efficiency and high error rate of manual operation. The linkage mechanism ensures precise coordination between processes and avoids waste caused by material spillage.

[0074] Specifically, the control mechanism includes an identification mechanism arranged on the support frame 5 to identify whether the packaging bag has been opened, and a control mechanism for receiving signals from the identification mechanism and controlling the feeding mechanism to feed the material. The control mechanism is a programmable logic controller.

[0075] The identification mechanism refers to the sensing device used to detect the working status of the bag-opening mechanism. Specifically, it can be implemented using a combination of a trigger rod and a pressure sensor. The trigger rod is compressed when the bag-opening mechanism is not deployed; when the bag-opening mechanism is fully deployed, the trigger rod is released, making it contact the pressure sensor. The control mechanism refers to the computing unit that coordinates the equipment's actions. Specifically, it can be implemented using a programmable logic controller (PLC). It receives electrical signals from the pressure sensor and converts them into control commands, thereby driving the servo motor to execute the material feeding action.

[0076] Specifically, when the bag-opening mechanism extends to the set position, the trigger rod slides along the mounting groove due to the displacement of the opening frame. At this time, the spring is compressed, causing the trigger rod to contact the recognition ring. The pressure sensor converts the contact signal into an electrical signal and transmits it to the programmable logic controller (PLC). After the preset program determines that the bag-opening action is complete, the controller sends a command to the servo motor to open the feeding plate. This achieves the timing linkage between the bag-opening action and the feeding action, preventing material spillage caused by premature feeding before the packaging bag is fully open.

[0077] Compared to existing technologies, traditional equipment relies on manual visual judgment of the bag-filling completion status before discharging material, which carries the risk of misjudgment and has limited response speed. This solution, through the coordinated detection of mechanical triggering and electronic sensing, can accurately capture the physical displacement of the bag-filling mechanism. Combined with the real-time signal processing of the programmable controller, it can ensure that the material discharging action is automatically triggered only after the bag is in place.

[0078] Through the above technical solution, this application can effectively eliminate the problem of process disconnect caused by manual operation. Through the coordinated cooperation of mechanical structure and control system, the seamless connection between bag opening and material feeding process can be achieved, avoiding material waste caused by operation delay or misjudgment, while reducing the frequency of manual intervention and thus improving the efficiency of production line operation.

[0079] This application further proposes an identification mechanism including a mounting slot arranged on a support frame, a trigger rod slidably arranged in the mounting slot, an identification ring arranged on the inner wall of the mounting slot and movably connected to the trigger rod, a spring arranged in the mounting slot and sleeved on the trigger rod for resetting the trigger rod, and the identification ring being a pressure sensor that transmits pressure signals to the control mechanism and controls the feeding mechanism to feed material.

[0080] The mounting groove refers to the fixed structure set on the support frame, which can be implemented using a machined groove structure to limit the movement trajectory of the trigger rod. The trigger rod is a detection element that can slide along the axial direction of the mounting groove, and can be implemented using a stainless steel cylindrical rod; its end generates displacement when it contacts the inner wall of the packaging bag. The identification ring is a sensing element used to detect changes in the position of the trigger rod, and can be implemented using a piezoelectric ceramic ring sensor; it generates a change in electrical signal when the trigger rod slides under pressure. The spring is an elastic element that provides the restoring force, and can be implemented using a helical compression spring; its preload adjusts the initial position of the trigger rod.

[0081] Specifically, when the support frame extends outward, the inner wall of the packaging bag presses against the end of the trigger rod. The trigger rod slides inward along the mounting groove and compresses the spring. The displacement of the trigger rod causes radial pressure on the identification ring, and the pressure sensor converts the mechanical signal into an electrical signal, which is transmitted to the control mechanism. After receiving a valid pressure signal, the control mechanism determines that the bag-opening action is complete and then starts the discharging mechanism to perform the discharging operation. After the packaging bag is detached, the spring pushes the trigger rod back to its initial extended state, ready for the next work cycle.

[0082] Compared to existing technologies, traditional equipment requires manual judgment of the bag-supporting status before manually initiating material discharge, which poses operational delays and risks of misoperation. This solution achieves automatic detection of the action status through the mechanical linkage of a trigger rod and a pressure sensor, forming a reliable interlocking control logic to ensure that the material discharge action is triggered only when the bag is in position.

[0083] Through the above technical solution, this application realizes automatic interlock control of bag opening state and material dispensing action, eliminates the operational error of manual judgment, ensures the accuracy of the action sequence of bag opening mechanism and material dispensing mechanism during bagging process, effectively prevents material spillage caused by accidental material dispensing when the bag is not open, and improves the reliability of automated bagging process.

[0084] The drive assembly includes a drive gear 10 and a servo motor 11 that drives the drive gear 10 to rotate. The drive gear 10 is meshed with the top of the drive disk 6, and the meshing connection between the drive gear 10 and the drive disk 6 is a helical gear meshing connection.

[0085] When the drive assembly starts, the servo motor drives the drive gear to rotate. The helical gear meshing structure between the drive gear and the drive disk converts the rotational motion into the axial rotation of the drive disk. The toothed structure at the bottom of the drive disk meshes with the rack at the top of the expansion frame, converting the rotational motion of the drive disk into the radial synchronous displacement of the expansion frame. During the displacement, the three- or four-jaw expansion frame expands outward, evenly opening the packaging bag opening to the predetermined size, at which point the subsequent feeding action is triggered. The helical gear meshing structure can disperse contact stress during movement, avoiding asynchronous displacement of the expansion frame caused by tooth surface wear.

[0086] Compared to existing technologies, traditional bag-opening mechanisms often employ single-point drive or pneumatic pusher structures, resulting in uneven bag-opening force and asynchronous claw movements, leading to bag deformation or material leakage. This solution utilizes a drive disc connected to the helical gears of the opening frame, enabling multiple claws to achieve precise synchronous displacement under a single power source. Simultaneously, the helical gear structure improves transmission stability, resolving the inefficiency caused by manual adjustment of the bag-opening angle.

[0087] Example 3:

[0088] Based on Embodiment 2, this application further proposes an automatic receiving mechanism including a tray 12, a weighing base 13 arranged on the tray 12, and a packing machine 14 arranged directly above the tray 12 for sealing packages;

[0089] One side of the pallet 12 is equipped with a robotic arm 15 for transfer, and the weighing base 13 is electrically connected to the control mechanism. The weighing base 13 sends the weighing signal to the control mechanism to control the material feeding mechanism to feed the material.

[0090] The pallet is a support platform used to hold the packaging bags. It can be made of welded metal sheets, and its surface can be textured with anti-slip patterns to enhance the stability of the packaging bags. The weighing base is a weight detection device integrated inside the pallet, which can be implemented using strain gauge sensors. It generates electrical signals by monitoring changes in the weight of the packaging bags in real time. The packing machine is a device used to seal the bag openings, which can be implemented using a heat-sealing mechanism. Its heating temperature range can be controlled between 120-180℃ to accommodate packaging bags of different materials. The robotic arm is a material transfer device, which can be implemented using a multi-joint servo-driven robotic arm. The end effector can be equipped with a vacuum suction cup or gripper to accommodate packaging bags of different sizes.

[0091] Specifically, after the packaging bag is unfolded by the bag-opening mechanism, the pallet receives and carries the bag, while the weighing base continuously monitors changes in the bag's weight. When the weight reaches a preset threshold, the control mechanism immediately cuts off the feeding action of the feeding mechanism, and then the packaging machine heat-seals the bag opening. After sealing, the robotic arm picks up the packaging bag and transfers it to the conveyor belt for subsequent marking operations. The entire process is precisely controlled through weight feedback, preventing material spillage or underfilling.

[0092] Compared to existing technologies, traditional packaging operations require manual operation of weighing instruments and manual opening and closing of material discharge valves, resulting in response lag and operational errors. This solution integrates weighing sensors with an automatic control loop to achieve real-time acquisition and feedback adjustment of weight data. Simultaneously, a robotic arm automatically transfers finished products, effectively eliminating manual operation.

[0093] Through the above technical solution, this application realizes closed-loop control of the filling weight of packaging bags, ensuring that the filling accuracy of each bag of material is controlled within the allowable error range. At the same time, the automated transfer process shortens the single operation cycle and reduces the downtime caused by manual intervention.

[0094] Preferably, an unloading mechanism, which is a conveyor belt, is arranged on one side of the automatic receiving mechanism.

[0095] Preferably, the marking mechanism includes a marking frame 16 arranged on one side of the conveyor belt 18 and a laser marking machine 17 arranged on the marking frame 16 with its laser emitter aligned with the conveyor belt 18.

[0096] The laser marking machine 17 is slidably arranged on the marking frame 16. A laser marking machine is a device that uses a laser beam for marking; specifically, it can be implemented using an ultraviolet laser generator in conjunction with a galvanometer system. For example, the wavelength parameter can be selected in the 355nm band. This application enables automatic product marking during the packaging process without manual intervention. The sliding adjustment structure allows the laser marking machine to adapt to the marking needs of packaging bags of different sizes, effectively avoiding the marking position offset problem caused by fixed installation of traditional equipment, and improving the continuous operation capability and marking accuracy of the production line.

[0097] After the automatic receiving mechanism completes the bagging, the packaging bags are transferred to the marking station via a conveyor belt. The UV laser marking machine, mounted on the marking frame, adjusts its position via a sliding mechanism to precisely align the laser emitter with the preset marking area on the packaging bag. Once the packaging bag is detected in place, the control system initiates the laser marking program, using UV laser light to instantly vaporize and form a permanent mark with controllable depth on the bag's surface. Because it uses a 355nm wavelength UV laser, it can produce clear marks with a contrast of over 70% on the surface of conventional packaging materials such as polypropylene and polyethylene, and the mark line width can be controlled within an accuracy range of 0.1mm.
