Description

Technical Field

[0001] This invention relates to the field of inkjet printing, and in particular to a laser inkjet printer for packaging finished hair conditioner products. Background Technology

[0002] In the production process of daily chemical products, such as viscous liquid products like hair conditioner, after filling and packaging, it is usually necessary to use a laser marking machine to mark the production date, batch number, or traceability information on the bottle surface to meet the requirements of product quality management and market circulation.

[0003] Existing laser marking equipment typically includes a conveyor and a marking device. Bottles are transported to the marking station via a conveyor belt, where a printhead marks the bottle surface. However, in the packaging of viscous liquid products such as hair conditioner, due to the product's adhesive properties, liquid residue can easily remain on the bottle neck or body after filling or sealing. Furthermore, this residue can generate volatile substances or tiny droplets in the production environment, leading to contamination issues in the marking area.

[0004] The aforementioned contaminants may adhere to the coding area on the bottle, affecting the clarity and adhesion of the laser coding; they may also adhere to the surface of the coding pad or its optical components, causing unstable laser output and thus affecting coding quality. Furthermore, most existing coding equipment uses an open structure, with the coding area directly exposed to the external environment, lacking effective local protection measures. This makes it easier for external airflow disturbances and contaminants to enter the coding area, further reducing coding stability.

[0005] To address the aforementioned issues, existing technologies include solutions that improve the coding environment by incorporating airflow protection structures or exhaust devices. For example, air curtains can be used to block outside air from entering, or exhaust devices can remove contaminated gases. However, single airflow structures still have shortcomings in practical applications: airflow is prone to turbulence, interfering with the laser coding path and consequently affecting coding accuracy; furthermore, these structures are often not designed holistically to integrate the transport process and coding technology, making it difficult to maintain a stable environment in the coding area under dynamic production conditions. Summary of the Invention

[0006] One object of the present invention is to provide a laser marking machine for packaging and processing finished hair conditioner products that at least solves any of the above-mentioned technical problems.

[0007] Specifically, the present invention provides a laser marking machine for the packaging processing of finished hair conditioner products, comprising, Conveyor racks are used to transport finished packaged bottles; The coding protection mechanism is located on the upper part of the conveyor frame and includes a protective channel, a protective cover, and an exhaust duct. The protective channel is located above the conveyor frame, with both ends extending through to form a channel for the bottle to pass through; The protective cover is disposed in the middle of the protective channel and is at least partially located within the protective channel, and a coding area is formed inside the protective cover; The exhaust duct is located on at least one side of the protective channel and has an exhaust port located below the coding area.

[0008] Furthermore, the coding protection mechanism also includes an air curtain mechanism, which is disposed on the upper part of the protective cover and forms an air curtain above the coding area.

[0009] Furthermore, a first sealing element and a second sealing element are respectively provided at the two ends of the protective channel to form a dynamic seal when the bottle passes through.

[0010] Furthermore, the lower part of the air curtain mechanism is provided with a guide plate to control the airflow direction and make the airflow form laminar flow.

[0011] Furthermore, the protective cover includes an air curtain mechanism, a coding area, and a ventilation area arranged sequentially from top to bottom. The coding area of ​​the protective cover has a movable slot on one side, and a spray nozzle that moves along the movable slot is arranged inside the movable slot.

[0012] Furthermore, the exhaust duct includes a flat duct and an external duct, the flat duct and the external duct are connected, and the flat duct is located between the placement plate and the conveying plate, and an exhaust port is provided on the upper part of the flat duct.

[0013] Furthermore, the exhaust vent portion is located relative to the lower part of the placement plate.

[0014] Furthermore, the protective cover has a trumpet-shaped cross-section.

[0015] A laser marking machine for packaging finished hair conditioner products, comprising: Conveyor rack; A fixing mechanism, installed on the conveyor frame, is used to clamp finished product packaging bottles; The fixing mechanism includes a fixed base, a fixed cylinder, a movable block, a spring, a placement plate, a crank leg, and a clamp. The movable block is slidably disposed inside the fixed cylinder, the placement plate is fixed to the upper end of the movable block, and the spring is disposed at the lower end of the movable block; The shank is located on the edge of the placement tray, the clamp is located at the upper end of the shank, and a roller is located at the lower end of the shank.

[0016] The technical effects and advantages of this invention are as follows: This invention utilizes an air curtain and negative pressure ventilation to create directional airflow, effectively isolating and removing contaminants and improving the cleanliness of the coding area. A guide plate reduces airflow turbulence, preventing interference with laser coding. By setting up a coding cover and channel structure, partial sealing is achieved while ensuring continuous bottle transport. In the fixing mechanism, the finished packaging bottle on one of the placement trays is located directly below the air curtain mechanism, and the bottles on the two adjacent placement trays form a semi-sealed state with both ends of the protective channel, further ensuring the local sealing effect of the bottle.

[0017] Meanwhile, in this invention, the fixing mechanism can effectively and stably clamp the bottle. In use, the bottle is placed on the placement plate along the radial direction of the clamps. The weight of the bottle filled with material causes the placement plate to sink, facilitating the fixation of the bottle. When the bottle is placed on the placement plate, the movable block moves downward against the elastic force of the spring, the roller contacts the external guide surface and drives the crank leg to rotate, causing the clamps to close and clamp the bottle. At the same time, when the placement plate moves directly below the air curtain mechanism, after the air curtain and the exhaust pipe are activated, since the exhaust port of the flat pipe is located below the placement plate, a downward pressure can be formed on the placement plate during the inkjet printing process, making the inkjet printing on the bottle more stable.

[0030] In this embodiment, the present invention provides a laser marking machine for the packaging and processing of hair conditioner products. It is mainly used for high-quality laser marking of production date, batch number or traceability code on the surface of bottle 8 after filling and sealing of viscous liquid products such as hair conditioner. Specifically, it includes a conveyor frame 1, a fixing mechanism 3 and a marking protection mechanism. The three work together to ensure conveying efficiency while effectively improving the cleanliness of the marking environment and the stability of the marking process.

[0031] The conveyor frame 1 serves as the basic support structure of the entire machine, employing a rigid metal frame. A conveyor plate 101 is horizontally mounted on its upper part to support the fixing mechanism 3 and guide its movement along a predetermined direction. Track plates 2 are symmetrically arranged on both sides of the conveyor plate 101 along its length, forming a guide slide structure with the conveyor plate 101 to ensure that the fixing mechanism 3 remains stable and aligned during movement, preventing deviation. A drive device, such as a sprocket and chain mechanism driven by a stepper motor or servo motor, can be installed below the conveyor plate 101 to achieve intermittent or continuous conveying of the fixing mechanism 3, facilitating linkage with upstream and downstream filling, sealing, and packaging equipment. The fixing mechanism 3 is used to position and clamp the finished bottle 8 during the conveying process to ensure that it does not shake or tip over during the coding process. The fixing mechanisms 3 are evenly spaced on the conveyor frame 1. The distance between two adjacent fixing mechanisms 3 is reasonably set according to the diameter of the bottle 8 and the length of the coding station to ensure the continuity and consistency of the coding operation.

[0032] Specifically, such as Figures 2 to 6 As shown, the fixing mechanism 3 includes a fixing base 9, a fixing cylinder 307, a movable block 306, a spring 305, a placement tray 303, a crank leg 302, and a clamp 301. The fixing base 9 is fixedly installed on the upper surface of the conveyor plate 101, and its structure is stable and reliable, serving as the mounting base for the entire fixing mechanism 3. The fixing cylinder 307 is a hollow cylindrical shape, vertically fixed to the upper part of the fixing base 9, and its interior forms a guide cavity. The movable block 306 is slidably fitted inside the fixing cylinder 307 and can move up and down along its axial direction. The upper end of the movable block 306 extends out of the fixing cylinder 307 and is fixedly connected to the placement tray 303, which is used to support the bottom of the finished bottle 8. A spring 305 is provided between the lower end of the movable block 306 and the bottom of the fixing cylinder 307. The spring 305 is always in a compressed state, providing an upward preload force for the movable block 306.

[0033] The placement tray 303 has symmetrically arranged mounting slots along its left and right edges, and each mounting slot contains a shank 302. The shank 302 has an L-shaped or arc-shaped structure, and a clamp 301 is mounted on its upper part by a hinge or elastic connection. The inner surface of the clamp 301 can be made of flexible material to increase the friction with the bottle 8 while avoiding scratching the surface of the bottle 8. A roller 304 is provided at the lower end of the shank 302, and the roller 304 rolls in contact with a specific guide surface on the track plate 2 or the conveyor plate 101.

[0034] The working process of the fixing mechanism 3 is as follows: When the bottle 8 is not placed, the movable block 306 is in the upper position under the elastic force of the spring 305. At this time, the roller 304 at the lower end of the crank leg 302 is not subjected to external force, and the clamp 301 is in the open state; when the finished bottle 8 is placed on the placement tray 303 along the radial direction of the clamp 301, the weight of the bottle 8 or the weight after being filled with liquid overcomes the elastic force of the spring 305, causing the movable block 306 to move downward; the movable block 306 moves downward... During the process, the placement tray 303 moves downwards synchronously, and the crank leg 302 sinks accordingly. The roller 304 at its lower end contacts the inclined surface or guide groove on the track plate 2 and generates relative rolling, forcing the crank leg 302 to rotate around its central fulcrum. This causes the upper clamping claw 301 to close towards the center of the bottle body 8, achieving automatic clamping of the bottle body circumferentially. When the bottle body 8 is removed, the spring 305 pushes the movable block 306 to reset, and the clamping claw 301 automatically opens, facilitating the placement of the next bottle body 8. This structure requires no additional power and relies on the weight of the bottle body 8 to complete the clamping. It has a compact structure, is highly responsive, and is especially suitable for high-speed continuous production lines. The inkjet printing protection mechanism is located on the upper part of the conveyor frame 1 at the inkjet printing station. It is used to create a locally enclosed and clean environment during the inkjet printing process to prevent contaminants from interfering with the laser inkjet printing effect. It mainly consists of three parts: a protective channel 4, a protective cover 5, and an exhaust pipe 6. The protective cover has a trumpet-shaped cross-section.

[0035] like Figure 1 , Figure 3 , Figure 5 , Figure 8 As shown, the protective channel 4 is a hollow shell structure, located above the conveyor plate 101, with its two sides fixedly connected to the upper part of the track plate 2 to ensure parallel alignment with the conveying direction; the two ends of the protective channel 4 are arranged through the conveying direction to form an inlet and an outlet for the bottle 8 to pass through. The internal space width of the protective channel 4 is slightly larger than the maximum diameter of the bottle 8 to allow the bottle 8 to pass through smoothly, while minimizing the entry of external airflow.

[0036] To further improve the sealing effect, such as Figure 3As shown, a first sealing element 401 and a second sealing element 402 are respectively provided at the openings at both ends of the housing 403 of the protective channel 4. The first sealing element 401 and the second sealing element 402 are symmetrically arranged on the left and right. The sealing elements can be made of flexible materials, such as rubber or silicone. When the bottle 8 passes through, it forms a dynamic seal with the edge of the bottle or the placement tray 303, effectively blocking external airflow and pollutants from entering the interior of the protective channel 4.

[0037] The protective cover 5 is located in the middle of the protective channel 4, partially inside the protective channel 4, forming a working area for the coding operation; such as Figure 7 As shown, the protective cover 5 includes an air curtain mechanism 501, a coding area 502, and a ventilation area 503 arranged sequentially from top to bottom. The air curtain mechanism 501 is located at the upper part of the protective cover 5 and has an airflow distribution cavity inside. It is supplied with air by an external air source and can form a uniform air curtain from top to bottom above the coding area 502. This air curtain can effectively block outside air, dust, and volatiles from entering the coding area 502. A movable slot 504 is provided on one side of the protective cover 5. The movable slot 504 is a long slot extending in the vertical direction. The inkjet terminal 7 is installed in the movable slot 504 and can move up and down or lock along the slot to adapt to the coding position requirements of bottles 8 of different heights. The inkjet terminal 7 is connected to an external laser generator and is used to emit a laser beam to form a mark on the surface of the bottle 8.

[0038] The exhaust duct 6 is used to promptly remove volatiles, tiny droplets, and particulate matter generated during the coding process, preventing them from depositing on the optical lens of the inkjet nozzle 7 or the surface of the bottle 8; for example Figure 7 , Figure 8 , Figure 9 As shown, the exhaust duct 6 includes a flat duct 601 and an external duct 603, which are interconnected. The flat duct 601 is located in the gap between the placement tray 303 and the conveyor plate 101, and multiple exhaust ports 602 are spaced apart along its length on its upper part. In a preferred embodiment, the exhaust ports 602 are located below the placement tray 303. When the exhaust system is started, the exhaust ports 602 can not only remove contaminants from the lower part of the coding area 502, but also generate a downward suction force on the placement tray 303, further increasing the stability of the placement tray 303 and preventing the bottle 8 from moving slightly due to external vibration or airflow disturbance during the coding process, thereby ensuring coding accuracy.

[0039] To further improve the stability of the air curtain, such as Figure 7As shown, a guide plate 10 is provided at the lower part of the air curtain mechanism 501. The guide plate 10 adopts a perforated plate or grid structure to rectify the airflow output by the air curtain mechanism 501, so that it forms a uniform laminar flow rather than a turbulent flow, avoiding interference of high-speed airflow with the laser beam, thereby ensuring that the inkjet pattern is clear and the edges are sharp.

[0040] During operation, when the fixing mechanism 3 carries the finished bottle 8 into the protective channel 4, it passes through the first sealing member 401 and enters the coding area 502 directly below the protective cover 5. At this time, the bottle 8 is located directly below the air curtain mechanism 501, and the bottles 8 on the two adjacent fixing mechanisms 3 are close to the entrance and exit of the protective channel 4, respectively, forming a semi-sealed state with the first sealing member 401 and the second sealing member 402. This segmented sealing structure ensures continuous conveying of the bottle 8 while effectively reducing the gas exchange channel between the external environment and the coding area 502, greatly reducing the possibility of contaminant intrusion.

[0041] The working process of the equipment of the present invention is as follows: First, the filled and sealed conditioner bottles 8 are placed sequentially on the placement tray 303 of the fixing mechanism 3. The weight of the bottles 8 causes the clamps 301 to automatically clamp the bottles 8. The conveyor frame 1 drives the fixing mechanism 3 to move along the conveyor plate 101, and the bottles 8 enter the protective channel 4 sequentially. When the bottles 8 reach the coding area 502, the air curtain mechanism 501 is activated to form an air curtain from top to bottom. The exhaust pipe 6 is activated simultaneously, drawing air downward through the exhaust port 602 to form a negative pressure area, which promptly discharges the volatiles, micro-droplets and dust generated during the coding process. The spray nozzle 7 emits a laser beam according to a preset program to form a clear and firm mark on the surface of the bottle 8 or the cap. After coding is completed, the bottles 8 continue to move with the conveyor plate 101, leave the protective channel 4 through the second sealing element 402, and enter the next process.

[0042] Working principle of this invention: In use, the coordinated action of the air curtain mechanism 501 and the exhaust pipe 6 forms a directional airflow circulation in the coding area 502. The air curtain isolates external pollutants, and the exhaust pipe promptly removes internal pollutants, effectively improving the cleanliness of the coding area and preventing blurring or detachment of the coding due to pollutant adhesion. The protective channel 4 is equipped with the first sealing element 401 and the second sealing element 402 at both ends. Combined with the positional relationship of adjacent bottles, it achieves partial sealing under continuous conveying conditions. The structure is simple and has a good sealing effect. The overall structure can clamp the bottle without additional power, and the coding process is completed automatically. It is suitable for high-speed continuous production, reduces manual intervention, and improves production efficiency.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
