Description

Technical Field

[0001] The utility model relates to the technical field of laser coding on cosmetic packaging, in particular to a laser coding integrated device. Background Art

[0002] What is sprayed is a permanent mark that cannot be erased. It is vaporized instantly on the surface of the object by laser. It can be distinguished by the naked eye without the help of any auxiliary tools, making it easy for consumers to identify.

[0003] UV laser inkjet printers use a nanosecond solid-state UV laser as their laser source and employ a water-cooled circulation system for precise temperature control. They offer high beam quality and power stability, making them suitable for marking product packaging or surfaces on plastics, paper, glass, ceramics, metals, and more. With high energy density and a minimal heat-affected zone, they are particularly suitable for marking detailed materials requiring high quality.

[0004] Chinese patent publication number CN221067527U discloses an adjustable UV laser inkjet printer, comprising: a base plate, a main chassis, a lifting frame, a mobile frame, a rotating plate, a mounting plate, a universal adjustment assembly, and a laser inkjet printer body. The main chassis is mounted on the base plate; the lifting frame is disposed on the base plate; the mobile frame is connected to the lifting frame; the rotating plate is mounted on the mobile frame; the mounting plate is connected to the rotating plate; the universal adjustment assembly is mounted on the mounting plate; and the laser inkjet printer body is connected to the universal adjustment assembly. The utility model utilizes a rotating sphere that can rotate within a socket, allowing the rotating sphere to universally rotate on the base. The laser inkjet printer body can then rotate under the action of a support column and a connecting rod, enabling the printer to print at different angles and for products with different patterns, effectively improving the printer's operational versatility.

[0005] Regarding the above-mentioned related technologies, in the existing technology, workers use the main body of the laser inkjet printer to mark products. The laser inkjet printer will generate exhaust gas during operation. However, the laser inkjet printer in the existing technology is not equipped with relevant means to treat the exhaust gas. The exhaust gas will pollute the environment and affect the health of the workers, reducing the applicability of the ultraviolet laser inkjet printer. Utility Model Content

[0006] In order to improve the applicability of laser coding integrated equipment, the present application provides a laser coding integrated equipment.

[0007] This application provides a laser coding integrated device using the following technical solutions:

[0008] A laser coding integrated device includes a frame, on which a conveyor belt, a smoke purifier, a laser coding machine and a controller are provided. The smoke purifier and the laser coding machine are electrically connected to the controller. A protective cover is installed on the frame, the protective cover is located above the conveyor belt, and the protective cover is provided with an avoidance gap to accommodate the passage of products.

The marking end of the laser coding machine is located in the protective cover and faces the conveyor belt.

[0009] By adopting this technical solution, during marking, workers place the product on a conveyor belt, which transports it into a protective cover. A controller then activates the laser printer to mark the surface of the product packaging. Simultaneously, a smoke purifier is activated to absorb exhaust gas from the protective cover, achieving surface marking. The protective cover limits the spread of exhaust gas, while the smoke purifier absorbs and filters it, reducing the potential for environmental pollution while protecting worker health. Compared to existing technologies, this improves the applicability of integrated laser marking equipment.

[0010] Optionally, guide guardrails are placed on both sides of the frame at positions corresponding to the conveyor belt inlet, and the guide guardrails include a guide part and a straight part, and the guide part and the straight part are integrally formed. The straight part is located between the guide part and the protective cover, and the guide part is arranged at an angle, with the reference direction from the conveyor belt inlet to the straight part. The distance between the two guide guardrails gradually shortens, and the frame is provided with an adjustment component for adjusting the position of the guide guardrail.

[0011] By adopting the above technical solution, when conveying products, the staff will use the adjustment component to adjust the distance between the two guide guardrails in advance according to the product size. When the product moves, the guided part automatically adjusts its position, and then the product angle is adjusted through the straight part to facilitate subsequent marking work, thereby improving the marking accuracy of the laser coding integrated equipment.

[0013] By adopting the above technical solution, when adjusting the guide guardrail, the staff rotates the rotating ring, and through the restriction of the restriction block and the thread cooperation of the rotating ring, the connecting rod moves, driving the guide guardrail to move, thereby achieving the effect of adjusting the distance between the two guide guardrails.

[0014] Optionally, a fixed block is connected to the frame, a guide rod is connected to the guide guardrail, and the guide rod is slidably fitted on the fixed block.

[0015] By adopting the above technical solution, the staff can make the installation and movement of the guide guardrail more stable through the cooperation of the guide rod and the fixed block.

[0016] Optionally, scale lines are provided on the guide rod.

[0017] By adopting the above technical solution, the scale lines are used to digitize the moving distance of the guide guardrail, so that the moving distance of the guide guardrail can be observed more conveniently and clearly, providing convenience for adjusting the position of the guide guardrail.

[0019] By adopting the above technical solution, when adjusting the position of the guide guardrail, the staff rotates the bidirectional screw, and through the restriction of the restriction rod and the thread cooperation of the bidirectional screw, the two moving seats move synchronously relative to each other, and the guide guardrail is driven to move through the connecting block, thereby achieving the effect of synchronously adjusting the distance between the two guide guardrails.

[0020] Optionally, an extension rod is connected to the guide guardrail, a placement groove is opened on the connecting block, a spring clip is placed in the placement groove, the extension rod passes through the connecting block and the spring clip, and a locking sleeve is threaded on the connecting block, and the locking sleeve presses against the spring clip.

[0021] By adopting the above technical solution, when installing the guide guardrail, the staff passes the extension rod through the connecting block and the spring clip, and then rotates the locking sleeve to cause the spring clip to deform under force and apply pressure to the extension rod, thereby limiting the movement of the extension rod and achieving the effect of installing the guide guardrail.

[0022] Optionally, a water cooler is installed on the rack, and the water cooler is electrically connected to the controller.

[0023] By adopting this technical solution, when marking products in batches, laser inkjet printers generate a lot of heat over long periods of time. Without cooling measures, the laser printers could be damaged by overheating. By using a water cooler to cool the laser printers, the staff ensured that the laser printers could operate for extended periods without damage.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. During marking, workers place products on a conveyor belt, which transports them into a protective cover. The controller then activates the laser printer to mark the surface of the product packaging. Simultaneously, the smoke purifier is activated to absorb exhaust gas from the protective cover, achieving surface marking. The protective cover limits the spread of exhaust gas, while the smoke purifier absorbs and filters it, minimizing the potential for environmental pollution while protecting worker health. This improves the applicability of integrated laser marking equipment compared to existing technologies.

[0026] 2. When adjusting the guide guardrail, the staff rotates the rotating ring. Through the restriction of the limiting block and the thread cooperation of the rotating ring, the connecting rod moves, driving the guide guardrail to move, achieving the effect of adjusting the distance between the two guide guardrails;

[0034] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0035] Example 1 of the present application discloses a laser coding integrated device. Figure 1 and Figure 2 The laser coding integrated equipment includes a frame 1, on which a conveyor belt 11, a smoke purifier 12, a laser coding machine 13 and a controller 14 are installed. The smoke purifier 12 and the laser coding machine 13 are electrically connected to the controller 14. A protective cover 2 is fixedly connected to the frame 1, and the protective cover 2 is located above the conveyor belt 11. A smoking hole is opened at the top of the protective cover 2, and an inspection door 21 is provided on one side wall of the protective cover 2. An avoidance gap 22 for avoiding the passage of products is provided at the bottom of the protective cover 2. An exhaust pipe is installed between the exhaust end of the smoke purifier 12 and the smoking hole. The exhaust pipe is a corrugated pipe. The marking end of the laser coding machine 13 is located in the protective cover 2 and faces the conveyor belt 11.

[0036] During marking, the staff places the product on the conveyor belt 11. When the product moves into the protective cover 2, the laser inkjet printer 13 is started to mark the surface of the product. At the same time, the smoke purifier 12 is started to extract the exhaust gas in the protective cover 2, thereby achieving the effect of marking the product surface.

[0037] Reference Figure 1 In order to ensure that the laser inkjet printer 13 can work normally for a long time, a water cooler 3 is installed on the frame 1. The water cooler 3 is electrically connected to the controller 14 and is used to cool the laser inkjet printer 13.

[0038] Reference Figure 2 A guide guardrail 4 is provided on both sides of the frame 1 at positions corresponding to the feed port of the conveyor belt 11. The guide guardrail 4 includes a guide portion 41 and a straight portion 42. The guide portion 41 and the straight portion 42 are integrally formed, and the straight portion 42 is located between the guide portion 41 and the protective cover 2. The guide portion 41 is arranged at an angle, and the distance between the two guide guardrails 4 gradually decreases from the feed port of the conveyor belt 11 to the straight portion 42 as a reference direction.

[0039] Reference Figure 2 and Figure 3 The frame 1 is provided with an adjustment assembly 5, which includes a rotating ring 51, a connecting rod 52, a limiting block 53, and a fixed seat 54. The connecting rod 52 is horizontally fixedly connected to the guide guardrail 4, and the fixed seat 54 is fixedly connected to the frame 1. The connecting rod 52 passes through the fixed seat 54. The limiting block 53 is fixedly connected to the fixed seat 54. The connecting rod 52 has a limiting groove 521 at the position corresponding to the limiting block 53, and the limiting block 53 slides in the limiting groove 521. The rotating ring 51 is rotatably connected to the fixed seat 54 and is threadedly engaged with the connecting rod 52.

[0040] When adjusting the position of the guide guardrail 4 , the staff rotates the rotating ring 51 , and the connection rod 52 is moved by the restriction of the limiting block 53 and the rotating ring 51 , thereby achieving the effect of adjusting the distance between the two guide guardrails 4 .

[0041] Reference Figure 3 To improve the stability of the guide guardrail 4, a guide rod 43 is fixedly connected to the guide guardrail 4. A fixed block is fixedly connected to the frame 1, and the guide rod 43 slides on the fixed block. The guide rod 43 is provided with scale lines 431 along its length. The scale lines 431 are used to quantify the movement distance of the guide guardrail 4, providing convenient adjustment for the guide guardrail 4.

[0042] The implementation principle of a laser coding integrated device in Example 1 of the present application is: when marking, the staff knows the size of the product in advance, rotates the rotating ring 51 to move the connecting rod 52, and adjusts the movement amount of the guide guardrail 4 according to the scale line 431 to limit the distance between the two straight parts 42 of the guide guardrail 4, and then places the product on the conveyor belt 11. When the product moves, it automatically adjusts the position of the product on the conveyor belt 11 according to the guide part 41, and then adjusts the angle through the straight part 42. When the product moves into the protective cover 2 and is located directly below the marking end of the laser coding machine 13, the laser coding machine 13 is started to mark the product, and the smoke purifier 12 is started at the same time to extract and filter the exhaust gas of the protective cover 2, thereby completing the marking of the product.

[0043] The staff uses the protective cover 2 to limit the diffusion of the exhaust gas, and uses the smoke purifier 12 to absorb and filter the exhaust gas at the same time, which reduces the possibility of environmental pollution and protects the health of the staff. Compared with the existing technology, the applicability of the laser coding integrated equipment is improved.

[0044] Example 2: The difference between this example and Example 1 lies in the different structure of the adjustment component 5 .

[0045] Reference Figure 4 and Figure 5The adjustment assembly 5 includes a bidirectional screw 55, a limiting rod 56, and a movable base 57. The bidirectional screw 55 is rotatably connected to the frame 1 and is perpendicular to the conveying direction of the conveyor belt 11. The limiting rod 56 is fixedly connected to the frame 1 and is parallel to the bidirectional screw 55. Two movable bases 57 are provided between the limiting rod 56 and the bidirectional screw 55. The two movable bases 57 are arranged opposite each other, and the movable bases 57 are threadedly engaged with the bidirectional screw 55 and slidingly engaged with the limiting rod 56.

[0046] Reference Figure 4 and Figure 5 The movable base 57 is fixedly connected to a connecting block 571, which has a placement slot. A spring clip 572 is placed in the placement slot. A locking sleeve 573 is threadedly engaged with the connecting block 571, and the locking sleeve 573 presses against the spring clip 572. An extension rod is fixedly connected to the guide guardrail 4, and the extension rod passes through the connecting block 571 and the spring clip 572.

[0047] The staff passes the extension rod through the connecting block 571 and the spring clip 572 to move the guide guardrail 4 to the specified position, and then rotates the locking sleeve 573 to apply pressure to the spring clip 572. The spring clip 572 applies pressure to the extension rod to limit the extension rod. Then, the staff rotates the bidirectional screw 55 to move the movable seat 57, driving the guide guardrail 4 to move until the distance between the two guide guardrails 4 reaches the specified value, thereby achieving the effect of adjusting the distance between the two guide guardrails 4.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
