Description

Technical Field

[0001] The present invention relates to the technical field related to laser inkjet printers, and in particular to a laser inkjet printer. Background Art

[0002] Laser inkjet printer is a marking device that uses software to control and vaporize laser directly on the surface of an object. Laser inkjet printer uses software to deflect the laser beam and uses the high temperature of the laser to directly burn the surface of the product to be marked to form fonts or patterns. This mark is permanent and cannot be erased, and can be intuitively distinguished without the help of any auxiliary tools, making it easy for consumers to identify. Therefore, it is widely used in food, beverage, medicine, beauty, electronics, home appliances, automobile manufacturing and other fields. With the growing demand of consumers for product traceability, anti-counterfeiting identification and brand awareness, the demand for laser inkjet printers in these industries continues to rise;

[0003] After searching, the application number is 202411200139.0. A workpiece production surface inkjet printer with a smoke exhaust and cooling function includes a support frame and a conveyor belt installed in the support frame. A laser inkjet mechanism is installed on the middle rear side of the support frame, and the outer side of the opening and closing door is connected to the inner wall of the protective frame through a sealing cover in an inverted "U" shape. The workpiece production surface inkjet printer with a smoke exhaust and cooling function improves the sealing of the protective frame on all sides when it is in use, and prevents smoke and tiny particles generated by the inkjet printer from escaping outward during use. It is then convenient to use the smoke exhaust frame, the smoke exhaust pipe and the external exhaust fan in the later stage to thoroughly discharge and clean the smoke and tiny particles in the protective frame, which not only prevents smoke and tiny particles from falling on the workpiece, but also keeps the working environment clean, thereby improving the quality of the inkjet printer's coding and marking operation on the workpiece surface;

[0004] Although the above-mentioned inkjet printer can remove the smoke during the inkjet printing process, the inkjet printer often has uneven inkjet printing during the inkjet printing process. Since the traditional inkjet printer is an automated setting, the staff will not observe the uniformity of the inkjet printing for a long time during the inkjet printing process. Once the inkjet printing is found to be uneven, the traceability work cannot be carried out. A large number of accumulated products need to be re-inspected to find the number of products with uneven inkjet printing. The entire traceability inspection work requires a lot of manpower and time, and the operation is too troublesome.

[0005] Another example is the laser positioning device for an inkjet printer with application number 202420527681.6. Although a limiting mechanism is provided to limit the product, the limiting mechanism can only limit block-shaped products, and cannot limit sheet-shaped paper boxes and packaging bags. Therefore, the use scope of the entire inkjet printer is too limited. Summary of the invention

[0006] The purpose of the present invention is to provide a laser inkjet printer to solve the problem raised in the above background technology that the inkjet printers currently on the market often have uneven coding when inkjet printing.

[0049] See also Figure 1-11 , the present invention provides a technical solution: a laser inkjet printer, including a fixing assembly, which includes a supporting base plate 1 and a fixing frame 2, and the top of the supporting base plate 1 is provided with a fixing frame 2, which is used for fixing and supporting the entire inkjet printer;

[0050] The conveying mechanism 3 is arranged at the top of the fixed frame 2 and is used for conveying the product;

[0051] The coding device is arranged at the middle position of the top of the conveying mechanism 3, and comprises a fixed frame 5 and a coding component 7, and the coding component 7 is arranged inside the fixed frame 5;

[0052] Also includes;

[0053] The limiting mechanism 4 has two groups symmetrically arranged at the top of the conveying mechanism 3, and is used for limiting the position of sheet and block products;

[0054] The collecting mechanism 6 is arranged at the top of the conveying mechanism 3. The collecting mechanism 6 is rotatable and has multiple collecting components distributed at equal angles on its outer side for collecting equal amounts of products.

[0055] The present application provides a laser inkjet printer with a collecting mechanism 6 with equal amount of collecting components. Specifically, when in use, first, the entire inkjet printer is fixed to the ground under the action of the supporting base plate 1, and then the conveying mechanism 3 inside the fixed frame 2 is started, and the product is placed on the top of the conveying mechanism 3, so that it moves with the conveying mechanism 3. Since a limiting mechanism 4 is arranged above the conveying mechanism 3, the product is limited and conveyed. When the product is conveyed to the bottom of the inkjet component 7 inside the fixed frame 5, the positioning laser inkjet coding work can be completed by the inkjet component 7. After the inkjet coding is completed, the product will reach the collecting component inside the collecting mechanism 6 for collection. When a collecting component is full, the collecting mechanism 6 is controlled to rotate, and another empty collecting component is rotated to the top of the conveying mechanism 3 for collection again. At this time, the staff can collect the product just collected on the outside.

[0056] Among them, according to Figure 1-2 As shown, the conveying mechanism 3 includes a conveying motor 31, a conveying belt 32 and two rotating rollers 33. The conveying belt 32 is arranged outside the two rotating rollers 33, and the conveying motor 31 is coaxially connected to the top end of one side of one rotating roller 33.

[0057] The cross section of the fixing frame 2 is arranged in a "U"-shaped structure, and a conveying mechanism 3 is arranged inside the "U"-shaped structure;

[0058] Specifically, when the conveying mechanism 3 is working, it is necessary to start the conveying motor 31 so that it drives the rotating roller 33 at its top to rotate. When the rotating roller 33 rotates, the conveyor belt 32 performs the conveying work to complete the conveying work of the product.

[0059] In this application, when the product needs to be limited, according to Figure 3-4As shown, the limiting mechanism 4 includes two supporting components 41, a rotating mechanism 42, a limiting component 43, a rotating motor 44 and a rotating sleeve 45. The two supporting components 41 are symmetrically arranged at the top of one side of the fixing frame 2, and the rotating mechanism 42 is connected to the inner bearing of the top, the rotating mechanism 42 is externally threadedly connected to the rotating sleeve 45, and the limiting component 43 is connected in the middle of the symmetrically arranged rotating sleeve 45, and the outer side of the rotating mechanism 42 is driven to rotate by the rotating motor 44;

[0060] The support assembly 41 includes a fixed seat 411, a first cylinder 412 and a connecting frame 413. The bottom of the fixed seat 411 is installed on the top of the fixed frame 2, and the inside of the fixed seat 411 is a hollow structure. The first cylinder 412 and the connecting frame 413 are connected inside the hollow structure. The top of the connecting frame 413 is connected to the bearing of the rotating mechanism 42.

[0061] The rotating mechanism 42 is configured to install a screw rod 421, the outer portion of which is threadedly connected to the rotating sleeve 45;

[0062] The limiting assembly 43 includes a limiting plate 431 and a limiting roller 432. The limiting plate 431 is configured as a structure with two sides tilted upward and a middle horizontal structure, and the limiting rollers 432 are evenly spaced at the top of the middle horizontal structure.

[0063] Specifically, when it is necessary to limit the position of the sheet-shaped packaging bag or paper box product, the product is placed horizontally at the bottom of the limiting plate 431, and then the product is conveyed along with the conveying mechanism 3, so that the limiting plate 431 will squeeze the product above the product to complete the work of limiting the product;

[0064] When it is necessary to limit the position of a block product, the product only needs to be placed between the limiting rollers 432 above the two limiting plates 431. Therefore, when the conveying mechanism 3 conveys the product, the limiting rollers 432 will squeeze the product on both sides of the product, thereby completing the product limiting work.

[0065] Among them, when it is necessary to adjust the height of the limit assembly 43, it is necessary to start the first cylinder 412 inside the fixed seat 411, so that it drives the connecting frame 413 to adjust the height, so that the rotating mechanism 42 on the inner side of the connecting frame 413 changes in height. Since a movable limit assembly 43 is arranged above the rotating mechanism 42, the height adjustment work of the limit assembly 43 is completed. When it is necessary to adjust the position of the limit assembly 43, it is necessary to start the rotating motor 44, so that it drives the installation screw rod 421 at its top to rotate, thereby making the installation screw rod 421 and the rotating sleeve 45 threadedly connected, thereby making the rotating sleeve 45 drive the limit assembly 43 on its outer side to change its position.

[0066] Furthermore, when equal amounts of collection are required, Figure 5 and Figure 9-11 The collecting mechanism 6 includes a rotating shaft 61, a servo motor 67 and a collecting assembly. The top end of the servo motor 67 is coaxially connected to the rotating shaft 61, and the collecting assemblies are distributed at equal angles outside the rotating shaft 61.

[0067] The collecting assembly includes a rotating plate 62, a connecting seat 63, an extrusion assembly 64, a blocking mechanism 65 and a supporting mechanism 66. The rotating plates 62 are distributed at equal angles outside the rotating shaft 61, and a connecting seat 63 with an isosceles triangle structure is integrally installed on the top of the rotating plate 62. Extrusion assemblies 64 are arranged on the inner sides of the two waists of the isosceles triangle outside the connecting seat 63. A storage space is formed between adjacent rotating plates 62 and connecting seats 63, and a rotatable supporting mechanism 66 is also arranged at the bottom for support.

[0068] The extrusion assembly 64 includes a second cylinder 641 and a push plate 642. The second cylinder 641 is disposed in a groove on the inner side of the connection seat 63, and the top end of the second cylinder 641 is connected to the push plate 642.

[0069] Two groups of blocking mechanisms 65 are symmetrically arranged at the bottom of the connecting seat 63, and the blocking mechanism 65 includes a reset shaft 651 and a limit pin 652. A limit pin 652 is arranged on the outer side of the reset shaft 651. The limit pin 652 is arranged to support the bottom of the supporting mechanism 66.

[0070] The support mechanism 66 includes a support plate 661, a fixed shaft 662 and a torsion spring 663. A through hole is provided at the top of the support plate 661. A torsion spring 663 is provided inside the through hole and connected to the fixed shaft 662. Both sides of the fixed shaft 662 are fixed on the surface of the rotating plate 62.

[0071] Specifically, when collecting, it is necessary to start the servo motor 67 first, so that it drives the rotating shaft 61 at its top to rotate, and then the rotating shaft 61 drives the collection component to rotate. After the position corresponds to the position of the conveying mechanism 3, after the product is stenciled, it will fall to the storage space formed by the rotating plate 62 and the connecting seat 63. Since the bottom is provided with a support mechanism 66 for support, the product will be piled up on the top of the support mechanism 66. At this time, the second cylinder 641 can be started to drive the push plate 642 to move. Since the push plates 642 are symmetrically arranged inside the placement space, they can squeeze the two sides of the accumulated products to complete the neat placement work. After a certain amount of accumulation, the servo motor 67 is controlled to drive the placement component to rotate again, and the product accumulation work inside another placement component can be carried out;

[0072] When the placement component needs to be unloaded after stacking is completed, it is necessary to manually control the limit pin 652 at the bottom to rotate under the action of the reset shaft 651. After the obstruction of the support mechanism 66 is released, the support plate 661 is controlled to rotate around the fixed shaft 662 to unload the material. After that, as the torsion spring 663 is reset, it is blocked by the limit pin 652 and the product stacking work can be carried out again.

[0073] In this application, when printing, according to Figure 7-8 As shown, the coding assembly 7 includes a control motor 71, a mounting plate 72, a lifting mechanism 73 and a coding mechanism 74. The lifting mechanism 73 is arranged in the reserved grooves on both sides of the fixed frame 5, and the mounting plate 72 is connected in the middle of the lifting mechanism 73. The top of the mounting plate 72 is provided with a control motor 71, and the bottom of the control motor 71 is connected to the coding mechanism 74. The coding mechanism 74 is used for coding the product;

[0074] The lifting mechanism 73 includes a lifting motor 731, a connecting screw 732 and a limit rod 733. The top of the lifting motor 731 is coaxially connected to the connecting screw 732, and the outer side of the connecting screw 732 is threadedly connected to the two sides of the mounting plate 72, and two limit rods 733 are also arranged on both sides of the connecting screw 732, and the limit rods 733 pass through the mounting plate 72.

[0075] The inkjet printing mechanism 74 includes a connecting plate 741, an optical path 742, a galvanometer 743 and a field mirror 744. The top of the connecting plate 741 is connected to the control motor 71, and the optical path 742 is arranged below the connecting plate 741. The galvanometer 743 is installed at the top of the optical path 742, and the field mirror 744 is arranged at the bottom of the galvanometer 743.

[0076] Specifically, when positioning the inkjet printer, it is necessary to start the lifting motor 731 so that it drives the connecting screw rod 732 at its top to rotate, thereby making it threadedly connected with the mounting plate 72. Since the mounting plate 72 is limited by the limiting rod 733, the mounting plate 72 drives the inkjet printer mechanism 74 above it to move up and down. Then, starting the control motor 71 again will make its top penetrate the bottom of the mounting plate 72 and drive the connecting plate 741 to rotate, thereby changing the position of the optical path 742 at the bottom of the connecting plate 741, thereby changing the angles of the galvanometer mirror 743 and the field lens 744, and then the inkjet printer can be operated.

[0077] In the present application, the optical path 742 includes optical devices such as lasers and beam expanders. The laser beam is first emitted from the laser, and then the beam diameter is expanded by the beam expander to adapt to the subsequent optical system. The function of the beam expander is to adjust the diameter and divergence angle of the laser beam so that the beam can reach the required spot size and uniformity after focusing. The galvanometer 743, also known as the scanning mirror, is a key component in the laser marking system. It consists of two reflectors, which control the deflection of the laser beam on the X-axis and Y-axis respectively. The computer controls the reflection angles of the two reflectors to achieve precise positioning and scanning of the laser beam on the working surface. The principle of the galvanometer 743 is that after receiving the position signal, the swing motor galvanometer 743 will swing a certain angle according to the conversion ratio of voltage and angle to achieve precise deflection of the laser beam. The galvanometer 743 scanning marking system is capable of vector marking and dot matrix marking, and has the characteristics of fast response speed and high marking speed. The field lens 744, also known as the F-Theta lens or flat field focusing lens, focuses the laser beam deflected by the galvanometer 743 onto the working surface. The special design of the field lens 744 makes the laser beam uniform in size and focal depth after focusing within a certain working range, which is crucial to achieving high-quality marking effects. The parameters of the field lens 744 include the incident pupil, focal length, etc. The size of the entrance pupil needs to be greater than or equal to the spot of the galvanometer 743 to ensure the uniformity and range of marking;
