Description

Technical Field

[0001] This invention belongs to the field of spraying and relates to a marking device, specifically a two-tube marking device. Background Technology

[0002] Separation, quality tracking, and management. Currently, this printing work still relies entirely on manual operation, resulting in a significant bottleneck in overall efficiency. Due to the limited speed of manual printing and the susceptibility of operators to fatigue and varying levels of skill, it is difficult to maintain a consistently high-speed and stable work rhythm, making the printing process one of the potential factors restricting the overall assembly progress.

[0003] Furthermore, manual printing methods suffer from significant uncertainty in terms of quality consistency. Different operators vary in their control of the angle, distance, and speed of the handheld printing equipment, and even the same operator cannot perfectly replicate the same printing action across different shifts or time periods. This fluctuation in human factors can easily lead to problems such as positional shifts in the printed content, uneven ink density, blurred fonts, or incomplete edges, directly affecting the clarity and readability of the printed code. In the long run, the instability of printing quality not only increases the risk of misreading but also places an additional burden on subsequent quality inspection verification, component traceability, and process management, ultimately potentially affecting the overall traceability and quality control level of the product. Summary of the Invention

[0013] The specific content of the present invention will be further explained in detail below with reference to the embodiments. Detailed Implementation

[0015] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0016] This invention provides a marking device for a two-piece cylindrical body, comprising a frame 1, a cylindrical body support mechanism 2, a flipping mechanism 3, and a marking mechanism 4; The cylinder support mechanism 2 includes a first linear module 2-1 and a support roller 2-5 arranged sequentially on the frame 1 in the transverse direction; a support base plate 2-2 is provided on the slider of the first linear module 2-1, and the end of the support base plate 2-2 extends out of the first linear module 2-1 and is placed on the support roller 2-5; a first support seat 2-3 and a second support seat 2-4 are respectively provided on the top two sides of the support base plate 2-2. The tilting mechanism 3 includes multiple lifting guide shafts 3-3 fixed to the frame 1 and passing through the bottom of the frame 1, and multiple lifting cylinders 3-2; the bottom ends of the multiple lifting guide shafts 3-3 are collectively fitted with a base plate pull plate 3-1; the piston rods at the top of the multiple lifting cylinders 3-2 are collectively provided with a base plate 3-4; the bottoms of the multiple lifting cylinders 3-2 pass through the base plate pull plate 3-1; a pair of moving units are symmetrically arranged on both sides of the top of the base plate 3-4, and each moving unit includes a guide rail pad parallel to the top of the base plate 3-4. 3-5 and longitudinal movement cylinder 3-7, the guide rail pad 3-5 is provided with a longitudinally distributed guide rail 3-6, the guide rail 3-6 is provided with a cylinder mounting plate 3-8, the lateral rear side of the cylinder mounting plate 3-8 is connected to the top of the piston rod of the longitudinal movement cylinder 3-7; the top of the cylinder mounting plate 3-8 is provided with a rotary cylinder 3-9, the rotary cylinder 3-9 is provided with a gripper cylinder 3-10, and the gripper cylinder 3-10 is provided with a gripper 3-11; the two grippers 3-11 in a pair of moving units are arranged opposite each other; The coding mechanism 4 includes a mounting bracket 4-1 mounted on the frame 1. A second linear module 4-2 distributed laterally is provided on the top of the mounting bracket 4-1. A printhead lifting cylinder 4-3 is provided on the slider of the second linear module 4-2. The piston rod of the printhead lifting cylinder 4-3 is set downward and a printhead connecting plate 4-4 is provided on it. A printhead 4-5 is provided on one side wall of the printhead connecting plate 4-4 and a swing cylinder 4-6 is provided on the other side. The swing cylinder 4-6 is connected to the printhead 4-5. An ink cartridge mounting plate 4-8 is provided on the printhead connecting plate 4-4. An ink cartridge 4-7 is provided on the ink cartridge mounting plate 4-8. The ink cartridge 4-7 contains bagged ink. The bagged ink in the ink cartridge 4-7 is connected to the printhead 4-5 through a hose.

[0017] In the above technical solution, the double cylinder is stably and reliably fixed and supported by the cylinder support mechanism; the inkjet printing mechanism prints relevant marks on the cylinder surface according to a preset program; furthermore, after printing on one side is completed, the double cylinder is smoothly and accurately flipped to a predetermined angle by the flipping mechanism so that the inkjet printing mechanism can continue to print on the other side of the cylinder. This effectively solves the multiple problems caused by relying entirely on manual printing in the prior art: it not only significantly improves the overall efficiency of the printing operation and shortens the processing cycle of a single product, but also completely eliminates the quality fluctuations caused by human operation differences through mechanized precision control, ensuring that all printed products can meet the predetermined process standards in terms of clarity, positional accuracy and appearance consistency, thereby fundamentally overcoming the technical defects of low efficiency and inability to guarantee quality consistency in manual printing.

[0018] In addition, the bagged ink is connected to the printhead through an ink guide tube. The printhead is designed with an opening and closing valve. The ink jet is controlled by controlling the opening and closing of the valve, and the ink output is controlled by controlling the duration of the valve opening and closing. The ink output speed is a fixed speed, which is the valve size. The working process of the above technical solution is as follows: The manual person places the two-piece cylinder 5 to be processed onto the first support seat 2-3 and the second support seat 2-4 of the cylinder support mechanism 2; the slider of the second linear module 4-2 moves laterally forward and reaches the starting point of the designated printing position. When the printhead lifting cylinder 4-3 extends downward and drives the printhead 4-5 to descend to the preset height H above the first cylinder, the printhead 4-5 begins to print the required content. At the same time, the second linear module 4-2 continues to move laterally forward until the first line of printing content is completed. If there is a second line of printing content, the second linear module 4-2 moves laterally to the rear and returns to the printing starting point. The swing cylinder 4-6 moves a certain distance longitudinally to the front, causing the printhead to swing at an angle. The coding mechanism 4 starts printing and completes the first cylinder printing. The longitudinal movement cylinder 3-7 of the flipping mechanism 3 extends, causing the gripper 3-11 to reach the left and right sides of the double cylinder. The gripper cylinder 3-10 closes, driving the gripper 3-11 to clamp the double cylinder from both sides. The two lifting cylinders 3-2 extend upwards simultaneously, driving the base plate 3-4 to rise. Then the rotating cylinder 3-9 starts to rotate, driving the gripper cylinder 3-10, gripper 3-11, and the clamped double cylinder 5 to rotate 180°. The two lifting cylinders 3-2 retract and open, and the double cylinder 5 is placed on the first support seat 2-3 and the second support seat 2-4. The longitudinal movement cylinder 3-7 retracts, and the inkjet printing mechanism 2 begins to print on the second cylinder. After the printing operation is completed on both cylinders, the No. 1 linear module 2-1 starts to move, driving the support base plate 2-2, the No. 1 support seat 2-3, the No. 2 support seat 2-4 and the double cylinder 5 to move laterally forward until they reach the unloading position and wait for unloading.

[0019] Furthermore, the frame 1 includes a frame body 1-2, a panel 1-3 is provided on the top of the frame body 1-2, and a support foot 1-3 is provided on the frame body 1-2.

[0020] In the above technical solution, the frame 1 has a simple and lightweight structure, making it easy to move and install.

[0021] Furthermore, the nozzle connecting plate 4-4 has two arc-shaped moving grooves 4-11, each containing a deep groove ball bearing 4-12. A first connecting plate 4-13, which is fixedly connected to the deep groove ball bearing 4-12, is located on the rear lateral side of the nozzle connecting plate 4-4. A swing cylinder 4-6 is fixed on the connecting plate 4-13. A second connecting plate 4-10, which is fixedly connected to the deep groove ball bearing 4-12, is located on the front lateral side of the nozzle connecting plate 4-4. A nozzle 4-5 is fixed on the second connecting plate 4-10 via a U-shaped clamping plate 4-9.

[0022] In the above technical solution, when the swing cylinder 4-6 moves, the deep groove ball bearing 4-12 is driven to shift at a certain angle along the arc-shaped moving groove 4-11 on the nozzle connecting plate 4-4 via the first connecting plate 4-13, thereby causing the nozzle 4-5 to swing at a certain angle, which facilitates the adjustment of the angle of the nozzle 4-5.

[0023] Furthermore, the lifting guide shaft 3-3 includes a bearing seat fixed to the frame, and a guide shaft fixed to the base plate pull plate 3-1 is movably disposed in the bearing seat.

[0024] In the above technical solution, the lifting guide shaft 3-3 can be raised and lowered through the bearing housing and guide shaft.

[0025] Furthermore, a vertical plate is provided on the top of the cylinder mounting plate 3-8, and a rotary cylinder 3-9 is provided on the vertical plate.

[0026] In the above technical solution, by setting a vertical plate, the rotary cylinder 3-9 has a certain height, which makes it easier to drive the gripper 3-11 to rotate.
