Description

Technical Field

[0001] This application belongs to the field of inkjet printing device technology, specifically an inkjet printing device with automatic lifting and flexible connection. Background Technology

[0002] Product identification is an indispensable and crucial step in modern industrial production lines, and inkjet printers are widely used as key equipment for printing identification information on products or their packaging. Currently, most inkjet printers on the market adopt a fixed structure, meaning the printhead position is fixed, and the product must be moved under the printhead to complete the marking process.

[0003] Traditional fixed inkjet printers require manual adjustment of the product height to match the position of the inkjet nozzle when dealing with products of varying heights. This cumbersome process consumes significant time and manpower, and human error can easily lead to inaccurate product positioning, affecting coding quality. Furthermore, when used on products with irregular surfaces, fixed inkjet printers struggle to guarantee clear and complete coding. The inability to flexibly adjust the relative position of the inkjet nozzle to the product surface often results in misaligned, blurred, or even missed coding, severely impacting production efficiency and the standardization of product marking. In addition, fixed inkjet printers hinder forklift operations after coding, increasing the complexity of production logistics and failing to meet the demands of modern, diverse, and efficient production. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this application provides an automatic lifting flexible connection inkjet printer that can automatically adjust the relative position of the inkjet printer head to the product according to the product's height, enabling the inkjet printer head to quickly adjust to a suitable relative position with the product.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic lifting flexible connection inkjet printer, comprising: a controller, a bracket, a lifting system, a laser rangefinder, a mounting box, and an inkjet printer. The lifting system includes a concentric shaft, a rotating concave wheel connected based on the concentric shaft, a lifting rope with its end fixed inside the rotating concave wheel, and a servo motor for driving the concentric shaft. The concentric shaft, the servo motor, and the laser rangefinder are mounted on the bracket. The lifting rope is connected to both ends of the mounting box based on a V-shaped connecting rope. The inkjet printer is mounted inside the mounting box based on a spiral guide rail, and the inkjet printer moves based on the limited movement of the spiral guide rail. The controller is electrically connected to the laser rangefinder, the servo motor, and the inkjet printer.

[0006] Among them, the lifting ropes are connected by horizontal ropes, and the horizontal ropes are equipped with a hub pipe based on a movable slip ring. Various external connecting pipes are arranged inside the hub pipe.

[0007] The bracket is also equipped with a camera, which is connected to a monitor, and the monitor is connected to the controller.

[0008] Among them, the corresponding rotating concave wheel is equipped with an anti-slip plate, which is used to limit the range of motion of the lifting rope.

[0009] The inkjet printer is equipped with an emergency lift button.

[0010] The beneficial effects of this application are:

[0011] This application provides an automatic lifting and flexible connection inkjet printer. Based on real-time and precise measurement of product height using a laser rangefinder, and combined with intelligent control by a PLC, the inkjet printer head can automatically, quickly, and accurately adjust to the appropriate relative position with the product without manual intervention. This significantly improves inkjet printing efficiency, reduces labor costs and the risk of operational errors, and ensures high-quality inkjet printing results for products of different heights. Employing a flexible connection method, through a combination of steel wire rope and inverted V-shaped connecting rope, the inkjet printer can flexibly adjust its position in three-dimensional space, closely conforming to irregular product surfaces to achieve precise positioning and printing. This ensures maximum clarity and completeness of the printed characters, significantly improving the inkjet printer's adaptability to complex products and broadening its application range.

[0017] like Figure 1 As shown, the automatic lifting inkjet printer includes a bracket 1, an anti-skid board 2, a lifting rope 3, an inverted V-shaped connecting rope 4, a spiral guide rail 5, a camera 6, a rotating concave wheel 7, a hub 8, a concentric shaft 9, a laser rangefinder 10, an inkjet printer 11, a servo motor 12, a movable slip ring 13, an inkjet printer mounting box 14, an emergency lifting button 15, a monitor 16, and a controller 17.

[0018] A concentric shaft 9 is mounted on the bracket 1, and two rotating concave wheels 7 are connected by the concentric shaft 9. The concentric shaft 9 is driven by a servo motor 12, which is mounted on the bracket 1. A lifting rope 3 is installed inside the rotating concave wheel 7, and an anti-jump plate 2 is installed corresponding to the lifting rope 3, both mounted on the bracket 1. A laser rangefinder 10 is mounted on the bracket 1, with its center aligned horizontally with the mounting box 14. It can automatically adjust the relative position of the inkjet nozzle and the product according to the product's height, improving inkjet printing efficiency. After measuring the distance using the laser rangefinder 10, the lifting system controls the motor to drive the concentric shaft via the controller 17, thereby achieving height adjustment. When the rotating concave wheel is working, the lifting rope 3 retracts and expands within the groove as the concave wheel rotates. The anti-jump plate 2, by setting a blocking structure next to the concave wheel, restricts the range of motion of the lifting rope 3, ensuring that it can only operate normally within the groove, thus ensuring the stability and reliability of the equipment.

[0019] The lifting rope 3 has its first end fixed inside the rotating concave wheel 7, and its second end connected to the inverted V-shaped connecting rope 4. The inverted V-shaped connecting rope 4 is connected to both sides of the inkjet printer mounting box 14. The bottom of the mounting box 14 is open, and the inkjet printer 11 is mounted in the middle via a spiral guide rail 5. The spiral guide rail 5 is connected to a motor, allowing the position of the inkjet printer 11 within the mounting box 14 to be adjustable. The mounting box 14 is positioned advantageously in the x, y, and z three-dimensional space, enabling the inkjet printer 11 to perform relative positioning on products with irregular surfaces. The inkjet printer can flexibly adjust its position in three-dimensional space, closely conforming to the surface of irregular products to achieve precise positioning and ensure that the printed characters are maximized in clarity and completeness.

[0020] A horizontal lifting rope is connected between the two lifting ropes 3. A movable slip ring 13 is suspended on the horizontal lifting rope and connected to the hub 8 through the movable slip ring 13. The hub 8 moves back and forth horizontally along the spiral guide rail 5 with the inkjet printer 11. External conduits such as communication lines, high-voltage air ducts, power lines, and ink tubes are connected to the hub 8, which supports the back and forth movement of the inkjet printer and achieves protection and neat layout of the conduits.

[0021] A camera 6 is also installed on the bracket 1, which monitors the clarity of the printed characters and the printing process in real time via a monitor 16, and allows for traceability of the printing quality. Through video monitoring, this operation can be automated and the printing quality can be monitored. After the printer completes printing, it automatically rises to the top to ensure safe transport by forklifts. For ease of use on site, an emergency lifting button 15 is provided for convenient emergency lifting.

[0022] Finally, it should be noted that the units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0023] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
