Description

Technical Field

[0001] This invention relates to the field of cable printing technology, and in particular to a cable printing device with follow-up correction function and its usage method. Background Technology

[0002] In the cable manufacturing process, printing on the outer sheath is a crucial step, primarily used to print core information such as the cable model, manufacturer, meter number, and applicable standards. Clear and complete printing is essential for cable product traceability, specification differentiation, and quality control. It also provides precise guidance for subsequent cable laying, maintenance, and repair work, effectively preventing cable misconnections and misuse, ensuring the safe operation of power and communication lines, and is an indispensable step in standardized production within the cable industry.

[0003] Currently available cable marking equipment suffers from numerous technical shortcomings, with insufficient intelligence and adaptability. Existing marking equipment only supports fixed-position marking, unable to adjust the marking position in real time based on cable transport offset, cable curvature, and production conditions, and lacks dynamic character correction functionality. When slight swaying or offset occurs during cable production, problems such as skewed, misaligned, blurred, or deformed characters easily arise, significantly reducing the clarity and standardization of the markings. Furthermore, existing equipment uses a single, fixed marking method, only adapting to the marking needs of cables with fixed specifications and materials, failing to accommodate processing scenarios with cables of different diameters and sheath materials, thus severely limiting its applicability. These issues result in low yield rates and poor versatility in cable marking, making it difficult to meet the diversified and high-precision production demands of modern cables. Additionally, dust and ink generated during laser marking and inkjet printing easily accumulate in the marking area and inside the equipment, contaminating the marking surface and affecting clarity, further exacerbating the aforementioned problems and hindering the upgrading and development of intelligent cable processing technology. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing cable printing equipment only supports fixed-position printing and cannot adjust the printing position in real time according to the cable conveying offset, cable curvature and production conditions. When the cable swings and shifts slightly, problems such as skewed, misaligned, blurred and deformed characters will occur. At the same time, the printing method is single and fixed, which cannot be adapted to cables of different diameters and different sheath materials, resulting in low printing yield and poor versatility.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a cable printing device with follow-up correction function, including a bottom support frame, a horizontal cable guide tube for conveying cables, a laser printing module and an inkjet coding module; the horizontal cable guide tube is composed of a central tube, a left tube and a right tube, a first rotating adjustment seat for installing the laser printing module is provided between the central tube and the left tube, and a second rotating adjustment seat for installing the inkjet coding module is provided between the central tube and the right tube. Strip-shaped flip-out openings are provided on both sides of the outer wall of the central tube, the right side of the outer wall of the left tube and the left side of the outer wall of the right tube. Electrically controlled flip-out support wheels are movably assembled inside the strip-shaped flip-out openings. Optical calibration modules are installed on the first rotating adjustment seat and the second rotating adjustment seat.

[0006] Furthermore, there are integrated annular guide rails between the central cylinder and the left cylinder, as well as between the central cylinder and the right cylinder.

[0007] Furthermore, both the first and second rotary adjustment seats are provided with arc-shaped operating ports.

[0008] Furthermore, the inner side of the arc-shaped operating port has an inwardly protruding inner mounting bracket. The laser printing module is fixed to the first rotating adjustment seat bolt via the inner mounting bracket, and the ink inkjet printing module is fixed to the second rotating adjustment seat bolt via the inner mounting bracket.

[0009] Furthermore, an external transmission assembly is fixedly installed on the arc-shaped operating port of the first and second rotary adjustment seats.

[0010] Furthermore, an annular rack is provided on the outer arc-shaped surface of the annular guide rail to cooperate with the external transmission assembly.

[0011] Furthermore, the outer ends of the strip-shaped flip-out opening have outer mounting brackets for movably assembling electrically controlled flip-out support wheels. The electrically controlled flip-out support wheel includes a flip-out adjusting arm movably mounted on the outer mounting bracket, an external support rod for controlling the flip-out adjusting arm, and an adjusting support wheel movably mounted on the end of the flip-out adjusting arm.

[0012] Furthermore, a bottom-mounted control cabinet and a bottom-mounted dust collection box are fixedly installed on the side wall of the bottom support frame, and an annular guide hood for connecting the bottom-mounted dust collection box is fixedly assembled around the outer periphery of the central cylinder.

[0013] Furthermore, the present invention also discloses a method of using the above-mentioned printing device: the operator inserts the cable from the left end opening of the left cylinder or the right end opening of the right cylinder, and then guides the cable sequentially along the central cylinder, the left cylinder, and the right cylinder. Then, the external support rod flips the extension control tilting adjustment arm into the strip tilting opening, pressing the adjustment support wheel against the outer wall of the cable, adapting to different cable specifications and controlling the position of the cable inside the central cylinder, the left cylinder, and the right cylinder. Then, the adjustment support wheel starts to rotate synchronously, controlling the cable to be guided sequentially along the central cylinder, the left cylinder, and the right cylinder. While the cable is being transported, the laser printing module and the inkjet printing module print on the surface of the cable as needed. During the printing process, the external transmission component meshes with the ring rack, driving the first and second rotating adjustment seats to rotate, correcting the position of the laser printing module and the inkjet printing module, ensuring printing accuracy, and performing large-area printing operations.

[0014] Furthermore, during the printing process, dust and ink dust are generated inside the horizontal cable guide tube. The air pump installed inside the bottom dust collection box draws the air out of the horizontal cable guide tube through the annular guide shroud, filters it inside the bottom dust collection box, and then discharges it into the environment.

[0015] The beneficial effects of this invention are as follows: the optical calibration module, in conjunction with the external transmission component and the ring rack, drives the rotating adjustment seat to rotate, thereby correcting the printing position accordingly. Even when the cable swings and deviates, the characters remain clear, improving the printing yield. The electrically controlled flip support wheel presses the adjustment support wheel against the outer wall of the cable, adapting to different cable specifications and controlling stable material feeding, thus expanding the scope of application. The bottom-mounted dust collection box, in conjunction with the ring guide hood and the air pump, removes and filters dust and ink in real time, ensuring printing quality and equipment operational reliability.

[0023] See Figures 1-5 The cable printing device with follow-up correction function in this embodiment includes a bottom support frame 100, a horizontal cable guide tube 200, a laser printing module 500, an inkjet coding module 510, an optical calibration module 400, an electrically controlled flip support wheel 600, a bottom control cabinet 700, and a bottom dust collection box 710. The horizontal cable guide tube 200 is fixedly mounted above the bottom support frame 100 and is used to transport the cable to be printed.

[0024] The horizontal cable guide cylinder 200 consists of a central cylinder 210, a left cylinder 220, and a right cylinder 230. The central cylinder 210 is located in the middle, the left cylinder 220 is located to the left of the central cylinder 210, and the right cylinder 230 is located to the right of the central cylinder 210. A first rotating adjustment seat 300 is provided between the central cylinder 210 and the left cylinder 220 for mounting the laser printing module 500; a second rotating adjustment seat 310 is provided between the central cylinder 210 and the right cylinder 230 for mounting the inkjet coding module 510. There are integrated annular guide rails 250 between the central cylinder 210 and the left cylinder 220, and between the central cylinder 210 and the right cylinder 230. The first rotating adjustment seat 300 and the second rotating adjustment seat 310 are respectively movably mounted on the corresponding annular guide rails 250 and can rotate around the axis of the horizontal cable guide cylinder 200.

[0025] Both the first rotary adjustment seat 300 and the second rotary adjustment seat 310 have arc-shaped operating ports 320, and the inner side of the arc-shaped operating port 320 has an inwardly protruding inner mounting bracket 330. The laser printing module 500 is bolted to the first rotary adjustment seat 300 through the inner mounting bracket 330, and the inkjet printing module 510 is bolted to the second rotary adjustment seat 310 through the inner mounting bracket 330. The bolt fixing method facilitates the disassembly, assembly, maintenance and replacement of the printing modules. An external transmission assembly 340 is also fixedly installed on the arc-shaped operating port 320 of the first rotary adjustment seat 300 and the second rotary adjustment seat 310. An annular rack 260 that cooperates with the external transmission assembly 340 is provided on the outer arc-shaped surface of the annular guide rail 250. The external transmission assembly 340 includes a drive motor and an output gear. The output gear meshes with the annular rack 260. When the drive motor is running, it drives the first rotary adjustment seat 300 or the second rotary adjustment seat 310 to rotate along the annular guide rail 250 around the axis of the horizontally placed cable tube 200 through the output gear, thereby adjusting the circumferential position of the printing module.

[0026] Strip-shaped flip-up openings 240 are provided on both sides of the outer wall of the central cylinder 210, the right side of the outer wall of the left cylinder 220, and the left side of the outer wall of the right cylinder 230. The strip-shaped flip-up openings 240 extend along the axial direction of the cylinder. The outer ends of the outer openings of the strip-shaped flip-up openings 240 have outer mounting brackets 350, and electrically controlled flip-up support wheels 600 are movably mounted inside the strip-shaped flip-up openings 240. The electrically controlled flip-up support wheel 600 includes a flip-up adjusting arm 610, an external support rod 620, and an adjusting support wheel 630. The flip-up adjusting arm 610 is movably mounted on the outer mounting bracket 350 and can swing around the mounting point. The external support rod 620 is an electric push rod, one end of which is connected to the flip-up adjusting arm 610 to control the flip-up action of the flip-up adjusting arm 610. The adjusting support wheel 630 is movably mounted on the end of the flip-up adjusting arm 610, and a drive motor is provided on the flip-up adjusting arm 610 to drive the adjusting support wheel 630 to rotate synchronously.

[0027] A bottom-mounted control cabinet 700 and a bottom-mounted dust collection box 710 are fixedly installed on the side wall of the bottom support frame 100. The bottom-mounted control cabinet 700 has a built-in controller and drive circuit, which are used to control the extension and retraction of the external support rod 620, adjust the rotation of the support wheel 630, and operate the external transmission assembly 340. An annular guide shroud 720 is fixedly assembled around the central cylinder 210. The annular guide shroud 720 is connected to the bottom-mounted dust collection box 710, and an air pump is installed inside the bottom-mounted dust collection box 710.

[0028] The method of using the device of the present invention is as follows: The operator inserts the cable from the left end opening of the left cylinder 220 or the right end opening of the right cylinder 230, and then guides the cable sequentially along the central cylinder 210, the left cylinder 220, and the right cylinder 230. After the cable is inserted, the bottom control cabinet 700 controls the extension of the external support rods 620 of each electrically controlled tilting support wheel 600. The external support rods 620 push the tilting adjustment arm 610 to tilt inward into the strip-shaped tilting opening 240, pressing the adjustment support wheel 630 against the outer wall of the cable. The pressing position of the adjustment support wheel 630 can be automatically adjusted according to the cable diameter, which can not only adapt to cables of different specifications, but also control the position of the cable inside the central cylinder 210, the left cylinder 220, and the right cylinder 230 to prevent the cable from being eccentric or offset.

[0029] The image acquisition unit of the optical calibration module 400 acquires cable images in real time, and the image processing unit performs feature recognition on the images to identify the cable's outer diameter and axis position. The controller built into the bottom control cabinet 700 calculates the target extension / retraction amount of each external support rod 620 based on the identified cable outer diameter, and controls the extension / retraction of the external support rods 620. The external support rods 620 push the tilting adjustment arm 610 to rotate around the installation point to the corresponding angle, causing the adjusting support wheel 630 to adhere to the cable's outer wall with a preset pressing force, thus completing the automatic adjustment of the pressing position. Multiple electrically controlled tilting support wheels 600 are arranged at axial intervals along the transverse cable guide drum 200. The controller controls the synchronous extension / retraction of each external support rod 620, ensuring that the pressing force of each adjusting support wheel 630 on the cable remains consistent. The cable is uniformly constrained in the circumferential direction, and the cable axis coincides with the axis of the transverse cable guide drum 200, thereby ensuring the cable is transported in a centered position and preventing cable eccentricity or deviation.

[0030] Subsequently, the adjusting support wheel 630 begins to rotate synchronously. The friction between the adjusting support wheel 630 and the outer wall of the cable drives the cable to sequentially follow the central cylinder 210, left cylinder 220, and right cylinder 230. Simultaneously with cable transport, the laser printing module 500 and the inkjet printing module 510 print on the surface of the passing cable as needed. The laser printing module 500 is suitable for ablating permanent markings onto the cable surface, while the inkjet printing module 510 is suitable for printing variable information on the cable surface. The two modules work together to complete the printing of different marking contents.

[0031] The optical calibration module 400 includes an image acquisition unit and an image processing unit, with the image acquisition unit facing the printing area on the cable surface. During printing, the optical calibration module 400 acquires images of the cable surface and the printing area in real time through the image acquisition unit. The image processing unit performs feature recognition on the acquired images to identify the cable's transport position, the printing start position, and the printing offset. When cable swaying, offset, or printing position deviation is detected, the bottom control cabinet 700 calculates the rotation direction and angle of the external transmission assembly 340 based on the offset and controls the operation of the external transmission assembly 340. The external transmission assembly 340 meshes with the annular rack 260, driving the first rotary adjustment seat 300 and the second rotary adjustment seat 310 to rotate along the annular guide rail 250, thereby correcting the circumferential position of the laser printing module 500 and the inkjet printing module 510, ensuring that the printing position is always aligned with the area to be printed on the cable surface. Once the printing position deviation reaches zero, the external transmission component 340 stops rotating. This closed-loop feedback process is executed cyclically at a fixed time during cable transport, achieving continuous follow-up correction of the printing position to ensure printing accuracy. At the same time, by rotating the adjustment seat, the printing module can cover a large area around the cable circumference, enabling large-area printing operations.

[0032] During the printing process, dust and ink dust are generated inside the horizontal cable guide tube 200. The air pump installed inside the bottom dust collection box 710 draws the air out of the horizontal cable guide tube 200 through the annular guide shroud 720. The dust and ink dust enter the bottom dust collection box 710 with the airflow. After being filtered inside the bottom dust collection box 710, the clean air is discharged into the environment, which avoids dust and ink dust contaminating the printing area and affecting the printing quality. At the same time, it prevents dust accumulation from affecting the reliability of equipment operation.

[0033] The above embodiments are merely illustrative of the technical concept of the present invention and are not intended to limit its scope of protection. Any equivalent modifications or obvious variations made by those skilled in the art to the above embodiments without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
