Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to a cable marking device. Background Technology

[0002] Cable lettering requires embossing, applied to the plastic insulation or sheath of the cable according to customer needs. The principle of embossing is to use an embossing wheel to press concave or convex lettering onto the heated surface of the cable's plastic structure, making the lettering an integral part of the cable's plastic structure. Compared to ink printing, which has poor adhesion to cable plastic structures and is prone to blurring or even flaking in outdoor high-temperature, humid, frictional, and corrosive liquid or gas environments, as well as after prolonged indoor use, causing difficulties in later cable installation and maintenance, embossed lettering offers superior performance. It is resistant to high temperatures, humidity, corrosion, and oily environments, ensuring that the lettering will not become unclear or flak off even after long-term use.

[0003] Traditional cable marking wheels engrave strings along the circumference of the wheel hub. This process requires precision machining tools, is difficult and inefficient, and the string and wheel are an inseparable unit. The length, character requirements, and character size of the cable marking strings constantly change according to customer needs. Because the traditional string and wheel are an inseparable unit, changes in string length, character requirements, or character size necessitate the manufacture of new marking wheels with different diameters. This results in problems such as single-use marking wheels, long production cycles, high material and processing costs, low efficiency, and high processing difficulty.

[0004] Therefore, those skilled in the art are dedicated to developing a variable-diameter, detachable cable printing device. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1 As shown, this invention provides a cable printing device, including a base plate 1. In this embodiment, the base plate 1 serves as a mounting foundation for supporting and connecting other functional components. To ensure its structural strength and durability, it is made of high-strength metal or engineering plastic. Its shape is circular, which facilitates uniform force distribution and stable rotation of the structure. In other embodiments, it can be set to an ellipse, polygon, or other irregular shape according to actual needs. In addition, the base plate 1 is provided with a shaft hole 11, and at least one spiral groove 12 is provided around the shaft hole 11 in the circumferential direction. The spiral groove 12 serves as a key guiding path, providing a guiding foundation for the movement of subsequent components. In this embodiment, there are five spiral grooves 12, evenly distributed along the circumference of the shaft hole 11. In other embodiments, other numbers of spiral grooves 12 can be provided according to actual needs.

[0024] like Figure 2 As shown, a limiter 2 is rotatably connected to the base plate 1. Specifically, the limiter 2 mainly includes a base 21, on which a connecting shaft 22 is provided. The base plate 1 is rotatably connected to the base 21 through the connecting shaft 22, thereby allowing the base 21 to rotate freely relative to the base plate 1. In addition, the base 21 is also provided with at least one slide rail 23 extending radially along the base 21. These slide rails 23 correspond one-to-one with the spiral grooves 12 on the base plate 1 in terms of position and number. The base 21 provides a mounting base for each slide rail 23, while the slide rails 23 ensure the guiding accuracy and stability of subsequent components during radial movement. In this embodiment, the number of slide rails 23 is the same as the number of spiral grooves 12, both being five, and these five slide rails are evenly distributed circumferentially along the base 21 to ensure balanced force transmission and structural symmetry.

[0025] like Figure 3As shown, spokes 3 are slidably connected to the limiter 2. Speakers 3 mainly include a slide rod 31 that slides in cooperation with the slide rail 23. In this embodiment, the sliding cooperation is a clearance cooperation. The slide rail 23 provides precise guidance and support for the radial movement of the slide rod 31, ensuring that the slide rod 31 can slide smoothly along the slide rail 23. Further, a connecting bolt 32 is provided at the end of the slide rod 31 near the base plate 1. This connecting bolt 32 extends towards the base plate 1 and passes through a corresponding helical groove 12 on the base plate 1, forming a sliding connection with the helical groove 12, allowing the connecting bolt 32 to slide freely along the helical groove 12 as the base plate 1 rotates. Simultaneously, to prevent the connecting bolt 32 from dislodging from the helical groove 12, a limiting block 32a is provided at the distal end of the connecting bolt 32 relative to the slide rod 31. The diameter of the limiting block 32a is larger than the width of the helical groove 12. The limiting block 32a ensures the stability and safety of the transmission process. In addition, an arc-shaped clamping plate 33 is provided at the end of the slide rod 31 away from the base plate 1, which provides a mounting base for subsequent components. During operation, when the base plate 1 is rotated, the spiral groove 12 rotates accordingly, thereby driving the connecting bolt 32 to move along the spiral groove 12. Through the combined guiding effect of the spiral groove 12 and the slide rail 23, the slide rod 31 is driven to slide radially along the slide rail 23, thereby realizing the adjustment of the diameter of the circle formed by the entire spoke 3 assembly.

[0026] like Figure 4 As shown, a variable diameter ring 4 is provided at the end of the spoke 3 away from the base plate 1. Specifically, the variable diameter ring 4 is securely clamped within the arc-shaped clamping plate 33. The arc-shaped clamping plate 33, as a clamping component, has an arc-shaped outer surface that matches the inner shape of the variable diameter ring 4. The variable diameter ring 4 is reliably fixed by fasteners (such as bolts, not shown in the figure) to ensure that it does not shift or loosen during the printing process. In this embodiment, the variable diameter ring 4 is made of silicone rubber. This material has excellent elastic deformation capacity and temperature resistance (the tolerance range is typically -50℃ to 250℃, much higher than the melting temperature of the sheath material of 130~210℃), allowing the variable diameter ring 4 to change its diameter and undergo corresponding elastic deformation as the spoke 3 moves radially, thereby smoothly and continuously adjusting its circumference to adapt to printing tapes 5 of different lengths. In other embodiments, other elastic materials of the same type can be selected according to actual needs, such as fluororubber, EPDM rubber, etc.

[0027] In addition, a printing strip 5 is fitted around the variable diameter ring 4. The printing strip 5 is used to engrave characters, and its two ends are welded and polished smooth.

[0028] In use, first, the desired string of characters is engraved on the printing tape 5 according to the printing requirements, and its length is accurately measured. Then, rotating the base plate 1 causes its spiral groove 12 to move relative to the connecting bolt 32, thereby driving multiple spokes 3 to move synchronously and smoothly radially under the guidance of the limiter 2. This adjusts the diameter of the reducing ring 4 until its circumference perfectly matches the length of the printing tape 5. Finally, the fasteners are tightened to securely lock the spokes 3 and the reducing ring 4 together. Next, the engraved printing tape 5 is tightly wrapped around the outer circumference of the reducing ring 4. Finally, the butt joints of the printing tape 5 are connected using welding and polished to a smooth finish to complete the installation.

[0029] This application features a novel structure that solves the problems of long manufacturing cycles, high material and processing costs, low efficiency, and high processing difficulty associated with traditional printing wheels through its variable diameter and separable design. Furthermore, this application is easy to operate and has low manufacturing costs, making it highly valuable for market promotion.
