Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a device for a thin, round rod-shaped segmented independent printing head. Background Technology

[0002] In modern industrial production, it is often necessary to print markings, serial numbers, patterns, or specifications on the surface of various slender, round rod-shaped workpieces.

[0003] The existing printing methods have the following shortcomings: 1. Low printing efficiency: Printing is mostly done by moving a single printhead back and forth along the workpiece axis. When printing on different sections of the workpiece, the printhead or workpiece needs to be moved frequently, resulting in a long printing cycle and low efficiency.

[0004] 2. Unstable workpiece positioning: Due to its circular cross-section, the thin, round rod is prone to rolling when placed on the worktable or displacement and vibration caused by the minute impact of inkjet printing. This instability easily leads to blurry printed content, positional misalignment, and low product qualification rate.

[0005] 3. Poor printing flexibility: Traditional all-in-one multi-head printers struggle to achieve independent, asynchronous control when printing different content at different positions on the same rod, or when processing multiple rods simultaneously with varying printing requirements. This makes them unable to meet the flexible and ever-changing production needs.

[0006] Therefore, how to provide a device that can efficiently, stably, and flexibly print segments of thin circular rods is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a segmented independent printing head device for thin round rods. This device, through its unique workpiece clamping and positioning structure and independently controlled multi-inkjet section design, aims to solve the problems of unstable positioning, low efficiency, and inflexible control during the printing of thin round rods.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A segmented, independent printer head device for thin, round rods includes a frame and further includes: a fixing plate slidably disposed at the bottom of the frame; a plurality of fixing seats arranged laterally and fixedly disposed on the fixing plate, the fixing seats being used to place round rods; a plurality of inkjet units disposed at the top of the frame, each inkjet unit corresponding to one fixing seat, and each inkjet unit being independently controllable; and a positioning part used to radially fix the round rods placed on the fixing seats.

[0009] In a preferred embodiment, the fixing base is provided with a plurality of fixing posts, and the plurality of fixing posts form a fixing space for placing the circular rod. This structure can provide a preliminary and stable support and positioning for the circular rod.

[0010] In a preferred embodiment, the positioning part includes a sliding seat, a limiting seat, and a cylinder; the fixed plate is provided with a slide rail that matches the sliding seat, and the sliding seat is slidably disposed on the slide rail. This structure clearly defines the core motion components of the positioning part.

[0011] In a preferred embodiment, the limiting seat is fixedly connected to the sliding seat; the cylinder is fixedly mounted on the frame, and the output end of the cylinder is connected to the sliding seat to drive the sliding seat to slide along the slide rail, and to cause the limiting seat to abut against and fix the circular rod. This structure details the complete motion transmission path from the power source to the clamping action, achieving stable and reliable radial clamping.

[0012] In a preferred embodiment, the contact surface on the limiting seat for abutting the circular rod is arranged perpendicular to the extending direction of the slide rail (31). This perpendicular arrangement ensures that the clamping force applied to the circular rod is a purely radial force, avoiding the generation of tangential components that could cause the workpiece to rotate or shift, and further enhancing the stability of the fixation.

[0013] In a preferred embodiment, the end of the limiting seat away from the sliding seat has an adapter hole, and the output end of the cylinder passes through the adapter hole and connects to the sliding seat. This structure provides a clever structural channel for the connection between the cylinder output end and the sliding seat, making the overall layout more compact and reasonable.

[0014] In a preferred embodiment, the inkjet unit includes a cavity, at least one inkjet head disposed at the bottom of the cavity, and at least one valve disposed on the cavity. The cavity is used to load ink, the printhead direction of the inkjet head faces the fixed plate, and the valve is used to control the inkjet action of the inkjet head. This structure details the specific internal structure for realizing independent inkjet printing function.

[0015] Beneficial effects Compared with the prior art, the present invention has the following significant advantages: Stable positioning and high printing accuracy: The circular rod is initially positioned by the fixing space on the fixed seat, and then the cylinder of the positioning part drives the limiting seat to actively compress radially, forming a stable "support-compression" double fixation, which effectively avoids the rolling and vibration of the thin circular rod during the printing process, and significantly improves the clarity and positional accuracy of the print.

[0016] High efficiency and flexibility: It is equipped with several independent inkjet units corresponding to each workstation, which can print multiple sections of a single rod or multiple rods at the same time. The printing task of each inkjet unit can be controlled by an independent valve, realizing parallel and asynchronous high-efficiency and flexible printing, which greatly shortens the production cycle.

[0017] Reasonable structure and convenient operation: The fixed plate adopts a sliding design, which makes it convenient for operators to load and unload workpieces in batches; the automatic clamping design of the positioning part reduces the complexity and labor intensity of manual operation.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a thin, round rod-type segmented independent printing head device of this utility model, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will be able to understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figures 1 to 5 This utility model provides a thin, round rod-type segmented independent printer head device, which mainly consists of a frame 1, several inkjet parts 2, a fixing plate 3, several fixing seats 4, and a positioning part 5.

[0029] The frame 1 is the supporting foundation of the entire device. It can be made of welded or cast metal profiles, providing a stable mounting base for other components.

[0030] The fixing plate 3 is located at the bottom of the frame 1 and is slidably connected to the frame 1 via guide rails and other structures. During operation, the fixing plate 3 can be pulled out from the frame 1 to facilitate the operator to place or remove the round rod workpiece. After loading, it is pushed back into the printing station inside the frame 1.

[0031] In this embodiment, multiple fixing seats 4 are provided, arranged laterally at equal intervals, and securely fixed to the upper surface of the fixing plate 3 by bolts or other means. Each fixing seat 4 is used to support a circular rod. Specifically, as shown... Figure 2As shown, each fixed base 4 has four fixed posts 41 arranged in a V-shape on its upper surface, which naturally form a V-shaped fixation space 42. When the circular rod is placed, its arc-shaped outer wall is in tangential contact with two fixed posts 41, thereby achieving a stable initial axial and radial positioning.

[0032] The inkjet units 2 are located on the top of the frame 1, and their number corresponds to the number of mounting bases 4. The vertical projection of each inkjet unit 2 is directly opposite the mounting base 4 below it. Each inkjet unit 2 has the same structure, as shown below. Figure 1 As shown, the device includes a cavity 21 for storing ink. One or more (two in the example) inkjet heads 23 are mounted on the bottom of the cavity 21, with the nozzles of the inkjet heads 23 facing the mounting base 4 directly below. Valves 24 are also installed on the cavity 21, each valve 24 independently controlling the ink flow of one inkjet head 23. Each valve 24 can be independently controlled by an external control system (not shown), thus enabling independent printing control of each inkjet head 23, allowing it to print different content at different times. The top of the cavity is threadedly connected to the top of the frame 1 for fixation.

[0033] The positioning part 5 is a key mechanism for achieving stable workpiece clamping. It mainly comprises an assembly of several sets of sliding seats 51 and limiting seats 52, and a cylinder 53 as a power source. On the fixed plate 3, a slide rail 31 is formed parallel to the arrangement direction of the fixed seats 4. A sliding seat 51 is correspondingly provided next to each fixed seat 4, and the bottom of the sliding seat 51 matches the slide rail 31, allowing it to slide smoothly along the direction of the slide rail 31. The limiting seat 52 is fixedly connected to the sliding seat 51 by means of threaded locking, forming a moving unit. The limiting seat 52 has a flat abutment surface on the side facing the fixed seat 4, which is perpendicular to the extension direction of the slide rail 31, i.e., perpendicular to the sliding direction of the sliding seat 51. The cylinder body of the cylinder 53 is fixedly mounted on the frame 1, and its piston rod (output end) points towards the sliding seat 51. In this embodiment, as... Figure 3 As shown, the limiting seat 52 has an adapter hole 521, through which the output end of the cylinder 53 passes and its end is connected to the sliding seat 51. In this way, when the cylinder 53 is activated, its output end will push the sliding seat 51, thereby causing the limiting seat 52 fixed thereto to move along the slide rail 31.

[0034] Workflow Description: Feeding: The output end of the starting cylinder 53 is extended, and the fixing plate 3 is slid out from the bottom of the frame 1. The operator places the thin round rods to be printed one by one into the retention space 42 of each fixing seat 4.

[0035] Advancement: Push the fixed plate 3, which is fully loaded with workpieces, into the printing station of the frame 1. At this time, each round rod is located directly below the corresponding inkjet part 2.

[0036] Clamping and positioning: The actuating cylinder 53 is activated by air supply, and its output end retracts, pushing the sliding seat 51. The sliding seat 51 drives the limiting seat 52 to move along the slide rail 31 towards the fixed seat 4. Finally, the abutting surface of the limiting seat 52 presses tightly against the side wall of the circular rod, firmly fixing the circular rod in the three-point clamping space formed by the two fixed posts 41 and the limiting seat 52. Since the abutting surface is perpendicular to the direction of movement, pure radial pressure is applied, ensuring that the circular rod will not roll or move axially, and the positioning is extremely stable.

[0037] Independent printing: When the valve 24 corresponding to the inkjet unit 2 that needs to be printed is opened, the inkjet head 23 connects and sprays ink droplets onto the surface of the circular rod that is firmly fixed below, forming the desired pattern or text. Since each inkjet unit 2 is independently controllable, selective printing, synchronous printing, or asynchronous printing at any station can be achieved.

[0038] Release and Unloading: After printing is complete, cylinder 53 reverses its direction, extending its output end and causing the limit seat 52 to disengage from the circular rod. At this point, the fixing plate 3 can be slid out again to remove the printed workpiece and begin a new round of loading, completing one work cycle.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
