Description
Technical Field
[0001] This utility model relates to the technical field of marking steel components, and in particular to a handheld fluorescent inkjet printer for steel components. Background Technology
[0002] Steel components mainly refer to steel components such as beams, columns, and slabs. Since there are many components in steel structure projects, and they are often similar in shape, confusion and errors can easily occur. Text marking can clearly distinguish different components, avoid misuse and incorrect installation due to similar components, help reduce the impact of human factors on the project, and improve the accuracy and reliability of the project. Among them, the text marking methods for steel components are usually mechanical engraving, electro-etching, or manual engraving, which are not only costly but also relatively inefficient.
[0003] In existing technologies, some steel components lack written markings and are only registered in purchase documents or lists. This makes it difficult for construction workers to identify the steel components during on-site construction. Therefore, simple markings are usually made on unmarked steel components using markers to enable quick identification. However, some steel components are exposed after construction, and marking them with markers can affect the building's aesthetics. Furthermore, it is difficult to remove these markings. Additionally, the lack of a unified marking management system means that only the marking personnel can identify the marked steel components, which is detrimental to construction.
[0004] Therefore, an inkjet printer can be used to apply invisible inkjet markings to the equipment, and then the markings can be identified by illuminating them with the light corresponding to the fluorescent ink under an ultraviolet lamp. This does not affect the appearance of the markings. However, this method still has some problems that need to be improved:
[0005] 1. When using an inkjet printer for marking, if the area to be marked on the steel component is small, the guide wheel of the inkjet printer cannot be fully placed in the marking area, which will cause the inkjet printer to be unable to make stable marking in the marking direction, resulting in poor marking effect.
[0006] 2. During inkjet printing, the printing effect cannot be visually observed, which may lead to poor printing results and the inability to stop printing in time when reprinting is required, thus consuming fluorescent ink and increasing costs.
[0007] Therefore, there is an urgent need for a coding device to improve the above problems. Utility Model Content
[0008] The purpose of this invention is to provide a handheld fluorescent inkjet printer for steel components to improve the aforementioned technical problems.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0051] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0052] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and 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 orientation, and therefore should not be construed as a limitation of this utility model.
[0053] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.
[0054] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0055] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0056] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0057] It should be understood that when using inkjet printer 1 for marking, if the area of the steel component to be marked is small, the guide wheel of inkjet printer 1 cannot be fully placed in the marking area, which will result in poor marking effect of inkjet printer 1.
[0058] Furthermore, if the coding effect is poor due to rust, dust, or errors in the coding operation, it needs to be re-coded. Since the coding effect cannot be observed directly and in a timely manner, the coding operation cannot be stopped in time, thus consuming fluorescent ink and increasing costs.
[0059] To address the aforementioned issues, this embodiment provides a handheld fluorescent inkjet printer for steel components, mainly comprising an inkjet printer 1 and two guide members 2. This device is primarily used for fluorescent inkjet printing on steel components.
[0060] like Figure 1 As shown, the inkjet printer 1 includes a housing 11 and a hand grip 12. The hand grip 12 is disposed on the lower surface of the housing 11, and is located at the end of the housing 11 away from the inkjet nozzle. A display control screen is provided on one side of the housing 11 for displaying the inkjet text. The hand grip 12 is provided with a spray button 13. When inkjet printing, the finger presses the spray button 13 to perform the inkjet printing operation.
[0061] The text can be edited via USB flash drive, external computer, etc. The basic printing functions of the inkjet printer 1, as well as the undescribed related components in the housing 11 and hand grip 12, all adopt existing technologies and will not be elaborated further.
[0062] In this embodiment, the inkjet uses invisible fluorescent ink, which avoids having a significant impact on the appearance of the steel component, while also allowing for identification by the developing lamp 6. The developing lamp 6 can be different devices such as ultraviolet lamps or infrared lamps depending on the ink.
[0063] In this embodiment, the inkjet nozzle is located on the end face of one end of the housing 11, and the housing 11 can adopt a rectangular or trapezoidal structure according to actual usage requirements. In this embodiment, for ease of description, the housing 11 adopts a rectangular shape.
[0064] In this embodiment, as Figures 1-3 As shown, guide members 2 are provided on both sides of the housing 11. Specifically, the guide member 2 includes a rotating rod 21 and a rotating base 22. The two rotating bases 22 are respectively arranged opposite to each other on the two sides of the housing 11. One end of each of the two rotating rods 21 is provided with multiple guide balls 23, and the other end is respectively arranged on the two rotating bases 22. The two rotating bases 22 can rotate around a direction perpendicular to the two sides of the housing 11.
[0065] In this embodiment, as Figures 1-3 As shown, the rotating base 22 includes a rotating bearing base 221 and a rotating column 222. The two rotating bearing bases 221 are disposed opposite to each other on the two sides of the housing 11, and the lower surface is in contact with the side surface of the housing 11. The two rotating bearing bases 221 are both disposed near the end of the inkjet printer 1 that is being printed. The two rotating bearing bases 221 rotate around a direction perpendicular to the two sides of the housing 11.
[0066] In this embodiment, one end of the rotating column 222 is disposed on the rotating bearing base 221 and is coaxially disposed with the rotating bearing base 221, thereby enabling the rotating column 222 to rotate around the direction perpendicular to both sides of the housing 11.
[0067] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the rotating rod 21 includes a rod body 211 and a connecting plate 212. The rod body 211 adopts a cylindrical structure, and one end is vertically set on the side of the connecting plate 212. The axis of the rod body 211 is perpendicular to the symmetrical center line of the side of the connecting plate 212 and intersects it, so that the connecting plate 212 is subjected to relatively uniform force.
[0068] Among them, such as Figure 1 , Figure 3 and Figure 9 As shown, a plurality of guide balls 23 are evenly distributed on the sides of the two connecting plates 212 away from the rotating column 222, and the plurality of guide balls 23 on the same connecting plate 212 are arranged sequentially at intervals along the extension direction of the two intersecting sides of the side of the connecting plate 212.
[0069] The connecting plate 212 has diagonal braces 24 at both ends of its side, and the other ends of the two diagonal braces 24 are respectively set opposite to the rod body 211, so that the rod body 211 and the two diagonal braces 24 jointly support the connecting plate 212.
[0070] In this embodiment, the rotating column 222 is provided with a insertion hole 222a that penetrates the rod body 211. The axis of the insertion hole 222a intersects with the axis of the rotating column 222 and is perpendicular to each other. One end of the rotating rod 21 can be slidably inserted into the insertion hole 222a. The upper end face of the rotating column 222 is provided with a fixing hole 222b along the extension direction of the axis, and the fixing hole 222b passes through the insertion hole 222a. The rotating rod 21 is provided with a first connecting hole 211a and a second connecting hole 211b that penetrate the rod body 211. The axes of the first connecting hole 211a and the second connecting hole 211b intersect with the axis of the rod body 211 and are perpendicular. Specifically, the axial orientations of the first connecting hole 211a and the second connecting hole 211b are the same and parallel to the axial orientation of the rotating column 222. The first connecting hole 211a and the second connecting hole 211b are spaced apart, and the first connecting hole 211a is close to the connecting plate 212.
[0071] In this embodiment, the device also includes a fixing rod 3, which has a cylindrical structure and is adapted to the fixing hole 222b, the first connecting hole 211a, and the second connecting hole 211b.
[0072] In this embodiment, after the rod 211 passes through the insertion hole 222a of the rotating column 222, the first connecting hole 211a or the second connecting hole 211b can be aligned with the fixing hole 222b depending on the usage. Specifically, when there is enough surface space for printing, the rotating column 222 is rotated so that the insertion hole 222a of the rotating column 222 faces the printing direction and is perpendicular to the end face of the printing end of the housing 11. Then, the rod 211 is inserted into the insertion hole 222a, so that the first connecting hole 211a is aligned with the insertion hole 222a. Then, one end of the fixing rod 3 is sequentially inserted into the fixing holes 222. The upper part of b, the first connecting hole 211a, and the lower hole wall of the fixing hole 222b are abutted, so that the end of the rod body 211 with the connecting plate 212 faces the direction of inkjet printing, and the axis of the rod body 211 is perpendicular to the end face of the inkjet printing end of the housing 11, and the multiple guide balls 23 on the side of the connecting plate 212 face the direction of inkjet printing. When inkjet printer 1 is used for inkjet printing, the guide balls 23 abut against the surface to be inkjet printed, and the end face of the inkjet printing end of the housing 11 has a small gap with the surface to be inkjet printed, so that inkjet printer 1 can perform inkjet printing operation stably.
[0073] The method of inserting one end of the fixing rod 3 into the fixing hole 222b and the first connecting hole 211a, or inserting one end of the fixing rod 3 into the fixing rod 3 and the second connecting hole 211b, can be determined according to the inkjet surface and the usage scenario.
[0074] In this embodiment, the rotating column 222 can be rotated so that the rod 211 faces upward, i.e., the axis of the rod 211 is perpendicular to the upper surface of the housing 11. At this time, the rod 211 is inserted into the insertion hole 222a, and when one end of the rod 211 faces the direction perpendicular to the marking on the housing 11, the fixing hole 222b passes through the second connecting hole 211b, and one end of the fixing rod 3 passes through the upper end of the fixing hole 222b and the second connecting hole 211b in sequence, and abuts against the hole wall at the lower end of the fixing hole 222b. If the steel components have mutually perpendicular... For straight surfaces, such as L-shaped steel or I-beams, one side of the rod 211 can be rotated upwards, and the other side of the rod 211 can be oriented towards the coding direction. Then, the coding machine 1 is oriented towards one of the surfaces of the steel component, so that the multiple guide balls 23 at one end of the rod 211 facing the coding direction abut against that surface, and the other rod 211 abuts against another surface. This guides the coding machine 1 from different directions, allowing it to stably code along a straight line, resulting in a stable and better coding effect.
[0075] The rotating column 222 can be rotated according to the structure of the steel component, so that the rod 211 faces the direction of coding or is perpendicular to the upper surface of the shell 11. This makes the coding effect of the inkjet printer 1 stable and applicable to a variety of usage scenarios.
[0076] In some embodiments, the device further includes a positioning rod 4, with a first positioning hole 211c at one end of the rod body 211 away from the connecting plate 212, and the housing 11 is provided with two second positioning holes 111, wherein the axial directions of the first positioning hole 211c and the two second positioning holes 111 are perpendicular to the two side surfaces of the housing 11.
[0077] When the rotating column 222 drives the rotating rod 21 to rotate toward the coding direction or perpendicular to the coding direction, the positioning rod 4 passes through the first positioning hole 211c and one of the second positioning holes 111, or the first positioning hole 211c and another second positioning hole 111, respectively, thereby positioning the rotation angle and orientation of the rod body 211, so that the rod body 21 can be rotated relatively easily and accurately.
[0078] In this embodiment, one end of the positioning rod 4 can be threaded to two second positioning holes 111 respectively, thereby stabilizing the position of the rod body 211.
[0079] In some embodiments, the lower surface of the connecting plate 212 is attached to the surface of the housing 11. The side of the connecting plate 212 facing the rotating column 222 is provided with a plurality of fixing plates 213. The lower side of the fixing plates 213 is attached to the surface of the housing 11 and is connected by bolts. The plurality of fixing plates 213 are arranged sequentially at intervals along the extension direction of the intersection line between the connecting plate 212 and the housing 11. Specifically, the fixing plates 213 are provided with a plurality of first bolt holes 213a, and the housing 11 is provided with a plurality of second bolt holes 113. When the connecting plate 212 rotates to a preset position, the plurality of first bolt holes 213a on the plurality of fixing plates 213 are aligned with the plurality of second bolt holes 113 respectively, so that the fixing plates 213 and the housing 11 can be connected by bolts, thereby fixing the connecting plate 212 and making the position of the connecting plate 212 stable when the inkjet printer 1 is printing.
[0080] In some embodiments, the device further includes two lamp holders 5, which are disposed opposite to each other on both sides of the housing 11, and the opposite sides of the lamp holders 5 and the housing 11 are parallel to each other. A developing lamp 6 is provided on the side of the lamp holders 5 facing the inkjet printing. The developing lamp 6 can be an ultraviolet lamp, an infrared lamp, etc., and can be selected according to the inkjet printing ink.
[0081] In this embodiment, the upper and lower ends of the lamp holder 5 facing the side of the housing 11 are provided with sliding protrusions 7 perpendicular to the side. The two sliding protrusions 7 of the same lamp holder 5 are arranged opposite to each other on the upper and lower sides of the housing 11, thereby forming a U-shaped structure with the lamp holder 5 and the two sliding protrusions 7, and the opening facing the side of the housing 11, thus reserving installation space for the rotating column 222 and other structures, thereby avoiding mutual obstruction between the lamp holder 5 and the rotating column 222 and other structures.
[0082] Two sliding protrusions 7 are slidably connected to the upper and lower surfaces of the housing 11, respectively, with the sliding direction facing the direction of inkjet printing. Specifically, each sliding protrusion 7 has a slide rail 8 on its lower side facing the housing 11. The slide rail 8 is laid along the inkjet printing direction, and the slide rail 8 has a slider 9. The sliding protrusion 7 and its lower slide rod are connected through the slider 9, so that the lamp holder 5 slides back and forth along the slide rail 8. When inkjet printing is performed, the two lamp holders 5 are slid to the end closer to the inkjet printing, so that the developing lamp 6 can irradiate the inkjet printing. This allows the inkjet printing personnel to observe the inkjet printing effect while printing, thereby ensuring the inkjet printing effect and avoiding the increased cost caused by repeated inkjet printing.
[0083] A control switch 51 is provided on the surface of the lamp holder 5 away from the housing 11. The two control switches 1 are electrically connected to the two developing lamps 6 respectively, and are used to control the opening and closing of the developing lamps 6. The two developing lamps are electrically connected to the power supply of the spraying device through the two control switches 51 and the spraying button 13 respectively.
[0084] In this embodiment, when printing, the direction of movement of the inkjet printer 1 is first determined, and then the developing lamp 6 on the side of the housing 11 opposite to the direction of movement of the inkjet printer 1 is turned on by the control switch 51. Then, the printing button 13 is pressed, the developing lamp is turned on and provides illumination, and the printing operation is performed at the same time. This allows the developing lamp 6 to be turned on at the same time when printing, which facilitates the operation of the printing personnel.
[0085] In this embodiment, the sliding protrusion 7 is provided with a connecting bolt 10 at one end away from the lamp holder 5. The upper surface of the housing 11 is provided with four threaded holes 112, and all four threaded holes 112 are located between two slide rails 8. Two of the threaded holes 112 are located at both ends of one side of one slide rail 8, and the other two threaded holes 112 are located at both ends of the other slide rail 8. Specifically, when the slide rail 8 slides to one end of the inkjet printing, one end of the connecting bolt 10 is connected to the threaded hole 112 on its lower side, thereby fixing the lamp holder 5.
[0086] In this embodiment, when inkjet printing is required, firstly, the two rotating columns 222 are rotated so that the rod body 211 inserted into the two rotating columns 222 is oriented in a preset position. Then, the developing lamp 6 on one side is turned on according to the displacement direction of the inkjet printer 1. Then, the lamp holder 5 is slid along the slide rail 8 to one end of the inkjet printing, and the corresponding connection switch is turned on at the same time. Finally, the inkjet printing operation is performed.
