Description

Technical Field

[0001] This invention relates to the field of shipbuilding plate marking and processing technology, specifically to a dedicated guiding device for ship steel plate information transfer equipment. Background Technology

[0002] In the shipbuilding process, it is often necessary to neatly mark key information such as ship number, section number, map number, and specifications on the edge of the shipbuilding plates. Currently, the shipbuilding industry commonly uses the EBS250 inkjet printer to print and transfer material information on the shipbuilding plates.

[0003] Currently, existing inkjet printers typically require manual hand-held printing. Without guidance and positioning during the printing process, manual hand-held printing easily results in tilted or skewed information, leading to poor labeling and affecting information readability. Furthermore, when boards are stacked in a leaf-like pattern, the lack of orderly positioning can obscure the printed information, requiring material handlers to repeatedly flip through boards to verify information, significantly increasing labor costs and working time. Additionally, the lack of protective support at the front of the printing equipment allows the printhead to directly contact and rub against the boards, causing printhead wear and shortening the equipment's lifespan.

[0004] Based on this, the present invention designs a guiding device for ship steel plate information transfer equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a guiding device for ship steel plate information transfer equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a guiding device for ship steel plate information transfer equipment, comprising: A metal pad made of hard metal is installed at the rigid connection between the guide device and the inkjet printer body; A guide shaft made of bearing steel is fixed parallel to the assembly position reserved in the metal pad; Bearings are respectively fitted onto the ends of the two guide shafts to form a rolling guide assembly; A limiting component made of bearing steel is movably mounted on the front end of the guide shaft and contacts the inner ring surface of the bearing; The roller assembly is symmetrically arranged in the mounting groove reserved in the metal pad, and its front protrudes out of the mounting groove by a certain gap. Locking threaded rods made of stainless steel are fixedly installed on their respective guide shafts.

[0007] As a preferred embodiment of the present invention, the metal pad includes: The plate serves as the mounting base for the entire device. Symmetrical shaft holes are formed on the plate, and the diameter of the shaft holes is equal to the diameter of the guide shaft. A strip groove is formed in the middle of the plate body along its length, and the strip groove communicates with the shaft hole; The through-slot penetrating the plate is rectangular in shape.

[0008] As a preferred embodiment of the present invention, the guide shaft further includes: The mounting hole is threadedly connected to the limiting member, and the threaded through hole is threadedly connected to the locking threaded rod. The threaded through hole is opened through one side of the guide shaft.

[0009] As a preferred embodiment of the present invention, the limiting member includes: A baffle with an internal hexagonal groove is provided, the diameter of which is slightly smaller than the diameter of the inner ring of the bearing; A threaded post is fixedly connected to the center of one side of the baffle, and the threaded post is screwed into the mounting hole.

[0010] As a preferred embodiment of the present invention, the roller assembly includes: A cylindrical rubber roller, wherein a rubber layer is provided on the outer side of the rubber roller; A rotating shaft that is movably inserted into the rubber roller, the diameter of the rotating shaft being the same as the diameter of the through hole.

[0017] The following will refer to the appendices in the embodiments of the present invention. Figure 1-8The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example Please see Figure 1-8 The present invention provides the following technical solution: a guiding device for ship steel plate information transfer equipment, comprising a metal pad 1, a guide shaft 2, a bearing 3, a limiting component 4, a roller assembly 5, and a locking threaded rod 6.

[0019] The metal pad 1 serves as the mounting base for the entire device. It is made of hard metal and is located at the rigid connection between the guide device and the inkjet printer body. Specifically, the metal pad 1 includes a plate body 101, a shaft hole 102, a strip groove 103, a through groove 104, a through hole 105, and a threaded hole 106. The plate 101 has symmetrical shaft holes 102 on the left and right sides, the diameter of which is equal to the diameter of the guide shaft 2, for mounting the guide shaft 2; A strip groove 103 is formed in the middle of the plate 101 along its length and communicates with the shaft hole 102 to provide installation and adjustment space; The through slot 104 is rectangular in structure and runs through the plate 101, and is symmetrically arranged on the left and right sides; The bottom of the through groove 104 is provided with a through hole 105, and the top of the through groove 104 is provided with a threaded hole 106.

[0020] The guide shafts 2 are made of bearing steel, and there are two of them. They are fixed in parallel within the pre-drilled shaft holes 102 in the metal pad 1. The guide device is fixedly installed in the guide wheel gap of the EBS250 inkjet printer through the two guide shafts 2, forming a rigid connection between the bracket and the inkjet printer. Each guide shaft 2 includes: The mounting hole 201 located at the front end of the guide shaft 2 is used for threaded connection with the limiting member 4.

[0021] A threaded through hole 202 is provided on one side of the guide shaft 2 to lock the threaded connection of the threaded rod 6. The threaded rod 6 is used to lock the connection with the inkjet printer and also allows for fine adjustment of the position of the bearing 3 on the inkjet printer for ship plates of different thicknesses and sizes.

[0022] Bearing 3 is the core of the rolling guide assembly and is respectively fitted onto the ends of the two guide shafts 2. In this embodiment, a 626RS bearing is used.

[0023] The limiting component 4 is also made of bearing steel, and is movably installed at the front end of the guide shaft 2 and contacts the inner ring surface of the bearing 3. It is used for axial limiting to prevent the bearing 3 from falling off. Its specific structure is as follows: A baffle 401 with an internal hexagonal groove has a diameter slightly smaller than that of the inner ring of the bearing 3, and is used to block and limit the inner ring of the bearing 3.

[0024] A threaded post 402 is fixedly connected to the center of one side of the baffle 401. The threaded post 402 is screwed into the mounting hole 201 of the guide shaft 2 to achieve a fixed connection between the limiting member 4 and the guide shaft 2.

[0025] The roller assemblies 5 are symmetrically arranged within the pre-reserved through grooves 104 of the metal pad 1, with the front rubber roller portion protruding from the through grooves 104 by a certain gap, to isolate the metal pad 1 from the plate and prevent scratches from forming between the metal pad 1 and the plate. Each roller assembly 5 includes: The cylindrical rubber roller 501 is wrapped with a rubber layer on the outside and serves as a rolling friction component that contacts the sheet metal.

[0026] The rotating shaft 502, which is movably inserted into the rubber roller 501, has the same diameter as the through hole 105 of the metal pad 1. The rotating shaft 502 is rotatably connected to the inner hole of the rubber roller 501 through its own shaft. The rotating shaft 502 is screwed into the threaded hole 106 with a threaded head 5021 at one end, and a rotating head 5022 is provided at the other end for easy rotation and disassembly.

[0027] The locking threaded rod 6 is made of stainless steel and is installed in the threaded through hole 202 opened on the side of the corresponding guide shaft 2. By screwing into the threaded through hole 202 of the guide shaft 2, the entire guide device is locked to the inkjet printer body, which is convenient for installation and disassembly. At the same time, it has a fine-tuning effect in the reserved assembly position. The locking threaded rod 6 also includes a rubber gasket 601 sleeved and installed on the end cap of the locking threaded rod 6, so that it forms a surface contact with the inkjet device for fixation, increasing friction and preventing scratches on the equipment.

[0028] The working principle and usage process of this invention: First, the operator fixes the special guide device in the gap of the guide wheel of the EBS250 inkjet printer through its assembly structure (i.e., the connection point between the locking threaded rod 6 and the inkjet printer body), ensuring that the metal pad 1 is rigidly connected to the inkjet printer body and the structure is stable and without loosening. Then, the operator holds the EBS250 inkjet printer and smoothly attaches the bearing 3 at the end of the guide device to the side edge of the ship steel plate (plate) to be printed. At this time, the rolling guide assembly consisting of two guide shafts 2 and bearings 3 forms a stable straight contact baseline with the edge of the plate, maintaining stable contact between the bearings 3 and the edge of the plate. The operator moves the inkjet printer horizontally and at a uniform speed. During the movement, relying on the rigid support of the guide device and the rolling guide effect of the bearings, the printhead path of the inkjet printer is strictly limited to a straight line parallel to the edge of the plate, thus completing a neat and horizontal information printing transfer at the edge of the plate. For ship plates of different thicknesses or widths, the entire guide device (support) can be finely adjusted and slid along the assembly position on the inkjet printer body by loosening the locking thread rod 6 outward, changing the extension distance of the bearings 3 relative to the printhead. After adjustment, tighten the locking thread rod 6 to fix it. This design allows the device to flexibly adapt to the standardized printing needs of various specifications of boards. During the printing process, the rubber roller 501 protruding in front of the metal pad 1 will contact the board surface before the metal pad 1, isolating the printhead from the board. The rubber roller 501 moves in contact with the board by rolling friction, effectively avoiding direct scratching between the printhead and the board surface. This protects the printing equipment (especially the expensive printhead) and prevents scratches on the board surface caused by the movement of the guide device.

[0029] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
