Description

Technical Field

[0001] The utility model relates to the field of natural gas pipeline marking, in particular to a mold used for spray printing on natural gas pipelines. Background Art

[0002] During the printing and marking operation of natural gas pipelines, the printing mold needs to be placed on the part of the natural gas pipeline to be printed, so that the printing mold is in contact with the outer wall of the natural gas pipeline as much as possible. The text or pattern hollowed out on the printing module allows the dye to display specific text or pattern on the natural gas pipeline. Currently, the printing molds used are sticker molds or stainless steel molds.

[0003] However, the sticker mold needs to be pasted on the natural gas pipeline, and it is difficult to tear it off after spraying. The plasticity of the stainless steel mold is poor, and it cannot be used for printing on natural gas pipelines of different diameters, and the printed pattern is easily displaced on the natural gas pipeline. Both the sticker mold and the stainless steel mold need to be pre-engraved with text or patterns for printing, and the text or pattern cannot be changed after engraving. For the many pipe sections with different markings at natural gas stations, the same printing mold can be reused few times, and the mold engraving consumes a lot of cost. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology that the currently used natural gas pipeline printing mold is poor in usability and the text or pattern engraved on the printing mold cannot be changed, and to provide a mold for natural gas pipeline printing.

[0005] The utility model provides a mold for natural gas pipeline printing, comprising

[0006] A flexible magnetic plate for installation on the outer wall of a natural gas pipeline, the flexible magnetic plate having at least one through-mounted mounting slot, the mounting slot being provided with a flexible sign plate, the flexible sign plate being detachably connected to the mounting slot; the flexible sign plate having a first hollow portion; the flexible sign plate being capable of abutting against the outer wall of the natural gas pipeline;

[0008] The utility model discloses a mold for spray printing on a natural gas pipeline. The flexible magnetic plate can be pasted on the natural gas pipeline by means of a magnetic connection. The flexible magnetic plate can change its shape according to the curvature of the natural gas pipeline, so that the flexible magnetic plate can fit tightly with the natural gas pipeline; a plurality of installation slots are opened on the flexible magnetic plate, and a flexible sign plate is arranged in the installation slot. The flexible sign plate can be bent following the flexible magnetic plate, and a hollow portion for spray printing a pattern is arranged on the flexible sign plate; the flexible sign plate is detachably connected to the installation slot, so that the operator can replace the flexible sign plate with a different hollow portion shape in the installation slot according to the demand, so as to adapt to the spray printing of natural gas pipelines with different identification requirements; a first connecting piece and a second connecting piece are provided on the flexible magnetic plate, and when the flexible magnetic plate is attached to the outer wall of the natural gas pipeline, the first connecting piece and the second connecting piece are mutually connected to make the flexible magnetic plate firmly fixed on the natural gas pipeline, avoid displacement of the flexible magnetic plate, avoid offset of the spray printing pattern, and ensure the accuracy of the pattern sprayed on the natural gas pipeline.

[0009] A flexible magnetic plate is a plate-like structural member that can deform within a certain range. It has the properties of a magnet and can be adsorbed onto iron components. Common flexible magnetic plates are rubber plates doped with magnetic powder.

[0010] Preferably, the flexible magnetic plate is provided with a limiting groove, the limiting groove is communicated with the mounting groove, and the flexible sign plate is provided with a limiting member, and the limiting member can be adaptively connected with the limiting groove.

[0011] Through the coordinated connection of the limiting groove and the limiting piece, the flexible sign plate is difficult to fall off from the installation groove.

[0012] Preferably, the limiting member is a strip-shaped structural member, the two limiting members are respectively arranged on the two side edges of the flexible sign board, and the two limiting grooves are relatively arranged on the two sides of the installation groove.

[0019] The paint material passes through the first hollow part or the second hollow part, so that the pattern printed on the natural gas pipeline is the digital logo, text logo and symbol logo displayed by the first hollow part or the second hollow part.

[0020] The flexible magnetic plate is a rectangular plate, and a plurality of the mounting slots are arranged in an array.

[0021] The rectangular flexible magnetic plate is more convenient for position adjustment. By setting a number of installation slots, the flexible magnetic plate can be replaced with multiple patterns for printing.

[0023] The first connecting piece and the second connecting piece can fix the flexible magnetic plate tightly against the outer wall of the natural gas pipeline to prevent the flexible magnetic plate from shifting in position; by connecting multiple first connecting pieces and multiple second connecting pieces respectively, the fixing effect of the first connecting piece and the second connecting piece on the flexible magnetic plate is strengthened, making it difficult for the flexible magnetic plate to shift in position; by stretching the first connecting piece and the second connecting piece and then connecting them, the elastic force of the elastic piece makes the flexible magnetic plate fit tightly against the outer wall of the natural gas pipeline.

[0024] Preferably, a first connecting portion is provided at the end of the first connecting member, and a second connecting portion is provided at the end of the second connecting member, and the first connecting portion and the second connecting portion are detachably connected.

The positive Velcro and the reverse Velcro can realize quick connection between the first connecting part and the second connecting part; in some embodiments, the first connecting part and the second connecting part are connected by a snap buckle.

[0026] Preferably, the flexible magnetic plate is provided with a bubble level meter, and the bubble level meter is detachably connected to the flexible magnetic plate.

[0027] By setting up a horizontal bubble meter, the position of the flexible magnetic plate on the natural gas pipeline can be adjusted according to the horizontal bubble, avoiding the position displacement of the printed pattern on the natural gas pipeline; since the natural gas pipelines in the gas production station are all set horizontally or vertically, the holding groove is opened on the flexible magnetic plate in the length direction parallel to the natural gas pipeline, and the horizontal bubble meter is adapted to be set in the holding groove.
