Description

Technical Field

[0001] The utility model relates to the field of dust covers for gravure printing machines, in particular to a dust cover for gravure printing machines. Background Art

[0002] A gravure printing press uses an intaglio plate for printing. The image and text on the plate are recessed, while the blank area is flush with the outer circumference of the plate cylinder. Existing large industrial gravure printing presses have multiple control stations for printing and conveying, spaced apart. These stations are separated by transparent slots that allow dust to easily enter the gravure press, affecting its proper operation.

[0003] The Chinese utility model with announcement number CN220865010U discloses a dust cover for a gravure printing machine, including an assembly strip, which is arranged horizontally, and a plurality of dust strips in contact with each other are provided on the lower end surface of the assembly strip from left to right, and a mounting hole is provided on the front edge of the assembly strip. Metal sleeves are provided on the outer sides of the bottom of the dust strips located on the leftmost and rightmost sides, and a dust cover structure specially used for the station slot of the gravure printing machine is adopted to effectively prevent dust from entering. During installation, bolts are fitted into the mounting holes to fix the assembly strip on the top of the station slot. At this time, the plurality of dust strips cover the station slot, and then the external threaded connector is screwed on both sides of the inner wall of the bottom of the station slot. When the magnetic block and the metal sleeve are attracted, the magnetic patches between the assembly strips are attracted at the same time, so that the plurality of dust strips are restricted in positioning to prevent shaking. When it is necessary to enter the station slot to observe the printing work, the dust strips can be directly opened.

[0004] There may be a gap between the assembly strip of the existing gravure printing machine dust cover and the outer surface of the gravure printing machine. Dust may flow into the interior of the printing machine with the air, which may have a serious impact on the printing quality and cause defects in the printed products, such as ink spots, scratches, and uneven colors. Therefore, there is a problem of poor sealing between the dust cover and the gravure printing machine. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , which is the first embodiment of the utility model, provides a dust cover for a gravure printing machine, including a protective cover 1, an outer surface of the protective cover 1 is fixedly connected to a mounting mechanism 2, an outer surface of the mounting mechanism 2 is adhered to a disassembly mechanism 3, the mounting mechanism 2 includes a plastic frame 204 fixedly connected to the outer surface of the protective cover 1, a lower surface of the plastic frame 204 is adhered to a mounting frame 202, and an outer surface of the mounting frame 202 is fixedly connected to a plurality of mounting blocks 201.

[0032] The specific mounting block 201 is fixedly installed on the side surface of the mounting frame 202, and a threaded hole is provided on the outer surface of the mounting block 201. The inner wall of the mounting frame 202 is fixedly connected with a first magnetic block 205. The upper surface of the first magnetic block 205 is fitted with the lower surface of the protective cover 1. The side surface of the plastic frame 204 is fitted with the inner surface of the mounting frame 202. The lower surface of the mounting frame 202 is fixedly connected with a sealing gasket 203.

[0033] Furthermore, bolts are used to fix the mounting block 201 in the reserved hole of the printer, so that the outer surface of the sealing gasket 203 fits tightly with the outer surface of the printer, thereby preventing dust from penetrating through the gap between the mounting frame 202 and the printer.

[0034] Example 2

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The disassembly mechanism 3 includes a second magnetic block 302 attached to the upper surface of the plastic frame 204, and the upper surface of the second magnetic block 302 is fixedly connected to the limiting plate 301.

[0036] Specifically, the lower surface of the second magnetic block 302 and the upper surface of the first magnetic block 205 attract each other. The disassembly mechanism 3 also includes a groove 303 opened on the outer surface of the installation frame 202, and the groove 303 is set at the four corners of the upper surface of the installation frame 202.

[0037] Furthermore, a corner of the limiting plate 301 can be lifted through the groove 303 to facilitate releasing the limiting of the protective cover 1, and then the plastic frame 204 can be pulled to facilitate disassembly of the protective cover 1, thereby facilitating cleaning and replacement of the protective cover 1.

[0038] It should be noted that the plastic frame 204, the limiting plate 301 and the mounting frame 202 are usually made of thermoplastic materials, and their shapes can be easily changed by applying external force after heating. This allows the dust cover to be flexibly shaped according to different usage requirements, so that it can be bent as required.

[0039] Working principle: By using bolts to fix the mounting block 201 in the reserved hole of the printing press, the outer surface of the sealing gasket 203 is tightly fitted with the outer surface of the printing press, thereby preventing dust from penetrating through the gap between the mounting frame 202 and the printing press. Through the groove 303, a corner of the limiting plate 301 can be lifted to release the limit on the protective cover 1. Then, the plastic frame 204 can be pulled to facilitate the removal of the protective cover 1, thereby facilitating the cleaning and replacement of the protective cover 1. It should be noted that in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
