Description

Technical Field

[0001] The present utility model relates to the technical field of gravure cylinder protection devices, and particularly to a gravure cylinder protection device convenient for dust removal. Background Technique

[0002] Gravure printing is abbreviated as "gravure". It is a plate-making technology in which images are engraved recessed on the surface. It first appeared in Europe in the 15th century. Hand-carved recessed graphics and texts were made on metal plates. During printing, ink was applied, and the ink on the plate surface was removed, leaving only the ink in the recessed part to be transferred to the paper. Later, photo-etching gravure (formerly called photogravure) and mechanical engraving gravure (including those engraved by electronic engraving machines), laser engraving gravure, electron beam engraving gravure, etc. were developed. To print a gravure plate, ink is applied to the surface, and then the ink is wiped off the surface with a Tarlatan cloth or newspaper, leaving only the recessed part. A wet paper is placed on the upper part of the plate, and the plate and the paper are pressed by a printing machine to transfer the ink from the recessed part of the plate to the paper.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4, this utility model provides a technical solution for a gravure roll protection device that facilitates dust removal: A gravure roll protection device that facilitates dust removal includes a base 1, a storage box 2, and a processing tank 3. A storage box 2 is installed above the base 1, and a processing tank 3 is provided inside the storage box 2. Squeezing plates 4 are provided on both sides inside the processing tank 3. A connecting rod 5 is installed on the right squeezing plate 4, and the connecting rod 5 is connected to the inner wall of the processing tank 3 through a rotating shaft 6. An automatic telescopic rod 7 is installed on the left side of the left squeezing plate 4. The automatic telescopic rod 7 is installed inside a fixed column, and the fixed column penetrates through the storage box 2 and is connected to a motor 8. The automatic telescopic rod 7 is connected to the motor 8 through a conductive slip ring. A cleaning device 9 is installed at the middle position inside the processing tank 3, and the upper part of the cleaning device 9 is installed above the storage box 2;

[0028] The cleaning device 9 includes a vacuum cleaner 901, a pipe body 902, and a telescopic pipe 903. A vacuum cleaner 901 is installed above the storage box 2. A pipe body 902 is installed below the vacuum cleaner 901. A telescopic pipe 903 is installed inside the pipe body 902. A sealing ring 904 is installed above the outer wall of the telescopic pipe 903. The lower part of the telescopic pipe 903 is installed at the middle position above the vacuum cleaner 901.

[0029] After the device fixes the gravure roll and rotates it, the user uses vacuum cleaners 901 of different lengths according to the length of the gravure roll, and fits the fixing pipe 913 with the connecting groove 911. The sealing gasket 912 is used to increase the sealing performance of the second fixing groove 906. The clamping groove 915 provided on one side of the vacuum cleaner 901 is clamped and fixed with the clamping block of the other side of the vacuum cleaner 901, so as to fix between multiple vacuum cleaners 901. Then, the rubber plug 916 is used to block the second fixing groove 906 and the connecting groove 911, making the length between multiple vacuum cleaners 901 the same as the length of the gravure roll, reducing the situation that the gravure roll is not cleaned, so that the brush 909 can clean the gravure roll of different lengths, improving the working quality of the device. Secondly, the automatic telescopic rod 910 is started to drive the vacuum cleaner 901 to slide. The vacuum cleaner 901 drives the telescopic pipe 903 to slide inside the pipe body 902, so that the brushes 909 installed on both sides below the vacuum cleaner 901 are in contact with the outer wall of the gravure roll. At the same time, the vacuum cleaner 901 is started, and the device drives the gravure roll to rotate, so that the brush 909 removes the dust inside the grooves on the outer wall of the gravure roll, and the dust is sucked into the second fixing groove 906 through the dust suction groove 907. Then, the dust passes through the first fixing groove 905, the telescopic pipe 903 to the inside of the sealing ring 904 through the second fixing groove 906, so that the vacuum cleaner 901 can clean the dust, making the dust removal work of the device better.

[0034] The telescopic pipe 903 and the sealing ring 904 are closely fitted, and the lower part of the telescopic pipe 903 is fixedly connected to the base 1.

[0035] The first fixing groove 905 is communicated with the inside of the telescopic pipe 903 and the inside of the second fixing groove 906, and the inside of the second fixing groove 906 is communicated with the inside of the dust suction groove 907.

[0036] The first fixing groove 905, the second fixing groove 906, the dust suction groove 907, and the connecting groove 911 are all integrally arranged with the vacuum cleaner 901, and the vacuum cleaner 901 and the sealing gasket 912 are closely fitted.

[0037] The connecting groove 911 and the fixed pipe 913 are correspondingly arranged, and the fixed pipe 913 and the vacuum cleaner 901 are fixedly connected.

[0038] The clamping groove 915 and the clamping block are in clamping connection, and the rubber block 914 is correspondingly arranged between the rubber plug 916 and the connecting groove 911.

[0039] Working principle:

[0040] First, when in use, the user places the gravure roll in the middle position between the two squeezing plates 4. Through the action of the conductive slip ring, the conductive slip ring starts the motor 8 to drive the automatic telescopic rod 7 to slide. The automatic telescopic rod 7 drives the left squeezing plate 4 to slide so as to clamp and fix gravure rolls of different models, increasing the applicability of the device. Secondly, start the motor 8 to drive the fixed column to rotate. The fixed column drives the automatic telescopic rod 7 to rotate.
