It is equipped with the card slot.
The technical program has the advantages that：
Knife cavity shell and first gasket at knife cavity shell both ends, and knife cavity shell form a closed loop sealing, ink
A closed circulation is automatically formed during disengaging, the ink for being sticked to anilox roll both ends is shaved by the second gasket, knife cavity shell both ends
Dual-seal is used at the sealing cover of end, the axis of the vertical anilox roll of the first gasket, the second gasket is set, so that
Anilox roll both ends of the surface form right-angle type sealing, it is ensured that ink will not be deposited in reticulate pattern roller surface.A circle O-ring is set at side cover again
Sealing.The ink or liquid inside oozed can be sealed without being thrown out of or water clock because of the circle at anilox roll both ends.The utility model solves
The black problem of anilox roll circumferential surface product, effectively increases work efficiency and printing quality, improves working environment and labor intensity.

Embodiment
It is further described with reference to 1 to 8 pair of the utility model of embodiment and attached drawing.
A kind of closed scraper, including anilox roll 4, knife cavity shell 5, scraper 7, scraper pressing plate 8, end sealing cover 6, first are close
Packing 1, the second gasket 2, the knife cavity shell 5 are arranged on the side of the anilox roll 4, and one end of the scraper 7, which is fixed, to be set
Put on the knife cavity shell 5, the other end of the scraper 7 is abutted with the anilox roll 4, unnecessary in anilox roll 4 for scraping
Ink.The scraper pressing plate 8 is fixedly connected positioned at the top of scraper 7 with the knife cavity shell 5.The scraper 7, knife chamber shell
A hollow cavity is formed between body 5, anilox roll 4, second gasket 2, the first gasket 1, end sealing cover 6 are set gradually
In 5 end of knife cavity shell.First gasket 1, the second gasket 2 are vertical with the axis of the anilox roll 4.It is described
First gasket 1 is fitted on the surface circle of the anilox roll 4, and second gasket 2 is fitted in the end face of the anilox roll 4
On circle.
The end sealing cover 6 is located at the end of the knife cavity shell 5, and is fixedly connected with the knife cavity shell 5.The knife
The section of cavity shell 5 is U-shaped, and the both ends of the knife cavity shell 5 are both provided with the card slot 9.First gasket 1 is located at institute
State in card slot 9, be closely connected with the anilox roll 4, and be tightly connected with the knife cavity shell 5.Opened up on the end sealing cover 6
There is holding tank 11, second gasket 2 is located in the holding tank 11.Second gasket 2 is located at the end sealing cover 6
Between first gasket 1, be close to first gasket 1, be closely connected with the anilox roll 4, and with the knife chamber
Housing 5 is tightly connected.The width of the holding tank 11 is more than the width of second gasket 2, so that the second gasket 2 is firm
Admittedly be fixed on anilox roll 4 and end sealing cover 6 between.The end of the knife cavity shell 5 offers seal groove 10, the seal groove
10 structure is U-shaped.Sealing ring 3 is provided with the seal groove 10, the both ends of the sealing ring 3 are abutted to the scraper pressing plate
6。
