Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 2-5, a kind of letterpress, including rack 1, bearing 1, impression cylinder 3, bearing 24 and rubber
Roller 5, the nearly rack 1 of the rolling pillow of impression cylinder 3 offer radiating groove 301 on one side, and the depth of radiating groove 301 is impression cylinder 3
The half for rolling pillow guarantees that the effect of heat dissipation, the quantity of radiating groove 301 are two, and two radiating grooves 301 are close in impression cylinder 3
The efficiency of heat dissipation is improved, the inside of radiating groove 301 is fixedly installed with cooling mechanism 6, is used in distribution with one heart in the side of rack 1
The heat that impression cylinder 3 rolls at pillow is exported rapidly, cooling mechanism 6 is made of heat-dissipating pipe 601 and fin 602, heat-dissipating pipe
601 and the material of fin 602 be the preferable copper alloy tube of heating conduction and plate, the outer diameter and radiating groove 301 of heat-dissipating pipe 601
Depth of section it is identical, enable heat derives of the heat-dissipating pipe 601 effectively by impression cylinder 3, while guaranteeing consolidating for heat-dissipating pipe 601
Fixed and heat dissipation effect, the cross sectional shape of fin 602 are rectangle, and the right side of fin 602 and the left outer surface of heat-dissipating pipe 601 are solid
The effect for increasing 601 surface area of heat-dissipating pipe to improve rate of heat dispation, the fixed peace in the bottom of 1 right side of rack are realized in fixed connection
Equipped with scraping block 7, the cross sectional shape of scraping block 7 is the quadrangle that adjacent both sides are curve, and the direction and coining of 7 liang of curved surfaces of scraping block roll
The rotation direction of cylinder 3 is opposite, and the top surface of scraping block 7 is bonded with the bottom that impression cylinder 3 rolls pillow outer surface, guarantees to work as impression cylinder 3
When rotation relative to scraping block 7, scraping block 7 can be rolled impression cylinder 3 under the slice on pillow, the material of scraping block 7 be quality compared with
Hard rubber block is guaranteeing to realize that the surface for protecting impression cylinder 3 to roll pillow while rooting out ink does not generate abrasion, thus
Guarantee the service life of printing machine, the left side of scraping block 7 is the cambered surface of indent, when ink is accumulated in the top left side of scraping block 7
