Description
Technical field
The utility model relates to a kind of offset press blanket cylinder surface automatic descaling apparatus, refers to a kind of being used in the offset printing especially, the isolated plant of in offset press high speed printing process the dirt on blanket cylinder surface being removed automatically with scraper.
Background technology
At present, in offset printing, need blanket cylinder with the transfer printing of the printing ink on forme elder generation on, and then by blanket cylinder printing ink is transferred to and forms picture and text above the paper.If there is dirt in the blanket cylinder surface, dirt will be blocked the transfer of printing ink, makes on the paper part that should form picture and text in should the zone not have picture and text, promptly produces " white point " defective on product.When finding " white point ", comparatively the way of standard is a shutdown inspection, the dirt that manual removal blanket cylinder surface exists; Nonstandard way is a shutdown inspection not, is directly still taking out stains on the blanket cylinder surface of rotation at a high speed by hand.
If shut down the manual cylinder dirt that strikes off; need offset press progressively to accelerate to normal engine speed from zero again again to zero from the fast state reduction of speed; readjust the mass colour that the China ink amount reaches product needed that adds of each ink fountain; this adjustment process is short then 3-5 minute; long then a few hours are not waited; look the influence of workman's technical merit, the quality of paper, the quality of printing ink and the performance of machine or the like factor, during the product produced be difficult to reach the requirement of regulation.The normal engine speed of modern offset press is all more than 10000/hour, shuts down output and quality to unit at every turn, all can produce adverse influence to whole production rhythm.
Therefore; concrete board operating personnel often adopt nonstandard way, and shutdown inspection does not directly take out stains on the blanket cylinder surface of rotation at a high speed by hand; doing like this needs operating personnel itself to have comparatively superb operation skill, need emit sizable Personal Risk.Careless slightly, even the blanket cylinder that veteran operating personnel also may be rotated at a high speed will be pointed even entire arms is brought the machine the inside into, therefore situation about disabling happens occasionally.
Generally speaking, these dirts that are deposited in the blanket cylinder surface mainly are made up of the paper hair.Paper surface usually is attached with impurity such as a small amount of paper hair, and installation electrostatic adsorption device or vacuum absorption device can be removed a spot of paper impurity near the paper feed cylinder, but still can produce dirt on the blanket cylinder surface frequently.If paper quality is too poor, paper surface adheres to impurity such as a large amount of paper hairs, and near the adsorbent equipment of installing the paper feed cylinder will have little time to remove, and causes a large amount of, regular generation dirts on the blanket cylinder surface, and offset printing production is produced very adverse influence.
Summary of the invention
In order to overcome above-mentioned weak point, main purpose of the present utility model aims to provide a kind of scavenge unit, by control system with comprise near the scraper that can blanket cylinder, freely carry out one dimension, two dimension even three-dimensional rapid movement, a kind of offset press blanket cylinder surface automatic descaling apparatus that when offset press normally prints, can remove the dirt on blanket cylinder surface.
The technical problems to be solved in the utility model is: how near the scraper that solve blanket cylinder freely carries out one dimension, two dimension even three-dimensional rapid movement problem, solve how simple position coordinate definite to the position of " white point " on the product and blanket cylinder surface dirt is determined, solve how this coordinate to be input in the control system by touch-screen; How control system guides this scraper with one dimension, two dimension even three-dimensional rapid movement ability that the dirt on the blanket cylinder such as is removed at the relevant technologies problem automatically.
The technical scheme that its technical problem that solves the utility model adopts is: this device comprises blanket cylinder, scraper, motor, encoder and control system, described blanket cylinder is provided with rotary encoder blanket cylinder motion angle signal is provided, scraper with three-dimensional motion ability is installed near blanket cylinder, described scraper is fixed on rotating scraping on the tool rest, scraping tool rest is located on the fixed head, fixed head is installed on the linear electric motors, one platform that is provided with linear electric motors is installed on the slide block of Rodless cylinder, and the wallboard of both sides is fixed at the Rodless cylinder two ends.
The scraper of described a kind of offset press blanket cylinder surface automatic descaling apparatus is the thin slice that metal or nonmetallic materials are made.
Described Rodless cylinder is that stroke is longer than blanket cylinder and is provided scraper to make the cylinder of transverse movement; Described linear electric motors are the vertical motors that provide scraper to travel longitudinally of installing; Control system control scraper and of short duration accurate contact the in dirt position of rotating the blanket cylinder surface are scraped dirt.
The scraper of described a kind of offset press blanket cylinder surface automatic descaling apparatus is the air knife that the gases at high pressure that discharge in the controllable nozzles form.
The beneficial effects of the utility model are: by control system with comprise near the scraper that can freely carry out one dimension, two dimension even three-dimensional rapid movement blanket cylinder, when offset press normally prints, can remove the dirt on blanket cylinder surface, have the location accurate, simple to operate, safe and reliable, easy to use, advantage such as raise the efficiency.
