Description
Предлагаемое устройство дл осевого перемещени ракельного ножа машин глубокой печати просто к вместе с тем обеспечивает различное положение ракельного ножа после каждого его осевого перемещени , что вл етс основным требованием к механизму привода ракельного ножа.The proposed device for the axial movement of the doctor blade of the intaglio printing machine simply at the same time provides a different position of the doctor blade after each axial movement of it, which is a basic requirement for the drive mechanism of the doctor blade.
Устройство выполнено в виде двух сцепленных О1естерен, имеющих различное количество зубцов и снабженных кривошипами, соединенными посредством шатунов с т гой ракельного ножа.The device is made in the form of two coupled O1esteren, having a different number of teeth and equipped with cranks connected by means of connecting rods with a squeegee blade.
Кривошипы дл изменени их радиуса установлены на шестерн х с возможностью радиального перемеП1 ,ени .The cranks for changing their radius are mounted on gears with the possibility of radial interchange 1.
На чертеже изображена схема устройства.The drawing shows a diagram of the device.
Устройство представл ет собой две сцепленные между собою шестерни 1 и 2. Шестерн / вл етс приводной. Обе. :UjecTepHH имеют кривошипы 3, которые шатунами 4 св заны с т гой 5 ракельного .ножа. The device consists of two interlocking gears 1 and 2. The gear / is driven. Both. : UjecTepHH have cranks 3, which are connected with connecting rods 4 with a thrust of 5 squeegees.
При вращении uiecrepeH J п 2 ракельный нож получает возвратнопоступательное дв :жение.When you rotate uiecrepeH J p 2, the doctor blade receives a reciprocating two-piece: live.
Дл того чтобы перемещени ракельного ножа по длине были разнообразны , числа зубьев шестерен выбирают возможно больптими и взаимно просты.ми. Например, при числе зубьев 59 и 60 траектори первого оборота по вл етс только после 59 оборотов большей шестерни .In order to vary the length of the doctor blade, the numbers of gear teeth can be chosen as large and mutually simple. For example, with the number of teeth 59 and 60, the trajectory of the first revolution appears only after 59 revolutions of the larger gear.
Дл изменени радиусов кривошипов они монтированы на шестерн х с возможностью их радиального перемещени , причем радиус одногоиз кривошипов беретс большим, от чего зависит величина перемешени ножа. Радиус другого кривошипа беретс небольшим, с только изменени движени ножа с каждым оборотом кривошипа. Изменением радиуса этого кривошипа ре .гулируетс характер изменени движени ножа.To change the radii of the cranks, they are mounted on gears with the possibility of their radial movement, and the radius of one of the cranks is taken to be large, which determines the amount of knife shuffle. The radius of the other crank is small, with only a change in the movement of the knife with each turn of the crank. By changing the radius of this crank, the nature of the change in movement of the knife is adjusted.
В процессе работы устройства устран етс срабатывание определенных точек лезви .ракельного ножа ввиду периодического взаимодействи этих точекс однимии теми же точками -печатной формы машин.During the operation of the device, the operation of certain points of the blade of the knife is eliminated due to the periodic interaction of these points with the same points of the printing form of the machines.
