Set type flexible printing machine printing unit
Technical field
The present invention relates to a kind of set type flexible printing machine, be specifically related to a kind of printing unit of set type flexible printing machine.
Background technology
Set type flexible printing machine has the advantages such as machine construction is simple, adaptability for materials is strong, force of impression is little, printing cost is low, the fast quality of print speed printing speed is good, environmental protection.Printing unit is the core of set type flexible printing machine, printing unit comprises roller, bottom roller and net roller, its ideal operation state should be: roller will be changed conveniently, roller and bottom roller, squeegee pressure between roller and net roller all want suitable and stable, quick adjustment can be realized, and roller work time axial location adjustable with satisfied convenience to version, so just can increase work efficiency and promote printing quality.But the printing unit of prior art is but difficult to accomplish, if the patent No. 201420513747.2, patent name " flexible printing machine printing pressure regulating device " are although the patented technology that provides solves the adjustment problem of squeegee pressure between roller and bottom roller, net roller, but obviously can not realize quick adjustment, roller only does moving up and down of vertical direction simultaneously, there is strict demand to the diameter of bottom roller, net roller and setting height(from bottom), generally need bottom roller, the diameter of net roller, setting height(from bottom) the same, patent No. 201120476838.X in addition, patent name " a kind of single servo gearless type flexographic printing unit " is although to solve roller axial location adjustable to facilitate version for the patented technology that provides, roller upper-lower position is adjustable with the technical problem of squeegee pressure between adjustment and bottom roller, but it is the same with the patented technology of the patent No. 201420513747.2 and the printing unit of other all prior art, the up and down of roller all could will be realized (namely roller only does moving up and down of vertical direction in adjustment process) by motor-driven bolt and nut, but the squeegee pressure between this structure roller and net roller regulates and just has problems, just as the patent of the patent No. 201420513747.2 background technology described in.
Summary of the invention
In view of the deficiencies in the prior art, the object of the invention is to be to provide the position of a kind of axial, left and right of roller and above-below direction adjustable, quick plate change can be realized, version is regulated and the adjustment of squeegee pressure, increase work efficiency and promote the set type flexible printing machine printing unit of printing quality.
The present invention takes following technical scheme:
Set type flexible printing machine printing unit, comprise the roller be arranged between the frame plate of front and back, bottom roller and net roller, roller is positioned at top, bottom roller is positioned at the lower right side of roller, net roller is positioned at the lower left side of roller, it is characterized in that: the rear axle head of roller carries out pivoting support by bearing block and is connected with roller motor-driven, bearing block and roller motor are fixedly mounted on the first support, first support connects the floating action making left and right directions freely on the secondary support bracket, second support is connected to the sliding action the 3rd support being made fore-and-aft direction and drives by regulating motor, motor is regulated to be fixedly mounted on the 3rd support, above-below direction made by 3rd support sliding action at the back side of afer bay wallboard is promoted by the first cylinder, the shaft shoulder of roller during printing work before and after it is rested the head on by the dancer of semicircular ring shape and is carried out supporting then being compressed by hook plate, the up and down of hook plate is promoted by the second cylinder, roller pillow is located at the inner side of frame plate, the below of roller pillow is provided with left and right support arm, left and right support arm is provided with corner circular arc pair roller pillow and supports, corner center of arc and the Wang Gun center of left support arm are concentric, corner center of arc and the bottom roller center of right support arm are concentric, left and right support arm swings to arrange and is promoted by left and right support arm cylinder, swing pivot is positioned at support arm upper end, the outside swing of left and right support arm is undertaken spacing by left and right limited block, limited block adjustable setting in left and right is connected with left and right minor adjustment motor.
After adopting technique scheme, course of action of the present invention is: roller is when upper limit position, the front axle head of roller hangs outward, conveniently can carry out plate change operation, after plate change completes, roller is promoted downward fast by the first cylinder, due to roller free floating in the lateral direction, rest the head on and fall into roller and rest the head on self-centering so the shaft shoulder of roller downwards can aim at dancer (roller does not do proper vertically movement up and down, thus it is large to adapt to bottom roller diameter, the different actual design of the little and setting height(from bottom) of net roller diameter requires), the lower half circle of the roller shaft shoulder is rested the head on by roller and is supported, because roller pillow supported by left and right support arm, so roller and bottom roller, certain clearance distance is all left between net roller, then promote the downward action of hook plate by the second cylinder to compress from roller shaft shoulder top roller, then, the bottom that left and right support arm cylinder promotes left and right support arm outwards swings, thus make the corner circular arc of left and right support arm, roller pillow and roller entirety move down, roller and bottom roller, roller and net roller realize contacting, because the outside swing position of left and right support arm is undertaken spacing by left and right limited block, and the position of left and right limited block is regulated by left and right minor adjustment motor, so roller and bottom roller, the contact (i.e. squeegee pressure) of roller and net roller can realize regulating respectively and being independent of each other, guarantee roller and bottom roller, squeegee pressure between net roller is all suitable and stable, promote printing quality, and realize quick adjustment, during printing work, carry out the movement of axial location to realize fast regulating version by adjustment driven by motor roller.After adopting technique scheme, due to axial, the left and right of roller and the position of above-below direction adjustable, particularly the free floating of left and right directions regulates, and dancer pillow, left and right support arm, support arm cylinder and left and right minor adjustment motor setting, so quick plate change can be realized, regulate and the automatic adjustment of squeegee pressure version, thus increase work efficiency and promote printing quality.In addition, in technique scheme, roller pillow is free floating setting, not only good supporting role is played to roller during work, the position in the lateral direction, roller center of the different size diameter of automatic adaptation is departed from, and can change together with roller when changing plate, and need not carry out unnecessary design in roller shaft shoulder size, make structure simple, be also more suitable for need of work.
As preferably, the lower end of described hook plate is articulated and connected in vertical push pedal, and vertical push pedal slides up and down the inner side being located at frame plate, and the bottom of vertical push pedal is connected with the second cylinder, vertical push pedal is also provided with the 3rd cylinder, the 3rd cylinder promotes hook plate and makes rotary movement.After adopting above-mentioned design, hook plate also can carry out rotary movement while making knee-action, at utmost conveniently to meet needed for work.
As preferably, the roll shaft two ends of described net roller are rested the head on to carry out supporting by half opening roller and are then compressed by semi-ring block, and the up and down setting of semi-ring block is promoted by four-cylinder.After adopting above-mentioned design, net roller can realize quick despatch, to facilitate cleaning.
