Description

High and be convenient for to clear up of factor of safety double faced offset press

Technical Field

The utility model belongs to the technical field of the lithography apparatus technique and specifically relates to a high and be convenient for clear up run from opposite directions double-sided offset press of factor of safety.

Background

An offset printing press is a kind of offset printing press, in which printing images are first printed on a blanket cylinder from a printing plate and then transferred to paper by the blanket cylinder. Offset presses can be divided into sheet-fed offset presses and web-fed offset presses according to different paper feeding modes; the printing color number completed by one-time paper feeding can be divided into single-color, double-color, four-color and multi-color printing machines; the full-paper printing machine can be divided into a small offset press, a six-opening, four-opening, two-opening and full-paper printing machine according to the maximum paper breadth to be printed, and a double-sided printing machine capable of simultaneously finishing two-sided printing by one-time paper feeding is also arranged. The single-sheet offset press is a lithographic printing press, is used for printing high-grade commercial printed matters and packaging printed matters, and is the mainstream of modern paper printing; the split double-sided offset press can print two sides at one time, and is very convenient.

The Chinese patent with the publication number of CN204367540U discloses a large folio double-sided thin paper offset press, which consists of a paper feeder, a paper feeding anti-static device, an ultrasonic double-sheet controller, a first color group on the back surface, a first transmission roller, a second transmission roller, a back impression roller, a thin paper high-precision zero-clearance cross-connection paper gripper mechanism, a middle transmission roller I and a middle transmission roller II, a second color group on the front surface, a paper collection air pressing device, a paper collection anti-static device, a paper collection part, a zero-backlash gear transmission mechanism and the like, wherein the paper feeder is provided with the paper feeding anti-static device; an ultrasonic double-sheet controller is arranged on the first color set on the reverse side; the paper conveying antistatic device ensures the smooth paper conveying of the thin paper; an ultrasonic double-sheet controller is arranged to effectively control the output paper; a thin paper high-precision gapless handing-over gripper mechanism is adopted, so that the handing-over of the paper is accurate; the paper collecting and antistatic device is arranged, so that the problem of neatness of ultrathin paper is solved; the paper collecting and air pressing device is arranged to enable the paper to be collected and placed orderly; the whole operation is stable by adopting the transmission of the backlash-free gear.

However, the utility model has the disadvantages that the rolling pillow is full of ink and dry dirt of glue water during long-term use, and needs to be cleaned regularly by operators, and the manual cleaning needs to be carried out by stretching a handle into a crack to clean and scrape the rolling pillow, so that if the offset press is started by misoperation, personal injury is easily caused; after the roller is printed, if other products are printed, the ink on the surface of the roller needs to be cleaned, and the cleaning is generally carried out manually, so that the labor intensity is high, and the cleaning is inconvenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high and be convenient for clear up of factor of safety's run from opposite directions double-sided offset press has the printing ink on convenient clearance cylinder surface and the advantage that improves factor of safety when clearing up printing ink and the dry dirt of glue on the pillow.

The above object of the present invention can be achieved by the following technical solutions:

the utility model provides a high and be convenient for clear up run from opposite directions double offset press of factor of safety, includes the organism, rotates the cylinder that sets up on the organism, it is provided with the pillow of rolling to lie in the cylinder both sides on the organism, it all is provided with the vertical montant that upwards extends to lie in the cylinder both sides on the organism, two just lie in between the montant and be provided with the horizontal rail unanimous with cylinder length direction directly over the cylinder, the removal is provided with the body of rod of vertical downwardly extending on the horizontal rail, be provided with the drive assembly who is used for driving body of rod reciprocating motion on the horizontal rail, the scalable setting of the body of rod, the tip of the body of rod is provided with the clearance subassembly that is used for clearing up the cylinder, it is provided with branch to lie in pillow one side of rolling.

According to the technical scheme, the length of the rod body is adjusted firstly, so that the cleaning assembly is in contact with the upper surface of the roller, then the driving assembly is started, the rod body moves along the length direction of the transverse rail, the cleaning assembly cleans the surface of the roller, and the offset press is started along the belt to rotate the roller, so that the cleaning effect of the cleaning assembly is better; and when the dry dirt of printing ink and glue on the pillow is rolled in the clearance, conflict on rolling the pillow to the shovel piece on the branch, it rotates to let cylinder pivoted drive the pillow of rolling simultaneously, the unmovable shovel piece just can arrive the whole scraping shovel of circumference that rolls the pillow this moment, thereby will roll pillow surface adnexed printing ink and the dry dirt scraping shovel of glue and fall, no longer need the manual work to clear up the cylinder after setting up like this, thereby reach the effect of convenient clearance cylinder, and when the pillow is rolled in the clearance, also no longer need artifical manual handle stretch into the crack to remove and scrape the pillow of rolling, thereby danger coefficient when also having reduced the clearance pillow of rolling.

Further, the cleaning assembly comprises a bottom plate, arc-shaped scraping blades and a cleaning brush, the bottom plate is located at the end of the rod body and is just opposite to the upper surface of the roller, the arc-shaped scraping blades are arranged in the middle of the bottom plate, and the cleaning brush is arranged on the bottom plate and located on two sides of each arc-shaped scraping blade.

Implement above-mentioned technical scheme, the body of rod is when taking the length direction removal of bottom plate along the horizontal rail, and the cylinder surface just can be scrubbed to the clearance brush of bottom plate both sides to let along with the rotation of cylinder scrub more fully, and the arc doctor-bar in the middle of the bottom plate just can be along with the rotation of cylinder and the removal of self carry out the spatula to the cylinder surface, and the cooperation of clearance brush and arc doctor-bar can make the cylinder surface more thoroughly rinsed.

Furthermore, a dovetail groove is formed in the bottom plate, the cleaning brush comprises a brush rod and brush bristles arranged on the brush rod, and the brush rod is in a dovetail shape and matched with the dovetail groove.

When the technical scheme is implemented, the brush rod is aligned to the opening end of the dovetail groove and inserted when the cleaning brush is installed, and the brush rod cannot be separated from the bottom plate in the vertical direction after being inserted into the dovetail groove due to the shape characteristic of the dovetail groove; when the cleaning brush needs to be detached from the bottom plate for cleaning, the brush rod directly slides out along the length direction of the dovetail groove, so that the effect of convenience in detaching and installing the cleaning brush is achieved.
