Description
Technical field
The present invention relates to a kind of fast automatic pair of bar pulling mechanism of paper for offset printing press.
Background technology
Offset printing press is a kind of indirect printing principle of using, ink and water adhere to the forme face that is rolled in plate cylinder cylindrical by ink rubber roll balanced system, engaged with plate cylinder by blanket cylinder and clip stationery stock and roll, the picture and text on required forme are transferred to the machine printing on the stocks such as business card, drop, postcard, various cards.Main body, paper advance mechanism, pulling mechanism of paper, drive and control of electric machine unit that offset printing press is made up of cylinder, rubber roll, side plate and base plate form.Paper card (being called for short paper below) as stock is stacked on the pile board of paper advance mechanism, by vacuum paper-absorbing dish, a sheet by a sheet paper picking up is put into paper feeding platform rear end, by pulling mechanism of paper by the engagement place of a sheet by a sheet paper of rear end two cylinders of shifting front end onto, the engagement rolling of two cylinders is involved in paper and prints, per hour the reaching ten thousand times of speed that paper feeding is round, send to the paper of front end and the relative position of cylinder and just determined the position of printing picture and character on paper, so send the paper feeding accuracy rate of pulling mechanism of paper directly to have influence on the accuracy of the rectifying of printing product, visibility and chromatography.
The pulling mechanism of paper that offset printing press uses at present has: 1, use and angle paper cam to rotate, block, fork just move once to a withdrawing position separating with it from an extrusion position on paper-feeding passage, thereby a piece of paper is sent to paper feed roller; 2, feeding-in roll, comprises roll body, is connected with paper feeding rubber roll on it, it is characterized in that the two ends of roll body are by bearings, and one end of roll body is connected with roll body tolerance clearance control apparatus double adhesive tape rolling paper feeding.These mechanisms exist can only short range transmission, the easily defect of wearing and tearing of roll body, and double adhesive tape roll can not precise synchronization, paper feeding can not accurately put in place, causes register trouble true.
Summary of the invention
The present invention seeks to: a kind of fast automatic pair of bar pulling mechanism of paper for offset printing press is provided, can fast speed automatically paper be delivered to accurate printing position, guarantee that printing is proper, clear, chromatography is accurate, easy to operate, noiselessness long service life.
Technical scheme of the present invention is: a kind of fast automatic pair of bar pulling mechanism of paper for offset printing press is provided with and pushes away paper parts, pedestal, guide rail, power part and photoelectric control components composition.Described pedestal for parts that two automatic pulling mechanism of paper of bar are installed be connected with body, guide rails assembling, on pedestal, pushes away paper parts and is connected with slide block; Connecting panel by power part with push away paper parts and be connected.
The described paper parts that push away comprise: adapter plate, two eccentric pushing posts, saddle type spring shim, two push away post fixed block, axle fixed block, axle, back-up ring, two flanged bearings, keep electromagnet.Concrete mounting structure between part is: eccentric pushing post with push away post fixed block riveted joint, between two contact surfaces, wear a saddle type spring shim, two push away post fixed block is locked on axle, the small column of axle fixed block bottom connects electromagnet slide core, upper hole is through on axle and is screwed, two ends of axle are equipped with flanged bearing, and flanged bearing and adapter plate biend hole are fixed, and cause the axle can only radial rotating under the drive of electromagnet and can not rock up and down.
Sequence of operation is: when paper is put into paper feeding platform rear end, the maintenance electromagnetic core pushing away on paper parts at two bars at paper rear moves forward, the post fixed block that pushes away on the axle fixed block band moving axis being associated turns to upper surface on axially and is level attitude, be arranged on the eccentric pushing post that pushes away on post fixed block thereupon upwards, upper surface just exceeds the upper plane that is pushed away paper, the leading flank of the two eccentric pushing posts that modulate is in advance same level line, drive and push away paper parts first to promote paper parallel by power part, subsequently along guide rail forward until paper feeding platform front end specified point, power part is out of service, keep electromagnetic core to move backward, pushing away post fixed block rotates around axle, eccentric pushing post upper surface is just lower than the lower plane that is pushed away paper, power part moves backward, drive pushes away paper assembly and returns to and push away paper platform and place the rear for the treatment of paper feeding, complete and once push away paper program.
Advantage of the present invention is:
1, push away the operation of paper parts, adopt the ball of slide block and the line slideway mode that closely cooperates, can reach quick, low wearing and tearing, noiselessness, high precision and move.
2, eccentric pushing post is provided with upper and lower eccentric cylinder, and the convenient front and back gap that regulates two eccentric pushing posts guarantees to push away the parallelism on the paper face of cylinder, and the groove adjustment means easy to use of upper surface pushes away groove two limits, paper post upper surface and divides high bottom surface to reduce to push away the amplitude that post rotates.
3, be provided with the post fixed block that pushes away that clamps elastic groove and facilitate adjusting angle, reliably fixing.
4, adopt and keep electromagnet to be equipped with that U-shaped connecting block structure reaches fast, stablizes, high-frequency is movable.
