Abstract
The invention discloses a safety protection mechanism for a printing press. The safety protection mechanism for the printing press comprises an oscillating bar which is connected to an air cylinder. The air cylinder is fixed on a rack wallboard through an air cylinder fulcrum shaft and a small shaft. A connecting shaft is connected to a piston rod of the air cylinder. The connecting shaft is connected with one end of the oscillating bar through a screw. The other end of the oscillating bar is fastened on the rack wallboard through a fulcrum shaft. An idler wheel is installed at the upper right end of the oscillating bar. The idler wheel is fixedly assembled at the upper right end of the oscillating bar. A stop block and a gripper piece are connected together and assembled on a toothed shaft. The toothed shaft is mounted in a hole of a paper passing oscillating arm in a penetrating mode. The paper passing oscillating arm is fixed with a power shaft together and swings along with the power shaft. Meanwhile, the paper passing oscillating arm is arranged on the toothed shaft in a sleeved mode to make the toothed shaft swing. The safety protection mechanism for the printing press solves the performance problems of a large-format paper mutual interlocking gear, improves the safety and reliability of the printing press, improves printing efficiency, and reduces equipment faults of the printing press and waste of resources.
Description
Technical field:
The present invention relates to a kind of protection mechanism, be specially adapted to use when sheet-fed lithographic press positions every a piece of paper and detects.
Background technology:
Sheet-fed offset press in the course of the work, need to position every a piece of paper and detect, if detect paper to occur paper feed fault, during as the problem such as askew, empty, need to stop paper transmission in time, avoid tearing waste paper and rolling bad the problems such as blanket, final guarantee printing quality and device security.In actual printing work, because present paper breadth becomes large, when paper tail leaves tooth platform, the Photoelectric Detection time is very short, and when detecting that sheet positioning has problem, mutual interlocking gear does not have grace time to control feeding mechanism, first problematic paper is caused to process in time, can not meet instructions for use, finally equipment and printed matter are worked the mischief, bring very large loss to user.
Summary of the invention:
Task of the present invention proposes one to be unclamped by force by problematic for detection paper, stops a kind of printing machine safety protection mechanism transmitted to printing element.
Task of the present invention completes like this, a kind of printing machine safety protection mechanism, it comprises the fork that cylinder connects, it is characterized in that: cylinder is fixed on frame plate by cylinder fulcrum and little axle, the piston rod of cylinder is connected with connecting axle, connecting axle is connected with one end of fork by screw, the other end of fork is fastened on frame plate by fulcrum, at the upper right side of fork, roller is housed, roller is fixed and is assemblied in the upper right side of fork, block and gripper sheet link together and are assemblied on tooth axle, tooth axle is installed in the hole of transfer swing arm, transfer swing arm and line shaft are fixed together to swing with line shaft, transfer swing arm is simultaneously enclosed within tooth axle and makes tooth axle produce oscillating motion.
The present invention has following effect: the invention solves large format paper mutual interlocking gear performance disadvantage, improves the safety and reliability of printing machine, improves printing efficiency, reduces equipment fault and the wasting of resources.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention; Fig. 2 is side diagram of the present invention.
Drawing illustrates: 1, cylinder, 2, fork, 3, connecting axle, 4, block, 5, gripper sheet, 6, paper, 7, roller, 8, fulcrum, 9, transfer swing arm, 10, tooth axle, 11, line shaft, and 12 frame plates.
Detailed description of the invention:
The technical problem to be solved in the present invention is: for large format paper, it is more late that paper tail leaves tooth platform, when photoelectric detection mechanism detects page punt, paper is held in the month by the gripper sheet 5 in transfer swing arm 9, finally can not work the mischief to equipment and printed matter.The technical program is that cylinder 1 is fixed on frame plate 12 by cylinder fulcrum 8 and little axle, the piston rod of cylinder 1 is connected with connecting axle 3, connecting axle is connected by screw one end with fork 2, the other end of fork is fastened on frame plate by fulcrum 8, at the upper right side of fork, roller 7 is housed, roller is fixed and is assemblied in the upper right side of fork 2, block 4 and gripper sheet 5 link together and are assemblied on tooth axle 10, tooth axle 10 is installed in the hole of transfer swing arm 9, transfer swing arm and line shaft 11 are fixed together to swing with line shaft 11, transfer swing arm 9 is simultaneously enclosed within tooth axle 10 and makes tooth axle 10 produce oscillating motion.
During work, when Photoelectric Detection finds that there is paper feed problem, ventilate in electrical system control cylinder 1 lower end, piston rod drives connecting axle 3 motion to make fork 2 around fulcrum 8 clockwise oscillation, roller 7 upwards pushes block 4, block 4 and gripper sheet 5 link together, paper 6 just can not be held in the month by gripper sheet 5, when transfer swing arm 9 is to lower swing, paper 6 would not move together along with transfer swing arm 9, problematic paper will rest on original position, printing element can not be entered, would not occur like this tearing waste paper or problematic paper being delivered to printing element, cause damage or the damage parts of blanket.When sheet positioning is no problem, roller 7 moves downward, and retains certain interval with block 4, and gripper sheet 5 just can normally to send in opening and closing and transfer, thus ensures normal printing.
