Background

A printer is a machine that prints text and images. Modern printing presses generally consist of mechanisms for plate loading, inking, stamping, paper feeding and folding. The working principle is that the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the place with characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred onto paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to copy the printed matter identical to original manuscript. Wherein paper feed mechanism is the vital part of printing machine, also be the mechanism of carrying out printing machine basis function, the paper feed mechanism reaction of current printing machine is slower, efficiency is lower, can't make discernment so that in time suggestion when printing machine deposit paper is not enough, and most crucial all need people to go to stop whole lithography apparatus to adorn paper to paper feed mechanism most of the time, can't adorn paper fast in succession, paper feed, waste unnecessary time and cost widely like this, and further reduced work efficiency, be not suitable for accomplishing large-scale printing process output index, for this reason we provide a quick paper feed mechanism for printing machine.

SUMMERY OF THE UTILITY MODEL

In order to overcome the technical insufficiency, the utility model provides a quick paper feed mechanism for printing machine has solved current printing machine paper feed mechanism and can't reach the effect of continuous paper feed under the condition of not shutting down, shuts down the longer technical problem that leads to reducing work efficiency of dress paper time.

Further, the main paper stacking mechanism comprises a main paper stacking table plate and a main paper stacking table lifting mechanism, the main paper stacking table plate is connected with the external frame through the main paper stacking table lifting mechanism, a plurality of uniformly arranged grooves are formed in the main paper stacking table plate, a plurality of corresponding inserting rollers are arranged in the grooves, the initial positions of the inserting rollers are arranged in main equipment of the printing machine, when paper is needed to be loaded, the inserting rollers are inserted into the grooves and ascend along with the main paper stacking table, and then the front table frame and the rear table frame clamp the inserting rollers to support the rest main paper stacking. The roller inserting structure is reasonable in arrangement and flexible in application, plays an extremely important role in the auxiliary paper stacking table lifting mechanism and the main paper stacking table lifting mechanism, and enables the whole paper conveying mechanism to work orderly, efficiently and continuously.

Furthermore, three limit switches are arranged on the side paper blocking plates, the limit switches are respectively an upper limit switch, a middle limit switch and a lower limit switch from top to bottom, the distance between the limit switches can be adjusted according to the requirements of people, generally, a worker adjusts the upper limit switch to the position that the distance between the upper limit switch and the side paper blocking plate is 100mm according to the production requirements, the positions of the upper limit switch and the middle limit switch are kept at about 200mm, because the lower surfaces of the front rack and the rear rack are the highest positions when touching the upper limit switch and the lowest positions when touching the middle limit switch, the highest paper thickness of the auxiliary paper pile is 300mm, the initial position set by the height sensor can be completely matched with the set value of 300mm from the main paper pile board, and the position heights of each limit switch and the height sensor can be automatically adjusted according to the requirements, it is rational in infrastructure, it is extremely nimble convenient to use, has improved paper feed mechanism's efficiency and continuity from structural design furthest.

The utility model discloses a theory of operation does:

when the utility model is used, we focus on explaining the working principle that the whole paper conveying mechanism is interpreted from the characteristics of rapidness, high efficiency and continuity. The utility model discloses before the use, the staff can fix the altitude sensor on the side fender board that is located the below through bolted connection's mode at first to can adjust the high position of confirming the altitude sensor on the side fender board according to the production demand, for example set up it into the height value that is 300mm apart from main pile paper platen. And starting an equipment switch, and starting the paper conveying mechanism to convey paper to the main equipment of the printing machine. When the height of the paper on the main paper pile reaches 300mm, the upper surface of the main paper pile is in flush contact with the lower surface of the height sensor, the height sensor sends a feedback signal to the main body equipment of the printing machine and the lifting mechanism, the insertion roller is driven from the joint of the main body equipment of the printing machine and inserted into the groove of the main paper pile bedplate, the main paper stacking table motor starts the control chain wheel and the chain to drive the main paper stacking table plate to ascend, then the auxiliary paper stacking table motor is started, the front stand and the rear stand descend to the lowest position until contacting the insert roller in the movement process that the chain is driven by the chain wheel to rotate, the front rack and the back rack clamp the inserting rollers in front and back, press the auxiliary paper stacking table lifting button in the main device, the front rack and the back rack drag all the inserting rollers to press the switching switch, after the switching switch is touched, the chain moves in the opposite direction to pull the front rack, the rear rack and the inserting roller to support the rest main paper pile together and lift the main paper pile up automatically and intermittently. The staff presses the main paper stacking table descending button on the main body equipment again, the main paper stacking table plate without paper descends rapidly until the main paper stacking table plate contacts the lower limit switch, at the moment, the paper storing mechanism in the main body equipment of the printing machine starts to load paper on the main paper stacking table plate, and the paper loading is completed after the required paper height is reached.

After the paper loading is finished, a worker presses a main paper stacking platform lifting button on the main device, the main paper stacking platform plate quickly rises until a new main paper stack is contacted with the inserting roller, and the main paper stack is changed from quick rising to intermittent slow rising. At the moment, the front rack and the rear rack move towards the outer side, the clamping state of the opposite insertion roller is converted into a loose state, the auxiliary paper pile supplements the main paper pile, and then the front rack and the rear rack rapidly descend to a middle limit switch in the paper conveying mechanism, namely the lowest position specified by the front rack and the rear rack.
