Description

Technical Field

[0002] As a highly efficient printing equipment, rotary printing press is mainly used for large-scale production of high-quality printed materials. Most rotary printing presses on the market print on continuous roll paper, and are characterized by high speed and high efficiency. Currently, the common rotary printing presses on the market have a speed of more than 30,000 copies / hour, and some even exceed 70,000 copies / hour.

[0003] Since the printed content varies, it is sometimes impossible to typeset across the entire sheet of paper. In order to improve printing efficiency and save paper, it is necessary to print two copies of the same content on each full sheet of paper. After the rotary printing machine prints, folds, and cuts the paper, the two copies of the same content are pulled out for processing in subsequent steps. Currently, there is no equipment on the market that can realize this page pulling function, so page pulling is done manually.

[0004] Since rotary printing machines are fast and efficient, manual page pulling is far from meeting the demand. The current solution of printing factories is to increase the number of page pullers or to leave some papers blank during typesetting. This is not only inefficient, but also wastes a lot of paper.

[0020] Beneficial Effects

[0021] The present invention provides a printing paper extraction device based on rotary printing. Compared with the prior art, it has the following beneficial effects:

[0022] (1) By setting up a pulling mechanism and utilizing the movement of two groups of suction nozzles, the two corners of two folded printed papers are sucked in turn.

[0024] (3) By setting up a flap assembly, the printed paper is placed on the carrier plate of the saddle at a certain angle, which facilitates the pulling and unfolding of the outer printed paper, thereby facilitating the extraction of the inner printed paper. The chain drives the carrier plate and the push plate to perform reciprocating motion, which can realize the feeding of the printed paper and the unloading of the printed paper after extraction, thereby improving the efficiency and continuity of the extraction of the printed paper.

[0025] (4) An electrostatic unit is provided and a ball screw is used to drive the slide tube to reciprocate, so that the silk cloth and the glass rod are repeatedly rubbed to generate static electricity. Through the conduction effect of the connecting rod and the slide bar, when the carrier plate drives the printed paper to move to the extraction station, the carrier plate absorbs the other side of the outer printed paper through static electricity, so as to improve the smoothness of extraction and the stability of the printed paper.

[0026] (5) By setting up a linkage module, when the external pneumatic equipment uses air flow to make the air nozzle adsorb and detach the printed paper, the two sets of blades and the flowing air are set up so that the rotating rod can drive the ball screw to perform unidirectional reciprocating motion, thereby continuously generating static electricity.

[0046] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 1 , Attachment Figure 5 ;

[0047] An electrostatic unit 34 is arranged on the outside of the carrier plate 33. The electrostatic unit 34 includes a glass rod 341. A sliding tube 342 is sleeved on the outer surface of the glass rod 341. The cross-sections of the interior of the sliding tube 342 and the end of the glass rod 341 are rectangular to improve the radial stability during sliding. A silk cloth 343 is embedded and fixedly connected to the interior of the sliding tube 342. There are multiple groups of glass rods 341 and silk cloth 343. Static electricity is generated by reciprocating friction and can also be replaced by rubber rods and fur.

The connecting rod 344 is made of conductive material and can be replaced by a wire to transmit the generated static electricity. One end of the connecting rod 344 is fixedly connected to a sliding bar 345. The sliding bar 345 is made of conductive material. The slide bar 345 is made of electrical material to transmit the generated static electricity, and the slide bar 345 corresponds to the mirror image side of the suction nozzle 2 and is located on the conveying path after the printed paper is pulled out.

When the carrier plate 33 moves to the removal station with the printed paper, the carrier plate 33 contacts the slide bar 345 to carry static electricity to adsorb the other side of the outer printed paper, so as to improve the stability during removal. After the printed paper is removed, while continuing to move with the carrier plate 33, the static electricity elimination fan eliminates the static electricity on the carrier plate 33 to facilitate the unloading of the printed paper.

[0049] Embodiment 5: Based on Embodiment 4, refer to the attached Figure 1 , Attachment Figure 6 ;

[0050] A linkage module 348 is provided on the outside of one end of the ball screw 347, and the linkage module 348 includes a connecting tube 3481, one side of the connecting tube 3481 is connected to the external pneumatic equipment, the connecting tube 3481 is arranged on the outside of the bracket 346, and a rotating rod 3482 is rotatably connected to the inside of the connecting tube 3481, and an axial limiting measure is provided for the connection between the rotating rod 3482 and the connecting tube 3481, one end of the rotating rod 3482 is fixedly connected to the end of the ball screw 347 through a coupling, and two groups of opposite blades 3483 are fixedly connected to the outer surface of the rotating rod 3482, and the two groups of blades 3483 are arranged in different directions through the rotation angle, so that the rotating rod 3482 drives the ball screw 347 to perform a unidirectional reciprocating motion through contact with the incoming and outgoing air, and the outer surfaces of the two groups of blades 3483 are both connected to the internal rotation of the connecting tube 3481 Next, two guide seats 3484 are arranged between the outer surfaces of the two groups of blades 3483. The guide seats 3484 are truncated cone-shaped, which can guide the flowing air outward to prevent the flowing air from contacting the opposite blades 3483 and affecting the stability and driving force of the rotating rod 3482. The bodies of the two guide seats 3484 are both penetrated and fixedly connected with the outer surface of the rotating rod 3482. One end of the connecting pipe 3481 is penetrated and connected with a solid box 3485. The outer surface of the solid box 3485 is fixedly connected with the outer surface of the frame 1.

One end of the pneumatic valve 3486 is connected with a spring tube 3487. The extension and retraction of the spring tube 3487 can facilitate the movement of the suction nozzle 2. One end of the spring tube 3487 is connected with one end of the suction pipe 4.

[0051] In this embodiment, when it is necessary to drive the suction nozzle 2 to suck the printed paper to be extracted, the external pneumatic equipment extracts the air inside the suction nozzle 2 or injects air into it through the connecting tube 3481, the fixed box 3485, the pneumatic valve 3486, the spring tube 3487 and the suction tube 4. When the air flows inside the connecting tube 3481, it contacts with the paddle 3483 on one side, so that the paddle 3483 drives the ball screw 347 to rotate through the rotating rod 3482, so as to provide power for the friction generated by static electricity. At the same time, after the air contacts with the paddle 3483 on one side, the air is dispersed and guided to the inner wall of the connecting tube 3481 through the corresponding guide seat 3484, so that the air will not contact with the paddle 3483 on the other side, thereby avoiding the problem of poor stability and driving force of the rotating rod 3482.
