Technical Field

[0001] The utility model relates to the technical field related to offset printing machines, in particular to a transmission mechanism of an offset printing machine. Background Art

[0002] An offset printing press is a type of lithographic printing press that operates based on the principle that oil and water do not mix. An offset printing press generally consists of three main components: the paper feed section, the printing section, and the paper delivery section. The paper drive mechanism is a key component of the offset printing press, playing a vital role in accurately transporting paper during the printing process.

[0003] The existing paper transmission mechanism has low transmission efficiency and poor effect, resulting in low production efficiency. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of low efficiency and poor transmission effect of the paper transmission mechanism of the offset printing press in the prior art and provides a transmission mechanism of the offset printing press with high paper transmission efficiency and good transmission effect.

[0005] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solution: a transmission mechanism of an offset printing machine, including a transmission frame, a paper storage slot for storing paper is provided at the rear end of the transmission frame, a swingable suction cup assembly is installed above the paper storage slot, a paper pushing block that can be pushed outward is installed on the side wall of the transmission frame, pushing rollers that can move inward are installed on both sides of the transmission frame, a rotatable rolling tooth row is installed in the middle of the transmission frame, and a plurality of paper feed rollers are installed at the front end of the transmission frame.

[0006] The transmission mechanism comprises a transmission frame, wherein a paper storage slot is provided at the rear end of the transmission frame for storing paper. A suction cup assembly is mounted above the paper storage slot, which absorbs the paper. The suction cup assembly is swivellable, and the swinging motion of the suction cup assembly absorbs the paper and moves it, thereby transferring the paper. Furthermore, a paper pusher block is mounted on the side wall of the transmission frame. The pusher block is retractable and can be pushed outward to push the paper out, thereby transferring the paper. Furthermore, push rollers are mounted on both sides of the transmission frame. The push rollers can move inward, and the push rollers on both sides can tilt the middle of the paper. Simultaneously, the push rollers can rotate, driving the paper forward, thereby transferring the paper. A rolling tooth bar is mounted on the transmission frame, which can accurately transmit the paper forward, and then enter the paper feed roller mounted at the front end of the transmission frame. The rotation of the paper feed roller transfers the paper to the printing section of the offset printing press. This structure achieves smooth transmission of paper through the coordination of multiple components, with good transmission effect, thereby improving production efficiency.

[0007] Preferably, a support plate is mounted at the bottom of the paper storage trough, and a telescopic push rod is mounted at the lower end of the support plate, and the telescopic push rod is connected to the transmission frame. During production, paper is placed on the support plate, and the telescopic push rod's telescopic function ensures that the paper always meets the transmission requirements, thereby ensuring the paper transmission effect.

[0008] Preferably, a rubber block is mounted at the bottom of the paper pusher block, the rubber block being cylindrical, and the paper pusher block is connected to a telescopic rod, which is connected to the transmission frame. The paper pusher block is mounted on a side wall of the transmission frame via the telescopic rod. When paper is being transmitted, the telescopic rod pushes the paper pusher block outward, and the rubber block at the lower end of the paper pusher block, when in contact with the paper, pushes the paper, thereby achieving paper transmission, improving paper transmission efficiency, and increasing production efficiency.

[0009] Preferably, the transmission frame is provided with a conical air blowing nozzle at the end thereof, and the air blowing nozzle is positioned on both sides of the paper pushing block. The air blowing nozzles mounted on the transmission frame have conical ends and are mounted at both ends of the paper pushing block. When the paper pushing block contacts the paper, the air blowing nozzles, via an external air pump, blow air toward the paper, creating gaps between the stacked sheets, thereby improving transmission efficiency and increasing production efficiency.

[0010] Preferably, a mounting block is mounted on the side of the transmission frame, a push rod is mounted on the mounting block, the end of the push rod is connected to a push roller, and a rolling motor is mounted inside the push roller. A mounting block is mounted on the side of the transmission frame via bolts, a push rod is mounted on the mounting block, the push rod realizes its pushing function via a telescopic cylinder, and a rolling motor is mounted inside the push roller mounted on the end of the push rod. When paper is transmitted, the push rod is pushed outward, pushing the edges of the paper inward, causing the paper to bulge. At the same time, the rolling motor in the push roller rotates to push the paper toward the front end, thereby realizing paper transmission. This structure facilitates the forward pushing of paper and improves its transmission effect.

[0011] Preferably, the suction cup assembly includes a rotating block, a rocker arm, and a nozzle block. The rotating block is mounted on the top of the transmission frame, the rocker arm is connected to the rotating block, the nozzle block is hinged to the rocker arm, and the nozzle block is a conical structural block made of rubber. A rotating block is provided in the suction cup assembly, and a rocker arm is mounted on the rotating block. The rotating block can drive the rocker arm to rotate, and is connected to the nozzle block at the lower end of the rocker arm by a hinge. At the same time, the nozzle block is a block made of rubber material, and the structure is conical. The nozzle block is connected to an external vacuum pump through a connecting tube. When paper is transmitted, the rotating block places the rocker arm in a vertical state, and the nozzle block absorbs the paper through the vacuum pump. Then the rotating block swings forward, driving the paper forward to complete the paper transmission. This structure facilitates the forward push of the paper and improves its transmission effect.

[0012] Preferably, the rolling tooth row includes a rolling rod and a plurality of rolling tooth blocks, the rolling tooth blocks being connected to the rolling rod, a fixed block being mounted on the side wall of the transmission frame, the rolling rod being rotatably connected to the fixed block, and the rolling rod being externally connected to a drive motor. The rolling tooth row includes a rolling rod and a rolling tooth block, the rolling tooth block being made of rubber, a fixed block being mounted on the front end of the transmission frame, the rolling rod being mounted on the fixed block, and a drive motor being mounted on the fixed block. The drive motor can drive the rolling rod to rotate, thereby driving the rolling tooth blocks to contact the paper, completing the paper transmission. The paper is then transmitted to the paper feed roller by the rolling of the rolling tooth blocks, ensuring a stable paper transmission effect.

[0013] The beneficial effect of the utility model is that the mechanism completes the transmission of paper by adopting a retractable paper pushing block, an outward blowing nozzle, an inward pushing pushing roller and a rolling tooth row installed on the transmission frame to cooperate with each other, realizing a composite action of paper transmission, thereby improving the effect of paper transmission and improving production efficiency.
