Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a feeding device for a printing machine. Background Art

[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is: first the text and image to be printed are made into a printing plate and mounted on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] According to the "A feeding device for a packaging printing machine" disclosed in Chinese patent publication No. CN212884057U, a vacuum cleaner is set up, which includes a controller, a power socket, a fan impeller, a dust filter bag, a dust collection box and a dust suction pipe. The power is connected through the power socket. There is a driving machine inside the vacuum cleaner. After the power is turned on, the driving machine rotates at a speed of 1 / 2 per second under the action of suction and pressure. The air is discharged at high speed through the in and out principle of air flow, while the other end becomes a strong suction port to suck out garbage and dust, and the air in the dust suction pipe at the lower end of the fan impeller continuously replenishes the air in the fan, causing an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure difference with the external atmospheric pressure. Under the action of this pressure difference, dust-containing air is inhaled, and dust and other debris are sucked into the dust filter bag through the dust suction pipe. After the air is purified by the dust filter bag, it is sucked out by the suction pipe. The gas discharged from the tail of the dust collector is hot because it is heated when passing through the driving machine. The dust filter bag is connected to the dust box, and the dirt is left in the dust box. After the box is full, it can be taken out and cleaned with water, which is conducive to pre-dust removal of the equipment to prevent dust from falling on the printing materials and reducing product quality. The sound-absorbing box is set up, and there is a sound-absorbing board inside the sound-absorbing box. The sound-absorbing board is finely processed according to the acoustic principle and consists of a facing, a core material and a sound-absorbing thin felt. It uses the resonance sound absorption principle of the thin plate. At the resonant frequency, the thin plate absorbs a lot of sound energy due to the violent vibration. When the equipment is running, the sound-absorbing board can effectively absorb noise, which is conducive to providing workers with a good working environment. The whole feeding device of a packaging printing machine has a simple structure and is easy to operate. The effect of use is better than that of the traditional method.

[0004] However, since the thicknesses of different printed materials are different, the above-mentioned feeding device does not have an adjustment function. When feeding printed materials of different thicknesses, the equipment needs to be stopped for manual adjustment, which is time-consuming and labor-intensive, and affects the feeding efficiency.
