Description

Technical Field

[0001] The utility model relates to the technical field of book and periodical printing machines, and particularly relates to a flat book and periodical printing machine convenient for replacing web paper. Background Technique

[0002] At present, in the process of printing books and periodicals, a printing machine is an essential device. A printing machine is a machine for printing words and images. In the production of books and periodicals, printing is usually carried out sheet by sheet, and then binding is carried out after printing. The printing speed of the printing machine is fast and the printing quality is good.

[0003] During the printing process of books and periodicals, since there is inevitably dust in the air, the dust will stay on the surface of the driving wheel through static electricity and adhere to the paper during the printing process, affecting the printing effect. Moreover, before printing the paper, it is necessary to manually transport the paper to the printing main body for printing, which consumes manpower and has a certain adverse impact on the paper production process.

[0004] As disclosed in a book and periodical printing machine of Chinese Patent CN214522706U, through the provided dust-brushing mechanism, during the installation process of the dust-brushing mechanism, first place the whole dust-brushing mechanism on the inner surfaces of both sides at the front end of the printing main body, then place the whole dust-brushing mechanism with the bristles facing up, and then simultaneously twist the two screw sleeves. During the twisting process of the two screw sleeves, the two fixed studs slide relatively left and right along the fixed rod and extend until the two fixed suction cups are attached to the inner surfaces of both sides at the front end of the printing main body. After the air inside the two fixed suction cups is emptied, the fixing effect can be achieved by using the principle of atmospheric pressure. During the operation of the device, the driving wheel rotates while contacting the bristles, so as to achieve the dust-removing effect. The structure of the dust-brushing mechanism is simple and convenient to disassemble and assemble, avoiding dust from adhering to the paper and further ensuring the printing effect.

[0005] However, this device is not convenient to replace the web paper during use, thus affecting the printing efficiency.

[0006] Therefore, we urgently need to provide a flat book and periodical printing machine convenient for replacing web paper. Content of the Utility Model

[0007] The purpose of the utility model is to provide a flat book and periodical printing machine convenient for replacing web paper, so as to solve the problem that it is not convenient to replace the web paper during use in the above-mentioned background technique, thus affecting the printing efficiency.

[0008] To achieve the above purpose, the utility model provides the following technical solution: a flat book and periodical printing machine convenient for replacing web paper, including a frame and a rotating shaft, the rotating shaft is installed inside the frame, and a processing device is arranged inside the frame.

[0009] The processing device includes a disassembly and assembly unit and a dust removal unit. The disassembly and assembly unit is arranged inside the frame, and the dust removal unit is arranged on the top of the frame.

[0010] The disassembly and assembly unit includes a fixed sleeve, a first connecting plate, a second connecting plate, a first spring, a motor, an output shaft, a chuck, a second spring, a pull rod and a reel. The fixed sleeve is installed on the outer surfaces of the left and right sides of the rotating shaft. The first connecting plate is fixedly installed on the front and rear sides of the outer surface of the left fixed sleeve. The second connecting plate is fixedly installed on the front and rear sides of the outer surface of the right fixed sleeve. The first spring is installed inside the second connecting plate.

The chuck is installed at the front and rear ends inside the output shaft. The second spring is installed inside the output shaft. The pull rod is fixedly installed at one end of the chuck. The reel is installed between the first connecting plate and the second connecting plate.

[0011] Preferably, the dust removal unit includes a collection box, a suction fan, a connecting pipe and a suction head. The collection box is installed on the left and right sides of the top of the frame. The suction fan is connected to one side of the collection box. The connecting pipe is connected to the output end of the suction fan. The suction head is connected to the bottom of the connecting pipe.

[0012] Preferably, an installation groove is formed inside the second connecting plate, and the first spring is installed inside the installation groove. The installation groove facilitates the installation of the first spring.

[0013] Preferably, a connecting groove is formed on the right side surface of the output shaft, and placement grooves are formed at the front and rear ends of the output shaft. The chuck and the second spring are installed inside the placement grooves. The placement grooves facilitate the installation of the chuck and the second spring.

[0014] Preferably, card holes with the same diameter as the chuck are formed at the front and rear ends on the left side of the reel. By clamping the chuck with the card holes, the reel is conveniently fixed between the first connecting plate and the second connecting plate.

[0015] Preferably, the dust removal units are distributed on the left and right sides of the top of the frame.
