Description

Technical Field

[0001] The invention belongs to the technical field related to printing machines, and specifically discloses an automatic printing machine. Background Art

[0002] The types of printing machines can be distinguished according to different functions, including letterpress printing machines, gravure printing machines, flatbed printing machines, screen printing machines, inkjet direct printing machines, etc. In the prior art, an inkjet printer is a common digital printing device that uses inkjet technology to spray colors onto paper or other materials to create images or text. When using an inkjet printer, if the relative humidity of the environment in which the inkjet printer is located is low and the air is relatively dry, the solvent in the ink will evaporate more easily, causing the ink to dry faster. When inkjet is sprayed, the ink will be sprayed out along with the jet airflow, and the ink entrained in the airflow will accumulate around the nozzle and at the nozzle hole, and form a precipitate or a gel-like substance. If the nozzle surface is not cleaned in time, the nozzle will be blocked over time, causing the nozzle to be unable to spray ink normally. For this reason, we need to make improvements to this.

[0026] The ink delivery assembly includes an ink tube 6 connected to and installed inside a guide box 7, one end of the ink tube 6 is connected to and installed with an ink box 5, the bottom of the ink box 5 is fixedly installed on the outer wall of one side of the printer body 1 through a placement plate 4, and the end of the ink tube 6 away from the ink box 5 is connected to the inside of the inkjet nozzle assembly 8;

[0027] Reference Manual Attached Figure 1 , Figure 2 and Figure 6 It can be seen that the ink tank 5 supplies ink to the ink tube 6 to the inside of the inkjet head assembly 8, thereby facilitating inkjet printing.

[0028] The lifting assembly includes a second cylinder 16 fixedly arranged on the outer side of the rear end of the lifting slide 12, and the telescopic end of the second cylinder 16 is connected to the upper surface of the connecting seat 9;

[0029] Reference Manual Attached Figure 3 It can be seen that the second cylinder 16 can drive the connecting seat 9 to move up and down, thereby ensuring that the components at the front end of the connecting seat 9 can be close to the inkjet head assembly 8.

[0030] The reciprocating assembly includes a connecting plate 15 fixedly mounted on the bottom of the connecting seat 9, a first cylinder 14 is arranged inside the connecting plate 15, and a telescopic end of the first cylinder 14 is connected to the outside of the collecting box 17;

[0031] Reference Manual Attached Figure 3 It can be seen that the first cylinder 14 can drive the collecting box 17 to flexibly extend and retract, so that the printing will not be hindered when the inkjet nozzle assembly 8 is working.

[0032] The brush head assembly includes a motor 25 fixedly installed below the guide support frame 20, the output shaft of the motor 25 passes through the upper inner side of the guide support frame 20 and is connected to a disc 21 at the end, and a curved column 24 is arranged at equal distances on the upper surface of the disc 21 along the annular direction, and a second flexible rod 36 is arranged on the upper surface of the disc 21 and at a position close to the curved column 24, and a first flexible rod 35 is symmetrically inserted inside the curved column 24, and a plurality of arc heads 37 are arranged at the ends of the first flexible rod 35 and the second flexible rod 36;

[0033] Reference Manual Attached Figure 4 and Figure 5 It can be seen that the motor 25 drives the upper disc 21 to rotate, thereby the bent column 24 , the first flexible rod 35 and the second flexible rod 36 can clean the area around the inkjet nozzle assembly 8 .

[0034] L-shaped blocks 18 are provided on both sides of the rear end of the collection box 17, and a storage platform 19 is installed at the bottom of the two groups of L-shaped blocks 18. Collection boxes 22 are slidably installed on the upper surfaces of the two storage platforms 19, and a pull rod 23 is fixedly installed on the outer side of one end of the collection box 22 away from the L-shaped block 18, and the collection box 22 is connected to the inside of the collection box 17;

[0035] Reference Manual Attached Figure 3 and Figure 4 It can be seen that, through the connection of the L-shaped block 18 , the storage table 19 can allow the collection box 22 to be stably set below the collection box 17 , and the blown-off dirt directly falls into the collection box 17 and is collected by the collection box 22 .

[0036] A storage rack 13 is arranged at the front end of the connecting seat 9, a cover rod 29 is slidably installed inside the storage rack 13, a connecting pipe 30 is embedded on the upper inner side of the cover rod 29, an air bag 32 is connected and installed at one end of the connecting pipe 30, an air nozzle 31 is connected and installed at equal distances along the annular direction inside the air bag 32, a cleaning ring 34 is arranged on the inner wall of the cover rod 29, a fan 28 is connected and installed at one end of the connecting pipe 30 away from the cover rod 29, the fan 28 is fixedly arranged on the inner side of the storage rack 13 and close to the cover rod 29, and a buffer is arranged on the outer side of the cover rod 29;

[0037] Reference Manual Attached Figure 7 and Figure 8 It can be seen that the connecting tube 30 is embedded in the inner side of the cover rod 29 and can be retracted and extended synchronously with the cover rod 29. The fan 28 can deliver the airflow to the airbag 32 under the connection of the connecting tube 30. The airbag 32 is made of polyurethane material. When it contacts the first flexible rod 35, it can shrink by its own ductility and also change the spray direction of the air nozzle 31. Combined with the inclined surface of the cleaning ring 34 itself to guide the airflow, the airflow covers the inside of the cover rod 29 in all directions.

[0038] The connecting pipe 30 is a corrugated hose.

[0039] The buffer member includes a sleeve 33 disposed above the outer side of the cover rod 29, a spring 27 is disposed outside the cover rod 29 and above the sleeve 33, a mounting plate 38 is slidably sleeved above the outer side of the cover rod 29, and both ends of the inner side of the mounting plate 38 are fixed to the upper surface of the rack 13 by means of fixed rods 26;

[0040] Reference Manual Attached Figure 6 and Figure 7 It can be seen that the sleeve 33 can flexibly allow the cover rod 29 to perform elastic buffering as the bending column 24, the first flexible rod 35 and the second flexible rod 36 are squeezed, thereby reducing hard pulling. The spring 27 can perform elastic buffering above the cover rod 29 through the sleeve 33. The fixing rod 26 and the mounting plate 38 ensure that the position of the cover rod 29 is limited when it is telescopic, thereby ensuring that the cover rod 29 can be used well.

[0041] Working principle: After printing is completed, the corresponding second cylinder 16 and the first cylinder 14 can drive the front collection box 17 to be placed under the inkjet nozzle assembly 8, and the motor 25 drives the disc 21 to rotate, prompting the multiple curved columns 24, the first flexible rod 35 and the second flexible rod 36 to rotate around the inkjet nozzle assembly 8. The multiple arc heads 37 at one end of the first flexible rod 35 mainly clean the outer surface of the inkjet nozzle assembly 8, and the multiple arc heads 37 corresponding to the second flexible rod 36 mainly clean the nozzle of the inkjet nozzle assembly 8. The arc head 37 is hollow inside and semi-circular in shape, which can pull the accumulated ink filaments and sediments, and then during the rotation process, the accumulated materials around the inkjet nozzle assembly 8 can be taken out, and the accumulated materials adhere to the outer side of the arc head 37 and the curved column 24. When the collection box 17 is retracted to the bottom of the rack 13, the corresponding disc 21 will move to the bottom of the inner side of the cover rod 29, located inside the rack 13. The fan 28 conveys the airflow to the airbag 32 through the connecting pipe 30, and then sprays it out through multiple air nozzles 31, thereby achieving the purpose of self-cleaning. When the disc 21 drives the bent column 24, the first flexible rod 35 and the second flexible rod 36 to rotate, the first flexible rod 35 will come into active contact with the airbag 32, and can squeeze the airbag 32 during contact, thereby allowing the air nozzle 31 to change the original direction of the airflow. In the process, the dirt on the surface of the arc head 37 inside the cover rod 29 can be blown away by multiple recoil airflows. In addition, the outer surface of the cleaning ring 34 is arranged in an inclined surface, so when the airflow is blowing, it can also disturb the airflow through the guidance of its own inclined surface. In this way, the arc heads 37 in different directions can be uniformly descaled. After being cleaned, the dirt falls into the collection box 22 on both sides of the collection box 17 below, which also saves the work of cleaning the printing layout board 2. Later, the user pulls out the pull rod 23 to centrally process the dirt inside the collection box 22.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
