Description

Technical Field

[0001] The utility model relates to the field of publication printing machines, in particular to a dust suction device used for publication printing machines. Background Art

[0002] A publication printing press is a machine that prints patterns or texts onto paper, textiles, metals and other objects. It is the most important equipment in the printing industry and is widely used in different fields, such as commercial printing, publication printing, packaging printing, etc. Publications will generate a lot of dust during the printing process, which requires the use of a dust suction device. The dust suction device generates negative pressure and uses the principle of airflow to suck the dust into the device. In short, it uses the fluidity of airflow and the effect of pressure difference, and is widely used in printing, chemical industry, machinery, textile, casting and other fields.

[0003] After searching, a dust suction device of a printing press with publication number CN213920221U is found, which specifically discloses a dust suction device of a printing press, including a base frame, a plug hole is opened on the left side of the base frame, the top of the base frame is fixedly connected with a water storage tank body, the bottom of the water storage tank body is fixedly connected with a booster pump, the outer side of the water storage tank body is fixedly connected with a connecting ring, the inner side of the connecting ring is plugged with a dust removal hood body, the inner top wall of the dust removal hood body is fixedly connected with an atomizing nozzle, the right side wall of the dust removal hood body is fixedly connected with an isolation net, the right side of the dust removal hood body is fixedly connected with an exhaust fan, the left side of the dust removal hood body is fixedly connected with a dust suction pipe, the right side of the dust suction pipe is fixedly connected with a pull rod, the bottom end of the dust suction pipe is fixedly connected with a dust suction hood, four through holes are opened on the outer side of the connecting ring, and four threaded grooves are opened on the outer side of the dust removal hood body. The dust suction device of the printing press is easy to move and has a good dust suction processing effect.

[0004] During the use of the existing dust suction device of the publication printing machine, the dust contaminated by the publication during the printing process does not directly adhere to the printed material, but is partially deposited inside the printing machine and mixed with the publication. In this way, the dust suction device only absorbs the surface dust alone, and cannot effectively complete the dust suction work of the publication printing machine. In addition, the above-mentioned comparative case also lacks other methods for sucking the deposited dust. In this way, after long-term use, not only is the dust removal efficiency of the publication low, but the deposited dust still accumulates inside the publication printing machine and needs to be manually cleaned.

[0005] Therefore, it is necessary to invent a dust suction device that is used for publication printing press to solve the above problems. Utility Model Content

Compared with the dust suction means of only sucking the dust on the surface alone, this not only improves the overall dust suction efficiency of the device, but also reduces the probability of dust remaining inside the publication printing machine, avoids the manual cumbersome cleaning method, makes the dust suction more thorough during the publication printing process, strengthens the dust suction effect, and makes the publication more tidy after printing, so as to solve the problem of dust suction. In the prior art, during the use of the dust suction device of the publication printing machine, the dust contaminated by the publication during the printing process is not directly attached to the printed material, but partly settles inside the printing machine and is mixed with the publication. In this way, the dust suction device only absorbs the surface dust alone, and cannot effectively complete the dust suction work of the publication printing machine. In addition, the above-mentioned comparative case also lacks other methods for sucking the settled dust. In this way, after long-term use, not only the dust removal efficiency of the publication is not high, but the settled dust still accumulates inside the publication printing machine and needs to be manually cleaned.

[0029] The middle cross frame 5 is arranged inside the machine body 1 and is used for connecting and installing the electric conveyor belt 6. A fixing frame 7 is fixedly installed above the middle cross frame 5. A positioning screw 8 is passed through the top of the fixing frame 7. A pressing plate 9 is fixedly installed at one end of the positioning screw 8.

[0030] A first vacuum air pump 10 is arranged at the top of the machine body 1, and is used to provide gas to the mist nozzle 14. An air supply pipe 11 is fixedly installed at one end of the first vacuum air pump 10. A movable shaft 12 is arranged inside the machine body 1. A transfer cavity 13 is fixedly installed outside the movable shaft 12. A mist nozzle 14 is arranged at the bottom of the transfer cavity 13. A telescopic cylinder 15 is arranged on one side of the transfer cavity 13. A spacer filter 16 is fixedly installed below the middle cross frame 5.

[0031] The second vacuum air pump 17 is arranged on the outside of the body 1, and is used for vacuuming the internal dust. An exhaust pipe 18 is fixedly installed at one end of the second vacuum air pump 17, and a dust suction port 19 is fixedly installed at the other end of the exhaust pipe 18. A diversion pipe 20 is fixedly installed at the other end of the second vacuum air pump 17. The second vacuum air pump 17 provides suction to the dust suction ports 19 on both sides to suck all the raised dust into the vacuuming and dust removal work. Compared with the vacuuming method of only sucking the surface dust alone, the method of first stirring up the dust and then vacuuming not only improves the overall vacuuming efficiency of the device, but also reduces the probability of dust remaining inside the publication printing machine.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a roller 2 is fixedly installed on the bottom of the body 1, a docking port 3 is fixedly installed on one side of the body 1, and a printing machine body 4 is fixedly installed on the other side of the docking port 3. The device is conveniently docked and installed with any printing machine body 4 through the roller 2. The clamping plate 9 is movably connected to the middle cross frame 5, and the positioning screw 8 is symmetrically arranged with the central axis of the middle cross frame 5. The height of the clamping plate 9 can be adjusted by twisting the positioning screw 8 according to the thickness of the current publication to fix the publication on the electric conveyor belt 6. The number of mist nozzles 14 is set to six, and the six mist nozzles 14 are evenly spaced on the transfer cavity 13. The first vacuum air pump 10 provides gas to the mist nozzle 14, which blows toward the publication limited by the clamping plate 9, so that not only the printing smell of the publication itself can be blown away, but also the precipitated dust can be stirred up.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a fixed slide rail 21 is provided inside the body 1, and a fixed slide sleeve 22 is movably connected to the outside of the fixed slide rail 21, and a dust box 23 is fixedly installed at one end of the fixed slide sleeve 22. The fixed slide rail 21 and the fixed slide sleeve 22 can quickly draw out the dust box 23 after vacuuming is completed, and the dust stored inside is processed in time to ensure the normal use of the device. The dust box 23 is slidably connected to the body 1, and the fixed slide sleeve 22 is used in conjunction with the fixed slide rail 21. The dust box 23 has a simple structure and low cost. If a fault occurs, it is convenient to replace it in time without delaying the normal use of the device.

[0034] The working principle of the utility model is as follows: firstly, the external power supply is connected, and the roller 2 and the docking interface 3 are conveniently connected and installed with any printing machine body 4, and then, according to the thickness of the publications that need to be vacuumed, the positioning screw 8 is twisted to adjust the height of the pressing plate 9 to fix the publications on the electric conveyor belt 6, and then the switch of the telescopic cylinder 15 is turned on, and the transfer cavity 13 is driven to adjust the angle on the movable shaft 12 through the telescopic cylinder 15, so that the mist nozzle 14 is aimed at the electric conveyor belt 6 below, and the preparation work is completed, and the utility model can be opened. The switch of the electric conveyor belt 6 is turned on. The electric conveyor belt 6 drives the printed publications from the printing machine body 4 to the machine body 1. In this way, the entire dust removal process is transferred to the machine body 1 to be completed, reducing the loss of the agitated dust to the printing machine body 4. Then the switch of the first vacuum air pump 10 is turned on. The first vacuum air pump 10 draws external air through the air supply pipe 11 to provide gas to the mist nozzle 14, and blows it to the publication limited by the pressing plate 9. This can not only blow away the printing smell of the publication itself, but also stir up the precipitated dust, so that all the dust is splashed Inside the machine body 1, the switch of the second vacuum air pump 17 is then turned on, and the suction ports 19 on both sides are provided with suction force by the second vacuum air pump 17, so that all the raised dust is sucked in to complete the dust collection and dust removal work, and the dust is all put into the dust box 23 for storage through the shunt pipe 20. In this way, the means of first stirring up dust and then sucking dust is compared with the dust collection means of only sucking the dust on the surface alone, which not only improves the overall dust collection efficiency of the device, but also reduces the probability of dust remaining inside the publication printing machine, and avoids the manual cumbersome cleaning method. After the dust collection is completed, the dust box 23 is quickly extracted through the fixed slide rail 21 and the fixed slide sleeve 22, and the dust stored inside is processed in time to ensure the normal use of the device. Finally, after completing the installation and use of the dust collection device of the entire publication printing machine according to the above operation, turn off the switch of the electric conveyor belt 6, turn off the switches of the first vacuum air pump 10 and the second vacuum air pump 17, turn off the switch of the telescopic cylinder 15, and cut off the external power supply if it is not used for a long time. In this way, the use process of the dust collection device for the publication printing machine is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
