[0002] Printing machinery is a machine that prints text and images. When printing machinery processes the surface of printed materials, in order to improve the printing effect, corresponding dust removal devices are usually set up to clean the impurities and dust attached to the surface of the printed materials.

[0003] For example, in the case of an automatic dust removal device for a printing press (publication number CN204340379U), the printing press includes a printing work platform. The dust removal device includes a fan and three dust suction hoods and three air blowing hoods symmetrically arranged on both sides of the printing work platform. The fan is located below the printing work platform. The three dust suction hoods are each connected to a main exhaust pipe via their respective exhaust ducts. The main exhaust pipe is connected to the air inlet of the fan. The three air blowing hoods are each connected to a main exhaust pipe via their respective air blowing ducts. The main exhaust pipe is connected to the air outlet of the fan. A filter screen is installed at the connection between the main exhaust pipe and the fan. The above-mentioned prior art has the following technical problems:

[0004] Existing dust removal devices can only clean dust and impurities on the surface of printed products by using negative pressure suction. While this can achieve a certain cleaning effect, it is insufficient to effectively handle stubborn impurities with strong adhesion to the surface of printed products, thus reducing the overall dust removal and cleaning effect.

[0005] Therefore, we propose a high-efficiency dust removal device for printing machinery to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency dust removal device for printing machinery, in order to solve the problem mentioned in the background art that the existing dust removal devices on the market can only clean the dust and impurities on the surface of printed products by means of negative pressure suction. Although it can achieve a certain cleaning effect, it is not effective in dealing with stubborn impurities with strong adhesion to the surface of printed products by means of negative pressure alone, thereby reducing the overall dust removal and cleaning effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency dust removal device for printing machinery, comprising a connecting frame, a negative pressure fan installed at the upper end of the connecting frame, the negative pressure fan being connected to a flow hose and a diverter plate, a negative pressure suction head installed on the side of the diverter plate facing the inside of the connecting frame, a servo motor fixed on the upper left side of the connecting frame, the output end of the servo motor being connected to the rotating shaft of a cleaning roller brush via a pulley, the rotating shaft of the cleaning roller brush being mounted on the connecting frame via bearings, a power rod installed in the middle of the rotating shaft of the cleaning roller brush, an impact block fixed at one end of the power rod extending into the inside of the cleaning roller brush, the impact block being connected to the cleaning roller brush via a built-in spring, the end of the power rod away from the impact block extending out of the rotating shaft on the side of the cleaning roller brush, and a first magnetic block embedded at the end of the power rod extending out of the rotating shaft on the side of the cleaning roller brush, a second magnetic block fixed on the side of the first magnetic block.

[0008] Preferably, the cleaning roller brush has rubber bristles evenly distributed around its circumference, and the cleaning roller brush is able to rotate on the connecting frame.

[0009] By adopting the above technical solution, the rubber bristles on the cleaning roller can be used to clean impurities attached to the surface of printed materials.

[0010] Preferably, the interior of the flow divider is a hollow structure, and the flow divider is connected to the outside through a negative pressure suction head, and multiple negative pressure suction heads are provided on the flow divider.

[0011] By adopting the above technical solution, multiple negative pressure suction heads evenly distributed on the side of the diverter plate can remove the dust generated during the cleaning process.

[0012] Preferably, the longitudinal section of the power rod is set as a "T" shaped structure, and the impact block fixed at the end of the power rod is in contact with the interior of the cleaning roller in the initial state.

[0013] By adopting the above technical solution, the movement of the power rod can drive the impact block to move synchronously, and the movement of the impact block can then impact the cleaning roller brush.

[0014] Preferably, the first magnetic block is symmetrically arranged about the transverse central axis of the power rod, and the magnetism of the first magnetic block and the magnetism of the second magnetic block are opposite.

[0015] By adopting the above technical solution, when the power rod rotates with the cleaning roller brush, the first and second magnetic blocks at the end of the power rod approach each other, thereby enabling the power rod to move under magnetic force.

[0016] Preferably, the upper outer side of the power rod is provided with a snap-fit ​​side plate, and the snap-fit ​​side plate is fixed to the diverter plate. A limiting rod fixed on the connecting frame is inserted through the upper end of the diverter plate, and the diverter plate is connected to the connecting frame through an auxiliary spring.

[0017] By adopting the above technical solution, the auxiliary spring can be used to enable the diverter plate to reset and rebound after moving on the limit rod.

[0018] Preferably, the upper inner wall of the diverter plate and the outer wall of the limiting rod are in contact with each other, and the diverter plate can slide on the limiting rod.

[0019] By adopting the above technical solution, the movement of the diverter plate enables the negative pressure suction head on its side to move synchronously, thereby increasing the suction range.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the high-efficiency dust removal device for printing machinery, by setting a rotatable roller brush, can reduce the adhesion of stubborn stains by utilizing the contact between the roller brush and the surface of the printed product when the roller brush rotates, and at the same time, the negative pressure dust collection method can improve the removal effect of dust and impurities on the surface of the printed product.

The rotation of the cleaning roller brush can clean the impurities attached to the surface of the printed materials. At the same time, the negative pressure generated by the negative pressure fan can be used to adsorb external dust through the diverter plate and negative pressure suction head.

[0022] 2. An impact block is provided. The rotation of the cleaning roller brush can drive the power rod to rotate synchronously. After the power rod rotates, the distance between the first and second magnetic blocks changes, causing the power rod and the impact block to move back and forth. The vibration generated by the impact block hitting the cleaning roller brush through the reciprocating movement can shake off the impurities and dust attached to the cleaning roller brush.

[0023] 3. It is equipped with a snap-fit ​​side plate. The reciprocating movement of the power rod can drive the snap-fit ​​side plate to move synchronously. The movement of the snap-fit ​​side plate can cause the diverter plate to move synchronously. By using the movement of the diverter plate and the negative pressure suction head, the overall suction range can be increased during vacuuming. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: Please refer to Figures 1-5Existing dust removal devices can only clean dust and impurities on the surface of printed products using negative pressure suction. While this method achieves some cleaning effect, it is insufficient for stubborn impurities with strong adhesion to the surface of printed products, thus reducing the overall dust removal efficiency. To address this technical problem, this embodiment discloses the following technical content: a high-efficiency dust removal device for printing machinery, including a connecting frame 1. A negative pressure fan 5 is installed at the upper end of the connecting frame 1, and the negative pressure fan 5 is connected to a flow hose 6 and a diverter plate 7. A negative pressure suction head 8 is installed on the side of the diverter plate 7 facing the inside of the connecting frame 1. A servo motor 2 is fixed on the upper left side of the connecting frame 1, and the output end of the servo motor 2 is connected to the shaft of a cleaning roller brush 4 via a pulley 3. The shaft of the cleaning roller brush 4 is mounted on the connecting frame 1 via bearings, and a power rod 11 is installed in the middle of the shaft of the cleaning roller brush 4. An impact block 12 is fixed to one end of the cleaning roller brush 4. The impact block 12 is connected to the cleaning roller brush 4 through a built-in spring 13. The end of the power rod 11 away from the impact block 12 extends out of the rotating shaft on the side of the cleaning roller brush 4. A first magnetic block 14 is embedded in the end of the power rod 11 extending out of the rotating shaft on the side of the cleaning roller brush 4. A second magnetic block 15 is fixed on the side of the first magnetic block 14 and mounted on the connecting frame 1. Rubber bristles are evenly distributed around the circumference of the cleaning roller brush 4. The cleaning roller brush 4 can rotate on the connecting frame 1. The interior of the diverter plate 7 is hollow. The diverter plate 7 is connected to the outside through a negative pressure suction head 8. Multiple negative pressure suction heads 8 are mounted on the diverter plate 7. The longitudinal section of the power rod 11 is T-shaped. The impact block 12 fixed at the end of the power rod 11 is in contact with the interior of the cleaning roller brush 4 in the initial state. The first magnetic block 14 is symmetrically arranged about the transverse central axis of the power rod 11. The magnetism of the first magnetic block 14 is opposite to that of the second magnetic block 15.

[0032] When cleaning of printed materials is required, the connecting frame 1 is installed on the conveyor channel. The servo motor 2 is activated, and the pulley 3 causes the cleaning roller brush 4 to rotate. The rotating cleaning roller brush 4 cleans the surface of the printed materials conveyed on the conveyor channel. Simultaneously, the negative pressure fan 5 is activated during the cleaning process. The activation of the negative pressure fan 5 creates negative pressure at the negative pressure suction head 8 through the flow hose 6 and the diverter plate 7. The negative pressure generated by the negative pressure suction head 8 adsorbs dust generated during the cleaning process. At the same time, the rotation of the cleaning roller brush 4 drives the power rod 11 to rotate synchronously. After the power rod 11 rotates, the first... When the first magnetic block 14 and the second magnetic block 15 approach each other, the magnetic attraction between them can cause the power rod 11 to move towards the outside of the connecting frame 1. When the power rod 11 moves, the impact block 12 can move synchronously. When the power rod 11 rotates with the cleaning roller brush 4, the first magnetic block 14 and the second magnetic block 15 at the end of the power rod 11 move away from each other. The power rod 11 is reset under the action of the built-in spring 13, which can cause the impact block 12 to be reset synchronously. The reset impact block 12 can impact the cleaning roller brush 4. The vibration generated by the impact can shake off the dust attached to the cleaning roller brush 4.

[0033] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. The following technical content is disclosed in this example: a snap-fit ​​side plate 16 is provided on the outer side of the upper end of the power rod 11, and the snap-fit ​​side plate 16 is fixed on the diverter plate 7. A limiting rod 9 fixed on the connecting frame 1 is inserted through the upper end of the diverter plate 7. The diverter plate 7 is connected to the connecting frame 1 through the auxiliary spring 10. The inner wall of the upper end of the diverter plate 7 and the outer wall of the limiting rod 9 are in contact with each other, and the diverter plate 7 can slide on the limiting rod 9.

[0034] When the power rod 11 rotates, the first magnetic block 14 and the second magnetic block 15 at its end approach each other. The magnetic attraction of the first magnetic block 14 and the second magnetic block 15 can make the power rod 11 move towards the outside of the connecting frame 1. After the power rod 11 moves, it can push the snap-fit ​​side plate 16 and the diverter plate 7 to move synchronously. When the first magnetic block 14 and the second magnetic block 15 at the end of the power rod 11 move away from each other, the power rod 11 is reset under the action of the built-in spring 13, and the snap-fit ​​side plate 16 and the diverter plate 7 are reset under the action of the auxiliary spring 10. This can realize the reciprocating movement of the diverter plate 7. The reciprocating movement of the diverter plate 7 can increase the dust collection range of the side negative pressure suction head 8.
