Description

Technical Field

[0001] The utility model relates to the technical field of a spray powder collecting device for a four-color printing press, in particular to a spray powder collecting device for a four-color printing press. Background Art

[0002] The powder collection device of a four-color printing press is usually called a powder adsorption system or a powder collection system. In the four-color printing process, the powder system is used to spray powder on the printed paper to increase the adhesion of the ink and enhance the printing effect. However, such a powder spraying process will also generate a large amount of dust. This powder collection device can effectively collect and control the dust generated during the powder spraying process, reduce the impact on the environment and operators, and keep the printing press running clean and stable.

[0003] For example, the Chinese patent publication: CN217391867U discloses a powder collection device for a four-color printing machine, including a mounting seat, a collection bin is mounted on one side of the top of the mounting seat, and one side of the collection bin is connected to an air inlet pipe, and the side of the collection bin away from the air inlet pipe is connected to an air outlet pipe, a filter plate is passed through the side of the air outlet pipe close to the collection bin, and a filter plate is mounted on the side of the top of the mounting seat away from the air inlet pipe. The utility model is provided with a mounting plate and a cleaning brush on the outside of a mounting rod, a U-shaped plate is respectively connected to the mounting bin and the collection bin for sliding, and a U-shaped plate is connected to a reciprocating screw rod by a thread, so that an operator controls the motor to drive the reciprocating screw rod to rotate, and the U-shaped plate and the mounting rod can drive the mounting plate and the cleaning brush to continuously scrape and clean the filter plate, thereby ensuring its smoothness, and further ensuring the continuous use of the device, and facilitating the operator to quickly disassemble and assemble the mounting plate and the cleaning brush, thereby ensuring its scraping and cleaning effect.

[0004] Although the filter plate can be scraped and cleaned by using the above devices in combination, only scraping the surface of the filter plate with a reciprocating cleaning brush can only scrape off the powder on the surface of the filter plate, and the powder blocking the inner wall of the filter plate mesh is not easy to be cleaned, which will also affect the circulation of airflow.

[0005] Therefore, we propose a powder collecting device for a four-color printing press. Utility Model Content

[0007] The knocking assembly comprises a mounting block, a transmission plate and a knocking head. The mounting block is fixedly mounted on the top of the cleaning wipe, the transmission plate is rotatably mounted on the inner wall of the mounting block, and the knocking head is fixedly mounted on the outer wall of the transmission plate.

[0008] Preferably, the inner wall of the printer body is rotatably connected to a reciprocating screw, one end of the reciprocating screw extends out of the outer wall of the printer body and is fixedly connected to a driving motor.

[0013] Preferably, a torsion spring is fixedly mounted on the outer wall of the rotating shaft, and the other end of the torsion spring is fixedly connected to the inner wall of the mounting block.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model drives the reciprocating screw rod to rotate through a driving motor, so that the cleaning wipe cleans the filter plate and at the same time reciprocates to energize and de-energize the electromagnet. With the cooperation of the torsion spring, the transmission plate can be reciprocated on the inner wall of the mounting block, and at the same time, the knocking head can be driven to knock the surface of the filter plate reciprocally, which can effectively shake off the powder retained in the mesh holes of the filter plate and effectively improve the effect of airflow passing.

One end of the transmission plate 12 and the knocking head 15 are located on the outer wall of the mounting block 10. When the transmission plate 12 is subjected to a force, the knocking head 15 can be driven to knock on the filter plate 9, so that the powder placed inside the mesh of the filter plate 9 can be shaken off. The transmission plate 12 needs to have a certain elasticity.

[0026] See also Figure 1-4 In the figure, the inner wall of the printer body 1 is rotatably connected to a reciprocating screw rod 6, one end of the reciprocating screw rod 6 extends out of the outer wall of the printer body 1 and is fixedly connected to a driving motor 3.

[0027] In this embodiment: a force can be applied to the reciprocating screw 6 to make it rotate on the inner wall of the printer body 1. The drive motor 3 is fixedly installed on the side wall of the printer body 1. The reciprocating screw 6 can be driven to rotate by starting the drive motor 3. The model of the drive motor 3 can be replaced according to the needs of technical personnel in this field, and it will not be elaborated here.

[0028] See also Figure 1-4 In the figure, the outer wall of the reciprocating screw rod 6 is connected with the inner wall of the cleaning wipe 8 by means of internal and external threads.

[0029] In this embodiment: when the reciprocating screw 6 rotates, it can drive the cleaning wipe 8 to slide back and forth on the outer wall of the reciprocating screw 6, and at the same time drive the mounting block 10 to slide, and through the setting of the tapping component, the filter plate 9 can be continuously tapped when the mounting block 10 slides.

[0030] See also Figure 1-4 In the figure, a guide rod 7 is fixedly mounted on the inner wall of the printer body 1 , and the inner wall of the cleaning wipe 8 is slidably fitted with the outer wall of the guide rod 7 .

[0031] In this embodiment, the guide rod 7 is provided to limit the sliding track of the cleaning wipe 8 so that the cleaning wipe 8 can slide smoothly under the rotation of the reciprocating screw rod 6 .

[0032] See also Figure 1-4 In the figure, the transmission plate 12 is set as a magnet, and the inner wall of the mounting block 10 is fixedly mounted with an electromagnet 11.

[0033] In this embodiment: by energizing the electromagnet 11, the transmission plate 12 can be adsorbed, and at this time the transmission plate 12 will rotate and tilt, and at the same time drive the knocking head 15 to knock on the surface of the filter plate 9, and by reciprocatingly energizing and deenergizing the electromagnet 11, the transmission plate 12 can be made to swing back and forth, and at the same time drive the knocking head 15 to knock on the surface of the filter plate 9.

[0034] See also Figure 1-4 In the figure, a rotating shaft 13 is fixedly mounted on the side wall of the transmission plate 12 , and one end of the rotating shaft 13 extends to the inner wall of the mounting block 10 .

[0035] In this embodiment, two rotating shafts 13 are provided, and the two rotating shafts 13 are arranged on both sides of the transmission plate 12. The two rotating shafts 13 extend to the inner wall of the mounting block 10. When the transmission plate 12 is subjected to a force, the rotating shafts 13 are driven to rotate on the inner wall of the mounting block 10.

[0037] In this embodiment: a torsion spring 14 is provided to apply a force to the rotating shaft 13 so that the transmission plate 12 always remains in a vertical state. When the electromagnet 11 adsorbs the transmission plate 12, the transmission plate 12 tilts and the torsion spring 14 deforms to store elastic potential energy until the electromagnet 11 is powered off and the adsorption of the transmission plate 12 is released. At this time, the torsion spring 14 can reset the transmission plate 12 by releasing the elastic potential energy.

[0038] Working principle: By starting the driving motor 3, the reciprocating screw rod 6 is driven to rotate, so that the cleaning wipe 8 cleans the filter plate 9, and at the same time, the electromagnet 11 is energized and de-energized. With the cooperation of the torsion spring 14, the transmission plate 12 can be reciprocated on the inner wall of the mounting block 10, and at the same time, the knocking head 15 is driven to knock the surface of the filter plate 9 back and forth, which can effectively shake off the powder retained in the mesh of the filter plate 9, and effectively improve the effect of airflow.
