Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a dustproof device for a printing machine. Background Art

[0002] With the continuous development of printing technology, printing equipment is more and more widely used in all walks of life. However, in the printing process, since the equipment is usually in an open environment, impurities such as dust and particulate matter in the air are often easily attached to the printing materials, which not only affects the printing quality, but also may cause damage to the printing equipment, causing more trouble to the printing operation. Most of the existing dust removal devices directly absorb the dust on the surface of the printing material. Since the dust adheres to the surface of the printing material and is not easily absorbed, it will cause omissions in the dust removal, reducing the dust removal effect. Therefore, it is necessary to design a dust prevention device for the printing machine. Utility Model Content

[0003] The purpose of the utility model is to provide a dustproof device for a printing press to solve the problems raised in the above background technology.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up the mutual cooperation between the movable frame, the turntable and the clamping plate, the two ends of the printing material can be clamped and fixed by the clamping plate, and the roller can squeeze the connecting rod through the rotation of the turntable, which can drive the movable frame to move up and down. With the action of the vibration spring, the movable frame can vibrate vertically at a high frequency, and the printing material can be driven to vibrate synchronously, so that the dust on the surface of the printing material can be shaken off, avoiding the situation that the dust adheres to the surface of the printing material and is difficult to be sucked out. The dust shaken off the surface of the printing material can be sucked out more conveniently through the second dust suction hood, which can effectively ensure the cleanliness of the printing material and avoid affecting the printing.

[0014] 2. By providing the first dust hood and the dust head to cooperate with each other, the dust head can be extended when the conveying frame moves downward, so that the dust at the bottom of the printed material can be absorbed by the dust head during the vibration of the printed material. It is convenient to perform double-sided dust collection on the printed material without affecting the conveying of the printed material, thereby effectively improving the dust removal effect.

[0033] Embodiment 1

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a dust-proof device for a printing machine proposed by the utility model comprises a printing machine body 1, a dust removal box 2 and a movable frame 7, a dust removal box 2 is fixedly installed on one side of the printing machine body 1, a movable frame 7 is slidably installed on the inner wall of the dust removal box 2, a clamping plate 9 is slidably connected to the front end of the movable frame 7, a connecting rod 702 is fixedly installed between the movable frames 7, a turntable 10 is rotatably installed on the inner wall of the dust removal box 2, a roller 1001 cooperating with the connecting rod 702 is rotatably installed on the outer side of the turntable 10, a conveying frame 6 is movably installed inside the dust removal box 2 between the clamping plates 9, a first dust hood 5 and a second dust hood 8 are fixedly installed in the dust removal box 2 at the top and bottom of the conveying frame 6, respectively, and a dust removal box 3 is fixedly connected to the top of the dust removal box 2;

[0035] The movable frame 7 and the dust removal box 2 are slidably installed through the slide groove 203, and a vibration spring 701 is fixedly connected between the movable frame 7 and the dust removal box 2. A motor 204 is fixedly installed at the rear end of the dust removal box 2, and the output end of the motor 204 is fixedly connected to the turntable 10. The conveying frame 6 and the dust removal box 2 are movably connected through the first driving rod 601. A dust collection head 501 is fixedly installed on the top of the first dust collection hood 5, and the dust collection head 501 extends into the conveying frame 6. The movable frame 7 and the splint 9 are slidably installed through the sliding frame 901, and an anti-slip pad 903 is adhered to the inner side of the splint 9. A second driving rod 902 is fixedly connected between the splint 9 and the movable frame 7. The dust collection box 3 is connected to the first dust collection hood 5 and the second dust collection hood 8 through a dust collection pipe 301. A fan 4 is fixedly installed on the top of the dust removal box 2, and the suction end of the fan 4 is connected to the dust collection box 3.

[0036] The working principle of the dust-proof device of the printing press based on Example 1 is: by introducing the printing material into the dust removal box 2, the printing material can be conveniently transported through the conveying frame 6. The second driving rod 902 and the first driving rod 601 are electric push rods or hydraulic push rods, which can be telescopic. When the printing material is transported into the dust removal box 2, the second driving rod 902 can be used to drive the clamping plate 9 to move up and down, and the two ends of the printing material can be clamped by driving the clamping plate 9 to move together. The first driving rod 601 can be used to contract and move to drive the conveying frame 6 to move downward, so that the conveying frame 6 can be separated from the printing material. By starting the motor 204, the motor 204 can drive the turntable 10 to rotate, and the turntable 10 can drive the roller 1001 to perform a revolution when rotating. When the roller When the wheel 1001 contacts the connecting rod 702, the limiting effect of the roller 1001 on the connecting rod 702 can push the connecting rod 702 to move upward, and the connecting rod 702 can synchronously drive the movable frame 7 to move upward. When the roller 1001 rotates and separates from the connecting rod 702, the elastic effect of the vibration spring 701 can push the movable frame 7 to move downward for reset. Through the rotation of the turntable 10, the roller 1001 can repeatedly push the connecting rod 702 to move, and with the effect of the vibration spring 701, the movable frame 7 can move vertically up and down, which can produce a vibration effect, and can conveniently and synchronously drive the printing material to vibrate at a high frequency, so as to remove dust from the surface of the printing material, avoid the situation where dust adheres to the surface of the printing material and is not easy to be sucked out, and improve the dust removal efficiency.

[0037] By starting the fan 4, the air in the dust box 3 can be sucked out, so that the dust box 3 is in a negative pressure state. Through the dust pipe 301, the second dust hood 8 can generate suction, which can absorb the dust falling off the surface of the printing material, so that the dust can be sucked into the dust box 3 for storage. When the conveying frame 6 moves downward, the dust head 501 can extend out of the conveying frame 6, so that the dust head 501 can absorb the dust at the bottom of the printing material, which can facilitate the double-sided dust collection operation of the printing material, and effectively improve the dust removal effect.

[0040] In this embodiment, Figure 2 As shown, the printing material can be conveniently introduced into the dust removal box 2 through the feed port 201. When the dust removal of the printing material is completed, the first driving rod 601 can be extended and retracted to drive the conveying frame 6 to move upward and can re-contact the printing material. The clamping operation of the printing material can be cancelled by the extension of the second driving rod 902 to drive the clamping plate 9 to expand, so that the printing material can be placed on the conveying frame 6. The conveying frame 6 can be used to convey the printing material to the discharge port 202. The dust-removed printing material can be conveyed to the printing machine body 1 through the discharge port 202 for printing operation. Figure 1 As shown, the dust removal box 2 can be conveniently supported by the mounting frame 101, and the dust removal box 2 can be docked and installed with the printing machine body 1.
