Technical Field

[0001] The invention relates to the technical field of paperboard processing, in particular to a surface cleaning device used before paperboard printing. Background Art

[0002] Since cardboard is made of fiber and filler, it is easy to cause dust to fall off due to high-speed movement of the production line, transfer drop, electrostatic adsorption and mechanical force. Excessive dust will not only affect the color accuracy, clarity, glossiness and flatness of the printed matter, but also cause defects, blurriness and other temperatures in the printed matter. Therefore, the surface cleaning device before cardboard printing is used to clean the dust on the surface of the cardboard before it enters the printing press. The main purpose of this type of device is to remove dust and residual impurities on the surface of the cardboard to ensure printing quality and the normal operation of the printing press.

[0007] As a preferred technical solution of the present invention, guide plates are fixedly connected to both sides of the first conveying frame and the second conveying frame.

[0008] As a preferred technical solution of the present invention, a connecting bracket is fixedly connected to the surface of the glue storage box, and a lower end of the connecting bracket is rotatably connected to a pressing shaft.

[0009] As a preferred technical solution of the present invention, a side guard is fixedly connected to the surface of the second conveying frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the present invention, when the cardboard material is moved between two glue coating wheels, the glue coating wheels roll on both sides of the cardboard material to coat the side edges of the cardboard material with latex, and the first conveyor frame and the second conveyor frame arranged at right angles are used to realize the direction change between the cardboard material and another glue coating mechanism, so that the other two side edges of the cardboard material can be coated with latex. This process can realize coating the four side edges of the cardboard material with latex, sealing the incision of the cardboard material, and preventing the incision from continuously generating dust and falling off in the subsequent mechanical operation and vibration environment.

[0014] 2.

[0015] 3. In the present invention, when the cardboard material passes through the dust removal component, the air flow generated by the dust removal component can accelerate the drying speed of the latex, and after the cardboard material passes through the first dust removal component, the cardboard material can be automatically turned over by the turning frame, and then the second dust removal component can be used to remove dust and clean the other side of the cardboard material, thereby improving the overall cleaning effect of the cardboard material.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-8 The present invention provides a technical solution for a surface cleaning device before cardboard printing:

[0027] according to Figure 1-6 As shown, a surface cleaning device for cardboard before printing comprises a first conveyor frame 1, a second conveyor frame 2, a conveyor belt 3, a cardboard material 4 and two dust removal components 5. The first conveyor frame 1 and the second conveyor frame 2 are arranged at right angles to each other. The two dust removal components 5 are fixedly installed on the surface of the second conveyor frame 2. The first conveyor frame 1 and the second conveyor frame 2 are both provided with a glue coating mechanism, the glue coating mechanism comprises a glue storage box 601 and a glue coating wheel 608. The upper surface of the glue storage box 601 is provided with a glue injection port 613. Side brackets 605 are fixedly installed on both sides of the first conveyor frame 1 and the second conveyor frame 2. The side brackets 605 are fixedly connected to There are base blocks 612, and the glue storage box 601 is fixedly connected to the upper surfaces of the two base blocks 612. The lower surface of the glue storage box 601 is connected to two silicone tubes 611. The lower surfaces of the two base blocks 612 are fixedly connected with glue outlet boxes 606. The lower ends of the two silicone tubes 611 are respectively connected to the two glue outlet boxes 606. The two glue outlet boxes 606 are rotatably inserted with longitudinal shafts 607. One end of the two longitudinal shafts 607 located inside the glue outlet boxes 606 is fixedly connected with glue coating wheels 608. The glue coating wheels 608 roll on both sides of the paperboard material 4 to bring out the latex in the glue outlet boxes 606 and coat it on the side of the paperboard material 4.

[0028] Among them, the upper end of the longitudinal rotating shaft 607 is fixedly connected with the second bevel gear 610, the surface of the base block 612 is welded with a connecting arm 614, the lower end of the connecting arm 614 is rotatably connected with the transverse rotating shaft 615, one end of the transverse rotating shaft 615 is fixedly connected with the first bevel gear 609, the first bevel gear 609 is meshed with the second bevel gear 610, the surface of the transverse rotating shaft 615 is fixedly connected with a rotating frame 616, the cross-sectional shape of the rotating frame 616 is a "cross" shape, and the four arm ends of the rotating frame 616 are rotatably connected with rollers 617, and the rollers 617 roll and crush on the surface of the silicone tube 611, so that the viscous latex in the glue storage box 601 can be quantitatively transported to the glue output box 606 in a band-like manner as needed, and the wear on the silicone tube 611 can be reduced.

[0029] Among them, both sides of the first conveyor frame 1 and the second conveyor frame 2 are fixedly connected with guide plates 603. The cardboard material 4 can be accurately moved between the two glue coating wheels 608 through the guidance of the guide plates 603. The surface of the glue storage box 601 is fixedly connected with a connecting bracket 604. The lower end of the connecting bracket 604 is rotatably connected with a lower pressing shaft 618. The lower pressing shaft 618 will make the middle part of the cardboard material 4 bend downward and the two ends tilt up, which can prevent the glue coating wheel 608 from contacting the conveyor belt 3 during the gluing process, causing the conveyor belt 3 to be sticky with latex. The surface of the second conveyor frame 2 is fixedly connected with a side guard frame 602. The side guard frame 602 can be used to correct the moving trajectory of the cardboard material 4 when it is transferred to the second conveyor frame 2, so that the cardboard material 4 is aligned between the two guide plates 603.

[0030] When in use, the cardboard material 4 is placed on the first conveyor frame 1. Since the first conveyor frame 1 and the second conveyor frame 2 are composed of a conveyor belt 3, a motor and related power transmission components, the cardboard material 4 can be conveyed. This is a common method in the prior art and will not be described in detail here. In the process of conveying the cardboard material 4, the cardboard material 4 can be accurately moved between the two glue coating wheels 608 by the guidance of the guide plate 603. As the cardboard material 4 continues to move, the glue coating wheels 608 with sponge material on the outer ring will roll on both sides of the cardboard material 4, so that the latex in the glue box 606 can be brought out and coated on the side of the cardboard material 4. Then the first conveyor frame 1 drives the cardboard material 4 to continue to move, and the cardboard material 4 can be conveyed to the second conveyor frame 2. The second conveyor frame 2 continues to drive the cardboard material 4 to continue to move to the next glue coating mechanism to repeat the above operation, so that the other two sides of the cardboard material 4 can be coated with latex. This process can achieve the four sides of the cardboard material 4 being coated with latex and the incision of the cardboard material 4 is blocked.

[0031] When the glue coating wheel 608 rotates, the transmission of the power of the first bevel gear 609 and the second bevel gear 610 can drive the rotating frame 616 to rotate, and the roller 617 can roll and crush on the surface of the silicone tube 611, so that the viscous latex in the glue storage box 601 can be quantitatively transported to the glue outlet box 606 in a band-like manner as needed. It is worth noting that the multiple conveyor belts 3 are evenly arranged on the first conveyor frame 1 and the second conveyor frame 2, but there is a large gap between the two conveyor belts 3 located in the middle. Under this condition, when the cardboard material 4 moves on the first conveyor frame 1 and the second conveyor frame 2, it will pass under the lower pressing shaft 618. As the cardboard material 4 continues to move, the lower pressing shaft 618 with the bottom lower than the upper surface of the conveyor belt 3 will cause the middle part of the cardboard material 4 to bend downward and the two ends to be slightly tilted. This can prevent the glue coating wheel 608 from contacting the conveyor belt 3 during the glue coating process, causing the conveyor belt 3 to be stuck with latex, and can achieve the purpose of more comprehensive latex coating on the side of the cardboard material 4.

[0032] according to Figure 2 , Figure 7 and Figure 8 As shown, a bottom bracket 702 is fixedly connected to the lower surface of the second conveying frame 2, and a power motor 703 is fixedly installed at one end of the bottom bracket 702. A short-distance rotating shaft 708 is rotatably connected to the longitudinal arm end of the bottom bracket 702, and both ends of the short-distance rotating shaft 708 are fixedly connected to a turning frame 701. A plurality of card slots 707 adapted to the cardboard material 4 are evenly opened on the surface of the turning frame 701. The cardboard material 4 enters the card slots 707 on the turning frame 701, and then the power motor 703 drives the turning frame 701 to rotate, so that the cardboard material 4 can be automatically turned over, that is, the other side of the cardboard material 4 can be dusted and cleaned by the second dust removal component 5. The output shaft of the power motor 703 is fixedly connected to a transmission rotating shaft 704, and one end of the transmission rotating shaft 704 is fixedly connected to a first gear 705. A second gear 706 is fixedly sleeved on the surface of the short-distance rotating shaft 708, and the first gear 705 is meshed with the second gear 706, so that the power of the power motor 703 can be transmitted, thereby realizing the rotation of the turning frame 701.

[0033] When used specifically, as the cardboard material 4 coated with latex continues to move on the second conveyor frame 2, it will enter the dust removal assembly 5, in which a fan is provided to suck away the dust on the cardboard material 4, which is a common method in the prior art and will not be described in detail here. Since latex is coated on the cardboard material 4, the air flow generated by the dust removal assembly 5 accelerates the drying speed of the latex when passing through the inside of the dust removal assembly 5. Since there is a large gap between the two conveyor belts 3 located in the middle, the turning frame 701 can rotate unimpeded. When the cardboard material 4 passes through the first dust removal assembly 5, it enters the corresponding slot 707 on the turning frame 701, and then the power motor 703 drives the turning frame 701 to rotate, and moves back to the conveyor belt 3 and moves out of the slot 707, so that the cardboard material 4 can be automatically turned over, and then the second dust removal assembly 5 is used to remove dust and clean the other side of the cardboard material 4.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
