Description

Technical Field

[0001] The utility model relates to the technical field of corrugated board processing, in particular to a suction dust removal device for a corrugated board production line. Background Art

[0002] The corrugated board production line, abbreviated as the corrugating line, is a key production device for corrugated box production enterprises. The corrugated board production line is the most important production line equipment in carton packaging enterprises, including several important components such as wet-end equipment, dry-end equipment, and production management systems.

[0003] Chinese Patent Publication No. CN114734720A, published on July 12, 2022, discloses a corrugated board printing mechanism and production line, including a bracket and a printing machine arranged on the bracket. One end of a fixing plate is rotatably provided with an elastic rod. It also includes two parallel plates that are slidably arranged, and the sliding directions of the two parallel plates are perpendicular to the conveying direction of the conveyor belt. When the corrugated paper is flattened by the printing equipment and passes through the parallel plates, the elastic rod drives the two parallel plates to move towards each other through the driving of the transmission component to squeeze the corrugated paper and straighten the corrugated paper.

[0004] In a corrugated board production line such as the above, the wet-end equipment includes a printing mechanism. During the process of the cardboard being transferred to the printing mechanism by the transfer component on the production line, a certain amount of dust will inevitably adhere to the printing surface. When the amount of this dust is relatively large, it is likely to affect the printing effect of the subsequent cardboard. Therefore, it is necessary to effectively and quickly handle the dust, so there is an urgent need to propose a suction dust removal device for a corrugated board production line to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a suction dust removal device for a corrugated board production line in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A suction dust removal device for a corrugated board production line includes a support frame and a mounting seat. The support frame is in a U-shaped structure. The mounting seat is arranged on the outer surface of the vertical end of the support frame. The bottom of the horizontal end of the support frame is rotatably connected to a vertical plate. A push plate is fixedly installed at the bottom of the vertical plate. A connecting plate is fixedly installed on the outer surface of the horizontal end of the support frame. A suction pump and a water tank are fixedly installed on the top of the connecting plate. The output end of the suction pump is communicated with the water tank, and a dust suction component for sucking dust is arranged at the input end of the suction pump.

[0008] Preferably, the cross-section of the vertical end of the support frame is in a T-shaped structure. The vertical end of the support frame is slidably connected to the inner wall of the mounting seat through a vertically arranged chute, and a positioning portion for positioning the support frame is provided on the inner wall of the mounting seat.

[0009] Preferably, the positioning portion includes a locking rod. The outer wall of the locking rod is screwed to the inner wall of the mounting seat, and the open end of the locking rod abuts against the outer wall of the vertical end of the support frame.

[0010] Preferably, the vertical plate and the push plate are distributed in a T shape. A dust-removing sleeve is wrapped around the bottom of the push plate, and the dust-removing sleeve is made of polytetrafluoroethylene.

[0011] Preferably, the dust suction assembly includes a cloth air pipe. The cloth air pipe is fixedly connected to the input end of the air suction pump, and a plurality of dust extraction pipes are connected in parallel at the bottom of the cloth air pipe.

[0012] Preferably, a fixing frame is fixedly installed on the outer wall of the connecting plate, and the bottom of the vertical end of the fixing frame is fixedly connected to the cloth air pipe.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the overall air suction and dust removal device is erected above the conveying assembly. During the process that the cardboard is transferred to the printing mechanism along with the conveyor belt of the conveying device, the cardboard will contact the scraping plate. At this time, since the friction force between the cardboard and the conveyor belt is greater than the total gravity of the push plate and the vertical plate, the cardboard will push the push plate. The push plate will be in an inclined state and lean on the upper side of the cardboard. As the cardboard moves, the bottom of the push plate will concentrate and push away the attached dust. At the same time, the input end of the air extraction pump will cause reverse air flow to flow inside the cloth air pipe and the plurality of dust extraction pipes. The plurality of dust extraction pipes will extract the dust until the dust is transferred into the water tank, thereby realizing the dust removal of the cardboard and avoiding the influence of dust on the printing effect of the cardboard.

[0015] 2. In this application, rotate the locking rod so that its open end disengages from the outer wall of the vertical end of the support frame. At this time, the support frame loses its restraint force, and the entire support frame can be vertically moved. The support frame drives the connecting plate until the push plate reaches the specified height, and then tighten the locking rod so that the open end of the locking rod closely adheres to the outer wall of the vertical end of the support frame, thereby realizing the re-positioning of the support frame through friction force, and enabling the height of the push plate to be synchronously adjusted according to the thickness of the cardboard.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] An air suction and dust removal device for a corrugated cardboard production line includes a support frame 1 and a mounting seat 2. The support frame 1 has a U-shaped structure. The mounting seat 2 is arranged on the outer wall of the vertical end of the support frame 1. The bottom of the horizontal end of the support frame 1 is rotatably connected to a vertical plate 6. The bottom of the vertical plate 6 is fixedly installed with a push plate 4. The outer wall of the horizontal end of the support frame 1 is fixedly installed with a connecting plate 9. The top of the connecting plate 9 is fixedly installed with an air suction pump 11 and a water tank 10. The output end of the air suction pump 11 is communicated with the water tank 10, and a dust suction component for sucking dust is arranged at the input end of the air suction pump 11;

[0025] The overall air suction and dust removal device is erected above the conveying component. During the process of the cardboard being transferred to the printing mechanism along with the conveyor belt of the conveying device, the cardboard will contact the push plate 4. At this time, since the friction between the cardboard and the conveyor belt is greater than the overall gravity of the push plate 4 and the vertical plate 6, the cardboard will push the push plate 4. The push plate 4 will be in an inclined state and lean on the top of the cardboard. As the cardboard moves, the bottom of the push plate 4 will centrally push away the dust attached to the top of the cardboard. At the same time, the input end of the air suction pump 11 will cause a reverse air flow to flow inside the air distribution pipe 7 and multiple dust extraction pipes 8. The multiple dust extraction pipes 8 will suck away the dust until the dust is transferred into the water tank 10, thereby realizing the dust removal of the cardboard and avoiding the influence of dust on the printing effect of the cardboard.

[0026] Specifically, asFigure 2 and Figure 4 As shown in , the cross-section of the vertical end of the support frame 1 is a T-shaped structure, so as to avoid the support frame 1 and the mounting seat 2 from being completely separated. The vertical end of the support frame 1 is slidably connected to the inner surface wall of the mounting seat 2 through a vertically arranged slide groove 13, and the inner surface wall of the mounting seat 2 is provided with a positioning part for positioning the support frame 1, and the positioning part includes a locking rod 3, the outer wall of the locking rod 3 is screwed and connected with the inner surface wall of the mounting seat 2, and the open end of the locking rod 3 abuts against the outer wall of the vertical end of the support frame 1, and the locking rod 3 is rotated to make its open end detach from the outer wall of the vertical end of the support frame 1. At this time, the support frame 1 loses its restraining force, and the support frame 1 can be moved vertically as a whole. The support frame 1 is linked to the connecting plate 9 until the push plate 4 reaches the specified height, and then the locking rod 3 is tightened so that the open end of the locking rod 3 is tightly attached to the outer wall of the vertical end of the support frame 1, so that the support frame 1 is re-positioned through friction, so that the height of the push plate 4 can be synchronously adjusted according to the thickness of the cardboard.

[0027] Specifically, such as Figure 2 and Figure 3 As shown in , the vertical plate 6 and the push plate 4 are distributed in a T shape, ensuring the overall weight of the two. The bottom of the push plate 4 is wrapped with a dust cover 5, which is made of polytetrafluoroethylene. Polytetrafluoroethylene is a polymer material with excellent high temperature resistance and anti-sticking properties, which can prevent dust from adhering to the push plate 4. The dust collection component includes an air distribution pipe 7, which is fixedly connected to the input end of the suction pump 11, and multiple groups of dust extraction pipes 8 are connected in parallel at the bottom of the air distribution pipe 7. The input end of the suction pump 11 will cause the air distribution pipe 7 and the multiple groups of dust extraction pipes 8 to generate reverse airflow inside. The multiple groups of dust extraction pipes 8 will extract the dust until the dust is transferred to the inside of the water tank 10. A fixing frame 12 is fixedly installed on the outer wall of the connecting plate 9, and the bottom of the vertical end of the fixing frame 12 is fixedly connected to the air distribution pipe 7, thereby ensuring the stable position of the air distribution pipe 7.

[0028] Working principle: The overall air suction and dust removal device is installed above the conveying component. During the process that the cardboard follows the conveyor belt of the conveying device and is transferred to the printing mechanism, the cardboard will contact the push plate 4. At this time, since the frictional force between the cardboard and the conveyor belt is greater than the overall gravity of the push plate 4 and the vertical plate 6, the cardboard will push the push plate 4. The push plate 4 will be in an inclined state and lean on the top of the cardboard. As the cardboard moves, the bottom of the push plate 4 will centrally push away the dust attached to the top of the cardboard. At the same time, the input end of the air suction pump 11 will cause a reverse air flow to flow inside the cloth air pipe 7 and the multiple dust extraction pipes 8. The multiple dust extraction pipes 8 will extract the dust until the dust is transferred into the water tank 10, thereby realizing the dust removal of the cardboard and avoiding the influence of dust on the printing effect of the cardboard. Rotate the locking rod 3 so that its open end disengages from the outer wall of the vertical end of the support frame 1. At this time, the support frame 1 loses its restraint force, and the whole support frame 1 can be vertically moved. The support frame 1 is linked to the connecting plate 9. Until the push plate 4 reaches the specified height, then tighten the locking rod 3 so that the open end of the locking rod 3 closely adheres to the outer wall of the vertical end of the support frame 1, thereby realizing the repositioning of the support frame 1 through the frictional force, and thus enabling the height of the push plate 4 to be synchronously adjusted according to the thickness of the cardboard.

[0029] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
