Description

Technical Field

[0001] The present invention relates to the technical field of density board conveying, and more specifically, it relates to a conveying device for density board processing. Background Art

[0002] Density board is a composite board mainly made of wood fiber or other plant fibers. After a fine fiber preparation process and applying synthetic resin, it is pressed under high temperature and high pressure conditions. According to its density, this material can be divided into high-density fiberboard, medium-density fiberboard, and low-density fiberboard, and each category has different physical properties and application scenarios.

[0003] In the process of density board processing, grooving is an important link. By grooving, the bending strength of the density board can be significantly improved, enabling it to more effectively withstand various external loads and pressures, thereby enhancing its structural stability. At the same time, grooving can also add decoration to the density board and improve its appearance to meet diverse design requirements. After the grooving process is completed, the density board needs to be polished to remove surface burrs and improve smoothness, and then output to the coating equipment for subsequent coating processing. Generally, the coating equipment includes a spraying system, a drying system, etc., and these equipment usually need to be set at a specific height to facilitate the smooth connection with the coating process and drying equipment. Therefore, in order to ensure that the polished density board can be smoothly conveyed to the coating equipment, two conveyor belts need to be arranged at different heights.

[0004] However, in the process of switching the density board from one conveyor belt to another, due to insufficient friction between the conveyor belt and the density board, the board may easily slide under the action of gravity or inertia, resulting in axial displacement of the density board. Secondly, the uneven connection between the two conveyor belts will also cause the density board to be impacted during the switching process, resulting in axial displacement of the density board. This displacement may not only cause misalignment of the density board but also increase the risk of jamming with the inner wall of the conveying device, thus affecting the production of the density board and reducing production efficiency. Summary of the Invention

[0005] The present invention provides a conveying device for density board processing, which solves the technical problem in the related art that in the process of switching the density board from one conveyor belt to another, due to insufficient friction between the conveyor belt and the density board, the board may easily slide under the action of gravity or inertia, resulting in axial displacement of the density board.

Detailed implementation manners

[0032] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0033] According to the attached Figure 1 to the attached Figure 3As shown, a conveying device for fiberboard processing includes a first conveying device 100, a second conveying device 200, and a third conveying device 300. Among them, during the production process of fiberboard, the fiberboard needs to go through multiple processing and treatment stages. These stages sometimes need to be carried out at different heights to interface with other equipment or technological processes.

[0034] After grooving the fiberboard, it is necessary to polish the fiberboard and convey the polished fiberboard to a coating device for coating processing. The coating device usually includes a spraying system, a drying system, etc., and needs to be set at a specific height to interface with the coating process and drying equipment. That is to say, in specific implementation, in order to facilitate conveying the polished fiberboard to the coating device for coating processing, the height position of the first conveying device 100 is lower than the height position of the second conveying device 200.

[0035] Among them, the installation height of the first conveying device 100 is lower than the installation height of the second conveying device 200. The third conveying device 300 is arranged between the first conveying device 100 and the second conveying device 200, and is used to convey the fiberboard on the first conveying device 100 to the upper surface of the second conveying device 200, so as to facilitate the second conveying device 200 to convey the fiberboard and facilitate subsequent processing of the fiberboard.

[0036] Specifically, according to the attached Figure 2 As shown, the third conveying device 300 includes a conveying frame 301, and a plurality of conveying rollers 302 are connected by bearings inside the conveying frame 301 for conveying the fiberboard to a designated position. A connecting frame 303 is also installed on the conveying frame 301 for supporting the conveying frame 301, so as to stably convey the fiberboard on the first conveying device 100 to the second conveying device 200.

[0037] According to the attached Figure 4 to the attached Figure 7 As shown, a circulating mechanism 400 is provided inside the conveying frame 301. The circulating mechanism 400 includes a circulating plate 401 arranged between every two conveying rollers 302, and a plurality of rubber rollers 402 are connected by bearings on the circulating plate 401 for jacking up the fiberboard upward, separating the contact between the fiberboard and the conveying rollers 302, so that the air at the bottom of the fiberboard can circulate freely. And, through the setting of the rubber rollers 402, the friction force with the surface of the fiberboard is increased, thus ensuring the stability of the fiberboard during the jacking movement.

[0038] The connection frame 303 is provided with a bearing plate 403 inside, and a plurality of connecting columns 404 are arranged on both sides inside the bearing plate 403. The positions of the connecting columns 404 correspond to the positions of the moving plate 401 one by one, and the connecting columns 404 are fixedly connected to the moving plate 401. Through the arrangement of the bearing plate 403 and the connecting columns 404, the moving plate 401 is stably supported, so as to facilitate driving the moving plate 401 to move up and down. Among them, electric push rods 405 are installed on both sides inside the connection frame 303, and the telescopic ends of the electric push rods 405 are fixedly connected to the bearing plate 403.

[0039] It should be understood that when the electric push rod 405 is driven to perform telescopic movement to jack up the density board upward, the bearing plate 403 moves upward, thereby driving a plurality of moving plates 401 to move synchronously, so as to jack up the density board through the rubber rollers 402, and support the bottom of the density board through the rubber rollers 402, so that air circulation is facilitated at the bottom of the density board.

[0040] During continuous conveying operation, the electric push rod 405 controls the bearing plate 403 to perform telescopic movement, so that the rubber rollers 402 perform cyclic jacking movement, thereby facilitating continuous conveying of the density board.

[0041] Specifically, according to the appendix Figure 7 As shown, a connecting shaft 406 is provided on the bearing plate 403, and supports 407 are rotatably connected to both sides of the outside of the connecting shaft 406 through bearings, and the supports 407 are fixedly connected to the bearing plate 403. Swing arms 408 are installed on both sides of the connecting shaft 406, and a chute 409 is opened inside the swing arms 408. A plurality of slide rods 410 corresponding to the positions of the connecting columns 404 are slidably connected in the chute 409, and the slide rods 410 are fixedly connected to the connecting columns 404. In this embodiment, through the sliding connection of the chute 409 and the slide rod 410, it is convenient for the slide rod 410 to move freely in the chute 409. And, the bearing plate 403 and the connecting columns 404 are slidably connected. When the swing arm 408 rotates, through the limitation of the chute 409 and the slide rod 410, the connecting column 404 is forced to move up and down inside the swing arm 408.

[0042] Among them, according to the appendix Figure 5 As shown, a first spring 413 is provided on the connecting column 404, and both ends of the first spring 413 are fixedly connected to the bearing plate 403 and the connecting column 404 respectively. By using the first spring 413 to assist in supporting the connecting column 404, at the same time, when the first connecting column 404 moves up and down, the first spring 413 generates elastic deformation and has a restoring force, so as to facilitate the reset of the swing arm 408.

[0043] Furthermore, according to the appendix Figure 9 and the appendix Figure 10As shown, the swing arm 408 has two postures, one is the horizontal posture and the other is the inclined posture. When the swing arm 408 is in the inclined posture, one end of the swing arm 408 rotates upward and the other end rotates downward, so that one end of the swing arm 408 is in a low posture and the other end is in a high posture. That is to say, when the slide bar 410 moves in the chute 409, one side of the connecting column 404 on both sides of the swing arm 408 moves upward and the other side moves downward, thereby driving the moving plate 401 to form an inclined plane, so that the rubber roller 402 changes to an inclined posture like the swing arm 408.

[0044] Among them, the horizontal posture is the initial state of the swing arm 408. When the swing arm 408 rotates, the swing arm 408 is in an inclined posture. The included angle between the horizontal posture and the inclined posture of the swing arm 408 is α.

[0045] When α is less than 5°, the vertex height of the rubber roller 402 is greater than the vertex height of the rollers in the second conveying device 200. Although there will be a height difference between the rubber roller 402 and the rollers in the second conveying device 200, it does not affect the normal blanking of the density board.

[0046] When α is equal to 5°, the vertex of the rubber roller 402 and the vertex of the rollers in the second conveying device 200 are on the same horizontal plane, which is convenient for conveying the density board. When the inclination angle is smaller, the blanking fluctuation range of the density board is also smaller, further increasing the stability. Therefore, the included angle range between the horizontal posture and the inclined posture of the swing arm 408 is 0° < α ≤ 5°, and the included angle between the horizontal posture and the inclined posture of the swing arm 408 is preferably 5°.

[0047] On the contrary, when α is greater than 5°, the vertex height of the rubber roller 402 is less than the vertex height of the rollers in the second conveying device 200, which will hinder the blanking of the density board, so that the rollers in the second conveying device 200 form an obstruction to the density board, resulting in the density board being unable to be conveyed.

[0048] Further, according to the attached Figure 5 and the attached Figure 7 As shown, gears 411 are installed at both ends of the connecting shaft 406, and a rack plate 412 is provided above one side of the gear 411. The rack plate 412 is fixedly connected to the outer wall of the conveying frame 301. The rotation angle of the rack plate 412 driving the gear 411 is equal to the included angle α between the horizontal posture and the inclined posture of the swing arm 408. Among them, the rack plate 412 is arranged on the side of the gear 411 close to the second conveying device 200.

[0049] It should be noted that according to the attached Figure 3 and the attached Figure 9As shown, the height between the vertex of the roller and the vertex of the conveying roller 302 in the second conveying device 200 is H1. When the rubber roller 402 is in an inclined posture, the height between the vertex of the lowest rubber roller 402 and the vertex of the conveying roller 302 is H2. Among them, the heights of H1 and H2 are the same. That is to say, when the rubber rollers 402 are arranged in an inclined manner, the vertices of the rubber rollers 402 and the vertices of the rollers in the second conveying device 200 are on the same horizontal plane. When the density board moves on the surface of the rubber roller 402, the density board moved onto the second conveying device 200 is conveyed by the rotation of the rollers in the second conveying device 200.

[0050] According to the attached Figure 3 , the attached Figure 6 and the attached Figure 8 As shown, extraction mechanisms 500 are provided above and below the conveying frame 301. The extraction mechanism 500 includes a first air box 501 arranged above the conveying frame 301. And a suction end 502 is provided on the side of the first air box 501 close to the conveying frame 301, and the suction end 502 is open. Both sides of the first air box 501 are fixedly connected to the conveying frame 301 through mounting frames. Specifically, by means of the open setting, it is convenient to adsorb and recover the dust on the upper surface of the density board, remove the dust on the upper surface of the density board, so as to facilitate the subsequent spraying process.

[0051] A connection end 503 is installed on the side of the first air box 501 away from the suction end 502, and a pipe connection is provided on the connection end 503 for connecting the connection end 503 with an external suction device. In this embodiment, the connection end 503 is communicated with the opening of the suction end 502. When the suction device is connected to extract the dust on the density board, a negative pressure is formed in the first air box 501, and the opening position faces the density board conveying position, so that the dust on the upper surface of the density board can be extracted, making the dust separate from the density board, thereby removing the dust. Among them, the suction device can be a fan, a negative pressure pump, etc., and the air in the first air box 501 is suctioned through the suction device.

[0052] In addition, according to the attached Figure 6 As shown, a shunt pipe 505 is installed on the lower surface of the moving plate 401, and a plurality of second air boxes 506 are installed on the upper surface of the moving plate 401. The inside of the shunt pipe 505 and the second air boxes 506 are connected and communicated. In this embodiment, by arranging the first air box 501 and the second air boxes 506 on the upper and lower sides of the density board, the dust on the top and bottom surfaces of the density board can be suctioned, and the dust on the density board can be separated.

[0053] Moreover, the rubber rollers 402 lift the density board, allowing the air flow to pass through the space between the rubber rollers 402, improving the dust suction effect on the surface of the density board. Secondly, by connecting the air flows inside the first air box 501 and the second air box 506, the dust on both the upper and lower surfaces of the density board can be comprehensively sucked, improving the dust separation effect and separation efficiency.

[0054] Furthermore, according to the attached Figure 8 As shown, on both sides of the connection end 503, there are first connection pipes 504 corresponding to the number of the shunt pipes 505. The second connection pipes 507 are installed on the shunt pipes 505. The first connection pipes 504 and the second connection pipes 507 can be connected by an external hose. Through the hose connection, it is convenient for the moving mechanism 400 to move up and down, preventing interference with the normal operation of the moving mechanism 400 and avoiding movement interference.

[0055] According to the attached Figure 4 and the attached Figure 11 As shown, in order to facilitate the transfer of the density board on the first conveying device 100 to the second conveying device 200, and to avoid offset misalignment when the third conveying device 300 conveys the density board on the first conveying device 100. In this embodiment, on both sides inside the conveying frame 301, there are following mechanisms 600 for assisting in aligning the two sides of the density board, thus avoiding the problem of offset jamming when the second conveying device 200 conveys the density board.

[0056] Among them, the following mechanism 600 includes following plates 601 arranged on both sides inside the conveying frame 301. On the sides of the following plates 601 away from each other, there are inclined blocks 602 installed. On the side of the inclined block 602 away from the following plate 601, there is an inclined plate 603, and a fixing plate 604 is installed on the inclined plate 603. The fixing plate 604 is fixedly connected to the conveying frame 301.

[0057] It should be noted that when the rubber rollers 402 lift the density board upward, the following plates 601 move upward synchronously with the rubber rollers 402. Moreover, as the following plates 601 move upward, the inclined blocks 602 come into contact with the inclined plate 603, and the inclined plate 603 squeezes the inclined blocks 602, causing the following plates 601 to approach each other, thereby pushing the two sides of the density board, and through the cooperation of the two groups of following plates 601, the density board is corrected.

[0058] Furthermore, according to the attached Figure 12As shown, an extension plate 605 is also installed on the inclined plate 603. Moreover, a roller 610 is connected to the inclined block 602 by a bearing. When the rubber roller 402 continuously moves upward, the inclined block 602 also moves upward accordingly. At this time, the inclined block 602 comes into contact with the extension plate 605, and through the arrangement of the roller 610, the resistance between the inclined block 602 and the extension plate 605 is reduced, enabling the follower plate 601 to correct the density board while also assisting in limiting the density board during dust separation on both the upper and lower sides of the density board, thereby improving the scope of application.

[0059] In addition, according to the appendix Figure 12 As shown, a connecting plate 606 is also installed on the follower plate 601, and a groove matching with the conveying roller 302 is formed on the connecting plate 606. Guide grooves 607 are formed on the closer sides of every two circulating plates 401, and a slider 608 is slidably connected in the guide groove 607. The slider 608 is fixedly connected to the connecting plate 606. Through the sliding connection between the guide groove 607 and the slider 608, the smoothness of the movement of the follower plate 601 is further improved. In this embodiment, a second spring 609 is installed between the guide groove 607 and the slider 608. Through the arrangement of the second spring 609, when the inclined plate 603 contacts and limits the inclined block 602, the follower plate 601 can be reset under the action of the elastic restoring force of the second spring 609.

[0060] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
