Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of corrugated board production, and particularly relates to a paperboard drying balance ballast device for a corrugated board production line. BACKGROUND

[0002] The paperboard drying balance ballast device is an important component of the corrugated board production line, which plays a role in balancing the load of the corrugated board after the corrugated board is coated with glue by a gluing machine and enters a drying machine at a high speed, so that the adhesion quality between the corrugated boards and the production efficiency are improved in the drying process.

[0003] In the prior art, a pressing plate is usually used to press the corrugated board, and a spring at the top of the pressing plate is used to abut against the pressing plate to ensure that the pressing plate is closely attached to the corrugated board. However, when the pressing plate is used to press the corrugated board, the covering and pressing of the pressing plate will inevitably cause poor air permeability of the corrugated board, so that the moisture in the paperboard is not easy to evaporate, and thus the strength of the corrugated board is reduced and the drying efficiency is reduced. In addition, when the pressing plate faces the high-speed moving corrugated board, the pressing plate will be impacted and lifted up by the uneven protrusions on the surface of the corrugated board. At this time, if the lifting force is too large, the pressing plate will quickly leave the surface of the corrugated board, so that a long pressure load blind area is formed before the pressing roller returns, causing quality defects of the corrugated board pressure load. Therefore, in order to solve the problem, the product needs to be optimized and designed, and it is necessary to provide a paperboard drying balance ballast device for a corrugated board production line.

In addition, the air nozzle is arranged at the bottom of the frame, so that the air pump can be started to blow through the air nozzle in the process of high-speed transmission of the corrugated paper board, so as to apply a certain air pressure to the surface of the corrugated paper board, which can prevent the surface of the corrugated paper board from being raised on both sides of the compression surface of the compression roller, and can also accelerate the moisture on the surface of the corrugated paper board, thereby improving the drying and shaping quality effect.

[0020] Through the above setting, after the glued corrugated paperboard is transmitted, the pressure roller 6 will be extruded on the upper part of the corrugated paperboard, and will be rolled during the transmission of the corrugated paperboard, so that the corrugated paperboard can not be blocked too much and can not be deformed during high-speed transmission. At the same time, since the contact area between the pressure roller 6 and the corrugated paperboard is very small, the pressure holding effect can be ensured without affecting the moisture evaporation of the corrugated paperboard. In addition, since the air nozzles 7 are arranged at the bottom of the frame box 2, the air pump 8 can be started to blow through the air nozzles 7 during high-speed transmission of the corrugated paperboard, so as to apply a certain air pressure to the surface of the corrugated paperboard. On the one hand, it prevents the surface of the corrugated paperboard from being raised on both sides of the pressure surface of the pressure roller 6, and on the other hand, it can accelerate the moisture evaporation of the surface of the corrugated paperboard, thereby improving the drying and shaping quality effect.

[0021] Referring to Figure 1 , 2 , 3, a piston cylinder 9 is fixedly installed on the inner side of the top end of the side plate 3, a movable rod 10 fixedly connected with the sliding block 4 is insertedly installed at the bottom of the piston cylinder 9, a flow divider 11 is fixedly connected to the top end of the piston cylinder 9 through a rigid pipeline, a nitrogen cylinder 12 is fixedly connected to the bottom of the flow divider 11, a piston 13 fixedly connected with the inserted end of the movable rod 10 is slidingly installed in the inner part of the piston cylinder 9, a sliding plug 14 is slidingly installed in the inner part of the nitrogen cylinder 12, the inner part of the piston cylinder 9 above the piston 13 and the inner part of the nitrogen cylinder 12 above the sliding plug 14 are filled with hydraulic oil, the inner part of the nitrogen cylinder 12 below the sliding plug 14 is filled with nitrogen, a partition plate 15 is fixedly installed in the inner part of the flow divider 11, a flow pipe 16 is installed through the outer periphery of the partition plate 15, a sealing plug 17 is fixedly connected to the bottom of the flow pipe 16 through a spring, and the sealing plug 17 abuts against the inner cavity bottom of the flow divider 11, flow channels 18 for communicating the inner cavities of the piston cylinder 9 and the nitrogen cylinder 12 are formed in the inner sides of the flow divider 11.

[0022] By the above design, during the high-speed transmission of the corrugated board, due to the fact that the surface of the corrugated board is not completely flat, the pressure roller 6 may be lifted up, once the pressure roller 6 is extruded by the corrugated board and moves upward, the side frame 5 will drive the movable rod 10 above the sliding block 4 to be inserted into the piston cylinder 9, at this time, the piston 13 moves upward, the hydraulic oil in the piston cylinder 9 is discharged into the flow divider 11 through the pipeline, and then is discharged into the nitrogen cylinder 12 from the flow channel 18, so that the sliding plug 14 in the nitrogen cylinder 12 moves downward to compress the nitrogen in the nitrogen cylinder 12 to release the extrusion force on the movable rod 10, so as to prevent the pressure roller 6 from extruding the corrugated board too much and causing deformation, during this process, the bottom of the partition plate 15 is extruded on the bottom of the inner cavity of the flow divider 11 through the spring connected sealing plug 17;

[0023] The channel in the middle of the flow divider 11 is closed, and then when the hydraulic oil passes through the flow divider 11 from top to bottom into the nitrogen cylinder 12, it can only pass through the flow channel 18, thereby damping and decelerating the flow of the hydraulic oil, and the pressure of the nitrogen in the nitrogen cylinder 12 increases more and more in the later stage of compression, so that the movable rod 10 does not move upward suddenly, but moves upward slowly to consume most of the insertion force from the movable rod 10, thereby damping and decelerating the upward movement of the pressure roller 6, so that the pressure roller 6 does not move away from the corrugated board suddenly, and when the pressure roller 6 returns to the original position, the hydraulic oil in the nitrogen cylinder 12 is bounced back by the nitrogen to return to the original chamber, at this time, the hydraulic oil passing through the flow divider 11 from bottom to top will extrude the sealing plug 17 to compress the spring and move upward, so as to open the channel in the middle of the flow divider 11, so that the returned hydraulic oil can quickly return through the flow channel 18 and the flow pipe 16, thereby reducing the damping of the movable rod 10 when it returns, so that the pressure roller 6 quickly returns to contact the corrugated board, thereby reducing the contact time of the pressure roller 6 on the surface of the corrugated board, and improving the quality of the pressure.

[0024] The implementation principle of the embodiment of the present application is:

[0025] Firstly, after the glued corrugated board is transmitted, the pressure roller 6 will extrude on the upper part of the corrugated board, and will roll in contact with the corrugated board during the transmission of the corrugated board, so that the corrugated board will not be blocked too much and will not be deformed during high-speed transmission, and at the same time, due to the fact that the contact area between the pressure roller 6 and the corrugated board is very small, the pressure roller 6 can ensure the pressure holding effect without affecting the moisture evaporation of the corrugated board, and in addition, due to the fact that the bottom of the frame 2 is provided with the air nozzle 7, the air pump 8 can be started to blow through the air nozzle 7 during the high-speed transmission of the corrugated board, so as to apply a certain air pressure on the surface of the corrugated board, which can prevent the surface of the corrugated board on both sides of the pressure surface of the pressure roller 6 from being lifted up, and can also accelerate the evaporation of the moisture on the surface of the corrugated board, thereby improving the drying and shaping quality effect.

[0026] And, in the process of corrugated paper high-speed transmission, due to the corrugated paper surface is not completely flat, at this time part of the press roller 6 may be lifted, once the press roller 6 is extruded by the corrugated paper and moves up, will drive the side frame 5 extrusion slider 4 above the movable rod 10 into the piston cylinder 9, at this time the piston 13 moves up will the hydraulic oil in the piston cylinder 9 through the pipeline into the flow divider 11, and from the flow channel 18 into the nitrogen cylinder 12, so that the slide plug 14 in the nitrogen cylinder 12 moves down to compress the nitrogen in the nitrogen cylinder 12 to release the extrusion force of the movable rod 10, to prevent the press roller 6 to corrugated paper extrusion caused by deformation, in this process, due to the partition plate 15 bottom through the spring connected sealing plug 17 extrusion in the inner cavity of the flow divider 11 bottom, so that the flow divider 11 middle channel is closed, and then cause the hydraulic oil from top to bottom through the flow divider 11 into the nitrogen cylinder 12 can only pass through the flow channel 18 one way, so as to dampen the flow of hydraulic oil deceleration, with the nitrogen in the nitrogen cylinder 12 in the later stage of compression pressure increases, so that the movable rod 10 will not move up suddenly, but slow down to move up to consume the most from the movable rod 10 plug-in force, so as to dampen the press roller 6 moves up deceleration, so that the press roller 6 will not suddenly leave the corrugated paper, plus when the press roller 6 returns to the original position, the hydraulic oil in the nitrogen cylinder 12 is bounced by the nitrogen and returns to the original chamber, at this time from bottom to top through the flow divider 11 of the hydraulic oil will extrude the sealing plug 17 compression spring moves up, to open the flow divider 11 middle channel, so that the return of the hydraulic oil can pass through the flow channel 18 and flow pipe 16 two kinds of flow channel fast return, to reduce the damping of the movable rod 10 when returning, so that the press roller 6 fast return and corrugated paper contact, so as to reduce the contact time of the press roller 6 from the surface of the corrugated paper, to improve the quality of ballast.
