Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corrugated cardboard production equipment, specifically relating to a corrugated paper gluing mechanism. Background Technology
[0002] In the production practice of gluing machines on corrugated cardboard production lines, to laminate single-wall corrugated paper and linerboard into three- or five-layer cardboard, a gluing roller rotates, carrying glue. A cylinder presses down a pressure roller, bringing the corrugated paper closer to the gluing roller, allowing the glue to be evenly applied to the tips of the corrugations, thus completing the gluing process. When the equipment stops, the pressure roller is lifted by a cylinder to prevent the single-wall corrugated paper from sticking to the gluing roller and becoming soaked in glue. When restarting the machine, the corrugated paper will break, causing a stop. Therefore, the pressure roller needs to be automatically lifted when stopping the machine to prevent the corrugated paper from breaking. When the machine stops, the pressure rollers lift up. Because the pressure rollers are not powered, when they suddenly stop rotating from a speed of 500-600 rpm, the internal stress of the steel material, the weight of the rollers themselves, and thermal expansion and contraction will cause deformation in the stationary state. When the machine is restarted, the rotating pressure rollers may bounce, affecting the bonding effect of the corrugated paper and causing poor bonding such as bubbling. Therefore, to avoid the shortcomings of the existing technology, it is necessary to improve it. Utility Model Content
[0003] The purpose of this invention is to provide a corrugated paper gluing mechanism that can keep the pressure rollers rotating slowly when the gluing machine on the corrugated board production line is stopped, thereby avoiding deformation caused by stress under heat conditions due to the sudden stop of the pressure rollers and improving the quality of corrugated board production.

[0005] A corrugated paper gluing mechanism includes a gluing wheel, a frame, a first rocker arm, a paper pressing wheel, and a rotation device. The lower end of the gluing wheel is immersed in a glue tank. The gluing wheel is driven to rotate by a motor. The frame is positioned above the gluing wheel. The first rocker arm is rotatably mounted on the frame. The paper pressing wheel is rotatably mounted on the first rocker arm and can swing and adhere to the gluing wheel with the first rocker arm. The rotation device includes a first cylinder seat, a rotation cylinder, a rotation rocker arm, and a one-way bearing. The cylinder seat is rotatably mounted on the first rocker arm. The self-rotating cylinder is mounted on the first cylinder seat. The self-rotating rocker arm is rotatably mounted on the first rocker arm. The output end of the self-rotating cylinder is rotatably connected to the self-rotating rocker arm and can drive the self-rotating rocker arm to swing. The one-way bearing is mounted on the self-rotating rocker arm. The rotating shaft of the paper pressing wheel is inserted into the one-way bearing. The locking direction of the one-way bearing is opposite to the working rotation direction of the paper pressing wheel. The rotation direction of the paper pressing wheel driven by the self-rotating rocker arm is consistent with the locking direction.
[0006] As a preferred embodiment of the above-mentioned corrugated paper gluing mechanism, a first transmission rod is provided between the output end of the rotating cylinder and the rotating rocker arm. One end of the first transmission rod is rotatably connected to the output end of the rotating cylinder, and the other end of the first transmission rod is rotatably connected to the swing arm end of the rotating rocker arm.
[0007] As a preferred embodiment of the above-mentioned corrugated paper gluing mechanism, a rocker arm shaft is provided between the first rocker arm and the frame, one end of the rocker arm shaft is rotatably connected to the frame, and the other end of the rocker arm shaft is rotatably connected to the first rocker arm.
[0008] As a preferred embodiment of the above-mentioned corrugated paper gluing mechanism, a second cylinder seat is rotatably provided on the frame, and a drive cylinder is fixedly installed on the second cylinder seat. The output end of the drive cylinder is rotatably connected to the swing arm end of the first rocker arm and can drive the first rocker arm to swing.
[0009] As a preferred embodiment of the above-mentioned corrugated paper gluing mechanism, a second transmission rod is provided between the driving cylinder and the first rocker arm. One end of the second transmission rod is rotatably connected to the output end of the driving cylinder, and the other end of the second transmission rod is rotatably connected to the swing arm end of the first rocker arm.
[0010] As a preferred embodiment of the above-mentioned corrugated paper gluing mechanism, a paper feeding guide wheel is rotatably mounted on one end of the first rocker arm, and the tangential direction of the paper feeding guide wheel is parallel to the tangential direction of the gluing wheel.
[0011] As a preferred embodiment of the above-mentioned corrugated paper gluing mechanism, a paper output guide wheel is rotatably mounted on the other end of the first rocker arm, and the tangential direction of the paper output guide wheel is parallel to the tangential direction of the gluing wheel.
[0012] The corrugated paper gluing mechanism provided by this utility model has the following advantages compared with the prior art:
[0013] The lower end of the gluing roller in this invention is immersed in a gluing tank. The gluing roller is driven to rotate by a motor, thus adhering gluing to its surface for the gluing process in corrugated paper production. A first rocker arm is rotatably mounted on the frame, and a pressure roller can swing with the first rocker arm and adhere to the gluing roller. During corrugated paper production, the rotation of the gluing roller causes the corrugated paper to move tangentially to the rotation of the gluing roller. The pressure roller adheres to the gluing roller, and the corrugated paper passes between the gluing roller and the pressure roller. Due to friction, the rotation of the gluing roller, through the corrugated paper, drives the pressure roller to rotate as well. Therefore, the pressure roller can hold the corrugated paper down without affecting its movement. The pressure roller holds the corrugated paper, ensuring more thorough gluing as it passes over the gluing roller. When the machine stops, to prevent the corrugated paper from pressing against the gluing roller... When the upper part of the paper presser is wetted, the first rocker arm lifts up, driving the pressure roller away from the upper paste roller. At this time, due to the high temperature generated during the production process, the internal stress of the steel material of the pressure roller itself, the influence of the roller's own weight, and thermal expansion and contraction, the pressure roller is prone to deformation. Therefore, when the machine stops, the self-rotation device starts, the self-rotation cylinder extends, and the output end of the self-rotation cylinder is rotatably connected to the self-rotation rocker arm, which can drive the self-rotation rocker arm to swing, thereby causing the pressure roller to rotate slowly. After the stroke is completed, the self-rotation cylinder retracts. Because the self-rotation rocker arm is equipped with a one-way bearing, the pressure roller will not be driven to reverse when the self-rotation cylinder retracts. The self-rotation cylinder retracts and immediately extends again. This action is repeated continuously, so that the pressure roller rotates slowly and evenly, avoiding the production of defective corrugated cardboard due to deformation of the pressure roller when it is stationary, and improving the quality of corrugated cardboard production.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0025] Please refer to the following: Figures 1 to 4 The corrugated paper pasting mechanism provided in the embodiments of this utility model will now be described.
[0026] like Figures 1 to 4As shown, the corrugated paper gluing mechanism of this utility model includes a gluing wheel 200, a frame 400, a first rocker arm 300, a paper pressing wheel 500, and a rotation device 600. The lower end of the gluing wheel 200 is immersed in the glue tank 100. The gluing wheel 200 is driven to rotate by a motor. The frame 400 is disposed above the gluing wheel 200. The first rocker arm 300 is rotatably mounted on the frame 400. The paper pressing wheel 500 is rotatably mounted on the first rocker arm 300. The paper pressing wheel 500 can swing and adhere to the gluing wheel 200 with the first rocker arm 300. The rotation device 600 includes a first cylinder seat 610, a rotation cylinder 620, a rotation rocker arm 630, and a one-way valve. A bearing 631 is provided. The first cylinder seat 610 is rotatably mounted on the first rocker arm 300. The rotating cylinder 620 is mounted on the first cylinder seat 610. The rotating rocker arm 630 is rotatably mounted on the first rocker arm 300. The output end of the rotating cylinder 620 is rotatably connected to the rotating rocker arm 630 and can drive the rotating rocker arm 630 to swing. The one-way bearing 631 is mounted on the rotating rocker arm 630. The rotating shaft of the paper pressing wheel 500 is inserted into the one-way bearing 631. The locking direction of the one-way bearing 631 is opposite to the working rotation direction of the paper pressing wheel 500. The rotating rocker arm 630 drives the paper pressing wheel 500 to rotate in the same direction as the locking direction.
[0027] The locking direction of the one-way bearing 631 is opposite to the working rotation direction of the pressure roller 500, which ensures that the pressure roller 500 will not be stuck by the one-way bearing 631 and cannot work normally when it is working normally. The rotation direction of the pressure roller 500 driven by the self-rotating rocker arm 630 is consistent with the locking direction, which ensures that when the self-rotating cylinder 620 is extended, the transmission effect can be achieved through the locking of the self-rotating rocker arm 630 and the one-way bearing 631, and the pressure roller 500 is driven to rotate when the self-rotating cylinder 620 is extended.
[0028] One-way bearing 631 is a special type of bearing that allows the shaft to rotate freely in only one direction, while locking in the opposite direction. Its core function is to achieve unidirectional transmission through an internal mechanical structure, and it is widely used in mechanical systems that require prevention of reverse rotation or control of the direction of power transmission. One-way bearing 631 is existing technology and will not be described in detail here.
[0029] It is understandable that during the gluing process of corrugated paper, when the machine stops, the pressure roller 500 will continue to rotate due to inertia due to the loss of power, but it will soon stop rotating. At this time, the pressure roller 500, which has generated high temperature during operation, has not completely cooled down. After stopping rotation, due to the influence of the internal stress of the steel material of the pressure roller 500 itself, the influence of the roller's own weight, and thermal expansion and contraction, the pressure roller 500 will deform in the static state. When the machine is restarted, the pressure roller 500 may jump when it rotates, which will affect the bonding effect of the corrugated paper and cause poor bonding such as bubbling of the cardboard. After the machine stops, the self-rotating device 600 drives the pressure roller 500 to continue rotating slowly through the extension and retraction of the self-rotating cylinder 620 and the swinging motion of the self-rotating arm. The one-way bearing 631 ensures that the pressure roller 500 will not be driven to reverse when the self-rotating cylinder 620 retracts, and can continue to push the pressure roller 500 to rotate when the self-rotating cylinder 620 extends, thus achieving the effect of keeping the pressure roller 500 rotating slowly.
[0030] It should be noted that when the self-rotating cylinder 620 retracts, the pressure roller 500 will not be driven to reverse. Moreover, because the self-rotating cylinder 620 drives the pressure roller 500 to rotate when it extends, the pressure roller 500 will continue to rotate slowly due to inertia during the retraction of the self-rotating cylinder 620, and will not stop and start rotating intermittently.
[0031] For example, a first transmission rod 640 is provided between the output end of the rotating cylinder 620 and the rotating rocker arm 630. One end of the first transmission rod 640 is rotatably connected to the output end of the rotating cylinder 620, and the other end of the first transmission rod 640 is rotatably connected to the swing arm end of the rotating rocker arm 630. Through the first transmission rod 640, the telescopic motion of the rotating cylinder 620 is converted into the reciprocating rotational motion of the rotating rocker arm 630, thereby driving the paper pressing roller 500 to rotate. Driving the paper pressing roller 500 to rotate via the rotating cylinder 620, the first transmission rod 640, and the rotating rocker arm 630 achieves a smaller footprint, lower cost, and adaptability to the humid environment of the corrugated paper gluing process compared to driving the paper pressing roller 500 by a motor.
[0032] For example, a rocker arm shaft 330 is provided between the first rocker arm 300 and the frame 400. One end of the rocker arm shaft 330 is rotatably connected to the frame 400, and the other end is rotatably connected to the first rocker arm 300. The first rocker arm 300 rotates around the rocker arm shaft 330 provided on the frame 400, thereby pressing the paper pressing roller 500 against the paste roller 200, pressing the corrugated paper so that the corrugated paper is more fully pasted.
[0033] For example, a second cylinder seat 320 is rotatably mounted on the frame 400, and a drive cylinder 310 is fixedly mounted on the second cylinder seat 320. The output end of the drive cylinder 310 is rotatably connected to the swing arm end of the first rocker arm 300 and can drive the first rocker arm 300 to swing. The first rocker arm 300 is driven by the drive cylinder 310. During production, the first rocker arm 300 is pulled, causing the first rocker arm 300 to rotate around the rocker arm shaft 330 and press the paper pressing roller 500 against the upper paste roller 200. When the machine stops, the drive cylinder 310 extends, driving the first rocker arm 300 to lift, causing the paper pressing roller 500 to leave the upper paste roller 200. The reciprocating swing of the first rocker arm 300 is driven by the drive cylinder 310.
[0034] For example, a second transmission rod 340 is provided between the drive cylinder 310 and the first rocker arm 300. One end of the second transmission rod 340 is rotatably connected to the output end of the drive cylinder 310, and the other end of the second transmission rod 340 is rotatably connected to the swing arm end of the first rocker arm 300. Through the second transmission rod 340, the telescopic motion of the drive cylinder 310 is converted into the reciprocating rotational motion of the first rocker arm 300, thereby achieving the effect of driving the first rocker arm 300 to swing back and forth.
[0035] For example, one end of the first rocker arm 300 is rotatably mounted with a paper feed guide wheel 700, the tangential direction of which is parallel to the tangential direction of the upper paste wheel 200. Figure 1 As shown, when the corrugated paper 110 is fed, it can move along the tangential direction of the feed guide wheel 700 to the surface of the upper paste wheel 200 under the guidance of the feed guide wheel 700. The tangential direction of the feed guide wheel 700 is parallel to the tangential direction of the upper paste wheel 200, which ensures that the corrugated paper 110 can be guided to the surface of the upper paste wheel 200 by the rotation of the feed guide wheel 700.
[0036] For example, a paper output guide wheel 800 is rotatably mounted on the other end of the first rocker arm 300, and the tangential direction of the paper output guide wheel 800 is parallel to the tangential direction of the upper paste wheel 200. Figure 1 As shown, when the corrugated paper 110 completes the paste application process and exits the paper, it can move along the tangential direction of the paste application wheel 200 to the surface of the feed guide wheel 700 under the guidance of the paper exit guide wheel 800, thus completing the paper exit process. The tangential direction of the paper exit guide wheel 800 is parallel to the tangential direction of the paste application wheel 200, ensuring that the corrugated paper 110 moves from the surface of the paste application wheel 200 to the surface of the paper exit guide wheel 800 under the rotation of the paper exit guide wheel 800 to complete the paper exit process.
[0037] The corrugated paper gluing mechanism provided by this utility model has the following advantages compared with the prior art:
[0038] In this invention, the lower end of the gluing roller 200 is immersed in the gluing tank 100. The gluing roller 200 is driven to rotate by a motor, thereby adhering gluing to its surface for the gluing process in corrugated paper production. The first rocker arm 300 is rotatably mounted on the frame 400, and the paper pressing roller 500 can swing with the first rocker arm 300 and be attached to the gluing roller 200. During corrugated paper production, the rotation of the gluing roller 200 drives the corrugated paper to move in the tangential direction of the rotation of the gluing roller 200. The corrugated paper 110 is attached to the upper paste roller 200, passing between the upper paste roller 200 and the pressure roller 500. Due to friction, the rotation of the upper paste roller 200 drives the pressure roller 500 to rotate along with the corrugated paper 110. Therefore, the pressure roller 500 can hold the corrugated paper 110 down without affecting its movement. The pressure roller 500 holds the corrugated paper 110 down, allowing it to be more thoroughly coated with paste as it passes over the upper paste roller 200. When the machine stops, to avoid the corrugated paper... Paper 110 is wetted while resting against the upper paste roller 200. The first rocker arm 300 is raised, driving the pressure roller 500 away from the upper paste roller 200. At this time, due to the high temperature generated during the production process, the internal stress of the steel material of the pressure roller 500, the weight of the roller itself, and thermal expansion and contraction, the pressure roller 500 is prone to deformation. Therefore, when the machine stops, the self-rotation device 600 is started, the self-rotation cylinder 620 extends, and the output end of the self-rotation cylinder 620 is rotatably connected to the self-rotation rocker arm 630 and can drive... The rotating rocker arm 630 swings, causing the pressure roller 500 to rotate slowly. After the travel is complete, the rotating cylinder 620 retracts. Because the rotating rocker arm 630 is equipped with a one-way bearing 631, the pressure roller 500 will not be driven to reverse when the rotating cylinder 620 retracts. The rotating cylinder 620 immediately extends again after retracting. This action is repeated continuously, so that the pressure roller 500 rotates slowly and uniformly. This avoids the production of defective corrugated cardboard due to deformation of the pressure roller 500 when it is stationary, thus improving the quality of corrugated cardboard production.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
