DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figures 1 to 9 The present invention provides a technical solution: an automatic alignment and correction device for corrugated board production, comprising two groups of conveying rollers 1 arranged on a single-facer and used for conveying base paper and a glue box for receiving glue, wherein a glue roller 2 for applying glue to corrugated paper is arranged in the glue box, and further comprising a steel frame for supporting the conveying rollers 1 and the glue roller 2 and a camera module arranged on the steel frame, wherein the steel frame is provided with a correction structure for adjusting the overlap between the base paper and the corrugated paper; The deviation correction structure includes two groups of claw-shaped frames 3 fixedly connected to the steel frame and respectively used to support a group of conveying rollers 1. The two groups of claw-shaped frames 3 are provided with twisting balls 5 that can rotate freely in the vertical direction, and the conveying rollers 1 rotate synchronously with the twisting balls 5. The claw-shaped frames 3 are also provided with a circumferential component for adjusting the direction of the conveying rollers 1 at multiple angles. The circumferential assembly includes a panning assembly for adjusting the horizontal inclination angle of the conveying roller 1 and a pitching assembly for adjusting the pitch angle of the conveying roller 1; The glue box is fixedly connected with a base plate 18, on which two groups of arc-shaped sealing plates 22 are provided to contact with the outer peripheral surface of the rubber roller 2, and the base plate 18 is provided with two groups of variable distance components for independently adjusting the horizontal position of a single group of arc-shaped sealing plates 22 to change the contact position between the outer peripheral surface of the rubber roller 2 and the glue.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, when making corrugated paperboard, the corrugated paper and the base paper are overlapped by a single-facer, and glue is applied to the corrugated paper by a continuously rotating glue roller 2 to ensure that the two can be bonded together. When conveying the base paper, two sets of conveying rollers 1 turning in opposite directions are driven to convey the base paper to the area where the corrugated paper is bonded, and the conveying position of the base paper when it is close to the corrugated paper is monitored by a camera module. When there is a deviation between the corrugated paper and the base paper, the position of the base paper is corrected by a correction structure to ensure that there is no misalignment when the corrugated paper and the base paper are bonded.

[0021] When correcting the horizontal position of the base paper, when the misalignment distance between the corrugated paper and the base paper is large, the two groups of conveying rollers 1 are driven to deflect synchronously in the horizontal direction through the swing assembly, and then the conveying rollers 1 are driven to form a certain angle with the width direction of the base paper feed. When the conveying rollers 1 rotate, an oblique component force is generated on the base paper, so that the base paper automatically moves laterally during the forward conveying process. The deflection direction of the conveying rollers 1 is adapted to the misalignment direction of the base paper and the corrugated paper, so as to ensure that the corrugated paper and the base paper can be driven to overlap at the adhesion position after the conveying rollers 1 swing horizontally at a certain angle.

[0022] At the same time, when the offset distance between the corrugated paper and the base paper is small, the pitch angles of the two groups of rubber rollers 2 are adjusted by the longitudinal swing assembly, that is, the two groups of conveying rollers 1 are driven to swing a certain angle in the vertical direction. When the pitch angle of the conveying roller 1 changes, the contact angle between the conveying roller 1 and the base paper will change. For the base paper, when the conveying roller 1 is tilted, the contact point between the base paper and the conveying roller 1 will generate a horizontal component force, and this component force will push the base paper to move in the opposite direction of the tilt, thereby achieving the purpose of adjusting the horizontal position of the base paper.

[0023] In detail, the pitch angle adjustment of the conveyor roller 1 will affect the friction between the bottom paper and the conveyor roller 1. For the bottom paper, when the conveyor roller 1 is tilted, the contact area and pressure distribution between the bottom paper and the conveyor roller 1 will change, which will change the friction between the two. The change in friction will affect the stability and movement trend of the bottom paper during the conveying process, thereby affecting the horizontal position of the bottom paper.

[0024] In actual use, if the horizontal deviation between the base paper and the corrugated paper is too large, the horizontal swing component and the vertical swing component can be used together to ensure that the base paper can overlap with the corrugated paper at the bonding position, thereby further increasing the correction range of the base paper position and improving the processing quality of the corrugated cardboard.

[0025] Among them, with the tile paper as a reference, the position of the bottom paper is adjusted according to the horizontal position of the tile paper to ensure that the bottom paper can overlap with the tile paper when it is transported to the adhesion position, thereby avoiding the problem of misalignment. At the same time, in actual use, since the tile paper is used as a reference, when glue is applied on the tile paper, the glue will not fully cover the cross section of the tile paper, but the coating width is slightly smaller than the width of the tile paper. Then, in the process of bonding the bottom paper and the tile paper, the position of the bottom paper is adjusted according to the position of the tile paper. When the position of the bottom paper changes, the adhesion area of ​​the glue on the glue roller 2 is changed by the variable pitch component to ensure that there will be no glue overflow from the edge of the paper after the bottom paper and the tile paper are bonded, thereby avoiding the problems of bubbling, pit jumping or reverse corrugation caused by the glue adhering to the corrugated roller used to transport the tile paper, thereby ensuring the processing quality of the corrugated board.

[0026] In one of the more preferred embodiments, the circumferential assembly includes a horizontal shaft groove 6 and a vertical shaft groove 14 which are opened on the torsion ball 5 and arranged in a cross pattern, and an arc-shaped drive seat 4 is slidably connected to the horizontal shaft groove 6, and the arc-shaped drive seat 4 is driven by a No. 1 motor and rotates on a fixed axis on the claw-shaped frame 3; The longitudinal shaft groove 14 is slidably connected with an arc-shaped driven seat 7 , and the arc-shaped driven seat 7 is fixedly connected with a connecting column 8 , and the connecting column 8 and the conveying roller 1 are coaxially fixed.

[0027] The horizontal swing assembly includes a vertically arranged inner arc plate 10, to which a vertical shaft 9 is fixedly connected, and the vertical shaft 9 is fixedly rotated on the claw-shaped frame 3, and an inner arc through groove 11 is provided on the inner arc plate 10 for the connecting column 8 to slide through; The longitudinal swing assembly includes a horizontally arranged outer arc plate 12, the end of which is fixedly rotated on the torsion ball 5, the outer arc plate 12 and the inner arc plate 10 are arranged overlapping, and an outer arc groove 13 is opened on the outer arc plate 12 for the connecting column 8 to slide through.

[0028] A set of transmission wheels 17 are coaxially fixed on the outer arc plates 12 in the two sets of longitudinal swing assemblies, and a belt for transmission is provided between the two sets of transmission wheels 17; A driven gear 15 is fixedly rotated on the claw-shaped frame 3, and the vertical shafts 9 in the two sets of horizontal swing assemblies are coaxially fixed on the driven gear 15. The driven gear 15 is meshedly connected with a driving gear 16 driven by the second motor and freely rotated in the horizontal direction. The driving gear 16 is fixedly rotated on the claw-shaped frame 3.

[0029] like Figure 1-Figure 4 As shown, when adjusting the horizontal inclination angle of the conveying roller 1, the driving gear 16 is driven by the motor to rotate in the horizontal direction, thereby driving the driven gear 15 meshing with the driving gear 16 to rotate in the horizontal direction, wherein the driven gear 15 is coaxially fixed between the vertical shaft 9 and the inner arc plate 10, so when the driving gear 16 rotates, the inner arc plate 10 can be driven to rotate synchronously, wherein the connecting column 8 arranged on the arc driven seat 7 passes through the inner arc plate 10 through the inner arc groove 11 and contacts the side wall of the inner arc groove 11, and the arc driven seat 7 is slidably arranged on the torsion ball 5 through the longitudinal shaft groove 14, therefore, when the inner arc plate 10 deflects in the horizontal direction, the torsion ball 5 can be driven to deflect synchronously, thereby driving the arc driving seat 4 to slide on the horizontal shaft groove 6, and at the same time, the horizontal inclination angle of the rubber roller 2 can be changed through the arc driven seat 7 and the connecting column 8, thereby driving the conveying roller 1 to form a certain angle with the paper feeding width direction of the base paper, so as to change the horizontal position of the base paper in the bonding area.

[0030] At the same time, when the two sets of transmission wheels 17 are driven to rotate synchronously by another motor, the outer arc plates 12 arranged on the two sets of claw-shaped frames 3 can be driven to swing synchronously in the vertical direction. Since the connecting column 8 passes through the outer arc plate 12 through the outer arc groove 13 and slides with the side wall of the outer arc groove 13, when the outer arc plate 12 swings, the pitch angle of the conveying roller 1 can be changed through the connecting column 8, thereby changing the contact angle between the conveying roller 1 and the bottom paper, so that the contact point between the bottom paper and the conveying roller 1 generates a horizontal component force, and this component force will push the bottom paper to move in the opposite direction of the tilt, thereby achieving the purpose of adjusting the horizontal position of the bottom paper, so as to prevent the problem of misalignment between the bottom paper and the tile paper during the bonding process.

[0031] It should be noted that no matter how the inner arc plate 10 and the outer arc plate 12 swing, since the arc driving seat 4 is slidably connected to the torsion ball 5 through the horizontal shaft groove 6, when the arc driving seat 4 rotates freely under the external drive rotation, it can drive the torsion ball 5 to rotate synchronously with it, and drive the conveying roller 1 to rotate synchronously through the arc driven seat 7 and the connecting column 8, and then in the process of the two groups of conveying rollers 1 continuously conveying the base paper, it can drive the horizontal swing component or the vertical swing component to operate to achieve different degrees of deviation correction of the base paper, so as to achieve the purpose of non-stop correction, thereby improving the production efficiency of corrugated cardboard.

[0032] On the basis of the embodiment of the circumferential assembly, the pitch-changing assembly comprises a traverse seat 20 arranged on a base plate 18, and a rectangular groove for horizontal sliding of the traverse seat 20 is provided on the base plate 18, and a position adjustment seat 21 is provided on the traverse seat 20 and a groove body 1 for horizontal sliding of the position adjustment seat 21 is provided, and the position adjustment seat 21 and the arc-shaped sealing plate 22 are fixedly connected; The adjusting seats 21 in the two sets of the variable distance components move synchronously in the same direction in the horizontal direction.

[0033] The traverse seat 20 is provided with a V-shaped rod 23, and the middle part of the V-shaped rod 23 is fixedly rotated on the traverse seat 20, and one end of the V-shaped rod 23 facing the adjustment seat 21 is fixedly connected with a positioning pin 24, and the adjustment seat 21 is provided with a positioning groove 25 for the positioning pin 24 to be slidably connected; The base plate 18 is fixedly connected to a side plate 19, on which a horizontal rod 28 that can move freely in the horizontal direction is provided, and the side plate 19 is provided with a groove body 2 for the horizontal rod 28 to be slidably connected, and a positioning pin 26 is fixedly connected to one end of the V-shaped rod 23 facing the horizontal rod 28, and the horizontal rod 28 is provided with a positioning groove 27 for the positioning pin 26 to be slidably connected.

[0034] The side plate 19 is provided with a horizontal lever 30 which is free to deflect in the horizontal direction. The middle part of the horizontal lever 30 is fixedly rotated on the side plate 19 and is connected to a group of transmission wheels 17. The side of the transverse rod 28 facing the horizontal lever 30 is fixedly connected to a limiting pin 29 , and the horizontal lever 30 is provided with a limiting groove 31 for the limiting pin 29 to be slidably connected.

[0035] like Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when the transmission wheel 17 rotates and drives the outer arc plate 12 to swing in the vertical direction and thus change the pitch angle of the conveying roller 1, it can drive the horizontal lever 30 connected to it to swing synchronously in the horizontal direction, wherein the limit pin 29 fixedly arranged on the transverse rod 28 in the two sets of variable pitch assemblies is slidably connected to the horizontal lever 30 through the limit groove 31. Therefore, when the horizontal lever 30 swings horizontally, the limit pin 29 can drive the two sets of transverse rods 28 to move in opposite directions.

[0036] At the same time, when the lateral rod 28 moves under the drive of the horizontal lever 30, it can drive the V-shaped rod 23 to swing a certain angle in the horizontal direction through the positioning groove 27 provided thereon, and the rotation center point of the V-shaped rod 23 is located on the traverse seat 20, and then when the V-shaped rod 23 swings, the horizontal position of the co-location pin 24 provided at its end changes, thereby driving the relative displacement between the adjustment seat 21 and the traverse seat 20.

[0037] The horizontal rods 28 in the two sets of variable pitch assemblies move in opposite directions, and the two sets of variable pitch assemblies are symmetrically arranged, thereby driving the V-shaped rods 23 in the two sets of variable pitch assemblies to deflect in opposite directions, so that the adjustment seats 21 in the two sets of variable pitch assemblies move in the same direction, wherein the arc-shaped sealing plate 22 is fixedly arranged on the adjustment seat 21, and the two sets of arc-shaped sealing plates 22 move in the same direction, thereby changing the contact area position of the rubber roller 2 and the glue, so that the area is adapted to the correction direction of the base paper, so that while correcting the position of the base paper so that it can overlap with the tile paper at the bonding position, the rubber roller 2 can coat the tile paper to prevent glue leakage from the edge of the paper, thereby further ensuring the processing quality.

[0038] On the basis of the pitch-changing assembly embodiment, a central gear 33 is provided on the base plate 18, which is freely rotatable in the horizontal direction and is transmission-connected to the driving gear 16. The central gear 33 is fixedly rotated on the base plate 18 and meshed with a rack 32. The rack 32 is fixedly connected to the traverse seats 20 in the two sets of pitch-changing assemblies. The base plate 18 is provided with a slot body 3 for the two sets of racks 32 to slide horizontally.

[0039] like Figure 2 and Figure 5 As shown, when the driving gear 16 rotates, it can drive the central gear 33 connected to it to rotate synchronously, and during the rotation of the central gear 33, it can drive the rack 32 meshing with it to move in the horizontal direction, and the rack 32 is fixedly connected to the traverse seat 20 in the two sets of variable pitch assemblies. When the two sets of traverse seats 20 move synchronously in the same direction, the horizontal positions of the V-shaped rods 23 and the adjustment seats 21 thereon can be changed, thereby driving the two sets of arc-shaped sealing plates 22 to move synchronously in the same direction.

[0040] It should be noted that the transmission wheel 17 and the horizontal lever 30 as well as the driving gear 16 and the center gear 33 are all connected by transmission. In actual use, combined transmission can be performed through the meshing relationship between the sprocket and the coupling and multiple sets of bevel gears to ensure that the transmission wheel 17 can rotate synchronously with the horizontal lever 30, and synchronously ensure the synchronous rotation between the driving gear 16 and the center gear 33.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
