Description

Technical Field

[0001] The invention relates to the technical field of gluing and bonding devices for paperboard production, in particular to a gluing and bonding device for corrugated paperboard production. Background Art

[0002] Corrugated cardboard is a plate-like material made by gluing face paper and wavy corrugated paper formed by corrugating rollers. It is generally divided into single corrugated cardboard and double corrugated cardboard. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. During the processing of corrugated cardboard, a corrugated cardboard gluing device is required to apply glue on the peaks on both sides of the corrugated core paper so as to bond the corrugated paper base paper and face paper together to form a complete corrugated cardboard.

[0003] In the prior art, when producing corrugated cardboard, two forming rollers are usually used to press the cardboard into a corrugated shape. A glue roller is provided on one side of the forming roller. Glue is applied to one side of the corrugated paper and then compounded. When gluing the other side of the corrugated core paper, the corrugated core paper needs to be re-conveyed to the gluing equipment for gluing, which increases the production process and reduces production efficiency.

[0004] At the same time, when the corrugated core paper is glued again, the formed corrugated core paper may be deformed to a certain extent when it is subjected to pressure, resulting in unstable bonding and uneven shape of the corrugated core paper. Unstable bonding and uneven shape of the corrugated core paper will affect the mechanical properties of the formed corrugated board. Summary of the invention

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A gluing and bonding device for corrugated cardboard production, comprising:

[0007] Gluing mechanism, used for gluing and bonding corrugated cardboard;

[0008] The supporting mechanism is arranged on one side of the corrugated core paper, and comprises a supporting rod for supporting the corrugated core paper;

[0009] A circulation mechanism, connected to the supporting mechanism, for extracting the supporting rods in the corrugated core paper;

[0010] The gluing mechanism comprises a second rubber roller and a second paper feeding roller. The second rubber roller is used to apply glue to the upper end of the corrugated core paper, and the second paper feeding roller is used to transport the upper paper.

[0011] Furthermore, the support mechanism also includes two rotating rollers, two transmission belts are arranged between the two rotating rollers, a plurality of limiting holes are opened in the transmission belts, and the support rods are slidably connected to the limiting holes.

[0012] Furthermore, a rotating wheel is rotatably mounted on one end of the support rod, and the support rod is adapted to the corrugated core paper.

[0013] Furthermore, the circulation mechanism includes two translation plates, the translation plates are in contact with the transmission belt, a movable groove and a bevel groove are provided through the translation plates, the bevel groove is connected to the movable groove, and an opening is provided at one end of the translation plate near the bevel groove.

[0014] Furthermore, an arc-shaped plate is fixedly connected between the two translation plates, an arc-shaped groove 1 is provided in the arc-shaped plate, and an arc-shaped groove 2 is provided on one side surface of the arc-shaped plate.

[0015] Furthermore, the rotating wheel is adapted to the inclined surface groove, and the rotating wheel is adapted to the arc groove 1.

[0016] Furthermore, the support rod is matched with the movable groove, and the support rod is matched with the arc groove.

[0017] Furthermore, the inclined groove is connected to the arc groove 1 through an arc, and the movable groove is connected to the arc groove 2.

[0022] The above embodiments of the present invention can achieve the following beneficial effects:

[0023] 1. The present invention provides a gluing mechanism and a supporting mechanism. When the corrugated core paper is bonded to the bottom paper, the supporting rod is inserted into the corrugated core paper. When the corrugated core paper is bonded to the top paper, the supporting rod plays a role of supporting and limiting the corrugated core paper, so that the corrugated core paper and the top paper are bonded more stably and evenly, so that the corrugated core paper inside the formed corrugated board is more even, so as to effectively improve the stability of the mechanical properties of the corrugated board after forming, and avoid the problem that the shape of the corrugated core paper is uneven due to the deformation caused by the pressure when the corrugated core paper is bonded to the surface paper, which affects the mechanical properties of the corrugated board.

[0024] 2. The present invention sets a circulation mechanism in conjunction with the supporting mechanism. The circulation mechanism can drive the support rod in the formed corrugated cardboard through the inclined groove, so that the support rod is completely disengaged, and the arc groove and another inclined groove are used to re-clamp the support rod into the two limiting holes, so that the support rod can be recycled and reused without manual disengagement and replenishment.

[0038] 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.

[0039] See also Figure 1 - Fig. 9 As shown, a gluing and bonding device for corrugated board production includes a gluing mechanism 1 for generating corrugated core paper 2 and bonding the corrugated core paper 2 with lower paper 3 and upper paper 4, thereby producing formed corrugated board.

[0040] See also Figure 1 The gluing mechanism 1 includes a forming roller 101 and a forming roller 102, which are meshed and connected with each other with a certain gap. When the paperboard passes through the forming roller 101 and the forming roller 102, it is pressed into a corrugated shape, thereby forming a corrugated core paper 2;

[0041] The rubber roller 103 is close to the forming roller 2 102. When the forming roller 2 102 rotates, the crest of one side of the formed corrugated medium paper 2 is brought into contact with the rubber roller 103, so that the glue is applied to the crest, which facilitates the bonding of the corrugated medium paper 2 and the bottom paper 3;

[0042] The paper feeding roller 105 is used to transport the lower paper 3. The paper feeding roller 105 is close to the forming roller 2 102, so that the lower paper 3 contacts the wave crest of the corrugated medium paper 2. The forming roller 2 102 provides pressure, and the paper feeding roller 105 provides support, so that the lower paper 3 and the corrugated medium paper 2 are closely attached to each other, and the bonding effect is good. In addition, when the corrugated medium paper 2 and the lower paper 3 are bonded, the corrugated medium paper 2 is attached to the forming roller 2 102, so that the corrugated medium paper 2 will not be deformed when meshing.

[0043] The second rubber roller 104 is used to apply glue to the other side of the corrugated medium paper 2;

[0044] The second paper feeding roller 106 is used to transport the upper paper 4 so that the upper paper 4 is bonded to the other end peak of the corrugated core paper 2.

[0045] It also includes a supporting mechanism 5 located on one side of the forming roller 2 102, which is used to clamp the supporting rod 504 in the wave crest of the corrugated core paper 2 before the corrugated core paper 2 and the lower paper 3 are bonded together, so as to support the corrugated core paper 2, facilitate the subsequent bonding of the corrugated core paper 2 and the upper paper 4, and avoid deformation and deviation of the corrugated core paper 2 when the corrugated core paper 2 and the upper paper 4 are bonded together.

[0046] The support mechanism 5 is connected to a circulation mechanism 6, which is used to take out the support rod 504 in the corrugated board after the corrugated core paper 2 and the upper paper 4 are bonded, and to reset the taken out support rod 504, so that the support rod 504 can be recycled and reused without manual detachment and replenishment.

[0047] See also Figure 2 - Figure 6 The support mechanism 5 includes a rotating roller 501. The rotating roller 501 is a "T"-shaped structure, which is composed of two discs and a cylinder. There are two rotating rollers 501. The rotating rollers 501 are driven by a motor, so that the rotating rollers 501 rotate. A transmission belt 502 is arranged between the two rotating rollers 501, and the two transmission belts 502 are located on both sides of the forming roller 2 102. A plurality of limiting holes 503 are opened in the transmission belt 502, and the limiting holes 503 are evenly distributed. A support rod 504 is slidably installed between the two transmission belts 502 through the limiting holes 503. The cross-section of the support rod 504 is a triangular structure, and the three corners of the triangle are all arc structures, so that the support rod 504 can be adapted to the corrugated core paper 2, and play a supporting role on the wave crest of the corrugated core paper 2.

[0048] A rotating roller 501 is located at the bottom end of the second forming roller 102, so that when the rotating roller 501 drives the transmission belt 502 to rotate, the support rod 504 can be transported into the interior of the corrugated core paper 2 to support and limit the corrugated core paper 2 to avoid deformation of the corrugated core paper 2 during bonding.

[0049] See also Figure 6 - Fig. 9 A rotating wheel 505 is rotatably mounted on one end of the support rod 504. The rotating wheel 505 is composed of two wheels and a mounting rod. The height of the rotating wheel 505 is higher than the longest height of the support rod 504, so that the rotating wheel 505 can be prevented from passing through the limiting hole 503. The circulation mechanism 6 includes two translation plates 601. The translation plates 601 are fitted with the transmission belt 502. A movable groove 605 and an inclined groove 604 are opened in the translation plates 601. The inclined groove 604 is connected to the movable groove 605.

[0050] The movable groove 605 is a triangular groove, and the hypotenuse of the triangle is the inclined groove 604. The movable groove 605 is adapted to the support rod 504, and the support rod 504 can slide along the movable groove 605. The inclined groove 604 is adapted to the rotating wheel 505, and the depth of the inclined groove 604 is higher than the height of the movable groove 605, so that the wheel of the rotating wheel 505 can be clamped on the inner wall of the connecting part of the inclined groove 604 and the movable groove 605, so that the rotating wheel 505 can move along the inclined groove 604. At the same time, due to the rotation connection between the rotating wheel 505 and the support rod 504, the rotating wheel 505 can rotate freely, so that when the rotating wheel 505 moves along the inclined groove 604, it can be converted from sliding to rolling, which is more convenient and stable.

[0051] An opening 603 is formed at one end of the translation plate 601 close to the inclined groove 604 , and the rotating wheel 505 can enter the inclined groove 604 through the opening 603 , so that the rotating wheel 505 can move along the inclined groove 604 .

[0052] An arc plate 602 is fixedly installed between one end of the two translation plates 601, and an arc groove 1 606 and an arc groove 2 607 are opened in the arc plate 602, and the arc groove 1 606 and the arc groove 2 607 are connected. At the same time, the arc groove 1 606 is connected to the inclined groove 604, and the arc groove 2 607 is connected to the movable groove 605. The connection between the arc groove 1 606 and the inclined groove 604, and the arc groove 2 607 and the movable groove 605 are all arc structures. The arc groove 1 606 and the arc groove 2 607 are both semicircular arcs, and the arc size is consistent with the transmission belt 502, so that the support rod 504 can rotate through the arc groove 1 606 and the arc groove 2 607.

[0053] The rotating wheel 505 can move along the inclined groove 604, thereby driving the support rod 504 to move horizontally along the movable groove 605, and detach from the corrugated medium paper 2 without interfering with the corrugated board. At the same time, the support rod 504 is always clamped inside the limiting hole 503 near the side of the translation plate 601. The support rod 504 then flips along the arc groove 1 606 and enters the lower translation plate 601. The arc groove 2 607 makes the flipping of the support rod 504 more stable. After entering the lower translation plate 601, the rotating wheel 505 continues to move along the inclined groove 604, thereby driving the support rod 504 to move horizontally, so that the support rod 504 is clamped between the two limiting holes 503 again, which is convenient for supporting the wave crest of the corrugated medium paper 2 in the future.

[0054] It should be noted that the present invention is a gluing and bonding device for corrugated cardboard production. When in use, the cardboard passes through the forming roller 101 and the forming roller 2 102, so that the cardboard is pressed to form a wavy corrugated core paper 2. The corrugated core paper 2 continues to move along the forming roller 2 102, and the forming roller 2 102 drives one side of the corrugated core paper 2 to contact the glue roller 1 103, so that the crest of the corrugated core paper 2 is glued. The forming roller 2 102 continues to drive the corrugated core paper 2 with glue to move, so as to contact the bottom paper 3 conveyed by the paper feeding roller 1 105, and the corrugated core paper 2 and the bottom paper 3 are bonded by pressure. Since the corrugated core paper 2 is attached to the forming roller 2 102 during bonding, the corrugated core paper 2 will not be deformed, and the bonding is uniform and stable. After bonding, the single-sided bonded corrugated cardboard is transported by a conveyor belt.

[0055] The motor drives the rotating roller 501 to drive the transmission belt 502 to rotate, thereby driving the support rod 504 to rotate, so that before the corrugated core paper 2 is bonded to the lower paper 3, the support rod 504 is inserted into the inside of the corrugated core paper 2 to support and limit the wave crest on one side of the corrugated core paper 2. At the same time, since the support rod 504 is limited by the limiting hole 503, each wave crest of the corrugated core paper 2 can be supported by the support rod 504, the support rod 504 will not deviate, and the supporting effect is better and more stable.

[0056] The corrugated paper continues to move, so that the other side peak of the corrugated core paper 2 contacts with the second glue roller 104, so that the peak of the corrugated core paper 2 is glued, and the corrugated core paper 2 with glue contacts with the upper paper 4 conveyed by the second paper feeding roller 106, and the corrugated core paper 2 and the upper paper 4 are bonded through the second paper feeding roller 106 and the support rod 504 to form a complete corrugated board.

[0057] The transmission belt 502 continues to move, so that the rotating wheel 505 fits with the inclined groove 604 through the opening 603, and the rotating wheel 505 rotates and moves along the inclined groove 604, thereby driving the support rod 504 to move horizontally and enter the movable groove 605, and finally the support rod 504 is separated from the corrugated medium paper 2, and the rotating wheel 505 enters the arc groove 1 606 along the inclined groove 604, so that when the transmission belt 502 rotates along the rotating roller 501, it drives the support rod 504 to rotate along the arc groove 1 606, so that the rotating wheel 505 enters the lower translation plate 601, so that the rotating wheel 505 continues to move along the inclined groove 604, driving the support rod 504 to move, so that the support rod 504 is re-engaged in the two limiting holes 503, so that the support rod 504 returns to its original position, which is convenient for the reuse of the support rod 504.
