Description

Technical Field

[0001] The invention relates to the technical field of corrugated paperboard production, and in particular to a high-wear-resistant and high-strength flexible laminating device. Background Art

[0002] Corrugated paperboard is made of face paper and corrugated paper bonded together by paste. Depending on the required structural strength of the corrugated paperboard, the number of layers of corrugated paper can be set to different levels. After a layer of face paper and a layer of corrugated paper are bonded together by paste to form a single layer of corrugated paper, several layers of single-layer corrugated paper are bonded together by paste to form a whole. After the single-facer heats a layer of flat corrugated paper to press out the required flute shape, paste is applied on the corrugated wave flange and then pressed with the face paper (flat paper) to form a single layer of corrugated paper.

[0003] Figure 1 The figure shows a corrugated board production laminating machine in the prior art (from bottom to top, lower corrugated roller A, upper corrugated roller B and upper pressure roller C), which performs single-point line laminating on the upper corrugated paper and the bottom paper by means of the upper pressure roller and the upper corrugated roller (the single-point line laminating is formed by the top circle R angle of the upper pressure roller and the upper corrugated roller tooth profile, and the general top circle R angle length is 1-1.5mm). The hard line pressure of the single-point line may cause the bottom paper and the corrugated paper to crush and break the paper fibers, resulting in serious physical property degradation. In addition, the corrugated board production laminating machine cannot guarantee the heating time and laminating area. In the process of laminating the corrugated paper and the bottom paper, the penetration and curing time of the paste is short, and it cannot be evenly pressed, resulting in poor laminating quality.

[0004] In order to solve this problem, the present application discloses a highly wear-resistant and high-strength flexible laminating device. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention discloses a highly wear-resistant and high-strength flexible laminating device.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a highly wear-resistant and high-strength flexible laminating device, comprising: a support seat;

[0007] An arc-shaped seat, the arc-shaped seat is arranged below the supporting seat;

[0009] A plurality of arc-shaped scale-type pressing pieces are arranged in a straight line at the bottom of the arc-shaped seat;

[0010] A plurality of elastic connection mechanisms are arranged in a straight line between the arc seat and the support seat and are respectively connected with a plurality of arc-shaped scale-type pressing sheets.

[0016] Further preferably, a pressure relief gauge passing through the support seat is provided above the airbag.

[0017] It is further preferred that the length of the middle arc-shaped scale-like pressing sheet is greater than the lengths of the corresponding arc-shaped scale-like pressing sheets on both sides.

[0018] It is further preferred that rounded corners are provided on both sides of the arc-shaped scale-type pressing sheet in the width direction.

[0019] The present invention achieves the following beneficial effects:

[0020] The present application replaces the upper pressure roller of the traditional corrugated board production press with a high-wear-resistant and high-strength flexible laminating device, which can cooperate with low-temperature and low-pressure steam to realize flexible lamination of the pasted corrugated paper and the bottom paper, avoiding the crushing of the corrugated paper and the bottom paper caused by single-point line hard pressure lamination under high-temperature and high-pressure steam, and maintaining the physical properties of the base paper. The high-wear-resistant and high-strength flexible laminating device of the present application can also form a large-angle, multi-point line flexible package between the single-sided corrugated board and the upper corrugated roller, which not only greatly increases the heating time and the laminating area, but also prolongs the transfer, penetration and curing time of the paste during the laminating process by several times, ensuring good lamination and uniform pressure, further reducing the heat source temperature, and reducing the fiber degradation and damage of the bottom paper and the corrugated paper.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] Example

[0032] To solve Figure 1 The corrugated board production press shown in the figure has a series of problems in the single-point line pressing of the superimposed corrugated paper and the bottom paper, refer to Figure 2-Figure 4 As shown, the present application discloses a highly wear-resistant and high-strength flexible laminating device, comprising: a support seat 10;

[0033] The arc seat 20 is arranged below the support seat 10;

[0034] Two lifting drive mechanisms 30, the two lifting drive mechanisms 30 are relatively arranged above both sides of the support base 10 in the length direction, and the driving parts of the two lifting drive mechanisms 30 are connected to the arc-shaped base 20;

[0035] A plurality of arc-shaped scale-type pressing sheets 40, which are arranged in a straight line at the bottom of the arc-shaped seat 20;

[0036] A plurality of elastic connection mechanisms 50 are arranged in a straight line between the arc seat 20 and the support seat 10 and are respectively connected to a plurality of arc scale-type pressing sheets 40 .

[0037] First, according to the thickness requirements of the corrugated paperboard to be produced, the two lifting drive mechanisms 30 are controlled to move synchronously to move the arc seat 20 up and down;

[0038] When the flexible pressing mechanism is implemented, the pasted corrugated paper and the bottom paper enter between the arc-shaped scale-type pressing sheet 40 and the upper corrugated roller. During this process, the bottom paper will pass through the entire arc surface of the arc-shaped scale-type pressing sheet 40. When the arc-shaped scale-type pressing sheet 40 cooperates with the elastic connecting mechanism 50 to press the corrugated paper and the bottom paper, elastic lifting and lowering can occur, thereby ensuring flexible pressing between the corrugated paper and the bottom paper, avoiding the crushing of the corrugated paper and the bottom paper caused by single-point line hard pressing under high-temperature and high-pressure steam, maintaining the physical properties of the base paper, and also allowing the single-sided corrugated board to form a large-angle, multi-point line flexible package with the upper corrugated roller B, which not only greatly increases the heating time and pressing area, but also makes the laminating process extend the transfer, penetration and curing time of the paste by several times, ensuring good lamination and uniform pressure, further reducing the heat source temperature, and reducing the fiber degradation and damage of the bottom paper and the corrugated paper.

[0039] refer to Figure 5 As shown, in order to install the above-mentioned flexible pressing mechanism with the pressing machine for corrugated cardboard production, the present application respectively opens a plurality of waist-shaped holes 11 on both sides of the length direction of the support base 10. During the specific installation, a plurality of bolts are locked into the two side panels of the pressing machine for corrugated cardboard production (the original pressing machine for corrugated cardboard production, not shown in the present application) through the corresponding waist-shaped holes 11 on both sides of the support base 10.

[0040] refer to Figure 2 and Figure 3As shown, the lifting drive mechanism 30 of the present application includes a screw stepper motor 31 arranged above the support seat 10, and the screw shaft 311 of the screw stepper motor 31 passes through the support seat 10 and is connected to the arc seat 20. When the screw stepper motor 31 drives the screw shaft 311 to rotate, the arc seat 20 of the present application can be adjusted up and down, which can meet the production of corrugated cardboard of various thicknesses and has high practicality.

[0041] refer to Figure 4 As shown, the present application has a groove body 21 opened at the bottom of the support seat 10 in its length direction, and a plurality of arc-shaped scale-type pressing sheets 40 are arranged in a straight line in the groove body 21. The purpose of this scheme is to position the plurality of arc-shaped scale-type pressing sheets 40 to avoid position displacement during operation, thereby ensuring the pressing quality of the bottom paper and the corrugated paper.

[0042] refer to Figure 3 As shown, the elastic connection mechanism 50 of the present application includes an airbag 51 arranged between the arc seat 20 and the support seat 10 and a spring 52 connected to the bottom of the airbag 51 and passing through the support seat 10 to be connected to the arc scale-type pressing plate 40. In addition, the present application provides an inflation port 511 and a pressure relief valve 512 on one side of the width direction of the airbag 51, and a pressure relief gauge 513 passing through the support seat 10 is provided above the airbag 51. In specific implementation, the operator can inflate the middle airbag 51 and / or the airbags 51 on both sides of the middle airbag 51 in sequence according to the width of the corrugated cardboard to be produced. When the airbag 51 is deflated, the pressure relief valve 512 on the corresponding airbag 51 is opened to let the gas flow out, and when the air pressure displayed by the corresponding pressure relief gauge 513 is lower than the set value, it means that the deflation is completed.

[0043] In the present application, the airbag 51 and the spring 52 cooperate to enable the arc-shaped scale-type pressing sheet 40 to achieve elastic lifting and lowering, thereby ensuring uniform squeezing of the paste between the corrugated paper and the bottom paper.

[0044] It should be noted here that no matter how wide the corrugated cardboard is, the middle airbag 51 of the present application must be inflated. In addition, whether the inflation of other airbags 51 is controlled according to the width of the corrugated cardboard can reduce the wear of the machine and ensure that the machine has a longer service life.

[0045] refer to Figure 4As shown, as a preferred embodiment of the present application, the length of the middle arc-shaped scale-like pressing plate 40 of the present application is greater than the lengths of the corresponding several arc-shaped scale-like pressing plates 40 on both sides. Correspondingly, the length of the middle airbag 51 is greater than the lengths of the several airbags 51 on both sides, and the number of springs 52 connected to the middle airbag 51 is also greater than the number of springs 52 connected to the airbags 51 on both sides. The purpose of doing this is to reduce the number of airbags 51 to be set, avoid the operator repeatedly inflating multiple airbags 51, and reduce the labor intensity of the operator.

[0046] Also refer to Figure 4 As shown, the present application provides rounded corner structures 41 on both sides of the arc-shaped scale-type pressing sheet 40 in the width direction, which can ensure that the bottom paper and the corrugated paper will not be scratched during the movement, thereby playing a role in protecting the bottom paper and the corrugated paper.
