Description

Technical Field

[0001] The utility model relates to the relevant field of corrugated paper production equipment, in particular to an externally applied corrugated paper laminating device and a corrugating machine. Background Art

[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] like Figure 1 As shown, in the prior art, in the manufacturing process of corrugated paper, the main corrugated roller and the auxiliary corrugated roller heat-press the base paper into corrugated paper with corrugated waves. In the production process, the main corrugated roller is heated by a boiler. When a certain temperature is reached, the suction structure 1 and the exhaust port 2 are arranged inside the main corrugated roller, that is, the main corrugated roller adopts a unified air duct and multiple air ports to provide suction for the corrugated paper, so that the corrugated paper is adsorbed on the main corrugated roller. At the same time, the glue is glued together with another flat base paper through a glue coating roller to form a corrugated board with corrugated paper on one side and flat paper on the other side.

[0004] Since the inner diameter of the main corrugated roller is relatively large, in order to ensure that the main corrugated roller has sufficient suction force on the corrugated paper, the only way to ensure sufficient suction force is to increase the induced wind power of the suction structure 1, which not only causes high noise but also wastes a lot of electricity costs; at the same time, although the gluing temperature of the corrugated paper can reach 80°C, the boiler needs to heat the main corrugated roller as a whole to 160°C to ensure that the main corrugated roller is heated evenly as a whole, which consumes a lot of energy and affects the working efficiency of the corrugated paper.

[0005] Therefore, the above-mentioned technical problems need to be further solved. Summary of the invention

[0006] The purpose of the embodiment of the utility model is to provide an externally applied corrugated paper laminating device and to alleviate the technical problems existing in the prior art in the prior art of consuming a large amount of electrical energy and heat energy during the corrugated paper production process and having low production efficiency.

[0007] In order to solve the above technical problems, the present utility model provides the following technical solutions:

[0008] The first aspect of the utility model provides an externally applied corrugated paper laminating device, comprising a main corrugated roller, a glue coating roller, an auxiliary corrugated roller, a workpiece to be processed and an anti-slipping air curtain, wherein the main corrugated roller and the auxiliary corrugated roller are used to hot-press the workpiece to be processed into corrugated paper, and transfer the corrugated paper to the glue coating roller for gluing, and the anti-slipping air curtain is arranged on the outer side of the main corrugated roller.

[0009] In some modified embodiments of the first aspect of the utility model, the anti-fall-off wind curtain includes a shell, the shell includes multiple air inlets and air outlets, the multiple air inlets are arranged on both sides of the shell, and the air outlets are arranged at the end of the shell facing the main corrugated roller.

[0010] In some modified implementations of the first aspect of the utility model, the air outlet is provided with a plurality of evenly distributed air outlet holes.

[0011] In some modified implementations of the first aspect of the utility model, the anti-fall-off air curtain also includes a heating element, which is arranged at the exhaust port in the shell, and the heating element is used to heat the gas at the exhaust port.

[0012] In some modified implementations of the first aspect of the utility model, the first support seat is provided with an upper limit plate, and further comprises a support member, a mounting plate and a moving member, and the main corrugated roller, the glue coating roller, the auxiliary corrugated roller and the anti-slip air curtain are all mounted on the support member;

[0013] One end of the mounting plate is connected to the supporting member, and the other end of the mounting plate is connected to the moving member; and the moving member is used to drive the supporting member to move through the mounting plate.

[0014] The second aspect of the utility model provides a corrugating machine, comprising the above-mentioned externally applied corrugated paper laminating device.

[0015] Compared with the prior art, the externally applied corrugated paper laminating device provided in the first aspect of the utility model sets an anti-stripping wind curtain on the outside of the main corrugated board. When gluing the corrugated paper, the anti-stripping wind curtain applies a gas blowing force to the corrugated paper on the outside of the main corrugated roller, so that the corrugated paper is adhered to the main corrugated roller under the action of the wind, so that it will not fall off even after speeding up. Since the utility model adopts the method of locally applying a gas blowing force to the main corrugated roller from the outside, compared with the prior art, which adopts a method of setting a high-power motor in the main corrugated board and using a unified air duct and multiple air ports to provide suction for the corrugated paper, the power consumption is reduced by more than 90%. At the same time, since the utility model applies a blowing force to the corrugated paper from the outside of the anti-stripping wind curtain, the temperature requirement of the corrugated paper in the gluing process can be met by directly controlling the gas temperature provided by the anti-stripping wind curtain, which reduces the setting of thermal energy parts such as boilers in the prior art, greatly reduces the consumption of thermal energy of the original product, and also reduces the preparation time for boiler heating, thereby improving the production efficiency of corrugated paper.

[0016] The corrugating machine provided in the second aspect of the utility model has similar technical effects as the external corrugated paper laminating device, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 2 As shown, the utility model provides an externally applied corrugated paper laminating device, comprising a main corrugated roller 10, a glue coating roller 30, an auxiliary corrugated roller 20, a workpiece 40 to be processed and an anti-slipping air curtain 50, wherein the main corrugated roller 10 and the auxiliary corrugated roller 20 are used to hot-press the workpiece 40 to be processed into corrugated paper, and transfer the corrugated paper to the glue coating roller 30 for gluing, wherein the anti-slipping air curtain 50 is arranged on the outside of the main corrugated roller 10, and the main corrugated roller 10 is a structure without a suction structure 1 and an exhaust port 2.

[0029] Compared with the prior art, the externally applied corrugated paper laminating device provided by the embodiment of the utility model sets the anti-slipping wind curtain 50 on the outside of the main corrugated roller 10. When gluing the corrugated paper, the anti-slipping wind curtain 50 applies a gas blowing force to the corrugated paper on the outside of the main corrugated roller 10. Under the action of the gas thrust, the corrugated paper is adhered to the main corrugated roller 10, so that it will not fall off even after speeding up, reducing power consumption by more than 90%, alleviating the technical problem of excessive power consumption in the prior art of setting a suction structure 1 inside the main corrugated roller 10 to provide suction to adsorb the corrugated paperboard to the surface of the main corrugated roller 10, thereby achieving the technical effect of reducing the energy consumption of equipment.

[0030] It should be noted that, in the present embodiment, when a single anti-slipping air curtain 50 is used, the anti-slipping air curtain 50 is arranged at the end where the gluing roller 30 is gluing the corrugated paper. Such an arrangement can ensure that the corrugated paper is tightly attached to the outer side of the main corrugated roller 10 during the gluing process, and can also facilitate heating of the corrugated paper in time after gluing so that the colloid can quickly condense on the corrugated paper. At the same time, in order to obtain a better corrugated paper laminating effect, multiple anti-slipping air curtains 50 can also be arranged in a manner of surroundingly installing along the main corrugated roller 10.

[0031] Furthermore, if Figure 3 As shown, the anti-fall-off air curtain 50 includes a shell 51 , which includes a plurality of air inlets 52 and an air outlet 53 . The plurality of air inlets 52 are arranged on both sides of the shell 51 , and the air outlet 53 is arranged at the end of the shell 51 facing the main corrugated roller 10 .

[0032] Furthermore, the air outlet 53 is provided with a plurality of evenly distributed air outlet holes.

[0033] The air inlet 52 is arranged on both sides of the shell 51 to facilitate the connection between the air inlet 52 and external equipment. At the same time, the air enters from both sides to increase the air intake in a limited space. The air outlet 53 is arranged at the end of the shell 51 facing the main corrugated roller 10, and the air outlet 53 is provided with a plurality of evenly distributed air outlet holes to ensure that the gas can be evenly blown to the corrugated paper, so that the corrugated paper is evenly stressed along the circumference of the main corrugated roller 10.

[0034] Furthermore, the anti-fall-off air curtain 50 also includes a heating element, which is disposed at the air outlet 53 in the shell 51 , and is used to heat the gas at the air outlet 53 .

[0035] The heating element can be a heating component such as a resistance wire to heat the gas at the air outlet 53, so that the corrugated paper can be heated immediately after the glue is applied, so that the colloid can be quickly condensed on the corrugated paper.

[0036] It should be noted that within this range, the colloid can be quickly bonded while avoiding damage to the corrugated paper due to excessive temperature.

[0037] Furthermore, if Figure 4 As shown, it also includes a support member 61, a mounting plate 62 and a moving member, and the main corrugating roller 10, the glue coating roller 30, and the auxiliary corrugating roller 20 are all installed on the mounting plate 62;

[0038] One end of the mounting plate 62 is connected to the support member 61 , and the other end of the mounting plate 62 is connected to the moving member; and the moving member is used to drive the support member 61 to move through the mounting plate 62 .

[0039] The support member 61 and the mounting plate 62 are arranged perpendicular to each other, wherein one end of the mounting plate 62 is connected to the support member 61, and the other end of the mounting plate 62 is connected to the moving member. Since the main corrugating roller 10, the glue coating roller 30, the auxiliary corrugating roller 20 and the anti-slip air curtain 50 are all installed on the mounting plate 62, and the anti-slip air curtain 50 is installed on the support member 61, the overall movement of the equipment can be achieved by controlling the moving member, laying the foundation for realizing the overall automation of the corrugated paper manufacturing process.

[0040] It should be noted that the staff can set the moving parts to various moving parts such as mechanical arms, cylinder assemblies, etc. according to actual conditions. At the same time, the main corrugating roller 10, the glue coating roller 30, and the auxiliary corrugating roller 20 can also be installed on the support 61 according to actual conditions.

[0041] Furthermore, if Figure 4 As shown, a support frame 110 is connected between the anti-slip air curtain 50 and the mounting plate 62 , one end of the support frame 110 facing the main corrugated roller 10 is connected to the anti-slip air curtain 50 , and the other end of the support frame 110 is slidably connected to the support member 61 .

[0042] By connecting the support frame 110 between the anti-stripping wind curtain 50 and the support member 61, the support frame 110 includes a first rod body 111 and a second rod body 112, and the second rod body 112 is hinged to the first rod body 111, so that the angle of the second rod body 112 relative to the first rod body 111 can be adjusted. At the same time, the second rod body 112 can be set in the form of a telescopic rod. When installing the anti-stripping wind curtain 50, the position of the anti-stripping wind curtain 50 can be adjusted according to the relationship between it and the gluing working area, thereby improving the accuracy of the anti-stripping wind curtain 50 in directing gas toward the corrugated paper.

[0043] Furthermore, if Figure 5 , Figure 6 and Figure 7 As shown, a drying box is also provided, and the corrugated paper is dried in the drying box after being glued.

[0044] like Figure 5 As shown, in the prior art, the drying process of the glue-coated formed corrugated paper 5 is usually carried out by heating 3 pairs of formed corrugated paper 5 arranged at the bottom of the conveyor belt 4, and the heat source is heated by boiler steam, which not only wastes a lot of coal consumption, but also causes a lot of exhaust gas pollution to the environment.

[0045] like Figure 6 and Figure 7As shown, compared with the traditional boiler steam heating, this embodiment arranges a drying box 70, and transmits the formed corrugated paper 5 through the arrangement of a support plate 72 and a conveyor belt 4. The drying box 70 is covered on the outer side of the support plate 72 and the conveyor belt 4. In order to ensure that the temperature inside the drying box 70 does not spread, the drying box 70 is provided with an entry sealing curtain 73, an exit sealing curtain 74 and an air supply port 71 along the conveying direction of the conveyor belt 4. The staff can convey hot air into the drying box 70 by setting an anti-falling wind curtain, a hot air blower, etc. Since its heat source consumes electrical energy, it not only eliminates the need for the original boiler, reduces the consumption of a large amount of coal, greatly reduces the production cost, but also reduces the exhaust gas emissions generated when the boiler provides heat energy.

[0046] In the second aspect, this embodiment further provides a corrugating machine, including the externally applied corrugated paper laminating device described above, the principle of which has been described above and will not be repeated here.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
