Description

Technical Field

[0001] This utility model relates to the field of linerboard processing technology, and in particular to a moisture-proof and mildew-proof treatment device for linerboard. Background Technology

[0002] In the modern packaging industry, linerboard, with its excellent toughness, strength, and processing adaptability, has become the main material for packaging various commodities. From food and electronics to furniture and building materials, linerboard boxes play an important role in product transportation, storage, and protection. However, linerboard is mainly composed of plant fibers, and this natural material easily absorbs moisture in humid environments, leading to problems such as decreased strength and deformation. It also provides a breeding ground for mold, causing mildew and rot, which seriously affects the performance of the linerboard and the safety of the packaged goods.

[0003] In existing technologies, when applying moisture-proof and mildew-proof coatings to linerboard, the coating is sprayed onto the surface of the linerboard using an internal spraying device. This process is then completed with the assistance of an ultraviolet sterilization device. However, traditional treatment devices cannot pre-treat the dust and moisture on the surface of the linerboard, making it difficult for the moisture-proof coating to adhere firmly to the surface during subsequent moisture-proof and mildew-proof treatment. This severely affects the moisture-proof and mildew-proof effect of the linerboard. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the above-mentioned equipment cannot remove dust and moisture from the surface of the linerboard, resulting in low adhesion of the moisture-proof coating during the processing of the linerboard. Therefore, this invention proposes a moisture-proof and mildew-proof treatment device for linerboard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a moisture-proof and mildew-proof treatment device for corrugated paperboard, comprising a pretreatment mechanism, wherein a main body mechanism is provided on the top of the pretreatment mechanism;

[0006] The pretreatment mechanism includes a workbench, a mounting frame is fixedly installed on the top of the workbench, the top of the mounting frame has multiple insertion slots, nozzles are fixedly inserted into the inner surface of the multiple insertion slots, and connecting pipes are fixedly connected between the outer surface walls of the multiple nozzles. An air pump is fixedly installed on the top of the mounting frame, and the outer surface wall of the air pump is fixedly connected to the outer surface wall of the connecting pipe.

[0007] Preferably, a support frame is fixedly installed on the top of the workbench, and the top of the support frame has multiple air inlet slots.

[0008] Preferably, a power supply is fixedly installed on the top of the support frame, and two filter plates are fixedly installed on the inner wall of the support frame.

[0009] Preferably, a heating tube is provided between the outer walls of the two filter plates, and the outer wall of the heating tube is fixedly connected to the outer wall of the power source.

[0010] Preferably, a fixing plate is fixedly installed on the inner wall of the support frame, two fans are fixedly installed on one side of the outer wall of the fixing plate, two sets of support plates are fixedly installed on the top of the workbench, and two limiting rollers are movably inserted between the inner walls of the two sets of support plates.

[0011] Preferably, the main body includes a mounting box, and a motor is fixedly mounted on one side of the outer wall of the mounting box.

[0012] Preferably, the output end of the motor is fixedly fitted with a first gear, and two coating rollers are movably inserted between the inner walls of the mounting box, with a second gear fixedly fitted on the outer walls of both coating rollers.

[0013] Preferably, the outer walls of the two second gears mesh with each other, one of the outer walls of the second gear meshes with the outer wall of the first gear, and a mounting plate is fixedly installed between the inner walls of the mounting box.

[0014] Preferably, a delivery pipe is fixedly inserted into the inner wall of the mounting plate, a fixing frame is fixedly installed on the inner wall of the mounting box, multiple ultraviolet lamps are fixedly installed between the inner walls of the fixing frame, and a scraper is fixedly installed on the inner wall of the mounting box.

[0015] Preferably, the top of the workbench is fixedly connected to the bottom of the mounting box.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In use, when it is necessary to treat the dust and moisture on the surface of the linerboard, the linerboard moves between the limiting rollers under the action of the external winding device. When the linerboard moves into the mounting frame, the dust on the surface of the linerboard can be blown away by the air pump, connecting pipe and nozzle, so as to avoid the dust adhering to the surface of the linerboard affecting subsequent processing. Subsequently, when the linerboard continues to move into the support frame, the external air can be delivered to the surface of the linerboard by the action of the fan and air inlet. When the air enters the support frame, it can be heated by the power supply and heating pipe. The delivered hot air can dry the moisture on the surface of the linerboard, thereby effectively treating the dust and moisture on the surface of the linerboard, and making the subsequent moisture-proof and mildew-proof treatment of the linerboard more effective.

[0018] In use, after the pre-treated linerboard enters the mounting box, the motor, first gear, and second gear drive two coating rollers to rotate in opposite directions. Water-based polyurethane is coated onto the linerboard surface through the conveying pipe, and excess polyurethane is removed by a scraper. After drying, a dense hydrophobic film is formed, improving the moisture-proof effect of the linerboard. Furthermore, under ultraviolet light, mold on the linerboard surface is effectively killed, preventing mold erosion. This completes the moisture-proof and mold-proof treatment of the linerboard, greatly improving the practicality of the equipment. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figures 1-5 As shown, this utility model provides a moisture-proof and mildew-proof treatment device for boxboard paper, including a pretreatment mechanism 1, and a main body mechanism 2 is provided on the top of the pretreatment mechanism 1;

[0029] The pretreatment unit 1 includes a workbench 11, a mounting frame 12 fixedly mounted on the top of the workbench 11, a plurality of insertion slots 121 formed on the top of the mounting frame 12, nozzles 122 fixedly inserted into the inner walls of the plurality of insertion slots 121, and connecting pipes 123 fixedly connected between the outer walls of the plurality of nozzles 122, an air pump 124 fixedly mounted on the top of the mounting frame 12, the outer wall of the air pump 124 being fixedly connected to the outer wall of the connecting pipes 123, and a support frame 13 fixedly mounted on the top of the workbench 11, the top of the support frame 13 having a plurality of air inlet slots 13. 1. A power supply 132 is fixedly installed on the top of the support frame 13. Two filter plates 133 are fixedly installed on the inner wall of the support frame 13. A heating pipe 134 is arranged between the outer walls of the two filter plates 133. The outer wall of the heating pipe 134 is fixedly connected to the outer wall of the power supply 132. A fixing plate 135 is fixedly installed on the inner wall of the support frame 13. Two fans 136 are fixedly installed on one side of the outer wall of the fixing plate 135. Two sets of support plates 111 are fixedly installed on the top of the workbench 11. Two limiting rollers 112 are movably inserted between the inner walls of the two sets of support plates 111.

[0030] The overall effect of Embodiment 1 is that when it is necessary to clean the dust and moisture on the surface of the linerboard, firstly, under the operation of the operator, one end of the linerboard is passed through the equipment and fixed to the surface of the external winding device. The winding device then winds up the linerboard, causing it to move between the limit rollers 112. When the linerboard moves into the mounting frame 12, external air is pressurized and delivered to the nozzle 122 by the air pump 124 connected to the pipe 123. The high-pressure air is then sprayed out from the nozzle 122, acting on the surface of the linerboard to clean the dust and prevent the dust from affecting subsequent packaging. The paperboard processing is affected, and then the linerboard continues to move into the support frame 13. Under the action of the fan 136 inside the support frame 13, external air can enter the support frame 13 through the air inlet slot 131. At the same time, under the action of the power supply 132 and the heating tube 134, the air entering the support frame 13 can be heated. And under the action of the filter plate 133, the dust in the air can be adsorbed and filtered, so that the high temperature air reaches the surface of the linerboard, thereby drying the moisture on the surface of the linerboard and avoiding the moisture from affecting the subsequent processing of the linerboard, greatly improving the moisture-proof and mildew-proof treatment of the subsequent linerboard.

[0031] Example 2: Figures 2-5 As shown, the main body 2 includes a mounting box 21. A motor 211 is fixedly mounted on one side of the outer wall of the mounting box 21. A first gear 212 is fixedly sleeved on the output end of the motor 211. Two coating rollers 22 are movably inserted between the inner walls of the mounting box 21. A second gear 221 is fixedly sleeved on the outer walls of both coating rollers 22. The outer walls of the two second gears 221 mesh with each other. The outer wall of one of the second gears 221 meshes with the outer wall of the first gear 212. A mounting plate 23 is fixedly mounted between the inner walls of the mounting box 21. A conveying pipe 231 is fixedly inserted into the inner wall of the mounting plate 23. A fixing frame 24 is fixedly mounted on the inner wall of the mounting box 21. Multiple ultraviolet lamps 241 are fixedly mounted between the inner walls of the fixing frame 24. A scraper 25 is fixedly mounted on the inner wall of the mounting box 21. The top of the workbench 11 is fixedly connected to the bottom of the mounting box 21.

[0032] The overall effect of Embodiment 2 is that after the linerboard has completed pretreatment, it continues to move under the action of the external winding device. When it reaches the inside of the mounting box 21, the motor 211 drives the first gear 212 to rotate, and the second gear 221 drives the two coating rollers 22 to rotate in opposite directions. At the same time, the conveying pipe 231 is connected to the external water-based polyurethane storage tank, and the water-based polyurethane is conveyed and sprayed out from the conveying pipe 231 under the action of the external conveying pump. Under the action of the coating rollers 22, the water-based polyurethane can be coated. Polyurethane is uniformly coated on the surface of the linerboard. Then, through the continuous movement of the linerboard, the excess water-based polyurethane on the surface of the linerboard can be removed by the scraper 25. After subsequent drying treatment, the water-based polyurethane can form a hydrophobic film on the surface of the linerboard, preventing the linerboard from being affected by moisture during subsequent use. While the linerboard is in continuous movement, the mold on the surface of the linerboard can be eliminated by the ultraviolet lamp 241, preventing the linerboard from rotting due to mold in subsequent use, thereby extending the service life of the linerboard.

[0033] Working principle: When moisture-proof and mildew-proof treatment is required for linerboard, the operator first passes one end of the linerboard through the equipment and fixes it to the surface of the external winding device. The winding device then winds the linerboard, causing it to move between the limit rollers 112. When the linerboard moves into the mounting frame 12, external air is pressurized and delivered to the nozzle 122 by the air pump 124 and connecting pipe 123. The high-pressure air is then sprayed out from the nozzle 122, acting on the surface of the linerboard to remove dust. Cleaning is performed to prevent dust from affecting subsequent linerboard processing. The linerboard then continues to move into the support frame 13. Under the action of the fan 136 inside the support frame 13, outside air enters the support frame 13 through the air inlet 131. Simultaneously, the air entering the support frame 13 is heated by the power supply 132 and the heating element 134. Furthermore, the filter plate 133 adsorbs and filters dust from the air, allowing the high-temperature air to reach the surface of the linerboard, thereby removing moisture from the surface of the linerboard. After the drying process and pretreatment of the linerboard, the linerboard continues to move under the action of the external winding device. When it reaches the inside of the mounting box 21, the motor 211 drives the first gear 212 to rotate, and the second gear 221 drives the two coating rollers 22 to rotate in opposite directions. At the same time, the conveying pipe 231 is connected to the external water-based polyurethane storage tank, and the water-based polyurethane is conveyed and sprayed out from the conveying pipe 231 under the action of the external conveying pump. Under the action of the coating rollers 22, the water-based polyurethane is evenly coated. The water-based polyurethane is evenly coated on the surface of the linerboard. Then, through the continuous movement of the linerboard, the excess water-based polyurethane on the surface of the linerboard can be removed by the scraper 25. After subsequent drying treatment, the water-based polyurethane can form a hydrophobic film on the surface of the linerboard, preventing the linerboard from being affected by moisture during subsequent use. While the linerboard is in continuous movement, the mold on the surface of the linerboard can be eliminated by the ultraviolet lamp 241, preventing the linerboard from rotting due to mold in subsequent use and extending the service life of the linerboard.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
