Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper box production, and in particular to a production process of a corrugated paper box capable of resisting deformation. Background Art

[0002] Corrugated paper is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated board and double corrugated board. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, convenient storage and transportation, etc. More than 80% of corrugated paper can be recycled, and corrugated paper can be folded into corrugated boxes. Corrugated boxes are an ideal packaging container. It is light, firm, vibration-absorbing and suitable for mechanized production. Over the years, it has won the market with its exquisite appearance and excellent internal quality. In addition to protecting the goods and facilitating warehousing and transportation, it also plays a role in beautifying and promoting the goods.

[0003] With the continuous growth of market demand, the scale of corrugated box production has expanded rapidly, and market competition has become increasingly fierce. This requires a comprehensive study of the production process of corrugated boxes. Since corrugated boxes are made of corrugated paper, which is easily affected by moisture, once the corrugated box becomes damp, it will affect the structural strength of the corrugated box, which will eventually affect not only its normal use, but also the storage of items inside the corrugated box. To solve the above problems, a solution is proposed below. Summary of the invention

[0004] The purpose of the present invention is to provide a process for producing a corrugated paper box that is resistant to deformation, so as to solve the problems raised in the above-mentioned background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A process for producing a deformation-resistant corrugated paper box comprises the following steps: S1, paper separation: a paper separation and creasing machine can be used to creasing the formed corrugated paperboard and complete the trimming to ensure the paperboard size and crease accuracy;

[0007] S2. Printing: The corrugated cardboard can be printed by a printing press;

[0008] S3. Cartoning: Automatic carton nailing machine can accurately drive steel nails into the joints of folded corrugated cardboard to achieve a firm seal of the carton;

[0009] S4. Spraying waterproof coating: Use the spray gun of the sprayer to evenly spray the waterproof coating around the outer wall of the corrugated box;

[0010] S5. Drying: The waterproof coating on the outer wall of the corrugated cardboard box can be dried by a dryer to improve the adhesion of the waterproof coating.

[0011] S6. Strapping and Inspection: The finished cardboard boxes can be packed by an automatic strapping machine and undergo subsequent compressive strength tests, edge crush strength tests, and moisture resistance tests to ensure that their load-bearing capacity, anti-deformation ability, and moisture resistance meet the standards.

[0012] Preferably, in S1, the scoring wheel can apply pressure to the corrugated cardboard to form regular and clear folding lines. At the same time, the paper-cutting and scoring machine can also perform edge-cutting and grooving operations.

[0013] Preferably, in S2, flexographic printing is adopted. The printing plate is made of rubber, with the graphic part on its surface protruding and the non-graphic part sunken. The anilox roller dips the ink from the ink trough. After the doctor blade scrapes off the excess ink, a certain amount of ink remains in the cells, facilitating the anilox roller to evenly transfer the ink to the protruding graphic part of the printing plate. The printing plate contacts the impression cylinder, and the ink on the graphic part is transferred to the corrugated cardboard by slight pressure.

[0014] Preferably, in S3, when the pre-cut corrugated cardboard is fed into the automatic box nailing machine, through its positioning mechanism, the cardboard can be ensured to be folded in the correct position. Immediately afterwards, steel nails are accurately driven into the preset positions by a high-speed operating nail gun, thus realizing the sealing of the cardboard box.

[0015] Preferably, in S4, the spraying machine can pressurize the inhaled waterproof coating and transport it to the spray gun through a high-pressure hose. The waterproof coating is a water-soluble waterproof coating. The spray gun can spray the atomized waterproof coating on the outer wall of the corrugated cardboard box until a smooth coating layer is formed.

[0016] Preferably, in S5, the dryer is internally provided with a hot air circulation system, including a centrifugal fan and frequency conversion control. Through forced convection heat transfer, the hot air can dry the outer wall of the corrugated cardboard box, effectively removing the moisture in the waterproof coating.

[0017] Preferably, in S6, the automatic strapping machine can detect information such as the position, size, and shape of the corrugated cardboard box through sensors. According to the size and shape of the corrugated cardboard box, the automatic strapping machine can adjust the length and width of the strapping material through a mechanical structure. In the strapping area, the automatic strapping machine winds the strapping material around the item and completes the binding through a mechanical structure and a reel. Once the strapping is completed, the automatic strapping machine uses a cutting tool to cut off the strapping material. The cutting tool is usually a blade or a hot cutting mechanism.

[0018] Preferably, in S6, a carton compression tester can be used to detect the compression resistance of the corrugated carton, so as to detect whether its compression strength meets the standard; a edge crush tester can be used to detect the edge crush strength of the corrugated carton, so as to calculate whether the edge crush strength of the material meets the standard; the corrugated carton is placed in a relative humidity environment for 48 hours, so as to test the moisture difference before and after, and evaluate whether its moisture-proof performance meets the standard through the change of the water absorption rate of the corrugated carton.

[0019] The beneficial effects of the present invention are as follows: it has a more perfect and reasonable technological process. The corrugated cartons produced through the above technological process have the advantages of high strength, good anti-deformation and moisture-proof effects. Among them, the compression resistance, edge crush strength and moisture-proof of the corrugated cartons will also be detected in the process, so as to avoid the corrugated cartons produced not meeting the required requirements, thus facilitating wide application in the technical field of corrugated carton bodies. Specific embodiments

[0020] The following are only the preferred embodiments of the present invention, and the protection scope is not limited to this embodiment. All technical solutions falling within the idea of the present invention should belong to the protection scope of the present invention.

[0021] A production process of a corrugated carton with anti-deformation function includes the following steps:

[0022] S1. Paper cutting: The corrugated cardboard can be scored by a paper cutting and scoring machine, and the edge cutting is completed to ensure the cardboard size and crease accuracy. The scoring wheel can apply pressure to the corrugated cardboard to form regular and clear folding lines, ensuring smooth subsequent folding of the cardboard. At the same time, the paper cutting and scoring machine can also perform edge cutting and grooving operations, which can not only ensure the neat edges of the cardboard, but also facilitate the subsequent formation of the corrugated carton.

[0023] S2. Printing: The corrugated cardboard can be printed by a printing machine. Flexographic printing is adopted. The printing plate is made of rubber, with the graphic part on its surface protruding and the non-graphic part sunken. The anilox roll dips the ink from the ink tank. After the doctor blade scrapes off the excess ink, a certain amount of ink is retained in the anilox cells, so that the anilox roll can evenly transfer the ink to the protruding graphic part of the printing plate. The printing plate contacts the impression cylinder, and the ink on the graphic part is transferred to the corrugated paper board through slight pressure.

[0024] S3. Assembling into a box: An automatic stapling machine can accurately drive steel nails along the joint of the folded corrugated cardboard to achieve firm sealing of the carton. When the pre-cut corrugated cardboard is fed into the automatic stapling machine, through its positioning mechanism, the cardboard can be ensured to be folded in the correct position. Then, through the high-speed operating stapler, steel nails are accurately driven into the preset position, thus realizing the sealing of the carton.

[0025] S4. Spraying waterproof coating: Using the spray gun of the spraying machine, the waterproof coating can be evenly sprayed around the outer wall of the corrugated cardboard box. The spraying machine can pressurize the inhaled waterproof coating and transport it to the spray gun through a high-pressure hose. The waterproof coating is a water-soluble waterproof coating. The spray gun can spray the atomized waterproof coating on the outer wall of the corrugated cardboard box until a smooth coating layer is formed, thereby enhancing the waterproof effect of the corrugated cardboard box.

[0026] S5. Drying: The waterproof coating on the outer wall of the corrugated cardboard box can be dried by a dryer to improve the adhesion of the waterproof coating. The dryer is internally equipped with a hot air circulation system, including a centrifugal fan and frequency conversion control. Through forced convection heat transfer, the hot air can dry the outer wall of the corrugated cardboard box, effectively removing the moisture in the waterproof coating.

[0027] S6. Strapping and inspection: The finished cardboard boxes can be packed by an automatic strapping machine. The automatic strapping machine can detect the size of the corrugated cardboard box through sensors. The sensors can be photoelectric sensors, pressure sensors or other types of sensors, which are used for information such as the position, size and shape of the corrugated cardboard box. According to the size and shape of the corrugated cardboard box, the automatic strapping machine can adjust the length and width of the strapping material through a mechanical structure. In the strapping area, the automatic strapping machine will wrap the strapping material around the item and complete the binding through a mechanical structure and a reel. Once the strapping is completed, the automatic strapping machine will use a cutting tool to cut the strapping material, and at the same time firmly fix the strapping material on the corrugated cardboard box through a mechanical structure. The cutting tool is usually a blade or a thermal cutting mechanism.

[0028] The compressive strength of the corrugated cardboard box can be detected by a cardboard compression tester. The corrugated cardboard box is pressurized with a uniformly increasing displacement, and the maximum force value it can withstand is recorded, so as to detect whether its compressive strength meets the standard; the edge crush strength of the corrugated cardboard box can be detected by an edge crush strength measuring instrument. A longitudinal pressure can be applied to the corrugated cardboard box, and at the same time the deformation situation under the action of the pressure is measured, so as to calculate whether the edge crush strength of the material meets the standard; the corrugated cardboard box is placed in an environment of 50°C and 90% relative humidity for 48 hours, and then the moisture difference before and after is tested. The moisture-proof performance of the corrugated cardboard box is evaluated by the change in the water absorption rate of the corrugated cardboard box.

[0029] The present invention has a more perfect and reasonable technological process. The corrugated cardboard boxes produced through the above technological process have the advantages of high strength, good anti-deformation and moisture-proof effects. During the process, the compressive strength, edge crush strength and moisture-proof performance of the corrugated cardboard box will also be detected, avoiding the situation that the produced corrugated cardboard boxes do not meet the required standards, thus facilitating wide application in the technical field of corrugated cardboard boxes.

[0030] The specific embodiments described above further elaborate on the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention. It should be understood that the above description is only for the specific embodiments of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
