Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of carton detection, and particularly to a production and processing device and method for a high-strength moisture-proof corrugated carton. Background Art
[0002] In the modern packaging industry, corrugated cartons, as a widely used packaging material, are of crucial quality. Especially for items that need to be used or stored in a humid environment, the high strength and moisture-proof performance of corrugated cartons are directly related to the safety and quality of the packaged items.
[0003] In the traditional production and processing of corrugated cartons, there are many deficiencies in the detection methods for the strength and moisture-proof performance of cartons. Regarding the detection of moisture-proof performance, the existing technology cannot efficiently simulate the water vapor penetration process in a real humid environment. Previous detection methods may simply place the carton in an environment with a certain humidity, where the water vapor penetration speed is slow and uneven, making it difficult to comprehensively and quickly detect the performance changes of the carton in a humid environment. Moreover, by spraying water for humidification, the carton will be soaked through, which will interfere with the detection results and lead to misjudgment of the carton's moisture-proof performance.
[0004] Therefore, the present invention provides a production and processing device and method for a high-strength moisture-proof corrugated carton. Summary of the Invention
[0005] In view of the above deficiencies in the existing technology, the present invention provides a production and processing device and method for a high-strength moisture-proof corrugated carton, which accelerates the water vapor penetration speed and quickly simulates the state of the carton after getting wet.
[0006] The present invention provides the following technical solutions: A production and processing device for a high-strength moisture-proof corrugated carton includes a base and two hydraulic lifting arms installed on the base. The tops of the two hydraulic lifting arms are connected by a support rod. A sealed box is installed on the base, and a pressure arm is provided between the two hydraulic lifting arms. The hydraulic lifting arms control the up and down movement of the pressure arm. The bottom end of the pressure arm is connected to a pressing plate through a pressure sensor, and the hydraulic lifting arms control the pressure arm to drive the pressing plate to move downwards so that the pressing plate seals the top of the sealed box.
[0007] A humidifier is provided inside the base, and the humidifier is communicated with the sealed box through a pipeline to introduce water vapor. An adjusting device for air pressure regulation is provided inside the base. The adjusting device repeatedly pressurizes and depressurizes the air pressure inside the sealed box and controls the air flow so that the water vapor quickly penetrates into the corrugated carton under intermittent pressure pulses.
[0008] Inside the sealed box, there is a liftable platform. When the platform moves to the top of the sealed box, the corrugated cardboard box on the platform is pressed down by a pressing plate to detect its strength. When the platform moves to the bottom of the sealed box, the pressing plate docks with the sealed box to form a sealed space. The air pressure is adjusted by an adjusting device to make the corrugated cardboard box get wet quickly, and then the corrugated cardboard box is pushed out by the platform. Then, the cardboard box is pressed down by the pressing plate to detect the strength of the corrugated cardboard box in the wet state and test the moisture-proof performance of the corrugated cardboard box.
[0009] At the bottom end of the platform, there is a guiding structure for condensing water diversion. The condensing water is drained through the guiding structure and drips from the periphery of the corrugated cardboard box. The platform contacts the cardboard box and reduces the contact between the condensing water and the cardboard box.
[0010] Preferably, four groups of pressure sensors are symmetrically arranged at the bottom end of the pressure arm, and the pressure arm is connected to the four corners of the pressing plate through the four groups of pressure sensors.
[0011] Preferably, the adjusting device includes an air pump installed inside the base. The two ends of the air pump are respectively connected with an A air pipe and a B air pipe. The other ends of the A air pipe and the B air pipe are respectively installed with an A three-way valve and a B three-way valve. One ends of the A three-way valve and the B three-way valve are respectively connected to the sealed box through a C air pipe and a D air pipe, and the C air pipe and the D air pipe are respectively located at both ends of the sealed box.
[0012] Preferably, when the adjusting device pressurizes the sealed box, the air pump runs, and the A three-way valve and the B three-way valve are adjusted so that the outside air passes through the B three-way valve, the B air pipe, the A air pipe and the C air pipe, and finally is introduced into the sealed box. Through the high-pressure environment, the speed of water vapor penetrating the corrugated cardboard box is accelerated.
[0013] Preferably, after the sealed box is pressurized, the internal air flow of the sealed box is adjusted by the adjusting device. The air pump runs, and the A three-way valve and the B three-way valve are adjusted so that the internal air of the sealed box is introduced into the sealed box again through the D air pipe, the B air pipe, the A air pipe and the C air pipe, so that the internal air of the sealed box flows and the water vapor distribution is accelerated.
[0014] Preferably, after the internal air of the sealed box flows, pressure relief is required through the adjusting device. The A three-way valve and the B three-way valve are adjusted so that the internal air of the sealed box passes through the D air pipe, the B air pipe and the A air pipe, and finally is discharged through the A three-way valve. Through multiple pressurizations and pressure reliefs, an intermittent pressure pulse is formed to further accelerate the water vapor penetration.
[0015] Preferably, the guiding structure includes a rectangular groove formed at the bottom of the pressing plate. Inside the rectangular groove, there are two symmetrically distributed diversion plates, and the diversion plates are hinged inside the rectangular groove. The two diversion plates and the rectangular groove are connected by silk ribbons. The two diversion plates rotate and move downward under gravity and form a V shape under the connection of the silk ribbons, so that the condensed water on them is discharged through the inclined surface of the diversion plates. At the bottom end of the pressing plate, there are two groups of symmetrically distributed A electromagnets and B electromagnets. The diversion plates are adsorbed and rotated upward by the A electromagnets, and the diversion plates are adsorbed and fixed by the A electromagnets and B electromagnets.
[0016] Preferably, the platform includes a diversion groove installed at the bottom end inside the sealed box, and the bottom end of the diversion groove extends into the base through a pipeline and is connected to the water tank of the humidifier, so that the condensed water can be reused. At the four corners of the top of the diversion groove, there are support plates installed through support feet. On the support plates, there are several groups of array - distributed thimble pins. At the four corners of the bottom of the diversion groove, there are electric cylinders, and the moving ends of the electric cylinders are connected to the table board through the support plates. There are several groups of array - distributed rectangular drainage holes opened on the table board. When the table board contacts the support plate, the thimble pins pass through the rectangular drainage holes and support the corrugated cardboard box.
[0017] Preferably, there are several groups of holes for discharging condensed water opened on the support plate, so that the condensed water on the support plate drips into the diversion groove.
[0018] A production and processing method for a high - strength anti - moisture - returning corrugated cardboard box is as follows:
[0019] S1. First, the platform moves to the top of the sealed box, and the corrugated cardboard box is placed on it. The hydraulic lifting arm controls the pressure arm to drive the pressing plate downward, so as to squeeze the corrugated cardboard box and detect its strength.
[0020] S2. After detection, replace the corrugated cardboard box. The platform drives the corrugated cardboard box into the sealed box. At this time, the hydraulic lifting arm controls the pressure arm to drive the pressing plate downward, so that the pressing plate seals the sealed box, and the guiding structure opens. The humidifier introduces a large amount of water vapor into the sealed box, and the air pressure is adjusted through the adjusting device, so that the water vapor quickly penetrates into the corrugated cardboard box under intermittent pressure pulses.
[0021] S3. Then the hydraulic lifting arm drives the pressing plate upward, the guiding structure resets, and the corrugated cardboard box is ejected by the platform. Then, the cardboard box is pressed by the pressing plate to detect the strength of the corrugated cardboard box in the humid state and detect the moisture - proof performance of the corrugated cardboard box.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] (1) Water vapor is introduced into the sealed box through a humidifier, and the regulating device performs operations such as pressurization, air flow regulation, and pressure relief to form intermittent pressure pulses, which accelerate the speed of water vapor penetrating the corrugated cardboard box, enabling the water vapor to enter the interior of the corrugated cardboard box more quickly and fully, effectively simulating a humid environment and facilitating the detection of the moisture-proof performance of the corrugated cardboard box.
[0024] (2) In the guiding structure, the two flow guiding plates rotate and move downward under gravity to form a V shape, which can cause the condensed water generated in the sealed box to flow out along the inclined surface of the flow guiding plate and drip from the periphery of the corrugated cardboard box, reducing the contact area between the condensed water and the cardboard box and preventing the condensed water from dripping onto the corrugated cardboard box and affecting the test results. The flow guiding groove on the platform can collect the condensed water on the support plate and return it to the water tank of the humidifier through a pipeline, realizing the recycling of condensed water, saving water resources, and reducing the operating cost of the equipment.
[0025] (3) By performing pressurization, air flow regulation, and pressure relief operations multiple times to form intermittent pressure pulses, the speed of water vapor penetrating the corrugated cardboard box is accelerated. At the same time, the entire test process is orderly and highly automated, improving the test efficiency. Description of the Drawings

Specific implementation manners
[0038] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known components are omitted in the present disclosure to avoid unnecessarily confusing the concepts of the present invention.
[0039] Please refer to Figure 1 , a high-strength anti-moisture corrugated cardboard box production and processing device. The high-strength anti-moisture corrugated cardboard box production and processing device of the present invention mainly consists of components such as a base 1, a hydraulic lifting arm 2, a sealed box 3, a pressure arm 4, a pressing plate 5, a platform 6, a humidifier 7, an adjustment device 8, and a guiding structure 9.
[0040] The base 1 serves as the basic support structure of the entire device. Two hydraulic lifting arms 2 are precisely installed on the base 1, and the tops of the hydraulic lifting arms 2 are connected by high-strength support rods to enhance the structural stability and load-bearing capacity. The hydraulic lifting arm 2 adopts an advanced hydraulic drive system, which can realize the smooth and precise up-and-down movement of the pressure arm 4.
[0041] The sealed box 3 is tightly installed on the base 1 to provide a relatively enclosed space for the testing of corrugated cardboard boxes. The pressure arm 4 is arranged between the two hydraulic lifting arms 2, and its bottom end is connected to the pressing plate 5 through a high-precision pressure sensor. The pressure sensor is strictly calibrated and can accurately measure the pressure exerted by the pressing plate 5 on the corrugated cardboard box, providing reliable data for subsequent strength detection.
[0042] Four groups of high-precision pressure sensors are symmetrically arranged at the bottom end of the pressure arm 4, and the pressure arm 4 is connected to the four corners of the pressing plate 5 through these four groups of pressure sensors. When it is necessary to detect the strength of the corrugated cardboard box, the hydraulic lifting arm 2 controls the pressure arm 4 to drive the pressing plate 5 to move downward, and the pressing plate 5 squeezes the corrugated cardboard box placed on the platform 6. At this time, the four groups of pressure sensors monitor the pressure exerted by the pressing plate 5 on the corrugated cardboard box in real time, and transmit the pressure data to the control system of the equipment. Through the calculation and analysis of the control system, the strength value of the corrugated cardboard box is obtained.
[0043] During the equipment installation process, strictly control the installation accuracy of each component. For the hydraulic lifting arm 2, ensure that it is vertically installed and moves smoothly, avoiding jamming or shaking. The installation position of the pressure sensor should be accurate, ensuring a tight and reliable connection between it and the pressure arm 4 and the pressing plate 5. The humidifier 7 and the regulating device 8 are installed inside the base 1 and are connected to the sealed box 3 through pipes with good sealing performance to prevent water vapor and gas from leaking during transmission. The platform 6 is installed inside the sealed box 3, and the guiding structure 9 is installed at the bottom of the pressing plate 5. Water vapor is introduced into the sealed box 3 through the humidifier 7 to maintain the water vapor content inside the sealed box 3.
[0044] Refer to Figure 8 , the regulating device 8 includes an air pump 81 installed inside the base 1. The two end interfaces of the air pump 81 are respectively connected to an A air pipe 82 and a B air pipe 83. The other ends of the A air pipe 82 and the B air pipe 83 are respectively installed with an A three-way valve 84 and a B three-way valve 85. One ends of the A three-way valve 84 and the B three-way valve 85 are respectively connected to the sealed box 3 through a C air pipe 86 and a D air pipe 87, and the C air pipe 86 and the D air pipe 87 are respectively located at both ends of the sealed box 3.
[0045] Refer to Figure 9 , pressurization process: When the regulating device 8 pressurizes the sealed box 3, the air pump 81 operates, and the A three-way valve 84 and the B three-way valve 85 are adjusted so that the outside air passes through the B three-way valve 85, the B air pipe 83, the A air pipe 82, and the C air pipe 86, and finally is introduced into the sealed box 3. In a high-pressure environment, the speed of water vapor penetrating the corrugated cardboard box is accelerated, enabling the water vapor to enter the inside of the corrugated cardboard box more quickly.
[0046] Refer to Figure 10 , air flow regulation process: After the sealed box 3 is pressurized, the internal air flow of the sealed box 3 is regulated through the regulating device 8. The air pump 81 operates, and the A three-way valve 84 and the B three-way valve 85 are adjusted again so that the air inside the sealed box 3 passes through the D air pipe 87, the B air pipe 83, the A air pipe 82, and the C air pipe 86 and is introduced into the sealed box 3 again. Such an operation makes the air inside the sealed box 3 form a circulating flow, accelerating the distribution of water vapor in the sealed box 3 and ensuring that all parts of the corrugated cardboard box can fully contact the water vapor.
[0047] Refer to Figure 11, Pressure relief process: After the air inside the sealed box 3 flows, it is necessary to release the pressure through the regulating device 8, and adjust the A three-way valve 84 and the B three-way valve 85 to make the air inside the sealed box 3 pass through the D air pipe 87, the B air pipe 83 and the A air pipe 82, and finally be discharged through the A three-way valve 84. By repeatedly performing pressurization and pressure relief operations, intermittent pressure pulses are formed, which further accelerates the speed of water vapor penetrating the corrugated box and improves the test efficiency.
[0048] After the pressurization process is completed, the sealed box 3 needs to enter an air flow environment. This step is maintained for 10-20 minutes. The air flow strengthens the internal water vapor flow and makes the water vapor evenly distributed. Finally, the pressure is released to restore the sealed box 3 to normal pressure. After that, the above steps are repeated again. After multiple cycles, the water vapor penetration is strengthened through intermittent pressure changes. In the pressurization process, water vapor is introduced into the sealed box 3 through the humidifier 7 to maintain the internal water vapor content of the sealed box 3.
[0049] See also Figure 2 and Figure 3 as well as Figure 4 The guide structure 9 includes a rectangular groove 91 opened at the bottom of the pressing plate 5, and two symmetrically distributed guide plates 92 are arranged inside the rectangular groove 91, and the guide plates 92 are hinged inside the rectangular groove 91. The two guide plates 92 and the rectangular groove 91 are connected by a ribbon 95. The two guide plates 92 rotate downward under gravity and form a V shape under the connection of the ribbon 95, so that the condensed water on the guide plates is discharged through the inclined surface of the guide plates 92 to prevent the condensed water from dripping onto the corrugated box. The bottom end of the pressing plate 5 is provided with two groups of symmetrically distributed A electromagnets 93 and B electromagnets 94.
[0050] When the corrugated paper box needs to be tested for humidity, the guide structure 9 is opened, that is, the A electromagnet 93 and the B electromagnet 94 are powered off, and the two guide plates 92 rotate downward under the action of gravity to form a V shape. At this time, the condensed water generated in the sealing box 3 will be discharged along the inclined surface of the guide plate 92 and drip from the periphery of the corrugated paper box, reducing the contact area between the condensed water and the paper box. When the humidity test is completed, the hydraulic lifting arm 2 drives the pressing plate 5 to move upward. At this time, the A electromagnet 93 and the B electromagnet 94 are powered on, and the guide plate 92 is adsorbed and rotated upward, so that the guide plate 92 is fixed, and the guide structure 9 is reset, which is convenient for pressing down to perform strength testing.
[0051] See also Figure 5 and Figure 6, the platform 6 includes a diversion groove 61 installed at the inner bottom end of the sealed box 3, and the bottom end of the diversion groove 61 extends to the inside of the base 1 through a pipeline and is connected to the water tank of the humidifier 7, enabling the reuse of condensed water. At the four corners of the top of the diversion groove 61, support plates 62 are installed through support feet, and several groups of array-distributed thimbles 63 are installed on the support plates 62. At the four corners of the bottom of the diversion groove 61, electric cylinders 64 are installed, and the moving ends of the electric cylinders 64 are connected to the platen 65 through the support plates 62. A plurality of groups of rectangular drainage holes 66 distributed in an array are opened on the platen 65. The rectangular drainage holes 66, as Figure 7 shown, a plurality of groups of holes for discharging condensed water are opened on the support plate 62.
[0052] When the platform 6 moves to the top of the sealed box 3, the corrugated cardboard box is placed on the support plate 62, and at this time, the thimbles 63 support the corrugated cardboard box. When it is necessary to conduct a moisture test on the corrugated cardboard box, the electric cylinder 64 drives the platen 65 to move downward, so that the platen 65 contacts the support plate 62. After the platform 6 drives the corrugated cardboard box into the sealed box 3, the thimbles 63 pass through the rectangular drainage holes 66 for the moisture test. The corrugated cardboard box is placed on the thimbles 63, which can prevent the condensed water on the platen 65 from wetting the cardboard box.
[0053] After the test, the electric cylinder 64 drives the platen 65 to move upward, and the thimbles 63 pass through the rectangular drainage holes 66 again and support the corrugated cardboard box, pushing the corrugated cardboard box out of the sealed box 3 for subsequent strength testing. At the same time, the condensed water on the support plate 62 drips into the diversion groove 61 through the opened holes and then flows back to the water tank of the humidifier 7 through the pipeline, realizing the recycling and reuse of condensed water.
[0054] A production and processing method for a high-strength moisture-proof corrugated cardboard box is as follows:
[0055] I. Initial strength detection
[0056] First, the electric cylinder 64 drives the platform 6 to move to the top of the sealed box 3, and the corrugated cardboard box is placed on the support plate 62, and the thimbles 63 support the corrugated cardboard box. Then, the hydraulic lifting arm 2 controls the pressure arm 4 to drive the pressing plate 5 to move downward, so that the pressing plate 5 presses the corrugated cardboard box. During this process, the four pressure sensors at the bottom end of the pressure arm 4 monitor the pressure data in real time and transmit it to the control system of the device, and the initial strength value of the corrugated cardboard box is calculated through the control system.
[0057] II. Water vapor penetration and moisture test
[0058] After the detection, the corrugated cardboard box is replaced, and the electric cylinder 64 drives the platform 6 to drive the corrugated cardboard box into the sealed box 3.
[0059] At this time, the hydraulic lifting arm 2 controls the pressure arm 4 to drive the pressing plate 5 to move downward, so that the pressing plate 5 seals the sealing box 3. At the same time, the A electromagnet 93 and the B electromagnet 94 are powered off, and the guiding structure 9 is opened. The two flow guiding plates 92 rotate downward under the action of gravity and form a V shape.
[0060] The humidifier 7 introduces a large amount of water vapor into the sealing box 3, and at the same time the regulating device 8 starts to work. The air pump 81 operates. First, the A three-way valve 84 and the B three-way valve 85 are adjusted so that the outside air is introduced into the sealing box 3 through the B three-way valve 85, the B air pipe 83, the A air pipe 82 and the C air pipe 86 to pressurize the sealing box 3 and accelerate the speed of water vapor penetrating the corrugated cardboard box.
[0061] Then, the A three-way valve 84 and the B three-way valve 85 are adjusted again so that the air inside the sealing box 3 is introduced into the sealing box 3 again through the D air pipe 87, the B air pipe 83, the A air pipe 82 and the C air pipe 86, so that the air inside the sealing box 3 flows and accelerates the distribution of water vapor.
[0062] After that, the A three-way valve 84 and the B three-way valve 85 are adjusted so that the air inside the sealing box 3 passes through the D air pipe 87, the B air pipe 83 and the A air pipe 82, and finally is discharged through the A three-way valve 84 for pressure relief.
[0063] Repeat the above steps of pressurization, air flow regulation and pressure relief to form intermittent pressure pulses, so that the water vapor quickly penetrates into the corrugated cardboard box under the intermittent pressure pulses.
[0064] III. Strength detection under humid conditions
[0065] Then, the hydraulic lifting arm 2 drives the pressing plate 5 to move upward, the A electromagnet 93 and the B electromagnet 94 are powered on, the guiding structure 9 is reset, and the two flow guiding plates 92 are adsorbed and fixed.
[0066] The electric cylinder 64 drives the platform 6 to push out the corrugated cardboard box, so that the corrugated cardboard box is supported by the ejector pin 63 again.
[0067] Then, the hydraulic lifting arm 2 controls the pressure arm 4 to drive the pressing plate 5 to press the cardboard box downward. The pressure sensor at the bottom end of the pressure arm 4 monitors the pressure data in real time again. The strength value of the corrugated cardboard box under humid conditions is calculated through the control system. Through the comparison of the two data, the moisture-proof performance of the corrugated cardboard box is detected.
[0068] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims.
