Description

Technical Field

[0001] This utility model relates to the field of testing technology for household paper production, and in particular to a device for testing the layering of household paper. Background Technology

[0002] Household paper products (such as facial tissues, toilet paper, and kitchen paper) mostly use a 2-4 layer structure (such as the common "3-layer thickened" facial tissues). The multi-layer design improves absorbency, toughness, and thickness (avoiding the fragility and insufficient absorbency of a single layer). However, untreated multi-layer paper has natural defects, such as a lack of bonding between layers, which makes it easy to "separate" during use (such as when wiping hands, the multiple layers fall apart, reducing actual usage efficiency).

[0003] However, in actual production, due to batch-to-batch variations in parameters such as the number of paper layers, thickness, and fiber quality, the required embossing pressure varies for different types of paper. Current production methods lack a precise inspection step for embossing pressure before embossing, relying heavily on manual experience to set fixed pressure parameters or conducting pressure tests through small-batch trial production. This approach cannot predict the risk of delamination in advance: if the pressure is too low, the multiple layers of paper will not be firmly bonded, leading to delamination in subsequent production; if the pressure is too high, the paper will easily crack, also resulting in product scrap. Once delamination defects are discovered, the invested raw materials, labor costs, and machine uptime cannot be recovered, causing serious resource waste, reducing production efficiency, and resulting in significant economic losses for the company. Summary of the Invention

[0004] Therefore, a delamination inspection device for household paper is needed to address the inability to predict the risk of delamination in existing production processes. If the pressure is too low, the multiple layers of paper will not be firmly bonded, leading to delamination in subsequent production; if the pressure is too high, the paper will easily crack, resulting in product scrap. Once a delamination defect is detected, the invested raw materials, labor costs, and machine uptime cannot be recovered, causing serious resource waste, reducing production efficiency, and resulting in significant economic losses for the enterprise.

[0005] To achieve the above objectives, the inventor provides a device for testing the delamination of household paper, comprising:

[0006] frame;

[0007] A drive mechanism, which is disposed on one side of the frame;

[0008] A drive shaft is connected to the drive mechanism and is disposed through the frame;

[0009] A creasing roller is mounted on the drive shaft, and the drive mechanism is used to drive the drive shaft to rotate, thereby driving the creasing roller to rotate.

[0010] Two cylinders are spaced apart on the frame and positioned above the pressure roller;

[0011] An air supply mechanism is provided, which is connected to the two cylinders via a pipeline and is used to provide an air source to the two cylinders.

[0012] Two embossing wheels are respectively disposed at the telescopic ends of the two cylinders. The embossing wheels are located above the embossing roller, and the cylinders are used to raise and lower the embossing wheels.

[0013] A regulating valve is provided on the pipeline between the air supply mechanism and the two cylinders, and the regulating valve is used to regulate the air supply pressure.

[0014] And a pressure gauge, which is mounted on the regulating valve.

[0015] As a preferred structure of this utility model, the frame includes a mounting bracket and a support base. The support base is fixedly disposed on one side of the mounting bracket, the drive mechanism is disposed on the support base, and the transmission shaft is transversely disposed on the support base and the mounting bracket.

[0016] As a preferred structure of this utility model, the frame further includes a mounting plate, which is fixedly disposed above the mounting support. The two cylinders are respectively disposed on the mounting plate, and the cylinders are detachably connected to the mounting plate.

[0017] As a preferred structure of this utility model, the mounting plate is provided with a plurality of mounting holes, which are evenly distributed at intervals along the mounting plate.

[0018] In a preferred embodiment of this invention, the drive mechanism is connected to the transmission shaft via a coupling.

[0019] As a preferred structure of this utility model, the transmission shaft is provided with a plurality of bearing components, which are respectively located on both sides of the pressure roller.

[0020] As a preferred structure of this utility model, the air supply mechanism is an air compressor or an air storage tank.

[0021] As a preferred structure of this utility model, the air supply mechanism includes an air compressor and an air storage tank. The air compressor and the air storage tank are connected by a pipeline, and the air storage tank is connected to the two cylinders by a pipeline.

[0022] As a preferred structure of this utility model, the outer surface of the embossing wheel is provided with raised or recessed patterns.

[0023] As a preferred structure of this utility model, the tissue paper layering inspection device further includes a control valve, which is disposed on the pipeline between the regulating valve and the two cylinders.

[0024] The advantages of the above technical solution, compared with existing technologies, are as follows: In this utility model's tissue paper delamination inspection device, during inspection, a drive mechanism drives a transmission shaft to rotate the crease roller, achieving uniform paper transport. An air supply mechanism provides a stable air source, and a regulating valve and pressure gauge precisely control the air pressure. A cylinder converts the air pressure into mechanical pressure, which is then transmitted to the embossing wheel. The embossing wheel cooperates with the crease roller, and the embossing wheel squeezes the multi-layered paper to form mechanical interlocking points, simulating the actual embossing process. The device inspects the interlayer bonding state of the embossed paper, and by appropriately adjusting the air pressure through the regulating valve, the optimal embossing pressure for the current base paper is determined, guiding subsequent production. Different embossing pressures can be simulated before embossing to inspect the interlayer bonding state of multi-layered paper, determine the optimal embossing pressure, avoid delamination risks from the source, reduce resource waste, and improve production economy.

[0062] Please see Figures 1 to 6 This embodiment relates to a tissue paper delamination inspection device. In this embodiment, the tissue paper delamination inspection device is applied to the stage of accurately inspecting the embossing pressure before embossing. It can simulate different embossing pressures before embossing to inspect the interlayer bonding state of multi-layered paper, determine the optimal embossing pressure, avoid delamination risks from the source, reduce resource waste, and improve production economy. Specifically, the tissue paper delamination inspection device includes:

[0063] Frame 1; where frame 1 is the basic support structure of the device, used to support and fix all functional components such as drive mechanism 2, transmission shaft 3, cylinder 5, etc., to ensure that each component maintains a stable relative position during operation and to provide a structural foundation for the normal operation of the device.

[0064] A drive mechanism 2 is disposed on one side of the frame 1; the drive mechanism 2 is the power source of the device, used to provide controllable rotational power to drive the transmission shaft 3 and the crease roller 4 to rotate, simulating the paper web conveying process of an embossing machine in actual production. In this embodiment, the drive mechanism 2 is a motor.

[0065] The drive shaft 3 is connected to the drive mechanism 2 and is installed through the frame 1. The drive shaft 3 is an intermediate carrier for power transmission, connecting the drive mechanism 2 and the pressure roller 4, transmitting the rotational power of the drive mechanism 2 to the pressure roller 4, and providing support for the pressure roller 4 to ensure stable rotation of the pressure roller 4.

[0066] The crease roller 4 is mounted on the drive shaft 3. The drive mechanism 2 drives the drive shaft 3 to rotate, thereby rotating the crease roller 4. The crease roller 4 acts as a "lower roller" simulating the embossing process, forming an embossing gap with the upper embossing wheel 7. It carries the multi-layered paper to be inspected and, through rotation, transports the paper along the embossing gap. Simultaneously, it provides reverse support to the embossing wheel 7, ensuring uniform pressure is applied to the paper. Furthermore, the crease roller 4 is fixedly mounted on the drive shaft 3 and rotates synchronously with it. The crease roller 4 is made of metal (such as stainless steel) with a precision-polished surface to ensure a smooth, unprotruding surface (distinct from the patterned structure of the embossing wheel 7). Its diameter and length can be designed according to the width of the paper to be inspected (e.g., for a 200mm wide tissue paper roll, the length of the crease roller 4 can be set to 250mm, reserving installation space on both sides).

[0067] Two cylinders 5 are spaced apart on the frame 1 and positioned above the embossing roller 4. Each cylinder 5 is a pressure-applying actuator, driven by the thrust of compressed gas to move its telescopic end up and down, thereby raising and lowering the embossing wheel 7 and adjusting the gap (embossing pressure) between the embossing wheel 7 and the embossing roller 4, while simultaneously providing stable pressure support for the embossing wheel 7. The piston rod extension length of each cylinder 5 adjusts the distance between the embossing wheel 7 and the embossing roller 4, thus controlling the embossing pressure applied to the multi-layered paper. After inspection, the piston rod retracts, causing the embossing wheel 7 to rise, facilitating the removal of the embossed paper and the replacement of new paper for inspection.

[0068] The air supply mechanism 6 is connected to the two cylinders 5 through pipelines. The air supply mechanism 6 is used to provide air to the two cylinders 5. The air supply mechanism 6 is the power source of the cylinders 5, which is used to provide compressed gas to provide power for the extension and retraction of the piston rod of the cylinders 5, and is the basic guarantee for pressure regulation.

[0069] Two embossing wheels 7 are respectively positioned at the telescopic ends of the two cylinders 5. The embossing wheels 7 are located above the crease roller 4, and the cylinders 5 are used to raise and lower the embossing wheels 7. The embossing wheels 7 are the "upper rollers" that simulate the embossing process. They work in conjunction with the crease roller 4 to apply pressure to the multi-layer paper and press the patterns, and are the core components for realizing "simulated embossing". Under pressure, the patterns on the surface of the embossing wheels 7 are pressed onto the multi-layer paper, forming an embossed structure consistent with actual production. The pressure applied by the cylinders 5 is evenly transmitted to local areas of the multi-layer paper (the raised areas of the patterns), simulating the "interlocking point" formation process of actual embossing.

[0070] A regulating valve 8 is installed on the pipeline between the air supply mechanism 6 and the two cylinders 5. The regulating valve 8 is used to regulate the air supply pressure; it is the core component of pressure control, used to regulate the pressure of the compressed gas output to the cylinders 5, thereby precisely controlling the pressure applied by the cylinders 5 to the embossing wheel 7, which is crucial for achieving "different pressure tests". By rotating the knob of the regulating valve 8, the opening of the valve core is changed, adjusting the pressure of the output gas, and thus controlling the thrust of the piston rod of the cylinder 5 (pressure and thrust are proportional). In conjunction with the pressure gauge 9, the current regulated pressure can be displayed in real time, facilitating the operator to record and compare test results under different pressures. The regulating valve 8 is a pressure reducing valve.

[0071] And pressure gauge 9, which is installed on the regulating valve 8. The pressure gauge 9 is directly installed on the regulating valve 8, which facilitates real-time observation of the adjusted pressure value. The pressure gauge 9 is a visual display component for pressure monitoring, used to provide real-time feedback on the gas pressure after adjustment by the regulating valve 8, providing pressure reference for operators, ensuring the accuracy of pressure adjustment and the traceability of the inspection process.

[0072] Specifically, in the tissue paper delamination inspection device of this embodiment, during inspection, the drive mechanism 2 drives the transmission shaft 3 to rotate the crease roller 4, achieving uniform paper conveying; the air supply mechanism 6 provides a stable air source, and the regulating valve 8 and pressure gauge 9 precisely control the air pressure; the cylinder 5 converts the air pressure into mechanical pressure and transmits it to the embossing wheel 7; the embossing wheel 7 cooperates with the crease roller 4, and the embossing wheel 7 squeezes the multi-layer paper to form mechanical interlocking points, simulating the actual embossing process; the interlayer bonding state of the paper after embossing is inspected, and the air pressure is appropriately adjusted by the regulating valve 8 to determine the optimal embossing pressure suitable for the current base paper, guiding subsequent production. Different embossing pressures can be simulated before embossing to inspect the interlayer bonding state of multi-layer paper, determine the optimal embossing pressure, avoid delamination risks from the source, reduce resource waste, and improve production economy.

[0073] Optionally, in some embodiments, such as Figures 1 to 6As shown, the frame 1 includes a mounting bracket 11 and a support base 12. The support base 12 is fixedly mounted on one side of the mounting bracket 11. The drive mechanism 2 is mounted on the support base 12, and the transmission shaft 3 is transversely mounted through the support base 12 and the mounting bracket 11. The mounting bracket 11 serves as the bottom foundation of the frame 1, directly contacting the ground or the workbench of the production workshop, providing stable support for the entire device and preventing displacement due to vibration during operation. The support base 12 is specifically used to mount the drive mechanism 2, ensuring a precise and stable transmission connection between the drive mechanism 2 and the transmission shaft 3 by fixing the position of the drive mechanism 2.

[0074] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the frame 1 also includes a mounting plate 13, which is fixedly disposed above the mounting support 11. Two cylinders 5 are respectively disposed on the mounting plate 13. The cylinders 5 are detachably connected to the mounting plate 13 for easy assembly.

[0075] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the mounting plate 13 is provided with a plurality of mounting holes 14, which are evenly distributed at intervals along the mounting plate 13. The mounting plate 13 is used to mount two cylinders 5. The evenly distributed mounting holes 14 can be used to adjust the mounting position of the cylinders 5 on the mounting plate 13 according to the spacing requirements of the embossing wheels 7 or the width of the paper, thereby improving the adaptability of the device to different paper sizes.

[0076] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the drive mechanism 2 and the transmission shaft 3 are connected by a coupling 31. The coupling 31 precisely transmits power to the transmission shaft 3, ensuring that the rotational speed of the transmission shaft 3 matches the output speed of the drive mechanism 2, thus avoiding slippage or speed loss during power transmission. Using the coupling 31 provides high transmission efficiency and strong stability, preventing fluctuations in the rotational speed of the embossing roller 4 due to transmission deviations, ensuring consistency between the simulated embossing process and actual production, and improving the reliability of inspection results.

[0077] Optionally, in some embodiments, such as Figures 1 to 6As shown, the drive shaft 3 is equipped with multiple bearing components 32, which are located on both sides of the pressure roller 4. The bearing components 32 are deep groove ball bearings, fixed to the support base 12 and the mounting bracket 11 by bearing seats. The bearing components 32 on both sides keep the drive shaft 3 horizontally, preventing axial displacement or radial runout of the pressure roller 4 during rotation. The bearing components 32 convert the sliding friction between the drive shaft 3 and the mounting bracket 11 into rolling friction, reducing power loss and wear on both sides, thus extending the service life of the device.

[0078] Optionally, in some embodiments, such as Figure 4 and Figure 5 As shown, the air supply mechanism 6 is an air compressor 61 or an air storage tank 62.

[0079] Optionally, in some other embodiments, such as Figure 6 As shown, the air supply mechanism 6 includes an air compressor 61 and an air tank 62. The air compressor 61 and the air tank 62 are connected by pipelines, and the air tank 62 is connected to the two cylinders 5 by pipelines. The air compressor 61 generates high-pressure gas by compressing air, and the air tank 62 is used to store the compressed gas to ensure stable air supply pressure (avoiding pressure fluctuations caused by frequent start-stop of the air compressor 61). The combined structure of "air compressor 61 + air tank 62" can achieve continuous and stable air supply, avoiding inspection errors caused by pressure fluctuations of a single air compressor 61, and is especially suitable for long-term continuous inspection scenarios.

[0080] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the outer surface of the embossing wheel 7 is provided with raised or recessed patterns. The pattern shape (such as dots, rhombuses, grids), density and depth can be designed according to the parameters of the embossing roller in actual production (to ensure that the simulation effect is consistent with the actual production). The embossing wheel 7 is made of metal material (such as alloy steel), and the surface is heat-treated (such as quenching) to improve hardness and wear resistance. It is connected to the telescopic end of the cylinder 5 through the bearing seat and can rotate freely with the paper conveying.

[0081] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the tissue paper delamination testing device also includes a control valve 10, which is installed on the pipeline between the regulating valve 8 and the two cylinders 5. The control valve 10 is a control component for the on / off of the air passage, used to control the air passage connection between the air supply mechanism 6 and the cylinders 5, enabling independent or overall control of the cylinders 5, and improving the safety and convenience of device operation.

[0082] Specifically, the working principle of the tissue paper delamination inspection device in this embodiment is a four-step coordinated process of "power-driven conveying, precise air pressure adjustment, pattern simulation interlocking, and intuitive judgment of delamination":

[0083] The drive mechanism 2 drives the creasing roller 4 to rotate via the transmission shaft 3, thereby achieving uniform paper feeding.

[0084] The air supply mechanism 6 provides a stable air source, the regulating valve 8 and the pressure gauge 9 precisely control the air pressure, and the cylinder 5 converts the air pressure into mechanical pressure and transmits it to the embossing wheel 7.

[0085] The embossing wheel 7 works in conjunction with the crease roller 4 to create mechanical interlocking points in multiple layers of paper through pattern extrusion, simulating the actual embossing process.

[0086] Inspect the interlayer bonding state of the paper after embossing, and adjust the air pressure appropriately by adjusting valve 8 to determine the optimal embossing pressure suitable for the current base paper, so as to guide subsequent production.

[0087] The tissue paper delamination testing device in this embodiment has the following beneficial effects:

[0088] 1. Break through "experience dependence" to achieve precision and data-driven stress testing.

[0089] This device utilizes a precise pressure control combination of "regulating valve 8 + pressure gauge 9," with pressure gauge 9 providing real-time pressure data feedback. Simultaneously, the structure of "crease roller 4 + pattern embossing roller 7" completely simulates the actual pressing form of an embossing roller assembly, ensuring that inspection results are highly consistent with actual production. Operators can record delamination under different pressures to establish a database corresponding to "base paper characteristics - optimal pressure" (e.g., for 3-ply, 15g / m² tissue paper, the optimal pressure is 0.4MPa), completely eliminating reliance on experience and achieving digital and precise pressure setting. This can reduce the delamination defect rate by over 80%.

[0090] 2. Avoid "trial production waste" and achieve source control of resource consumption.

[0091] This device only requires cutting a 10-20cm length of paper to be inspected to complete the pressure test (no continuous production required). The raw material loss per batch is less than 10g, far lower than the kilogram-level loss in small-batch trial production. Furthermore, the inspection process only takes 1-2 minutes, does not occupy production equipment, and can be completed quickly after the paper is rewound and before embossing, avoiding the risk of delamination carried over into subsequent continuous production processes. Based on an average daily production of 10 batches and a trial production loss of 5kg of paper per batch, it can reduce raw material loss by approximately 18 tons annually, saving over 100,000 yuan in costs.

[0092] 3. Break away from "single function" and achieve multi-dimensional adaptation to testing scenarios.

[0093] In existing technologies, if it is necessary to inspect paper of different widths and patterns, the entire embossing roller assembly must be replaced (high cost and time-consuming), or it cannot cover the inspection needs of multiple specifications. This device achieves multi-scenario adaptability through modular design: Width adaptation: Multiple uniform mounting holes 14 on the mounting plate 13 can adjust the spacing between the two embossing rollers 7 (adapting to household paper with a width of 100-300mm, covering the mainstream widths of facial tissues, toilet paper, and kitchen paper); Pattern adaptation: The embossing rollers 7 are detachably connected to the telescopic end of the cylinder 5 through the bearing seat. Replacing embossing rollers 7 with different patterns (dots, diamonds, grids) only takes 5 minutes without disassembling other parts, and can inspect the delamination under different pattern pressing (such as grid patterns which require higher pressure to ensure interlayer bonding).

[0094] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
