The reference anvil is slidably placed inside the base, with a pull rod fixedly connected to the front of the reference anvil. A display screen is fixedly connected to the right side of the base, and a mounting block is fixedly connected to the top of the base. A dial indicator is fixedly connected to the front of the mounting block, with a probe at the bottom of the dial indicator. The dial indicator is electrically connected to the display screen. Fixing rods are fixedly connected to both sides inside the base. This utility model utilizes the principle of levers to amplify the displacement of the tissue paper thickness at the end of the long lever arm, as the measuring indenter descends under the weight of the weight.

This completely avoids measurement errors caused by lateral offset or swaying. The minute displacement caused by the tissue paper thickness is transmitted to the main lever through the connector, and the displacement is amplified at the end of the long lever arm.

Description

Technical Field

[0001] This utility model relates to the field of tissue paper detection technology, and in particular to a tissue paper thickness detection device. Background Technology

[0002] Paper towels are soft, highly absorbent, disposable thin paper products made primarily from wood pulp, bamboo pulp, or recycled fibers through processes such as hydrolysis, bleaching, pulping, papermaking, drying, and slitting. They are widely used for daily cleaning, wiping, and hygiene protection. Based on their uses, they can be categorized into facial tissues, napkins, handkerchiefs, and kitchen paper towels, and are characterized by being non-toxic, non-irritating, and easily biodegradable.

[0003] In the production of tissue paper, thickness is a core quality indicator that directly affects the product's softness, absorbency, stiffness, and consumer experience. It is also a crucial parameter for measuring the stability and consistency of the production process. However, most tissue paper manufacturers currently rely on handheld thickness gauges or mechanical micrometers for offline sampling inspections. Operators must periodically cut samples from the high-speed production line, manually place them under the measuring head, apply pressure, read the values, and manually record the data. This entire process is time-consuming and inefficient, failing to match the operating speed of modern tissue paper production lines (hundreds of meters per minute), resulting in insufficient sampling frequency and an inability to achieve real-time monitoring and timely intervention of thickness fluctuations. Furthermore, the pressure applied by different operators varies, and since tissue paper is a highly fluffy and compressible material, even small pressure changes can cause significant deviations in thickness readings, leading to data distortion.

[0004] Therefore, it is necessary to design a tissue thickness detection device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of paper towel production, where thickness is a key indicator affecting softness, absorbency, and user experience, current methods mostly rely on handheld thickness gauges or micrometers for offline sampling. These methods require manual sampling, pressure application, reading, and recording, resulting in low efficiency, low frequency, and difficulty in matching high-speed production lines. Furthermore, because paper towels are fluffy and easily compressed, uneven manual pressure can easily lead to measurement deviations and poor data reliability. Therefore, this utility model provides a paper towel thickness detection device.

[0006] The technical implementation scheme of this utility model is as follows: a paper towel thickness detection device includes a base, a reference cutting board, a pull rod, a display screen, a mounting block, a dial indicator, a fixed rod, a main lever, a connector, a measuring pressure head, a push block, and a guide assembly. The reference cutting board is slidably placed inside the base. A pull rod is fixedly connected to the front of the reference cutting board. A display screen is fixedly connected to the right side of the base. A mounting block is fixedly connected to the top of the base. A dial indicator is fixedly connected to the front of the mounting block. A measuring pressure head is fixedly connected to the bottom of the dial indicator. The dial indicator is electrically connected to the display screen. Fixed rods are fixedly connected to both sides inside the base. A main lever is rotatably connected between one side of the two fixed rods. A connector is rotatably connected to the front of the main lever. A measuring pressure head is fixedly connected to the bottom of the connector. A push block is fixedly connected to the front of the connector. A guide assembly is provided between the two fixed rods.

[0007] More preferably, the top of the main lever is in contact with the probe.

[0008] More preferably, the guide assembly includes a connecting frame, a guide block, a guide slide rod, a placement column, and a placement seat. The top of each of the two fixed rods is fixedly connected to the connecting frame, and the two connecting frames are slidably connected to one side. The top of the connecting head is fixedly connected to the guide slide rod, and the two sides of the middle of the guide slide rod are fixedly provided with protruding columns. A slot is opened on one side of each of the two guide blocks, and the two protruding columns slide in the corresponding slots. The top of the guide slide rod is fixedly connected to the placement column, and the right side of the base is fixedly connected to the placement seat. Multiple weights are slidably placed on the outside of the placement seat and the placement column.

[0009] More preferably, it also includes adapter blocks, rotating shafts, pressure plates, torsion springs, and levers. Adapter blocks are symmetrically fixedly connected to both sides of the top of the reference anvil. Rotating shafts are rotatably connected between the two adapter blocks on the same side. Pressure plates are fixedly connected to one side of each rotating shaft. Both pressure plates abut against the reference anvil. Torsion springs are connected between each rotating shaft and the corresponding adapter block on one side. Levers are fixedly connected to each rotating shaft through the corresponding adapter block on one side.

[0010] Even more preferably, both pressure plates are made of transparent material.

[0011] More preferably, it also includes screws, threaded sleeves, knobs, abutment blocks, and a universal bubble level. Screws are symmetrically fixedly connected to both sides of the bottom of the base. Threaded sleeves are threadedly connected to the outside of each of the four screws. Knobs are fixedly fitted to the outside of each of the four threaded sleeves. Abutment blocks are rotatably connected to the bottom of each of the four threaded sleeves. A universal bubble level is fixedly connected to the right side of the base.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This utility model measures the pressure head as it descends under the weight of the weight. The combination of the connector and the guide slide is strictly constrained by the guide block and its internal slot, ensuring that the pressure head can only move vertically. This completely avoids measurement errors caused by lateral offset or shaking. The minute displacement caused by the thickness of the paper towel is transmitted to the main lever through the connector. The lever principle is used to amplify this displacement at the end of the long lever arm and drive the probe of the dial indicator. The mechanical amplification and transmission, combined with the high precision of the dial indicator itself, can sensitively capture and display thickness changes at the micron level. This makes the measurement of the compressed thickness of fluffy paper towels both accurate and intuitive, and the data reliability is far higher than that of traditional methods that rely on touch and visual inspection.

[0013] 2. This utility model achieves one-click clamping and release of tissue paper samples by quickly sliding out the reference anvil with a pull rod during the sample processing stage, and by using a pressure plate with torsion spring and a lever mechanism. This process only takes a few seconds, which is significantly more efficient than traditional manual placement and support.

[0014] 3. This utility model ensures that when the measuring head descends under the weight of the weight, the combination of the connector and the guide slide is strictly constrained by the guide block and its internal slot, ensuring that the measuring head can only move vertically, thus completely avoiding measurement errors caused by lateral offset or shaking.

[0022] A tissue thickness detection device, such as Figures 1-6 As shown, the system includes a base 1, a reference anvil 2, a pull rod 3, a display screen 4, a mounting block 5, a dial indicator 6, a fixing rod 7, a main lever 8, a connector 9, a measuring pressure head 10, a push block 11, a connecting frame 12, a guide block 13, a guide slide rod 14, a placement column 15, and a placement seat 16. The reference anvil 2 is slidably placed on the bottom side inside the base 1. The pull rod 3 is welded to the front side of the reference anvil 2. The display screen 4 is mounted on the front right side of the base 1 via screws. The mounting block 5 is welded to the rear top of the base 1. The dial indicator 6 is mounted on the front side of the mounting block 5 via screws. The dial indicator 6 has a measuring head on its bottom side and is electrically connected to the display screen 4. Fixing rods 7 are welded to both the left and right sides inside the base 1. The main lever is rotatably connected between the two fixing rods 7 on their closest sides. 8. The top rear side of the main lever 8 abuts against the probe. The front end of the main lever 8 is rotatably connected to the connector 9. The bottom end of the connector 9 is screwed to install the measuring pressure head 10. The front end of the connector 9 is welded to the push block 11. The top sides of the two fixed rods 7 are welded to the connecting frame 12. The two connecting frames 12 are slidably connected to the side of each other. The top side of the connector 9 is welded to the guide slide rod 14. The left and right sides of the middle of the guide slide rod 14 are fixed with protruding pillars. The side of each of the two guide blocks 13 is opened with a slot. The two protruding pillars slide in the corresponding slot. The top side of the guide slide rod 14 is welded to the placement column 15. The rear right side of the base 1 is screwed to install the placement seat 16. Multiple weights are slidably placed on the outside of the placement seat 16 and the placement column 15.

[0023] like Figure 1 and Figure 5As shown, it also includes a connecting block 17, a rotating shaft 18, a pressure plate 19, a torsion spring 20, and a lever 21. The top left and right sides of the reference cutting board 2 are symmetrically welded with connecting blocks 17. The two connecting blocks 17 on the same left and right sides are rotatably connected to the rotating shaft 18. The side of the two rotating shafts 18 that are close to each other is fixedly connected to the pressure plate 19. The two pressure plates 19 are made of transparent material, which makes it easy to observe the position and flatness of the paper towel. The two pressure plates 19 are in contact with the reference cutting board 2. The two rotating shafts 18 are connected to the corresponding connecting block 17 on the front side with a torsion spring 20. The two rotating shafts 18 pass through the corresponding connecting block 17 on the front side and are welded with a lever 21.

[0024] like Figure 1 and Figure 6 As shown, it also includes screws 22, threaded sleeves 23, knobs 24, abutment blocks 25, and a universal bubble level 26. Screws 22 are symmetrically fixed to the front and rear sides of the bottom of the base 1. Threaded sleeves 23 are threadedly connected to the outer sides of the four screws 22. Knobs 24 are fixedly fitted on the outer sides of the four threaded sleeves 23. Abutment blocks 25 are rotatably connected to the bottom sides of the four threaded sleeves 23. A universal bubble level 26 is fixedly connected to the front right side of the base 1.

[0025] When using this device, the operator should first observe the universal bubble level 26 to determine if the base 1 is level. If not, rotate the four knobs 24 to rotate the threaded sleeve 23 on the screw 22, thereby adjusting the height of the four abutment blocks 25 relative to the base 1 until the bubble level is centered, ensuring the entire measurement reference surface is level, laying the foundation for subsequent accurate measurements. After leveling, the operator pulls the lever 3 forward to slide the reference anvil 2 out of the base 1. Then, the operator rotates the two levers 21, which drive the rotating shaft 18 to rotate, overcoming the torque of the torsion spring 20, causing the two transparent pressure plates 19 to rotate and open. The tissue sample to be tested is then placed flat in the center of the reference anvil 2. The operator then releases the levers 21, and under the reset action of the torsion spring 20, the rotating shaft 18 rotates in the opposite direction, causing the two pressure plates 19 to rotate in the opposite direction and press tightly against the edge of the tissue, achieving quick, reliable, and unobstructed sample fixation.

[0026] After the sample is fixed, the operator pushes the lever 3 back, returning the reference cutting board 2, which carries the paper towel, to the base 1 and ensuring it is directly below the measuring pressure head 10. Then, according to the required measuring pressure, the corresponding number of weights are placed on the placement column 15. The weight's gravity is transmitted to the measuring pressure head 10 through the placement column 15, guide slide 14, and connector 9, providing a stable and quantifiable downward pressure. When the measuring pressure head 10 moves downward under the weight of the weights, the connector 9 descends accordingly, the guide slide 14 moves downward synchronously, and the guide block 13 moves downward. Because the main lever 8 moves in an arc trajectory, the protrusions on both sides slide vertically backward within the slot of the guide block 13. The core function of this guiding component is to forcibly constrain the connector 9 and the measuring pressure head 10 to only perform strictly vertical movements, effectively preventing any directional deviation or... To ensure measurement accuracy, the measuring pressure head 10 contacts and presses down on the paper towel sample. Due to the thickness of the paper towel, it exerts an upward reaction force on the measuring pressure head 10, preventing it from descending further. This reaction force makes the fixed rod 7 a fulcrum, pushing the rear end of the main lever 8 to tilt slightly upward. According to the lever principle, the long lever arm of the main lever 8 will generate an amplified, precise upward displacement. The top of the rear end of the main lever 8 is in contact with the probe of the dial indicator 6. Therefore, this amplified displacement is directly transmitted to the probe of the dial indicator 6. The high-precision gear mechanism inside the dial indicator 6 converts this mechanical displacement into the rotation of the pointer on the dial, thus displaying the reading intuitively. At the same time, the dial indicator 6 transmits the displacement signal at this moment to the display screen 4 through an electrical connection, where it is digitally displayed and recorded for easy reading and data retention by the operator.

[0027] After the measurement, the operator first removes all the weights from the placement column 15 and places them in the placement seat 16, removing the load applied to the measurement system. At this time, the upward reaction force of the paper towel sample on the measuring pressure head 10 disappears, the system loses balance, and pushes the push block 11, causing the main lever 8 to swing clockwise, thereby pulling the measuring pressure head 10 away from the surface of the paper towel sample; at the same time, the guide slide rod 14 and the guide block 13 move upward synchronously, and the protrusions on both sides of the main lever 8 slide forward vertically in the slot of the guide block 13. The entire movement is still strictly constrained to a vertical path to avoid If the device shakes or gets stuck, the measuring head 10 will eventually return to its initial high position, the main lever 8 will return to a horizontal and stationary state, and its rear end will re-establish stable contact with the dial indicator 6 probe without additional pressure. The pointer of the dial indicator 6 will return to zero or return to the reference position. Pull the lever 3 forward to slide out the reference anvil 2, and rotate the lever 21 again to open the pressure plate 19. The measured paper towel sample can then be taken out, completing one complete work cycle. The components of the entire device are ingeniously designed and work together to achieve full mechanization and high precision from sample preparation, precise positioning, constant pressure measurement to data reading.
