Description

Technical Field

[0002] Thickness detection is often an important part of quality inspection in the production process of synthetic leather, which can affect the performance, durability and appearance of the final product. The current detection methods are caliper method, pressure method and laser scanning method. The laser scanning method calculates the thickness of the leather through a laser measuring instrument.

[0003] For example, the Chinese patent of prior art 1 (publication number CN118392103A) discloses an online leather thickness detection device, including a detection frame and a conveying mechanism; a dual detection component is installed on the detection frame, and the dual detection component is used to detect the thickness of the leather; the dual detection component includes a laser probe and a pressure probe; the data measured by the laser probe and the data measured by the pressure probe can be referenced and supplemented with each other, thereby improving the accuracy of leather thickness detection, wherein the laser probe measures the leather many times and has a wide measurement range, thereby realizing a comprehensive measurement of the leather thickness, and being able to determine the thickness value of the leather when it is not under pressure, while the pressure probe performs random inspections on the leather and performs a pressure method test on the local thickness of the leather, and under the action of pressure, reduces the measurement error caused by factors such as elasticity and deformation, thereby improving the accuracy of leather thickness measurement; When the above technology is used to measure the thickness of synthetic leather, the pressure on the synthetic leather is likely to cause damage to the material, which is not conducive to ensuring the integrity of the material when the user uses it. In order to overcome the above shortcomings, the Chinese patent of prior art 2 (Announcement No. CN219083965U) discloses a leather product thickness detection tool, including a fixed base, the top center of the fixed base is fixedly connected to a pressing plate, and the rear end of the pressing plate is fixedly connected to a support frame; a stamping cylinder is installed at the top center of the support frame, and the bottom of the stamping cylinder piston rod is fixedly connected to a buffer mechanism, and the bottom of the buffer mechanism is fixedly connected to a stamping plate; a limited position slide groove is provided at the rear end center of the support frame, and a measuring mechanism is provided between the stamping plate and the support frame. By designing a simple buffer mechanism, when the stamping mechanism is in a stable reciprocating motion, the buffer mechanism can achieve the buffering purpose for it, thereby reducing the large direct pressure, providing protection for the equipment, and avoiding excessive pressure from causing dents to the leather products.

[0004] Although the prior art can overcome the above-mentioned deficiencies, there are still other problems in its operation. For example, when measuring the downward pressure, if there are debris impurities, the surface of the synthetic leather may be easily damaged due to the debris when the pressure is measured, which may easily cause material loss, hindering the subsequent use of materials by the staff and causing a waste. Summary of the invention

In this way, more data is collected, making the detection data more accurate and improving the detection effect. Furthermore, after the contact platform contacts the synthetic leather body, the contact platform pushes the movable plate upward through the movable column, and the movable plate squeezes the buffer spring inside the fixed bin to buffer the compression force. Combined with the setting of the damping rod, the synthetic leather body can be prevented from being compressed and deformed, and at the same time, the thickness measurement effect can be made more accurate, thereby improving the accuracy of detection.

[0017] 2. When the lifting platform moves downward to measure the synthetic leather body, the pressure plate at the rear end descends with the descent of the lifting platform, so that the pressure plate slides along the limiting groove on the fixed plate through the limiting block, and the air jet is aimed at the impurities on the surface of the synthetic leather body to blow away. It can be recycled to avoid impurities from damaging the surface of the synthetic leather body during the thickness detection of the synthetic leather, thereby ensuring the integrity of the synthetic leather after the thickness detection.

[0018] 3. Before the thickness test, remove the positioning bolt and turn the second adjustment handle. When the second adjustment handle is turned, the cleaning brush at the lower end of the push plate moves with the push plate, and under the pressure of the pressure spring, it sweeps away the impurities on the surface of the testing platform to avoid the bottom of the synthetic leather body being damaged due to impurities during the test; Furthermore, when the synthetic leather body needs to be taken out, by loosening the second adjustment handle, the push plate moves toward the front end along the inside of the card bin under the action of the movable spring, so that the synthetic leather body can be easily taken out, which makes it easy to take out the synthetic leather body and facilitates the use of the staff. There is no need for the staff to put their hands into the device, avoiding the occurrence of safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
