Description

TECHNICAL FIELD

[0001] The utility model relates to coiled material detection technical field, concretely relates to a kind of coiled material quick detection device of realizing quick clamping, multidirectional adjustment and high detection efficiency. BACKGROUND

[0002] In the field of coiled material processing and manufacturing, it is crucial to detect coiled material quickly and accurately to ensure its quality meets production requirements. However, existing coiled material detection devices have some shortcomings, affecting the efficiency and accuracy of detection.

[0003] On the one hand, the transmission mode of existing devices is not stable and reliable, and is prone to slipping or uneven transmission, which causes the rotation speed of coiled material to be unstable during detection, affecting the accuracy and integrity of the detection results. For example, some devices use gear transmission or belt transmission. These transmission modes are difficult to maintain stable transmission effect when facing different specifications of coiled material, especially when the diameter of coiled material is large or small, the transmission efficiency and stability will decrease significantly.

[0004] On the other hand, existing devices have poor adaptability and are difficult to flexibly adapt to the detection needs of coiled material of different diameters and thicknesses. Generally, the structural design of these devices is fixed and cannot be easily adjusted to adapt to coiled material of different specifications, resulting in the need to replace different parts or perform complex adjustments when detecting different coiled material, which is tedious and time-consuming, reducing detection efficiency.

[0005] In addition, the operation efficiency of existing devices is low and the degree of automation is not high. When adjusting the relative position between the drive roller and the coiled material, manual operation is often required, which not only increases labor intensity, but also easily leads to detection errors due to human operation errors. At the same time, the lack of precise forward and backward motion control makes the contact between the drive roller and the coiled material unstable, further affecting the precision and reliability of detection.

[0006] In view of the above problems, the utility model aims to provide a coiled material quick detection device to solve the shortcomings in the prior art and realize stable and reliable transmission, strong adaptability, simple operation and high adjustment precision. UTILITY MODEL CONTENTS

Moreover, the design of friction transmission contact facilitates appropriate adjustment according to different specifications of the material roll, and has strong adaptability. At the same time, by arranging the adjusting assembly, the relative position between the driving roller assembly and the rotating material roller can be flexibly adjusted to adapt to the detection requirements of material rolls with different diameters and thicknesses, and the operation is simple and the adjustment precision is high, greatly improving the versatility and practicality of the device, and also being conducive to maintaining good transmission effect during detection, further improving the detection quality.

[0017] Preferably, the surface of the driving roller is coated with a rubber layer with a friction coefficient greater than 0.5.

[0018] The high-friction rubber layer greatly enhances the friction between the drive roller and the material roll, effectively preventing slipping during transmission, ensuring that the material roll rotates stably and uniformly, and providing more accurate and reliable detection conditions for the detection unit. Secondly, the rubber layer has good wear resistance and corrosion resistance, and can maintain its performance stability during long-term use, and is not easy to wear and age, thereby prolonging the service life of the drive roller and reducing the maintenance cost of the equipment.

The conical matching also has a certain self-locking function, which can maintain good connection stability during rotation, avoiding the connection loosening problem caused by vibration or impact. The axial adjusting block is hinged to the tail end of the rotating abutting shaft, which has high flexibility and adjustability. The quick-detaching air cylinder enables the axial adjusting block to quickly move along the axis direction of the rotating material roller, realizing quick mounting and detaching of the rotating material roller. This design greatly shortens the time for replacing the material roll, improving the working efficiency of the detection device. At the same time, the detachable connection between the piston rod of the quick-detaching air cylinder and the axial adjusting block facilitates the maintenance and maintenance of the equipment, and reduces the use cost of the equipment.

[0029] The elastic return mechanism can provide stable return force, ensuring that the adjusting frame can quickly and accurately return to the initial position during adjustment, improving the response speed and work efficiency of the equipment. The combination of the pre-tightening spring and the guide strut makes the elastic return mechanism have good stability and reliability, which can effectively reduce the position deviation of the adjusting frame caused by external impact or vibration, thereby ensuring the accuracy and stability of the detection. Moreover, the elastic return mechanism has a simple structure, low manufacturing cost and convenient maintenance, which can effectively reduce the overall cost of the equipment.
