The vacuum suction pump 56 is connected to the weighing scale 59 through an automatic control system to realize automatic data collection and processing, thereby improving the automation of the entire detection system.

[0086] After the suction and transportation operation of the broken fiber at the bottom is completed, the electric push rod 38 is controlled to start, and the electric push rod 38 pushes the push-pull frame 39 to drive the fitting wind hood 311 and stretch the corrugated guide tube 310 to deform, so that the fitting wind hood 311 can be fitted to the surface of the vacuum suction hood 57 again, so that it forms an air suction channel again, and then the telescopic cylinder 314 on the surface of the upper clamp 313 is controlled to release the clamping of the fiber, and then the shearing cylinder 45 is started, and the shearing cylinder 45 pushes the shearing slide 46 to slide along the surface of the support seat 47, so that the spring 2 48 can be squeezed to deform and generate elastic force, thereby driving the push-pull rod 410 to push the shear knife 49 through the push-pull groove to flip inside the support seat 47, so that the fiber can be automatically cut, without the need for manual complex operations, reducing the difficulty of the operator's work, making the entire detection process more concise and efficient, and can timely remove broken fibers, ensuring that each detection is carried out in a clean and interference-free environment, thereby ensuring the accuracy and reliability of the detection results;

[0087] The cut fibers will also fall into the interior of the corrugated guide tube 310 under the action of the suction hood 312, and then the cut fibers will be finally transported to the interior of the weighing scale 59 along a predetermined path under the directional channel provided by the corrugated guide tube 310, thereby ensuring that each section of broken fiber can accurately enter the weighing scale 59, avoiding the cut fibers from falling and not being able to fall into the weighing scale 59, resulting in missing measurement data, thereby ensuring that the strength test data is based on all fiber materials, improving the integrity and reliability of the data, and eliminating the need to spend extra time and energy to find and capture the falling fibers and put them into the electronic scale, and the corrugated guide tube 310 can effectively shield environmental factors. Interference can reduce the impact of the surrounding environment to a certain extent, and avoid the absorption of dust and impurities in the air during the falling process of the fiber. These additional substances will affect the actual weight measurement of the fiber, reduce unnecessary contact with the external environment, thereby reducing the possibility of impurity absorption, and make the measurement result more accurately reflect the weight of the fiber itself, providing a more accurate data basis for strength detection. When all the fibers fall into the balance, the weighing data can be read and the data can be summarized and saved. After calculation, the fiber strength detection data can be obtained. The motor, electric rod and clamp in the device are preferably servo-controlled, and each device is controlled by PLC, encoder and solenoid valve, and feedback is provided by each component.

[0088] The present invention also provides a working method of an automatic tensile meter length and weight detection device, comprising the following steps:

[0089] S1. First, the fiber bobbin is fixed on the pay-off section 7, and the pay-off section 7 drives the pay-off. S2. Then, the lower clamp 321 of the stretching assembly 6 is driven to the position of the limit switch 512. The lower clamp 321 fixes one end of the fiber, and then the stretching assembly 6 drives one end of the fiber to move to the detection position, and the upper clamp 313 fixes the other end of the fiber. S3. Then, the stretching assembly 6 is driven to perform a fiber strength test until the force sensor 322 produces a peak force and the fiber breaks. At the same time, the force sensor 322 receives the tensile force of the fiber and feeds it back to the control system, which records it. S4. Then, the guiding assembly 8 moves to the bottom of the fiber, the vacuum suction pump 56 of the adsorption section 3 is turned on, and the fiber is straightened by the airflow of the vacuum suction pump 56. The shearing assembly 4 is driven to cut the fiber. S5. Finally, the fiber is adsorbed to the weighing assembly 5 for weighing, and the weighing assembly 5 feeds back the weighing data to the control system.

[0090] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
