[0002] With the rapid development of China's aerospace technology, the outer skin, wall panels, cabin door skeletons, etc. of aircraft all use composite materials to replace metal materials. Since the raw materials of composite materials and their related auxiliary materials are mostly stored in the form of drum coils, their usage methods are all to fix the drum with a bracket and extract enough length of raw materials manually or by equipment. However, when taking materials manually, there is a lack of accurate reference for the length. In order to ensure sufficient length, a large margin is often taken, resulting in unnecessary waste of materials worth thousands of yuan per square meter. Content of the Utility Model

[0019] Figure 1 It is a schematic structural diagram of a metering tool for a scrolling thread. Detailed implementation manners

[0020] The present utility model provides a metering tool for a scrolling thread, as Figure 1 shown, including: a stable bracket 1, a rolling measurement device 2, a placement rack 3, and a coil 4;

[0021] Among them, the placement rack is inserted into the central hole of the coil to support and suspend the coil; the rolling measurement device is installed on the placement rack through the stable bracket 1, and the rolling measurement device clamps the extracted sheet to measure the scrolling thread of the sheet.

[0022] The rolling measurement device 2 includes two damping rollers 21 and a measuring device 22;

[0023] The two damping rollers are arranged vertically. The lower damping roller 212 is fixedly connected to the input shaft of the measuring device. The upper damping roller 211 is installed on the housing of the measuring device and can be adjusted vertically to change the gap with the lower damping roller; after the sheet is extracted, it passes through the gap between the two damping rollers, driving the upper and lower damping rollers to rotate, so that the measuring device can record the number of rotations of the damping rollers, thereby determining the scrolling thread of the sheet.

[0024] The damping rollers can be completely parallel and attached to the outer surface of the coiled material sheet.

[0025] Preferably, the damping rollers are rubber damping rollers.

[0026] The lower damping roller is installed with a magnet;

[0027] The measuring device 22 includes: a switch 221, a zeroing button 222, a housing 223, a display 224, a magnetic sensor, and a processor;

[0028] The magnetic sensor, the processor, and the display are located inside the housing. The scrolling thread displayed on the display is shown through the window of the housing. The switch and the zeroing button are connected to the processor and are used to send corresponding instructions to the controller under the pressing operation of the user. The magnetic sensor is used to sense the magnet and send the sensing result to the processor. The processor determines the scrolling thread of the sheet according to the sensing result.

[0029] The stabilizing brackets are fixed at both ends of the crossbar of the placement rack.

[0030] The rolling measurement device includes: a housing, an LCD display screen, a switch button, a zeroing button, a magnetic sensor, a fixed-axis rubber damping roller for installing the magnet, a clamping rubber damping roller, a clamping spring, a moving guide rod for the clamping rubber damping roller, a micro power supply, and a stabilizing bracket.

[0031] When in use, install the measuring tool on the stabilizing bracket. The stabilizing bracket is fixed at both ends of the crossbar of the placement rack. Draw out the sheet so that it passes through the gap between the two rubber rollers. The rubber damping rollers can be completely parallel and fit on the outer surface of the coiled sheet. Among them, the pressing rubber damping roller has an elastic movement range of 3 mm and is pulled by the pressing spring to adapt to coiled sheets of different thicknesses.

[0032] After installation, press the switch to start the tool and press the zeroing button to initialize the reading. Draw out the sheet and use the friction of the rubber damping rollers to drive the rollers to rotate. Among them, the fixed rubber roller installed with the magnet makes the magnet rotate together during rotation. The length of each rotation is the circumference of the roller. The built-in magnetic inductor senses the number of turns the magnet has rotated, and the length of the coiled sheet drawn out can be obtained through calculation.

[0033] When the current blanking is over, press the zeroing button to zero the reading, and then it can be used next time.

[0034] Embodiment 1

[0035] After the coiled material is placed on the placement rack, slip the two ends of the stabilizing bracket onto both sides of the crossbar of the placement rack respectively;

[0036] After fixing the measuring tool, slide the measuring tool to a suitable position on the stabilizing bracket so that after the coiled material is drawn out, it passes through between the two rubber damping rollers. The rubber damping rollers can be completely parallel and fit on the outer surface of the coiled sheet;

[0037] Press the switch to start the measuring tool;

[0038] Press the zeroing button to zero the reading;

[0039] When taking materials, pulling the material sheet will drive the rubber damping roller with a magnet to rotate. The length of one turn of the magnet rotation is the perimeter of the cross-section of the damping roller, and this data can be quantified. Then, the number of times the magnet rotation is sensed by the magnetic inductor can be converted into the material extraction length, completing the measurement of the rolling thread of the coil material.

[0040] After pressing the zero button, the next measurement can be carried out.
