As shown in fig. 1, an encoder 200 is disposed in the lower roller, the encoder 200 has a function of recording the rotation speed and the rotation time of the roller at the same time, and a hydraulic device 202 is disposed in the upper roller, so that the distance between the upper roller and the lower roller can be adjusted by the hydraulic device 202, and a sufficient clamping force is provided to clamp the wire sample 500.

By arranging the pressure sensor on the roller 201, the contact and separation time point of the roller 201 and the wire sample 500 can be monitored more accurately, so that the accuracy of measuring the length of the wire sample 500 is further improved.
In some exemplary embodiments, in order to further stabilize the wire sample 500, a wire sample guide mechanism (not shown) may be provided at the front end of the roller 201, and the guide mechanism is used for stable input of the wire sample 500, so as to ensure that the wire sample 500 can be centered at the initial stage of biting into the roller 201.

The weighing station 300 is positioned downstream of the clamping mechanism and has a surface dimension that is larger than all of the wire sample 500 to ensure that the weighing station is able to accommodate the wire sample 500.

In some exemplary embodiments, the length of the end face of the cleaning mechanism 301 is the same as the length in the same direction of the weighing station 300.
In some exemplary embodiments, the weight deviation detecting device 100 further includes an alarm 600 and a display system 700, wherein the alarm 600 sends out an alarm signal when the weight deviation of the wire sample exceeds a standard value, and the display system 700 is used for displaying the weight deviation detection result. The alarm 600 and display system 700 are mounted in a conspicuous location, such as at the front end of the wire sample 500 feed. Illustratively, alarm 600 is an audible and visual alarm.
The operation principle of the weight deviation detecting apparatus 100 will be described with reference to fig. 3.
First, the diameter d of the wire sample (in this embodiment, the cross section of the wire sample is circular) is measured, an initial distance d 'between the upper and lower rollers in the clamping mechanism is set according to the wire sample diameter d, wherein d' is smaller than d, and then the rollers 201 are started, and the angular velocities of the upper and lower rollers are v.
The wire sample 500 is put into a guide mechanism (not shown) which transports the wire sample 500 to be slowly fed into a wire sample 500 holding mechanism, the guide mechanism is arranged to be capable of centering the wire sample 500 and the upper and lower rollers, the centering means that the center line of the wire sample 500 and the midpoint of the initial distance d' between the upper and lower rollers are kept on the same horizontal plane, and the centering is previously completed by debugging the device before the operation.
When the end of the wire sample 500 contacts the roller 201 of the clamping mechanism, i.e. the wire sample 500 contacts the roller at point a (see fig. 3(a)), the wire sample 500 applies a force to the roller 201, and a pressure sensor (not shown) on the roller 201 receives a signal, and the encoder 200 starts recording time.
As the guide mechanism continues to feed the wire sample 500, and the wire sample 500 will gradually enter the roller 201 under the rotation of the roller 201, the upper roller will be jacked up until the distance between the upper and lower rollers is the same as the diameter d of the wire sample, since the initial distance d' between the upper and lower rollers is smaller than d, at which point the contact point of the roller 201 and the wire sample 500 rotates from the a position to the B position (i.e., the position of fig. 3 (B)), during which the hydraulic device 202 will provide enough clamping force to clamp the wire sample 500.
In the process that the wire sample 500 bites into the roller 201, the distance traveled by the wire sample 500 is A, B, which is the distance L between two points1When the upper roller rotates at an angle α and the angular velocity of the upper roller is v, the time t for the sample wire 500 to bite into the roller 201 is determined1＝α/v。
As can be seen in FIG. 3(a), L1The distance between the points OA (D/2) and O, B of the roller 201 forms a triangle, and therefore,
the wire sample 500 continues to run under the clamping of the roller 201, when the wire sample 500 is separated from the roller 201, the acting force applied to the roller 201 disappears, the pressure sensor on the roller 201 receives a signal, the calculation of the stroke of the roller 201 is finished, and at the moment, the encoder 200 records the total time length t taken by the wire sample 500 from the contact roller 201 to the separation roller 201.
The state in which the wire sample 500 is out of contact with the roller 201 is shown in fig. 3(c), and the end of the wire sample 500 is tangent to the point of the roller 201 in the vertical direction. The wire sample 500 in this state loses the clamping force of the roller 201 and enters the weighing stage 300 downstream.
From the above analysis, the length of the wire sample 500 is measured in the following mannerTwo stages, the first stage is a stage in which the wire sample 500 bites into the roller 201, and the wire sample 500 travels a distance L between two points A, B1And the second stage is a stable operation stage of the wire rod specimen 500, in which the length L of the wire rod specimen 5002Equal to the length, L, over which the roller 201 rotates2＝(t-t1)vD/2。
And the total length L of the wire sample 500 is L1+L2And therefore, the first and second electrodes are,
then, the wire sample 500 with the measured length enters the weighing platform 300, and the weight w of the wire sample 500 is obtained;
then obtaining the weight deviation delta of the wire sample according to a calculation formula,
wherein, wiIs the theoretical total, i.e. the weight that a sample of wire per unit length should have.
The length L of the wire sample 500 is measured through the roller 201 of the wire sample 500 clamping mechanism, the weight of the wire sample 500 is obtained through the weighing platform 300, and the weight deviation delta is quickly obtained according to a weight deviation data calculation formula of the wire sample 500. In addition, the technical scheme fully considers the problem that the length measurement of the head of the wire sample 500 is inaccurate when the head of the wire sample 500 enters the meshing stage of the roller 201, and a formula is designed in a targeted manner, so that the length L of the wire sample 500 between the meshing stage and the stable operation stage of the wire sample 500 can be calculated1According to this formula, the actual length L of the wire rod specimen 500 can be accurately calculated, thereby improving the accuracy of the overall data.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
