[0006] Preferably, the execution end of the driving part passes through the take-up drum, and a key cooperating with the take-up drum is provided along the length direction, so that the take-up drum rotates synchronously with the execution end of the driving part and moves downward or has a tendency to move downward under the action of its own gravity.

[0010] Preferably, the beam collector is further provided with an extension portion, and the extension portion is provided as a spindle-shaped structure and has an axis coinciding with the through hole.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0021] like Figure 1 and Figure 2 As shown, a wire drawing equipment wire length measuring device is used to measure the length of the wire material drawn out of the wire drawing machine. It includes a base 1, a driving motor 2 is installed below the base 1, and the execution end of the driving motor 2 is coaxially connected to a take-up drum 3, and the outer edge surface of the take-up drum 3 constitutes the winding surface of the wire material. One end of the wire material is fixed on the winding surface, and the driving motor 2 drives the take-up drum 3 to rotate around its own axis, so that the wire material is wound on the winding surface.

[0022] The base 1 is provided with a measuring mechanism between the wire drawing machine and the wire take-up reel 3, and the measuring mechanism includes a first measuring unit 4. In this embodiment, the first measuring unit 4 adopts an encoder. When the wire passes through the first measuring unit 4 during the drawing process, the first measuring unit 4 records the length of the wire.

[0023] Specifically, a carrying platform 6 is provided on the base 1, and the carrying platform 6 is arranged as a horizontal C-shaped structure, a groove is formed in the middle for installing the first measuring unit 4, and the walls protruding on both sides play a role in protecting the first measuring unit 4, and the wire material passes through the first measuring unit 4 in a direction perpendicular to the plane where the carrying platform 6 is located.

[0024] like Figure 4 As shown, a beam collector 7 is installed between the mounting platform 6 and the take-up reel 3 on the base 1. The beam collector 7 includes a support seat 73 fixed to the base 1. A through hole 72 is provided at the top of the support seat 73 in the horizontal direction. The through hole 72 is for the wire to pass through. At the same time, the through hole 72 has a diameter corresponding to the wire, thereby limiting the error caused by the vibration of the wire brought to the wire by the operation of the take-up reel 3 to the measurement of the measuring mechanism to a certain extent. In addition, an extension portion 71 coaxial with the through hole 72 is provided at the top of the support seat 73. The extension portion 71 is set to a simulated conical structure, which further limits the vibration of the wire along its own diameter direction.

[0025] Because the wire is thin or smooth, the length measured by the encoder is prone to deviation, resulting in inaccurate calculation of the wire length. In order to ensure the accuracy of the measurement result, a second measuring unit 5 is also provided. The second measuring unit 5 includes a laser diameter measuring device 51 installed on the mounting platform 6, and a weighing part 52 installed on the base 1 and located at the bottom of the take-up reel 3.

[0026] The weighing unit 52 can directly weigh the weight of the wire material under the premise that the mass of the wire reel 3 is known. Combined with the wire diameter obtained by the laser diameter measuring device 51, the length of the wire material drawn out of the wire drawing machine can be obtained under the action of the processing unit, and the calculation result is compared with the measurement result of the first measuring unit 4 for comprehensive evaluation to avoid errors caused by a single measurement method.

[0027] Specifically, the execution end of the driving motor 2 passes through the take-up drum 3, and a key is provided along the length direction, and a key slot is provided corresponding to the key through the take-up drum 3. The take-up drum 3 rotates synchronously with the execution end of the driving motor 2, while retaining the freedom to move downward under the action of its own gravity.

[0028] like Figure 3 As shown, the weighing part 52 includes a weighing seat 521 and a pressure sensor 522. In this embodiment, the pressure sensor 522 has four detection ends fixed on the base 1 and evenly arranged around the axis of the take-up reel 3. The top of the weighing seat 521 supports the take-up reel 3, and the bottom is connected to the detection ends of the four pressure sensors 522.

[0029] When working:

[0030] 1. The wire is drawn out from the wire drawing machine, passes through the first measuring unit 4, the laser diameter measuring device 51 and the beam collector 7, and is then connected to the take-up reel 3.

[0031] 2. The drive motor 2 drives the take-up reel 3 to rotate, and the wire is continuously drawn out of the wire drawing machine. At the same time, the encoder records the length of the wire passing through itself, the laser diameter measuring device 51 records the diameter of the wire, and the weighing unit 52 records the weight of the wire on the take-up reel 3.

[0032] 3. The processing unit obtains the length of the wire in real time according to the weight and diameter of the wire, and compares it with the length recorded by the first measuring unit 4. If a small error is obtained, it means that the measurement of the wire length is accurate.

[0033] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
