Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel cord production technology, and in particular to a wire tension detection device for steel cord production. Background Technology
[0002] Steel cord is made of high-quality high-carbon steel with a brass-plated surface. It consists of fine-gauge steel wire strands or ropes with special uses. It is mainly used as a skeleton material for passenger car tires, light truck tires, heavy truck tires, construction machinery tires, aircraft tires, and other rubber products. The tension of steel cord needs to be tested during its production.
[0003] Traditional tension detection devices have some problems: the tension of steel cord is usually in the range of 50-500N. Directly installing a tension sensor requires cutting the wire to pass through the shaft, which causes the mechanical connection parts (such as flanges) to become stress concentration points, and may break under long-term high tension.
[0004] To address these issues, those skilled in the art have proposed a wire tension testing device for steel cord production. Utility Model Content

Detailed Implementation
[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0033] Example 1
[0034] Reference Figure 1 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a wire tension testing device for steel cord production, which can achieve the effect of indirect and non-contact measurement of steel cord wire tension. It includes a workbench 100, which serves as the basic support structure of the device.
[0035] The wire laying detection mechanism 500 is installed on one side of the workbench 100 and is used to place the steel cord and detect the wire laying tension.
[0036] The take-up mechanism 300 is mounted on the workbench 100 and is used to take up steel cord.
[0037] The laser detection mechanism 400 is set on the workbench 100 between the take-up mechanism 300 and the pay-off detection mechanism 500, and is used to assist in detecting the tension of the steel cord.
[0038] The information processing and display mechanism 200 is installed on the workbench 100 and is used to process and display the test data.
[0039] Specifically, the workbench 100 is elongated, and the wire feeding detection mechanism 500 includes an open box 501. A bearing seat 503 is installed on the top inner wall of the open box 501, and a wire feeding drum 504 is inserted into the circumferential inner wall of the bearing seat 503. The wire feeding drum 504 is vertically located on the surface of the open box 501, and a pressure sensor 502 is installed on the bottom outer wall of the bearing seat 503.
[0040] Furthermore, the information processing and display mechanism 200 includes a fixed column 201, which is installed on the outer wall of the top of the workbench 100 away from the open box 501. A controller is installed inside the fixed column 201, and a display 202 is installed on one outer wall of the fixed column 201. The controller is an integrated controller that is connected to all electrically driven machines inside the device to control the operation of each machine and receive signals from the machines.
[0041] In use, the steel cord is initially wound around the wire release detection mechanism 500. One end of the steel cord is pulled out, straightened, and fixed to the take-up mechanism 300. Then, the take-up mechanism 300 pulls the steel cord horizontally. During the pulling process, the wire release detection mechanism 500 and the laser detection mechanism 400 detect the tension of the steel cord during wire release and transmit the data to the controller, which then displays it on the display instrument 202.
[0042] Example 2
[0043] Reference Figures 1 to 3 This is the second embodiment of the present invention. Unlike the previous embodiment, a rectangular groove 101 is opened in the middle of the surface of the workbench 100, and the moving component is installed inside the rectangular groove 101.
[0044] Specifically, the moving component includes an electric slide rail 102, which is horizontally mounted on the inner wall of the rectangular groove 101, and a slider 103 is slidably disposed on the surface of the electric slide rail 102.
[0045] Furthermore, the take-up mechanism 300 includes a base 301, which is fixedly installed on the top outer wall of the slider 103. A housing 302 is installed on the surface of the base 301. A drive assembly is provided inside the housing 302. A take-up drum 303 is installed at one end of the drive assembly. The take-up drum 303 is vertically located above the housing 302 and is at the same height as the unwinding drum 504.
[0046] The drive assembly includes a variable frequency motor 304 and a damping brake 305. The variable frequency motor 304 is mounted on the bottom inner wall of the housing 302. The damping brake 305 is connected to one end of the output shaft of the variable frequency motor 304 via a coupling. The take-up drum 303 is mounted on one end of the damping brake 305.
[0047] It should be noted that an arc-shaped groove 3031 is opened on one side of the outer wall of the take-up drum 303, and an electric cylinder 3032 is installed on the outer side of the surface of the take-up drum 303 near the arc-shaped groove 3031. An arc-shaped pressure plate 3033 is installed at one end of the electric cylinder 3032.
[0048] In use, the end of the steel cord pulled out is clamped and fixed in the arc groove 3031 of the take-up drum 303. Then, the electric cylinder 3032 is activated, and the arc pressure plate 3033 is used to press and fix the steel cord, which facilitates fixing the head of the steel cord. This allows the steel cord on the pay-off drum 504 to be wound around the surface of the take-up drum 303 during the pulling process. The electric slide rail 102 is activated to drive the slider 103 to move, which facilitates changing the distance between the take-up mechanism 300 and the pay-off detection mechanism 500. Multiple sets of experimental tests are conducted according to different distances to avoid the randomness of the experimental results. The steel cord is pulled by the variable frequency motor 304 and the damping brake 305. The variable frequency motor 304 can change the speed, and the damping brake 305 is used to adjust the take-up tension.
[0049] Example 3
[0050] Reference Figures 1 to 4 This is the third embodiment of the present invention. Unlike the previous embodiment, the worktable 100 has a strip groove 104 on the outer wall of one side near the rectangular groove 101. The laser detection mechanism 400 includes an electric slide rail 407, which is horizontally arranged inside the strip groove 104. A sliding sleeve 408 is slidably arranged on one side of the outer wall of the electric slide rail 407, and a connecting plate 401 is installed on one side of the outer wall of the sliding sleeve 408.
[0051] The surface of the connecting plate 401 is provided with two inclined support seats 402. Electric cylinders 403 are installed on the surface of both support seats 402. Folded plates 404 are installed on the surface of both electric cylinders 403. Laser emitters 405 and laser receivers 406 are respectively installed on the outer wall of the opposite side of the two folded plates 404.
[0052] During use, the steel cord is released from the release drum 504 of the release detection mechanism 500. The initial end is fixed by the arc-shaped groove 3031 on the take-up drum 303 of the take-up mechanism 300 and the arc-shaped pressure plate 3033 driven by the electric cylinder 3032. The variable frequency motor 304 drives the take-up drum 303 to rotate and wind up the steel cord. The damping brake 305 assists in adjusting the take-up tension. During the release process, the tension of the steel cord is transmitted to the bearing seat 503 through the release drum 504. The pressure sensor 502 below the bearing seat 503 detects the pressure change and converts it into a tension signal. At the same time, the steel cord passes through the laser detection mechanism 400, and the laser emitter 405 emits a laser beam to irradiate the steel cord. The laser receiver 406 receives reflected light and calculates tension by detecting the deformation of the steel cord. The detection data from the pressure sensor 502 and the laser detection mechanism 400 are transmitted to the display instrument 202 of the information processing and display mechanism 200 for processing and display. When the tension is abnormal, the control system adjusts the speed of the variable frequency motor 304 and the braking force of the damping brake 305 according to the data. At the same time, the electric cylinder 403 can adjust the height of the laser emitter 405 and the laser receiver 406 to adapt to the height fluctuation of the steel cord and ensure tension stability. The electric slide rail 102 and the slider 103 on the worktable 100 can adjust the position of the take-up mechanism 300 to meet different detection requirements.
[0053] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
