Description

Technical Field

[0001] This utility model relates to the technical field of mining W-shaped steel strip production line, specifically to an automatic length measuring and counting device for a data wheel used in mining W-shaped steel strip production line. Background Technology

[0002] Mining W-shaped steel strips (also called roof steel strips) are mainly used for coal mine roadway support and belong to the alloy steel strip category. Currently, mining W-shaped steel strips are mainly processed and produced through production lines, which significantly improves the production efficiency of mining W-shaped steel strips, and the production line technology is relatively mature and widely used.

[0003] Length measurement is a core inspection function of the production line, providing crucial data support for dimensional accuracy control in each process and serving as a fundamental link in ensuring consistent product quality. Currently, the length measurement scheme used in W-shaped steel strip production lines primarily calculates length based on the product of conveying speed (including preset parameters or real-time detection values) and conveying time. This scheme boasts advantages such as simple principle, low hardware deployment cost, and easy engineering implementation. However, in actual production applications, factors such as production line layout, multi-transmission unit coordination errors, steel strip tension fluctuations, and differences in material surface conditions cause the actual conveying process of W-shaped steel strips to exhibit non-uniform motion characteristics. This leads to a deviation between the reference speed used for length calculation and the actual running speed of the steel strip, resulting in systematic and random errors in length measurement, making it difficult to meet the stringent dimensional inspection requirements of high-precision production. Therefore, it is necessary to optimize and upgrade the length measurement technology for W-shaped steel strip production lines. By improving the detection principle and optimizing the algorithm model, the impact of non-uniform motion on measurement accuracy can be reduced, improving the accuracy and stability of length detection and providing technical support for precise control of the production process and improvement of product quality.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide an automatic length measuring and counting device for a data wheel in a mining W-shaped steel strip production line. The device has advantages such as a feasible and reasonable structural design, good synchronization with the W-shaped steel strip, real-time acquisition of length data, and accurate length measurement.

[0006] The present invention achieves the above objectives by adopting the following technical solutions: An automatic length measuring and counting device for W-shaped steel strip production lines in mining includes a data wheel assembly and a material support roller assembly arranged at intervals from top to bottom on the production line frame. The W-shaped steel strip passes between the data wheel assembly and the material support roller assembly. The material support roller assembly includes a rotatable material support roller main shaft, on which two inverted V-shaped material support rollers are spaced apart. The data wheel assembly includes a rotatable data wheel main shaft, on which two data wheels are spaced apart. The data wheels press against the W-shaped steel strip. One end of the data wheel main shaft is connected to an encoder via a coupling, and the encoder is connected to a controller.

[0007] The production line frame is vertically equipped with a slide groove, on which a data wheel slide plate and a material support roller slide plate are respectively mounted. A data wheel adjusting bolt is located at the upper end of the slide groove, acting on the upper end of the data wheel slide plate. A material support roller adjusting bolt is located at the lower end of the slide groove, acting on the lower end of the material support roller slide plate. A limiting block is provided between the data wheel slide plate and the material support roller slide plate. The two ends of the data wheel main shaft are rotatably mounted on the data wheel slide plate via bearings. One of the data wheel slide plates is equipped with an encoder bracket, and an encoder is mounted on the encoder bracket. The two ends of the material support roller main shaft are rotatably mounted on the material support roller slide plate via bearings.

[0008] The data wheel is mounted on the data wheel spindle via a key connection A. The two ends of the data wheel spindle are respectively provided with locking threads A, and locking nuts A are provided on the locking threads A. Multiple spacers A are provided between the locking nuts A and the data wheel, as well as between the two data wheels.

[0009] The inverted V-shaped material support roller is mounted on the main shaft of the material support roller via a key connection B. The main shaft of the material support roller is provided with locking threads B at both ends, and locking nuts B are provided on the locking threads B. Multiple spacers B are provided between the locking nuts B and the inverted V-shaped material support roller, as well as between the two inverted V-shaped material support rollers.

[0010] Spacer A and spacer B have the same structure, including two half spacers with a split design. The two half spacers are aligned and spliced ​​together by a concave-convex interlocking structure to form a complete spacer.

[0011] The present invention, by adopting the above-described structure, can bring the following beneficial effects: To achieve precise length measurement during the W-shaped steel strip conveying process, the production line features a specially designed measurement system that integrates a support roller assembly and a data wheel assembly. The support roller assembly provides stable support for the W-shaped steel strip, ensuring its flatness and preventing deviation during conveying, thus laying the foundation for subsequent measurements. The core component of the data wheel assembly is the data wheel, whose surface is treated with an anti-slip coating to ensure close contact with the surface of the W-shaped steel strip. The friction force generated during W-shaped steel strip conveying drives the data wheel to rotate synchronously, with the data wheel's rotational speed strictly matched to the W-shaped steel strip's conveying speed. The data wheel is rigidly connected to its main shaft, directly transmitting rotational power to the main shaft. The main shaft is seamlessly connected to the encoder via a high-precision coupling, precisely transmitting the mechanical rotational motion to the encoder. The encoder, as the core detection element, converts the rotational displacement into a standardized electrical signal, which is transmitted to the industrial controller in real time. The controller has a built-in dedicated data processing algorithm that performs filtering, counting, and conversion on the electrical signal to quickly derive the actual conveying length of the W-shaped steel strip. At the same time, the measurement results are output to the production line control system and display terminal in real time through the communication interface. Finally, the continuous and high-precision measurement of the steel strip length is completed by rolling counting, which meets the needs of real-time monitoring and data traceability of material length in the production process.

[0016] Furthermore, the terms “vertical,” “upper end,” “lower end,” “A,” “B,” etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0017] In this invention, unless otherwise explicitly specified and limited, the terms "provided with," "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] like Figure 1-5As shown, the automatic length measuring and counting device for a mining W-shaped steel strip production line includes a data wheel assembly 2 and a material support roller assembly 3, which are spaced apart from top to bottom on the production line frame 1. The W-shaped steel strip 4 passes between the data wheel assembly 2 and the material support roller assembly 3. The material support roller assembly 3 includes a rotatable material support roller main shaft 301, on which two inverted V-shaped material support rollers 302 are spaced apart. Here, the inverted V-shaped material support rollers 302 act on the inverted V-shaped grooves of the W-shaped steel strip 4. The data wheel... Component 2 includes a rotatable data wheel spindle 201, on which two data wheels 202 are spaced apart. The data wheels 202 press against the W-shaped steel belt 4 to ensure that the data wheels 202 are in contact with the W-shaped steel belt 4 and have a certain clamping force, thereby ensuring that the W-shaped steel belt 4 can drive the data wheels 202 to rotate synchronously through friction when it is conveyed in a straight line. One end of the data wheel spindle 201 is connected to the encoder 204 through a coupling 203, and the encoder 204 is connected to the controller 5. By designing a material support roller assembly 3 and a data wheel assembly 2 on the production line, the data wheel 202 in the data wheel assembly 2 presses against the W-shaped steel belt 4. When the W-shaped steel belt 4 is conveyed, it drives the data wheel 202 to rotate synchronously. The rotation of the data wheel 202 drives the data wheel spindle 201 to rotate, and the data wheel spindle 201 drives the encoder 204 to rotate through the coupling 203. The encoder 204 converts the rotational displacement into an electrical signal and sends it to the controller 5. The controller 5 processes the data to obtain the length measurement result and can output the measurement result in real time. This device uses a rolling counting method to realize the length measurement of the W-shaped steel belt 4. It has the advantages of accurate and reliable length measurement.

[0019] The production line frame 1 is vertically equipped with a slide groove 6, on which a data wheel slide plate 7 and a material support roller slide plate 8 are respectively mounted. A data wheel adjusting bolt 9 is located at the upper end of the slide groove 6, acting on the upper end of the data wheel slide plate 7. A material support roller adjusting bolt 10 is located at the lower end of the slide groove 6, acting on the lower end of the material support roller slide plate 8. A limiting block 11 is provided between the data wheel slide plate 7 and the material support roller slide plate 8. The two ends of the data wheel main shaft 201 are rotatably mounted on the data wheel slide plate 7 via bearings. One of the data wheel slide plates 7 is equipped with an encoder bracket 205, which houses an encoder 204. The two ends of the material support roller main shaft 301 are rotatably mounted on the material support roller slide plate 8 via bearings. By designing the data wheel slide plate 7 and the material support roller slide plate 8, vertical adjustment can be achieved, thereby meeting the length measurement requirements of W-shaped steel strips 4 of different heights. The limit block 11 can ensure that the spacing is within the set range, and prevent the data wheel 202 from exerting too much pressure on the W-shaped steel belt 4, which would affect normal conveying.

[0020] The data wheel 202 is mounted on the data wheel spindle 201 via a key connection A206. Both ends of the data wheel spindle 201 are provided with locking threads A207, and locking nuts A208 are provided on the locking threads A207. Multiple spacers A209 are provided between the locking nuts A208 and the data wheel 202, and between the two data wheels 202. The spacers A209 can be adjusted according to the width of the W-shaped steel strip 4.

[0021] The inverted V-shaped material support roller 302 is mounted on the material support roller main shaft 301 via a key connection B303. Both ends of the material support roller main shaft 301 are respectively provided with locking threads B304, and locking nuts B305 are provided on the locking threads B304. Multiple spacers B306 are provided between the locking nuts B305 and the inverted V-shaped material support roller 302, and between two inverted V-shaped material support rollers 302. Similar in structure to the data wheel assembly 2, the spacers B306 can be adjusted according to the width of the W-shaped steel strip 4.

[0022] Spacer A209 and spacer B306 adopt the same structure, including two separate half-spacer sleeves 12. The two half-spacer sleeves 12 are aligned and spliced ​​together by a tongue-and-groove interlocking structure 13 to form a complete spacer sleeve. The splicing surfaces fit tightly, and no additional tools are required for assembly and disassembly. The assembly state can be flexibly adjusted according to actual usage needs, balancing connection stability and ease of operation. Individual disassembly of the spacer sleeves is possible, facilitating later maintenance and adjustment; that is, width adjustment can be completed without disassembling other components. In practical applications, simply replace the spacer sleeve with one of different widths according to the required width.

[0023] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0024] Any aspects of this utility model not described in detail are known to those skilled in the art.
