Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, specifically to an online sampling device for steel cord. Background Technology

[0002] Radial tires are increasingly widely used due to their advantages, leading to a year-on-year increase in demand for their main component, steel cord. Before leaving the factory, steel cord needs to undergo physical property testing. During the manufacturing stage, samples of steel cord are taken for testing various parameters and performance characteristics, such as diameter, linear density, coating, and elongation. These samples are called sampling discs, and one disc is retained for each batch of production. Steel cord discs are primarily used for product performance testing and customer shipments, meeting customer warehousing inspection requirements. They must be free of surface defects such as oil stains, rust, and bending deformation.

[0003] The conventional steel cord sampling operation involves stopping the production line after the I-beam reel is full, restarting the equipment to take another 30 meters of sample, and then manually winding the required sample onto the sampling reel to form a sample. However, this operation requires highly skilled workers and a strong sense of responsibility. Non-standard sampling operations may result in insufficient sample length, affecting product performance testing or delivery. Furthermore, excessively long sample lengths may lead to finished cord reels that are shorter than the customer's required length, causing customers to roll shorter lengths and resulting in waste. In addition, manual winding and sampling increases the labor intensity of workers and carries the risk of contaminating or bending the cord. Utility Model Content

[0004] The purpose of this invention is to provide an online sampling device for steel cord, which makes full use of the existing winding platform to achieve online sampling, eliminates the manual back-drawing operation, reduces the labor intensity of workers, and eliminates the risk of contaminating the sample cord due to manual winding.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an online sampling device for steel cord, comprising a platform, on which a driving assembly and a pin assembly are symmetrically arranged. The driving assembly includes a driving shaft, on which a first clamping plate is coaxially arranged. The pin assembly includes a pin coaxially arranged with the driving shaft, on which a second clamping plate is coaxially arranged. A bobbin wheel is arranged between the first clamping plate and the second clamping plate. A sampling disc is coaxially arranged between the second clamping plate and the bobbin wheel. The diameter of the end plate of the sampling disc is larger than the diameter of the end plate of the bobbin wheel. The edge of the end plate of the sampling disc is provided with a wire passage.

[0006] A further improvement of this utility model is that the sampling disc includes a cylindrical body and end plates located at both ends of the cylindrical body. The diameter of the central hole of the cylindrical body of the sampling disc is the same as the diameter of the central hole of the cylindrical body of the I-beam wheel. The ejector pin passes through the central hole of the cylindrical body of the sampling disc and is inserted into the central hole of the cylindrical body of the I-beam wheel.

[0007] A further improvement of this utility model is that the sampling disc includes an outer cylinder and an inner cylinder, a fixing ring is provided between the outer cylinder and the inner cylinder, and the diameter of the central hole of the inner cylinder is the same as the diameter of the central hole of the I-beam wheel.

[0008] A further improvement of this utility model is that the fixing ring has several reinforcing ribs on both sides, and the sampling plate has a circular opening coaxially on its end plate, the diameter of which is the same as the inner diameter of the outer cylinder.

[0009] A further improvement of this utility model is that one end of the reinforcing rib is connected to the outer wall of the inner cylinder, and the other end is connected to the inner wall of the outer cylinder.

[0010] A further improvement of this invention is that several reinforcing ribs are arranged in a row along the circumference of the center of the fixing ring.

[0011] A further improvement of this utility model is that the end plate of the sampling disk is provided with a number of insertion holes for fixing wire ends at intervals.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention fully utilizes the existing structure of the existing winding platform, which uses the drive assembly and ejector assembly to clamp the I-beam wheel and drive it to rotate to wind up the steel cord. By setting a sampling disc between the ejector assembly and the I-beam wheel, the sampling disc can rotate with the I-beam wheel to achieve online sampling, eliminating the need for manual back-pulling operation, reducing the labor intensity of workers, and eliminating the risk of contaminating the sample cord due to manual cord laying.

[0014] In this invention, the diameter of the end plate of the sampling tray is larger than the diameter of the end plate of the I-beam, and the edge of the end plate of the sampling tray is provided with a wire passage. After the tray is full, the cord is moved from the finished I-beam through the wire passage on the edge of the sampling tray end plate to the cylinder of the sampling tray. Then, the drive assembly is restarted to start winding. At this time, the wound steel cord is all wound around the cylinder of the sampling tray, realizing online sampling. After the sampling length set by the system is reached, the platform automatically stops. The worker only needs to melt the cord and remove the I-beam and the sampling tray to end the sampling.

[0015] The sampling tray of this utility model includes an outer cylinder and an inner cylinder, with a fixing ring between the outer cylinder and the inner cylinder. Several reinforcing ribs are provided on both sides of the fixing ring, which can improve the structural strength of the sampling tray. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0022] Combination Figures 1-4 It is known that an online sampling device for steel cord includes a base plate 1. A drive assembly 2 and a pin assembly 3 are symmetrically arranged on the base plate 1. The drive assembly 2 includes a drive shaft 4, on which a first clamping plate 5 is coaxially arranged. The pin assembly 3 includes a pin 6 coaxially arranged with the drive shaft 4, on which a second clamping plate 7 is coaxially arranged. A I-beam wheel 8 is arranged between the first clamping plate 5 and the second clamping plate 7. A sampling disk 9 is coaxially arranged between the second clamping plate 7 and the I-beam wheel 8. The diameter of the end plate 10 of the sampling disk 9 is larger than the diameter of the end plate of the I-beam wheel 8. The edge of the end plate 10 of the sampling disk 9 has a wire passage opening 11. The pin 6 can rotate with the I-beam wheel 8.

[0023] The sampling plate 9 is a sampling plate used for sampling steel cord. The sampling plate 9 includes a cylinder and end plates 10 located at both ends of the cylinder. The diameter of the central hole of the cylinder of the sampling plate 9 is the same as the diameter of the central hole of the cylinder of the I-beam wheel 8. The pin 6 passes through the central hole of the cylinder of the sampling plate 9 and is inserted into the central hole of the cylinder of the I-beam wheel 8.

[0024] The sampling disc 9 has an outer cylinder 12 and an inner cylinder 13. A fixing ring 14 is provided between the outer cylinder 12 and the inner cylinder 13. The diameter of the central hole of the inner cylinder 13 is the same as the diameter of the central hole of the I-beam wheel 8.

[0025] The fixing ring 14 has several reinforcing ribs 15 on both sides. The end plate 10 of the sampling disk 9 has a coaxial circular opening 16, the diameter of which is the same as the inner diameter of the outer cylinder 12. One end of the reinforcing rib 15 is connected to the outer wall of the inner cylinder 13, and the other end is connected to the inner wall of the outer cylinder 12. The several reinforcing ribs 15 are arranged in a circle around the center of the fixing ring 14.

[0026] The end plate 10 of the sampling tray 9 is provided with several insertion holes 17 at intervals for fixing the wire ends. After the sampling tray finishes winding the sample cord, the cord is melted and one end of the cord on the sampling tray 9 can be inserted into the insertion hole 17 for fixing, so as to prevent the wound steel cord on the sampling tray 9 from becoming loose.

[0027] Existing I-beam wheels have protrusions on the opposite sides of their end plates, and corresponding clamping plates have flower discs that mate with the protrusions. These flower discs have multiple grooves that mate with the protrusions, as seen in patent number CN201911355567.X, patent title: "An Improved Tooling for a Pin Flower Disc," where the flower discs and protrusions work together to ensure the stability of the I-beam wheel and drive shaft during synchronous rotation. In contrast, the reinforcing rib 15 of this invention not only mates with the grooves to ensure synchronous rotation but also sits on the side of the protrusion on the I-beam wheel. Even if the I-beam wheel slips during rotation, the reinforcing rib limits its movement, allowing it to continue rotating synchronously.

[0028] The working principle of the online steel cord sampling device provided by the utility model is as follows: When the steel cord is wound up, the sampling disc 9 and the I-beam wheel 8 are first installed together between the pin assembly 3 and the drive assembly 2. The sampling disc 9 and the I-beam wheel 8 are clamped between the first clamping plate 5 and the second clamping plate 7. The I-beam wheel 8 can be wound up normally. When the I-beam wheel 8 is fully wound up, the drive assembly 2 is stopped and the sampling operation is performed. The cord is moved from the I-beam wheel 8 through the wire passage 11 on the edge of the end plate 10 of the sampling disc 9 to the cylinder of the sampling disc 9. Then the drive assembly 2 is restarted to start winding. At this time, the wound steel cord is all wound around the cylinder of the sampling disc 9 to achieve online sampling. After the sampling length set by the system is reached, the drive assembly 3 stops. The worker only needs to melt the cord and remove the I-beam wheel 8 and the sampling disc 9 to end the sampling.
