Description

Technical Field

[0001] This utility model relates to the technical field of tire cord fabric production and processing equipment, specifically a tire cord fabric adhesion detection device. Background Technology

[0002] The tire's carcass layer forms its skeleton, providing exceptional strength to the entire tire. It's a fabric layer composed of parallel rubber-coated cords, meticulously woven together to provide the tire with the necessary strength and stability. These cords act like the tire's "muscles," giving the tire carcass and the entire outer tire the necessary strength. Steel cord calendering is primarily used for the carcass carcass and belt layers of all-steel radial tires, as well as the belt layer carcass of semi-steel radial tires. The calendering quality of the steel cord has a significant impact on the performance of radial tires. The manufacturing methods for steel cord mainly include hot calendering and cold calendering, with hot calendering being the most common method.

[0003] Existing devices mainly test the tackiness of tire cord rubber, but the tackiness of the rubber is different from that of the tire cord layer. The rubber and the tire cord are formed into the tire cord layer through calendering. Different calendering processes result in different surface tackiness of the tire cord layer. Therefore, a device for testing the tackiness of tire calendered tire cord is needed.

[0004] Based on this, a tire cord adhesion testing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, a tire cord adhesion testing device includes a base 1, a pair of supports 2 connected to one side of the base 1, a rangefinder 7 disposed on the side of the supports 2 away from the base 1, a test platform 4 disposed at the bottom of the supports 2, an acceleration section 8 disposed at the end of the base 1 near the supports 2, a steel ball storage box 12 disposed at the top of the base 1, a plurality of test steel balls 10 placed inside the steel ball storage box 12, a discharge assembly disposed inside the steel ball storage box 12, a drop outlet 22 opened on the side of the steel ball storage box 12 near the acceleration section 8, an insertion channel 14 disposed at the top of the steel ball storage box 12 away from the drop outlet 22, and an insertion groove 11 connected to the top of the insertion channel 14;

[0025] In this embodiment, the staff places the calendered cord fabric to be tested on the test table 4 and controls the discharge component to release the test steel ball 10. The test steel ball 10 first passes through the acceleration section 8 to form a certain impact force and then rolls on the calendered cord fabric. The rangefinder 7 can measure and display the rolling distance of the test steel ball 10 to determine whether the surface viscosity of the cord fabric is qualified, thereby inspecting the surface of the calendered cord fabric layer.

[0026] In one embodiment, such as Figure 2 and Figure 3 As shown, the discharge assembly includes an inclined plate 15. An adsorption assembly is provided on the upper surface of the inclined plate 15 near the drop outlet 22. A limiting assembly is provided behind the adsorption assembly. The inclination of the inclined plate 15 is relatively gentle, which allows the test steel ball 10 to automatically roll towards the drop outlet 22 without generating a large impact force. The test steel ball 10 closest to the drop outlet 22 will be adsorbed by the adsorption device and stop rolling.

[0027] In one embodiment, such as Figure 3As shown, the adsorption assembly consists of an electromagnet 19 that is powered on. The test steel ball 10 is magnetically adsorbed by the electromagnet 19. When the electromagnet 19 is powered on, it generates an adsorption force on the test steel ball 10. When the power is turned off, it loses its magnetism and the test steel ball 10 will continue to roll.

[0028] In one embodiment, such as Figure 3 and Figure 4 As shown, the limiting component includes a slot 21 opened on one side of the steel ball storage box 12. A plate 16 is slidably connected in the slot 21. An electric telescopic rod 17 is connected to the end of the plate 16 away from the steel ball storage box 12. The electric telescopic rod 17 is fixed to the base 1 by the second fixing component 18. When the electromagnet 19 is energized, the first test steel ball 10 is attracted and stationary, and the second test steel ball 10 slides down to be close to the first one. In order to prevent all steel balls from sliding down after the power is cut off, the electric telescopic rod 17 is first controlled to push out the plate 16 to separate the two test steel balls 10 before the power is cut off.

[0029] In one embodiment, such as Figure 3 As shown, a buffer pad 20 is provided on the upper surface of the inclined plate 15 near the insertion channel 14 to avoid the test steel ball 10 being directly inserted and generating a large impact force.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, a first fixing component 6 is provided on the top of the support 2. The side of the first fixing component 6 near the test table 4 is connected to a coding component 13. When a defective curtain is detected, the coding component 13 can be controlled to quickly mark it for easy identification later.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, a positioning bucket 9 is provided at the top of the acceleration section 8. The positioning bucket 9 has an opening at the rolling outlet 22. The positioning bucket 9 can ensure that the test steel ball 10 falls in the same position in the acceleration section 8 each time, reducing uncontrollable factors in the detection process.

[0032] In one embodiment, such as Figure 1 As shown, the bottom of the support 2 is provided with a conveying groove 5, and a pair of conveying devices 3 are provided on both sides of the test platform 4. The height of the conveying groove 5 is less than the diameter of the test steel ball 10. The curtain can be laid flat on the conveying device 3 and transported to the test platform 4 for testing. After the test is completed, the staff drags it to the other side of the conveying device 3 and transports it away.

[0033] The above embodiment discloses a tire cord adhesion testing device. In this device, a test steel ball 10 is placed into a steel ball storage box 12 through an insertion groove 11. When an electromagnet 19 is energized, the first test steel ball 10 is attracted and remains stationary. The calendered cord is conveyed to the test table 4 by a conveying device 3 on one side. To prevent all the steel balls from slipping after the electromagnet 19 is de-energized, the electric telescopic rod 17 is first controlled to push out the insertion plate 16 to separate the test steel balls 10. Then the power is turned off. The test steel ball 10 passes through the positioning bucket 9 and first passes through the acceleration section 8 to form a certain impact force before rolling on the calendered cord. The rangefinder 7 can measure and display the rolling distance of the test steel ball 10 to determine whether the surface viscosity of the cord is qualified. When unqualified cord is detected, the marking component 13 can be controlled to quickly mark it for easy identification later. This allows for the detection of the surface of the calendered cord layer. After the test is completed, the operator drags it to the other side conveying device 3 for transport.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
