Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically to a device for preventing rubber fibers from falling into the inner cavity of a tire. Background Technology
[0002] Vulcanization is a crucial step in tire manufacturing, involving the tight bonding of rubber to the mold and the formation of the rubber's internal structure. During vulcanization, the rubber material expands under heating and pressure, generating gases that need to be released to prevent the formation of air bubbles or defects inside the tire.
[0003] To address this issue, engineers design vents in the mold to allow gases to escape smoothly during vulcanization. However, this design also results in numerous needle-like rubber fibers on the tire tread and sidewalls. While these fibers don't affect tire performance, they do impact its appearance. Therefore, to improve the tire's aesthetics, factories remove these fibers after vulcanization. Currently, most factories in China use manual removal with a trimmer. While simple, this method has several drawbacks: due to their light weight and large quantity, these fibers easily fall into the tire's internal cavity during removal. If not detected and removed promptly, they may be discovered during tire use, negatively impacting the company's brand image.
[0004] Therefore, it is necessary to develop a rubber lint removal device that can prevent rubber lint from falling into the tire cavity in order to solve the problems existing in the current lint removal methods. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device to prevent rubber hair from falling into the inner cavity of the tire. By using two discs to block the two sides of the tire bead opening, it can effectively prevent rubber hair from falling into the inner cavity of the tire during hair removal, reduce the secondary inspection process after tire hair removal, and avoid customer complaints and adverse effects.
[0006] The technical solution of this utility model is as follows:
[0007] A device for preventing rubber fibers from falling into the inner cavity of a tire includes two discs, each with a connector on one side. The two discs are placed on both sides of the tire bead and completely cover the tire bead before being fixed together by the connector.
[0008] Preferably, the connector is detachably mounted on the disk.
[0009] Preferably, the connector includes a telescopic arm detachably mounted on the disc, and an adsorption element is provided at the end of the telescopic arm, wherein the adsorption elements of the telescopic arms on the two discs are adsorbed and fixed together.
[0010] Preferably, the telescopic arm is a hydraulic cylinder, and the suction element is mounted on the piston rod of the hydraulic cylinder.
[0011] Preferably, the adsorption element is an electromagnetic chuck.
[0012] Preferably, the disk is provided with two connectors.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] 1. The device of this utility model uses two discs to cover the two sides of the tire bead opening, which can effectively prevent the rubber hair from falling into the tire cavity during the hair removal process, reduce the secondary inspection process after tire hair removal, and avoid customer complaints and adverse effects.
[0015] 2. The device of this utility model is designed to be detachably connected to the disc and the connector, and the connector is designed to be telescopic. The disc of the corresponding size can be adjusted according to the tire specifications, so as to ensure that it can completely cover the inner cavity of the tire and prevent the rubber sheet from falling into the inner cavity during hair removal. At the same time, the disc can be replaced separately when it is deformed or damaged, saving costs. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.
[0021] Example 1
[0022] like Figure 1-2As shown, this embodiment provides a device for preventing rubber fibers from falling into the inner cavity of a tire, including two discs 2. Connectors are respectively provided on one side of each disc 2. The two discs 2 are respectively placed on the tire bead 101 (e.g., ...). Figure 3 The two sides of the tire (as shown) are completely covered by the tire 1 circumference 101 and then fixed together by the connector.
[0023] In use, two discs 2 are placed on both sides of the bezel 101 of the tire 1, and then the two discs 2 are fixedly connected together by a connector. Then, the worker can begin to remove the rubber hair from the tire 1. After the hair removal is completed, the discs 2 on both sides are removed, and the next tire 1 can be processed. In this embodiment, by using two discs 2 to cover the bezel 101 on both sides of the tire 1, the rubber hair can be effectively prevented from falling into the inner cavity of the tire 1 during hair removal, reducing the need for secondary inspection after tire hair removal, and avoiding customer complaints and adverse effects.
[0024] Furthermore, the connector can be designed to be detachably mounted on the disc 2, such as through bolt connections. Since tire 1 has different specifications and different bead sizes 101, discs 2 of different sizes need to be replaced to accommodate different tire 1 specifications. During replacement, the connector can be removed and installed on the new disc 2; additionally, if the disc 2 is deformed or damaged, it can be replaced separately.
[0025] Similarly, after placing the disc 2 at the bead 101 of the tire 1, the distance between the two discs 2 will vary depending on the tire size 1. Therefore, in order to ensure that the two discs 2 can be smoothly and securely connected by the connector, such as... Figure 1 In this embodiment, the connector includes a telescopic arm 3 detachably mounted on the disc 2. An adsorption element is provided at the end of the telescopic arm 3, and the adsorption elements of the telescopic arms 3 on the two discs 2 are adsorbed and fixed together. The telescopic arm 3 can be a hydraulic cylinder, and the adsorption element can be an electromagnetic chuck 4 mounted on the piston rod of the hydraulic cylinder. When the tire 1 specification is input into the control system, the hydraulic cylinder automatically extends and retracts to bring the two opposing electromagnetic chucks 4 into contact. Then, the electromagnetic chucks 4 are energized to adsorb together, thus achieving a fixed connection between the two discs 2 and fixing the entire device at the tire 1 bead 101. Using electromagnetic chucks 4 to adsorb the two discs 2 makes the entire device stable and eliminates the need for manual support, resulting in high working efficiency.
