Problems solved by technology

This method has its own shortcomings that are difficult to overcome: one, a vulcanizing machine can only correspond to one type of tire, and cannot meet the repair needs of the diversified development of multi-brand, multi-model, and multi-type tires, or it needs to invest a lot of equipment and equipment. Funds, or can only repair individual tires; 2. Use local vulcanizers to vulcanize and repair tires. Due to different tire types, tire arcs and machine models do not match, and the repairs often deform. The four corners of the reinforcing pad are due to the built-in The airbag does not fit well with the shape of the tire and the vulcanizer, resulting in insufficient pressure on the reinforcement pad and improper vulcanization. After the tire is used, the edge is easy to warp, the edge of the reinforcement pad is easy to explode, or the tire is easy to deform and other safety hazards.
[0005] Today, under the situation of soaring consumption indexes such as tire prices, repair raw materials, and labor costs, the conventional tire repair fees in most parts of the country do not rise but fall to the bottom line of cost. This phenomenon is in line with the booming development of the tire industry. Incongruous, out of line with the messiness of a tire patch
The root cause of this abnormal phenomenon is the poor quality of local vulcanizing machines repairing vulcanized tires.
Especially for the repair of vacuum tubeless tires that are suitable for high-speed transportation of vehicles. Because of its special structure, it has high requirements for repair and vulcanization technology. The current local vulcanizers are not suitable for its high requirements, and there is no such kind of fine technology repair. Airbags for local vulcanizers; and high-load extra-large engineering tires require the purchase of very heavy vulcanizers and the insertion of large and heavy airbags, so it is not realistic to use this equipment to repair and vulcanize such tires

Embodiment 1

[0036] Such as figure 1 As shown, the novel steam tire repairing device of the present invention includes a steam generator 1, an inner tube, a tire rim assembly 2 adapted to fit with the tire opening so that the tire can be stably pressure-bearing, and placed outside the tire and pressed against the wound. Point vulcanized heat transfer components. The steam generator 1 is a pot-shell type fully automatic electric water steam generator, including an air pipeline 11 connecting the tire inner tube to the steam generator and a fully automatic electric control system to automatically control the water level and pressure to ensure safe use.

[0037] Such as figure 2 , 3 As shown, the above-mentioned tire steel ring assembly 2 includes a first steel ring 21 and a second steel ring 22 that are interlocked with each other. The inner wall of the first steel ring 21 is provided with a stator 211, and the inner wall of the second steel ring 22 is provided with a buckle with the stato...

Embodiment 2

[0047] Such as Figure 5 , 6 As shown, the implementation of this embodiment is basically the same as that of Embodiment 1, except that the heat conduction component of this embodiment is a steam heat conduction capsule 5, which is fixedly connected to the outside of the tire by binding an elastic band 6, and includes a high temperature steam capsule that can be filled with high temperature steam. The sealed hollow capsule structure of the capsule structure adopts the soft glue layer that silicone rubber and canvas layer are made to sew to form, and its inner back 51 thickens line layer and is provided with air inlet nozzle 52 and drain valve 53 thereon. The steam heat-conducting capsule 5 has versatility, and can be applied to the tire crown, tire shoulder and sidewall, and can even be covered on the steel rim for vulcanization of the tire toe. The rest of the vulcanization repair methods and beneficial effects are basically the same as those of the above-mentioned embodimen...

Embodiment 3

[0049] Such as Figure 7 , 8 As shown, the implementation of this embodiment is basically the same as the above embodiment, the difference is that the heat conduction component of this embodiment is an aluminum mold electric heating element 7, which is provided with an aluminum mold shell 11, and a temperature control heating element is arranged inside the shell 11 . The aluminum mold electric heater 7 is also divided into crown aluminum mold electric heater, tire shoulder aluminum mold electric heater and sidewall aluminum mold electric heater according to the different vulcanization repair positions. During use, the aluminum mold electric heating element 7 is fixed on the external wound of the tire by the metal fixing frame 4, the temperature control electric heating element is energized and heated, and the aluminum film casing 11 transfers heat to the wound of the tire, thereby achieving the purpose of vulcanizing and repairing the external wound of the tire. The rest of ...

Abstract

The invention discloses a method for repairing tyres by steam and a device thereof; the method includes the following steps: a, filling unvulcanized rubber and bonding a reinforcing cushion outside the wound of a tyre; sheathing an inner tyre and a protective pad into the tyre and then compacting and closing the tyre opening so as to lead the tyre to be capable of bearing stably; b, filling steam with high temperature into the inner tyre and the steam with high temperature leads the inner tyre to expand and transfer the hot pressure of the steam to the reinforcing cushion and then to the whole tyre; c, after the tyre reaches setting pressure, compacting the wound at the outside of the tyre by a heat-conductive component and heating, pressurizing, vulcanizing and repairing the wound; d, stopping inputting the steam with high temperature and stopping heating the heat-conductive component after finishing the internal and the external vulcanizing and repairing on the wound. The invention takes the steam as a vulcanizing medium; the outside of the invention is additionally provided with a point type heat-conductive component; internal and external heating and pressurizing are carried out so as to vulcanize and repair the tyres with different shapes and varieties; any location needed repairing of the whole tyre can be vulcanized and repaired by one time; besides, a plurality of different tyres can be simultaneously vulcanized and repaired; the method of the invention can realize pipelining vulcanizing and repairing operations, which has high efficiency, high quality and low cost.

Description

technical field [0001] The invention relates to a method and device for vulcanizing and repairing tires, in particular to a method and device for vulcanizing and repairing tires of various types by steam vulcanization. Background technique [0002] With the continuous development of the social economy, the tire manufacturing industry has numerous varieties and types of tires to meet the needs of social transportation, logistics and engineering machinery construction; on the other hand, with the soaring international rubber prices, the price of tires is also low Festival skyrocketed. Regardless of whether it is a car, a large truck, or an engineering locomotive, tires will inevitably be damaged by debris during use and need to be repaired, so more and more people are engaged in the tire repair industry in the society. [0003] At present, the most commonly used tire repair method is "fire repair", that is, using a local vulcanizer corresponding to a certain type of tire of a...
