Description

Technical Field

[0001] The utility model relates to the technical field of water leakage detection of a central mechanism of a vulcanizing machine, in particular to a water leakage detection and alarm device of a central mechanism of a vulcanizing machine. Background Art

[0002] The vulcanization production process of tires is as follows: ① The tire blank is placed on the central mechanism of the vulcanizer through a robot; ② The upper ring descends, and the capsule is shaped to expand the tire blank into place; ③ The mold is closed in place and the vulcanization process medium is introduced. The mold is opened after a certain pressure, time, and temperature. When the seal of the central mechanism is worn, it is very easy to leak. If water flows into the capsule, the vulcanization temperature of the tire is reduced during the vulcanization process, resulting in poor tire vulcanization. Some unqualified tires cannot be detected by appearance. If they enter the market, there will be serious safety hazards. In addition, since there are multiple sealing surfaces on the central mechanism, it is difficult to find the leakage point. Generally, all seals are replaced as a whole, which leads to high maintenance costs. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0021] Combined with Figure 1-5 It can be known that the device includes a central mechanism body 1, and a water inlet pipe 2 and a water outlet pipe 3 are arranged on both sides of the central mechanism body 1. A leak detection device is vertically arranged on one side of the water inlet pipe 2, and pressure detection mechanisms are arranged at the water inlet pipe 2 and the water outlet pipe 3. The two pressure detection mechanisms are fixed to the outside of the central mechanism body 1 through a fixing ring 4.

[0022] The leak detection device comprises an infusion tube 5 fixed on one side of the water inlet pipe 2, the infusion tube 5 is filled with fluorescent pigment, a through hole 5.2 connected to the water inlet pipe 2 is provided on the top of one side of the infusion tube 5, so as to facilitate the injection of the fluorescent pigment into the water inlet pipe 2, the infusion tube 5 is internally divided into an injection chamber 5.1 and a one-way valve chamber 5.3, a circular hole 5.4 is provided between the injection chamber 5.1 and the one-way valve chamber 5.3, a valve ball 6 is placed in the one-way valve chamber 5.3, and an opening 5.5 is provided on one side of the injection chamber 5.1; the diameter of the valve ball 6 is larger than the diameter of the circular hole 5.4, so as to prevent the water in the water inlet pipe 2 from flowing back into the one-way valve chamber 5.3, and play the role of a one-way valve, and the lower side of the one-way valve chamber 5.3 and the upper side of the injection chamber 5.1 are connected. All of them are conical surfaces; the pressure detection mechanism includes a pressure sensor 7 and a transmitter 8, which are used to detect the pressure changes in the central mechanism body 1, so that it is convenient to send data to an external computer through the transmitter 8 to facilitate warning. The pressure sensor 7 is connected and arranged at the water inlet pipe 2 and the water outlet pipe 3. The fixing ring 4 is fixed to the outside of the central mechanism body 1 by bolts. Two extension rods 4.1 are opened on the side of the fixing ring 4, and the transmitter 8 is fixed at one end of the extension rod 4.1; the transmitter 8 is electrically connected to the external computer; the opening 5.5 is threaded and sealed with a sealing cover 9, and an electric push rod 10 is slidably arranged in the injection chamber 5.1, and a piston is fixed on the top of the electric push rod 10.

[0023] The working principle of the present application is as follows: when conducting water leakage detection, firstly, the fixing ring 4 is fixed to the outside of the central mechanism body 1 by bolts, and then the pressure sensor 7 is connected with the water inlet pipe 2 and the water outlet pipe 3, and then the data transmitted by the transmitter 8 is used to observe the pressure change in the central mechanism body 1. When the pressure changes, the external computer will sound an alarm, and then the fluorescent pigment is transported into the injection chamber 5.1 through the opening 5.5, and then the opening 5.5 is sealed by the sealing cover 9, and then under the push of the electric push rod 10, the fluorescent pigment is injected into the water inlet pipe 2 through the circular hole 5.4, the one-way valve chamber 5.3, and the through hole 5.2. During injection, the fluorescent pigment will push the valve ball 6 upward to facilitate the circulation of the fluorescent pigment. When the injection is completed, the valve ball 6 will block the circular hole 5.4 under the action of gravity, and play a one-way circulation effect. When the fluorescent pigment is injected into the water inlet pipe 2, it can pass through the inside of the central mechanism body 1, so the leaking place will have color, so as to quickly find the leaking place.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
