Description

Technical Field

[0001] The utility model belongs to the technical field of vulcanizing machines, in particular to a vulcanizing machine with good temperature measurement effect. Background Art

[0002] A hot plate vulcanizer is a type of equipment commonly used in rubber processing. It primarily uses heat from a hot plate and pressure from a hydraulic system to vulcanize the rubber in a mold. The basic principle is to place the rubber raw material in a mold, transfer heat through the hot plate, and raise the temperature to the required vulcanization range. Simultaneously, a certain pressure is applied to induce cross-linking of the rubber molecular chains, forming a vulcanized rubber with excellent properties. A hot plate vulcanizer generally consists of a heating plate, a hydraulic system, a control system, and a mold. Precise control of temperature, pressure, and time ensures a stable and efficient vulcanization process. The equipment's temperature and pressure can be adjusted to suit different rubber materials and product requirements, making it highly adaptable and widely used in the production of rubber products such as tires, seals, and automotive gaskets. Its ease of operation and high production efficiency make it a common and important piece of equipment in rubber product manufacturing.

[0003] After long-term use, the temperature measuring holes of existing vulcanizers will become stuck and blocked, which prevents the gas in the vulcanization chamber from entering the holes, resulting in inaccurate temperature measurement by the thermocouple. Utility Model Content

[0015] The present invention is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention. The methods used in the present invention are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0016] In this embodiment, a hot plate type vulcanizing press produced by Yiyang Yishen Rubber Machinery Co., Ltd. is used for description.

[0017] like Figure 1 As shown in Figure 3, the present invention provides a vulcanizer with excellent temperature measurement effect, including a vulcanizing platform 2. A base 7 is provided at the bottom of the vulcanizing platform 2. A space is defined within the base 7. A first telescopic rod 8 is disposed within the space. A positioning seat 10 is fixedly connected to the first telescopic rod 8. The positioning seat 10 is in the shape of an I-shaped wheel, and the diameter of the I-shaped wheel is adapted to the inner diameter of the tire blank to be vulcanized. A capsule 9 is also provided on the positioning seat 10. A wall 6 is fixed around the positioning seat 10, which is higher than the vulcanizing platform 2. The diameter of the wall 6 is adapted to the outer diameter of the tire blank to be vulcanized.

[0018] like Figure 2 As shown, vertical plates 1 are provided on both sides of the vulcanization platform 2. A rotating shaft 3 is rotatably connected between the vertical plates 1. A flip plate 4 is fixedly connected to the rotating shaft 3. A second telescopic rod 12 that runs synchronously is fixedly connected to the flip plate 4. A gland 5 is fixedly connected to the second telescopic rod 12. The gland 5 has the same size as the wall 6. When the gland 5 and the wall 6 are buckled together, a vulcanization cavity is formed. Figure 4As shown, a temperature measuring hole 11 is also defined in the top wall of the gland 5. This hole 11 is trumpet-shaped, near one end of the vulcanization chamber, with its diameter gradually increasing from the outer to the inner top wall of the gland 5. During temperature measurement, a thermocouple 13 is inserted into the hole, with the probe at the bottom of the thermocouple 13 elevated above the plane of the inner top wall of the gland 5. This trumpet-shaped hole increases the space available for gas within the vulcanization chamber to enter the hole, ensuring accurate gas temperature measurements. It also prevents impurities generated during the vulcanization of the tire from clogging the hole 11.

[0019] When the vulcanizer is in use, the tire to be vulcanized is placed inside the enclosure 6, with the center of the tire aligning with the center of the positioning seat 10. The first telescopic rod 8 is then extended, and after the positioning seat 10 passes through the middle of the tire, the bladder 9 is inflated until it fills the inner cavity of the tire, positioning the tire. The rotating shaft 3 then rotates the flip plate 4, moving the gland 5 directly above the tire. The second telescopic rod 12 is extended, driving the gland 5 downward until it engages with the enclosure 6, and vulcanization of the tire begins.

[0020] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] However, the above description is merely a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
