Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber vulcanization, in particular to a double-drum vulcanization continuous preparation device and process. BACKGROUND

[0002] In the rubber industry, a double-drum vulcanization continuous preparation device is often used to vulcanize rubber. The device is composed of two parallel drums, usually made of high-temperature heated metal, which can uniformly heat the rubber. The rubber is fed between the two drums in a continuous manner, and in the process of rotation, it is in contact with the drum surface and is subjected to high temperature and pressure, so that the rubber undergoes vulcanization reaction in a changing environment, thereby improving the elasticity and strength of the rubber.

[0003] In the traditional double-drum vulcanization device, the pressure applied to the rubber is mainly achieved through physical contact between the two heated drums and a pressure adjustment system. The pressure applied is mainly perpendicular to the surface of the heated drum, that is, the pressure on the rubber is along the normal direction of the surface of the heated drum, that is, from top to bottom or from bottom to top. However, applying pressure only perpendicular to the surface of the heated drum may have some impact on the vulcanization of the rubber:

[0004] 1. Only vertical pressure may not provide sufficient pressing force in the lateral direction of the rubber, which may result in insufficient density and uniformity of the rubber. For thicker rubber products, vertical pressure may not be able to fully transmit to the inside, resulting in uneven crosslinking reaction in the interior of the rubber during the vulcanization process, and the rubber in the local area may not be fully crosslinked due to insufficient pressure, thereby affecting the performance after vulcanization;

[0005] 2. During the vulcanization process, not only pressure but also uniform heating is required. The application of vertical pressure may cause the rubber to be pressed along the surface of the heated drum, while heating may also cause the shape of the rubber to be affected by thermal expansion or contraction. If only vertical pressure is relied on, it may affect the uniform heating and pressure distribution of the rubber, thereby affecting the vulcanization effect and product quality;

[0006] 3. If only vertical pressure is applied during the vulcanization process of the rubber, the surface of the rubber may be tightly pressed, while the interior may form pores or uneven layers due to the lack of effective lateral pressure. The thickness of the vulcanized rubber may not be consistent due to the difference in surface and internal pressure.

[0007] Therefore, it is necessary to invent a double-drum vulcanization continuous preparation device and process. SUMMARY

DETAILED DESCRIPTION

[0039] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0040] Example 1, such as Figure 1 - Figure 7 As shown, a dual-drum vulcanization continuous preparation device according to a first aspect embodiment of the present invention includes a gantry frame 11, conveying components arranged on both sides of the gantry frame 11, and a lower pressure plate 19, an upper rotating frame 30, and a lower rotating frame 20 arranged sequentially from top to bottom on the inner side of the gantry frame 11. Sliding angle steels 18 are fixedly installed at both ends of the lower pressure plate 19. The sliding angle steels 18 are vertically slidably installed on the upper part of the inner side of the gantry frame 11. Multiple hydraulic push rods 17 are connected to the top and bottom surfaces of the sliding angle steels 18, and the hydraulic push rods 17 are embedded in the gantry frame. A horizontal shaking assembly is installed between the lower pressure plate 19 and the upper rotating frame 30. The horizontal shaking assembly is used to drive the upper rotating frame 30 to shake horizontally. An upper hot pressing assembly is installed below the upper rotating frame 30. The upper hot pressing assembly includes an upper vulcanizing drum 35. The lower rotating frame 20 is fixedly installed on the ground directly below the gantry frame 11. A lower hot pressing assembly is installed on the top surface of the lower rotating frame 20. The lower hot pressing assembly includes a lower vulcanizing drum 25. The surfaces of the upper vulcanizing drum 35 and the lower vulcanizing drum 25 are provided with strip-shaped protrusions that can interlock with each other.

[0041] In the above embodiments, it should be noted that both the upper vulcanizing drum 35 and the lower vulcanizing drum 25 are made of heat-resistant and pressure-resistant metal materials. The hydraulic push rod 17 is externally connected to the control system and power supply. The first motor 14 and the second motor 16 pass through the conveying assembly, the upper vulcanizing drum 35 and the lower vulcanizing drum 25. The conveying assembly is started to continuously transmit rubber. By starting the upper hot pressing assembly and the lower hot pressing assembly, the surface temperature of the upper vulcanizing drum 35 and the lower vulcanizing drum 25 is heated to 140°C to 180°C. The horizontal shaking assembly drives the upper rotating frame 30 to drive the upper vulcanizing drum 35 to shake horizontally. Then, the hydraulic push rod 17 is started to drive the sliding angle steel 18 to drive the lower pressure plate. 19 and the upper rotating frame 30 move downwards, pushing the upper vulcanizing drum 35 downwards and continuously squeezing the surface of the rubber raw material with the lower vulcanizing drum 25. The strip-shaped protrusions on the surfaces of the upper vulcanizing drum 35 and the lower vulcanizing drum 25 apply pressure to the surface of the rubber raw material in multiple directions. This achieves the effect of increasing the lateral or side pressure on the rubber in addition to applying pressure in the vertical direction, and fully and evenly transmits the pressure to the inside of the rubber. This is conducive to uniform heating and pressure distribution inside the rubber, making the cross-linking reaction inside the rubber more uniform during vulcanization, improving the performance of the rubber after vulcanization. It can also effectively avoid the formation of pores or uneven layers inside the rubber caused by unidirectional pressure.
