Description

Technical Field

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

[0002] In the rubber industry, a double-drum vulcanization continuous preparation device is often used to vulcanize rubber. The device consists of two side-by-side drum wheels, usually made of high-temperature heated metal, which can evenly heat the rubber. The rubber is fed between the two drums by continuous feeding. During the rotation, it contacts the drum surface and is subjected to high temperature and pressure, so that the rubber undergoes a vulcanization reaction in a constantly changing environment, thereby improving the elasticity and strength of the rubber.

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

[0004] 1. Only vertical pressure may not provide sufficient pressing force in the lateral or side direction of the rubber, which may lead to insufficient density and uniformity of the rubber. For thicker rubber products, the vertical pressure may be difficult to be fully transmitted to the inside, resulting in uneven cross-linking reaction inside the rubber during vulcanization. In addition, the rubber may have insufficient cross-linking reaction in some local areas due to insufficient pressure, thus affecting the performance after vulcanization.

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

[0006] 3. During the vulcanization process of rubber, if there is only vertical pressure, the rubber surface may be pressed tightly, while the inside may form pores or uneven layers due to the lack of effective lateral pressure. The thickness of the rubber after vulcanization may be inconsistent 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 of the invention

[0019] S2. Then, the first power supply cabin and the second power supply cabin are started to supply power to the first electric heating pipe and the second electric heating pipe respectively. The first electric heating pipe generates heat and transfers the heat to the lower vulcanization drum through the first steel pipe, thereby increasing the surface temperature of the lower vulcanization drum.

The linkage disk links the adjustment disk to approach the swing disk and deviates the swing disk under the push of the connecting rod. Then the shaft motor is started to drive the shaft and the swing disk to rotate. The steel ball slides along the outer slide groove after the swing disk is deviated and drives the reciprocating slide rod to slide back and forth on the U-shaped support, thereby driving the upper rotating frame and the upper vulcanization drum to continuously shake back and forth in the horizontal direction.
