Description

Compound high elasticity intelligence accuse temperature rubber roll

Technical Field

The application relates to the field of rubber rollers, in particular to a composite high-elasticity intelligent temperature control rubber roller.

Background

In the current industrial background, the composite high-elasticity constant temperature rubber roller has become a key component in the field of precision manufacturing, and plays a vital role in the high-precision manufacturing industries such as film preparation, treatment or assembly. These rubber rollers combine high elastic materials and temperature control technology to meet specific industrial manufacturing and processing requirements, provide uniform and accurate pressure and temperature transfer, and ensure product quality and processing efficiency.

However, the prior art has certain limitations in terms of temperature fluctuation and temperature uniformity, particularly for large size rubber rolls. During long runs, especially under continuous high speed operating conditions, conventional temperature control systems inside the rubber roll may not respond quickly to external temperature changes, resulting in temperature fluctuations. This is particularly true in the production of new films or highly sensitive materials where the need for temperature control is more stringent.

In addition, the current rubber roller can only realize one constant temperature and slow speed temperature change, but in certain special use situations, such as the production process of novel battery diaphragms, ultrathin coating films, high-performance composite materials and the like, the rubber roller not only needs to provide excellent elasticity so as to ensure uniform pressure transmission in the processing process, but also needs to realize rapid temperature change. This rapid temperature regulation capability is particularly important because the processing or curing process of some new materials requires that the rubber roll be rapidly cooled from high temperatures to a certain constant value when contacting the material to ensure the performance and structural stability of the material.

More specifically, for example, in the manufacture of certain specialized films or coatings, it may be necessary to initially process at high temperatures to achieve specific properties of the material, followed by rapid cooling to "lock" the material structure or chemical properties. This rapid temperature regulation is not only critical to maintaining the properties of the material, but is also important to improving production efficiency and reducing energy consumption.

In summary, the composite high-elasticity constant temperature rubber roller has important significance and value.

Fig. 1-4 illustrate an exemplary configuration of the present application, and as shown, specifically disclose a composite high elasticity intelligent temperature control rubber roll designed to provide precise temperature control and high elasticity to accommodate modern industrial process requirements. The following is a detailed structural description of the glue roller and a specific description of each structural layer.

Specifically, in terms of structural composition, in the embodiment, the rubber roller comprises a mandrel 1, a metal sleeve 2 sleeved outside the mandrel 1 and concentric with the mandrel 1, and an elastic layer 3 sleeved outside the metal sleeve 2 and concentric with the mandrel 1, wherein the mandrel is a core supporting structure of the composite high-elasticity intelligent temperature control rubber roller, and the mandrel 1 is made of high-strength alloy steel. The material not only provides enough mechanical strength to withstand various stresses during long-term operation, but also has good heat resistance, ensuring stability and durability under high-temperature or low-temperature conditions. In addition, the alloy steel is selected by considering good processing performance and welding performance, so that the mandrel is convenient to manufacture and subsequent assembly work.

In the present exemplary embodiment, the mandrel 1 is of hollow design, the central part forming a first flow channel 4 in the axial direction. The design not only reduces the overall weight of the rubber roller, but also provides a flow channel for circulating liquid heat exchange medium, and is a key part of a basic temperature control system. The diameter and length of the first flow channel 4 are carefully designed according to the specifications and temperature control requirements of the rubber roller to ensure that the liquid heat exchange medium can circulate effectively, and to achieve a fast and uniform heat transfer. In order to improve the thermal efficiency and prevent excessive heat transfer to the mandrel 1, and further to cause adverse effects such as overheat expansion of the mandrel 1, the outer wall surface and the inner wall surface of the mandrel 1 are both coated with a heat-insulating coating. The coating is made of high-temperature-resistant high-reflectivity materials, can effectively reduce heat radiation and heat loss, and simultaneously protects the mandrel 1 from corrosion and chemical attack.

In this embodiment, the mandrel 1 and the metal sleeve 2 are connected and matched by a plurality of connecting rods 5, the connecting rods 5 are uniformly distributed around the mandrel 1, not only the position of the metal sleeve 2 is fixed, but also the necessary gap between the two is maintained, a first annular interlayer is formed, two ends of the annular interlayer are sealed by end covers, the first annular interlayer is used as a flow path of the liquid heat exchange medium, an annular second flow channel 6 for exchanging the liquid heat exchange medium is formed, and the second flow channel 6 is communicated with one end of the first flow channel 4 and is communicated and matched with an external liquid feeding device, and is used as a flow channel of the liquid heat exchange medium for basic temperature control.

It should be understood that the connecting rod 5 is made of a material with a low thermal conductivity, and its design considers the structural stability and the effect of thermal expansion, ensuring the overall stability of the rubber roller structure at the time of temperature change.

In this embodiment, the metal sleeve 2 is mainly used as a flow passage for a heat transfer medium and provides a firm supporting structure for the soaking layer 7 and the elastic layer 3, and it is understood that the metal sleeve 2 is usually made of a metal material with good heat conductivity, such as a copper alloy or an aluminum alloy, and the metal material has high heat conductivity and can quickly and uniformly transfer heat, so that the uniform heat distribution on the surface of the rubber roller is realized and the quality of the processed material is improved through the high heat conductivity.

It will be appreciated that copper alloys are widely used for their excellent heat transfer properties, while aluminum alloys are favored for their lighter weight and good corrosion resistance. The materials are selected with consideration of compatibility with other components, durability and processability. The metal sleeve 2 is coaxially concentric with the mandrel 1 and is sleeved outside the mandrel 1. The design ensures the overall symmetry and balance of the rubber roller. It should be appreciated that in order to increase the mechanical strength and corrosion resistance of the metal sleeve 2, the metal sleeve 2 may be subjected to a heat treatment during the manufacturing process. In addition, the surface may be subjected to a special treatment, such as plating or spraying, to improve its wear resistance and chemical resistance.

Furthermore, it should be appreciated that the design of the metal sleeve 2 allows for ease of installation and possible future maintenance requirements. For example, by designing the connection mode to be convenient to detach, the liquid heat exchange medium or the phase change material in the interior can be easily replaced or maintained when needed.

In the present embodiment of the present invention, in the present embodiment,

In this embodiment, the elastic layer 3 is disposed at intervals with the metal sleeve 2, and is also connected and matched by a plurality of connecting rods 5, so as to form a second annular interlayer, the annular interlayer is filled with a phase change material, a soaking layer 7 is formed by the phase change material, and the soaking layer 7 is a substantially uniform and continuous heat-insulating and thermal-regulating layer. The thickness and density of this layer need to be carefully designed to ensure efficient heat absorption and release at different operating temperatures.

More specifically, the soaking layer 7 is mainly responsible for realizing temperature equalization and stabilization on the surface of the rubber roller in the composite high-elasticity intelligent temperature control rubber roller. This layer allows for stable and uniform transfer of heat to the elastic de-3 via the heat exchange medium during processing by taking advantage of the thermo-physical properties of the phase change material to absorb and release the heat. The soaking layer 7 can form a heat transfer intermediate with balanced temperature, and reduces occurrence of hot spots and cold spots. It will be appreciated that the soaking layer 7 is filled with a phase change material which will change phase when a certain temperature is reached, the phase change material being selected in terms of its phase change temperature, heat storage density, thermal stability and compatibility with other materials of the rubber roller. Conventional phase change materials include paraffin, fatty acids and derivatives thereof, and it should be noted that in some embodiments, in order to increase the heat transfer efficiency of the soaking layer, it may be necessary to add a heat conductive filler, such as a heat conductive nano powder (alumina, boron nitride, etc.), to increase the overall heat conductivity, and ensure that the heat can be rapidly and uniformly distributed over the entire surface of the rubber roll.

In this embodiment, the outer surface of the elastic layer 3 is in direct contact with the working material, providing the necessary elasticity to ensure a uniform pressure distribution during the working process, while also having sufficient wear resistance and chemical resistance to accommodate different industrial environments. In addition, the elastic layer 3 needs to have a certain thermal stability to cope with the temperature change of the rubber roller during operation.

In particular, the elastic layer 3 is a composite structure consisting of an inner support layer 8 and an outer elastic rubber layer 9, which aims to optimize the mechanical and thermal properties of the rubber roller, ensuring its stability and durability under high-speed operation and different temperature conditions.

More specifically, in the present embodiment,

The inner support layer 8 provides structural support, increases strength and stable thermal conductivity, promotes uniform distribution of heat, and reduces hot spots. The material composition is as follows:

epoxy resin (about 50 parts by mass): providing good mechanical strength and adhesion properties.

Glass fiber yarn (about 10 parts by mass): the structural strength of the layer is enhanced, and the wear resistance and tearing resistance are improved. Metal fiber yarn (about 15 parts by mass): further enhancing the mechanical properties of the elastomeric layer, providing additional thermal stability and thermal conductivity.

In this embodiment, the outer elastic rubber layer 9 directly contacts the working material, providing the necessary elasticity to ensure a uniform pressure distribution during the working process. Based on the above-mentioned uses, it is desirable to have high abrasion and chemical resistance, suitable for different industrial environments.

The material composition of the outer elastic rubber layer 9 is as follows:

silicone rubber (60-70 parts by mass): the base elastomer provides excellent temperature resistance and elasticity.

Nanoscale silica powder (5-8 parts by mass): enhances tear strength and abrasion resistance.

Nanoscale alumina powder (15 parts by mass): improving thermal stability and thermal conductivity.

Low molecular weight polydimethylsiloxane (5-7 parts by mass): increasing the softness and processability of the material. Crosslinking agent (1-2 parts by mass): is used for promoting the crosslinking reaction of the silicone rubber and improving the mechanical property of the silicone rubber.

Function and action:

good temperature resistance, and ensures that stability and durability are maintained under temperature changes during operation.

Comprehensive effect of elastic layer

It can be appreciated that through the composite design of the inner support layer 8 and the outer elastic rubber layer 9, the elastic layer 3 not only can provide excellent mechanical strength and stability, but also can meet the requirements of high temperature, high pressure and various chemical environments while guaranteeing the processing precision and quality, so that the composite high-elasticity intelligent temperature control rubber roller can meet the severe requirements of modern industrial processing on high-performance rubber rollers.

In order to realize further temperature control and temperature regulation, in this embodiment, a heating system composed of a plurality of heating wires 10 concentric with the feedback rubber is disposed in the elastic rubber layer 9, and the heating wires 10 are made of a material (such as nichrome) resistant to high temperature, so as to withstand continuous high temperature operation. The heater wires are arranged in a wavy manner along the axial direction of the rubber roller, and the special wiring manner helps to achieve a wider and uniform heating effect. The wave bending design not only increases the surface area of the heating wire, thereby improving the heat transfer efficiency, but also allows the heating wire to provide certain flexibility when the rubber roller expands or contracts, and keeps the performance stable.

Each heater wire 10 is connected to an external controller (not shown) and can be independently controlled by the controller to perform heating. This independent control mechanism allows the rubber roller to achieve different temperature settings in different areas as needed to accommodate complex and varying industrial processing requirements. The controller adjusts the current of each heating wire according to preset temperature parameters or real-time temperature feedback so as to accurately control the heat generated by the heating wires.

As an essential means for achieving temperature control, at least one temperature sensor is distributed inside the elastic rubber layer 9. These sensors are typically designed digitally with high accuracy to accurately measure the temperature of the surface of the rubber roll. In order to ensure the temperature uniformity and accuracy of the whole rubber roller, the temperature sensors are uniformly distributed at different positions of the rubber roller so as to comprehensively monitor the temperature distribution.

The temperature sensor is connected with an external controller and sends temperature information of the surface of the rubber roller to the controller in real time. The controller adjusts the operating state of the heating wire 10 according to the information to ensure that the temperature of the rubber roller is kept within a set range. If the temperature of a region is too high or too low, the controller may increase or decrease the power of the heater wire in that region, thereby rapidly adjusting the temperature. The intelligent temperature control system ensures high precision and repeatability in the processing process, and remarkably improves the product quality and the production efficiency.

Comprehensive effects

Through the real-time supervision of annular cloth wave heater strip 10 and cooperation temperature sensor in elastic rubber layer 9, compound high elasticity intelligence accuse temperature rubber roll has realized high-efficient, even and accurate temperature control. The design not only meets diversified industrial processing requirements, but also improves energy efficiency and product quality, and provides a high-performance, reliable and easily-controlled heating rubber roller solution for users.
