Description

Technical Field

[0001] This utility model relates to the field of calender roll temperature control technology, specifically to a calender roll temperature uniformity control device. Background Technology

[0002] Calendering rolls are the core components of a calendering mill used to apply pressure and stretch materials (such as rubber, plastics, or thin metal sheets) into shape. They are typically made of high-hardness alloys and have precise dimensions and surface finishes. The rolls achieve material thickness adjustment or composite processing through rotation and temperature control. Their arrangement and configuration directly affect the uniformity and quality of the calendered products, and they are widely used in tire manufacturing, plastic film production, and lithium battery electrode processing.

[0003] Traditional calenders often embed electric heating tubes inside the rollers to control the temperature. However, the continuous operation of these heating tubes leads to high energy consumption and localized overheating, resulting in poor temperature uniformity. Consequently, this can cause a decrease in the yield rate of some products during processing. Utility Model Content

The side of the heat transfer oil tank away from the circulating pump is fixedly connected to a hose two. The ends of hose one and hose two are detachably connected to the ends of the two fixed pipe ports, respectively.

[0013] The above technical solution allows for the circulation of heat transfer oil by controlling the operation of the circulating pump.

A strip top plate is fixedly installed on the top of the strip frame, and a fan is fixedly connected to the top of the strip top plate.

[0017] By controlling the operation of the fan, heat dissipation air can be blown onto the surface of the roller body, reducing the impact of abnormal temperature on the material.

[0018] As a preferred embodiment of the above technical solution, a perforated plate is fixedly installed at the bottom of the strip frame, and an infrared temperature sensor is fixedly installed at the bottom of the perforated plate.

[0019] Through the above technical solution, the infrared temperature sensor can monitor the temperature of the roller body surface and be used to automatically control the operation of the fan.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a rolling mill roller temperature uniformity control device, comprising:

[0030] Support base 1 and support base 2;

[0031] Uniform temperature control mechanism 2 is installed on support base 1 and support base 2 11. Uniform temperature control mechanism 2 is used to heat the product uniformly.

[0032] Redundant protection mechanism 3 is installed on support base 1 and support base 2 11. Redundant protection mechanism 3 is used for cooling protection.

[0033] The uniform temperature control mechanism 2 includes a roller body 21. Hollow rotating shafts 22 are fixedly connected to both ends of the roller body 21. The two hollow rotating shafts 22 are rotatably connected to the inner walls of support base 1 and support base 21, respectively. Rotary joints 24 are rotatably connected to the ends of the hollow rotating shafts 22. A fixed pipe port 25 is fixedly connected to the end of the rotary joint 24 away from the hollow rotating shaft 22. A support sleeve 23 is fixedly sleeved on the outer wall of the fixed pipe port 25. The two support sleeves 23 are fixedly installed on the outer walls of support base 1 and support base 21, respectively. Through the design of the hollow rotating shafts 22, support sleeves 23 and rotary joints 24, the roller body 21 is rotatably connected between support base 1 and support base 21. At the same time, the fixed pipe port 25 is fixed on support base 1 and support base 21. The constant temperature heat transfer oil can flow through the inner cavity of the roller body 21 from the fixed pipe port 25 without interfering with the rotation of the roller body 21, which facilitates uniform temperature control.

[0034] As one implementation method in this embodiment, such as Figure 3 As shown, an inner support plate 211 is fixedly installed on the inner wall of the roller body 21. The number of inner support plates 211 is set to two. An inner cylinder 212 is fixedly installed between the adjacent sides of the two inner support plates 211. Through the design of the inner support plate 211 and the inner cylinder 212, the middle part of the inner cavity of the roller body 21 can be filled, reducing the amount of heat transfer oil used.

[0035] As one implementation method in this embodiment, such as Figure 4 As shown, the uniform temperature control mechanism 2 also includes a heat transfer oil tank 26 and a circulation pump 27. The heat transfer oil tank 26 is fixedly installed on the top of the support base 1, and the circulation pump 27 is fixedly installed on the top of the support base 1. The output end of the circulation pump 27 is fixedly connected to a hose 28, and the input end of the circulation pump 27 is fixedly connected to the side of the heat transfer oil tank 26. A hose 29 is fixedly connected to the side of the heat transfer oil tank 26 away from the circulation pump 27. The ends of hoses 28 and 29 are detachably connected to the ends of two fixed pipe ports 25, respectively. The actual lengths of hose 28 and hose 29 are designed according to the usage environment. The operation of the circulating pump 27 can draw the constant temperature heat transfer oil inside the heat transfer oil tank 26 and then transport it through hose 28 to the roller body 21. The heat transfer oil in the roller body 21 will flow back to the heat transfer oil tank 26 through hose 29, realizing the circulation of heat transfer oil. The heat transfer oil flows through the inner cavity of the roller body 21, which realizes the function of uniformly heating the roller body 21, improving the uniformity of temperature control and ensuring the yield of product processing.

[0036] As one implementation method in this embodiment, such as Figure 4 As shown, a cover plate 261 is detachably connected to the top of the heat transfer oil tank 26. A controller 262 is fixedly installed on the top of the cover plate 261, and a digital thermometer 263 is fixedly installed on the bottom of the cover plate 261. An electric heating element 264 is also fixedly installed on the bottom of the cover plate 261. The electric heating element 264 heats the circulating heat transfer oil. The digital thermometer 263 measures the temperature of the circulating heat transfer oil, and the temperature data is fed back to the controller 262. When a threshold is reached, the controller 262 will control the electric heating element 264 to stop working, thus achieving the function of maintaining a constant temperature for the heat transfer oil. Because the electric heating element 264 operates non-continuously, the problem of high energy consumption caused by continuous operation of the heating element is avoided. It is worth noting that the controller 262 in this solution... 62. The digital thermometer 263 and the electric heating element 264 are commercially available devices that can be purchased by those skilled in the art. No structural modifications have been made to these devices in this document. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and are able to apply them proficiently. Thus, this document will not elaborate further on them. Furthermore, this solution aims to protect the physical structure, not the circuitry or software control. The mention of the processing circuit in this document is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0037] As one implementation method in this embodiment, such as Figure 5 As shown, the redundancy protection mechanism 3 includes a strip frame 31, which is fixedly installed between support base 1 and support base 2. A strip top plate 34 is fixedly installed on the top of the strip frame 31, and a fan 35 is fixedly connected to the top of the strip top plate 34. When the components included in the uniform temperature control mechanism 2 are damaged, the temperature of the heat transfer oil may rise abnormally. At this time, the fan 35 is controlled to work, which can blow heat dissipation air onto the surface of the roller body 21 to reduce the impact of abnormal temperature on the material, prevent problems such as roller sticking, and facilitate timely handling by the staff.

[0038] As one implementation method in this embodiment, such as Figure 5 As shown, a perforated plate 32 is fixedly installed at the bottom of the strip frame 31, and an infrared temperature sensor 33 is fixedly installed at the bottom of the perforated plate 32. Through the design of the infrared temperature sensor 33, the temperature of the surface of the roller body 21 can be monitored, and the temperature data is fed back to the controller 262. When the threshold is reached, the controller 262 will control the fan 35 to work for cooling protection. The infrared temperature sensor 33 is an existing structure. The air output by the fan 35 will pass through the perforated plate 32 and be evenly sprayed onto the roller body 21.

[0039] Working principle: During use, the circulating pump 27 is controlled to operate, which can draw the constant temperature heat transfer oil inside the heat transfer oil tank 26 and then deliver it through the first hose 28 to the roller body 21. The heat transfer oil in the roller body 21 will flow back to the heat transfer oil tank 26 through the second hose 29, realizing the circulation of heat transfer oil. The electric heating component 264 is controlled to operate, which can heat the circulating heat transfer oil. The temperature of the circulating heat transfer oil is measured by the digital thermometer 263, and the temperature data is fed back to the controller 262. When the threshold is reached, the controller 262 will control the electric heating component 264 to stop working, thus realizing the function of constant temperature of heat transfer oil. The heat transfer oil flows through the inner cavity of the roller body 21, thus realizing the function of uniform heating of the roller body 21. At the same time, the infrared temperature sensor 33 monitors the surface temperature of the roller body 21, and the temperature data is fed back to the controller 262. When the threshold is reached, the controller 262 will control the fan 35 to operate for cooling protection.

[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
