Description

Technical Field

[0001] The invention relates to the technical field of roller pressing equipment, and in particular to a high-precision pre-embedded contact temperature-controlled pressing roller. Background Art

[0002] The temperature-controlled roller is a roller that integrates temperature control and pressure application functions. It uses the built-in temperature control system to accurately control the roller surface temperature, and uses the roller to apply a certain amount of pressure to the material to achieve a specific processing effect. The commonly used temperature control detection methods on the market currently include contact laser infrared probes, thermal imaging, etc., but these temperature measurement methods have the following problems: laser infrared probes and thermal imaging detection are easily affected by factors such as ambient temperature, humidity, and airflow, resulting in fluctuations or deviations in measurement results. In addition to being easily affected by environmental factors, laser infrared probes may also cause errors in measurement results due to the different emissivity of different materials. Therefore, when using an infrared thermometer, it is necessary to Understand the emissivity of the object to be measured and make corresponding settings in advance. At the same time, the size of the measured object and the measuring distance are required to be high. The measurement accuracy of small-sized or long-distance targets will also be affected. The Chinese patent application number 202410093064 discloses a pressure roller assembly using wireless temperature control technology. The technical solution of this patent adopts an eccentric shaft and a bearing installed in the pressure roller shell. The eccentric shaft passes through the bearing, and a temperature control component is installed on the outer wall of the eccentric shaft for detection. However, due to the assembly gap between the eccentric shaft and the bearing, the temperature control component is easily displaced when the pressure roller rotates at high speed, resulting in inaccurate temperature detection. Summary of the invention

[0003] The purpose of the present invention is to provide a high-precision pre-embedded contact temperature control pressure roller to solve the problem that the eccentric shaft and the bearing of the prior art proposed in the above background technology have an assembly gap, and the temperature control component is easily displaced when the pressure roller rotates at high speed, resulting in inaccurate temperature detection.

The heat-conducting roller body 100 is provided with a transmission system 300 at one end, and the transmission system 300 is used for power transmission and signal transmission of the heat-conducting roller body 100; the heat-conducting roller body 100 is a circular shaft body, and a rotating shaft 110 with a smaller diameter than the circular shaft body of the heat-conducting roller body 100 is provided at both ends. The heat-conducting roller body 100 is provided with a temperature regulation system inside, and the temperature regulation system is used to adjust the temperature of the heat-conducting roller body 100. The outer ring 120 of the heat-conducting roller body is provided with a temperature detection system 200 in the roller, and the temperature detection system 200 is used to detect the temperature of the heat-conducting roller body 100. The temperature detection system 200 comprises a temperature sensor 220, and the temperature sensor is in direct contact with the inside of the heat-conducting roller body 100.

[0026] like Figure 1-2 As shown, the circular shaft body of the heat-conducting roller body 100 is in a two-step stepped shape, the outer ring 120 of the heat-conducting roller body has a large diameter and a short length, and is provided with a plurality of mounting holes 210 therein, the mounting holes 210 being blind holes, the open end of the mounting holes 210 being the side of the heat-conducting roller body 100 close to the transmission system 300, and the closed end being the other side of the heat-conducting roller body 100; the plurality of mounting holes 210 are evenly distributed along the circumference of the outer ring 120 of the heat-conducting roller body, and the mounting holes 210 are directly opened on the outer ring 120 of the heat-conducting roller body to install the temperature sensor 220, which solves the problem of inaccurate temperature measurement caused by displacement of the temperature sensor 220 when the heat-conducting roller body 100 rotates at high speed.

[0027] In actual production, the temperature sensor 220 includes a plurality of thermocouple temperature measuring probes, which are arranged at multiple points on the outer ring 120 of the heat-conducting roller body according to design requirements and are in direct contact with the heat-conducting roller body 100.

[0028] like Figure 1 As shown, the opening direction of the plurality of mounting holes 210 is parallel to the axial direction of the heat-conducting roller body 100 , and extends from one side of the heat-conducting roller body 100 close to the transmission system 300 to the other side.

[0029] like Figure 3As shown, the outer ring 120 of the heat-conducting roller body is provided with three mounting holes 210 along the circumferential direction, and the opening direction of the three mounting holes 210 is parallel to the axial direction of the heat-conducting roller body 100, extending from one side of the heat-conducting roller body 100 close to the transmission system 300 to the other side, and the three mounting holes 210 are closed at one end away from the transmission system 300 and open at one end close to the transmission system 300, and the three mounting holes 210 are all installed with the temperature sensor 220, one end of the temperature sensor 220 is completely extended into the mounting hole 210, and the other end is electrically connected to the transmission system 300 through the opening of the mounting hole 210.

[0030] A second embodiment of the present invention is that the plurality of mounting holes 210 are spirally arranged around the heat-conducting roller body 100 , extending from one side of the heat-conducting roller body 100 close to the transmission system 300 to the other side.

[0031] In actual production, the temperature regulation system includes a medium inlet, a medium outlet and a medium circulation channel, and the channel is used to transport the medium into the heat-conducting roller body 100 so that the heat-conducting medium can flow evenly through the entire heat-conducting roller body 100, thereby achieving uniform heat transfer.

[0032] In actual production, the medium is oil, which is used to heat up or cool down the heat-conducting roller 100. The oil circulates inside the heat-conducting roller 100 and can directly take away the heat inside the heat-conducting roller 100, thereby improving the heat dissipation efficiency, making the roller surface temperature of the heat-conducting roller 100 more uniform, and avoiding the concentration of thermal stress and deformation of the heat-conducting roller 100 caused by local overheating.

[0033] In actual production, the control unit is arranged outside the heat-conducting roller body 100, and is used to receive the detection result of the temperature detection system 200. When the detection result reaches the design value, the control unit sends a cooling signal to the temperature regulation system, and the temperature regulation system reduces the internal temperature of the heat-conducting roller body 100.

[0034] In actual production, the transmission system 300 includes an inner hollow slip ring 310 and an outer hollow slip ring 320. The inner hollow slip ring 310 is sleeved on the rotating shaft 110 and is attached to and fixed at one end of the circular shaft of the heat-conducting roller body 100, serving as an input end for current and signals; the outer hollow slip ring 320 rotates with the rotation of the heat-conducting roller, serving as an output end for current and signals.

[0035] In actual production, the control unit is electrically connected to the inner and outer hollow slip rings 320; the inner hollow slip ring 310 is electrically connected to the temperature detection system 200; the outer hollow slip ring 320 and the temperature adjustment system are electrically connected to monitor and adjust the temperature of the heat-conducting roller 100 in real time to ensure temperature stability and uniformity during the production process.

[0036] The working principle of the present invention is as follows:

[0037] The pressure roller is started, and the heat-conducting roller body 100 begins to heat up and rotate. The outer hollow slip ring 320 keeps in contact with the inner hollow slip ring 310. The current of the inner hollow slip ring 310 is transmitted to the outer hollow slip ring 320 through the brush, and then further transmitted to the heat-conducting roller body 100. At the same time, the temperature sensor 220 of the temperature detection system 200 transmits the real-time detected temperature data to the control unit through the inner hollow slip ring 310. When the control unit determines that the temperature reaches or exceeds the design value, it sends a cooling signal to the temperature control system, and the temperature control system is immediately started to reduce the temperature inside the heat-conducting roller body 100 by adjusting the flow rate of the medium.

[0038] It should be understood that the above-mentioned embodiments are one or more embodiments of the present invention, and there are many other embodiments and variations thereof based on the present invention; the variations and modifications made by ordinary technicians in this industry through the present invention without making pioneering innovations all fall within the scope of protection of the present invention.
