[0039] The working principle and beneficial effects of the above technical solution are: Working principle: On the basis of Example 2, this example adds a description of the working principle of the conveying mechanism 3 and the heat-conducting contact mechanism 6. The electric lifting column 103 can adjust the inclination angle of the sliding platform 105. The active roller 301 in the conveying mechanism 3 rotates under the drive of the driving motor 1 302, and the object to be heated is continuously conveyed to the heating area.

The driving motor 2 603 drives the spur gear 1 604 to rotate, and the spur gear 1 604 meshes and drives the gear ring 1 605 and the heating roller 602 to rotate synchronously.

During a single opening process, the corresponding electromagnetic switch opening signal is simultaneously fed back to the PLC controller 5. One electromagnetic switch controls an independent circulating water temperature control device, and the heating process of the rubber material is enhanced, the number of independent circulating water temperature control devices in operation is increased, and the heating effect on the rubber material is increased.

[0041] After a certain period of time, that is, when the temperature of the original sheet glue reaches stability (the interval control time can be manually controlled and set), the temperature detection probe detects the temperature of the glue again.

During the closing process of a single electromagnetic switch, the corresponding electromagnetic switch closing signal is simultaneously fed back to the PLC controller 5. One electromagnetic switch controls an independent circulating water temperature control device, weakening the heating process of the rubber material, reducing the number of independent circulating water temperature control devices in operation, and weakening the heating effect on the rubber material.

[0044] After a certain period of time, that is, when the temperature of the original sheet glue reaches stability (the interval control time can be manually controlled and set), the temperature detection probe detects the temperature of the glue again. If it is still lower than the standard requirement range, the processing process will continue according to the above logical closed loop.

[0048] Preferably, the first calculation unit calculates the convection heat transfer coefficient of the heating roller 602 in the detection time period based on the data of the flow sensor 1, the temperature detection unit 1, the temperature detection unit 2, and the temperature detection unit 3; A second calculation unit, based on the result of the first calculation unit and the data of the temperature detection unit 4, calculates the evaluation value of the convection heat dissipation loss of the heating roller 602 within the detection time period; The control unit is used to collect and process the data of each detection unit and sensor, thereby adjusting the power and duration of the heating wire tube 204 in the heating tank 202, and adjusting the frequency of the water supply pump 203. The control unit is electrically connected to the temperature detection unit 1, the temperature detection unit 2, the temperature detection unit 3, the temperature detection unit 4 and the alarm respectively; A judgment processing unit, used for comparing and judging whether the evaluation value of the convection heat dissipation loss of the heating roller 602 during the detection time period is within a preset threshold range; The first calculation unit calculates based on the following formula 1: (1); in which: for The convection heat transfer coefficient of the heating roller 602 during the detection period, is the average flow value of the heating liquid in the liquid inlet hose 208 detected by the flow sensor, is the flow rate value of the heated liquid in the return hose 210 detected by the flow rate sensor, For the temperature detection unit The flow temperature value of the heated liquid in the liquid inlet hose 208 detected during the detection period, For temperature detection unit 2 The flow temperature value of the heated liquid in the liquid return hose 210 detected during the detection period, The temperature detection unit 3 detects the average temperature value of the surface of the heating roller 602. is the length of the liquid inlet hose 208, is the length of the return hose 210, is the Reynolds number, which is 107594. is the roughness influence factor of the inner surface of the liquid inlet hose 208 and the liquid return hose 210, and its value is 0.16. is the specific heat of the heated liquid, To heat the liquid The quality of the flow through the heating pipe network 606 during the detection period, The detection end time recorded by the timer, is the initial detection time recorded by the timer, The temperature detection unit 3 detects the maximum operating temperature of the heating roller 602. The minimum operating temperature of the heating roller 602 detected by the temperature detection unit 3; is a logarithmic function, The value of the natural constant is 2.72.

[0049] The second calculation unit calculates based on the following formula 2: (2); in which: is the estimated value of the convection heat dissipation loss of the heating roller 602 during the detection period, is the equivalent diameter inside the heating pipe network 606, for The temperature value of the heating liquid in the heating pipe network 606 detected by the temperature detection unit 2 at the moment, is the equivalent radius of the liquid inlet hose 208, is the length of the liquid inlet hose 208, is the equivalent radius of the return hose 210, is the length of the return hose 210, is the equivalent radius of the heating pipe network 606, is the length of the heating pipe network 606, is the ambient temperature value outside the heating roller 602 detected by the temperature detection unit 29, Take the value of pi as 3.14; The judgment processing unit performs comparative judgment.

When the evaluation value of the convective heat dissipation loss is within the preset threshold range, the expected effect of the heating roller 602 is met. When the evaluation value of the convective heat dissipation loss is greater than the preset threshold, the control unit reduces the frequency of the water supply pump 203 to reduce the heat input into the heating roller 602, and at the same time reduces the power of the heating wire tube 204 and temporarily turns off the heating of the heating wire tube.

At the same time, the PLC controller 5 also evaluates the convection heat dissipation loss of the heating roller 602 through the calculation of the first calculation unit and the second calculation unit. When the evaluation value of the convection heat dissipation loss exceeds the preset threshold value, the PLC controller 5 will timely adjust the power and duration of the heating wire tube 204 in the heating tank 202, as well as the frequency and other parameters of the water supply pump 203, thereby reducing the flow of the heating liquid input to the heating pipe network 606. At the same time, the operator should perform heat preservation treatment on the equipment or increase the temperature of the working environment of the equipment to reduce the convection heat dissipation loss to maintain a stable heating process. When the loss evaluation value of the convection heat dissipation after adjustment still exceeds the preset threshold range after one adjustment, the PLC controller 5 will promptly issue an alarm to promptly remind the maintenance personnel to repair the equipment, dredge the equipment pipeline or replace the parts.
