Description

Technical Field

[0001] The invention relates to the technical field of rubber heating pretreatment, and in particular to a step-adjustable self-feedback system and a corresponding structural device thereof. Background Art

[0002] During the action of the extruder on the rubber material, the rubber material (original rubber sheet) is originally in a highly elastic state. The feeding mechanism conveys the rubber material into the barrel, and the screw shears, heats and plasticizes the rubber material, and keeps it at a certain temperature through the heating system of the extruder barrel. As the screw rotates and propels it, it gradually transforms into a molten state. However, in production, the extruder's poor thermal plasticization of the original rubber sheet leads to quality problems in the extrusion of semi-components, affecting the product delivery efficiency, stability and process operation control of subsequent processes.

[0003] The prior art directly uses an extruder to process the rubber material, and there is no rubber material pretreatment device. In production, there are problems such as poor heat plasticization of the original rubber sheet by the extruder, which leads to quality problems in the extrusion of semi-components, affecting the stability of product quality and the process operation control of subsequent processes; secondly, for the adjustment of the rubber material during the pretreatment heating process, the traditional adjustment method cannot perform step adjustment and cannot self-adjust and optimize the feedback signal, especially in situations that require precise control and rapid response.

[0028] Preferably, the circulating water temperature control mechanism 4 includes: a tank body 11, the tank body 11 is fixedly mounted on the top of the mounting plate 1, a heating tube 12 is mounted inside the tank body 11, a water outlet of a cooling water pipe 13 is connected to a water inlet of cooling water of the tank body 11, a water pump 14 is fixedly connected to the cooling water pipe 13, and the cooling water pipe 13 is fixedly connected with an electromagnetic proportional valve 15 near the tank body 11, and a second temperature detection probe 16 is fixedly mounted on the inner wall of the tank body 11.

[0029] Preferably, it also includes a water inlet pipe 17 and a water return pipe, the water outlet of the tank body 11 is connected to the water inlet of the heating roller 5 through the water inlet pipe 17, and the water inlet of the tank body 11 is connected to the water outlet of the heating roller 5 through the water return pipe 18.

[0030] The working principle and beneficial effects of the above technical solution are: The above-mentioned rubber pretreatment device completes the heating pretreatment of the rubber based on the above-mentioned device by setting the second temperature detection probe 16, the electromagnetic proportional valve 15, the heating roller 5 and the driving motor 8, the gear 9, the circulating water temperature control mechanism 4, etc. for driving the heating roller to rotate, wherein the rubber runs along the feeding conveyor belt 3, realizing the feeding and transportation process, the circulating water temperature control mechanism 4 transports the circulating heated water along the pipeline and transports it to the heating roller 5, the heating roller 5 is heated up and heat exchange is carried out with the rubber, thereby realizing the heating pretreatment of the rubber.

[0031] When the above-mentioned rubber pretreatment device is performing heating pretreatment operations, the circulating water used for heating is powered by the water pump 14 and enters the tank body 11 along the cooling water pipe 13. The rotary joint 7 arranged at one end of the heating roller 5 cooperates with the driving motor 8 and the gear 9 to realize the rotation of the heating roller 5 along the fixed plate 6, thereby realizing the heating pretreatment of the rubber. The return pipe 18 is used to transport the circulating water in the heating roller 5 back to the tank body 11; the heating pipe 12 arranged inside the tank body 11 can heat the circulating water in the tank body 11 as needed, and the cooling water pipe 13 is fixedly connected to the electromagnetic proportional valve 15 near the tank body 11 to control the circulating water entering the tank body 11.

[0032] The above-mentioned rubber pretreatment device works under the step-adjustable self-feedback system. First, the first temperature detection probe 10 detects the temperature of the rubber. The detected temperature is transmitted as an input signal to the step-adjustable self-feedback system to determine whether it is within the standard requirement range. If it is lower than the standard requirement range, it is then fed back to the step-adjustable self-feedback system to transmit a signal to the frequency converter connected to the heating tube 12 in the circulating water temperature control mechanism 4. The frequency converter controller controls the power of the heating tube 12 to increase the temperature of the circulating water in the tank body 11. The temperature of the circulating heating water increases, which drives the heating effect of the heating roller 5 to increase, thereby achieving the effect of increasing the temperature of the rubber. Among them, the progressive increase in power of the heating tube 12 controlled by the step-adjustable self-feedback system can be manually controlled and set; after a certain interval of time, that is, when the temperature of the rubber (original sheet rubber) reaches stability (the interval control time can be manually controlled and set, such as 3 minutes), the first temperature detection probe 10 is again The temperature of the rubber material is detected. If it is still higher than the standard requirement range, the processing process is continued according to the above logical closed loop. When the detected temperature is higher than the standard requirement range, the step-adjustable self-feedback system transmits a signal to the cooling water electromagnetic proportional valve 15 controller of the circulating water temperature control mechanism 4, and the opening of the electromagnetic proportional valve 15 increases. At the same time, the water pump 14 receives the signal and works to provide power to the cooling water. The cooling water enters the tank body 11, driving the circulating cooling water temperature to decrease, thereby driving the heating effect of the heating roller 5 to decrease, so as to achieve the effect of lowering the rubber material temperature. The step-adjustable self-feedback system controls the electromagnetic proportional valve 15 to increase the opening each time, which can be manually controlled and set. Finally, after a certain interval, that is, the rubber material (original sheet rubber) temperature reaches stability (the interval control time can be manually controlled and set), the first temperature detection probe 10 detects the rubber material temperature again. If it is still lower than the standard requirement range, the processing process is continued according to the above logical closed loop.

[0033] The above-mentioned rubber pretreatment device cooperates with the step-adjustable self-feedback system to control the temperature of the progressive circulating water, thereby controlling the heating effect of the heating roller 5 on the rubber.
