[0002] The process of an extruder acting on rubber compound: The rubber compound (raw rubber) is originally in a highly elastic state. The feeding mechanism conveys the rubber compound into the barrel. The screw shears, heats, and plasticizes the rubber compound, and the heating system of the extruder barrel maintains it at a certain temperature. As the screw rotates and propels the compound, it gradually transforms into a molten state.

The top of the rack 25 is equipped with a distance measuring sensor 23 on both sides. The top of the rack 25 is equipped with a first temperature detection probe 12 on both sides. The outside of the rack 25 is equipped with a servo motor and its controlled telescopic rod 11 on both sides.

The inside of the rack is equipped with a guide roller, which is located directly below the heating roller.

[0033] Please refer to Figure 4 and Figure 5 The inside of the heating roller 3 can supply hot water to heat the plate. The rotary joint 9 can rotate outside the heating roller 3 to avoid resistance when the heating roller 3 rotates. The first bearing 10 can support the movement of the bracket 13 outside the first bearing 10. The servo motor and its controlled telescopic rod 11 and the servo motor and its telescopic structure 18 for controlling the operation of the push rod are common mechanical telescopic arms in the prior art, which are composed of control equipment, cylinders and sensors inside, used to drive the bracket 13 and the heating roller 3 to rotate, control the movement trajectory of the heating roller 3, detect the temperature with the first temperature detection probe 12 and the second temperature detection probe 20, control the movement of the transmission components inside the device with the PLC module 24, control the water temperature with the heating wire tube 21, and drive the water flow to move with the water pump 22. The distance measuring sensor 23 can detect the position of the heating roller 3.

[0034] The second temperature detection probe 20 detects the temperature of the circulating water in the cylinder, and transmits the signal to the PLC module 24 of the circulating water temperature control device 17. The PLC module 24 receives the signal and determines whether it is within the standard required range. If it is higher than the standard required range, the PLC module 24 transmits a signal to the heating wire tube 21 to stop running, and relies on external heat exchange to cool the circulating heating water. If it is lower than the standard required range, the PLC module 24 transmits a signal to the heating wire tube 21 to run, and heats the circulating water, so as to maintain the temperature of the heating circulating water in the heating roller 3 within the standard required range.

[0035] The heating circulating water is powered by the water pump 22, runs along the circulating heating water port 8, and finally reaches the inside of the heating roller 3. The heating roller 3 has a rotary joint 9 at both ends, and is fixed on the connecting rod of the support 13 through the rotary joint 9. The support 13 is fixedly connected to the linkage line, and plays a role in supporting the heating roller 3 during the up-down operation of the control roller. The heating roller 3 is powered by the motor set 14 and rotates through the gear 15, realizing the rotation of the heating roller 3.

[0036] The first temperature detection probe 12 detects the temperature of the rubber material, and transmits the detection temperature as an input signal to the PLC module 24 to determine whether it is within the standard required range. If it is lower than the standard required range, the PLC module 24 transmits a signal to the frequency converter, and the frequency converter controls the servo motor and the telescopic rod 11 controlled thereby to provide power to make the telescopic rod go up. Through the action of the support 13 and the first bearing 10, the heating roller 3 is driven to go down and the contact distance with the rubber material is reduced. At the same time, the PLC module 24 transmits a signal to the servo motor and the telescopic rod 11 controlled thereby under the conveying belt, and drives the telescopic rod to move oppositely, so as to improve the heat exchange efficiency and achieve the effect of improving the temperature of the rubber material.

[0037] The telescopic rod is provided with a distance measuring sensor 23, and the moving distance in a single unit time can be artificially controlled and set. When the corresponding single moving set distance in a unit time is reached, the distance measuring sensor 23 transmits a signal to the PLC module 24, and the PLC module 24 transmits a signal to the frequency converter to control the servo motor and the telescopic rod 11 controlled thereby to stop going up.

[0038] After a certain interval of time, i.e. after the temperature of the original rubber reaches stability, the interval control time can be artificially controlled and set, such as 3 minutes. The first temperature detection probe 12 detects the temperature of the rubber material again. If it is still lower than the standard required range, the process is continued according to the above logic closed loop.

[0039] If higher than the standard requirement range, then the PLC module 24 transmits a signal to the frequency converter, the frequency converter controls the servo motor and the telescopic rod 11 controlled thereby, the servo motor and the telescopic rod 11 controlled thereby provide power to make the telescopic rod descend, through the action of the support 13 and the first bearing 10, thereby driving the heating roller 3 to descend and the contact distance with the rubber compound to increase, at the same time, the PLC transmits a signal to the servo motor and the telescopic rod 11 of the left and right horizontal push rod under the conveying belt, the servo motor and the telescopic rod 11 controlled thereby control the servo motor and drive the telescopic rod to move reversely, the heat exchange efficiency is reduced, thereby achieving the effect of reducing the temperature of the rubber compound.

[0040] The telescopic rod is provided with a distance measuring sensor 23, the moving distance in a single unit time can be artificially controlled and set, when the corresponding single moving set distance in a unit time is reached, the distance measuring sensor 23 transmits a signal to the PLC module 24, the PLC module 24 transmits a signal to the frequency converter, and controls the servo motor to stop descending.

[0041] After a certain interval, that is, after the temperature of the original rubber compound reaches stability, the interval control time can be artificially controlled and set, for example, 3 minutes, the first temperature detection probe 12 detects the temperature of the rubber compound again, if it is still higher than the standard requirement range, then the processing process is continuously carried out according to the above logic closed loop.
