A barrel is arranged below the rubber hot feeding device, a discharge screw is arranged in the barrel, a flange that can be connected to the extrusion die is arranged at one end of the barrel, and the extrusion die is connected to the flange. The rubber hot feeding device includes: a funnel-shaped feed barrel, a feed port is arranged at the upper end of the feed barrel, and a discharge port is arranged at the lower end of the feed barrel. The feed barrel is connected to the barrel through the discharge port. After the rubber compound after mixing enters the feed barrel, it is transported to the barrel from the discharge port. The discharge screw rotating in the barrel extrude and shear the rubber compound, and at the same time transports the rubber compound to the flange direction. The rubber compound extruded and sheared by the discharge screw enters the extrusion die through the flange. The rubber compound is extruded and formed while cooling in the extrusion die, thereby forming the desired product.

The rubber strips fed into the hot feed extruder must first be heat-refined in an open mixing mill. However, the current open mixing mill is unable to achieve the temperature control process for the rubber strips fed into the extruder, resulting in temperature differences in the rubber strips fed into the extruder. The size of the extrudate is easily affected by the change in the temperature of the rubber strips and fluctuates, which in turn causes deviations in the size of the extrudate.

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

Through the cooling mechanism 4, temperature probe 6 and PLC module, the detected temperature of the temperature probe 6 can be transmitted to the PLC module as an input signal, and the PLC module determines whether it is within the standard requirement range. If it is not within the standard requirement range, the signal is transmitted to the cold water pipe proportional valve 20 or the hot water pipe proportional valve 17 through the PLC module, and the opening is controlled by the cold water pipe proportional valve 20 and the hot water pipe proportional valve 17 to realize the adjustment of the water temperature in the water tank 18, and then the roller temperature of the cooling roller 12 is adjusted, so that the film temperature is adjusted by the cooling roller 12, and the temperature control process of the supply film is realized. The temperature control process is precisely controlled and the temperature control speed is fast, which improves the stability of the extrusion size of the extrudate, is beneficial to the improvement of product stability, and the device is set in the open air, which is convenient for operators to observe the reaction dynamics at any time, and is convenient for adjustment and maintenance.

Specifically, in this embodiment, the first mixing mill 1 and the second mixing mill 3 both include a servo motor 21 , a coupling 22 and a calendering roller 5 .

The servo motor 21 can drive the coupling 22 to rotate, so that the calendering roller 5 can be driven to rotate through the coupling 22 .

Specifically, in this embodiment, a rotary joint 11 is connected to the cooling mechanism 4, a water inlet pipe 9 is connected to the rotary joint 11, a water return pipe 10 is arranged on the water inlet pipe 9, a cooling roller 12 is arranged on the cooling mechanism 4, the cooling roller 12 is connected to the water inlet pipe 9 and the water return pipe 10, 12 water flow channels 15 are evenly arranged along the circumferential direction in the cooling roller 12, and the water flow channels 15 are connected to the water inlet pipe 9 and the water return pipe 10.

Through the provided water inlet pipe 9 and water return pipe 10, water in the water storage tank 18 can be transported to the water inlet pipe 9 through the main pump 19, and the water can be transported to the cooling roller 12 through the water inlet pipe 9 to adjust the roller temperature of the cooling roller 12.

Specifically, in this embodiment, a mounting bracket 13 is arranged on the second conveyor belt 7 , and the temperature measuring probe 6 is disposed on the mounting bracket 13 .

When in use, the film is heat-refined through the first open mixing mill 1. After the heat-refining, the film is led to the first conveyor belt 2 for the rubber film to be transported, and the film is transported to the second open mixing mill 3 for secondary heat-refining of the film. The temperature of the film is detected by the temperature detection probe on the second conveyor belt 7 to detect whether the conveying temperature of the rubber film meets the standard requirements. After the detection is completed, the rubber film is transported along the second conveyor belt 7 to the extruder feeding port hopper 8.

When the temperature detection probe detects the temperature of the glue supply film, the detected temperature is sent to the PLC module as an input signal, and the PLC module determines whether it is within the standard requirement range. If it is within the standard requirement range, the cold water pipe proportional valve 20 and the hot water pipe proportional valve 17 are opened to maintain the current operating state;

Cold water and hot water are pumped into the water storage tank by the cold water pump 14 and the hot water pump 16 respectively. The water in the water storage tank is pumped into the water inlet of the cooling roller 12 by the main pump 19 to adjust the roller temperature of the cooling roller 12.

If the temperature detected by the temperature detection probe is higher than the standard range requirement, the PLC module transmits a signal to the cold water pipe proportional valve 20, so that the opening of the cold water pipe proportional valve 20 increases, thereby reducing the water temperature entering the cooling roller 12, and then reducing the roller temperature of the cooling roller 12. The rubber film contacts the cooling roller 12 and the rubber film is cooled. After the stabilization time, if the detected temperature is still higher than the standard requirement, the PLC module transmits a signal to the proportional valve, and the opening of the cold water pipe proportional valve 20 continues to increase step by step until the opening reaches the maximum. If the detected temperature is still higher than the standard requirement range, the PLC controls the hot water pipe proportional valve 17 to reduce the opening. In any of the above operating steps, if the temperature detection probe reaches the standard requirement range, the operating process is terminated.

When it is lower than the standard range requirement, the operating state and control method are opposite to the above. The PLC module transmits a signal to the hot water pipe proportional valve 17, so that the opening of the hot water pipe proportional valve 17 increases, thereby increasing the water temperature entering the cooling roller 12, and driving the roller temperature of the cooling roller 12 to increase. The rubber film contacts the cooling roller 12, and the rubber film is cooled. After the stabilization time, if the detected temperature is still lower than the standard requirement, the PLC module transmits a signal to the hot water pipe proportional valve 17, and the opening of the hot water pipeline proportional valve continues to increase step by step until the opening reaches the maximum. If the detected temperature is still lower than the standard requirement range, the PLC controls the cold water pipe proportional valve 20 to reduce the opening. In any of the above operating steps, when the temperature detection probe reaches the standard requirement range, the operating process is terminated.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
