The feeding augers 5051 are rotatably connected in the tail conveying assembly 501.

[0030] The working principle and beneficial effects of the above technical solution are as follows: the rubber material 100 after the primary heating pretreatment enters the secondary heating pretreatment component box 500 through the feed port 5000, and then the power motor 502 starts to drive the input shaft 5020 to rotate back and forth, driving the material mixing paddle 504 to rotate to stir the rubber material 100, and at the same time, the switching gear 5021 links the extrusion piston 5030 to push and pull back and forth. When the extrusion piston 5030 moves to the right, the hot air in the heating component 300 is sucked into the hot air box 503. When the extrusion piston 5030 moves to the left, the hot air in the hot air box 503 is pressed out to the rubber material 100 through the heat exhaust plate 5033. The rubber material 100 is pre-heated for the second time. During this process, the angle of the heat exhaust plate 5033 can be adjusted by extending and retracting the push-pull cylinder 5035 to avoid uneven heating. After the heating is completed, the switching cylinder 5023 drives the switching gear 5021 to engage with the meshing gear 2 5050, and the power motor 502 drives the input shaft 5020 and the switching gear 5021 to rotate, the switching gear 5021 drives the meshing gear 2 5050 to rotate, and the meshing gear 2 5050 drives the feed auger 1 5052 to rotate, and the rubber material 100 is transmitted to the rear conveying component 501, and then output to the extruder through the feed auger 2 5051.

A U-shaped rod 5046 is fixedly connected to the mounting slider 5045. The end of the U-shaped rod 5046 away from the mounting slider 5045 is rotatably connected to a swing gear 5047. The swing gear 5047 is coaxially fixedly connected to a position adjusting cylinder 5048.

[0032] The working principle and beneficial effects of the above technical solution are as follows: when working, the switching cylinder 5023 drives the switching gear 5021 to mesh with the meshing gear 1 5040, the power motor 502 drives the input shaft 5020 and the switching gear 5021 to rotate, the switching gear 5021 drives the meshing gear 1 5040 to rotate, the meshing gear 1 5040 drives the winding wheel 5041 to reciprocate, the winding wheel 5041 drives the winding 5012 to reciprocate and pull the installation slider 5045 to move left and right, and the installation slider 5045 pulls the extrusion piston 5030 during the left and right movement. Reciprocating motion is used to squeeze out the hot air. At the same time, the sliding block 5045 is installed to move left and right to drive the U-shaped rod 5046 to move left and right. Since the swing gear 5047 and the linkage rack 5044 are meshed with each other, the swing gear 5047 is driven to roll along the linkage rack 5044 during the left and right movement of the U-shaped rod 5046, thereby realizing the left and right swing of the pendulum connecting rod 5049, and hammering the rubber material 100. In this process, the spatial position of the pendulum 505 can be changed by extending and retracting the position adjustment cylinder 5048, so as to realize the all-round hammering of the rubber material 100. Through the design of the material-scratching assembly, the slide rail 5043, the linkage rack 5044, the mounting slide block 5045 and other components, uniform stirring and hammering of the rubber material is achieved, further improving the quality of the heating pretreatment.

[0033] Example 8 On the basis of Example 1, a temperature control component is also included, which includes a temperature sensor 1 5011, a temperature sensor 2 5010 and a controller, and the controller is electrically connected to the temperature sensor 1 5011, the temperature sensor 2 5010 and the primary heating pretreatment component 301.

[0034] The working principle and beneficial effects of the above technical solution are as follows: Specifically, the temperature sensor 5010 detects the temperature of the rubber material 100, and the detected temperature is transmitted to the controller as an input signal to determine in which temperature range it is located, and then determine the corresponding operation mechanism. According to the actual detected temperature T1, the corresponding operation scheme adopted is determined (the corresponding action temperature range and the corresponding operation scheme mechanism can be manually set and modified to meet the actual production needs), such as: When 34℃≤detection temperature T1≤39℃, that is, it is within the standard temperature requirement range, adopt scheme 4, that is, maintain the existing rotating partition position state; If it is lower than the standard requirement range, the controller transmits a signal to the frequency converter, the frequency converter controls the regulating motor 3014, the regulating motor 3014 drives the rotary plate 3011 to rotate along the rotary plate slideway 3013 toward the direction of increasing the opening of the heating roller exhaust hole 3010, the angle sensor 3015 measures the rotation angle, and after reaching the rotation angle set by the control, the angle sensor 3015 transmits the angle measurement value to the controller, the controller transmits a signal to the frequency converter, the frequency converter controls the regulating motor 3014 to stop running, the heat exchange efficiency is improved, thereby achieving the effect of increasing the temperature of the rubber material, the controller rotates the rotary plate 3011 each time The rotation angle can be manually set, the specific operation plan is as follows: When 29℃≤detection temperature T1<34℃, adopt scheme 3, that is, increase the angle of the existing rotating plate 3011 by 3 degrees (for example, the existing partition angle is 20 degrees, increase it to 23 degrees); When 24℃≤detection temperature T1<29℃, adopt scheme 2, that is, increase the angle of the existing rotating plate 3011 by 5 degrees (for example, the existing partition angle is 20 degrees, increase it to 25 degrees); When the detected temperature T1 is less than 24°C, adopt solution 1, that is, increase the angle of the existing rotating plate 3011 by 7 degrees (for example, the existing partition angle is 20 degrees, which is increased to 27 degrees); After a certain period of time, that is, when the temperature of the original sheet of glue reaches stability (the temperature difference between adjacent detection moments of the temperature sensor 5010 is used to determine whether the temperature of the original sheet of glue is stable, and the interval control time can be manually controlled and set), the temperature sensor 5010 detects the temperature of the glue again. If it is still lower than the standard requirement range, the processing process is continued according to the above logic closed loop; If it is higher than the standard requirement range, the controller transmits a signal to the frequency converter, and the frequency converter controls the regulating motor 3014. The regulating motor 3014 drives the rotary plate 3011 to rotate along the rotary plate slide 3013 in the direction of reducing the opening of the heating roller exhaust hole 3010. The angle sensor 3015 measures the rotation angle. After reaching the rotation angle set by the control, the angle sensor 3015 transmits the angle measurement value to the controller. The controller transmits a signal to the frequency converter, and the frequency converter controls the regulating motor 3014 to stop running. The heat exchange efficiency is reduced, thereby achieving the effect of reducing the temperature of the rubber material. The rotation angle of the controller rotating the partition each time can be manually set. The specific operation plan is as follows: When 39℃<detection temperature T1≤44℃, adopt scheme 5, that is, reduce the angle of the existing rotating plate 3011 by 3 degrees (for example, the existing partition angle is 20 degrees, which is reduced to 17 degrees); When 44℃<detection temperature T1≤49℃, adopt scheme 6, that is, reduce the angle of the existing rotating plate 3011 by 5 degrees (for example, the existing partition angle is 20 degrees, which is reduced to 15 degrees); When the detected temperature T1>49°C, adopt scheme 7, that is, reduce the angle of the existing rotating plate 3011 by 7 degrees (for example, the existing partition angle is 20 degrees, which is reduced to 13 degrees); 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 sensor 5010 detects the temperature of the glue again. If it is still higher than the standard requirement range, the processing process will continue according to the above logic closed loop; When the controller sets the temperature range, it will refer to the detection value of the temperature sensor 5011 to fine-tune the gas heating temperature of the primary heating pretreatment component 301, so as to flexibly adapt to the pretreatment requirements of rubber materials at different temperatures; The temperature control component achieves precise control of the heating temperature through the combination of temperature sensors and controllers, ensuring the heating quality and stability of the rubber. Through different operating schemes, the heating temperature can be adjusted according to actual needs to adapt to the pretreatment requirements of rubbers at different temperatures. The fine-tuning mechanism makes the system more flexible and able to cope with pretreatment requirements in different environments.
