[0063] The power component includes a power motor 502. The power motor 502 is fixedly connected to the secondary heating pretreatment component box body 500. The output end of the power motor 502 is connected with an input shaft 5020. A switching gear 5021 is slidably keyed on the input shaft 5020.

[0067] 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 box body 500 of the secondary heating pretreatment assembly through the feed inlet 5000. Then, the power motor 502 is started to drive the input shaft 5020 to rotate reciprocally, driving the material leveling and stirring paddle 504 to rotate and stir the rubber material 100. At the same time, the switching gear 5021 is linked to drive the extrusion piston 5030 to push and pull reciprocally. When the extrusion piston 5030 moves to the right, the hot air in the heat supply assembly 300 is drawn 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 onto the rubber material 100 through the heat discharge plate 5033 to perform secondary heating pretreatment on the rubber material 100. During this process, the angle of the heat discharge plate 5033 can be adjusted by the telescopic movement of the push-pull cylinder 5035, thereby avoiding uneven heating.

A transition wheel 5042 is rotatably connected in the installation cavity 5022. A winding wire 5012 is wound around the winding wheel 5041. The winding wire 5012 is connected to the installation slider 5045 after passing over the transition wheel 5042. A U-shaped rod member 5046 is fixedly connected to the installation slider 5045. One end of the U-shaped rod member 5046 away from the installation slider 5045 is rotatably connected with a swing gear 5047.

One end of the pendulum connecting rod 5049 away from the position adjusting cylinder 5048 is rotatably connected with a pendulum 505.

[0070] The working principle and beneficial effects of the above technical solution are as follows: During operation, the switching cylinder 5023 drives the switching gear 5021 to mesh with the first meshing gear 5040. The power motor 502 drives the input shaft 5020 and the switching gear 5021 to rotate. The switching gear 5021 drives the first meshing gear 5040 to rotate, and the first meshing gear 5040 drives the winding wheel 5041 to reciprocate. The winding wheel 5041 drives the winding 5012 to reciprocally pull the installation slider 5045 to move left and right. During the left and right movement of the installation slider 5045, it pulls the extrusion piston 5030 to reciprocate, realizing the extrusion of hot air. At the same time, the left and right movement of the installation slider 5045 drives the U-shaped rod member 5046 to move left and right. Since the swing gear 5047 meshes with the linkage rack 5044, during the left and right movement of the U-shaped rod member 5046, it drives the swing gear 5047 to roll along the linkage rack 5044, thereby realizing the left and right swing of the pendulum connecting rod 5049 to hammer the rubber material 100. During this process, the telescopic movement of the position adjustment cylinder 5048 can change the spatial position of the pendulum 505, realizing the all-round hammering of the rubber material 100;

[0071] Through the design of components such as the material leveling component, the first slide rail 5043, the linkage rack 5044, and the installation slider 5045, the uniform stirring and hammering of the rubber material are realized, further improving the quality of the heating pretreatment.

[0072] Example 8

[0073] On the basis of Example 1, it further includes a temperature control component. The temperature control component includes a first temperature sensor 5011, a second temperature sensor 5010, and a controller. The controller is electrically connected to the first temperature sensor 5011, the second temperature sensor 5010, and the primary heating pretreatment component 301.

[0074] The working principle and beneficial effects of the above technical solution are as follows: Specifically, the second temperature sensor 5010 detects the temperature of the rubber material 100, and the detected temperature is sent to the controller as an input signal to determine which temperature range it is in, and then determine the corresponding operation mechanism. Through the actual detected temperature T1, determine the corresponding operation plan (the corresponding operating temperature range and the corresponding operation plan mechanism, etc. can be set and modified manually to meet the actual production needs). For example:

[0075] When 34°C ≤ detected temperature T1 ≤ 39°C, that is, within the standard temperature requirement range, adopt Plan 4, that is, maintain the existing position state of the rotating partition;

[0076] If it is below the standard requirement range, then the controller transmits a signal to the frequency converter, and the frequency converter controls and adjusts the motor 3014. The adjusting motor 3014 drives the rotating plate 3011 to rotate along the rotating plate slideway 3013 in the direction of increasing the opening of the heating roller exhaust hole 3010. The angle sensor 3015 measures the rotation angle. After reaching the controlled set rotation angle, 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 and adjusts the motor 3014 to stop running. The heat exchange efficiency is improved, thereby achieving the effect of increasing the temperature of the rubber compound. The rotation angle of the rotating plate 3011 by the controller can be set manually. The specific operation plan is as follows:

[0077] When 29°C ≤ detected temperature T1 < 34°C, adopt Plan 3, that is, increase by 3 degrees on the basis of the existing angle of the rotating plate 3011 (for example, if the existing partition angle is 20 degrees, increase to 23 degrees);

[0078] When 24°C ≤ detected temperature T1 < 29°C, adopt Plan 2, that is, increase by 5 degrees on the basis of the existing angle of the rotating plate 3011 (for example, if the existing partition angle is 20 degrees, increase to 25 degrees);

[0079] When the detected temperature T1 < 24°C, adopt Plan 1, that is, increase by 7 degrees on the basis of the existing angle of the rotating plate 3011 (for example, if the existing partition angle is 20 degrees, increase to 27 degrees);

[0080] After a certain interval, that is, after the temperature of the original sheet rubber reaches stability (determine whether the temperature of the original sheet rubber is stable by the temperature difference between adjacent detection times of the temperature sensor two 5010, and the interval control time can be set manually), the temperature sensor two 5010 detects the temperature of the rubber compound again. If it is still below the standard requirement range, the above logic loop continues to be processed;

[0081] If it is above the standard requirement range, then the controller transmits a signal to the frequency converter, and the frequency converter controls and adjusts the motor 3014. The adjusting motor 3014 drives the rotating plate 3011 to rotate along the rotating plate slideway 3013 in the direction of decreasing the opening of the heating roller exhaust hole 3010. The angle sensor 3015 measures the rotation angle. After reaching the controlled set rotation angle, 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 and adjusts the motor 3014 to stop running. The heat exchange efficiency is reduced, thereby achieving the effect of reducing the temperature of the rubber compound. The rotation angle of the partition by the controller can be set manually. The specific operation plan is as follows:

[0082] When 39°C < detected temperature T1 ≤ 44°C, adopt Plan 5, that is, reduce by 3 degrees on the basis of the existing angle of the rotating plate 3011 (for example, if the existing partition angle is 20 degrees, reduce to 17 degrees);

[0083] When 44°C < detected temperature T1 ≤ 49°C, adopt Solution 6, that is, reduce the angle of the existing rotary plate 3011 by 5 degrees (for example, if the existing baffle angle is 20 degrees, reduce it to 15 degrees);

[0084] When the detected temperature T1 > 49°C, adopt Solution 7, that is, reduce the angle of the existing rotary plate 3011 by 7 degrees (for example, if the existing baffle angle is 20 degrees, reduce it to 13 degrees);

[0085] After a certain interval, that is, after the temperature of the original sheet glue reaches stability (the interval control time can be manually set), the temperature sensor two 5010 detects the temperature of the glue again. If it is still higher than the standard required range, the processing process continues in a closed loop according to the above logic;

[0086] During the process of setting the temperature range in the controller, the detected value of the temperature sensor one 5011 is referred to for fine-tuning the gas heating temperature of the primary heating pretreatment component 301, so as to flexibly adapt to the pretreatment requirements of different temperature glues;

[0087] Through the combination of the temperature sensor and the controller, the temperature control component realizes precise control of the heating temperature, ensuring the heating quality and stability of the glue. Through different operation solutions, the heating temperature can be adjusted according to actual needs to adapt to the pretreatment requirements of different temperature glues. The fine-tuning mechanism makes the system more flexible and able to meet the pretreatment requirements in different environments.

[0088] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention is also intended to include these changes and modifications.
