[0012] The present invention is further configured such that the preheating plate is heated by an internal electric heating plate.
[0013] In summary, this utility model has the following beneficial effects: it can introduce silicone rubber material into the shell and preheat the silicone rubber by rotating two preheating plates driven by a motor. During preheating, the silicone rubber can be directly heated by the two preheating plates, which can greatly improve the preheating efficiency and reduce the preheating time.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] A preheating device for processing silicone rubber products, such as Figures 1-4As shown, the device includes a housing 1, inside which several preheating plates 2 are rotatably connected. A motor 3 is fixedly connected to the housing 1, and the output end of the motor 3 is fixedly connected to one of the preheating plates 2 on the upper side of the lowest preheating plate 2. A transmission roller 4 is fixedly connected to the preheating plate 2, and the several transmission rollers 4 are connected to each other by a transmission belt 5. When it is necessary to preheat the silicone rubber material, the housing 1 can be installed at the inlet of the next process device, and then the motor 3 and the preheating plate 2 can be turned on. The motor 3 will drive the preheating plate 2 fixedly connected to it to rotate, and then this preheating plate 2 will drive the other preheating plates 2 to rotate through the transmission belt 5. When one of the preheating plates 2 is connected to the upper side of the lowest preheating plate 2, the transmission roller 4 is fixedly connected to the preheating plate 2. When the ground is vertical, the adjacent preheating plate 2 will be parallel to the ground, which can prevent the silicone rubber material from flowing out of the outer shell 1 before it has come into contact with all the preheating plates 2. Then, the silicone rubber material is introduced into the outer shell 1. The silicone rubber material will first come into contact with the topmost preheating plate 2 and be heated and softened by this preheating plate 2. Then it will flow down between this preheating plate 2 and the outer shell 1, flow to the next preheating plate 2, come into contact with the next preheating plate 2, and be heated and softened again. After being heated and softened by the bottommost preheating plate 2, it will flow out of the outer shell 1 and flow into the next process device. In this way, the preheating efficiency can be greatly improved and the preheating time can be reduced.
[0018] like Figures 1-3 As shown, a mounting base 6 is fixedly connected to the outer shell 1, and several protrusions 7 are fixedly connected to the mounting base 6. A positioning plate 8 is fixedly connected to the end of the lowermost preheating plate 2 away from the transmission roller 4. A spring telescopic rod 9 is fixedly connected to the positioning plate 8, and a hemispherical block 10 is fixedly connected to the telescopic end of the spring telescopic rod 9. The hemispherical block 10 makes the spring telescopic rod 9 contact with the protrusions 7 more smoothly. When the lowermost preheating plate 2 is driven by the transmission belt 5, it will simultaneously drive the positioning plate 8, the spring telescopic rod 9, and the hemispherical block 10 to rotate. Then the hemispherical block 10 will contact several protrusions 7. When the hemispherical block 10 contacts one of its protrusions 7, the spring telescopic rod 9 will be in a retracted state. Then the spring telescopic rod 9 and the hemispherical block 10 continue to rotate, and the spring telescopic rod 9 will reset and drive the hemispherical block 10 to contact two adjacent protrusions 7. At this time, the hemispherical block 10 will collide with two adjacent protrusions 7, and the protrusions 7 and the mounting base 6 will vibrate. Finally, the vibration will be transmitted to the outer shell 1, which can assist in material feeding.
[0019] like Figure 2As shown, a guide ring 11 is fixedly connected between two adjacent preheating plates 2 in the outer shell 1. When the adjacent preheating plate 2 on the upper side of the guide ring 11 is in a vertical state, the adjacent preheating plate 2 on the upper side of the guide ring 11 is in contact with the guide ring 11. When the lowermost preheating plate 2 is in a vertical state, the lowermost preheating plate 2 is in contact with the inner bottom side of the outer shell 1. When the silicone rubber material comes into contact with the uppermost preheating plate 2, the first preheating will occur. Subsequently, as the uppermost preheating plate 2 rotates, the silicone rubber material will flow down from the gap between the guide ring 11 and the uppermost preheating plate 2. At this time, if the silicone rubber material is subjected to... As the topmost preheating plate 2 heats up, its viscosity decreases and its fluidity increases. This portion of silicone rubber material then flows down through the through-hole of the guide ring 11. Silicone rubber material whose viscosity has not decreased or has not met the standard will adhere to the guide ring 11 and flow down slowly. Subsequently, this portion of silicone rubber material will come into contact with the topmost preheating plate 2 again and be propelled by the topmost preheating plate 2, returning to the topmost preheating plate 2 for reheating. This makes the preheating more uniform. If some silicone rubber material whose viscosity has not decreased or has not met the standard flows down through the through-hole of the guide ring 11, it will also be preheated by the next preheating plate 2.
[0020] like Figure 4 As shown, the preheating plate 2 generates heat through the internal heating plate 12, which makes the reheating of the silicone rubber material by the preheating plate 2 more uniform.
[0021] Working principle: When preheating of silicone rubber material is required, the outer shell 1 can be installed at the inlet of the next process device. Then, the motor 3 and the preheating plate 2 are turned on. The motor 3 will drive the preheating plate 2, which is fixedly connected to it, to rotate. Subsequently, this preheating plate 2 will drive the other preheating plates 2 to rotate via the transmission belt 5. Then, the silicone rubber material is introduced into the outer shell 1. The silicone rubber material will first come into contact with the topmost preheating plate 2 and be heated and softened by this preheating plate 2 for the first preheating. Subsequently, as the topmost preheating plate 2 rotates, the silicone rubber material will flow down from the gap between the guide ring 11 and the topmost preheating plate 2. At this time, if the silicone rubber material has reduced viscosity and increased fluidity due to heating by the topmost preheating plate 2, this part... The silicone rubber material will flow down from the through hole of the guide ring 11. The silicone rubber material whose viscosity has not been reduced or has not met the standard will adhere to the guide ring 11 and flow down slowly. Then, this part of the silicone rubber material will come into contact with the topmost preheating plate 2 again and be pushed by the topmost preheating plate 2 to return to the topmost preheating plate 2 for reheating. This can make the preheating more uniform. If some silicone rubber material whose viscosity has not been reduced or has not met the standard flows down from the through hole of the guide ring 11, it will also be preheated by the next preheating plate 2 and heated and softened again. After being heated and softened by the bottommost preheating plate 2, it will flow out from the outer shell 1 and flow into the next process device. This can greatly improve the preheating efficiency and reduce the preheating time.

All technical solutions falling within the scope of this utility model's concept are protected.
