Conventional methods employ heating rings on the sidewalls of the conveying pipes. These rings heat the pipe walls, which in turn heat the rubber within them. However, the portion of the rubber located at the central axis of the pipe, being further away from the pipe wall, receives insufficient heat, resulting in poor mixing quality. Utility Model Content

[0009] Furthermore, the heating box is filled with a filling liquid, and the heating layer heats the delivery pipe specifically through the filling liquid. The inner wall of the heating layer is provided with blades for stirring the filling liquid in the heating box.

[0010] Furthermore, there are two blades, one of which is installed at the bottom of the inner wall of the heating layer on the side close to the input end of the conveying pipe, and the other is installed at the top of the inner wall of the heating layer on the side close to the output end of the conveying pipe.

The three groups of heating boxes 5 are all provided with conveying pipes 12, wherein: in the first group of heating boxes 500, the input end of the conveying pipe 12 passes through the outside of the first group of heating boxes 500 and is connected to the output end of the mixing mechanism 3. A control valve 4 is provided at the connection point. The output end of the conveying pipe 12 passes through the outside of the first group of heating boxes 500 and is connected to the input end of the conveying pipe 12 in the second group of heating boxes 501. The output end of the conveying pipe 12 in the second group of heating boxes 501 passes through the outside of the second group of heating boxes 501 and is connected to the input end of the conveying pipe 12 in the third group of heating boxes 502. The output end of the conveying pipe 12 of the third group of heating boxes 502 passes through the outside of the third group of heating boxes 502 and is provided with an outlet valve 6.

[0019] like Figure 1 The bottom is the base plate 10, and the vacuum suction machine 2 is mounted on the base plate 10 by the support rod 7. Specifically, the connecting plate 71 at the bottom of the support rod 7 is fixedly connected to the base plate 10, and the fixing seat 72 at the top of the support rod 7 is fixedly connected to the vacuum suction machine 2. The feeding pipe 1 is installed at the bottom of the vacuum suction machine 2. The mixing mechanism 3 is supported on the base plate 10 by the support column 8, and the heating box 5 is directly mounted on the base plate 10. Each heating box 5 is as shown in FIG. Figure 2 , an insulation layer 51 is installed inside, a heating layer 52 for heating the inside of the box is installed inside the insulation layer 51, a heating tube 53 with adjustable temperature is provided inside the heating layer 52, the heating box 5 is filled with filling liquid, and the heating layer 52 specifically heats the delivery pipe 12 through the filling liquid. The top of the inner wall of the heating layer 52 close to the input end of the delivery pipe 12 and the bottom of the inner wall of the heating layer 52 close to the output end of the delivery pipe 12 are each installed with a blade 9 for stirring the filling liquid in the heating box 5. The blade 9 stirs the filling liquid in the heating box 5 to make the temperature of the filling liquid in the box uniform, thereby avoiding excessive temperature difference between the input end and the output end of the rubber material in the delivery pipe 12 of the heating box 5. Figure 3The protective shell 100 is installed on the outside of the three groups of heating boxes 5 to protect the three groups of heating boxes 5.

The signal of the adjustment control button 102 is transmitted to the controller (omitted in the figure). The controller controls the heating of the heating tube 53. The three groups of heating boxes 5 are at different temperatures. Among them, the temperature of the first group of heating boxes 500 is the lowest, the temperature of the second group of heating boxes 501 is moderate, and the temperature of the third group of heating boxes 502 is the highest, which meets the heating requirements of the rubber at different stages.

The rubber material is turned to the top, passes through the corner, and is transported downward again by its own weight; the heating box 5 heats the wall of the conveying pipe 12, and the wall heats the rubber material in the conveying pipe 12. After the rubber material is heated, it is discharged from the outlet valve 6. The input and output ends of the conveying pipe 12 are both flat tubes, as shown Figure 4 As shown, the distance d between the central axis 123 and the flat side tube wall 121 is relatively close, and the central axis 123 of the input end and the output end of the conveying tube 12 is sufficiently heated, and the rubber material is fully heated at the central axis 123 of the input end and the output end of the conveying tube 12; in the circular tube, the rubber material is driven upward by the screw 121, and the rubber material is turned over during the upward transportation process, and the rubber material is heated evenly, thereby improving the rubber mixing quality and production efficiency.
