[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under a very small external force.

However, during the rubber mixing process, the rubber in the mixing process needs to be heated. The temperature and time of rubber mixing determine the mixing effect. In view of this, we propose a feeding mechanism for rubber mixing, which can exchange heat with the discharge during the feeding process to achieve energy saving. Utility Model Content

[0026] See also Figure 1-4 ,The utility model provides a technical solution:

[0027] A rubber mixing feeding mechanism includes a feeding mechanism 2 arranged on a mixer body 1. The mixer body 1 is also provided with a discharging mechanism 3. The feeding mechanism 2 includes a conveyor belt 201. The middle of the conveyor belt 201 passes through the discharging mechanism 3. The conveyor belt 201 carries raw materials and performs heat exchange with products discharged by the discharging mechanism 3.

[0028] In the utility model, by arranging the feeding mechanism 2 inside the discharging mechanism 3, heat exchange can be performed during discharging, so that the discharged mixed rubber and the rubber to be mixed are preheated, thus saving resources and reducing the use of heat energy.

[0029] Furthermore, the discharging mechanism 3 includes a discharging funnel 301 which is arranged through the lower end of the mixer body 1, the discharging funnel 301 is connected to a transmission auger 302, the upper end of the transmission auger 302 is connected to a discharge chute 303, the discharge chute 303 is located above the mixer body 1, and the discharge chute 303 is arranged at an angle.

[0030] In actual use, after the mixing is completed, the rubber enters the transmission auger 302 through the discharge funnel 301 , and is then re-transmitted to the top of the mixer body 1 through the transmission auger 302 , and enters the interior of the transmission shell 304 through the discharge chute 303 .

[0031] Furthermore, the discharging mechanism 3 also includes a transmission shell 304 arranged at the upper end of the mixer body 1, a square through hole is opened in the middle of the transmission shell 304, a circular shell 305 is arranged inside the lower end of the transmission shell 304, the circular shell 305 is through-connected with the square through hole, a V-shaped plate 306 is arranged on the upper part of the transmission shell 304, and two discharge troughs 307 are through-connected at both ends of the lower part of the transmission shell 304, and the two discharge troughs 307 are in an eight-shaped structure as a whole.

[0032] It should be noted that after the mixed rubber material passes through the discharge chute 303 and enters the interior of the transmission shell 304, it is separated by the V-shaped plate 306 and enters the two ends of the transmission shell 304, and then enters between the outside of the circular shell 305 and the inner wall of the transmission shell 304 from the two ends of the transmission shell 304. At this time, the rubber raw material on the conveyor belt 201 inside the circular shell 305 is preheated to increase the temperature of the raw material, while reducing the temperature of the mixed rubber, thereby saving electricity.

[0033] Furthermore, the side wall of the circular shell 305 is made of metal. Since the circular shell 305 is made of metal, it serves as an excellent conductor of heat, thereby improving the heat exchange effect.

[0034] Furthermore, the feeding mechanism 2 also includes a feeding funnel 202 , the lower end of the feeding funnel 202 is connected to the lower end of the circular shell 305 , and the feeding funnel 202 is located between the two discharge troughs 307 .

[0035] In actual use, the rubber raw material falls onto the conveyor belt 201 through the feed hopper 202, enters the inner part of the circular shell 305 after being transported by the conveyor belt 201, continues to be transported by the conveyor belt 201 after heat exchange, and then enters the inner part of the mixer body 1 through the square through hole.

[0036] It should be added that Figure 4 As shown, the arrows point to the feeding direction and the discharging direction respectively.

[0037] Furthermore, the lower end of the conveyor belt 201 is located inside the lower end of the feed funnel 202, and a drive roller 203 is connected between the lower end of the feed funnel 202, the inside of the circular shell 305 and the inner wall of the square through hole. The conveyor belt 201 is movably connected to the drive roller 203, and a drive motor 204 is provided on the feed funnel 202. The output end of the drive motor 204 is connected to the end of one of the drive rollers 203.

[0038] In actual use, the driving motor 204 drives the driving roller 203 to rotate, and the driving roller 203 drives the conveyor belt 201 to convey the rubber raw materials forward. It should be added that during the first mixing process of the equipment, no heat exchange is performed. Afterwards, the materials mixed in the previous batch are heat exchanged with the materials to be mixed in the next batch, thereby saving electricity.

[0039] Working principle: the driving motor 204 drives the driving roller 203 to rotate, and the driving roller 203 drives the conveyor belt 201 to convey the rubber raw material forward. The raw material enters the interior of the mixer body 1 through the square through hole. At the same time, the rubber material that has been mixed in the previous batch passes through the discharge chute 303 and enters the interior of the transmission shell 304. It is separated by the V-shaped plate 306 and enters the two ends of the transmission shell 304. From the two ends of the transmission shell 304, it enters between the outside of the circular shell 305 and the inner wall of the transmission shell 304. At this time, the rubber raw material on the conveyor belt 201 inside the circular shell 305 is preheated to increase the temperature of the raw material and reduce the temperature of the mixed rubber at the same time, so as to save electric energy. The mixed material between the outside of the circular shell 305 and the inner wall of the transmission shell 304 is discharged through the discharge chute 307.
