DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 , an internal mixer for producing rubber cups, comprising a base 1 and two power devices 2 symmetrically mounted on the top surface of the base 1, a shell 13 is also provided on the top surface of the base 1, the shell 13 is located between the two power devices 2, a rotating rod 15 is provided at the output end of the two power devices 2, a stirring rod is provided in the shell 13, the ends of the two rotating rods 15 are rotated to penetrate into the shell 13 and are respectively fixed to the two ends of the stirring rod, a lifting device 4 is provided on one side of the base 1, a pressure block 6 is slidably provided on the lifting device 4, a first motor 5 is provided on the top surface of the lifting device 4, the pressure block 6 corresponds to the opening at the upper end of the shell 13, and also includes a temperature control mechanism arranged on the outer side of the shell 13;

[0022] By setting the temperature control mechanism, in actual use, the outer wall of the shell 13 is wrapped with the temperature control mechanism, and the temperature control mechanism can quickly absorb the heat on the shell 13, so as to achieve the purpose of rapid cooling, and the cooling effect is significant.

[0023] Specifically, referring to 1-5, it is worth noting that the temperature control mechanism includes a refrigeration shell 3 wrapped around the outside of the shell 13, and a refrigeration tank 10 and a liquid exchange tank 9 are respectively arranged on both sides of the lifting device 4. A hose is connected and fixed between the delivery end of the liquid exchange tank 9 and the refrigeration tank 10. A spiral channel 12 is provided inside the refrigeration shell 3, and both ends of the channel 12 are connected to the outside. Two connecting blocks 16 are fixed on the outer wall of the refrigeration shell 3, and the two connecting blocks 16 are respectively connected to the two ends of the channel 12, and the ends of the two connecting blocks 16 away from the refrigeration shell 3 are connected and fixed with a connecting pipe 11, one of the connecting pipes 11 is connected and fixed to the liquid exchange tank 9, and the other connecting pipe 11 is connected and fixed to the water outlet end of the refrigeration tank 10, and the refrigeration tank 10 has a refrigeration plate built in;

[0024] When in use, the refrigeration shell 3 is wrapped around the outside of the shell 13, and the stirring rod in the shell 13 rotates relatively. The convex ridges on the stirring rod make the rubber material move along the axial direction of the rotor. As the rotation speed of the rotating rod 15 increases, the temperature in the shell 13 begins to rise. When the temperature rises to a certain level, the liquid exchange tank 9 and the refrigeration tank 10 are started, so that the water pump in the liquid exchange tank 9 starts to extract the liquid in the channel 12, so that the liquid in the refrigeration tank 10 that has been refrigerated by the refrigeration plate flows from the water outlet end into the connecting pipe 11 and enters the channel 12. After the refrigerated liquid enters the channel 12, it absorbs the temperature of the shell 13 and is sucked into the liquid exchange tank 9, and finally is sent back to the refrigeration tank 10 through the hose, thereby completing a cycle. The setting of the connecting pipe 11 and the connecting block 16 can ensure that the liquid exchange tank 9 and the refrigeration tank 10 can be smoothly connected to the refrigeration shell 3. The flow rate of the liquid can be controlled by controlling the rotation speed of the water pump in the liquid exchange tank 9 to achieve the purpose of controlling the internal temperature of the shell 13, thereby solving the problem of high temperature during operation of the internal mixer and over-refining or scorching of the rubber material.

[0025] In actual use, the rubber in the shell 13 is discharged from the feed port at the upper end of the shell 13 by turning over the shell 13. Since a temperature control mechanism is arranged on the outer side of the shell 13, and the temperature control mechanism transports liquid through the connecting tube 11, the connecting tube 11 is easy to fall off and be damaged when turning over, resulting in that the shell 13 cannot be turned over to discharge the rubber, and now a new discharge method is needed;

[0026] To solve the above problems, refer to Figure 1-4 As shown, it is worth noting that the base 1 has a groove corresponding to the bottom opening of the shell 13, and a receiving hopper 7 is provided in the groove. An isolation plate 8 with a cavity inside is provided between the base 1 and the shell 13. The isolation plate 8 has drop openings on both upper and lower end surfaces. The two drop openings are respectively connected to the shell 13 and the groove, and a blocking component is provided on the inner side of the isolation plate 8;

[0027] By setting the blocking component, the blocking component is in a closed state when feeding starts in the shell 13, so that stirring work can be carried out normally in the shell 13. When stirring is completed, the blocking component is opened to allow the rubber material to fall from the discharge port at the bottom of the shell 13, and the rubber material falls into the receiving hopper 7 through the isolation plate 8, realizing another discharge method of the rubber material and solving the problem that the shell 13 cannot be discharged by turning over. The rubber material is discharged from the bottom of the shell 13 and enters the receiving hopper 7 to enter the next process, thereby improving the working efficiency of the internal mixer.

[0028] Specifically, referring to Figure 2-3, it is worth noting that the blocking component includes two baffles 14 slidably arranged inside the isolation plate 8, and the two baffles 14 are provided with a power assembly on the side away from each other;

[0029] The power assembly includes a driving motor 17 installed in the isolation plate 8 and a screw 18 fixed to the output end of the driving motor 17, and the end of the screw 18 is threadedly penetrated into the inner wall of the baffle 14;

[0030] Through the setting of the power component and the baffle 14, when in use, when the rubber material is stirred in the shell 13, the two baffles 14 are against each other. When the stirring of the rubber material in the shell 13 is completed, the drive motor 17 is started to drive the screw 18 to rotate. The rotation of the screw 18 drives the baffle 14 to shrink and move in the direction of the drive motor 17. The baffle 14 is moved out from the through hole of the isolation plate 8, so that the rubber material in the shell 13 falls into the receiving hopper 7. At this time, the rotating rod 15 can be opened, and the rotation of the stirring rod can assist the rubber material to fall off from the shell 13. The power component provides the baffle 14 with power to move in the isolation plate 8. The baffle 14 can be opened and closed well, and cooperates with the shell 13 to complete the refining of the rubber material.

In the introduction, specific preferred embodiments are used to illustrate the principles and implementation methods of the utility model. These embodiments are only used to help understand the principles and core ideas of the utility model. It should be pointed out that for ordinary technicians in this field, without departing from the design ideas of the utility model, the implementation plans in the above embodiments can be further combined or replaced, and the utility model can be improved and modified in a number of ways. These improvements and modifications also fall within the scope of protection of the claims of the utility model.
