Technical Field

[0001] The utility model relates to the technical field of rubber internal mixers, in particular to a rubber processing internal mixer. Background Art

[0002] A closed rubber mixer, also known as an internal mixer or kneader, is primarily used for plasticating and mixing rubber. An internal mixer is a device that features a pair of rotors of a specific shape that rotate relative to each other, intermittently plasticating and mixing polymer materials in a closed environment with adjustable temperature and pressure.

[0003] For example, a rubber internal mixer for rubber processing in the prior art (publication number: CN219806329U) drives the fan blades into the internal mixer body through an electric telescopic rod, and the first rotating shaft drives the fan blades to rotate to dissipate heat inside the internal mixer body. Ice water is poured into the water inlet pipe, and the rotation of the threaded rod drives the two sliders to synchronously drive the box body to move toward the internal mixer body. The box body and the internal mixer body are in contact, and the second rotating shaft drives the spiral blades to rotate, thereby stirring and disturbing the ice water, thereby achieving heat dissipation outside the internal mixer body.

[0004] However, a common internal mixer body is provided with a spiral rod, so when the fan blades enter the internal mixer body, they will interfere with the spiral stirring rod therein, causing the fan blades to be unable to fully enter the internal mixer body, thereby affecting the internal heat dissipation efficiency.

[0012] Furthermore: the water inlet of the water pump extends to the inner bottom of the water tank, and the other end of the connecting pipe is located above the water tank.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, after the temperature of water in the water tank is adjusted to a low temperature state, the rubber processed inside the mixer body is completely discharged under the squeezing action of the spiral stirring blade, and then the low-temperature water is sent into the chamber along the water inlet cavity by a water pump, and flows to the water outlet pipe in the chamber, and then flows back to the water tank through the water outlet pipe to be adjusted to an appropriate temperature, and then circulated into the chamber for use.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-4As shown, a rubber processing internal mixer includes an internal mixer body 5 and an internal spiral stirring blade 8. The internal mixer body 5 is fixedly connected to a support 1. Specifically, the rubber feed port of the support 1 is located at the top position of the surface of the internal mixer body 5. The position of the spiral stirring blade 8 on the support 1 is fixedly connected to a water tank 4 for controlling the water temperature. Two heating wires and a condenser tube for heating and cooling are fixedly connected in the water tank 4. Specifically, the heating wire and the condenser tube can be selected from the common electric heating wire and the compressor condenser tube on the market. Both are placed in the water tank 4. The water in the water tank 4 can be heated by the heating wire to form hot water. The hot water When passing through the chamber 9, the surface of the spiral stirring blade 8 and the interior of the mixer body 5 can be quickly heated up, rubber can be added to soften it, or a condenser can be used to reduce the water in the water tank 4 to cold water or ice water. After the rubber is processed and discharged, when passing through the chamber 9, the temperature of the spiral stirring blade 8 and the interior of the mixer body 5 can be reduced to protect the internal parts of the mixer body 5. A water inlet chamber 12 is provided at one end of the rod portion of the spiral stirring blade 8, and a chamber 9 for water flow to pass through is provided inside the blade portion. One end of the chamber 9 is connected to the water inlet chamber 12, and the other end is connected to a water outlet pipe 10. The surface of the water outlet pipe 10 passes through the spiral stirring blade. 8 blades, and the surface is fixedly connected with a scraper 15 for cleaning the inner surface of the mixer body 5. One end of the outlet pipe 10 passes through the water inlet chamber 12 and is extended through one end of the spiral stirring blade 8 rod. A water pump 11 for connecting the water inlet chamber 12 and the inside of the water tank 4 is fixedly connected to the support 1, and a connecting pipe 14 is also connected between the water tank 4 and the port of the outlet pipe 10. Specifically, the water pump 11 selects a water pump of a commonly used model and size on the market. When processing rubber, the water pump 11 draws hot water from the water tank 4 into the water inlet chamber 12, and then enters the chamber 9 along one end of the chamber 9, and in the chamber 9 until it passes through the inside of the spiral stirring blade 8. After the spiral stirring blade 8 is heated to a certain temperature, additional heat is applied to the rubber during the stirring and extruding process, so that the rubber is quickly softened. After the heat of the hot water entering the chamber 9 is evaporated, it will re-enter the water tank 4 along the water outlet pipe 10 to be heated again and reused. Similarly, when the water injected into the chamber 9 is ice water, it can absorb the heat inside the spiral stirring blade 8 and the mixer body 5, and the ice water that has absorbed the heat will re-enter the water tank 4 along the water outlet pipe 10 to be cooled again and reused, thereby reducing the consumption of water resources.

[0024] like Figure 1As shown, the support 1 is fixedly connected with an electric telescopic rod 2, and the telescopic end of the electric telescopic rod 2 is fixedly connected with a conducting pipe 3 for rubber circulation reflux. Specifically, the conducting pipe 3 can push the squeezed rubber along one end of the conducting pipe 3 to the other end during the process of the spiral stirring blade 8 pushing and squeezing the rubber, and then re-enter the mixing machine body 5, and move again under the rotation and pushing action of the spiral stirring blade 8, that is, to realize the circulation flow of the rubber in the mixing machine body 6. The bottom positions of both ends of the mixing machine body 5 are provided with openings corresponding to the ports of the conducting pipe 3, and the outer wall of the conducting pipe 3 is fixedly connected with a connecting piece 6 sleeved on the support 1. Specifically, the connecting piece 6 ensures that the conducting pipe 3 can only rise along the surface of the support 1 The guide tube 3 is lifted up and down, and is lifted up and down under the extension and contraction action of the electric telescopic rod 2. By lifting and lowering the electric telescopic rod 2, the guide tube 3 can be lifted up to fit with the opening of the mixing body 5 to ensure that the rubber is circulated during the processing, or the guide tube 3 can be lowered to the opening where it is separated from the mixing body 5, so that the processed rubber is squeezed out along the opening at one end of the mixing body 5 under the pushing and squeezing action of the spiral stirring blade 8. In addition, the guide tube 3 can be selected to be spliced ​​from two parts, one half is fixed to the electric telescopic rod 2 and the connecting piece 6, and the other half is detachable, and the two halves are spliced ​​together by bolts or clamps. After the rubber processing is completed, the guide tube 3 can be disassembled to remove the residual rubber inside.

[0025] like Figure 4 As shown, a rotary joint 7 is connected between the water outlet of the water pump 11 and the cavity mouth of the water inlet chamber 12. Specifically, the rotary joint 7 is an existing product, that is, one end can rotate relative to the other end without leaking. One end of the mixer body 5 is fixedly connected to a connecting shell 13 for covering the water outlet pipe 10. The connecting shell 13 is fixedly connected to the outer wall of the rotary joint 7 at the water outlet of the water pump 11 and is communicated with one end of the connecting pipe 14. Specifically, the rotary joint 7 is used to ensure that the rotation of the spiral stirring blade 8 can drive one half of the rotary joint 7 to rotate relative to the other half. The other half of the rotary joint 7 is fixed to the water outlet end of the water pump 11 and is fixed to the connecting shell 13. Therefore, It can prevent the connecting shell 13 from leaking, and at the same time ensure that the spiral stirring blade 8 can drive the port of the water outlet pipe 10 to rotate in the connecting shell 13, and use the connecting shell 13 to collect water flowing out of the water outlet pipe 10, and use the connecting pipe 14 to return it to the water tank 4. The water inlet of the water pump 11 extends to the inner bottom of the water tank 4, and the other end of the connecting pipe 14 is located above the water tank 4. Specifically, it is ensured that the water pump 11 pumps water from the bottom of the water tank 4, and the reflux water is located at the inner top of the water tank 4. When the reflux water reaches the water inlet of the water pump 11, a certain distance and time difference is generated, ensuring that the reflux water can be adjusted to an appropriate temperature by the heating pipe or condenser in the water tank 4.

[0026] Working principle: use the condenser to cool the water inside the water tank 4, the electric telescopic rod 2 contracts, and the guide tube 3 is pulled to be offset from the side opening of the mixer body 5. Then, the spiral stirring blade 8 is driven to start by installing the motor to realize the extrusion and discharge of the processed rubber. The cold water in the water tank 4 is sent into the water inlet chamber 12 through the rotary joint 7 by the water pump 11, and then sent into the chamber 9 along the water inlet chamber 12. During the flow process, the surface of the spiral stirring blade 8 absorbs heat, and then the heat inside the mixer body 5 is absorbed to achieve cooling. The cold water that has absorbed heat is converted into hot water. The hot water re-enters the water tank 4 through the outlet pipe 10 and the connecting pipe 14, realizing the hot water to be converted into cold water again, and then re-enters the chamber under the action of the water pump 11.

[0027] The wiring diagram of the electric telescopic rod 2 and the water pump 11 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the electric telescopic rod 2 and the water pump 11 are not explained in detail.
