Description

Technical Field

[0001] This application relates to the field of internal mixer technology, and more specifically, to a constant temperature tilting internal mixer. Background Technology

[0002] Internal mixers are mainly used for plasticizing and mixing rubber. An internal mixer is a machine with a pair of rotors of a specific shape that rotate relative to each other, which intermittently plasticizes and mixes polymer materials in a closed state with adjustable temperature and pressure. It mainly consists of a mixing chamber, rotors, rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base.

[0003] When the internal mixer is working, the raw rubber and compounding agents are loaded into the mixing chamber from the feeding hopper. The material gate is closed, and the top bolt of the pressing device is pressed down. The two rotors in the mixing chamber rotate in opposite directions at different or the same speed. The loaded rubber compound is subjected to continuous stirring, folding and strong kneading between the rotors and between the rotors and the mixing chamber, which produces oxidative chain scission and increases plasticity. At the same time, the rubber compound is dispersed and uniformly mixed due to shearing action, thereby achieving the purpose of rubber mixing.

[0004] When rubber is mixed in the internal mixing chamber, the chamber needs to be at a suitable temperature—neither too high nor too low. Traditional internal mixers use a closed design, which makes heat difficult to dissipate. During subsequent processing, this heat accumulates, causing a rapid increase in temperature within the mixing chamber, leading to rapid rubber curing and affecting subsequent processing. Most modern internal mixers use dedicated temperature controllers equipped with heating, cooling water circulation, and temperature control devices, allowing for separate heating or cooling as needed. Initially, when the actual temperature is lower than the set temperature, the electric heater is energized and heating begins. Once the set temperature is reached, heating stops, and the system begins heat preservation. When the actual temperature exceeds the set temperature and cooling is required, the electric valve on the cooling water return line opens, discharging the overheated water from the system. Simultaneously, pressurized cooling water is added to the system to achieve a cooling effect. However, the requirements differ in different areas of the mixing chamber. For example, during operation, the area where the mixing chamber wall and rotor work together to shear the material experiences greater friction, which generates more heat and requires cooling. On the other hand, the area where the mixing chamber wall does not work with the rotor does not experience friction and therefore does not require cooling. In fact, to prevent the material from condensing due to low temperature in this area, it is necessary to raise the temperature. However, existing mixing machines have difficulty accurately controlling the temperature of different areas.

[0005] Therefore, a constant-temperature tilting internal mixer is needed to solve the above problems. Summary of the Invention

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a constant-temperature tilting internal mixer, comprising: a main body with a tilting internal mixing chamber, characterized in that: it further comprises: a rotor, rotatably disposed within the internal mixing chamber for material mixing; a covering shell, covering the outside of the internal mixing chamber, and a temperature control component disposed within the covering shell; a first temperature control pipe connected to a first temperature control water pipe; a second temperature control pipe connected to another second temperature control water pipe; and multiple heat conduction platforms evenly disposed on the outer wall of the internal mixing chamber; the temperature control component comprises: a first main pipe connected to the second temperature control pipe, with multiple first branch pipes arranged along the outer wall of the internal mixing chamber on the first main pipe; a second main pipe connected to the first temperature control pipe, with multiple second branch pipes arranged along the outer wall of the internal mixing chamber on the second main pipe, wherein one second branch pipe and one first branch pipe form a temperature control unit, and one temperature control unit cooperates with one heat conduction platform.

[0008] Furthermore, a heat conduction platform 1 is fixedly installed on the side of branch pipe 1 near the heat conduction platform, and a heat conduction platform 2 is fixedly installed on the side of branch pipe 2 near the heat conduction platform. There are gaps between heat conduction platform 1 and heat conduction platform 2 and the heat conduction platform. A temperature conduction component located in the gap is installed on the heat conduction platform.

[0009] Furthermore, the temperature-conducting assembly includes: step block one and step block two, with step block one located in the gap between heat-conducting platform one and heat-conducting platform two, and step block two located in the gap between heat-conducting platform two and heat-conducting platform two; a guide rod passing through step block one and step block two and slidingly engaging with step block one and step block two; an electric telescopic rod, with the working end of the electric telescopic rod fixedly connected to the guide rod; retaining rings fixed at both ends of the guide rod, with the two retaining rings respectively abutting against the opposite sides of step block one and step block two; and a spring disposed between the intermediate ring and step block one and between the intermediate ring and step block two.

[0010] Furthermore, a side panel is provided on the outer wall of the mixing chamber, and an electric telescopic rod is fixedly installed on the side panel.

[0011] Furthermore, a contact surface 1 is provided on the side of the heat-conducting platform 1 near the heat-conducting platform, and a contact surface 2 is provided on the side of the heat-conducting platform 2 near the heat-conducting platform. Both contact surfaces 1 and 2 are inclined in opposite directions. The heat-conducting platform has a heat-conducting surface 1 and a heat-conducting surface 2, with the heat-conducting surface 1 facing the contact surface 1 and the heat-conducting surface 2 facing the contact surface 2. Step 1 is located between the heat-conducting surface 1 and the contact surface 1, and step 2 is located between the heat-conducting surface 2 and the contact surface 2.

[0012] Furthermore, step one has a first surface that abuts against heat-conducting surface one and a second surface that abuts against contact surface one, and step two has a third surface that abuts against heat-conducting surface two and a fourth surface that abuts against contact surface two.

[0013] Furthermore, thermally conductive silicone is provided on the first, second, third, and fourth surfaces.

[0014] Furthermore, a temperature sensor is installed on the heat conduction platform to detect the temperature of the area.

[0015] Furthermore, the heat-conducting platform, ladder block one, ladder block two, heat-conducting platform one, and heat-conducting platform two are all made of heat-conducting materials.

[0016] The beneficial effects of this application are as follows: 1. A heat-conducting platform is set up. The heat-conducting platform has an arc-shaped structure and is arranged along the side wall. One branch pipe and one branch pipe form a temperature control unit. One temperature control unit works with one heat-conducting platform. One heat-conducting platform is set up with multiple segments.

Gaps exist between heat-conducting platforms 1 and 2 and the heat-conducting platform itself. Each section of the heat-conducting platform is equipped with a temperature-conducting component located within the gap. The heat is transferred from the heat-conducting platform to branch pipe 2 via the temperature-conducting component and heat-conducting platform 2, thereby cooling the area connected to the heat-conducting platform. Alternatively, the heat is transferred from branch pipe 1 to the heat-conducting platform via the temperature-conducting component and heat-conducting platform 1, allowing branch pipe 1 to heat the corresponding area, thus achieving accurate temperature control for different areas.

[0018] 3. By designing the system, when step block one and step block two move, it prevents slippage and friction on the first, second, third, and fourth surfaces, which could cause the thermal conductive silicone to fall off. At the same time, when the electric telescopic rod extends or retracts, it can also generate pressure between the thermal conductive silicone sheet and the contact surface, ensuring a good fit and improving the heat conduction effect.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0028] Reference Figure 1-5A constant-temperature tilting internal mixer includes a main body 10 and a mixing chamber 11. The mixing chamber 11 is tilted and mounted on the main body 10. Two rotors 111 are rotatably mounted inside the mixing chamber 11, and the two rotors 111 cooperate to mix the materials inside the mixing chamber 11. The mixing chamber 11 has a U-shaped frame structure with U-shaped side walls 117 and end walls at both ends. A cover shell 112 is installed on the outside of the side walls of the rotors 111 to provide some protection for the temperature control pipes. A temperature control assembly is also provided on the mixing chamber 11, which includes a temperature control pipe 113, a temperature control pipe 114, and a heat conduction platform 118. The temperature control pipe 113 can be connected to an external cooling water pump, and the temperature control pipe 114 can be connected to an external hot water circulation pump.

[0029] Temperature control pipe 114 is connected to main pipe 121 located inside the casing 112. Main pipe 121 has multiple sets of branch pipes 123. Temperature control pipe 113 is connected to main pipe 122 located inside the casing 12. Main pipe 122 has multiple sets of branch pipes 124. Branch pipes 123 and 124 are alternately arranged and correspond one-to-one. One end of each set of branch pipes 123 is connected to a return port 115, and one end of each set of branch pipes 124 is connected to a return port 116. It is easy to understand that water return is achieved through return ports 115 and 116, keeping the water flowing in branch pipes 123 and 124. It should be noted that heat insulation material can be installed between branch pipes 123 and 124 to prevent heat loss.

[0030] Multiple sets of heat-conducting platforms 118 are installed on the outer wall of the mixing chamber 11. Each heat-conducting platform 118 has an arc-shaped structure and is arranged along the side wall of the mixing chamber 11. A branch pipe 123 and a branch pipe 124 form a temperature control unit, and each temperature control unit works in conjunction with one heat-conducting platform 118. Each heat-conducting platform 118 is divided into multiple segments, with insulation material between each segment. Similarly, insulation material, such as insulating cotton, is also installed between adjacent heat-conducting platforms 118. It is understood that each segment of the heat-conducting platform 118 is located in a different area on the side wall of the 11. Each segment of the heat-conducting platform 118 is equipped with a temperature sensor (not shown in the figure), which can be a thermocouple temperature sensor, to detect the temperature of its corresponding area.

[0031] A heat-conducting platform 125 is fixedly installed on the side of branch pipe 123 near the heat-conducting platform 118, and a heat-conducting platform 126 is fixedly installed on the side of branch pipe 124 near the heat-conducting platform 118. Both heat-conducting platforms 125 and 126 have gaps with the heat-conducting platform 118, and each section of the heat-conducting platform 118 is equipped with a temperature-conducting component 13 located within the gap. In the first state, the temperature-conducting component 13 transfers heat from branch pipe 123 to the heat-conducting platform 118 via heat-conducting platform 125, heating the area. In the third state, the temperature-conducting component 13 transfers heat from the heat-conducting platform 118 to branch pipe 124 via heat-conducting platform 126, cooling the area. Alternatively, it can be in a second state where neither component is in contact with the other. Example 2

[0032] Reference Figure 5-10 The temperature-conducting component 13 is a controllable structure. Based on the temperature detected by the temperature sensor, it can selectively achieve heat transfer between the heat-conducting platform 118 and branch pipe one 123, or between the heat-conducting platform 118 and branch pipe two 124, or none of these transfers occur. When the temperature sensor detects that the temperature of a region is too high, the temperature-conducting component 13 in that region can be controlled to achieve heat conduction between the heat-conducting platform 118 and branch pipe one 123, thus heating that region. When the temperature sensor detects that the temperature of a region is too low, the temperature-conducting component 13 in that region can achieve heat conduction between the heat-conducting platform 118 and branch pipe two 124, thus cooling that region.

[0033] Specifically, the temperature-conducting assembly 13 includes: step block one 1310 and step block two 1311. Step block one 1310 is located in the gap between heat-conducting platform one 125 and heat-conducting platform 118, and step block two 1311 is located in the gap between heat-conducting platform two 126 and heat-conducting platform 118. Guide rod 133 passes through step block one 1310 and step block two 1311 and slides in cooperation with step block one 1310 and step block two 1311. The working end of electric telescopic rod 132 is fixedly connected to guide rod 133. Retaining rings 134 are fixed at both ends of guide rod 133, and the two retaining rings 134 respectively abut against the opposite sides of step block one 1310 and step block two 1311. An intermediate ring 135 is provided in the middle of the guide rod 1333. A spring 136 is fixed between the intermediate ring 135 and the first step block 1310, and a spring 136 is also fixed between the intermediate ring 135 and the second step block 1311. A side plate 137 is provided on the mixing chamber 11 to separate multiple heat-conducting platforms 118. An electric telescopic rod 132 is fixedly installed on the side plate 137. It can be understood that when the electric telescopic rod 132 extends, the first step block 1310 abuts against the heat-conducting platform 118 and the first heat-conducting platform 125, thereby realizing heat conduction between the first branch pipe 123 and the heat-conducting platform 118. When the electric telescopic rod 132 retracts, the second step block 1311 abuts against the heat-conducting platform 118 and the second heat-conducting platform 126, thereby realizing heat conduction between the second branch pipe 124 and the heat-conducting platform 118.

[0034] With this configuration, when the temperature sensor detects that the temperature in a certain area is too low, the electric telescopic rod 132 in that area can be extended, thereby controlling the step block 1310 to contact the heat conduction platform 118 and the heat conduction platform 125, thereby achieving heat conduction between the branch pipe 123 and the heat conduction platform 118 to heat the area.

[0035] When the temperature sensor detects that the temperature in a certain area is too high, the electric telescopic rod 132 in that area can be controlled to retract, and the second step block 1311 will come into contact with the heat conduction platform 118 and the second heat conduction platform 126, so as to realize the heat conduction between the second branch pipe 124 and the heat conduction platform 118, and cool down the area. Example 3

[0036] Reference Figure 11-13 A first heat-conducting platform 125 has a first contact surface 1251 on its side near the heat-conducting platform 118, and a second heat-conducting platform 126 has a second contact surface 1261 on its side near the heat-conducting platform 118. Both contact surfaces 1251 and 1261 are inclined in opposite directions. The heat-conducting platform 118 has a first heat-conducting surface 1181 and a second heat-conducting surface 1182, with the first heat-conducting surface 1181 facing the first contact surface 1251 and the second heat-conducting surface 1182 facing the second contact surface 1261. A first step block 1310 is located between the first heat-conducting surface 1181 and the first contact surface 1251, and a second step block 1311 is located between the second heat-conducting surface 1182 and the second contact surface 1261.

[0037] Step 1310 has a first surface 1312 that abuts against heat-conducting surface 1181 and a second surface 1313 that abuts against contact surface 1251. Step 211 has a third surface 1314 that abuts against heat-conducting surface 2182 and a fourth surface 1315 that abuts against contact surface 21261. Thermally conductive silicone pads are provided on the first surface 1312, the second surface 1313, the third surface 1314, and the fourth surface 1315.

[0038] With this design, when step block 1310 and step block 2 1311 move, slippage and friction on the first surface 1312, second surface 1313, third surface 1314, and fourth surface 1315 are avoided, which would cause the thermal conductive silicone to fall off. At the same time, when the electric telescopic rod 132 extends and retracts, it can also generate a squeezing force between the thermal conductive silicone sheet and the contact surface, ensuring a good fit and improving the heat conduction effect.

[0039] The heat-conducting platform 118, ladder block 1310, ladder block 2 1311, heat-conducting platform 125, and heat-conducting platform 2 126 are all made of heat-conducting material. They can be made of heat-conducting copper. Meanwhile, branch pipes 123 and 124 are made of heat-conducting copper pipes and are integrally formed with heat-conducting platforms 125 and 126 to achieve good heat conduction. Branch pipes 123 and 124 are covered with heat-insulating sleeves to prevent heat loss or dissipation.

[0040] During operation or installation: When mixing, the drive rotor 111 rotates. The area where the inner wall of the mixing chamber 11 rubs against the material is hotter, causing the rubber to mature quickly and affecting subsequent processing. At this time, the temperature sensor in this area detects that the temperature is too high (above the set threshold), and then controls the electric telescopic rod 132 in this area to retract, driving the guide rod 133 to move. Then, under the action of the retaining ring 134, the first step block 1310 moves, and through the spring 136, the second step block 1311 moves. This causes the first step block 1310 to disengage from the heat-conducting table 118 and the first heat-conducting table 125, while the second step block 1311 abuts against the heat-conducting table 118 and the second heat-conducting table 126. Heat is conducted between the heat-conducting table 118 and the second branch pipe 124 in this area to achieve cooling and prevent the temperature from becoming too high. During operation, areas where materials have not yet been touched or where the frequency of friction between the materials and the interior is low, such as the area above the two vertical side walls, experience significantly lower temperatures than other areas. This leads to temperature imbalances within the mixing chamber, affecting the mixing quality. Additionally, materials adhering to these areas are prone to condensation upon cooling, causing uneven mixing. When a temperature sensor detects a low temperature (below a set threshold), it controls the extension of the electric telescopic rod 132 in that area. This, in turn, controls the step block 1310 to contact the heat-conducting platform 118 and 125, thereby achieving heat conduction between the branch pipe 123 and the heat-conducting platform 118, heating the area.

[0041] When the temperature is within a suitable range, the electric telescopic rod 132 is in its normal state. At this time, neither step block 1310 nor step block 1311 conducts heat, maintaining a stable temperature in the mixing chamber. To reduce overall power consumption, the electric telescopic rod 132 is linked with an external cooling water pump and a hot water circulation pump. Furthermore, electromagnetic control valves can be installed between main pipe 121 and branch pipe 123, and between main pipe 22 and branch pipe 24. When the temperature in a region is detected as too high, the control valve between branch pipe 123 and main pipe 121 at the corresponding location can be opened, and the cooling water pump can be started. This, combined with the contraction of branch pipe 123, achieves precise cooling. Similarly, when the temperature in a region is too low, the control valve between branch pipe 224 and main pipe 222 at the corresponding location can be opened, and the hot water circulation pump can be started, achieving precise heating.

[0042] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
