Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of rubber hose processing, and more specifically, to a cooling device for a rubber mixing mill used in rubber hose processing. Background Technology
[0002] In the rubber hose manufacturing process, the temperature of the mixing rollers in the rubber mixing mill is a core parameter affecting the quality of the rubber compound. During mixing, the rubber raw material generates a large amount of heat under the extrusion and friction of the rollers. If the temperature is too high, it may cause premature vulcanization and molecular chain breakage in the rubber, thereby affecting the plasticity, uniformity, and subsequent processing performance of the rubber compound, ultimately reducing the strength and service life of the rubber hose. Therefore, effectively cooling the mixing rollers is a crucial step in ensuring the quality of the mixed rubber.
[0003] Currently, rubber mixing mills used for rubber hose processing have significant drawbacks in terms of cooling, as it is difficult to achieve precise temperature reduction of the mixing rollers through external cooling methods. Traditional rubber mixing mills mostly rely on internal water cooling, that is, heat is removed by circulating water through the water channels inside the rollers. However, this method is affected by the water flow distribution and the thermal conductivity of the roller walls, resulting in uneven cooling, especially in the ends and middle areas of the mixing rollers, where excessive temperature differences are likely to occur.
[0004] For high-viscosity rubber or long-term continuous production scenarios, the limitations of internal cooling are even more pronounced: heat accumulation leads to a continuous rise in roller surface temperature, which not only exacerbates rubber adhesion problems but may also cause scorching of the rubber compound due to temperature runaway. Furthermore, the maintenance cost of internal cooling systems is high; blockages or leaks in the water channels require machine shutdown for repairs, severely impacting production continuity. Therefore, the lack of efficient external cooling devices has become a significant bottleneck restricting the temperature control accuracy of rubber mixing mills and affecting the processing quality of rubber hoses. Developing suitable external cooling devices has become an urgent industry need. Utility Model Content

[0031] like Figures 1-3 As shown, a cooling device for a rubber mixing mill for processing rubber hoses according to an embodiment of this disclosure is illustrated, comprising:
[0032] A base frame 1 and a top plate 2, wherein the top plate 2 is mounted on the base frame 1;
[0033] The housing 3 and the position adjustment component 5 are provided. The housing 3 is disposed on the top of the top plate 2, and the position adjustment component 5 is disposed on the bottom cover plate and the base frame 1.
[0034] Cooling assembly 4 is disposed in the housing 3;
[0035] The cooling assembly 4 includes an inner water tank 4-1, which is disposed inside the outer shell 3. A fitting cavity plate 4-2 is disposed on the top of the outer shell 3. A plurality of return pipes 4-3 are connected between the top end of the inner water tank 4-1 and the fitting cavity plate 4-2. A plurality of water pumps 4-4 are disposed at the bottom of the outer shell 3. The suction end of the water pumps 4-4 is connected to the inner water tank 4-1. A water collection cover 4-5 is disposed at the bottom of the outer shell 3. The output end of the water pumps 4-4 is connected to the water collection cover 4-5. A plurality of water inlet pipes 4-6 are connected between the top of the water collection cover 4-5 and the fitting cavity plate 4-2.
[0036] In some examples, a cooling treatment component 4 is designed to achieve efficient cooling of the rubber mixing roller. This component includes an inner water tank 4-1 inside the outer shell 3 for storing low-temperature cooling water. The bonding cavity plate 4-2 on the top of the outer shell 3 is made of thermally conductive material, and the plate surface is adapted to the curvature of the bottom of the rubber mixing roller so that it can fit tightly. The return pipes 4-3 between one end of the top of the inner water tank 4-1 and the bonding cavity plate 4-2 are evenly distributed, and the two ends are connected to the inner water tank 4-1 and the bonding cavity plate 4-2 respectively through flanges to form a return water passage. The water pump 4-4 at the bottom of the outer shell 3 is fixed by a bracket. The suction end is connected to the bottom of the inner water tank 4-1 through a pipe, which can draw low-temperature water from the inner water tank 4-1. The water collection cover 4-5 at one end of the bottom of the outer shell 3 is an arc-shaped cavity, which is connected to the output end of the water pump 4-4 through a pipe. The water inlet pipes 4-6 between the top of the water collection cover 4-5 and the fitting cavity plate 4-2 are evenly distributed, and both ends are connected to the water collection cover 4-5 and the fitting cavity plate 4-2 respectively, forming a water inlet passage.
[0037] During operation, water pump 4-4 starts, drawing low-temperature water from inner water tank 4-1 and sending it to water collection hood 4-5 through the output end. Water collection hood 4-5 evenly distributes the water flow to each water inlet pipe 4-6. The low-temperature water flows into bonding chamber plate 4-2 through water inlet pipe 4-6. Bonding chamber plate 4-2 is in close contact with the bottom of rubber mixing roller, absorbing the heat generated by rubber mixing roller during the rubber mixing process, thus raising the temperature of the low-temperature water. The heated water flows back to inner water tank 4-1 through return pipe 4-3, completing one cycle. Continuous circulation achieves continuous cooling of rubber mixing roller. The inner water tank 4-1 provides storage space for cooling water, ensuring continuous water circulation. The heat-conducting material and arc design of the bonding chamber plate 4-2 ensure a tight fit with the rubber mixing roller, maximizing heat transfer efficiency. The return pipe 4-3 and the inlet pipe 4-6 form a closed loop, allowing the cooling water to be reused and reducing water waste. The water pump 4-4 provides power for water circulation, ensuring stable water flow and improving heat dissipation efficiency. The water collection cover 4-5 evenly distributes water, ensuring balanced water flow in each inlet pipe 4-6 and uniform cooling across all areas of the bonding chamber plate 4-2. This component, through the combination of water circulation and tight fit, achieves efficient and uniform cooling of the rubber mixing roller, ensuring a stable rubber mixing process.
[0038] like Figures 1-3As shown in the figure, the position adjustment component 5 in this embodiment includes a pair of uprights 5-1, both of which are fixed on the base frame 1. A telescopic cylinder 5-2 is vertically installed on the base frame 1. The output end of the telescopic cylinder 5-2 is connected to the top plate 2. Several movable rods 5-3 are provided at the bottom of the top plate 2. The lower end of the movable rods 5-3 is movably fitted inside the top of the base frame 1. A pair of long grooves 5-4 are opened on the surface of the top plate 2. A slide rail 5-5 is provided in each of the long grooves 5-4. Both ends of the bottom of the outer shell 3 are slidably connected to the slide rail 5-5. A transmission groove 5-6 is opened on the surface of the top plate 2. A drive screw 5-7 that is driven to rotate by electricity is provided in the transmission groove 5-6. The drive screw 5-7 is connected to the bottom of the outer shell 3 by a threaded engagement.
[0039] In some examples, to achieve precise adjustment of the height and horizontal position of the outer casing 3, a position adjustment component 5 is designed. This component includes symmetrically distributed uprights 5-1 on the base frame 1, which are fixed by welding. A telescopic cylinder 5-2 is vertically installed on the top of the uprights 5-1, and its output end is connected to the center of the bottom of the top plate 2 through a flange, which can drive the top plate 2 to rise and fall. Movable rods 5-3 at the bottom of the top plate 2 are evenly distributed, and their lower ends are movably fitted into the through holes at the top of the base frame 1 through sliding sleeves, sliding synchronously with the rise and fall of the top plate 2. Long grooves 5-4 are opened along the length of the surface of the top plate 2, and slide rails 5-5 are fixed in the long grooves 5-4. The sliders at both ends of the bottom of the outer casing 3 are slidably connected to the slide rails 5-5, allowing the outer casing 3 to move horizontally along the slide rails 5-5. Transmission grooves 5-6 on the surface of the top plate 2 are perpendicularly distributed to the long grooves 5-4. A drive screw 5-7 is rotatably connected to the transmission groove 5-6 through bearings, and one end is connected to the output end of the motor, which is driven by electricity to rotate. The drive screw 5-7 and the threaded block at the bottom of the outer casing 3 are threaded together to form a screw drive structure.
[0040] When adjusting the height, the telescopic cylinder 5-2 extends and retracts, causing the top plate 2 to rise or fall. The movable rod 5-3 slides along the through hole of the base frame 1, providing guidance and support for the top plate 2 to prevent deviation, thereby driving the outer shell 3 to rise and fall synchronously to adapt to rubber mixing rollers of different diameters. When adjusting the horizontal position, the motor drives the drive screw 5-7 to rotate, which, through the threaded engagement, drives the threaded block at the bottom of the outer shell 3 to move along the drive screw 5-7. The outer shell 3 slides along the slide rail 5-5 in the long groove 5-4 with the slider, realizing horizontal position adjustment and ensuring that the bonding chamber plate 4-2 is precisely aligned with the bottom of the rubber mixing roller. The telescopic drive of the telescopic cylinder 5-2 provides stable lifting power for the top plate 2, and the movable rod 5-3 enhances the structural stability of the top plate 2 to avoid shaking during lifting and lowering. The sliding engagement of the slide rail 5-5 and the slider provides guidance for the horizontal movement of the outer shell 3, ensuring smooth movement. The screw drive of the drive screw 5-7 realizes precise adjustment of the horizontal position of the outer shell 3, which facilitates control of the bonding degree between the bonding chamber plate 4-2 and the rubber mixing roller. This component combines lifting drive with horizontal transmission to achieve flexible and precise adjustment of the height and horizontal position of the outer shell 3, ensuring efficient cooperation between the cooling component and the rubber mixing roller.
[0041] For example, such as Figure 1 As shown, the bonding cavity plate 4-2 has an overall W-shaped structure, and the internal curvature of the bonding cavity plate 4-2 matches the rubber mixing roller.
[0042] In some examples, the bonding chamber 4-2 is W-shaped with its internal curvature matching the mixing rollers, allowing for the simultaneous bonding of multiple mixing rollers. The W-shaped structure ensures close contact between the chamber and each mixing roller, increasing the heat dissipation area. The curvature matching ensures tight bonding, improves heat transfer efficiency, and allows for uniform cooling of each mixing roller, preventing localized overheating that could affect the quality of the rubber compound. Simultaneously, the W-shaped design saves space and adapts to the cooling requirements of multi-roll mixing mills.
[0043] For example, such as Figure 1 As shown, a pair of circulating water exchange pipes 6 are provided on one side of the inner water tank 4-1.
[0044] In some examples, the circulating water exchange pipe 6 on one side of the inner water tank 4-1 can be connected to an external water source and drainage system. The water in the inner water tank 4-1 can be periodically replaced through the pipe, draining the heated water and replenishing it with cooler water to ensure stable cooling. No machine shutdown is required during water changes, achieving continuous cooling and preventing excessively high water temperatures from affecting the cooling of the rubber mixing rollers, thus improving the continuous working capacity of the device and ensuring the smooth operation of the rubber mixing process.
[0045] For example, such as Figure 1 As shown, the bonding cavity plate 4-2 is made of a material with good thermal conductivity.
[0046] In some examples, the bonding chamber 4-2 is made of a material with good thermal conductivity, which can quickly absorb the heat from the rubber mixing roller. The high thermal conductivity of the material accelerates the transfer of heat from the rubber mixing roller to the water inside the chamber, increasing the cooling rate. This material also has good heat resistance and stability, and is not easily damaged during long-term use, ensuring efficient heat conduction when in contact with the rubber mixing roller and maintaining the cooling effect of the cooling treatment component 4.
[0047] In actual use: According to the specifications of the rubber mixing roll, the telescopic cylinder 5-2 drives the top plate 2 to rise and fall, the movable rod 5-3 assists in guiding, and the height of the outer shell 3 is adjusted so that the bonding cavity plate 4-2 is close to the rubber mixing roll. The drive screw 5-7 drives the outer shell 3 to move along the slide rail 5-5 to ensure that the W-shaped cavity plate is precisely bonded to the roll surface. During cooling, the water pump 4-4 draws cold water from the inner water tank 4-1, and it is diverted to the water inlet pipe 4-6 through the water collection cover 4-5. After absorbing the heat of the roll body in the bonding cavity plate 4-2, the cold water returns to the inner water tank 4-1 through the return pipe 4-3. The circulating water exchange pipe 6 regularly replaces the water to maintain a low temperature, achieving uniform and efficient cooling of the rubber mixing roll throughout the process, which is suitable for continuous production needs.
