Description

Technical Field

[0001] This utility model relates to the field of polymer material processing equipment, specifically an elastomer material preparation device. Background Technology

[0002] In the production process of elastomer materials, the performance of the preparation equipment directly affects the product quality, production efficiency, and energy consumption.

[0003] Traditional preparation equipment is prone to problems such as uneven dispersion and filler agglomeration when mixing high-viscosity elastomers, which leads to a decline in the mechanical properties of the material. Utility Model Content

[0004] The present invention aims to provide an apparatus for preparing elastomer materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An apparatus for preparing an elastomer material includes a preparation cylinder connected to a support leg, a top cover detachably connected to the preparation cylinder, a feed hopper connected to the top cover, a discharge pipe connected to the preparation cylinder, a valve connected to the discharge pipe, a stepper motor connected to the top cover, a rotating shaft connected to the output end of the stepper motor, a helical blade connected to the rotating shaft, a support rod connected to the helical blade, a connecting rod connected to the support rod, a scraper connected to the supporting rod, the scraper abutting against the preparation cylinder, a cutting blade connected to the rotating shaft, heating wires connected to the rotating shaft and the helical blade, a controller connected to the preparation cylinder, and the stepper motor and heating wires electrically connected to the controller.

[0007] Preferably, the top cover is connected to a mounting ring one, the preparation cylinder is connected to a mounting ring two, the mounting ring one is threadedly connected to a fixing bolt, and the fixing bolt is threadedly connected to the mounting ring two.

[0008] Preferably, the sidewall of the preparation cylinder is filled with insulating cotton.

[0009] Preferably, the top cover is connected to a sealing ring, which cooperates with the preparation cylinder.

[0010] Preferably, the controller is equipped with a touch screen display, which is electrically connected to the controller.

[0011] Preferably, the preparation cylinder is connected to a temperature sensor, which is electrically connected to the controller.

[0012] Preferably, the heating wire is provided with an independent temperature control circuit, which corresponds to different axial regions of the preparation cylinder.

[0013] Preferably, the scraper is coated with a nanoscale non-stick coating.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0015] (1) This solution incorporates a stepper motor, rotating shaft, spiral blades, support rods, connecting rods, scraper, and cutting blades. The stepper motor drives the rotating shaft to rotate, which in turn drives the spiral blades, cutting blades, and scraper to work together. The spiral blades promote the circulation of materials, while the high-speed rotation of the cutting blades forcefully breaks up agglomerated raw materials. The combination of these components ensures more uniform dispersion of the elastomer raw materials, effectively solving the problems of uneven mixing and particle agglomeration in traditional equipment. At the same time, the scraper continuously cleans the cylinder wall, preventing the adhesion of high-viscosity materials and ensuring stable product quality for each batch. This reduces the need for secondary manual processing. While cleaning the adhered materials, the scraper also creates forced disturbance to the high-viscosity fluid in the boundary layer, ensuring that all materials participate in effective mixing. Furthermore, the rotating shaft and spiral blades have built-in heating wires, allowing the materials to be heated while being stirred. The heat directly acts on the mixing process, accelerating the temperature rise while avoiding local overheating that could lead to material performance degradation, effectively improving the mechanical properties and molding quality of the elastomer material.

[0016] (2) By setting mounting ring one, mounting ring two, and fixing bolts, the top cover and preparation cylinder can be quickly disassembled and installed. Compared with traditional welding or fixed structures, the disassembly and assembly process can be completed with only simple tools, greatly shortening the equipment cleaning and maintenance time. It can quickly expose the inside of the equipment, making it easy to clean residual materials, effectively avoiding the risk of cross-contamination between batches caused by material residues, and improving production flexibility.

[0017] (3) By setting up insulation cotton in conjunction with heating wire, the insulation cotton effectively blocks heat from spreading outward, reduces energy loss during the heating process, and concentrates heat on the material, avoiding repeated heating and energy waste caused by heat loss in traditional equipment. This not only reduces the energy consumption of the equipment but also maintains a stable temperature inside the cylinder, ensuring that the heating wire achieves efficient heating with lower power, improving energy utilization and contributing to green production.

[0018] (4) By setting a sealing ring, the sealing ring fits tightly against the cylinder wall during the high-temperature mixing process of the elastomer material, preventing the leakage of harmful gases generated by material volatilization; the installation ring and bolts further enhance the sealing stability and avoid leakage due to equipment vibration or pressure changes. It can effectively improve the workshop operating environment, reduce the health threat of harmful gases to operators, and comply with environmental protection regulations, reduce volatile organic compound emissions, and improve the safety and environmental protection of the production process.

[0019] (5) A touchscreen display enables visualized setting and real-time monitoring of process parameters. Compared to traditional knob controls, this reduces operational errors and allows for the storage of multiple formulations, enabling "one-click switching" of preparation processes for different elastomer materials. The controller presets temperature curves via the touchscreen display and adjusts the heating wire power in real time, ensuring that temperature fluctuations during material mixing are kept within a minimal range. This is particularly suitable for temperature-sensitive elastomer materials such as silicone rubber and polyurethane, avoiding differences in crosslinking degree caused by uneven temperature and improving the stability of product mechanical properties.

[0020] (6) By setting a temperature sensor, the temperature of the material inside the cylinder can be monitored in real time, and the data can be fed back to the controller in a timely manner. The cooperation between the temperature sensor and the controller allows the controller to accurately control the working state of the heating wire according to the set parameters, avoiding the decomposition and carbonization of the material due to excessive temperature, or the incomplete reaction of the material due to excessively low temperature, thereby ensuring the quality stability of the elastomer material and reducing the defect rate caused by temperature deviation.

[0021] (7) By setting up an independent temperature control loop, it is possible to achieve differentiated temperature control at different locations within the preparation cylinder. The independent temperature control loop can adjust the heating power of each area according to these differences, so that the material is at the optimal reaction temperature at different stages, meeting the requirements of complex preparation processes, improving the uniformity and consistency of materials, and enhancing product quality and production efficiency.

[0022] (8) By setting a nano-level non-stick coating, the adhesion between the elastomer material and the scraper surface is greatly reduced. This allows the material to be smoothly pushed and stirred by the scraper, making it less likely to leave residue. When cleaning the equipment, the residual material is easier to remove, reducing the time and manpower required for cleaning, improving the turnover efficiency of the equipment, and providing convenience for continuous production.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0028] like Figure 1-2 The apparatus shown is for preparing elastomeric materials, including a preparation cylinder 4. The preparation cylinder 4 is a cylindrical stainless steel cavity with a mirror-polished inner wall, exhibiting excellent corrosion resistance and easy cleaning, suitable for processing various elastomeric materials. Four support legs 6, made of high-strength structural steel, are evenly connected to the bottom of the preparation cylinder 4 to ensure stability during operation and prevent displacement or shaking due to vibration. A top cover 2 is detachably connected to the top of the preparation cylinder 4, and a feed hopper 1 is connected to the top of the top cover 2. The feed hopper 1 has a tapered design to guide materials smoothly into the preparation cylinder 4, preventing accumulation. A sealing cap is threaded onto the feed hopper 1, providing a reliable seal after feeding to prevent dust from flying. The bottom of the preparation cylinder 4 is connected to a discharge pipe 7, which is connected to a valve 8. The top of the top cover 2 is connected to a stepper motor 12, and the output end of the stepper motor 12 is connected to a rotating shaft 13. The lower part of the outer wall of the rotating shaft 13 is connected to a spiral blade 15, which generates axial thrust when rotating, pushing the material to circulate up and down and enhancing the mixing effect. The spiral blade 15 is connected to several support rods 16, and each support rod 16 is connected to a connecting rod 17. All the connecting rods 17 on each side are connected to a scraper 18. Each scraper 18 is in contact with the inner wall of the preparation cylinder 4. The scraper 18 cleans the cylinder wall synchronously with the stirring process to prevent high-viscosity materials from adhering and ensure that the materials fully participate in the mixing. A rotating shaft 13 is connected to several cutting blades 14, which are evenly distributed in a spiral pattern on the upper part of the rotating shaft 13. The cutting blades 14 are made of cemented carbide and perform powerful shearing and crushing on blocky or agglomerated materials during high-speed rotation, improving the uniformity of dispersion. Heating wires are connected to the rotating shaft 13 and the spiral blades 15 respectively. The heating wires are made of nickel-chromium alloy and are covered with a magnesium oxide insulation layer. The heating wires act directly on the material stirring area, heating while stirring, avoiding the temperature lag and unevenness problems caused by traditional external heating methods. A controller 5 is connected to the outer wall of the preparation cylinder 4. The stepper motor 12 and the heating wires are electrically connected to the controller 5.

[0029] like Figure 1As shown, the bottom of the top cover 2 is connected to a mounting ring 11, and the top of the preparation cylinder 4 is connected to a mounting ring 20. Both mounting rings 11 and 20 are made of stainless steel. Mounting ring 11 is threaded with several fixing bolts 3, each bolt 3 being threadedly connected to mounting ring 20. The inside of the side wall of the preparation cylinder 4 is filled with insulation cotton to reduce heat loss, maintain a stable internal temperature, reduce energy consumption, and protect external operators from high temperatures. The bottom of the top cover 2 is connected to a sealing ring, which fits into the top of the preparation cylinder 4. The sealing ring is made of fluororubber to ensure airtightness and liquid tightness. The controller 5 is equipped with a touch screen 9, which is electrically connected to the controller 5. It supports the visual setting and real-time monitoring of process parameters, providing a user-friendly interface and convenient operation. The controller 5 automatically adjusts the speed of the stepper motor 12 and the power of the heating wire through a preset program to achieve precise control of the stirring intensity and temperature curve, ensuring process repeatability and product quality stability. A temperature sensor is connected to the top of the inner wall of the preparation cylinder 4, and is electrically connected to the controller 5. The temperature sensor can monitor the temperature change in the top area of ​​the preparation cylinder 4 in real time and transmit the collected temperature data to the controller 5 in real time. The heating wires are equipped with independent temperature control loops, each corresponding to a different axial region of the preparation cylinder 4. The controller 5 can precisely control each independent temperature control loop based on the data fed back by the temperature sensor and the preset preparation process parameters, independently adjusting the heating power of the heating wires in different areas. This achieves differentiated temperature control at different axial positions within the preparation cylinder 4, ensuring that the material is in the optimal temperature environment at different reaction stages and meeting the stringent temperature requirements of complex processes. The scraper 18 is coated with a nano-level non-stick coating. During the stirring process of the elastomer material, this coating significantly reduces the adhesion between the elastomer material and the surface of the scraper 18, allowing the material to be smoothly pushed and stirred under the action of the scraper 18, making it less likely to adhere to the surface of the scraper 18. Even if a small amount of material remains, it can be easily removed during subsequent cleaning, greatly reducing cleaning difficulty and time costs, and improving the efficiency and turnover speed of the equipment.

[0030] The specific implementation process is as follows:

[0031] In use, open the sealing cap and feed the elastomer raw materials and additives into the preparation cylinder 4 through the feed hopper 1, then close the sealing cap to ensure airtightness. The controller 5 drives the stepper motor 12 to rotate the shaft 13, the cutting blade 14 breaks up material clumps, the spiral blade 15 promotes material circulation, and the scraper 18 cleans the cylinder wall, creating a comprehensive mixing effect. Simultaneously, a temperature sensor monitors the temperature inside the preparation cylinder 4 in real time and transmits the data to the controller 5. The controller 5 determines whether the current temperature meets the requirements based on the preset preparation process temperature parameters. If the temperature is abnormal, the controller 5 adjusts the power of the heating wire in the corresponding independent temperature control circuit according to the temperature requirements of different axial regions. The heating wire is energized and heats up, directly transferring heat to the material. The controller 5 adjusts the heating power in real time according to the preset temperature curve to ensure that the material completes the plasticization and cross-linking reaction at the optimal process temperature. During the stirring process, the scraper 18, coated with a nano-level non-stick coating, continuously scrapes the material on the inner wall of the preparation cylinder 4. Due to the non-stick coating, the material is difficult to adhere to the surface of the scraper 18, maintaining a good stirring and mixing state at all times. Once the preparation process is complete, open valve 8 of discharge pipe 7 to discharge the prepared elastomer material.
