Description

Technical Field

[0001] The invention relates to the technical field of internal mixers, and in particular to a mixing chamber system with an automatic cleaning function, a control method and an internal mixer. Background Art

[0002] Internal mixer is a key equipment used in rubber industry to mix and refine rubber materials. During the rubber mixing process, the rubber enters the mixing chamber through the feed port and is evenly mixed with additives such as drug powder. However, during this process, the rubber and drug powder are easily adhered to the upper plug, resulting in a decrease in the mixing effect. Therefore, the upper plug needs to be cleaned regularly to maintain its working efficiency.

[0003] Traditional internal mixer cleaning methods have significant efficiency issues. During the cleaning process, the operator needs to first stop the machine with a sign, then manually switch the machine to manual mode and open the feed door. This process is not only time-consuming, but also requires the operator to frequently go up and down the stairs, increasing labor intensity and safety risks.

[0004] Due to the cumbersome and inefficient cleaning work, production efficiency is seriously affected. Each cleaning requires the machine to stop, which not only reduces the effective working time of the machine, but also may cause delays in production plans and increase the operating costs of the enterprise. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a mixing chamber system and control method and an internal mixer with automatic cleaning function. The system reduces manual intervention through automation technology, improves the efficiency and safety of cleaning, and is expected to significantly improve the overall work efficiency and economic benefits of the internal mixer.

[0006] The purpose of the present invention can be achieved by the following technical solutions: The present invention provides a mixing chamber system with an automatic cleaning function, comprising a mixing chamber body, an upper push bolt arranged on the mixing chamber body, an oil cylinder for driving the upper push bolt to rise and fall, a pressing lump arranged at the lower end of the upper push bolt, and a feeding door arranged on the mixing chamber body, wherein the mixing chamber body is provided with a vent hole; The mixing chamber system further includes a gas storage tank, a pipeline connected to the gas storage tank, a solenoid valve arranged on the pipeline, a dust removal nozzle arranged at the end of the pipeline, and a displacement sensor arranged on the inner wall of the mixing chamber body; The mixing chamber system also includes a controller which is communicatively connected to the solenoid valve, the displacement sensor, and the oil cylinder respectively; The dust removal nozzle is arranged at the vent hole; The displacement sensor obtains its distance relative to the pressing ball in real time. When the pressing ball is lifted upward to a preset height inside the mixing chamber body, the controller instructs the oil cylinder to stop driving the pressing ball and instructs the solenoid valve to open, so that the dust removal air nozzle sprays high-pressure airflow toward the pressing ball, thereby blowing the material on the pressing ball off.

[0007] Furthermore, the mixing chamber body is provided with a plurality of ventilation holes.

[0008] Furthermore, the aperture of the vent hole matches the outer diameter of the dust removal nozzle.

[0009] Furthermore, the pipeline is provided with a plurality of pipelines, and the dust removal air nozzles at the ends of the plurality of pipelines are matched with a vent hole respectively.

[0010] Furthermore, the air storage tank is connected to the air compressor through a pipeline.

[0011] Furthermore, a sealing ring is provided between the vent hole and the dust removal nozzle.

[0012] Furthermore, the displacement sensor is an inductive displacement sensor.

[0013] Furthermore, the controller is one of an x86 architecture, an ARM architecture, and a RISC-V architecture processor; The output rod of the oil cylinder is connected to the push bolt.

[0014] A second aspect of the present invention is a control method for a mixing chamber system with an automatic cleaning function as described above, comprising the following steps: Use displacement sensors to monitor the position of the pressing mass relative to the main body of the mixing chamber in real time; When the displacement sensor detects that the pressing mass is lifted to a preset height, the controller instructs the oil cylinder to stop moving, thereby stopping the pressing mass from rising; At the same time, the controller sends a command to the solenoid valve to open the solenoid valve, so that high-pressure airflow is ejected through the dust removal air nozzle. The high-pressure airflow is ejected to the pressing ball, blowing the material on the pressing ball off, realizing automatic cleaning.

[0015] Furthermore, the method further comprises the following steps: The controller calculates whether the opening time of the solenoid valve reaches the preset time. When the preset time is reached, the controller instructs the oil cylinder to start moving, so that the pressing mass moves downward; When the displacement sensor detects that the pressing block has dropped to a preset height, the controller instructs the oil cylinder to stop moving and the pressing block returns to the working position.

[0016] The third aspect of the present invention also provides an internal mixer, comprising the mixing chamber system with automatic cleaning function as described above.

[0017] Compared with the prior art, the present invention has the following advantages: 1) The mixing chamber system of the present invention realizes automatic cleaning of the upper bolt by integrating displacement sensors, oil cylinders, solenoid valves and controllers, without manual intervention, thus improving cleaning efficiency and safety. It not only saves human resources, but also reduces the problems of flying materials and environmental pollution caused by manual cleaning.

[0018] 2) Using high-pressure airflow through the dust removal nozzle can effectively remove the material on the compaction, avoiding the problems of material residue and incomplete cleaning that may occur in traditional cleaning methods. In addition, the matching design of the dust removal nozzle and the vent hole ensures the maximum dust removal effect.

[0019] 3) The displacement sensor monitors the position of the pressing lump in real time. The controller accurately controls the action of the oil cylinder and the solenoid valve according to the signal fed back by the sensor, thus realizing the precise control of the cleaning process. The precise control not only improves the cleaning efficiency, but also helps to extend the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 It includes a mixing chamber body 1, an upper push bolt 2 arranged on the mixing chamber body 1, a cylinder 3 for driving the upper push bolt 2 to rise and fall, a pressing mass 4 arranged at the lower end of the upper push bolt 2, and a feed door 5 arranged on the mixing chamber body 1. The mixing chamber body 1 is provided with a vent hole 6; the output rod of the cylinder 3 is connected to the push bolt 2.

[0025] The mixing chamber system also includes an air tank 7, a pipeline 8 connected to the air tank 7, a solenoid valve 9 arranged on the pipeline 8, a dust removal nozzle 10 arranged at the end of the pipeline 8, and a displacement sensor 12 arranged on the inner wall of the mixing chamber body 1; In specific implementation, the mixing chamber system further includes a controller 11 which is respectively connected to the electromagnetic valve 9, the displacement sensor 12, and the oil cylinder 3. The oil cylinder 3 can be a servo oil cylinder or other oil cylinder which can be remotely controlled.

[0026] In a specific implementation, the dust removal nozzle 10 is arranged at the vent hole 6; During specific implementation, the displacement sensor 12 obtains its distance relative to the pressing ball 4 in real time. When the pressing ball 4 is lifted upward to a preset height inside the mixing chamber body 1, the controller 11 instructs the cylinder 3 to stop driving the pressing ball 4, and instructs the solenoid valve 9 to open, so that the dust removal air nozzle 10 sprays high-pressure airflow toward the pressing ball 4, thereby blowing the material on the pressing ball 4 off.

[0027] In specific implementation, a plurality of vent holes 6 are provided on the mixing chamber body 1. The aperture of the vent hole 6 matches the outer diameter of the dust removal nozzle 10. A plurality of pipelines 8 are provided, and the dust removal nozzles 10 at the ends of the plurality of pipelines 8 are matched with one vent hole 6 respectively.

[0028] During specific implementation, the air storage tank 7 is connected to the air compressor through a pipeline.

[0029] During specific implementation, the displacement sensor 12 is an inductive displacement sensor.

[0030] In a specific implementation, the controller 11 is one of the x86 architecture, ARM architecture, and RISC-V architecture processors; The principle of the present invention is based on the following key technical points: Accurate position monitoring: The position of the upper push bolt 4 is monitored in real time using the displacement sensor 12 to ensure that it can accurately determine whether the upper push bolt has reached the preset height that needs to be cleaned.

[0031] Automatic control: The controller 11 is the core of the system. It receives the signal from the displacement sensor 12 and automatically controls the operation of the cylinder 3 and the solenoid valve 9 according to a preset program.

[0032] High-efficiency dust removal system: When the upper bolt 4 reaches the preset height, the controller 11 will instruct the solenoid valve 9 to open, and the high-pressure airflow will be ejected through the dust removal nozzle 10 to effectively remove the material on the upper bolt. This high-pressure airflow cleaning method is not only efficient, but also can reduce material loss and environmental pollution.

[0033] Automated cleaning process: The entire cleaning process is automated and does not require manual intervention. When the upper ejector bolt 4 is lifted to a preset height, the controller 11 stops the action of the oil cylinder 3 and starts high-pressure airflow cleaning; after the cleaning is completed, the controller instructs the oil cylinder 3 to move again, causing the upper ejector bolt to drop to the working position and continue the mixing process.

[0034] Safety and environmental protection design: Through automatic control and precise cleaning technology, the present invention reduces the safety risks of manual cleaning, while also reducing material waste and environmental pollution, meeting the safety and environmental protection requirements of modern industrial production.

[0036] This embodiment provides a control method for the mixing chamber system with an automatic cleaning function, comprising the following steps: The displacement sensor 12 is used to monitor the position of the pressing mass 4 relative to the mixing chamber body 1 in real time; When the displacement sensor 12 detects that the pressing mass 4 is lifted to a preset height, the controller 11 instructs the oil cylinder 3 to stop moving, thereby stopping the lifting action of the pressing mass 4; At the same time, the controller 11 sends a command to the solenoid valve 9 to open the solenoid valve 9, so that the high-pressure airflow is ejected through the dust removal nozzle 10, and the high-pressure airflow is ejected to the pressing ball 4 to blow off the material on the pressing ball 4 to achieve automatic cleaning.

[0037] The controller 11 calculates whether the opening time of the solenoid valve 9 reaches a preset time. When the preset time is reached, the controller 11 instructs the oil cylinder 3 to start the action, so that the pressing mass 4 moves downward; When the displacement sensor 12 detects that the pressing block 4 has dropped to a preset height, the controller 11 instructs the oil cylinder 3 to stop moving, and the pressing block 4 is back in the working position.

[0038] Example 3

[0039] This embodiment provides an internal mixer, including the mixing chamber system with automatic cleaning function as described above. The internal mixer is integrated with the mixing chamber system with automatic cleaning function, and has the following characteristics: The automatic cleaning of the upper ejector pin 4 is achieved through the precise control of the displacement sensor 12 and the controller 11. During the mixing process, the rubber and the powder are easily adhered to the upper ejector pin, and the automatic cleaning function ensures the consistency of the mixing effect and the efficient operation of the equipment.

[0040] The dust removal nozzle 10 and the vent hole 6 of the internal mixer enable the high-pressure airflow to effectively remove the materials on the upper ejector bolt, thereby improving the cleaning efficiency and reducing the material loss and environmental pollution.

[0041] The displacement sensor 12 monitors the position of the upper push bolt 4 in real time, and the controller 11 accurately controls the actions of the oil cylinder 3 and the electromagnetic valve 9 according to the signal fed back by the sensor, thereby ensuring the accuracy of the cleaning process and the stability of the equipment.
