Description

Technical Field

[0001] The invention belongs to the technical field of cleaning of mixing systems, in particular to a mixing system with an automatic cleaning function. Background Art

[0002] The internal mixer is a key equipment for mixing and refining rubber materials in the rubber industry. During the rubber mixing process, the rubber enters the mixing chamber from the feed port and is pressed down by the upper push bolt. The drug powder and the rubber will adhere to the upper push bolt and the pressure ball during the mixing process, and the upper push bolt and the pressure ball need to be cleaned. However, the existing cleaning method requires the machine to be shut down and then the operator switches the machine to manual mode in the upstairs operating cabinet, and then the operator enters the mixing chamber to operate. However, this method requires real-time attention to the mixing situation in the mixing chamber. At the same time, impurities on the pressure ball may adhere to the product due to untimely discovery, resulting in impure materials and unqualified product quality. At the same time, this cleaning method also seriously wastes labor costs, has low cleaning efficiency, and affects production efficiency. Moreover, when personnel enter the mixing chamber to operate, this cleaning method has certain safety hazards. Therefore, it is urgently necessary to design a mixing system with automatic cleaning function to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a mixing system with an automatic cleaning function, which solves the problem that the existing cleaning method mentioned above is not intelligent and cannot monitor the adhesion on the upper push pin and the pressure ball in real time, resulting in impure products and certain safety hazards when entering the mixing room for operation.

[0004] In order to solve the above technical problems, the present invention provides a mixing system with automatic cleaning function, comprising a mixing chamber body, a pressing block, an upper push bolt, a plurality of air storage tanks, a dust removal air nozzle and a control unit, wherein the pressing block is arranged in the mixing chamber body, the lower end of the upper push bolt passes through the mixing chamber body and is connected to the pressing block, and the upper end is connected to a driving mechanism, and a plurality of vent holes are opened on the outer wall of the mixing chamber body.

[0005] Several gas storage tanks are arranged on the outside of the mixing chamber body, each of the gas storage tanks is connected to a ventilation pipe, and the dust removal air nozzle is installed at the air outlet end of each ventilation pipe. Each dust removal air nozzle passes through each ventilation hole and extends into the mixing chamber body, and is located on one side of the pressing ball. A sensing element is provided on the inner wall of the mixing chamber body, and the sensing element is located below the ventilation hole. A shut-off piece is provided on each ventilation pipe, and the control unit is connected to the sensing element, each shut-off piece and the driving mechanism.

[0006] Furthermore, the driving mechanism is an oil cylinder, and an output rod of the oil cylinder is connected to the upper ejector bolt.

[0007] Furthermore, the vent hole and the dust removal nozzle are sealed by a sealing ring.

[0008] Furthermore, the sensing element is an inductive displacement sensor.

[0009] Furthermore, the shutoff member is a solenoid valve.

[0010] Furthermore, the control unit is one of an x86 architecture processor, an ARM architecture processor, and a RISC-V architecture processor.

[0011] Furthermore, each of the air storage tanks is connected to an air compressor via a ventilation pipe.

[0012] Furthermore, a feeding door is provided on the mixing chamber body.

[0013] A control method for a mixing system with an automatic cleaning function is provided, wherein the mixing system with an automatic cleaning function is used for control, and the specific steps of the control method are as follows:

[0014] S1. Preset the height used for pressing and cleaning in the control unit, and preset the opening and closing time of the solenoid valve;

[0015] S2. During mixing and cleaning, the inductive displacement sensor monitors and obtains the position of the pressing mass relative to the inner cavity of the mixing chamber in real time;

[0016] When the pressing mass needs to be cleaned, the control unit controls the driving mechanism to move so that the upper push bolt drives the pressing mass to move. When the inductive displacement sensor detects that the pressing mass is lifted to a preset height, the control unit sends a stop command to the driving mechanism, and the driving mechanism stops moving, thereby stopping the lifting action of the pressing mass.

[0017] S3, at the same time, the control unit sends an opening instruction to the air compressor, the air compressor is turned on, and the gas in several gas tanks is pressurized by the air compressor. At the same time, the control unit sets the number of solenoid valves to be opened, and calculates the opening time of the solenoid valve. When the preset opening time of the solenoid valve is reached, the control unit sends an opening instruction to the corresponding solenoid valve, and the corresponding solenoid valve is opened. The high-pressure airflow in the gas tank connected to the corresponding solenoid valve passes through the ventilation pipe and is sprayed from the dust removal nozzle onto the pressing ball to blow off the material on the pressing ball, thereby realizing automatic cleaning;

[0018] S4, the control unit calculates whether the closing time of the solenoid valve reaches the preset time. After the preset time is reached, the control unit sends a start instruction to the drive mechanism, and the drive mechanism starts to move so that the upper push bolt drives the pressure ball to move downward;

[0019] When the inductive displacement sensor detects that the pressing block has dropped to a preset height, the control unit instructs the driving mechanism to stop the action and the pressing block returns to the working position.

[0020] Beneficial effects of the present invention: The mixing system of the present invention realizes automatic cleaning of the upper ejector bolt and the pressing lump through the control unit and the sensing member connected to the control unit, each cut-off member and the driving mechanism, without manual intervention, thereby improving the cleaning efficiency and safety, saving human resources, reducing the flying of materials and environmental pollution caused by manual cleaning, and preventing the occurrence of safety accidents at the same time;

[0021] The air in the air tank is pressurized by an air compressor to turn the gas in the air tank into high-pressure gas, and the high-pressure gas is sprayed through the dust removal nozzle to effectively remove the materials on the pressed mass, avoiding the problems of material residue and incomplete cleaning that may occur in traditional cleaning methods;

[0022] The inductive displacement sensor monitors the position of the pressing lump in real time. The control unit 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.

[0023] The control unit improves the cleaning effect by setting the number and position of the selectively enabled solenoid valves, and at the same time can reduce the loss of electric energy consumption as needed without reducing the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A control method for a mixing system with an automatic cleaning function uses a mixing system with an automatic cleaning function for control, and the specific steps of the control method are as follows:

[0034] The height used for cleaning the pressing mass 2 is preset in the control unit 6, and the opening and closing time of the electromagnetic valve is preset;

[0035] During mixing and cleaning, the inductive displacement sensor monitors and obtains the position of the pressing mass 2 relative to the inner cavity of the mixing chamber body 1 in real time;

After the preset time is reached, the control unit 6 sends a start instruction to the driving mechanism 7, and the driving mechanism 7 starts to act so that the upper push bolt 3 drives the pressing mass 2 to move downward;
