At the same time, the intelligent control system monitors and adjusts the pressing parameters in real time, and can optimize the pressing process in time according to actual conditions, avoiding production stagnation or product quality problems caused by inappropriate parameters, thereby improving overall production efficiency.

[0046] Example 2

[0047] Please refer to Figures 1 to 4 As shown, an embodiment of the present invention provides a method for preparing a powder-pressed coated tablet, comprising: the preparation equipment of any one of Example 1, comprising the following steps:

[0048] S1. Raw material mixing

[0049] The main raw materials (85 parts of stearic acid, 7 parts of paraffin, 2.5 parts of titanium dioxide, 5 parts of microcrystalline cellulose, 0.5 parts of sodium stearate), adhesive, release agent, etc. are accurately weighed according to the predetermined formula ratio and placed in a powder mixer in sequence.

[0050] Start the powder mixer and set the mixing time to 30 minutes. The stirring paddle rotates at high speed in the mixing barrel to fully mix the various raw materials to form a uniform mixed powder.

[0051] After the mixing is completed, the mixed powder is fed into the hopper of the rotary dry powder tablet press through the discharge port of the mixing barrel.

[0052] S2. Loading preparation

[0053] Driven by a motor, the feeding screw of the automatic feeding system evenly and continuously conveys the mixed powder in the hopper to the die cavity of the rotary dry powder tablet press.

[0054] The metering device precisely controls the speed of the feeding screw to adjust the quantity, weight and speed of the feeding, ensuring that the slices pressed each time have consistent size and weight.

[0055] S3. Precise feeding control

[0056] The automatic feeding system accurately controls the speed and feeding time of the feeding screw through the metering device according to the preset process requirements to ensure the accurate amount of powder pressed each time.

[0057] At the same time, the intelligent control system monitors the feeding process in real time. If any abnormal situation is found (such as feeding speed is too fast or too slow, powder blockage, etc.), it will automatically adjust the feeding parameters or issue an alarm to prompt the operator to handle it.

[0058] S4, compression molding

[0059] Start the rotary dry powder tablet press, and the upper die and lower die begin to move relative to each other to compress the mixed powder in the die cavity.

[0060] During the pressing process, the sensor detects parameters such as pressure, cavity capacity and pressing speed in real time and transmits the detected data to the processor.

[0061] Based on the received data, the processor adjusts the action of the actuator in a timely manner (such as adjusting the movement speed and pressure of the upper and lower molds) to optimize the pressing process and ensure the quality and consistency of the sliced ​​pieces.

[0062] When the pressure reaches the set value, the pressing process is completed and the sliced ​​tablets are formed. The discharge mechanism of the rotary dry powder tablet press pushes the sliced ​​tablets out of the die cavity and sends them to the subsequent conveyor belt or collection device.

[0063] S5. Real-time monitoring and adjustment

[0064] During the entire pressing process, the intelligent control system continuously monitors the pressing process in real time.

[0065] The sensor continuously detects various parameters during the pressing process (such as pressure, cavity volume, pressing speed, temperature, etc.) and transmits the data to the processor in real time.

[0066] The processor analyzes and evaluates the pressing process in real time based on the received data. If any abnormal situation is found (such as too high or too low pressure, abnormal temperature, etc.), the action of the actuator will be automatically adjusted (such as adjusting the pressure, controlling the start of the cooling device, etc.) to ensure the stability and consistency of the pressing process.

[0067] S6. Subsequent processing and cleaning maintenance

[0068] After the pressing is completed, the sliced ​​pieces are taken out for subsequent processing, such as drying and packaging.

[0069] Use the cleaning nozzle to spray the cleaning fluid to clean the inside of the device to remove residual powder and impurities. The cleaning fluid is discharged to the outside of the device through the drainage device to ensure the cleanliness and normal operation of the equipment.

[0070] Regularly disassemble and clean the powder mixer and rotary dry powder tablet press, check the wear of each component, and replace or repair if necessary.

[0071] Collect dust generated during the production process through dust collection devices and dispose of it safely in accordance with environmental protection requirements;

[0072] By adopting the above technical solution and innovative technologies such as powder pressing process, automatic feeding system and intelligent control system, production efficiency is greatly improved, production cost is reduced, yield rate is increased and production safety is ensured. At the same time, the efficient cleaning and maintenance mechanism extends the service life of the equipment and reduces maintenance costs. The present invention has important application value and promotion prospects in the production of marking stationery in the clothing fabric industry.

[0073] The pressing process in S4 further includes the following steps:

[0074] P1, using sensors to detect parameters such as pressure, cavity volume and pressing speed during the pressing process;

[0075] P2, the processor adjusts the action of the actuator according to the parameters detected by the sensor to optimize the pressing process;

[0076] By adopting the above technical solution, the intelligent control system monitors and adjusts the pressing parameters in real time, and can timely optimize the pressing process according to actual conditions, avoiding production stagnation or product quality problems caused by inappropriate parameters, thereby improving overall production efficiency.

[0077] After the raw material is pressed in S6, the following steps are also included:

[0078] Y1. Use the cleaning nozzle to spray the cleaning fluid to clean the inside of the device;

[0079] Y2. Discharge the cleaning fluid out of the device through the drainage device;

[0080] By adopting the above technical solutions, efficient cleaning and maintenance mechanisms, including easily disassembled and cleaned parts and dust collection devices, reduce equipment failures caused by dust accumulation and other reasons, reduce equipment maintenance and replacement costs, and extend the service life of the equipment.

[0081] The working principle of the present invention is:

[0082] Mixing stage:

[0083] Put the main raw materials (85 parts of stearic acid, 7 parts of paraffin wax, 2.5 parts of titanium dioxide, 5 parts of microcrystalline cellulose, 0.5 parts of sodium stearate), adhesive, release agent, etc. into the powder mixer. The stirring paddle rotates in the mixing barrel to fully mix the various raw materials and provide a uniform mixed powder for subsequent pressing.

[0084] Loading stage:

[0085] The uniformly mixed powder is placed into the hopper of the rotary dry powder tablet press. The feed screw of the automatic loading system transports the mixed powder from the hopper to the die cavity. A metering device precisely controls the feed screw's speed, adjusting the quantity, weight, and speed of the powder fed to ensure the correct amount of powder is pressed each time.

[0086] Suppression phase:

[0087] The upper and lower dies of a rotary dry powder tablet press move relative to each other, compressing the mixed powder in the die cavity to form sliced ​​tablets. During this process, sensors monitor parameters such as pressure, cavity volume, and pressing speed in real time.

[0088] The processor adjusts the action of the actuator according to the parameters detected by the sensor, such as controlling the movement speed and pressure of the upper and lower dies, to optimize the pressing process and ensure the quality and consistency of the sliced ​​pieces.

[0089] Monitoring and adjustment phase:

[0090] The intelligent control system continuously monitors the pressing process in real time and adjusts the pressing parameters in a timely manner based on the feedback information from the sensor to keep the pressing process in the best state at all times.

[0091] Subsequent processing stage:

[0092] After the pressing is completed, the sliced ​​pieces are taken out for subsequent processing, such as drying and packaging.

[0093] Cleaning and maintenance phase:

[0094] Use the cleaning nozzle to spray the cleaning fluid to clean the inside of the device to remove residual powder and impurities.

[0095] The cleaning fluid is discharged outside the device through the drainage device to keep the equipment clean and in normal operation, thus extending the service life of the equipment.
