Description

Technical Field

[0001] The invention relates to the technical field of cotton filling machines and recovery devices, in particular to a temperature-controlled toy cotton filling machine and a cotton dust recovery device, a temperature-controlled cotton filling method and a temperature control method in a cotton storage bin. Background Art

[0002] A plush toy filling machine is an automated device used to fill fluffy cotton into plush toys to make them softer and more comfortable. Previous filling machines were generally composed of a filling device, a compressed air system, and a control system. Cotton wool is a material that easily absorbs moisture. During transportation, changes in the processing environment or weather changes, the air becomes more humid, causing the cotton wool to easily form small clumps inside. Previous cotton filling machines were unable to monitor the temperature and humidity of the cotton wool in real time, resulting in the inability to spray out the clumps of cotton wool or clogging them at the cotton outlet pipe. Especially for filling cotton in different toys, the cotton wool does not reach a certain drying temperature, which greatly affects the metering of cotton during filling. Some are equipped with another dryer for assistance, but the same device is not used to control temperature and humidity. The structure is complex and the overall usability is poor. In addition, since the cotton outlet pipe is directly connected to the air pump, it is inconvenient to clean the inside of the cotton outlet pipe, which can easily cause damage to mechanical equipment or affect the processing progress, and affect the filling amount or the quality of the plush toys after filling. At the same time, the fine cotton wool in the cotton filling pipe of the cotton filling machine is easily splashed and diffused into the air during filling, which not only causes a certain amount of waste, but is also easily inhaled by people, or falls to the ground to pollute the environment, making it inconvenient for subsequent cleaning.

[0003] Therefore, it is necessary to provide a temperature-controlled toy cotton filling machine and a cotton dust recovery device, as well as a temperature-controlled cotton filling method and a temperature control method in a cotton storage bin, which can prevent cotton from flying around, monitor the temperature and humidity of the air in the cotton filling machine in real time, keep the air and cotton in the cotton filling machine dry, and facilitate cleaning of the cotton outlet pipe.

[0017] A cotton dust recovery device is a combination of the hot air blowing mechanism, cotton loosening mechanism, cotton air pump and recovery bin of the above-mentioned controlled toy cotton filling machine, which collects the fallen solid cotton wool and the cotton wool floating above the cotton collecting bucket and around the cotton outlet pipe.

[0018] A method for controlling the temperature in a cotton storage bin of the temperature-controlled toy cotton filling machine as described above comprises the following steps:

[0019] Set certain values ​​for the temperature and humidity in the cotton storage bin. When the temperature and humidity are not within the specified range, cotton filling will not be carried out. At the same time, when the temperature difference between the temperature detected by temperature sensor 1 and the temperature detected by temperature sensor 2 is greater than 2°C, cotton filling will not be carried out. At the same time, the controller controls the drive motor and the hot air blower to increase the power, and accelerates the stirring and drying of the cotton and humid air in the cotton storage bin to achieve uniform temperature control in the cotton storage bin. At the same time, adjust the humidity. When the temperature difference between the two places reaches a uniform temperature less than or equal to 2°C, and reaches the set temperature and humidity values, cotton filling will be carried out.

[0020] A cotton filling method based on the temperature-controlled toy cotton filling machine as described above comprises the following steps:

[0021] S1, putting cotton wool into the cotton storage bin through the feed cover, starting the driving motor to drive the rotating rod and the stirring rod to rotate and stir the cotton wool to make it more fluffy;

[0022] S2. The temperature and humidity in the cotton storage bin are set to certain values. If the temperature and humidity are not within the specified range, cotton filling is not performed. When the temperature sensor 1 detects the temperature in the cotton storage bin and the temperature sensor 2 detects the temperature at the connecting port, when there is a lot of moisture in the air in the cotton storage bin, the temperature in the cotton storage bin will gradually decrease. Moreover, since there is hot air blown out by the hot air blower at the connecting port, the temperature difference between the cotton storage bin and the connecting port will continue to increase. When the temperature difference between the temperature detected by the temperature sensor 1 and the temperature detected by the temperature sensor 2 is greater than 2°C, cotton filling is not performed, indicating that there is moisture in the air or cotton wool in the cotton storage bin (2). The cotton wool will absorb moisture in the air and agglomerate into agglomerates. At this time, by increasing the power of the hot air blower, increasing the air volume and the temperature of the hot air blown out, a high-temperature dry airflow is quickly added to the cotton storage bin. At the same time, the driving motor increases the power to speed up the rotation speed of the stirring rod, thereby realizing rapid stirring and drying of the cotton wool in the cotton storage bin and removing moisture from the air in the cotton storage bin.

[0023] S3. When the temperature difference between the temperature detected by the temperature sensor 1 and the temperature detected by the temperature sensor 2 is less than or equal to 2°C, it indicates that the air in the cotton storage bin is relatively dry, and there is no risk of cotton wool absorbing moisture. The drive motor and the hot air blower are restored to their original power, and cotton filling is performed;

[0024] S4. Connect the cotton filling port of the toy to the end of the cotton outlet pipe, start the cotton filling air pump to suck cotton from the suction pipe, and connect the cotton outlet pipe to spray cotton into the toy through the discharge pipe. During the cotton filling process or after the cotton filling is completed, the cotton falling from the toy or the cotton outlet pipe falls into the cotton collecting bucket, and slides to the flat blowing nozzle through the slope formed between the bottom of the cotton collecting bucket and the bottom of the recovery bin;

[0025] S5. Start the hot air blower. The hot air blower continuously blows air upwards through the air duct and the flat blowing nozzle to blow the cotton wool in the recovery bin back into the cotton storage bin through the connecting port. At the same time, hot air is blown into the cotton storage bin to keep the cotton storage bin dry. During this period, the situation of the cotton wool in the cotton storage bin and the recovery bin can be observed in real time through the observation window and the humidity sensor.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The toy cotton filling machine of the present invention is provided with a temperature sensor 1 at the upper part of the cotton storage bin, and a temperature sensor 2 at the connecting port between the lower part of the cotton storage bin and the recovery bin. When working, the temperature sensor 1 and the temperature sensor 2 detect the temperature of the upper part and the connecting port of the cotton storage bin in real time, and set the temperature and humidity in the cotton storage bin to certain values. If the temperature and humidity are not within the specified value range, cotton filling is not performed. At the same time, when the temperature difference between the temperature detected by the temperature sensor 1 and the temperature detected by the temperature sensor 2 is greater than 2°C, cotton filling is not performed. At the same time, the controller controls the driving motor and the hot air blower to increase the power, so as to fill the cotton wool and moist air in the cotton storage bin. The stirring and drying are accelerated to adjust the temperature and humidity. When the temperature difference between the two places reaches a uniform temperature less than or equal to 2°C, the cotton filling work is carried out. The temperature sensors and temperature sensors at the two places monitor the air and temperature in the cotton storage bin in real time, and realize the effect of temperature-controlled cotton filling to prevent the cotton from absorbing water and agglomerating inside. At the same time, by setting up a recovery bin and cooperating with the cotton filling air pump to form a negative pressure environment in the cotton storage bin, the cotton falling above the cotton collecting hopper and around the cotton outlet pipe can be effectively collected to prevent the cotton from floating in the air or falling on the ground, and the cotton in the recovery bin is blown back to the cotton storage bin through the hot air blowing mechanism;

[0028] By combining the hot air blowing mechanism, temperature sensor, loosening mechanism and recovery bin, the cotton wool is loosened and then recovered and blown into the cotton storage bin, so as to prevent the cotton wool from floating in the air or falling on the ground during filling. The simple structure integrates environmental protection, drying temperature adjustment and cotton filling functions, improves the intelligence of equipment use, effectively controls temperature and humidity, and realizes a multi-functional cotton dust recovery device. A cotton dust recovery device is formed to collect the fallen solid cotton wool and the cotton wool floating around.

[0029] By setting an inner tube in the cotton outlet tube, if the inner tube is blocked during the cotton filling process, the inner tube can be directly replaced without replacing the entire equipment, which does not affect the processing progress. At the same time, it is convenient for the subsequent cleaning of the cotton inside the inner tube. At the same time, the inner tubes with different end sizes and shapes can be replaced as needed to meet the cotton filling needs of different products.

[0030] The temperature control method of the present invention can effectively ensure the dryness of the cotton in the cotton storage bin, and the temperature-controlled cotton filling method can quickly recycle the scattered cotton and simultaneously blow dry the cotton, achieving overall temperature adjustment and temperature-controlled cotton filling, and avoiding the problem of cotton clogging affecting processing efficiency, and has good adaptability to cotton filling processing of different products.

[0048] The toy cotton filling machine is provided with temperature sensor 1 at the upper part of the cotton storage bin, and temperature sensor 2 at the connecting port between the lower part of the cotton storage bin and the recovery bin. When working, temperature sensor 1 and temperature sensor 2 detect the temperature of the upper part and the connecting port of the cotton storage bin in real time, and set the temperature and humidity in the cotton storage bin to certain values. If the temperature and humidity are not within the specified value range, cotton filling will not be carried out.

The temperature sensors and temperature sensors at the two places detect the temperature in the cotton storage bin. The air and temperature are monitored in real time, and the effect of temperature-controlled cotton filling is achieved to prevent the cotton wool from absorbing water and agglomerating in the middle. At the same time, by setting up a recovery bin and cooperating with the cotton filling air pump to form a negative pressure environment in the cotton storage bin, the cotton wool falling from the cotton collecting hopper can be effectively collected to prevent the cotton wool from floating in the air or falling on the ground, and the cotton wool in the recovery bin is blown back to the cotton storage bin through the hot air blowing mechanism; the cotton wool is loosened and recycled and blown into the cotton storage bin through the hot air blowing mechanism, and the cotton wool is prevented from floating in the air or falling on the ground during cotton filling. The simple structure integrates environmental protection, drying and temperature adjustment, and cotton filling functions, improves the intelligence of equipment use, effectively controls temperature and humidity, and realizes a multi-functional cotton dust recovery device. A cotton dust recovery device is formed to collect the fallen solid cotton wool and the cotton wool floating around.

[0049] A cotton dust recovery device, such as the hot air blowing mechanism 5, the cotton loosening mechanism 7, the cotton air pump, and the recovery bin 3 of the above-mentioned controlled toy cotton filling machine, collects the fallen solid cotton wool and the cotton wool floating above the cotton collecting bucket and around the cotton outlet pipe, thereby collecting the two forms of scattered cotton dust.

[0050] A method for controlling the temperature in a cotton storage bin of the temperature-controlled toy cotton filling machine as described above comprises the following steps:

[0051] The temperature and humidity in the cotton storage bin are set to certain values. When the temperature and humidity are not within the specified range, cotton filling will not be performed. At the same time, when the temperature difference between the temperature detected by the temperature sensor 1 and the temperature detected by the temperature sensor 2 is greater than 2°C, cotton filling will not be performed. At the same time, the controller controls the driving motor and the hot air blower to increase the power, accelerate the stirring and drying of the cotton wool and moist air in the cotton storage bin, so as to achieve uniform temperature control in the cotton storage bin and adjust the humidity at the same time;

[0052] If the temperature difference reaches a uniform temperature less than or equal to 2°C, but the overall temperature is too high, the hot air blower reduces the heat wind force, while the motor still increases the stirring power, and part of the air is brought in from the 3 ports of the recovery bin to cool down until the set temperature value;

[0053] When the temperature difference between the two places reaches a uniform temperature less than or equal to 2°C, and reaches the set temperature and humidity values, the cotton filling work can be carried out.

[0054] The large temperature difference between the upper and lower parts of the cotton storage bin indicates that the cotton wool is not dry enough and cannot be heated quickly and evenly. This indicates that there is moisture in the air or cotton wool in the cotton storage bin (2), and the cotton wool will easily absorb moisture in the air and clump into a mass. This is also a method for testing the dryness of cotton wool in the cotton storage bin. Controlling the temperature at a certain level also prevents excessive drying.

[0055] The above device also forms a temperature and humidity control device.

[0056] A cotton filling method based on the temperature-controlled toy cotton filling machine as described above comprises the following steps:

[0057] S1, putting cotton wool into the cotton storage bin 2 through the feed cover 9, starting the drive motor 19 to drive the rotating rod 22 and the stirring rod 23 to rotate and stir the cotton wool to make it more fluffy;

[0058] S2. The temperature and humidity in the cotton storage bin 2 are set to certain values. If the temperature and humidity are not within the specified range, cotton filling will not be performed. When the temperature sensor 1 31 detects the temperature in the cotton storage bin 2 and the temperature sensor 2 32 detects the temperature at the connecting port 4, when there is more moisture in the air in the cotton storage bin 2, the temperature in the cotton storage bin 2 will gradually decrease. Since there is hot air blown by the hot air blower 11 at the connecting port 4, the temperature difference between the cotton storage bin 2 and the connecting port 4 will continue to increase. When the temperature difference between the temperature and the temperature detected by the temperature sensor 232 is greater than 2°C, cotton filling is not performed, indicating that there is moisture in the air or cotton in the cotton storage bin (2), and the cotton will absorb the moisture in the air and clump into agglomerates. At this time, by increasing the power of the hot air blower 11, the air volume and the temperature of the hot air blown out are increased, so that the high-temperature dry air flow is quickly added to the cotton storage bin 2, and at the same time, the driving motor 19 increases the power to speed up the rotation speed of the stirring rod 23, thereby realizing rapid stirring and drying of the cotton in the cotton storage bin 2, and removing the moisture in the air of the cotton storage bin 2;

[0059] S3, when the temperature difference between the temperature detected by the temperature sensor 1 31 and the temperature detected by the temperature sensor 2 32 is less than or equal to 2°C, and the set temperature and humidity values ​​are reached, it means that the air in the cotton storage bin 2 is relatively dry, and there is no risk of cotton wool absorbing moisture, the driving motor 19 and the hot air blower 11 are restored to their original power, and cotton filling is performed;

[0060] S4, the cotton filling port of the toy is sleeved on the end of the cotton outlet pipe 8, the cotton filling air pump 16 is started to suck cotton from the suction pipe 17, and the cotton is sprayed into the toy through the cotton outlet pipe 8 connected to the material outlet pipe 18. During the cotton filling process or after the cotton filling is completed, the cotton falling from the toy or the cotton outlet pipe 8 falls into the cotton collecting bucket 10, and slides to the flat blowing nozzle 13 through the slope formed between the bottom of the cotton collecting bucket 10 and the bottom of the recovery bin 3;

[0061] S5. Start the hot air blower 11. The hot air blower 11 continuously blows air upwards through the air duct 12 and the flat blowing nozzle 13 to blow the cotton wool in the recovery bin 3 back into the cotton storage bin 2 through the connecting port 4. At the same time, hot air is blown into the cotton storage bin 2 to keep the cotton storage bin 2 dry. During this period, the situation of the cotton wool in the cotton storage bin 2 and the recovery bin 3 can be observed in real time through the observation window 27 and the humidity sensor 24.

[0062] The present invention can quickly recycle the floating cotton wool, and can perform real-time temperature monitoring and adjustment on the cotton storage bin 2 and the connecting port 4 to prevent the cotton wool from absorbing water and agglomerating, thus avoiding the problem of cotton wool clogging and affecting the processing efficiency, making it convenient to clean and replace the inner tube 28, and having good adaptability to the cotton filling processing of different products.

[0063] The temperature control method of the present invention can effectively ensure the dryness of the cotton in the cotton storage bin, and the temperature-controlled cotton filling method can quickly recycle the scattered cotton and simultaneously blow dry the cotton, thereby achieving overall temperature regulation and temperature-controlled cotton filling.

[0064] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
