Description

Technical Field

[0002] In today's medical and elderly care service system, hospitals, rehabilitation centers and nursing homes are facing a severe challenge: a large and growing number of people who cannot eat normally. Due to illness, physical decline or swallowing disorders, they need to rely on nasogastric feeding to obtain nutrition. The physical conditions and nutritional needs of these patients and the elderly vary, requiring nutritionists and dietitians to tailor nutrition plans for them. However, this has led to huge differences in the types and weights of nutritional powders. This highly personalized demand makes the configuration of liquid nutritional meals extremely complicated.

[0003] The traditional method of preparing liquid nutritional meals is extremely dependent on manual labor, and the operation is cumbersome and delicate. Workers need to complete a series of processes such as weighing, adding ingredients, adding water, stirring, canning, screwing caps and cleaning in a short period of time. The tedious work not only easily leads to deviations in variety selection and weight control by workers, but also greatly reduces work efficiency. This cumbersome operation process not only affects the accuracy and timeliness of nutritional meals, but also brings potential health risks to patients due to human errors. Therefore, the development of a set of intelligent and efficient liquid filling equipment has become an urgent need in the medical and elderly care fields.

[0081] See also Fig.11An annular spraying chamber is formed between the inner tube 11 and the filling tube 10, an air inlet pipe 22 connected to the annular spraying chamber is fixedly connected to the filling tube 10, the air inlet pipe 22 is connected to the air outlet pipe of the external blower, one end of the air inlet pipe of the external blower is connected to the air filter cartridge, and a second solenoid valve 23 is provided on the air inlet pipe 22;

[0082] See also Figure 11-13 A support ring 14 is fixedly sleeved on the lower end of the filling pipe 10, a sealing ring 15 is fixedly connected above the support ring 14, a magnetic tube 16 fixedly connected to the filling pipe 10 is provided above the sealing ring 15, a lifting ring 17 is nested in the magnetic tube 16 and slidably abuts against the inner wall of the magnetic tube 16, an extrusion rod 19 is fixedly connected below the lifting ring 17; a magnetic ring 18 is fixedly connected inside the lifting ring 17, and an electromagnetic coil 20 is fixedly connected inside the shell wall of the magnetic tube 16.

[0083] For details, please refer to Figure 14-16 When the filling head 401 performs the filling operation, the following steps are included:

[0084] Step 1: seal the filling bag 8, start the electromagnetic coil 20, the magnetic field generated by the electromagnetic coil 20 drives the magnetic ring 18 and the lifting ring 17 to move downward, and the lifting ring 17 drives the extrusion rod 19 to move downward to squeeze the sealing ring 15, so that the outer wall of the sealing ring 15 abuts against the inner wall of the hard tube 801, so that the filling bag 8 is sealed;

[0085] Step 2: expand the bag 802 and fill the bag 802 with a clean airflow; start the external blower and the second solenoid valve 23, and the external blower injects the clean airflow into the annular blowing cavity through the air inlet pipe 22, and then enters the bag 802, so that the bag 802 is fully expanded, and then the electromagnetic coil 20 is started again, so that the extrusion rod 19 is out of contact with the sealing ring 15, and then the outer wall of the sealing ring 15 is out of contact with the inner wall of the hard tube 801, so that the clean airflow is discharged from the hard tube 801;

[0086] Specifically, by injecting clean airflow into the filling bag 8, the filling bag 8 is stretched open, which is convenient for subsequent injection of dietary powder paste. At the same time, when the bag body 802 is stretched open, the sealing ring 15 is opened to maintain the injection of clean airflow, and the excess clean airflow is discharged from the hard tube 801, thereby reducing the entry of external air into the bag body 802, thereby reducing the entry of dust in the external air into the bag body 802, and at the same time squeezing out the original air in the bag body 802, further improving the cleanliness of the filling bag 8;

[0087] Step 3, filling, first start the second electric push rod 13, the second electric push rod 13 drives the valve core rod 12 to break contact with the inner tube 11, then start the peristaltic pump 403 and adjust the second solenoid valve 23 to reduce the speed of the clean air flow into the bag body 802, and the peristaltic pump 403 injects the dietary powder into the bag body 802;

[0088] Step 4, cleaning. When the amount of dietary powder injected into the bag body 802 reaches the set injection amount, first turn off the peristaltic pump 403, and then start the second electric push rod 13 again, so that the valve core rod 12 re-closes the inner tube 11 and moves to the bottom of the inner tube 11, so that the clean air flow sprays the valve core rod 12. When the spraying time reaches the set value, close the second solenoid valve 23 to complete the filling.

[0089] Specifically, the lower end surface of the valve core rod 12 extending below the inner tube 11 is sprayed and cleaned by a clean airflow, so that the residual meal powder paste adhering to the lower end surface of the valve core rod 12 is brought into the bag body 802 by the airflow, and the valve core rod 12 is cleaned, thereby reducing the probability of residual meal powder paste dripping after the filling head 401 is separated from the filling bag 8, thereby improving the sanitation of the filling site;

[0090] It should be noted that after the clean air flow is sprayed from the annular spray chamber, a high-speed air flow zone is formed around the lower end of the valve core rod 12. The high-speed air flow has a fast flow rate and a low pressure. The dietary powder paste adhered to the lower end surface of the valve core rod 12 is attracted by the high-speed air flow zone and then separated from the valve core rod 12.

[0091] Compared with the conventional filling equipment, the present invention uses an inner tube 11 arranged in the filling tube 10 and connected to a blower to inject a clean airflow into the bag body 802 before the filling of the dietary powder paste, so that the bag body 802 is expanded and the air inside is squeezed out of the bag body 802 by the clean airflow, which is convenient for the subsequent filling of the dietary powder paste and improves the cleanliness of the bag body 802; at the same time, the sealing ring 15 and the elevating squeezing rod 19 arranged on the outside of the filling tube 10 can seal the filling bag 8 when the filling bag 8 is inflated. The inflation efficiency is improved, and the injection of clean airflow is maintained when filling the dietary powder paste, so as to prevent external air from entering the bag body 802 and contaminating the dietary powder paste. In addition, by providing a liftable valve core rod 12, it is convenient to quickly close the inner tube 11 used for filling the dietary powder paste. At the same time, after the filling is completed, the valve core rod 12 extending below the inner tube 11 is sprayed and cleaned with a clean airflow, so as to reduce the dietary powder paste remaining on the filling head 401, reduce the probability of residual dietary powder paste dripping from the filling head 401, and improve the cleanliness of the filling.

[0092] See also Fig.11 and Fig.12 The inner tube 11 is a tapered tube that is wide at the top and narrow at the bottom. Its upper part is a tapered cavity and its lower part is a cylindrical cavity. The upper end of the inner tube 11 is fixedly connected to the inner wall of the filling pipe 10. The valve core rod 12 is a cylindrical rod. After the valve core rod 12 is inserted into the inner tube 11, it slides and abuts against the inner wall of the cylindrical cavity at the lower part of the inner tube 11.

[0093] Specifically, the inner tube 11 is closed by the valve core rod 12 , thereby closing and cutting off the dietary powder paste, while at the same time, the clean airflow continues to be injected into the bag body 802 .

[0094] See also Fig.12 and Fig.13 The extrusion rod 19 is an arc-shaped plate with a pointed tip at the lower end. The sealing ring 15 is an annular structure and its outer end surface is provided with a plurality of vertically distributed raised rings. The upper end of the sealing ring 15 is provided with an opening that cooperates with the extrusion rod 19.

[0095] Specifically, when the extrusion rod 19 moves downward, it is inserted into the inner side of the sealing ring 15 through the opening at the upper end of the sealing ring 15, thereby squeezing the sealing ring 15, causing the sealing ring 15 to expand, and the sealing effect of the sealing ring 15 on the filling bag 8 is improved by providing a plurality of raised rings on the outer wall of the sealing ring 15.

[0096] See also Figure 1-3 The intelligent filling machine for preparing nutritious meals also includes a cleaning component 25, which includes a spray pipe 2501 that penetrates the top cover of the mixing drum 501 and is slidably connected thereto, the spray pipe 2501 is connected to an external water source, and the end of the spray pipe 2501 located in the mixing drum 501 is fixedly connected to a spray head 2511, and the other end of the spray pipe 2501 is fixedly connected to a fourth lifting component 2502 that drives it to move up and down, and the fourth lifting component 2502 is fixedly connected to the support frame 1; the cleaning component 25 also includes a drain pipe 2503 arranged on one side of the filling head 401 and a transverse screw module 2504 fixedly connected to the first lifting component 402.

[0097] Specifically, when the mixing drum 501 is cleaned, the following steps are included:

[0098] Step 1: Start the transverse screw module 2504 to move the filling head 401 to the top of the sewage pipe 2503, and then start the first lifting assembly 402 to drive the filling head 401 to be inserted into the sewage pipe 2503;

[0099] Step 2, start the external water source and the fourth lifting assembly 2502, spray and rinse the inner wall of the mixing drum 501 up and down, and start the peristaltic pump 403 to inject the wastewater generated by cleaning into the drain pipe 2503 through the discharge pipe 21, the feed pipe 24 and the filling head 401 for discharge.

[0100] Compared with the traditional manual disassembly and cleaning of the mixing drum 501, the present invention is provided with a cleaning component 25, which can perform vertical reciprocating spray flushing on the mixing drum 501, and realizes automatic cleaning without disassembling the mixing drum 501. At the same time, the reciprocating spray flushing can improve the cleaning effect and save water. In addition, the discharge pipe 21, the feed pipe 24 and the filling head 401 are cleaned synchronously, which further improves the cleanliness and service life of the equipment.

[0101] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
