[0002] Existing interlayer feeding devices are all used for feeding powder materials, and manual docking is carried out during the feeding process, or a cover is arranged at the receiving hopper to avoid the leakage of powder during the feeding process. However, the transportation components are not completely sealed, and it is easy for external air to carry dust and other impurities into the pipeline to pollute the transported materials during transportation. For example, an interlayer feeding device disclosed in a Chinese patent with the application number CN201822119501.8 can perform automatic docking through a lifting docking device to improve the docking efficiency and meet the production requirements. At the same time, although a cover is adopted, it cannot avoid powder leakage and affect the environment. Moreover, the entire transportation device cannot be hermetically treated, which easily causes material loss during transportation, allows the material to leak and pollute the surrounding environment, and also causes the material to come into contact with the external environment, resulting in material contamination, and its use has limitations.

[0022] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0023] Refer to Figures 1-5, in an embodiment of the present utility model, an interlayer airtight automatic feeding device includes: a material bucket storage rack 5 for supporting and storing a discharging bucket 1 containing the material to be fed. The upper surface of the material bucket storage rack 5 is fixedly connected with the discharging bucket 1 which contains the material to be fed. The upper bottom wall of the material bucket storage rack 5 is provided with a valve opening mechanism 3 which is electrically controlled by a scale 7. When the measurement of the scale 7 returns to zero, it receives the electrical signal transmitted by the scale 7 and opens the first valve 4, enabling the material to enter the interlayer material pipe 8 through the first valve 4. The output end of the valve opening mechanism 3 is fixedly connected with the first valve 4. The first valve 4 is located between the discharging bucket 1 and the vent breather 6 and is controlled by the valve opening mechanism 3. After being opened, it allows the material to enter the interlayer material pipe 8. The upper bottom wall of the material bucket storage rack 5 is provided with a rotary clamping cylinder 13 with the model QCKL - 40X10S. After receiving the signal transmitted by the level sensor 9, it can open the horizontally moving cover 2, enabling the discharging bucket 1 to be placed on the material bucket storage rack 5. The rotary clamping cylinder 13 is electrically connected to the level sensor 9. The output end of the rotary clamping cylinder 13 is fixedly connected with the horizontally moving cover 2. During operation, the horizontally moving cover 2 is located between the first valve 4 and the vent breather 6, closing the part where the material bucket storage rack 5 is connected to the discharging bucket 1 to prevent gas and impurities from entering the interlayer material pipe 8 before use. The lower surface of the material bucket storage rack 5 is fixedly connected with a scale 7. There are two scales 7 which are symmetrically distributed. The scale 7 is electrically connected to the valve opening mechanism 3, which can weigh the amount of material in the discharging bucket 1 and perform counting and storage. When the material is falling, the measurement of the scale 7 will gradually return to zero. When the measurement is zero, it transmits an electrical signal to the valve opening mechanism 3 to close the first valve 4;

[0024] One end of the first valve 4 is provided with a vent breather 6 which extracts the air in the interlayer material pipe 8 to achieve airtight feeding. The end of the vent breather 6 far from the first valve 4 is fixedly connected with an interlayer material pipe 8 which transports the material in the discharging bucket 1 on the second floor to the receiving bucket 12 on the first floor. The side inner wall of the interlayer material pipe 8 is fixedly connected with a level sensor 9 which judges whether the material in the interlayer material pipe 8 is less than the installation position of the level sensor 9. After meeting the condition, it can transmit a feeding signal and output a changing electrical signal to monitor the storage amount of the material in real time, thereby controlling the entry, exit and transportation of the material. The end of the interlayer material pipe 8 far from the first valve 4 is fixedly connected with a second valve 10. The second valve 10 is located between the interlayer material pipe 8 and the discharging flexible connection 11. After being opened, it can transport the material in the interlayer material pipe 8 to the receiving bucket 12 through the discharging flexible connection 11. The end of the second valve 10 far from the interlayer material pipe 8 is fixedly connected with a discharging flexible connection 11 which is a flexible airtight interface and can send the material into the receiving bucket 12. The end of the discharging flexible connection 11 far from the second valve 10 is fixedly connected with a receiving bucket 12 which receives the material transported from the discharging bucket 1 on the second floor.

[0025] Inside the drum storage rack 5, a nylon stopper 14 is fixedly connected. An air source interface is formed between the nylon stopper 14 and the drum storage rack 5. The nylon stopper 14 is used to improve the wear resistance of the drum storage rack 5 and increase the service life of the drum storage rack 5. A fixed flange is fixedly connected between the vent breather 6 and the interlayer material pipe 8. The fixed flange is used to increase the airtightness of the device to prevent gas from entering the interlayer material pipe 8 during the use of the device. The upper surface of the vent breather 6 is fixedly connected to the drum storage rack 5. One end of the scale 7 far from the drum storage rack 5 is fixedly connected to the second-floor floor slab 15. The end of the interlayer material pipe 8 far from the vent breather 6 penetrates the upper surface of the second-floor floor slab 15 and extends to the lower surface of the second-floor floor slab 15.

[0026] Working principle: First, start the vent breather 6 to extract the air in the interlayer material pipe 8. Determine whether the material in the interlayer material pipe 8 is less than the installation position of the level sensor 9 through the level sensor 9. After meeting the requirement, transmit a signal indicating that feeding is possible to the rotary clamping cylinder 13. After receiving the signal, the rotary clamping cylinder 13 opens the horizontally moving cover 2. Then, place the discharging drum 1 filled with material on the drum storage rack 5. The scale 7 starts to weigh the discharging drum 1, measure the amount of material in the discharging drum 1, and then count and store it. After that, open the valve 1 4 through the valve opening mechanism 3 for feeding. During the feeding process, the measurement of the scale 7 gradually returns to zero. When the measurement is zero, the scale 7 transmits a signal to the valve opening mechanism 3 to close the valve 1 4 and remove the discharging drum 1. At the same time, close the horizontally moving cover 2. After the conveyed material falls into the interlayer material pipe 8 through the valve 1 4, the interlayer material pipe 8 makes the material pass through the second-floor floor slab 15 and fall to the valve 2 10. Then, open the valve 2 10 to make the material fall into the receiving bucket 12 through the discharging flexible connection 11 to complete the feeding. When the material in the interlayer material pipe 8 is less than the level sensor 9, re-feeding can be carried out, and so on in a cycle to complete the whole process.

[0027] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present invention.
