For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 1 , Figure 2As shown, the automatic feeding control system for preventing coating material breakage and filtering agglomerated materials in this embodiment includes a first buffer bin 1, a second buffer bin 2, a third buffer bin 3, and a bucket elevator 19. The first buffer bin 1, the second buffer bin 2, and the third buffer bin 3 have identical structures and are used to temporarily store materials, ensuring a continuous material supply. A first feed level sensor 4, a second feed level sensor 5, and a third feed level sensor 6 are respectively installed on the upper part of the first buffer bin 1, the second buffer bin 2, and the third buffer bin 3. Each feed level sensor is used to detect the material feeding level in the corresponding buffer bin. When the material reaches the preset level... When the height is set, a signal can be sent to control the further input of materials and prevent material overflow. The first buffer bin 1 is equipped with a first feeder 7 and a first vibrator 10 at the lower conical part. The second buffer bin 2 is equipped with a second feeder 8 and a second vibrator 11 at the lower conical part. The third buffer bin 3 is equipped with a third feeder 9 and a third vibrator 12 at the lower conical part. Each feeder is used to detect the material feed level of the corresponding buffer bin to ensure that the material can be discharged as needed. Each vibrator is used to vibrate the bin and provide vibration during the material discharge process to improve the material flowability.

[0022] Specifically, a first pneumatic regulating butterfly valve 13, a second pneumatic regulating butterfly valve 14, and a third pneumatic regulating butterfly valve 15 are respectively installed at the outlets of the first buffer chamber 1, the second buffer chamber 2, and the third buffer chamber 3. These pneumatic regulating butterfly valves control the material feeding speed. Preferably, the first pneumatic regulating butterfly valve 13, the second pneumatic regulating butterfly valve 14, and the third pneumatic regulating butterfly valve 15 are all automatic opening regulating valves, with two opening degrees: a large opening of 40% and a small opening of 20%. This allows for flexible adjustment of the material conveying speed according to actual needs. Precise control of the opening of the pneumatic regulating butterfly valves can prevent material breakage due to excessive pressure during conveying. Furthermore, the air supply pressure range of the first pneumatic regulating butterfly valve 13, the second pneumatic regulating butterfly valve 14, and the third pneumatic regulating butterfly valve 15 is 1.4-7.0 kgf / cm³. 2 .

[0023] Furthermore, a first screen 16, a second screen 17, and a third screen 18 are respectively installed at the inlet of the bucket elevator 19. The bucket elevator 19 is used to transport coated materials and can lift the materials from a low position to a high position for easy subsequent processing. The screens can filter out lumps or impurities in the coated materials to ensure that the materials entering the bucket elevator 19 meet the quality requirements. The first screen 16, the second screen 17, and the third screen 18 are respectively set to correspond to the outlets of the first buffer bin 1, the second buffer bin 2, and the third buffer bin 3.

[0024] To better illustrate the structural setup of each cache repository, such as Figure 2As shown, a first feeder 4 is installed on the upper part of the first buffer bin 1, a first feeder 7 and a first vibrator 10 are installed on the lower conical part of the first buffer bin 1, and a first pneumatic regulating butterfly valve 13 is installed at the outlet of the first buffer bin 1. A first screen 16 is installed at the inlet of the bucket elevator 19, and the first screen 16 is set corresponding to the outlet of the first buffer bin 1.

[0025] Simultaneously, the first vibrator 10, the second vibrator 11, and the third vibrator 12 automatically start and stop according to a set time. The use of vibrators helps to loosen materials and reduce the risk of breakage due to compression. The vibration cycle of the first vibrator 10, the second vibrator 11, and the third vibrator 12 is 30 seconds, and the duration of a single vibration is 5 seconds. Preferably, the first vibrator 10, the second vibrator 11, and the third vibrator 12 are all GT turbine vibrators. Furthermore, the air supply pressure of the first vibrator 10, the second vibrator 11, and the third vibrator 12 is 0.6 MPa, the vibration force is 5520 N, and the air consumption is 455 ml / min.

[0026] In this embodiment, the automatic feeding control system for preventing coating material breakage and filtering agglomerated materials operates by first storing the coating material in the first buffer bin 1, the second buffer bin 2, and the third buffer bin 3. After the coating machine completes the feeding of two batches of material, the coating personnel notify the central control room to start the automatic feeding program. At this time, the first pneumatic regulating butterfly valve 13, the second pneumatic regulating butterfly valve 14, and the third pneumatic regulating butterfly valve 15 automatically open, starting the material conveying process. Since the first pneumatic regulating butterfly valve 13, the second pneumatic regulating butterfly valve 14, and the third pneumatic regulating butterfly valve 15 are all automatically adjustable in opening, and have two openings, the large opening is set to 40%, mainly used to quickly release any agglomerated material to prevent it from clogging the outlet. The small opening is set to 20%, mainly used to control the material feeding speed to ensure smooth material discharge and reduce material breakage and crushing. By setting the opening and closing time of the large and small openings, these two openings will cycle through to achieve optimal material feeding. The conveying effect ensures that the bucket elevator 19 does not overfeed. When the first discharge level device 7, the second discharge level device 8, and the third discharge level device 9 detect that the material is about to be discharged, they send a signal to the control system. At this time, the first pneumatic regulating butterfly valve 13, the second pneumatic regulating butterfly valve 14, and the third pneumatic regulating butterfly valve 15 close after a delay to ensure that the material is completely discharged and to avoid idling. At the inlet of the bucket elevator 19, the first screen 16, the second screen 17, and the third screen 18 are installed respectively to effectively filter lumps and impurities in the material, ensuring that only materials that meet the quality requirements enter the next process. In order to avoid the buffer bin not discharging or discharging slowly, the first vibrator 10, the second vibrator 11, and the third vibrator 12 will automatically start and stop according to the set time. Specifically, the first vibrator 10, the second vibrator 11, and the third vibrator 12 vibrate once every 30 seconds, and each vibration lasts for 5 seconds, which helps to loosen the material and promote its smooth fall.

[0027] This utility model's automatic feeding control system for preventing coating material breakage and filtering agglomerated materials employs the coordinated control of a pneumatic regulating butterfly valve and a turbine vibrator. This automatically controls the uniform feeding of coating materials, preventing breakage and ensuring product quality. Simultaneously, the filter structure effectively intercepts abnormally agglomerated materials, ensuring continuous feeding while improving filtration accuracy. The system's automation level is significantly improved, requiring no personnel to operate, eliminating manual intervention, effectively reducing labor costs, and avoiding the risk of material breakage due to human error. This utility model features a reasonable overall structural design, is easy to use, and highly practical.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
