Description

Technical Field

[0001] This utility model relates to the field of material receiving equipment technology, and in particular to an automatic detection hopper docking device. Background Technology

[0002] Hoppers are widely used in the pharmaceutical industry. They are key equipment in the solid dosage form production process for material conveying, mixing, lifting, feeding, and intermediate storage.

[0003] In the material discharge process, the hopper is used to receive materials. The hopper is placed below the discharge device, and the discharge device is connected to the hopper through a docking device to ensure that the materials can be accurately loaded into the hopper. However, in the existing technology, it is not easy to know whether the hopper is full, and therefore it is impossible to determine when to stop the discharge device to continue discharging. Usually, the discharge device is paused manually first, and then the hopper is moved out to observe the material loading status in the hopper. This is not only cumbersome to operate, but also has low discharge efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an automatically detectable hopper docking device. This invention uses a material level switch to automatically detect whether the material in the receiving hopper is full, eliminating the tedious steps of manual inspection and improving overall production efficiency.

[0005] The technical solution adopted by this utility model is as follows: an automatically detectable hopper docking device includes a discharge device, a receiving hopper, and a docking device. The discharge device is equipped with a valve for controlling the on / off state, and also includes a control system and a frame for mounting the docking device. A space for pushing the receiving hopper in is provided below the frame. The docking device includes a docking cylinder and a telescopic drive assembly. One end of the docking cylinder is used to connect to the discharge device and the other end is used to connect to the receiving hopper. The telescopic drive assembly is used to drive the docking cylinder to extend and retract to connect with the discharge device and the receiving hopper. The end of the docking cylinder used to connect with the receiving hopper is also equipped with a level switch. The level switch is used to detect the amount of material contained in the receiving hopper in real time. The valve, the telescopic drive assembly, and the level switch are all electrically connected to the control system.

[0006] The docking cylinder includes a first docking hopper, a telescopic hose, and a second docking hopper. The first docking hopper is used to dock with the discharge device, and the second docking hopper is used to dock with the receiving hopper. The telescopic hose connects the first docking hopper and the second docking hopper. The telescopic drive assembly includes a fixed frame, a first telescopic cylinder, and a second telescopic cylinder. The fixed frame is mounted on a frame by fasteners. The first telescopic cylinder and the second telescopic cylinder are respectively mounted at both ends of the fixed frame. The first telescopic cylinder is also connected to the first docking hopper, and the second telescopic cylinder is also connected to the second docking hopper.

[0007] The material level switch is installed on the second docking hopper. When the second docking hopper docks with the receiving hopper, one end of the material level switch extends into the receiving hopper.

[0008] It also includes a filter element and a ring cover. The second docking hopper includes a straight cylindrical part and a docking plate. The diameter of the docking plate is larger than that of the straight cylindrical part. One end of the straight cylindrical part has a protruding mounting ring. The outer peripheral wall of the mounting ring is provided with an external thread for threaded connection of the ring cover. The filter element is sandwiched between the mounting ring and the ring cover.

[0009] The filter element is disc-shaped, the material level switch is mounted on the docking plate, and the filter element has a number of filter holes with decreasing inner diameters. The inner diameter of the filter holes on the side of the filter element closer to the material level switch is smaller than that on the side of the filter element farther away from the material level switch.

[0010] Both the first docking hopper and the second docking hopper are provided with sealing rings on their end faces. The second docking hopper is also provided with a sealing plug. When the second docking hopper docks with the receiving hopper, the sealing plug is embedded in the inner edge of the receiving hopper.

[0011] The valve is an automatic butterfly valve.

[0012] The beneficial effects of this utility model are as follows: By setting a material level switch at the connection end between the docking cylinder and the receiving hopper, when the material level switch detects material, it indicates that the receiving hopper is full and immediately sends a signal to the control system. The control system then automatically closes the valve on the discharge device to stop discharging. This process is fully automated, fundamentally solving the core problem of not being able to determine when to stop discharging due to reliance on manual observation and operation in the background technology. This significantly improves overall production efficiency and has a relatively low cost. It is suitable for situations where the weight accuracy requirement of the material in the docking hopper is not high. The entire detection and control process is automatically completed by the control system, reducing the labor intensity of operators and the risk of human error. The system has a high degree of integration, unifying the valve, telescopic drive component, and material level switch under the control system, realizing fully automatic docking and discharging operations, simplifying the operation process, and improving the intelligence level and operational safety of the equipment.

It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0017] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0018] like Figures 1 to 5As shown in the figure, an embodiment of the present invention is provided, which is an automatically detectable hopper docking device, including a discharge device 1, a receiving hopper 2, and a docking device. The discharge device 1 is provided with a valve for controlling the on / off state, and also includes a control system 3 and a frame 4 for mounting the docking device. The frame 4 has a space below it for the receiving hopper 2 to be pushed in. The docking device includes a docking cylinder 5 and a telescopic drive assembly 6. One end of the docking cylinder 5 is used to connect to the discharge device 1 and the other end is used to connect to the receiving hopper 2. The telescopic drive assembly 6 is used to drive the docking cylinder 5 to extend and retract to connect with the discharge device 1 and the receiving hopper 2. The end of the docking cylinder 5 used to connect to the receiving hopper 2 is also provided with a level switch 7. The level switch 7 is used to detect the amount of material contained in the receiving hopper 2 in real time. The valve, the telescopic drive assembly 6, and the level switch 7 are all electrically connected to the control system 3.

[0019] The beneficial effects of this design are as follows: By setting a material level switch at the connection end between the docking cylinder and the receiving hopper, when the material level switch detects material, it indicates that the receiving hopper is full and immediately sends a signal to the control system. The control system then automatically closes the valve on the discharge device to stop discharging. This process is fully automated, fundamentally solving the core problem of not being able to determine when to stop discharging due to reliance on manual observation and operation in the prior art. This significantly improves overall production efficiency and has a relatively low cost. It is suitable for situations where the weight accuracy requirement of the material in the docking hopper is not high. The entire detection and control process is automatically completed by the control system, reducing the labor intensity of operators and the risk of human error. The system has a high degree of integration, unifying the valve, telescopic drive component, and material level switch under the control system, realizing fully automatic docking and discharging operations, simplifying the operation process, and improving the intelligence level and operational safety of the equipment.

[0020] Further configuration: the docking cylinder 5 includes a first docking hopper 8, a telescopic hose 9, and a second docking hopper 10. The first docking hopper 8 is used to dock with the discharge device 1, and the second docking hopper 10 is used to dock with the receiving hopper 2. The telescopic hose 9 connects the first docking hopper 8 and the second docking hopper 10. The telescopic drive assembly 6 includes a fixed frame 11, a first telescopic cylinder 12, and a second telescopic cylinder 13. The fixed frame 11 is mounted on the frame 4 by fasteners. The first telescopic cylinder 12 and the second telescopic cylinder 13 are respectively mounted at both ends of the fixed frame 11. The first telescopic cylinder 12 is also connected to the first docking hopper 8, and the second telescopic cylinder 13 is also connected to the second docking hopper 10.

[0021] The beneficial effects of this design are as follows: By configuring the docking cylinder as a three-section structure consisting of a first docking hopper, a telescopic hose, and a second docking hopper, each driven independently by two pairs of telescopic cylinders, the device can flexibly adjust the position and angle of both ends, automatically compensating for alignment errors between the discharge device and the receiving hopper. This achieves a smoother and more reliable sealed connection. The telescopic hose connection not only provides the necessary freedom for the cylinder's telescopic movement but also forms a continuous sealed conveying channel, effectively preventing material leakage and dust generation during transport, which is particularly in line with the high requirements of the pharmaceutical industry for a clean production environment. Bolts, a technology already in use, are used as fasteners.

[0022] In a further configuration, the material level switch 7 is mounted on the second docking hopper 10. When the second docking hopper 10 docks with the receiving hopper 2, one end of the material level switch 7 extends into the receiving hopper 2.

[0023] The beneficial effects of this setting are as follows: The level switch, also known as the level control switch, is a sensor device used to detect whether the height of solid material in a container or storage tank has reached a specific position. It achieves level control by outputting a switch signal. Its installation methods include threaded or flanged fixed-point installation on the top, side or bottom of the silo. It is mainly used for monitoring high, low and intermediate material levels in industries such as chemical, cement, pharmaceutical, and food.

[0024] Further configuration includes a filter element 14 and a ring cover 15. The second docking hopper 10 includes a straight cylindrical portion 16 and a docking plate 17. The diameter of the docking plate 17 is larger than that of the straight cylindrical portion 16. One end of the straight cylindrical portion 16 has a protruding mounting ring 18. The outer peripheral wall of the mounting ring 18 is provided with an external thread 19 for threaded connection of the ring cover 15. The filter element 14 is sandwiched between the mounting ring 18 and the ring cover 15.

[0025] The beneficial effects of this design are as follows: the filter disc can effectively filter impurities in the material, resulting in higher material purity and better output quality. The filter disc is pressed onto the mounting ring by a threaded ring cap, forming a modular filter unit. This structure is compact, and the ring cap is located at the lower end of the second receiving hopper. The ring cap can be easily unscrewed without additional tools, enabling quick cleaning or replacement of the filter disc. When the filter disc is removed, impurities inside the second receiving hopper can also be cleaned out, greatly simplifying daily maintenance and ensuring the efficiency and reliability of continuous equipment operation.

[0026] Further configuration: the filter element 14 is disc-shaped; the material level switch 7 is mounted on the docking plate 17; the filter element 14 has a plurality of filter holes 20 arranged with decreasing inner diameters; and the inner diameter of the filter holes 20 on the side of the filter element 14 closest to the material level switch 7 is smaller than that on the side furthest from the material level switch 7.

[0027] The beneficial effects of this design are as follows: the filter holes on the filter disc are designed with decreasing inner diameters, making the filter holes near the level switch smaller. This allows the material to pass through the smaller holes and fall into the receiving hopper, preventing the material from spreading out and impacting the level switch when it falls into the receiving hopper, thus ensuring the stable operation of the level switch. The modular installation structure of the filter disc allows the filter disc to be rotated and adjusted in position. The ring cover is tightened only when the filter disc with the smallest inner diameter is located on the side closest to the level switch.

[0028] Furthermore, a sealing ring 21 is provided on the end face of both the first docking hopper 8 and the second docking hopper 10, and a sealing plug 22 is also provided on the second docking hopper 10. When the second docking hopper 10 docks with the receiving hopper 2, the sealing plug 22 is embedded in the inner edge of the receiving hopper 2.

[0029] The beneficial effects of this design are as follows: both the first and second docking hoppers are equipped with sealing rings to improve the docking seal, and the second docking hopper is also equipped with a sealing plug that can be embedded in the receiving hopper to further improve the seal between the two hoppers. The sealing plug embedded in the receiving hopper can also guide the docking direction, enabling rapid docking.

[0030] Further configuration: the valve is an automatic butterfly valve 23.

[0031] The beneficial effects of this setup are as follows: the automatic butterfly valve, in conjunction with the control system, enables automated control of material discharge.

[0032] The operating principle of this hopper docking device is as follows: After the material is prepared for discharge and the receiving hopper is placed in the space below the frame, the material level switch is installed, the docking device is started to dock with the automatic butterfly valve on the discharge device, and at the same time, it automatically seals with the receiving hopper. The automatic butterfly valve opens and discharge begins. When the material level switch detects the material, it indicates that the receiving hopper is full. Feedback is sent to the control system, which then automatically closes the automatic butterfly valve, shuts off the air source in the docking device, removes the receiving hopper, and repeats the above steps until discharge is complete.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
