Description

Technical Field

[0001] This utility model relates to the field of production sampling technology, and in particular to an online intelligent sampling machine. Background Technology

[0002] In the food, pharmaceutical, and chemical processing industries, quality control of raw materials and semi-finished products requires frequent sampling and testing to monitor material conditions in real time, such as particle size and moisture content. This allows for dynamic adjustment of production parameters (e.g., drying temperature, mixing time) to prevent batches of materials from failing quality tests. Traditional sampling methods are mostly manual, requiring operators to manually open the sampling gate of the material pipeline and directly contact the material for sampling. However, this method has the following drawbacks: 1. High risk of contamination: During the opening of the sampling gate, external contaminants such as dust and microorganisms may enter the pipeline, causing material contamination and affecting testing accuracy. 2. Operators must be in close contact with the material pipeline, especially in high-temperature, high-pressure, or hazardous material environments, which can easily lead to safety accidents. 3. Each sampling requires a dedicated operator, consuming manpower and resulting in low efficiency. Therefore, there is an urgent need for a fully automated, sealed sampling technology that reduces manual intervention and ensures operational safety to meet the quality control requirements of modern production. Utility Model Content

[0003] In view of the above situation and in order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an online intelligent sampling machine, which effectively solves the problem of inconvenience in using existing material sampling devices.

[0004] The technical solution is as follows: This utility model includes a fixed frame, on which a material pipe with a vertical axis is provided, and a conveying pipe with a horizontal axis is provided inside the material pipe. A sampling groove is opened at the upper end of the conveying pipe and located inside the material pipe. A rotatable sampling auger is coaxially provided inside the conveying pipe. A discharge pipe with a vertical axis is connected to the conveying pipe. A fixed plate is provided on the right side of the fixed frame and located below the discharge pipe. A connecting pipe is provided on the fixed plate. A flexible hose is detachably connected between the connecting pipe and the discharge pipe. A receiving plate that can move up and down is provided below the fixed plate. A control module is provided on the fixed frame in front of the material pipe.

[0005] Preferably, a servo motor is provided at the right end of the conveying pipe, and the output end of the servo motor is coaxially and fixedly connected to the sampling auger.

[0006] Preferably, both ends of the hose are connected to the connecting pipe and the discharge pipe via cable ties, respectively.

[0007] Preferably, the front and rear ends of the receiving plate are slidably connected to the fixed plate via connecting columns, the upper ends of the two connecting columns penetrate the fixed plate and are connected via a pressing column, and a cam is eccentrically provided on the pressing column.

[0008] Preferably, the cam has a handle at its right end.

[0009] Preferably, the control module is electrically connected to the servo motor.

[0010] Preferably, the lower end of the fixing plate is provided with a protective cylinder that can contact the receiving plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the device remains in a closed state throughout the entire sampling and material transfer process, the delivery pipe is nested inside the material pipeline, and the sampling slot is the only opening for material entry; the feed pipe, hose, connecting pipe and the sample container inside the protective cylinder form a continuous closed path, which effectively prevents the intrusion of external dust, microorganisms and other contaminants, ensuring the purity of the sample and the accuracy of the test. At the same time, the operator does not need to come into close contact with the material pipeline, completely avoiding the safety risks of direct operation in high temperature, high pressure or toxic and harmful environments.

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 5 The device includes a fixed frame 1, a material pipe 2 with vertical axial direction on the fixed frame 1, a conveying pipe 3 with horizontal axial direction inside the material pipe 2, a sampling slot 4 located inside the material pipe 2 at the upper end of the conveying pipe 3, a rotatable sampling auger 5 coaxially located inside the conveying pipe 3, a discharge pipe 6 with vertical axial direction connected to the conveying pipe 3, a fixed plate 7 located below the discharge pipe 6 on the right side of the fixed frame 1, a connecting pipe 8 on the fixed plate 7, a flexible hose 9 detachably connected between the connecting pipe 8 and the discharge pipe 6, a receiving plate 10 that can move up and down below the fixed plate 7, and a control module 11 located in front of the material pipe 2 on the fixed frame 1.

[0023] In order to make the sampling auger 5 rotate, a servo motor 12 is provided at the right end of the conveying pipe 3, and the output end of the servo motor 12 is coaxially and fixedly connected to the sampling auger 5.

[0024] In order to detach and connect the hose 9 to the connecting pipe 8 and the discharge pipe 6, both ends of the hose 9 are connected to the connecting pipe 8 and the discharge pipe 6 respectively via cable ties.

[0025] In order to enable the receiving plate 10 to move up and down, the front and rear ends of the receiving plate 10 are slidably connected to the fixed plate 7 via connecting columns 13. The upper ends of the two connecting columns 13 pass through the fixed plate 7 and are connected via pressing columns 14. A cam 15 is eccentrically provided on the pressing column 14.

[0026] To facilitate the rotation of the cam 15, a handle 16 is provided at the right end of the cam 15.

[0027] For ease of use, the control module 11 is electrically connected to the servo motor 12.

[0028] For ease of use, the lower end of the fixing plate 7 is provided with a protective cylinder 17 that can contact the receiving plate 10.

[0029] When this utility model is in use and sampling is required, the operator starts the servo motor 12 located at the right end of the conveying pipe 3 via the control module 11. The servo motor 12 drives the sampling auger 5, which is coaxially fixed to it, to rotate inside the conveying pipe 3. At this time, the material (such as powder, granules or slurry) in the material pipe 2 will flow into the sampling groove 4 opened at the upper end of the conveying pipe 3 due to gravity or process flow. The rotating sampling auger 5 will stably and quantitatively transport the material entering the sampling groove 4 into the conveying pipe 3. The transported material then enters the discharge pipe 6 connected to the conveying pipe 3. The discharge pipe 6 is connected to the connecting pipe 8 fixed on the lower fixing plate 7 through the flexible hose 9 fastened with cable ties at both ends, forming a closed material transfer channel. The material flows smoothly into the receiving plate 10 below by gravity through this channel.

[0030] After the sampling reaches the expected amount, the control module 11 controls the servo motor 12 to stop rotating, thereby stopping the sampling. At this time, push the handle 16 upward, and the handle 16 drives the cam 15 to rotate. Since the cam 15 is eccentrically set, it drives the receiving plate 10 to move downward, thereby driving the material falling on it to move downward. After moving downward a certain distance, the receiving plate 10 disengages from the protective cylinder 17. At this time, the operator can remove the material on the receiving plate 10 for testing.

[0031] Then press the handle 16 down again. The handle 16 drives the cam 15 to rotate in the opposite direction, which in turn drives the receiving plate 10 to move upward. After the receiving plate 10 moves upward a certain distance, it contacts the protective cylinder 17 again, forming a sealed space with the protective cylinder 17. At this time, sampling can continue.

[0032] Compared with existing technologies, the advantages of this invention are as follows: the device remains sealed throughout the entire sampling and material transfer process, with the delivery pipe nested inside the material pipeline, and the sampling slot being the only opening for material entry; the feed pipe, hose, connecting pipe, and sample container inside the protective cylinder form a continuous closed path, effectively preventing the intrusion of external dust, microorganisms, and other contaminants, ensuring the purity of the sample and the accuracy of the test. At the same time, operators do not need to be in close contact with the material pipeline, completely avoiding the safety risks of direct operation in high temperature, high pressure, or toxic and harmful environments. This structure is simple, novel in concept, easy to use, and highly practical.

[0033] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
