Description

Technical Field

[0001] This utility model relates to the field of tobacco powder extraction technology, specifically to a fully automatic tobacco powder quantitative sampling device. Background Technology

[0002] The analysis of aroma compounds in tobacco requires prior extraction. Since most aroma compounds are present in very low concentrations, each step of the extraction process is crucial and directly affects the accuracy and completeness of the qualitative and quantitative analysis of the analytes in instrumental chemical analysis.

[0003] Tobacco extraction is a solid-liquid extraction process, and the key lies in preparing the sample solution. This requires weighing a specific amount of tobacco powder, adding the extractant, and then filtering the extract after shaking. Only then can chemical analysis be performed. Current analysis mainly relies on manual sampling and extraction, which is labor-intensive, inefficient, and prone to errors. Therefore, intelligent machinery is gradually being put into use. For example, patent CN117091890A, entitled "An Automatic Sampling and Liquid Preparation Experimental Platform for Tobacco Extraction," features separate areas for conical flasks, test liquid bottles, caps, waste disposal, a shaker, a weighing device, a syringe, a filter, and a sampler. A robotic arm moves between these areas to perform processes such as bottle movement, cap removal, powder addition, liquid addition, shaking, cap tightening, liquid extraction and filtration, and waste disposal. The comparison documents show that all the mechanisms must be arranged on the same plane to facilitate the smooth operation of the robotic arm, which results in a large footprint or low processing capacity for the entire equipment. Furthermore, the previous process must be completed before the next process can begin, or additional robotic arms and weighing devices are required, which greatly increases the overall cost of the equipment. Moreover, the need for a corresponding barcode scanning mechanism to scan the codes of the sampler, conical flask, and test liquid bottle for matching is quite troublesome.

[0004] Therefore, the research objective of this utility model is to design a fully automatic quantitative tobacco powder sampling device that can perform processes such as bottle movement, cap removal, powder addition, liquid addition, and capping without the need for a robotic arm, and effectively improve the efficiency of tobacco powder sampling. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the present invention provides a fully automatic tobacco powder quantitative sampling device, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A fully automated tobacco powder quantitative sampling device, comprising:

[0008] A transmission mechanism used to transfer vials one by one;

[0009] A rotating mechanism is used to receive vials and cooperate with a corresponding clamping mechanism to fix and drive the vials to rotate. The circumference of the rotating mechanism is provided with a capping station, a weighing station, and a liquid dispensing station in sequence along the rotation direction. A material dispensing station is also provided above the weighing station.

[0010] The weighing device is movable up and down and installed on the weighing station; when the vial is rotated to the weighing station, the weighing device moves up to support the vial and weigh the material inside the vial.

[0011] The feeding mechanism includes multiple samplers that can be moved one by one to the top of the weighing device;

[0012] The capping mechanism, in conjunction with the clamping mechanism, is used to unscrew the bottle cap. When the vial rotates to the capping station, another clamping mechanism can clamp the vial at the discharge end of the conveying mechanism.

[0013] The liquid discharge mechanism is installed on the rear side of the weighing device.

[0014] The transmission mechanism includes a receiving turntable driven to rotate by a corresponding first motor, and a conveyor belt disposed at the discharge port of the receiving turntable. Both the receiving turntable and the conveyor belt are provided with corresponding guard edges. The receiving turntable forms a guiding channel with a gradually decreasing width from the middle to the discharge port through the cooperation of corresponding arc-shaped guide plates and guard edges. The spacing between the guard edges on the conveyor belt allows only one extraction bottle to pass through.

[0015] The rotating mechanism includes a rotating platform driven to rotate at the discharge end of the conveyor belt by a corresponding second motor. A fixed platform with a diameter larger than the rotating platform is coaxially arranged below the rotating platform. Corresponding protrusions are fixedly installed on the circumferences of both the fixed platform and the rotating platform.

[0016] The weighing device can be moved up and down and installed on the fixed platform; the rotating platform is provided with a number of clamping mechanisms that rotate with it, and the circumference of the clamping mechanism is provided with a corresponding embedding groove. When the rotating platform rotates to the unloading mechanism, the weighing device moves upward to unload and weigh the material through the embedding groove.

[0017] The feeding mechanism is installed above the conveying mechanism via a corresponding transverse partition, and the transverse partition has a corresponding through hole located above the weighing device.

[0018] The feeding mechanism includes samplers that move sequentially driven by a corresponding displacement mechanism. Each sampler includes a hopper fixedly installed on the displacement mechanism and a screw feeder fitted inside the hopper. A lifting assembly for raising and rotating the screw feeder is also provided on the transverse partition. The screw feeder is driven by the lifting assembly to discharge the powder from the end outlet of the hopper to the extraction bottle placed on the weighing device.

[0019] Each displacement mechanism includes multiple gears rotatably mounted on the transverse partition, and one of the gears is fixedly mounted on the output shaft end of the rotary motor; the displacement mechanism also includes a kit for mounting the sampler, and adjacent kits are rotatably connected by corresponding hinge shafts and meshing with the gears. The rotary motor drives the gears to rotate, which in turn drives the S-shaped kits to be transferred one by one, thereby driving the sampler to be transferred one by one to the weighing device.

[0020] The lifting and swivel assembly includes a lifting cylinder and a rotating motor fixedly installed at the piston rod end of the lifting cylinder. The output shaft end of the rotating motor is connected to a corresponding air expansion shaft. Before feeding, the rotating motor moves downward under the drive of the lifting cylinder, so that the air expansion shaft is inserted into the feed end of the screw feeder, and the air expansion shaft is inflated and fixedly connected to the screw feeder.

[0021] The clamping mechanism consists of two clamping arms that move toward or away from each other, driven by a telescopic cylinder.

[0022] The capping mechanism is a rotary electric gripper, which is moved up and down and rotated by a corresponding lifting mechanism. The lifting mechanism includes a cantilever for fixing the capping mechanism. The cantilever is fixedly mounted on the slider of the lifting assembly, and the lifting assembly is fixedly mounted on the turntable of the rotating assembly. The liquid dispensing mechanism is a liquid guide tube fixedly mounted on the cantilever, and the liquid guide tube is connected to the liquid source. After the rotating assembly drives the capping mechanism to move into position, the liquid dispensing mechanism is directly facing the extraction bottle with the cap unscrewed.

[0023] Advantages of this utility model:

[0024] 1) This utility model, through the cooperation of a transmission mechanism and a rotation mechanism that can transmit one by one, and the reasonable layout of the clamping mechanism, the feeding mechanism, the liquid feeding mechanism and the weighing device, enables the clamping, capping, powder weighing and liquid feeding of different extraction bottles at the same time, thereby effectively improving the processing efficiency.

[0025] 2) The transmission mechanism of this utility model realizes the one-by-one transmission of extraction bottles through the cooperation of the receiving turntable and the guard edge. Then, the rotating platform and the clamping mechanism of the rotating mechanism are used to fix the extraction bottles and rotate and change their positions at the same time. Thus, different extraction bottles can be clamped, capped, weighed, and discharged in a continuous flow at the same time. The embedded groove of the rotating platform of the rotating mechanism and the protruding edge of the fixed platform cooperate with each other. After the vials are transferred one by one by the transmission mechanism, they are embedded into the embedded groove and clamped and fixed by the clamping mechanism. They rotate with the rotating platform. When they rotate to the weighing device, the embedded groove makes corresponding clearance, which facilitates the weighing device to move up to receive the vials and weigh the materials. The cooperation of the rotating platform and the embedded groove makes the transmission, weighing and discharge seamlessly connected, eliminating the need for a robotic arm to clamp and move them. This is much more cost-effective than expensive robotic arm equipment.

[0026] 3) This utility model improves the arrangement and feeding method of the samplers by using hinge shafts to connect the corresponding kits to form a chain, and then the samplers are fitted onto the corresponding kits. The hinged kits are driven by gear meshing to realize the sequential transmission and replacement of samplers, thereby improving the practical effect of this utility model.

[0027] 4) This utility model utilizes a lifting and rotating assembly formed by a lifting cylinder, a rotating motor, and an air shaft to drive the screw feeder of the sampler to move and achieve material feeding. The air shaft is inserted into the screw feeder and inflated to fix the screw feeder. Then, the rotating motor drives the screw feeder to rotate in the opposite direction, and the lifting cylinder drives it to rise upward, so that a gap is formed between the screw feeder and the hopper. This allows the material in the screw feeder to be discharged from the end outlet of the hopper to the extraction bottle through the gap. The driving method is simple and convenient, further improving the practical effect of this utility model. Attached Figure Description

[0035] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0036] refer to Figure 1-6 A fully automated tobacco powder quantitative sampling device, comprising:

[0037] Transmission mechanism 1 is used to transfer vials one by one;

[0038] The rotating mechanism 2 is used to receive vials and cooperates with the corresponding clamping mechanism 3 to fix and drive the vials to rotate. The circumference of the rotating mechanism 2 is arranged with a capping station, a weighing station, and a liquid dispensing station in sequence along the rotation direction. A material dispensing station is also arranged above the weighing station.

[0039] Weighing device 4 is movable up and down and installed on the weighing station; when the vial is rotated to the weighing station, the weighing device 4 moves up to support the vial and weighs the material inside the vial.

[0040] The feeding mechanism 5 includes multiple samplers 501 that can be moved one by one to the top of the weighing device 4;

[0041] The capping mechanism 6, in conjunction with the clamping mechanism 3, is used to unscrew the bottle cap. When the vial rotates to the capping station, another clamping mechanism 3 can clamp the vial at the discharge end of the conveying mechanism 1.

[0042] The liquid discharge mechanism 7 is installed on the rear side of the weighing device 4.

[0043] This utility model, through the cooperation of the sequentially transfer mechanism 1 and the rotating mechanism 2, and the reasonable layout of the clamping mechanism 3, the feeding mechanism 5, the liquid dispensing mechanism 7 and the weighing device 4, enables the simultaneous clamping, capping, powder weighing and liquid dispensing of different extraction bottles, thereby effectively improving processing efficiency.

[0044] The transmission mechanism 1 includes a receiving turntable 101 driven to rotate by a corresponding first motor, and a conveyor belt 102 disposed at the discharge port of the receiving turntable 101. Both the receiving turntable 101 and the conveyor belt 102 are provided with corresponding guard edges 103. The receiving turntable 101 forms a guiding channel with a gradually decreasing width from the middle to the discharge port through the cooperation of corresponding arc-shaped guide plates 104 and guard edges 103. The spacing of the guard edges 103 on the conveyor belt 102 is only enough for one extraction bottle to pass through.

[0045] The rotating mechanism 2 includes a rotating platform 201 driven to rotate at the discharge end of the conveyor belt 102 by a corresponding second motor. A fixed platform 202 with a diameter larger than the rotating platform 201 is coaxially arranged below the rotating platform 201. Corresponding protrusions 203 are fixedly installed on the circumference of both the fixed platform 202 and the rotating platform 201.

[0046] The transmission mechanism 1 of this invention uses a receiving turntable 101 and a guard edge 103 to transmit extraction bottles one by one. Then, the rotating platform 201 of the rotating mechanism 2 and the clamping mechanism 3 work together to fix the extraction bottles while rotating and repositioning them. This allows for simultaneous, continuous clamping, cap removal, powder weighing, and liquid dispensing of different extraction bottles. Furthermore, the embedded groove 2011 of the rotating platform 201 and the protruding edge 203 of the fixing platform 202 cooperate with each other. The rotating platform 201 of this invention is equipped with... The corresponding embedding slot 2011 is used to transfer vials one by one through the transmission mechanism 1 and embed them into the embedding slot 2011. After being clamped and fixed by the clamping mechanism 3, the vials rotate with the rotating platform 201. When they rotate onto the weighing device 4, the embedding slot 2011 makes corresponding clearance, which facilitates the weighing device 4 to move up to receive the vials and weigh the materials. Furthermore, the cooperation between the rotating platform 201 and the embedding slot 2011 makes the transmission, weighing and unloading process seamlessly connected, eliminating the need for a robotic arm to clamp and move the vials. This makes the cost of relatively expensive robotic arm equipment much lower.

[0047] The weighing device 4 can be moved up and down and installed on the fixed platform 202; the rotating platform 201 is provided with a number of clamping mechanisms 3 that rotate with it, and the circumference of the clamping mechanism 3 is provided with a corresponding embedding groove 2011. When the rotating platform 201 rotates to the unloading mechanism 5, the weighing device 4 moves upward to unload and weigh the material through the embedding groove 2011.

[0048] The feeding mechanism 5 is installed above the transmission mechanism 1 via a corresponding transverse partition 8, and a corresponding through hole 801 is provided on the transverse partition 8 above the weighing device 4.

[0049] The feeding mechanism 5 includes a sampler 501 that moves sequentially driven by a corresponding displacement mechanism 9. The sampler 501 includes a hopper 5011 fixedly installed on the displacement mechanism 9 and a screw feeder 5012 sleeved in the hopper 5011. The transverse partition 8 is also provided with a lifting assembly 502 for lifting upward and rotating the screw feeder 5012 in the opposite direction. The lifting assembly 502 drives the screw feeder 5012 so that the powder is discharged from the end outlet of the hopper 5011 into the extraction bottle placed on the weighing device 4.

[0050] Each displacement mechanism 9 includes multiple gears 901 rotatably mounted on the transverse partition 8, and one of the gears 901 is fixedly mounted on the output shaft end of the rotary motor 902; the displacement mechanism 9 also includes a kit 903 for mounting the sampler 501, and adjacent kits 903 are rotatably connected to each other through corresponding hinge shafts 9031 and meshing with the gears 901. The rotary motor 902 drives the gears 901 to rotate, thereby driving the S-shaped kits 903 to be transferred one by one, and thus driving the sampler 501 to be transferred one by one to the weighing device 4.

[0051] This utility model improves the arrangement and feeding method of the sampler 501 by using a hinge shaft 9031 to connect the corresponding kit 903 to form a chain, and then fitting the sampler 501 onto the corresponding kit 903. The chain-like kit 903 is driven by the meshing of gear 901 to realize the sequential transmission and replacement of the sampler 501, thereby improving the practical effect of this utility model.

[0052] The lifting and swivel assembly 502 includes a lifting cylinder 5021 and a rotating motor 5023 fixedly installed at the piston rod end of the lifting cylinder 5021. The output shaft end of the rotating motor 5023 is connected to a corresponding air expansion shaft 5022. Before feeding, the rotating motor 5023 moves downward under the drive of the lifting cylinder 5021, so that the air expansion shaft 5022 is inserted into the feed end of the screw feeder 5012, and the air expansion shaft 5022 is inflated and fixedly connected to the screw feeder 5012.

[0053] This invention utilizes a lifting and rotating assembly formed by a lifting cylinder 5021, a rotating motor 5023, and an air shaft 5022 to drive the screw feeder 5012 of the sampler 501 to move and discharge material. The air shaft 5022 is inserted into the screw feeder 5012 and inflated to fix it in place. The rotating motor 5023 drives the screw feeder 5012 to rotate in the opposite direction, and the lifting cylinder 5021 drives it to rise upward, creating a gap between the screw feeder 5012 and the hopper 5011. This allows the material in the screw feeder 5012 to pass through the gap from the end outlet of the hopper 5011 onto the extraction bottle. The driving method is simple and convenient, further improving the practical effect of this invention.

[0054] The clamping mechanism 3 consists of two clamping arms 302 that move toward or away from each other, driven by a telescopic cylinder 301.

[0055] The capping mechanism 6 is a rotary electric gripper. The electric gripper is moved up and down and rotated by a corresponding lifting mechanism 12. The lifting mechanism 12 includes a cantilever 1001 for fixing the capping mechanism 6. The cantilever 1001 is fixedly mounted on the slider of the lifting assembly 1002, and the lifting assembly 1002 is fixedly mounted on the turntable of the rotating assembly 1003. The liquid dispensing mechanism 7 is fixedly mounted on the cantilever 1001. After the rotating assembly 1003 drives the capping mechanism 6 to move into place, the liquid dispensing mechanism 7 is facing the extraction bottle with the cap unscrewed.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
