Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, specifically to an automatic sampling and analysis system for stem fibers. Background Technology

[0002] Automated sampling and analysis equipment is an automated system that integrates sample collection with component and characteristic analysis. It can complete the entire process from sample extraction to analysis results generation according to a preset program without continuous human intervention. It is widely used in scenarios that require high-frequency, accurate, and real-time monitoring. Its core purpose is to replace the inefficient mode of traditional manual sampling and laboratory analysis, reduce human error, and improve data timeliness.

[0003] The automatic sampling and analysis equipment for tobacco stems is a specialized automated system that integrates automatic sampling and key quality indicator analysis functions for tobacco stems, a core intermediate product in the tobacco processing process. It monitors the quality status of tobacco stems in real time and accurately, ensuring that the tobacco stems meet the process requirements of cigarette production (such as taste, combustibility, filling properties, etc.), and ultimately guaranteeing the stability of cigarette product quality.

[0004] Most existing automatic stem sampling and analysis equipment still leaves 5%-15% tobacco residue after a single separation. Due to its reliance on the traditional mode of V-shaped slide and fixed negative pressure, the separation is incomplete due to factors such as fluctuations in the moisture content of the stems and the mixing of tobacco with broken stems. To meet the standards, a second manual processing is required. A 50-100g sample is taken from the stem hopper, manually screened, transferred to an independent weighing platform, weighed, and then analyzed again. This increases labor costs and reduces work efficiency. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figures 1-5 The device includes a housing 1, with a robotic arm assembly 3 installed on the inner wall of the housing 1. One end of the robotic arm assembly 3 has a vibrating groove 5, and the outlet of the vibrating groove 5 has a separating slide 6. A collecting tray 8 is placed at the bottom of the separating slide 6, and a negative pressure generator 9 is installed at one end of the separating slide 6. A collecting tray 11 is placed at the bottom of the negative pressure generator 9. Both the collecting tray 11 and the collecting tray 8 have receiving trays 13 at their bottoms. Through the arrangement of the vibrating groove 5, the separating slide 6, and the guide pipe 10, the collecting tray 8 and the collecting tray 11 process the stalks and fibers. The collected material eventually falls into the receiving tray 13, effectively replacing the cumbersome combination of manual material handling and independent weighing platform. It automatically samples and analyzes the stems and filaments, realizing the functions of automatic sampling and online metering control, thus improving the practicality of the equipment. Through the setting of the robotic arm component 3 and the vibrating groove 5, the robotic arm component 3 picks up the stem and filament mixture, and the vibrating groove 5 performs preliminary separation of the mixture. Then, the stems and filaments are extracted through the separation slide 6 and the negative pressure generator 9, enabling the equipment to automatically sample and measure in real time online, thereby improving the working efficiency of the equipment.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 A rotary cylinder 12 is installed at one end of the take-up filament tray 11 and the take-up stalk tray 8. The rotary cylinder 12 is connected to the take-up filament tray 11 and the take-up stalk tray 8. The rotary cylinder 12 drives the take-up filament tray 11 and the take-up stalk tray 8 to rotate, so that the stalk and filament fall into the receiving tray 13 respectively.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-5 One end of the robotic arm component 3 is equipped with a feeding box 4, and the lower end of the feeding box 4 is equipped with a vibrating groove 5, which effectively transmits the wire and improves the working efficiency of the equipment.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 The separation slide 6 is provided with a feed inlet 7 at one end, and the feed inlet 7 is located at the lower end of the vibrating groove 5. The filaments at the top of the vibrating groove 5 flow into the separation slide 6 through the feed inlet 7 in sequence, which improves the coordination between multiple sets of devices.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 The bottom of the separating slide 6 is open, and a collecting tray 8 is placed at the bottom of the separating slide 6. The diameter of the collecting tray 8 is larger than the diameter of the separating slide 6, which makes it easier for the collecting tray 8 to collect the stems and reduce the number of stems falling into the outer wall of the collecting tray 8.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 One end of the negative pressure generator 9 is provided with a guide pipe 10, and the bottom of the guide pipe 10 is provided with a take-up tray 11. The take-up tray 11 collects the tobacco in the guide pipe 10. The equipment automatically samples and measures in real time online.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The outer wall of the device housing 1 is provided with a movable door panel 2, and a receiving tray 13 is placed at one end of the movable door panel 2 near the device housing 1, which facilitates the removal of the receiving tray 13 and improves the working efficiency of the equipment.

[0044] Second embodiment:

[0045] Please see Figure 3 , Figure 4 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a handle 14 is added to one end of the receiving tray 13, and a fixing block is added to the other end of the receiving tray 13 to limit the position of the receiving tray 13. In addition, the handle 14 also facilitates the removal of the receiving tray 13, thereby improving the working efficiency of the equipment.

[0046] In practical operation, this utility model is as follows:

[0047] The stems separated in one step still contain a certain proportion of tobacco. The three-axis robotic arm component 3 samples the stems, and then the X and Y axes move to pour the sampled stems into the feeding hopper of the vibrating trough 5. The tobacco then enters the negative pressure generator 9 and the pressure relief component through the separation slide 6. Due to its specific gravity, the stems fall into the stem collection tray 8 along the lower end of the separation slide 6, while the tobacco enters the tobacco collection tray 11 through the pipe for weighing. The weighed stems and tobacco are then poured into the receiving tray 13 through the rotary cylinder 12. This effectively replaces the previous cumbersome combination of manual material handling and independent weighing platform, and automatically samples and analyzes the stems, realizing the functions of automatic sampling and online metering control.

[0048] Furthermore, a handle 14 is added to one end of the receiving tray 13, and a fixing block is added to the other end of the receiving tray 13 to limit the position of the receiving tray 13, thereby improving the working efficiency of the equipment and its practicality.

[0049] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
