Description

Technical Field

[0001] This application relates to the field of tobacco processing technology, and in particular to a design method for a tobacco shred thickness distributor that provides uniform feeding for a flavoring machine. Background Technology

[0002] Existing tobacco flavoring processes generally employ roller-type equipment. Its main characteristic is the use of rollers and rakes to disperse, mix, and tumble the tobacco pile. The spacing, height, and number of rakes affect the distribution, mixing, and tumbling of the tobacco. Furthermore, the thickness of the tobacco feed affects the uniformity and utilization rate of flavoring. The uniformity and utilization rate of the flavoring process are directly related to the tobacco feed thickness, the tumbling position, and the mixing time. Improving the uniformity of the tobacco flavoring process requires optimizing and adjusting multiple parameters (tobacco feed thickness, tumbling position, and mixing time) to meet requirements. This poses a significant challenge to on-site operators in setting these parameters appropriately to further improve the uniformity of tobacco flavoring.

[0003] As the principle of a flavoring machine shows, flavoring tobacco involves evenly spraying a prepared flavoring solution onto the tobacco shreds to be rolled. Adding appropriate amounts of tobacco flavoring to cigarette tobacco can mellow the aroma, modify the smoky flavor, and correct the taste. Therefore, the uniformity of the tobacco feeding amount is crucial for flavoring. However, existing technologies still have some problems; the tobacco feeding amount is not very uniform, resulting in uneven flavoring amount and poor aroma quality. Furthermore, the tobacco thickness distributor for even feeding in the flavoring machine needs to be designed specifically to match the machine's feeding device, and existing design methods still have shortcomings. Summary of the Invention

[0037] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0038] Implementation Column 1

[0039] Figure 4-7 The simulation diagram of the tobacco thickness distributor at the feed end of the flavoring machine designed by this method is shown.

[0040] like Figure 4-7 As shown, the design method of the tobacco thickness distributor for the flavoring machine includes the following steps:

[0041] Step 1: Measure the external dimensions of the vibrating groove 4 at the feed end of the incense machine and the box 1 at the feed end of the incense machine to obtain three-dimensional spatial cloud data of the feed end of the incense machine; specifically, use equipment scanning technology and on-site survey drawing to measure the external dimensions of the vibrating groove 4 at the feed end of the incense machine and the box 1 at the feed end of the incense machine.

[0043] Step 3: Design the tobacco thickness distributor 8 at the feeding end of the flavoring machine based on the 3D model of the feeding end of the flavoring machine.

[0044] Step 4: Based on the model results of the tobacco thickness equalizer at the feed end of the flavoring machine designed in Step 3, a simulation experiment was conducted using computer-aided design software. The computer-aided design software used in this embodiment is EDEM software.

[0045] The steps for conducting simulation experiments using computer-aided design software are as follows:

[0065] Prepare the model: Import the model using computer-aided design software, and ensure that the model's dimensions and geometry match the actual situation.

[0066] Determine material parameters: Determine the physical and mechanical properties of the tobacco to be simulated, such as density, particle shape, coefficient of friction, and elastic modulus, and input these parameters into the computer-aided design software.

[0067] Set up the simulation environment: Select the simulation environment (such as gravity field, gas medium, etc.) and set its parameters. Set the simulation time and simulation time step according to the actual situation.

[0068] Add boundary conditions: Add boundary conditions to simulate the limitations and constraints in the actual process.

[0071] Step 5: Verify the accuracy of the model by comparing simulation data, and improve the designed tobacco thickness distributor in combination with the actual production process, providing a theoretical basis for development.

[0072] The simulation data comparison includes the optimization of material distribution and the analysis of the motion trajectory of tobacco shreds on the vibrating groove 4 at the feed end of the flavoring machine.

[0073] (1) Material distribution optimization: EDEM simulation provides a detailed distribution of tobacco shreds on the vibrating trough. Multiple simulation results show that by adjusting the height of the tobacco shred thickness distributor 8, we can effectively improve the uniformity of tobacco feeding on the belt, thereby reducing accumulation and tilting phenomena and improving production efficiency.

[0074] (2) Motion trajectory analysis: The simulation results show the motion trajectory of the tobacco shreds on the vibrating groove 4 at the feed end of the flavoring machine. The flow path of the tobacco shreds on the equipment can be changed by adjusting the height of the tobacco shred thickness distributor 8. This is crucial for identifying potential blockage points or unevenly distributed areas so as to carry out further optimization and improvement.

[0075] The tobacco thickness distributor 8 is a “∧” shaped structural plate formed by two arc-shaped plates with their convex surfaces connected to each other. It is installed on the vibrating groove 4 at the feed end of the flavoring machine through an installation mechanism, with the tip of the tobacco thickness distributor 8 facing the material feeding direction.

[0076] The vibrating groove 4 at the feed end of the aroma-adding machine is provided with vibrating groove baffles 3 on both sides. The mounting mechanism includes a linear guide rail 5, a slider 6, and a connecting rod 7. The linear guide rail 5 is symmetrically and vertically installed on the vibrating groove baffles 3 on both sides of the vibrating groove 4 at the feed end of the aroma-adding machine. The slider 6 is slidably installed on the linear guide rail 5, and a positioning pin for fixing the position of the slider 6 is provided on the linear guide rail 5. The slider 6 and the outer side of the tobacco thickness distributor 8 are connected by the connecting rod 7.

[0077] The feeding end of the vibrating trough 4 at the feeding end of the aroma-adding machine is connected to the feeding port 9 of the feeding end housing 1 of the aroma-adding machine. The upper side of the feeding port 9 is a fan-shaped groove 2. The height of the tobacco thickness distributor 8 at the feeding end of the aroma-adding machine can be adjusted by adjusting the height of the slider 6 on the linear guide rail 5, thereby controlling the amount of smoke entering the vibrating trough 4 at the feeding end of the aroma-adding machine, so that the amount of smoke entering is uniform and will not cause blockage at the feeding end. When adjusted to a suitable position, the position of the slider 6 is fixed by the positioning pin set on the linear guide rail 5. The opening width of the tobacco thickness distributor 8 matches the width of the vibrating trough 4 at the feeding end of the aroma-adding machine to prevent tobacco from passing through the gap between the tobacco thickness distributor 8 and the vibrating trough baffle 3, thus ensuring the uniformity of tobacco thickness. Figure 7 It can be seen that the uniformity of the tobacco shreds has been ensured.

[0078] This application designs a tobacco thickness distributor at the feed end of a flavoring machine based on 3D modeling technology, simulation, and comparative experiments. The designed tobacco thickness distributor 8 provides a new approach to solving the problem of flavoring uniformity. Its advantages include low measurement workload, accurate measurement results, simple structure, and ease of implementation. The designed device can control the amount of smoke fed into the vibrating groove 4 at the feed end of the flavoring machine by adjusting the height of the tobacco thickness distributor 8, ensuring uniform smoke feeding without causing blockage at the feed end. Simultaneously, uniform feeding results in uniform flavoring and improves the quality of the tobacco.
