[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0018] Please see Figure 1-4 This application provides a technical solution: a pretreatment device for extracting nicotine from waste tobacco leaves, including a support frame 3, a cross brace plate on the support frame 3, a drive assembly 7 on the cross brace plate, and a transmission group 13 connected to the output end of the drive assembly 7. The transmission group 13 is connected to a first crushing group and a second crushing group respectively.

[0019] The support frame 3 provides mechanical support, ensuring that all components can be securely mounted on it, absorbing vibrations during equipment operation, and reducing noise and unnecessary displacement.

[0020] The cross brace plate is used to further reinforce the structure of the support frame 3 and to provide a stable mounting platform for the drive assembly 7.

[0021] The cross bracing plates are made of high-strength materials to ensure stability even under long-term operation or high load conditions.

[0022] The drive assembly 7 is typically composed of an electric motor, which is responsible for providing power by converting energy into mechanical motion through electricity or other energy forms, and then transmitting this power to the transmission assembly 13 through the output end.

[0023] The transmission group 13 is located between the drive assembly 7 and the crushing group, and plays the role of transmitting power. The transmission group 13 distributes the power from the drive assembly 7 evenly to the first crushing group and the second crushing group through the belt, ensuring that the two crushing groups work synchronously and the power distribution is reasonable.

[0024] A blower assembly is provided between the first and second crushing groups. The blower assembly includes a blower body 4, an air duct 10, a mounting bracket 8, and a fan assembly 9. The blower body 4 is a hollow cavity, with its upper end connected to the outlet of the first crushing group and its lower end connected to the inlet of the second crushing group. The air duct 10 is located on both sides of the blower body 4. The input end of the blower body 4 is connected to the output end of the fan assembly 9. The fan assembly 9 is installed in the recess of the mounting bracket 8 on the support frame 3.

[0025] The air-blowing unit is located between the first and second crushing units. It uses airflow to repeatedly crush the substandard tobacco leaves after crushing, ensuring the fineness of the material.

[0026] The main body of the hood 4 connects two material crushing groups, ensuring that the material can flow continuously in a closed environment and preventing the material from escaping.

[0027] The air duct 10 is installed on both sides of the main body 4 of the fan to guide the airflow direction generated by the fan and form an effective airflow path to facilitate air entry. The air duct 10 is set at an angle with its air outlet angle set at an upward angle to blow the tobacco leaves to the first crushing group for further crushing.

[0028] The mounting bracket 8 is designed to secure the fan assembly 9. Its recessed cavity can just accommodate the fan assembly 9. The mounting bracket 8 is firmly fixed to the support frame 3, ensuring that the fan assembly 9 remains stable during operation and that its performance is not affected by vibration or other factors.

[0029] To generate airflow, the output end of the fan assembly 9 is connected to the input end of the fan shroud body 4 through an inclined air guide duct 10; the fan assembly 9 can adjust its speed to control the airflow and adapt to the needs of different working conditions.

[0030] A filter screen plate is provided inside the main body 4 of the hood. The filter screen plate is located below the discharge port and above the air outlet of the air duct 10.

[0031] The filter screen is located below the discharge port and above the air outlet of the air duct 10; this allows the filter screen to act as a screen between the crushed waste tobacco leaves and the airflow, ensuring that only materials that meet the size requirements can continue to move downwards into the second crushing group, while larger or unsuitable particles are retained.

[0032] The filter screen has grid holes of a certain size, which only allow tobacco leaf fragments below a certain size to pass through; this ensures that the material entering the next stage of processing has a relatively uniform particle size, which is beneficial to the efficiency and quality of subsequent processes such as nicotine extraction.

[0033] Furthermore, the first material crushing group includes a first cutting cylinder 11, a tobacco leaf inlet 1, a side frame guard plate 2, and a first cutting blade group 16. The upper end of the first cutting cylinder 11 is provided with a horizontal tobacco leaf inlet 1. The side frame guard plate 2 is provided on one side of the first cutting cylinder 11 and is coaxially arranged with the first cutting blade group 16 provided inside the first cutting cylinder 11. One end of the shaft in the first cutting blade group 16 passes through the side frame guard plate 2 and is connected to the bearing seat provided on the support frame 3, and the other end is connected to the transmission group 13.

[0034] The first cutting cylinder 11 is equipped with a first cutting blade assembly 16 for preliminary cutting of waste tobacco leaves; the first cutting cylinder 11 has sufficient strength to withstand the stress during the cutting process and maintains good sealing to prevent material leakage.

[0035] The tobacco leaf feed inlet 1 is set horizontally, which facilitates the feeding operation and also prevents the material from being blown out of the first crushing group when the wind blowing group is working.

[0036] The side frame guard plate 2 is installed on one side of the first cutting cylinder 11 to provide support, which helps to balance the first cutting blade assembly 16 and reduces vibration during operation.

[0037] The first cutting blade assembly 16 consists of multiple cutting blades, which are fixed on a common shaft and work as the shaft rotates. The blades are made of wear-resistant materials to extend their service life and ensure cutting efficiency. One end of the shaft of the cutting blade assembly is connected to the transmission assembly 13 to receive power from the drive assembly 7 to cut the material.

[0038] Furthermore, the second material crushing group includes a second cutting cylinder 5 and a second cutting blade group 15. The second cutting cylinder 5 is disposed on the support frame 3, and the second cutting blade group 15 is disposed inside the second cutting cylinder 5. The shaft on the second cutting blade group 15 passes through the second cutting cylinder 5, with one end connected to the transmission group 13 and the other end connected to the bearing seat disposed on the support frame 3. A material outlet 14 is provided on one side of the second cutting cylinder 5.

[0039] Furthermore, a transmission housing 12 is provided on one side of the transmission assembly 13.

[0040] The housing 12 of the transmission component protects the transmission assembly 13 from external factors (such as dust, moisture, foreign objects, etc.), which helps to extend the service life of the transmission components and reduce wear and corrosion.

[0041] It also prevents workers from accidentally coming into contact with high-speed rotating transmission components, thereby reducing the risk of accidents and improving the safety of equipment use.

[0042] Furthermore, the lower surface of the support frame 3 is provided with a lower support foot 6.

[0043] The lower support leg 6 provides stable support for the entire pretreatment device, ensuring that the equipment will not shift due to vibration or external force during operation, thereby ensuring the stability of the processing.

[0044] Furthermore, the lower support leg 6 is adjustable, allowing operators to adjust the height according to ground conditions to ensure that the support frame 3 and all its components are level.

[0045] Furthermore, the second cutting cylinder 5 is also equipped with an auxiliary heating unit.

[0046] Furthermore, the auxiliary heating assembly includes an outer sleeve 17 and a heating component 18, the heating component 18 being attached to the outside of the second cutting cylinder 5, and the outer sleeve 17 being installed on the outside of the heating component 18.

[0047] The heating component 18 is attached to the outside of the second cutting cylinder 5 and is used to transfer heat into the cylinder. The heating component 18 can adjust the temperature as needed to soften the tobacco leaves entering the second crushing group, reduce their hardness, thereby reducing the workload of the cutting group and ensuring a more uniform and finer crushing effect.

[0048] The outer sleeve 17 serves to protect and insulate the heating component 18. It not only prevents the external environment from affecting the heating component 18, such as dust or moisture, but also reduces heat loss to the surrounding environment, thereby improving the efficiency of heat utilization.

[0049] During use: Adjust the height of the lower support leg 6 according to the ground conditions to ensure that the support frame 3 and all its components are in a horizontal state to ensure the stability of the equipment during operation; prepare the waste tobacco leaves to be processed, and add the waste tobacco leaves evenly into the system through the tobacco leaf inlet 1 of the first crushing group. At this time, the drive component 7 is started, and the power will be transmitted to the first crushing group and the second crushing group in sequence through the transmission group 13 to start them running. The first crushing group crushes the waste material. A portion of the qualified material passes through the filter screen plate, while the unqualified material remains above the filter screen plate. At this time, the fan component 9 is started to establish a stable airflow environment to blow the unqualified material to the first crushing group for multiple cutting to improve the utilization rate of the material. At the same time, it also avoids the grid holes on the filter screen plate from being blocked and increases the feeding speed. The material entering the second crushing group is further crushed on one hand, and on the other hand, the second crushing group also plays the role of conveying the material. Its right end is provided with a material outlet 14 for outputting the material.

[0050] After the material enters the second crushing group, the heating component 18 is activated; heating the material in the second crushing group helps to soften the tobacco material that is about to enter the second crushing group, reduce cutting resistance, and further improve the fineness of the material.

[0051] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
