Technical Field

[0001] This utility model belongs to the field of tobacco production technology, and specifically relates to a drum cleaning device for tobacco processing. Background Technology

[0002] In the tobacco processing industry, tobacco drying is one of the most important processes in cigarette making. Its main functions include: drying the tobacco to a moisture content suitable for rolling into cigarettes; further loosening and curling the tobacco to improve its filling capacity; the drying process volatilizes and removes some of the green and off-flavor substances, allowing the aroma of the tobacco to be revealed and improving the quality of the tobacco; and making the different ingredients in the tobacco blend more evenly.

[0003] In the current tobacco drying process, a drum dryer is usually used. During the drying process, broken tobacco leaves, stems and sticky tar components accumulate layer by layer on the inner wall of the drum. Due to the lack of effective cleaning methods, these residues continue to thicken over time, changing the heat transfer characteristics inside the drum. This makes it difficult to accurately control the drying temperature, which in turn affects the uniformity of tobacco drying and aroma quality.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] like Figures 1 to 5As shown in the figure, this utility model embodiment provides a drum cleaning device for tobacco processing, which includes a frame 1, a fixed frame 3, a vertical rod 4, a connecting plate 11, and an electric push rod 10. The fixed frame 3 is disposed at the upper end of the frame 1, and the drum 2 is located in the fixed frame. The lower end of the drum is fixed inside the upper part of the frame. A horizontally arranged support plate 5 is fixedly connected inside the lower end of the drum. The upper end of the vertical rod 4 is connected to the top of the fixed frame, and the lower end of the vertical rod is connected to the support plate 5. The vertical rod is coaxial with the drum. A spline shaft 8 is fixedly sleeved on the outside of the vertical rod. A spline hole 14 for cooperating with the spline shaft is provided at the middle position of the connecting plate 11. A first cleaning block 13 for contacting the inner wall of the drum is provided on the circumference of the connecting plate. The upper end of the electric push rod 10 is connected to the top of the fixed frame, and the lower end of the electric push rod is connected to the connecting plate.

[0033] The tobacco processing drum cleaning device provided in this embodiment of the utility model, when in use, starts the electric push rod 10, which drives the connecting plate to slide up and down along the spline shaft, so that the first cleaning block moves up and down with the connecting plate. Thus, the first cleaning block 13 can effectively clean the inner wall of the drum, making the inner wall of the drum relatively clean.

[0034] Furthermore, there are three electric push rods 10, arranged in an equilateral triangle around the vertical rod 4. This ensures the connecting disc can move smoothly up and down along the spline shaft without tilting. It is understood that the spline groove at the spline hole 14 on the connecting disc can mesh with the spline teeth on the spline shaft, thus providing good positioning and guidance for the connecting disc; the electric push rods are vertically positioned.

[0035] Specifically, the first cleaning block 13 has a ring-shaped structure. The outer circumferential surface of the first cleaning block is used to contact the inner wall of the roller, and a plurality of fixing rods 12 are evenly arranged on the circumference of the connecting disc for connecting with the inner circumferential surface of the first cleaning block. This design effectively improves cleaning efficiency by utilizing the ring-shaped first cleaning block.

[0036] Furthermore, the tobacco processing drum cleaning device also includes a second cleaning block 16. The second cleaning block has an annular structure, and its outer circumferential surface is used to contact the inner wall of the drum. The second cleaning block is located above the first cleaning block. Multiple inverted L-shaped connecting rods 15 are evenly arranged on the inner circumferential surface of the second cleaning block, and each inverted L-shaped connecting rod is connected to each of the fixed rods 12 in a one-to-one correspondence. With this design, when the electric push rod drives the connecting plate to move up and down along the spline shaft, the first and second cleaning blocks move up and down accordingly, allowing the first and second cleaning blocks to simultaneously clean the inner wall of the drum, further improving cleaning efficiency.

[0037] Preferably, both the first cleaning block 13 and the second cleaning block 16 are made of nylon. Using this design, the nylon cleaning blocks, with their relatively hard texture, can repeatedly scrape and rub off residues, especially some sticky tar residues, from the inner wall of the drum. Furthermore, the chemically stable properties of nylon prevent chemical reactions with tobacco residues or the drum's inner wall material, ensuring the safety and stability of the cleaning process. The upper end of the drum can be sealed with a sealing plate 21 to prevent air pollution during cleaning.

[0038] Furthermore, the tobacco processing drum cleaning device also includes a collection bin 20, which is disposed in the lower part of the frame, with its upper end facing the discharge port 17 of the drum. This design allows waste material removed from the inner wall of the drum to be collected in the collection bin, effectively ensuring the cleanliness of the working area.

[0039] Specifically, the tobacco processing drum cleaning device also includes a drive cylinder 18 and a moving rod 19. The drive cylinder is located on the lower part of the frame, and the cylinder rod of the drive cylinder is connected to one end of the moving rod. The other end of the moving rod is provided with a cover plate 9 for sealing the discharge port. With this design, during cleaning operations, the drive cylinder drives the moving rod to the left until the cover plate 9 seals the discharge port of the drum, preventing air pollution during cleaning. After cleaning, the drive cylinder drives the moving rod to the right, so that the cover plate no longer seals the discharge port. At this time, the waste material cleaned from the drum falls into the collection bin under gravity and is collected, achieving rapid unloading and convenient collection, maintaining the cleanliness of the work area, and preparing for the next round of tobacco processing.

[0040] In another embodiment of this utility model, a drive motor 7 is provided at the top of the fixed frame. The output shaft of the drive motor 7 passes through the fixed frame and is coaxially connected to the upper end of the vertical rod. The lower end of the vertical rod is rotatably mounted on the support plate. Limiting blocks for engaging with the connecting plate are provided at both the upper and lower ends of the splined shaft. With this design, starting the drive motor causes the vertical rod to rotate, which in turn drives the connecting plate to rotate via the splined shaft. This causes the first and second cleaning blocks to rotate with the connecting plate 11, thus cleaning the inner wall of the drum using the rotating first and second cleaning blocks. Simultaneously, the two limiting blocks effectively prevent the connecting plate from detaching from the upper and lower ends of the splined shaft. It is understood that this embodiment does not require the use of an electric push rod. By controlling the speed of the drive motor, the vertical positions of the connecting plate and the two cleaning blocks within the drum can be adjusted, thereby achieving thorough cleaning of the inner wall of the drum. The drive motor 7 can be connected to the top of the fixed frame 3 via the mounting bracket 6.

[0041] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
