[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Traditional tobacco processing rollers are cleaned by direct spraying. However, when impurities become too stubborn inside the roller, the spraying needs to be pressurized. Since workers cannot accurately locate the stubborn stains during cleaning, the cleaning quality cannot be guaranteed. Furthermore, prolonged use of high-pressure spraying can lead to significant water waste.
[0024] In view of this, the present invention provides a cleaning device for tobacco processing drums. Through the cooperation of connecting plate, connecting pipe and cleaning mechanism, the inside of the drum can be cleaned simultaneously by spraying and brushing, thereby ensuring the overall cleaning efficiency. Stubborn stains can be removed by brushing without the need for workers to increase the spray water pressure, thus effectively avoiding unnecessary waste of water resources and improving energy efficiency.
[0025] Example 1: By Figure 1 , 2As can be seen from points 3, 4, and 5, a tobacco leaf processing drum cleaning device includes a drum 1. A connecting plate 7 is disposed inside the drum 1. A connecting pipe 8 is connected to one side of the bottom of the connecting plate 7. A support plate 3 is disposed below one side of the connecting plate 7. A controller 6 is disposed on one side of the connecting plate 7. A cleaning mechanism 2 is disposed above one side of the connecting plate 7. The cleaning mechanism 2 includes: a drive unit 21 disposed above one side of the connecting plate 7; a first vertical plate 22 disposed above one side of the connecting plate 7; a second vertical plate 23 inserted into the inner wall of the first vertical plate 22; and a torsion... Two rods 25 are provided, each threadedly connected to the upper sides of the first vertical plate 22; two clamping plates 26 are provided, each fixedly connected to the end of the two torsion rods 25, and the clamping plates 26 have a circular structure, with the outer walls of both clamping plates 26 abutting against the outer wall of the second vertical plate 23; a brushing device 24 is provided above the first vertical plate 22; wherein, the driving unit 21 drives the brushing device 24 to rotate to clean the inside of the roller 1, and when the second vertical plate 23 moves along the inside of the first vertical plate 22, it changes the position of the brushing device 24;
[0026] In the specific implementation process, it is worth noting that, in actual use, the staff needs to erect an external support or use all feasible methods to connect and fix the tobacco processing drum cleaning device to the external structure using the support plate 3 and bolts, so that the tobacco processing drum cleaning device is placed in the center of the drum 1, so as to ensure that the drive unit 21 can drive the brushing device 24 to fully contact the inner wall of the drum 1 when rotating. The specific installation measures can be selected according to the actual use requirements. This case will not be elaborated in detail here. Those skilled in the art should understand it in a broad sense. It is understood that the support plate 3 provided in this embodiment is only one possible implementation method to fix the erected support, not all embodiments. In the specific implementation process, other structures can also be used. The specific structure selection can be reasonably designed according to the actual situation. In actual use, the staff can connect the tobacco processing drum cleaning device to the external water supply device or air supply device using the connecting pipe 8, and then, after the inner wall of the drum 1 is refreshed, the inner wall of the drum 1 is quickly dried by increasing the air flow rate. Of course, Alternatively, the roller 1 can be dried by natural air drying. The specific drying method is not limited, as long as it meets the usage requirements. The connecting pipe 8, connecting plate 7, rotating pipe 211, second vertical plate 23, first vertical plate 22, sleeve plate 241, and brush 242 are all interconnected. The brush 242 has an opening at its top, allowing water to be sprayed out sequentially through each component from the opening in the brush 242. This, combined with the brush 242, enables better cleaning of the inner wall of the roller 1. It should be noted that the connecting pipe 8, connecting plate 7, rotating pipe 211, second vertical plate 23, first vertical plate 22, and sleeve plate... The connection between 241 and brush 242 should be sealed by means of installing sealing rings, etc. The specific sealing measures are not limited, as long as they meet the usage requirements. If sealing is done by installing sealing rings, the sealing rings need to be inspected and replaced regularly. When in use, the controller 6 can control the first servo motor 214, the second servo motor 54 and the electric push rod 42 to work together through signal transmission, so as to better complete the predetermined work requirements. This is the prior art, so it will not be described in detail here. Those skilled in the art should understand it in a broad sense.
[0027] Furthermore, the drive unit 21 includes: a rotating tube 211, rotatably connected to the side of the connecting plate 7 away from the connecting tube 8 via a sealed bearing; a first gear 212, fixedly connected to the outer wall of the rotating tube 211 near the connecting tube 8; a second gear 213, meshing with the outer wall of the first gear 212; and a first servo motor 214, fixedly connected to the top of the connecting plate 7, with its output end fixedly connected to one side of the outer wall of the second gear 213. The first servo motor 214 is electrically connected to the controller 6. The first servo motor 214 drives the first gear 212 to rotate the rotating tube 211 via the second gear 213.
[0028] In the specific implementation process, it is worth noting that the first servo motor 214 can drive the second gear 213 to drive the rotating tube 211 to rotate through the first gear 212, which in turn drives the brushing device 24 to rotate so as to thoroughly brush the inner wall of the roller 1.
[0029] Furthermore, the top of the connecting plate 7 is fixedly connected to an isolation box 2141 sleeved on the outside of the first servo motor 214, and the output end of the first servo motor 214 is rotatably connected to the inner wall of the isolation box 2141 through a sealed bearing.
[0030] In the specific implementation process, it is worth noting that the isolation box 2141 can isolate and protect the first servo motor 214 in order to prevent water from entering the interior of the first servo motor 214 and causing the first servo motor 214 to be short-circuited and damaged.
[0031] Furthermore, the brushing device 24 includes: a sleeve 241, sleeved on the upper outer wall of the second vertical plate 23; a brush 242, fixedly connected to the top of the sleeve 241, with the top of the brush fitting against the upper inner wall of the roller 1; and a spring 243, sleeved on the upper outer wall of the second vertical plate 23, with the top and bottom of the spring 243 respectively fixedly connected to the bottom of the sleeve 241 and the upper outer wall of the second vertical plate 23; wherein the sleeve 241 moves along the outer wall of the second vertical plate 23 and changes the shape of the spring 243.
[0032] In the specific implementation process, it is worth noting that when the spring 243 is compressed, it will cause the brush 242 to be in contact with the inner wall of the roller 1 at all times. In this way, the stubborn stains can be scrubbed by the brush 242. Furthermore, the staff needs to replace the brush 242 and the spring 243 regularly to avoid excessive wear of the brush 242 and a decrease in the elastic potential energy of the spring 243, which would lead to a reduction in the scrubbing quality.
[0033] Specifically, when using the tobacco processing drum cleaning device, the operator first twists the torsion bar 25, which drives the clamping plate 26 to move. When the clamping plate 26 leaves the outer wall of the second vertical plate 23, it changes the position of the second vertical plate 23 inside the first vertical plate 22, thereby adjusting the position of the brushing device 24. After the position of the brushing device 24 is adjusted, the clamping plate 26 is used again to clamp and limit the second vertical plate 23 and the first vertical plate 22. Then, the tobacco processing drum cleaning device is set at the center of the inside of the drum 1. At this time, the operator connects the external water supply device to the tobacco processing drum cleaning device through the connecting pipe 8. Then, the operator turns on the tobacco processing drum cleaning device. At this time, the first servo motor 214 drives the first gear 212 to rotate through the second gear 213, so as to change the rotation of the brushing device 24 through the rotating pipe 211. At the same time, the external water supply device is turned on, and the inner wall of the drum 1 can be cleaned in all directions.
[0034] Example 2: From Figure 1 , 2 As shown in section 6, a first adjustment device 4 is provided above the support plate 3. The first adjustment device 4 includes: a slide rail 44, which is fixedly connected to the top of the support plate 3; two slide plates 41, both of which are slidably engaged with the outer wall of the slide rail 44; a support plate 43, which is fixedly connected to the top of the support plate 3 on the side near the connecting plate 7; and an electric push rod 42, which is fixedly connected to the outer wall of the support plate 43 and is fixedly connected to the outer wall of the slide plate 41 on the side away from the support plate 43. The electric push rod 42 is electrically connected to the controller 6. The electric push rod 42 drives the slide plate 41 to slide along the outer wall of the slide rail 44.
[0035] In the specific implementation process, it is worth noting that multiple ball bearings are installed on the top of the support plate 43, which can reduce the friction between the support plate 43 and the first horizontal plate 51, so that the first horizontal plate 51 can move better along the top of the support plate 43. The cooperation of the slide rail 44 and the slide plate 41 can limit the position of the first horizontal plate 51, so that the first horizontal plate 51 can only achieve simple reciprocating motion.
[0036] Furthermore, a second adjustment device 5 is provided above the first adjustment device 4. The second adjustment device 5 includes: a first horizontal plate 51, fixedly connected to the top of the two sliding plates 41; a second horizontal plate 52, inserted into the inner wall of the first horizontal plate 51, and one end of which is fixedly connected to the outer wall of the connecting plate 7; a threaded rod 53, rotatably connected to the inner wall of the first horizontal plate 51 through a sealed bearing, and threadedly connected to the inner wall of the second horizontal plate 52; and a second servo motor 54, fixedly connected to the outer wall of the first horizontal plate 51 on the side away from the connecting plate 7, and fixedly connected to one end of the threaded rod 53. The second servo motor 54 is electrically connected to the controller 6. The second servo motor 54 drives the second horizontal plate 52 to move along the inner wall of the first horizontal plate 51 through the threaded rod 53.
[0037] In the specific implementation process, it is worth noting that the second servo motor 54 can change the position between the second horizontal plate 52 and the first horizontal plate 51 through the threaded rod 53, thereby changing the position of the cleaning mechanism 2.
[0038] Specifically, based on the above embodiment one, when cleaning the inner depth of the roller 1, the electric push rod 42 drives the slide plate 41 to slide along the outer wall of the slide rail 44. At this time, the position of the cleaning mechanism 2 can be changed by adjusting the position of the second adjustment device 5. Then, the second servo motor 54 drives the threaded rod 53 to rotate, and then changes the position between the second horizontal plate 52 and the first horizontal plate 51 so as to drive the cleaning mechanism 2 into the deeper part of the roller 1 for cleaning operations.
