Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a cleaning device for tobacco transfer boxes. Background Technology

[0002] During the tobacco processing, a tobacco transfer box is used to temporarily store the tobacco. When the tobacco is needed later, the entire tobacco transfer box is lifted and flipped by a lifting and flipping mechanism, so that the tobacco temporarily stored in the tobacco transfer box can be flipped and dumped to the required position. However, during the flipping and dumping of the tobacco, a small amount of tobacco will accumulate in some corners on the outer perimeter of the tobacco transfer box. Therefore, it is necessary to manually clean the tobacco accumulated in the corners.

[0003] However, due to the use of manual cleaning methods, it is easy to not completely clean the tobacco in every corner, resulting in insufficient cleaning and waste of tobacco. In addition, manual cleaning is time-consuming and labor-intensive, resulting in low cleaning efficiency. Furthermore, since the tobacco is manually collected during the cleaning process, it is easy to have incomplete collection, which also leads to waste of tobacco.

[0004] To address the above problems, there is an urgent need for a tobacco transfer box cleaning device. Utility Model Content

[0042] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0043] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment proposes a tobacco transfer box cleaning device. This device can automatically clean the tobacco accumulated in various corners around the outer perimeter of the tobacco transfer box, ensuring that there is no tobacco accumulation in any corner, thus guaranteeing cleaning effectiveness, avoiding tobacco waste, and improving tobacco utilization. Furthermore, it ensures that the tobacco transfer box will not carry the accumulated tobacco to other work locations during subsequent use, maintaining cleanliness and precision throughout the tobacco processing process. Simultaneously, the automatic cleaning of tobacco using this device saves time and effort, ensuring high cleaning efficiency for accumulated tobacco. It also enables targeted collection and management of the cleaned tobacco.

[0045] It is worth noting that, during the process of flipping the entire tobacco transfer box to empty the tobacco, a small amount of tobacco may accumulate in some corners around the outer perimeter of the tobacco transfer box; therefore, the tobacco transfer box involved in this embodiment specifically refers to the empty tobacco transfer box after the tobacco has been flipped and emptied.

[0046] Specifically, such as Figures 1 to 3 As shown, the tobacco transfer box cleaning device includes a first cleaning component 1, a second cleaning component 2, a dust collection hood 3, a negative pressure dust removal component, and a guide component. The first cleaning component 1 extends along the X-axis and is used to clean the tobacco transfer box along the X-axis. The second cleaning component 2 extends along the Y-axis, meaning that the first cleaning component 1 and the second cleaning component 2 are independently arranged and do not interfere with each other. The second cleaning component 2 is used to clean the tobacco transfer box along the Y-axis. Both the first cleaning component 1 and the second cleaning component 2 are covered with a dust collection hood 3, which is used to collect the tobacco cleaned by the first cleaning component 1 and the second cleaning component 2. The negative pressure dust removal component is connected to the dust collection hood 3 and is used to provide negative pressure to discharge the tobacco inside the dust collection hood 3 in a preset direction. Both the first cleaning component 1 and the second cleaning component 2 are equipped with guide components, which are used to guide the tobacco transfer box to enter the first cleaning component 1 or the second cleaning component 2 in a centered position.

[0047] Compared to existing technologies, the tobacco transfer box cleaning device in this embodiment changes the cleaning method and specific cleaning structure of the tobacco transfer box. By having the first cleaning component 1 clean the tobacco shreds at the corners of the outer periphery of the tobacco transfer box along the X-axis, and simultaneously having the second cleaning component 2 clean the tobacco shreds at the corners of the outer periphery of the tobacco transfer box along the Y-axis, the tobacco shreds cleaned by both components fall into the dust collection hood 3. Then, a negative pressure dust collector provides negative pressure to discharge the tobacco shreds in the dust collection hood 3 in a predetermined direction, thereby achieving directional cleaning of the tobacco shreds. By cleaning the tobacco transfer box in both the X and Y axes, complete cleaning of the tobacco shreds in all corners of the outer periphery of the tobacco transfer box can be ensured, resulting in a more thorough cleaning effect and preventing incomplete cleaning. This addresses the issue of wasted tobacco, thereby improving the utilization rate of tobacco. Furthermore, the automatic cleaning method saves time and labor, increasing cleaning efficiency. Simultaneously, by using a negative pressure dust collector and dust collection hood 3 working in tandem, the cleaned tobacco can be directionally discharged, facilitating unified collection and management and preventing waste due to incomplete manual collection, thus further improving tobacco utilization. Additionally, the guide component ensures the tobacco transfer box is centrally positioned within the first or second cleaning assembly 1, guaranteeing a more effective cleaning of the transfer box.

[0048] Specifically, the negative pressure dust collector can be a pump, which provides negative pressure to the dust collection hood 3 to discharge the tobacco shreds. The dust collection hood 3 and the negative pressure dust collector are connected by a negative pressure dust collection duct 4, which allows the tobacco shreds inside the dust collection hood 3 to be discharged in a specific direction. A receiving tray is provided at the outlet of the negative pressure dust collection duct 4 to collect the discharged tobacco shreds and prevent waste. The aforementioned preset direction refers to the direction in which the tobacco shreds are directed to fall into the receiving tray.

[0049] Furthermore, the tobacco transfer box cleaning device also includes a conveying mechanism and a reversing mechanism; wherein, the first cleaning component 1 and / or the second cleaning component 2 are respectively provided with a conveying mechanism, which is used to convey the tobacco transfer box along the X-axis or Y-axis, so that the tobacco transfer box can be conveyed along the X-axis to the first cleaning component 1 or along the Y-axis to the second cleaning component 2, so that the first cleaning component 1 and the second cleaning component 2 can clean the outer periphery of the tobacco transfer box respectively; the reversing mechanism is located between the first cleaning component 1 and the second cleaning component 2, and the reversing mechanism is used to pick up and switch the tobacco transfer box between the first cleaning component 1 and the second cleaning component 2; for example, after the first cleaning component 1 has finished cleaning the tobacco transfer box, the reversing mechanism can be used to remove the cleaned tobacco transfer box from the first cleaning component 1 and place it directly at the second cleaning component 2 for cleaning.

[0050] By setting up a conveying mechanism and a reversing mechanism that work together, the flexibility of the cleaning sequence for the tobacco transfer box can be improved. That is, the tobacco transfer box can be cleaned first by the first cleaning component 1 and then by the second cleaning component 2, or vice versa. The specific cleaning sequence for the tobacco transfer box is not specifically limited here and needs to be determined based on the specific layout of the conveying mechanism and the actual cleaning requirements.

[0051] Specifically, the conveying mechanism can be a conveyor belt structure, that is, the tobacco transfer box is first transported to the first cleaning component 1 or the second cleaning component 2 by the conveyor belt structure; then, the conveyor belt structure stops transporting the tobacco transfer box, that is, the entire tobacco transfer box remains stationary during the cleaning process to ensure the cleaning stability of the tobacco transfer box; and the reversing mechanism can adopt the six-axis robot structure or other reversing structures commonly used in the prior art. Here, the specific structural type of the reversing mechanism is not limited.

[0052] It is worth noting that the specific arrangement of the conveying mechanism, the reversing mechanism, the first cleaning component 1 and the second cleaning component 2 is not limited, as long as it can be ensured that the conveying mechanism, the reversing mechanism, the first cleaning component 1 and the second cleaning component 2 do not interfere with each other while performing their respective functions.

[0053] Since the structure of the first cleaning component 1 and the structure of the second cleaning component 2 in this embodiment are basically the same, the following only describes the structure of the first cleaning component 1 in detail. The second cleaning component 2 can refer to the following description of the structure of the first cleaning component 1. When describing the second cleaning component 2, the X-axis mentioned in the description of the first cleaning component 1 should be replaced with the Y-axis for corresponding explanation.

[0054] The first cleaning component 1 is described in detail below:

[0055] Specifically, such as Figures 1 to 3 As shown, the first cleaning assembly 1 includes a support frame 11, brush rollers 12, and a drive unit 13. The support frame 11 extends along the X-axis. Brush rollers 12 are detachably connected to opposite sides of the support frame 11 along the Y-axis, and several brush rollers 12 are arranged sequentially along the X-axis on each side of the support frame 11. The drive unit 13 is located on the support frame 11 and drives the brush rollers 12 to rotate around the Z-axis, so that the rotation of the brush rollers 12 can directly brush away the tobacco shreds on the tobacco transfer box. In this embodiment, the drive unit 13 can specifically be a motor.

[0056] By detachably connecting brush rollers 12 to opposite sides of the support frame 11 along the Y-axis, it is easy to replace a damaged individual brush roller 12 without having to disassemble and replace all the brush rollers 12. This makes the maintenance and replacement of the brush rollers 12 simpler and more convenient, reducing the maintenance cost of the brush rollers 12.

[0057] Furthermore, the linear velocity direction of the tangent point on the brush roller 12 that is tangent to the tobacco transfer box is opposite to the moving direction of the tobacco transfer box, so that the tobacco on the tobacco transfer box can be brushed off by the reverse rotation of the brush roller 12 relative to the tobacco transfer box, thereby ensuring that the brush roller 12 has a better brushing effect on the tobacco.

[0058] Specifically, the first cleaning component 1 also includes a through-beam sensor, which is disposed on the support frame 11. The through-beam sensor is used to sense whether the tobacco transfer box has moved between the brush rollers 12 on both sides. That is, the through-beam sensor can sense whether the tobacco transfer box has moved to the preset cleaning position, and the through-beam sensor is communicatively connected to the drive component 13. The specific placement of the through-beam sensor on the support frame 11 is not limited, as long as it can sense whether the tobacco transfer box has moved to the preset cleaning position.

[0059] Specifically, when the through-beam sensor detects that the conveying mechanism has moved the tobacco transfer box along the X-axis to between the brush rollers 12 on both sides, that is, when the tobacco transfer box has reached the preset cleaning position corresponding to the first cleaning component 1, the through-beam sensor transmits the result of sensing the position to the drive component 13, so that the drive component 13 starts to drive the brush rollers 12 to rotate to brush off the tobacco on the outer periphery of the tobacco transfer box.

[0060] By setting up a photoelectric sensor and a drive unit 13 that work together, the automatic identification function of the tobacco transfer box can be realized. That is, when the tobacco transfer box reaches the preset cleaning position, the drive unit 13 starts to work to clean the tobacco; when the tobacco transfer box does not reach the preset cleaning position, the drive unit 13 does not run, thereby avoiding resource waste.

[0061] Furthermore, such as Figure 2 and Figure 3 As shown, the support frame 11 includes multiple aluminum profile components, multiple aluminum profile corner pieces, and multiple support columns 112. The aluminum profile components can be spliced ​​together to form a frame 111. Aluminum profile corner pieces are detachably connected to each splicing corner of the aluminum profile components. Multiple support columns 112 are connected to the bottom of the frame 111 to support the frame 111 and the aluminum profile corner pieces. The bottom of each support column 112 is fixedly connected to the ground using expansion bolts.

[0062] By setting up the support frame 11 with the above-mentioned structure, on the one hand, the structural strength of the entire support frame 11 can be guaranteed, thereby ensuring the stability of the support frame 11 in supporting the drive component 13, the through-beam sensor, and each brush roller 12; on the other hand, the frame component 111 is formed by splicing the various aluminum profile components together, which facilitates the transportation of smaller aluminum profile components, thereby avoiding the transportation of larger frame components 111, thus reducing the transportation cost of the entire tobacco transfer box cleaning device; furthermore, aluminum profile corner pieces can be detachably connected at each splicing corner of each aluminum profile component, which facilitates the replacement of damaged individual aluminum profile corner pieces without dismantling the entire support frame 11, making the maintenance and replacement of the support frame 11 simpler and more convenient, and reducing the maintenance cost of the support frame 11.

[0063] Specifically, such as Figure 3 As shown, at least four brush rollers 12 are provided, with any two brush rollers 12 arranged opposite each other along the Y-axis. This ensures a good cleaning effect on the tobacco transfer box by simultaneously passing through each brush roller 12. A driving element 13 is used to drive two brush rollers 12 located on the same side to rotate around the Z-axis. That is, each brush roller 12 located on the same side of the support frame 11 is driven by the same driving element 13. This reduces the number of driving elements 13, thereby lowering the driving cost of the brush rollers 12, while ensuring that each brush roller 12 on the same side can rotate synchronously, thus ensuring a better cleaning effect on the tobacco transfer box. In this embodiment, a total of four brush rollers 12 and two driving elements 13 are provided.

[0064] It is worth noting that, since the two driving members 13 on opposite sides of the support frame 11 can be driven synchronously, the synchronous rotation of each brush roller 12 on opposite sides of the support frame 11 can be guaranteed, that is, all the brush rollers 12 on the support frame 11 can be rotated synchronously.

[0065] Specifically, such as Figure 3 As shown, the brush roller 12 includes a roller shaft 121 and several filament bundles 122. The length of the roller shaft 121 extends along the Z-axis, and several filament bundles 122 are circumferentially connected on the outer circumferential surface of the roller shaft 121. The length of the filament bundles 122 extends radially along the roller shaft 121. The driving member 13 is drivenly connected to the roller shaft 121 to drive the roller shaft 121 to rotate around the Z-axis, thereby driving the several filament bundles 122 to rotate around the Z-axis, and then cleaning the tobacco transfer box through the several rotating filament bundles 122.

[0066] Furthermore, the filament bundle 122 of the brush roller 12 is 140mm-160mm long, which allows the filament bundle 122 to be longer, enabling it to be closer to the tobacco transfer box. Even if the tobacco transfer box is slightly offset from the center of the brush rollers 12 on both sides, the longer filament bundle 122 of the brush roller 12 can still contact the tobacco transfer box, facilitating cleaning of the tobacco transfer box. In other words, the brush roller 12 with a longer filament bundle 122 can compensate for the problem of poor centering of the tobacco transfer box. In this embodiment, the filament bundle 122 of the brush roller 12 is 150mm long.

[0067] Specifically, the rotational speed of the brush roller 12 is 49 rpm-53 rpm to ensure that the rotational speed of the brush roller 12 is suitable and that the rotational speed of the brush roller 12 is not too high or too low, which would affect the cleaning effect of the brush roller 12 on the tobacco transfer box. In this embodiment, the rotational speed of the brush roller 12 is 51 rpm.

[0068] The guide component is described in detail below:

[0069] Furthermore, such as Figure 3 As shown, the guide includes two guide sheet metal parts 5. The guide sheet metal parts 5 are located at the inlet of the frame 111 of the support frame 11. The guide sheet metal parts 5 are connected to the opposite sides of the inlet along the Y-axis, so that the guide sheet metal parts 5 on the opposite sides can provide guidance for the tobacco transfer box to enter the brush roller 12. Thus, the limiting and guiding effect of the guide sheet metal parts 5 can ensure that the entire tobacco transfer box is centered, that is, it can ensure that the tobacco transfer box is located in the middle of the brush rollers 12 on both sides. This ensures that the brushes on both sides can clean the tobacco transfer box evenly and stably, resulting in a better cleaning effect on the tobacco transfer box.

[0070] Specifically, such as Figure 3As shown, along the X-axis and in the conveying direction of the tobacco transfer box, the distance between the two guide sheet metal parts 5 gradually decreases. That is, the two guide sheet metal parts 5 are set with an flared structure to ensure that the guide sheet metal parts 5 have a better limiting and guiding effect on the tobacco transfer box, and to better ensure that the tobacco transfer box is placed in the middle of the brush rollers 12 on both sides.

[0071] The tobacco transfer box cleaning device in this embodiment, by setting up a first cleaning component 1, a second cleaning component 2, a conveying mechanism and a reversing mechanism that work together, can ensure the cleaning effect of the tobacco transfer box and the flexibility of the cleaning sequence.

[0072] The tobacco transfer box cleaning device in this embodiment, by setting up a dust collection hood 3, a negative pressure dust removal component and a receiving tray that work together, can achieve directional discharge and unified collection of tobacco, so as to avoid the problem of incomplete collection and waste of tobacco, thereby improving the utilization rate of tobacco.

[0073] The tobacco transfer box cleaning device in this embodiment, by setting up a photoelectric sensor and a drive unit 13 that work together, can realize the automatic identification function of the tobacco transfer box, thereby avoiding resource waste.

[0074] In this embodiment, the tobacco transfer box cleaning device guides the tobacco transfer box into the brush roller 12 through the guide sheet metal parts 5 on both sides, so as to ensure that the entire tobacco transfer box is centered, and thus ensure that the brushes on both sides can clean the tobacco transfer box evenly and stably.

[0075] In this embodiment, the tobacco transfer box cleaning device makes the filament bundle 122 of the brush roller 12 longer, so that the filament bundle 122 is closer to the tobacco transfer box. Even if the tobacco transfer box is slightly offset in the middle of the brush rollers 12 on both sides, it can still ensure that the filament bundle 122 of the longer brush roller 12 contacts the tobacco transfer box, thereby compensating for the problem of poor centering of the tobacco transfer box.

[0076] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
