Description

Technical Field

[0001] This application relates to the field of tobacco processing, and more specifically, to a cleaning device and conveying system. Background Technology

[0002] In the tobacco processing industry, belt conveyors are key equipment for material transport, widely used in the transfer of raw materials such as tobacco leaves and shredded tobacco. As an important component of the belt conveyor, the operating status of the belt rollers directly affects conveying efficiency and production safety.

[0003] In existing technologies, belt conveyor systems are typically equipped with cleaning devices to remove tobacco residue, dust, and other impurities adhering to the surface of the belt rollers. These cleaning devices are generally fixed in place or use simple mechanical linkages, employing brushes or scrapers to maintain contact with the belt roller surface and achieve continuous cleaning.

[0004] However, in actual operation, the belt rollers may shift position or have installation errors after long-term use. Combined with the dynamic deformation of the belt under load, this causes changes in the relative position between the cleaning device and the belt rollers, preventing the cleaning device from maintaining optimal contact with the belt rollers at all times. Under these conditions, tobacco leaves, dust, and debris can easily seep into the joint between the belt rollers and bearings, affecting not only the normal operation of the belt but also accelerating equipment wear and reducing its service life. Utility Model Content

[0008] In an optional embodiment, the cross-section of the opening is arranged in the shape of an arc, and the center of the arc is located on the same horizontal plane as the center of the belt roller.

[0009] In an optional embodiment, the scraper rotates relative to the body about a first axis, the axial direction of the first axis being parallel to the axial direction of the belt roller.

[0010] In an optional embodiment, the cleaning mechanism further includes a first driving member, which is mounted on the body and has its driving end fixedly connected to the scraper. The driving direction of the driving end is perpendicular to the axial direction of the first shaft.

[0011] In an optional embodiment, the cleaning mechanism further includes a second drive member, which is kinetically connected to the conveyor, which is configured as a spiral conveyor.

[0033] Example 1

[0034] Please see Figure 1 This embodiment applies to the cleaning belt roller 20. The belt roller 20 is cylindrical and rotates around its own axis, which is horizontal. A belt 30 is wound around the belt roller 20. The belt 30 is used to transport raw materials such as tobacco leaves and tobacco shreds.

[0035] This embodiment provides a cleaning device 10, which includes a frame 100 and a cleaning mechanism 200 and a locking mechanism 300 mounted on the frame 100.

[0036] The rack 100 serves as the mounting base element.

[0037] Please see Figures 1 to 3 The cleaning mechanism 200 includes a body 210, a scraper 220, a conveyor 230, and a collection tank 240.

[0038] The main body 210 is slidably mounted on the frame 100. When it slides into place, the main body 210 and the frame 100 are locked together by the locking mechanism 300.

[0039] Specifically, the main body 210 is provided with a receiving cavity 211, and the scraper 220 and the conveying component 230 are installed in the receiving cavity 211. The receiving cavity 211 is provided with an opening facing the belt roller 20, and the opening is adapted to the shape of the belt roller 20.

[0040] In some embodiments, the cross-section of the opening is circular, and the center of the arc is on the same horizontal plane as the center of the belt roller 20. In this embodiment, the opening direction can be set to be horizontal, and the outer contour of the receiving cavity 211 can be adapted to the belt roller 20.

[0041] The scraper 220 is mounted on the body 210 and is positioned toward the belt roller 20. It is understood that the scraper 220 is at least partially in contact with the belt roller 20. When the belt roller 20 is started to rotate, the scraper 220 remains stationary. Thus, the scraping motion of the scraper 220 on the belt roller 20 removes the impurities attached to the surface of the belt roller 20.

[0042] In some embodiments, the installation angle between the scraper 220 and the body 210 is not adjustable, that is, the scraper 220 is fixedly connected to the body 210, and the scraper 220 is always in contact with the belt roller 20 regardless of whether the belt roller 20 is in the running state or the stopped state.

[0043] In some other embodiments, please refer to Figure 1 , Figure 3 and Figure 4The installation angle between the scraper 220 and the body 210 is adjustable, which is achieved through the following design: the scraper 220 rotates relative to the body 210 around the first shaft 221, and the axial direction of the first shaft 221 is parallel to the axial direction of the belt roller 20. When the belt roller 20 is in operation, the scraper 220 contacts the belt roller 20 to perform cleaning work. When the belt roller 20 is in a stopped state, the scraper 220 is released from contact with the belt roller 20.

[0044] Specifically, the relative rotation between the scraper 220 and the body 210 is adjusted electrically. For example, the cleaning mechanism 200 also includes a first drive member 250, which is mounted on the body 210 and whose drive end is fixedly connected to the scraper 220. The drive direction of the drive end is perpendicular to the axial direction of the first shaft 221.

[0045] The first driving component 250 can be configured as a cylinder, hydraulic cylinder, or other component with telescopic function. The driving end of the first driving component 250 is set at an angle to the scraper 220, and this angle setting can be achieved by fixing it with a connector.

[0046] After the first driving member 250 extends, the scraper 220 rotates to abut against the belt roller 20. Conversely, after the first driving member 250 retracts, the scraper 220 rotates in the opposite direction to move away from the belt roller 20. In this embodiment, the extension and retraction frequency of the first driving member 250 can be set according to the penetration of impurities, thereby controlling the scraping frequency of the scraper 220 and reducing energy consumption while ensuring the cleanliness of the belt roller 20.

[0047] Please see Figure 2 , Figure 3 and Figure 5 The conveyor 230 is installed on the body 210 and located below the scraper 220. The conveyor 230 is used to convey the cleaning material, which is the impurities removed by the scraper 220, including but not limited to tobacco residue, tobacco dust and debris. After the scraper 220 removes the cleaning material, it falls onto the conveyor 230 under the action of gravity.

[0048] The cleaning mechanism 200 also includes a second drive member 260, which is connected to the conveyor member 230 in a transmission manner. When the conveyor member 230 is configured as a spiral conveyor, the second drive member 260 is configured as a motor. Of course, the conveyor member 230 can also be configured as a belt or other component with a conveying function. In this embodiment, the main body 210 also has a first mounting part 212, and the second drive member 260 is mounted on the first mounting part 212.

[0049] The frame 100 is provided with two oppositely arranged sliding grooves 110. The conveying component 230 passes through the sliding grooves 110, and both ends of the conveying component 230 are located in the two sliding grooves 110 respectively. The sliding direction of the conveying component 230 is consistent with the sliding direction of the body 210.

[0050] The collection tank 240 is located at the output end of the conveyor 230 and is used to collect the cleaned items from the conveyor 230, serving as a temporary storage location for the cleaned items. Specifically, the collection tank 240 and the conveyor 230 are connected by a flexible connection, which facilitates connection within a limited space.

[0051] Please see Figure 1 Each component of the cleaning mechanism 200 can slide relative to the frame 100 as a whole, thereby making the relative position between the cleaning mechanism 200 and the belt roller 20 adjustable, ensuring that the cleaning device 10 and the belt roller 20 maintain the best contact state.

[0052] Please see Figure 2 and Figure 6 The locking mechanism 300 includes an adjusting screw 310 and a nut 320. The adjusting screw 310 passes through the body 210 and is screwed to the frame 100. The number of nuts 320 is at least two. The two nuts 320 are screwed to the screw respectively, and the two nuts 320 are located on both sides of the body 210 respectively.

[0053] The main body 210 is also provided with a second mounting part 213, which is sleeved on the adjusting screw 310, and two nuts 320 are located on both sides of the second mounting part 213 respectively.

[0054] Please see Figure 3 and Figure 7 The cleaning mechanism 200 also includes a crusher 270, which is located at the output end of the collection tank 240.

[0055] In some embodiments, the shredder 270 is manually shredder.

[0056] In some other embodiments, the pulverizer 270 is an automatic pulverizer, and the cleaning mechanism 200 further includes a third drive member 280. The pulverizer 270 includes a housing 271, a moving member 272, and a fixed member 273. A plurality of fixed members 273 are spaced apart on the housing 271, and a plurality of moving members 272 are spaced apart on the housing 271. The drive end of the third drive member 280 is connected to the moving member 272 in a transmission manner, and the moving member 272 cooperates with the fixed member 273 to pulverize the cleaned material.

[0057] Specifically, the housing 271 includes a body portion 2711 and a cover portion 2712. The cover portion 2712 is hinged to the body portion 2711 and covers the body portion 2711. A fixed member 273 is disposed on the cover portion 2712, and a movable member 272 is disposed on the body portion 2711. When maintenance is required, the cover portion 2712 is opened, and after maintenance is completed, the cover portion 2712 is closed.

[0058] The crusher 270 also includes a feed pipe 274 and a discharge pipe 275. The cover part 2712 is connected to the collection tank 240 through the feed pipe 274, and the body part 2711 is connected to the discharge pipe 275. The cleaned material enters the housing 271 from the collection tank 240 through the feed pipe 274. Under the cooperation of the moving part 272 and the stationary part 273, it is broken down into small particles and then output from the discharge pipe 275.

[0059] To filter small particles, this embodiment may also include a filter section 2713 in the housing 271. The filter section 2713 is located at the connection between the discharge pipe 275 and the housing 271, thereby achieving the purpose of screening. Since the main body 2711 can be opened, it is convenient to perform periodic maintenance and cleaning of the filter section 2713, avoiding clogging.

[0060] In practical applications, the filter section 2713 is made of honeycomb-shaped filter sheets.

[0061] Please continue reading. Figure 1 , Figure 2 and Figure 6 If the belt 30 is stretched after normal use or the belt 30 or belt roller 20 is replaced and the belt 30 needs to be loosened, the belt roller 20 needs to be moved back and forth. At this time, the cleaning device 10 also needs to move accordingly with the belt roller 20 to ensure that the cleaning device 10 and the belt roller 20 are in the best contact state and improve the cleaning efficiency.

[0062] The steps for adjusting the sweeping device 10 are as follows: loosen the two nuts 320, push the sweeping device 10 back and forth until the distance between the opening and the belt roller 20 is appropriate, then tighten the two nuts 320 to fix the position of the sweeping device 10, and under the continuous operation of the belt roller 20, the scraper 220 performs a cleaning action on the belt roller 20.

[0063] During the process of pushing the cleaning device 10, the second mounting part 213 moves back and forth on the adjusting screw 310, and the conveying part 230 moves synchronously on the sliding groove 110.

[0064] Please see Figures 1 to 3 Based on the above, the operating principle of the cleaning device 10 will be further explained in this embodiment as follows:

[0065] S100. Loosen the locking mechanism 300, then push the cleaning device 10 to the appropriate position, and then lock the locking mechanism 300.

[0066] S200. Start belt roller 20.

[0067] S300. The first driving member 250 extends, the scraper 220 rotates to abut against the belt roller 20, and the impurities fall to the conveyor 230 under the action of the scraper 220, forming cleaned material.

[0068] S400. Start the second drive unit 260, and the conveyor 230 will operate to transport the swept material to the collection tank 240.

[0069] S500. Under the action of gravity, the swept material enters the crusher 270 and is crushed for subsequent recycling.

[0070] In this embodiment, the relative position between the cleaning mechanism 200 and the belt roller 20 is adjusted by sliding the body 210 onto the frame 100. Then, the locking mechanism 300 is used to lock the cleaning mechanism 200 and the frame 100, so that the scraper 220 and the belt roller 20 maintain the best contact state, thereby improving cleaning efficiency and reducing equipment wear.

[0073] The conveying device includes the belt roller 20 and belt 30 of Embodiment 1.

[0074] Specifically, the conveying system also includes a negative pressure device, which is connected to the discharge pipe 275, so that the discharge pipe 275, the feed pipe 274, the collection tank 240 and the conveying component 230 have a negative pressure effect, so that the cleaning material is transferred under the action of negative pressure in addition to gravity, thereby improving the transportation efficiency of the cleaning material.

[0075] To reduce manufacturing costs, this embodiment can be configured to have a negative pressure device connected to multiple discharge pipes 275.
