Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing vibrating screen equipment, specifically to a vibrating screen trough and a vibrating screen for recycling residual tobacco. Background Technology

[0002] Residual tobacco refers to the tobacco material obtained by processing defective cigarettes produced in the cigarette rolling and packaging process, separating non-tobacco components such as cigarette paper and filter tip.

[0003] Prior to this, the applicant disclosed a device and method for processing recycled tobacco (published in Chinese patent application CN107999512A). This device and method disclosed a processing flow for residual tobacco: pretreatment of damaged cigarettes → heating and humidifying cigarettes → primary separation – separation of light and heavy materials → secondary separation → separation of tobacco debris → photoelectric impurity removal → packing of tobacco into boxes → weighing of tobacco boxes and writing RFID information → warehousing of tobacco boxes. In the primary separation, secondary separation, and tobacco debris separation processes, a two-layer vibrating screen is used. The main function of the two-layer vibrating screen is to separate tobacco from cigarette paper. Its working principle is to use vibration to cause the tobacco to fall from the screen mesh into the lower layer. After subsequent impurity removal treatment, the tobacco meets the required blending standards.

[0004] However, in actual production, it was found that because the tobacco shreds were continuously transported forward through the bottom channel of the vibrating screen, long-term operation led to severe accumulation of tobacco oil and grime at the bottom of the screen. Since the upper screen plate was fixed to the side plates of the vibrating screen, cleaning and maintenance of the bottom of the screen became extremely cumbersome. Utility Model Content

[0041] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0042] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] The first aspect of this utility model provides a vibrating screen groove, such as Figures 1-3 As shown, the vibrating screen trough includes a vibrating screen trough body 3, a partition plate, a limiting block, a screen plate 10, and a drive assembly.

[0045] The vibrating screen trough 3 is defined by a vibrating screen trough bottom 7 and a first and a second vibrating screen side plate disposed opposite to each other on the vibrating screen trough bottom 7. The vibrating screen trough 3 has a feed inlet and a discharge outlet. A partition is disposed within the vibrating screen trough 3, dividing the vibrating screen trough 3 into an upper space and a lower space. The partition is provided with a screen plate mounting port communicating between the upper space and the lower space. The screen plate 10 is installed at the screen plate mounting port.

[0046] The vibrating screen trough 3 has two layers: the upper layer is above the partition plate, and the lower layer is below the partition plate and above the bottom 7 of the vibrating screen trough. It should be noted that both the upper and lower spaces have inlets and outlets. The inlet of the upper space is located above the screen plate 10, and the outlet is located at the end of the vibrating screen trough 3. The inlet of the lower space is the screen plate mounting port, and the outlet can be located at the end of the vibrating screen trough 3, depending on the situation. It is important to note that if the outlet of the upper space is also located at the end of the vibrating screen trough 3, the outlets of the upper and lower spaces must face different directions to prevent the separated materials from remixing.

[0047] After the mixed materials are screened by the screen plate 10, the materials with a diameter smaller than the mesh size of the screen plate 10 enter the lower space and are discharged through the outlet of the lower space, while the materials with a diameter larger than the mesh size of the screen plate 10 are discharged through the outlet of the upper space.

[0048] The limiting blocks are disposed opposite to each other on the inner sides of the first vibrating trough side plate and the second vibrating trough side plate. The driving assembly drives the limiting blocks on at least one side of the vibrating screen side plate to move toward or away from the other side of the vibrating screen side plate, so as to prevent or allow the screen plate 10 from disengaging from the screen plate mounting port, thereby realizing the detachable connection of the screen plate 10.

[0049] Furthermore, a screen plate support frame 8 is provided at the screen plate mounting opening, which supports the screen plate 10. Specifically, the screen plate support frame 8 supports the bottom of the screen plate 10. A receiving space for accommodating the screen plate 10 is formed between the screen plate support frame 8 and the limiting block. The driving assembly can drive the limiting block to shrink or expand the receiving space to prevent or allow the screen plate 10 from leaving the receiving space.

[0050] In practice, the limiting blocks on both sides of the vibrating trough side plate can be set as movable limiting blocks. By equipping corresponding driving components on both sides, the movable limiting blocks can be driven to move closer or further apart. This can prevent or allow the screen plate 10 from detaching from the screen plate mounting port, achieving detachable installation of the screen plate 10. However, this arrangement increases the number of driving components, increasing both the complexity of the equipment structure and its cost. Therefore, in a preferred embodiment of this utility model, a driving component is provided only on one side of the vibrating trough side plate, as detailed below:

[0051] The limiting block includes a fixed limiting block 4 and a movable limiting block 9. The fixed limiting block 4 is fixedly disposed on the inner side of the second vibrating groove side plate. The movable limiting block 9 is disposed on the inner side of the first vibrating groove side plate. The driving assembly 5 drives the movable limiting block 9 to move toward or away from the fixed limiting block 4 to prevent or allow the screen plate 10 from disengaging from the screen plate mounting port.

[0052] In one optional embodiment, the drive assembly 5 includes a threaded plate 5c, a screw 5b, and a handwheel 5a. The threaded plate 5c is disposed on the outer end face of the first vibrating groove side plate. The threaded plate 5c has a threaded hole. The screw 5b engages with the threaded hole and passes through the first vibrating groove side plate, where it is fixedly connected to the movable limiting block 9. In this embodiment, the first vibrating groove side plate necessarily has a hole through which the screw 5b passes. This hole can be a threaded hole adapted to the screw 5b with the same thread direction as the threaded hole on the threaded plate 5c, or it can be a through hole.

[0053] In another optional embodiment, the drive assembly 5 includes a screw 5b and a handwheel 5a. The screw 5b engages with a threaded hole on the side plate of the first vibrating groove, and passes through the threaded hole to be fixedly connected to the movable limiting block 9. The handwheel 5a is located at the other end of the screw 5b connected to the movable limiting block 9, and is used to drive the screw 5b to rotate.

[0054] The difference between the two implementations of the drive component 5 mentioned above is that the second implementation of the drive component 5 omits the threaded plate 5c and directly opens a threaded hole on the side plate of the first vibration groove. The screw 5b cooperates with the threaded hole, which can also realize the movement of the drive movable limit block.

[0055] Furthermore, the edge of the screen plate 10 is provided with reinforcing ribs 6 extending along the length direction of the screen plate 10. The upper end face of the reinforcing rib 6 is formed as an inclined structure A. The lower end faces of the fixed limiting block 4 and the movable limiting block 9 are formed as inclined structures B that match the inclined structure A.

[0056] When the handwheel 5a is rotated, the screw 5b pushes the movable limiting block 9 inward until the inclined structure B of the movable limiting block 9 is in contact with the inclined structure A on the reinforcing rib 6. With the pushing force, the inclined structure B of the fixed limiting block 4 on the other side is in contact with the inclined structure A of the reinforcing rib 6 on the other side of the screen plate 10. Under the action of the pushing force, the reinforcing ribs 6 on both sides of the screen plate 10 are pressed against the movable limiting block 9 and the fixed limiting block 4, thereby fixing the screen plate 10 and preventing the screen plate 10 from loosening under vibration.

[0057] When disassembling the screen plate 10, rotate the handwheel 5a in the opposite direction, and the movable limit block 9 will disengage from the reinforcing rib 6. Then, remove the screen plate 10 and clean the bottom trough of the vibrating screen.

[0058] The inclined structure increases the contact area between the movable limiting block 9 and the fixed limiting block 4. Furthermore, the movable limiting block 9 and the fixed limiting block 4 extend along the length of the first and second vibrating groove side plates, respectively. That is, both the movable limiting block 9 and the fixed limiting block 4 have a certain length to increase the contact area between them and improve the stability of the screen plate 10 installation.

[0059] In one optional embodiment, if both the movable limiting block 9 and the fixed limiting block 4 have a certain length, a driving component is provided at each end of the movable limiting block 9.

[0060] The second aspect of this utility model provides a vibrating screen for recycling residual tobacco shreds, such as... Figure 1As shown, the vibrating screen for recycling residual tobacco includes a screen trough, a screen support 1, and a vibrating motor 3. The screen support 1 supports the screen trough. The vibrating motor 3 is located at the bottom of the screen trough.

[0061] Of course, the recyclable tobacco shreds vibrating screen also includes a damping spring group (or a vibration isolation spring system), which serves to provide structural support and buffering, connect the vibrating trough body and the vibrating screen support 1, bear alternating loads, and reduce the transmission of impact.

[0062] Based on the design of the vibrating screen trough, the vibrating screen for recycling residual tobacco of this invention can achieve detachable connection of the screen plate 10, enabling equipment maintenance personnel to efficiently complete the disassembly and assembly of the screen plate, thereby facilitating the cleaning of the bottom of the vibrating trough.

[0063] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0064] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0065] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
