Description

Technical Field

[0001] The present invention relates to a dredging tool, in particular to a rapid dredging tool set for the blockage of the sieve mesh in the tobacco production line. Background Art

[0002] In the tobacco manufacturing industry, the tobacco production line is a crucial production link, and its efficiency and product quality directly affect the economic benefits of the entire production process. As a key device in the tobacco production line, the sieve mesh undertakes the important task of separating and screening tobacco particles of different sizes. However, with the extension of production time, the sieve mesh often suffers from problems such as the accumulation and adhesion of tobacco particles and blockage by impurities, resulting in a significant decline in the screening efficiency, and further affecting the uniformity and quality stability of tobacco products.

[0003] To solve the problem of sieve mesh blockage, traditional methods mainly rely on manual dredging. This method is not only inefficient but also easily causes physical damage to the sieve mesh, shortening its service life. In addition, manual dredging is difficult to ensure the uniformity and consistency of the dredging effect, further affecting production efficiency and product quality. In recent years, with the development of automation technology, some semi-automatic or fully automatic sieve mesh dredging devices have gradually emerged. However, these devices often have complex structures, cumbersome operations, and lack sufficient adaptability and flexibility for specific sieve mesh types and blockage degrees. Especially when the sieve mesh is severely blocked, these devices are often difficult to dredge quickly and effectively, resulting in production interruption and increasing the operating costs of enterprises. Therefore, it is necessary for staff to improve them. Summary of the Invention

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0026] Embodiment 1 of the present invention: Figures 1 - 10 As shown, a tool set for quickly clearing blockage in a silk wire screen comprises a mounting sleeve 1, the top of which is connected to a handle, a first electric telescopic rod 2 is fixedly provided on the top of the mounting sleeve 1, a clearing column 3 is slidably installed in the mounting sleeve 1, a step hole is provided at the center of the clearing column 3, an output shaft 30 of the first electric telescopic rod 2 is plug-connected with the step hole, and a limiting nut 31 is installed at the end of the output shaft 30.

[0027] The stepped hole at the center of the dredging column 3 is a structure that is small at the top and large at the bottom. The diameter of the upper part of the stepped hole is slightly larger than the diameter of the output shaft 30, and the diameter of the lower part of the stepped hole is slightly larger than the diameter of the limit nut 31, ensuring that the output shaft 30 can move smoothly in the stepped hole.

[0028] Further, an installation disk 4 is fixedly provided on the inner wall of the installation sleeve 1. An electric telescopic rod avoidance hole 32 is formed in the installation disk 4. A plurality of first tension springs 5 are fixedly connected to the bottom of the installation disk 4. First installation grooves 33 corresponding to the first tension springs 5 one by one are formed in the dredging column 3. The first tension springs 5 are inserted into the first installation grooves 33 one by one. A second electric telescopic rod 6 is inserted into each first tension spring 5. The top end of the second electric telescopic rod 6 is fixedly connected to the bottom of the installation disk 4. The output end of the second electric telescopic rod 6 is fixedly connected with a sleeve 7. A distributor 8 is fixedly connected to the inner wall of the sleeve 7. The bottom end of the distributor 8 is electrically connected to an iron core 9. A negative magnetic attraction block 10 is fixedly provided at the bottom of each first installation groove 33. The top of the negative magnetic attraction block 10 abuts against the bottom of the iron core 9.

[0029] The installation disk 4 is mainly used for installing the first tension springs 5 and the second electric telescopic rods 6. In this embodiment, the installation disk 4 is fixedly provided at a position slightly above the middle inside the installation sleeve 1. In order to ensure the installation stability of the first electric telescopic rod 2, a cross-shaped support rod 35 is further provided inside the installation sleeve 1. A through hole is formed in the center of the cross-shaped support rod 35. The first electric telescopic rod 2 is in interference fit with the through hole in the cross-shaped support rod 35. The end of the cross-shaped support rod 35 is fixedly connected to the inner wall of the installation sleeve 1. The cross-shaped support rod 35 can effectively ensure that the first electric telescopic rod 2 is coaxial with the installation sleeve 1.

[0030] During use, the first electric telescopic rod 2 is powered on. Through the telescopic movement of the first electric telescopic rod 2, the dredging column 3 is driven to move up and down, and then the screen is impacted and dredged. The installation disk 4 is fixed on the inner wall of the installation sleeve 1. The first electric telescopic rod 2 penetrates through the installation disk 4. A plurality of groups of first tension springs 5 are connected to the bottom of the installation disk 4. The bottom end of the first tension spring 5 is fixed to the inner wall of the first installation groove 33, which can provide elastic support when the dredging column 3 moves and ensure the smoothness of the dredging action. The top end of the second electric telescopic rod 6 is fixed to the top of the installation disk 4, and the output end is connected with a sleeve 7. A distributor 8 is arranged inside the sleeve 7. The bottom end of the distributor 8 is electrically connected to an iron core 9. After the iron core 9 is electrified, it forms a positive magnetic attraction block. The iron core 9 and the negative magnetic attraction block 10 are connected by magnetic attraction to ensure that the dredging column 3 remains stable when not in use. When the dredging column 3 needs to move, the iron core 9 is powered off, so that the output end of the second electric telescopic rod 6 can be easily retracted. Then when the first electric telescopic rod 2 impacts the dredging column 3, the first tension spring 5 can easily reset the dredging column 3 in time, and thus the dredging column 3 can quickly impact the screen.

[0031] Embodiment 2 of the present invention: On the basis of Embodiment 1, as Figures 1 - 10As shown in the figure, a receiving cavity is formed in the dredging column 3. A plurality of connecting holes 11 are formed in the bottom plate of the dredging column 3. The bottom plate of the dredging column 3 is a detachable structure. A disc 12 is installed in the receiving cavity. A plurality of cleaning hairs 13 are fixedly connected to the bottom of the disc 12. The cleaning hairs 13 are inserted and matched with the connecting holes 11. A plurality of second tension springs 14 are fixedly connected to the top of the disc 12. A plurality of second installation grooves 34 are formed at the top of the receiving cavity. The second tension springs 14 are inserted and connected to the second installation grooves 34 one by one.

[0032] During use, the disc 12 can move up and down in the receiving cavity. The cleaning hairs 13 at the bottom of the disc 12 extend out of the bottom plate of the dredging column 3 through the connecting holes 11, and can brush the screen during the dredging process to remove blockages. A plurality of second tension springs 14 are fixedly connected to the top of the disc 12. The top ends of the second tension springs 14 are fixed to the top inside the second installation grooves 34. The second tension springs 14 can provide elastic support for the disc 12 when the dredging column 3 moves up and down, ensuring that the cleaning hairs 13 can flexibly expand and contract when contacting the screen to avoid damaging the screen. When the dredging column 3 moves downward, the cleaning hairs 13 extend out through the connecting holes 11 to brush the screen and remove blockages; when the dredging column 3 moves upward, the second tension springs 14 pull the fixed disc 12 and the cleaning hairs 13 back into the receiving cavity to avoid unnecessary friction of the cleaning hairs 13 on the screen in the non-working state. The dredging column 3 can not only dredge the screen by moving up and down to impact the screen, but also further remove the blockages on the screen through the brushing action of the cleaning hairs 13 to ensure the smoothness of the screen.

[0033] Embodiment 3 of the present invention: On the basis of Embodiment 1 or Embodiment 2, as Figures 1 - 10 shown, an assembly block 15 is fixedly provided on the outer wall of the lower end of the installation sleeve 1. A clamping block 16 is installed on the assembly block 15. A connecting box 17 is fixedly connected to the clamping block 16. A plurality of conical nozzles 18 are provided at the bottom of the connecting box 17.

[0034] A mounting head 19 is fixedly connected to the top of the connecting box 17. The surface of the mounting head 19 has threads. An assembly pipe 20 is threadedly connected to the mounting head 19. The top end of the assembly pipe 20 is fixedly connected to a connecting hose 21.

[0035] During use, the clamping block 16 is installed on the assembly block 15, enabling the connection box 17 to be stably and flexibly installed at the required position, while facilitating disassembly and maintenance. A number of conical nozzles 18 are fixedly connected to the bottom of the connection box 17. The conical design can ensure that the cleaning fluid (including cleaning gas or cleaning liquid) forms a pressurized spray when ejected, thereby covering a wider screen area and improving the cleaning efficiency. The mounting head 19 is tightly connected to the top of the connection box 17 and is tightly combined with the assembly pipe 20 by means of threaded connection. The top end of the assembly pipe 20 is connected to the connection hose 21. The connection hose 21, as a transmission channel for the cleaning fluid, has high flexibility and durability. It can not only convey high-pressure cleaning gas into the connection box 17 to blow out the fine blockages on the screen, but also convey cleaning liquid, which can penetrate deeply and dissolve the stubborn stains on the screen through the uniform spraying of the conical nozzles 18.

[0036] Embodiment 3 of the present invention: On the basis of Embodiment 1 or Embodiment 2 or Embodiment 3, as Figures 1 - 10 shown, the handle includes a threaded sleeve rod 22, a connection slider 23 and a protective rod 24. The lower end of the threaded sleeve rod 22 is fixedly connected to the top end of the mounting sleeve 1. A connection slider 23 is fixedly connected to the outer wall of the threaded sleeve rod 22. The threaded sleeve rod 22 is inserted and connected with the protective rod 24. A guide groove is provided on the inner wall of the protective rod 24. The connection slider 23 is located in the guide groove, and the connection slider 23 is slidably matched with the guide groove; a grip 25 is fixedly connected to the top end of the protective rod 24, and a control switch 26 is provided at the top end of the grip 25.

[0037] A servo motor 27 is fixedly provided in the grip 25. A drive rod 28 is installed at the output end of the servo motor 27. A threaded rod 29 is fixedly connected to the bottom end of the drive rod 28. The threaded rod 29 is threadedly connected to the inner wall of the threaded sleeve rod 22.

[0038] During use, the threaded sleeve rod 22 and the threaded rod 29 are in threaded cooperation, enabling the height of the entire tool set to be flexibly adjusted according to actual needs. The connection slider 23 is fixed to the top end of the threaded sleeve rod 22 and slides on the inner wall of the protective rod 24 to ensure the smoothness of the adjustment process. The protective rod 24 provides additional protection for the entire tool set. The grip 25 is located at the top end of the protective rod 24. The control switch 26 enables the user to conveniently control the start and stop of the entire tool set through it, as well as adjust the rotation speed of the servo motor 27, thereby achieving precise control of the dredging force. The drive rod 28 transmits the power of the servo motor 27 to the threaded rod 29, and through the rotation of the threaded rod 29 in the threaded sleeve rod 22, the precise adjustment of the height of the entire tool set is achieved.

[0039] Working principle: When the first electric telescopic rod 2 works, it will push or pull the dredging column 3 to move up and down. When the second electric telescopic rod 6 works, it can control the movement of the sleeve pipe 7, and further control the relative position relationship between the distributor 8 and the iron core 9 at its lower end and the negative magnetic attraction block 10, generating a magnetic attraction or release action.

[0040] The first tension spring 5 is connected between the mounting plate 4 and the dredging column 3, providing elastic support for the dredging column 3. When the dredging column 3 is impacted or pressured, the first tension spring 5 can buffer these forces, protecting the dredging column 3 and the screen from damage. The second tension spring 14 connected to the top of the disc 12 also plays an elastic support role, enabling the cleaning brush 13 to flexibly expand and contract when contacting the screen, adapting to different blockage situations and avoiding unnecessary friction on the screen.

[0041] When the second electric telescopic rod 6 pushes the sleeve pipe 7 and the distributor 8 inside it to move downward, the iron core at the bottom of the distributor approaches the negative magnetic attraction block 10, generating a magnetic attraction between them. This magnetic attraction can further strengthen the stability of the dredging column 3 during operation. When it is necessary to release the dredging column 3, the second electric telescopic rod 6 pulls the sleeve pipe 7 upward, the iron core 9 separates from the negative magnetic attraction block 10, and the dredging column 3 returns to its original position under the action of the first tension spring 5.

[0042] When the dredging column 3 moves downward, the cleaning brush 13 contacts the screen and brushes it to remove blockages. When the dredging column 3 moves upward, the second tension spring 14 pulls the disc 12 and the cleaning brush 13 back into the accommodation cavity, avoiding friction on the screen in the non-working state.

[0043] The conical nozzle 18 at the bottom of the connection box 17 accesses the cleaning liquid through the connection hose 21. When spray cleaning is required, the cleaning liquid is sprayed out through the conical nozzle 18 to spray clean the screen. The combination of spraying and dredging can further improve the dredging efficiency and effect, ensuring the smoothness of the screen.

[0044] The servo motor 27 in the grip 25 is connected to the threaded rod 29 through the drive rod 28, and the threaded rod 29 is threadedly connected to the inner wall of the threaded sleeve rod 22. When the servo motor 27 works, it can drive the entire tool set to adjust the height. The operator can conveniently control the rotation speed of the servo motor 27 and the impact force of the first electric telescopic rod 2 through the control switch 26, thereby achieving precise control of the dredging force.

[0045] The above has detailed the structure, characteristics and function effects of the present invention according to the illustrated embodiments. The above is only the preferred embodiment of the present invention, but the present invention is not limited to the scope shown in the drawings. Any changes made according to the concept of the present invention, or modified into equivalent embodiments of equivalent changes, still within the spirit covered by the description and the drawings, shall be within the protection scope of the present invention.
