Description

Technical Field

[0001] This invention belongs to the technical field of dust removal equipment for cigarette factories, specifically relating to a dust removal device for a cigarette manufacturing workshop. Background Technology

[0002] The function of environmental dust removal devices is to absorb the dust generated during the production process, filter the air containing dust, and discharge it as clean air. At the same time, the filtered dust is collected and treated to ensure the cleanliness of the workshop environment. The function of centralized process dust removal systems is generally to provide the necessary process airflow for labeling machines and filling machines to meet the negative pressure required for production.

[0003] Currently, the main function of the tobacco storage room in the cigarette processing workshop is to store finished tobacco shreds and transport them to the cigarette rolling machines in the packaging workshop. During the process of transporting the tobacco shreds via belt conveyors, dust will be generated, especially at the material discharge end of the belt conveyor. Therefore, dust removal treatment is required in the tobacco storage room. However, the existing dust removal methods in the tobacco storage room generally use separate negative pressure equipment and dust removal equipment to form a dust removal device for suction and dust removal, resulting in a non-compact structure of the dust removal device and a large space occupation. In addition, both the negative pressure equipment and the dust removal equipment require drive mechanisms, resulting in a large number of drive mechanisms.

[0004] Therefore, how to design a dust removal device for cigarette manufacturing workshops in a way that makes the device more compact and reduces the number of drive mechanisms has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0039] like Figures 1 to 4As shown, this embodiment of the invention provides a dust removal device for a cigarette manufacturing workshop, comprising a base plate 6, a dust collection cylinder, a dust removal mechanism, and a fan. Two first support plates 2 are arranged opposite each other on the left side of the top surface of the base plate 6, and two second support plates 7 are arranged opposite each other on the right side of the top surface of the base plate. A first roller shaft 1 is rotatably connected between the two first support plates 2, and a second roller shaft 10 is rotatably connected between the two second support plates 7. The second roller shafts are parallel to the first roller shafts, and a transmission belt 11 is drivingly connected between the first roller shaft 1 and the second roller shaft 10. A driving mechanism for driving the second roller shaft 10 to rotate is provided on the second support plate. The dust collection cylinder 15 is fixedly connected between the two first support plates 2, and the dust collection cylinder 15 is located above the first roller shaft. Both the upper and lower ends of the dust collection cylinder 15 are open. The fan is located in the lower opening of the dust collection cylinder. The front end of the first roller shaft 1 is connected to the fan through a transmission mechanism to drive the fan to rotate for dust collection. A dust removal mechanism is provided in the upper opening of the dust collection cylinder.

[0040] The dust removal device for cigarette manufacturing workshops provided in this embodiment of the invention integrates both the dust extraction fan and the dust removal mechanism within the dust extraction cylinder 15. Compared to the prior art which uses separate negative pressure equipment and dust removal equipment, this makes the overall structure of the dust removal device more compact and effectively reduces the space it occupies. Furthermore, the drive mechanism can not only drive the conveyor belt but also rotate the fan for dust extraction, eliminating the need for a separate drive mechanism for the fan and thus effectively reducing the number of drive mechanisms required.

[0041] Further, the transmission mechanism includes a first helical gear 3, a second helical gear, a third helical gear, a fourth helical gear, a fifth helical gear, and a sixth helical gear. The front end of the first roller shaft has an extension section that extends through the first support plate. The first helical gear 3 is coaxially connected to the extension section, and the extension section is coaxial with the first roller shaft. A fixing plate 26 is horizontally arranged on the front side wall of the first support plate 2 located in front. A first rotating shaft 5 is rotatably connected to the fixing plate. The first rotating shaft is vertically arranged, and a second helical gear 4 for meshing with the first helical gear 3 is arranged at the lower end of the first rotating shaft 5. The third helical gear 12 is fixedly connected to the upper end of the first rotating shaft 5, and the fourth helical gear 13 is meshed on the third helical gear 12. A second rotating shaft 14, coaxial with the fourth helical gear 13, is disposed at the middle of the fourth helical gear 13. The second rotating shaft 14 passes through a first through hole on the first support plate and a second through hole on the front side plate of the dust collection cylinder and extends into the lower port of the dust collection cylinder. The second rotating shaft is rotatably disposed in the first and second through holes. The rear end of the second rotating shaft 14 is fixedly connected to the fifth helical gear 21. A horizontal plate is disposed in the lower port of the dust collection cylinder, and the horizontal plate is located below the second rotating shaft. Both the horizontal plate and the second rotating shaft are parallel to the first roller shaft. The rotating rod 25 of the fan is rotatably connected to the horizontal plate. The rotating rod is vertically disposed, and a sixth helical gear 22 for meshing with the fifth helical gear 21 is disposed at the upper end of the rotating rod. With this scheme, the drive mechanism drives the second roller shaft to rotate, and then drives the first roller shaft to rotate through the conveyor belt. The first roller shaft then drives the fan to rotate through the transmission mechanism to perform dust collection.

[0042] Specifically, the first helical gear 3, the second helical gear 4, the third helical gear 12, the fourth helical gear 13, the fifth helical gear 21, and the sixth helical gear 22 are all made of high wear-resistant titanium alloy, i.e., titanium alloy with good wear resistance, so that each helical gear has a long service life.

[0043] Furthermore, the dust removal mechanism is an electrostatic dust removal mechanism, which includes a positive electrode plate 16 and a negative electrode plate 17. The positive electrode plate 16 and the negative electrode plate 17 are respectively fixedly connected to the left inner wall and the right inner wall of the upper opening of the dust collection cylinder 15. A power supply device is provided between the positive electrode plate 16 and the negative electrode plate 17, so that dust removal can be achieved by electrostatic dust removal.

[0044] Specifically, the power supply device includes a second magnetic block 19 and a plurality of first magnetic blocks 18. The plurality of first magnetic blocks 18 are fixedly connected in a ring array to the outer circumferential surface of the rear end of the second rotating shaft 14. The second magnetic block 19 is fixedly connected to the front side of the top surface of the horizontal plate 23. The second magnetic block 19 is positioned close to the first magnetic blocks 18. An induction wire 20 is wound around the second magnetic block 19. The positive and negative terminals of the induction wire 20 are electrically connected to the positive plate 16 and the negative plate 17, respectively. With this scheme, when the second rotating shaft 14 rotates, it drives the plurality of first magnetic blocks 18 to rotate. The plurality of first magnetic blocks 18 continuously cut the magnetic field lines of the second magnetic block 19, causing the induction wire 20 on the second magnetic block 19 to generate an induced current. The positive and negative terminals of the induction wire 20 are electrically connected to the positive plate 16 and the negative plate 17, respectively, so that the positive plate 16 and the negative plate 17 are positively charged and negatively charged, respectively, thereby realizing electrostatic dust removal.

[0045] Preferably, a plurality of spikes 28 are fixedly connected to the inner wall of the negative electrode plate 17, so as to facilitate electrostatic dust removal by discharging using the spikes.

[0046] Specifically, the positive electrode plate 16, the negative electrode plate 17, and the spikes are all made of copper with good conductivity, and the dust collection cylinder 15 is made of insulating material.

[0047] Preferably, a collection box 27 is provided on the lower inner wall of the positive electrode plate 16, and the upper end of the collection box is open, so that the dust on the positive electrode plate can fall into the collection box and be collected for centralized treatment.

[0048] Furthermore, the driving mechanism is a motor 9. A mounting plate 8 is horizontally arranged on the front side wall of the second support plate 7 located at the front. The motor is mounted on the top surface of the mounting plate 8, and the output shaft of the motor 9 is coaxially connected to the front end of the second roller 10. It can be understood that the second support plate is provided with a through hole through which the output shaft of the motor passes, and the output shaft of the motor rotates in conjunction with the through hole. The dust collection cylinder 15 is located above the first roller 11, that is, the dust collection cylinder is located above the left end of the conveyor belt 11, and the left end of the conveyor belt is the material drop end.

[0049] Specifically, the dust collection cylinder 15 has a cylinder structure that is narrow at the top and wide at the bottom, so that it can easily collect dust by using its wider lower opening and facilitate dust removal by using its narrower upper opening.

[0050] The general working process of this invention is as follows: In use, the motor 9 is first started, driving the second roller 10 to rotate. The second roller 10 drives the first roller 1 to rotate via the conveyor belt 11. Then, the tobacco is conveyed on the conveyor belt 11 and falls off at the end of the conveyor belt 11 near the dust collection cylinder 15. The rotation of the first roller 1 drives the first rotating shaft 5 to rotate via the first helical gear 3 and the second helical gear 4. The rotation of the first rotating shaft 5 drives the second rotating shaft 14 to rotate via the third helical gear 12 and the fourth helical gear 13. The second rotating shaft 14 drives the rotating rod 25 to rotate via the fifth helical gear 21 and the sixth helical gear 22. The rotation of the rotating rod 25 drives the fan blades 24 to rotate. The rotation of the fan blades 24 sucks the dust generated when the tobacco falls off the conveyor belt into the dust collection cylinder 15 and flows into the upper opening of the dust collection cylinder 15. While rotating, the motor 14 drives multiple first magnetic blocks 18 to rotate. The multiple first magnetic blocks 18 continuously cut the magnetic field lines of the second magnetic block 19, causing the induction wires 20 on the second magnetic block 19 to generate an induced current. The positive and negative ends of the induction wires 20 are electrically connected to the positive plate 16 and the negative plate 17 respectively, so that the positive plate 16 and the negative plate 17 are positively charged and negatively charged respectively. A large number of negative charges on the negative plate 17 will focus on the spikes, causing a tip discharge. When the large number of electrons released move towards the positive plate 16, they can carry and adsorb the dust passing between the positive plate 16 and the negative plate 17 onto the inner wall of the positive plate 16, forming an electrostatic dust removal effect. When the motor 9 is turned off, the positive plate 16 and the negative plate 17 no longer carry positive and negative charges, and the dust on the positive plate 16 will fall into the collection box 27 and be collected.

[0051] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
