Description

Technical Field

[0001] This utility model relates to the field of cigarette filter rod technology, and in particular to a dustproof device. Background Technology

[0002] Filter rods have become one of the most important cigarette materials in the cigarette industry, playing a crucial role in the technological development of reducing tar and harm in cigarettes. Currently, the main component of cigarette filter rods is cellulose acetate tow. Cellulose acetate tow is made from natural fibers (wood or cotton fibers) and acetic anhydride as the main raw materials. Through artificial synthesis of cellulose acetate, hydrolysis, filtration, and degassing, it is formed into filaments under high pressure through a spinneret. The filaments then pass downwards through a drying chamber, where hot air evaporates acetone and solidifies the filaments. After being gathered, curled, dried, spun, packaged, and shipped, the process is crucial. During the tow manufacturing process, some broken filaments and fly ash are generated and adhere to the tow. During filter rod production, these broken filaments float around as the tow is used, and long-term inhalation can cause serious health hazards.

[0003] To address this issue, most existing dustproof devices used for filter rod forming are dust covers, while some combine dust covers and dust curtains. However, when changing the fiber bundle, the dust cover or dust curtain must be opened manually, which is not only time-consuming and labor-intensive, affecting work efficiency, but also poses certain safety hazards.

[0004] Therefore, a dustproof device is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof device that is not only simple in structure, but also capable of automatically folding or opening the dustproof curtain, thus ensuring the dustproof effect while fully freeing up manpower, improving work efficiency, and reducing safety hazards.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0010] The conveying mechanism is capable of conveying workpieces horizontally.

[0011] A lifting mechanism, located below the dustproof curtain, is capable of receiving the conveyed workpiece and driving the workpiece vertically to allow it to enter the dustproof space for operation or to move out from the bottom of the dustproof space.

[0012] Preferably, the conveying mechanism includes an input platform and an output platform, and the lifting mechanism is disposed between the input platform and the output platform. The input platform can convey the workpiece to the lifting mechanism, and the output platform can convey the tray at the bottom of the workpiece after the operation is completed.

[0013] Preferably, the workpiece further includes a wire bundle, which is located on the tray. The bottom end of the dust curtain is higher than the conveying mechanism, and after the lifting mechanism receives the workpiece, the top end of the wire bundle is higher than the bottom end of the dust curtain.

[0014] Preferably, the lifting mechanism includes a balance platform and a lifting component. The balance platform is disposed on the lifting component. When the weight of the workpiece on the balance platform decreases, the lifting component can drive the balance platform to rise.

[0015] Preferably, the balancing platform is provided with a conveying surface, which can receive the workpiece and convey the tray to the output platform.

[0016] Preferably, the dustproof component further includes a dust cover, which is disposed at the top of the dustproof curtain, and the dust cover can form the dustproof space together with the dustproof curtain.

[0017] Preferably, the driving mechanism includes a driving component and a sliding component, both of which are disposed on the dust cover. The sliding component is connected to the dust curtain, and the driving component can drive the sliding component to move the dust curtain to open and close the dustproof space.

The dust cover is connected to the bottom end of the slider, and the slider is slidably connected to the slide rail.

[0019] Preferably, the dust curtain is made of a transparent flexible material and is detachably connected to the sliding assembly.

[0020] Preferably, the drive mechanism further includes a control component, which is disposed on one side of the transmission mechanism and is communicatively connected to the drive component.

[0021] The beneficial effects of this utility model are:

[0022] This utility model discloses a dustproof device. The dustproof device includes a dustproof component, a drive mechanism, a conveying mechanism, and a lifting mechanism. The dustproof component includes a dustproof curtain that forms a dustproof space, within which an adsorption element is installed; the drive mechanism drives the dustproof curtain to move, opening and closing the dustproof space; the conveying mechanism conveys workpieces horizontally; the lifting mechanism is located below the dustproof curtain, receiving the conveyed workpieces, and also drives the workpieces vertically, allowing them to enter the dustproof space for operation or be moved out from the bottom of the dustproof space.

[0023] The conveying mechanism automatically transports workpieces, and the lifting mechanism automatically receives and elevates them into a dust-proof workspace. The dust-proof curtain effectively prevents dust accumulation, avoiding the contamination of the work environment by broken wires and flying debris. Simultaneously, the adsorption components promptly absorb impurities within the dust-proof space, preventing them from escaping from the bottom of the curtain. When workpiece replacement is needed, the drive mechanism automatically opens the dust-proof curtain, thus opening the dust-proof space and preventing interference between the workpiece and the curtain, ensuring high operational efficiency. This process guarantees excellent dust control, significantly reduces labor costs, increases automation, and minimizes safety hazards. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This embodiment provides a dustproof device, specifically as follows: Figure 1 As shown, the device includes a dustproof component 10, a drive mechanism 20, a conveying mechanism 30, and a lifting mechanism 40. The dustproof component 10 includes a dustproof curtain 11, which can form a dustproof space, and an adsorption element 13 is provided in the dustproof space. The drive mechanism 20 can drive the dustproof curtain 11 to move, so as to open and close the dustproof space. The conveying mechanism 30 can convey the workpiece 100 in the horizontal direction. The lifting mechanism 40 is located below the dustproof curtain 11, which can receive the conveyed workpiece 100, and the lifting mechanism 40 can drive the workpiece 100 in the vertical direction so that the workpiece 100 can enter the dustproof space for operation or move out from the bottom of the dustproof space.

[0036] In this device, the conveying mechanism 30 automatically conveys the workpiece 100, and the lifting mechanism 40 automatically receives the workpiece 100 and lifts it into the dustproof space for operation. The dustproof space enclosed by the dustproof curtain 11 provides sufficient dust protection, preventing broken wires and flying debris from contaminating the working environment. Simultaneously, the adsorption component 13 promptly adsorbs impurities within the dustproof space, preventing them from flying out from the bottom of the dustproof curtain 11. When it is necessary to change the workpiece 100, the drive mechanism 20 automatically opens the dustproof curtain 11, thereby opening the dustproof space and preventing interference between the workpiece 100 and the dustproof curtain 11, ensuring good operational efficiency. This process ensures excellent dust protection, significantly reduces labor costs, increases automation, and reduces safety hazards.

[0037] It should be noted that, in this embodiment, as Figure 1 As shown, workpiece 100 includes a pallet 110 and a wire bundle 120. The wire bundle 120 is located on the pallet 110, and the pallet 110 is transferred and enters the dustproof space together with the wire bundle 120. However, since only the wire bundle of the wire bundle 120 participates in the operation, the wire bundle will be left on the pallet 110 after it is completely used. If manual handling is used, it will affect subsequent operations and reduce work efficiency.

[0038] To solve this problem, such as Figure 1 As shown, the conveying mechanism 30 includes an input platform 31 and an output platform 32. A lifting mechanism 40 is disposed between the input platform 31 and the output platform 32. The input surface 311 of the input platform 31 can convey the workpiece 100 to the lifting mechanism 40, and the output surface 321 of the output platform 32 can convey the tray 110 at the bottom of the workpiece 100 after the operation is completed. In this structure, the input surface 311 can convey the workpiece 100 to the lifting mechanism 40, and after the operation is completed, only the tray 110 remains on the lifting mechanism 40. After the tray 110 is moved to the output surface 321, the output surface 321 can automatically output the tray 110, thereby ensuring the cleanliness of the plane of the conveying mechanism 30. At the same time, there is no need for manual removal of the tray 110 from the conveying mechanism 30, reducing labor costs.

[0039] It should be noted here that, as Figure 1As shown, the lifting mechanism 40 includes a balance platform 41 and a lifting component 42. The balance platform 41 is mounted on the lifting component 42 and has a conveying surface 411. When the conveying surface 411 is flush with the input surface 311, it can receive the workpiece 100 transferred from the input platform 31. When the conveying surface 411 is flush with the output surface 321, it can transfer the tray 110 to the output platform 32. This configuration allows the conveying surface 411 to automatically transport the workpiece 100 to the bottom of the dustproof space after it is transferred to the balance platform 41, facilitating subsequent operations. At the same time, the conveying surface 411 can also directly transfer the tray 110 to the output surface 321. Therefore, the process of the balance platform 41 receiving the workpiece 100 and adjusting it to the preset position, as well as transferring the tray 110 to the output surface 321, requires no manual operation, further improving the degree of automation and enhancing the safety and convenience of the operation.

[0040] In existing technologies, the bottom end of the dust curtain 11 usually rests on the balance table 41 after closing, which not only affects the aesthetics of the structure but also the conveying of the workpiece 100. To solve this problem, such as Figure 1 As shown, the bottom of the dust curtain 11 is higher than the conveying mechanism 30, and after the lifting mechanism 40 receives the workpiece 100, the top of the wire bundle 120 is higher than the bottom of the dust curtain 11, meaning the bottom of the dust curtain 11 is suspended. This arrangement prevents the dust curtain 11 from contacting the balance table 41, the input table 31, and the output table 32, ensuring the aesthetics of the structure. It also prevents interference with the dust curtain 11 when conveying the workpiece 100 or the tray 110, ensuring good conveying performance.

[0041] However, this structure presents a problem: as working time increases, the filaments in the filament bundle 120 are gradually used. When the height of the filament bundle 120 drops below the dust curtain 11, broken filaments and flyaways will fly out of the dust-proof space through the gap between the dust curtain 11 and the balance table 41, thus affecting the environment. To solve this problem, when the weight of the workpiece 100 on the balance table 41 decreases, the lifting component 42 can drive the balance table 41 to rise, and can always keep the working height of the filament bundle 120 above the bottom of the dust curtain 11. In this structure, regardless of the size of the filament bundle 120, the lifting component 42 can lift the filament bundle 120 to a preset height, ensuring that not only broken filaments and flyaways do not fly out of the dust-proof space, but also that the filaments do not have excessive tension or become too loose, thus ensuring a good forming effect.

[0042] In addition, such as Figure 1As shown, the dustproof assembly 10 also includes a dustproof cover 12, which is disposed at the top of the dustproof curtain 11. The dustproof cover 12 and the dustproof curtain 11 together form a dustproof space. By setting the dustproof cover 12, the dustproof effect can be further improved. Furthermore, the top of the dustproof curtain 11 affects the input and output of the workpiece 100 and also facilitates the fixing of the dustproof curtain 11, ensuring good performance.

[0043] Specifically, such as Figure 1 As shown, the drive mechanism 20 includes a drive component 21 and a sliding component 22. Both the drive component 21 and the sliding component 22 are mounted on the dust cover 12. The sliding component 22 is connected to the dust curtain 11. The drive component 21 can drive the sliding component 22 to move the dust curtain 11 to open and close the dustproof space. Both the drive component 21 and the sliding component 22 are mounted on the dust cover 12 (the dust cover 12 is set at a preset position and can be fixed by means of hoisting or direct installation), ensuring good stability and facilitating installation. The sliding component 22 ensures the smoothness of the dust curtain 11 during opening and closing.

[0044] Specifically, the sliding assembly 22 includes a slide rail and a slider. The slide rail is located at the bottom of the dust cover 12 and is arranged circumferentially around the dust cover 12. The dust curtain 11 is connected to the bottom of the slider, and the slider is slidably connected to the slide rail. Since the slide rail is arranged circumferentially around the bottom of the dust cover 12, the dust curtain 11 can open and close circumferentially around the dust cover 12, thereby ensuring the sealing of the top of the dustproof space. The top of the dust curtain 11 is directly connected to the slider, and the slider is slidably connected to the slide rail, which also ensures the convenience of installation and the smoothness of sliding.

[0045] It should be noted that the four corners at the bottom of the dust cover 12 are rounded to ensure the smooth opening and closing of the dust curtain 11. The corners of the guide rail are also rounded, with a bending radius R of approximately 250mm. Furthermore, the drive unit 21 is a motor with the following main parameters: 260L (model or specification), 220V (rated voltage 220 volts), and 85W (rated power 85 watts). Further explanation is that the opening and closing method of the dust curtain 11 can be adjusted according to actual needs. One side can be fixed to a preset position, and the drive unit 21 drives the other side to fold and retract towards the fixed side; alternatively, both sides can be fixed to preset positions, and the drive unit 21 drives the middle of the dust curtain 11 to fold and retract towards both sides. The choice can be made based on actual needs, and both methods are within the scope of this embodiment.

[0046] Furthermore, the dust curtain 11 is made of a flexible transparent material and is detachably connected to the sliding assembly 22. The transparent material allows for real-time observation of the usage of the yarn bundle 120; while the flexible material of the dust curtain 11 facilitates the opening and closing of the drive component 21, ensuring good performance. The detachable connection also facilitates subsequent cleaning or replacement of the dust curtain 11, and also facilitates maintenance of the sliding assembly 22. In this embodiment, the dust curtain 11 is made of anti-static PVC material.

[0047] In addition, such as Figure 1 As shown, the drive mechanism 20 also includes a control component 23, which is located on one side of the conveying mechanism 30 and is communicatively connected to the drive component 21. Since the drive component 21 is mounted on the dust cover 12, which is relatively high and difficult to open directly, the control component 23, being communicatively connected to the drive component 21, allows the operator to activate the drive component 21 with a single button press from the bottom surface. This further improves the convenience of opening and closing the dustproof space, making it simple, efficient, and safe.

[0048] The working process of the dustproof device in this embodiment is explained with reference to the accompanying drawings:

[0049] First, press the control component 23 to cause the drive component 21 to drive the dust curtain 11 to retract and fold, opening the dustproof space;

[0050] Next, the input table 31 transports the workpiece 100 to the balance table 41. The lifting component 42 drives the balance table 41 to rise to the preset position. Then, the control component 23 is pressed again to open the dust curtain 11 and close the dustproof space. As the operation continues, the lifting component 42 evenly lifts the workpiece 100 into the dustproof space.

[0051] Finally, when the operation is completed, the lifting component 42 lowers the tray 110 to be flush with the output table 32, and the conveying surface 411 transfers the tray 110 to the output surface 321, from which it is transferred.

[0052] In summary, the dustproof device in this embodiment is not only simple in structure, but also can automatically fold or open the dustproof curtain 11. While ensuring the dustproof effect, it can fully release manpower. The highly automated operation can improve work efficiency and reduce safety hazards.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
