Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to an adjustable positioning device for nozzles. Background Technology

[0002] The tobacco stem rehumidifier is a key piece of equipment in the tobacco processing production line. Its main function is to humidify and heat the tobacco stems through a mixture of steam and water, aiming to improve the toughness and processing characteristics of the tobacco stems and lay the foundation for subsequent processes.

[0003] In existing technology, tobacco stem rehumidification machines used in tobacco processing workshops typically have humidifying nozzles at the inlet end of their drums. These nozzles spray a mixture of steam and water to further wet the passing tobacco stems. However, current nozzle installation methods have significant drawbacks: they generally lack a stable and reliable dedicated positioning device. Under the influence of vibration and humid heat during long-term equipment operation, the nozzles are prone to loosening and displacement, causing their spray angle to tilt. Once the spray angle is inaccurate, the mixing medium cannot accurately and evenly cover and penetrate the tobacco stem material, resulting in a significant reduction in the moisturizing effect and directly affecting the subsequent processing quality and yield of the tobacco stems.

[0004] Currently, the industry lacks an effective solution to this problem, which has become a technical bottleneck restricting the stability and efficiency of the tobacco stem rehydration process. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable positioning device for nozzles, which provides stable support for the nozzles and allows for precise adjustment, thereby solving the problem of inconvenient nozzle positioning.

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

The adjusting rod is selectively fixed to the connecting fixing plate, and one end of the adjusting rod is axially positioned with the connecting fixing plate in the axial direction of the adjusting rod. The other end of the adjusting rod is fixedly connected to the positioning part, which is a U-shaped plate with a mounting groove for placing the nozzle. A cover plate is detachably connected to the positioning part, so that the cover plate and the groove wall of the mounting groove form a mounting through hole.

[0008] As an optional technical solution for the adjustable positioning device for the nozzle, the connecting fixing plate has an L-shaped structure. The long side of the connecting fixing plate is used to connect to the tobacco stem rehumidifier, and the short side of the connecting fixing plate has an adjustment hole through which the adjustment rod passes.

[0009] As an optional technical solution for the adjustable positioning device for the nozzle, the adjusting rod is a screw rod, and two nuts are screwed onto the adjusting rod, with the two nuts respectively located on both sides of the adjusting hole.

[0010] As an optional technical solution for an adjustable positioning device for a nozzle, the adjusting hole and the adjusting rod are fitted with a clearance.

[0011] As an optional technical solution for the adjustable positioning device for the nozzle, at least one anti-detachment plate is fixedly provided in the mounting groove. The anti-detachment plate and the side wall of the mounting groove form a slot, and the groove wall can match and fit with the outer wall of the nozzle.

[0012] As an optional technical solution for an adjustable positioning device for nozzles, the anti-detachment plate is fixed to the bottom of the mounting groove, and the anti-detachment plate extends along the depth direction of the mounting groove.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figures 1 to 5 As shown, this utility model provides an adjustable positioning device for nozzles, used to position nozzles on a tobacco stem rehumidifier. The adjustable positioning device includes a connecting fixing plate 1, an adjusting rod 2, and a positioning part 3. The connecting fixing plate 1 is fixedly connected to the tobacco stem rehumidifier. The adjusting rod 2 is selectively fixed to the connecting fixing plate 1, with one end of the adjusting rod 2 axially positioned with the connecting fixing plate 1 in the axial direction of the adjusting rod 2. The other end of the adjusting rod 2 is fixedly connected to the positioning part 3, which is a U-shaped plate with a mounting groove 31 for placing the nozzle. A cover plate 32 is detachably connected to the positioning part 3, so that the cover plate 32 and the groove wall of the mounting groove 31 form a mounting through hole. Specifically, the connecting fixing plate 1 is fixedly connected to the inlet end of the tobacco stem rehumidifier.

[0031] The nozzle is fixed to the tobacco stem rehumidifier via an adjustable positioning device and a connecting plate 1, ensuring stable installation. The adjusting rod 2 can be selectively fixed to the connecting plate 1, allowing adjustment of the height and angle of the positioning part 3, thus flexibly adjusting the nozzle's spray direction. The positioning part 3 is a U-shaped plate with a mounting groove 31 and a removable cover plate 32, forming a stable mounting through hole for reliably fixing the nozzle. This structure solves the problem of spray angle tilting caused by the lack of a positioning mechanism, ensuring the nozzle is always stably aligned with the roller inlet, improving the working efficiency of the tobacco stem rehumidifier. Simultaneously, the removable cover plate 32 facilitates quick nozzle installation and maintenance, reducing structural complexity and simplifying operation.

[0032] In this embodiment, a humidifying nozzle is used as an example.

[0033] In this embodiment, the connecting and fixing plate 1 has an L-shaped structure. The long side of the connecting and fixing plate 1 is used to connect to the tobacco stem rehumidifier, and the short side of the connecting and fixing plate 1 has an adjustment hole 11 through which the adjustment rod 2 passes. Specifically, the long side of the connecting and fixing plate 1 is welded to the outer surface of the tobacco stem rehumidifier.

[0034] The L-shaped structure of the connecting fixing plate 1 restricts the connection of the long side to the tobacco stem rehumidifier, while the short side has an adjustment hole 11 through which the adjustment rod 2 passes. The L-shaped design facilitates welding or fixing to the connection surface of the tobacco stem rehumidifier, providing a stable support base and enhancing the stability and ease of installation of the adjustable positioning device for the nozzle. The cooperation between the adjustment hole 11 and the adjustment rod 2 enables the movement and rotation of the adjustment rod 2 on the connecting fixing plate 1, providing a basis for adjusting the height and angle of the nozzle. This allows for precise control of the direction of the sprayed water flow, preventing nozzle tilting and ensuring effective spraying of water onto the tobacco stem material, thus improving the adaptability and adjustment accuracy of the adjustable positioning device for the nozzle.

[0035] Furthermore, the adjusting rod 2 is a screw rod, and two nuts 21 are screwed onto the adjusting rod 2, with the two nuts 21 respectively located on both sides of the adjusting hole 11.

[0036] By tightening or loosening the nut 21, the adjusting rod 2 can be quickly locked or released, enabling rapid adjustment and fixation of the height and angle of the positioning part 3. The combination of the screw and the nut 21 provides mechanical locking force, ensuring that the nozzle position is stable and reliable after adjustment, and preventing loosening due to vibration or long-term use. This design simplifies the operation steps, allowing adjustment to be completed without additional tools, reducing the difficulty of operation, and improving adjustment efficiency.

[0037] When the two nuts 21 are rotated and the distance between them is increased, the two nuts 21 are spaced apart from the short side of the connecting fixing plate 1, thereby releasing the adjusting rod 2. When the two nuts 21 are rotated and the distance between them is decreased, the two nuts 21 clamp the short side of the connecting fixing plate 1 from both sides, thereby locking the adjusting rod 2.

[0038] In this embodiment, the adjusting hole 11 and the adjusting rod 2 are fitted with a clearance.

[0039] The clearance fit allows the adjusting rod 2 to move and rotate freely within the adjusting hole 11, providing adjustment flexibility and facilitating smooth adjustment of the nozzle position. Simultaneously, after the nut 21 is tightened, the clearance fit reduces loosening, ensuring a secure connection between the adjusting rod 2 and the connecting fixing plate 1. This guarantees the stability of the adjustable positioning device for the nozzle even under vibration, thus ensuring long-term nozzle alignment accuracy and enhancing the overall structural stability and durability.

[0040] For example, at least one anti-detachment plate 33 is fixedly provided in the mounting groove 31. The anti-detachment plate 33 and the side wall of the mounting groove 31 form a retaining groove 34, and the groove wall of the retaining groove 34 can match and fit with the outer wall of the nozzle. Specifically, there are two anti-detachment plates 33, and the two anti-detachment plates 33 are symmetrically arranged about the center of the retaining groove 34. There are two retaining plates 33 in the tube part of the nozzle, and each tube part is matched and engaged in one retaining groove 34.

[0041] The anti-detachment plate 33 and the mounting groove 31 sidewall form a retaining groove 34 that fits snugly against the outer wall of the nozzle, effectively preventing the nozzle from falling off or shifting during operation. This improves the reliability and safety of the adjustable positioning device for the nozzle, ensures the stability of the nozzle during operation, avoids spray deviation caused by nozzle loosening, and improves the uniformity and reliability of the tobacco stem rehumidifier. The design of the retaining groove 34 also facilitates the initial positioning of the nozzle, helping to reduce installation time.

[0042] Furthermore, the anti-detachment plate 33 is fixed to the bottom of the mounting groove 31, and the anti-detachment plate 33 extends along the depth direction of the mounting groove 31.

[0043] The anti-detachment plate 33, extending from the bottom of the groove, provides additional support for the nozzle, preventing it from moving in the depth direction. This structure enhances the mechanical strength of the anti-detachment plate 33, improves the fixing effect of the slot 34, ensures the nozzle remains stable under vibration or impact conditions, and ensures the nozzle will not detach from the mounting slot 31 during long-term use, further improving the reliability of the adjustable positioning device for the nozzle. Simultaneously, the anti-detachment plate 33, extending along the depth direction, provides a larger contact area, further stabilizing the nozzle and improving overall durability.

[0044] In this embodiment, both ends of the positioning part 3 are bent with winglets 35, and the cover plate 32 is attached to and detachably connected to the winglets 35.

[0045] The wing 35 increases the connection area, allowing the cover plate 32 to evenly press the nozzle, ensuring that the nozzle is stably pressed into the mounting groove 31 and preventing the nozzle from loosening; the detachable connection facilitates the quick opening and closing of the cover plate 32, making it convenient for nozzle inspection, replacement or maintenance, reducing downtime, and improving the working efficiency and convenience of the adjustable positioning device for the nozzle.

[0046] Furthermore, the cover plate 32 and the wing 35 are connected by bolts 36.

[0047] The bolt 36 connection is a simple and reliable fastening method that allows for quick tightening and loosening, providing sufficient clamping force to secure the nozzle. This design ensures that the cover 32 will not loosen under vibration, ensures that the cover 32 is tightly pressed against the nozzle, effectively preventing the nozzle from falling off, and facilitates operation with standard tools, reducing maintenance costs.

[0048] Specifically, the edges of the cover plate 32 and the wing 35 are aligned, and the bolts 36 pass through the reserved holes in the wing 35 and the cover plate 32 for fixing.

[0049] In this embodiment, the opening of the mounting groove 31 faces upward, and the other end of the adjusting rod 2 is fixed to the bottom end of the positioning part 3. Specifically, the adjusting rod 2 is welded and fixed to the outer wall of the positioning part 3.

[0050] The upward-facing opening facilitates the placement and removal of the nozzle, simplifying the installation process. The adjusting rod 2 supports the positioning part 3 at the bottom, providing a stable suspension point and stabilizing the center of gravity of the overall structure. This allows for easy adjustment of the nozzle height and angle via the adjusting rod 2, ensuring that the nozzle spray direction is accurately aligned with the roller inlet, reducing deviations during the adjustment process, and improving the working efficiency of the tobacco stem rehumidifier.

[0051] For example, the adjusting rod 2 extends axially in the vertical direction.

[0052] The vertical adjustment is aligned with the direction of gravity, making it easier to control the nozzle height via the adjustment rod 2, thus making the adjustment process more intuitive and stable. This design optimizes the adjustment mechanism, ensuring that the vertical adjustment of the nozzle simplifies the operation, avoids complex angle calculations, improves the intuitiveness and efficiency of the adjustment, and further guarantees the working effect of the tobacco stem rehumidifier.

[0053] This embodiment also provides an adjustable positioning method for the nozzle, applied to the aforementioned adjustable positioning device for the nozzle, comprising the following steps: placing the nozzle into the mounting groove 31 so that the nozzle outlet is aligned with the roller inlet on the tobacco stem rehumidifier; then covering the mounting groove 31 with the cover plate 32 so that the roller inlet is housed in the mounting through hole; by rotating and axially moving the adjusting rod 2 relative to the connecting fixing plate 1, the adjustment of the nozzle support height and angle can be completed, so that the nozzle is always stably aligned with the roller inlet.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
