Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a pneumatic feeding air inlet valve and a rotary drum feeder. Background Technology

[0002] The main function of the air intake valve for wind-powered tobacco feeding is to filter and protect the equipment. The air intake valve for wind-powered tobacco feeding is usually located at the air inlet of the wind-powered tobacco feeding system. Its main purpose is to filter impurities. Through the action of negative pressure, the air intake valve for wind-powered tobacco feeding can filter out dust, impurities and other contaminants in the air and tobacco, preventing these impurities from entering the feeding system and thus protecting the precision components inside the system from damage.

[0003] The existing design of the wind-powered tobacco feeding air inlet valve has a single-layer mesh design, which is prone to leakage during air intake. This causes the tobacco to enter the negative pressure generating element, resulting in tobacco loss and instability of the negative pressure system.

[0004] Therefore, it is urgent to design a wind-powered inlet valve for wire feeding and a rotary drum wire feeder to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a wind-powered tobacco feeding air inlet that enhances the blocking effect on tobacco during air intake, preventing tobacco from leaking out and entering the negative pressure generating element, ensuring the stable operation of the negative pressure system, and reducing tobacco loss.

[0006] Another objective of this invention is to provide a rotary drum tobacco feeder, wherein the negative pressure system has improved operational stability and reduced tobacco loss.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The wind-powered filament feeding inlet valve includes:

[0009] A fixed door panel is installed in the wire feeding pipeline. The fixed door panel is provided with multiple rows of first through holes, and each row of the first through holes is spaced apart along the second direction.

[0010] The movable door panel slides in conjunction with the fixed door panel in a first direction. The movable door panel is provided with multiple rows of second through holes. Each row of the second through holes is spaced apart along the second direction. The multiple rows of the first through holes and the multiple rows of the second through holes are staggered in the second direction. The first direction and the second direction are perpendicular.

[0011] As an alternative, in the second direction described above, multiple rows of the first through holes and multiple rows of the second through holes are alternately arranged.

[0012] As an alternative, one of the fixed door panel and the movable door panel is provided with a slide groove extending along the first direction, and the other is provided with a slide rail extending along the first direction, wherein the slide rail and the slide groove are slidably engaged.

[0013] As an optional solution, the aforementioned wind-powered wire-feeding air intake valve also includes a lead screw, which extends along the aforementioned first direction and is pivotally connected at both ends to the aforementioned fixed door panel. A connecting piece is protruding from the aforementioned movable door panel, and the connecting piece is threadedly engaged with the aforementioned lead screw.

[0014] As an alternative, the end of the aforementioned lead screw is provided with an operating part.

[0015] As an optional solution, two slides are provided, and the two slides are spaced apart in the second direction.

[0016] As an optional solution, the aforementioned wind-powered yarn feeding inlet valve also includes a cleaning component, which includes:

[0017] A guide member extends along the first direction and is installed on the fixed door panel, and a limit part is provided at each end of the guide member;

[0018] The cleaning component slides in conjunction with the guide component, extends along the second direction, and can clean the fixed door panel and the movable door panel when sliding along the guide component.

[0019] As an alternative, the cleaning component also includes a handle connected to the side of the cleaning component facing away from the movable door panel.

[0020] As an optional solution, the above-mentioned cleaning components include:

[0021] The sliding part slides in conjunction with the aforementioned fixed door panel;

[0022] A brush is attached to the side of the sliding part near the movable door panel.

[0023] A rotary drum tobacco feeder, as an optional solution, includes a tobacco feeding pipeline, a negative pressure generator, and the aforementioned pneumatic tobacco feeding inlet valve. The pneumatic tobacco feeding inlet valve is installed in the tobacco feeding pipeline, and the negative pressure generator is used to draw air from the tobacco in the tobacco feeding pipeline through the pneumatic tobacco feeding inlet valve.

[0024] The beneficial effects of this utility model are as follows:

[0025] This utility model provides a wind-powered tobacco feeding air inlet door. By setting up a double-layer door panel, namely a fixed door panel and a movable door panel, and the first through hole and the second through hole do not overlap when the movable door panel and the fixed door panel slide relative to each other, when the tobacco passes through this point, the negative pressure generating component generates negative pressure. The airflow must bend after passing through the first through hole and then pass through the second through hole. Dust and other particles are sucked out with the airflow. Since the tobacco is relatively large, it cannot pass through the gap between the fixed door panel and the movable door panel, thus preventing the tobacco from being sucked away and preventing the tobacco from entering the negative pressure system, ensuring the stable operation of the negative pressure system, and reducing tobacco loss. In addition, the sliding cooperation of the fixed door panel and the movable door panel can adjust the negative pressure intensity on the tobacco. That is, when using the same intensity of negative pressure for adsorption, when the first through hole and the second through hole overlap more in the first direction, the adsorption force is greater, and when they overlap less, the adsorption force is smaller.

[0026] This utility model also provides a rotary drum tobacco feeder, including a tobacco feeding pipeline and a negative pressure generator. The aforementioned pneumatic tobacco feeding inlet valve is installed in the tobacco feeding pipeline, and the negative pressure generator is used to draw air from the tobacco shreds in the tobacco feeding pipeline through the pneumatic tobacco feeding inlet valve. By adopting the Shanghai Fengsong tobacco feeding inlet valve, the negative pressure system of this rotary drum tobacco feeder has improved operational stability and reduced tobacco shred loss.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] In the description of this embodiment, the terms "upper," "lower," "left," and "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.

[0040] This embodiment provides a pneumatic tobacco feeding air inlet valve. During air intake, the valve enhances its blocking effect on the tobacco, preventing it from leaking out and entering the negative pressure generating element, thus ensuring the stable operation of the negative pressure system and reducing tobacco loss. Figure 1As shown, the wind-powered air intake valve includes a fixed door plate 10 and a movable door plate 20. The fixed door plate 10 is disposed in the wire feeding tube and has multiple rows of first through holes 11, each row of first through holes 11 being spaced apart along a second direction (Y direction in the figure). The movable door plate 20 slides in conjunction with the fixed door plate 10 in a first direction (X direction in the figure, where X direction is perpendicular to Y direction). The movable door plate 20 has multiple rows of second through holes 21, each row of second through holes 21 being spaced apart along the first direction. The multiple rows of first through holes 11 and multiple rows of second through holes 21 are staggered in the second direction. It should be noted that since the wire feeding tube is cylindrical, the second direction is not a strictly linear direction; see [reference needed]. Figure 4 The Y direction is the arc direction that adapts to the edge of the wire feeding tube cross-section. In other embodiments, such as when the cross-section of the wire feeding tube has other shapes, the definition of the second direction can be understood adaptively.

[0041] The aforementioned wind-powered tobacco inlet valve, by setting up a double-layer door panel, namely a fixed door panel 10 and a movable door panel 20, and the first through hole 11 and the second through hole 21 do not overlap when the movable door panel 20 and the fixed door panel 10 slide relative to each other, when the tobacco passes through this point, the negative pressure generator produces negative pressure. The airflow must bend after passing through the first through hole 11 and then pass through the second through hole 21. Dust and other particles are sucked out with the airflow. Since the tobacco is relatively large, it cannot pass through the gap between the fixed door panel 10 and the movable door panel 20, thus preventing the tobacco from being sucked away and preventing the tobacco from entering the negative pressure system, ensuring the stable operation of the negative pressure system, and reducing tobacco loss. In addition, the sliding cooperation between the fixed door panel 10 and the movable door panel 20 can adjust the negative pressure intensity on the tobacco. That is, when using the same intensity of negative pressure for adsorption, when the first through hole 11 and the second through hole 21 overlap more in the first direction, the adsorption force is greater, and when they overlap less, the adsorption force is smaller.

[0042] Optionally, such as Figure 1 and Figure 2 As shown, in the second direction, multiple rows of first through holes 11 and multiple rows of second through holes 21 are alternately arranged. This ensures that the airflow is dispersed quickly to the maximum extent, that is, a row of second through holes 21 is arranged next to each row of first through holes 11, so that the airflow can be quickly bent and sucked out.

[0043] In other embodiments, two columns of second through holes 21 may be provided between two adjacent columns of first through holes 11. Of course, there are many other different arrangements, which will not be listed here.

[0044] Optionally, such as Figure 1 and Figure 3As shown, one of the fixed door panel 10 and the movable door panel 20 is provided with a slide groove 22 extending along the first direction, and the other is provided with a slide rail 12 extending along the first direction. The slide rail 12 is slidably engaged with the slide groove 22. Through the above arrangement, the sliding engagement of the fixed door panel 10 and the movable door panel 20 is achieved.

[0045] Optionally, two slides 22 are provided, and the two slides 22 are spaced apart in the second direction.

[0046] In this embodiment, the first direction is the vertical direction. This is to ensure that the movable door panel 20 does not move up and down after being adjusted to its position. Figure 1 and Figure 3 As shown, the wind-powered wire-feeding air intake valve also includes a lead screw 31, which extends along a first direction and is pivotally connected to the fixed door panel 10 at both ends. A connecting member 23 protrudes from the movable door panel 20 and is threadedly engaged with the lead screw 31. With the above configuration, turning the lead screw 31 causes the connecting member 23 to move along the first direction due to the guiding effect of the slide rail 12. The connecting member 23 causes the movable door panel 20 to slide relative to the fixed door panel 10. After the movable door panel 20 is adjusted to the correct position, the position of the connecting member 23 will not change due to the self-locking effect of the thread of the lead screw 31, thereby fixing the position of the movable door panel 20.

[0047] Optionally, two pivot seats 13 are provided on the fixed door panel 10, and the two ends of the lead screw 31 are pivotally connected to the two pivot seats 13 respectively.

[0048] In other embodiments, such as when the first direction is horizontal, in order to stabilize the position of the movable door panel 20 after adjustment, a damping structure can be provided in the slide groove 22, and the friction of the damping structure can be overcome with a little force to slide.

[0049] Optionally, such as Figure 3 As shown, the end of the lead screw 31 is provided with an operating part 32. This allows the operator to easily turn it. Specifically, the operating part 32 is constructed as a cylindrical body with a diameter larger than that of the lead screw 31 and an anti-slip structure on its outer periphery. In other embodiments, the operating part 32 may also be polygonal, such as hexagonal, to facilitate operation with a wrench.

[0050] After prolonged use, dust or a small amount of tobacco residue will inevitably accumulate on the fixed door panel 10 and the movable door panel 20, hindering airflow. To solve this problem, such as... Figure 1 and Figure 4As shown, the wind-powered wire feeding inlet valve also includes a cleaning assembly 40. The cleaning assembly 40 includes a guide member 41 and a cleaning member 43. The guide member 41 extends along a first direction and is installed on the fixed door panel 10. Limiting portions 42 are provided at both ends of the guide member 41. The cleaning member 43 slides with the guide member 41 and extends along a second direction, enabling it to clean both the fixed door panel 10 and the movable door panel 20 while sliding along the guide member 41. Thus, the operator can hold the cleaning member 43 and slide it along the guide member 41 to complete the cleaning of both the fixed door panel 10 and the movable door panel 20. It should be noted that... Figure 4 The component inside the cleaning component 43 is for illustrative purposes only. It can be either a fixed door panel 10 or a movable door panel 20. A more reasonable configuration is that the movable door panel 20 is raised to a higher position, so that the first through hole 11 and the second through hole 21 are completely offset in the first direction. That is, the first through hole 11 and the second through hole 21 are completely exposed in the direction perpendicular to the illustration. When the cleaning component 43 slides up and down, the first through hole 11 and the second through hole 21 can be cleaned more thoroughly.

[0051] Optionally, such as Figure 1 and Figure 4 As shown, the cleaning assembly 40 also includes a handle 44, which is attached to the side of the cleaning component 43 facing away from the movable door panel 20. Thus, the operator can hold the handle 44 to easily slide the cleaning component 43.

[0052] Optionally, such as Figure 4 As shown, the cleaning component 43 includes a sliding part 431 and a brush 432. The sliding part 431 is slidably engaged with the fixed door panel 10; the brush 432 is connected to the sliding part 431 on the side near the movable door panel 20. With this configuration, the brush 432 can achieve a relatively thorough cleaning effect on both the fixed door panel 10 and the movable door panel 20. In other embodiments, the brush 432 can also be replaced by a sponge or the like, which is not limited here.

[0053] In this embodiment, the fixed door plate 10 is connected to the wire feeding pipeline by connecting bolts. In other embodiments, the fixed door plate 10 may also be part of the wire feeding pipeline body, which is not limited here.

[0054] This embodiment also provides a rotary drum tobacco feeder, including a tobacco feeding pipeline, a negative pressure generator, and the aforementioned pneumatic tobacco feeding inlet valve. The pneumatic tobacco feeding inlet valve is disposed in the tobacco feeding pipeline, and the negative pressure generator is used to draw air from the tobacco shreds in the tobacco feeding pipeline through the pneumatic tobacco feeding inlet valve. By employing the aforementioned pneumatic tobacco feeding inlet valve, the negative pressure system of this rotary drum tobacco feeder achieves improved operational stability and reduces tobacco shred loss.

[0055] 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 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. 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.
