Description

Technical Field

[0001] This utility model relates to the field of vibratory groove technology, and in particular to a vibratory groove valve device. Background Technology

[0002] In automated production lines in the tobacco industry, vibrating troughs with valves are commonly used. The main function of the valve is to automatically discharge material from the vibrating trough, thereby collecting material or changing its movement path. The valve of a vibrating trough typically consists of a rectangular discharge port on the bottom plate of the trough and a rotating plate. The rotation of the rotating plate is achieved by a series of electronically controlled components such as a cylinder, a detection switch, a solenoid valve, and air pipes. The rotating plate is a flat plate, and the cylinder is mounted on the bottom plate near the discharge port. Under the control of the cylinder, the rotating plate rotates around its hinge with the bottom plate, opening and closing the discharge port.

[0003] Currently, in order to enhance the sealing effect of the rotating plate on the leakage port, a sealing strip is set between the rotating plate and the corresponding edge of the leakage port. However, since the rotating plate is hinged to the bottom plate of the trough on one side, when the rotating plate rotates around the hinge axis to seal the leakage port, a wedge-shaped gap will appear on the edge adjacent to the hinge side. During the process of conveying tobacco materials such as tobacco shreds in the vibrating trough, the tobacco materials such as tobacco shreds will leak through the gap, causing material waste. Sometimes, it will also leak into another vibrating trough, causing the leaked tobacco materials to mix with tobacco materials of another brand, resulting in serious quality accidents. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a vibrating groove valve device to solve the problem of material waste or material mixing accidents caused by the leakage of tobacco materials through the valve gap in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a vibrating groove valve device, including a rectangular material outlet and a rotating plate formed on the bottom plate of the groove, a hinge shaft provided below one side edge of the rotating plate, linear sliders connected to both ends of the hinge shaft, a wedge-shaped guide rail provided on the bottom plate of the groove, and the linear slider slidingly engaging with the wedge-shaped guide rail; it also includes a cylinder set on the bottom plate of the groove, the push rod of the cylinder being hinged to the rotating plate, and the movement direction of the push rod forming an acute angle with the extension direction of the wedge-shaped guide rail.

[0006] Optionally, guide rollers are provided on both sides of the bottom of the rotating plate, and arc-shaped guide grooves are provided on both sides corresponding to the bottom plate of the groove. The radius of curvature of the arc-shaped guide grooves matches the rotation trajectory of the rotating plate. This is used to limit the lateral displacement of the rotating plate during the sliding process and reduce frictional resistance.

[0007] Optionally, the inclination angle of the wedge-shaped guide rail matches the rotation trajectory of the rotating plate, and the extension direction of the wedge-shaped guide rail is perpendicular to the hinge axis. The wedge-shaped guide rail allows the hinge axis and the rotating plate to move as a whole.

[0008] Optionally, the inclination angle of the wedge-shaped guide rail is 5°-10°. The sliding distance of the linear slider is converted into the movable distance in both directions of the hinge axis by the inclination angle.

[0009] Optionally, the cylinder push rod is connected to the rotating plate via a spherical hinge. This allows the push rod to rotate relative to the rotating plate as it rotates, preventing the cylinder from jamming.

[0010] Optionally, the axis of the cylinder forms an angle of 15°-25° with the plane of the bottom plate of the groove. The inclined cylinder provides rotational torque for the rotating plate to rotate and close around the hinge axis, and provides lateral thrust for the linear slider to slide along the wedge-shaped guide rail.

[0011] Optionally, the rotating plate is a ferromagnetic material, and a sealing groove is formed on the edge of the rotating plate. A sealing strip is provided in the sealing groove, and a permanent magnet is provided on the edge of the discharge port corresponding to the position of the sealing strip. This further ensures the sealing effect between the rotating plate and the discharge port.

[0012] The beneficial effects of this utility model are:

[0013] This invention connects linear sliders to both ends of a hinge shaft, and provides wedge-shaped guide rails on the bottom plate of the groove that match the linear sliders. Under the push of an inclined cylinder, the inclined thrust of the push rod is decomposed into rotational torque and lateral thrust, which drives the rotating plate to rotate and close around the hinge shaft. At the same time, it pushes the linear sliders to slide, causing the rotating plate to move laterally as a whole. By using a structure similar to a "floating hinge" to provide motion compensation for the rotating plate, the side edge is made to fit with the edge of the leakage port, thereby solving the problem of material waste or material mixing accidents caused by tobacco material leakage through the gap of the valve in the prior art.

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0023] like Figures 1-6 As shown, this utility model discloses a vibratory trough gate device, comprising a rectangular material outlet on a trough bottom plate 1 and a rotating plate 11. The trough bottom plate 1 is the bottom flat plate for conveying materials in the vibratory trough. A hinge shaft 12 is fixedly connected to the lower edge of one side of the rotating plate 11. Linear sliders 13 are connected to both ends of the hinge shaft 12. The hinge shaft 12 and the linear sliders 13 are rotatably connected, thereby driving the rotating plate 11 to rotate. A wedge-shaped guide rail 14 is fixedly connected to the trough bottom plate 1. The linear sliders 13 slide along the wedge-shaped guide rail 14, thereby driving the rotating plate 11 to move. The wedge-shaped guide rail 14 is fixedly connected to the trough bottom plate 1, and the linear sliders 13 can slide along the wedge-shaped guide rail 14. At the same time, the wedge-shaped guide rail 14 is provided with a limiting block to prevent the linear sliders 13 from derailing.

[0024] In this embodiment, a cylinder 15 is also included, which is mounted on the bottom plate 1 of the trough. Specifically, the cylinder 15 is connected to the bottom plate 1 of the trough via a support. The push rod of the cylinder 15 is hinged to the rotating plate 11. The direction of movement of the push rod forms an acute angle with the extension direction of the wedge-shaped guide rail 14. The body of the cylinder 15 is fixed on the cylinder support of the bottom plate 1 of the trough. Specifically, the push rod of the cylinder 15 is connected to the rotating plate 11 via a spherical hinge. The axis of the cylinder 15 forms an angle of 15°-25° with the plane of the bottom plate 1 of the trough. When the push rod of the cylinder extends, the inclined thrust of the push rod is decomposed into two components: one is the rotational torque, which drives the rotating plate 11 to rotate and close around the hinge axis 12; the other is the lateral thrust, which drives the linear slider 13 to slide along the wedge-shaped guide rail 14, so that the rotating plate 11 moves laterally in the material conveying direction (to the right in the figure). Due to the wedge angle, the rotating plate 11 moves vertically, preventing the rotating plate 11 from getting stuck in the leakage port. Correspondingly, when the cylinder push rod retracts, it drives the rotating plate 11 to rotate and open around the hinge axis 12, while simultaneously causing the rotating plate 11 to move laterally as a whole (to the left in the figure).

[0025] In this embodiment, guide rollers 16 are provided on both sides of the bottom of the rotating plate 11, and arc-shaped guide grooves 17 are provided on both sides of the bottom plate 1. Specifically, the arc-shaped guide grooves 17 are fixedly connected to the side plates on both sides of the bottom of the bottom plate 1 of the vibrating groove. The radius of curvature of the arc-shaped guide grooves 17 matches the rotation trajectory of the rotating plate 11, ensuring that the guide rollers 16 do not jam when rolling, thereby limiting the lateral displacement of the rotating plate 11 during the sliding process and reducing frictional resistance.

[0026] In this embodiment, the extension direction of the wedge-shaped guide rail 14 is perpendicular to the hinge shaft 12, and the inclination angle of the wedge-shaped guide rail 14 is 5°-10°. Specifically, the bottom surface of the linear slider 13 is provided with a groove that fits tightly with the protrusion on the wedge-shaped guide rail 14, restricting the linear slider 13 to slide only along the guide rail direction. This allows the linear slider 13 to slide along the wedge-shaped guide rail 14 when the rotating plate 11 rotates around the hinge shaft 12, forcing the rotating plate 11 to simultaneously generate a lateral displacement (perpendicular to the hinge shaft 12 direction). The direction of the lateral displacement is consistent with the gap compensation requirement, thereby reducing the problem of material waste or material mixing accidents caused by tobacco material leakage through the gaps of traditional valves. It should be understood that the two ends of the protrusion are provided with limiting blocks that abut against the end face of the linear slider 13 to limit the sliding distance of the linear slider 13 (hinge shaft 12). The sliding distance of the linear slider 13 is converted into the distance of the lateral and vertical movement of the hinge shaft 12 by the inclination angle.

[0027] In this embodiment, to further ensure the sealing effect between the rotating plate 11 and the discharge port, the rotating plate 11 is set as a ferromagnetic body, and a sealing groove is opened on the edge of the rotating plate 11. A sealing strip is provided in the sealing groove, and a permanent magnet is provided at the position of the sealing strip on the edge of the discharge port. When the rotating plate 11 is closed, the permanent magnet attracts the rotating plate 11, thereby tightly attracting the sealing strip to the edge of the discharge port, ensuring the sealing effect while also compensating for processing errors.

[0028] It should be understood that in this embodiment, lateral movement refers to the direction parallel to the bottom plate 1, while vertical movement refers to the direction perpendicular to the bottom plate 1. Correspondingly, lateral movement and vertical movement also refer to movement relative to the bottom plate 1. Lateral movement means that the overall movement direction is parallel to the bottom plate 1, and vertical movement means that the overall movement direction is perpendicular to the bottom plate 1.

[0029] The working principle of this utility model is as follows:

[0030] When the novel valve device of this utility model is in use, when the cylinder push rod extends, the inclined thrust of the push rod is decomposed into two components: one is the rotational torque, which drives the rotating plate 11 to rotate and close around the hinge axis 12; the other is the lateral thrust, which pushes the rotating plate 11 to move laterally in the material conveying direction through the linear slider 13 sliding along the wedge guide rail 14, and at the same time, completes the closing of the material leakage port of the rotating plate 11. Correspondingly, when the cylinder push rod retracts, the rotating plate 11 opens the material leakage port.

[0031] During this process, the wedge-shaped guide rail 14 structure enables the rotating plate 11 to simultaneously possess multiple degrees of freedom in rotation and lateral sliding. When the rotating plate 11 is closed, the angle of the push rod of the tilting cylinder drives the rotating plate 11 to rotate and move laterally. Due to the wedge angle, the rotating plate 11 moves vertically as a whole, preventing it from getting stuck in the discharge port. A structure similar to a "floating hinge" provides motion compensation for the rotating plate 11, achieving contact between the side of the rotating plate 11 and the edge of the discharge port, thereby reducing material leakage.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
