[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0029] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] This embodiment provides a valve device. Specifically, Figure 1 and Figure 2 As shown, the device includes a feeding rack 10 and a valve mechanism 20, wherein the feeding rack 10 is arranged on a supporting surface, and a feeding trough 11 is arranged at the top of the feeding rack 10; the valve mechanism 20 includes a gate 22, a driving member 23 and a sealing member 24, the top of the gate 22 is connected to the output end of the driving member 23, and the sealing member 24 is arranged at the bottom end of the gate 22. When the output end of the driving member 23 is extended in the vertical direction, the gate 22 can cut off the feeding trough 11 in a first direction, and the sealing member 24 can abut against the bottom of the feeding trough 11 to seal the gap between the gate 22 and the feeding trough 11, so that the material can be accumulated on one side of the gate 22.

[0033] In this device, the feed trough 11 can convey materials to the wire drying machine. Before entering the wire drying machine, the output end of the driving member 23 extends out and causes the gate 22 to cut off the feed trough 11 along the first direction (the width direction of the feed trough 11), and at this time, the sealing member 24 can block the gap between the bottom end of the gate 22 and the bottom of the feed trough 11, thereby temporarily cutting off the conveying of materials. At this time, the material can continue to accumulate and increase on one side of the gate 22, and will not continue to be conveyed from the gap between the gate 22 and the feed trough 11. When the accumulated material reaches a certain amount, the driving member 23 can drive the gate 22 and the sealing member 24 to separate from the bottom of the feed trough 11. At this time, the accumulated material can be conveyed to the wire drying machine at the same time, thereby effectively avoiding the problem of dry tobacco heads caused by the amount of material entering the wire drying machine being too thin, thereby improving the yield rate and work efficiency.

[0034] It is worth noting that in this embodiment, the driving member 23 is a cylinder, which has a simple structure, low price, is easy to install and use, and is conducive to simplifying the overall structure of the device and reducing the initial cost. In other embodiments, structures such as telescopic motors may also be selected, and no other restrictions are made in this embodiment. In addition, the sealing member 24 is an airbag, and airbags of different sizes and shapes can be selected according to actual needs to adapt to various blocking scenarios, and the flexibility and convenience of use are high.

[0035] In order to increase the material accumulation speed, such as Figure 1 and Figure 2As shown, the inner wall of the feed trough 11 is provided with a guide plate 12, which is inclined to reduce the width of the feed trough 11. In this structure, when the material passes through the guide plate 12, the material can be gathered along the inclined direction (extension direction) of the guide plate 12 due to the continuous reduction of the conveying width, so the material in the feed trough 11 can be quickly accumulated, thereby improving work efficiency.

[0036] In addition, when the seal 24 abuts against the bottom of the feed trough 11, the end of the guide plate 12 away from the side wall of the feed trough 11 can abut against the side of the gate 22. This arrangement can avoid the appearance of a gap between the guide plate 12 and the feed trough 11, thereby affecting the stacking speed of the material, thereby ensuring a good effect.

[0037] In addition, if Figure 1 As shown, guide plates 12 are provided on both sides of the feed trough 11 along the first direction. In this structure, the materials can be quickly gathered toward the middle through the guide plates 12 on both sides of the feed trough 11, and then enough materials can be quickly accumulated on one side of the gate 22, further improving the work efficiency and accumulation speed.

[0038] In addition, the guide plates 12 on both sides of the feed trough 11 along the first direction are symmetrically arranged, and are both detachably connected to the side walls of the feed trough 11. The two guide plates 12 are symmetrically arranged, which can ensure that the materials on both sides gather at the same rate, avoiding the situation where too much material is accumulated on one side and too little on the other side; at the same time, the detachable connection between the guide plates 12 and the side walls of the feed trough 11 is convenient for subsequent maintenance and replacement, and is also convenient for dark rotation when replacing the guide plates 12 with different inclination angles.

[0039] What needs to be explained here is that Figure 2 As shown, the guide plate 12 also includes a connecting portion 121, and the guide plate 12 can be detachably fixed to the side wall of the feeding trough 11 through the screw 40 and the connecting portion 121. The screw 40 is not only simple in structure, but also low in price, easy to install and has a good fixing effect. In other embodiments, bolts, pins, etc. can also be used instead of the screw 40.

[0040] Specifically, Figure 1As shown, the valve mechanism 20 also includes a bracket 21, and the bracket 21 includes a support rod 211 and a cross bar 212. Both ends of the cross bar 212 are connected to the support rod 211, and the other end of the support rod 211 is connected to the feed rack 10 and is arranged in the vertical direction. The cross bar 212 is located above the feed trough 11, and the driving member 23 is arranged on the cross bar 212. The gate 22 is movably arranged between the cross bar 212 and the bottom of the feed trough 11. By providing the bracket 21, the overall structure of the device can be simplified, and the driving member 23 can be easily installed. At the same time, the stability of the gate 22 when the driving member 23 drives the gate 22 to move can be improved to prevent the device from shaking; in addition, the cross bar 212 can also limit the moving space of the gate 22 in the vertical direction, thereby improving work efficiency.

[0041] In order to ensure that the gate 22 can smoothly move into the feeding trough 11, both sides of the gate 22 along the first direction are slidably connected to the bracket 21. This arrangement can not only improve the stability of the gate 22 during movement, but also ensure that both sides are slidably connected to the bracket 21, thereby ensuring the smoothness of the driving member 23 driving the gate 22 and reducing the movement resistance of the gate 22.

[0042] Specifically, Figure 1 and Figure 2 As shown, the valve device further includes a sliding assembly 30, which includes a slider 31 and a slide rail 32. The sliders 31 are provided on both sides of the gate 22 along the first direction, and the slide rail 32 is provided on the side of the support rod 211 close to the gate 22. The slider 31 is slidably connected with the slide rail 32. This arrangement can not only simplify the overall structure of the sliding assembly 30, but also facilitate the installation and fixing of the slider 31 and the slide rail 32, thereby reducing the manufacturing difficulty and manufacturing cost.

[0043] Furthermore, if Figure 2 As shown, connecting rods 25 are provided on both sides of the gate 22 along the first direction, and a fixing plate 26 is provided at one end of the connecting rod 25 away from the gate 22, and the fixing plate 26 is detachably connected to the slider 31. The connecting rod 25 and the fixing plate 26 simplify the structure of installing the slider 31 on both sides of the gate 22, thereby reducing the processing difficulty and manufacturing cost. In addition, the detachable connection method also facilitates the subsequent maintenance and replacement of the slider 31, thereby improving practicality. It should be noted that, in the present embodiment, the fixing plate 26 is locked to the slider 31 by a screw 40. The screw 40 is not only simple in structure, but also low in price and small in size, which is convenient for installation on the slider 31 and has a good fixing effect. In other embodiments, bolts, pins, etc. may also be used instead of the screw 40.

[0044] In addition, if Figure 2As shown, a fixing block 213 is provided on one side of the support rod 211 close to the gate 22, and the slide rail 32 is detachably connected to the fixing block 213. The fixing block 213 not only simplifies the inner structure of the support rod 211, but also avoids the situation of directly processing the slide rail 32 on the inner side of the support rod 211, thereby reducing the processing difficulty and manufacturing cost. At the same time, the fixing block 213 is arranged on the support rod 211, which also ensures the stability during the sliding process. In addition, the detachable connection method also facilitates the subsequent maintenance and replacement of the slide rail 32, thereby improving the practicality. It should be noted that, in the present embodiment, the slide rail 32 is locked to the fixing block 213 by a screw 40. The screw 40 is not only simple in structure, but also low in price and small in size, which is convenient for installing and fixing the slide rail 32. In other embodiments, bolts, pins, etc. can also be used instead of the screw 40.

[0045] The working process of the valve device in this embodiment is described with reference to the accompanying drawings:

[0046] First, the device is placed at the feed inlet of the silk drying machine, and materials are laid in the feed trough 11;

[0047] Secondly, the driving member 23 is opened, and its output end can drive the gate 22 and the sealing member 24 to cut off the feeding trough 11 along the first direction, so that the materials can be quickly accumulated under the action of the guide plate 12;

[0048] Finally, when the materials are accumulated to a sufficient amount, the output end of the driving member 23 is retracted, the gate 22 is opened, and the accumulated materials can enter the feed port of the silk drying machine together, thereby completing the normal operation.

[0049] In summary, the valve device in this embodiment can increase the instantaneous flow rate of the material entering the tobacco dryer, thereby avoiding problems such as dry tobacco ends caused by the amount of material entering the tobacco dryer being too thin, while ensuring good operating efficiency.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
