[0032] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, but cannot be understood as a limitation of the present disclosure.
[0033] As shown in the drawings, the present disclosure provides a discharging device 1 comprising a housing 2 and a push plate 31. Figures 1 to 3
[0034] The housing 2 has an accommodating space inside for accommodating materials 7, the top of the housing 2 has a feeding port 21 communicating with the accommodating space, and one side of the housing 2 is provided with a discharging port 22 communicating with the accommodating space. The push plate 31 is movably arranged in the accommodating space and can be close to or away from the discharging port 22.
[0035] When the materials 7 enter the accommodating space through the feeding port 21, the space between the discharging port 22 and the push plate 31 of the housing 2 is a semi-enclosed space, which communicates with the discharging port 22 and thus with the open space outside the housing 2.
[0036] Specifically, the housing 2 in the present disclosure can be a hollow cuboid, wherein the feeding port 21 can be arranged at the top of the housing 2, the discharging port 22 can be arranged on one side of the housing 2, and the push plate 31 can be arranged in the accommodating space formed by the housing 2, and the push plate 31 is arranged at the end of the feeding port 21 away from the discharging port 22. In the present disclosure, the space between the discharging port 22 and the push plate 31 of the housing 2 can only communicate with the open space outside through the discharging port 22 and the feeding port 21.
[0037] The present disclosure sets the discharging device 1 with the housing 2 and the push plate 31 to reduce the influence of external airflow on the inside of the accommodating space by using the semi-enclosed space formed by the housing 2 and the push plate 31, so that the materials 7 and dust entering the inside of the accommodating space can quickly settle, thereby greatly reducing the problem of dust flying during the feeding and discharging process. At the same time, by controlling the movement of the push plate 31 in the accommodating space, the materials 7 can be pushed out of the semi-enclosed space through the discharging port 22, thereby ensuring the transportation of the materials 7.
[0038] Further, the discharging device 1 in the present disclosure can comprise a feeding hopper 23 opposite to the feeding port 21 and connected to the top of the housing 2, and the feeding hopper 23 can communicate with the accommodating space through the feeding port 21.
[0039] The cross-sectional area of the feeding hopper 23 can increase in a direction away from the feeding port 21, so as to facilitate the material 7 to enter the accommodation space through the feeding hopper 23, and meanwhile, the problem that dust in the material 7 is blown around due to the feeding port 21 being too large can be reduced or avoided.
[0040] In the embodiments of the present disclosure, the moving distance of the push plate 31 can be designed not as the length of the cavity, that is, the moving distance of the push plate 31 in the present disclosure can be less than the distance from the side wall of the shell 2 away from the discharging port 22 to the discharging port 22. By reducing the moving distance of the push plate 31, the stability of the overall structure of the discharging device 1 can be facilitated.
[0041] Specifically, as shown in Figure 1 and Figure 2 The feeding port 21 can include a first side 211 close to the discharging port 22 and a second side 212 away from the discharging port 22. The moving distance of the push plate 31 in the accommodation space can be the distance between the second side 212 and the side wall of the shell 2 away from the discharging port 22. By reducing or avoiding the material 7 from falling into the accommodation space on the side of the push plate 31 away from the discharging port 22 during the movement of the push plate 31, and causing part of the material 7 to fail to be discharged under the pushing of the push plate 31, the moving stroke of the push plate 31 can be avoided to be the length of the accommodation space (i.e., the total length of the accommodation space from left to right), so as to reduce the stroke of the push plate 31, thereby facilitating the stability of the overall structure of the discharging device 1. In addition, by avoiding the material 7 from falling into the accommodation space on the side of the push plate 31 away from the discharging port 22, the cleaning of the accommodation space on the side of the push plate 31 away from the discharging port 22 can be reduced or avoided, so as to reduce the workload of cleaning the inside of the accommodation space. Figure 1
[0042] Further, the side periphery of the push plate 31 can be completely fitted with the inner side wall of the shell 2, so as to reduce the case that dust in the material 7 enters the accommodation space on the side of the push plate 31 away from the discharging port 22 through the gap between the push plate 31 and the inner side wall of the shell 2. However, the side periphery of the push plate 31 can not be completely fitted with the inner side wall of the shell 2, which can be determined according to actual conditions.
[0043] In the embodiments of the present disclosure, the through hole 24 can be arranged on the side wall of the shell 2 away from the discharge port 22. Meanwhile, the discharge device 1 can include a push rod 32 and a power member 33. The push rod 32 is partially located outside the shell 2 and partially extends into the shell 2 through the through hole 24 and is connected with the push plate 31. The power member 33 is arranged outside the shell 2 and is connected with the push rod 32, so as to drive the push rod 32 to move in the accommodation space, and thus the shell 2, the push plate 31, the push rod 32 and the power member 33 form a piston type pushing cavity structure. The driving member and the push rod 32 drive the push plate 31 to push the material 7 towards the discharge port 22 and complete the discharging.
[0044] For example, the power member 33 in the present disclosure can adopt one of hydraulic mechanism, pneumatic mechanism and motor mechanical structure, or a combination of at least two of them, but is not limited thereto. Other power members 33 that can drive the push plate 31 to move back and forth in the accommodation space can also be included in the embodiments of the present disclosure.
[0045] It should be noted that the present disclosure can set a time interval according to the volume of the semi-closed space formed between the shell 2 and the push plate 31 and the feeding amount of the feeding port 21. When the material 7 in the semi-closed space is slightly smaller than the volume of the semi-closed space (i.e. when the material 7 is about to fill the semi-closed space), the push plate 31 is controlled to move back and forth in the accommodation space, so as to push the material 7 towards the discharge port 22. This can not only ensure the maximum efficiency of the pushing, but also avoid the problem of internal blockage of the semi-closed space caused by the accumulation of the material 7. In addition, the present disclosure can control the automatic movement of the push plate 31 in the accommodation space within the set time interval, so as to realize the automation of the discharging process, reduce the labor cost, and improve the uniformity of the discharging.
[0046] It should be understood that the push rod 32 in the present disclosure is connected with the push plate 31 through the through hole 24 on the side wall of the shell 2 away from the discharge port 22. When the push plate 31 moves back and forth in the accommodation space, the push rod 32 also moves relative to the side wall where the through hole 24 is located. In order to facilitate the movement of the push rod 32, the area of the through hole 24 in the present disclosure should be greater than the cross-sectional area of the push rod 32.
[0047] For example, when the through hole 24 is a circular hole, the push rod 32 can be a cylindrical push rod 32, and the diameter of the cylindrical push rod 32 is smaller than the hole diameter of the circular hole.
[0048] Due to the fact that the area of the through hole 24 is greater than the cross-sectional area of the push rod 32, a gap is formed between the push rod 32 and the inner side wall of the through hole 24. The dust in the accommodation space is easy to escape to the outside of the accommodation space through the gap, so that the factory production line dust problem may also occur.
[0049] In order to avoid the above-mentioned situation, the present disclosure can arrange a negative pressure dust removal system 4 outside the shell 2, so as to at least adsorb the escaped dust.
[0050] Specifically, the negative pressure dust removal system 4 in this disclosure can be installed on the top surface of the side wall where the through hole 24 is located to adsorb dust escaping from the through hole 24, thereby reducing or avoiding dust problems in the factory production line.
[0051] It should be noted that the negative pressure dust removal system 4 in this disclosure can be a single-point negative pressure dust collection system, that is, the negative pressure dust removal system 4 in this disclosure can include only one dust collection point, but is not limited thereto, the negative pressure dust removal system 4 in this disclosure can also include multiple dust collection points.
[0052] For example, the negative pressure dust removal system 4 in this disclosure may include multiple dust collection points. Since the gap formed between the through hole 24 and the push rod 32 is small, the amount of dust escaping from the through hole 24 is also small. Therefore, in addition to setting dust collection points near the through hole 24, the negative pressure dust removal system 4 in this disclosure may also set dust collection points at other locations where dust drift may occur. All dust collection points are integrated into the negative pressure dust treatment system in the workshop for unified treatment, so as to reduce dust problems on the factory production line.
[0053] like Figure 3 As shown in the present embodiment, the discharge device 1 may further include a flexible dust baffle 5. The flexible dust baffle 5 is disposed on the upper part of the discharge port 22 to cover part of the discharge port 22, thereby avoiding the problem of some dust escaping during the process of pushing the material 7. At the same time, the flexible dust baffle 5 can also reduce the impact of external airflow on the material 7 inside the outer shell 2, which is conducive to dust sedimentation.
[0054] Specifically, the flexible dustproof component 5 can be made of at least one material, such as cloth or rubber, but is not limited to this. The present disclosure can also use other flexible materials other than cloth or rubber to make the flexible dustproof component 5, thereby forming a semi-enclosed space with the outer shell 2 and the push plate 31, and reducing the adverse effects of external airflow on dust deposition in the accommodating space.
[0055] The flexible dust-blocking component 5 in this disclosure may include multiple discontinuous flexible dust-blocking blocks. These flexible dust-blocking blocks may be made of cut, discontinuous materials such as cloth or rubber. The shapes of each flexible dust-blocking component 5 may differ, but are not limited to these; the shapes of each flexible dust-blocking block may also be the same, depending on the specific circumstances.
[0056] Furthermore, the sum of the height H1 of the flexible dust block in this disclosure and the height H2 of the material 7 at the corresponding position can be equal to or approximately equal to the height H3 of the accommodating space, that is: H1+H2≌H3.
[0057] Specifically, when the flexible dust blocking piece 5 comprises a plurality of discontinuous flexible dust blocking blocks, a plurality of flexible dust blocking blocks of different shapes can be arranged at the discharge port 22, so that the formed flexible dust blocking piece 5 presents a concave upward shape at a certain position. For example, when the center of the feeding port 21 coincides with the center line of the top surface of the shell 2, the flexible dust blocking piece 5 can be arranged in a structure with a concave upward middle part, so that the sum of the height of the material 7 and the height of the corresponding position of the flexible dust blocking piece 5 during the discharging process is equal to or approximately equal to the height of the accommodation space, so as to reduce or avoid the flexible dust blocking piece 5 from colliding with the material 7 during the discharging process, thereby reducing or avoiding the risk of the flexible dust blocking piece 5 damaging the material 7.
[0058] In the embodiments of the present disclosure, the discharging device 1 can further comprise a water spraying dust removal device 6 arranged at at least one of the feeding port 21 and the discharge port 22. During the feeding and discharging processes, water and water mist can be sprayed by controlling the water spraying dust removal device 6, so as to wet the material 7 and capture dust in the air, reduce the scattering of dust in the material 7, and further reduce the dust problem of the factory production line.
[0059] It should be noted that when the discharging device 1 comprises the water spraying dust removal device 6, the water sprayed by the water spraying dust removal device 6 will not affect the material 7.
[0060] Specifically, the water spraying dust removal device 6 in the present disclosure can be one of a shower and an atomizer, but is not limited thereto, and other devices that can uniformly spray water to the feeding port 21 and the discharge port 22 to absorb dust can also be included in the embodiments of the present disclosure.
[0061] In the embodiments of the present disclosure, the material 7 can be bamboo fiber, and at this time, the dust in the material 7 can refer to small fibers and lignin in the bamboo fiber. However, the discharging device 1 in the present disclosure can also be used for discharging and dust removal of materials 7 other than bamboo fiber.
[0062] In addition, in the description of the present disclosure, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.
[0063] It should be noted that "upper", "lower" and the like are only used for differentiation and convenience of description, and do not limit the embodiments of the present disclosure in terms of position, for example, the "upper" can be "lower" in actuality. In the present disclosure, unless otherwise explicitly specified and limited, the terms "assembly", "connection" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or can be integrated; can be mechanical connection, can also be electrical connection; can be direct connection, can also be indirect connection through an intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.
[0064] In the description of the present specification, the description referring to the terms "some embodiments", "exemplarily", and the like means that the specific features, structures, materials or characteristics described in connection with the embodiments or examples are included in at least one embodiment or example of the present disclosure. In the present specification, the illustrative expressions of the above terms are not necessarily directed to the same embodiments or examples.
