[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] One embodiment of this application provides a height-adjustable mechanism for a dust removal air knife, such as... Figures 1-4 As shown, it includes: a support frame (1), which provides support;
[0026] The support frame (1) is provided with dust removal air knife mounting support units (2) on both sides respectively; a dust removal air knife body (3) is connected between the two dust removal air knife mounting support units (2). It should be noted that the structure of the dust removal air knife body (3) is the prior art, and will not be described in detail here; the focus of this application is: how to adjust the height of the dust removal air knife body (3);
[0027] The support frame (1) is provided with limiting units (4) on both sides respectively. The dust removal air knife installation support unit (2) cooperates with the limiting unit (4). The limiting unit (4) is used to limit the stroke of the dust removal air knife installation support unit (2).
[0028] The support frame (1) is provided with adjustment units (5) on both sides. The adjustment units (5) are connected to the dust removal air knife installation support unit (2). The adjustment units (5) drive the dust removal air knife installation support unit (2) to move up and down relative to the support frame (1), thereby realizing the height adjustment of the dust removal air knife installation support unit (2).
[0029] Specifically, in this embodiment, such as Figure 4 As shown, the dust removal air knife mounting support unit (2) includes a first support plate (21) and a second support plate (22) spaced apart. The first support plate (21) and the second support plate (22) are connected by a third support plate (23), which is horizontally arranged. The first support plate (21) and the second support plate (22) are respectively connected to the dust removal air knife body (3). The overall structure is simple and easy to operate.
[0030] Specifically, in this embodiment, the limiting unit (4) includes a first limiting plate (41) and a second limiting plate (42) spaced apart, the first limiting plate (41) and the second limiting plate (42) being parallel; the first limiting plate (41) being horizontally positioned; and the third support plate (23) being located between the first limiting plate (41) and the second limiting plate (42) for limiting the travel of the third support plate (23).
[0031] Specifically, in this embodiment, such as Figures 3-4 As shown, the adjustment unit (5) includes an adjustment screw (51) rotatably connected to the support frame (1) via a first bearing (53) and a connecting nut (52) connected to the third support plate (23). The upper and lower ends of the adjustment screw (51) are respectively connected to the support frame (1) via the first bearing (53). For ease of connection, the lower end of the adjustment screw (51) is connected to the second limiting plate (42) via the first bearing (53). The adjustment screw (51) is vertically arranged. The adjustment screw (51) is threadedly connected to the connecting nut (52). By rotating the adjustment screw (51) forward or backward, the connecting nut (52) is driven to move upward or downward on the adjustment screw (51), thereby realizing the rise or fall of the dust removal air knife body (3) connected to the third support plate (23) relative to the support frame (1).
[0032] To facilitate the synchronous operation of the two adjustment units (5), a linkage unit (6) is also included, and the two adjustment units (5) are connected through the linkage unit (6). The linkage unit (6) includes a linkage member (62) rotatably connected to the support frame (1) through a second bearing (61). The two sides of the linkage member (62) are respectively connected to a first transmission gear (63). The adjustment screw (51) is connected to a second transmission gear (64) that meshes with the corresponding first transmission gear (63). One end of the linkage member (62) extends to the outside of the support frame (1), and one end of the linkage member (62) is connected to a knob (65) for easy rotation. The support frame (1) is provided with a digital position display (66). The digital position display (66) is a mechanical digital position display, and its structure is existing technology, which will not be described in detail here. One end of the linkage member (62) passes through the mounting shaft hole of the digital position display (66) and is connected to the knob (65).
[0033] In one embodiment, such as Figure 4 As shown, a guide shaft (43) is connected between the first limiting plate (41) and the second limiting plate (42). A flange bearing (44) is slidably connected on the guide shaft (43). The flange bearing (44) is connected to the third support plate (23) to ensure the stability of the dust removal air knife body (3) when it is raised and lowered.
[0034] In one embodiment, such as Figure 4 As shown, the support frame (1) is provided with a limiting guide groove, which is composed of two spaced limiting blocks (7) connected to the support frame (1); the frame formed by the first limiting plate (41), the second limiting plate (42) and the third support plate (23) is adapted to the limiting guide groove, so that the dust removal air knife installation support unit (2) does not deviate during the movement.
[0035] In use, rotate the knob (65) to drive the connecting rod (62), which in turn drives the first transmission gear (63), which drives the second transmission gear (64), which in turn drives the adjusting screw (51). The rotation of the adjusting screw (51) causes the connecting nut (52) to move up and down, thereby raising and lowering the position of the dust removal air knife body (3). The amount of movement of the dust removal air knife body (3) is confirmed by the digital position display (66).
[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0037] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0038] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0039] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0040] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" 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 a connection within 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.
[0042] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
